Patent GB-2175466-A (GB)
Title: D.C. motor protection
Inventor: JONES DENNIS MALCOLM
IPC: H02H7/08
Filed: 1985-05-10
Abstract: A controller for an electric vehicle is arranged to sense an over-current fault in the electric drive motor 6 and cause at least one contactor to open and thus break the current to the motor armature, and is further arranged to modify the motor field current so as to cause a reduction in the armature current during a time period which it takes for the contactor to open. If the armature current at fault is in the usual motoring direction a contactor C (or D) is opened and next the current through shunt field winding 8 is increased (by control of a pulsed transistor 10) in order to reduce the armature current, then contactor A is opened. In regenerative braking mode, the armature current is in the opposite direction and the over- current fault will cause contactor B to be opened and then the current through winding 8 reduced in order to reduce the armature current. <IMAGE>

Title: Conduit connector structure and sealing ring
Inventor: POE JACK L
IPC: F16L23/20
Filed: 1985-05-21
Abstract: A conduit-connector coupling structure has clamp segments (11,12) operating to cam together two flange members (27,28). The forward flange portions (25,26) of each of the flange members (27,28) together define conical recesses accommodating a metallic sealing ring (35). When the flange members are drawn together the sealing ring (35) is held in radial compression. The ring itself is provided with mutually spaced peripheral sealing lands (36,37) on respective ones of its oppositely tapered sides. The ring (35) is designed so that the recesses (40) separating the lands (36,37) will maintain their integrity for all radial compressions of the ring within the elastic limit and below the yield point of the material of the ring (35). The provision of a plurality of lands (36,37) ensures an effective sealing action even when one of the lands (36,37) is marred or damaged. <IMAGE>

Patent GB-2187984-A (GB)
Title: Casting molten metal
Inventor: SMITH ROBERT ARTHUR
IPC: B22D27/08
Filed: 1987-02-23
Abstract: A method of making a casting comprising the steps of, at a casting station (CA), feeding molten metal from a primary source (16) of molten metal into a mould cavity (15) through an ingate (49) below the top of the mould cavity, placing the cavity out of feeding relationship with the primary source by partially or wholly inverting the mould to prevent flow of molten metal from the cavity towards the primary source and to permit of flow of metal from a secondary source, constituted by a header (42) filled with metal, to the cavity, the cavity being continuously connected to the primary source during said inversion, transferring the mould cavity to a cooling station spaced from the casting station and, at the cooling station, permitting molten metal to flow to the cavity from the secondary source whilst the metal in the cavity solidifies. The mould and its support are connected through a separable rotary joint (37) to the primary source so that both inversion and removal to the cooling station may be performed by a manipulator (50). Mould filling, by low pressure, may be performed by electromagnetic pumping, or air pressure or vacuum. The mould may be permanent or one-use (e.g. with cavity defined by a polystyrene pattern). <IMAGE>
Patent GB-2206165-A (GB)
Title: Slack adjuster
Inventor: WASHBOURN JACK
IPC: B61H15/00
Filed: 1987-06-16
Abstract: A slack adjuster comprises a housing 1 in which is located two nuts 18, 30 each in non self-locking threaded engagement with a common spindle 25, one of the nuts 18 being an output nut by which an output force can be transmitted to the spindle and the other of the nuts 30 being an adjuster nut by axial movement of which on the spindle relative to the output nut adjustment of slack is effected. The adjuster nut is in splined connection with an annular member 33 encircling the spindle and resilient means 39 urges the annular member into engagement with the housing. Abutment means 36 is carried by the adjuster nut and, upon axial movement of the adjuster nut a distance x corresponding to the required degree of slack, the annular member is "picked up" by the abutment means and thereafter during continued movement of the spindle to take up any excessive slack the adjuster nut is freed to spin on the spindle as it is drawn through the adjuster nut, thus causing an axial separation of the nuts. Upon brake release, return spring 5 forces piston 4 to the right and results in, firstly, nut 30 in its adjusted position in spindle 25 being brought into abutment with the housing, and, secondly, nut 18 being spun along the now stationary spindle until the nuts are again positioned relatively as illustrated. <IMAGE>

Title: Improvements in or relating to fastening devices
Inventor: CHAMBERLAIN CHRISTOPHER RAYMON
IPC: B42D1/06
Filed: 1987-11-30
Abstract: A fastening device is provided for attachment to a sheet-like material, and is particularly suitable for fastening a cheque book 10 within a cover 16. A book retainer 17 is fitted to the cover 16 by passing the head 28 of a stud 26 into a key-hole slot 20. In the embodiment shown the portion of the cover 16 between two key-hole slots 20, 21 is then flexed to enable the head of the mother stud 26 to be passed through the other hole at its larger end. The resilience of the cover then flattens out the flexed portion between the holes to retain both studs against release movement. In another embodiment a single stud is employed with an associated flexible catch which snaps into the larger end of the key-hole slot to resist release movement of the stud from the narrow end. <IMAGE>
