Abstract: 757,321. Squeezing fibre webs. SPINNBAU GES. March 4, 1953 [May 8, 1952], No. 5962/53. Class 120 (1). [Also in Group XXIX] In apparatus for squeezing carded fibre fleece comprising two opposed pressure rollers, not in direct contact with a fluid pressure medium, supported along their whole length by non-rotatable beams with a pressure-transmitting member interposed between the outside of one or each roller and its beam so as to leave the end bearings of the roller free of pressure, a non- rolling pressure-transmitting member, or a plurality of such members in alignment, is used extending along the full length of a roller, such member or members being supported outwards of the roller and being of an elastically yielding nature or being acted upon by a yieldable pressure transmitting part or parts. Pressuretransmitting members may be made of an elastic material, such as bronze or plastic, which has a lower modulus of elasticity than the rollers or beams; or elastic pads or cushions, e.g. rubber plates, or resilient mechanical, pneumatic or hydraulic pressure systems may be interposed between the pressure transmitting members and the beams. In one arrangement Fig. 4, pressure is applied to rollers 1, 2 by hydraulic cylinders 11, 11<SP>1</SP> interposed between the beams 6, 8 and the pressure transmitting members 7, 7<SP>1</SP> which are divided up, by oblique divisions 15, 15<SP>1</SP>, into individual longitudinal sections. Further members 14, 141 may be interposed between members 7, 71 and the cylinders. Common supply lines 12, 121 equalize pressure between the cylinders. In another arrangement, Fig. 6, a hollow tube 19 of rubber or thin-walled metal is interposed between each beam 6 or 8 and the transmitting member 7 or 71. Each tube is closed at one end, where it is provided with a pressure gauge and regulating valve, and at the other end is connected to a supply of pressure medium. Pressure in the two tubes may be similarly variable by a hand wheel connected by screw-threads to the pistons of pressure-regulating hydraulic cylinders. Alternatively a supply pump may be connected to the two tubes through check valves one of which closes at a determined pressure while the required working pressure is applied to the other. The roller bearings may be connected by a compression spring whereby the rollers will react to a reduction of applied pressure. Heat may be applied to the rollers by means of a heating element located in one of the tubes 19. The pressure supplying member 13, Fig. 4, and the tubes 19, Fig. 6, contain an air space permitting the pressure system to yield. Specification 743,485 is referred to.

Abstract: 277,928. Medgyes, K. Sept. 25, 1926, [Convention date]. Indiarubber, seaming; preventing adhesion of unvulcanized surfaces.-A dusting preparation for preventing undesired adhesion of unvulcanized rubber sheets consists of a substance which loses its anti-cohesive properties when the sheets aredie-stamp welded with hot tools, whereby weakening of the welded seams is avoided. The loss of anticohesive tendency may be due for example to the melting of the preparation, to its solution in the rubber, or to its decomposition into volatile products. Examples of suitable substances are naphthalene, acetanilide applied in alcoholic solution, hexamethylenetetramine, thiocarbanilide applied in aqueous suspension, organic salts of metals such as fatty acid salts of lead, zinc, &c. The stamped articles may be treated with the known dusting powders or may be vulcanized in hot water to prevent adhesion.

Abstract: 1463234 X-ray diagnostic apparatus DIGITAL INFORMATION SCIENCE CORP 14 Feb 1975 [15 Feb 1974] 6395/75 Headings H4F and H5R Apparatus for examining a slice of a body by orbiting in incremental steps an X-ray source 96 and associated detector 98 around the body, and between each such orbital step laterally moving the source and detector across the body, the resulting absorption output signals being fed to a computer for processing to thereby derive a pictorial representation of the body slice. The apparatus comprises a vertical frame 20 having an opening therethrough of a size sufficiently large to permit a patient supported on a table to move therethrough. A carrier frame 60 having an opening co-extensive with the opening in frame 20 is supported on frame 20 and is rotated relative thereto around the patient, the source 96 and detector 98 being mounted on a third frame 80 which is movable transversely in the plane of frame 60 to effect the above lateral scanning action. The frame 20, and thus also frames 60 and 80 carried thereby, may be tilted about axis 21 relative to the patient so that slices of the patient other than vertical slices may be examined. This tilting is effected by adjustable bars interconnecting the top of the frame 20 with the top of a fixed frame 12 (Fig. 5, not shown) and when the frame 20 is tilted the table carrying the patient is automatically lowered. The table, or rather a stretcher, carrying the patient may be incrementally moved to thereby accurately locate the patient relative to the source and detector, the stretcher having a rack formed in its bottom side which engages with a stepping motor on the table (Fig. 5, not shown). Counterbalance weights 70a and 70b are provided on frame 60 which are moved in the opposite directions to the source and detector as the frame 80 (and thus the source and detector) are transversely moved across the patient. The apparatus also includes a shutter arrangement which interrupts the X-ray beam from source 96 until such time as the patient approaches the beam (Figs. 11A-11B, not shown), the shutter being actuated when a light beam is interrupted by a band of X-ray transparent material which is opaque to the light that is wrapped around the patient's body or head.

In a process of sealing gas-filled glass vessels, e.g. incandescent electric lamps, having a gas filling above atmospheric pressure, a sealed container filled with gas at high pressure is enclosed in the vessel and is opened after sealing. The container may be filled with the filling gas mixture, e.g. nitrogen and a rare gas, or with one or more components of the mixture. A metal container, e.g. a thin-walled iron tube with one end welded and the other closed by a plug of metallic solder having a melting-point above the temperature occurring during sealing, e.g. above 400 ‹-500 ‹ C. may be used. Alternatively, both ends may be closed by welding and one or more opening provided in the walls of the container and closed by solder. The solder may be melted after sealing by highfrequency heating. Alternatively, the container may be opened by heating by current flowing through a resistance wire embedded in the solder, one end of the wire being connected to one of the filament supports and the other to a separate lead. To avoid damage to the contents of the lamp by the escaping gas, the container may be arranged in the neck of the lamp so that the gas escapes in the direction of the lamp base.
