Title: Electrophotography
IPC: G03G15/10
Filed: 1959-09-23
Abstract: 940,242. Electrophotography. HARRIS - INTERTYPE CORPORATION. Sept. 23, 1959 [Sept. 23, 1958 (2)], No. 32393/59. Drawings to Specification. Heading G2H. A liquid developer for an electrophotographic charge image comprises a substantially non- conducting liquid vehicle having dispersed therein finely divided droplets of a solution and/or dispersion of a developer agent which is substantially insoluble in the liquid vehicle, the droplets themselves being substantially insoluble in the vehicle and bearing an electric charge. The vehicle may be of gasoline, carbon tetrachloride, kerosene or preferably the petroleum derivative sold under the trade name Varnolene. The developer droplets may be of a solution of a resin such as an epoxy resin dissolved in mesityl oxide or isopropenyl acetate, a vinyl chloride-vinylidene chloride copolymer dissolved in mesityl oxide, polyisopropenyl acetate dissolved in isopropenyl acetate and a dye or pigment e. g. a magnetic oxide may be included in the resin droplets. Developer droplets comprising a red gravure ink dispersed in varnolene may also be used. Fixing may be effected by heating or after evaporation of the vehicle by treatment of the plate carrying the developed image with a solvent for the electrophotographic layer to soften it, or in some cases depending on the electrophotographic layer the solvent of the developer droplets may effect fixing. The charge formed on the droplets depends on the vehicle-droplet solvent relationship. With a varnolene vehicle an expoxy resin in isopropenyl acetate gives positively charged drops while the vinyl-vinylidene chloride polymer in mesityl oxide gives negatively charged drops. Development may be effected by means of a magnetic brush loaded with or immersed in the developer and this brush also serves as a counter electrode. Apparatus is described (see Figs. 8 and 9 not shown) in which a web of electrophotographic material is fed through a combined printer (contact or projection) and magnetic brush developer unit to a drying drum where the vehicle and solvent from the liquid developer is recovered. The feeding may be continuous or intermittent and web feed metering and operating control devices are also provided. Specification 888, 371 is referred to.

Title: Tracer device for machine tools
IPC: B23Q35/26
Filed: 1957-10-22
Abstract: 853,797. Copy-milling. TRUE TRACE CORPORATION. Oct. 22, 1957 [Oct. 22, 1956], No. 32959/57. Class 83 (3). A tracing machine comprises a stylus 27, bias means 43 acting on the stylus to deflect it, means 74, 77 for sensing the deflection, and reversible means 112, 114 to control the pointof-application of the biasing force. Movement of the tracer controls the machine through two mutually perpendicular valves connected to a ring 18 surrounding a spherical enlargement 16 on the stylus. The stylus tilts about a balljoint 26 seating in a rotatable sleeve 30 carrying the biasing means 43, which can be rendered inactive by locking it in a retracted position by a pin 45 engaging the edges of a slot 38. The ball-joint 26 is connected by a key 62 to the sleeve 30, which can be rotated by wormgearing 55, 105. Tilting of the tracer is. detected by an inclined escape orifice 74, supplied with compressed-air from a source 62a and co-operating with an inclined-face 77 on a block 76 on the tracer. The spacing between. the orifice and the face is adjusted by a screw 86 having an extension 85 bearing on the block against the opposing force of a spring 79. The screw 86 passes through an adjustable conicallyrecessed member 95 which is engaged by a sliding-plate 98 embracing a spherical projection 102 on the tracer. The member 95 thus adjusts the degree of permissible movement of the tracer, and limits the maximum speed of the member controlled. In operation, variation of the space between the orifice 74 and the face 77 is detected in a line 103 connected to a bellows 112. Movement of the bellows adjusts a reversing valve 114 to direct fluid to a motor 107, which rotates the worm-gear 55 attached to the sleeve 30. The bias-means 43 provides a force having components towards and along the template-edge, as shown at 204, 205, in Fig. 6. As the tracer travels from point 200 to the position shown, the motor 107 is operated to rotate the sleeve 30 clockwise, to maintain the resultant force 203 in a direction of about 45 degrees to the tangent. When the tracer reaches the second position (shown on the left), then counter-clockwise rotation is necessary. When the tracer is to travel in the opposite direction, a reversing valve 123 is operated manually. It may be necessary initially to move the tracer manually up to the template T. An alternative biasing means comprises a fluid-operated plunger 160. In a modification, a plain orifice 158, Fig. 2, co-operates merely with the stem 157 of the tracer. In a further modification, a contactor 152, Fig. 5, is moved by the stylus 141 to complete a circuit through a ring 143, or a ring 144, to rotate an electric motor in one or other direction to adjust the sleeve 142.

Filed: 1975-08-08
Abstract: 1514251 Exposure control in photo-copies HOECHST AG 8 Aug 1975 [10 Aug 1974] 33165/75 Heading G2A In a photo-copier the transparency of an original is measured to produce a first signal for controlling the relative speed between the light source and the original and/or between the light source and the copying material, a second signal is generated corresponding to the maximum possible relative speed and if the first signal exceeds the second the illumination intensity during exposure is reduced and the maximum relative speed is used. The intensity may be reduced by means of a diaphragm (11, 12), Fig. 4 (not shown) or by reducing lamp voltage. As shown, as each original is fed into the copier its transparency UF is measured at 2a, 2b, stored at 14, then fed to an amplifier 3 and a comparator 6 as the original in question reaches the exposure station. Amplifier 3 is connected via a controller 4 to a motor 5 which determines the speed of the original and copy material through the exposure station according to UF. Comparator 6 compares UF with a signal UFP corresponding to the maximum speed of motor 5. If U F  > U FP  comparator 6 sends a signal to a reference amplifier 7 which via a controller 8 reduces the voltage of lamp 1. Since lamp 1 is used both for exposure and for measuring the transparency of incoming originals, if its voltage is reduced the change is detected and compensated for by an arrangement 18, 19, 20 which controls a multiplier 17 connected to the photo-sensitive measuring units 2a, 2b.
