Abstract: 1,225,739. Centrifugal pumps; hydraulic turbines. LENINGRADSKY METALLICHESKY ZAVOD IMENI XXII SIEZDA KPSS. June 24, 1969 [July 8, 1968], No.31764/69. Headings F1C and F1T. A hydraulic pump-turbine comprises an inner runner 1 having blades 2 and a concentric outer member 7 having adjustable blades 8, the member 7 being held stationary during turbine operation to form a nozzle array but being rotatable during pump operation at a speed exceeding that of the runner 1 in order to reduce cavitation. The runner 1 is attached to a shaft 5 coupled to a motorgenerator, the shaft 5 being supported in a bearing 18 within member 7. The latter is itself carried by a shaft 6 supported in a bearing 19 within a fixed member 17. A servomotor 23 carries a toothed stop 24 which can lock splines 20 on shaft 6 to splines 21 on a fixed member 22 during turbine operation but can be disengaged during pump operation to enable shaft 6 and member 7 to be driven. The drive to shaft 6 may be at a rotational speed up to 20% greater than that of shaft 5 and runner 1 and may be effected by a separate motor or by a torque converter or gearing from the motorgenerators. Angular adjustment of the blades 8 is effected by servomotors 12 driving a ring gear 11 meshing with a gear 10 on each blade 8. Sealing at the free ends of the blades 8 is effected during turbine operation by a seal ring 27 controlled by servomotors 28, the ring being retracted during pump operation to reduce friction.

Abstract: 1,231,197. Lamp failure alarms. JOSEPH LUCAS (INDUSTRIES) Ltd. 20 Aug., 1968 [11 Sept., 1967], No. 41298/67. Heading G4N. A lamp failure alarm utilizing the photoconductive properties of a reverse biased diode is shown in Fig. 2. Each diode is associated with a lamp such that with all the lamps on, the reverse current through the diodes keeps transistor 11 in saturation and transistor 16 biased off. If one of the monitored lamps should fail then the respective diode would pass a reduced current, switching off 11, switching on 16 and hence illuminating alarm light 15. 16 could be replaced by a thyristor, while of the circuit was used with a flashing light system the alarm light would under normal conditions flash out of phase with the flasher. In Fig. 1 (not shown) a plurality of diodes in the base/collector circuit of a transistor monitor their respective lamps such that failure of one of the lamps switches the alarm light off.

A manually operated apparatus for administering air or oxygenated air to a patient comprises a bag 10 having a non-rebreathing valve (described fully in Specification 1,238,649) and a non-return oxygen inlet valve through which oxygen from a cylinder may be supplied. When the bag is squeezed the increased pressure closes the non-return ball or needle valve, carrier 26 moves forward closing the inlet and outlet ports 27 and 25 and valve member 22 is displaced so opening the apertures 24. Air or oxygenated air may pass through the valve into the patient's lungs by way of a face mask (not shown). When the pressure on the bag is relaxed, the patient's breath replaces member 22, slides back carrier 26 and passes out through the ports 25. As the bag inflates air may be drawn in through ports 27 and oxygen or air through the now open non-return valve.

Abstract: 1289756 Watches BULOVA WATCH CO Inc 19 Feb 1970 [11 March 1969] 8127/70 Heading G3T A watch for indicating time in different geographic zones has an additional crown 4 which is used both for incremental setting of the zone time shown by an additional hour hand (36) Fig.3 (not shown) and for setting either a date ring 24 or alternatively an alarm. The crown 4 is attached to a stem 5 having a sliding pinion 8 which engages a wheel 16. The wheel 16 is carried on an axle 15 which also forms a pivot of a plate 12. The wheel 16 drives a second wheel (17) and thus wheels 19 and 29 carried on the plate 12. In the inner position of the stem 5, the free end of a spring 20 on the wheel 19 engages teeth 25 on the date ring 24 to advance the latter when the crown 4 is rotated in one direction only. In the reverse direction of rotation, the spring 20 jumps over the teeth 25. An alternative embodiment is described in which the date ring 24 is advanced by a pin on a disc which is driven through a Breguet toothing. In the outer position of the stem 5 a pinion 31, carried loosely on the wheel 29, engages a wheel 33 on an arbor (34) which carries the local time hour hand (36) and also a star wheel 35. Rotation of the crown 4 drives the wheel 31 via a sector (30) and a rib (32) on the wheels 29 and 31 respectively. The wheel 33 is moved to alter the setting of its hand (36) in one hour increments as a spring 38 on a further hour wheel 37 engages the star wheel 35. The gear ratios are so chosen that a conventional hour hand (46) rotates at half the speed of the extra hand (36) i.e. once in twenty four hours.

Abstract: 1295740 Slitting apparatus JOHN DUSENBERY CO Inc 14 July 1970 [28 April 1970] 34157/70 Heading B4B Foil slitting apparatus comprises a circular cutting knife 17, a circular backing disc 18, means mounting the knife 17 and disc 18 for rotation about a first axis normal to the plane of the disc 18, and means mounting the knife and disc for pivotal movement about a second axis normal to the first axis. The disc 18 has a frusto-conical surface portion against which the knife 17 is pressed so that its edge is offset from its general plane. As described, the knife 17, Fig. 5, is pressed against the edge portion of the disc 18 by a washer 21 and co-operates with a driven back-up knife 25. A resilient ring 27 in a groove in the disc 18 serves to minimize the tendency of the foil to wrinkle and causes the peripheral speed of the knife 17 to equal the linear speed of the foil. The knife and disc are carried by a shaft 20, Fig. 1, freely rotatable in a housing 28 fixed to a second housing 37 and lever 38. The housing 37 is mounted on a post upstanding from a slide plate 43 so as to be pivotable about an axis a. The assembly comprising the housings 28 and 37, and lever 38 is pivoted anti-clockwise by the piston 68 of a pneumatic cylinder 66 to urge the knife 17 axially against the knife 25, and the pivotal movement is limited by an adjustable stop screw 40. The slide plate 43 is mounted for sliding movement on a mounting bar. Rotation of a differential screw 56 threaded into a bracket 16 on the mounting bar causes the plate 43 to slide and thus enables the overlap between knives 17 and 25 to be adjusted.

Each sector contains a number of tubular ferrules at both the upper and lower faces of the grid, each corresponding pair of ferrules being penetrated by a fuel pin. As  shown in Fig. 3, two rigid support members 8 and a rigid back stop member 9 are formed in each of the upper ferrules 5, and one rigid support member 8 and two rigid back stop members 9 in each of the lower ferrules 6. Double bow springs 10 are fitted over the radial webs between the ferrules 5, 6, and serve  to hold the fuel pins in engagement with the  rigid support members 8. Should a bow spring  10 fail, the back stop members 9 serve to limit  lateral movement of the corresponding fuel  pin away from the rigid support members 8.  In an alternative embodiment (Fig. 6, not shown), the spacer grid comprises upper and lower grid structures both of square lattice form, made from thin strip material and joined by an outer support band. Double bow springs extend between the upper and lower grid structures and the strips forming these structures are shaped to provide rigid support and back stop members which serve the same purpose as the corresponding members in the previous embodiment.
