Title: Improved Telemetry System for Pistons and Like Reciprocating Members.
Inventor: SLAFFER MARK
IPC: G01K1/02
Filed: 1967-04-12
Abstract: 1,182,152. Measuring temperature electrically. M. SLAFFER. May 9, 1968 [April 12, 1967], No. 16678/67. Heading G1N. A signal indicative of a parameter, e.g. temperature or displacement, of the piston of a cylinder or a like reciprocating member is transmitted to a first position on an electric conductor to which a receiver is capacitively coupled at another position. As shown, a thermistor 5 on a piston varies the frequency of a transmitter 6 which is connected via capacitor 7 or flexible insulated copper wire to one end of a copper strip attached to the piston connecting rod and then via a capacitance 10 formed between the strip and a stationary curved plate to a receiver 9. The arrangement is such that the value of capacitance 10 remains substantially constant despite movement of the piston. The receiver may be tuned to the input signal frequency or may convert the frequency varying signed to an analogue signal which is recorded. Displacement is measured by causing to vary the proximity of a metal member to an air-cored coil carried by the piston and forming part of a tuned circuit of transmitter 6. For multi-channel operation the strip 8 is arranged to be common to all transmitters and receivers which operate at a plurality of different frequencies. Alternatively, each of a plurality of sensors may be connected to one channel by a switch operating a number of times for each stroke of the piston.

Title: Improvements in kinematograph or photographic color film material and methods of manufacture
IPC: G03C7/04
Filed: 1924-07-16
Abstract: 231,058. Thornton, J. E. July 16, 1924. Colour photography.-Raw film material for the production of multicolour photographic or kinematographic positive pictures of the kind described in Specification 224,570, which are built up by cementing together two elements each carrying two colour-component images, comprises a transparent support such as glass, celluloid, or thin tissue, two parallel strips of sensitized colloid each comprising elements in two colours juxtaposed in the same layer in the form of dots, lines, or other pattern, the colours being all different and representing the components of a four colour picture. In a modification for three colour work, one colour is duplicated in both strips. The strips may each be prepared by scattering, upon a layer of absorbent colloid, grains of colloid dyed and mordanted in one of the two colours, rolling the grains into the surface, and dyeing the interspaces with the other colour. Alternatively a mixture of grains dyed with the two colours may be scattered on and rolled in, or a set of lines or a pattern of one colour may be printed on the colloid in mordanted dye, and the interspaces be dyed with the other colour. When a pattern is produced on kinematograph material by printing, the pattern is so formed that the dots, lines, &c. do not recur in the same place in successive picture areas, in order to avoid the appearance of pattern or grain in the exhibited pictures. The colloid strips may be sensitized with bichromate, or with silver salts of the rapid or slow varieties. For kinematograph pictures, thin material is used of half standard thickness, and is reinforced by a strippable layer of porous paper, which is removed before the finished component picture strips are cemented together. Instead of using a film carrying both component strips, which is finally severed before cementing, each strip may be coated on a separate support. The material may carry register marks or holes to facilitate assembling the components, and also in the case of kinematograph films, the usual traction perforations. Specifications 13711/14. 8300/15 and 214,934 are referred to.
