Abstract: 1,136,995. Packages; collapsible containers; bags. C. FIQUET, and R. LEPLAT. 8 Nov., 1966 [9 Nov., 1965; 28 Sept., 1966], No. 50034/66. Headings B8C, B8D, B8K and B8T. Pasty or liquid products are dispensed from a bag 2 of elastomeric material, e.g. plastified p.v.c., polyethylene, or super-polyamide, one end of the bag being attached to an outlet 7 of a casing 1 and the other to a rotatable end piece 5 of the casing so that the bag may be twisted. The shape of the bag ensures that twisting begins at the end opposite the outlet, and the bag material allows for shortening of the bag as it is twisted. To form the bags a tube 11 is provided at intervals with pairs of nozzles 12, Fig. 6, attached to the tube, e.g. by high frequency welding or by the use of an adhesive, symmetrically on either side of the longitudinal axis of the tube. The tube is then filled and welded between the pairs of necks as at 13. Single bags may then be cut from the tube, and each bag mounted in a casing 1 by screwing the nozzles into the end members of the casing. In a modification each bag is of generally rectangular shape, Fig. 8 (not shown), a zone (15) of reduced resistance to twisting being formed at one end; or the respective nozzles 12 may be attached to the bag by flanges which differ in size, shape or rigidity; or one set of the nozzles 12 may be attached to thinner parts of the bags. The bags may have nozzles of square crosssection, Fig. 9 (not shown), fixed to the casing ends by forked members (19) engaging grooves in the nozzles. A pad (23), Figs. 10-11 (not shown), of porous material and having a central hole (24) may be carried by an end piece of the casing and be closed by a cap (24) having a member (25) for piercing the bag neck. The casing may be in the form of a pistol, Fig. 12 (not shown), having a trigger which causes an end member (29) to rotate and thereby twist the bag. The casing may be equipped with a shaving brush, or tooth brush.
Patent GB-1209304-A (GB)
Title: Improvements in or relating to electrical pulse monitoring circuits
Inventor: CAPPER BRIAN HARFORD
IPC: G06F11/16
Filed: 1966-11-10
Abstract: 1,209,304. Magnetic drum stores. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 8 Nov., 1967 [10 Nov., 1966], No. 50531/66. Heading G4C. [Also in Divisions G1, H2 and H3] In an arrangement for providing an indication of the failure of one of n sources of identical pulse trains S1-S3, pulses from these sources are applied as strobe pulses to a plurality of pairs of associated bi-stable circuits TA-TF and failure of one of the sources S1-S3 is indicated by operation of detection devices such as relays 1ALR-3ALR associated with each pair of bi-stable circuits to which the failed source is applied. The outputs of the bi-stable circuits TA, TB of each pair are set to opposite states by momentarily operating reset key KR to apply earth potential via isolating diodes DADF to the outputs of the bi-stable circuits. This causes the bi-stable circuits TA, TB to be in the " 1 " and " 0 " state so that a " 0 " output is applied from both bi-stable circuits TA, TB to the associated relay 1ALR which is not energized. When the strobe inputs S1 and S2 occur at the strobe inputs X, Y (Fig. 1) of each bi-stable circuit TA, TB the state of each bistable circuit changes so that a " 1 " output is applied to each terminal of the relay 1ALR. If one of these strobe pulses fails then the state of one of the bi-stable circuits remains unchanged and the outputs applied to the relay 1ALR become 1, 0 or 0, 1 and the relay 1ALR is energized to close its contact 1ALR1 and operate a strobe fail alarm SFA. Failure of both S1 and S2 will not operate relay 1ARL but will operate relay 2ALR. Similar operation occurs for failure of S3 and combinations of S1, S2 and S3 except that failure of all three will not be detected. The circuit operates to fail safe since if one of the bi-stable circuits fails the next strobe pulse applied to it will result in the failure alarm being given. The alarm relays may be replaced by a gate arranged to detect the same output state of the bi-stables. Each bi-stable circuits (Fig. 1) have input gates DA, DB, DS which only allow signals at the control inputs I/PS and I/PR to change the state of the bistable circuit provided a strobe pulse is applied to both X and Y strobe inputs. The arrangement may detect the failure of a strobe source or the omission of a single strobe pulse, e.g. due to a flaw in an oxide coating where the strobe sources are derived from three sync. tracks on a magnetic drum by means of a sync. track reading head. Three strobe or clock pulse sources may be combined in a two-out of three majority gate, the output of which is used to drive a strobe distribution amplifier supplying a strobe controlled system.
Patent GB-508102-A (GB)
Abstract: 508,102. Starting prime movers. ECLIPSE MACHINE CO. Jan. 27, 1937, No. 2391. Convention date, Jan. 28, 1936. [Class 38 (iv)] [Also in Group XXXVII] An electric starting system for internal combustion engines comprises a starting switch wherein a manually operable member, such as an accelerator pedal, for controlling the engine or its associated plant, moves the switch towards the closed position but is inoperative to effect closure thereof, the closure being completed and maintained by means which are inoperative when the engine is running under its own power. The starting motor 7 is energized on closure of contacts 15, 16 by a bridge 18 fixed to a spindle 19 which passes through the core of an electro-magnet 22 and has a magnetic disc 24 secured to it. The electro-magnet 22 is energized when the ignition switch is closed but its attraction on the disc 24 is insufficient to close the switch. Depression of the accelerator pedal causes movement of a slide 38 in a guide block 32 and causes vertical movement of a roller 37 mounted in a slot in the guide 32 so as to ride on an inclined face 42 of the slide 38. Roller 37 operates through a bell-crank lever 36, 34 on the spindle 19 of the starter switch so as to bring the disc 24 into the sphere of control of the electro-magnet 22 which then completes the closure of the switch. The electro-magnet 22 is energized from the battery in series with a switch sensitive to backfire, a switch sensitive to the vacuum in the intake and an engine-driven generator in opposition to the battery. Backfire or self-operation of the engine causes de-energization of the electromagnet 22 and opening of the starter switch. The switch operated in response to engine suction may cause the insertion or shortcircuiting of a resistance in the electro-magnet circuit, so that if, during cranking, the switch opens, the electro-magnet excitation is reduced, but the starter switch is not opened until the generator voltage is sufficient to de-energize the solenoid 22.

Abstract: 1,240,076. Valves. GENERAL MOTORS CORP. 28 Oct., 1969 [28 Oct., 1968], No. 52706/69. Heading F2V. [Also in Division F1] In a gas turbine engine the flow of cooling air from the engine compressor to hollow turbine blades mounted on a rotor disc 16 is controlled by an annular bi-metallic valve member 72 mounted on a ring 71 adjacent the disc 16. In the closed position valve member 72 bears on a sealing plate 47 secured to the disc to prevent cooling air flowing from space 57 through holes 60 and to holes 62 leading to the blade interiors. Some air, however, always flows over valve member 72 from holes 73 in ring 71 and an increase in temperature of this air causes member 72 to distort to the right to increase the flow through holes 60. The member 72 is so shaped that the increased centrifugal force at higher rotational speeds also causes distortion and an increase in the flow. A slightly modified bimetallic valve member (75) is illustrated in Fig. 3 (not shown).

Abstract: 1279289 Diaphragm springs FOXBORO CO 28 Oct 1969 [1 Nov 1968] 52723/69 Heading F2S [Also in Divisions G1 G3 and H1] A diaphragm spring consists of a sheet (10) of metal cut out to form a cantilevered tongue 12. The sheet is backed by a rubber diaphragm 16 sealing the gap around the periphery of the tongue 12. A rigid stiffener 29 ensures flexing of the tongue only in the region of the axis 24. Movement of the tongue 12 in response to fluid pressure applied to the underside of the rubber diaphragm can be used to control or actuate an operating device such as a switch (hence the tap 29a). Alternatively the movement of the tongue can be arranged to indicate differential pressures across it to a sensing device which controls a feedback device to re-balance the pressures on either side. The diaphragm spring of Fig. 4 backed by a rubber diaphragm (50, Fig. 8, not shown) has tongues 32, 34, 36, 38 and 40 which are individually responsive to fluid pressure in an alarm system (Fig. 12, not shown) for notifying when a measured condition (e.g. temperature or flow-rate) in an industrial process goes above or below a certain level (see Divisions G1 and G3). Rectangular holes 220 reduce the spring rate of tongues 36 and 40. Tongues 34-40 are restrained by a coil spring (102) or a C-shaped spring (84, Fig. 12).
