Title: Improvements in or relating to toilet creams having cleansing properties
IPC: A61Q19/10
Filed: 1940-12-16
Abstract: 548,382. Saponaceous cleansing compositions ; toilet creams. McCORMICK, J. E. Dec. 16, 1940, No. 17739. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 14, 1941.] [Class 91] [Also in Group VI] A toilet cream having cleansing properties comprises an emulsified mixture of milk, an amine soap, and a fatty oil, hydrogenated or not, with either buttermilk powder or a glycol, the latter two ingredients being present in an amount less than the amine soap. A preservative or a perfume may optionally be added. The milk comprises at least 80 per cent of the composition. Milk of pH 6.85 is specified, the pH being adjusted by a suitable buffer, such as magnesium hydroxide. The amine soaps may be those obtained from any soap-forming fatty acid, stearic acid, palmitic acid, oleic acid, iso-oleic acid and peanut fatty acid being specified, and an amine, triethanolamine, monoethanolamine, diethamolamine, and iso-propylolamine being specified. The fatty oil is preferably a hydrogenated oil and may be hydrogenated castor oil, coconut oil, palm kernel oil or olive oil, but any hydrogenated oil of high saponification value may be used. The preservatives speciled comprise boric acid. borates, normal butyl parahydroxybenzoate, and ethyl silicate. When the mixtures contain a glycol, a lower alkylene glycol is used such as propylene glycol. In the preparation of a composition containing milk, amine soap, hydrogenated oil, preservative. buttermilk powder, and a perfume oil, a base composition of the soap and oil is first prepared and the heated liquid then added to the milk and preservative at 190‹F. After agitation and lowering the temperature to 150‹F., the buttermilk powder and perfume oil are added. The mixture is then cooled and passed through a colloid mill to obtain the toilet cream as a jellylike emulsion. In the preparation of a composition containing milk, amine soap, hydrogenated oil, preservative, alkylene glycol, and a perfume oil, two base compositions are prepared, one containing amine soap, glycol and the preservative, and the other containing amine soap with the fatty acid in excess, the hydrogenated oil, glycol and the perfume oil. The first base composition is heated to 190‹F. so as to dissolve the preservative and is then cooled to room temperature, when it hardens. In the second base composition, the oil is added at 140‹F. and then the glycol at 130‹F., the mixture being then cooled as before. The final composition is then prepared by dissolving the first base composition in the milk heated to 170‹F. and then adding the second base composition after the temperature of the solution has been reduced to 150‹F., the agitated mass is then cooled. The oil-containing base composition forms an emulsion with the milk and first base composition, the excess of fatty acid in the former stabilizing the product.

IPC: A42B7/00
Filed: 1917-12-07
Abstract: 114,598. Gardner, A. C. Dec. 7, 1917. Hats, securing to head.-In the device for securing hats to the head as described in Specification 2079/11, wherein curved pins are driven into or withdrawn from the hair by depressing or lifting an external knob connected to a vertical rod passing through the top of the hat, a safety device is provided which prevents the pins from being withdrawn too far, and an adapter renders the same device suitable for hats of varying height. The bell-mouthed guide b having side or bottom perforations for the hat pins a, is connected to a plate e secured to the top of the hat, and the rod d secured to the disk c carrying the pins is attached to a knob f, the extension f<1> of which acts as a catch when it is forced into the split socket e<1>. The diaphragm, forming the principal feature of the invention to regulate the amount to which the pins may be withdrawn, is shown at g. The lower plate of the bell has a central perforation h' which is intended to receive the projection j on any one of a series of adapters h of varying height, whereby the device is suited for hats of differing depths. In the modification shown in Fig. 4, inclined legs k are used instead of the guide b, and these carry at their lower ends U-shaped adapters h<2>, which are simply pushed into or drawn out of the legs to the desired extent to adjust the device to hats of varying heights. The lower ends of the legs are bent as shown to act as guides for the pins a. The diaphragm of the former form is replaced by a wire frame g.

Title: Improvements in or relating to magnetic shift registers
IPC: G11C19/04
Filed: 1958-06-06
Abstract: 884,014. Shift registers. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 6, 1958 [June 8, 1957], No. 18143/58. Class 106 (1). A shift register comprises a number of magnetic cores successively coupled together and having windings connected in series, the connecting points of the windings being alternately connected through resistor-bridged rectifiers to a first terminal and a second terminal of a source of A.C. As shown, the cores K1-K6 of a shift register have windings L1-L6 connected in series, the connecting points of the windings being connected alternately, each through a rectifier bridged by a resistor, such as G2, R2, to opposite terminals of an A.C. source GR. As shown, " 1 " 's are entered by pulsing input winding LE on core K1, and output pulses are obtained from winding LU on core K6. When line A2 is relatively posi. tive, the pairs of windings L1, L2 ; L3, L4 and L5, L6 are associated through rectifiers G1, G3, G5, G7 and common resistors R2, R4 and R6, and the arrangement is such that only if the cores for the left-hand and right-hand windings of a pair, e.g. cores K1 and K2, are in the " 1 " and " 0 " state respectively, both windings present a high impedance to the pulse from A2 and both cores are changed over. Similarly, when line A1 is relatively positive, the pairs of windings L2, L3 and L4, L5 are associated. Thus, in response to a single cycle of A.C., any stored " 1 " is shifted two cores along.

Title: Improvements in or relating to elevator control systems
IPC: B66B1/18
Filed: 1943-11-03
Abstract: 568,839. Lift control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 3, 1943, No. 18212. Convention date, Nov. 4, 1942. [Class 40 (i)] In a multi-car system in which up-and-down floor switches 2UJ ... 4UJ, 2DJ ... 4DJ control marking circuits which serve to stop the first car approaching the floor and travelling in the appropriate direction, the operation of a car switch 2C ... 4C to stop a car at a desired floor causes the corresponding marking circuit to be disabled. If, for example, an up call is registered at the 4th floor, and a car is started from the lower terminal to carry passengers to the same floor, the call is answered by that car even though another car may approach the 4th floor ahead of it. For this purpose, the car switches control a common set of selecting relays 2UA ... 4UA, 2DA ... 4DA which when operated disable the corresponding marking circuits 2US ... 4US, 2DS ... 4DS. These circuits are controlled in the usual way by the floor switches and serve to apply potential to corresponding contacts of the floor selectors of all the cars. The stoppage of the cars is brought about by the action of induction plates in the customary manner and a slowrelease holding relay TE prevents the restarting of a car immediately after it has stopped at a floor.

Abstract: 727,164. Electric weighing machines. SCRIBBANS-KEMP, Ltd., and HENDON, A. L. Oct. 21, 1953 [July 23, 1952], No. 18606/52. Class 40 (1). The output signal of an electric weighing- machine determining the weight of the contents of a container is fed through an R.C. circuit of adjustable time constant so that the time constant is short, giving zero output voltage, until filling commences when the time constant is made long, to give a signal proportional to the contents only. As shown (Fig. 3) the arrival of an empty container on weighing-machine 1 produces a pulse in a-photo-cell 8 to trigger flip-flop circuit 9, whereupon a relay R operates to close a contact r short-circuiting a resistor R1 in the R.C. circuit, so that the time constant is reduced and the output voltage of the R.C. circuit is reduced to zero. The flip-flop circuit 9 restores to normal and releases relay R in time for a weight signal from the machine 1 proportional to the filling only to be fed through the R.C. circuit to indicating or control circuits. The signal from the weighing-machine 1 is fed to the R.C. circuit through a Selsyn transmitter 2 and receiver 4. Specification 664,063 is referred to.

A bonded non-woven fabric is made of synthetic, organic, thermoplastic, staple fibres produced from melt-spun filaments, and has intermittent light- and dark-coloured areas; the thermoplastic fibres in the dark-coloured areas are bonded together and to at least some of the fibres in the light-coloured areas, but the majority of the fibres in the light-coloured areas are unbonded. -The fabric may be made by blending dark- and light-coloured fibres, forming them into a web, exposing the web to radiant heat so that the fibres in the darkcoloured areas melt preferentially, and then cooling the web to solidify them. Alternatively, fibres all of the same colour may be formed into a web, which is then printed with a pattern of light and dark areas and exposed to radiant heat. The synthetic fibres may be of polypropylene, polyethylene, poly(4-methylpentene- 1), polyamides, poly-(ethylene terephthalate), acrylic polymers, poly(vinyl chloride), poly (vinylidene chloride) or poly(vinyl acetate), and may be molecularly oriented by drawing, and crimped. The fabric may be wholly or synthetic fibres, or may be of a blend of natural and synthetic fibres. The webs may be random or oriented, and may be made by a wet or a dry process, e.g. carding.

Title: Means for and method for regulating transmission over electric circuits
IPC: H02J1/08
Filed: 1920-07-06
Abstract: 146,879. Western Electric Co., (Assignees of Clark, A. B.). Sept. 10, 1918, [Convention date]. Telephonic relays, repeaters, and translators.-Transmission circuits subject to variable conditions of temperature &c. are automatically compensated by a pilot line containing means responsive to the said variable conditions and acting to adjust the elements of the transmission circuits. In the arrangement shown two two-wire transmission circuits L3, L, are compensated by a pilot line L5 which is made up in the same cable. The line L5 forms one arm of a wheatstone bridge of which resistances R1, R2, R5 form the other arms, their values being proportioned so that under average conditions the bridge is in a state of balance. If the resistance of L5 changes the balance is disturbed, a current flows along the neutral wire through a polarized relay 3, and sets in action a vibratory interrupter 10 and one of two step-by-step magnets 4, 5 whereby a wiper contact S1 is moved over a divided resistance R6 to restore the balance of the bridge. The automatic movement thus produced is proportional in magnitude and direction to the change of resistance in L5. The moving arm S1 is attached to another switch element S composed of two wiping contacts S3, S4 traversing potentiometers P3, P4, which respectively control amplifiers A3, A4 in the circuits L3, L4. An automatic adjustment of the amplification in each line is thus obtained.
