Title: Improvements in or relating to a process and apparatus for the treatment of fur-bearing animal skins
IPC: C14B1/00
Filed: 1951-01-04
Abstract: 698,556. Beating furs. HOWARTH, S. W. Dec. 24, 1951 [Jan. 4, 1951], No. 301/51. Class. 138 (i). A process for the treatment of a fur-bearing animal skin to remove earth and the like foreign matter, consists in subjecting the skin to alternate beating blows in opposite directions so as to cause a rapid repeated knocking of the skins to and fro and thereby loosen and remove foreign matter from the fur of the skin. Skins are passed through a slot 24 in a casing 23 and through feed rollers 14, 15. Within the machine the loose skin, as it passes through the rollers 14, 15, is beaten by projections 12, 13 of beaters 3, 4 as it is continually knocked up and down alternately by the projections. After passing through the feed rollers and between the beaters the skin falls into a. compartment 25 from whence it is removed through a trap 27. The feed rollers and beaters are rotated from a motor 11. The beaters which are of hollow cast metal have no sharp projections, apertures or corners and are arranged so that when the diametrical plane through the projections of one beater passes through the axis of the other beater, it will also be at right angles to the diametrical plane through the other projections. Also the projections never touch one another. The feed rollers need not be provided in which case the skin is treated one half at a time by the beaters and then removed from the slot 24 instead of passing to the compartment 25.

Title: Improvements relating to picture communication systems
Inventor: GABOR DENNIS
IPC: H04N3/30
Filed: 1960-01-06
Abstract: 930,841. Television. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 5, 1961 [Jan. 6, 1960], No. 507/60. Drawings to Specification. Class 40 (3). In a television system a reduction in the bandwidth requirement of the transmission channel is effected by transmitting signals representing selected fields or selected frames (2 Î field = frame) and at a receiver deriving from such signals further signals representing interpolated approximations of the fields or frames not transmitted and combining both sets of signals to form a composite signal suitable for conventional reproduction. By transmitting the selected fields or frames at a rate such that the normal duration of the selected and unselected fields or frames is taken for the transmission a bandwidth reduction factor equal to the ratio of the normal transmission time of the selected and unselected fields or frames to that of a single field or frame is realized. In a preferred way of carrying out the invention the received low-rate selected field or frame signals are stored in a first cathode-ray tube store from which they are subsequently read-out (at normal scanning rates) to form the first field or frame of the composite signal and, simultaneously with the first storage operation, are also stored in duplicate in interlaced fashion in a second store from which the interpolated approximations to the " missing " fields or frames are derived by comparison of alternate lines of each field or corresponding lines of alternate frames. A linear form of interpolation may be effected but in areas involving sharp contours (e.g. transitions between extreme black and white) a process termed contour interpolation is employed. This process involves the arresting of the motion of the scanning beam which " reads " one of the two lines between which interpolation is required when a sharp contour is reached and, at this instant, the doubling of the scan velocity of the beam scanning the other line. This latter scan continues at doubled velocity until a sharp contour in such other line is reached at which instant the scanning is arrested and the first beam caused to scan at doubled velocity until it reaches a position corresponding to that of the second beam. Thereafter both beams scan their respective lines at normal velocity until other contours are reached. Instead of employing cathode-ray tube stores magnetic stores or delay line stores or combinations of both may be employed.

Abstract: 1,003,825. Crimping fibres. EASTMAN KODAK CO. Jan. 5, 1962 [Jan. 9,1961(2)], No. 525/62. Heading D1F. [Also in Division A2] A crimped tow, the continuous filaments of which have an average angle of crimp less than 100 degrees is opened e.g. pneumatically, under tension and a positive retarding means is applied to the moving tow to restrict its advancement and thus compress the crimps to an average angle of crimp not exceeding 100 degrees. The filaments may be of acrylics, cellulose acetate or regenerated cellulose, polyesters or polypropylene. The final crimped tow may be formed into a narrow rope from which tobacco smoke filters are produced. In the operation of the apparatus shown, a crimped tow e.g. up to 100,000 total denier, is passed through the centre of an annular converging jet of compressed air, supplied to inlets 24 and escaping from an annular passage 20 formed by the end 19 of a tube 11 and a tapered orifice in a plate 13. The jet strikes the slower moving tow at an acute angle and creates suction in the tube 11 which thereby inhales the tow. The filaments are separated by air penetrating the tow and expanding explosively towards the walls 21 of a tube 14: they are reunited by the convergence of the walls 21 and are guided into a throat 22 wherein they continue to be agitated. The air and filaments then pass into a discharge chamber 23 and, on emerging therefrom, the tow is retarded by adjustably inwardly directed curved portions of resilient tongues 27 to compress the crimps. Specifications 765,961, 765,962, 765,963, 909,940, 933,227 and 986,393 are referred to.

Abstract: 764,029. Capsuling bottles. CLAYTON, Ltd., G. S. Jan. 7, 1955, No. 574/55. Class 125(2). In apparatus in which a membrane 7 is deformed by liquid pressure to crimp a capsule round a bottle neck, the head 5 is mounted on the bottom of a hollow shaft 3 slidably carried on a bracket 2 fixed to a vertically reciprocated shaft 1 and the shaft 1 in descending first lowers the head 5 on to the bottle and then, through abutment 25, actuates a ram 10 which forces liquid through a flexible pipe 9 and the shaft 3 to the head 5. To prevent excess pressure being applied to the membrane, a piston 23 is forced down against a spring 24 when a desired maximum pressure is exceeded. The cylinder 13 of ram 10 is surrounded by a liquid reservoir 17 from which make up liquid can flow to the cylinder through a bore 15 and bores 26 in the piston of the ram. When the ram is at the top of its stroke, the reservoir and the cylinder communicate through port 14 to equalize the pressure. The abutment 25 may be moved aside in the absence of a bottle so that the ram is not actuated.
