Title: Improved spring mounting means
IPC: B60G11/42
Filed: 1961-06-28
Abstract: 951,073. Springs. FORD MOTOR CO. Ltd. June 28, 1961 [June 30, 1960], No. 23367/61. Heading F2S. A resilient mounting for the ends of a leaf type suspension spring 10 comprises a cupshaped piece of natural or synthetic rubber 32 which is placed under compression, but not bonded to, two correspondingly-shaped nested brackets 24, 28.

Title: Improvements in brakes
IPC: B60T8/18
Filed: 1929-05-14
Abstract: 322,237. McDermid, W. F., Glascodine, R. T., and Spencer, A. May 14, 1929. 1929. Hand and foot actuation; force-transmitting mechanism; railway and like continuous chain, rope, and rod.-Hand and foot actuated brakes, for motor lorries with provision for actuating trailer brakes, are constructed so that the braking effort is transmitted through a cam lever which increases its leverage when the slack in the rigging has been taken up, the brakes of the trailer and lorry being applied through a floating lever which proportions the braking effort to the load. A system is described wherein a pedal and handlever apply two sets of brakes on the lorry and movement of either applies also the trailer brakes when a trailer is in use. A pull rod 3 from a hand-lever has a forked end embracing a lever 5 having an arc shaped or cam surface engaged by a roller 4. The lever 5 is on a shaft 6 which also carries a lever 7 connected to an intermediate point of a forked lever 9, Fig. 5, the lower end of which is connected to a rod 11 of the lorry brake transmission. The upper end of the lever has an extension 10 entering a slot in a plate 14 connected to a rod 15, Fig. 2. When there is no trailer in use the rear end of the rod 15 is connected to a spring eye 28 but when a trailer is coupled to the lorry the rod 15 is connected to one end of a Bowden transmission passed through a hole 30 in the frame adjacent to the eye 28. A pull rod 19 from a pedal has a roller working in a cam slot in a second lever 17 which acts on a brake transmission rod 23 through a lever precisely similar to the lever 9. The upper end 22 of this lever also passes through a slot in the plate 14 so that the trailer brake can be applied either by the hand-lever or the pedal. The cam surfaces may be formed on the hand-lever and pedal instead of on levers in the transmission. A spring stop may be arranged in conjunction with the rod 15 to ensure efficient application of the lorry brakes should the trailer brakes fail.

Title: Continuous cinematographic contact printing apparatus
IPC: G03B27/08
Filed: 1951-10-09
Abstract: 712,533. Photographic contact-printing apparatus. DEBRIE, A. V. L. C. Oct. 9, 1951 [Dec. 27, 1950], No. 23505/51. Class 98(2) [Also in Group XL(b)] In the contact printer the rectangular crosssection of the light beam incident on the printing and light sensitive films, which are in contact and moved continuously, is varied by a mask-band having several rectangular transparent portions of different areas and moved across the light path between the films and an optical condenser, means are provided to ensure that during the printing of each scene said cross-section of the beam remains constant, and a fixed semi-cylindrical lens is mounted in the light path from the mask-band with its geometrical axis parallel to the longer sides of the transparent portions of the mask-band and focuses the light beam upon the printing film in the form of a narrow strip of which the length is substantially equal to the width of the printing film and of which the width remains constant during the printing of a scene. As shown in Fig. 1, light from a source 1 passes through a condenser 2 on to a mask-band 3 and through a semi-cylindrical lens 7 on to continuously moved printing and light-sensitive films 9 and 11. The mask-band 3 comprises transparent portions 4 of different widths and, during the printing of a scene, remains stationary with the appropriate portion 4 in the light path so that the light beam is focused on the film 9 in the form of a narrow strip 8. When a change in printing light intensity is required, the band 3 is displaced rapidly by a Maltese Cross mechanism (not shown) actuated under the control of a notch 13 in the film 9 or in an auxiliary band moving in synchronism with the film 9. The transparent portions in the mask-band may be disposed side by side in which case, when there is a change of scene, the mask-band moves in the same sense as the films 9, 11 through a distance equal to the separation of the longer axis of the transparent portions. In a further form, the mask-band is moved in synchronism with the film 9 and carries notches which, when they pass in front of a movable member (not shown) impart by known means a rapid extra displacement to the band. Instead of notches, marks on the film 9 or the mask-band may be used to control a light-beam falling on a photo-electric cell to control the rapid advances between two scenes calling for a change in the width of the lighttransmitting area of the band.

Abstract: 1375336 Digital weighing SHINKO DENSHI KK 17 May 1973 [20 May 1972] 23515/73 Heading G4H In a weighing apparatus with digital readout, the sensitivity is automatically reduced by a factor n when the input exceeds the maximum capacity of the indicator and increased by the same factor when the input is less than 1/n of the indicator capacity. As described with n = 10, weight 1 produces a weight proportional voltage from differential transformer 2 and this is fed via rectifier 3, amplifier 4, 10 : 1 potential divider 8, 9 and switch 12 to the three digit display which has a full scale reading of 999 corresponding to 9À99g. For weights of less than 9À99 g. the switches of relay 10 are as shown and contact 13a of switch 13 actuates the left hand decimal point. If the weight exceeds 10g. an overscale signal is generated closing switch 14 to actuate the relay. This connects contacts 11 and 11a holding the relay on, reduces the input voltage to one tenth of its previous value via contact 12b of switch 12 and switches on the right hand decimal point. When the weight is reduced to 9À99g. or less, the input to the display will be 0À099 volts or less display reading 09À9 and the zero in the first place causes switch 15 to open switching the relay off and restoring the original condition. The system may also comprise a 1999 or 9999 readout, and use 3 decimal points. The weight to voltage conversion device may be a load cell comprising a strain gauge.

Abstract: 1,201,513. Opening containers. CONTINENTAL CAN CO. Inc. 17 May, 1968 [16 June, 1967], No. 23668/68. Heading B8D. A container component, particularly a container end, has a score line 18 defining a removable panel portion 19, and an anti-fracture score 22 formed within the panel and adjacent to the score line 18. The score line 18 is formed by a punching or pressing operation which results in the formation of weakened zones at the bottom corners of the score as illustrated by stress lines 23. The anti-fracture score 22 is said to reduce the stress and consequently the tendency to accidental rupture at said corners.

The resistance material may consist of various mixtures of silicon, natural or artificial graphite, clay, boric acid, feldspar, coke, soot, kaolin, silicon carbide, silicates, borates, and substances that carbonize at a high temperature. The materials are powdered and made into a plastic mass with water, isinglass, tar, petrol or other mineral or organic oils. The conductivity of the mass may be increased by the addition of powdered copper bronze or other metal or reducible metal oxide. The plastic covering material may consist of porcelain, stoneware, or clay which may be covered with a non-porous layer of glaze or enamel. Fig. 1 shows a rod-shaped heating element before firing. The ends of the ceramic sheath 1 are closed as shown at 3 in order to protect the resistance material 2 against the oxidizing action of the fire. After firing the ends 3 are ground off. The ends of the sheath are enlarged and filled with a conducting material 5 of less -specific resistance than the material 2 in order to reduce the temperature at the ends. Instead of being in the, form of a rod the heater may be shaped as a ring, disc &c.
