Title: Improvements in or relating to a device for joining fabric strips
IPC: B29C65/48
Filed: 1968-12-19
Abstract: 1,205,510. Seaming non-metallic sheet material. SEMPERIT OSTERREICHISCH AMERIKANISCHE GUMMIWERKE A.G. 19 Dec., 1968 [20 Dec., 1967], No. 60298/68. Heading B5K. A device for joining marginally overlapping strips 16 of a self-adherent material, e.g. rubberized fabric, comprises a pivotable flap 4 having a porous surface 12 to which suction can be applied to hold a cut-off strip 3 at the output of a measuring beam 1 having cutting and clamping means, conveyer belt 9 on which the strips are deposited, and means to press the overlapped strips 16 into close contact, the pivotal axis of the flap 4 and the belt 9 being parallel to the cut edge of the strip 3. As shown, the cut-off strip 3 remains adhering to the uncut fabric 2 and hangs in front of the flap 4 with the cut line 5 at the top thereof. When the clamp closes before the next cutting operation, pistons 6 are moved forwards to open flaps 7 so that a space 8 beneath the belt 9 is connected to the hollow interior 10 of the flap 4 so that suction, which is constantly maintained under the perforated belt 9 by fans 11, is applied to the flap interior 10. The flaps 7 bear on the flap 4 which is pivoted forward about an axis 13 parallel to the strip 3 which is then peeled off by a bar 14 and deposited on the stationary belt 9 so that one edge thereof overlaps slightly the trailing edge of a preceding strip 16. When the piston stroke is completed, the flaps 7 close and the strip 3 is freed from the flap 4 and sticks to the belt 9. The piston 6 is reversed so that the flap 4 returns upwards and, simultaneously, the belt 9 is moved forward an increment. A roller 17 applies pressure to effect joining of the strips. To precisely determine the overlap, an accurate braking device 18 for the belt 9 is provided and is controlled by each strip by switches 19 on a slide 20.

Title: Method and means for compensating thermal lensing in a laser system
IPC: H01S3/00
Filed: 1970-12-31
Abstract: 1284530 Lasers UNION CARBIDE CORP 31 Dec 1970 [11 Feb 1970] 61943/70 Heading HlC Distortion of a laser beam due to temperature variations in the active medium (thermal lensing) is compensated by passing the beam through a material having inverse temperature variations. In Fig. 1, an annular laser rod 10 is pumped by a helical flash-tube; the rod is surface cooled, and is thus cooler at its inner and outer surfaces than elsewhere. The convergent beam B 1 whichis caused by the temperature gradient in the rod passes to an annular disc-like body 15 which is r.f. heated at its inner and outer surfaces by conductive layers thereon. An r.f, coil surrounds the disc, and the outer conductive layer is thin enough to allow some r.f. penetration to the inner layer. A telescope 17 expands the diameter of the compensated beam B2

Title: Ejector for damaged container caps
IPC: B07C5/06
Filed: 1970-12-31
Abstract: 1276072 Gauging and sorting ANCHOR HOCKING CORP 31 Dec 1970 [4 May 1970] 62057/70 Heading G1M A feed chute for container caps includes a go/no go gauge 4 which allows correct caps to pass but retains improperly formed caps, a pneumatic piston-cylinder unit 5 for moving the gauge out of the chute when it captures an improperly formed cap and a pneumatic piston-cylinder unit 9 for pushing the imperfect cap from the gauge. Sensors 7 and 8 are provided for sensing caps either side of the gauge and the absence of caps at sensor 8 closes a relay 34 which operates a solenoid 35 which in turn operates a control valve 37 to actuate pneumatic unit 5 and push the gauge 4 from the chute. When the piston 12 of unit 5 reaches its fully extended position it operates a puff valve 40 which sends a puff of air to an impulse relay 42 and control valve 43 of pneumatic unit 9 which causes piston 10 to be extended to reject the imperfect container from gauge 4. When piston 10 reaches its extended position it operates puff valve 45 which causes control valve 43 to retract piston 10. When piston 10 reaches its fully retracted position it engages puff valve 46 which causes control valve 37 to retract the piston of unit 5. When the gauge moves out of the chute a member 27 is caused to engage the caps upstream of the gauge by means of a cam on the gauge Fig.5 (not shown) to prevent caps reaching the gauging position during rejection of an imperfect cap.

Title: Heta-selable antistatic polypropylene films
IPC: C08J5/18
Filed: 1978-09-19
Abstract: An oriented heat-sealable antistatic polypropylene film is manufactured by applying to one or both surfaces of a base polypropylene film, preferably by co-extrusion, a layer of a heat-sealable olefinic polymer (for example, a predominantly linear random copolymer of ethylene with butene-1) containing between 0.2 and 10% by weight of an anionic hydrocarbyl (preferably long chain alkyl) sulphonate.

Title: Improvements in or relating to sputtering
IPC: C23C14/35
Filed: 1979-03-12
Abstract: The invention describes an electrode assembly for use in a sputtering apparatus.

Title: A Load-dependent Air Pressure Regulator for Vehicle Brakes
IPC: B60T8/18
Filed: 1980-06-06
Abstract: An air pressure regulator for vehicle brakes 13 has a drive piston 4 and a reaction piston 5 interconnected through a lever 6 whose fulcrum 7 is movable in accordance with a load on the vehicle. Piston 4 is operable by control air from a pedal valve 11. Piston 5 is urged upwardly by a brake pressure in a chamber 14 which communicates with the brakes 13, and urged downwardly, to open an inlet valve 15, by the lever 6 and an intermediate pressure in chambers 18, 23 the intermediate pressure being determined by a device 19 having a valve 25 controlled by a piston 21 which is responsive to the control air pressure from the pedal valve 11, and also to an adjustable spring 22. Below a predetermined control pressure level, set by the spring 22, valve 25 is open and a piston 5 is urged downwards to open valve 15 and pass air directly to the brakes 13. Above this pressure level the position of the piston 5 and valve 15 are largely dependent on vehicle loading, as reflected by the position of fulcrum 7. <IMAGE>
