Title: Improvements in Trap-Shooting Launchers
Inventor: NEWILL GEOFFREY FREDERICK
IPC: F41J9/18
Filed: 1966-11-11
Abstract: 1,194,681. Trap-shooting launchers. G. F. NEWILL. 13 Nov, 1967 [lil Nov., 1966; 9 Aug., 1967], Nos. 50641/66 and 36503/67. Heading A6D. A trap-shooting launcher for disc targets comprises a rotary shaft 3 with driving means 2 for continuously rotating the shaft in one direction, at least one launching arm ,5 extending radially outwardly from the shaft, mounted to rotate therewith and having means to support and guide a disc target 8 to roll outwardly along and be launched from the arm under the effect of centrifugal force when the shaft is rotated, means 12 for frictionally holding the disc target in the launching anm against the effect of centrifugal force and means for releasing the disc target. As shown a pair of arms 5 are of channel cross-section of width somewhat greater than the diameter of a disc tanget 8 which rests on a pair of low-friction running strips 9, on the web of the arm 5, and laterally against a friction strip 10 oif rubber for example, along the inside of one side flange 11 of the arm 5 are mounted on hinges 6 and inclined upwardly at a suitable angle which may be adjustably fixed by means of supporting bolts 7 in a cradle 4 carried on a shaft 3. To launch a pair of targets loaded into the arms 5, the motor 2 is switched on and rapidly accelerates, rotating the shaft 3, cradle 4 and arms 5 at an increasing speed until the centirifugal force acting on the targets causes them respectively to overcome the frictional restraint of a blade spring detent 12 anchored by one end to the inside of the other flange 13 of the arm 5 and bearing tangentially against the rim of the target with a load which is adjustable by a screw 14. As each target escapes past its detent 12, it Tolls rapidly along the friction strip 10 and is flung from the arm 5 with a high rate of spin about its own axis. The heavier the load imposed by the detent 12, stressed by the screw 14, the longer the period and the higher the speed of rotation of the arm before release and thus the greater the linear speed and flight of the target. With the spring detents 12, the direction of launching of the targets is unpredictable, but one or both targets may be launched in a known direction by replacing one or both spring detents by a hinged gate held across the arm 5, to bar escape of the target, 'by a catch which projects 'below the web of the arm 5 to strike an abutment trip position on the base 1 at an angular position to he encountered by the catch to release the gate and free the target to be launched in the required direction. The catch may be mounted, such as on a weighted blade spring, so that its path progressively lowers, under centrifugal effect, as the rotational speed increases and does not reach the horizontal plane of the abutment trap until a desired speed has 'been achieved. Another modification is described.

Abstract: 1,034,376. Coding and decoding apparatus. ANSTALT EUROPAISCHE HANDELSGESELLSCHAFT. Sept. 17, 1963 [Sept. 19, 1962], No. 36538/63. Heading G5X. A visual coding and decoding system comprises a chart 1a containing parallel rows of randomly arranged characters disposed so as to co-operate with an ordered row of characters on a sliding arm 16. The particular row, which may correspond to each word or letter of the text to be encoded, is selected by means of a keyboard-actuated device 3 and pulley arrangement shown. Having located the desired row, the letter to be encoded, E say, is located on the sliding arm and the corresponding code letter Z is found directly above in the adjacent chart row. Decoding for this row is the reverse of this procedure. In a further embodiment decoding is made easier by having a decode row either on the back of the chart (Fig. 1a, not shown) or grouped with the code row on the front of the chart (Fig. 1b not shown), the code letter Z is then located on the slide arm and the decode letter E read off from the decode row. The slide member may be provided with a viewing window which may be additionally adjustable by pegs with the code or decode row (Fig. 2, not shown). In further embodiments the chart may be in the form of a scroll or an endless band or may be cylindrical.

Title: Improvements in combustion chamber assemblies
Inventor: CHEESEMAN HERBERT LARCOMBE
IPC: F23R3/60
Filed: 1959-10-28
Abstract: 909,580. Generating combustion products under pressure. GENERAL ELECTRIC CO. Oct. 28, 1959, No. 36557/59. Class 51 (1). In a combustion chamber assembly comprising a louvred flame tube having a louvred end dome and a cowl forming with the dome a dome cooling chamber, a series of circumferentially spaced openings are formed in a cylindrical portion of the cowl and the series of intervening elements so formed are secured to a cylindrical portion of the dome. In addition, a series of circumferentially spaced offset areas on the upstream end of the flame tube are secured to the cylindrical portion of the dome between the cowl elements so that the dome, cowl, and flame tube are nowhere joined by more than two thicknesses of material. The openings may be situated along the edge of the cylindrical portion of the cowl so that the intervening elements are formed as fingers. The offset areas of the flame tube provide axial channels for the flow of coolant over the inner surface of the flame tube. As shown an annular combustion chamber assembly 11 for gas turbine engines comprises a flame tube having inner and outer shells 14, 12 defining a combustion chamber 22, a dome 16 and a cowl 18. The outer shell 12 has an upstream end portion with the offset areas 73 extending radially inwardly and defining axially extending channels 74 which portion overlaps fingers 70 extending from a cylindrical portion 58 of the cowl 18. The fingers 70 are welded to a cylindrical portion 54 of the dome 16, between the offset areas 73. In forming the offset areas 73 louvre openings 82 extending radially inwardly from the shell 12 are produced. The offset areas 73 are separated by parts 84 of the shell 12 and louvre openings 88 are formed between the parts 84 and the fingers 70. The thickness of the stock of which the cowl, and flame tube are made is less than the radial depth of the offset parts so that the louvre openings 82, 88 and therefore the film of cooling air extend almost completely round the flame tube. The radially inner limbs 52, 64 of the dome 16 and cowl 18 respectively are similarly joined to the radially outer surface of the inner shell 14. Apertures 45 in the cowl 18 and apertures 46 in the dome 16 are formed to receive fuel nozzles. The area of each aperture 45 is greater than that of its fuel nozzle permitting a flow of air from a plenum chamber 6 into the dome cooling chamber 42. Louvres 90 and 92 are formed circumferentially in dome 16 to permit the flow of cooling air from the chamber 42 along the cylindrical portions 54, 60 of the dome 16.

A controlled rectifier consists of a semiconductor body containing at least four successive layers alternately of opposite conductivity types, the first layer being in several sections, one of which has the function of control electrode and the others of which are interconnected and connected to the second layer by ohmic contacts. The fourth layer of the series has an insert formed in it opposite the control electrode which insert is connected to said layer by an electrode extending over it. Alternatively, opposite the control electrode the last layer includes a zone at least at its surface of lower conductivity than the rest of the layer, or has had a zone cut out of it at this point. In each case the effect is to direct current away from this part of the device. In the arrangement shown in Fig. 1, the body is of silicon, regions 2 and 3 were formed by diffusion of acceptor impurity into an N-type base wafer, and concentric annular regions 5 and circular region 6 formed by alloying donor impurity to region 2. The regions 5 are interconnected by annular ohmic contact 7. In this case the outer part of the region 3 bounded by projection lines 10, 11 has had its conductivity reduced or its conductivity type changed by-inward diffusion of donor impurities before ohmic contact 8 was soldered on Alternatively, the solder used in attaching the electrode has a donor content where it overlies this region to produce the same effect. In other arrangements the outer part of region 3 bounded by lines 10, 11 is removed and preferably replaced by solid insulating material before attachment of contact 8 or the part of region 3 bounded by the lines is subsequently removed down to the PN junction together with the overlying part of contact 8.
