Title: Pvc footwear soling
Inventor: SISSON WILLIAM BERNARD
IPC: C08J7/043
Filed: 1968-07-09
Abstract: 1,219,155. Boots &c. VINATEX Ltd. 25 July, 1969 [9 July, 1968], No. 32673/68. Heading A3B. A sole or heel consists of a body of plasticized PVC and a coating, to protect the PVC from the effects of exposure to solvents, of a polymeric material having flex characteristics at least as good as those of the plasticized PVC. The polymeric material may be nitrile rubber, chloroprene, chlorosulphonated polyethylene or polyurethane and may be applied to the sole or heel as an emulsion or a solution by brushing, spraying or dipping. The coating may be applied only to the non-wearing surfaces of the sole or heel. In the case of one piece PVC boots, e.g. industrial boots, the sole, upper and leg areas may all be coated.

Title: Improvements relating to phase determining mechanism for telegraph apparatus
IPC: H04L17/16
Filed: 1936-11-30
Abstract: 484,318. Synchronous movements synchronism indicators. GRIFFITH, R. G., and WOOD, K. L. Nov. 30, 1936, No. 32689. [Class 40 (iii)] In a start-stop receiver or signal-regenerator the selector shaft is started at an instant whose relation to the timing of the received signals is automatically regulated so that the received impulses may take effect at or near their middle points ; or an alarm may be sounded when this relation fails to obtain. In a receiver of the kind described in Specification 439,745, a start shaft 79 is tripped by the incoming start impulse and acts through cam pins 89, 5, upon a detent 93 to release a second shaft 53 which drives the receiver selector shaft 55, which makes three revolutions for each signal group. The starting phase of shaft 55 is automatically adjusted so that the selecting instants determined by it may coincide as nearly as possible with the centres of the incoming impulses registered by the magnet armature 49. To this end the plate 21, which carries shaft 91 for adjusting the phase and a pointer 27 for indicating the adjustment, is turned about its pivot 22, as required, by the ratchet 19, which is moved in the earlier-starting direction by a pawl 24d, actuated by cam 26, at each revolution of the receiver shaft 53, and is moved in the later-starting direction whenever a catch 17 is tripped as a result of want of agreement in timing between the received signals and the selector shaft 55. The shaft 55 is moved axially to the left if, by a marking movement of the armature 49, the cam 52 is brought into the path of a pin 62 on the shaft, and it is moved rightward to the spacing position by engagement of the pin 62 with a fixed cam 63 ; the " selecting instant," at which cam 62 acts, coincides in perfect signalling with the middle of the received impulse. A marking movement of the armature also acts through linkwork upon springs 10 to move a lever 11 to the right. If the starting phase of the shaft 55 was sufficiently late, the lever 11 misses the blade 14 revolving with shaft 55 ; but otherwise the member 11 is stopped by the blade 14 and then caught by a cam pin 15 thereon and actuated so that, through the parts 13, 17, the ratchet 19 is released for one tooth and so adjusts the starting phase to be later than before. The blade 14 thus constitutes a " scrutinizing means." The movement of the phase-adjusting plate 21 is limited in one direction by co-operating stops 17a, 19a and in the other by a toothless portion of the ratchet 19. Instead of or in addition to the correcting action an alarm signal may be given when phase-adjustment is required. In another embodiment, Figs. 3, 4, 5 (not shown) phase-retarding adjustments are initiated by marking signals and phase-advancing adjustments by spacing signals.

Abstract: 951,152. Releasable-fastenings. TONKS (BIRMINGHAM) Ltd. Aug. 27, 1962 [Sept. 13, 1961], No. 32807/61. Heading E2A. Locking means for glass doors comprises a rail 3 adapted to be secured to the lower edge of a glass door 6 so that one end of the rail forms a continuation of the side edge of the door and a lock detachably secured within the rail and including locating means 10, 14 for the lock with respect to the rail but permitting longitudinal movement and angular movement of the lock relative to the rail and interengageable formations engagable upon longitudinal movement of the lock towards said end of the rail for preventing angular movement of the lock relative to the rail, the lower part 5 of said end of the rail being detachable and securable to the lock to prevent longitudinal movement and the arrangement being such that when said part 5 is removed the lock can be moved longitudinally as permitted by the locating means to disengage the interengageable formations, whereafter the lock can be moved angularly as permitted by the space between the bottom of the rail and the ground and can then be removed through said end of the rail without re-engaging the interengageable formations. In the construction shown the rail is of H shape in cross-section and at one end the upper groove and part of the lower groove is closed by a plate 4 welded in position, the remainder of the lower groove being closed by the end part 5 which is also a plate. The locating means for the lock comprises a block 10 in the lower groove, which has an aperture 11 for receiving a part 14 which extends from the lock case; the part 14 is a loose fit in the aperture 11 so that the angular movement referred to above is possible and so that the part 14 can be withdrawn from the aperture 11 by longitudinal movement of the lock. The interengageable formations comprise a plate 12 secured to the lock casing and a cross piece 8 which is secured in the lower groove against a ridge 7 which runs the length of the base of the groove and hence two passages are defined by the cross piece 8 on opposite sides of the ridge 7. The plate 12 has two projections 12a which can enter the passages 13. A screw which connects the plate 5 to the lock serves both to hold the plate in position and to hold the projections 12a in the passages 13.

Title: A comparison circuit for comparing a varying potential with a reference potential
IPC: H04B14/04
Filed: 1961-09-13
Abstract: 982,019. Transistor trigger circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 13, 1961 [Sept. 13, 1960], No. 32914/61. Heading H3T. A circuit for comparing a varying potential with a reference potential, e.g. an analoguedigital converter comprises a semi-conductor device Q 1  having its emitter electrode connected to the source of reference potential E R , and its base connected to the source of varying potential U and also via a rectifier device D 2 , to a source of control pulses; and a transformer Tr connected to provide positive feedback. The circuit is so arranged that in the absence of a control pulse, rectifying device D 2  conducts to reverse bias the base of the semiconductor device, and the presence of a control pulse cuts-off the rectifying device to allow the semi-conductor device to conduct when the varying potential exceeds the reference potential, so producing an output pulse. The length of the output pulse may be governed by the length of the control pulse or the time period of the regeneration process, depending on their relative values. In order to compensate for temperature variations in the base-emitter potential of Q 1 , the reference potential may be connected via a transistor Q 2  so arranged that the variations in base-emitter potentials of the two transistors cancel out.

Title: Improvements in or relating to indicators for displaying variable information
IPC: G09F11/26
Filed: 1934-11-16
Abstract: 437,914. Moving signs. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and WILMAN, C. W., c /o Ericsson Telephone Works, Beeston, Nottingham. Nov. 16, 1934, No. 32992. [Class 3 (i)] In display bands the movement of which is controlled by electric contact brushes cooperating with suitably disposed apertures in the band, the brushes bear on the band only at points between the successive representations thereon to avoid unnecessary defacement of the representations, wear of the band and brushes, and power waste. The Figure shows a toothed roller 20 over which the band passes, the band being preferably so wove over guide rolls that its display face is presented to the roller surface. Along the roller extends an electrically insulated rod 29 which at each revolution of the roller raises the band into contact with phosphor bronze or like wire brushes a, b, c, d, e, f. The rod 29 coincides with the parts of the band intermediate the representations, at which parts are provided, across the band, a series of holes positionally disposed in various permutations. The rod 29 thus contacts at each rotation with a different set of brushes a-f, thus enabling the band to be stopped at any preselected combination. Another brush 45 bears on a rim contact 27 mounted on the roller, and touches the rod 29 for a period slightly less than the contact periods of the brushes a-f, the purpose of the brush 45 being to ensure correct registration of the display in its window. All the brush ends rest in guide slots in a member 44, the slot receiving the brush 45 being deeper than the others to ensure proper contact between brush and rim 27. The roller 20 is carried on ball bearings and is fitted with a unidirectional clutch, of the spring or pawl-and-ratchet variety, to prevent back-lash. The nearest band-engaging teeth 5 are spaced from the rod 29 a distance such that no strain on the band is caused in the section raised by the rod 29. The band may be of bookbinder's cloth cut on the cross to prevent fraying, the ends being laced together by a strip of celluloid &c., and it is arranged on its guide rollers to be loose at the display window to enable it to assume a flat condition thereat. An armature 6 having cut-away teeth 42 is provided at each end of the roller 20 for actuation by electromagnets, as described in Specification 432,447, and a notch is provided in the armature 6 for engagement by a positioning pawl electromagnetically controlled by the brush 45.

Abstract: 480,978. Lubricating-pumps. ROWLAND, T. C. E., and PARKER, H. Dec. 7, 1936, No. 33543. [Class 102 (i)] In a lubricating-pump in which a single cylinder discharges lubricant to a number of points by means of a rotary distributer and the lubricant is trapped between the plunger and a piston discharge valve, the stroke of the latter is varied by means of stops. The invention is shown as applied to the pump described in Specification 459,946. The plunger 30, Fig. 1, reciprocating in a bore in a rotary body 2, discharges the lubricant to pipes carried by the end plate 10, and the stroke of the discharge valve 52 is varied by means of a stop 55, which passes through a slot 101 in a guide 54 secured to the body 2. The stop 55 is integral with a sleeve 53, carrying an arm 58 which comes in contact with studs 59. The latter may alternate with, or be replaced by, ribs on the cap 60, or on a plate attached to the cap. In a modification the stop 55 and sleeve 53 are replaced by a lever, pivoted to the body 2, and engaging the stops 59. The body 2 rotates in a liner 65, and the discharge passages 18 are provided with check valves 70. The inlet pipe 66 communicates with a groove 68 in the body 2. In addition to the pawl for rotating the wheel 43 attached to the body 2, a check pawl 104 is provided, pivoted to an abutment 102 by means of a stud 108, which also serves to prevent endwise movement of the body 2.
