Title: Improvements relating to means for regulating motor vehicle engines
IPC: F02D29/00
Filed: 1955-11-02
Abstract: 783,036. Regulating. DAIMLER-BENZ AKT.-GES. Nov. 2, 1955 [Nov. 2, 1954], No. 31393/55. Class 7(6) [Also in Groups XXIX and XXXI] The maximum power output of a motor vehicle engine is reduced in one or more of the lowest gears, as compared with the maximum output in at least one higher gear. In. Fig. 1 the load of the spring 17 of a governor 16 controlling a fuel injection pump control rod 11 is reduced when the gear lever 25 is moved into first gear so that the maximum speed in first gear is limited to a value below the normal maximum. The force of spring 17 is controlled by a sleeve 18 actuated by a servo piston 28 controlled by a valve 31 which is connected by a rod 22 to a lever 23 carrying an abutment 24 positioned in the first gear slot I. When the gear lever 25 is in neutral, reverse, or gears II... IV, the valve 31 is in the position shown in which the piston 28 is forced to the left and the load of spring 17 is at its maximum, corresponding to the maximum permissible engine speed. When the gear lever 25 is in first gear I, the lever 23 is actuated to move valve 31 to the left whereby pressure fluid is supplied through passage 40 to move piston 28 to the right to reduce the load of spring 17 and set the governor for a lower maximum speed. A second lever 49 connected to an abutment 53 in the fifth gear slot V and co-operating with the end of the rod 22 may be provided so that the maximum speed is also reduced in top gear, a hand control lever 51 being provided to move the lever 50 out of contact with the rod 22 when it is desired to eliminate the maximum speed reduction in top gear. A valve 43 in the servomotor circuit may also be moved to the right by a lever 48 to eliminate the maximum speed reduction in all gears when desired. In a modification the piston 28 is arranged to be set in three different positions. a first position corresponding to the maximum permissible speed, a second position corresponding to a reduced maximum speed when the gear lever is in the first or fourth gear position and a third position corresponding to a still further reduced maximum speed when the gear lever is in top gear. In Fig. 4 the maximum opening of a throttle valve 70 actuated by a pedal 72 is reduced in first, fourth, and fifth gears bv stop sleeves 74, 75 which cooperate with an abutment 73 on the throttle valve operating rod and are actuated from the gear lever 80 by levers 76, 81. The stop sleeve 75 is also controlled by a centrifugal governor 84. Specification 759,112 is referred to. Reference has been directed by the Comptroller to Specification 691,973 [Group XXIX]

Title: Improvements relating to time base circuits
IPC: H01J35/20
Filed: 1947-11-27
Abstract: 645,145. Sawtooth generating circuits. HARDIE, A. M., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Nov. 27, 1947, No. 31425. [Class 40 (vi)] In a sawtooth generator the rise or fall of voltage or current is periodically arrested during each sweep period so that the sawtooth wave has a stepped sweep portion. Fig. 1 shows a sawtooth generator in which the suppressor grid of valve V1 is normally biassed so that the valve only conducts when a positive going pulse is applied to terminal 2. When valve V1 is rendered conducting capacitor C1 charges linearly through the valve until a negative-going pulse is applied at terminal 1 when valve V1 is cut-off and the voltage at point A remains constant. When the pulse terminates, capacitor C1 again continues to charge and the process is repeated until at a point depending on the setting of potentiometer P1 the gas-filled valve V2 conducts and discharges capacitor C1 and the cycle is repeated. The voltage at point A thus follows a sawtooth waveform with a stepped edge as shown in Fig. 2b. If the pulse applied to terminal 2 is of equal duration and in phase with the sawtooth waveform, the truncated sawtooth waveform shown in Fig. 2d is generated. The diodes V3 and V4 act as D.C. restorers and resistor R4 may be adjusted to linearise the sweep.

Abstract: 505,774. Endless - track vehicles. OESTERREICHISCHE SAURER-WERKE AKT.-GES., WIEN. Nov. 16,1937, No: 31478. Convention date, Nov. 25, 1936. [Class 79 (i)] In a vehicle adapted to run either on wheels or on endless tracks, the road wheels being raised and lowered relatively to the tracks to convert the vehicle from a wheeled vehicle to a track vehicle and vice versa, the steering wheels when being raised are simultaneously moved laterally nearer to the endless track so as to reduce the overall width of the vehicle when running on the tracks, the steering wheels always remaining outside the limiting plane of the tracks. In the construction shown the vehicle can run either on endless tracks 10 or on driving wheels 4 and steering wheels 2, the wheels being connected to the chassis frame 1 by the linkages shown in Figs. 2,3, and 6 so that they can be raised and lowered. The driving wheels 4 are mounted on an axle 6 which is raised and lowered by the rotation of shafts s having arms 45 connected by links 47 to brackets 48 on the axle. The steering wheels 2 are mounted on steering swivels pivoted to members 37 pivoted to arms 35 on the shafts s and also pivoted to parallel links 39 pivoted on the frame 1. Thus when the shafts s are rotated to raise the steering wheels from the position shown in Fig. 3 to that shown in Fig. 2 these wheels are also moved laterally to reduce the width of the vehicle. The shafts s are held in either set position by sleeves 75 splined thereto these sleeves being rotated, when desired, by means of cranks 59, 61 thereon operated from the gearbox 22<1> through cranks 55 and rods 60. The shafts s act as torsion springs to control the suspension links for the front and rear wheels, since the inner ends of the shafts are held by the sleeves 75. The tracks pass over driving pulleys 11, idlers 12 and 13, and load rollers 14 ... 18, the pulleys 11 being driven by the engine 22 through the gear-box 22<1> and a shaft 20.

Abstract: Modified polytetrafluoroethylene fine powders, a major proportion of the particles of which are submicroscopic bola-shaped particles, having an infra-red amorphous index of less than 0.15 and a negative 83/17 methanol-water wettability, may be prepared by forming a slurry of a polytetrafluoroethylene fine powder, having generally spherical particles and an infra-red amorphous index of less than 0.15, in a liquid medium, subjecting the slurry to the action of a high-speed blade cutter and separating the product.  The preferred medium is water.  A fine powder is defined as one having a total surface area of at least 9 square metres per gram as measured by nitrogen adsorption.  The infra-red amorphous index is defined as the ratio of the net absorbances at wave lengths of 12.8 and 4.25 microns.  The powders are said to have a negative wettability when they float and do not darken on shaking with the 83/17 methanol-water mixture. Pigments and fillers may be incorporated.  The powders may be calendered into films and sheets which may be sintered to give non-porous products.  The powders may also be extruded, or mixed with lubricants, e.g. naphtha, and optionally lubricant viscosifiers, e.g. polyisobutylene, and moulded to give preforms which yield flawless products on sintering.  The powders may be used to form electrical terminal blocks; tapes, sheets and films for electrical insulation and anti-fouling sheathing for boat hulls.
