Title: Improvements in or relating to Telecommunications Exchange Systems Switching Networks
IPC: H04Q3/00
Filed: 1968-04-24
Abstract: 1,172,329. Automatic exchange systems. SIEMENS A.G. 24 April, 1968 [25 April, 1967], No. 19311/68. Heading H4K. In a multistage switching network comprising matrices of remanent relays, in each matrix each row of cross-point relays has associated therewith a two-winding non-remanent release relay. In order to release a connection the latter relay is operated over its operate winding, e.g HB11 I (the relay associated with the first row of the first matrix in stage B) by the extension of earth from a preceding stage through the closed cross-point, e.g. b111 in its row. Thereupon a circuit is completed, at hb11, for the release winding of the remanent cross-point relay B111 II and for the extension of earth to the next stage. A similar process is repeated at each stage, the row release relays being held over their second windings in each case. In the final stage the release of the cross-point relay, e.g. A111, drops the associated row relay HA11 and also causes the row relay in the just-released preceding stage to fall back. It may be noted that the subscriber's remanent cut-off relay T11 is released when the relevant row relay HA1 operates.

Filed: 1920-07-07
Abstract: 169,318. Southern, M. E. July 7, 1920. Tufted fabrics.-Fleece wool articles are made by forming loose fleece wool, or goats' hair, into tufts a, knotting the tufts at their shorn ends b, and threading them into a backing c, to which they are secured by stitches &c. The knotted ends of the tufts may be crocheted into a piece of crochet-work, which forms an integral backing for the tufts. The tufts may be dyed and combed after attachment to the foundation to give the appearance of unshorn wool on its natural skin. According to the Provisional Specification, the tufts may be formed into half-loops and stitched centrally to the backing.

Title: Improvements in therapeutic product and process of obtaining the same
IPC: A61K39/04
Filed: 1935-07-08
Abstract: Sterile dry therapeutic and like preparations containing a very small proportion of a highly active substance are prepared by mixing in one or more steps a solution of the active substance with a solution of a diluent, concentrating the mixed solution to dryness and then admixing with the dry product more of the diluent, also in dry form, the operations being conducted under aseptic conditions.  The preparations may be formed into tablets using a vehicle such as 90 per cent alcohol and a little preservative such as tricresol. According to an example a highly purified tuberculin protein dissolved in very dilute aqueous caustic soda is mixed with an aqueous solution of milk sugar, and the combined solution filtered, tested for sterility, and evaporated to dryness at low temperature under vacuum.  The residue is ground in a ball mill and then further ground after addition of dry milk sugar.  The tuberculin protein employed is obtained from the filtrate of a culture of bacterium tuberculosis (human type) on a synthetic medium, by ultradialysis followed by precipitation of the protein by trichloracetic acid. Other active materials referred to are protein extracts, pollen extracts, bacterial proteins, alkaloids, gland extracts, and hormones such as the anterior pituitary hormone; other diluents specified are boric acid and cane sugar.

Title: Improvements in arrangements for generating synchronous pulses and scanning voltages
IPC: H03K4/16
Filed: 1943-11-24
Abstract: 584,606. Saw - tooth generators. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Nov. 24,1943, No. 19611. [Class 40 (v)] A scanning wave and marking pulse, derived from a relaxation oscillator, are applied to an oscillograph, the shape of the scanning wave being variable without affecting the repetition frequency of the oscillator. The marking pulse is used as a reference point on the cathode-ray screen trace and may be employed to synchronize the transmitter in a radiolocation system. The blocking oscillator valve V1, Fig. 3, back coupled over transformer T1, generates a marking pulse across resistance 5 when the valve conducts. The flow of anode current charges condenser 10 which discharges slowly over resistance 11 to form the scanning wave until the valve VI conducts again. The frequency of oscillation, determined by the time constant of condenser 1 and resistance 2, is substantially unaffected by changes in condenser 10 and resistance 11. In a modification, Fig. 7 (not shown), the resistance 11 and condenser 10 are fed over a resistance from the output voltage developed across resistance 5, the remote end of the condenser 10 being connected to the anode of a diode, the cathode of which is earthed. For producing a scanning voltage shorter than the period of the blocking oscillator valve V1, Fig. 8, the voltage across condenser 1 is fed through an amplifier V3 to a valve V4 normally biassed beyond cut-off by a voltage supplied to potentiometer 29. Only the positive peaks are amplified in valve V4, the resulting negative-going wave being amplified by valve V5 to produce the positive-going scanning wave-form across the anode load. The grid resistance of valve V1 consists of a pentode V2. synchronizing pulses being applied to the grid,

In an hydraulic brake system of a vehicle, such as a fork-lift truck, which when loaded has the greater proportion of the total weight supported by its front wheels and when unloaded has the greater proportion of its weight supported by its rear wheels, owing e.g. to the provision of a counterweight at the rear, either a tandem master cylinder 32, as shown, having high and low pressure outlets 33, 34, or an equivalent arrangement (Fig. 3, not shown) comprising an ordinary master cylinder with which is associated a pressure intensifier (71), is used to supply high and low pressures to rear and front wheel braking circuits 35<1>, 451 via a reversing valve 51 controlled by a solenoid or other transducer 53 which is operated in accordance with the load being carried so as to cause the higher pressure to be fed to the rear wheel brake cylinders 37 when the vehicle is unloaded and to the front wheel brake cylinders 41 when the vehicle is loaded, the lower pressure being fed to the front and rear wheel brake cylinders respectively. Operation of the solenoid 53 is under control of a switch 56 which is operated by the pressure in the hydraulic ram 15 which operates the fork-lift carriage, such pressure acting by way of a conduit 59 on switch plunger 62 so as to open the switch when the vehicle is loaded, the switch being closed by a spring in the unloaded condition shown. Should a failure occur in the electrical circuit the valve 51 therefore changes over to the loaded condition whether the vehicle is loaded or not.

Title: Phthalocyanine sulfonhydrazides
Filed: 1946-07-02
Abstract: A phthalocyanine sulphonhydrazide is prepared by condensing a phthalocyanine sulphonyl chloride with a hydrazine.  The hydrazine may be hydrazine itself or a primary or secondary alkyl, substituted alkyl, alicyclic, aryl, or heterocyclic hydrazine, numerous examples of which hydrazines are given.  The phthalocyanine may be a metal derivative such as a copper, cobalt, nickel, iron, or aluminium derivative, and the aromatic nuclei thereof may be phenyl, diphenyl, naphthyl, or anthranyl nuclei. These nuclei may contain substituents such as halogen atoms (e.g. chlorine) or amino or carboxy groups, or sulphonic acid groups which may be free or converted to hydrazine salts.  The reaction may be effected at room or elevated temperatures in presence of a diluent such as water, alcohol, acetone, nitrobenzene, or excess hydrazine.  Dyes having a plurality of sulphonhydrazide groups with a free hydrogen atom on the nitrogen atom of the sulphamyl portion are soluble in dilute aqueous caustic alkali.  In examples, copper phthalocyanine tetrasulphonyl chloride is reacted: (1) with hydrazine hydrate at room temperature, and the dye precipitated by stirring into aqueous HC1; (2) with phenyl hydrazine and the dye similarly precipitated; and (3) with 4-sulphophenylhydrazine in nitrobenzene with heating.  Phthalocyanine sulphonyl chlorides are prepared either by reacting phthalocyanines with chlorosulphonic acid at an elevated temperature as described in Specification 515,637, or by treating the corresponding phthalocyanine sulphonic acids or salts thereof with phosphorus pentachloride.  Specification 520,199 also is referred to.
