Title: Improvements in processes of bleaching and dyeing furs
IPC: D06L4/30
Filed: 1925-11-25
Abstract: 265,324. Dehn, F. B., (Stein Fur Dyeing Co., Inc.). Nov. 25, 1925. Bleaching, processes and materials for.- Animal fibrous materials, such as furs, are bleached rapidly, without weakening the leather of the skins or impairing the natural texture and strength of the hair, and may be dyed subse. quently to light or other colours, if first treated with ferrous salt (e.g. porous sulphate) as a protective agent, with or without ammonium chloride as a stabilizing agent. Thus the fur skins may be washed three hours with an alkaline solution, e.g. sodium carbonate, and then soaked in an aqueous solution containing from 0.5 to 5.0 per cent by weight of ferrous sulphate, with a similar amount of ammonium chloride, after which they are rinsed and hydro-extracted, prior to immersion in a bleaching solution such as a 3 to 5 per cent by volume solution of hydrogen peroxide. Ultimately they are washed and dyed by any suitable process, with or without mordanting. The method may also be applied to skins previously unsatisfactorily dyed. Specification 264,969 is referred to.

Title: Electrophotography
IPC: G03G5/147
Filed: 1956-10-01
Abstract: 853,307. Electrophotographic processes. MINNESOTA MINING & MANUFACTURING CO. Oct. 1, 1956 [Sept. 30, 1955], No. 29929/56. Drawings to Specification. Class 98(2) [Also in Groups XXXV and XXXVI] A developed electrophotographic image is produced by exposing a substantially electrostatically neutral photoconductive copy sheet to an original to be copied, producing a corona discharge between an electrode and the copy sheet, and simultaneously with the production of the discharge directing an aerosol of developer particles into the path of the corona discharge, the copysheet may remain exposed to the image during the development step or the image may be removed just prior to development. The developer aerosol may be produced by heating a wire or belt coated or impregnated with the developer, so that a cloud of particles rises into the path of the corona discharge. Such a belt may be heated momentarily by moving a heated crank against its underside by moving it over a hot wire or by heating the belt with infra-red radiation. The developer particles may be directly visible on the photoconductive sheet or they may be of a substance which interacts with a material on the sheet or causes reaction between materials on the sheet. Thus it may be a solvent which causes spreading of dry dye particles contained in the sheet, or it may be a solvent which removes or transparentizes a light coloured or opaque outer layer covering a contrasting underlayer. The developer particles may be of a dye such as Alizarine Irisol N, Brilliant Oil Blue, Anthraquinone Sky Blue B Base, Oil Red O, Oil Yellow, Oil Brown O, Oil Brown N and Celanthrene Red YP. The dyes may be mixed with waxes or plasticizers to assist them in adhering to the image sheet. Dye particles such as Alizarine Irisol N may be incorporated in the photoconductive coating, in which case the developer is a solvent for the dyes such as resorcinol. Other volatile substances which act as solvents are the amyl or butyl monoethers of ethylene glycol, cyclohexanol, acetophenone, stearic acid and #-hydroxyquinoline. Where the image is produced by chemical reaction, ferric stearate may be incorporated into the light-sensitive coating, and pyrogallol or catechol in aerosol form used as the developer. The ferric stearate may be replaced by ferric laurate, myristate or caprylate and the developer may be #-hydroquinoline, propyl gallate, protocatechine acid, catechol, gallic acid or resorcinol. Other pairs of reactants and developers specified are nickel stearate and dimethylglyoxime; manganese, magnesium, copper, silver or cobalt soaps and phenolic materials; heavy metal soaps with thiourea, benzotriazole or 2-mercaptobenzimidazole; and stabilized diazonium salts and phenolic materials. The invention may be employed to produce multi-colour prints by repeating the process using different coloured dyes. Specification 853,308 is referred to.

Filed: 1935-10-31
Abstract: 451,996. Delivering measured quantities of liquids. HARTMANN, C. W., Lyngby, near Copenhagen. Oct. 31, 1935, No. 30125. [Class 106 (v)] In apparatus for delivering measured quantities of liquid wherein a rotatable member 4 is provided with a diametrical channel 5 forming a measuring chamber at each side of a piston 6 sliding freely in the channel, means are provided for removing the piston in a lateral or horizontal direction in order to replace it by another of a different length so as to adjust the amount of liquid delivered. The member 4 rotates within an outer casing 11 formed at one side with a lateral aperture 15 normally closed by a lid 16. On removing the lid and turning the member 4 into a position at right angles to the normal charging and discharging position, the piston may be withdrawn. In order to prevent loss of liquid, a valve 9 between the supply hopper 3 and the member 4 is first closed and the member rotated so as to discharge both measuring chambers through the normal outlet 10, this being made possible by an air bore (not shown), connecting the upper chamber to atmosphere in the closed position of the valve 9.

Title: Control system for elevators
Inventor: GINGRICH JOHN ALVIN
IPC: B66B1/16
Filed: 1964-07-29
Abstract: 1,094,760. Lift control systems. DOVER CORPORATION (CANADA) Ltd. March 5, 1965 [July 29, 1964], No. 30170/64. Heading B8L. [Also in Division H2] Slowing, stopping, and levelling of a lift is controlled by a system which uses selectively activated energy sources at each floor and a vertical line of receiving devices on the lift car. Preferred are electromagnets IPM . . . TPM which operate reed switches on a column 6, but inductive, light, radio and audio devices are mentioned. The call system is not described, but the arrangement is such that, when the car leaves a given floor a selector switch S (or logic circuit or the like) is stepped on to energize the electromagnet of the next floor; if the car is not required to stop at that next floor closure of its first reed switch (PCU or PCD, Fig. 4, not shown) causes S to step on so that the remaining reed switches are not actuated at the floor. At the required floor stepping of S is prevented so that each of the reed switches are actuated in turn, which causes slowing of the motor; the switches are closely and accurately spaced at the centre of the support 6 to effect final levelling. The switches are associated with a fully described relay system which allows the lift to stop in response to a late call, but only if it can do so with normal deceleration. If the selector S gets out of step with the car, the latter travels to the top or bottom floor and is stopped by limit switches while the selector steps round until its opposite arm becomes aligned. There may be separate columns 6 of reed switches for up and down travel, and a third one for levelling only. The lift motor HMA is Ward-Leonard controlled, the generator field GF being progressively varied by sequentially operated relay contacts shorting resistor R1, and for top speed a resistor R2 is inserted in the motor field HMF; there is an electro-mechanical brake BS. Acceleration is limited by dashpots on at least some of the relays which short R1; opening of the relays for deceleration is effected by the reed switches on the column 6 and the rate thus depends upon the speed of the car.

Filed: 1929-10-08
Abstract: 341,082. Valve amplifying and detecting circuits. ROBINSON, J., 76, Mill Way, Mill Hill, Middlesex. Oct. 8, 1929, No. 30532. [Classes 39 (i) and 40 (v).] A thermionic valve system in which self-oscillation is undesirable and which is, or may be adjusted to be, unstable is provided with means to introduce into the system energy of the same frequency and differing in phase from the energy in the system which are rendered operative when the energy in the system reaches a pre-determined value in order to prevent self-oscillation. Fig. 1 shows a receiver in which an auxiliary valve 19 is fed in phase opposition to the detector 10 and biassed so as to be inoperative, except when the energy of the system exceeds a pre-determined value, and on this value being exceeded, energy, to prevent self oscillation, is fed to the input circuit 11. Fig. 3 shows a valve of special construction in which the grid structure varies for the two anodes so that with normal working only one of the elements is effective while excess energy renders the other active and causes the application of reverse reaction. In one modification (Fig. 2 not shown) similar grids differently biased are employed, and in a further modification (Fig. 4 not shown) a single grid structure of resistance wire through which current flows is employed so as to produce different effective biasses for the two valve elements. Fig. 6 shows a modification in which the difference in the valve element characteristics is produced by different anode voltages. The limiting of the energy in the system may alternatively be effected by arranging the system so that with inputs in excess of the pre-determined amount grid current is established and opposes further increase.
