Title: Improvements in or relating to reciprocating piston compressor installations
IPC: G05D13/00
Filed: 1935-04-08
Abstract: 452,225. Gas-turbine plant. SULZER FRERES SOC. ANON., Winterthur, Switzerland. April 8, 1935, Nos. 10790 and 10791. Convention dates, April 17. 1934 and May 26, 1934. [Class 110 (iii)] [See also Group XXVIII] In plant of the type in which a floating piston reciprocating in an internal-combustion cylinder compresses air for combustion and the products of combustion are used in a gas turbine, reciprocating engine or other consumer, the quantity of fuel and air supplied to the internalcombustion cylinder are automatically controlled in accordance with the load on the consumer. A number of ways of achieving this result are described. A speed governor may control the fuel valve and/or the air suction valve, or a throttle valve in the compressed air pipe, or a valve controlling admission to the consumer. Any of these valves may be controlled in accordance with the position reached by the floating piston at the end of its compression stroke in the compression cylinder. Fig. 7 shows an arrangement comprising a combustion cylinder 3, a compression cylinder 4, and a gas turbine 2. The floating piston compresses air for use in its own combustion chamber, and the products are used in the turbine, The fuel injection pump 11 is controlled in accordance with the speed of the turbine by a governor 17, and in accordance with the position reached by the floating piston. Fig. 8 shows apparatus for effecting this dual control. The end of the floating piston 5 is connected to a lever 41 which actuates the fuel pump 11, and has a roller 43 which contacts with a sliding wedge 44 adjustably mounted on a pivoted bar 45. Displacement of this bar controls the delivery of the pump through a fluid-pressure relay 48, 56, and a valve rod 55. In certain cases the wedge 44 is adjusted by a rod 60 connected to the governor. Fig. 11 shows an arrangement in which the combustion chamber 3 has two opposed floating pistons 5, and the inlet 6 to the air-compression ends is controlled by a valve 21 under the joint influence of the governor 17 and a pressureresponsive device 82 connected to a gas receiver 85 in front of the turbine 2. In Fig. 12 the gas turbine 114 is combined with an ordinary internal-combustion engine 170 and is supplied with the exhaust of this engine as well as with the products of combustion from the chamber 102 having floating pistons. The engine 170 is supplied with compressed air from the common pipe 105 and its fuel supply is controlled in accordance with the pressure in that pipe. The governor 117 controls a valve 172 in the air inlet pipe to the compressors, and also the fuel valve 110 for the chamber 102.

Abstract: 798,112. Automatic speed control. BAUER GES., E. April 10, 1956 [April 23, 1955], No. 10855/56. Class 38 (4). An attachment for a magnetic tape sound reproducer comprises a roller over which the tape is fed, means for sensing a differential speed between the reproducer and a motion picture projector and means responsive to the sensing means for controlling the projector speed. In one embodiment, the magnetic tape 2, Fig. 1, in a tape recorder 1 is passed round a driving roller 17 on the attachment 15, which contains an auxiliary motor 19, a D.C. source 20 and a differential speed sensing device. The latter comprises a shaft 18, Fig. 2, driven by the roller 17, and carrying a sleeve 21 located by the pin 22 and slot 23 allowing limited axial movement. The sleeve 21 also embraces the shaft 27 of the motor 19 which carries a pin 26 which raises or lowers the sleeve 21 by the inclined edge 25, if the shafts 18, 27 get out of synchronism. When the sleeve is raised, a collar 28 closes the contacts 29, 30 of the switch 31, Fig. 1, to shortcircuit the speed-regulating resistance 41 of the projector motor 12, which is set to run slower than the correct speed. The auxiliary motor 19 is of the self-starting synchronous type energized from the source 20 through an interrupter 33 ... 36 mounted on the shaft 32 of the motor 12. Push-button switches 46, 47 and 44, 45, respectively advance and retard the motor 12 relative to the roller 17 for manual correction of asynchronism on starting. If the projector motor is of the A.C. induction type it is adjusted to an excessive speed, the contacts 29, 30 are arranged in series therewith and are normally closed, but are opened by the collar 28. The interrupter 33 ... 36 and source 20 may be replaced by an A.C. generator driven by the shaft 32. In a second embodiment each of the shafts 18, 32 carries an interrupter, so that the speed regulating resistance of the projector motor is shortcircuited when the shafts are out of phase, Fig. 3 (not shown).

Abstract: 436,728. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., Aden Road, Ponders End, Middlesex.-(Maattschappij Van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland) April 17, 1934, Nos. 11506 and 19431. [Class 28 (ii)] In a slice-stacker for a slicing-machine, the slice conveyer is resiliently forced towards the sliceattaching guide, so that the conveyer and the guide yieldingly engage between them, the slices being removed by the conveyer. As shown, the conveyer 21 is carried on an arm 26 pivoted at 27 and urged by a spring 30 towards the guide 50, rollers 28 at the end of the arm supporting the weight of the conveyer. The conveyer is rotated by chains, wires, bands or other inextensible flexible members 37, 38 which are each wrapped around one of a pair of one-way drive devices having returning springs, and are attached at their ends to widely spaced arms of a bell crank lever 39 also pivoted at 27. A roller 42 at the end of the lever 39 engages with a cam 43, being kept in contact therewith by a spring 44, to produce the oscillations of the lever 39 and consequently the one-way rotation of the conveyer 21. In a modification, one flexible drive member 37 only is used and is associated with a returning-spring, this producing rotational movements of the conveyer in alternately opposite directions. The conveyer comprises a number of superposed rings which are spaced apart to accommodate the fingers 24 of the discharge fly. The surfaces of the rings may be provided with a series of small depressions so that, when the slice is pressed by the guide against the rings, the suction effect holds it in position until removed by the fly. Alternatively, short pointed projections may be provided on the conveyer for holding the slice, or the surface may be without any such special provision, the natural adhesion of the slice to the conveyer being relied upon. The slice-attaching guide comprises arcuate strips 50 assembled upon vertical rigid rods 48 which carry soft resilient (rubber) rollers 49 between the strips. The rollers are at the same levels as the rings of the conveyer and press the slice thereagainst, the arcuate strips 50 serving to deflect the slice between the rings and the rollers.
