Title: Improvements in or relating to the continuous heat treatment and "hot dipping" of metal wire and apparatus therefor
IPC: C21D9/62
Filed: 1965-10-27
Abstract: <PICT:1121548/C6-C7/1> Metal e.g. steel wire 1 is continuously heat-treated and hot-dip metallized by first heating it in a reducing gas, such as hydrogen from cracked ammonia to at least 700 DEG C. to clean it, passing it through a molten lead bath 10, containing a percentage of zinc higher than 0.3 and below the solubility limit (4%) of zinc in lead, to emerge into air covered with a sheath of lead, and then passing the wire through a molten metal bath 13 in a separate tank to strip the wire of its lead sheath and subsequently cover it with a layer of the molten metal, such as zinc or aluminium. The reducing gas is preferably circulated through a muffle 15 as shown by arrows 16, 17, one end of which is immersed in the lead bath 10.  The wire may be heated by the Joule effect using another molten lead bath 9 through which the wire passes before entering the bath 10, lead baths being connected to an electrical supply 14 and the roller 4 guiding the wire between these baths being electrically insulated.  Alternatively the wire may be heated by an electrically heated oven see Figs. 2 to 4, (not shown) or by means of liquid or gaseous fuel.

Abstract: 1428138 Flock coated products NAIRN FLOORS LTD 1 Oct 1973 [3 Oct 1972] 45588/ 72 Heading B2E  A method of making a flocked product comprises applying a fluid binder to a substrate flocking fibres on to the binder, laying the fibres in a first part of the area of the surface in a predominant non-perpendicular direction while maintaining them substantially linear by rolling a stencil over and in contact with the product with no relatve movement at the zone of contact between the stencil and the product, laying the fibres in a second part of the area of the surface in a different predominant non- perpendicular orientation while maintaining them substantially linear by movement of a separate moveable orientation means contained in the stencil, the second area being the area of the surface in contact with the perforations in the stencil and hardening the binder. The orientation fibres within the area of the surface is usually such that substantially all the fibres lay in one direction, for example at an angle of less than 45 and usually less than 30 to the plane of the surface. The whole of the surface may be of areas having non-perpendicular orientation of the fibres but one or more areas having perpendicular orientation may also be present in the product. All the fibres on the surface may be first effected in one direction by brushing or other means and the stencil then rolled over the product, the fibres in parts only of the surface being reoriented by the orienting means within the stencil. The means for laying the fibres in the second part of the area of the surface may comprise a rotatable brush whose axis is parallel with the stencil and whose bristles extend to but not beyond the perforations where they are in contact with the product and which rotates faster than the stencil and in the same direction. The substrate may be of fibrous material such as a textile or paper and woven, knitted and non-woven fabrics from natural or synthetic fibres. Suitable binders are acrylic binders. vinyl chloride, homo- or copolymers and polyurethanes. They are generally applied from a solution or dispersion. Suitable flocking fibres are cotton, rayon, nylon, acrylic and polyester materials. They can be precision-cut fibres or ground fibres or mixtures of these. The flocking may be by a conventional electrostatic flocking process.

Title: Pendulum switches
IPC: B60R25/10
Filed: 1971-10-01
Abstract: 1369226 Transistor time delay switches EMDEKO INTERNATIONAL Inc 1 Oct 1971 [2 April 1971] 45787/71 Heading H3T [Also in Divisions G4 and H1] In a vehicle theft alarm (see Division G4) time delays are provided to enable the user to leave and re-enter the vehicle. On leaving the vehicle, the alarm is set by closing SW1 which enables C1 to charge via the base/emitter path of Q1, which action maintains Q2 non-conductive and thus enables C3 to charge via R7 and D1. This action maintains Q3 conductive and Q4 non-conductive so that the driver can leave the vehicle without setting off the alarm. After 15 seconds, closure of a pendulum switch SW3 by a person entering the vehicle or closure of switches SW4 or SW5 by opening a door or the boot, turns on Q2 and isolates the charging path for C3. After 6 seconds (time sufficient for the authorized user to disable the alarm, C3 and C4 will have ceased discharging through the base/emitter path of Q3 so that Q3 becomes non- conductive, turning on Q4 and operating the alarm relay RE1. Contacts SW2 allow C2 to discharge so that in 20 seconds Q2 will be turned off, allowing C3 to re-charge and terminating the alarm. R1 limits the current in the pendulum switch SW3 to a few microamps, so as to prevent welding of contacts.
