Title: Apparatus for printing tickets
IPC: B41K3/44
Filed: 1971-05-04
Abstract: 1323002 Printing tickets SODECO SOC DES COMPTEURS DE GENEVE SA 4 May 1971 [11 May 1970] 12835/71 Heading G4T [Also in Division B6] A ticket cut from a web of ticket material at a first station is clamped against an outer, partcylindrical surface of a rotatable member mounted at the free end of a rotatable arm, and the arm and member are then rotated to cause the ticket to move in a hypocycloidal path from the cutting station and through successive printing stations to a discharge station. As shown (Fig. 2), the arm 8 rotatable about 9 carries the rotatable member in the form of a drum D. A pinion 39 fixed to the drum meshes through pinion 45 with a fixed toothed ring 40, the gear ratios being such that the ticket moves hypocycloidally. Ticket material 42 (Fig. 3), entering the cutting station, trips an arm 20 to stop further feeding of the material. A gripper 22 grips the leading ticket end against a platen 21, mounted on the drum D. As the drum rotates, a guide 32 presses the remainder of the ticket against the platen until finally the trailing ticket end is gripped by a gripper 23. Grippers 22, 23 and guide 32 are moved to and from their operative positions at appropriate times by axially-reciprocatable, shaped, cam rods 28, 36, whose lower ends co-operate with a fixed cam ring 41 (Fig. 2). The printing stations (not shown) are arranged in a part-circular array (Fig. 1) and their printing surfaces are inked immediately before passage of the ticket. For this purpose, a frame 46 pivoted at A carries an inking roller 48 fast with a pinion 49, driven by the pinion 39 via a pinion 50. A pre-inked roller 51 is spring-urged towards roller 48, the spring force being adjustable at 60. A spring 63 pivots the frame 46 about A to urge the roller 48 against the printing surfaces. A camway 67 coacts with a lug 66 to pivot the frame against the action of spring 63 at selected locations, where no printing (and consequently no inking of the printing surfaces) is required.

Abstract: 567,134. Automatic gain control. STANDARD TELEPHONES & CABLES, Ltd. .Aug. 13, 1943, No. 13149. Convention date, Aug. 18, 1942. [Class 40 (v)] Instability of operation of an unbalanced push-pull amplifier due to the action of an automatic gain control potential is reduced by introducing into the circuit a degree of unbalance greater than the inherent unbalance and in a sense to produce de-generation with respect to the automatic gain control circuit. Signals from a source 10 are fed to the grids of a pair of push-pull amplifiers 4, 5, the output from which is fed through amplifiers 34, 35 to a transformer 37 feeding a load 42. A secondary coil 43 feeds a full wave rectifier 46 having a delay bias 51 to provide a gain control potential which is fed over lines 45 to the ends of a resistance 21 in the common portion of the grid circuits of valves 4, 5. A condenser 63 limits the suddenness of the action of the A..G.C. potential. To prevent instability due to lack of balance between the valves 4, 5, a resistance 60 is introduced into the anode cathode circuit of one of the valves according to the direction of unbalance. The resistance has an effect greater than the inherent unbalance and is placed so as to produce degeneration with respect to the A.G.C. potential.

IPC: C07D277/40
Filed: 1941-10-17
Abstract: 557,289. 2-Aminothiazole compounds. MONSANTO CHEMICAL CO. Oct. 17, 1941, No. 13380. Convention date, Oct. 29, 1940. [Class 2 (iii)] 2-Aminothiazole compounds are prepared by reacting thiourea with a haloacetal in the presence of water and a lower aliphatic alcohol. The preferred haloacetal is chloroacetal. This may be used either in the form of a pure compound, or as the crude reaction product resulting from the chlorination at a low temperature of vinyl acetate in ethyl alcohol. The alcohol is preferably present in at least equimolecular proportion. In examples (1) Distilled chloroacetal is dropped into an aqueous-alcohol solution of thiourea. After several hours under reflux the 2-amino-thiazole is extracted; (2) Crude 1:2-dichloroethyl acetate is heated with ethyl alcohol and an aqueous-alcohol solution of thiourea is added and kept at 70‹-75‹C. for 4 hours ; (3) An ethyl alcohol solution of vinyl acetate is chlorinated at a low temperature and the product treated with an aqueous-alcohol solution of thiourea to give 2-amino-thiazole. The 2-amino thiazole may be extracted by direct extraction by benzene or carbon tetra-chloride, or by extraction with water and distillation, or by salting out from water, or by steam distillation, or by distillation with superheated steam, or by, batch distillation in vacuo. The preferred method of extraction however which eliminates decomposition is a flash distillation performed by bringing the crude 2-amino thiazole into contact with a heated surface maintained at a substantially constant temperature.
