Title: Improvements relating to printing machines
IPC: B41F3/30
Filed: 1934-01-25
Abstract: 425,502. Printing-machines. KALAMAZOO-PRINT, Ltd., IMPEY, F. L., and RENDALL, A. G., Mill Lane, Northfield, Birmingham. Jan. 25, 1934, No. 2586 [Class 100 (ii)] A printing-machine for printing proof sheets or a small number of impressions from a lithographic or like printing-plate is constructed of a transfer or offset roller b and an impression roller c mounted in lever arms i which are acted on by springs j to move the roller c into contact with the roller b. The arms i can be depressed by a cam n operated by a lever l, but this operation can be effected only when a plunger h is in the position in which it locks the cylinder b. When the cylinder b is thus locked and the cylinder c depressed an inked aluminium or like printing- plate is placed in such a position that perforations in the plate are engaged by fixed studs p mounted on a bar q opposite the pass between the rollers. Stops r on a feed-table d serve for side register of the printing-plate, 8 and subsequently of the sheet to be printed. After the printing-plate is registered the plunger h is withdrawn, the roller c raised to engage the plate which is then released from the studs p, and the cylinder b rotated by a handle f to cause an impression to be transferred to a rubber blanket e on the cylinder b. By a similar operation several impressions are obtained from the transferred impression on proof sheets, or other sheets, which are fed between the rollers b, c. The printing pressure can be varied by adjusting an eccentric pin u to which the springs j are secured and holding the pin in the required position by means of a peg w. Weights may replace the springs j.

Abstract: 347,277. Controlling induction motors. ELECTRIC MACHINERY MANUFACTURING CO., Minneapolis, Minnesota, U.S.A.-(Assignees of Early, R. N.; Minneapolis, Minnesota, U.S.A.) Jan. 25, 1930, No. 2686. [Class 35.] The primary windings of a squirrel-cage motor are formed of parallel-connected sections 5, 6, all used during running, but one set of which, in all or certain phases, is cut out by switches 7 during starting. The switches 7 may be controlled by a relay 13 shunted across an impedance 11 in the wound field circuit F, so that they are maintained open during the first part of the starting period. In one modification an external resistance or inductance is also used, this being short-circuited either before or after the switches 7 are closed. Another modification comprises the use of bridging switches for joining corresponding intermediate points on the two parallel windings. According to a further modification, condensers can be shunted across one of the windings. A higher impedance at starting is obtained by concentrating the windings on adjacent poles instead of winding them uniformly. Specifications 21005/03, 265,160, and 263,884, [all in Class 35, Dynamo-electric generators &c.], are referred to.

Filed: 1947-01-31
Abstract: 662,844. Automatic control systems. BENDIX AVIATION CORPORATION. Jan. 31, 1947 [Feb. 18, 1946], No. 3038/47. Class 38 (iv). An electrical control signal is produced by a normally balanced bridge which is rendered unbalanced by the change in temperature of a second bridge forming one of its arms and to which the initiating signal is applied. In a craft control system, as shown, Fig. 4, which is an improvement on that described in Specification 611,226, the deviation signal derived at 11 is applied through the amplifier 16 to the servomotor 42 of the control surface 10, and to stabilize the system at the correct datum, an additional signal is applied, with the feed-back signal, to the servomotor through the valve 82 and the time-delay, heat-responsive  bridges respectively composed of equal resistors 68, 69, 70, 71 and 73, 74, 75, 76. The heat responsive bridges, together with the resistors 60, 61 form a further normally balanced bridge to which is applied the followup signal and which unbalances in a sense dependent on the sense of the follow-up signal if the follow-up signal is persistant, to provide the additional automatic trim control signal. In a further embodiment, Fig. 5 (not shown), heating is prevented in a control system as in Fig. 4 by the application of the deviation signal to the time-delay bridge circuit, the output of which is applied, with the deviation and follow-up signals to the servomotor. Specifications 662,831 and 662,845, [Group XXXVI], are referred to.

Abstract: 1451686 Automatic control of speed MT BYER 23 Jan 1974 [24 Jan 1973 15 Oct 1973] 03083/74 Heading G3R [Also in Division B7] In a vehicle speed control system, if the vehicle overspeeds an accelerator pedal is moved to effect a vehicle speed reduction. In the embodiment, vehicle speed dependent signals from coil 80 pass via Schmitt trigger 83 to monostable multi-vibrator 89, that produces pulses at a frequency dependent upon the vehicle speed. A D.C. voltage, also proportional to vehicle speed, is derived from these pulses by amplifier 96, and compared at 101 with a desired speed reference. If the vehicle speed exceeds the reference, transistor 106 is switched on to energize a suction control valve in a piston cylinder arrangement see Fig. 2 (not shown), thus moving the vehicle accelerator pedal against pressure by the driver's foot until the vehicle speed falls below the reference. Potentiometers 113-115 set the speed reference, and are selected manually e.g. upon entering a speed restricted area, or automatically e.g. by detecting a fixed source of magnetic radiation using a pick-up on the vehicle.
