Abstract: 1,001,242. Transferring load containers between vehicles. E. KANNENBERG, M. KANNENBERG, K. KANNENBERG FAHRYENGWERKE KANNENBERG, and B. AUTOMOBILWERK A.G. June 22, 1962 [June 23, 1961; Oct. 30, 1961], No. 24066/62. Headings B8E and B8H. [Also in Division B7] A container 101, Fig. 7, is transferred from a road vehicle M to a rail vehicle or loading bay over roller tracks 103 on the vehicle by braked drums 107, Fig. 12a, and cables 106, power being supplied through handles 109 or an hydraulic motor. The container runs on its own roller tracks 102 on the receiving vehicle. Retractable arms 108 on the container enable it to be moved some distance away from the road vehicle M. In a second embodiment, Fig. 15, the cable is replaced by a chain 110. The chains are coupled to extensible arms after the container has been moved off the road vehicle so that the rest of the movement may be completed. In each embodiment the roller tracks 103 may be raised by retractable jacks 105 to accommodate differences in level between the vehicles. The pivot 111, Fig. 12a, between the two parts of the vehicle is adjustable in height. In Fig. 5, a container A is transferred from a vehicle S to a loading-bar or another vehicle by a platform truck having endless tracks 1, Fig. 1, and a load platform 3 which carries track guide rollers 4, 5 and may be raised or lowered with respect to a frame 2. The platform 3 is raised by an hydraulic ram 9 which swings links 6, 7 about pivots on the platform 3 so that rollers 8 bear down on the frame 2. The tracks, which may be bands of rubber, are driven by an hydraulic motor 10. Large containers may be unloaded by means of two platform trucks (Fig. 6, not shown).

Filed: 1924-10-13
Abstract: 248,807. Atkinson, L. B. Oct. 13, 1924. Testing and estimating.-A standardized test paper for the quantitative determination of gases, e.g. carbon dioxide, is prepared by impregnating the paper with an indication dye, e.g. thymol blue or phenolphthalein, and dipping a portion only of the paper into a caustic alkali solution of suitable strength, the solution being allowed to diffuse into a portion only of the paper so that part remains unmoistened, whereby an approximately uniform concentration of alkali over the moistened area is obtained. In making the test, the treated paper is placed in a holder which is introduced into the apparatus, the atmosphere of which is to be tested, and the time within which the colour change of the indicator dye takes place is noted. The test paper is particularly suitable for measuring the percentage of carbon dioxide in the atmosphere of an incubator.

Title: Closure cap securing and sealing means for pressurized beverage containers
IPC: B65D53/02
Filed: 1962-06-23
Abstract: 1,004,712. Stoppers. F. WELTY and R. D. WELTY. June 23, 1962, No. 24230/62. Heading B8T. A self-sealing closure means for a pressurized beverage container, having an opening defined by a flared flange portion 19, comprises a plurality of flanges 23 secured to the container, each flange having a horizontal portion 24, an intermediate inclined portion 25 and an offset horizontal portion 26, a cup-shaped cap 13 having a depending skirt 21<SP>1</SP> formed with a plurality of circumferentially spaced locking elements 22 which engage the flanges 23 and limit the vertical movement of the cap, and an annular, resilient sealing gasket 12 of L-shaped cross-section placed in the mouth of the container. The cap 13 is positioned so that the locking elements 22 pass between the flanges 23. On turning the cap in a clockwise direction the elements 22 ride under the flanges 23 until they lie beneath the lower horizontal portions 26. As the cap is pushed down into this position it forces the gasket 12 against the surface 20 of the flange 19, thus effecting seals between the portions 32, 33 of the gasket 12 and the contiguous surface of the cap and the surface 20 respectively. A beverage may be admitted into a collapsible bag 30 through a valve 27, secured to the cap 13, and a dip tube 28. At the same time the container is exhausted through a valve 31. The beverage is dispensed from the container by introducing an expelling gas through the valve 31. On removing the cap any excess pressure forces the cap upwards until the elements 22 engage the lower surfaces of the horizontal portions 24 so that the seals formed by the gasket 12 are broken.

Title: A Method of Composting Spent Tobacco Offal.
Inventor: FOGWILL GEOFFREY MILWARD
IPC: C05F11/00
Filed: 1967-05-26
Abstract: 1,190,585. Tobacco offal compost. G. M. FOGWILL. 13 Aug., 1968 [26 May, 1967], No. 24513/67. Heading C1B. Spent tobacco offal is composted by allowing the offal (protected from rain) first to drain itself of excess moisture, then subjecting the offal to a preliminary dehydration step by heating same to reduce the moisture content to 40%, then allowing the offal to compost naturally, and then subjecting the material to a blast of air to remove steam and heat and also to distribute the material over a greater floor area to cause it to lose its coherence and disintegrate. Dehydration may be by passing the offal through a soil sterilizer or comparable machine comprising a rotatable cylinder up which a flame from a burner passes. The natural composting may continue for 1 to 7 days until the material no longer has the odour of tobacco. After the air blast, the material is left in a layer with a maximum depth of not more than one foot and is allowed to remain a further 7 days until an odour reminiscent of silage departs.

Abstract: 1,040,652. Line suspension clamps. BRITISH INSULATED CALLENDERS CABLES Ltd. June 11, 1965 [June 12, 1964], No. 24548/64. Heading H2C. In the overhead line suspension clamp shown, in which the clamping members 2 are of a non- ferrous alloy and wear in the trunnions 7 is prevented by casting them within bushes 9 of wear-resisting material, e.g. stainless steel, the ends of the bushes are slotted and the bushes are cast on to the slots so that relative movement between the trunnions and the bushes is avoided. The trunnions also form caps over the ends of the bushes and if the cooperating end faces of the bushes and trunnions are roughened this may be adequate to prevent relative rotation and may make the bush slots unnecessary. The two parts of the clamp are pivoted together above and held by screws 12 from opposite sides of the clamp. The screws may engage threads cut in wear-resisting stainless steel inserts and bolt-retaining washers of stainless steel may be provided. Siliconaluminium and silicon-magnesium alloys may be used for the clamp.

Title: Improvements in feeding devices for roller-mills
IPC: B02C4/28
Filed: 1927-09-20
Abstract: 277,713. Soc. Anon. Schneider, Jaquet, et Cie. Sept. 20, 1926, [Convention date]. Roller mills.-In a feeding-device for roller mills of the kind in which the rate of feed is regulated by the adjustment of a feed-gate relative to a feed-roller at the bottom of a hopper, thefeed-gate co-operates with a spring-controlled' charging flap arranged in the upper part of the hopper and regulates the feed in accordance with the rate of charging, the feed-gate being adapted to be opened out by hand, without disturbing its original adjustment, and to close the charging flap when thus opened. As shown, the changing flap 1 rocks about a shaft 8 above the hinged partition 3 and is controlled by an adjustable spring 2. The feed-gate 5 is pivotally supported by arms 6 so that it can be adjusted relatively to the feed-roller 4 and has an arm 11 carrying a double-armed lever 7. An adjusting screw 10 in a socket at the lower end of the lever 7 bears against the back of the gate 5, and a roller 9 at the upper end of the lever bears against a cam 14 on the shaft 8. When the normal rate at which the materials are fed into the hopper is exceeded, the downward deflection of the flap 1 under the increased weight causes the cam 14 to rock the lever 7 and gate 5 about the pivots of the gate thereby widening the gap between the roller 4 and the gate 5 so as to increase the feed to the grinding-rollers 12. A pull on the screw 10 causes the lever 7 first to turn about its pivot on the arm 11 so as to close the flap 1 and then to turn about its upper end so as to move the gate into its fully opened position to allow of the removal of any extraneous body from the hopper. The normal position of the gate relative to the roller 4 can be adjusted bv means of the screw 10 and by means of rotatable discs 6<1> to which the pivots of the arms 6 are eccentrically connected.
