Filed: 1934-01-25
Abstract: 427,914. Perforated sheet rubber; vulcanising-moulds. GRABEC, J., 29, Spitalska, and LEDOFSKY, A., 26, Penenska, both in BrÓtislava, Czecho-Slovakia. Jan. 25, 1934, No. 2653. Convention date, May 26, 1933. [Classes 70 and 87 (ii)] [See also Groups VI and VII] Flexible, extensible, perforated sheet rubber for making bandages, knee - caps, stockings, corsets, shoe - uppers, bathing - dresses, &c. has the perforations arranged to form intersecting webs, the perforations, which number at least 16 per square centimetre and preferably 50-150, being formed by displacing the rubber by a pressing or shaping process before completion of solidification. The perforations may be tapered and their combined superficial area may amount, on one side or on both, to at least half the total superficial area of the material. The thickness of the material may vary between 0À2 mm. and 2 mm. A device for making it consists of a die a of hard material, preferably steel, and a die b having an insertion g of relatively soft material, e.g. lead. The die a comprises upstanding pins f arranged in rows and having pointed ends which fit into recesses in the portion g. When a non-vulcanized or incompletely-vulcanized rubber sheet is placed between the two dies and the latter are pressed together, the pins pierce the sheet and the displaced rubber fills out the recesses d, e. The dies may be heated so that vulcanization proceeds with perforating. Specifications 353,656 and 355,311 are referred to.

Patent GB-746615-A (GB)
Title: Process for producing chlorine dioxide and for disinfecting and purifying water
IPC: C02F1/76
Filed: 1954-01-29
Abstract: Chlorine dioxide is produced by reacting a chlorite or chlorous acid with ozone in the presence of water.  Chlorites may be sodium, potassium, magnesium, calcium, ammonium, or aluminium chlorites.  The reaction may be effected by adding ozone-containing water to, or introducing ozone-containing gases into aqueous solutions or suspensions of chlorites or chlorous acid.  Thus, a solution of 50-150 parts sodium chlorite in 200 parts water flows down a tower at not more than 30 DEG C., e.g. 15-25 DEG C., countercurrent to ozonized air.  Alternatively, a paste, prepared by mixing a chlorite or chlorous acid, water, and an inert solid carrier, e.g. asbestos kieselguhr, silica gel, earthenware, aluminium oxide or sand, may be spread in thin layers on stoneware plates, and treated with ozonized air at not more than 28 DEG C.  The reaction may be used in the disinfecting and purifying of water (see Groups I, VI).ALSO:The preparation of chlorine dioxide by reacting a chlorite or chlorous acid with ozone in the presence of water (see Group III) is applied to the disinfecting and purifying of water.  Thus, water, which is being subjected, while flowing down a tower, to a countercurrent of ozonized air, e.g. 1-3 per cent ozone, has continuously added thereto a dilute or concentrated solution of a chlorite, e.g. sodium chlorite 0.05-5 per cent solution.  The ozone destroys organic material and nitrite, and precipitates iron and manganese as oxides in the lower part of the tower. Unabsorbed ozone reacts in the upper part of the tower with the chlorite, which should be in amount stoichiometrically equivalent to the unabsorbed ozone so that no chlorite remains, to form chlorine dioxide.  Alternatively, chlorine dioxide may be produced in a minor stream of water, e.g. ground or well water, by adding chlorite solution thereto and reacting with ozone, and the resulting chlorine dioxide-containing stream added to the bulk of the water, e.g. surface water.ALSO:The preparation of chlorine dioxide by reacting a chlorite or chlorous acid with ozone in the presence of water (see Group III) is applied to the disinfecting and purifying of water.

Title: Electrical bridge network
Inventor: DAVIS VINCENT C
IPC: G01R17/10
Filed: 1950-02-03
Abstract: 685,220. Temperature responsive resistance networks. CALIFORNIA RESEARCH CORPORATION. Feb. 3, 1950, No. 2856/50. Class 40 (i). In a temperature responsive resistance network thermistors R3, R5, R7 ... Rn positioned at different locations are paired respectively in series with temperature maximum setting rheostats R4, R6, R8 ... Rn and if the meter M associated with rectifiers Zl, Z2, Z3 ... Zn through closed switch contacts T/T1 is actuated it will be because the temperature has gone above the pre-set maximum at one or more of the thermistor locations. If, for example, the temperature at the location of R3 exceeds the value corresponding to the setting on R4 there will be a reversal of the polarity of the junction Y of R3/R4 with respect to the junction X of fixed series connected registers R1/R2 whereby meter M in series with rectifier ZI across X, Y is actuated consequent upon the polarity reversal unblocking the rectifier Z1. To identify the location responsible for a deflection on M the switch contact T is sequentially connected to contacts T2, T3, T4 ... Tn thus isolating the rectifiers and connecting M directly across X, Y, &c. If M is calibrated in temperature units any deflection thereon with T/T1, closed will correspond to the highest temperature imposed on thermistors R3, R5, &c. If with no deflection on M it is required to know the highest temperature this knowledge may be obtained by adjusting the rheostats R4, R6, &c., to their original balancing or zero setting positions so that the deflection on M then produced will show the highest temperature. Should the system be such that any change of temperature is in one direction only A.C. may be employed to energize the network with M shunted by a large capacitance. A compensating rectifier is added in series with M Fig. 5 (not shown) if dependently on the number of rectifiers employed, Z1, &c. and their back-to-front resistance there would otherwise occur an interference reverse current flow through M. The fixed series-connected resistances R1/R2 may be replaced by batteries.
