Filed: 1938-08-25
Abstract: 518,542. Multi-colour printing ; photoelectric apparatus. SHURLEY, F. Aug. 25, 1938, No. 25055. [Class 40 (iii)] [Also in Group XVI] Relates to machines for multi-colour printing on bottles and the like of the kind in which the bottles are held by rotatable chucks which. have to be stopped in such a position that the bottles are presented to the press in correct position to ensure registration of successive prints. According to the invention, a brake is adapted to be applied directly to a chuck by an adjacent electromagnet. As shown in Fig. 4, the chuck 7 is fastened to a shaft 10 and cushioned by springs 24, and a plate 17 with a lining 20 is fastened to the end of the shaft. The end of the bottle A fits in the mouth of the chuck and against the lined plate 17. The shaft 10 is journalled in ball bearings 9, 12 in a carrier 4. The end of the shaft opposite the chuck is formed with a screw-thread 10a on which is fastened a collar 33 to which is attached a flat annular spring 35. A ring of magnetic material 8 is secured at its periphery to the periphery of the spring 35 and is fitted with a brake pad 37 bearing on a non-magnetic brake disc 32 mounted against an electromagnet 31 situated around the shaft 10 and fastened to the carrier 4. The chuck 7 is adapted to be rotated by a friction wheel 25a, and the rotation is stopped by the energization of the electromagnet causing the application of the brake 37, 32. The machine in which the above braking device is used comprises a shaft 1, Figs. 1 and 3, extending between fixed frames 2, 2 and rotated in steps of a quarter revolution by a Geneva gear. Carriers 3, 4 fastened to the shaft 1 have chucks 5, 7, respectively, between which the bottles A are held, the chucks 5 being cushioned by springs 6 which overpower the springs 24 aforesaid of the chucks 7. A bottle is inserted between a pair of chucks at the bottom position; the shaft and carriers are rotated one step to bring the bottle between a light source 54 and a photo-electric device 52 where the chucks and the bottle are rotated by the friction wheel 25a, until stopped by the electromagnetic brake aforesaid under control of the photo-electric device ; the shaft and carriers are then rotated a second step to bring the bottle opposite the printing press 70 ; and finally the bottle is removed to leave the chucks free to receive a fresh bottle. Connection is established from the photo-electric apparatus to the electromagnets through brushes 48, 48a, contact segments 41, 41a and leads 47, 47a. The photoelectric apparatus is of known kind comprising a valve-relay device operated by the sudden increase of light occurring when a dark impress on the bottle is immediately followed by a transparency during the rotation of the bottle by the chucks. Specification 507,089 describes a similar machine in which the brake mechanism for stopping the chucks is different.

As shown, a ferromagnetic drum 33 is attached to a flywheel 23 of an automotive vehicle engine whilst a ferromagnetic driven member 57 is spring mounted on a hub 49 by vibration dampers 55. Ferromagnetic pole rings 87, 89 are bolted on opposite sides of a ferromagnetic ring 85 carried by a fixed outer member 41. The winding 91 is cooled by water from the engine cooling system introduced at 109 into passages 95, 97, the winding 91 being separated from the cooling water by heat-conductive, lowcarbon iron rings 99, 101. Sealing rings 113 are also provided. Stainless steel particles are introduced into gaps 61, so that when winding 91 is sufficiently energized, transmission of torque between members 33 and 57 is allowed. Freerunning labyrinth seals 69, 71 prevent escape of the magnetizable particles. The engine cooling system maintains the temperature of winding 91 at approximately 200‹ F. hence the torque transmitted is thus proportional to applied voltage.

Abstract: 1431205 Stabilizing bi-stable circuits INTERNATIONAL BUSINESS MACHINES CORP 30 May 1973 [30 June 1972] 25825/73 Heading H3T A FET storage circuit comprises crosscoupled field effect transistors T 1 , T 2  storing binary information and transistors T 3 , T 4  reading out and writing; the latter being held non-conductive for inoperation over word line WL whereby T 1  and T 2  are separated from bit lines B0 B1 and fed from V L  over FET's T 5  and T 6 , whose gates are linked to a circuit supplying a potential dependent on the threshold of the FET's. For read out or write a signal on word line WL drives T 3 , T 4  conductive, so that for read the potentials at points 1, 2 are applied to bit lines B0, B1 and to the read amplifiers; while for write the signals are fed into storage transistors T 1 , T 2  over T 3 , T 4 . Current in T 5 , T 6  must compensate the leakage in T 1 , T 2  respectively and for T 1  conducting and T 2  blocked, the potential of point 2 must be held by current in T 6  compensating leakage current of blocked T 2 , while T 5 , T 6  must have high resistance. Thus the difference between the gate to source voltage and the threshold voltage must be as low as possible, which is achieved by applying to the gate electrodes a potential dependent on the respective threshold voltages of the FET's. The FET's T 7 , T 8 , T 9 , T 10 , T 11  simulate the operation of the connected storage cells with T 8  corresponding to T 6  when T 1  is conducting and T 9  corresponding to transistor T 1  while T 7  determines the current in a chain interconnecting potential V H  and the potential V R ; derived from voltage division by FET's T 10 , T 11  across potentials V L , V H . The potential V G  at 3 = V R  + V T9  + V T8  corresponding to threshold voltages of T 8 , T 9  is applied to the gates of T 5 , T 6 . In a modification (Fig. 2) Vg is developed and fed to the storage cells over an interface stage comprising a further series of FET's; yet another FET being connected into the chain of T 7 , T 8 , T 9  with the interface FET's in series between V H  and earth and their gates energized from the junctions of T 7  and the additional FET and from T 8 , T 9  respectively to develop potential V G  at the junction of the decoupling FET's. Mathematics is given. A further modification (Fig. 3, not shown) derives additional compensation by utilizing another FET stage and also feedback stages.
