Title: Web transport control mechanism
IPC: G03B21/43
Filed: 1974-07-18
Abstract: 1479303 Projector film drive EASTMAN KODAK CO 18 July 1974 [25 July 1973]  31870/74 Heading G2E [Also in Division B8] A mechanism for controlling the rotation of a spindle of a web transporting apparatus such as a motion picture projector comprises a plate which can take up one of three positions, one position in which the spindle is braked, a second position in which the spindle is driven, and a third position in which it is neither. As shown, the spindle 14 mounts a drum 42, and also carries a film reel (18) Fig. 1 (not shown). The drum has a projecting peripheral lip 44 which has inner and outer surfaces 46, 48. The control plate 56 pivots on a fixed stud 58 which engages in an arcuate slot 60 in the plate. The plate is moved between its three positions by a rod 72 whose end 72a engages in an opening 66a in a bent-over end 66 of the plate. Rod 72 is actuated by a lever 30, which can be pivoted to select different modes of operation. When lever 30 is positioned for the "still" mode of operation, plate 56 takes up the position shown in solid line in Fig. 3, and a brake pad 64 carried thereon is drawn against the inner surface 46 of the lip 44, so braking the drum 42 and hence the film spool. For the normal projection mode, lever 30 actuates rod 72 to pivot plate 56 into the position shown in phantom line, so that the brake is disengaged from drum 42, which is then free for film to unwind from the reel. When lever 30 is shifted to the left for the "rewind" mode, plate 56 is pivoted clockwise to bring an idler roller 74 at its upper end into contact with an endless belt 54, which is displaced so as to engage in frictional contact with the outer surface 48 of drum 42, Fig. 5. Since the belt is being driven in the direction of the arrows Fig. 3, by a pulley 50, drum 42 is now driven in an anti-clockwise direction for rewinding the film on the reel.

Title: Improvements in electric discharge tubes
IPC: E03D1/07
Filed: 1933-11-15
Abstract: 412,837. Discharge apparatus. MULLER AKT.-GES., C. H. F., 24, Rontgenstrasse, Hamburg, Germany. Nov. 15, 1933, No. 31872. Convention date, Dec. 2, 1932. [Class 39 (i).] In a high tension device, particularly an X-ray tube, in which two re-entrant portions, forming tubes of insulating material, each carrying an electrode, are arranged parallel with the axis of the device and extend into the device from one end, the supply conductors are led into the tubes and insulating sheaths surrounding the conductors also extend into the tubes. In one form, Fig. 1, an X-ray tube comprises a metal head 1 and a glass portion 2 con. taining re-entrant tubes 3, 4. The anode 5 and cathode 6 are mounted on these tubes. An insulating tube 13 with a metal lining 14 surrounds the cathode leads. On the anode side, an insulating tube 15 surrounds concentric metal tubes 16, 17 which deliver a cooling fluid to the anode 5. The insulating tubes 13, 15 are associated with the cable coverings 9, 10. The cables are also provided with a metal cover connected to a metal envelope 18 inside which an insulating member 19 surrounds the tube. The envelope 18 may be replaced by a metal coating on the envelope 19. The envelope 18 is provided with a spherical head 21 whose centre lies at the focal spot. A lead layer 20 is inserted between the head 1 and the insulator 19. The anode mirror is so arranged that a perpendicular to it forms equal angles with the tube axis, the axis of the cathode ray beam in the plane of the drawing and the normal to the plane of the drawing. In consequence, two beams of X-rays emerge, one axial to the device and the other normal to the first. Windows, one of which is shown at 8 are provided for these beams. The re-entrant parts may be filled with a material such as compressed air, oil or a solid cast material, resistant to breakdowns. The front of the head 1 may be shaped as a hemisphere, the centre of which lies in the focal point of the tube. The rays may emerge through a window shaped as a slit with rounded corners, giving a fan-shaped beam.

Abstract: 930,748. Automatic sorting by photo-electric means. BRITISH NYLON SPINNERS Ltd. Aug. 21, 1961 [Sept. 16, 1960], No. 31931/60. Class 40 (3). A bobbin yarn 1 is inspected by a high-definition television -camera 3 and the resulting video output fed to at least one circuit capable of detecting electrically any off standard condition or conditions that can be detected visually, the output of said circuits being used to control segregating or indicating mechanisms. The type of illumination used is determined by the conditions to be investigated, for example, dark ground illumination by light 5 may be used to illuminate any profile projecting faults 9, whilst frontal illumination by light 11, via apertured mirror 15, produces a lustre line along the axis of the bobbin and is used for the investigation of the distribution of the windings thereon. Side illumination may be used or the thread may be treated with a fluorescent substance and illuminated by ultra-violet light. The electrical circuits may be of the pulse discriminator type, the voltage comparator type or a coincidence circuit, reference signals being fed to one side thereof. A time delay circuit may be used to prevent operation of the segregating or indicating mechanisms until after a given signal from the bobbin is detected at least twice.

Title: Gear selection mechanisms
IPC: F16H61/18
Filed: 1973-07-04
Abstract: 1446337 Change-speed control CHRYSLER UNITED KINGDOM Ltd 2 July 1974 [4 July 1973] 31933/73 Heading F2D A gear selector lever movable in a neutral plane and in a plurality of planes transverse to the neutral plane to gear selection positions at either side of the neutral plane is prevented by blocking means from being moved directly from one forward gear position on one side of the neutral plane to a reverse gear position on the other side of the neutral plane, the blocking means being released by movement of the lever along the neutral plane. As shown, a rotatably and axially movable shaft 16 carries a plate 16a which, depending on the rotational position of the shaft, engages a slot 49 in a first and second speed selector shaft 46, a slot in an arm 51 fixed to a third and fourth speed selector shaft 47, or a slot 50 in a fifth speed and reverse selector shaft 48. Movements are imparted to the shaft 16 by a ball-and-socket mounted gear lever (not shown) of which the lower end 25 engages a hole in a member 24 fixed to the shaft 16. To select fifth speed the lever is moved in the neutral plane to cause a projection 41 on a member 27 surrounding the member 24 to deflect a spring- loaded abutment 29, and is thereafter operated so that the shafts 16 and 48 are moved to the right, causing the abutment 29 to prevent return movement of the member 27. A spring- loaded sliding connection between the member 27 and the shaft 16, however, allows the gear lever to be returned as far as the neutral plane, whereafter, before reverse gear can be engaged it is necessary for the gear lever to be moved across the gate to disengage the projection 41 from the abutment 29. Reverse can then be engaged by moving the gear lever to deflect the abutment 29 against its spring 36 and also against a stronger spring 39 so that the plate 16a clears an abutment (not shown) constituted by part of the arm 51, and thereafter in a direction to move the shafts 16, 48 to the left to actuate a reverse selector 64. The reverse selector has an interlock 77 with the shaft 47 and a lost-motion connection 69, 70 with the shaft 48 so that the selector 64 is operated by the shaft 48 only when the latter is moved to the left from the neutral position. In a modification, further cooperating abutments on the member 27 and in the housing prevent inadvertent engagement of an unwanted ratio during hurried movement of the gear lever from fifth to fourth speed positions.

Abstract: 1411952 Discharging hoppers K J HURST and W G PEARSON 28 Sept 1972 [8 Oct 1971 13 Sept 1972] 31945/74 Divided out of 1411951 Heading B8S [Also in Division A4] A device for dispensing predetermined numbers of discrete articles such as pills or capsules comprises a rotatable disc forming the base of a hopper, the disc having equi-spaced slots in its base into which the articles can fall, each slot comprising an inner section of a length greater than one half the maximum dimension of the article as measured along the slot, and a section outwardly of the inner section, both sections extending outwardly towards the disc periphery and being angled in the direction of disc rotation in rise; the outer section being angled to a greater degree than the inner. There may be a third peripheral section angled either towards or away from the direction of disc rotation. The disc rotates on a sloping surface and articles move towards its centre in the slots, to a discharge point monitored by a counting sensor. The hopper 27 is secured to the periphery of the disc 36 for rotation by a motor on a sloping support 24, the whole forming a unit which may be housed with others in a cabinet for dispensing several kinds of pills &c. All units may be connected to a single counting control means 18. The disc has a truncated conical upper surface 36 cut away adjacent the periphery to expose the slots to a contained mass of articles. In one form, each slot has a third section 38 joined to second and first sections 39, 41, the section 38 having a trailing angle to obviate jamming of articles entering. The leading angle of the section 39 causes articles other than that which has reached the innermost section 41 to fall back as the respective slot approaches the discharge aperture 46 on the surface 24. The sensor arm 43 is accommodated in an annular slot 44 in the disc base, which intersects the section 41 and sends a signal to a counting circuit, Figs. 7, 8 (not shown), which may be substantially as described in U.S.A. Specification 3,368,713 and includes means to stop the disc rotation when the desired count is reached. The control system may include means to permit a number of dispensing units to be operated together and to give a visual count and an indication of the number of dispensing operations, Fig. 8. In another form of disc, for pills, Fig. 6 (not shown), the leading face of the section 38 may have a depression (47) to trap the pill adjacent that being dispensed to prevent it touching the sensor arm and giving a false count. In a further form for capsules, the inner section may be curved in the direction of rotation, Fig. 16 (not shown), followed by a reversed curved portion and a straight portion leading to the disc periphery. A series of interchangeable discs to cover all pills and capsules may be supplied for a single dispenser. The disc 32a may rotate on a base 24a spring biased towards it, obviating jamming of articles between base and disc Fig. 11.

Nov. 8, 1934, No. 32087. Convention date, Nov. 8, 1933. [Class 46] [See also Groups XVIII, XXIII, and XXIX] In a system for periodically supplying controllable quantities of a liquid charged with solid particles to a number of points, for example for supplying abrasive-containing fluid to glasspolishing apparatus, the liquid is continuously circulated through pipes 1, 2 connected by flow and return pipes 5, 7 to tanks 6 containing adjustable plungers 13 for varying the capacity and provided with delivery pipes 8 both the supply and delivery pipes having obturators with elastic walls for closing them. A continuous flow of fluid occurs through each tank until it is to be discharged, when the supply pipe 5 is closed and the delivery pipe 8 opened ; deposition of the solid contents is thus avoided owing to the continuous movement of the fluid. The return pipe may provide a constant level overflow, as shown in Fig. 2, in which case no obturator is provided in it. Fig. 3 shows one form of obturator, comprising an elastic tube 17 which is compressed between a fixed abutment 24 and a plunger 18 operated by air pressure. An elastic diaphragm expanded by air pressure may take the place of the plunger 18. In a modification, the tube 17 is pressed inwardly on all sides by air admitted to a chest which surrounds it.
