Abstract: 1290027 Strap &c tensioning tools STRAPEX AG 18 March 1970 [20 March 1969] 12947/70 Heading F2G  A tool for tensioning plastics strap around a case &c. comprises a strap clamp, a knife and a stretching mechanism, all actuated by a single lever and mounted on plastics shafts in a plastics support, the strap clamp comprising a first clamp face carried on one of the shafts and co-operating with a second, toothed, clamping face. As shown, a strap 5 is passed around a case &c. and into the tool, which comprises an operating lever 29 pivoted anti-clockwise from the rest position illustrated about its plastics shaft 22. A plastics shaft 6 is thereby released by withdrawal of a nose 48 on the lever 29, retaining a stop 16 on a disc 14 carried by the shaft 6, to permit a spring 18 to turn the shaft 6. A clamping face 7<SP>1</SP>, Fig. 1, on a clamping disc fast on the shaft 6, accordingly engages one end 5<SP>1</SP> of the strap and holds it against a toothed surface 8 of a second clamping member. The toothed clamping member 8 &c. can slide relatively to the tool frame 1 against the bias of a spring 10 as the strap end 5<SP>1</SP> is pulled, to increase the clamping effect of the clamps 7<SP>1</SP>, 8. Continued rotation of the operating lever 29 anti-clockwise acts through a spring-biased pawl-and-ratchet 32 &c., Fig. 2, to turn the plastics shaft 24 which has a transverse slit 27 at its end through which the other end 5<SP>11</SP> of the strap is passed. The strap 5 is thus tensioned about its case. The lever 29 may be oscillated back-and-forth till the desired tension is reached, a one-way spring biased detent 35 preventing reverse rotation of the tensioning shaft 22. The other end 5<SP>11</SP> of the strap is threaded through a slotted, fixed, plastics knife blade support 38 into which is moulded a fixed slotted blade 40, before affixing in the tensioning shaft slot 27. A shaft 42 is journalled through the blade support 38 and has a cutting knife edge 43. Discs 45 fast with the knife shaft 42 have a nose 46 which engages with lost motion a slot 47 in one end portion of the operating lever 29. When the desired strap tension has been achieved, a seal 49 is secured across the strap ends and the operating lever 29 is oscillated further anti-clockwise, so that the end of its slot 47 engages the nose 46 of the discs 45 fast on the knife shaft 42, thereby turned to sever the strap. The loose ends of the strap can then be withdrawn from the tool.

Abstract: 1295862 Fuel cell system ENERGY CONVERSION Ltd 27 Jan 1970 [28 Feb 1969] 10813/69 Heading H1B In a fuel cell system which comprises a cell or cells having hydrophobic catalysed porous nickel electrodes and which uses hydrogen as the fuel and oxygen or air as the oxidant, the air or oxygen flow rate is controlled to be proportional to current being taken from the system, a temperature and water balance being achieved in accordance with the electrolyte strength. In the embodiment the current flowing in the lead from cell stack 11 to terminal V<SP>+</SP> is sensed by circuit 13 which feeds a signal to a controller circuit 14 which controls the motor of compressor 15, the output conduit 16 of which feeds oxidant air to cell stack 11. Electrolyte e.g. KOH is pumped via reservoir 17 through cell stack 11 and fan blown heat exchanger 18 in series. The mean of the input and output electrolyte temperature to and from the cell stack 11 is sensed at circuit 24 and the signal produced controls the fan on heat exchanger 18. Water is removed to a first approximation by setting the air flow rate proportional to current. The final control of water balance is achieved by sensing the electrolyte volume and thus the electrolyte strength by means of level sensor probes 27-30 in electrolyte reservoir 17. The sensors are connected to level sensing circuit 32 the output of which is fed to temperature averaging circuit 24 which controls the fan on heat exchanger 18. If too much or too little water is removed the mean electrolyte temperature is reset to a lower or higher temperature, respectively, until the electrolyte strength reaches its nominal value.

Title: Disc brakes

Abstract: 1311676 Spot-type disc brakes GIRLING Ltd 13 Aug 1970 [19 Aug 1969] 41307/69 Heading F2E In a disc brake having a clamping member 13 mounted with clearance for sliding movement relative to a body member 10, one of the members has a wedge-piece 30 movable therein to maintain a sliding surface 32 on the wedge-piece in contact with a corresponding sliding surface 27 on the other of the members to take up play at the clearance. As shown, a fixed body member 10 with mounting ears 18, a through bore 20 and lugs 11, 12, is also provided with longitudinal grooves 16, 17, to accommodate a plate-like slidable yoke 13 which straddles the disc (not shown). The yoke is prevented from rattling in the grooves by springs 21. To avoid the need for close manufacturing tolerances and yet avoid the noise generated, on reversal of the direction of rotation, 29, of the disc, by movement of yoke 13 to the right in consequence of drag forces, a wedge-piece 30 is inserted in a bore 31 in lug 12. The wedge-piece has a wedge surface 32 co-operating with the surface 27 of the inside edge 15 of yoke 13, thereby maintaining the clearance gap 28, Fig. 2, at the left hand side of the body member, and keeping the yoke surface 26 and groove surface 24 in contact at the right-hand side, in whichever direction the disc rotates. The wedge-piece 30 is resiliently urged downwards by a spring 33 retained by grub screw 34.  As shown, the angle of inclination of wedge surface 32 and of the axis of bore 31 (preferably the same) are so chosen that contact pressure at surfaces 27, 32, does not lead to movement of the wedge-piece. Spring 33 is made weak enough to avoid inhibiting normal sliding movement of the yoke. The angles above referred to could alternatively be so chosen that contact pressure due to drag forces would move the wedge-piece to "cushion" the relative movement at the sliding surfaces. Preferably the body member accommodates an hydraulic actuator in the form of two opposed pistons slidable in the through bore 20, one of these acting directly on a brake pad located between the lugs 11, 12, and the other acting on one end of the yoke, whose opposite end bears against a pad located at the opposite side of the disc (e.g. as described in Specification 1,075,371). Alternatively, the body member may be pivoted about an axis close to but perpendicular to the disc axis, and may incorporate a blind bore slidably receiving a piston acting on the yoke; the body member itself acts on the directlyoperated pad.
