Title: Moulding apparatus and a filling device for use therein
IPC: B29C41/18
Filed: 1974-03-29
Abstract: 1462533 Moulding apparatus BATA INDUSTRIES Ltd 29 March 1974 [30 March 1973] 14098/74 Heading B5A A series of moulds 4 on carriers 3 are fed sequentially along a continuous track 7 by a chain 10, during which they are filled by a dispenser 100 on a carriage reciprocable along a relatively short track 18 parallel to the track 7. The carriage and a mould carrier are interengaged and moved together in the direction of the arrow A, Fig. 2, during the filling operation, following which the carriage is returned to its initial position by a counterweight 93, Fig. 1, to receive the next mould in the line. Each mould, during its travel, operates a stationary switch 69 to effect the said inter-engagement and cause movement of the carriage; the carrier then actuates a switch 162 to start the dispensing operation which is stopped by the operation of a switch 152 by a cam 150 on the carriage. The moulds are for the slush moulding of footwear, and the dispenser fills the heel cavity. The switch 69 is adjustably mounted and operated by the heel part of the mould. The interengagement between the carrier and carriage is effected by a plate 19 pivoted at 21 on the carriage; when held in its lowered position by the operation of a clutch on the carriage, movement of the carrier effects the carriage drive. On declutching the plate 19, the carrier moves the plate about its pivot and allows the carriage to return and strike the plunger of a cushioning cylinder 89 which has been previously extended by the operation of a switch 154 by the carriage. A safety switch 156 shuts off the apparatus should the carriage advance beyond a predetermined position.

Title: New or improved fuel circulation system in a gas-turbine engine installation
IPC: F02C7/22
Filed: 1960-04-22
Abstract: 892,868. Gas turbine plant. DAIMLER-BENZ A.G. April 22, 1960 [April 24, 1959], No. 14232/60. Class 110 (3). [Also in Group XI] A fuel system for a gas turbine plant comprising a compressor supplying combustion air to a combustion chamber feeding a turbine driving the compressor has a fuel pump driven by the compressor turbine supplying fuel to spill-type burners in the combustion chamber through a regulating mechanism and pressure differential mechanisms for maintaining the pressure drop across the regulating mechanism constant and for controlling the return flow in the spill line. The invention is described with reference to a gas turbine plant comprising a compressor supplying combustion air to a combustion chamber feeding a turbine driving the compressor and an independent useful power turbine. A fuel pump 42 driven by the compressor turbine supplies fuel to the injection nozzles 60 through a pipe a containing a fuel regulator C. A pressure differential regulator 45 maintains the pressure drop across the fuel regulator C constant by by-passing fuel back to the suction of the pump. The piston valve 40 is moved in response to the compressor discharge pressure. The spill pipe b2 contains a flow regulator 47 which maintains the flow in the spill line constant. The pressure in front of an orifice 67 acts in chambers 68, 69 against the pressure at the downstream side of the orifice acting in chamber 70 and the load of the spring 71. A control piston 73 attached to a diaphragm 72 maintains the flow constant. A pipe c contains a valve 74 which is operated in response to overspeed of the power turbine, to by-pass fuel back to the pump suction.

Title: Improvements in or relating to electric liquid-break circuit breakers
IPC: H01H33/92
Filed: 1938-05-13
Abstract: 514,704. Liquid-blast switches. GENERAL ELECTRIC CO., Ltd., and GARRARD, C. J. O. May 13, 1938, No. 14322. [Class 38 (v)] In a circuit-breaker of the liquid-break type, upon movement at break of a contact away from a complementary contact, liquid contained in the first contact or an extension thereof is arranged to be injected positively into the space vacated by the contact, the volume of liquid injected into the said space being substantially equal to the volume of the space. An earthed plate 5 supports an insulating cylinder 4 which is filled nearly to the plate 5 with oil and is provided with a bottom closure 15 having a drainage hole and carrying a fixed butt contact 18 which is slightly offset from the centre of closure 15. Cylinder 4 is lined with an arcresisting cylinder 19 below which is a similar cylinder 20, which in turn is lined with insulating cylinders 21, 22 and contain an arc-control device (not shown). A frusto-conical part 25 of a metal cylinder carries a circular metal plate 26, an aperture in which is covered by a flanged sleeve-like member 28 supporting a condenser bushing 29, the lower end of which carries a protecting insulator 34. The hollow movable contact unit 3 comprises the contact proper 38, the extension 39, and parts 40, 41 capable of relative movement, the whole being guided by a metal sleeve 36 in the base of a metal cylinder 35 fixed within the bushing 29. The cylinder 35 also carries a cross bar 43 which engages in slots 42 in the part 40 and supports a fixed piston 44. The length of part 41 is about half that of the unslotted part of 40, and a compression spring 47 acts between its upper end and a flange 48 at the top of the unslotted part of 40, the spring being enclosed within a cylinder 49 fixed to the top of the part 41 and having a stop 50 for limiting the movement between 40, 41. A second spring 37, which is stronger than 47, acts between the guide 36 and a flange 51 on the cylinder 49. To open circuit, the part 40 is moved upwardly, aided by spring 37, and as the contacts separate, relative movement between 44 and 40 forces oil through the extension 39 into the space vacated by the contact, the volume of liquid transferred being substantially equal to that of the space. When cylinder 49 reaches the cross bar, the part 41 is arrested, but the part 40 continues to move, aided by the spring 47. The reverse operation occurs in switching on again. The arrangement is applicable also to downwardly or horizontally-movable contacts.

Title: Improvements relating to processes and apparatus for gasifying liquids
IPC: B01F27/91
Filed: 1959-04-27
Abstract: 877,652. Aerating liquids; yeast production. PATENTAUSWERTUNG VOGELBUSCH G.m.b.H. April 27, 1959 [April 29, 1958; Feb. 18, 1959], No. 14323/59. Classes 14 (1) and 14 (2). Relates to a process for aerating liquids in which use is made of " mammoth pump effect," this being the movement of liquid in a tubular body immersed in the liquid produced by gas bubbles introduced into the liquid in the lower part of the tubular body. This produces in the tubular body a liquid-gas mixture of specific gravity less than that of the ungasefied liquid surrounding the tubular body and consequently the movement of the lighter liquid in the tubular body and circulation of the liquid. According to the invention in the process, which may be used in the fermentation of yeast, gas is supplied to the liquid by means of a rotating distributing device and the liquid is caused to circulate by " mammoth pump effect," the distributing device comprising a channel open on one side which is rotated at such a high speed that firstly, the gas builds up in the liquid behind the channel a vacuole from which gas enters the liquid in the form of large and small bubbles and that secondly, the small bubbles take part in the circulation of the liquid which is brought about by " mammoth pump effect " caused by the large bubbles escaping from the surface of the liquid. Apparatus for carrying out the process may be as shown in Fig. 1 in which a central cylinder or tube b is provided in a vessel a. A hollow rotary shaft c is disposed in the tube b and is provided with a gas distributing device e in the form of two blades of semicircular cross-sections Gas is supplied to the device e from the hollow shaft c. Fixed radial blades g 1 , g 2  prevent the liquid in the tube b from being rotated except in the immediate vicinity of the device e. In a modification the device e, Fig. 8, extends through the central tube b into the annular space a/b and sweeps through this, the open channel portions being arranged in the outer annular space and the liquid therein is thus gasefied. Circulation therefore takes place in the opposite sense as shown and the retarding blades g 1 , g 2  are provided in the annular space.' In another modification a stationary gas supply pipe k, Fig. 9, is used instead of the drive shaft c and the tube which guides the circulatory flow is constructed as a cooler in the form of a cold water coil or duct b 1  which is connected to inflow and outflow ducts b 2 , b3. A detailed, comparative example discloses substantially increased efficiency of yeast production when using the above-described aerating process for supplying the oxygen required and removal of carbon dioxide formed.
