Abstract: 693,501. Piston packing. MAHLE, E. July 20, 1950 [Nov. 16, 1949; Jan. 28, 1950], No. 18163/50. Class 122(i) A bi-metallic piston ring comprises a one-piece light metal body I at least partly enclosing a hard metallic resilient member 2, said light metal body constituting the major bulk of said ring and having light metal surfaces, or thin wear-resisting coatings 3 thereon, through which said light metal body is adapted to serve as the principal heat conducting medium between the piston and cylinder wall. In Fig. 1 the member 2 comprises a spring steel, cast-in insert lying in a plane parallel to the side faces of the body 1 and the coating 3 is of chromium. In a modification the ring is cut from a length of light metal tubing having a helical wire embedded therein, the ring gap being made between the ends of the wire where it penetrates the side surfaces. In Fig. 4 the member 2 comprises a ring of rectangular cross-section the outer periphery of which is flush with that of the body 1, and is provided with holes 7 into which the light metal flows. In a modification apertured segments are cast-in around the outer periphery of the body 1. In a further embodiment the body 1 is formed with an internal groove into which is sprung a ring one end of which is bent radially outwards to engage in the ring gap and the other end is bent radially inwards to engage a recess in the piston ring groove. The inserted members 2 may be formed as bodies of uniform bending resistance.

Title: Improvements in automatic firearms
IPC: F41A3/10
Filed: 1946-06-17
Abstract: 639,540. Automatic guns. ZBROJOVKA BRNO, NARODNI PODNIK. June 17, 1946, No. 18196. Convention date, Jan. 7, 1942. [Class 92 (ii)] An automatic firearm with a recoiling barrel 1, and a gas piston 5 to operate the breech mechanism, is characterized in that the breech-block 7 moves transversely of the gun and by engaging with a stationary part 2 controls the movement of the barrel to its forward position. When a shot is fired the barrel recoils against the action of a spring 10, and the piston 5 which is connected to a breechblock carrier 6 partakes of a more rapid movement to compress a spring 8<SP>1</SP>. During these movements grooves 8 in the carrier 6 lift the breech-block, which has rollers 9 engaging in these grooves, and when the spring 10 expands the lifted breech-block engages a shoulder 19 in the breech casing and thus temporarily prevents forward movement of the barrel. Release is effected when the carrier moves forwardly to lower the breech-block, firing taking place, as the barrel and breech-block run forwards, by the striking of a post 17 of the carrier against the firing pin 18.

Title: Band-width reduction
IPC: H04B1/68
Filed: 1975-05-01
Abstract: 1502879 Secret transmission BATTELLE-INSTITUT EV 1 May 1975 [6 May 1974] 18233/75 Heading H4R In a bandwidth compression system an input signal from a source 1 is frequency shifted by a single sideband suppressed carrier modulation system 2, 3, e.g. using a carrier from oscillator 11 of about 10 MHz. The resulting sideband has its amplitude variations suppressed in a.g.c. unit 4 and is applied to a phase comparator 6 in a phase lock loop system 5 in which the other input to the comparator is derived from a voltage controlled oscillator 7 via a multiplier 8, and the output of the comparator controls the oscillator frequency, so that the oscillator frequency is locked to a sub multiple of the incoming signal. The output of oscillator 7 is also applied to a variable gain amplifier 9, controlled by the gain control voltage from the a.g.c. unit 4 so that the original variations of the signal input are impressed on the output of oscillator 7. The output of the amplifier 9 is shifted to base band by a modulator 10 and filter 10', the modulator being fed from carrier oscillator 11 via a divider having divider ratio which is the inverse of the multiplier ratio of multiplier 8. At the receiver the incoming signal is shifted to a high frequency range by a single sideband suppressed carrier modulation system 12, 13, the signal multiplied in frequency, by the same factor as the division in the transmitter, in multiplier 14, restored to base band by modulator 15, and high frequency modulation products removed by filter 17 to provide an output signal of similar form to the original signal. The arrangement can be used for bandwidth economy in transmission or recording or, with speech input, as a secret transmission system since the output from the transmitter Fig. I is unintelligible.

Title: Improvements in or relating to thermocouples
Inventor: BRADY ARTHUR RICHARD
IPC: G01K7/04
Filed: 1966-04-27
Abstract: 1,113,253. Thermocouples. ULTRA ELECTRONICS Ltd. 27 April, 1967 [27 April, 1966], No. 18416/66. Heading H1K. A thermocouple is formed by joining two dissimilar conductors 1, 2 in such a way that they are connected by two thermojunctions 6 to form a section of hollow pipe. Preferably, and as shown, each of the conductors consists of a hollow semi-cylinder of full 180 degrees section for a short length at one end and of somewhat less than 180 degrees section for the remainder of its length. On uniting the 180 degrees sections, e.g. by electron beam welding, the resulting structure consists of two parallel thermojunctions with a pair of common output leads constituted by the split tube beyond the joined ends. The split tube may be mounted on an insulating rod and surrounded by an insulating tube having an outer conducting sheath. Fig. 2 (not shown) depicts such a mounting fitted into a nozzle through which hot fluid flows at supersonic velocity, for use of the couple as a so-called sonic pyrometer. The fluid in the tube can flow into the pipe section of the thermocouple and out through the gaps 3 of the split tube immediately downstream of the junctions 6. The Specification mentions constructional alternatives to the one shown, in some of which there may be more than two parallel thermojunctions. Preferred thermo-electric materials are specified alloys of Au-Pd and Pd-Pt-Au.
