Abstract: 1,039,317. Filters for liquids. W. MAYER, W. KOCH, K. U. MAYER-RUDOLPHI and H. H. MESSNER [trading as SCHUMACHER'SCHE FABRIK]. June 15,1964 [June 15,1963], No. 24733/64. Heading B1D. Each of a number of ceramic filter tubes 40 has secured to its periphery, by adhesive or tightness of fit or both, a resilient sealing ring 42. The length of a ring is greater than the depth of a corresponding shouldered recess 44 in a partition 26. Sealing is effected by forcing the rings into the recesses by a common pressure plate 50. Pressure plate 50 is forced down on to rings 42 for this purpose by a fixed annular flange 56 by screwing down bolts 20 during assembly of container halves 12, 14 and partition 26. The filter tubes are thereby also supported. In Fig. 4, (not shown), a partition is supported by a packing ring on an inwardly-directed flange in a one-part casing. Each filter tube depends downwards with a small clearance through a hole in the partition and is supported by a sealing ring which fits tightly around its upper (open) end and rests on the partition. Each sealing ring is surrounded by a bush of shorter axial length than itself. The rings are in this case compressed by a pressure plate forced downwards by nuts engaging its upper surface and screwed down on to protruding bolts secured to the partition. In Fig. 3 (not shown) the filter tubes consist of perforated metal covered by a thin bonded or unbonded fleece.

Abstract: 360,525. Wrapping-machines. FORGROVE MACHINERY CO., Ltd. and GROVER, F., Oakhurst Avenue, Dewsbury Road, Leeds. Aug. 20, 1930, No. 24895. [Class 94 (i).] In a wrapping machine which includes a rotary folding device and an oscillating device in which further folding takes place, the articles 1 are fed by a belt 2 in front of a plunger 3, which thrusts the leading one, with a wrapper 4, between jaws 7, 8 mounted for intermittent rotation about an axis 12. During this movement, the leading surface of the wrapper is engaged by a finger 21, resiliently mounted on a slide 21<1> so as to yield against the action of a spring and to guide the article and wrapper into the jaws. An extension 33 on the finger engages a roller 34 on the jaw 8, and slightly opens the jaw against the action of a spring to facilitate the insertion. Two pairs of jaws are mounted on the axis 12, which now turns through 180‹, a semicircular plate 13 turning the flap 4a of the wrapper into the position shown in Fig. 9. At this point, a finger 22 rigidly mounted on the slide 21<1>, co-operates with a resiliently mounted finger 23 to transfer the partially wrapped article to the position 1b between grippers 15, 16, while another rigid finger 24 on the slide removes the previously treated article on to a delivery table 20. During the transference by the fingers 22, 23, a stationary member 14 turns up the flap 4a so that the wrapper is in the form of an open-ended tube when the article arrives between the grippers 15, 16. The grippers are mounted on arms 17, 18 adapted to oscillate about a pivot 19 and the article is carried downwards so that folders 27 form the first end tucks 4d, Fig. 11, in the ends of the wrapper. Folders 28, 29 approach to turn in the tucks 4b, 4c, the grippers 15, 16 moving slightly further downwards to nip the folds. The grippers return the article to the original position for removal by the finger 24. The outstanding flaps may, if desired, be folded down and secured by adhesive in any suitable manner. The resiliently mounted fingers 21, 23 may be disengaged at the appropriate moments by the action of a stationary cam 32 on rollers 31 mounted on extensions 30 of the fingers.

Patent GB-1347112-A (GB)
Title: Printing and copying employing materials with surface variations
IPC: G03G5/082
Filed: 1971-04-19
Abstract: 1347112 Printing surfaces ENERGY CONVERSION DEVICES Inc 19 April 1971 [10 April 1970] 25185/71 Heading B6C [Also in Divisions G2 G4 and H4] Relates to a method of forming an image, e.g. in a printer, in which in response to a pattern of energy (e.g. light, electrons, electrical current or heat) corresponding to the image the surface structure of a layer of amorphous semi-conductor material is changed, the layer being then wetted with a solution which adheres to these "changed" areas only. The change in surface structure includes a change from an amorphous or disordered stable state to a crystalline or more ordered stable state, i.e. from a smooth to a rough grainy surface, or vice-versa, but also includes other changes in local order to changes in phase which result in new bonds between atoms resulting in new structural or chemical configurations which provide different wetting ability. In a first embodiment a laser beam or strong light beam is directed via a transparency on to a layer of amorphous semi-conductor material disposed on a drum to change it from its amorphous to its crystalline state. The image thus formed is inked and transferred via a rubbercovered cylinder to a document (Fig. 1, not shown). Many copies may be made before a focused line of high intensity electromagnetic energy is scanned across the layer to raise its temperature to its melting point, the material returning to its amorphous state upon rapid cooling. In a second embodiment (Fig. 3, not shown) a laser beam is modulated and raster scanned over the layer which is initially in its crystalline state and is thus selectively converted to its amorphous state. Instead of modulating the beam a mask with alpha-numeric characters may be disposed in the scanning beam path. A wetting solution (e.g. water and alcohol) is then applied to the entire surface and adheres only to the crystalline regions. Ink which is repelled by the wetting solution is next applied and thus only adheres to the amorphous regions. An offset roller transfers the ink on to a document. In a further embodiment (Fig. 5, not shown) resistor elements are disposed on a glass substrate and covered with a layer of the amorphous semi-conductor material. Electric current is selectively applied to these resistor elements, the resulting heat generated thereby changing the amorphous material into its crystalline state. The resistor elements may either be such that a number of alpha-numeric characters may be formed, or may comprise a matrix of points. Ink is then applied thereto for printing. Permanent images may be formed on the layers of amorphous material by allowing the ink to dry thereon. Varying grey shades may be printed and selected areas of the image may be erased for correction purposes.
