Title: Black level control circuit for a television receiver
IPC: H04N5/16
Filed: 1964-08-18
Abstract: 1,057,475. Controlling television picture signals HAZELTINE CORPORATION. Aug. 18, 1964 [Sept. 18, 1963], No. 33690/64. Heading H3Q. In a television receiver using a keyed A.G.C. system with additional means for stabilizing the black level and limiting beam current in scenes of high average brightness as in Specification 1,057,474, the A.G.C. is keyed to the sync-tip level instead of the blanking level as in Specification 1,057,474. In Fig. 1, the video amplifier 13 is connected to the cathode of the picture tube via a resistor-capacitor network 24/25 (or other network as described in Specification 1,057,474) which is also used to feed an A.G.C. tube 28 gated by the tips of the sync pulses by applying flyback pulses from the line deflection circuit 18. A signal representing the average scene brightness is developed by the cathode-ray beam current flowing through resistor 24 and this is applied to the grid of tube 28 to modify the A.G.C. voltage accordingly. The net effect is that the A.G.C. voltage represents the average scene brightness while the black and other levels are held constant. In an alternative circuit (Fig. 3, not shown) the average brightness signal is applied to the A.G.C. tube by the beam current flowing through resistors 36, 37 and the black-level compensating signal is taken from the screen of the videoamplifier to the cathode of the A.G.C. tube.

Title: Artificial furs
IPC: D04B9/14
Filed: 1965-08-10
Abstract: A rib fibre pile fabric is produced on a circular machine by feeding the fibres to a doffing roller at a rate less than that at which the needles are capable of taking a maximum amount of fibres and rotating the roller by more than one rotation during the fibre gathering by a selected group of needles such that some needles receive more fibres than others.  The accummulation of fibres on the roller prior to the selected needles taking fibres causes the initial needles to receive a maximum or greater amount larger than that received by the following needles.  Needle selection can be achieved by pattern wheels and two fibre feeding mechanisms each associated with needle selecting mechanism may be positioned before each feeding station of a multifeed machine. Specification 893,506 is referred to.

Patent GB-887246-A (GB)
Title: A spring looping machine
Inventor: ASHLEY-WING HERBERT HENRY
IPC: B21F35/02
Filed: 1959-10-12
Abstract: 887,246. Jigging conveyers. FRIDEN Inc. Oct. 12, 1959, No. 34564/59. Class 78 (1). [Also in Group XXII] In a spring looping machine, axially aligned springs 67 with unlooped ends are fed to a conduit 50 from a spiral ramp in a vibratory hopper feeder 35, vibrated with a rotary as well as a vertical motion by electromagnet means, the amplitude of the vibration being adjustable. The conduit 50 discharges, through a demagnetizing coil 245, into a downwardly-inclined trough 51 secured to a plate 52 vibrated in a plane perpendicular to the trough 51 to impart rotary motion, about their axes, to the springs 67 as they pass down the trough 51. A spring 67 thence passes into an aligned diametrical bore 66 in a turret 64 rotatable on the plate 52, a latch 120 on a pivoted arm 115 being rocked by a stud 76 on the turret 64 to allow only one spring to pass into the bore 66. The spring 67 passes through the bore 66, still rotating due to the vibration of the plate 52, until it abuts shoulders, flanking a recess 71 in an anvil 69 on the turret 64 and arranged so that one full turn of the spring projects beyond the bore 66. A loop-forming tool 187 on a shaft 189 is then rocked by a cam 203, Fig. 4, to form the end loop in co-operation with the anvil 69, a switch 221 operated by the cam 203 stopping vibration of the plate 52 during the loop forming. The tool 187 is then raised and the turret 64 rotated 90 degrees, by a cam 131 rocking a lever 139 moving a rod 151 and crank means, so that the spring 67 falls into a bore 82 in a turret 80 which is rotated 90 degrees by the rod 151 so that the spring slides into a bore 92 in a turret 90, also operated by the rod 151 and cam 131. A tool 188 is rocked by the cam 203 to form a loop at the other end of the spring which now projects from the bore 92. The turret 90 is then rotated to discharge the spring, now looped at both ends. Air injector means may be provided to blow the springs through the bores of the turrets. A counter 180 may count the springs. In a modification, Figs. 16, 17, vibration is applied only to the first and last turret means 364, 390. The bore 366 of the turret 364 is formed in a bar 362 mounted on leaf-springs 379 and bar 360 on the turret 364 and vibrated by electromagnet means 377. The bore 392 in the turret 390 is likewise vibrated independently of its turret. Compressed air is supplied to the bores by jets from passages 435, 445-448, controlled by valves, in a manifold 401, actuated by a cam 425.

Title: Improvements in and relating to apparatus for feeding sheets such as bank cheques
IPC: G06K13/063
Filed: 1961-09-27
Abstract: 928,000. Sheet-delivery apparatus. NATIONAL CASH REGISTER CO. Sept. 27, 1961 [Nov. 1, 1960], No. 34667/61. Class 100 (1). Apparatus for delivering sheets such as bank cheques to a stack comprises co-operating feeding and pressure rollers 115 and 116 for feeding the sheets in a forward direction and co-operating feeding and pressure rollers 123 and 119 for feeding the sheets in a reverse direction, the pressure rollers 116 and 119 being mounted on a common spring-urged plate 117 rockable about the point 18, whereby the plate is rocked in a clockwise direction (as shown) when the sheet is being fed forwardly by rollers 115, 116 so as to dissociate the reverse feeding rollers 123, 119, whereas, when the trailing edge of the sheet has passed beyond the forward feeding rollers 115, 116, the spring rocks the plate in a counterclockwise direction to reassociate the reverse feeding rollers 123, 119 whereby the sheet is fed in the reverse direction. The sheets are fed along a guide 104, from a parent machine imprinting the sheets with magnetic characters, by co-operating rollers 107, 108. The feed rollers 107, 115 and the pressure rollers 108, 116 are formed from rubber and nylon, respectively. The pressure rollers are spaced from their associated feed rollers to prevent undue wear and are provided with side flanges, Fig. 4 (not shown), overlapping the peripheral surfaces of their associated feed rollers, so that a sheet passing between a pair of rollers is curved and forced into engagement with the feed roller. The reversing rollers 123, 119 are made of nylon and feed a sheet downwardly between co-operating rollers 115, 126 to a switch 131 which deflects the sheet to an upper or lower stack. The switch is positioned by linkage 135 actuated by a solenoid 106 responsive to the parent machine. The sheet is fed along a guide 143 by co-operating feed and pressure rollers 146 and 147. The roller 146 has a flat area 180, whereby the sheet is moved intermittently until it engages a constantly rotating roller 148, and is set at an angle so that the sheet is moved laterally to register it against the back plate 99 of the apparatus. The lower guide plate 144 is cut away as shown in dotted outline in Fig. 6 and the lower right-hand side of the back plate 99 bent rearwardly, so that a sheet is rotated to disengage the lower guide plate 144 and fed along the top of the stack to abut front stops 153 of a collapsible table 149 by the roller 148. The table is mounted on cross-legs 150, 151 urged upwardly by spring means. A sheet deflected to the lower stack is fed along a guide 157 by rollers 107, 108. A detector, comprising an arm 154 attached to a micro-switch 156, is located in the guide 143 and is operated each time a sheet passes thereover to deactivate the parent machine, so that should a sheet become jammed in the guide the switch 156 remains open to prevent further operation of the parent machine until the fault is cleared.
Patent GB-487386-A (GB)
Title: Improvements in and relating to shutter mechanism for photographic cameras
IPC: G03B9/70
Filed: 1936-12-17
Abstract: 487,386. Shutters for photographic cameras. DECKEL, F., (trading as DECKEL, PRAZISIONSMECHANIK UND MASCHINENBAU, F.). Dec. 17, 1a36, No. 34720. Conventiondate, Dec. 21,1935. [Class 98 (i)] In a camera with combined film feed and shutter setting, as for example in Specification 463,769, the shutter requires presetting for all exposures including " B " and " T " and is provided with a lock which prevents actuation of the shutter release when the shutter is not set. The setting ring 3 is moved by a handle 6 against a spring 4 simultaneously feeding the film forward, and is held by a spring loaded detent lever 7 engaging a notch 8. When the shutter is not set, the lever 7 lies in a recess 11 and prevents actuation of the lever 9 by engaging an arm 12 thereon. A pin 15 on the push pawl 14 of the adjustment ring 16 is shortened so that it no longer engages this ring for B " and " T " exposures. In making " B '' exposures, a lever 18 is caused by a spring 19 to bear with its arm 20 against a pin 21 on an intermediate lever 22. The lever 22 which is acted on by a spring 24 transmits to the lever 9 the pressure of the release cable in the nipple 25. A projection 26 on the lever 18 moves into the path of a stop 27 on the setting ring. A finger 28 on the lever 18 engages the cam surface 29 of the ring 16 in order to hold the lever 18, 26 clear of the stop 27 during the pre-determined shutter exposures. The escapement mechanism 31 is influenced by the curve 33 of the adjusting ring 16 so that, for Band T exposures, the anchor 34 is disengaged from the balance wheel 36. When a " bulb " exposure is to be made, the projection 26 drops into the path of the stop 27 and the detent lever 7 is released from its locking position. When the release lever is pressed down, the sectors are opened and the stop 27 engages the projection 26 to hold them in that position. When the release lever is returned to normal position, the intermediate lever 22 is moved by its spring 24 and the pin 21 withdraws the stop 26 allowing the sectors to close. For time exposures, a further lever 38 is present and is mounted on the same pivot as the lever 18. It lies adjacent a pin 41 on the lever 22 and possesses a projection 42 similar to the projection 26. After the first release operation, the lever 38 and projection 42 are moved to engage the stop 27, the second release operation allowing the ring 3 to run down.
