Title: Improvements in or relating to container closures
IPC: B65B51/09
Filed: 1966-06-13
Abstract: 1,146,477. Sealing containers. PRESS & CO. K.G. MASCHINENFABBIK. 13 June, 1966 [22 June, 1965], No. 26236/66. Heading B8C. A filled container 26 is sealed with a plastics film by lifting through and entraining in the softened film 2, means such as compressed air or vacuum drawing then being used to press the film 2 about the walls of the container 26. In the preferred embodiment the film 2 is fed intermittently from a roll (1), Fig. 1 (not shown), a suitable length being cut by cutters (5, 6), after which the cut portion is fed on to a support 8, Fig. 2, and across an aperture 9 therein. A punch 10 is then lowered, the film 2 being retained over the aperture 9 by a spring- biased holder 18 mounted on the punch 10, and an edge-cutter 21 having a serrated cutting edge, Fig. 6 (not shown), perforates the film around the perimeter of the aperture. The film 2, Fig. 2, is softened by spraying with a solvent in liquid or gaseous form, or by heat. A lifting table 28 carrying the container 26 is then raised through the aperture 9, the rim 27 of the container engaging the softened film 2 and pressing it upwards against a resiliently mounted plate 24, which moulds it into the container mouth to form a depression therein. Subsequently the punch 10 is lowered further to sever the film 2 completely around the aperture perimeter, and the film is pressed into conformity with the outer wall of the container either by compressed air directed from above, or by a vacuum established below. When the film has re-solidified the table 28 is lowered and the sealed container is discharged, an out wardly directed serrated flange (34), Fig. 5 (not shown), formed by the shaping of the film against an upper rim 30, Fig. 2, of the table 28, providing a grip for handling and opening of the container. The operation of the moving parts of the apparatus may be by pistons controlled by the air which is used to shape the film. Oil may alternatively be used both for shaping and control. A series of such devices may be arranged in an endless chain, capstan or turret type machine.
Patent GB-389532-A (GB)
Title: Improvements in or relating to the moulding of articles of or containing rubber or other organic substances
IPC: B29C37/00
Filed: 1931-09-19
Abstract: Relates to a method for simulating on articles of rubber or like organic material, the surface markings of a selected pattern article of leather, skin, or such like material.  The leather or like article may be used directly as a former, in which case the markings would be inverted or in mirror fashion.  Preferably, however, the leather or like article is used as a mould to produce negative replicas which are then used as formers to produce positive copies of the original. The copies may be produced by dipping, spreading, spraying, moulding or electrophoresis from aqueous emulsions or dispersions or solutions in organic solvents of such organic materials as rubber (including artificial, coagulated, vulcanized, waste or reclaim), guttapercha, balata or similar resins.  Concentrates such as described in Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], may be used.  Since leather, skins, &c. are substantially nonconducting, electrophoresis can only be employed when conducting replicas are first made.  If it is necessary to distend or make rigid the leather or like article, this may be done by introducing air or other fluid, or powdered substances such as soapstone, unbaked clay, or sulphur either alone or mixed with waxes or other materials.  In some cases, it may be sufficient to secure the article, e.g. by adhesion, to a rigid backing.  Replicas may be made by turning the leather article inside out and filling it with plaster of Paris, a positive casting is made from the plaster of Paris negative, and this positive is used to produce more durable negatives, e.g. of metal or ceramic material, on which the copies of the original article are formed.

Title: Improvements in or relating to the delivery of liquid
IPC: F02M59/36
Filed: 1924-11-06
Abstract: 248,427. Invernairn, (W. Beardmore), Lord, and Chorlton, A. E. L. Nov. 6, 1924. Eccentric-actuated pumps; two barrels in series; regulating delivery by opening suction valves.-A positively operated piston or plunger type pump is provided with a positively operated valve which moves across the liquid stream passing to the pump and which at its highest speed closes and opens the suction and also operates to cause the pump to effect delivery during the middle portion of its stroke. The valve may be regulated to control the extent of the delivery portion of the pump stroke, and the supply to the pump is effected by a constant pressure auxiliary pump with an intermediate expansion chamber. Liquid, and specifically fuel for an internal combustion engine, is supplied by a rotary pump B by' the pipe C, which has an expansion chamber D to the suction pipe C' of the main pump G which is driven by an eccentric H. A lever J mounted on an eccentric pivot J<2> is actuated from a collar G<1> on the pump and operates a valve E adapted to move across the pipes C, C<1>. The valve is a solid rod with cutaway portions E<1>, E<2>, the intermediate part having helical edges whereby the period of opening can be regulated by turning the valve on its axis by mechanism F. From the pump a delivery pipe K passes to a valve L which distributes fuel to two fuel nozzles O. The valve E opens the pump to the supply pipe on its suction stroke and also during the earlier and latter portions of its delivery stroke, but is closed during the middle portion of this stroke when the fuel is then passed to the nozzles. During delivery there are therefore pulsations in the passages C<1>, K.

Title: Improvements in transistor direct-current converters
IPC: H02M3/338
Filed: 1959-08-07
Abstract: 911,862. Transistor inverters. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 7, 1959 [Dec. 11, 1958; July 15, 1959], No. 27098/59. Class 40 (6). [Also in Group XXXV] In a transistor inverter of the type in which a transformer provides regenerative feed-back between the output and input of one or more transistors to cause a switching action to occur, excessive input current to or output current from the inverter causes a large current to flow in an auxiliary winding of the transformer so that the switching action ceases. Push-pull arranged transistors 1 feed a transformer 2 having a feed-back winding 5 and an output winding 7 which may be coupled to a filter to provide a sinusoidal output wave or to a rectifier and smoothing system 9, 10, 11 to provide a D.C. output voltage at 8. If, for example due to a heavy load, excessive current flows through the rectifier or through the transformer the voltage across a resistor 13 connected in the supply circuit rises sufficiently to cause a transistor 14 to conduct and operate a relay 19. Contact 16 of this relay short-circuits a winding 12 on the transformer so that the feed-back becomes insufficient to sustain oscillation. Contact 19 of the relay changes over from a position in which a capacitor 20 is charged from the supply 4 to a position in which the voltage across the capacitor is connected to the base of the transistor 14 so that the transistor remains conductive until the capacitor has discharged. When this occurs the transistor 14 becomes non- conductive and the relay 19 releases. If excessive current still flows, the relay is immediately operated again. Resistor 17 is adjustable to set the maximum allowable value of input current to the circuit. It is suggested that the transistor 14 could alternatively be controlled by connecting its base-emitter circuit across a capacitor 24 so that the transistor becomes conducting when the output current exceeds a predetermined value.

A mould for concrete blocks comprises hinged sides and ends attached to a table top and means extending through the table top to raise the bottom of the mould and hinge back the sides and ends. The ejecting means, shown in the raised position, consists of vertically reciprocable uprights 5 actuated in unison by a treadle 8 underneath the table 1. Each upright 5 carries, by means of cross-heads 9, a pair of depending side arms 10 which reciprocate on the edges of the table 1. The sides and ends of the mould are formed by pairs of angle irons, respectively 19, 19a hinged at 17, 18 to brackets 16, 18a which are attached to the outer sides of base members 14, 14a forming part of the supporting table 1. The sides and ends carry groove-forming strips 24. The bottom of the mould is formed by a palette 13, Fig. 4, located on the cross-heads 9 by dowels 12. In the moulding position with the uprights 5 lowered, the palette 13 rests on the base members 14, 14a and the mould sides 19, 19a are closed inwards on their hinges 17, 18. Rods 28 connecting the horizontal flanges of mould ends 19a to brackets 30 on the uprights 5 ensure that the ends are hinged down tightly. Interengaging extensions 22, 22a on the sides and ends respectively ensure that they hinge outwardly and inwardly in unison. Pins fixed to bars 34 are normally urged forwards by springs 39 to project through holes in the mould sides 19 into the moulding space. After the material has been cast the pins are withdrawn by pulling on handles 36 attached to the bars 34. A frame 43, arranged to slide on the table top 1 is provided at one side with a hand grip 42 and engages at the other side with handles 36 (not shown) remote from the operator thus enabling him to withdraw both sets of pins 32 from one side of the table. As the members 5 rise to eject the moulded article, the side arms 10 engage the horizontal flanges of the mould sides 19 and tip these up. The ejected article is then removed on its palette 13. Runners for a strickle Fig. 3 (not shown) are provided.
