An electrophotographic copying apparatus comprising a charging, exposing, developing and fixing devices, the developing and fixing devices being disposed in the upper part of the apparatus and beneath a substantially horizontal guide path for electrophotographic material and including a roller for applying developer, and in which a plurality of mutually spaced and parallel bladeshaped guide members which extend above the guide path from the vicinity of the roller in the direction of advance of the material, are provided, the guide members being shaped adjacent to the roller so that the lower edges of the guide members extend towards but are spaced from the roller so that the leading edge of the material is pressed down towards the roller and the developer, and in which a curved supply path is provided for deflecting the material into the guide path so that the leading edge of the material is directed towards the shaped edges of the guide members. As shown, the apparatus comprises two inlet slots 7 and 8 separated by a V-shaped guide ink which the copy material and the original are respectively fed and guided to stations 12 and 13 by rollers 14 and 15; the copy sheet being charged by electrodes 19 and 20 beneath grid 16. The original is reflex exposed at 13, the image rays passing through objective 30 and reflected by a mirror along path 32 on to the copy sheet at 12. The copy sheet is then guided through rollers 26 and curved guide plates 24 and 25 on to the longitudinal strips 51 which have curved edges 60 to press the sheet into contact with but not to cut the magnetic brush 57 on the roller 36 or with a liquid developer if this is used in which case a drying station 39 is employed which is placed below vests 53. After passing the developer, the copy sheet is fixed by infra-red radiators 39 in shield 40 before passing through rollers 42 and 43 and out through slot 45. All the rollers are driven by a common transmission and there are separate circuits for the light sources 29 and the heat sources 39 and for the electrodes 20; the transmission and the power sources being controlled by two master switches.

Filed: 1929-09-06
Abstract: 341,434. Sound-transmitting apparatus. SLEE, J. A., 16, Raphael Street, South Kensington, London. Sept. 6, 1929, No. 27177. [Classes 13 and 118 (ii).] Diaphragm vibrators ; subaqueous sound signals; determining distances acoustically. -Apparatus for emitting trains of waves, for subaqueous signalling and for measuring acoustically depths and distances, each train consisting of a small number of equal impulses, comprises means for striking a succession of hammer blows upon one or more impulsing members in contact with the propagating medium, the blows being so close together in time that their frequency and not the frequency of the impulsing members determines the frequency of the transmitted wave. The apparatus is described as applied to subaqueous signalling and in one form electromagnets B, Z, energized simultaneously attract hammers C acting seriatim on stem D attached to diaphragms E, the time at which the hammers strike the stems D being adjusted by means of screws H. The diaphragms are attached to the casing by bellows arrangements F, movement in the inward direction being limited by enlarged parts G on the stems D. The transmitter may be shut off from the external water by the closing of a sluice N. The electrical connections are brought through a pipe M, and a tube P allows the escape of air. In a modification, Fis. 3, the diaphragms E are placed in a chamber 0 communicating with a chamber X bounded by a plate Y having holes arranged to give a directional effect to the issuing sound. In further modifications, (1) one diaphragm is given a succession of blows by a number of hammer heads arranged on a spring- controlled shaft, or by a series of spring-urged concentric tubes projecting from one another ; (2) a series of spring-controlled hammers may be mechanically released to strike separate diaphragms by means of cams on a rotating shaft, the cams also resetting the hammers and releasing pawls which hold the diaphragms in their outer positions. It is stated that the hammers may operate directly on the sides of a ship. The frequency of the individual blows varies from 1000 to 30000 per second. The waves may be received by receivers of the electrodynamic or magneto-strictive types.

Title: Amplifier arrangement
IPC: H03F1/30
Filed: 1970-06-05
Abstract: 1298126 Transistor amplifying circuits PHILIPS GLOEILAMPENFABRIEKEN NV 5 June 1970 27241/70 Heading H3T In an amplifier comprising a transistor 1, Fig. 1 whose collector-emitter path is fed from a supply source U and whose base receives a biasing current through a resistor 11 from a voltage proportional to that of the supply source, the base is additionally coupled to a source 15 supplying a further biasing current which compensates, at least partly, the influence of the base-emitter voltage, so that the base biasing current is substantially proportional to the supply voltage U. A mathematical demonstration is given in the Specification that if the source 15 comprises a voltage source proportional to the base emitter voltage of the transistor, in series with a resistor of suitable value, the base bias transistor 1 remains at an optimum value as the supply voltage U changes. An embodiment comprises a transistor 1, Fig. 3, driving a series connected pair of transistors 21, 23 of opposite conductivity type, with its base biased via a resistor 11, shunted for A.C. by capacitor 25, from the commoned emitters of transistors 21, 23 which are at a potential U/2. The base of transistor 1 is also biased over resistor 15, shunted for A.C. by capacitor 39, from the collector circuit of the first stage transistor 37. The voltage U 15  at the collector of transistors 37 is made proportional to the base-emitter voltage of this transistor by biasing the base from the collector over a resistance network 43, 45, 47. A further bias is taken from the join of resistors 43, 45, over resistor 59 to bias the base of a transistor 55 forming an I.F. or R.F. stage of a radio receiver incorporating the amplifier.

Abstract: 1361907 Pneumatic controllers HONEYWEL GmbH 12 June 1972 [28 June 1971] 27329/72 Heading G3P A pneumatic controller has a balance beam 4, Fig. 1, pivotable about axis 3 in response to the action of pressure transducers 2, 5, 8 of which the latter may be adjustable along slot 9 while transducer 5 applies a feedback force via a lever 6 rotatable about the axis of transducer 5 to vary the gain and proportional band. The beam controls an amplifier 7 which is located on one side or the other of axis 3 according to whether the controller is to be direct or reverse acting. In the practical embodiment of Figs. 4 and 5, the beam 4 is pivoted to base 1 by leaf springs 18 and one or more pressure transducers 12 secured to the base engage the beam via stems 24, each transducer having adapters 35 for connection to a sensor and to an air supply restrictor (42, 43) respectively. The set point may be established by a spring 25 extending between the beam and a seat 30 adjustable upon rotation of stem 29 at 32, the actual set point being displaced by a scale ring 78 in toothed engagement with a sleeve 80 on stem 29, the sleeve being disengageable from ring 78 by depression against spring 81 to allow resetting of the ring. Feedback transducer 5 engages lever 66, 68 at 70, the lever being supported on springs 65 by a cup 64 which is rotatable by knob 75 to vary the point of engagement of the lever with the beam at 72. Extension 73 of the lever 66, 68 cooperates with scale (74) on the beam to display gain and proportional band. The amplifier 51 Fig. 4 is actuated by the beam via one of a pair of screws 53 (59) according to which side of the beam pivot axis it is located. The base 1 supports covers 93, 97 and has openings 101 for the pneumatic conduits. The pressure transducer 8 is retained in position by spring 90 which allows adjustment along slot 9. In modifications, the number, disposition and type of pressure transducer is varied according to the application, and the beam may operate as or carry a flapper and be mounted on crossspring pivots. The lever 66, 68 may alternatively be pivoted at a knife-edge and transducer 8 may be mounted on a pivoted arm instead of being adjustable along a slot. A pneumatic RC circuit may be connected to transducer 5 to provide an integral action Fig. 10, (not shown).
