Amendment No. 1 to Schedule 13D

   This Amendment No. 1 amends and supplements the Schedule 13D originally
filed by Unitrin, Inc., Trinity Universal Insurance Company and United
Insurance Company of America, dated November 3, 1997. Terms used herein and
not otherwise defined have the meanings given such terms in the original
Schedule 13D, dated November 3, 1997.

Item 1.  Security and Issuer

   The class of equity securities to which this Schedule 13D relates is the
common stock, par value $.01 per share (the "Common Stock"), of UNOVA,
Inc., a Delaware corporation (the "Issuer"). The principal executive
offices of the Issuer are located at 21900 Burbank Boulevard, Woodland
Hills, California 91367.

Item 2.  Identity and Background

   For revised information concerning the directors and executive officers
of Unitrin, Trinity and United and for information concerning the directors
and executive officers of Union National Life Insurance Company, a
Louisiana corporation ("Union"), 8282 Goodwood Boulevard, Baton Rouge,
Louisiana 70806, see Schedules UNIT, T, U, and UNL, respectively, to this
Amendment. All persons listed on such Schedules are U.S. citizens.

   No filing person has been convicted in any criminal proceeding
(excluding traffic violations or similar misdemeanors) during the past five
years; nor, to the best knowledge and belief of the filing persons, has
anyone listed in the attached Schedules been convicted in such proceedings.

   To the best knowledge and belief of the filing persons, during the past
five years no filing person nor anyone listed on the attached Schedules was
a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction and as a result of such proceeding was or is subject
to a judgment, decree or final order enjoining future violations of, or
prohibiting or mandating activities subject to, federal or state securities
laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

   Trinity and United were formerly shareholders of Western Atlas Inc.
("Western Atlas"). On October 31, 1997, Western Atlas divested itself of
its wholly-owned subsidiary, Issuer, by means of a pro rata spin-off in
which each shareholder of Western Atlas was distributed one share of Issuer
common stock for each share of Western Atlas common stock held on October
24, 1997, the record date for the spin-off. As a result, Trinity and United
received the same number of shares of Issuer as they held in Western Atlas.
No consideration was paid by Trinity or United for the Issuer shares
reported hereby.

Item 4.  Purpose of Transaction

Item 4 of the original Schedule 13D is hereby restated in its entirety as
follows:

   Unitrin is in discussions with a third party regarding such party's
proposal to provide the Issuer with financing in the form of senior secured
notes of the Issuer, which Unitrin understands would be used to refinance
certain existing debt of the Issuer and its subsidiaries. In connection
with these discussions, Unitrin has indicated its willingness to
participate in any such financing in an amount up to $25 million. In
connection with such financing, Unitrin may also receive warrants to
purchase Common Stock of the Issuer representing up to 5% of the Issuer's
outstanding Common Stock. Neither Unitrin nor the third party has entered
into any binding agreement with the Issuer with respect to such financing.
Any such financing would be subject to the negotiation and execution of
definitive agreements on acceptable terms and customary closing conditions,
including the refinancing or amendment of the Issuer's senior credit
facility on acceptable terms. There can be no assurance that either Unitrin
or the third party will enter into any agreement with the Issuer with
respect to such financing or that any such financing will be consummated or
result in any transaction in the Issuer's securities.

   In connection with Unitrin's evaluation of the Issuer's financing
arrangements and Unitrin's investment in the Issuer, Unitrin may consider,
make proposals with respect to, and/or enter into discussions regarding,
one or more of the transactions and events specified in clauses (a) through
(j) of Item 4 of Schedule 13D, including transactions involving additional
debt or equity financing of the Issuer. There can be no assurance that
Unitrin will take any such actions or that, if taken, any such actions will
be consummated or result in any transaction in the Issuer's securities.

                                                                   Page 7 of 13



Item 5.  Interest in Securities of the Issuer

   Other than the transfer of 1,495,327 shares of Common Stock by Trinity
to Union, a wholly-owned subsidiary of United, none of Unitrin, Trinity,
United or Union has acquired or disposed of any shares of the Issuer's
Common Stock since November 3, 1997, the date of the original Schedule 13D.
However, the collective percentage ownership by Unitrin, Trinity, United
and Union (the "Unitrin Ownership Percentage") of the Issuer's Common Stock
has decreased as the result of a change in the outstanding number of shares
of the Issuer's Common Stock since November 3, 1997. The result of this
change is that the Unitrin Ownership Percentage in the Issuer's Common
Stock has decreased from 23.2% as reported in the original Schedule 13D to
22.5% as of the date of this Amendment.

   To the best knowledge and belief of the filing persons, during the past
sixty (60) days no filing person nor anyone listed on the attached
Schedules has entered into any transactions involving the Issuer's Common
Stock. To the best knowledge and belief of the filing persons, no one
listed on the attached Schedules beneficially owns shares of the Issuer's
Common Stock.

Item 7.  Material to be Filed as Exhibits

     Attached is a copy of an Agreement authorizing Unitrin to file a joint
statement.

                                                                   Page 8 of 13

                                 Signature


   After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete
and correct.
