Abstract: 1,131,268. Crimping yarns. JOSEPH BANCROFT & SONS Co. 28 Sept., 1966 [18 Oct., 1965], No. 43437/66. Heading D1F. In a stuffer-box crimper, the height of a core of crimped yarn in the upper, discharge end of the tubular compression chamber is sensed by an upper feeler arm projecting through a vertical slot in one wall of the chamber and resting on the core. The arm is adjustably weighted so as to maintain a selected back-pressure on the core and its movements are communicated to a control pulley, on an adjustably weighted, lower arm of the feeler, the position of which is thereby adjusted so as to tighten or loosen a belt drive to feed (or withdrawal) rollers to adjust correctively the ratio of the yarn feed with respect to yarn withdrawal so as to maintain the end of the core at a constant level.

Title: Anti-protein to human chorionic gonadotrophin
IPC: C07K16/26
Filed: 1965-10-20
Abstract: A diagnostic reagent for pregnancy determination similar to that of Specification 1,078,939 contains an anti protein for human chorionic gonadotrophin, (HCG), derived from the blood serum of animals rendered immune to HCG by repeated injections thereof, and extracted by adsorbing the anti-protein on water swollen particles of cross-linked dextran containing random ether linkages, such as Sephadex G; (Registered Trade Mark), and then eluting the anti protein.  (see Div. A5-A6).  For use the anti-protein is adsorbed on polystyrene latex particles which preferably have an average diameter of from 0.5 to 1.3 microns.  The reagent consists of the anti-protein coated polystyrene particles in suspension in an aqueous solution containing 0.45% to 1.5% glycine, 0.2% to 0.45% of the sodium salt of EDTA, 4% to 6% albumin, 0.05% to 0.1% sodium azide, and triethanolamine to adjust the pH to from 8.2 to 8.6.ALSO:A specific anti-protein to human chorionic gonadotrophin (HCG) is isolated from the blood serum of a lower animal containing the anti-protein by adsorbing the serum on water-swollen particles of cross-linked dextran containing random ether linkages to glucose residues in the polysaccharide chains (e.g. Sephadex G; Registered Trade Mark), eluting the anti-protein, and recovering it from the eluate.  Elution is suitably effected with an aqueous solution of sodium chloride and tris (hydroxymethyl)-aminomethane of pH 8.0, the same reagent being used to swell the dextran gel. As a serum source, animals such as rabbits may be immunised with a number of injections of a commercial human HCG preparation, the animals being bled when a suitable anti-serum titre has been reached.  Recovery of the anti-protein from the eluate is by lyophilisation, re-solution and dialysis.  The HCG anti-protein is of use in preparing a pregnancy diagnostic reagent, by adsorption on to polystyrene latex particles (see Div. B1-B2)

Heading H3P. A sweep voltage generator particularly for a cathode-ray tube comprises a series resonant circuit 35, 36 shunted by a switching device such as vacuum tube 39 and a further capacitance 50, of lower value than 36, the circuit being chargeable from a power source via a resistive path 38 having a greater resistance than device 39. When a positive pulse is fed to the grid of tube 39, capacitance 50 of the deflection plates 41 of the cathode-ray tube 42 discharges resonantly at a frequency determined by the constants of components 35, 36. At the end of the pulse, tube 39 becomes non- conductive so that the circuit re-charges resonantly at a frequency determined primarily by 50, 35 giving a substantially linear portion of a sinusoidal wave which is fed to deflection plates 41. The sweep amplitude may be adjusted by changing the duration of pulse 44 or by adjustment of the resonant frequency or supply voltage. Expressions are given for the effect of damping.

Patent GB-452517-A (GB)
Abstract: 452,517. Momentary-contact switches. BENSON, J., 11, Museum Street, Warrington. March 1, 1935, No. 6454. [Class 38 (v)] A momentary-contact switch has a sliding circuit closing member which is moved to its operative position in which it bridges a gap in the circuit by the switch operator, this member carrying with it a momentary contact switch member which is released automatically to close the circuit when the sliding member arrives at the position in which it bridges the gap. As shown, when an operating bar 18 is drawn downwardly it carries with it a member 7 carrying a contact 8 and also by means of a projecting pin 10 engaging a recess in a spring-controlled hooked catch 11 a member 9 carrying sliding contacts 19 is also moved downwardly. At the lower limit of the travel of these members the member 8 bridges fixed contacts on a base 30 and the tail 11 of the catch engages a fixed stop 13. The member 9 is thereby released and drawn upwardly with a rapid action by the spring 15. During this movement the plungers 19 wipe over a live contact 28 so that a circuit is momentarily completed through the contacts bridged by member 8, contact 28 bridging members 19 and the opposite slide contact 22. The lower edge of the contact 28 is tapered so that by lateral adjustment of this contact the period of contact may be varied. The operating rod 18 on release is returned by a separate spring, the latch 11 being automatically re-engaged at the end of the return movement in readiness for a further operation.
