Abstract: 1282448 Screw conveyers BADISCHE MASCHINENFABRIK GmbH 28 Aug 1969 [12 Sept 1968] 42943/69 Heading B8A [Also in Division B1] A screw press for dewatering tannery waste prior to transport comprises a slotted or imperforate cylindrical casing in which rotates a screw whose core widens towards the solids discharge end 47 (Fig. 8), to which is connected a conduit (not shown) several yards long down which the screw pressure forces the solids. In Fig. 2 (not shown) the core tapers uniformly, and in Fig. 8 the core comprises two sections of different diameter and a steep intermediate frusto-conical section 46. Fig. 8 shows an imperforate casing 60, a counter-pressure screw 51 and a liquid discharge opening 55. In Fig. 9 (not shown) the counter-pressure screw is uniform in section. In Fig. 2 there is no counter-pressure screw, and the casing is slotted allowing liquid to run into tank (40). The inlet at the lower end of the casing is closed by a hinged valve (Fig. 6, not shown) which opens and starts the screw drive motor (10) when sufficient waste accumulates thereon. Figs. 3 to 5 illustrate alternative constructions for the casing slots which are defined between spaced axial bars, alternate ones of which are radially adjustable. In Fig. 4 slots are defined between stainless steel rods 21 let into bars 19 and plates 22 on bars 20. Gaps between the bars resist rotation of waste being pressed and surfaces 24 may be additionally grooved to enhance this action. Surfaces defining slots may be coated with chemically resistant material.

Abstract: 1,128,082. Laminating. HOOVER BALL & BEARING CO. 27 Sept., 1966 [21 March, 1966], No. 43045/66. Heading B5N. A continuous press for treating workpieces in sheet form comprises first and second shoes having opposed surfaces in spaced apart relation, first and second sheet metal belts positioned to move over the surfaces respectively of the first and second shoes, means for moving the belts across the surfaces of the shoes with a workpiece sandwiched in between the belts, a plurality of heating elements positioned transversely of the shoes for heating workpieces moved by the belts between the shoes, and means for indicating failure of any one of the heating elements to operate. As described the press is substantially as disclosed in Specifications 1,055,564 and 1,055,566 and includes preheating and curing sections. The heating elements of one of these sections are connected in a circuit as shown in Fig. 3 and include electrical resistance heating elements 52 connected in parallel and extending the full width of the belts of the press, and zone heating elements 56 connected in parallel sets of two and controlled by switches 62, so that only those zone heating elements which lie above a workpiece 18 of narrower width than the belts are used to maintain the belts at the same temperature across the whole of their width. Conductors 68, 70 from the elements 52 pass in opposite directions through a transformer 66 and act as the primary thereof. When the elements 52 are functioning correctly there is a cancellation of flux in the transformer primary. When one element fails there is a net flux produced which induces a current in the secondary 72 which operates an alarm signal 74. The zone heating elements 56 are connected in a similar fashion to a transformer 80.

Filed: 1970-09-14
Abstract: 1320396 Electrostatic printer PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 Sept 1970 [16 Sept 1969] 43759/70 Heading G4H [Also in Division H4] In an electrostatic printer, the print electrodes 12 are arranged in groups Gr 1 -Gr n ; the record carrier 2 on which a charge is formed is arranged between the print electrodes 12 and counter electrodes G 1 -G n+1 . A given counter electrode overlaps two groups of print electrodes. The groups of print electrodes fall into two sets, Gr 1 , Gr 3  &c. and Gr 2 , Gr 4  &c., a given electrode in each print electrode group belonging to the same set being operated by an appropriate switch Z 11 -Z 2n . Thus depression of Z 11  activates the first electrode in Gr 1 , Gr 3 , Gr 5  &c. To operate the first electrode in Gr 3  a voltage must also be applied to counter electrode G 3  by closing the appropriate switch. The counter electrodes are switched in sequences of pairs, e.g. G 1  and G 2 , G 2  and G 3 , G 3  and G 4 , &c. The appropriate print electrodes are then activated when the group to which they belong is covered by a counter electrode pair. This avoids field distortion at the edge of a group of print electrodes and prevents ghost images and reduction in image intensity at the edges.

Abstract: 439,984. Ticket printing and issuing machines. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, and LUCKETT, H. W., 67, Palmerston Road, Plumstead, London. July 9, 1934, No. 20082. [Class 106 (iii)] In ticket printing and issuing machines incorporating a full-stroke mechanism, a device for registering transactions of any value in terms of unit transactions comprises a stop 1 rotatably positioned by turning the knob 13 for the purpose of setting the printing wheel 22, the units registered on a counter 7 corresponding to the extent of movement from the stop 1 of a member 4. which is moved during each ticket-issuing operation. This member 4 is spring-coupled to a disc 2 so as to follow that member until its progress is arrested by the stop 1, the disc 2 being rotated during the issuing operation, first counterclockwise and then clockwise, to the extent of seventeen-eighteenths of a revolution. As the disc 2 returns, its projection 2<a> picks up member 4 and carries it back to its unoperated position, Fig. 1. The disc 2 is oscillated by a pinion 8, meshing with a pivoted sector 18 operated by a reciprocating strap 16 spring- coupled thereto and using a pin-and-slot connection, the length of the strap 16 being such that the pivoted operating frame 23 therefore is not completely restored to its unoperated position and locking pawl 27 is not disengaged from pinion 24 until the strap 16 has been raised sufficiently not only to restore segment 18 but also to bring pin 16a to the top of slot 19a, thus ensuring that the last unit must be registered before the ticket-issuing machine can be released and reversed for the issue of a further ticket. During a ticket-issuing operation, the frame 23 is oscillated, and during its downward movement, a pinion 24 carried thereby runs down an arcuate rack 38, a pawl 26 preventing return movement of the frame until the end of the downward movement, when a bell-crank 29 engages a fixed pin 37 and is rotated so that its pin 32 is engaged by a claw 40 on a pivoted catch 33. At the same time pin 31 on the bellcrank moves away from pawl 27 so that it is spring-urged into engagement with the pinion 24, the pin 31 engaging pawl 26 and forcing it away from pinion 24 to release the frame for the upward movement. At the end of the upward movement, the catch 33 is moved by a pin 36 to disengage claw 40 from pin 32, and change over the pawls.

Abstract: 1,261,186. Utilizing holography. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec.11, 1969 [Sept. 20, 1968], No.44938/68. Heading G2J. The amplitude and/or direction of an unknown motion at at least one point on the surface of a moving object is determined by:- (a) making three holograms or pairs of holograms of the surface including the point to provide live or frozen interference fringes on reconstruction corresponding to known displacements of the point in each of three known orthogonal directions 1, 2, 3 by known amplitudes; (b) observing said point in reconstructions of said holograms from at least three viewpoints 1 v , 2 v , 3 v  in the planes of the holograms and determining the order of the live or frozen fringes produced at said point by each known displacement from each viewpoint; (c) calculating as constants the direction cosines of the measured direction of motion (defined) and the sensitivity factor (defined) for each viewpoint, said three viewpoints being chosen so that said measured directions of motion 1 s , 2 s , 3 s  are not coplanar; (d) making a further hologram or pair of holograms of the surface to provide live or frozen fringes on reconstruction corresponding to the unknown motion; (e) observing in said reconstruction the point on the surface whose unknown motion is to be determined, determining the fringe order due to the unknown motion at said point from each of the three viewpoints; and (f) using the calculated constants to calculate the amplitude and/or direction of the unknown motion. The known displacements in the three known orthogonal directions may be translational or rotational. The measured direction of motion is defined as the vector bisecting the angle subtended at the point on the surface by the source of illumination I and the given viewing point 1 v , 2 v  or 3 v . The sensitivity factor is half of this said angle. Preferably the holograms are recorded side-byside in strip form a set of four adjacent strips constituting a single viewpoint. The first three strips respectively being two superimposed holograms of each of the known displacements in the orthogonal displacements and the fourth strip being a single hologram of the vibrating object or two superimposed holograms of a distorted object. Desirably a continuous series of such groups are formed across a photographic plate subtending a large solid angle at the point of interest over the surface and thus giving a wide range of viewing points over the plate. One embodiment uses five viewing points, Fig.4 (not shown), three horizontally aligned lying in the common plane of the illuminating and viewing directions and the other two lying in a plane at right angles to the common plane of the first three.

Abstract: 1388397 Digital transmission; duplex signalling K W CATTERMOLE and G B B CHAPLIN 27 Sept 1972 [27 Sept 1971] 44940/71 Heading H4P  In a system for simultaneous transfer of digital signals in opposite directions along a channel between stations each having a transmitter and receiver, and in which the duration of received pulses are longer due to channel dispension than transmit pulses, the receiver includes means for inhibiting detection for the duration of each transmit pulse, the detector being responsive to mutiliated pulses resulting from suppression of a part. The detector may include means for performing a weighted integration of multilated pulses and testing the value at determined instants. A repeater incorporating such features may be connected into channel 3, 4 via half equalizers 9, 10 and optional hybrid transformers 5, 6. Incoming signals on line 3 are directed to the input of preamplifier 11A and passed to a sample and hold circuit 12A where influence of outgoing signals on line 3 is removed. Output signals are generated and applied to detector 13A producing two outputs, one to rectifer 15A from which is derived a series of short pulses driving resonator 16A generating sinusoidal oscillations of pulse repetition frequency which are applied to generator 17A and back to 13A to mark digit times and enable detector 13A to produce its second output as a ternary code to regenerator 18B, also controlled by 17A, thus producing a signal for transmission by hybrid transformer 6 and half equalizer 10. Incoming signals on line 4 are similarly passed to line 3 via components bearing suffix B and a timing distributor 14A acts on 12A to act on line 4 signals. A terminal station would comprise only half the components described; a part of 17A would not be required, a source of pulses being necessary. A form of sample and hold circuit is described in connection with Fig. 10 (not shown).
