Abstract: 1,234,374. Facsimile transceivers. XEROX CORP. 16 June, 1969 [17 June, 1968], No. 30398/69. Heading H4F. A self-test facility for a document facsimile transceiver, e.g. of the Telecopier type, comprises means, including an enabling switch 66, for energizing both the scan circuitry 62 and print circuitry 64 and coupling means, such as a dummy telephone headset 78 which produces audio coupling between transmit and receive transducers 82, 84 in an acoustic coupler 36, for coupling the output of the scan circuitry 62 to the input of the print circuitry 64. The scanning part of the transceiver, in this case comprising two scanning heads 24, 25 on a rotating turret scanner unit 4, scans a test label fixed to a test document 59 and the printing part, in this case impact printing heads 34, 35, simultaneously reproduces the image of the label elsewhere on the document 59 for comparison with the original. The acoustic coupling arrangement may be replaced by electrical coupling, e.g. inductive in nature. The test document 59 may use a carbon, or other colorant, paper or a system involving the use of encapsulated colouring fluid. Alternatively the impact printing arrangement may be replaced by electrolytic or electrostatic printing means.

Abstract: 1,250,773. Thermal switches. J. A. CRABTREE & CO. Ltd. 17 Nov., 1969 [23 Nov., 1968], No. 55684/68. Heading H1N. [Also in Division H2]  A polyphase protective device responsive to overload and unbalanced conditions comprises bimetallic elements 15a in each phase, slidable members 7, 8 operated by the elements, a bellcrank 6 interconnecting the slidable members 7, 8 and operating an overcentre switch device 1, 2, 4, a reset plunger 31 which may be rotated for enabling hand or automatic reset, and adjusting means for the switch and the bell-crank. The bell-crank 6 is adjusted by a screw 40 which co-operates with a projection 7a from the member 7, this projection 7a abutting an ambient temperature compensating bimetal 19 to  cause relative motion between the members 7, 8 and operation of the switch when balanced overload conditions exist. The switch has metal blades 1, 2 pivoted on a bracket 3 and maintained in an over-centre position by a C-spring 4. The position of the bracket 3 is adjusted by a screw 14 and one position of the blade 2 is determined by a screw 41. The screws 14, 40, 41 are adjusted on assembly, the overload setting by the user being effected by a manually operated lever which engages a further lever (both not shown) having a tooth entering a guide slot 26 in the bimetal 19 and a cam surface engaging the face of the bimetal. The switch has a moving contact 5 which engages a fixed contact 9, e.g. to complete the coil circuit of a motor starting contactor, or a fixed contact 10, e.g. in a signal circuit. When the plunger 31 is turned it cams the contact 10 from the manual reset position shown to a position nearer the contact 9 so that the switch resets when the bimetallic elements cool. Manual resetting is effected by depressing the plunger 31 to cause the contact 10 to move the switch back over centre, auxiliary series contacts 34 being opened by the plunger while resetting is being effected.

Abstract: 1,252,454. Position resolvers. MARCONI CO. Ltd. March 3, 1969 [April 30, 1968], No.20334/68. Heading G1N. In an electrical position resolver producing a voltage of which the phase angle represents in alternation the X and Y co-ordinates of the position of a probe, 11, on a resistive panel, 1, the resistance per unit length of each of the four sides of an edge connector 22 is a non-linear function of length, which function accords to a given empirical relation, so that the relationship between phase angle and probe position is made substantially linear. An A. C. source 7, supplies a quadrative phase splitter 8 to produce outputs sin wt and cos wt, the former being fed to a point 4 on the edge connector and the latter to a point 6. Simultaneously both outputs are fed to an electronic switch 9 actuated by an alternating current source 10 so that the points 3 and 5 are supplied alternately, in phase quadrature, with the two outputs. Thus during a given switching half cycle the points 3, 4 are at sin wt and those 5, 6 at cos wt while during the next half-cycle the points 4, 5 are at sin wt and those 3, 6 at cos wt. Consequently the phase angle of the resultant voltage picked up by the probe represents in one half cycle the X-co-ordinates of probe position and, in the next, the Y co-ordinate. The required resistance/  length characteristic to correct for non-linearities of phase angle as a function of position is achieved by choosing the connector width and/or thickness in accordance with the relation; where R x  is connector resistance per unit length at a length x along a side; R T  is the average resistance per unit length over the length of a side; and # is the phase angle between the two A. C. inputs to the connector.

Abstract: 1304076 Classifying apparatus FISONS Ltd 3 June 1971 [7 May 1970] 22216/70 Heading B2H An apparatus for classifying particulate material comprises two or more screens of different mesh apertures and means capable of creating a zone of differential pressure across the screens such that particulate material fed to the region of higher pressure created on one side of each screen is drawn onto or through the screen by the differential pressure, each of the screens being movable in its own plane through the differential pressure zone. The screens may be made of stainless steel mesh or nylon mesh. The differential pressure may be obtained by the application or reduction of pressure or both. As shown, a tubular housing 1 is traversed by two endless belt screens 2, 3, the screen 2 being of smaller mesh aperture than screen 3. The housing is connected at its top by a line 6 to an extraction fan and has a bottom outlet 12. The material to be classified is fed into the lower end of the housing by means of an air blast or, as shown, by a conveyor 11. Oversize material falls through the outlet 12. The remainder of the material is drawn by the upward air current induced by the extractor fan. Depending on its size some of the material is retained on the belt screens 2, 3 and fall away therefrom into collecting hoppers 9, 10 as the belt screens emerge from the housing 1 and the pressure dierential is released. Fines are drawn through the line 6 and may be separated from the air in a cyclone. Rapping gear may be provided to dislodge material trapped in the mesh of the screens. Instead of the collecting hoppers being outside the housing they may be inside it with their mouths positioned closely adjacent the screens to provide areas of the screens over which the differential pressure is reduced. Alternatively, each screen may be in the form of a motordriven circular screen positioned with its axis of rotation parallel to the axis of the housing 1 so that part of area is in the differential pressure zone and part outside it.

As described, coins inserted through a shoot 3 (Fig. 2) pile against an inclined face 8 of the receiver 5, the final inserted coin 18 being elevated by a step 7 of a supporting platform 2. A projection 9 serves to support any further inserted coins during operation of the mechanism. The mechanism can be employed in a vending machine having two columns of articles for sale, as described in Specification 1,322,326. The carrier 4 (Fig. 1) when moved to left or right by a manually operated handle carries with it the receiver 5, the upraised coin 18 serving to raise the appropriate latch 10 from the path of a projection 9. Coins may be refunded by a button 15 which pivots away a plate 16 and thence the receiver 5. Articles may be sold at different prices by insertion of a spacer 8 (Fig. 2). For different priced articles in the two columns, the receiver 5 has a coin capacity required for the higher priced article column. As the partially empty receiver 5 is moved towards the lower priced article column, the last inserted coin is raised by an appropriately placed pin (17) (Fig. 3, not reproduced) to cooperate with the latch 10.
