Filed: 1935-03-23
Abstract: 458,666. Making glass bottles. PEARSON, T. F., The Poplars, Ackworth Road, Pontefract, Yorkshire. March 23, 1935, No. 9112. [Class 56] Relates to a glass blowing machine of the type in which the parisons are transferred manually by means of a ring mould holder from the parison mould to one or more finishing moulds, and a manually-operated valve is provided to control the opening and closing of the parison mould and the application of suction and compression to settle and to expand the glass in the mould. According to the invention, the machine is provided with a pair of finishing moulds, and the insertion of a parison into one mould causes the mould to close, blowing air to be applied to the parison, and simultaneously opens the other mould. The parison mould 11 comprises two hinged portions mounted above a base plate 9 having an opening to allow vertical movement of a neck-forming plunger 36. A holder 37 for the ring mould slides between the parison mould and the plate 9. The parison mould is opened and closed by a pneumatic cylinder 21, and the plunger is raised and lowered by a pneumatic cylinder 31. The rod 29 to which the plunger is attached is surrounded by a piston valve 27 which regulates the application of suction and compressed air to the glass in the parison mould by way of channels in the rod and the plunger. The parison mould is charged with glass by means of a punty, and a charge is cut off from the punty by means of shears 22 operated by a pneumatic cylinder 24 and a spring 25. The operation of the shears is controlled by means of a trip valve 58 actuated by the foot of the operator. Alternatively, the valve 58 may be controlled by a lever 45 which is used to operate a rotary valve 39. This valve controls the supply of air for operating the cylinders 21, 31, the application of suction to settle the charge of glass in the parison mould, and the application of compressed air for expanding the charge in the mould. Suctions for settling the charge is obtained by means of an ejector 54. After the parison mould opens, the ring mould with the parison is transferred by the holder to one or the other of two finishing moulds 70, 71 which are opened and closed by pneumatic cylinders 74, 75, respectively. The holder is inserted in a slideway in a blowhead 72 or 73, and it moves a valve 76 or 77 as it is placed in position. The movement of the valve causes the open mould to close and compressed air to be applied to the blowhead to expand the parison in the mould. The movement of the valve also causes the other mould to open to allow the removal of the finished article. Each of the moulds may be provided with more than one moulding cavity.

Title: Improvements in or relating to colour television receivers
IPC: H04N9/66
Filed: 1956-03-23
Abstract: 820,371. Television. GENERAL ELECTRIC CO. Ltd., and BRABHAM, H. B. S. March 25, 1957 [March 23, 1956], No. 9174/56. Class 40(3). In a matrixing circuit for developing blue, red and green component colour signals (for application to a colour-picture reproducing tube) from a received colour television signal of the N.T.S.C. type the detected Q and I components are supplied across respective resistor chains 51 ... 53 and 54 ... 58 and combined therein with the luminance signal (derived from video amplifier 59 and supplied to points C and G on the resistor chains) the values of the resistors being such that by combining the signals appearing at the pairs of points AE, BH and DF in valves 60, 61 and 62 respectively the required blue, red and green signals are developed at terminals J, K and L respectively. With this arrangement no voltage is developed across the resistor chains in the absence of a received signal. Since the load resistors are direct current coupled to the (synchronous) detectors for the Q and I components, D.C. restoring circuits are unnecessary and additionally, a lower degree of video amplification suffices since the luminance signal is effectively added twice in the resistor chains. The theory of the operation of the synchronous detectors is discussed with reference to Figs. 3 and 4 (not shown).

Abstract: 1305086 Chucks ERICKSON TOOL CO 26 Feb 1970 [12 Aug 1969] 9298/70 Heading B3B [Also in Division F2] A fail-safe rotatable value assembly 14 for a motor 12 actuating a reversible power chuck 16, comprises a first passageway 74, 78, 46 connecting to one side 40 of a piston 28, and a second passageway 48, 80, 76 connecting to an opposite side 42 of the piston. Each passageway is controlled by a check valve 54 and a spool 64. In operation, when a chuck rod 27 is to be moved to the left, air pressure is applied to the chamber 40 via a manual reversing valve 82 and the first passageway, causing valve 54 to be moved offits seat and spool 64 to be moved backwards. At the same time, the chamber 42 is exhausted via the second passageway, the check valve 54 being held open by spool 64 which is pushed forward by pressure from a passage 82 connecting with the passage 74. If the air pressure supply fails, centrifugal force moves the check valves 54 on to their slats to lock the piston, and prevent the rod 27 from moving. It is possible to reverse the pressure and exhaust connections by means of the valve 82. The passages 46 and 48 can be arranged coaxially.

Title: Improvements in or relating to Hydrostatic Bombs or the like.
Inventor: BROWN THOMAS ARTHUR
IPC: F42C5/00
Filed: 1918-01-03
Abstract: 128,250. Brown, T. A. Jan. 3, 1918. Mines, marine. - Relates to hydrostaticallyoperated. firing - mechanism for bombs, of the kind comprising a striker actuated by a spring which is automatically cocked by the movement of a pressure-operated member when the bomb is dropped into water, and is subsequently released when the bomb reaches a predetermined depth. According to the invention, the mechanism is provided with an adjusting-spring adapted to act in conjunction with a minimum - depth load spring upon the pressure-operated member in such a way as to vary the depth at which the explosion occurs. In the construction shown, the pressureoperated member is a piston D, and H, R are the minimum-depth spring and the auxiliary spring respectively. An adjustable screwed hollow plug E carries a spring-actuated striker L, a locking block J, and a slidable percussion-cap carrier G. When the bomb is dropped into water, after a half-round safety-pin 0 has been turned out of engagement with the striker L, the water, entering through passages A<1>, forces the piston upwards. This carries with it the member G, against the action of the spring H. As the part G rises, an eccentric annular flange on the block J forces the striker upwards, compressing the firing-spring M, until the striker is finally liberated by lateral displacement of the block J. This is brought about by the engagement of a conical part K<1> with a similar recess J<1> in the block. Premature release of the striker is prevented, owing to the shape of the chamber in which' the locking-block moves. In the position of the parts shown, the spring R is inoperative; but, by initially screwing up the plug E, the travel of the piston D before liberation of the striker can occur is increased, so that the spring H becomes compressed during the movement of the piston, and consequently the explosion occurs at a greater depth. In a modification, the plug E is rotatable but not axially displaceable, and is adapted, by means of cam-surfaces, to vary in an axial direction the position of an abutment for the spring R.

Abstract: 250,618. Excelsior Feuerl÷schgerõte Akt.-Ges., (Assignees of Wagener, C.). April 11, 1925, [Convention date]. Extincteurs; sprinkling-apparatus. - In a pressure-developing cartridge for fire-extinguishers wherein a vessel k of acid is broken by a striker p, r and the acid reacts with a dry carbonate m two filter chambers n, o containing different materials and separated by perforated partitions h, g are arranged above the gas-generating chambers to dry and purify the gas evolved. The chamber n is filled with a liquid . intercepting material such as glasswool, and the chamber o with a chemical substance in crystalline or granulated form, such as potassium carbonate or calcium chloride, which causes the escaping gas to follow a sinuous course. The cartridge is closed by a cover c having a central opening d sealed by metal foil e through which the striker p passes. The upper end of the latter is packed by rings t and felt u and is surrounded by a cylinder v of wire fabric which causes the gas in escaping to turn through a rightangle and so assists in drying it. In use, when the striking plate q is struck it breaks the foil e and the plate r breaks the vessel k and is then raised by a spring s. The gas escapes from the cartridge to the body of the extinguisher by apertures f.

Abstract: 627,896. Heating and cooling gases. HEAT EXCHANGERS, Ltd., and TOOGOOD, G. D. April 11, 1947, No. 9671. [Class 64(iii)] [Also in Groups XXVI and XXVIII] A gas-cleaning heat exchanger 14 is placed between the combustion chamber 5 and the gas turbine 1, and the combustion gases flow around the tubes of the exchanger giving up heat to a stream of air in the tubes. The temperature, pressure or rate of flow of the air is regulated to maintain constant the temperature of the gases reaching the turbine. The air passes through a second heat-exchanger 15 where it gives up its heat to the air flowing in the pipe 9 to the combustion chamber. The air passing through the exchangers 14, 15 is circulated in a closed circuit by a pump 18 and the pressure in that circuit is variable by means of a bleed 21 to the compressor inlet 7 and a bleed 19 from the compressor delivery 8. In an alternative form, the air passing through the exchangers 14, 15 is a part of the compressor delivery and is finally passed to the combustion chamber 5. The air may be passed through a cooler before the exchanger 14. The bundles of tubes in the exchanger 14 are arranged to act as interceptors of ash and other matter carried by the combustion gases and may be removed for cleaning. As shown in Fig. 3, two exchangers 14, 114 are arranged in parallel and one may be in use whilst the tubes of the other are being cleaned.

Abstract: 585,596. Pulse generating circuits. NATIONAL CASH REGISTER CO. May 19, 1944, No. 9752. Convention date, May 24, 1943. [Class 40 (v)] A pulse generator comprises a number of pulse producers operated in sequence to produce one pulse each, a rectifier being arranged between the output leads of succeeding producers so that each lead receives from one pulse up to the total of the number of pulse producers. The pulse generator is associated with a number of datatransmitting means which may be connected selectively with the output conductors. The gas-filled valves 10 ... 18 are normally held non - conducting due to a large negative potential on the grid, but each is connected to the cathode of the previous valve so that the rise in potential consequent upon the valve firing causes the succeeding valve to fire. The cathode of each valve is connected over a rectifier 36 to the next and to an appropriate series of denominational key switches. When the start key 26 is depressed, valve 10 fires, producing a positive pulse in the cathode which raises the grid potential of valve 11 causing it to fire. The rise in cathode potential is transmitted over rectifier 36 to raise further the potential of the cathode of valve 10, thus extinguishing it. The process is continued through the chain of valves, each feeding a pulse over the associated rectifiers to the previous valves ; valve 18 remaining conducting and being extinguished by opening the anode circuit of the valves temporarily. The pulses from each valve are fed over the denominational key switches to conductors 53, 55, 57 feeding a pulse counter.
