Filed: 1972-03-03
Abstract: 1329405 Feeding containers into chambers SYBRON CORP 3 March 1972 [14 April 1971] 10075/72 Heading B8A Containers 18 are moved up to an inlet opening 43 of a sterilizer chamber 10 from a position on a roller conveyer 20, by pusher dogs 66 carried by a spaced pair of endless conveyer chains 56. On the container reaching and operating a limit switch 34, a stepping switch (not shown) is actuated, and allows the container to proceed if the vessel door is open. When the switch 34 is cleared, a motor 48 is started. This drives a screw 72 on which is mounted a nut 78 which carries a pushercarrying member 82. The pusher 86 is pivotally mounted on the member 82 and is biased to the position shown by a torsion spring 88 so that the container 18 can pass over it when being conveyed by the pusher dogs 66. The pusher 86 thus engages behind the container and completes its feed into the chamber. A similar mechanism may be used to withdraw the container 18 through an outlet opening at the other side of the chamber. As described (Fig. 1, not shown) there are three chambers (10), (11) and (12) served by the same roller conveyer 20. Two containers side-by-side are fed together into each chamber, by a pair of conveyer systems, each as described above. A pair of limit switches (30) respective to each system is positioned adjacent the conveyer 20. These prevent the starting of each conveyer 56 until both containers are in the correct position on the conveyer 20 ready for acceptance by the respective conveyer systems. A photo-cell control mechanism (19) may control the feed of containers 18 on to the conveyer 20 from a main conveyer 16. Stops (24) and (26) are operated in sequence to prevent oncoming containers from interfering in the piek-up of preceding containers by the feed systems.

Abstract: 615,247. Agricultural tractors. BALLU, V., BALLU, T., and CUENET, M. C. M. April 2, 1946, No. 10192. Convention date, March 4, 1942. [Classes 79 (i), 79 (iii), 79 (iv) and 79 (v)] [Also in Group XXXII] In an agricultural tractor with two driving and two steering wheels each steering wheel is independently supported by a rocking lever and one steering wheel has an alternative position for mounting at the rear part of the chassis in which rear position it is in a common vertical plane with and on the same side of the chassis as the front steering wheel. The common vertical plane may include the driving wheel on that side. Each of the steering wheels 5, 6 is mounted in a fork 14 carried on a stem 15, which is mounted in a box 16 formed in levers 7 or 8 pivotally mounted at 9 or 10 to the tractor frame 1. The gauge is varied by swinging the lever 7 or 8, which can be locked in position by bolts 13 through holes 12 on the frame 1. In a modification each stem 15 may be mounted between a pair of arms which are pivoted to the frame in the previous manner. The weight of the vehicle on each wheel 7, 8 is taken by a spring 17 between the box 16 and the stem 15 which may be helical as shown, or leaf, or torsional. Steering arms 19 are keyed to the stems 15 and are connected to half track-rods 23, 24 which are pivoted at 25 to a lever 26 which is joined to a sprocket wheel 28 mounted on a vertical shaft 27 on the frame 1. Movement of a hand wheel 29 is transmitted to the steering wheels 5, 6 through another sprocket 30 on the steering column and a chain 31 to the sprocket wheel 28. The half track-rods 23, 24 may be either telescopic tubes, or the fastening between the arms 19 and the rods may be adjustable, or different lengths of rod may be used. The arms 19 follow the vertical movement of the frame 1 by means of a flange 21 on the box 16. It may be necessary to provide alternative positions of the arms 19 for narrow gauges of the wheels 5, 6. The assembly formed by one of the steering wheels (5 for instance) and its lever 7 is detachable from the pivot 9 and the wheel transferred to 32, the lever in that case being fixed at 33 and 34. Steering in this case is as before to the wheel 6 which transmits the movement by an arm 22, a rod 35, a pivoted lever .36 to a rod 38 to the wheel 32. The seat 39 may swivel to face the direction of travel or a second seat may be provided. A motor with variable speeds in either direction is under the frame 1 on the axle 2. If a gas producer or petrol tank 40 is fitted, it is placed as shown in Fig. 1 to give an unobstructed view. An adjustable couping hook 42 is fitted. If the tractor is required for ploughing, it may be equipped to accommodate at the front and at the rear a carried plough of the throw-over or balance type.

Abstract: 687,568. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 17, 1950, [April 16, 1949], No. 10288/49. Class 39(i) In cathode ray apparatus having a magnetic focusing coil and electro-magnetic deflecting means for scanning the beam over a screen at line and frame frequencies, symmetrical current waveforms at line and frame frequencies, preferably parabolic waveforms obtained by integrating the sawtooth deflection currents, are fed to the focusing coil or an auxiliary coil, so as to reduce the defocusing of the beam that arises due to the fringe action of the deflecting field where the beam emerges from the deflecting field. The focusing coil is connected to the anodes of a pair of valves and the line and frame scanning waveforms are each integrated by a resistance-shunt condenser combination and applied to the respective control grids of the valves the amplified outputs of which are applied to the focusing coil. The Provisional Specification states in addition that the deflecting means may be electrostatic. The focusing means may also be electrostatic in which case the compensating waveform is fed to one or more of the focusing electrodes or to a subsidiary electrostatic lens.

IPC: B29D30/36
Filed: 1919-04-26
Abstract: 148,628. Sloper, T. April 26, 1919. Vulcanizing tyres.-In making pneumatic-tyre covers, a partially vulcanized flat sectioned tyre cover A, Fig. 1, is expanded by the direct action of fluid pressure and is retained in its expanded condition for vulcanizing purposes by an internal mechanically expanded ring. The tyre cover A is placed between the plates B, B<1>, and the plate B<1> is advanced towards the plate B by the ram C. Air, admitted to the chamber D' from the reservoir D<5>, expands the tyre cover so that its centre part is forced outwards to give the desired shape. During the expansion, the expansible ring F is held in its contracted form, Fig. 3, by the pin F<1> and the lever F<3>, but finally the free end F<3x> of the lever comes into contact with the plate B to release the ring. It then expands, Fig. 5, under the action of internal springs until it fills the space within the expanded tyre cover and, after the air has been allowed to escape through the cock D<6>, the plates B, B' are separated and the tyre cover is removed in its expanded form on the ring, and vulcanized. A fluidtight joint between the tyre cover and the plates B, B' is made, for beaded tyres, by means of a separate ring H<2>, Fig. 9, and a packing ring J, or, for wired-on tyres, by means of an L-sectioned packing-ring M. In a modification, a tyre cover is expanded by creating a vacuum outside it.

Filed: 1940-06-19
Abstract: 542,696. Recovering volatile liquids. BOOTH, W. E., COSWAY, R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 19, 1940, Nos. 10587, 12408 and 13957. [Class 32] In solvent extraction processes e.g. for degreasing metal articles in which the solvent is recovered by distillation from contaminated residues, an amount of water considerably less than that required for steam distillation of the solvent is added thereto and the mixture is heated indirectly to drive off a mixture of steam and solvent, the distillate is condensed, separated into aqueous and non-aqueous layers and the aqueous layer is returned to the still. When the solvent used is a chlorinated hydrocarbon e.g. trichlorethylene stabilised by a compound containing a basic nitrogen atom e.g. pyridine, triethylamine &c. a small quantity of non- volatile basic material, e.g. lime, is added to prevent de-stabilisation. A tank 1 having a sloping bottom 3 forming a solvent sump is heated by gases &c. supplied through line 2. Cooling coils 4 are provided to condense the vapours formed and the condensate is collected in an annular trough 5. The condensate flows from a receptacle 6 into a separator 7 which is provided with draw-offs 13, 14 by which the water according as it is heavier or lighter than the solvent, is returned to the still through pipe 15 and inlet 12 while the solvent is withdrawn through lines 8 or 10. The lines are provided with valves so that the vessel 1 may be used alternatively as a degreasing or solvent recovery apparatus. In modifications the separator is arranged inside the extraction tank and the trough 5 itself may be adapted to provide separation of the solvent and aqueous layers.
