Title: Improvements in or relating to the production of creams having curative properties
IPC: A61K47/44
Filed: 1928-01-02
Abstract: 309,012. Weissbein, S. Jan. 2. 1928. Salves; emulsions, making.-A process for the manufacture of curative creams for external use by saponifying fats or fatty acids with alkali, insufficient for neutralisation, and in the presence of colloid protectors such as glycerine and a saponin and while saponification is proceeding, introducing into the mixture with stirring a concentrated solution of a healing salt together with a saponin until a cream-like mass is obtained. In an example 54 gms. of fat (or fatty acid) are partially saponified with 8 gms. KOH, 6 gms. of water, 10 ccs. of methyl or ethyl alcohol, and 0.01 gm. of, saponin on a water bath. Shortly before the end of the reaction there is stirred into the hot reaction mixture a heated solution of 40 gms. of " Oeynhausen " salt in 80 gms. water, admixed with 0.01 gm. of saponin and 10 gms. of glycerine. On stirring a creamy mass results which is spread out to cool. The " Osenhausen " salt is a mixture of sodium, potassium, and magnesium chlorides and sulphates, the sodium and chlorine ions predominating, together with small quantities of lithium, calcium, manganese, aluminium, iron phosphates. and arsenates. Common salt may be used instead of this mixture of salts.

The quantity per unit length of a compressible material leaving a continuous processing plant is maintained constant by adjustment of the density of the material being fed to the plant, either by adjusting the pressure of a roller or by applying a variable positive air pressure, the cross-section and feed rate being maintained constant. As shown, the material 11, in a channel 13 is compressed by a roller 22 whose position is controlled in accordance with signals from a radiation gauge 27, 28 which continuously measures the output of the plant. Following the roller a knife 14, rotating a fixed distance above the channel, removes excess material, which may be recirculated, while the corrected stream enters the processing device 19. In the alternative arrangement (Fig. 3, not shown) the material is compressed by air pressure, applied in a chamber through which the material passes, and controlled by the radiation gauge, the conveyer being perforated and passing over a space open to atmosphere.

[Class 40 (v)] In a valve circuit comprising at least two valves the voltage applied to the electrodes of one valve is controlled as a function of the voltage existing across a circuit member included in the anode circuit of the other valve only. The Figure shows a push pull pair of valves V1, V2 with self biassing resistances r1 r2 and additional equal resistances R1, R2 the voltage difference across which is utilized to equalize the anode currents in the two valves. As shown rectifiers D1, D2 decrease the bias of the valve taking the smaller current. If the rectifiers are reversed the bias of the valve taking the greater current is increased. The rectifiers may be replaced impedances in which case unbalance varies the bias of both the valves. The arrangement is also applicable to parallel operated valves.

Title: Improved means for deriving a direct from an alternating voltage
Inventor: THOMAS DAVID CALDWELL
IPC: G05D3/14
Filed: 1951-01-08
Abstract: 689,996. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 18, 1951 [Jan. 8, 1951], No. 519/51. Class 38 (iv). An alternating voltage developed across an impedance is converted into a proportional direct voltage by alternately earthing opposite ends of the impedance at the frequency of the alternating voltage, the ends of the impedance being connected to a point between which and earth the direct voltage is obtained. The earthing means may be commutator or other synchronous switches, but preferably comprise sets of diode valves. When the alternating voltage reverses in phase, the rectified direct voltage changes in sign. As shown, the alternating voltage (which may be modulated as indicated at B, Fig. 2, and reverses in phase as it passes through zero amplitude) is developed across the secondary coil 10 of an input transformer which is connected at its ends to earthing switches 12. Each of these comprises parallel pairs of series-connected diode valves. The series pairs have their junctions connected respectively to the ends of the impedance 10 and to earth. A reference voltage A, Fig. 2, is applied from a coil 17 in opposite directions to the sets of diodes, so that the sets are rendered conductive alternately, thus alternately earthing the ends of the input coil. These ends are connected through resistors 19, 20 at the junction of which is produced a rectified voltage C, Fig. 2, the direction of rectification being reversed as the input alternating current reverses in phase. The rectified voltage C is passed to an amplifier 21 with negative feed-back through a resistor 22, and is smoothed by a high-pass filter 14, 25 to provide an output voltage at 26 of the form shown at D, Fig. 2. The demodulator may be used in remote control systems in which the input A.C. is an error voltage indicative by its amplitude and phase of the angular positional misalignment of dynamo-electric machines coupled to the controlling and controlled devices. Another use of the demodulator is in systems in which the angular position # of a shaft is denoted by two A.C. outputs proportional in amplitude to sin # and cos #, and reversing in phase when these functions change their sign.

The electrode device 10 includes a circular, flexible antiresilient sheet 12 of a framed plastic such as polyvinyl-chloride, sandwiched between cup members 14 and 16, the member 14 being made of a thermoplastics material. The electrode device 10 is held together by a stainless steel snap fastener 18 which includes a circular plate 20 from the centre of which a hollow stud 22 projects through apertures in the sheet 12 and the members 14, 16, and a lower plate 24 having a socket portion 26 receiving the stud 22. The upper surface of the sheet 12 has an acrylic pressure sensitive adhesive coating 28 which is protected, prior to use, by a paper sheet 30. A disc 32 of non-conducting spongy material forms a matrix for the electrolyte and is seated in the cup member 14. The matrix 32 may be formed from an open cell polyurethane. A plastics protective cover 38, having an annular portion 40 and a raised centre 42, fits over the cup member 14. The height of the cover 38 is greater than the height of the matrix 32 in the cup member 14 so that the inner surface 44 of the portion 42 is spaced from the matrix 32. A conical depression 46 holds the matrix 32 firmly against the cup member 14 until the electrode device 10 is ready for use, after the cover 38 and the paper sheet 30 have been removed. The alkali metal electrolyte is a sulphate consisting of between 1% by weight and a nearly saturated aqueous solution of the salt, and is made viscous by adding about 0.2% to about 8% by weight of a neutralised water soluble mucilage. Less than about 1% by weight of a mould inhibitor may be added. Several mucilages, neutralises and mould inhibitors are listed as being suitable but in three examples carboxypolymethane, triethanolamine and 2-chloro-m-xylenol are used as the mucilage, neutraliser and mould inhibitor respectively.

Abstract: 268,886. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Jan. 9, 1926. Sole-levelling.- To produce a " close edge," i.e., minimum crease between the welt or sole and upper after inseaming, a piece of flexible material is applied to the bottom of the shoe, and a machine, preferably of the roll type, is caused to apply compacting pressure to the shoe bottom by action on the flexible material. The shoe is placed on the jack and a saddle 22 of Indiantanned, " Zug," or " Beva " leather placed over it. The saddle is connected to the jacking lever 28 by springs 24, 26 on each side. To give a longitudinally concave shape to the saddle, its forward portion is slit at each side and a short piece removed from the middle of the strap so formed. Preferably, the slit is curved to form an ear to which the spring 26 is attached. The usual action of the roll 72 then flattens down the inseam and renders a filler unnecessary.
