Abstract: 1,262,724. Grinding stones. NIPPON TOKI K.K. 10 Dec., 1969 [17 June, 1969], No. 60400/69. Heading C4V. A method of making grinding stones comprises mixing a particulate abrasive material with a synthetic resin binder and/or a synthetic or natural rubber binder in liquid form to produce a slurry-like mixture, squeezing the mixture on to a support by the screen-printing technique to form a print of the mixture on the support and curing and aging the print to obtain a grinding stone. The resin may be a phenolformaldehyde resin of the resol or novolak type, which may be employed as solutions, and unsaturated polyester resins and rubbers, liquefied by heating. Curing agents of which numerous examples are given may be present. The abrasive materials may be diamond, fused alumina, sintered alumina, silicon carbide, boron carbide, emery and garnet. Fillers, of which many are specified, may be present as well as other additives such as accelerators, tackifiers and stiffeners. The support may be of paper, glass fibre cloth, non-woven glass fibre cloth, or non-woven synthetic resin cloth. The thickness of the print can be controlled by keeping the screen a suitable distance away from the support, repeating the squeezing operation, or bonding two or more prints to each other.

Title: Stranding machine
IPC: D07B7/06
Filed: 1980-12-10
Abstract: In a stranding machine comprising a plurality of aligned, hollow shafts each having a pair of bobbins rotatably mounted thereon (one such shaft 5 and one of its bobbins 8 being shown), one bobbin of each pair being used for stranding whilst the other is winding up fresh wire and then the roles of the two bobbins being exchanged, a braking means (not shown) is provided to regulate the tension in the wire 2 as it is drawn from the stranding bobbin and guided into the hollow shaft 5 through which it is drawn to the stranding station. Thus, the wire passes over a pulley 41 carried by a lever 36, the movement of which under the action of the wire tension (opposed by a spring) is used to regulate a braking force on the bobbin 8. As the machine stops and the consequent reduction in wire tension is sensed, maximum braking torque is applied to the bobbin 8. For use of that bobbin in the next phase (rewinding) the brake is readily disengaged altogether. <IMAGE>

Patent GB-2071334-A (GB)
Title: Contactless switch
IPC: H03K17/97
Filed: 1981-03-04
Abstract: A contactless switch is described which, on operation of a switch key (1), produces a non-transient switch signal which is maintained until it is cancelled by an interrogation operation. For this purpose, the switch (1) contains a bistable magnetic element (4), the direction of magnetisation of which is adjusted by operation of the switch key (1) into a predetermined direction. A permanent magnet (3), for example, is coupled to the switch key (1), which magnet (3) is moved towards the bistable magnetic element (4) when the key is operated. In order to ascertain the state of the switch, the bistable magnetic element (4) is coupled with an electrical winding (5), to which voltage pulses are fed which produce magnetic field pulses capable of reversing the polarity of the bistable magnetic element (4), if said element was suitably premagnetised by operation of the switch (1). The reversal of polarity occurs abruptly and the abrupt change of magnetic field associated therewith can induce, in the same winding (5) or in a separate winding, an electrical voltage pulse. <IMAGE>
