Title: Analog to digital converter
IPC: H03M1/00
Filed: 1969-03-24
Abstract: 1,203,551. Dual ramp digital voltmeters. INTERNATIONAL BUSINESS MACHINES CORP. 24 March, 1969 [25 March, 1968], No. 15259/69. Heading G4H. In a dual-ramp digital voltmeter, the time interval over which the unknown analogue voltage is integrated is varied in accordance with the range in which the analogue signal lies. In the embodiment of Fig. 1 the gain factor for the analogue signal is stored in register 24 and during integration of the input its contents are compared with the count in counter 38 receiving overflow pulses from counter 16 until equality occurs when a reference signal 12 of opposite polarity to the input is applied to discharge the integrator, counter 16 counting clock pulses until the integrator output reaches datum level. In a modification (Fig. 2, not shown) the integrator is discharged by two reference signals, as described in Specification 1,261,549, the first (V R1 ) being applied at the end of integration until the output of the integrator falls to a first level (V t ) and the second (VR 2 ) being applied from this time until the integrator output reaches the datum level. In a modification the complement of the gain is stored in a counter stepped up by the full count pulses from the counter 16 or alternatively the gain may be stored in a counter which is stepped down by the overflow pulses. The range of the output signal may be determined by comparing the integrator output with a reference signal V t  (Fig. 7), the time interval over which the integration occurs being determined by the time of arrival of a signal from comparator 72. Counter 70 receiving the overflow pulses from counter 92 is read out by the comparator output signal 78 to give an indication of the range of the input, the time and integration being determined by the enabled lead of a decoder 74 decoding the contents of overflow counter 70 when the signal 78 arrives.

Abstract: 1,189,353. Transit-time tubes. ENGLISH ELECTRIC VALVE CO. Ltd. 29 March, 1968 [4 April, 1967], No. 15264/67. Heading H1D. A crossed-field discharge device includes an annular cathode spaced from an annular anode to form an interaction space which is symmetrical about an axis, the electric field being inclined to that axis at an angle other than 0 degrees and other than 90 degrees when the device is operating. As shown, a magnetron includes an annular cavity 11 in a magnet 10, having a cathode 7 the emissive surface 8 of which is disposed opposite and parallel to the ends of the #/4 long fingers 2 of a slow wave structure supported from an annular waveguide cavity 5. The interaction space is symmetrical about the axis 3, and the walls of the magnet cavity, and the emissive surface of the cathode and the ends of the fingers 2 are shaped, as shown, to ensure that the electric and magnetic fields are mutually perpendicular, with the electric field directed at an angle α to the axis 3. Operation in the # mode is ensured by the provision of slots 6 between every other cavity of the slow wave structure and the fast wave waveguide cavity 5, asymmetry in the size, shape, position or orientation of the slots permitting excitation of only a forward or only a backward wave in the cavity 5, which is coupled to the waveguide 12 by a directional coupler 13. With tight coupling between the slow wave structure and the cavity 5, the device may be tuned either by the introduction into the cavity of a dielectric cylinder, or by forming cavity 5 from ridged waveguide and deforming the wall to which the ridge is attached.

Title: Improvements in suction cleaners
IPC: A47L9/00
Filed: 1963-04-18
Abstract: 956,764. Suction cleaners. LICENTIA PATENT-VERWALTUNGS G.m.b.H. April 18, 1963 [April 24, 1962], No. 15351/63. Heading A4F. In a suction cleaner of the kind having a built-in fan operated by an electromotor and a dust bag arranged in the interior of the apparatus casing, a manually adjustable valve for regulating the suction also acts as an automatic safety valve for the delivery of by-pass cooling air to the fan motor. The valve operating knob 4 is turned manually to rotate the valve plate 6 in contact with the curved wall 1 of the apparatus casing to open the valve to the desired extent to allow air into the apparatus casing to reduce the suction. Should the flow of cooling air for the fan motor be reduced when the valve is closed, e.g. due to an obstruction in the air duct or to the filling of the dust bag, the resulting increased suction at the fan inlet side will draw the plate 6 downwardly against the action of a spring 7 to open the valve.

Abstract: 1,224,702. Film casting rollers. NIPPON RAYON K.K. 24 March, 1969 [22 March, 1968], No. 15367/69. Headings B5A and B5B. A polymer melt is extruded from a die 2 in the form of a continuous film 1 and cast on, and drawn from, the cooling roller 3. To remove deposits from the roller water or alcohol is sprayed on to the roller through spray pipe 5. Falling liquid encounters the nip formed between roller 3 and a roller 9, and is transported over the turning roller 9 to fall from the ends of the nip formed with a second roller 9. Liquid rising above the spray device encounters the nip between nitrile-rubber roller 6 and roller 3, which causes the liquid to fall back to the rollers 9. Alternatively the rising liquid may be removed by a block of foam (not shown), having a suction pipe embedded in it to remove the absorbed water. The roller 3 is finally dried by hot air drier 7. The contact pressure of the roller 6, or of the alternative sponge, bearing on the roller 3 may be adjusted. The use of the apparatus is exemplified in the production of polyamide films.

Title: Improvements in the preparation of stable suspensions of animal tissue cells
IPC: A61K35/12
Filed: 1934-05-24
Abstract: Non - agglutinating or non - agglutinable aqueous suspensions of animal tissue cells are prepared by dispersing fresh cellular material in the presence of small amounts of alcohols containing more than six carbon atoms, e.g. octyl alcohol or benzyl alcohol; organic compounds containing sulphonic groups, or water-soluble salts thereof, e.g. polyanethol sulphonic acid salts, or m - amino - benzoyl - m - amino - p - methyl - benzoyl - 1 - naphthylamine - 4 - 6 - 8 trisulphonic acid carbamide; or the organ extracts known under the names Heparin, Hirudin and Novirudin.  These substances do not affect the cells and are either surface-tension depressants or prevent the coagulation of blood.  Antiseptic agents are also preferably added to the suspension, e.g. in amounts of the order of 0,1 to 0,2 per cent.  Suitable agents include camphoric acid, hexamethylene tetramine, hexamethylene tetramine triborate, anhydromethylene citric acid hexamethylene tetramine, salicylic acid phenyl ester, hexyl resorcin, and the methyl and ethyl esters of hydroxybenzoic acid.  The above substances may also be injected before the cell suspensions are prepared.  Such suspensions, e.g. of embryonal cells, cells of normal or diseased organs, or cancer cells may be treated for test purposes with sera, other cells, chemical reagents, ferments or hormones and the results observed by suitable methods.  According to examples: (1) a mixture of 0,25 c.c. secondary octyl alcohol, 0,75 c.c. absolute ethyl alcohol and 0,6 c.c. water is added to an agglutinated cell suspension in the proportion of 1 drop per c.c. of suspension.  After shaking, the agglomerations are broken up into single cells; (2) one drop of 1 per cent solution of Hirudin is added per c.c. of a cell suspension.  The cells remain singly in the suspension; (3) similarly one drop of 0,1 per cent aqueous solution of m-amino-benzoyl-m-amino - p - methyl - benzoyl - 1 - naphthylamine - 4-6-8-trisulphonic acid carbamide is added to each c.c. of a cell suspension; (4) a rabbit having a tumour is injected intravenously with 15 mgs. of the sodium salt of polyanethol sulphonic acid per kgm. living weight.  The tumour mass is isolated from the dead animal and worked up into a cell suspension which has little tendency to agglutinate.

Title: Improvements in the anti-crease treatment of cellulosic fabrics
IPC: D06M11/79
Filed: 1935-05-29
Abstract: Cellulosic fabrics are rendered crease-resistant by forming or depositing substantially within the structure of the cellulose a metallic compound in a vitreous or transparent or semi-transparent form in a state of continuity, other than a resin.  Preferred metallic compounds are metallic salts of silicic acid, boro-silicic acid, boric acid or phosphoric acid; as assistants to the retention of the vitreous state may be added glycol, glycerine or other polyhydric alcohol, or lactic, tartaric, citric, or other hydroxy acid, also formic or acetic acid.  The fabric may be dried and heated to 150 DEG  C.  Any sizing or stiffening agent must first be removed from the fabric.  In examples: (1) a cellulosic fabric, e.g. of rayon, is freed from any sizing material and impregnated with a 5--10 per cent solution of sodium silicate containing \ba1/2\be--1 per cent of glycerine, squeezed and dried in hot air.  The fabric is then passed over heated rollers or plates at 100--150 DEG  C.; (2) a solution of borax, caustic soda and sodium silicate is added with stirring to a hot solution of zinc acetate, to precipitate a boro-silicate of zinc. The precipitate is washed and dissolved in 5 per cent acetic acid containing \ba1/2\be--1 per cent of glycerine or glucose to form a solution containing 10--15 per cent of solids.  A cellulosic fabric is impregnated in this solution, squeezed, dried, and heated as before; (3) as in example 2, except that the glycerine or glucose is replaced by a salt of lactic or citric acid.  U.S.A. Specification 1,734,516 is referred to.
