Title: Rotary-piston internal combustion engine with reduced by-pass flow
IPC: F02B53/00
Filed: 1969-10-03
Abstract: 1,254,629. Rotary-piston internal combustion engines. FRIED. KRUPP, G.m.b.H. Oct.3, 1969 [Oct. 5, 1968], No.48690/69. Heading F1F. A rotary-piston I. C. engine of the kind comprising a stationary casing having a double-arced epitrochoidal inner profile together with side portions to define a working chamber within which a three-sided piston planetarily rotates and having an admission-port and an exhaust port in the casing and/or side portions, includes at least one opening . 7 on the exhaust port side of the nodal point 5 which injects exhaust gas obliquely across the exhaust port 4. This prevents exhaust gases entering the induction side of the engine to decrease the amount of fresh charge, and charge temperature and reduces the knocking tendency of the engine. The exhaust gas is taken from the working chamber at a point of higher pressure at about ¥ the length of the piston side from the opening 7 and passes through a valve controlled passage 6. The valve in the passage 6 may be closed to assist starting during winter operation. In a twin unit engine exhaust gas is extracted from one unit and passed to the other unit.

Title: Cubicle switchgear
IPC: H02B11/28
Filed: 1969-10-06
Abstract: 1287301 Switchgear structures DELLEALSTHOM 6 Oct 1969 [7 Oct 1968 30 Dec 1968 7 March 1969] 49063/69 Heading H1N In a cubicle switchgear circuit breaking and isolating means 101, 102 of each pole lie on a common axis the axes of the various poles lying parallel to one another and spaced apart in a plane perpendicular to a set of bus-bars 119, the circuit breaking and isolating means 101, 102 all being assembled as a withdrawable unit which can be coupled to a truck (Fig. 5, not shown) for removal and metal screens 107 being deployed automatically on withdrawal of the unit. In Figs. 1-10 (not shown) the circuit breakers are isolated by withdrawing them from the cubicle by means of the trolley and a screw and nut coupling. The screens are arranged to be drawn out from the back of the cubicle as the circuit breakers are withdrawn and to spread out as the unit leaves the cubicle. The three poles are arranged one behind the other in the cubicle with the bus-bars above and the cable inlets below the withdrawable unit; current transformers and an earthing/shorting switch are associated with the cable inlets. The earthing switch comprises a rod inserted from the front of the cubicle and therefore can only be operated when the circuit breaker unit and its handling truck are removed; its final movement may release the front cover of the compartment housing the cable inlets (Figs. 7, 8, not shown). A dummy unit may be inserted in place of the circuit breakers (Fig. 10, not shown); this places a screen between the bus-bars and cables. The front cover of the cable compartment moves to a position to prevent withdrawal of the dummy unit allowing servicing of the cables with the bus-bars live. As the circuit breaker unit is withdrawn a screen may be drawn across its top surface (Fig. 5, not shown) by a rack and pinion device coupled with the screw and nut. In Figs. 11-14 the circuit breakers 101 are isolated, by switch blades pivoted to each terminal, prior to withdrawal of the unit. Folding shutters 107 are coupled to the linkage operating the isolating switches. The shutters 107 can only be operated with the circuit unit in place when a pin 124 on the operating shaft 106 couples with the shutter mechanism. Shaped members 116, 117 prevent operations of shutters or isolators while the circuit breakers are open. To permit access to the cable compartments the slides in which the lower shutters 107 move may be pivoted upwards when earthing blades 108 have beenmoved to engage the cables. In a modification (Figs. 15-17, not shown) the bus-bars are at the bottom of the cubicle, the cables extending to the top and being connected to the isolating contacts by conductors embedded in a block of insulating material and by plug in current transformers.

Abstract: 995,218. Tunnel diode amplitude discriminating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 24, 1963 [Dec. 27, 1962], No. 50952/63. Heading H3T. Two pairs of tunnel diodes are used in a circuit for separating signals having an amplitude within a predetermined range from other signals. As shown in Fig. 1, two pairs 3, 4; 7, 8 of similar tunnel diodes are supplied with antiphased sine or square waves of 0À2V. at 10 Mc./s. from one or two sources 1 or 5. The junctions 30, 31 are biased by currents from sources 23, 24 of opposite polarity. Pulse signals at 1 Mc./s. are fed from source 10 in push-pull to junctions 30, 31. If the amplitude of signal currents fed to junctions 30, 31 is greater than the larger of the bias currents from sources 23, 24, or smaller than the smaller of the bias currents, the signal currents arriving at the output terminal 25 via resistors 36, 37 will cancel one another, but if the signal amplitude lies within the range of the difference between the two bias currents, the signals fed via resistors 36, 37 will be in phase, giving a 10 Mc./s. output at 25. An output may be obtained only from signals above or below a predetermined range by feeding signals from source 10 in phase to the junctions 30, 31 and using bias currents of like polarity. A plurality of such circuits having different bias currents, may be interconnected by emitter followers to provide a pulse amplitude analyzer.

Abstract: 1,255,986. Making rod; working at specified temperatures. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. 17 Oct., 1969 [17 Oct., 1968], No. 51036/69. Headings B3A and B3V. Steel wire is produced by cooling the wire from an austenitic state to a temperature at which austenite is not stable, subjecting it at this temperature to one or more rolling passes, each followed by water cooling so that the rod returns to the working temperature, coiling it after it has transformed to a pearlitic structure and allowing it to cool to ambient temperature. After passing the rod through rolling strands and water cooling devices to cool it to an unstable austenite temperature e.g. 550‹ C., the rod is given a first rolling pass before transformation begins, cooled to maintain the temperature at 550‹ C., given a second pass during the transformation and then cooled again. When transformation is complete the rod is coiled to produce a rod which has spheroidized carbides and improved mechanical properties after drawing.

Abstract: 1399710 Cleaning metals electrolytically ELECTRICITY COUNCIL & COGHLAN BRIGHT STEEL Ltd 6 Nov 1973 [8 Nov 1972] 51631/72 Heading C7B An elongate metal article is cleaned by passing it continuously or stepwise through an electrolyte which does not react chemically with the metal or any contaminant thereon and applying a voltage between the article and an electrode in the bath of a magnitude such that a layer of gas or vapour covers the article surface and a discharge occurs through this layer between the article and the electrolyte, the electrolyte being maintained static or moving sufficiently slowly that, as the voltage is increased there is an unstable state where current decreases with increasing voltage, the treatment voltage being maintained above that at which the unstable state occurs. The voltage is optionally maintained within Œ 10 volts of the potential which gives rise to a current minimum at the higher voltage end of the unstable state. Iron or steel may be cleaned of oxide, grease or paint using 20% aqueous NaOH or Na 2 CO 3  or saturated Na/K carbonate. Rods, bars, tubes or sheets may be treated, passed horizontally or vertically through the bath; the article may merely contact the surface of the bath and may be rotated as it passes through. Rollers or sliding or immersed contacts may be used, the article being desirably cathodic, although anodic and A. C. treatment is possible. As anode, nickel or stainless steel is suitable in the form of a hemisphere, a squirrel cage of rods (through which the article may be passed) or a sheet. The cell used may have a seal through which the article passes into the bath, electrolyte being pumped in and overflowing into a tray below the cell for subsequent cooling and/or filtration and recirculation. In one embodiment a flat sheet is passed over the surface of electrolyte overflowing from a central raised portion of a rectangular cell. In examples a current of 75-125A is used at 150V, with an electrolyte flow of 10 l/mm.
