Title: Improvements in or relating to Material Feed Apparatus
IPC: B21D43/09
Filed: 1967-08-10
Abstract: 1,176,963. Metal strip feeds. MAGNETIC METALS CO. 10 Aug., 1967 [19 Aug., 1966], No. 36831/67. Heading B3W. A punching press has feed means which are driven from the main shaft of the press, the drive means including a first shaft which rotates with uniform angular velocity through a complete revolution for each cycle of operation and drives a second shaft so that it has non- uniform angular velocity, the second shaft being connected to the input shaft of a further device which also has an output shaft, the input and output shafts being connected so that the output shaft rotates in response to rotation of the input shaft over a first predetermined portion of a revolution and then dwells during the remainder of that revolution. The metal strip is fed into the press by feed rolls of which one is intermittently driven and the other is spring-loaded against the driven roll. The take-off shaft of the press which makes one revolution for each cycle of the press drives an elliptical gear 136, Fig. 10, which meshes with a second elliptical gear 142. The shaft 133 of the second gear drives a shaft on which is eccentrically mounted a pinion 47. This pinion meshes with an idler gear 48 and an output gear 49 which dwells during part of the rotation of pinion 47. This part of the mechanism is fully described in Specification 1,097,480 (Division B3). In a modification the gear train 47, 48, 49 is replaced by a Geneva cam mechanism which is fully described in Specification 1,159,883. The elliptical gears are mounted in a casing, Fig. 8, on parallel shafts 132, 133. Also included in the casing are two circular gears 137, 143, each mounted on one of the shafts. The gears 136, 137 are mounted on a sleeve which is keyed to but slidable along the shaft 132. By moving a spacer 140 from the position shown in Fig. 8, to a position between the gear 136 and the adjacent wall of the casing, the gears 136, 142 are disengaged and the gears 137, 143 are engaged. The angular positions of the gears 136, 142 are such, in relation to the remainder of the mechanism shown in Fig. 10, that the angular velocity of gear 133 is at a minimum when it is at the midpoint of its angular range of motion throughout which the dwell of the output gear 49 occurs. The effect of the elliptical gears is to increase the dwell time of the output shaft from about 90 degrees, which is about the maximum which can be achieved with either of the previously disclosed constructions, to 180 degrees.

Title: Elution electrophoresis
IPC: G01N27/447
Filed: 1965-08-27
Abstract: <PICT:1043840/C6-C7/1> <PICT:1043840/C6-C7/2> Electro-phoretically deposited components formed on a membrane from a complex substance, are individually separated into pure components by immersing the membrane in a buffer solution and eluting the components electro phoretically which are drawn off into individual collecting zones. The coated membrane 10 of accylamide gel is first made by depositing the components from the complex mixture by applying the electric field across the face of the membrane, whereby the individual components are deposited in parallel zones or "streaks".  The coated membrane is mounted in a cell 14, Fig. 1. with electrodes 18, 20, the face of the membrane being pressed against a block 22 honeycombed with channels 24 Figs 1, 5, having vertical drain grooves 26.  Sponge blocks 32, 34 press the membrane 10, and a second membrane 30 against the block 22.  The eluted components are drawn off from their locations in the coated membrane and drain off downwards into individual pots 28.  The barrier membrane 30 prevents components from passing through, and drain grooves facing this membrane (similar to grooves 26) provide some convection flow of the buffer eluant. In modifications Fig. 7 (not shown), the pressure sponge blocks 32, 34 are replaced by bags of cellulose material which enclose the electrodes and press against the grid block 22.  The buffer eluant is pumped continuously so that anolyte and catholyte are mixed neutralizing any pH change.  In Fig. 9, (not shown), the pressure exerted on the coated diaphragm 10 is sufficient to cause the gel body to be forced into the channels 24.  The electrodes are frames of insulating material into the edges of which perforated or wire mesh stainless steel is embedded.

Title: Storage assemblies
IPC: B65G1/10
Filed: 1973-08-04
Abstract: 1450125 Storage system BAR PRODUCTIONS (BROMSGROVE) Ltd 22 Nov 1973 [4 Aug 1973]  37102/73 Heading A4T A storage system comprises a row of storage units A-C movable to open a gangway between any two adjacent units, sensor switches LF1, LR1 -LF3, LR3 on each unit arranged to be operated by feeler means F for engaging an adjacent unit, a central programmer P including selector switches SS1-1-SS1-7, manual means G for setting the selector switches to open a required gangway, and respective control circuits for operating motor control relays MF1-MF3 or MR1-MR3 of each unit to actuate one or more motors M to drive the unit in either a forward or reverse direction as required. Two fixed storage units DE are provided at the ends of the row. On setting the means G and actuating a start switch J, the selector switches corresponding to the units to be moved and the required direction are closed. Since each control circuit includes a respective said selector switch and sensor switch in series, a circuit in which the sensor switch is closed owing to the absence of engagement with an adjacent unit is thus activated, so that the appropriate motor control relay acts to shift the unit. Disengagement from the adjacent unit thus allows the sensor switch of the latter unit to close, enabling this unit to be moved if the corresponding selector switch is closed, and thus the units are shifted in turn until the required gangway is opened. Preferably time delay means are incorporated so that the units follow each other smoothly at a slight spacing, and an emergency stop button I is provided, along with overload switches L.

Filed: 1954-12-23
Abstract: 753,007. Strap fastenings. WHITING, J. R. STURGE-. Dec. 23, 1954, No. 37290/54. Addition to 719,818. Class 44. The fastening of the parent Specification is modified in that the speed of relative movement of the two main parts in the releasing direction under the force of the spring means is controlled by a buffer device which is automatically coupled into the operative position prior to such movement in the releasing direction. As shown, links 20, 20 of a main fastening part A to which a belt part is attached are connected together by a member 19 on which bears an abutment member 10 for a pair of springs 12 located between the member 10 and a compression block 2 which is slidable on guides 5 extending between the member 10 and a plunger block 1. Links 25, 25 of a second main part B to which another belt part is attached are connected together by the block 2 through pins 11 which are engaged in and disengaged from, slots on the links 20, as in the parent Specification. In order to control the relative movement of the parts A and B under the action of the springs 12, a plunger 3, slidable in a liquid-filled recess 3a in the block 1, engages in the block 2, in the non- released position of the parts A and B, above a spring-loaded block 4. During the releasing movement of the parts A and B, the block 4 rides past the plunger 3 and subsequently depresses the plunger as the part B is freed from the slots in the links 20 of the part A under the action of the springs 12.
Patent GB-1106832-A (GB)
Title: Process for the production of porous, self-adhesive tapes or sheets particularly plasters
IPC: C09J7/38
Filed: 1966-08-19
Abstract: A process for the production of porous, self-adhesive tapes or sheets, e.g. plaster dressings, comprises applying a layer of a solution or dispersion of a visco-elastic self-adhesive mass to an intermediate support having an adhesive-repellant surface, converting the same into a finely-vesicular condition by rapid evaporation at a raised temperature of the solvent or dispersion medium, and transferring the fully dried adhesive layer to a porous base by cooling it to room temperature and applying it to the porous base under pressure.  The intermediate support may comprise paper with a silicone coating or a steel band.  The porous base may comprise non-woven fabrics impregnated with hydrophobic material, e.g. a modified melamine resin, woven materials, or a polyurethane foam. The adhesive may comprise, e.g. polyacrylic esters or acrylic ester copolymers.  The adhesive is coated on the intermediate support and the rapid evaporation of the solvent or dispersion medium, by subjecting the support to a progressively increasing temperature, causes very small bubbles to form in the adhesive layer.  When the porous base is placed over the adhesive and after cooling to room temperature pressure is applied by calendering and the bubbles ruptured to form a micro-porous surface.  The assembly may be again heated to increase bonding before the intermediate support is stripped off. Quantitative examples are given.  A release coating may be applied to the uncoated side of the porous base.

Filed: 1963-09-24
Abstract: 1,090,296. Liquid indicators. DOBBIE McINNES Ltd. Sept. 8, 1964 [Sept, 24, 1963]. No. 37447/63. Heading G1H. In apparatus for measuring the hydrostatic head of a body of liquid for determining a ship's draught, or the depth, weight or volume of a liquid in a container, air under pressure is supplied to the lowest receiver 13 of a number of vertically spaced receivers 8-13, through a pipe 35, economizer 18 and tube 20. Air under pressure depresses the liquid level in receiver 13 until air bubbles through the opening 15A of the pipe 15, a pot 12 now being charged with air at a pressure which counterbalances the head of water above a datum 2 at the opening 15A of the pipe 15. The air finally escapes through pipe 16, a swan neck 17 and air-operated diaphragm valve 18 to atmosphere. A mercury thermometer is plugged by a plug 32 and socket 26, and the over-all head of water indicated on its scale. A water manometer 38 is connected to the pot 12 by a plug 33 and socket 31 which corresponds to the first scale marking below the mercury level and measures the relative hydrostatic head above the level Z in the pot 12. By adding the readings of manometers 37, 38 a measure of the ship's draught is obtained. In a modification Fig. 4 (not shown) similar apparatus is used for measuring the depth of liquid in a tank, in which case a series of receivers are located at different levels in a tank. In a further arrangement, nitrogen may be used instead of air.

Filed: 1963-09-25
Abstract: 984,784. Fluid-pressure brakes. ROBERT BOSCH G.m.b.H. Sept. 25, 1963 [Sept. 26, 1962], No. 37664/63. Heading F2F. A brake system for motor vehicles comprises a compressed-air main brake (foot brake) controllable by a main valve 6, Fig. 1, and a compressed-air auxiliary brake (hand brake) operable by an auxiliary valve 13, the brake cylinders 9, 15 of both brakes being operable on common wheel braking members. Both brakes have independent conduit systems 14<SP>1</SP>, 17 communicating with the chambers 27, 32, Fig. 2, of a selector valve device 16, the chambers being separated by a movable wall 28. The device 16 limits, with simultaneous operation of the valves 6, 13, the braking pressure rise of the auxiliary brake so that the combined braking pressure is not greater than the permissible safe maximum. As shown, the foot-brake system is constituted by a compressed air reservoir 3 supplied by a compressor 1 via a pressure regulator 2 front and rear brake cylinders 8, 9 and drivers valve 6. The hand-brake system includes the reservoir 3, drivers valve 13 and a spring- applied compressed-air released rear brake cylinder 15. The selector valve device 16, Fig. 2, controls by means of the diaphragm 28 and valve seat 24 the communication of compressed air, when the drivers' valve 13 is actuated, to the brake cylinder 15, so as to limit the summation of pressures, in the case of simultaneous actuation of both brakes, to that of the permissible safe maximum. The pressure in the foot brake system is communicated to the chamber 32 of the device 16 and acts against the spring 33 to hold the diaphragm 28 against the seat. If the pressure in that system is less than the permissible maximum the pressure in chamber 15 will be exhausted to allow the spring therein to apply the brake until the forces on the diaphragm 28 are balanced when it closes the seat 24. The brake cylinders 9, 15 and a modification of the selector valve device 16 are combined to form one unit in Fig. 4. The cylinder 9 comprises a chamber 119 fed with compressed air via connection 7 to apply the brake connected to the head 82 by means of piston 123 and rods 127, 81. The cylinder 15 comprises chamber 90 normally pressurized which when exhausted through connection 14 allows the spring 109 to act through piston 77, sleeve 75 and nut 79 on the head 82 to apply the brakes. The modified device 16 comprises a spring-loaded diaphragm 92 and valve seat 88.
