Patent GB-406671-A (GB)
Abstract: 406,671. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Green, C. W.; 106, S. 4th Avenue, Ilion, New York, U.S.A.) Aug. 31, 1932, No. 24282. Convention date, Aug. 31, 1931. [Class 106 (i).] Machines with several item-value totalizers; printing totals.-In a cash register having printing mechanism including a pivoted printing frame movable relatively to type elements to print a total from a selected totalizer, means are provided automatically to lock all totalizer type elements against movement when the printing device is moved relatively to the type. The invention is of general application, but is described as applied to the key set and operated cash register disclosed in Specifications 135,465 and 157,824, [both in Class 106 (i)]. The printing mechanism (i.e., the platen 407, the record strip-and the inking ribbon) are mounted so as to be rockable about a rod 100 to position the platen for printing from the item type-wheels 200 or from either of two totalizers 200A, 200B. In order that the totalizer wheels may not be rotated by friction as the platen is rocked, they are locked whenever the platen is moved from its normal position over the type-wheels 200. For this purpose, a member 300 is loosely mounted on the main shaft 25 and is rocked clockwise, when the platen is moved from normal position, by a pin 310 that is carried by the printing frame and bears against a cam surface 303, 304 on the member. The rocking movement is transmitted from the member through a rod 306 to the transfer arms 220 that in turn rock the pawls 205 into locking engagement with the totalizer pinions. When the platen is returned to normal position, a shaft 442 on the printing frame engages an arm 312 of the member to return the rod 306 and release the totalizer wheels.

Abstract: 1366736 Character recognition systems; data scanning systems INTERNATIONAL BUSINESS MACHINES CORP 4 Sept 1972 [6 Jan 1972] 40853/72 Headings G4R and G4M [Also in Divisions H4 and H1] A scanning system employs a diffuser in the path of radiation incident on the scanned object and of radiation reflected from the object. The radiation source is so positioned that the radiation sensor receives only diffusely-reflected radiation if the object is flat. Because the object may not be flat, for example as in the case of a mail envelope, some specularly reflected radiation may be directed towards the sensor. The diffuser reduces the intensity of the specularly reflected radiation to below that of the diffusely reflected radiation in order to prevent improper operation of, for example, a character recognition system or facsimile system fed by the sensor. The diffuser may be a ground glass screen with the ground face very close to or touching the scanned object.

Filed: 1962-10-31
Abstract: Chloroprene polymers are prepared in aqueous emulsion in the presence of 0.01 to 0.04 part mole, per 100 parts by weight of monomer of a dialkyl xanthogen disulphide, the alkyl groups of which contain from 1 to 8 carbon atoms, at a temperature of from 15 to 25 DEG C., a pH of from 5 to 11, and in the presence of a catalyst system comprising per 100 parts by weight of monomer: (a) between 0.00065 to 0.0013 part mole of an organic hydroperoxide. (b) between 0.1 to 0.3 part by weight of an inorganic water-soluble persulphate and (c) at least 0.05 part by weight of an inorganic water-soluble hydrosulphite and/or pyrosulphite, with the proviso that (a) and (b) are added separately to the polymerization system before polymerization is initiated, polymerization then being initiated and maintained by the addition of (c).  The term "part mole" means that the molecular weight of the particular disulphide used is calculated in the same units as the amounts of monomer. Preferred hydroperoxides are those with the formulae <FORM:0952156/C3/1> wherein X, X1, and X2 are independently selected from the group consisting of aliphatic acyclic, aliphatic cyclic, aryl, alkoxyl and aralkyl radicals. Another group of suitable hydroperoxides is the ketone peroxides. The water-soluble inorganic persulphates are preferably the sodium, potassium or ammonium salts of persulphuric acid. Sodium hydrosulphite is the preferred water-soluble inorganic hydrosulphite. The polymerization is carried out in aqueous emulsion using any of the conventional emulsifying agents for chloroprene polymerization. The chloroprene may be polymerized with up to 10% by weight of other vinyl monomers e.g. styrene, vinyl toluene, vinyl naphthalene, acrylic and methacrylic acid esters and nitriles, and conjugated diolefinic compounds such as 1, 3 butadiene, isoprene and 2, 3-dichloro-1, 3-butadiene.

Abstract: 1,247,842. Cathode-ray tube circuits. PLESSEY CO. Ltd. 4 Oct., 1968 [15 Sept., 1967], No. 42240/67. Heading H4T. The magnitude of a variable shunt impedance means connected in parallel with the line deflection coils of a television receiver is varied as a function of the E.H.T. voltage. Thus, as the beam current of the tube increases with increasing brightness the resulting drop in the E.H.T. voltage produces a reduction in the magnitude of the shunt impedance and the increased shunting effect reduces the drive in the line deflection coils so that the length of the lines (picture width) remains substantially constant. In the embodiment described the variable shunt impedance comprises saturable core reactor 6 the output coil 8 of which is connected in parallel with the line deflection coils 9 and the control winding 5 of which is in series with the H.T. supply to the line output valve 3, from which the E.H.T. is derived via a further winding (not shown), via the efficiency diode 2. Thus, when, due to increase in brightness, the beam current increases the resulting drop in the E.H.T. voltage at the cathode 4 of diode 2 increases the current flow through windings (and valve 3) such that the impedance (inductance) of winding 8 is reduced proportionately. The shunting effect is therefore increased and the parameters are so arranged that the deflection field produced by the coils 9 varies as a function of the E.H.T. voltage. The invention is particularly concerned with colour television receivers and it is assumed that known EHT voltage, stabilizing devices (e.g. a shunt triode), if present are not effective at the beam current levels considered. An advantage of the invention is that such a shunt stabilizing triode, which generates X-rays and is therefore a hazard to health may be dispensed with if desired. .

A dry, air-cooled transformer, Fig. 6, has concentric high-voltage and low-voltage windings 18 and 20 carried by laminated core sections 16 (14, Fig. 1), each winding comprising copper or aluminium strip or foil 30, 42. The turns 30 are insulated by an enamel coating 40, e.g. epoxy resin, disposed on the strip, are wound on a plastics tube 32, and are encapsulated in cast solid insulating thermosetting material 34 e.g. epoxy resin with a filler of beryllium aluminium silicate, said material 34 having the same coefficient of thermal expansion as the strip 30. The turns 42 are insulated by an enamel coating or insulating sheets 44. A glass tape 48 surrounds the winding 20, or, if the transformer is to be fluid-cooled or disposed under ground, the winding 20 may also be encapsulated with the same material. A casing (54, Figs. 1, 2) may have a corrugated base, and aluminium cooling ducts (60, Figs. 5, 3) may be provided in the windings. To reduce voltage stress the encapsulated winding 18 is coated with a conductive varnish (70) and a stress grading paint (72, Fig. 4) containing silicon carbide. In another embodiment (Figs. 7 -11) the low-voltage winding (90) is wound on a tube (92) and is encapsulated in cast insulation (100), and the high-voltage winding (102) is wound on the insulation (100) and further insulation (110) is cast around the winding (102). A conductive shield is embedded in the insulation (100) and a waterproof coating (111), e.g. unfilled epoxy resin, may be applied to the insulation (110). The transformer may be disposed in a metal casing (88) containing coolant (89), e.g. a gas SF6, or askaral, oil, water with a rust inhibitor. Alternatively, in the latter case, the core may contain a waterproof coating. If liquid cooled, the outer surface of the encapsulated winding (120) may be roughened to create nucleate boiling. In a further embodiment (Fig. 12) a dry transformer having encapsulated high- and low-voltage windings has its insulated high- and low-voltage leads (148, 142) provided with bayonet connectors (155, 157) for connecting to the primary and secondary circuits.

Abstract: 1,071,940. Film feed mechanisms. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 12, 1965 [Oct. 15, 1964], No.43211/65. Heading G2A. In a photographic camera particularly for taking X-ray photographs on an intermittently movable film, an electric motor is switched on and a delivery spool 4 driven. Film 3 from the spool is fed through a tunnel 17 to a driven roller 18 around which it is guided by a curved guide 19, then through the exposure gate 14 to pass between a transport roller 21 and a tension roller 22, and then guided by guide 24 around a roller 23 to open contacts 25, 26 of a switch 27. This causes a lamp (48) Fig. 2 (not shown) to light up, indicating the film is correctly positioned for exposure, and causes a relay (37) to be deenergized, thereby de-energizing relays 42-45 and switching off an electromagnetic spindle coupling 28, so that springs 49, 50 swing the guides 19, 24 to the dotted line positions, cams 46 are free to rotate and roller 23 stops rotating. An operating switch (51) is closed to switch on the motor (39) by which the cams 46 are rotated so that a pressure plate 29 clamps the film in the exposure gate 14, continued rotation of the spool 4 causing a loop 30 of the film to be formed. Further rotation of the cams releases the pressure and allows the loop 30 to be fed by the roller 21, thus forming a loop 31 which, when large enough, closes contacts 32, 52 to energize a relay (53). This energizes the spindle coupling 28 and the roller 23 feeds the film through a tunnel 33 to a take-up spool 5, and also opens a switch (55) to prevent re-energizing of relays 42-45. While the loop 31 is being fed to the take-up spool, the cams 46 rotate to raise the pressure plate 29 and clamp the film in the gate 14 for a further exposure. The pressure plate is lowered and the newly exposed film advanced to enlarge the loop 31 which has almost completely disappeared. The roller 23 rotates continuously since a contact (56) is closed by the relay (53) to bridge the contacts, 32, 52. When the trailing end of the film has passed between the contacts 25, 26 the switch 27 is reclosed and the light 48 goes out, indicating that more film is required. The spools 4, 5 are provided in magazines 6, 7 which are rendered light-tight on removal from the camera by means of slides 12, 13.
