In an I.C. engine, additional air or crankcase gases or any gas containing oxygen is introduced into the induction pipe 16 downstream of the engine throttle valve (not shown) through orifices 21, inclined baffles 20 promoting mixing of the added gas with the fuel-air charge. A valve 36, regulating the quantity added, is actuated by a cam 40 attached to the throttle spindle 41 so that at small throttle openings (the position shown) a small quantity of additional gas flows through a delivery duct 31, a duct 32 being blocked, and for progressively larger throttle openings the quantity first increases sharply as duct 32 is opened, then decreases uniformly as a tapered portion 36c of the valve gradually occludes duct 32 and finally drops to zero at full throttle opening when valve portion 36b blocks both ducts 31 and 32. A bifurcated pipe may extend to the centre of the manifold 16 to provide two further inclined outlets for the additional gas, Fig. 7 (not shown). In a modification, Fig. 9 (not shown), the cam 40 is replaced by a linkage between the throttle and the valve, the latter having a conical end and being axially adjustable in the additional gas delivery conduit. In an engine having two parallel inlet ducts, Fig. 14 (not shown), the supply of additional gas to each is controlled by one and the same conically ended valve.

Abstract: 922,311. Dental engines. SIEMENSREININGER-WERKE A.G. Nov. 25, 1960 [Dec. 5, 1959], No. 40690/60. Class 81 (2). In a dental unit the controls for speed, direction and starting of a drill motor are arranged separately. Thus, in one form, a control panel 7 having a number of push-buttons for determining the speed of the motor, is detachably mounted on the head rest while a foot switch 8 has two separate pedals providing respectively separate on-off switches for the two directions of rotation. The latter (see Fig. 4, not shown) incorporates a number of micro-switches associated with the control circuits and actuated selectively by the two pedals. Thus, in Fig. 6, switches 40, 41 are closed by one pedal and switches 42, 43, 44 are closed by the other. Power is applied to the input 65 and closure of switch 40 energizes relay 55, through rectifier 53, with consequent energization of relay 56, the contact 67 of which, in conjunction with the second contact 66, completes a circuit through the motor field winding 59 and armature 60. Resistance 60 is connected in parallel with the armature 60 so that the closure of pushbuttons 12 ... 17 may determine the magnitude of this shunt and consequently the speed of the motor. The second pedal causes contacts 42, 43, 44 to be closed and, of these, the first merely replaces contact 40 for the purpose of switching on the motor, while 43 and 44 reverse the connections of the armature so that the running direction is reversed. Electromagnetically operated valves 63, 46 are energized by changeover contacts 62, actuated by the support mounting of an airdriven turbine drill. These valves control the air and water supplies respectively to this drill while the contacts 62 simultaneously interrupt the supply circuit to the motor control relay 55.

Abstract: 953,517. Transistor pulse circuits. THOMPSON RAMO WOOLDRIDGE Inc. Oct. 30, 1962, No. 41033/62. Heading H3T. [Also in Division G4] In a shift register, each stage consists of a delay circuit including first and second capacitors and corresponding transistors utilized to permit or prevent the capacitors being charged by first and second clock pulses applied alternately to the two transistor-capacitor circuits. Fig. 1 shows an N-stage shift register whose final output may be connected to the input to provide a recirculatory register. Each stage, such as stage 1, includes an NPN transistor 12 and associated capacitor 13 and a PNP transistor 18 and associated capacitor 21. " False " or " true " inputs are applied as potentials of 0 volts or - 10 volts, respectively to the input 10, and clock pulse trains A, B, Fig. 2, are applied to resistors 15, 22. In operation assuring a - 10 volts " true " input, transistor 12 cannot be turned on so that when an A clock pulse occurs, it will charge the capacitor 13 positively, thereby applying a positive potential to the base of the transistor 18 which is thereby prevented from being turned on by the next B pulse which is therefore effective to charge the capacitor 21 negatively to produce a negative, " true " output at the output terminal 25. If a 0 volt " false " input is applied to the terminal 10, the transistors 12, 18 conduct when the pulses A, B occur and the condensers 13, 21 are not charged, so that a " false " output is produced at 25. Clock pulse trains C, D are applied to diodes 17, 24 and are effective to discharge the capacitors 13, 21 to ensure that the successive data items in the register are separated. Outputs may be taken from each shift register stage if required.
