Patent GB-1035347-A (GB)
Title: Improvements in or relating to hair coloring compositions and methods for producing same
Inventor: AUSTIN WILLIAM EPHRAIM
Filed: 1963-04-25
Abstract: Hair is dyed with an aqueous composition containing a water-insoluble dye dispersed therein and, as dispersing agent, a mixture of polyoxyethylene ether of a C10 to C30 fatty alcohol and a C10 to C30 fatty alcohol-urea adduct.  The dyestuff may be a disperse or a solvent dye or may be a water-insoluble complex of a cationic dye with an anionic surfactant; many dyestuffs are specified.  The prefered polyoxyethylene ethers are derived from oleyl, stearyl and lauryl alcohols adding sufficient ethylene oxide to each mol of alcohol to obtain the desired hydrophilic-lipophilic balance.  The urea-fatty alcohol adducts may be derived from lauryl, cetyl, myristyl or stearyl alcohols and may be added to the compositions as such or formed in situ.  The compositions may be prepared by stirring the components into the liquified polyoxyethylene ether at 50-60 DEG C. and continuing to stir while cooling to room temperature.  The cationic dye/anionic dispersant may also be added as such or formed in situ.  The composition may be applied to semi-dry shampooed hair by known methods to give semi-permanent colouration.  Examples are given.

Abstract: 400,554. Sewing-machines. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. June 9, 1933, No. 16533. Convention date, June 25, 1932. [Class 112.] The motor controller of an electricallv driven machine is operated by a horizontally sliding bar operated in turn by a knee lever which can be swung up into inoperative position, but which swings down to an operative position in which it is at an acute angle with the bar. A plate 9 is screwed to the front wall 6 of the table and carries a rheostat 10 of the carbon compression type operated by a draw-bar 11 in the usual way for increasing or diminishing the resistance. The spring 13 raises the draw-bar to its " off " position when the pull is relieved. The lower end of the draw-bar carries a nut 14 engaged by the lever 15 fulcrumed on a screw 16. A lug 17 of the lever 15 enters a notch 17<1> in the flange of the nut to prevent accidental turning. The lever 15 is reinforced at its lower end by a wear-strip 19 of hardened steel. The sliding bar is in two sections 23, 24, adjustably clamped together and sliding in a guide trough 22. The section 23 carries the hinged knee lever 34, the stop 35 limiting the swing and enabling the operator to slide the plate by pressure. The section 24 has ears supporting the pin 37 which carries three antifriction rollers 38, 39, 40, the centre one of which effects the tilting of the lever 15 to operate the draw-bar of the rheostat.

The heat required for an endothermic reaction to take place between a first fluid, e.g. fuel, introduced in pulses through conduit 1 to a reaction vessel 2 and a second fluid, e.g. water vapour, injected also in pulses at 4 into alternate pulse cuts of the first fluid is obtained from an exothermic reaction which takes place between the first fluid and a third fluid, e.g. air, also injected in pulses at 3 into the other set of alternate pulse cuts of the first fluid. The reactions are initiated in vessel 2 and continue in a conduit 5 which has a large wall surface through which heat is exchanged. After completion of the reactions the fluid is cooled in heat exchangers 6 and 7, which are used for heating the air and for producing the water vapour, and then passed to a washing tower 8 before separated at 9 by valves into the distinct pulse cuts 10 and 11 of the fluid.

Title: Improvements in or relating to data processing apparatus
IPC: G06F3/06
Filed: 1965-04-21
Abstract: 1,083,171. Control of input/output equipment. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 21, 1965 [April 27, 1964], No. 16743/65. Heading G4A. In data processing apparatus, any one of a plurality of input/output (I/O) units can be connected to any one of a plurality of I/O control units through control and data lines by electronic and relay switches respectively when said switches, which are respective to the pair of units, are actuated by the I/O control unit. Selection in this way of one I/O unit by an I/O control unit prevents subsequent selection of the same I/O unit by another I/O control unit until it is free. In the particular embodiment, a computer sends a 9-bit byte (includes parity bit) to one of four " tape control " units to cause it to select one of 16 magnetic tape I/O units. Four of the bits of the byte identify the tape I/O unit, one of these bits (" high order " bit) choosing one set of 8 tape units and the other 3 bits being decoded into a 1-out-of-8 energization to choose one tape unit within that set. By means of switches, the two subsets of 4 tape units within each set may be effectively interchanged (" swapped "). Two further switches enable the two sets of 8 to be effectively interchanged. Further switches enable selection of any particular tape I/O unit(s) by any particular tape control unit(s) to be prevented. When a " tape control " unit has selected a tape I/O unit, command, " sense " (see below) and data bytes (the latter including a parity bit) may be passed between them. After passage of one such byte, the I/O unit is normally free to be selected by another " tape control " unit but the computer may prevent this with a "chain" " signal. The " sense " information, provided by the tape I/O unit, includes model number (indicating data rate effectively), byte size, status, whether tape file is protected &c. Effective interchange of tape units (see above) requires interchange of status lines and this is done by changing the position of a printed circuit card. Longitudinal parity check bytes may be recorded on the tape. Error correction may be done in the " tape control " units after reading from the tape.
