Title: Soap pad
IPC: A47L13/17
Filed: 1962-02-08
Abstract: 946,634. Soap impregnated scouring pads. BRILLO MANUFACTING CO. Inc. Feb. 8, 1962 [Feb. 9, 1961], No. 4846/62. Headings A4F and A4R. In a scouring pad a flexible backing sheet 10 has secured to it, e.g. by adhesive, a layer of mineral or metal wool 11 shaped in a pattern of alternate raised 25 and depressed 27 areas and impregnated with a solid soap, -the bulk of which is held within the raised areas to serve as reservoirs dissolved progressively as the wool is worn away in use. The backing sheet may comprise high wet strength paper or synthetic plastic coated if desired on the working (abrasive) side with detergent (of different type to the soap) and/or a material resisting moisture penetration, and creped or corrugated as at 10a on the finger side for improved gripping. The metal e.g. steel, wool, may be corrugated, Fig. 1, or comprise individual projections (Fig. 2, not shown), the shaping being effected before or after securing it to the backing sheet. The pad may have a marginal compressed band 20 and decorative rib 21, and be provided with a finger loop and/or tab. A means of filling the wool with liquid soap which subsequently solidifies is described.

Title: A ring filter circuit
IPC: H03H7/48
Filed: 1954-02-19
Abstract: 746,890. Filter circuits. STANDARD TELEPHONES & CABLES, Ltd. Feb. 19, 1954 [Feb. 28, 1953], No. 4964/54. Class 40 (8). [Also in Group XL (c)] A circuit for connecting one or more generators to two or more loads comprises a ring of transmission line or wave-guide of circumference k# (k= 1, 2, 3 ... ), the spaces between adjacent terminals being m#/4 (m = 0, 1, 2, 3 ...), the path length difference between mutually decoupled terminals being #/2 (2n+1) n = 0, 1, 2, 3 ... ), the ring sectors being equally loaded. The circumference of the ring of Fig. 1 is 2# and the two generators S1, S2 are arranged so that the path difference between the two directions around the ring is #/2. The useful.load R A  and the balance impedance R B  are decoupled in a similar manner as are the two equal control impedances R. The magnitude and frequency response of the control impedances are made equal and are such that the energy from the generators, which may be the sound and picture transmitters of a television station, are divided in desired proportion and with a desired frequency dependency to the two loads, one of which may be an antenna. The circuit can be used to suppress the lower sideband of the picture frequency spectrum. When it is desired to distribute energy from one transmitter to two loads, the connection for S2 and the wavelength section between R and R A  become superfluous. The result is the circuit of Fig. 5 of circumference equal to #. The control reactances are equal and are ganged together so that they may be varied equally. Since the proportion of the energy distributed to either R A  or R B  depends upon the value of R this energy may be amplitude or pulse modulated by mechanical or electronic control of R. Circuits of the type shown in Figs. 1 and 5 may be connected together as shown in Fig. 6. The circuits II, III, IV which are of the type shown in Fig. 5, may have overlapping attenuation maxima and together may constitute a lowersideband rejection filter. The circuit I which is of the type shown in Fig. 1 may be designed to reject the sound.

Abstract: A hypohalogenated rubber derivative is obtained by dispersing a synthetic rubber in an organic solvent, and reacting the dispersion separately with 0.45 to 1.0 mol. of a hypohalous acid in aqueous solution at a pH of 4 to 9 for each 100 grams of rubber, and with 1.3 X 10-2 to 5.4 X 10-2 mol. of a metal salt of a hypohalous acid in aqueous solution at a pH of 9-14 for each 100 grams of rubber.  The rubber may be a polymer of butadiene-1,3, isoprene, chloroprene, 2,3-dimethyl butadiene-1,3 or a copolymer of these monomers with acrylonitrile, styrene, methyl acrylate, methyl methacrylate, methacrylonitrile and isobutylene.  The rubber may be dissolved in xylene, toluene, hexane, heptane, benzene, carbon tetrachloride, chloroform, ethylene dichloride, mono-, di- and tri-chloroethenes, or dipentenes, optionally with small quantities of gasoline or butyl acetate.

Title: Improvements in superconductive components
IPC: G11C11/44
Filed: 1960-02-15
Abstract: 941427 Super-conductors INTERNATIONAL BUSINESS MACHINES CORPORATION 15 Feb 1960 [20 May 1959] 5258/60 Headings H1A A5 and A4D A super-conductor circuit component consists of an alloy of indium and mercury. The Specification explains that super-conductive alloys often show transitions from the super-conductive to the resistive state which are not sharp due to inhomogeneity of the material, each microscopic portion having its individual critical temperature. Fig. 2 however, shows the critical temperature of an indium mercury alloy plotted against atomic percentage of mercury and indicates that in the range 0À05-2% mercury the critical temperature is both a minimum and is constant. Fig. 3 shows the variation in the width of the transition curves in K. plotted against atomic percentage of mercury and shows that this minimum width corresponds to minimum slope in curve 2. Such an alloy may be manufactured by reducing the super-conductive materials to liquid form and mixing them in a vacuum to form a homogeneous solution. The alloy is then subjected to violent agitation for 15 minutes at 175C. The liquid solution is then quenched in an oil bath and extruded through a die to the desired shape. The alloy was then subjected to a temperature of nine-tenths of its melting temperature for a few hundred hours. Fig. 5 shows a bi-stable circuit comprising four super-conductive circuits K30-K33 each comprising a super-conductive gate and a superconductive control winding. Current flows from source 34 through one of a pair of parallel paths to terminal 37. One path includes gate 35 of K30 and control conductor 36 of K32, the other gate 38 of K31 and control conductor 39 of K33. One path or the other is rendered resistive by current flow through control conductor 40 or 41 or K30 and K31 and current flows to terminal 44 or 45 according as current from source 34 is in one path or the other. Specification 862, 178 is referred to.

Patent GB-420507-A (GB)
Title: Method of and means for concentrating volatile fatty acids
IPC: C07C51/487
Filed: 1933-02-27
Abstract: <PICT:0420507/IV/1> Volatile aliphatic acids such as acetic acid are recovered from dilute solutions by adding an aliphatic amine or an amine in which the amino group is in an aliphatic side-chain of an aromatic ring, of boiling-point above 130 DEG  C., and distilling off the water, the amine salt being finally decomposed by more strongly heating to recover the acid.  Suitable amines are triethanolamine and its homologues, morpholins and oxyethyl morpholins and their homologues.  Alternatively, the vapour of the dilute acid may be passed into the amine at about 105 DEG  C.  The last portions of water are preferably removed by passing through the liquid the vapour of benzene, toluene, xylene, "benzenes of suitable boiling-points" or halogenated hydrocarbons such as chloroform and carbon tetrachloride, the removal of the water being thus effected without decomposition of the amine salt.  In an example, dilute acetic acid in a tank 1, which has been preheated in a heater 28 receives an addition of the equivalent quantity of triethanolamine and the mixture is passed by a pipe 2 to a distillation column 4 heated by a coil 6, the evolved steam being condensed in a cooler 7.  The concentrated liquor, of boiling-point 105--107 DEG  C., is drawn off at 8 and passes by a pipe 9 to a dehydration column 10 to which benzene vapour is admitted at 12.  The benzene-steam mixture passes off to a cooler 13 and the condensate separates into layers in a tank 14, the benzene layer being vaporized at 17 and returned to the column 10.  The dehydrated amine salt passes out at 18 to a column 20 in which a vacuum is maintained, and which is heated to 150 DEG  C. to liberate the acetic acid.  The amine leaving the column 20 passes to the heater 28 and heats the dilute acetic acid and then goes through a mixing chamber 31 to the tank 1.  Alternatively, the dehydration of the amine salt may be effected in a vacuum at 30--50 DEG  C., and in this case the proportions may be such that an acid amine salt containing 3 molecules of monobasic amine to 2 molecules of monobasic acid is produced.  The liberation of the acid is effected as before by more strongly heating the amine salt in a vacuum.
