Title: Improvements in obtaining fuel economy in internal combustion engines
IPC: F02D29/00
Filed: 1941-11-10
Abstract: 553,210. Fluid-pressure servomotor-control systems. VILLIERS, C. P. R. DE. Nov. 10, 1941, No. 14457. [Class 135] An internal combustion engine drives a load through a continuously variable speed gear, the gear changing means being responsive to the conjoint effect of engine speed and another function of engine power, the arrangement comprising a cam which transmits the speed effect and varies its magnitude with respect to the other effect according to a non-linear law representing the relationship of the effects which conduces to fuel economy. In the form shown in Fig. 1 comprising an engine 2 and a continuously variable hydraulic transmission, the speed ratio of which is variable by a lever 10, the lever is operated by a servomotor 12 supplied from the pipe 8 or 9 of the hydraulic transmission under the control of a valve 17 actuated by a floating lever 34. The position of the lever 34 during forward drive is determined by the pressure difference between the pipes 8, 9 representing the torque effect and acting through a plunger 26, and by the speed governor 37 acting through a cam 40. Movement of the lever 11 of the pump of the hydraulic transmission into neutral or reverse drive position sets a stop 48 to prevent the lever 34 from moving out of its low-gear position. The shape of the edge of the cam 40 is determined from a graph obtained experimentally according to prescribed directions. In another form, the pressure drop due to throttling, positions a piston 60, Fig. 4, working in a cylinder 59, the lefthand end of which is open to the atmosphere or connected by a pipe 64 to the high pressure side of the throttle valve 54, and the stop 48 is replaced by a cock 72 which puts the pipe 62 to atmosphere when the lever 11 is in neutral or reverse position. The throttle valve is actuated from a pedal 3 or governor 37 through a floating lever 56. In the form shown in Fig. 6, the lever 34 is acted on by the governor 37 and the movement of the engine controller, a collapsible link 76 including a weak spring 79 being interposed in the connections from the governor.

Title: Improvements in directive wireless systems
IPC: H01Q25/00
Filed: 1940-09-24
Abstract: 576,941. Directive wireless signalling; radiolocation. DOWSETT, H. M. Sept. 24, 1940, No. 14509. [Class 40 (v)] Apparatus for producing an electromagnetic beam having two concentric parts, comprises a single dipole and separate reflector systems so constructed that the complete beam retains the individual divergent character of the two concentric parts for the whole of its length. The dipole AOB is arranged at one focus of a double ellipsoidal reflector CD, part of the radiation being focused at S by the reflector C, and the other part being focused by the reflector D at the point P from which it passes to a further ellipsoidal reflector E which focuses it at the same point S, thus producing two concentric divergent beams. In a modified arrangement, the reflector E is paraboloidal, producing a hollow cylindrical beam within the divergent beam. The dipole is rigidly mounted on the reflector which is mounted on trunnions so that it can be moved like a searchlight. For receiving the reflected rays, a pair of crossed dipoles R1, R2, Fig. 2, and associated reflector wires may be mounted on the reflector axis behind or in front of the transmitting dipole where there is no radiation.

Title: Monitor apparatus for altering the sequencing speed of a data  processor
IPC: G06F1/08
Filed: 1974-04-02
Abstract: 1450324 Data processing system BURROUGHS CORP 2 April 1974 14522/74 Heading G4A A data processing system having a master clock pulse generator includes a monitoring device to enable the operating speed of the processing system to be varied without varying the frequency at which the master clock generator operates, the device including an input receiving the master clock pulses, oscillator means producing pulses at one or more frequencies less than that of the master clock generator, and a settable speed selector determining whether the processing system is controlled by the master clock generator or the oscillator means. The arrangement allows the system to be sequenced at a lower speed, e.g. for minitoring purposes, without affecting the master clock whose continued operation may be necessary, e.g. to maintain an associated memory operative. As described two local oscillators of low and medium speeds, together with a manually operable single shot device are provided. A mode selector is also provided so that for each pulse from a selected one of the oscillators or the single shot a single pulse or a series of pulses (at the master clock frequency) are emitted. The multiple pulse mode setting is used when each instruction consists of several bytes each of which is sequenced by a respective pulse. A stop detector is provided to stop the system when a predetermined state exists within the system, a stop being necessary where sequencing is to be performed manually using the single shot. A logic circuit and associated state diagram are given to provide the necessary control.

Title: Improvements relating to methods of suppressing arcing at contacts breaking an inductive circuit
IPC: H01H9/54
Filed: 1949-05-31
Abstract: 663,898. Sparking preventing in switches. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and WALKER, A. H. B. May 2, 1950. [May 31, 1949] No. 14538/49. Class 38 (v). Arcing at a switch 5 controlling an inductivecircuit 1 is suppressed by means of a rectifier 8 subjected to a reverse biassing voltage and connected so that surge energy due to the breaking of the circuit is fed through the rectifier to the biassing source and is absorbed thereby whenever the surge voltage exceeds a predetermined value. In Fig. 1, the source 6, 7 supplying the circuit 1 is also the biassing source. On opening the switch 5, a voltage is induced in the winding or tapped portion 2, 3, which, when it exceeds the supply voltage, sends current through the rectifier 8 and source 6, 7. In Fig. 4, a separate biassing source 10 is used and connected in series with the rectifier across part of the inductance 1. In Fig. 5, the biassing source is a condenser 12. This arrangement is for contacts which operate a number of times in quick succession, which causes a voltage to be built up in the condenser. In Fig. 6, which is suitable for A.C. or reversible D.C. the biassing source is a battery 10 and is connected to a full wave rectifier 14 connected to a coil 13 coupled to the inductance 1.

Crimped stereoregular polypropylene conju gate filaments in which the two components are disposed in side-by-side relationship and are bonded together along the length of the filament are produced by simultaneously melt extruding through the or each orifice of a spinneret into a gaseous cooling zone two polypropylene components one of which (component X) has an intrinsic viscosity [#], (measured in tetralin at 135‹ C.) of 1.4 to 3.0 and a birefringence of 9 x 10<SP>-3</SP> to 27 x 10<SP>-3</SP> and the other of which (component Y) has an intrinsic viscosity of 0.8 to 3.0 and a bi-refringence within a range corresponding to the area, a, b, c, d, e in Fig. 1, which is determined in accordance with the bi-refringence of component X (when the latter is in the form of an undrawn non-composite filament), drawing the resulting composite filaments at a temperature above 80‹ C. and then relaxing the drawn filaments so that they spontaneously develop crimps. Component X may have a bi-refringence of 14 x 10<SP>-3</SP> to 27 x 10<SP>-3</SP> and component Y may have a bi-refringence within a range corresponding to the area c, d, e, f, g, in Fig. 1. The drawn filaments may be subjected to heat treatment below 140‹ C. under tension sufficient to prevent the development of crimps and then to relaxation to develop crimps. After relaxing the drawn filaments to develop crimps, they may thereafter be subjected to tension sufficient to prevent the development of crimps and then further relaxed to develop crimps. The drawn filaments may be relaxed to develop crimps, then drawn at a draw ratio lower than that used in the first drawing step and finally again relaxed to redevelop crimps. The drawing of the undrawn filaments may be effected at a draw ratio of 0.4 to 0.9 time the maximum draw ratio. The undrawn filaments may be drawn at 100 to 140‹ C. The tension treatment and/or the redrawing step may be effected at a temperature within the range of room temperature to 130‹ C.
