Title: Napping and finishing of cloths
IPC: D06Q1/06
Filed: 1975-12-31
Abstract: 1528020 Finishing fabrics COLORTEX SA 31 Dec 1975 [6 Feb 1975] 53320/75 Heading D1S Relieved surface portions are obtained on a cloth by applying a hardenable material to define each surface portion which it is desired to avoid raising in a napping operation, allowing the hardenable material to harden and thereafter performing the napping operation by napping means moving in a predetermined direction relative to the cloth to raise the nap from areas other than each surface portion, the width of each surface portion transverse to the napping direction being less than a predetermined value to avoid tearing the cloth. Prior to napping, e.g. by teazlers, the hardening agent, e.g. an acrylic resin, may be hardened by combination with an affixer additive, e.g. a melamine resin, and after napping the agent may be softened with a softener additive, e.g. a polyethylene emulsion. Treatment may be effected after washing the cloth after it has left the loom. After napping, the cloth is smoothed and sheared. Napping is effected over the whole surface of the cloth but the nap is raised only in the areas not treated with the hardening agent. Both surfaces of the cloth may be treated.

Title: Counting devices
IPC: G06M9/02
Filed: 1971-11-17
Abstract: 1349770 Counters CANYON RESEARCH CORP 17 Nov 1971 [20 Nov 1970] 53322/71 Heading G4D An apparatus for counting sheets, such as bank notes, in a stack comprises a reciprocating pusher 84 and a rotating finger 52 which cooperate to lift the edge of each sheet in succession, one for each rotation of a counting head 50 coupled to a register 30. The bank notes 22 rest on a base 70 below a clamp 42. The clamp 42 and the rotating head 50 can be raised by depressing a lever 44, initial depression of which disengages a clutch, and then switches off a drive motor, to stop the head rotating. The slack is positioned so that the pusher blade 84 rests on the edge of the slack as shown. The blade 84 is on the end of a toggle linkage 74, 76 which is alternately straightened and collapsed by a cam 124 and follower 100 as the head rotates. As the toggle straightens the blade 84 pushes the top sheet forming a loop 116; the finger 52 enters the loop and lifts the end of the sheet over the top of the head 50. When all the sheets have been counted a loop (266) on the underside of head 50 trips a switch (40) in the base 70 (Figs. 3, 6, not shown) to stop the motor. The register 30 can be set to zero by a button 182, or alternatively to a preset value in which case the counter counts down and stops when zero is reached. Counting speed is adjustable by varying the motor speed.

Abstract: 1495252 Compressors HALL-THERMOTANK PRODUCTS Ltd 19 Nov 1974 [19 Nov 1973 20 March 1974] 53666/73 and 12441/74 Addition to 1352699 Heading F4H In a process of gas compression as described in parent Specification wherein a rotary positive displacement compressor is employed, and liquid is injected into the compressor rotor clearance gaps which is the liquid phase of the gas or vapour being compressed, the liquid is injected in sufficient quantity to maintain the gas or vapour temperatures in the compressor close to the saturation temperatures of the gas or vapour being compressed. As shown in Fig. 2, the compressor 10 and its driving motor 3 are housed end-to-end in a common casing 4. The motor chamber 14, which is at the high pressure end of the compressor rotor, constitutes a discharge chamber for the compressor, the compressed vapour being delivered into the motor chamber 14 from the high pressure end of the compressor chamber through passages 5 in the partition 9. Since the liquid phase of the vapour being compressed is injected into the compressor chamber at D, the discharge into chamber 14 at 6 consists of a mixture of saturated vapour and liquid. The motor windings bathed in this discharge mixture are thus cooled by evaporation of liquid.

Abstract: 1,159,017. Vacuum switches; spark gaps. ALMANNA SVENSKA ELEKTRISKA A.B. 2 Dec., 1966 [3 Dec., 1965], No. 54081/66. Headings H1D and H1N. A vacuum switch for interrupting D.C. has a cathode 3 and an anode 2, the cathode being insulated 9 and the electrodes being relatively movable so that at the end of the movement the insulation 9 lies between the anode 2 and the cathode spot from which the plasma is ejected. Each of the electrodes is mounted by bellows 7, 13 for movement relative to the evacuated envelope 1; the electrodes are initially in enagement. To break the circuit electrode 3 is drawn downwards to separate it from electrode 2 to create an arc; electrode 2 is then moved to the left away from the cathode spot increasing the arc voltage. Lastly electrode 3 is moved upwards to bring the insulation 9 between the electrodes, increasing the arc voltage further until the arc is extinguished. For highly inductive circuits a resistor 14 may be connected in parallel with the vacuum switch the residual current being interrupted by a switch 18. The resistor may be shunted by a further switch 19 carrying the load current. In a modification (Fig. 2, not shown) electrode 3 is fixed and electrode performs rectilinear and rotational movement in response to rectilinear movement of an operating rod (25). Multiple series connected breaks may be employed (Figs. 3, 4, not shown). In another alternative (Fig. 5, not shown) the arc is transferred from the main anode (4) successively to a series of auxiliary anodes (50-55) connected through resistors (56-61) and arranged helically in the walls of the envelope (1). The resistors may be within the envelope (Fig. 7, not shown). The cathode 3 may be associated with an auxiliary electrode 80 an arc (83) being maintained between them by an auxiliary circuit; the assembly is then contained in an insulating shield 84. In another embodiment (Fig. 9, not shown) the cathode 3 is spring loaded in an insulating tube (9) while the anode is arcuate and arranged to be rotated away from the cathode by a rack and pinion (96, 95). Two such sets of electrodes may be mounted back to back (Fig. 10, not shown) when it is necessary to interrupt a D.C. of unknown polarity.

[Also in Division F1] A firing mechanism comprises a drum 8 rotatably mounted in a housing and having a charge receiving chamber 10 communicating with a gas port 32 and with a loading port 6 when the drum 8 is in a firing-fired and loading positions respectively. A firing pin 12 is provided in the drum 8 and in the fired position is biased such that a forward part thereof projects into the charge receiving chamber 10. The firing pin 12 has a cam follower 60 and the housing a cam 18 such that on the rotation of the drum in one direction the forward end of the firing pin 12 is withdrawn from the charge receiving chamber 10 by the time the drum reaches the loading position and a further rotation in the one direction the firing pin 12 is further withdrawn into the drum against its biasing means until the drum has turned through 360 degrees whence the firing pin 12 is released to fire the charge in the charge receiving chamber 10. In the construction shown the drum 8 is rotated by a knob 20. The cam 18 has two concave surface portions, to releasably hold the cam follower and hence the drum 8 in the firing-fired position and the loading position respectively (Figs. 3, 4, 6, not shown). The firing portion of the cam 18 comprises a straight portion parallel to the axis of the firing pin, a guide member being provided on the housing facing the straight portion such that the cam follower must move along the straight portion before the drum can be turned further in the one direction. In the firing-fired position the charge receiving chamber 10 communicates with the gas port 32 through smaller diameter bores 34.
