Title: Improvements in or relating to filling apparatus for example for filling bottles
IPC: B67C3/04
Filed: 1958-01-22
Abstract: 821,489. Bottling. SEITZ-WERKE G.m.b.H. Jan. 22, 1958 [Feb. 21, 1957], No. 2119/58. Class 125(2). In a high-pressure bottling &c. machine having a reservoir 11, that part 13 of the filling head which extends within the reservoir is enclosed by a sleeve 16 having valves 17, 18 for flow of gas or liquid respectively these valves being closed when a head is to be removed, emptying of the reservoir being thus avoided. As shown, valve 17 is opened by a rod 19 when the head is in position and valve 18 falls open by gravity when the pressures in the sleeve and reservoir are thus equalised. When a head is re oved, valve 17 falls shut and the pressure in the sleeve drops, the high pressure in the reservoir forcing valve 18 on to its seat. In a modification, the sleeve and head do not extend within the reservoir but the sleeve is connected thereto by gas and liquid pipes fitted with the control valves.

Filed: 1975-01-20
Abstract: 1460263 Fluid-pressure apparatus POCLAIN 20 Jan 1975 [24 Jan 1974] 2430/75 Heading F1P In the circuit shown, with valves 7, 9, 12 as shown, a pump 2, driven by a motor 1, supplies fluid to a receiver 6. Valve 7 may alternatively return fluid to a tank 4. A position pick-up 7a signals the position of valve 7 to a logic system 16 and if fluid is being returned to the tank the valve 9 is caused to move by the logic system 16 so that fluid is fed into a pipe 10. The system 16 also causes the valve 12 to move to the position shown so that fluid in pipe 10 pressurizes an accumulator 11. If the machine operated by the circuit is idle for a long enough period, the accumulator becomes fully charged and a device 17 conveys this information to the logic system 16. This causes the valve 9 to switch over and fluid is returned to the tank. If an operator moves the valve 7 to supply the receiver 6, the valve 9 moves to the position shown, if it has not already done so because the accumulator is fully charged, and the valve 12 is moved to the position in which the accumulator is connected to the pipe 5. Depending on the relative pressures in the accumulator and the pipe 5, fluid may flow through a non-return valve 14 into the pipe 5. If pressure in the pipe 5 causes a relief valve 19 to open a sensing device 15 and the logic system 16 cause the valve 12 to isolate the accumulator from the line 5.

Title: Improvements relating to transport and like vehicles
IPC: B65G63/00
Filed: 1931-01-26
Abstract: 366,707. Vehicles with removable bodies. CAREY, W. L. DE M., 52, Norfolk Square, London. Jan. 26, 1931, No. 2497. [Classes 103 (iv) and 108 (i).] In a railway freight wagon, lorry or like transport vehicle of the kind in which the goods are carried in a number of separate containers e a c h adapted to rest on a pair of floor rails r, the rails are provided with hinged end sections s that normally hang downwardly at a steep inclination but can be swung upwardly to the level of and into alignment with other rails t to or from which a container is to be transferred, while suitable stops are provided for preventing the container from lateral movement when the end sections s are in travelling position. In the construction shown, the stops are in the form of teeth u, which are mounted on arms m constituting extensions of the sections s and co-operate with racks k on the frame members a of the containers. The teeth of the racks k may be so arranged that they prevent movement of a container in either direction or they may, as shown, prevent movement in one direction only, in which case additional stops or pins r on the arms m may engage the container wheels w on the inside, such pins also serving to centralize a container when it is run on to the vehicle. Alternatively, the container may be centralized by swinging the sections s upwardly beyond the horizontal position. In order to prevent the containers from tilting sidewise during transport pins d on the members c that carry the wheels w engage under projecting ledges q of brackets p mounted on the vehicle frame members v. If the tops should at any time fail to prevent the container from running down the sections s at one side, the upper ends of the brackets z that carry the hinges h engage with the racks k and arrest the movement ; or, if desired, by allowing the containers to overhang the vehicle on each side, the brackets z and racks k may constitute the only stop means, the arms m being dispensed with. At a loading station, the sections s may come into engagement with inclined guides g that raise the sections to the desired level for loading or unloading, while additional guides f may ensure the subsequent descent of the sections.

Abstract: 1,039,422. Abrasive tools. CHRISTENSEN DIAMOND PRODUCTS CO. Jan. 21, 1965, No. 2638/65. Heading B3D. A tool for working refractories for furnace linings, brick, concrete, asphalt paving, marble, granite, slate, ceramics, plastics &c., comprises a generally cylindrical body of a matrix material adapted to be rotated about the axis of the cylinder, the body having an integral ridge of the matrix material extending around its periphery, and cutting diamond material embedded in the ridge to provide, upon rotation of the body, a continuous cutting edge over the axial extent of the helical ridge. A hub 12, Fig. 4, e.g. of steel, having an internal keyway 14 and external ribs has a generally cylindrical matrix body 16 cast on its periphery. The body 16 has a multi-start helical ridge 22 in which are embedded single relatively large pieces of cutting diamond 21, Fig. 6, so spaced along the ridge as to provide axial overlap. Alternatively, the ridge may be impregnated with small diamond grits. The end faces 27 of the matrix body lie on a helix of the same inclination as the ridge 22. Two end faces 27 each extend 180 degrees round the matrix body, lie substantially midway between adjacent turns of the ridge and terminate in inwardly extending shoulders 28 lying on a common diametral plane. A number of tools may be assembled on a driving shaft 10, Fig. 2, and secured by a key 14. Spacers 20 ensure continuity of the ridges of adjacent tools. Workpieces C, Fig. 1, are secured to a table D which moves them under the tool assembly A rotated in a frame E. Coolant supplied to the tool and workpieces passes around the helical space between the turns of the ridge to flush cuttings therealong and clean and cool the ridge and the cutting diamond material mounted therein. When single pieces are used, the tool is rotated at milling cutter speed and not at grinding wheel speed.

Title: Synthesis of pyridines
Filed: 1955-02-02
Abstract: A pyridine is manufactured by reacting a 1,1,3,5 - tetra - alkoxypentane with ammonia.  Preferably the tetra-alkoxypentane used as starting material contains lower alkoxy groups such as methoxy, ethoxy, propoxy or butoxy groups and they may be the same or different.  Desirably the reaction is carried out with excess ammonia, in the vapour phase, at elevated temperature and in the presence of a dehydrogenation catalyst, for example, alumina, chromic oxide, silica gel, thallic oxide on silica gel, thorium oxide on silica gel or mixed silicaalumina gel.  The catalyst may be used in the form of a fixed bed or in fluidized form.  In some cases improved yields are obtained by using a catalyst promoter, e.g. small amounts of hydrochloric acid when silica gel is the catalyst.  In the examples: (a) 1,1,3,5-tetra-methoxyhexane is heated and mixed with ammonia in the presence of a catalyst consisting of activated alumina coated with chromic oxide to give pyridines consisting mainly of 2-picoline with small amounts of butidines and collidines; (b) the process of (a) is repeated using 1,1,3,5,7-pentamethoxy octane as starting material to give a mixture of pyridine bases; and (c) the process of (a) is repeated using silica gel, which may be activated by hydrochloric acid, as catalyst.  The 1,1,3,5-tetra-methoxyhexane used as starting material may be prepared by condensing methyl vinyl ether and methanol in the presence of a Friedel-Crafts catalyst.

Abstract: 494,709. Photographic roll - film cameras. BRONZAVIA SOC. ANON. April 26, 1937, No. 3179/38. Convention date, April 25, 1936. Divided out of 494,524. [Class 98 (i)] A double acting locking member is provided between the shutter release member and a control member which simultaneously advances the film and tensions the shutter. The shutter of the camera comprises rotary blades 9, 10 mounted on a shaft 11 and provided with a tensioning spring 20. The tensioning device includes a rack 21 connected to a rod 22 and handle 23 and to a sprocket 24 through ratchet and pawl mechanism 25, 26 and a spindle 27- A locking pawl 28,29 holds the spindle 27 against movement. The rod 22 also has teeth 49 to drive a ratchet film feed mechanism. The mechanism for releasing the shutter comprises a pawl 33 pivoted on a pin 34 and carrying a finger 33a which, under spring action, enters a groove in a fixed abutment 33b. A bellcrank lever 37 has one end under the finger 33a and, when rotated, lifts the latter out of the groove and allows the spring 20 to drive the shutter. A braking finger acts on the shaft at the end of its rotation. A groove 39 is brought into alignment with the arm 38 of the lever 37 when the rod 22 is in its end position, and therefore only permits release of the shutter when the latter has been tensioned. To enable the rod 22 to be locked in its end position after the return stroke, a pivoted balance member 40 is provided one arm 41 of which is a leaf spring and acts as a detent for a collar 42 on the rod 22. When the rod is moved inwardly, its collar 42 engages a cam surface 43 on the member 40 and lodges the end 45 under a catch 46. During the return movement of the rod 22, its end 46 rides over the spring 41, but is then prevented from being actuated until the shutter has been released. The arm 38 of the lever 37 then releases the catch 46 and the member 40 is. swung by the spring 48 into its free position. The camera itself is divided into compartments and carries a rotary objective holder. Specification 494,524 is referred to.
