Title: Improvements relating to priming internal combustion engines with lubricating oil
IPC: F01M5/00
Filed: 1941-02-17
Abstract: 547,224. Lubricating. HALLEWELL, G., and BLACKSTONE & CO., Ltd. Feb. 17, 1941, No. 2167. [Class 12 (iii)] An internal-combustion engine is primed with lubricating oil by compressed air from the starting- air receiver, the pressure of the air forcing the oil from its container to the engine parts. Oil from the engine sump 2 flows through a partial-non-return valve 12 to the container I which is connected by pipe 8 to the pipe 9 leading from the receiver 10 to the engine. On starting, the air forces the oil from container 1 through pipe 4 and reducing valve 13 and thence through either pipe 7 and the piston lubricating system or non-return valve 5 and pipes 6 and the filter box and bearings in the main lubricating system. Valve 12 reduces the area of the pipe opening when the pressure in the container 1 is greater than that in the sump 2. The container 1 may have a non-return outlet valve 14.

Incrustation, preventing.-The form characteristic of a pulsating direct or an alternating electric current applied to metallic surfaces for preventing incrustation is altered or distorted by being subjected to the influence of one or more reactance devices, e.g. induction coils or condensers used alone or in conjunction with interrupter or vibrating devices. The secondary of a transformer 1 connected across a sine wave alternating current source of 110- 250 volts is connected with a vibrator 2, an induction coil 3, a reactance coil 4 and a condenser 5 in addition to a boiler 6 to be protected against incrustations. With the voltage reduced' to about 8 across the secondary of the transformer, coils 3, 4 being of 300 and 0.8 ohms. resistance respectively, and the condenser having a capacity of about 2 microfarads, the apparatus provides about 25 milliamperes through the secondary circuit applied to the boiler. The interrupter may be dispensed with in the case of alternating currents of frequencies above 40' cycles per second.

Abstract: 565,602. Supply and control systems for resistance welding. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 19, 1943, No. 2794. Convention date, Feb. 28, 1942. [Class 38 (iv)] Thermionic control.-A welding or other load circuit is supplied with impulses of energy derived from an A.C. circuit 6 through a capacitance 5 which is discharged in alternate senses through the primary winding of a transformer 2 by pairs of controlled valves, such as ignitrons 22, 25 and 23, 24, the conductivities of the pairs being selectively controlled. A pair of reversely connected valves, such as ignitrons 101, 102, are also connected across the primary winding to prevent substantial reversal of the polarity of the capacitance at the end of each impulse. Each of the aforesaid valves may be ignited by a control valve in series with each ignition electrode and timing means associated with a valve 86 may be arranged to produce a periodic voltage to control the periodicity of the energization of the load circuit, other timing means 41 controlling the alternate selective operation of the valve pairs 22, 25 and 23, 24. The conductivity of the valves 102, 103 may be controlled by a transformer 106 in parallel with the transformer 2 having oppositely poled secondary windings each connected to the grid of a control valve 104, 105 through a circuit comprising a capacitance such as 115 and a resistance 114 to produce a voltage tending to maintain the control valves conductive selectively in response to the direction of current flow through the primary winding of transformer 2 and into the region in which the polarity of the capacitance 5 tends to reverse. The remaining supply and control arrangements shown in the Figure are described in Specification 563,531 to which the present Specification refers.

Title: Improvements in driving mechanism for toys and the like
IPC: A63H29/06
Filed: 1920-01-30
Abstract: 162,101. Mitchell, F. A. Jan. 30, 1920. Boats; mechanical toys.-Driving-mechanism for locomotive toys, toy boats, or stationary mechanical toys consists of a spring which is connected to a rack that gears with the mechanism of the toy, the spring being tensioned by pulling or pushing a member projecting from the toy. The spring S, Fig. 2, is enclosed in a stamping R bent to form a double-edged rack, and is anchored at one end S<1> to the rack and at the other end S<2> to the frame of the toy. The tensioning-member consists of a wire T passing through a hole R<1> in the rack and provided at one end with an enlargement T<1>, the other end being passed through the frame and formed into a loop T<2>. The rack is in gear with a pinion A<1> forming part of a train connected to the wheels D of the toy, the axle of the pinion being journaled in a slot F<1> in the frame. In use, the loop T<2> is pulled to tension the spring, the slotted bearing F<1> allowing the pinion A<1> to be turned by the rack without rotating the wheels D. The wire is then pushed back into the frame, and the pull of the spring draws the wheels into gear again and drives the toy when the wheel D is released. The tensioning member may consist of a rod fastened at right angles to the rack and projecting from the sides of the toy. In this case, the rod may travel over a scale indicating the distance or the time the toy will run when the rod is pulled to any particular point. The rack may be arranged to compress the spring instead of stretching it, and the toy may be fitted with a brake which prevents the wheels from being rotated when the toy is lifted from the ground. A second spring may also be fitted to draw the member T back into the frame after the driving-spring S has been tensioned. In the toy crane shown in Fig. 6, a segmental rack R rotating on a pivot R<3> is connected by a tensioning member T with the top of a pivoted jib J. Thus a weight attached to the jib will rotate the rack on its pivot and stretch the spring S, and when released, the spring will contract, raise the jib, and propel the toy. The rack may consist of a perforated strip of metal or may be flexible or similar to a chain. The spring S may be V- shaped, as shown in Fig. 8, and be compressed by a rack R, the tensioning member T also consisting of a rack in gear with a. pinion L secured to the pinion a. The pinion L may be of greater diameter than the pinion and may be connected to it through a ratchet gearing, so that the spring can be tensioned by repeated pushing or pulling of the member T. The mechanism mav be used to propel toy 'boats or to drive stationary mechanical toys. Reversing-gear and a fan or air retarder to control the speed may be fitted to the toy.
