Title: Apparatus for and method of forming glassware
IPC: C03B9/16
Filed: 1942-10-02
Abstract: 560,576. Making hollow glassware. BRITISH HARTFORD-FAIRMONT SYNDICATE, Ltd. Oct. 2, 1942, No. 13882. Convention date, Oct. 4, 1941. [Class 56] Relates to the method of forming hollow glass parisons, described in Specification 532,778, in which a charge of molten glass falling into an inverted parison mould is stopped. at a predetermined level and supported by the upper part of a plunger which is moving upwards into the mould cavity. According to the present invention, compressed air is applied. to the mould cavity above the molten glass to force the glass down into the space around the rising plunger and into the ring mould. The charge of glass may be dropped through a funnel 1, Fig. 1, into the mould cavity 2 and is supported by the tip of a plunger 6 which is moving upwards into the mould cavity 2 through the ring mould 4. The-plunger tends to lift the charge of glass, but the lifting force is opposed by the pressure of compressed air which is admitted above the glass through a blowhead 9, Fig. 3, applied to the funnel 1. -The pressure of the air causes the glass to flow down around the plunger into the ring mould 4, while the plunger causes the upper level of the glass to rise nearly to the upper end of the mould cavity 2. Next, the funnel 1 is removed and the blowhead 9 is brought down to close the cavity 2, as shown in Fig. 6. At the same time, the plunger 6 is withdrawn and compressed air is applied through the ring mould 4 to expand the cavity 14 formed by the plunger on the glass. The blowhead 9 is now removed, the parison 15 is allowed time to reheat at its closed end, and the mould is opened to allow the parison, supported by the ring mould as shown in Fig. 8, to be puff blown. Finally, the parison is reverted and enclosed in a finishing mould where it is blown to its final shape. The mechanism for operating the plunger is substantially the same as described in Specification 560,672.

Filed: 1926-06-02
Abstract: 274,610. Casale, L. June 2, 1926. Oil gas.-In the production of mixtures of hydrogen and carbon monoxide free from methane from gaseous hydrocarbons and steam, or from gaseous mixtures containing hydrocarbons, oxygen and steam, the reaction is carried out at above 1000‹ C. in an excess of steam and at a pressure below that of the atmosphere. When the mixed gases are cooled to about 500‹ C. the carbon monoxide may be converted catalytically into hydrogen and carbon dioxide from which pure hydrogen is obtained after elimination of the carbon dioxide. If air or air enriched with oxygen is used in place of pure oxygen a hydrogen-nitrogen mixture such as is required in ammonia synthesis is obtained.

Abstract: 704,623. Holders for thermionic valves ;twopart couplings. CINCH MANUFACTURING CORPORATION. June 12, 1951 [Nov. 8, 1950], No. 13947/51. Class 38 (1) A method of making a socket comprises taking a piece of insulating material which is capable of flowing when heat is applied thereto, forming an opening in said piece which extends between two exterior surfaces thereof, inserting a socket contact into the opening so that it lies beneath at least one of the said surfaces, and then heating the material of one of the exterior surfaces beneath which the contact lies causing the insulating material to flow across the corresponding entrance to the opening and seal that end of the opening. The socket which is especially intended for receiving' a sub-miniature valve 4 having five contact prongs 21 arranged in a line, comprises a body 2a of a thermo-setting phenolic resin softening, e.g. at 300‹F. The body 2a has three slots 9 extending completely therethrough Fig. 6, and arranged alternately with two slots 9a Fig. 4 closed by portions 16 of the body. Slots 13, 17, connect, respectively, the slots 9, 9a, to a side 7 of the body 2a. Contacts 10 having resilient prong-engaging legs 22, 23, are positioned in the slots 9, 13, whilst slots 9a, 17, receive contacts 11 having legs 30, 31. The legs 22, 30, are laterally bowed to resiliently engage the opposed sides of their respective slots, and are thus maintained in assembly therewith. A heated iron is then applied to the body surface 6 causing the material to flow and close the lower ends of the slots 9, 13, Fig. 5. The socket is mounted on a panel 1 by passing the terminal ends of the contacts 10, 11, through apertures 40 therein and then twisting the said ends. Specification 704,658 is referred to.

Filed: 1933-05-18
Abstract: 419,749. Wireless receiving-apparatus. PARAGON RUBBER MANUFACTURING CO., Ltd., 12, Norfolk Street, Strand, and ATKINS, H. C., 335, Princes Gardens, Acton, both in London. May 18, 1933, No. 14468. [Class 40 (v).] The volume of sound reproduction in a radio receiver or radio gramophone is controlled by joint variation of the gridbiassing resistance of a high-frequency valve and a resistance connected across the intervalve coupling of a subsequent low-frequency valve. As shown, a resistance a is connected between the cathode of a high-frequency amplifier band one terminal of the output coupling coil c<1> of the detector valve c. A variable tapping a<1> on the resistance is earthed. The upper part of the resistance a thus biasses the grid of the valve b, and the lower part shunts the detector output transformer. The single resistance may be replaced by two separate resistances arranged for inverse adjustment. When the valve c has an auto-transformer output, the self-capacity of the coil is made large, to avoid loss of low notes when the volume is small.

Title: Industrial-type variable-speed centrifuges
IPC: B04B9/00
Filed: 1972-03-28
Abstract: 1389422 Centrifuges GLOBE-UNION Inc 28 March 1972 [4 June 1971] 14484/72 Heading F4G A load of lead-acid batteries 180 are centrifuged in a basket 160 rotated at variable speed within a resiliently-mounted housing 10 by means of an hydraulic motor 80 supplied with fluid directly by an electric pump 90 (or via an accumulator 222), at a pressure and flow which are limited by an adjustable relief valve 100 and control valve 104, a throttling valve 208 being operated when the pump is stopped to throttle the flow of fluid pumped by the motor 80 into the reservoir 94 to brake the basket dynamically. The batteries 180 are supported in pivoted perforated cradles 143 on a two-tier holder E which rests on flange 168 of the basket 160 during centrifuging and is lifted bodily out of the basket 160 by hoists 38, 40 on a rotatable jib 36 for delivery to a load/unload table C. Operation (Fig 12).-When pump 90 is energized, pressure transmitted by line 124 moves the spool of the adjustable throttling valve 208 against its spring to a non-throttling position so that fluid passes to the motor 80 (to rotate the basket 160 by belts 78), and returns to the reservoir 94 via lines 110, pressure relief valve 200, throttling valve 208, filter 116 and line 206. When the pump 90 is de-energized, the basket is braked dynamically and also mechanically by friction bands urged by springs to engage a portion 74a of hub 74 which is secured to the basket 160. Fluid is supplied to the motor 80 by the opening of a check valve 122. The speed of the centrifuge is detected at 84 by photo-electric or metal detecting means. Forming acid centrifuged from the batteries is drained from the housing 10 at 22. In another embodiment (Fig. 13), fluid is taken from the line 110 during dynamic braking and passed to a constant pressure hydraulic accumulator 222 until the pressure in it equals that in the line 110. Fluid may be supplied to the motor 60 via pressure reducing valve 224, to brake cylinder 232 and cover cylinder 248. The solenoid valve 230 is in circuit with the starter circuit of the electric pump motor 88. The centrifuge cover 12 is spring-biased to the open position and closed by supplying fluid to the cylinder 248. Switch 256 corresponds to the safety latch 68 (Fig. 2). The cover cannot be opened until rotation has stopped. On starting with zero accumulator pressure, the friction brakes and the cover are operated manually; alternatively the accumulator is pressurized from another source or by pump 90. In a further embodiment, the accumulator is pressurized by the pump 90, and the motor 80 is driven only by fluid from the accumulator.
