Title: Machine for closing or sealing multi-cellular wrappers
IPC: B65B11/50
Filed: 1946-01-28
Abstract: 607,796. Closing or sealing packages. NICOLLE, C. Jan. 28, 1946, No. 2696. Convention date, April 29, 1944. [Class 94(i)] A'machine for closing or sealing by pressure between two dies multi-cellular wrappers made of recessed strips or sheets of plastic materials includes a grate for supporting the wrappers or elements thereof as they are brought to or removed from the machine, the grate receding during the closing operation into grooves in the bottom die. In one form, the grate 1, Fig. 3, is separate from the pressure dies, and is placed manually between the dies after a recessed sheet 2 has been placed on it, the recesses filled and an upper sheet placed over the sheet 2, the recesses of the sheet 2 fitting into equivalent recesses in the lower die. The bars 11 of the grate.may be in alignment with perforated lines separating rows of recesses in the sheets. The dies 4, 6, Fig. 10, of the press are brought together to join the sheets over their flat portions. The adhesion is caused by pressure acting on glue or solvent previously placed on one of the sheets, and may be assisted by the application of heat. During the closing operation, the bars 11 of the grate recede into grooves 8 in the die 4 If adhesion is required over the areas of the sheets positioned over the grooves, the bars must be shaped to fill the grooves completely or be urged upwards by springs so as to present a continuous surface. On opening the press, the grate is released from the die 4 by means of springs or catches secured to the upper die or located inside the bottom die, whereby the finished package rests again on the grate and is removed manually from the machine. The grate may be stationary and form part of the press, and may be extended longitudinally from at least one side of the machine. In this case, the lower sheet may be placed on the grate and manually slid therealong to various positions where the operations of filling, and positioning the upper sheet can be performed, the package then being slid into position between the dies, where it is aligned by means of automatically-receding stops. After the closing operation, the lower die being movable, the package is slid out of the press along the grate to a cooling station. A coating block may be associated with the lower die, integral therewith or secured to the press plate supporting the die, the block having recesses corresponding to those in the lower sheet and grooves to accommodate the bars of the grate. Adhesive is then applied to a sheet on the block while a package is in the press, and as the closed package is removed from the press the package on the block is moved into the press and a fresh sheet placed on the block. The upper die may be movable instead of the lower, in which case the grate may be lowered into and raised out of the grooves in the lower die by means of a connection with the movable press plate carrying the die.

Filed: 1967-01-18
Abstract: 1,129,768. Image intensifying device. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 18 Jan., 1967 [20 Jan., 1966], No. 2701/67. Heading H4F. [Also in Division H1] An image intensifying tube device comprises a plurality of consecutive, optically coupled sections 2, 3 and 4, each having a photocathode, 2<SP>1</SP>, 3<SP>1</SP> and 4<SP>1</SP> respectively, and a phosphor screen 2<SP>11</SP>, 3<SP>11</SP> and 4<SP>11</SP> respectively. Cathode 21 and screen 4<SP>11</SP> are formed on the ends of the tube, and screen 2<SP>11</SP> and cathode 3<SP>1</SP> are formed on either side of a glass plate. Screen 3<SP>11</SP> and cathode 4<SP>1</SP> have a similar construction. The positive terminal of a 20 kV source is applied to screen 4<SP>11</SP> and to the screen/ cathode pairs 2<SP>11</SP>/3<SP>1</SP> and 3<SP>11</SP>/4<SP>1</SP> via respective current limiting resistors 5 and 6. The negative terminal of the source is connected to cathode 2<SP>1</SP> and to the screen/cathode pairs 2<SP>11</SP>/3<SP>1</SP> and 311/41 via respective thyristor switches 7 and 8, initially open. A light pulse is incedent on the cathode 2<SP>1</SP> from time t 1  to t 2  (see Fig. 2). With switches 7 and 8 open, the 30 kV appears across section 2 and if switch 7 is closed at time t 2  electrons will flow from cathode 2<SP>1</SP> to screen 2<SP>11</SP> for the period indicated at Fig. 2(2). The flow of electrons to screen 211 will cause the screen to brighten up to time t 2  and then decay. Closure of switch 7 transfers the 30 kV across section 3, when from time t 2  to t 3  when switch 8 is closed, the decaying brightness of the screen 211 causes a corresponding decaying flow of electrons from cathode 3<SP>1</SP> to screen 3<SP>11</SP>, as indicated shaded at Fig. 2(3). Integration of the impinging electrons on screen 311 causes it to brighten up to time t 3  and then decay. The closure of switch 8 transfers the 30 kV across section 4 and the decaying flow of electrons from cathode 4<SP>1</SP> shown shaded at Fig. 2(4) is integrated on screen 4<SP>11</SP> to produce a much intensified image. The screens 2<SP>11</SP>, 311 and 4<SP>11</SP> should have increasing retentivity.

Abstract: 1453821 Charging and tapping induction furnaces; furnace hearths ASEA AB 22 Jan 1974 [23 Jan 1973] 02960/74 Heading F4B [Also in Divisions C7 and H5] A furnace for reducing metal oxide comprising a closed substantially flat bottomed hearth 2, one or more substantially flat spirally wound induction coils 7 below the bottom of the furnace and arranged so as to produce ridges 10 in the molten metal surface, means 13 and 14 for feeding metal oxide material and carbonaceous material into the furnace and openings for remaining gases, metal and slag. The gases produced may be partially burnt above the melt and the remainder removed to a waste heat boiler by water-cooled pipes in a central dome 15 of the gas tight furnace cover. The rammed furnace bottom 2 may rest on water cooled mutually insulated metallic crossbars 5 of stainless steel tubes to reduce the load on the induction coil(s) 7 which may be in the form of water cooled copper "pancake coils" operating at 50-60 Hertz and a power input of 650 kW./m.<SP>2</SP> such that the melt is heated by induced electric currents and is exposed to maximum repulsion forces above the centre of the coil thereby forming ridges in the melt surface. The induction coil(s) together with magnetic yokes for shielding may be mounted on a trailer 9 containing an elevating device to permit removal of the coil(s) from the furnace. Slag may be removed via a gas or liquid cooled refractory nozzle in the centre of the bath or by reducing the electromagnetic repulsion forces at one end of the furnace by either increasing the coil spacing or the distance from the furnace bottom in this region thereby reducing the height of the melt ridge and allowing slag to leave via a tap hole in the furnace wall. In an embodiment, Fig. 4, oxide material is fluidized with gas from distributers 22a and blown into the furnace via shoots 20, 22 and slots 23, a high voltage electric field being applied at the slots to reduce dust losses from the furnace.

Title: Improvements relating to tanks for delivering measured quantities of liquid
Inventor: SMITH ARTHUR HENRY
IPC: G01F11/28
Filed: 1957-01-29
Abstract: 824,006. Delivering measured quantities of liquid. BENFORD Ltd. Jan. 29, 1958 [Jan. 29, 1957], No. 3060/57. Class 106(5) The cross-section of a measuring tank 12 for delivering water to a concrete mixer is tapered downwards so that any given quantity of water admitted to the tank produces a greater change in liquid level at the top than the bottom, thus maintaining the accuracy constant for large or small measured quantities, and the level to which the tank can be filled is adjustable by means of a vent pipe which can be set at different levels. As shown, the internal and external vent pipes 15, 16 are connected by a part 17 rotatable in a gland 18 and a sight glass 22 is calibrated to indicate to the operator the level at which to set the pipe 15. Water entering through a valve 27 rises in the tank until the end of the vent pipe is submerged and the rising pressure above the liquid level moves a diaphragm 33 so the valve 27 closes and prevents further admission of water. The contents of the tank can be discharged through a port 40 by movement to the right of a valve 35, the valve also having a neutral position, as shown, and a position connecting a mains inlet 39 to the valve 27. The Provisional Specification describes float means for operating the valve 27, the float being disposed in a chamber which is open to atmosphere and connected by a sleeve to a point near the bottom of the tank so that the rising pressure when the vent pipe is submerged will force water into the chamber.

Title: Improvements in or relating to motorised switch gear
Inventor: NEWBERY STANLEY
Filed: 1955-02-03
Abstract: 775,045. interrupters. NEWBERRY, Ltd., S. Feb. 3, 1956 [Feb. 3, 1955], No. 3190/55. Class 38(5)  In an electric motor-driven interrupter a contact carrying member 9 engages a laterally reciprocating member 6 in a double fulcrum comprising the knife edges 7. As a motor driven cam 3 rotates a lever 5 moves the reciprocating member 6 which carries along the member 9 until this engages one of thescrews 6b when it tilts about one of the knife edges so that a bridging contact 11 engages fixed contacts 13, 15 or 12, 14. Coil springs 10 provide a snap-action movement. On further rotation of the cam a second lever returns the member 6. The double fulcrum arrangement provides a "dwell" period when neither pair of fixed contacts is bridged. The "dwell" period may be varied by the cam arrangement which comprises two discs 3, 3a which are relatively rotatable on the shaft. A second contact carrying member and four more fixed contacts may be provided as is shown to provide a double-pole, double throw switch, and in this case the coil springs 10 connect the two members 9. The contact 11 fits loosely in the member 9, thus being self aligning, and the wiping action of the contacts on engagement provides "self cleaning."
