Title: Electrical method and apparatus for testing membranous articles
IPC: G01N27/92
Filed: 1975-07-25
Abstract: 1495670 Testing membranes BAXTER TRAVENOL LABORATORIES Inc 25 July 1975 [29 July 1974] 31123/75 Headings G1N and G1S The presence in a membrane of holes larger than a predetermined size is detected by bringing oneside of the membrane into contact with a membrane incompatible electrolyte fluid and the other side into contact with an electrode while imposing an electric potential between the electrolyte and the electrode and also a pressure differential which urges the electrolyte to pass through any such holes thus producing an electric current which can be used to indicate the presence of a hole. The membrane tested may be a hydrophobic porous film and the pressure differential insufficient to permit the electrolyte to pass through pores of up to, say 1 Ám, but sufficient to allow it to pass through larger holes. The size of hole detected can be determined by the pressure differential. The electrolyte is preferably an aqueous carbonic acid solution having a pH of less than 6. Apparatus may comprise a roller 16 having a sponge-like outer layer 50 containing the electrolyte 52 and a roller 14 forming the electrode which is rotated about a stationary core cut away to provide an evacuation chamber 42 which is connected to a vacuum source to provide the pressure differential. The membrane strip 10 is passed between the rollers 14, 16 and the presence of an over-sized hole 56 is indicated by current in circuit 61. This may be used to stop the rollers or operate a dye mark on the membrane. The position of the hole across the strip may be located by isolating electrodes in separate axially-spaced sections Fig. 7 (not shown). The membrane is passed to a drying roller 18 which has an evacuation chamber 64 and a heater 20. In an alternative embodiment Fig. 6 (not shown), flat plates are used in place of the rollers. The membranes tested are used, for example, in blood oxygenator devices.

Filed: 1966-07-12
Abstract: 1,185,017. Warp beaming apparatus. COURTAULDS Ltd. 11 July, 1967 [12 July, 1966], No. 31240/66. Heading DIM. In warp beaming apparatus in which the speed of the beam is reduced as winding progresses, in order to keep the yarn speed constant, the position of a member such as a comb 10 is also controlled. As shown, an induction coupling 3 between a driving motor 2 and the beam 1 is controlled by signals from a control unit 5 in accordance with voltage applied to said unit by a tacho-generator 8 coupled to the front roller of three tensioning rollers 7 for the warp sheet 6. The height of comb 10 is regulated by a reversible motor 13 through a rack and pinion drive 12, 11 under control of a unit 18 which compares the voltages derived from a tacho-generator 20 coupled to the beam and a contact 14 of a rheostat 16 to which is applied the voltage from tacho-generator 8. The contact 14 moves with the comb 10 so that as the speed of the beam reduces during winding the comb 10 is progressively raised. The control unit 5 may incorporate a safety switch to shut down the apparatus if no signal is received from the tacho-generator 8 as when no yarns are being wound. A member of the braking mechanism for stopping the beam on yarn breakage or termination of the winding, may be actuated by the rack 11 to increase the braking force in proportion to the inertia of the beam or the diameter increases. The width of the comb during the winding of a diablo beam may be increased as the diameter of the beam increases. It is stated that electrical current or frequency could be utilised instead of voltage as the controlling quantities and that a hydraulic or pneumatic system under electrical control could be used instead of motor 13 for actuating the comb 10 or other controlled member.

IPC: G03B13/20
Filed: 1971-07-05
Abstract: 1300904 Distance determining means BELL & HOWELL CO 5 July 1971 [22 Jan 1971] 31459/71 Heading G2A A gravity-operated distance determining mechanism which, as the camera is tilted to align the optical view-finder axis with the base of the subject, causes the indicator 42 to take up a position in the view-finder window indicative of the distance, has also a pointer 66 connected to the focusing ring 20, so that aligning pointer 66 and indicator 42 sets the focus accordingly. As shown, the indicator 42 forms part of a U-shaped member having beam portions 44, each beam portion passing round a pin 58 fixed to the housing wall 26 of the view-finder assembly 16. Also fixed to the housing wall is a further pair of bearings 34 on which are mounted two pendulous members 50 having slotted upper portions 52. Each beam 44 ends in a leg 60 which engages in a slotted portion 52. In determining the distance of the subject, a person of average height looks through the eye-piece 28 and tilts the camera until the viewing axis 38 is aligned with the base of the subject. As the camera tilts, the weighted beams 44 tend to remain horizontal, so that the indicator 42 apparently rises in the view-finder window. The pointer 66 is mounted in a body portion 74 which can slide on a vertical rod 76, portion 74 being urged upwards by a spring 78. A cord 68 is attached at one end to portion 74, and the cord passes round focusing ring 20, its other end being attached thereto at 70. Thus as the focusing ring is rotated, pointer 66 moves vertically. As the camera is tilted, therefore, and indicator 42 moves relative to the window, then the focus is set for the corresponding distance by rotating the lens ring until the pointer coincides with the indicator 42.

Title: Improvements relating to traffic controlling apparatus for railways and the like
IPC: B61L23/24
Filed: 1922-11-21
Abstract: 203,241. Kershaw, A. G., and Westinghouse Brake & Saxby Signal Co., Ltd. Nov. 21, 1922. Staff, tablet, and ticket systems.-Token issuing instruments have a handle displaced in different directions from the normal to permit withdrawal of a token from a distant instrument or to release a token from the instrument and are arranged so that the insertion of a token reverses the polarity of the current which can be transmitted from the instrument. The figure shows a diagram of the circuits and the essential parts of the instrument in their normal position as seen from the back. The operating handle 1 is normally vertical and may be rotated in either direction under control of electromagnetic locks 52, 53 which are pressed home by mechanical means during a small supplementary axial movement of the handle spindle after each operation. The spindle carries a toothed segment 2 coacting with a rack on the slide 3 and also linked to a crank 4a on a shaft 6 in order to rock this shaft in a constant direction whenever the handle is rotated' clockwise and counterclockwise. The shaft 6 carries a switch drum 11 and is clutched to a shaft 8 carrying a reversing commutator 15 and a pair of horns 9 on which a token 10 rests when inserted into the instrument. A pushbutton 33 in the centre of the handle 1 acts through a bell-crank 31 and a link 30 to move the switch fingers 21, 22, 23, 24 into contact with the commutator 15 and to open the contact 27. Simultaneously a finger 34 acts on a token 10, if one is on the forks 9, to rotate the commutator 15. The instrument also includes a bell 38, an indicator 55 and a polarized releasing-relay 40. Other devices not shown on Fig. 1, but included in the instrument as described, are a spring replacing means for the switch fingers and finger 34 and a magazine for the tokens enabling the storage of a large number of tokens in a set of channels, from which they are supplied, in order, through a rocking distributor on the handle spindle. To issue a tablet at station B, the operator at station A presses the push button 33 and the negative pole of the battery 36 is connected to the line-wire 56 and relay 40 at B. Magnet 51 at B releases the slide 3 and enables the operator to turn his handle 1 counterclockwise, and so reverse the. commutator 15. Depression of button 33 at B then causes energization of magnet 50 at A, enabling rotation of the handle 1 clockwise. This movement delivers a token from a cavity in the spindle to a delivery aperture on the instrument. Both instruments are left locked in their new positions until the token is inserted at either station in a receptacle from which it is passed to the forks 9. Depression of the press button 33 then rotates the commutator 15 to its normal position and causes energization of the magnet 51 at the other station, so enabling resetting of that instrument to normal and permitting the sending of a releasing current to the instrument at the distant end of the line.
