Title: Stable injectable protamine-active compositions
IPC: A61K47/20
Filed: 1962-05-22
Abstract: Injectable compositions, for use in the combating of malignant tumours, comprise in dosage unit form in admixture with a parenterally acceptable pharmaceutical liquid carrier from 250 to 6000 mg. of protamine which may be in the form of the free base, a physiologically acceptable acid addition salt thereof or a protamine-active compound.  The compositions can be stabilized by the inclusion of a formaldehyde-bisulphite or formaldehyde-sulphoxylate complex.  Where such a complex is heated with protamine in aqueous alkaline solution, a protamine-active compound is formed.  The bisulphite or sulphoxylate moiety of the formaldehyde complex is preferably in the form of an alkali metal salt, e.g. potassium or sodium salt. Suitable salts of protamine include the hydrochloride, hydrobromide, phosphate, nitrate, citrate, tartrate and sulphate. In examples, the protamine used is salmine (from salmon) and clupeine (from herring).  The carrier is preferably sterile pyrogen-free water, optionally containing salts such as sodium chloride.

Title: Thermionic valve delay circuits
IPC: H03K5/13
Filed: 1944-10-18
Abstract: 590,484. Pulse delaying circuits. STANDARD TELEPHONES & CABLES, Ltd. Oct. 18, 1944, No. 20198. Convention. date, March 20, 1942. [Class 40 (v)] Each pulse of a train is applied to a saw tooth generator, the resulting saw-tooth wave being limited at a specified value by an amplitude limiter, a corresponding rectangular waveform being derived from the output which. after differentiation, provides pulses corresponding to the initiation of the saw-tooth and the moment at which the saw-tooth reaches the specified value. Input pulses, fed to valve T1, are applied as positive pulses to the grid of valve T2 to discharge condensers 18, 19 which subsequently charge over resistance 17 to generate a saw-tooth when the pulse terminates. The switch 16 is placed in the lower or upper position according to whether the input pulses are of positive or negative polarity. The saw-tooth wave is fed to an over-biassed valve T3 to develop a positive-going rectangular wave on the cathode which is differentiated over condenser-resistance combination 22, 23 producing a delayed positive pulse and a negative pulse coincident with the input pulse. These pulses are fed to over-biassed valve T4 to suppress the negative pulse, the delayed positive pulse being amplified and appearing at the cathode or anode load with the desired polarity. In a modification, Fig. 3 (not shown), the saw-tooth wave is fed to a biassed diode which truncates the wave, the output wave being differentiated to produce a sharp negative pulse followed by a positive-going longer portion. After amplification in an over-biassed valve, the resulting negative-going rectangular wave is differentiated to feed the output valve.

Title: Improvements in and relating to the manipulation of strands or yarns
IPC: B65H69/04
Filed: 1921-08-02
Abstract: 167,753. Taft, E. A., (Assignee of Barker, R. W.). Aug. 13, 1920, [Convention date]. Knot - tying devices.-One strand is held stationarv and a knot is tied by passing the end of the other strand about the stationary strand, the kind of knot determining the path of the stran'd end. In knot-tying mechanism, the strand end is carried by a hookmember moving in a raceway of special shape and propelled by means of an endless chain of bearing balls. A knot, so tied, is not entangled with the tying instrument but its convolutions pass easily between the balls of the driving chain. In a knotter for tying weavers' knots, a threadend carrier 60, Fig. 12, is mounted in a continuous race 16 of the special form shown in Fig. 11, and is driven to and fro by means of a series of balls filling the race from end to end of a driver 17. The threads are place'd as shown, the thread A lying in slots 56 cut right through the raceway. When the driver is moved upwards, the balls carry the carrier 60 around the race parts 42 and 43 and into the part 46, thereby producing the convolutions shown in Fig. 15. By pulling upon the right-hand end of the thread A, that thread is brought freely between the balls in the raceway and out of the slots 56 and the threads are tightened upon one another in the form of the required knot. The same raceway can be used to form a spooler's knot if one of the cross-slots 56 is masked by a plate 205, Fig. 25. 'The two threads are laid side by side in the remaining slots and when the carrier is actuated to carry the free ends of the two threads along the raceway, a knot is formed as shown in Fig. 25. Other knots can be formed by providing suitably shaped raceways. A hand-carried knotter for tying weavers' knots is described in full and includes means for guiding the two threads to their initial positions, and for cutting the thread A first and the thread B at a later point in the cycle, and a device which holds the uncut part of the thread, and at the completion of the concatenation pulls the threads clear of the ball race and tightens them into a knot.

Filed: 1927-08-05
Abstract: 276,649. British Thomson-Houston Co., Ltd., (Assignees of Rankin, W. K.). Aug. 30, 1926, [Convention date]. Oil switches for high voltages and heavy currents comprise an oil tank 1 from the bottom of which the explosion chamber 10 is supported carrying segmental socket contacts 15 and upper segmental contacts outside, the explosion chamber, and a bridging contact-rod 16 which is raised rapidly to the off position by oil pressure transmitted through the passage 9. The oil pressure is produced by a piston 38 which is first raised against the action of a powerful spring 45 and locked in the raised position by levers 48. 49 geared together and having roller ends engaging a cam surface on an extension 41 of the piston rod. The links are maintained in the set position by an overset toggle 52 which can be tripped by the electromagnet 53 or by hand. When tripped the spring depresses the piston and forces the contact-rod 16 upwards out of the contact 15, the rod being followed by a stream of cold oil which extinguishes the arc. The contact-rod is raised against the action of a spring 28 and in the upper position is engaged and retained by a spring-latch 33. In this position. the piston 38 can be again raised and held in the upper position and then the latch 33 withdrawn to permit the spring 28 to press the rod into the contactmaking position again.
