Abstract: 1416450 Film cartridges EASTMAN KODAK CO 9 Nov 1972 [15 Nov 1971] 51787/72 Heading B8M [Also in Divisions G2-G3] A film strip 17 for use in a cartridge (Fig. 1) which includes a perforation 29 whose direction of elongation is inclined to the film axis so as to be engaged by a tooth 25. The tooth 25 has undercut faces 35, 37 as shown in Fig. 3, which engage the perforation 29 and apply a transverse force to the film as it tries to advance in the direction of the arrow. Further application of force to cause film advance causes the film end to curl up into contact with the faces 35, 37. The film may have a backing paper having a cut-out in the region of the perforation 29. Such an arrangement is used to prevent the end of the film 17 entering the take-up spool 23.

Abstract: 1327436 Rotary/percussive drills ROBERT BOSCH GmbH 12 Nov 1970 [15 Nov 1969] 53808/70 Heading B3C [Also in Division B4] A drill which can effect a pure rotary drilling operation or a rotary percussive drilling operation comprises a selector pin 35 which in the illustrated position permits a work spindle 11, carrying a gear wheel 10 secured thereto, to be moved rearwardly against bias of spring 27 so as to effect engagement of teeth 24 on the gear wheel 10 and teeth 25 on a member 26 secured in the housing 4. Rotation of the pin 35 to bring face 41 into contact with a sleeve 31 causes the latter and a thrust bearing 28 to be moved forwardly such that rearward movement of the spindle sufficient to bring the teeth 24, 25 into engagement is prevented by engagement of a shoulder 211 with the thrust bearing 28. Additional flat faces may be provided on the pin so as to allow the teeth 24, 25 to partly engage to varying degrees.

Abstract: 1,115,267. Fluid-pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 6 Dec., 1966 [21 Dec., 1965], No. 54067/65. Heading F2F. In a fluid-pressure braking system, e.g. a compressed-air system for road vehicles, having both service and emergency spring actuators 22, 11, respectively, the former being supplied by a reservoir 6 via a conduit 18 under control of a driver's valve 15, and the latter having a chamber 10 for compressing the spring 13 which is supplied by a reservoir 5 under control of a manually operated valve 7, the exhaust of the valve 7, which releases fluid from the chamber 10 to apply the spring brake, is connected via a non-return valve 8 to the conduit 18, so that the released fluid can exhaust only via the exhaust 16 of the driver's valve, the valve 8 being resiliently loaded in the forward direction to further retard release from the chamber 10. This ensures that, whatever pressure exists in the chamber 19 of the service actuator 22 at the time the valve 7 is operated to effect an emergency spring application of the brake, the total brake-applying force will not exceed the maximum force due to a service application alone.

Title: Improvements in or relating to shoe upper conforming machines
IPC: A43D23/00
Filed: 1969-10-27
Abstract: 1,235,096. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. 27 Oct., 1969 [31 Jan., 1969; 6 June, 1969], No. 52453/69. Heading A3B. A lasting machine includes a shoe rest 10, an insole plate 11 (which may apply adhesive along channel 16) which surrounds the shoe rest 10, wipers 7 and means for temporarily arresting the advance of the wipers 7 at a position (shown dotted) where the leading edges of the wipers 7 engage the lasting margin 25 and press the lasting margin 25 against the outer edge of the insole 8, the insole plate 11 being withdrawn while the wipers are temporarily arrested. A time delay device ensures that the insole plate 11 is not withdrawn until the wipers are temporarily arrested. In a first embodiment the time delay device is mechanical and consists of a moving control finger 13 which initially operates valve 14 to move piston 4 to the right (Fig. 1) and thus advance the wipers 7. The wipers 7 are temporarily arrested when a stop 1 on the piston rod 18 contacts an abutment surface on a wedge member 2. After a predetermined time delay the control finger 13 actuates valve 15 to cause piston 21 and cylinder 22 to lower the insole plate 11. During this movement a cam 34 on the piston rod 20 operates switch 26 which causes piston and cylinder 3 to raise the wedge member 2 and thus allow the wipers 7 to complete their wiping operation. In a second embodiment (not shown) the time-delay is provided by an electrical device, and in a third embodiment (not shown) the time delay is provided by the build-up in pressure to the left of piston 4, a counter-pressure being established to the right of piston 4 to ensure that the wedge 2 can be retracted without undue friction between the wedge 2 and stop 1.

The transfer index is defined by the relationship where (P 2 O 5 ), (CaO), (SO 3 ) and (F-fluorine) are the respective weight percentages in the reaction product and (M) is the sum of the weight percentages of Al 2 O 3 , SiO 2 , Fe 2 O 3 , MgO and alkali metal oxides, the quantity E being, for all practical purposes, the percentage of water in the composition. The organic solvent may be an aliphatic alcohol. where n is an integer of 1-3, m is 0 or 1, R<SP>1</SP> is an aliphatic hydrocarbon residue having 2 to 8 carbon atoms, whose carbon chain is optionally interrupted by an ether-type oxygen atom and R<SP>2</SP> is a H atom or an alkyl group of up to 4 carbon atoms. The preferred organic solvent is butanol and the organic solvent may contain water in an amount of at most x parts by weight where x = y-z, z is the weight of water present in the phosphate rock and y is that weight of water which if present in the rock would give a transfer index of 0À8. Other organic solvents mentioned include organic sulphoxides, organic phosphates, organic amines and quaternary organic ammonium salts.

The covers each have rollers such as 3a, 3a<SP>1</SP> running along the rails 2 with openings such as 4a, 4a<SP>1</SP> into which the rollers are received when the covers are lowered. In this position the covers are also sealed to the coaming by co-operating sealing gaskets and bars (60, 61, Fig. 6a, not shown), and are locked by hooks 5a, 5b. Co-operating pins and sockets 10, 9a ensure correct alignment of the covers in their closed positions. For raising the covers, pivoted levers such as 50a, 51a with lower cam surfaces are raised to the level of the rail surface by rollers 56 on a rod 13 movable longitudinally by an hydraulic jack 15. In their raised positions the covers are tilted, Fig. 1b (not shown), to ensure disengagement of the transverse sealing gaskets and bars 7a, 8a. The covers are connected together by chains or links and are moved to the right into a vertically stacked position by a cable 25, Fig. 8, actuated by the rod 13 and connected to the end cover ln. Another cable 29 is used to close the covers. Manipulation of individual covers is effected by a rocking lever (18, Fig. 7, not shown) actuated by hydraulic jacks (19, 19<SP>1</SP>) and which engages side lugs (20b) on the covers.
