Title: Improvements in or relating to gas turbine installations
IPC: F02C6/10
Filed: 1953-06-01
Abstract: 730,126. Gas turbine plant. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.- GES. June 1, 1953 [June 3, 1952], No. 15275/53. Class 110(3). In a gas turbinecompressor installation adapted to supply compressed air to a consumer network operating at a higher pressure than the turbine, the final compression of the air for the network is effected in a separate compressor the delivery pressure of which is independent of the speed of the apparatus. The turbine 4 drives a compressor 1 which supplies air to the combustion chamber 3 through a heat exchanger 2 and feeds a separate compressor 6, driven through gearing 5 via an intercooler 7. The compressor 6 delivers air to the network 9 through a non- return valve 8, and is fitted with a by pass connection 11 provided with a valve which can be opened for no-load operation. A temperature-sensitive device 12 gradually opens the valve 10 and limits the fuel supply in the event of a prolonged excessive temperature. A turbine driving a generator may be arranged in parallel with the turbine 4. A modification employs a series arrangement of two turbines driving two compressors, the separate compressor being driven directly by the second turbine which also drives a generator. The separate compressor is fed from the first compressor or from a tapping on the second compressor.

Abstract: 1,183,935. Fluidic elements. PLESSEY B.T.R. Ltd. 5 April, 1967 [6 April, 1966], No. 15411/66. Heading G4P. A fluidic element is constructed by assembling a plurality of laminations, Fig. 1, which may be relatively located by dowel pins. Fluidic elements containing feed-backs which cause " islands," e.g. as in Fig. 2, can be constructed either from two sorts of laminations (Figs. 3, 4, not shown), a plurality of each being stacked upon the other, or by arranging that each lamination itself comprises a laminated structure for example copper-coated on to both sides of a plastics membrane (Fig. 7, not shown) so that when the copper is etched (or otherwise shaped) the central plastics membrane remains to support any islands, and finally, when the laminations are assembled the unwanted plastics portions are dissolved away. Reference has been directed by the Comptroller to Specification 1,064,780.

Title: Apparatus for greasing baking pans
IPC: A21B3/16
Filed: 1963-04-19
Abstract: 983,616. Greasing baking pans. PAR-WAY MFG. CO. April 19, 1963 [Aug. 14, 1962], No. 15502/63. Heading A4D. [Also in Division B2] In an apparatus for greasing baking pans, greasing material is forcibly ejected from an adjustably positoned spray nozzle 107 in periodic relation to the passing of baking pans being advanced past the nozzle, the nozzle being mounted on a pair of spaced, interconnected parallelogram linkages disposed in vertical planes. Baking pans 165, 166 in sets 25 are continuously advanced on endless belts 18, 19 and between adjustable guide rods 26, 27 beneath spray nozzle units 80 supplied from a heated reservoir 67 for greasing material. The nozzle units 80 are mounted for lateral adjustment along rods 78 carried by blocks 76, 77 which are longitudinally slidable along rods 74, 75, the latter being in turn carried by arms 54, 55 forming a part of laterally spaced parellelogram linkages completed by rods 57 and triangular plates 52 pivotally mounted, as at 53, to stationary posts 51. The nozzle units 80 are thereby adjustable longitudinally, laterally and vertically. A rotary wheel 144 having radial fingers 145-148 and carrying cam rollers 151-154 is mounted beneath the belts 18, 19, the fingers 145-148 being rotated by periodic engagement with the advancing pans 165, 166 and causing the rollers 151-154 to engage a cam projection 159 on an arm 155 pivoted, as at 156, and urged into engagement with the rollers by an adjustable positioned weight 161. The pivoted arm 155 carries an adjustable screw 162 which activates a valve 164 when the arm 155 is depressed due to cam motion, thereby to actuate a pneumatic system to supply air under pressure through an inlet 96 to move an air piston 92. The piston 92 integrally carries an oil piston 88 which forces greasing oil, supplied from the reservoir 67 through an inlet 86 to a chamber 87, through an outlet 103 and into the spray nozzle 107 to be discharged past the conical head 128 of a puppet 127, thereby to spray a baking pan passing therebeneath. The air supply to the piston 92 is cut off by further rotation of the wheel 144 due to the baking pan advance and the piston 92 is returned by a spring 99, the chamber 93 housing the piston 92 being continuously vented, as at 101.

Title: Improvements in or relating to the measurement of screw threads
Inventor: BARBER CLIFFORD CHARLES
IPC: G01B3/40
Filed: 1957-05-16
Abstract: 854,109. Gauging form and diameter of screw threads. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 18, 1958 [May 16, 1957; July 9, 1957], Nos. 15547/57 and 21679/57. Class 106 (2). A screw-thread gauge has parts 4, 4 adapted to make contact simultaneously with two flanks 7 of a screw thread 6 or with opposed flanks of adjacent threads, the gauge having a datum 1 and being of such shape that little more than point area of contact takes place between it and the flanks 7, and the datum 1 is maintained at the same distance from the axis of the screw thread during relative movement between the gauge and the thread, the areas of contact remaining substantially constant and travelling in effect depthwise of the flanks, if the thread is of correct form. The gauge is formed from a prism of isosceles triangular cross-section, truncated to form a triangular surface 2. The sides of the prism are undercut to form strips 4, and lands 5 are left by which the prism is gripped during machining. Fig. 2 shows the manner of use, the gauge being slid through the gap between adjacent threads and the datum 1 being maintained at a constant distance from the axis of the screw thread if this is of correct form. Other forms of gauge based on a prism of similar shape are also shown. In two of these the vertex angle of the prism section is smaller than the angle between the flanks of the thread. In one case, the vertex is rounded off, the radius of the rounded portion increasing along the length of the prism; in the other case, the vertex is cut off similarly to that shown in Fig. 1, the sides not being undercut, however. Another embodiment (Fig. 9) is used for checking internal threads. It consists of a disc 20 mounted to rotate and rock on a ball-ended spindle 23 and having a spiral portion 29 which contacts the thread and rides up and down the flanks as the disc 20 is rotated, the spindle 23 forming the datum. The devices may be used to indicate whether the thread is of correct form and also to indicate the diameter of the screw thread. Also described is a device which may be used as an attachment to the gauge and which can be used to measure both the core diameter and the root radius of the thread.

Abstract: 739,557. Rotary converting machines. FORD MOTOR CO., Ltd. June 2, 1954 [June 8, 1953], No. 16296/54. Class 35. Alternating current of substantially constant frequency is derived from the commutator of a D.C. machine by means of rotating brushes drawn round by brush friction against a speedresponsive governor. The machine, which is intended for use on motor vehicles is normally driven from the engine through a free-wheel clutch which ensures rotation in the correct direction. The armature is connected to a commutator 14 having a radial surface engaged by the rotating A.C. brushes 16, and a peripheral surface engaged by fixed brushes 18 which are used to supply D.C. and act through the conventional voltage regulator to control the voltage of the machine. When the engine is stationary, D.C. current may be fed to brushes 18 to drive the machine and generate A.C. in the usual way, the free-wheel clutch disconnecting the drive from the engine. The rotating brush carriage has slip-rings 19 for delivery of the alternating current to brushes 20 and the speed of rotation is governed by means of a weighted spring 21 which is centrifugally pressed against a friction surface 22 at a certain speed. Alternatively, or in addition, an eddycurrent braking disc or a wind-drag fan blade may be used.
