Abstract: 1,226,655. Photographic copying apparatus. PITNEY-BOWES Inc. June 28, 1968 [June 30, 1967], No.31032/68. Heading G2A and G2H. A "desk top" electro-photographic copying apparatus 10 is provided with a removable magazine 110 for automatically feeding the topmost of a stack of documents in to the machine, the machine being such that, on removal of the magazine, documents to be copied can be fed in manually. Documents are fed in one at a time through a slot 26 and are conveyed by rollers 28 past a switch 86 which is actuated by the leading end of a document. This causes copy paper to be fed from a roll 88 until the trailing end of the document clears the switch 86, when the roll is stopped and blades 100, 102 sever the web, which is then charged by a unit 50. The document is illuminated by a lamp 62 and an image is reflected by a mirror 66 on to the simultaneously moving copy paper which is traversed past an aperture 58. The document passes to an outlet slot 44 and the exposed copy sheet to a toner tank 70, thence via a drying unit to a storage tray 78. The magazine 110 carries rollers 164 for feeding the topmost original into the slot 26. When the leading end trips the switch 86 the rollers 164 are stopped, but the original continues to be fed by the rollers of the machine. When the trailing end clears the switch 86 the rollers 164 are restarted to feed the next document into the machine.

Abstract: 1,227,848. Pneumatic apparatus. K. FRIEBE. April 22, 1968 [April 28, 1967], No. 18961/68. Heading F1P. [Also in Division F2] The connections between the components of a pneumatic circuit are made through a device which comprises a plurality of inlet conduits 2, a plurality of outlet conduits 3 crossing the inlet conduits, a transfer connection between each inlet and outlet conduit, and a manually operable valve 7 in each transfer connection. Thus when an inlet conduit 2 becomes pressurized by fluid or electric operation of its inlet valve 4, those outlet conduits in communication with that particular inlet conduit through an open transfer valve, become pressurized. This pressurization of particular outlet conduits may cause direct operation of e.g. actuators connected thereto or of relay valves 5 indirectly controlling the actuators. Alternatively flow through a transfer conduit may be arranged to cross its outlet conduit and be vented to atmosphere. This venting is used to destroy a low-pressure signal which exists in the outlet conduit whereby a relay valve responsive to the signal is caused to change its position. An exemplary circuit comprising a pair of actuators operable in sequence is described, Fig.5 (not shown).

Abstract: 1,227,930. Electro-photographic apparatus. LITTON BUSINESS SYSTEMS Inc. Feb.20, 1968 [Feb.20, 1967], No.49831/70. Divided out of 1,227,201. Heading G2H. A document copying machine comprises means for transporting a document 11 to be copied through the machine, a first light source 6 for forming an image of the document on a copy sheet, means for developing the said image and, prior to the first source a second light source 19 arranged so that when the document comprises photo-chromic material with data having the same colour as the material in its excited form, the second source excites the material and hinders or prevents copying of the data. In electro-photographic copying apparatus paper 11 carrying data passes between rollers 12, 13 under a flashing light source 19 e.g. a gas filled tetrode, and a projector 6 which produces an image of the paper 11 on copy paper 2 coated with a photo-conductive composition charged by device 4. The image is developed by passing the paper 2 through a cascade of fusible resin particles and tiny glass carrier heads and over a heating drum 17. If the paper is photo-chromic it is excited by the source 19 rendering the data indistinguishable and preventing reproduction. After passing through the machine the paper is kept in the dark and thereby reverts to its original form. A sheet of this photo-chromic material forms the subject matter of Specification 1,227, 201.

The laser beam projector assembly 42 shown in Fig. 3 may be tripod mounted and levelled so as to provide the desired horizontal reference or in an alternative arrangement the unit 10 is mounted vertically and a system of reflectors and prisms are provided at the ends of the tube 46 to project opposed horizontal laser beams along axes which are parallel and displaced vertically relative to one another. The reflector shown in Fig. 17 is adapted to be mounted at the top of a storey pole which is preferably telescopic and associated with a tape which enables the height of the reflector above the base of the storey pole to be measured. The reflector comprises a triangular prism 250 mounted with its base substantially perpendicular to the intended direction of the laser beam so as to reflect the beam back along its own path. Such a prism allows for errors in orientation of the base of the prism relative to the laser beam. In an alternative arrangement a matrix of closely spaced small prisms may be provided in place of the single prism 250. A level 262 is provided to shield the prism from the daylight. Intermediate targets such as that shown in Fig.14 may also be provided these having a central hole 242 for passage of the laser beam and a prism matrix 244 surrounding it to reflect a red light back to the laser unit when the device is misaligned. In some cases the main targets may be of this form with a central aperture and a mirror therebehind at 45 degrees to the beam to allow the beam to be deflected and viewed from beneath the target. In place of the mirror a light guide or a translucent screen with marked indicia may be employed or the laser beam may be detected photo-electrically for indication at a remote station. In a further arrangement a trapezoidal prism may be employed to direct the laser beam through a known desired angle in a horizontal plane in order to avoid an obstruction.
