Title: Improvements in or relating to internal-combustion engines
IPC: F01L5/08
Filed: 1921-01-20
Abstract: 178,910. Wade, H., (Cage, J. M.). Jan. 20, 1921. Valves.-A two-stroke engine is provided with separate air and mixture admission ports near its ignition device and an exhaust port remote therefrom, and has valve means arranged so that, as the piston approaches the end of its power stroke, the exhaust port opens, air port opens, mixture port opens, air and exhaust ports close substantially together, and mixture port closes, in the order named. Fig. 1 shows a cylinder 12 fitted with sleeve valves 15, 16 and with a pair of pistons 17, 18 working on opposite sides of a partition 26 carried by the sleeve 15. On the down-stroke, the piston 18 draws in air below the partition through ports P<7>, 104, 105, and on the up-stroke forces this air through ports 106, 107, P<8> to a manifold 35, from which the air is delivered to the combustion head through ports P<2>, 92, 93, 14e, while the exhaust ports 90, 91, P<3>, P<4> are still uncovered. The piston 17, on the up-stroke, draws in air through ports P<6>, 100, 101, and on the downstroke forces that air through ports 102, 103, P<5>, and past a carburettor arranged in a manifold 45<a>, the carburetted air being afterwards admitted to the combustion chamber through ports P<1>, 94, 95, 14<d>, near the bottom dead-centre. Specification 178,222 is referred to. Valve-gear.-The sleeve valves are reciprocated by eccentrics E<1>, E<2>, each of which actuates the outer sleeves of two of the cylinders and the inner sleeves of the other two cylinders. The eccentric arms are connected respectively by arms 70, 72 fixed to concentric countershafts 71, 73. An arm 74 on the shaft 71 is connected by a rod 75 to a lever 76 operating the outer sleeves 16 of two cylinders in opposite directions, and another arm 86 on the shaft is similarly connected to a lever operating the inner sleeves 15 of the other two cylinders. Similarly, an arm 82 on the sleeve 73 is connected by a rod 83 and lever to the inner sleeves 15 of the first pair of cylinders, and by an arm 78, rod 79, and lever 80 to the outer sleeves 16 of the second pair of cylinders. The outer sleeves move slightly ahead of the pistons, and the inner ones slightly behind them. Regulating.-The air-inlet ports P‹ are controlled by a hand-actuated valve 42, and the air inlets P<7> by a similar valve, or by two valves 38 connected by a rod 39.

Abstract: 607,167. Furnaces. STEIN & ATKINSON, Ltd., and WILLIAMS, C. H. Jan. 28. 1946, No. 2733. [Classes 51(i) and 51(ii)] In an annealing, hardening, carburizing or like furnace of the kind wherein the goods under treatment are enclosed under a fixed or removable cover, and are heated by radiant tubes, at least some of the radiant tubes are vertical, or substantially vertical, and are arranged to exhaust combustion products into the lower part of the furnace. As shown, tubes 9 exhaust downwardly and the alternate tubes 10 exhaust upwardly into the space enclosed by the outer cover 5 which carries the tubes, the cover having a depending web 6 which enters a sand seal 2. The goods are supported on a platform 3 and are enclosed by an inner cover 4. Eyes 7 on the cover 5 engage pillars 8 and ensure accurate positioning of the cover 5 on the base 1. The tubes, which may have internal baffles of known type and may be of non-circular or non-uniform section, are supplied with gas and air from manifolds 11-14, the air supply being from a motor-driven fan mounted on the cover 5. The gas manifold is supplied by a flexible pipe having a quick-release coupling connection with the main gas valve. Reducing gas may be admitted through a pipe into the cover 4. The sets of tubes 9, 10 may be controlled manually and separately, or controlled automatically, e.g., the tubes 9 may be controlled by a thermocouple in the lower portion of the furnace or charge, and the tubes 10 by temperature-responsive means located in the upper portion of the furnace or charge.

Title: Improvements in transponder devices
IPC: H04B7/155
Filed: 1952-02-05
Abstract: 698,025. Radio signalling. MARCOU, J. C. P. Feb. 5, 1952 [Feb. 7, 1951], No. 2987/52. Class 40 (v). A transponder comprises a receiver 1 and retransmitter 7 connected by a narrow passband filter, e.g. H.F. amplifier 5, and gating means 2, e.g. a quench oscillator, arranged to block in phase opposition the receiver and retransmitter so that the retransmitted waves have no effect on the receiver, and yet the frequency band of the retransmitter is derived from that of the incoming waves. The bandwidth of the receiver preceding the filter, and of the retransmitter are large in relation to the gate frequency to prevent interaction. Preferably the received waves are reduced in frequency by a local oscillator 4 before passing to the filter 5, then the filtered waves again increased in frequency by that of the oscillator 4. The filter output and hence retransmitted waves may occupy a frequency band the same as or differing by a multiple of the quench frequency from that of the received waves. Both the received and retransmitted waves may be modulated frequency multiplex signals. The out-ofphase rectangular pulses from the quench oscillator 2 preferably are separated by quiescent intervals. Specifications 574,627, 611,727 and 679,154 are referred to.

Abstract: 1394823 Slings F NATTRASS 8 May 1972 [26 May 1971 29 July 1971 21 Jan 1972] 17216/71 35663/71 and 3013/72 Heading B8H [Also in Division E2] A load encircling sling comprises a discontinuous length of material 1 and a continuous loop of material which are joined by means of two pairs of chain links 6, 7, one part 3 of the continuous loop engaging with the upper part of the load 2 while its other part 4 is engaged by a lift hook 5. On raising the load by means of the sling the link 7 is drawn towards the link 6 on movement of the loop material about the limbs of the chain links 6, 7, the part 4 of the loop lengthening and the part 3 being shortened and thus drawing tight about the upper part of the load 2. By means of this arrangement loosening of the sling is assisted when it is deposited after release of the lifting force. In a further embodiment the loop (3, 4) is connected to a bar (9) which spans a chain link (8) to which the lower sling part (1) is attached, Figs. 3, 4 (not shown), while in a still further embodiment the loop (3, 4) is inserted through a loop formed in the lower sling part (1), Fig. 8 (not shown). The lower part of the sling may be formed as a multiloop sling, Figs. 9-11 (not shown), the loops of which pass upwardly about the corners of a load and are connected to continuous loops of material (21), Fig. 12 (not shown).

In examples 1-cyano-vinyl ethyl carbonate is polymerized in bulk in the presence of benzoyl peroxide under nitrogen, and copolymerized with styrene under similar conditions. Other suitable polymerization catalysts include persulphates, e.g. potassium persulphate.  Other comonomers specified are vinyl esters, vinylidene chloride, acrylic and methacrylic acids and their esters, nitriles and amides, substituted styrenes, esters and amides of fumaric, citraconic and maleic acids, and olefins.  The polymers can be moulded into articles such as blocks, sheets and films.ALSO:Compounds of the formula <FORM:1111796/C2/1> wherein R is a C1-20 alkyl (including cycloalkyl and aralkyl) group may be obtained by reacting an alkyl haloformate with 2-chlorolactonitrile in the presence of an alkaline reagent to form the 2-chloro-1-cyanoethyl alkyl carbonate and then dehydrochlorinating the later by reaction with a tertiary amine thus forming the 1-cyanovinyl alkyl carbonate.  The products may be stabilized with a phenolic stabilizer, e.g. t-butyl catechol, and they are stated to possess anthelmintic properties.
