Title: Methods and apparatuses for joining together parts of foam plastics
IPC: B29C65/02
Filed: 1973-12-05
Abstract: 1423277 Securing lids to containers TETRA PAK DEVELOPPMENT SA 5 Dec 1973 [8 Dec 1972] 56438/73 Heading B8C [Also in Division B5] A foam plastics closure panel 38 is joined to a filled container (40), Fig. 3 (not shown), by heating a portion of the panel 38 by heating jaws 39 so that it melts, while the container (40) is maintained at room or ambient temperature, and joining the panel 38 and the container (40) whereby the surface portion of the container (40) which is brought into contact with the molten portion of the panel 38 rapidly melts and the container (40) functions as heat dissipating means to provide rapid hardening of the molten portions. As shown, a mould 11 is movably attached to a vertically reciprocable machine element 10 and comprises an inverted cup-shaped means 12 having an inwardly directed shoulder 14 with an annular recess 15 and a coolant channel 16. A circular section stem 13 extends upwardly from the means 12 and has a widened portion 17 movable in a bore 19 in the element 10. Downward movement of the means 12 is limited by engagement of the portion 17 with a shoulder 42 and upward movement by engagement of the means 12 with a collar 43 on the element 10. A plug 20 closes the upper end of the bore 19 and compressed air can be supplied to the space between the portion 17 and the plug 20 through a channel 25. A suction plate 28 is secured to a stem 44 extending through a bore 41 of the stem 13 and is urged downwardly by a spring 31. Suction is produced through an opening 30 in the plate surface by connection of a channel 29 to a suction source. A clamping device 34 is mounted inside the means 12 and comprises a number of elements each having a downwardly directed flange 35 and a flange 36 acted on by a spring 37. In operation, a panel 38 is placed on the plate 28 so that its edges bear against the shoulder 14. Heating jaws 39, Fig. 2, are moved inwardly into contact with the edge of the panel 38 to heat this edge, the container (40) remaining unheated. The jaws 39 are removed and the element 10 is lowered so that the panel 38 engages the upper edge of the container (40). Upon continued downward movement of the element 10, the plate 28 is urged into the means 12 against the spring 31. This movement may be impeded slightly by supplying compressed air through the channel 25. The lower edge of the means 12 bends the edges of the panel 38 downwardly. The plate 28 engages the flanges 36 and tilts the device 34 so that the flanges 35 press the edges of the panel 38 against the cool container (40) to effect joining, Fig. 3 (not shown).

Title: Treatment of textile materials
IPC: D06M11/40
Filed: 1970-11-28
Abstract: 1388264 Hot mercerising and resin impregnation C DUCKWORTH 24 Feb 1972 [28 Nov 1970] 56660/70 Heading D1P Cellulosic textiles are impregnated with a crease proofing resin after being subjected to a "hot" mercerisation process which involves treating the textile with caustic soda at elevated temperatures between 25‹C and the boiling point of the system e.g. for not more than 10 seconds and then cooling the textile to below 25‹C at a stage between impregnation and controlled tension washing to remove the caustic soda. The "hot" mercerisation may be combined with scouring by including a con current steaming step. The resin may be a polyfunctional, monomeric heterocyclic N- methylol compound which may be padded on to the "hot" mercerised textile to a pick up of 11.2% (calculated as commercial product) and heat dry cured at 160‹C for 3 minutes, a magnesium chloride catalyst being used. The process improves the crease recovery properties of the textile. The textile may be in the form of yarn, or woven, non-woven or knitted fabrics. Cotton or linen, and blends of these with rayon and with polyester may be used. The fabric may be bleached or dyed between "hot" mercerising and resin impregnation, and may be calendered, embossed or showerproofed concurrently with or after resin impregnation.

Title: Hydraulic Clamping Heads
IPC: E02D13/10
Filed: 1966-12-19
Abstract: 1,175,520. Clamps; remotely controlled fastenings; pile driving. ZAKLADY SPRZETU BUDOWLANEGO NR2 SOLEC KUJAWSKI. 19 Dec., 1966 [20 Dec., 1965], No. 56803/66. Headings E1H; E2A and E2B. [Also in Division F1] A hydraulic clamping head comprises which may be used for driving and withdrawing piles a clamping jaw 14 actuatable by a first piston 11 reciprocably mounted in a first cylinder C, a second piston 18 reciprocably mounted in a second cylinder B communicating with the first cylinder C, and a third piston 17 linked to the second piston 18 and reciprocably mounted in a third cylinder A, the third piston 17 having a greater diameter than the second piston 18, the arrangement being such that in use, fluid supplied at one pressure to the first and second cylinders imparts a first clamping action to the jaw 14, whereafter fluid supplied at a higher pressure raises the pressure in the third cylinder A to cause displacement of the third piston whereby fluid pressure in the second and first cylinders is increased to impart a final clamping action to the clamping jaw 14. As shown, pressure medium is applied through a pipe 7 to valve chambers E and F to close off the pipe 19 to a chamber E and to close off a chamber F to cylinder B, and to open valve 10 to apply initial clamping pressure to piston 11. When fluid is supplied at the higher pressure, valve 15 opens and the pressure in cylinder A increases to move piston 17. Movement of the latter increases the pressure in chamber C which closes valve 10 and applies final clamping pressure on piston 11. The clamping action is removed by applying the pressure medium to pipe 19 and exhausting the system through pipe 7.

Title: Honeycomb materials
Inventor: WHITE DESMOND DEVERELL
IPC: B31D3/02
Filed: 1966-12-29
Abstract: 1,216,469. Honeycomb core material. DUFAYLITE DEVELOPMENTS Ltd. 29 Dec., 1967 [29 Dec., 1966], No. 68081/66. Heading B5N. A method of producing structural honeycomb material from flexible sheet material, e.g. chipboard, in the form of one or two continuous webs comprises piling up sheets of the flexible material derived from the web or webs to form a block of layers of the material, or winding the continuous web or webs to form blocks of layers of the material on a rotary former, and applying to the material parallel bands of adhesive so positioned that the bands which are to join one pair of contacting faces of the layers are staggered to lie between the bands which are to join the next succeeding and next preceding pairs of adjacent faces of the layers, said adhesive being applied to the material whilst it is exposed on the block or blocks or before it is fed thereto, the application of the adhesive to the material of the web or webs being omitted at regular intervals so that the block or blocks obtained is/are in the form of a series of subsidiary blocks which are unjoined by adhesive. The adhesive may be applied to one or both faces of each layer and an adhesive-free layer may be fed between each pair of adhesive coated layers. Alternatively the adhesive is applied by an intermittently operative applicator. The flexible material may be fed from a roll and cut to form the layers, the adhesive being applied before cutting. The adhesive bands may be located so that the cells of the honeycomb material are kite-shaped. When the winding method is used one or two webs of flexible material may be used and 2, 4 or more blocks may be formed on the rotary former, the blocks being removed, cut, and consolidated by pressing. In one method of forming the material, Fig. 4, a web of flexible material from a roll 53 is coated with bands of adhesive by a roller 54 and joined at a roller 55 with a similar, but adhesive-free web, the pair of webs is then coated with bands of adhesive by a roller 56 before winding on a rotary former 51. To provide the adhesive-free intervals, the backing roll 57 is moved away from the roller 56 at intervals. The material may be used as a separator in packaging.

Title: Improvements in or relating to machines for filling containers with liquid
Inventor: PHIPPS ROBERT ELLSWORTH
IPC: B65B7/28
Filed: 1969-12-18
Abstract: 1,235,057. Capping and filling containers; feeding cups; endless conveyers for containers; Closing containers. SWEETHEART PLASTICS Inc. 18 Dec., 1969, No. 61802/69. Headings B8A, B8C, B8S and B8T. A machine for filling and capping containers has a conveyer passing (a) a container supplying station 34, Fig. 1, (b) a filling station 36, (c) a capping station 38, and (d) a cap supplying station 40. The containers are then transferred by conveyer 44 to an exit conveyer 46. The containers C, Fig. 1, are transported in a conveyer 26 comprising two endless bands 74 carrying plates 66 with holes to receive the containers. Container supply device.-The conveyer 26 picks up containers from the container dispensing device 34 which has a container hopper in which the containers are held by two pairs of arms 124 and 136 (see Fig. 7, where only one arm of each pair is shown). Arms 124 grip the lowermost container in the hopper, and arms 136 grip the penultimate container in the hopper. The containers are discharged by arms 124 swinging back about pivot 126 so that the lowermost container is no longer supported, the rest of the containers in the hopper being supported by arms 136. Member 138 on arm 136 then moves downwards as a result of cam action and displaces the lowermost container by acting on the container rim. The arms 124 then return to their original position and arms 136 swing outwards and back to again grip the new penultimate container. The containers thus dispensed are held in holes in plates 66 on conveyer 26, Fig. 1, and are transported by intermittent action until they are stationary under filling nozzle 36. Pumps then force liquid from liquid storage tank 201 through piping 199 and out of the filler nozzle. Capping and cap supply.-The conveyer then transports the containers to cap applying mechanism 38 which comprises capping tools (256), (Fig. 15, not shown), supported on bar (254). The caps are supplied from cap hopper 40 which operates in a similar manner to the container hopper 34. The caps from the hopper fall on to recesses 210, Fig. 11 and are slid by pusher 216 along grooves (222), Fig. 10 (not shown), until they coincide with holes 214. The cap applying tool forces the caps through hole 214 into the tops of the containers. Container transfer.-At the end of conveyer 26 the containers are lifted out of the conveyer pockets and slide on to a plate where they are conveyed by a transfer conveyer 44 to exit conveyer 46. The transfer conveyer comprises two wiper bars 370, Fig. 17, which are attached to endless chains 326, Fig. 1. The wiper bars are attached to spindles 332 and 330 and pivoted so that wheel 340 always engages guide rails 350, 352. The guide rail has a cammed surface 360 at its far end so that the wipers on reaching this part of the conveyer swing backwards to disengage from the containers when they are on the exit conveyer 46. United States Specifications 3,165,233 and 3,100,513 are referred to.

Title: Mechanical toggle and fluid actuated ram for powder compacting press
IPC: B30B1/10
Filed: 1979-02-28
Abstract: A method of sealing a tube of flexible thermoplastics material by welding in which opposite sides of the tube are pressed flat between two jaws. The flattened tube thus has two opposed flat walls which have inner faces in contact, and these flat walls are connected at two opposite edges by folds caused by the flattening of the tube. The jaws are maintained a fixed distance apart, and one is rapidly reciprocated along its longitudinal direction by a vibrator, relatively to the other jaw. This causes the contacting flat walls to rub and become so heated by friction that the contacting plastics faces melt. These molten areas unite in a weld when reciprocation of the jaw is stopped and the plastics cools.

Title: Testing pneumatic brakes
IPC: B60T17/22
Filed: 1979-04-11
Abstract: When testing the efficiency of a pneumatic braking system (e.g. for a power guillotine) it is sometimes desired to measure the time which elapses between the venting of the pneumatic system and the instant when the machine comes to a halt. In order to make this measurement it is necessary to detect the exact instant when the pneumatic system is vented; this instant not normally being the same as the instant when the brake actuating sequence is commenced. This is because there may be a delay between the time when, for example, an emergency stop button is pressed and the time when this results in a pneumatic venting valve being opened. In accordance with the invention the instant when the pneumatic system is operated is detected by a microphone 80 connected to a sensing circuit 81, 82 so as to detect the noise produced by the venting of the pneumatic system 7, 8, 9, 10. <IMAGE>
