Title: Improvements in cigarettes with filter plugs or other internal mouthpieces, and methods and machinery used in their production
Inventor: SWEENEY JOSEPH NEAL
IPC: A24D1/12
Filed: 1950-01-28
Abstract: To retain the tobacco of an internal mouthpiece cigarette in position until the cigarette has been completely smoked, whilst allowing recovery of substantially all the tobacco from such a cigarette when rejected unsmoked, the cigarette paper enclosing the tobacco is internally coated adjacent the mouthpiece with an adhesive containing fire-retardants and which is so applied or of such a character as only to adhere appreciably to the tobacco under the heat or other effects of smoking.  Suitable adhesives which, after operative application while wet, are effective when dried, and must therefore be wholly or surface dried after application to the cigarette paper before it comes in contact with the tobacco, are composed of (1) 67 per cent. by weight of a highly dextrinized starch containing approximately 35 per cent water, 21 per cent by weight of ammonium sulphate and 12 per cent by weight of water, or (2), according to the Provisional Specification, a highly dextrinized starch and an alum, to which may be added a powdered thermoplastic resin such as polythene. Suitable adhesives which, after operative application, are not effective when dried without heating are composed of (1) 37 per cent by weight of a highly dextrinized starch containing approximately 35 per cent. water, 39 per cent. by weight of water, 15 per cent by weight of ammonium sulphate, 7 per cent by weight of stearic acid, 1 per cent by weight of borax and 1 per cent by weight of the substance known under the Registered Trade Mark "Teepol" or (2), according to the Provisional Specification, gum tragocanth and an alum.  Reference has been directed by the Comptroller to Specification 689,897 [Group VI]

Title: Improvements in or relating to Centrifugal Machines or Separators.
Inventor: STURGEON ROBERT ALEXANDER
IPC: B04B11/05
Filed: 1918-02-11
Abstract: 123,797. Sturgeon, R. A. Feb. 11, 1918. Density separators.-The separating drum A has a fixed cover A<1> and a reduced opposite end a, which is closed during separation of the material by a cover C<2> carried by a sliding sleeve to which are attached a piston C and a baffle-plate C<1>. The piston C is subjected to pressure of liquid under treatment due to centrifugal force, and this action closes the opening a. When separation is completed, other liquid is supplied above the piston C from the pipe D and pushes down the piston C which expels the separated solids or heavy liquids deposited on the wall of the drum. This auxiliary liquid escapes through openings A<3>, and the piston is again raised when more mixture is introduced through the hollow shaft B. Openings C' permit escape of the lighter liquid constituent of the mixture.

A method of manufacturing a transformer core comprises coating strips of magnetically orientated material with a ceramic enamel binding agent which melts at a temperature between 775‹ and 825‹ C., but which will not be destroyed by a regenerative annealing process, drying the binding agent, forming the core from the strips, and annealing the core after it has been cooled in a non-oxidizing atmosphere at a temperature of 825‹-875‹ C. The strips may be previously coated with a ceramic insulation which withstands temperatures of more than 1000‹C. Alternatively, uncoated strips may be used, a powdered substance of 5-10 microns graining, for example carbides of heavy metals, which is not soluble in the molten enamel, being added to the enamel. The core is cut into U-shaped pieces and the contact surfaces ground flat if necessary. The U-shaped pieces may be formed directly from cut strip and the contact surfaces aligned and ground before the regenerative annealing process.

An adjustable pressure limiting valve 1 in the control circuit of a hydraulic motor (not shown) for driving a cyclically operable machine e.g., a paper cutter (not shown) is controlled so as to vary the maximum operating pressure of the fluid by means of a rod 6 which is cyclically displaceable from a reference position in synchronism with each operating cycle of the machine. As shown the control rod 6 is moved by a lever 16 having one end adjustably held by a screw 20 against a spring 19 and having the other end 17 abutting a cam 9 driven by a rotary shaft 10 of the machine. Inward movement of rod 6 increases the operating pressure limit and the operating range is thus at its highest when the lower end 17 of lever 16 abuts a stop 21.

Filed: 1923-02-01
Abstract: 219,915. Nistri, U. Feb. 1, 1923. Photographic surveying-instruments. - Relates to that method of photographic surveying in which pairs of aerial photographs are taken oi successive areas of the ground using a camera of known focal length, and in which the required plan is produced by simultaneous optical projection of the resulting negatives of each pair disposed in the relative positions which they occupied at the time of the exposures, each of the projecting lenses having a principal distance corresponding to the focal length of the camera. The photographs of one pair of the series cover an accessible portion of the ground which includes three, or preferably four, points of known position which are used for triangulation, but additional triangulation points are obtained indirectly by providing the camera 11, Figs. 1 and 2, with a second lens 2 by which an area of distant ground along the line of travel of the airship is photographed simultaneously with the photographing by the main lens 1 on another portion of the same negative of the area vertically below the airship. For this purpose a mirror 5, Figs. 1 and 2, or prisms 3, 4, Fig. 3, of adjustable inclination, are used in front of the lens 2. The distant areas are also photographed by the lens 1 when the airship is vertically above them at an earlier or later stage in the survey. Each of the two projecting apparatus is provided with lenses 9, 10, Fig. 6, corresponding to the lenses 1, 2 respectively of the camera, and an adjustable mirror 18 or prism system is used in front of the lens 10. Micrometer devices 7, 8 are provided for adjusting the relative positions of the lenses 9, 10. The correct orientation for the projection of the first pair of negatives is determined by using a screen formed in four sections separately adjustable in accordance with the known positions of the triangulation points in the photographs taken by the lens 1 as described in Specification 182.912. The four-part screen is then used in conjunction with the projected images of the photo. graphs on the same negatives taken by lens 2 to determine by adjustment of the sections the location and heights of points conveniently chosen in the distant area, and the data so obtained are utilized in determining the correct orientation of the two negatives when the other photographs of that distant area., taken at an earlier or later stage by the lens 1, are being projected.
