Title: An improved hand-operated letterpress printing press
IPC: B41F3/46
Filed: 1929-08-26
Abstract: 338,876. Aspinall, D. A. Aug. 26, 1929. Platen presses.-A hand-operated platen press of the kind described in Specification 297,885 is modified by causing the printing pressure to be applied to the pivoted platen 1 by means of an unequal arm lever 10 pivoted to a rod 8 carried by lugs 2 on the platen, the arm 9 of lever 10 being received by an inverted U-shaped member or presser-bar 12 secured to the bed of the machine. Pressure is applied to the outer end of the lever 10, and during the printing operation the under edge of the member 12 serves as a fulcrum. After printing the lever 10 is pulled upwards and the end 9 withdrawn from the member 12 and the platen 1 is raised about a pivot 7 and moved over to the dotted line position of Fig. 3 for delivery to the printed sheet and insertion of a new sheet. The printing type is mounted in a chase or secured direct to the bed 5, which is formed with side walls 4 bent at their upper ends to form runways 17 to guide the inking-roller 15 as it is traversed under the member 12 and over the type by means of bent arms 13 pivoted to the rod 8. The roller 15 also traverses an ink-table 16. The table 16 and the bed 4 and runways 17 may be pressed from a single sheet of sheet-metal, which is shaped so as to form also supporting feet 16<1> for the table 16, and the platen may also be formed of sheet-metal.

Title: Improved driving mechanism for auxiliary apparatuses of vehicles
IPC: F02C5/06
Filed: 1956-08-24
Abstract: 819,670. Motor vehicles; propelling vehicles. REGIE NATIONALE DES USINES RENAULT. Aug. 24, 1956 [Sept. 26, 1955], No. 25923/56. Classes 79(2) and 79(3) [Also in Groups XXIV, XXVI and XXVII] In a vehicle having a free piston gas generator feeding, simultaneously or not, a driving turbine for the road wheels and an auxiliary turbine, the mechanism driving auxiliary apparatuses is characterized in that its driving shaft is driven by one or other of two free wheels driven respectively by a movement originating in the output shaft of the driving turbine and by a movement originating from the auxiliary turbine fed by a pipe for delivering the exhaust gases of the generator to the atmosphere. The free piston gas generator 1 drives a main turbine 3 to propel the vehicle, or an auxiliary turbine 6 when turbine 3 is not in use and gas is passed to the atmosphere through valve 2 and pipe 5. Shaft 9, driven by one of the free wheels 8, 11 connected to the drive shafts of the turbines by drive transmitting means 7, 10, drives variable speed auxiliary apparatuses 12 and, through a change speed device 14 and shaft 13, constant speed auxiliary apparatuses 15, 16, 17, 18 and 21. The change speed device 14, which may be of the belt and extensible pulley type, is moved to the left or right by a piston 25 and flange 24 to lower the speed of rotation or raise it respectively. The piston 25 is acted upon on one side by fluid from a pump 27, driven by a shaft 9, and a spring 26, and on the other side by fluid pressure from generator 1. When the vehicle is stopped the pressure from the generator is at the minimum so the piston 25 and flange 24 are kept toward the left, the turbine 6 driving shaft 9; with the vehicle at maximum speed and maximum pressure from the generator the forces on piston 25 are balanced so it remains to the left; with the vehicle slowing down but still maximum pressure from generator, e.g. when vehicle approaches a hill, the pressure from the generator 1 is greater than that from the pump 27 and spring 26 combined so the piston 25 and flange 24 moves to the right to raise the speed of rotation. A constant ratio transmission 19 from shaft 13 drives, through a centrifugal clutch 20, a braking air compressor 21 which can be driven through clutch 22 by an electric motor 23 when the gas generator is idle. In Fig. 2, not shown, the pump 27 is replaced by a governor acting on a lever which acts on the piston.

Title: Improvements in electrical apparatus for the elimination of aperiodic disturbances
IPC: H04B1/12
Filed: 1924-10-31
Abstract: 237,547. Regnauld de Bellescize, H. J. J. M. de. July 22, 1924, [Convention date]. Addition to 226,784. Atmospherics and undesired signals, eliminating or limiting.-Signal currents with superposed perturbations are fed from an input circuit A, A Fig. 1, to a receiver R through two branch circuits. One branch C1, L1, L2, S1 transfers both desired and undesired 'frequencies alike to the grid circuit of the valve D. The other branch comprises means for blocking out the signal frequencies. but passes the undesired disturbances. The latter are then balanced against their counterparts in the first circuit, leaving the signal currents alone to influence, the grid of the triode D and reappear in the receiver R. The passage of the signal frequencies is prevented by a polarized electromagnet in the plate circuit of the valve D1, the armature F1 of which is fitted with a rubbing contact H, G which imparts sufficient mechanical friction to prevent the armature from responding to the signal frequencies although it is ineffective to stop thetransfer of aperiodic disturbances of relatively large amplitude. The same principle underlies the arrangement shown in Fig. 2. The complex current is fed to an artificial line C, L from which tappings at P1 and P3, separated by an effective signal wave-length, are taken to the grid and filament of the valve X. The signals proper therefore do not affect the output from that valve apart from a slight shock corresponding to impact and end effects, which are eliminated by the frictional action of the parts G, H on the armature F1. The disturbances, on the other hand, gives rise to two impulses, separated by one signal wave length, which are opposed in their action on the armature F@, so as to leave only a small residual effect. This, in turn is balanced out across the grid and filament of the valve Y by means of tapping P2, which transfers the signal frequency in full, and that fraction of the disturbance (regulated in intensity by the tapping Q2) necessary to counterbalance the residual effect from the armature F1. The signal alone therefore reappears in the plate circuit of the valve Y.

Title: Improvements in electric control apparatus, particularly for effecting a given operation of an electromagnetic device upon a movable element reaching a given position
IPC: H02P5/46
Filed: 1946-08-30
Abstract: 643,211. Operating clutches. IGRANIC ELECTRIC CO., Ltd. Aug. 30, 1946, No. 26138. Convention date, Aug. 31, 1945. [Class 80(ii)] [Also in Groups XXII, XXX, XXXV, XXXVII and XL(c)] An electromagnetically operated clutch controlled by a valve 17 may be used to control the stopping of a conveyer 10. The voltage normally induced in winding 20d is equal to and of opposite polarity to that induced in winding 19b so that no voltage is impressed upon a condenser 18, the valve 17 thus being conductive to operate a relay 25 to close contacts 25b. Operation of a push button 28 then operates relay 27 through contacts 25b to operate an electromagnetic clutch to clutch the conveyer to a continuously rotating driving motor (instead of the relay 27 closing a circuit for a motor 13 as shown). When a core 20e moves into the air gap of the transformer 20 the voltage-induced in winding 20d is reduced so that a voltage is now impressed upon the condenser 18, via a suitably poled rectifier 21, to drive the control electrode 17c negative to make the valve 17 non- conductive causing relays 25, 27 to drop out thus returning the electromagnetic clutch to its normal condition to bring the conveyer to rest at a substantially predetermined position. The charge acquired by the condenser 18 prevents the re-starting of the conveyer until the charge has been dissipated. An electromagnetic brake may be used to assist the stopping of the conveyer.
