Abstract: 1334565 Sealing strips INDUSTRIE-EN HANDELSONDERNEMING ELTON NV 30 Sept 1971 [10 June 1971] 45552/71 Heading E1J [Also in Division F2] The arrowhead-shaped foot 8 of a resilient draught strip 5 (rubber or plastics) is forced into a groove 9 in a lath 2 of stiffer material (metal, wood or plastics) by means of a roller 6 whose axis is perpendicular to the plane of symmetry of foot 8 and lath groove 9. The lath 2 and strip 5 are guided as they each advance, the former by a guide track 1, and the latter by a guide track (4, Fig 1 not shown) inclined, in a vertical plane, to the guide track 1 and having a V-shaped cross-section with the apex pointing towards the guide track 1. The speed of the strip engaging roller 6 is at least equal to the speed at which the lath is advanced by a roller 3, and is preferably greater so that lengthwise compression of the strip 5 in the groove 9 is obtained. The roller 6 is vertically adjustable. The groove 9 may be completely open at the top or partially closed. In either case part of the foot is in transverse compression.

Abstract: 1332181 Refrigerating AIR PRODUCTS & CHEMICALS Inc 25 Sept 1970 [11 Dec 1969] 45803/70 Heading F4H [Also in Division A5] A device 18 for directing a jet of cryogenic fluid upon skin tissue comprises a nozzle 36 and means for cooling gas which is at a high pressure to a cryogenic temperature. The gas on entering the device through an attachment 54 is split into two streams, the first of which passes through a helical coil 49 of finned tube wound on a mandrel 42, and into a chamber 52 via a tip 50 which permits Joule-Thompson expansion of the gas and the consequent lowering of its temperature. The first gas stream in the helical coil on the mandrel is then precooled by heat transfer with the countercurrent passage of the expanded gas towards a vent 70 so that the fluid from the Joule-Thompson expansion is further reduced in temperature to a liquid-vapour mixture which is cold enough to liquefy by heat exchange the second stream of gas which passes through a helical coil 57 and then through a tube 58 from which it impinges the surface of the skin. The device is thermally insulated with material 72 such as extended polyurethane foam. The flow of gas from a high pressure cylinder (10) Fig. 1 (not shown) is regulated by means of a pressure reducing valve (20), downstream of which is a bed (22) of adsorbent material which removes impurities which may solidify and obstruct the heat exchange tubes. A further valve 24 which is electrically controlled is positioned to block the flow of gas to the probe, a light (30) across the electrical leads to the valve, indicating the open position of the valve.

A roll-type planishing machine includes groups of rolls 2 and 4 mounted in upper and lower frames 1 and 3 respectively, the frames being urged together by fluid operated jacks 7 which act on extensions of the frame 3 in stirrups 5, and being balanced by jacks 18. The jacks 7 are supplied with fluid from cylinders (11), (Fig. 3, not shown), whose rods (12) are attached by plates (26) to the cylinders of jacks (17). The piston rods (13) of these jacks (17) are threaded and are each rotatable through gearing (14) by motors (15). Rotation of the rods (13) causes them to move vertically and to effect vertical movement of the cylinders (17) and hence the piston rods (12). The jacks 7 are thus pressurized. For preliminary adjustment of the machine the motors (15) are operated to move the upper frame 1 vertically. By coupling together the motors (15) at (16) the screws (13) are rotated in opposite senses and cause tilting of the frame 1 about an axis parallel to those of the rolls. The motors (15) can be operated during planishing but normally the fluid pressure supply to the jacks (17) is controlled to produce vertical movement of the frame 1. Photo-electric cells at the entrance and exit of the machine sense the presence of a workpiece and, together with a timing device 23, control the opening and closing movements of the frames.

Abstract: 1523675 Injection moulding foamed articles having an unfoamed skin EX-CELL-O CORP 11 Nov 1976 46990/76 Heading B5A An article having an unfoamed skin of plastics material and a foamed interior of the same material, is made by sequentially injecting unfoamed, foamed and then further unfoamed material into a mould 45, from an injection chamber 47 into which the foamed and unfoamed material have been sequentially delivered, for the foamed material to at least partially foam in the chamber 47, by a single extruder 10 which is provided at its downstream end with an intermittently operable means 11, 19, 18, for injecting a liquid or gaseous foaming agent, e.g. nitrogen, into the material at one or more locations around or along the extruder barrel. The delivery of the material into the chamber 47 and the injection, are alternately effected with an injection passage 60 respectively closed and opened by an hydraulically operated valve 64, and the delivery and reverse flow to the extruder during injection are respectively permitted and prevented by a check valve 25. The extruder may also be provided with means 22, 21, 20 for injecting a colour additive into the material, and with a static mixer 16 intermediate the extruder and injection chamber 47. The operation of the apparatus is controlled from movement of the piston 35, either via a linear transducer developing a voltage proportional to the movement or, as described, via limit switches 66, 68, 70, 72, which are adjustable to alter the amount of unfoamed, and foamed material. Delivery of unfoamed material from the extruder into the chamber 47 is effected, with the valve 64 closed, against a back pressure on cylinder 35 set by an adjustable relief valve 80 in the hydraulic circuitry to the cylinder 35, thereby controlling the amount of foaming of the material after delivery of foamed material is commenced when both limit switches 66 and 68 are actuated to cause operation of the injection means 11, 19, 18. Delivery of foamed material is terminated when limit switch 70 is initiated to deactuate the injection means 11, 19, 18, and delivery of unfoamed material then continues until limit switch 72 is actuated to terminate operation of the extruder and, with valve 64 open, to initiate injection, optionally after a delay to permit hardening of the skin of the unfoamed material, by delivery of hydraulic fluid to the actuating cylinder of piston 35, via an adjustable valve 77, until switch 66 is actuated to also close valve 64.

In a synchronizing arrangement for a receiver in a time division multiplex pulse transmission system, the incoming pulses are supplied via a regenerator. RV to a shift register SR. The synchronizing signal consists of.alternate binary 1 and binary 0 in successive frames and during the synchronizing period the appropriate stage (K1) of the register is interrogated by means of a. pulse applied to line S to see if it contains the correct signal at the expected time. When a binary 1 is present at stage KI and coincides with a pulse on line S a bistable device KI is set via AND gate Ud1. during the next synchronizing period the signal at stage 1 should be binary 0 and if this is so an output from bi-stable circuit, KI is passed via the INHIBIT gate Jnh and AND gate Ud2 to set a bistable device KII. Thus a binary counter Z is switched via an AND gate UD3 to its first position and at the same time a signal on line RS resets the bi-stable circuits. Similarly, after each pair of frames the counter Z is stepped to its next position and at its final, i.e. eighth position, a signal is passed via AND gate UDZ to set the channel distributer into operation and it remains in operation as long as the synchronizing signals appear at the correct time and hold the counter Z in its final position. If the correct synchronizing signal does not appear at the expected time the counter Z is switched back one or more steps by the signal on line S. To ensure that only a repeated number of successive false synchronizing signals can cause switching back of the counter Z it may be in the form of a forwardsbackwards counter arranged to count one step forward for a correct signal and two steps backward for an incorrect signal, a new synchronizing sequence being initiated only if the zero position is reached.
