Title: Force actuator
IPC: B60T17/08
Filed: 1981-07-17
Abstract: A force actuator, for example for a vehicle braking system comprises a primary member 5 movable for initiating force actuation and a secondary member 20 movable to apply a force. The members 5, 20 are coupled by displacement magnifying means 15-18 through a force- responsive link 19, 30, 31 to move the secondary member 20 in response to, and at a speed in excess of, movement of the primary member 5. The force- responsive link 19, 30, 31 is arranged to override the coupling when the applied force exceeds a predetermined value to effect direct connection through clutch faces 23, 24 of the secondary member 20 to the primary member 5. In application to a braking system the coupled movement of the secondary member can quickly take up slack in the brake linkage or rigging whereupon full braking force can be transmitted by the direct connection of the members. Preferred displacement magnifying means comprises first-order levers 15 and a preferred force responsive link includes a spring 31 which when unable to transmit the applied force yields so that primary member 5 moves into engagement with the member 20 of faces 23, 24. The primary member 5 may be moved by fluid pressure. Mechanical means may be included for retracting the members to release an applied force. <IMAGE>

Patent GB-2104002-A (GB)
Title: Multi-purpose bookbinding press
Inventor: BECK DEREK JAMES CALVERT
IPC: B42C13/00
Filed: 1981-12-11
Abstract: This invention relates to a piece of bookbinding equipment, light and portable enough to be used in a small flat that can perform the functions of the three types of press used in hand bookbinding-laying presses, finishing presses and nipping presses. The first two hold the book vertically and for most of the work done in them the pressure is required to be concentrated along the edge of the book whereas a nipping press which holds the book horizontally is required to produce a substantially uniform pressure on its faces. The press in the invention combines the central screw of a nipping press with clamping screws which are inserted close to the long edges of the platens when the press is used for operations normally done in a laying press. It also allows the central screw to be moved to either edge of the platens so as to reduce their deflection. The press can be turned on edge to hold the book vertically and one pair of long edges is provided with guides for a bookbinders plough whilst the others slope back like the cheeks of a finishing press to provide clearance for the binder's hands. <IMAGE>
Patent GB-2100884-A (GB)
Title: Disk storage system
Inventor: KASETA ROBERT G
IPC: H02P8/14
Filed: 1979-02-28
Abstract: The read/write head of a disc storage system is positioned by a stepping motor having four coils 11A, 11B, 11C, 11D. The coils are energised under the control of a pulse logic circuit 20 with combinations of pulses such as to effect rotation step by step in the desired sense. Excitation circuits 10A, 10B, 10C, 10D provide constant pulse currents. In order to avoid oscillation at the end of a movement, the pattern of energisation is modified during the last stepping interval. During this interval the coils are initially energised with the pulse combination corresponding to that interval, then with the pulse combination applying to the preceding interval and finally with the pulse combination applying to the last interval itself again. This damps the movement of the stepping motor and read/write head. <IMAGE>

Title: Improvement in and relating to an enzyme for decomposition of a high molecular carbohydrate, the isolated high molecular carbohydrate, a method for selection of a microorganism producing such enzyme and a method for production of such enzyme
Inventor: GUERTLER HENRIK
IPC: A23C11/10
Filed: 1982-12-21
Abstract: The enzyme, which is able to decompose a high molecular carbohydrate, abbreviated SPS (soluble polysaccaride), is designated SPS-ase. The SPS-ase is able to decompose SPS into decomposition products which attach themselves to protein in an aqueous medium to a lesser extent than the SPS prior to decomposition. The method for selection of SPS-ase producing microorganisms is based on the fact that the main carbon source of a growth medium is SPS and on a qualitative SPS-agar plate test. A method for production of an SPS-ase by means of a deposited strain of Asp. aculeatus is described. The SPS-ase also has utility in the fruit and vegetable industry and for production of juice and wine.
