Title: Improvements in facsimile receivers or transceivers
IPC: H04N1/06
Filed: 1966-09-26
Abstract: 1,139,700. Copying telegraphy. MAGNAVOX CO. 26 Sept., 1966 [8 Oct., 1965], No. 42908/66. Heading H4F. A facsimile receiver or transceiver comprises a flexible member for holding a document or copy paper cylindrically curved against the inner surface of an arcuate platen, a motor driven roller projecting through the platen and co-operating with a pinch roller to advance the flexible member and document or copy paper in the axial direction relative to the platen, and at least one transducer rotatably mounted to scan the document or copy paper along a raster of lines. In the transceiver of Fig. 1 a document or copy paper is held in a flexible carrier against semi-cylindrical platen 14. For transmission, the document is scanned transversely by means of a lamp, part-paraboloid reflectors 82, 84, two diametrically-opposed lens systems 80 and photo-cell 78, all mounted in a framework 26, 76 rotated by motor 16. Longitudinal scanning is provided by drive rollers 102, 110. The light reflected from the document and received by lens systems 80 is chopped by a shutter 85 and the resulting A.C. photo-cell output frequency-modulates a carrier-wave for transmission over a telephone line to a second (similar) transceiver. The transmitted signal is demodulated at the second transceiver and causes the stylus of one of a pair of printing transducers 24 mounted on the framework 26, 76 to print through a carbon paper on to a copy paper in the flexible carrier, scanning being provided by rotation of the framework and movement of the flexible carrier as for transmission. The printing transducer (Fig. 7) comprises an armature 90 with a printedcircuit coil 180, moving in the field of magnets 88 and actuating a stylus 93. Roller 94, on a pivoted arm 202, rides against a sheet of plastic material used to hold the flexible carrier against the platen surface. Pin 212 is a loose fit in aperture 216 in the armature 90 and moves with roller 94 to position stylus 93 a predetermined distance from the platen, while the loose fit permits the stylus to exert printing pressure in accordance with a signal applied to coil 180. Details of a scanning-drive system permitting synchronization between the facsimile transmitter and the receiver, and of a mechanism enabling the scanning assembly to be moved away from the platen 14 for insertion and removal of the original or the copy paper, are given.

Abstract: 938,225. Automatic control systems. THOMPSON RAMO WOOLDRIDGE Inc. Dec. 18, 1959, No. 43168/59. Class 38 (4). In a system in which a computer performs a sequence of operations on electrical signals indicative of operation of a process and regulates a controller of at least one supply to the process to give an optimum mode of operation, the controller automatically establishes a predetermined level of operation of the process if the computer output falls to zero. In Fig. 1 transducers 2 associated with a manufacturing process unit 1 transmit electric signals corresponding to the magnitudes of variables of the process such as temperature, chemical composition &c. to separate controllers 7, 8, 9 in which they are compared with reference signals respectively derived from summators 4, 5, 6 so that any differences are effective to adjustsoldenoid-operated valves 10, 11, 12 controlling the supply of raw materials, water, electricity &c. to the process. Each summator produces a reference signal by adding a manually set signal to a signal from an electric computer 3 which is fed with signals from transducers 2 as well as stored or external signals. The computer ensures optimum production, e.g. cheapest products. The arrangement ensures reasonable operation of the system under manual control should the computer fail or be shut down. Arrangements are also described in which electric signals are converted to pneumatic signals.

Abstract: 939,950. Induction motors. MMG MECHANIKAI MEROMUSZERCK GYARA. Dec. 6, 1961, No. 43706/61. Class 35. In an asynchronous motor the stator flux circuit has a magnetic shunt in which a variable flux can be produced by varying the current in a coil surrounding the shunt. In Fig. 1 a single phase shaded pole squirrel cage motor has a rotor F and a laminated iron stator body A. The stator body has three columns a, b, c which each carry coils. Column a has a coil 1 fed with alternating current, columns b, c are magnetic shunt members with coils 2, 3 connected in series opposition and fed from a D.C. source. When coils 2, 3 are energized they divert alternating flux from columns b, c to the air gap thus controlling the speed of the motor. In Fig. 2 not shown a single rotor is simultaneously acted upon by two shaded pole stator systems so that it is possible to reverse the direction of rotation. Fig. 3 shows a two phase machine, the second phase being produced by the phase shift of capacitor K. Fig. 4 (not shown) illustrates a two phase machine with two single phase stator systems on a common core, the second phase stator system remaining as shown in Fig. 3.

Abstract: 1359498 Making boxes RENGO KK 22 Sept 1971 [28 Dec 1970] 44274/71 Heading B5D [Also in Division B8] A carton having four sides folded up from a central base portion and having sides of double thickness enclosing extensions on adjacent sides is erected in apparatus by means of belts which fold over two opposite sides and by a plunger mechanism which erects the four sides and turns inwardly the double thickness of one pair of walls. The blanks 32 are stacked against plates 34, 40, Fig. 2, and fed by a roll 35, driven from a motor 52 to rubber covered feed rolls 36, 37 adjustable by a handle 88. Each blank then passes between guides 142, 143 where a belt 125 passing round a pulley 117 moves it forward so that its base is gripped by belts 133, 135. Two further belts 163 engaging each lateral edge of each blank and a tapering guide member 203, Fig. 17, fold over portions 391 which adhere to adhesive stripes 407 applied from nozzles 214 when each blank trips a switch adjacent the entrance to the nip of belts 133, 135. On leaving belts 133, 135 each blank passes to belts 279 which carry it beneath a plunger 324 and as the blank trips a member 318 a solenoid operated valve causes cylinders 340 to be actuated and plates 342 to advance to a position beneath, but spaced from, the box base. A solenoid operated valve controlling the plunger 324 is then actuated and as the plunger descends members 289, 291 and 292 fold up the box sides. At the end of the downward stroke of the plunger a member 329 carried thereby trips a switch and the plunger rises, the box being supported on the plates 342. Upon actuation of a further valve, cylinders 307 and brought into operation and arms 297, 298 and connecting piece 300 move a bending piece 303 which folds over the inner thickness of walls 392. Subsequently the box falls on to a conveyer belt 353 and is carried beneath rolls (369, 380, Fig. 24) which square up the top edges 394. The lateral spacing of the various belts and guide members for the blanks can be adjusted by screwed rods having left and right hand threads so as to accommodate blanks of different size. Different parts of the apparatus are driven by separate motors through reduction gears and by adjustment of speeds it can be arranged that the next blank reaches the belts 279 when the previous erected box falls on to conveyer 353. An electric circuit (Fig. 35) controls the machine and includes a time switch which stops the machine if a box is not erected in a given time due to jamming of the blanks.

[Also in Division B5] A machine in which a web of plastics material is transversely stretched between endless clip chains, diverging over at least a part of their. length is provided with means for reversing each clip chain at the entry and exit ends of the machine, the means producing a lateral displacement between the feed and return parts of each clip chain, the displacement being greater than half the difference between maximum and minimum unstretched width and between maximum and minimum stretched width; each clip chain being returned outside a machine housing, and those parts of each clip track used for feed and return being displaceable in the form of a parallelogram in the individual section of each chain track. The return section of each chain track may pass through a closed duct in which cooling air flows. In one embodiment, (Fig. 1), a web fed in at E is gripped on each side by clips mounted on endless chains moving in tracks 2 and 3, and is removed at exit A over roller 11. Feed sections 2 of the tracks and return sections 3 of the tracks extend respectively inside and outside heated machine housing 1. Transverse adjustment shafts 6, which are mounted in the ribs of a machine frame (not shown) are provided with screw threads at both ends to accommodate shaft nuts. The shaft nuts are connected to slide blocks 7, 8 which support the chain track supports by way of swivel joints 18. Since the threads at the ends of the adjustment shafts are of opposite hand, rotation of handwheels 9 causes opposite pairs of slide blocks 7, 8 on each shaft to move towards or away from each other, thus altering the configuration of the chain path. Similarly the chain-reversing sprocket wheels 4, 5 at the entry and exit sections respectively, are displaced laterally by rotation of the appropriate adjustment shafts. The diameter of sprocket wheels 4 and 5 must be greater than the distance the chain tracks are displaced from minimum to maximum entry or exit widths.
