Abstract: 1,082,019. Cutting webs. A. M. DICKINSON (BOOKS) Ltd. Feb. 23, 1966 [Nov. 23, 1965], No. 47527/64. Heading B4B. [Also in Division B6] In a machine for making book sleeves (see Division B6), superposed and united strips of plastics film and paper are cut into short lengths to provide the sleeves, by a guillotine unit 23 which is oscillated in the direction of the feed of the strips by a motor (22, Fig. 1), change gears, an adjustable eccentric (24), and a connecting rod 25, and the unit is adjustable to cut varying lengths from the strips. The unit 23 is oscillated about a shaft 27 in fixed bearings 27a on a frame 28 having two brackets 29 which support rotatably two plates 30 joined by a link 34. An arm 31 fixed on the shaft 27 moves downward when the unit 23 is moved forward, to depress a lever 32 fixed on one plate 30 causing both plates to rock clockwise. The upper end of the unit 23 carries a fixed blade 35, and a movable blade is carried by two vertical rods 37 having rollers 38 on their lower ends and resting on the plates 30. The rods 37 are urged downwardly by coil springs 37, and the plates 30 are urged upwardly by springs 33. Thus, when the rod (25) moves the unit 23 forwardly (Fig. 1), the arm 31 rocks the plates 30 clockwise, and the rods 37 and cutter blade 36 move upwardly to sever the united strips. The cutting edge of the blade 36 is inclined along its length, and cuts with a scissors action.

Title: Drive mechanism
IPC: F16D67/02
Filed: 1962-12-20
Abstract: 1,010,560. Washing machines. PHILCO CORPORATION. Dec. 20, 1962 [Dec. 26, 1961], No. 48099/62. Heading D1A [Also in Division F2] A first one of two output shafts is permanently connected to a reversible motor, and the second output shaft is connected to the motor by a one-way driving and associated brake arrangement such that the second shaft is driven for one direction of rotation of the motor and is braked when the motor is operated in the reverse direction. As applied to a washing machine an input pulley 54 is reversably driven by an electric motor 71 and is fact with a shaft 36 coupled to an agitator 42. The input pulley 54 is formed with lugs 55, 56 engageable, according to the direction of rotation, with inturned ends 62, 63 of a clutch band 61 which frictionally engages the inside surface of a depending flange 67 of a drum 65. Drum 65 is fast with a cam 82 which has vertical abutment surfaces 83 and helical cam surfaces 84 co-operating with corresponding surfaces of a cam 85 the upper surface 91 of which engages the lowermost of a stack of brake discs 48 which are splined alternately to a fixed tubular column 22 and a hollow rotatable shaft 33 which is fast with a basket 15 of the washing machine. In operation the agitator shaft 36 is driven for both directions of rotation of the motor 71 and for rotation of the input pulley 54 in the direction of the arrow shown in Fig. 4, the lug 55 of the pulley engages the end 62 of the clutch band 61 and tends to disengage the clutch against the pressure of a spring 70 extending between the ends of the clutch band. The clutch is thus lightly engaged and partially rotates the cam 82, shifting the cam 85 axially through the co-operating helical surfaces 86 and compressing the brake discs 48 to station the shaft 33. For the opposite direction of rotation of the motor, the lug 56 of the input pulley engages the head of a stud 66 compressing a spring 66 extending between the head of the stud and the end 62 of the clutch band, so that the tendency of the input pulley to disengage the clutch band 61 is opposed by both springs 66, 70, so that the clutch remains firmly engaged and drives the cam 82, which through the vertical abutting surfaces drives the cam 85, which is in its lowermost position releasing the brake discs, and driving the shaft 33 by means of a spline connection between the cam 85 and this shaft. The basket 15 is therefore driven. When the motor 71 is de-energized following spinning of the basket 15, the basket will continue to spin under its own inertia. The shaft 33 will thus tend to drive the pulley 54 and the motor 71, which results in expanding of the cam 82, 85 axially and the application of the brake to assist stationing of the basket.

Abstract: 1,144,306. Disc brakes. AUTOMOTIVE PRODUCTS CO. Ltd. 15 Nov., 1966 [23 Nov., 1965], No. 49685/65. Heading F2E. In a vehicle disc brake, a fixed support 1 is mounted on a fixed part of the vehicle frame and is provided with a flat platform 5 on which slides a sliding member 7 provided with an opening to receive a peripheral portion of the brake disc brake friction pads 14, 15 being adapted to be urged into frictional engagement with a brake disc, suitable for mounting on the transmission of the vehicle, by means of a ball and ramp mechanism 24 when the brake is actuated by means of an operator controlled lever means 32, the sliding member 7 being guided for rectilinear movement relative to the platform in a direction perpendicular to the plane of the brake disc by three pins 8 carried by the platform and extending through slots 9 in the sliding member. Movement of the arm 32 causes rotation of a rotatable disc 21 carrying the arm and rotation of this disc 21 in relation to the other disc 20 which is held against rotation causes the balls 24 to ride up in the inclined ramps. An automatic adjusting mechanism is incorporated in the brake in the form of a toothed ratchet-wheel 36 formed on an inner sleeve 34 having a screwed connection with a threaded rod 35 which bears against the metal backing plate 16 of the brake pad 14. Three pawls 37, each pivotally mounted on a projecting end of a stud 33, are urged into engagement with the teeth 36a on the wheel 36. Surrounding the inner sleeve 34 is an outer sleeve 25 such that the sleeves and the threaded rod together provide a thrust member which is axially displaced from a retracted position by the ball-andramp device upon swinging movement of the arm to effect a braking operation, the mechanism being returned to the position of rest by the action of a spring 38, the working part of the automatic adjusting mechanism and the ball- and-ramp mechanism is protected by means of sealing boots 41, 42 of elastomeric material. The automatic adjusting mechanism operates in such a manner that if no adjustment is required the angular swinging movement of the arm 32 will be insufficient to cause the pawls 37 to engage further teeth on the ratchet-wheel 36, the pawls merely riding up and down the flanks of the engaged teeth. Should pad wear be sufficient to require adjustment of the brake, the angular swinging movement of the arm 32 will increase and such increased movement causes the pawls 37 to engage further teeth so that when the arm is released and during its return movement to the rest position the inner sleeve will be rotated to cause outward movement of the threaded rod 35 by an amount corresponding to the wear.

Abstract: 1,149,959. Digital data storage. FUJITSU Ltd. 9 Nov., 1966 [9 Nov., 1965], No. 50326/66. Heading G4C. In a system for reading binary signals recorded on a magnetic tape, disc or drum in the form of frequency or phase modulation, the output of the read head is supplied to peak detector 2 which provides an output pulse at the start of each bit period and an additional pulse in the centre of a bit period for a binary "1". Monostable circuit 6 is turned on by a pulse from detector 2 and remains on for a period which is determined by the value of the preceding bit. The leading edge of each "on" pulse from circuit 6 is used as a clock pulse at terminal c. A further monostable circuit 7 can only be turned on by a pulse from detector 2 when circuit 6 is "on", i.e. by a peak representing a binary "1". A bi-stable circuit 13 is triggered by the pulses from detector 2 in accordance with the state of circuit 7 to provide a data output at terminal b. Whenever a binary "1" is detected, the charging time of capacitor 18 is reduced in the next bit period so that circuit 6 remains on for # of the nominal bit period instead of the normal <SP>6</SP>/ 8 . The arrangement is said to improve discrimination when the read signal is subject to time axis distortion.
