Abstract: 1381125 Automatic control of position XYNETICS Inc 26 June 1972 [28 June 1971 ] 29868/72 Heading G3N [Also in Division H2] In a servo-control system for positioning a head 11 (see Division H2) which is movable over a platen 15, Fig.1 (not shown), phase displaced output signals from a position pick-off 36 in the head are combined with position command signals to produce an error signal which is combined with the pick-off output signals to produce phase displaced signals for energizing an actuator 20a, 20b in the head. The circuit shown is for movement of the head along a single axis. As shown, the error signal is combined in multipliers 84, 85 with the demodulated outputs of the pickoff, the multiplier outputs then being fed through driver amplifiers 90, 91 to the coils of the actuator. The demodulated pick-off outputs may be stored in digital form (in digitizer 99) for future use. The circuit of Fig.5 (not shown) forms part of an x-y plotter, separate circuits similar to that of Fig.4 being included for controlling movement of the head along the two axes. The Fig.5 (not shown) circuit also includes further components, associated with the x-axis pick-off and actuator coils, for preventing rotation of the head about an axis perpendicular to the platen surface.

Abstract: 536,381. Vaporizers. NAM, C. S., FAWKES, W. H., and LLOYD, H. E. DRUMMOND-. Nov. 11, 1939, No. 29887. [Class 7 (iii)] In an engine constructed for use with petrol, the normal carburetter, which is retained for starting purposes, is supplemented by a vaporizer for heavy oil. The vaporizer is exhaustheated and comprises a casing 1 with an exhaust inlet 2, a baffle-plate 31 and separate passages 4, 5, in which the oil and air are heated respectively. The passage 4 is connected to the carburetter, not shown, in the vicinity of the choke tube and the air passage 5 is connected to the air inlet opening of the carburetter, oil from a float chamber 11 is supplied to the casing 8 of an injector 7 which discharges into the passage 4 through a helical passage 13 the dimensions of which increase towards the delivery end. By adjusting the injector axially the quantity of delivered fuel may be varied. Delivered with the fuel is a small quantity of air which is regulated by a member 9 and discharges through a central channel 9<1>. A throttle valve 4<3> is disposed in the passage 4 and means are provided to change over.the fuel supplies to the vaporizer and carburetter. The change-over may be effected by hand, or automatically by a heat-sensitive device such as a thermometer 25. Waste products may drain away through a non-return valve 27 which also acts as a pressure - relief valve. Cleaning the passage 4 may be effected by removing the cap 4<1>. The rate of flow of the exhaust gases through the vaporizer is controlled by a valve 3<1>. A blow lamp may be inserted in the elbow 32, if required.

Title: Improvements in and relating to clothes wringers
IPC: D06F45/18
Filed: 1950-12-12
Abstract: 683,009. Wringers. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 12, 1950. [Dec. 28, 1949] No. 30342/50. Class 138 (ii). A power driven clothes wringer comprises a roller supporting frame 4 pivotally mounted on a head 1 by means of a vertical pivot 27, and a driving member 17 journalled in the head and connected to one of the rolls 5, 6 by a flexible connection which not only transmits torque but wholly supports the adjacent end of the driven roll 6 and allows the axis of the latter to swing about the axis of the pivot 27 through a predetermined angle while maintaining the driving connection and support. The driving member 17 may comprise a. gear having an axial socket 18 in its hub into which a shaft 20 of the roll 6 extends. As shown in Fig. 4, the socket 18 is of square section and balls 23 seated in dimples in the shaft 20 engage the walls of the socket 18 to impart drive to roll 6. The balls 23 also permit limited pivotal movement of the roll 6 in a horizontal plane, which occurs in the actuation of an "instinctive" release, when fitted. Corresponding horizontal pivotal movement of the upper roll 5 is permitted by journalling its shaft in a bearing block 15 formed with vertically extending arcuate grooves 16 which slidably receive ribs 14 extending inwardly from the sides of a pocket 12 in the head 1. The drive to the gear 17 is imparted through a drive shaft 3 coupled to a tubular shaft 32, and pinions 35, 36. The connection between shaft 32 and either of the pinions is by means of a rod 40 slidable within the shaft 32 and provided with pins 41, 42, projecting through axial slots 43 in the shaft. The pinions 35, 36 are provided with clutch jaws 35a, 36a adapted to be engaged by the pins 41, 42 on moving the rod 40 up and down respectively. This is effected by means of a yoke member 45 pivoted at one end 46 and provided with screw members 48 having pintles received in a groove in a collar 47 carried on the top of the rod 40. The other end 49 of the yoke member 45 projects through a slot 50 in an upper frame member 7 and fits within a shift knob 51 slidably carried by the member 7. A spring 52 permits the member 7 to pivot about the point 8 when an emergency type release is fitted. The arm 49 is maintained in neutral, forward or reverse positions by means of a spring detent 54 having dimples 55 which engage a hole 56 in the arm 49. In a modification (Figs. 5 and 6 not shown) the rod 40 with pins 41; 42 is replaced by an inverted T-shaped plate slidably received in a slot in a solid drive shaft which replaces the hollow shaft 32. Specification 562,164 is referred to.

Five of the vanes are arranged to define four compartments for pills and an extra compartment in which is contained the sixth vane 3b to prevent pills from entering therein. An opening 15 is formed in the bottom of the cover 1 adjacent to the vane 3b and the cap 8 is also formed with a recess 16. Pills are delivered by turning the cap so as to receive in the recess 16 a pill from a particular compartment and then bringing the two recesses 15 and 16 into alignment by further turning. The cap is formed with resilient pimples 17 and one of the vanes 3a is extended to ride over these and locate the cap in a position where the recess 16 is aligned with a compartment. When the recesses 15 and 16 are in alignment the vane 3a abuts a projecting portion 18.

Abstract: 1,029,385. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 4, 1964 [July 24, 1963], No. 30563/64. Heading H4K. Remanently latching relays in matrices of a multi-stage relay selector are energized over one set of co-ordinate wires in accordance with a mark extended from the preceding stage and a mark extended from a route determining marker (not described in detail), and are released by a reverse energization, the release of a cross-point relay in one stage connecting up the release circuit for the subsequent stage. Matrices A and B are illustrated and a marker such as MB determines which of the relays KB and which of the outgoing links CLB to CLA is to be used. A relay TB is operated during setting up to sever the forward links from earth and to disconnect a set of co-ordinate release wires in the matrix from negative potential. On energization of a cross-point relay one of its contact sets connects the relay to the co-ordinate wire of the release system and another of its contact sets further severs the forward link from earth. Since the relay is latched by remanent magnetism the marker MB can retire and release relay TB. Release of the relay is by reverse energization over the made contact of the relay and a contact of relay TB. When the relay in one stage falls back it connects the link to earth so that the relay in the next stage is reversely energized to effect release, and so on. While a marker is occupied in setting up a call over a matrix, relay TB or TA is energized and no release is possible for any cross-point in the matrix until the marker retires.
