Title: Twisted thread assemblies
IPC: D02G1/08
Filed: 1967-08-01
Abstract: 1,144,614. Twisting. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. 1 Aug., 1967 [9 Aug., 1966], No. 35354/67. Headings D1F and D1W. A process for forming a stable twisted thread assembly, comprises individually twisting at least one strand of a group of strands so that each twisted strand has repeated along its length successive zones of opposite twist separated by strand twist changeover regions at which there is no twist, converging the strands of the group so that they twist around one another such as to form a stable first thread having successive zones of opposite plying twist separated by plying twist change-over regions at which there is no plying twist, twisting said first thread to superimpose alternately opposite twist in successive zones along its length which latter zones are separated by superimposed twist change-over regions! of no superimposed twist, and converging the twisted first thread with a second thread so that the two threads twist around one another to form a stable twisted assembly. The second thread, before it is converged with the first thread, may be twisted such as to impart alternately opposite twists to successive zones along its length which latter zones are separated by change-over regions of no imparted twist, and in addition may comprise strands twisted similarly to the strands of the first thread. The strands and threads may be twisted by two pair of rollers axially reciprocated as in Specification No. 1,121,942 with the rollers of the second pair (which twist the threads) reciprocating at the same stroke as or at smaller stroke than the rollers of the first pair (which twist the strands). The length of the thread path from the point of convergence of the strands at the first pair of the rollers to the second pair of rollers may differ for the two threads, while the strand (or thread) path between the rollers and the points of convergence of the strands (or threads) may differ for the strands (or threads) so that the zones of twist in the strands (or threads) are out of phase. In examples there are two wool strands in each of two threads, or the second thread comprises a synthetic yarn and the first thread two wool strands or one wool strand and one synthetic yarn. The synthetic yarns may be mono- or multi-filament yarns of nylon, polypropylene, alginate, rayon, a polyester or an acrylic. Wool strands may have been treated with colloidal silica to increase the inter-fibre friction.

Abstract: 1 : 1-Difluoro-2 : 2-dimethylethylene, (see Group IV (b)), is polymerized at about 80 DEG  C. with benzoyl peroxide to give a product useful as a high frequency and high temperature dielectric.ALSO:The invention comprises 1 : 1-difluoro-2 : 2-dimethylethylene, CF2 = C(CH3)2 and methods of preparing it by hydrogenating 1 : 1-difluoro-1 - chloro - 2 - methylpropene - 2, with rearrangement, by usual methods, and by the method below. The fluorochloropropene may be prepared by the action of PCl5 on difluorchloromethyl dimethyl carbinol, and the carbinol by the action of methyl magnesium halide on difluorochloroacetyl chloride.  In examples, difluoromethyl dimethyl carbinol prepared as described above gives 1 : 1-difluoro-1-chloro-2-methylpropene-2 with PCl5, which on reduction with hydrogen and Raney nickel, or Li AlH4 in tetrahydrofuran, gives the 1 : 1-difluoro-2 : 2-dimethyl ethylene; or the carbinol is converted to the trialkyl phosphite: (CF2ClC(CH3)2)PO3, which is reduced with activated zinc dust to give the 1 : 1-difluoro-2 : 2-dimethylethylene.

Title: A method of reducing the albuminoid concentration and lowering the viscosity of ovalbumin
IPC: A23L15/00
Filed: 1960-10-15
Abstract: The albuminoid concentration and viscosity of ovalbumin is reduced, while at the same time retaining its working properties, by forming a homogeneous mixture thereof with acid whey or rennet or a mixture thereof.  The concentration and viscosity may be so reduced that the resulting mixed proteinate can pass through anion or cation exchangers, and furthermore can subsequently be sterilized e.g. by passage through a sterilizing filter or by heating to 100 DEG C.  The pH of the resulting mixed proteinate can be reduced to a value of about 2.0 by the addition of suitable acid, or the proteinate can be neutralized or alkalized by the addition of suitable alkali; the proteinate can be subsequently be sterilized.

In a combined disc and shoe-drum brake of the kind in which " flat shoes " 12, 14 are spread apart into engagement with the inner radial sides of a rotatable drum and the circumferential movement imparted thereto transmitted to produce radial applying movement of a shoe 16, the transmission means comprises a lever 50 pivoted at 52 so that for the normal anti-clockwise direction of drum rotation, for which the shoe 16 acts as a trailing shoe, the force transmitted from the pads 12, 14 is increased in the ratio A/B, Fig. 11. Thus, by this arrangement, the brake torque produced by shoe 16 acting as a trailing shoe will be substantially the same as that when the drum rotation is reversed and it acts as a leading shoe with applying force transmitted through strut 54 at a leverage ratio of A/C, Fig. 11. As shown in Fig. 4, the friction members 12, 14 are spread apart by a single piston and cylinder unit acting through articulated levers 18. The strut 56 incorporates automatic adjustment mechanism for the shoe movement. Specification 758,882 is referred to.

The compounds are made by reacting acrylonitrile with HCl in equimolar proportions to produce 3-chloropropionitrile which is subsequently reacted with an a -olefine RCH = CH2 in the presence of concentrated H2SO4 to give N-(2-alkyl)-3-chloropropionamide which is sulphonated by heating with an alkaline sulphite. In an alternative method the olefine is reacted with acrylamide to give the N-(2-alkyl) acrylamide which is then sulphenated in the presence of a bisulphite.  The compounds are used in detergent compositions (see Division C5). Examples relate to compounds in which R is (1) -C12H25, (2) derived from a mixture of C10- 14 alkyl groups and (3) derived from a mixture of C11- 13 alkyl groups.

Filed: 1976-09-02
Abstract: 1527160 Multiplexing INTERNATIONAL STANDARD ELECTRIC CORP 2 Sept 1976 [10 Sept 1975] 36430/76 Heading H4M In a system such as a computer or a telephone exchange in which clocking signals from a transmitter are sent to different receivers, auxiliary signals for use by the receivers, e.g. for the energization of frequency dividers in the receivers, are transmitted by modifying the clocking signals so that a separate channel for the auxiliary signals is not required. As shown, periodic two-level clocking signals H having transitions in a first direction and in a second direction are produced by the transmitter. An auxiliary signal A to be transmitted together with the clock signals produces a pulse F which is added to the signal H so that a rising edge of the latter is shifted in time, as shown by a double line in waveform T of the figure. The amount of time shift is a function of the auxiliary signal A, and the receiver is adapted to reconstitute the clock signal H and the auxiliary signals A from the received waveform T, suitable circuit arrangements using a retriggerable monostable to detect the time shift being described with reference to Figs. 1, 4 and 7 (not shown).
