Abstract: 1,270,095. Articulated tractor-trailer vehicles. COUNTY COMMERCIAL CARS Ltd. 18 July, 1969 [22 July, 1968], No. 34904/68. Heading B7H. A tractor vehicle for use with any one of a variety of trailers comprises a main part 10 having at least two wheels 13, a swinging part 20 connected to the rear of the main part 10 by pivot means having an upright axis, a coupling part 22 which is connected to the swinging part 20 by pivot means having a horizontal axis and provides for attachment of the trailer, and an engine 11 drivably connected through a torque converter or change speed gear-box 12 to differential gearing 25 the two outputs of which drive respectively a first transmission driving the wheels 13 and a second transmission adapted to transmit a drive to the wheels of the trailer. The second transmission either includes a coupling 32 for driving the trailer wheels through a mechanical transmission 7, 8, 9 or may comprise an hydraulic pump for supplying hydraulic motors driving the trailer wheels. An output shaft 23 from the gear-box 12 drives the planet carrier 24 of the differential 25. One sun gear 27 of the differential drives the coupling 32 through a universal joint 30 aligned with the pivot axis of the swinging part 20. A clutch 38 for locking the differential 25 may be controlled manually and may be disengaged automatically when the swinging part 20 turns through a predetermined angle relative to the main part 10. The other sun gear 28 of the differential 25 drives the tractor wheels 13 through a hollow shaft 33, gear-wheels 34, 35, and a lockable differential 50 having two output shafts (Fig. 4, not shown) each of which has associated therewith a multidisc brake and drives a half shaft through an epicyclic reduction gear. A power take-off coupling 47 is connected through a universal joint 45 to a gear-wheel 44 selectively driven at a speed proportional to that of the wheels 13 from the first transmission or at a speed proportional to that of the engine 11 through a train of gear-wheels (Fig. 3, not shown), a shaft 40, and a coupling 41 which connects the shaft 40 to the drive to a second power take-off 39. Front castor wheels 14 on the tractor 10 are retractible by means of an hydraulic ram 15. The coupling part 22 includes a plate 55 having a tapered rear edge which facilitates engagement of the plate with a socket member 57 provided at the front of each trailer. The socket member 57 has an inverted U-shaped cross-section with tapered slots 58 for receiving the edges of the plate 55. Screws 61 are inserted into registering holes in the plate 55 and socket member 57 to secure the trailer to the tractor.

Abstract: 923,994. Cassettes. C. I. WALTER. Sept. 29, 1961, No. 35287/61. Class 98 (1). A light-proof cassette for X-ray films has means for the admission of processing fluid, so that the film can be processed without being removed from the cassette. As shown, the cassette is formed of two parts 1 and 2 of moulded plastic, fitting together along two flanged sides 3, 3a. Along the other two sides, the top part 1 has a rib 11 entering into a groove 20 formed between two ribs 17 and 18 on the bottom part 2 at one side, and a similar arrangement of ribs 12, 13, 15 at the other side. After the parts are assembled, the ribs form a lightlock, at the same time being sufficiently spaced apart to allow liquid to pass between them. The film sheet 6 is held centrally spaced from the internal walls of the cassette by projections 9, 10. The two parts of the cassette may be heat-sealed together, in which case it can be used only once, or made so as to open and be reloadable.

Filed: 1962-11-18
Abstract: 1,067,171. Boots &c. BRITISH UNITED SHOE MACHINERY CO Ltd. Nov. 8, 1963 [Nov. 18, 1962; Oct. 23, 1963], Nos. 35575/62 and 41918/63. Heading A3B. The components of an upper i.e. outer material 16, stiffeners 13, 18, 19 and lining 20 are bonded together under pressure using an adhesive which is activated by a high frequency electric field. In a first embodiment Fig. 1 the components are assembled on a lower platen 10 using spring loaded pins 13 to position the components and the adhesive is activated by a high frequency electric field. The platens 10, 11 constitute the H.F. electrodes. In a second embodiment (Fig. 5 not shown) the components are assembled on a jig (not shown) similar to the lower platen 10 and are temporarily secured together by spots of pressure sensitive adhesive or by spot welding. The adhesive is activated by micro-wave heating using electro-magnetic oscillations having a frequency of 3,000 to 30,000 m.c.p.s. which are fed along a waveguide (21) into a rectangular metal box (22), so proportioned that a standing wave is produced within it, along its length. The components pass through the box on an endless band of glass fibre fabric impregnated with polytetrafluorethylene, the longitudinal axis of the band being at an angle of 30 degrees to 45 degrees to the axis of the box. The components are pressed together by rollers (26). Suitable adhesives are adhesives having a high dielectric loss such as plasticized polyvinyl acetate, acrylic esters, polyurethanes, polyvinylidene chloride or polychloroprene. Surface decoration such as stitch-marking, design embossing or perforating of the layer of outer material may be effected during the bonding.

Title: Improvements relating to the measurement of the optical density of photographic films
IPC: G01N21/86
Filed: 1936-12-29
Abstract: 487,945. Electric control systems. SMITH, R. A. (Langer, N.) Dec. 29, 1936, No. 35619. [Class 40 (i)] [Also in Groups XXXVI and XX] In photographic printing, reversing, or enlarging, the optical density of an exposed and developed film is measured by establishing an alternating electromagnetic field to which the film is exposed, thereby causing variations in an electric circuit associated with the field, from which variations the translucency of the film can be determined, the values so obtained being used to control the printing, reversing, or enlarging process. The measurement may be made while the film is running through a treating tank, and the field is generated by a coil which is located adjacent the film and is connected to a highfrequency source. The current induced in a second coil, arranged on the other side of the film and connected to a high-frequency ammeter, valve-voltmeter or thermo-couple, is varied according to the distribution of metallic particles on the exposed film and the corresponding variations in the reading of the meter indicate the translucency of the film. In the modification shown, the film passes close to a coil 30 connected in the valve oscillating circuit I ; the circuit II is coupled to the circuit I and contains a measuring instrument 32, the readings of which vary according to the density of the metallic particles present on the part of the film adjacent the coil 30. The variations in the reading of the measuring instrument may be employed to change automatically the effectiveness of a light for printing the film &c. The translucency of a single image may be similarly measured and compared with an image of known density.

Filed: 1920-12-29
Abstract: 168,844. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Erickson, J.). Sept. 7, 1920, [Convention date]. Addition to 156,076, [Class 40 (iii), Telegraphs, Electric]. Relays.-Relates to relay or contact-making devices of the type in which the initial actuation creates two distinct movements, one movement controlling the period of time during which the other movement performs its useful function. A slow-action relay A carries two sets of contacts, one pair 4, 5 being closed when the armature 3 is attracted. The other pairs of contacts 7, 8 are set so as to be normally separated in both positions of the armature, but one contact 8 carries an extension 9 on which is mounted an adjustable weight 10. When the contact P is momentarily closed, the armature 3 is attracted to energize a relay B, whilst simultaneously the movement of the armature 3 sets the weighted arm 8 into vibration. The intermittent contact of the parts 7, 8 suffices to maintain the armature closed, and the relay B energized so long as this vibration persists. This period of vibration can be controlled as desired by adjusting the stroke of the armature 3, and the position of the weight 10.
