Title: Improvements in or relating to Pen Lifting Apparatus for Recorders
Inventor: LEIDY LESTER R
IPC: G01D15/18
Filed: 1968-08-19
Abstract: 1,172,947. Recording-apparatus. HONEYWELL Inc. Aug.19, 1968 [Aug. 25, 1967], No. 39543/68. Heading G1J. Two pen lifters 10, 14 are provided in apparatus having a pen 20, movable across recording medium 22, of which the first is manually operable and the second comprises a latch 84 adapted to retain a holder 24 for the medium 22 in operating position in relation to the pen but which can be operated to release the holder 24 and which is coupled to the pen so that when operated the pen is lifted from its recording position. The pen 20, fed from a reservoir through a capillary tube helically wound round a shaft 50, is mounted by a leaf-spring 82b on a carriage 18. The carriage 18 is slidable on a fixed shaft 83 and on the shaft 50 which is fixed to a stop plate 60 and eccentrically pivoted by pins 68, 78. A spring 54 urges the plate 60 in a clockwise direction and a crank arm 48 anti-clockwise. The manual lifter 10 comprises a push rod 26 which, when pushed inwards against the bias of the spring 54, rocks the crank 48 clockwise and the spring 54 applies a clockwise rotation to the plate 60 moving the shaft 50 upwards and tilting the carriage 18 to lift the pen 20 off the medium 22, after taking up lost motion between the carrier 18 and a screw 83a adjusted on the arm 82a carrying the pen. The latch 84 of the seond lifter 14 is urged by a spring 94 to retain a pin 110 on the holder 24 at the base of a slot 108 in the latch 84 and to release the holder 24 the latch 84 is pressed downwards at 114. When released, the holder 24 can be rocked outwards about its pivot 138 with the pin 110 riding on the surface 116 of the latch 84 until clear thereof. Meanwhile the other end of the latch 84 moves upwards allowing the spring 94 to push upwards a pin 104 on a second push rod 106. A slot 122 in the rod 106 engages a projection 124 on the plate 60 to lift the pen (unless it has already been lifted manually) and, as the pin 110 rides on the surface 116, the pen is gradually returned to its original position. When the holder 24 is rocked back again the pin 110 rides on the surface 116 of the latch 84 causing the pen to be lifted and when the pin 110 enters the slot 108, the latch pivots back and returns the pen 20 to recording position. An additional slot 158 in the rod 106 may co-operate with another stop plate for lifting a second pen, which can also have a manual lifter identical with the first lifter 10.

Title: Method for treading tyres
IPC: B29D30/44
Filed: 1973-09-07
Abstract: 1460297 Treading or retreading tyres KENTREDDER Ltd 9 Sept 1974 [7 Sept 1973 22 Nov 1973] 42208/73 and 54243/73 Heading B5A [Also in Division B7] A method of applying a tread band or lug to a tyre carcass comprises in either order the two steps of placing a pre-vulcanised tread band or lug on the carcass and shortening at least the ground engaging surface of the band or lug in a direction parallel to the longitudinal axis of the band or lug by exerting a compressive stress in that surface in that direction, the compressive stress being maintained while the band or lug is bonded to the carcass, wherein the steps are such that in the final assembly the ground engaging surface of the band or lug is compressed along its length with respect to its initial non- compressed state and has maintained therein a compressive stress. In one method a lug or an arcuate portion of a tread band having a radius of curvature r<SP>1</SP> is applied to a carcass portion 10 having a larger radius of curvature r. Four such arcuate portions may extend over the whole circumference of the carcass, and each portion or lug preferably includes an inextensible reinforcement along or adjacent its carcass engaging surface. In a further method, a preformed annular tread band and a carcass having an external diameter smaller than the internal diameter of the band are each coated with a bonding agent (e.g. unvulcanized rubber) and the band is applied to the carcass, with a layer of cushion rubber therebetween, by means of pressure applied to the band by an inflatable bag or a clamp. Alternatively the band may be applied to an inextensible breaker of smaller external diameter than the internal diameter of the band prior to application to the carcass. In another method, the annular tread band is formed in one mould and transferred to a smaller mould 21 and the carcass is applied to the tread band in the smaller mould. Alternatively the two moulds may be replaced by a single radially adjustable mould. Pins 8 are placed at the illustrated positions prior to application of the tread band and again prior to the application of the carcass. The presence of the pins is stated to prevent the formation of a large crinkle in each of the tread band and carcass (Fig. 3 not shown).

Filed: 1968-09-12
Abstract: 1,208,788. Tape cartridge apparatus. AIWA CO. Ltd. 12 Sept., 1968 [3 Aug., 1968], No. 43350/68. Heading G5R. Magnetic tape apparatus having two sets of heads and transport mechanism for use with small or large types of cartridge has guide blocks adjacent a single insertion entrance adapted to displace the transport mechanism for the small cartridge when a large cartridge is to be inserted. The displacement may be effected by push-buttons or levers, by a shutter closing the entrance or by the act of inserting a large cartridge. When a small cartridge, e.g. a reel-to-reel cassette, is inserted it passes beneath projections 32 on movable guide blocks 24, 25 and is slid in grooves 48 in the blocks to engage slides 11 pivoted on rods 10 upstanding from a plate 2 carrying the transport mechanism and coupled to the chassis 1 by parallelogram links 5. The plate 2 is thereby raised to engage the cassette with capstans 16 and spindles 13, 14, the plate being latched until the end of play when it is released and the cassette ejected (not detailed). When a large cartridge, e.g. endless 4- or 8- track, is inserted it engages the projections 32 to laterally displace the blocks 24, 25, thereby causing stopped grooves 33 and pins 34 to retract the slides 11 from the path of movement of the cartridge; and to move the blocks inwards, whereupon inclined surfaces 35 on the blocks engage pins (23, Fig. 6, not shown) on a pivotal plate 20 carrying the head and pinch rollers 18, (19) for the small cartridge, to retract the assembly below the deck. If the cartridge is 4-track, a pinch roller 45 is raised (not detailed) to coact with capstan 47, and if 8-track a spring-urged link 36 engages in the standard notch so that the cartridge's pinch roller coacts with the capstan 47. The head 44 is trackchanged by mechanism 46 (not detailed) and the drive motor switch 40 operated upon insertion of either type of cartridge by a sensing mechanism 38, 39. In a modification, a roller shutter is opened to varying amounts according to the size of cartridge to be inserted and engages a plate connecting the two guide blocks to shift them or not (Figs. 7-9, not shown), thereby setting the same mechanism as before.
