Title: Improvements in high speed axial flow elastic fluid turbines, compressors, superchargers and like apparatus
IPC: F01D1/26
Filed: 1942-02-11
Abstract: 586,562. Gas turbines. HALL, J. S., JENSON, G., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Feb. 11, 1942, No. 1845. [Class 110 (iii)] The outer rotor of a contra-rotational turbine or air-compressor is built up within a containing shell 14 of blade rings with free inner foundation rings and outer rings of lighter section with separate spacer rings 15 between. Flanges of the spacer rings enter between the shell 14 and turned-down portions of the outer rings. The spacer rings and outer rings are coupled together by keys which lie in recesses in their peripheral surfaces and are retained therein by the containing shell. The inner rotor may be fashioned similarly to the outer rotor around an inner locating cylinder with a stepped periphery. The spacer rings are L-shaped with flanges forming bridges for the inter-blade spaces. In a modification, the blades of the outer rotor are carried by outer foundation rings which are secured with spacer rings in the manner shown. In this case, the spacer rings of the inner rotor are similar to those of the outer rotor. Specifications 586,552, 586,553 and 586,561 are referred to.

Title: Improvements relating to pedal mechanisms for operating electric switches controlling an electrical machine
Inventor: TAYLOR LEONARD WILLIAM
IPC: H01H21/26
Filed: 1953-01-22
Abstract: 760,106. Controllers; switches held set and freed mechanically. TAYLOR (BIRMINGHAM), Ltd. C. March 15, 1954 [Jan. 22, 1933], No. 1846/53. Classes 38(3) and 38(5) A controller for an electrically-driven machine tool comprises spring- biased pedals 9, 10, 11, adapted respectively for fast, slow, and reverse operation of a machine, a trip pedal 12 being provided, in addition, to stop the machine in an emergency. Depression of pedal 9 causes its abutment 29 to engage cam 26 so that a latching device rotates against the bias of a plunger 23 and the pedal is latched in a depressed position by means of a hook which engages the abutment 29. At the same time, a spring- biased plunger 14 depresses the actuating member of a switch 4 related to the pedal 9 and the driving motor is connected for fast operation of the machine. When the pedal 9 is thus held in the depressed position, actuation of the pedal 10 to its latching position releases the first pedal, this arrangement being reciprocal. To stop the machine, pedal 12 is depressed so that arms 13 engage a bar 22 of the latching device to tilt the latter and release any pedal which is engaged by its retaining hook. The plunger 17 for the particular pedal exerts an upward thrust and returns the pedal to its normal position. The reversing pedal 11 is not latched in the depressed position since reversal of the machine is not likely to be of long duration. When the pedal 11 is depressed, an abutment thereon engages a cam for tilting the latch device and releasing either of the previously latched pedals 9 or 10.

Title: Improvements in or relating to tools for pressing sheet metal
IPC: B21D22/10
Filed: 1943-02-08
Abstract: 563,487. Stamping. PILKINGTON, F. S., and HOLMES & CO., Ltd., C. D. Feb. 8, 1943, No. 2064. [Class 83 (iv)] In stamping by means of the rubber die process in which a sheet of rubber backed up by incompressible fluid is employed, the die parts are provided with an arrangement of cylinders that in conjunction with applied distance pieces cause an increase in the fluid pressure. The lower die 1 supports the former and sheet to be stamped, it telescopes into the upper die 4, and is stiffened by a series of ribs or plates 2. The die 4 contains the rubber sheet 5 of a thickness of about half an inch and having sides fitting the die and terminating in an edge 51 by which a fluid-tight joint is made against the back plate 3 stiffened by ribs 6. The initial pressure of fluid is sufficient to cause the sheet 5 just to bulge before the entry of the die 1. When the die 1 has entered the die 4 to its full extent, a handle 29 is operated to rotate two linked cam-shafts and cause plate frames 26 supported by the ribs 6 to ring over the ribs 2 and lock the dies together. The press head is now raised and a plunger 35 is placed above a piston 13. On the next descent of the head, fluid is forced by a port 18, non-return valve 21 and port 20 to a smaller cylinder communicating with the space behind the sheet 5. The press head again rises and a plunger is inserted above the piston in the smaller cylinder and on the next descent the pressure is still further intensified. On completion of the stamping operation the pressure may be relieved in both cylinders simultaneously by raising the valve 21 from its seat by a screw 23. Instead of the cylinders, a pump or separate hydraulic intensifier may be used.

Title: Improvements in or relating to internal combustion engines
IPC: F02B75/28
Filed: 1922-01-25
Abstract: 196,393. Harrison, R. Jan. 25, 1922. Valves; valve-gear.-The valve or auxiliary piston of the two-stroke engine described in Specification 152,768, is actuated by cam gear arranged so that the tappet or connecting-rods are in tension, and means are provided for adjusting the position of the valve piston so as to vary the compression. Further, a rotary valve is described for controlling the'transfer of the charge, and an extension of the main piston for controlling scavenging ports. Cams f co-operate at their undersides with rollers h carried by frames d which slide in guides and are connected by rods c to the valve piston b. The transfer passage p is controlled by a port o<2> in a rotary valve o on the crank-shaft. Leakage between the valve o and its seating o' may be prevented by making them conical and adjustable or spring-pressed axially, or by means of labyrinth passages such as at r. When an independent compressor is used instead of crank-case compression, a chamber A<1>, Fig. 6, is provided to receive the compressed gas or air, which is then transferred by a rotary valve o' in the chamber. In this case, one cam f may be on the spindle B of the valve o<1>, and the other on a similar spindle at the opposite side of the cylinder; or the latter spindle may carry a second rotary valve o<1>. When the induction port p<2> is at the combustion end of the cylinder, it is controlled by the valve piston b, and the rotary valve o or o<1> is omitted, Fig. 7 shows the main piston k with an extension which opens a scavenging port p<3> before the induction port p<2> is uncovered by the main piston. The scavenging-air is supplied from a separate chamber in which the air is compressed by a pump element. The scavenging ports may be controlled by a rotary valve, with or without the piston extension. Regulating.-The valve or auxiliary piston b may be adjusted by rotation of a nut l<1>, Fig. 3, engaging a screwed stud b<1> fixed to the piston, and this adjustment may be effected during running by means of an extension m of the nut adapted to slide upon the spindle m<1> of a handwheel. Several nuts l<1> may be geared together for simultaneous adjustment. Lugs on the piston b engage guides on the cylinder to prevent rotation of the piston during adjustment.
