Title: An improved coupling device for mounting an instrument on a vehicle wheel
IPC: G01B11/275
Filed: 1965-02-25
Abstract: 1,096,442. Aligning vehicle wheels. B. BENDER. Feb. 25, 1965, No.8204/65. Heading G1X. A device for measuring the toe-in or camber of a vehicle wheel comprises a cylindrical coupling device having a pair of end faces 34, 36 which deviate from parallel e.g. by 0À5‹ in one radial direction i.e. along the lines 40, 42 and are parallel to each other in another radial direction i.e. along the lines 44, 46 the coupling device having a graduated scale 80 affixed thereto so that it may be set at different angular relationships to a vehicle wheel. The coupling device incorporates permanent magnets to enable it to be attached to the wheel, and if the required toein angle is to be e.g. 0À5‹ then the coupling member is set with the radial directions 40, 42 horizontal. For an angle of 0‹ the directions 44, 46 are set horizontal and the scale 80 may be used to set intermediate values. If the end face 34 is attached to the wheel then a disc (not shown) carrying an optical device e. g. a prism 28 is applied to the end face 36. A reference line 60 is viewed through the prism and with the wheel set correctly the line 60 will appear continuous in the prism. Either of the faces 34, 36 may be applied to the wheel, each kind having a different size aperture to receive the vehicle retaining nut. For measuring camber the coupling device is set with the appropriate radial direction vertical instead of horizontal.

Title: Film transport mechanism for photographic cameras
IPC: G03B17/42
Filed: 1948-03-22
Abstract: 653,654. Photographic cameras. GENERAL ANILINE & FILM CORPORATION. March 22, 1948, No. 8451. Convention date, June 11, 1947. [Class 98 (i)] In a photographic roll-film camera, the film is advanced each time a roller-blind shutter is set by means carried by one blind of the shutter and projecting through slots in the film gate to engage the film perforations aligned with said slots and means are provided for disengaging the film-engaging means after the shutter has been set and for maintaining such disengagement until the end of the shutter exposure movement. As shown, the film gate comprises wall members 10, 11, Fig. 2, supporting the usual apertured plate (not shown), and members 14, 15 for guiding the film F through the gate. The rollerblind shutter comprises blinds 16, 17, each wound at one end on a spring roller 18 or 19, Fig. 3, and pivoted to a hinge-pin 21, which passes through a reinforcing strip 22 clinched about the edge of the blind 17, are pawls 20, which, during the shutter-setting operation, are urged by the tension in blind 17 through slots in the apertured plate of the film gate into engagement with the film perforations so that the film is advanced. During such movement, the pawls contact the bevelled end 28, Fig. 4, of spring-urged baffles 25, one of which is secured to each wall-member 10, 11 and passes through a slot therein, so that these baffles are moved out of the path of the pawls. When the pawls have passed the baffles, the latter return to their normal position and on release of the shutter-setting knob there is a slight return movement of the blind 17 whereupon the pawls are moved out of engagement with the film perforations and such disengagement is maintained by the baffles during movement of the blinds to effect an exposure. In a modification, one shutter blind 31, Fig. 11, has a reinforcing strip 33 clamped about the edge of the exposure aperture therein and supporting rigidly a pin 34 carrying pawls 35, each of which has a cam lobe 36. Co-operating with each cam lobe in the same way as the baffles co-operate with the pawls 20, is a reinforcing strip 37 on the shutter blind 30. U.S.A. Specifications 1,980,546, 2,070,122, 2,136,148 and 2,320,441 are referred to.
Patent GB-964311-A (GB)
Title: Braking device for roller conveyors
IPC: B65G13/00
Filed: 1963-03-04
Abstract: 964,311. Roller conveyers. ELECTROLUX A.B. March 4, 1963 [March 8, 1962], No. 8468/63. Heading B8A. A braking roller 13 for a rollerway conveyer comprises a braking member 30 of which a leather covered conical surface 31 is engageable with a surface 27 of a light metal braking member 23. The braking member 30 is actuated by a pin 34 secured in a flange 35 which is slidably supported by a bushing 36 on a fixed shaft 19. The member 30 is also actuated by an abutment 51 which is provided on the roller and which engages grooves 49, 50 framed in the flange 35 and the braking member 30. This member may thus be rotated by the roller and at the same time be moved axially along the shaft 19. A spring 29 tends to separate the braking members 23, 30. The flange 35 is rigidly connected with a tube 38 rotatable about the shaft 19 and the tube has a spirally extending flange 39. The space enclosed by end members 43, 45 and by a tube 44 is filled with oil. When the roller is rotated by a loaded pallet 16, the tube 38 and spiral flange 39 are rotated and roller abutment 51 drives the flange 35. The braking member 30 is thus rotated and, due to the reaction of the spiral flange 39 on the oil and fixed end member 43, is moved axially to engage the metal braking member 23. When the pallet has passed or has stopped on the roller the braking members are urged apart again by the spring 29. A pallet is thus able to re-start its movement without force other than gravity.

Title: Polarographic apparatus
IPC: G01N27/48
Filed: 1971-04-01
Abstract: 1401761 Electro-chemical analysis CAMBRIDGE SCIENTIFIC INSTRUMENTS Ltd 30 June 1972 [1 April 1971] 8473/71 Heading G1N The invention relates to a pulse-energization circuit for a polarograph. The pulses may be of progressively increasing amplitude or uniform amplitude superimposed on a ramp signal. The resulting current is measured during the last part of the pulse to avoid the initial charging current. Fig. shows a "block" circuit for superimposing uniform pulses on a staircase ramp as illustrated in Fig.2 (not shown). The operation of the circuit is substantially selfevident, a clockdriven counter 12 gating fixed height pulses to adder 19 where they are superimposed on the ramp and applied to the cell 16. The pulse width is determined by a fast-clock 13 and counter 14. A further counter 22 (also driven by the fast clock) opens the "sample and hold" current-measuring-circuit at a time after the energizing pulse is applied. Alternatively Fig.4 (not shown) progressivelyincreasing-amplitude pulses may be derived by periodically gating the ramp signal on to a fixed datum signal.

Title: Improvements relating to velocity modulated electron discharge devices
Inventor: BUCKLEY GEORGE WILLIAM
IPC: H01J25/36
Filed: 1955-03-24
Abstract: 827,066. Velocity modulated tubes. METROPOLITAN-VICKEBS ELECTRICAL CO. Ltd. March 23, 1956 [March 24, 1955], No. 8619/55. Class 39(1). In a velocity modulation tube the buncher is followed by a " sorter " in which the beam and field react at one or more points so phased that the slow electrons between the bunches give up energy to the field while the high velocity electrons in the bunches are substantially unaffected, the energy acquired by the sorter from the beam being fed back to the buncher and the " sorter " being followed-by an electron lens device for removing the low velocity electrons between the bunches and then by a catcher in which energy is extracted from the finally bunched beam. The sorter may be a waveguide having internal drift tubes to prevent out of phase extraction, Fig, 2 (not shown) ; the drift tubes and guide walls can be disc loaded, Fig. 3 (not shown) and Fig. 6 or resonators coupled by waveguides or coaxial lines, Figs. 4, 5 (not shown). In a practical form, Fig. 6 the buncher comprises cavities 18, 19 excited at # and n# respectively by feedback from the " sorter " 24 and from resonator 26 excited by the bunched beam, respectively. The " sorter " is initially excited by an external signal drive, and an electron lens 25 removes the slow electrons between the bunches from the beam after they have given up energy to the " sorter ". The feedback circuits may have phase correctors 22, 23. The catcher can be a resonant cavity or travelling wave structure ; as shown in Fig. 6 it is a disc loaded annular coaxial line similar to the sorter, but the interaction gaps are progressively narrower to compensate for the slowing down of the beam. The provision of bunchers excited at f and n# respectively improves the shaping of the electron bunches. The harmonic buncher need not be operated by feedback; the feedback to the ordinary buncher reduces the amount of input signal power applied to the buncher. The feedback device from the sorter to the buncher may be a coazial line or waveguide and may if desired incorporate phase correctors.

Abstract: 652,054. Disc closures. BRITISH MECHANICAL PRODUCTIONS, Ltd. March 25, 1948, Nos. 8882 and 25698. [Class 125(iii)] [Also in Groups XXVIII and XXXVI] The plastic, polytetrafluorethylene, which, when prepared by compressing in powdered state and sintering, has the property of being able to retain under internal stress, when cold, a deformation produced when in the hot, pliable state and when reheated or subjected to mechanical shock tending to return to the original form due to the release of the internal stress, is utilized in making containers and closures therefor. Either the container or closure is made of the plastic of such size as to prevent interfitting and whilst hot is deformed to permit interfitting and allowed to cool in the deformed state. The two parts are then fitted together and the plastic part reheated when, in tending to return to its original undeformed size, it produces pressure contact with the other part and seals the container. In the form shown, a container 1 is made of the plastic by compacting the powdered substance to shape and sintering at above 327‹C. Before cooling, a lip 2 is formed around its rim. When the container is to be used, a rigid disc 3, e.g. of a synthetic resin plastic, of greater diameter than the internal diameter of the container is placed within the lip which is then heated and, in tending to return to its original shape, grips and laps over the chamfered edge 4 of the disc as shown in Fig. 2.
