Title: High voltage protection circuit
IPC: H04N3/20
Filed: 1975-01-22
Abstract: 1493464 Cathode-ray tube circuits RCA CORPORATION 22 Jan 1975 [31 Jan 1974] 2802/75 Heading H4T [Also in Division H2] The display on the screen of a television cathoderay tube is interrupted or modified when the EHT voltage exceeds a predetermined level, e.g. a level at which X-ray emission or component damage is likely to occur. As shown in Fig. 1, D.C. operating voltage for the vertical deflection generator and amplifier 15 and/or for the video processing circuits 30 is derived by rectification of the voltage across a winding 20c on the line output transformer 20 by means of rectifier 35. Rectifier 35 is shunted by an oppositely poled silicon controlled rectifier (SCR) 36 which is selected to have a "breakover" voltage such that when the voltage developed across the EHT winding 20b exceeds a predetermined level the voltage developed across SCR 36 exceeds this breakover voltage. SCR 36 then conducts and disrupts the operation of rectifier 35 so that the operation of the deflection generator and amplifier 15 and/or the video processing circuit 30 is impaired. The display on the tube screen is thus interrupted or modified and acts as an indication to the viewer that excessive voltage is being generated. The rectifier 35 and SCR 36 preferably comprises an integrated thyristor-rectifier (ITR). As an alternative the D.C. operating voltage may be obtained by rectifying an input reactor voltage where the vertical deflection generator is of the kind described in Spectification 1,260,375.

Title: Improvements relating to Artificial Hands.
Inventor: ROBINSON ENOS
IPC: A61F2/58
Filed: 1918-02-20
Abstract: 123,180. Robinson, E. Feb. 20, 1918. Limbs, artificial.-The joints at the inner ends of the centre and outer phalanges of three-joint fingers or the two joints of thumbs are both provided with mechanism for automatically locking the fingers or thumb in the bent position and for releasing the joints of any one finger either simultaneously or successively by the operation of a single cord or lever. In the construction shown in Fig. 1, the centre and outer phalanges are formed with ratchet teeth b engaged by spring pawls d on the adjacent phalange. An operating cord f may withdraw both pawls simultaneously or may be knotted as shown to withdraw them successively. Coil springs g straighten the fingers automatically when the pawls are withdrawn. A chain t may be used if necessary to produce the bending movement of the fingers. In a modified construction, the pawls are operated by a rigid rod in lieu of the cord f. Fig. 5 shows a modified construction in which the bending movement of the fingers rotates cams i against the action of springs k. The cams are rotated until they no longer engage with the phalanges and then slip backwards into a position in which they re-engage and lock the fingers until released by operation of the cord j. In applying the invention to artificial fingers, the locking-mechanism is fitted between a pair of parallel metal plates l, Fig. 2, forming the base-work of each phalange. Mouldings, carvings, or stampings are then secured to these plates to build up the fingers to the desired shape. Strips of india-rubber may be fitted to the fingers to secure a firm grip, and the tips may be fitted with magnetized steel plates z, Fig. 1.

Patent GB-451236-A (GB)
Title: Improvements in or relating to the manufacture of rubber bonded abrasive articles
Filed: 1935-02-01
Abstract: A rubber bonded abrasive article is made by mixing abrasive grains and an aqueous dispersion of rubber (e.g. containing vulcanizing agents), drying, preferably to 5 to 10 per cent moisture, and compacting the mix by passing it between rolls spaced apart sufficiently to prevent crushing of the abrasive grain.  The mix is preferably disintegrated before compacting. Further solid rubber may be incorporated with the mix.  In an example, 888 parts of alumina grit are wetted with 70 parts of a 10 per cent lead acetate solution. To this is added a mixture of 35 parts of sulphur and 175 parts of a 40 per cent artificial aqueous rubber dispersion.  After mixing, a paste of 7 parts of magnesia and water is mixed in, the mixture dried to 7 per cent moisture, disintegrated, screened and sheeted between calender rolls.  A disc is then cut and part cured at 5000 lbs. per sq. in. at 300 DEG  F. for 1 hour, the cure being completed in an oven for 16 hours at 320 DEG  F.  Another example shows the addition of smoked sheet rubber to a mix during calendering.  Specification 360,482 is referred to.

Title: Improvements in or relating to machines for attaching heels to boots or shoes
IPC: A43D79/00
Filed: 1939-02-03
Abstract: 525,959. Heel-attaching machines.' BRITISH UNITED SHOE MACHINERY CO., Ltd., KESTELL, T. A., and BARCLAY, W. R. Feb. 3, 1939, Nos. 3580 and 1816/40. [Class 17 (i)] Relates to machines of the kind d described in Specifications 451,410 and 475,579. Provision is made for offsetting the longitudinal central line of the heel, and the operator is relieved of the effort of closing the band clamp on the shoe, a spring energized near the end of the cycle being released by a latch to close the clamp during the early portion of the depression of the treadle of the machine. The latch is prevented from releasing the shoe should it be desired to attach a top-lift in a second machine cycle. The shoe positioning means are raised by a cam engaged by a roll on the fastener loading device, and latched in raised position, the latch being released by the operator or automatically by movement of the jack to operative position. A bracket 27 slides vertically on ball bearings 29 and carries a shelf to which is dove-tailed a support 33 adjustable forwardly and rearwardly by rack and pinion. The clamping band 5 is carried by a member 17 slidable transversely and adjusted by a lever 55, the movement of the lever being limited by stops 61 which serve to lock the slide in adjusted position. The clamp is raised by the engagement of a roll on the fastener loading device with a cam 65. It is held in its upper position to facilitate work positioning by a latch 69 engaging one arm of a bell-crank lever 67. The lower position of the clamp is determined by an adjustable link 75 supported by a bellcrank lever 77 having a stop 81. A torsion spring 83 prevents sudden fall of the clamp support. The latch may be released by a link 105 actuated by a pivoted member 109 having a pawl 113 engaging a hardened plate on an extension arm 99 of the jack 91. Alternatively, it may be released by a handle 87 linked to a forwardly extending arm of the lever 67. The rod 155 which opens and closes the band clamp, as described in the prior Specifications, is pivoted to a bell-crank lever 157 pivoted to a rod 161 urged upwardly by a spring 167, the lever co-operating with a latch plate 173 on a rod 171 connected to the machine treadle. The rod 171 carries a pawl 181 actuated by a rock-shaft 189 on depression of the treadle as described in Specification 23021/11, [CLass 171, releasing the band clamp to grip the shoe early in the depression of the treadle. If the shoe is not properly positioned, a handle 191 is actuated to release the clamp. To prevent the band clamp opening at the end of the cycle when a top lift has to be secured, a bell-crank lever 197 carries a pivoted block 201 retained in either of two positions by a spring poppet and having a cam face cooperating with a roll 206 on the bar 171. A swing plate 209 carrying both heel and toe lift holders is linked to the bell-crank lever to allow the clamp to open after the attachment of the toplift.
