Abstract: 663,738. Photographic projection printing apparatus. TRIGGS, W. W. (Diebold, Inc.). March 8, 1948, No. 7151/48. Class 98 (i). A lens and film supporting means for photographic microfilm copying apparatus of the kind in which the lens is mounted in a support which also carries means for positioning the film in the rear focal plane of the lens to have focused thereon by the lens an image of the copy carried on a copy support positioned in the apparatus at a fixed distance from the lens support, is characterized in that the lens support includes a frame which:carries means for positioning the film in the focal plane of the lens, and means defining a slit overlying the lens for limiting the area of film exposed by the lens, the frame being formed so that it is readily mountable in the apparatus at the required distance from the copy support and readily demountable therefrom, whereby the lens and film positioning means are attachable to and removable from the apparatus as a unit, their relative - position remaining the same during such attachment or removal. As shown, Fig. 4, the lens 23 is mounted in a frame 22. A pillar 24 slides vertically in the frame 22, and has a perpendicularly extending arm 26 which has a rounded undersurface over which the film F passes. The pillar 24 is adjusted and clamped by a screw 25, preferably before the frame is mounted on a wall 10 of the apparatus, at a fixed distance from the copy. A slit is formed parallel to the arm 26, in a cap 27 on the frame 22, and the copy and film are moved continuously to produce an image of the copy on the film in known manner. The film F may pass over a roller bearing mounted on and parallel to the bar 26. Alternatively, lens 23 is mounted in a frame 33, Fig. 6, having a cap 31 with a convex cylindrical outer surface in which a slit 32 is formed and over which the film F passes. These arrangements may be modified by providing twin lenses side-by-side and a pair of corresponding slits, so that two images of the copy are formed side-by-side on the same film.

Abstract: 1,199,558. Preserving g beverages. BROOKE BOND LIEBIG Ltd. 20 March, 1969 [10 Feb., 1969], No. 7175/69. Heading A2D. [Also in Division C6] A process for the preparation of a substantially non-ethanolic or low ethanolic beverage involves extracting an ethanolic beverage with a low boiling point organic solvent in which ethanol is substantially insoluble to remove the flavouring materials, removing or partially removing ethanol by distillation from the beverage resulting from the solvent extraction, removing the solvent from the extracted flavouring materials e.g. by distillation, returning the flavouring materials to the ethanolfree or low-ethanol beverage and adding a preservative to the beverage. Distilled water is then added in an amount to make up the original volume. Glycerol or sorbitol may also be added. Solvents: isopentane, trifluorochloromethane and tetrafluorodichloroethane. Preservatives: benzoic acid, sodium benzoate, sulphur dioxide (as sodium metabisulphite) and diethyl pyrocarbonate. The preservative is preferably added after the distillation step. Up to 75 per cent by weight of the natural ethanolic beverage may be added to a substantially non-ethanolic beverage prepared by the process, to obtain a low ethanolic beverage of desired natural flavour and ethanol content. The examples are directed to the preparation of non-alcoholic sherries and vermouth, and of a low-alcoholic sherry.

IPC: F16C33/22
Filed: 1927-03-17
Abstract: 267,947. Petard, M. R. March 17, 1926, [Convention date]. Packing, non-metallic; stuffing-boxes, substitutes for; connected to source of high or low pressure.-A shaft A is guided or supported by rings 1 - - 11, Fig. 1, of rubber or other resilient material separated by rings 2 - - 12 of harder material which do not touch the shaft but of which some, or all, may support the latter should the rubber rings fail. A screw E or other means may compress the rings so as to take up wear, &c. Lubricant under pressure is led through passages OP to some of the cavities between the rubber rings 1 and is drained away through passages CV from the remaining cavities. Some of the cavities may carry a different fluid to the others to dilute any product tending to leak from the machine or to collect the same should it be valuable. Each bearing may have a plurality of ducts OP, or a single duct CP may be common to a number of machines. The ducts CP, CV may be fitted with valves so as to pass through the device liquids or fluids to expel the lubricants, or clean or dry the device, or to refill the device by other fluids during its periods of rest. The bore of the rings 2 may be lined with rubber or like materials. If the device is to be used under water the duct CP may be omitted and ducts adjacent the rings 2, 6, 10 may communicate with the surrounding liquid and the cavities adjacent the rings 4, 8, 12 may be connected through the passage CV to the suction side of a pump. During the period of rest. and to minimize corrosion the water in the device may be expelled by passing steam through the duct CV. The rings may be split to avoid threading the parts on the shaft. In a modification the rubber rings 1 - - 11 and the separating rings 2 - - 12 are replaced by helices, one helical cavity being connected to a lubricant pressure supply device and the other to the exhaust thereof. The helices may be rectangular, trapezoidal or of other section. In a further modification a rubber bearing surface has two sets of helical grooves, each forming a lubricant channel and accommodating a helical spring. The rubber helices may have a reinforcing core and the rotation of the shaft may tend to twist the springs to tighten the parts. The Specification as open to inspection under Sect. 91 (3) (a) describes also a bearing formed of a rubber helix the coils of which engage the coils of a hard helix, a space between the latter and the shaft forming a lubricant channel. In another modification, a bearing with a helical rubber bearing surface a, Fig. 5, has a helical spring r therein, wear being taken up by twisting the ends e, e<1> of the latter. This subjectmatter does not appear in the Specification as accepted.
