Abstract: 346,007. Totalizators. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, Liverpool, SIMPSON, L. M., The Bungalow, Laurel Bank, Stanks, near Leeds, and PEARCE, O. A., 23, Stainburn Avenue, West Derby, Liverpool. Jan. 1, 1930, No. 79. Drawings to Specification. [Class 106 (i).] Routine testing apparatus.-The central equipment of an electric totalizator is automatically tested by an assembly of relays and rotary switches which simulate the effects of entering a bet at each ticket-machine on each horse in turn. The horse counters are thus tested one after another and means are provided whereby if a horse total does not agree with the grand total the testing action ceases and an alarm and indicating lamps are energized to enable the locality of the fault to be readily determined. The particular apparatus described and illustrated is for testing the decoding and counting equipment of Specifications 331,500, [Class 106 (i), Calculating &c.], and 342,261, and includes a number of pre-selector switches functioning to select the counters and to connect them in sequence with the ticket-machine leads. To expedite the test, say for a 100-machine installation with accommodation for win and place bets on 80 runners, there are eight horse access switches to connect with the counters and five machine access switches, these latter being adapted to work simultaneously but independently to direct impulses as from each of twenty machines in turn. The revertive control may be tested when the first signals are sent as from the machines but subsequently the test of this control is omitted so that the remaining tests may be performed more quickly. Transfer from the thousands denominations is tested by giving two rotations to auxiliary switches one of which is adapted to set up bets of 20000 units. By means of keys, variations in the testing procedure may be introduced. Thus win or place counters or both may be tested, a test on a selected counter only may be continuously applied, a fault may be noted only and the test continued on the remaining units and the efficiency of the collecting switches may be tested.

Title: Process for the production of substitution products of acid nitriles
Filed: 1931-12-14
Abstract: alkyl, aralkyl, and non-aromatic isocyclic residues are introduced into the a -position of acetonitrile and its mono- or di-substitution products by treating the nitriles with sodamide in the presence of halogen compounds of the above-mentioned residues. The residues to be introduced may themselves be substituted by such other atoms or groups of atoms as do not react with sodamide, or only react very slowly under the conditions of the reaction, e.g. by alkoxy, aryloxy, arylmercapto, substituted amino groups or halogen atoms.  The sodamide used may be finely divided, and may be mixed with an indifferent solid, such as sodium chloride or sulphate.  The process may be conducted in the presence of indifferent diluents such as benzene, and temperature regulation may be facilitated by using a rotary drum.  The examples illustrate the preparation of diethyallyl-, benzyldiethyl-, cyclohexenyl-diethyl-, n-butyldiethyl-, isopropyldiethyl-, allylmethyldiethyl, ethyldiisopropyl-, allyl-dimethyl-, triethyl-, triallyl-, allylmethylethyl-, diethylallyl-, dibutyl-, dibenzyl-, allyl-, diethyl-, methylethyl-, diethylaminotriethyl-, benzyl-ethylphenoxyethyl-, diallyl-, dipropyl-, butyl-, isopropylethylallyl-, and secondary butyl-acetonitrile, dibenzyl-, benzyl-, dipropyl-, and propyl-propionitrile, diallyl-, g -phenyl-, butyl-, dibutyl-, isopropyl-, a a -dimethyl-, g -methoxy-, g -phenoxy-2-ethyl-, di-g -phenoxy-2-ethyl-, and a a -dimethyl-g (p-tolylmercapto)-butyronitrile, diallylisovaleronitrile, n-caproic acid nitrile and its dioctyl derivative, n-capric acid nitrile, n-stearic acid nitrile, hydrocinnamic acid nitrile, a a -dimethyl, a -chlorovaleronitrile, 1-cyan-1-benzyl-2-methylcyclohexene-4, and 2-butyl-2-cyan-3-methyl - 1 : 4 - endomethylene - cyclohexene-5.  The Specification also refers to the preparation by hydrolysis of the amides corresponding to some of these amides and of diethylacetic acid.  In the Specification as open to inspection under Sect. 91 it is stated that the diethylacetonitrile could be converted to known derivatives of bromo-diethylacetic acid, and that isopropyl butyronitrile could be converted to isopropyl bromobutyramide; this subject-matter does not appear in the Specification as accepted.
