Title: Improvements in and relating to stencils for duplicating
IPC: B41N1/24
Filed: 1927-03-15
Abstract: 286,466. Simon, H. March 15, 1927. Stencils.-In duplicating-machine stencil sheets of the kind comprising a sheet of Yoshino paper coated with a composition which includes oily softening-agents, a protective coating which is impervious to the oily material, is applied to the sheet for the purpose of protecting the platen and the type of the typewriter and the impression roller of the duplicator against the injurious action of the oily material. The protective coating may be applied to both surfaces of the stencil sheet, or it may be applied to a separate covering sheet. The protective coating may consist of proteins, natural or artificial resins, esters or ethers of resins, cellulose esters or ethers, or nitrated cellulose-ethers. Salts of fatty acids, or acids derived from acid resins may be added to the coating or may themselves form the coating. Softening-agents, such as glycerine or sugar, may also be added. In examples, the protective coating comprises (1) an alkaline solution of casein to which glycerine or sugar is added; (2) an alcoholic containing varnish and sodium oleate; and (3) an alcoholic solution of palmitic acid and sodium oleate.
Patent GB-794349-A (GB)
Title: Method of treating noble metal and alumina catalysts with hydrogen and hydrogen halide
IPC: C10G35/085
Filed: 1955-03-11
Abstract: Platinum group metal on alumina catalysts are activated or reactivated in the presence of iron by treatment, in the substantial absence of hydrocarbons and carbon, with a gaseous mixture of hydrogen and hydrogen halide, the hydrogen halide partial pressure being not more than 15 per cent of that necessary for the formation of iron halide at the prevailing conditions. The halide content of the catalyst is increased to 0.05-2 per cent and preferably to an equilibrium value of about 0.4-0.5 per cent by weight of chloride (or an equivalent quantity of other halide) for each 50 square metres per gram of alumina surface. The process prevents poisoning of the catalyst with iron halide formed by reaction of hydrogen halide with iron present in the apparatus or in filling materials.  The treatment may be used in catalyst preparation or after oxidative regeneration of the catalyst.  Temperatures of 700-1000 DEG  F. and pressures of 1-40 atmospheres are suitable for the treatment.  The process may include a preliminary treatment with hydrogen alone, or a subsequent treatment with hydrogen alone to remove halide above the equilibrium amount.  Graphs are provided showing the equilibrium hydrogen chloride partial pressure at various temperatures and pressures. Examples describe the treatment of chlorine-containing platinum on alumina catalyst which has been used in the reforming of naphthas; after regeneration with an oxygen-containing gas to remove coke, the catalyst is treated with hydrogen containing specified small amounts of hydrogen chloride.

Title: Improvements in or relating to resilient load-transmitting devices
IPC: F16D3/76
Filed: 1947-03-17
Abstract: 629,354. Resilient mountings. THIRY L. F. March 17, 1947, No. 7317. Convention date, March 20, 1946. [Class 108 (iii)] [Also in Group XXIV] In a resilient mounting of the kind in which a resilient member is disposed and preferably compressed between two opposed rigid surfaces so as to be in rolling contact with each over a substantial area, the member is attached to one or both of the surfaces over a part only of the respective area or areas so as to prevent permanent displacement of the member along the surfaces without unduly restricting the rolling action. As shown, a natural or synthetic rubber ring 5, Figs. 1 and 2, is compressed between the outer surface of a seamless steel, brass or other tube 1 supporting by a flange 9 a load 12, and the inner surface of a similar surrounding tube 2 mounted by a flange 10 on a support 11. The flanges 9, 10 may be welded or riveted to the tubes. The ring 5 is secured to the tubes over areas 15, 16 occupying suitably from one-fourth to one-half, and preferably about one-third, of the respective total contact area. The cross-section of the ring when unstressed may be circular or rectangular with rounded corners. When the mounting is fully deflected under load, the flange 9 engages a rubber bumper 13 on the tube 2. Adhesion over the areas 15, 16 may be effected by coating the corresponding portions of the rubber and/or the tubes previous to assembly with thermoplastic hard - drying resinous materials such as rubber chloride, heatplastic rubber isomers or certain polyvinyl butyral modified phenol formaldehyde resins. After the coating has hardened, the mounting is assembled and bonding obtained by rapidly heating the tubes sufficiently to soften the coating, preferably without any prolonged heattreatment of the rubber. The remaining contact portions of the rubber and/or the tubes may be pre-coated with adhesion-preventing materials such as sodium silicate or gelatin, dried to a hard surface to allow assembly without smearing. In this case, the entire surface of the rubber may be subsequently coated with a hard-drying adhesive such as rubber chloride solution, the mounting being assembled before or after this has dried. Where the ring is not in a compressed state when assembled, it may be initially partly or wholly of uncured rubber and be vulcanized when in position with, if desired, simultaneous bonding using adhesion inhibitors as before. A heavyduty mounting giving progressive compression of the resilient member with increasing load comprises two rubber rings 44, 45, Fig. 8, secured as before to the sides of a tapering annular recess 38 in a support 36 and to the sides of a complementary annular projection 39 in a loaded member 35. The rings 44, 45 may when unstressed be of circular section or be shaped sectionally as parallelograms with rounded corners to conform roughly to their working spaces. Deflection under load is limited by a rubber bumper 55, and a drain plug 54 is provided.

Abstract: 1,270,623. Feeding sheets. HENRY SIMON Ltd. 23 Dec., 1970 [17 Feb., 1970], No. 7445/70. Heading B8R. A pile separating means, e.g. a driven roller 32, which in operation separates sheets, e.g. corrugated boards, from the top of a pile S and feeds them to conveyer means, e.g. inclined endless belts 23 and horizontal endless belts 14, 19, forming a conveyer of adjustable length, is provided with control means for sensing the pile height and for lowering the separating means as the pile is consumed and raising it for reception of a new pile. At the beginning of a pile separating cycle sheets are separated relatively quickly until a limit switch S4 indicates a stack of certain height has been formed on the table 10a of a sheet processing machine 10 and starts the machine 10, the speed of separation and conveyance then being slowed down. Separating roller 32 descends under its own weight as the pile S is consumed until its mounting arm 33 pivotally attached to the end of the inclined endless belt conveyer 23 actuates a limit switch S3, this causing an hydraulic motor 28 to pivot the endless belts 23 downwardly about their drive roller 16 until arm 33 actuates limit switch S2. This intermittent lowering takes place until all sheets have been separated from a pile thus actuating a pile sensing limit switch S1 which causes the endless belts 23 and separating roller 32 to be raised to their uppermost position and roller conveyer 11 to drive a new pile into position.

Abstract: 1,156,615. Doping semi-conductor material. CORNING GLASS WORKS. 16 Feb., 1967 [23 Feb., 1966], No. 7492/67. Heading H1K. A plurality of receptacles 50 for semiconductor material are passed in sequence through an elongate heating zone such as the tubular furnace core 13, the arrangement being such that the content of each receptacle is isolated from the contents of the neighbouring receptacles. As shown this is achieved by fitting a D-shaped bottom liner 15 in the furnace core and making the receptacles consist of a tray protion 51, Fig. 4, and a barrier wall portion 52 which fits the space between the liner 15 and the core 13. Alternatively, the liner 15 may be omitted and the receptacles consist of a D-shaped base with a circular barrier wall at one end (Fig. 5, not shown). The apparatus is used to dope the contents of the receptacles, a series of heaters surrounding the core ensuring that the temperature in it increases from each end toward the centre, so that the contents of the receptacles are gradually heated and then gradually cooled as they pass through. Conduits 30 to 34 supply a suitable atmosphere to the various regions of the heating zone. The atmosphere is inert as supplied by conduits 30, 31, 33, 34 to the input and output ends of the path of motion of the receptacles through the furnace and is a doping atmosphere (containing e.g. POCl 3 ) at the maximum temperature region fed by conduit 32.
