IPC: G01P1/04
Filed: 1928-11-14
Abstract: 300,585. Morell, W. Nov. 15, 1927, [Convention date]. Speer-indicator transmission mechanism.- Relates to hand tachometers having several ranges of measurement which can be brought into use as desired and consists in employing change-speed gearing in which a pinion and several lay shafts carrying wheels in constant mesh therewith are arranged eccentrically in relation to a driving pinion. The constituent members of the tachometer proper are mounted on a framework 3 which carries the lay shafts 5, 6, 7 of the change-speed gear. A pinion 1 is mounted on the main shaft 4 of the tachometer while the change speed gear comprises three sets 8, 13; 9, 14; and 10, 15 mounted on shafts 5, 6, 7. The wheels 8, 9, 10 are disposed on one plane and always in mesh with the pinion 1. The wheels 13. 14, 15 are also disposed in one plane. The frame 3 is attached to the casing. The driving shaft and pinion 2 are mounted eccentrically in a cover 11 enclosing the frame, the cover being adapted to rotate about the axis of the tachometer so that the pinion 2 will mesh successively with the wheels 13, 14, 15. The main shaft 4 and the driving shaft 16 may be stationary, and the change wheels mounted on internally guided plates, and brought into mesh by being turned from the outside by a lever.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/06
Filed: 1948-12-30
Abstract: 668,543. Hydro-pneumatic s h o c k - a b - sorbers. ELECTRO-HYDRAULICS, Ltd., and JECIES, S. Dec. 15, 1949 [Dec. 30, 1948], No. 33553/48. Class 108(iii) A shock-absorber comprises two telescopic cylinders 1, 4, Fig. 2, in which are formed two main chambers A, B, filled with damping liquid and in mutual communication, and two springs C, D, of different characteristics, each separated from the liquid by at least one floating piston so that on telescoping of the cylinders under load, energy is absorbed by the damping liquid, and stored by compression of at least one of the springs C, over the whole stroke of the shockabsorber, the second spring D being compressed only if the load exceeds a predetermined amount. The spring D is formed by compressed air acting on a floating piston 11, movement of which is limited by an annular stop 16. Liquid communicates through damping orifices 6 with the space B. The spring C is formed by compressed air which acts on a further floating piston 8. An additional port 17 in the head 5 connects the space A with the annular space E between the cylinders 1, 4. In a modification, Fig. 1 (not shown), there is no port 17 and the annular stop 16 is replaced by a diaphram having apertures, which may be valved, to damp rebound movement of the shock-absorber. The ports 6 may also be valved to damp rebound. In operation, on compression, liquid damping occurs through the ports 6, and the piston 8 is driven downwards against the air spring C. When a predetermined pressure is attained in chamber A, the piston 11 is also deflected. In Fig. 3, the piston 11 and spring D are within the lower end of the cylinder 4, and the spring C and piston 8 within a tube 19 rigid with the cylinder head 2. Movement of the piston 11 is limited by a diaphragm 25 having damping apertures 26 which may be valved. The outer end of the tube 19 carries a counter piston 20 slidable within the cylinder 4. In operation, on compression, liquid pressure in chamber A (which builds up, due to damping caused by flow to space B) acts on piston 8, and at a predetermined pressure piston 11 is also' deflected. In a modified arrangement of the spring D, Fig. 4, a further floating piston 32 is provided, movement of both pistons 11 and 32 being limited by respective annular stops 31, 33. Inflation orifices are provided at 24, 30 for the respective compressed air springs D2, D1 formed by the pistons 32, 11. The compressed air springs C, D may be replaced by deformable solids, e.g., coil and rubber springs. and each may comprise a series of springs having stepped loadings. The Specification includes curves, Fig. 5 (not shown), indicating the relative performance of conventional shock-absorbers and those according to the invention. The invention is applicable to the nose wheel of aircraft tricycle undercarriages.

Abstract: 955,483. Multiplex radio signalling. CESKOSLOVENSKA AKADEMIE VED. Sept. 30, 1960 [Sept. 30, 1959], No. 33565/60. Drawings to Specification. Heading H4L. Relates to a system for the generation of the carrier frequencies of at least two television transmitters sharing a channel, wherein the respective carrier frequencies differ only by a small value (the offset value) from the nominal frequency of the channel. The offset value is made a multiple of the frame frequency and it is stated that this reduces mutual interference. A block diagram of a television transmitter showing the frequency changing &c. to produce a specified carrier and offset frequency is included. In the example given the offset frequency is approximately <SP>2</SP>/ 3  of the line frequency and is derived from the frame frequency which itself is controlled by the 50 c/s. mains frequency. The frame synchronization means is common to all the transmitters.

Title: Apparatus for generating sample pulses in a telephone image transmission system
IPC: H04N7/12
Filed: 1974-07-31
Abstract: 1475352 Television RCA CORPORATION 31 July 1974 [10 Aug 1973] 33690/74 Heading H4F In a television image transmission system of the type described in Specification 1,393,674 in which a video signal frame is stored and then sampled column-by-column and row-by-row at such a rate that transmission of the video signal samples over an audio link is possible, the sampling is effected by gating pulses derived from an 8 MHz clock 14 the pulse train from which is divided by 512 (i.e. the number of columns of elements into which the frame is divided), then by 525 (i.e. the number of rows of elements within each column), and then by 8 in order to match the sampling rate to the bandwidth characteristics of the audio link. The resulting pulses from divider 22 and the pulse train from clock 14 are fed to a flip-flop 24 the output of which controls an AND gate 28 to pass the pulse train from clock 14 to a counter 10 which derives therefrom the gating pulses. Flip-flop 24 is initially set to condition AND gate 28 to pass the clock pulse train to counter 10, and is reset to its other state when an output signal is developed by divider 22 corresponding to the end of the counting of all rows in the first column. Thus the reset clock pulse is inhibited by AND gate 28 from reaching counter 10, but at the same time this clock pulse sets flip-flop 24 to its initial set condition causing it to pass the following clock pulses i.e. the sampling is shifted from the first to the second column.

Abstract: 773,307. Wells. CLAUSSE, P. Nov. 25, 1955 [Nov. 30, 1954], No. 33862/55. Class 85. To increase the water collecting ability of a well a star-shaped horizontal drain 2 is formed in the water bearing stratum around the well by removing the sand &c. from that vicinity. A boring point B and tube C are pushed by hydraulic jacks radially outwards through a hole A in the well lining 1. Air or water is forced through the tube C and out through apertures in the head B to disturb the soil, then a valve at the inner end of the tube C is opened to discharge sand-bearing water which flows back through the tube C. The point B is then driven further outwards and the process repeated until sufficient distance has been covered, when the tube C is withdrawn, leaving the point B abandoned, and a shut-off valve is fixed in the hole A. The process is repeated for other holes A positioned in a circle around the lining 1.
