Patent GB-1434890-A (GB)
Title: Business printing machine
IPC: B41J33/516
Filed: 1974-05-22
Abstract: 1434890 Ink ribbon mechanisms VICTOR COMPTOMETER CORP 22 May 1974 [17 Sept 1973] 22864/74 Heading B6F A printer has an ink ribbon 24 fed via guides 25 between spools 21 which are on a deck 11 pivotally supported at 13; one of the ribbon spools 21 is driven via its associated ratchet wheel 17 engaged by a pawl on oscillating arm 64 and a vibrator mechanism pivots the deck 11 from a lower inoperative position to first or second upper operative positions. Vibrator mechanism.-As shown in Fig. 4 a link 29 is pivoted at 29 to lever 33 and has its free end resting on cam 35 having two tracks of different diameter, each track having a dwell 37, 38. In the printing of a line cam 35 rotates once anti-clockwise and then reverses back to its starting point. If solenoid 47 is not energized as shown, the link 29 follows the smaller diameter track causing the link to rise as far as the phantom position. When the solenoid 47 is energized the link follows the larger diameter track by means of extension 39 and so produces a greater range of movement. The link 29 is connected to the deck 11 by stud 28. The different ranges of movement permit the use of a two colour ribbon. Ribbon feed and reversal.-During clockwise rotation of the shaft 36, cam 52 or cam 51 is also rotated, so rocking a bell-crank 54 to move a slide 59. The slide 59 in turn carries a pin 63 engaging one of the two notches 65 in pawl arm 64. Thus oscillation of the slide 59 indexes one of the wheels 17. When the supply spool is emptied, the take-up spool will no longer rotate and thus, at the next feed stroke of the arm 64, springs 66 guide the arm 64 so that the pin 63 engages the other notch 65 thereby reversing the drive to the spools..

Abstract: 424,007. Fuzes for bombs. VICKERSARMSTRONGS, Ltd., and SWIFT, T. R., Vickers House, Broadway, Westminster. Aug. 17,1933, No. 23030. [Class 9 (i)] The wind vane 4 of the fuze of a bomb intended to be dropped from aircraft is provided with a rim 5 to increase the inertia of the wind vane to retard its rotation to delay the arming of the fuze. The firing-pin 8 is connected by a shear wire 14 to a thimble 7 on which the wind vane 4 is screwed ; and these parts are locked somewhat as described in Specification 287,619, [Class 9 (i)], by a transverse tapered pin 6, which passes through a hole in the firing- pin and elongated slots 13 in the thimble, and has a finger 11 in engagement with the wind vane. The transverse pin 6 is held in place by a forked spring 10, and must be pulled out when the bomb is to be dropped alive. When the transverse pin 6 is left on the bomb, additional safety is provided against impact by the slots 13, which allow the thimble to be crushed in and shear the pin 14 without liberating the firing-pin 8 from the transverse pin 6. For further safety against premature impact on the wind vane before this has armed the fuze and fallen off, a screw ring 16 is interposed between the wind vane and the thimble 7 and is attached thereto by loose fitting shear wire 18, which is broken by the premature impact, leaving the firing-pin safe. Reference has been directed by the Comptroller to Specification 26764/11, [Class 9 (i)].

Title: Improvements in or relating to microwave ferrite devices
IPC: H01P1/19
Filed: 1960-07-01
Abstract: 903,537. Waveguide ferrite devices. TELEFUNKEN G.m.b.H. July 1, 1960 [July 31, 1959], No. 23087/60. Drawings to Specification. Class 40 (8). Temperature compensation of a microwave ferrite device, e.g. an isolator, phase-shifter or magnetically controlled resonator, is achieved by providing, in addition to the usual ferrite element, one or more further elements whose cross-sectional dimensions are such that the elements exhibit temperature characteristics opposite to and compensating for the characteristics of the main element. The invention finds application in devices where the shape of the main ferrite element and the strength of the magnetic field are prescribed by considerations other than the elimination of temperature dependence. The additional elements are chosen to provide a temperature deviation equal and opposite to that of the main element at the prescribed field strength.

Title: Improvements in or relating to machines adapted for use in assembling electrical components upon workpieces
IPC: H05K13/04
Filed: 1956-07-30
Abstract: 834,431. Feeding articles. BRITISH UNITED SHOE MACHINERY CO. Ltd. July 30, 1956 [July 29, 1955; Jan. 27, 1956], No. 23392/56. Addition to 802,658. Class 117 [Also in Group XXII] In a machine for assembling electrical components on circuit boards, comparatively flat, disc-shaped capacitors C are carried from a hopper 22 to a shoot 18 leading to the inserting head. The hopper comprises an arcuate receptacle 434 and an inclined circular plate 432 mounted within a wall 430 and formed with eight component receiving recesses 444 shaped as shown in Fig. 23. Under the action of gravity as the plate rotates a component enters a recess and slides up to a wall 450 so that its leads L touch the wall and is then carried by a transfer device, Fig. 29, to the shoot 18 and deposited with its leads straddling a bar 20. A four-armed transfer wheel 490 rotated in timed relation to the plate 432 comprises an axially bored hub 492 and a rotor 496 formed with four axially bored arms each having a rubber pick-up nozzle 572. As each arm 510 reaches an aperture 518 in the hub it is connected to a suction line and a capacitor is lifted from its recess 444 by a nozzle 512 and carried to a position over the shoot 18 whereupon the suction is cut off and the capacitor dropped. A component incorrectly positioned in its recess will be ejected back into the receptacle 434 by camoperated pins projected through holes 522 before the recess reaches the pick-up position. More components are transferred by the wheel 490 than are required and if the shoot is full, a newly deposited component will be blown back into the receptacle 434 by an air jet from a tube 542.

Title: Tune escapement mechanism for speed indicating and recording
IPC: B61L25/02
Filed: 1958-07-22
Abstract: 866,274. Speedometers. REICH, E. July 22, 1958 [July 31, 1957], No. 23482/58. Class 106 (3). in a time escapement mechanism for speed indicating and recording instruments provided with relays or the like controlled by electrical impulses and actuated by a switch adapted to periodically open and close their circuits, the contact-making disc of the switch is secured on the escapewheel shaft of the escape mechanism, the main spring of which is wound up at each impulse by one of the relays, and at a decrease of the tension of the current source by a predetermined value the operation of a moving part of the time escapement mechanism is prevented by the armature of a no-voltage relay. An escapement mechanism 1, Figs. 1 and 3, rotates a shaft 2 carrying a cam disc 4 operating switch contacts 6, 7 to energize an electromagnet 8, Fig. 2, for 0.6 second every second. When the magnet is energized, the armature 9 through elastic arms 16 closes a clutch 11, 10, the disc 10 being rotated in proportion to the speed of the vehicle. During the 0.6 second period, the disc 11 is rotated through an angle proportional to the speed and rotates through claws 37, 38 a brake-drum 19. An abutment 39 on the drum engages an abutment 46 on a gear 14 to turn the latter and move a pointer 31 to a position corresponding to the speed. Recording mechanism for the speed is driven through gears 28, 29, a shaft 53, gear 76 and rack 48. If the speed is the same as during the previous period, the abutments will remain in contact. If the speed is greater the pointer will be moved further by the driving abutment 39. On de-energization of the magnet, a stop 21 on an arm 20 attached to the armature releases a pawl 22 to lock the drum 19, while a stop 40 on an arm 23 attached to the armature releases a ratchet 24 and frees the gear 14. If the speed was less, the pointer will move back under the action of a spring 42 until the abutment 46 contacts the abutment 39. The clutch then being opened, a spring 41 restores the disc 11 to zero position. When the magnet is again energized, the stop 40 locks the ratchet 24 to hold the gear 14 and pointer in position, while the pawl 22 releases the drum 19, which is returned to zero position by a spring 43. The clutch is then closed and the operations repeated. The arm 20 also carries a pawl 68 which rotates a ratchet 69 through one tooth each second, two revolutions a minute. Through gears 56, 57, 58, 59 the ratchet 69 drives a time-indicating pointer, co-operating with a scale 60. Through gears 62, 61, shaft 63, and gears 45, 75, 80, the recording tape is driven from the ratchet 69 as a function of the time. The ratchet 69 also winds the clockwork every second through gears 64, 65. The constant friction of the cam switch on the shaft 2 compensates for thermal expansion. If the electrical operating voltage falls by 30%, a no-voltage relay 67 releases its armature 55, which engages the clockwork balance-wheel 56 and stops the clockwork.

Title: Improvements relating to vacuum braking apparatus
IPC: B60T13/46
Filed: 1934-08-15
Abstract: 436,988. Vacuum brakes. LECLAIR, L. J., BRACKENBURY, A. G., and WESTING- HOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Aug. 15, 1934, No. 23540. [Class 103 (i)] A local venting valve for vacuum brakes which admits air to the brake cylinder through a filter comprises a valve 17 which opens a large communication between the train pipe and the brake cylinder if the filter becomes choked. The valve 17 also serves the purpose of a non-return valve between the train pipe and brake cylinder through which air is drawn on brake release thus ensuring by frequent operation that it shall not become stuck. The operation of the local venting valve comprising a ball valve 13 operated by a diaphragm 6, is the same as that of the valve described in Specification 431,081. If the filter connected to passage 25 becomes choked, preventing admission of air, on brake application, to chambers 9, 14, 5 and the lower chamber 7 of the brake cylinder the valve 17 is raised by the increased train pipe pressure acting on an annular surface 23 of the valve, thus opening a large passage 21 connecting the train pipe and the brake cylinder. The brake cylinder chamber 7 is evacuated, when the brakes are released, past the valve 17 and a valve 16 and also past a narrow space 24 between the valve 17 and the wall of the chamber 14.
