Patent GB-1054451-A (GB)
IPC: B21D51/46
Filed: 1964-03-03
Abstract: 1,054,451. Moulding crown cap liners. M. K. AICHELE. March 3, 1964, No. 8980/64. Heading B5A. A machine which provides closure caps, such as crown corks, with sealing liners comprises a continuously rotating table 14 which collects caps in notches 19 from a shoot 21, a metering device M, described in Specification 1,054,452, which deposits a measured charge of heated plastics material in each cap, and a turret S which rotates in synchronism with the table 14 and carries plungers and an anvil, the anvil and each successive plunger cooperating to mould the charge in each successive cap and to remove it from the table. To prevent subsequent premature chilling or setting of the charges the caps pass through heated chambers 28<SP>1</SP> during their movement from the shoot 21 to the metering device M. The moulding material is a thermoplastics such as polyethylene, polyvinyl chloride or a copolymer of vinyl chloride and vinyl acetate, or a thermosetting resin, e.g. a suitable epoxy resin, and is fed to the machine in granular form via a hopper 23, Fig. 2 (not shown), to be worked by an extruder screw 26 and made molten by hot air circulating in a chamber 29. The screw 26 feeds the material to the metering device M, Fig. 12 (not shown), where a measuring plunger 48 which co-operates with a check valve 51 extrudes a known quantity through a discharge passage 50. A delivery plunger comprises relatively movable inner and outer slide members 148, 134 respectively, the lower part 166 of the latter collecting the charge from the mouth of passage 50 during its downward movement, the charge thereafter being delivered to a cap when the inner slide 148 moves upwardly relatively to member 134 so that portion 162, which acts as a needle valve, is raised and a compressed air inlet 142 is uncovered. The turret S, Fig. 7 (not shown), comprises plungers 71 which are depressed and raised as the turret rotates by fixed cams 80, 84 and are each cooled by water which flows via tubes 107, 103 through a closed-bottom punch 88, Fig. 9 (not shown). Coaxial with the punch 88 are a spring urged die 96 and a knife-edged fender sleeve 90, the former allowing the formation of an annular flange on the liner C and the latter preventing contact of the plastics material with the side walls of the cap. Each lined cap is discharged from the machine by being held between a plunger 71 and the anvil 74 to remove it from the table 14 and to bring it to a discharge shoot 112, Fig. 7 (not shown). Prior to reaching the shoot the punch 71 is raised and the cap is moved by the anvil alone.

Title: Improvements relating to the Purification of Water.
Inventor: HOOVER CHARLES POTTER
IPC: C02F1/00
Filed: 1917-06-22
Abstract: 107,967. Hoover, C. P. July 11, 1916, [Convention date]. Aluminium sulphate.-A reagent for purifying water is prepared by treating bauxite, halloysite, or other mineral containing hydrated alumina, with sulphuric acid in less quantity than is chemically equivalent to the alumina and other bases. The resultant material containing both soluble and insoluble ingredients is diluted with water and added to the water to be purified, together with, if necessary, a base such as soda or lime. Powdered bauxite &c. is discharged by an elevator 1 into a weighing hopper 2, and thence into a lead-lined boiler 4 which receives sulphuric acid from a measuring-vessel 3. After some time, the mixture is boiled, diluted with water, run through a measuring-vessel 5 into a tank 8 where it is further diluted, and thence through a feedregulator 10 to the water main 12. The water, mixed with reagent, passes through a mixing tank 13 into a sedimentation chamber 15. The mixture of bauxite and acid may, before dilution, be run into an open tray or pit, in which it solidifies, and the solid be subsequently mixed with water. Specifications 3550/69, 2884/77, 25227/07, and 25228/07 are referred to.

Title: Improvements in or relating to electric capacitors
Inventor: SHEN TZU EN
IPC: H01G4/32
Filed: 1955-03-28
Abstract: 828,434. Capacitors. BRITISH DIELECTRIC RESEARCH Ltd. March 28, 1956 [March 28, 1955; May 20, 1955], Nos. 9042/55 and 14640/55. Class 37. A capacitor comprises a winding of insulating film having' electrodes formed by an adherent metal layer separated from a second metal layer by an anodized oxide film. As shown, a film 1 of polystyrene or polyethyleneterephthalate carries, as one electrode, one or more metallized layers 2 which are anodized to form the dielectric 3 on which is deposited another metal layer 4 to act as second electrode. For higher voltages, Fig. 3, either or both electrodes may be divided into a plurality of sections 11, 12, 13 and 15, 16 to provide a number of series connected capacitors. Connections are made by spraying metal on to the ends of the roll formed by the overlapping edges of electrode sections 11, 13. An embodiment is described whereby the outer electrode has the larger number of sectioned strips. Selfhealing properties are improved by dividing each series element into a number of concentric parts which are externally connected in parallel. The first electrode 2 is 0.6Á thick aluminium deposited on the insulating film 1 by electroplating after vacuum evaporation. A sectioned electrode may be either deposited in strips or divided into sections by burning off narrow strips or by the process described in Specification 742,056. As a modification, the first electrode may be of nickel (deposited by the nickel carbonyl process) on which the aluminium film, the whole of which is later converted to oxide, is deposited. An anodic oxide layer is next formed. The second electrode is deposited 0.2Á thick by vacuum evaporation, temporary masking strips being employed if a divided electrode is required. A further modification avoids the deposition of anodizable metal by using an aluminium or tantalum foil lacquered on one side then reduced in thickness by electrolytic or chemical polishing before being anodized.

Title: Improvements in and connected with governor apparatus for controlling the operation of engines or machines
IPC: G05D13/00
Filed: 1927-04-04
Abstract: 292,717. Taylor, J. L., and Taylor, A. E. April 4, 1927. Stop-gear.-A device for moving the weight of an inertia governor, e.g. Aspinall's, when the pressure of the lubricating oil or of the circulating water in a marine, internal-combustion or other engine or machine varies so that the governor will cut off, wholly or partially, the fluid-supply to the engine or machine, comprises a cylinder 7 and a piston or diaphragm 8, the cylinder being connected by a branch 9 to a supply of pressure fluid, e.g. air. The piston 8 has a stem 10 engaging the weight 1, and is kept down by a spring 12. A compressed-air supply from a storage vessel to the cylinder 7 is controlled by suitable valve mechanism operated by either or both pressures of lubricating-oil and cooling- water. The cylinder 7 may be connected to the supply through an articulated pipe. Electric means may be used in lieu of cylinder 7. The governor weight 1 is mounted on a pivot 2 and carries jaws 5 which actuate the two pawls 3 pivoted at 4. The pawl 3, Fig. 2, is in position to effect the supply of pressure fluid to the engine. When air is supplied to the cylinder 7, the weight 1 is raised and actuates the pawls, the lower pawl raises the motor-fluid control-lever and cuts off or reduces the supply. The range of speed at which the governor operates is determined by a spring cylinder and piston 13. In lieu of pressure cylinders the variations of pressure in the controlling liquids may act electrically through a solenoid mounted on the governor and actuating the weight 1. In a modification, the controlling cylinder or electric device is arranged above the weight on the governor plate and acts against the spring resistance of a device 13, the governor coming into action on the down stroke. In this construction a pawl 3 is mounted on one end of the weight.

Title: Improvements in systems for transmitting electric oscillations over power circuits
IPC: H04B3/54
Filed: 1925-04-15
Abstract: 232,608. Soc. Lerolle et Cie. April 16, 1924, [Convention date]. Wired wireless systems. - High-frequency oscillations of a frequency corresponding to a wage-length of from 50 metres down to 1 em. are superimposed &c. on D.C. or low-frequency A.C. power circuits. The high-frequency transmission may be used for telegraphy, telephotography, telautography, telephony, distant control of apparatus, lighting or power. Thus the oscillations due to a generator G may be imposed on a power line L by the two symmetrical branches H of an antenna, such that the effective length of each branch is an integral number of half wave-lengths. The branches H may be symmetrical or asymmetrical, and one of them may be near the ground; or both wires H may point in the same direction, the wire L being between them, the effective lengths of the wires being always chosen so as to contain an intergal number of half wave-lengths. The oscillations may be confined to desired regions of the power distribution system by means of wave traps or filters. Inductive means may be provided for conveying the oscillations from high to lowtension parts of the system. Oscillations of two or more frequencies may be employed simultaneously or in rhythmic alternation. Their frequencies may be varied with time to secure secrecy.
