Title: Improvements in and connected with advertising apparatus
IPC: G09F11/295
Filed: 1931-05-27
Abstract: 388,411. Changing signs. WALKER, M., WALKER, M. M., Mansefield House, and CLARK, G. M., 6, Stuart Terrace, both in Bathgate, West Lothian. May 27, 1931, No. 15465. [Class 3 (i).] A display band K is wound on and off two rollers D, E each of which has mounted on its shaft F, G an electric motor 30, 30A. Lamps 29, 29a behind the band are switched on when the band is stationary and off when in motion. The motors 30, 30A have tapered polepieces and are controlled by a selective switch S which is thrown over by mechanism actuated by a shaft L rotated by a pinion wheel 25 gearing with a perforated metal strip 26 fixed to one edge of the band K. The mechanism comprises a worm N on the shaft I. rocking a lever O, Fig. 6, pivoted at P and carrying adjustable contacts R, R<1> in horns Q<1>, Q<2>. One or the other contact R, R<1> touches an arm T pivoted at S, the outer end of the arm T making contact with one or the other of terminal springs U, U<1>. A snap-over spring j, j connects the arm T and the lever O. The time of exposure of a display is determined by a geared rotary air fan a, Fig. 4, connected to a double switch S<1>, S<2>, which is opened by an electromagnet M<1> and closed by the retraction of a spring 15A. A double switch is employed to allow part to close and to open before the other part to prevent magnet M<1> opening the whole switch too early and stopping the motor. To obtain even spacing of the band K, brake-drums H, J are mounted on the roller shafts F, G, brakeblocks 27, 27A being forced thereagainst by pivoted cams w, w<1>, Fig. 2, under control of a magnet M<3>. A magnet M<5> switches the lamps 29, 29A on and off under control of switch S<1>, The band K may have cross strips to form pockets to receive announcements &c.

Title: Electrical device for checking the receiving circuits of inductor-type signal-repeater systems upon railways
IPC: B61L3/12
Filed: 1939-05-26
Abstract: 529,282. Track-actuated train signalling apparatus. SOC. FRANCAISE METRUM. May 26, 1939, No. 15680. Convention date, Aug. 3, 1938. [Class 105] Cab-signalling apparatus of the inductive receiver type is arranged to give warning of any failure by providing a checking current which flows to the midpoint of the winding W of the receiver core M and to the midpoint of the winding of the receiver relay E thereby avoiding the production of fluxes. The checking current also flows through a checking relay K. The receiver is thus unaffected by stray iron but at a track signalling point the receiver relay E is operated thereby opening its back contact E1 in the circuit to the main relay P which therefore drops and gives the signal ; the relay P remains dropped, since its circuit includes the stick contact P1. Breakage of a wire would either cause the receiver relay E to become effective by its half winding or the relay K would be dropped and so open contact K1 in the circuit to the main relay P.

[Also in Division H5] In a plant for irradiating batches of articles in containers 13, Fig. la, on an endless conveyer 10, the movement is periodically interrupted for preselected intervals of time in order to control the radiation dose without running the conveyer continuously at low speeds. The electric motor 20 driving the conveyer is controlled from a switch 30 having a roller 31 engaged by spaced projections 11 on the conveyer and is associated with a time base (36), Fig. 1c (not shown), which controls the switchedoff period.

The containers 13 are fed singly to the conveyer on an inclined roller way 15 and are hooked in pairs on spaced support bars 12. They are discharged singly under their own momentum down an inclined roller way 17 at the side of the roller way 15 and the containers remaining on the support bars 12 are successively pushed to one side to permit the next container to be received from the roller-way 15.
Patent GB-379709-A (GB)
Title: Improvements in process of manufacturing thiazole derivatives
Filed: 1931-06-02
Abstract: Nitroaryl-arylthiazyl sulphides are prepared by treating a mercaptoarylthiazole with a nitrochlorbenzene in the presence of an aqueous reaction medium in which one of the reacting components is substantially insoluble and which contains no organic liquid. Solvent losses are thus eliminated and high and uniform yields of product are obtained in minimum time.  In examples, (1) 2 : 4-dinitrochlorbenzene is added to a weak alkaline solution of 2-mercaptobenzthiazole and the mixture heated at 60-70 DEG  C. with agitation, for example in a ball mill.  The sulphide is obtained in almost theoretical yield; (2) the above details are modified by adding the dinitrochlorbenzene in the molten state slowly to the alkaline solution. Mercaptobenzthiazole, mercaptotolylthiazole and mercaptoxylylthiazole may be reacted with other nitrochlorbenzenes, such as 1 : 4-nitrochlorbenzene or 2 : 4-dichlornitrobenzene.  The process may be employed for preparing a suitable mixture for accelerating the vulcanization of rubber. Thus diphenylguanidine hydrochloride is added to an alkaline solution of mercaptobenzthiazole and molten 2 : 4-dinitrochlorbenzene added to the hot solution.  The reaction proceeds at 60-70 DEG  C. with continuous mixing in a ball mill, and a further addition of caustic soda until a finely divided mixture of the guanidine and sulphide is obtained; the diphenylguanidine may be replaced by other amines.ALSO:A mixture suitable for use as an accelerator of the vulcanization of rubber is prepared as follows:-diphenylguanidine hydrochloride is added to an alkaline solution of 2-mercaptobenzthiazole and the mass heated to 60-70 DEG C.  Molten 2.4-dinitrochlorbenzene is then added, and the mixture agitated in a ball mill, with further addition of alkali until a finely divided mixture of diphenylguanidine and 2.4-dinitrophenyl-benzthiazyl sulphide is obtained; other amines may be employed instead of diphenylguanidine.
