Abstract: 1,083,532. Automatic exchange apparatus. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 13, 1966 [May 17, 1965], No. 21298/66. Heading H4K. The duplicated portions of a control circuit for a telephone exchange are switched into service alternately by means of the circuit illustrated which forms part of one of the control circuit portions. A bi-stable 12 switches its associated control portion in and out of service. Monostable circuits 2a and 2b, in the O condition when at rest, gate the 1 condition of bi-stable 3a so as to set bi-stable 12 to its 1 condition by clock pulses 7. The pulse setting 12 also sets 2a and resets the bi-stable corresponding to 12 in the other duplicate portion of the control circuit so as to switch it out of service. When monostable 2a falls back, having reset 3a and set 3b, the set state of 3b is gated to set monostable 2b. The time constant of 2b is made longer than 2a so that 2b is reset from the associated duplicate portion, where a circuit identical to that illustrated exists, before it resets itself supposing that the circuits are functioning normally. The pulses gated over 6b to set 2b, and the pulses gated over 6a to set 2a, are applied to an alarm circuit AL which operates in the absence of the pulses.

Indicating, optical devices for.-A device for determining the mean reading of two scales or scale images disposed adjacent to one another comprises a translucent diagonal scale displaceably mounted relatively to the main scales and provided with a reading index line or lines extending from the zero indication of the scale and parallel to the main indications. The diagonal scale is graduated so that a minute division on the scale subtends two minutes on the main scales; it is marked or engraved on a sheet of glass 1, Fig. 1, mounted in an eye-piece frame 2 and adjustable by means of a knob 3. As shown in Fig. 2, the diagonal scale is constituted by lines 8 - - 10 with reading index lines 11 at one end which can be brought into coincidence with the nearest coarse graduation oi the projected main scales 4 or 5. The true mean reading is obtained on the diagonal scale by setting the actual or virtual index 7 to the left of the lines 11 and by reading to the lower scale division immediately to the left of the index 7. The diagonal scale may be twice the length of any two coarse graduations to avoid errors in reading and it may be displaceably mounted in two directions at right angles so as to bring it to the position shown in Fig. 8 thereby facilitating the reading of the minute divisions. The diagonal scale may take the form of a single inclined line 11, Fig. 9, subdivided by lines 12. In use with circular main scales the lines 10 of the diagonal scale will not be parallel but will radiate in accordance with the curvature of the main scales.

Title: An improved servo-brake
IPC: B60T13/66
Filed: 1925-08-27
Abstract: 239,225. Compagnie Internationale des Freins Automatiques Soc. Anon., (Assignees of Pieper, M. H.). Aug. 28, 1924, [Convention date]. Fluid-pressure.-In direct-acting fluid-pressure brakes for a train of vehicles of the type provided with braking means comprising on each vehicle a gas under pressure acting on a liquid which displaces a piston connected to the brakes, and releasing means restoring said braking means into their initial position by the action of a partial vacuum transmitted throughout the length of the train, the brakes being held in the released position by catch devices which may be withdrawn to enable the brakes to be applied, a single lever controls the action of the braking and releasing means and of the catch devices. As shown in Fig. 2, the brakes are released by creating a partial vacuum in a train pipe 57 by means of a steam ejector 56 under the control of a driver's valve 58. With this valve in the release position shown, the circuit of a solenoid 68 is closed by the engagement of an arm 64 with a contact strip 63, whereby a valve 69 is held open to permit the ejector to operate until all the brakes are released, the circuit then being broken by a cut-out switch 66. 67, one of which is fitted to each vehicle. In this position the arm 64 and strip 63 serve also to close the circuit of a solenoid 61 controlling a valve 8, so that the valve opens to permit the passage of pressure fluid from the brake cylinder 1 to a reservoir 6 containing compressed air in its upper part only when the action of the vacuum on the piston 1<a> overcomes the force of the solenoid. When the brakes are fully released the valve 8 moves to its seat to prevent return of the actuating-fluid to the brake cylinder. When the valve is moved towards the application position s, the arm 64 leaves the strip 63, so that the circuits of the solenoids 68, 61 are both opened, whereby the valve 69 remains closed to prevent operation of the ejector 56, and the valve 8 is opened by its spring 62. In the position o the vacuum is retained in the train pipe 57, so that the brakes are still held released, but when the position s is reached, the train pipe is connected to atmosphere at 71, and the actuating- fluid passes from the reservoir 6 to the brake cylnder to apply the brakes. In a slightly inodified form, the valve 69 is dispensed with, the working of the ejector being controlled wholly by means of a port in the driver's valve, which also serves to connect the pipe 57 to atmosphere in the application position of the valve. Specification 226,830 is referred to. The Specification, as open to inspection under Sect. 91 (3) (a; comprises also the use generally, on a train cf vehicles, of a partial vacuum, created on one of them for releasing the brakes throughout the train, the brakes being of the type employing a reserve of energy on each vehicle, the energy expended being restored upon each brake release. This subject-matter does not appear in the Specification as accepted.

Title: The preparation of ª‡-aminoacids
Inventor: HEILBRON IAN
IPC: C07D277/20
Filed: 1948-08-18
Abstract: a -Aminoacids of formula <FORM:0666226/IV (b)/1> are made by reducing the intermediate <FORM:0666226/IV (b)/2> in an acid medium using an acid reducing agent.  The intermediate is made by condensing R2COR1, or an equivalent thereof, with 2-thio-5-thiazolone.  In the above formul  R1 and R2 are the same or different and may be hydrogen, alkyl, aryl or aralkyl groups optionally containing an imidazole substituent or members of a carbocyclic or heterocyclic ring structure and may contain functional substituents.  "The equivalent" is defined as a similar compound, e.g. an acetal or ketal, in which there is linked to the C atom, besides R1 and R2, one or more reactive atoms or groups which will react with the H atoms in the 4-position of the thiazolone, thus causing the double bond in the intermediate.  The condensation may be effected with acidic or basic catalysts and in solvents which may be in excess of the carbonyl compound.  Catalysts specified are acetic acid containing HCl, morpholine or piperidine and if the carbonyl compound is acidic or basic it will itself serve as catalyst.  The preferred reducing agent is phosphorus and HI although zinc and acetic acid is also mentioned. In examples 2-thio-5-thiazolone is condensed with (1) acetone in morpholine or acetic acid to yield 4-isopropylidine - 2 - thio - 5 - thiazolone which is reduced to valine with phosphorus and HI; (2) isobutyraldehyde in piperidine to yield 4-isobutylidene-2-thio-5-thiazolone which is reduced to leucine; (3) with benzaldehyde in morpholine, ethanolic HCl or acetic acid and HCl to yield benzylidene-2-thio-5-thiazolone which is reduced to phenylalanine; (4) with p-hydroxybenzaldehyde in acetic acid and piperidine to yield 4-p-hydroxybenzylidene-2-thio-5-thiazolone which is reduced to tyrosine; (5) with cyclohexanone in acetic acid and piperidene to yield 4-cyclohexylidene-2-thio-5-thiazolone which is reduced to cyclohexylglycine with red phosphorus and HI; (6) with b : b -diethoxyethyl methyl sulphide in acetic acid and piperidine to give 4-b -s-methylidene-2-thio-s-thiazolone which is reduced to methionine with red phosphorus and HI in acetic acid, and (7) with 4-imidazolylaldehyde in acetic acid to give 4 : 41-imidazolidene-2-thio-5-thiazolone which was reduced to histidine picrate and dihydrochloride by treatment with HI and red phosphorus in acetic acid anhydride solution followed by treatment with the appropriate acid.
