Abstract: 911,250. Coat collars. BRITTON & CO. Ltd., ERIC. Dec. 11, 1959 [Dec. 30, 1958; Aug. 14, 1959], Nos. 41965/58 and 27882/59. Class 141. [Also in Group VIII] A laminated material suitable for making the stiffening components of garment collars comprises an under-collar layer, e.g. of Melton cloth, and a stiffening layer, e.g. of canvas, bonded thereto, the stiffening layer or both layers being cut on the bias and the stiffening layer having a yarn structure such that stretching produces a transverse curvature the concave side of which is arranged to be the under-collar layer side. The curvature is produced by warp and weft yarn twists which are in opposite senses to one another and the degree of which may be chosen to produce the degree of curvature required. The stiffening layer or both layers may be impregnated with thermoplastic adhesive and the layers adhered together with heat and pressure. Sheet material so prepared is cut into strips of widths required for collars and the strips are reeled under tension with their concave sides inwards, the reeling preserving the transverse curvature and also producing a desirable longitudinal curvature. The bias fabric may be produced by cutting a tubular fabric helically, but where strips, bias cut from flat fabric, are joined by sewing or adhesive, the layers are so chosen that the joins are concealed between the layers. In the Figure, collar components are marked for cutting from a strip very little wider than the components themselves. One of the Provisional Specifications describes under-collar and stiffening layers which (i) are bonded together only immediately before use, (ii) are bonded only in discrete areas or (iii) do not contain twisted yarns and are not necessarily cut on the bias. The other Provisional Specification states that the undercollar layer may be of unwoven fabric.

A filter 1-4 comprises a displaceable piston 15, baissed by spring 17 against upstream pressure P1 and magnetically coupled to an alarm device which operates in response to movement of piston 15 by increasing differential pressure. Piston 15 carries a ferromagnetic head 19 which attracts magnet 20, through non-magnetic cover 11, when piston 15 is bearing on retaining ring 16, against the action of its leaf spring 21. Clogging of the filter elements 1 causes increased pressure drop which moves piston 15 downwards, spring 21 is then allowed to lift magnet 20 to close a contact 22 and trigger a visible or audible warning. The filter comprises lenticular filter elements 1 with pore size less than 10 microns stacked on tubular support 3. Liquid enters union 5, passes through elements 1 and holes 6 into support 3 and leaves union 7. Nut 9 retains elements 1 on tube 3, and the elements are replaced by detaching cover 11.

For use as a clothes or hair dryer the cover plate 3 is raised to its horizontal open position, clothes supporting rails being provided as shown, and a curtain being suspended from a rail 27 around the edge of plate 3. This curtain may be folded away in channels provided in back plate 1 when it is not in use. The fan may be used alone or with one or more heating elements and a thermostat may be provided. In an alternative arrangement the motor, blower and heating element are mounted at the bottom of the back plate so that heated air is blown upwards.

[Also in Division B4] In order to compensate for variations in the dimensions of record cards caused by fluctuations in humidity, a hygrometer 3 selects one of a number of timing pulse trains occurring at slightly different time intervals in accordance with the prevailing humidity. The timing pulse trains are generated by photo-cells A2, B2, C2 co-operating with concentric sets of apertures 6 in a disc 5 which rotates in synchronism with the card feed, and the selected pulse train is used to gate the signals from a sensing station or to control a punching machine. A delay device 4 allows the cards time to adjust themselves to changes in humidity before the corresponding timing pulse train is selected.

Abstract: 1,268,657. Recording and playback of television signals. SANYO ELECTRIC CO. Ltd. 29 Aug., 1969 [14 Sept., 1968 (2)], No. 43130/69. Heading G5R. A helical-scan video tape recorder has a facility for still reproduction, during which the capstan 7 is disconnected from the driving means, the tape T is held stationary between the capstan 7 and a pinch roller 13, and the position of the tape T on the guide drums 3, 4 is adjusted to preserve a suitable scanning relationship between the tape and the rotating head (5, Figs. 6 and 7, not shown). As shown, for normal playback the capstan flywheel 12 is driven by means of wheels 8, 10. For slowmotion reproduction (Fig. 2, not shown), movement of a slide 56, and hence of a lever 14, causes the normal drive train 8, 10 to be replaced by a train 9, 15, 19, 18, 22 and a pushrod 61 to rotate a member 66 which by means of a screw (68, Figs. 6 and 7) moving in a fixed nut (69) raises a tape guide 67 to adjust the path of the tape T round the guide drums 3, 4. For still reproduction, a lever 40 is then rotated (Fig. 3), so that an arm 27 withdraws the drive train from the flywheel 12 and a wheel 45 engages the flywheel to permit fine manual adjustment of the longitudinal position of the tape by means of a knob 46. Tape tension is maintained by conventional braking and guiding means or by the application of torque to the take-up hub 1 through an idler wheel 82.

In an arrangement for measuring the rolling pressure in a rolling mill holes 7 (Fig. 1) are bored in the rolling mill stand 6 and one or more transducers are inserted in each hole the transducers providing an electrical output proportional to the stresses on the walls of said holes. The transducer may be of the kind described in Specification 1, 022, 178. In Fig. 3 (not shown) the transducer is of generally cylindrical form and comprises four cores 9 situated respectively at the four corners of a rectangular plane normal to the longitudinal axes of the cores. Each core has a winding 10 and diagonally opposite windings are connected in pairs, one pair being connected to an A. C. supply while the other pair emit electrical output signals which vary in magnitude with the mechanical stresses on the hole walls which stresses are communicated to the cores 9. There may be several transducers distributed along the length of each hole, Fig. 2 (not shown), thereby providing a measure of the pressure distribution on roller 2, which is communicated through sets of intermediate support rollers 3, 4, 5 to the rolling stand, and the electrical output is measured by a measuring device (not shown). All the outputs may be summed thereby providing a measure of the total rolling pressure. The axes of the holes are preferably parallel to the axes of the rollers. Instead of the transducers described, resistance strain gauge transducers may be glued in the holes.

Abstract: 948,360. Rolling. MORGAN CONSTRUCTION CO. Dec. 16, 1960 [Dec. 17, 1959], No. 43450/60. Heading B3M. [Also in Division G3]  In a loop thrower for a rolling mill, an actuator 26, Fig. 1, for the arm 19 carrying the tensioning roller 21 is initially moved transversely to the pass line with high pressure for rapid loop formation and then actuated with a low pressure for control of the formed loop. In an example of a pneumatically-operated system for providing high and low pressure, solenoid-actuated valves are operated from photo-cells detecting the presence of the rolled bar at the stands preceding and following the loop thrower. The system is initially actuated at high pressure when the work reaches the following stand and then drops to a low pressure under the control of a time delay circuit. Detection of the tail end of the work just before it leaves the preceding stand reverses the actuator 26 to lower the roller 21.
