Abstract: 1296915 Toy vehicle propulsion unit LOUIS MARX & CO Ltd 22 May 1970 [28 Nov 1969 24983/70 Heading A6S A propoulsion unit for propelling a toy vehicle round a trackway system comprises a guideway 17 for receiving a trackway portion 11, a spring-loaded propulsion member 21 which is provided with a driving head 24, a cocking handle 33 and a cocking finger 25. A trigger 27 is provided which projects into the path of the on-coming vehicle 14, and has at its other end a detent 29 which is located against a detent-ledge 26 on the propulsion member 21 so as to retain the propulsion member in the loaded position against the pull of spring 23. The vehicle striking the projecting arm of trigger 27 causes it to rotate out of the path of the vehicle and releases the propulsion member 21 which is rotated rapidly under the influence of spring 23 causing the driving head 24 to strike the rear of the vehicle 14 and impart a driving force thereto. The propulsion member is then re-cocked manually by means of handle 33. On doing so the cocking finger 25 contacts the arm of trigger 27 causing it to be rotated into the path of the on-coming vehicle again and causing detent 29 to be located against detent ledge 26. A counter for counting the number of passes of the propulsion unit the vehicle makes is provided and comprises a cover plate 42 attached to the base having a viewing aperture 43 and a post extending downwards on which are mounted two discs 45 and 48, disc 45 being marked with numbers and acting as the counter. The underside of the cover plate and the discs 45 and 48 have co-operating ratchets 47 and 49 so that the disc 45 can only be rotated in one direction and the disc 48 when rotated in that direction causes disc 45 to be rotated, and when rotated in the other direction rotates relative to disc 48. The rachets are maintained in contact by means of spring 52 which also serves to bias disc 48 in a clockwise direction. The counting unit is operated by propulsion unit 21 contacting and displacing an arm 58 attached to disc 48. When the propulsion member is released the disc 48 rotates under the action of spring 52 until it strikes a stop 57 and rotates disc 45 with it, advancing the counter one unit.

Title: Ultrasonic measuring apparatus
IPC: G01B17/00
Filed: 1970-02-09
Abstract: 1323079 Ultrasonic length measurement BRITISH STEEL CORP 19 April 1971 [9 Feb 1970] 6026/70 Heading H4D The length of a metal billet or other elongated section is measured by transmitting an ultrasonic pulse into the section and measuring the time for the pulse to be reflected back from the far end by a counter which gives a direct reading of the length, the counter only being stoppable during a selected period in which the reflection is expected. The section, which may be in a stack and accessible only at one end, is coupled to transducer 2 by a film of grease. Ultrasonic generator 6 is pulsed by low frequency source 8 e.g. at 2 c./s. The reflected pulse is received by 2 and the resulting signal is passed to amplifier 10, rectified by 12 and passed to further amplifier 14. The signal from source 8 is delayed by monostables 18, 20 and fed to gate 16, the delay being adjusted so that gate 16 is only operable during a period when the reflected pulse is expected, amplifier 14 also feeding gate 16. Source 8 also controls monostable 26 which opens gate 22, the gate controlling gate 30 via inverter 28. Gate 22, when open, opens gate 30 allowing access to counter 34, supplied with pulses from clock 32. The clock frequency is adjusted so that for a given material the count indicated on readout tubes 40 is a direct indication of the length. Reception of the reflected pulse fires monostable 24 and closes gate 22 stopping the count. Further monostables 42, 44 fed by source 8 reset the counter after a time sufficient for the count to be read.

Filed: 1970-10-13
Abstract: 1327112 Dispensing measured quantities of granular material G W ARMSTRONG 13 Oct 1970 48687/70 Heading B8N A valve for dispensing measured quantities of granular material comprises a housing 12 having an inlet 13 and an outlet 14, blades 30, 40 each carried by a respective pair of pivoted levers 32, 42 for movement between a closed or flow blocking position and an open or flow permitting position, and means including double acting hydraulic or pneumatic rams 50 and springs 60 for effecting movement of the blades. When the valve is conditioned as in Fig. 3, extension of the rams will apply, simultaneously, forces on the pairs of levers, but, due to action of the springs 60, the blade 40 will be moved to its closed position prior to the blade 30 being moved to its open position. Thus material will flow into the valve. When the blade 30 reaches its open position a lever (128) (Fig. 2, not shown) on one of the levers 32 actuates a valve (125a) to effect changeover of the pressure fluid supply to the rams so that the rams are retracted to first effect closure of the blade 30 and then to effect opening of the blade 40. Thus material is dispensed via the outlet 14. When the blade 40 reaches its open position arm 42a of one of the levers 42 actuates a valve 125b to again effect changeover of the fluid supply to the rams so that the latter are again extended. Exhaust of fluid from the rams is via a variable outlet (132) (Fig. 11, not shown). Thus the deviation of extension and retraction of the rams can be varied. Openings 35, 45 through which the blades 30. 40 extend are each provided with sealing strips 90, 96, 100 and 102, and the spaces between the side edges of the blades and the side walls of the housing are sealed by sealing strips 72, 82 secured to the side walls.
