Title: Improvements in and connected with brake and accelerator control devices for use on motor road vehicles and the like
Filed: 1936-08-04
Abstract: 476,770. Controlling motor vehicles. WADE, C. Aug. 4, 1936, No. 21464. [Class 79 (v)] [Also in Group XXXIV] In a combined brake and accelerator control for motor vehicles, the brake pedal carries a laterally slidable abutment by which the accelerator can be controlled without moving the pedal, the arrangement being such however that the accelerator is returned to a reduced speed position when the pedal is depressed to apply the brakes. A plate 5 engageable by the edge of the foot is slidably mounted on the plate 2 of the brake pedal by a rod 4 passing through a lug 3 on the plate 2 which may also have guide slots 13 for projections 12 on the plate 5. With the pedal in the raised position the rod 4 engages a lever 9 pivoted at 10, inclined downwardly away from the pedal and connected by a link 11 to for example the throttle of an internal-combustion engine or the rheostat of an electric motor. When the pedal is depressed. the rod 4, if occupying a low or normal speed position, moves out of contact with the lever 9 so that the lever is returned by the spring 11a. If, however, it is desired to accelerate when taking off the brake, the driver can while easing the pressure on the pedal press the plate 5 laterally to a high speed position so that the speed will be increased proportionately to the upward movement of the pedal.

Title: Method of and means for verifying on the ground, the force conditions for the safe taking off of aeroplanes
IPC: B64F1/00
Filed: 1931-07-31
Abstract: 379,489. Dynamometers. TECALEMIT, Ltd., Great West Road, Brentford, Middlesex.-(Piquerez, E. ; 4, Avenue de 1a Pommeraie, St.-Cloud, Seine-et-Oise, France.) July 31, 1931, No. 21922. [Class 106 (ii).] For verifying on the ground the forces relating to the flying-off conditions of an aeroplane means are provided for measuring the ratio of the force driving the machine forward to the weight of the machine so that the latter is not allowed to start unless this relation is at least equal to a predetermined safe value. In the diagram the machine is supported by the landing chassis resting on a carriage 1 and the tail skid on a carriage 2 and secured by chocks 7, each carriage being mounted on four rollers running on like curved surfaces of increasing curvature in the direction of motion. On starting the propeller, the carriages ride up the inclines 4 until the reactions of the inclines balance the thrust of the propeller. The tangent of the angle Q then gives the relation between the horizontal thrust T and the total weight P of the machine. In the practical form of the apparatus each landing wheel and the tail skid rests on a small trolley adapted to run on curved inclines located in a pit so that the trolley platforms are approximately level with the ground. A scale may be provided on the edge of the pit to co-operate with a pointer on the trolley. For distant reading ropes attached to two trolleys are led to two spring drums in an instrument let into the ground the movement of the drums causing pointers to move over a scale. This instrument may be provided with printing means to print the value of the ratio on a card which is issued. In addition, a semaphore signal may be provided the arm of which when set stands up but when a catch connected to a trolley is released falls out of sight thus signalling to the pilot that the desired ratio has been reached.

Title: Improvements in or relating to enumeration of bodies in a state of irregular distribution in a medium
Inventor: COOKE-YARBOROUGH EDMUND HARRY

Abstract: 714,344. Particle counters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 18, 1952 [Sept. 19, 1951], No. 21937/51. Class 40 (3) In particle counting equipment in which the dstributed particles are scanned in a series of lines of constant length and separation a detector which may be photo-electric, produces an electrical pulse whenever the scan passes over a particle and operates a counter only if pulses which commence at a time later than a defined time in each scan are produced in successive scans. This renders the effective scanning width independent of the actual size of the particles. As shown, particles 2a to 2b &c. are scanned by a series of minor lines 4a, 4b &c. a number such minor line scans making up a major line scan 5a. The scanning is then repeated in major scans 5b and 5c. The part of each minor scan to the left of chain dotted line 3a is known as the guard zone, the part to the right as the counting zone. If a particle is to be counted it must produce pulses in at least successive minor scans in the counting zone but not produce two such pulses in the guard zone, secondly each particle must be followed by a vacant scan and thirdly the successive pulses must have an overlapping portion. Thus particle 2a is counted, 2b produces two pulses in the guard zone and is not counted, 2c is counted, 2d is not counted since it is not followed by a clear space but particles 2e 'and 2f are together counted as one particle, 2g, 2h and 2l are too small to be counted. Circuit arrangements. (Fig. 2). A flying spot line scan is produced by a scanner supplied from a sawtooth generator 12. The flying spot illuminates a specimen on a slide 13 through a microscope eyepiece and activates a photo-multiplier tube P.M.T. The tube output is monitored by a cathode ray tube 14 and fed to an amplitude discriminator 15. The output of the discriminator is applied simultaneously to a delay line 17 and a coincidence circuit 16. Thus the first pulse is de'ayed by a period equal to the duration of one minor scan so that the coincidence circuit gives an output to a register "flip-flop" only if the pulses are tested to see whether they are produced in the guard zone by a gate pulse generator 22 which feeds a coincidence circuit 21 also receiving the output of coincidence circuit 16. If there is coincidence between the two pulses a " cancel " flip-flop circuit 33 is triggered. The register is not operated until no pulse appears in the delay line. This is detected by diode 27 which provides a pulse to reset cancel "flip-flop" 23 and register "flip-flop" 19. If only the register flip-flop is reset, an output pulse is produced which is counted. If both "register" and "cancel" "flip-flop" act simultaneously the anti-coincidence circuit 30 does not pass a pulse to a scaler 31 and counter 32. Specification 674,265 is referred to.
