Patent GB-1211493-A (GB)
Title: Improvements in or relating to signal-processing systems
IPC: H04Q3/54
Filed: 1969-02-04
Abstract: 1,211,493. Automatic exchange systems. SIEMENS A.G. 4 Feb., 1969 [6 Feb., 1968], No. 5921/69. Heading H4K. A processor conditions peripheral units to exhibit priority in making demands on processor time when the function of the units requires quick response. The various circumstances in which a processor attributes priorities are described in the context of the exchange network illustrated in Fig. 1. A main exchange network KF serves subscribers Tnsi having impulse transmitting dials and subscribers Ttast having key sending sets. Digits are received by an allocated one of circuits W11 to W1n, and if such a circuit is connected to a key sending-set subscriber the processor ZE over its distributer/ connector Id conditions the circuit to call on the services of the processor as a matter of priority as key-sent digits are received quicker than normal processing would collect. The main exchange also serves a satellite switching centre kf over lines t11 to t1e, ringing current to a satellite station being disconnected at the main exchange in response to reply at the satellite. Since the reply signal is delayed somewhat by transmission from the remote satellite the relay sets R11 to R1l serving the satellite exchange lines are set up to exhibit priority at the ringing stage to obtain rapid processing of the reply signal so as to disconnect ringing before it becomes coupled to the receiver of the called satellite subscriber. The exchange also serves private branch exchanges N1 and N2 which provide for automatic dialling through to extensions over exchange lines such as D1, D2. Circuits such as W21 to W2o are employed for repeating dialled digits to other exchanges, including a PBX, and when such a circuit is employed with repeating PBX extension digits the processor sets the circuit up to exhibit priority for the handling of an "end-of-dialling" signal from the PBX. A fast response is necessary in this context because a PBX will subsequently revert acknowledgment and clearing signals that would be simulated by the dialling signals were the pertinent receiver in the impulse repeating circuit not blocked. When an "endof-dialling" signal is received at the repeating circuit it calls in the processor to unblock the receiver as a matter of priority. The priority indication for a peripheral unit, such as the exchange circuits indicated above, may be established in some circumstances by the unit itself. The processor ZE may serve a number of groups of peripheral units, such as those based on the main exchange KF, each group having its own distributer/connector Id and a buffer store as an interface to the processor. The system may employ three levels of priority.

Title: Process for roasting sulphide ores
IPC: C22B1/10
Filed: 1957-02-21
Abstract: In the fluidised roasting of finely divided sulphide ores, cooled product gas from the roasting operation is blown substantially vertically downwards in a sharply limited and undiffused stream or streams on to the surface of the fluidised bed, in order to promote the settling of small particles suspended in the main upward gas stream.  Such cooled product gas is preferably at 300-400 DEG C., and corresponds to 1/5 -\ba1/6 of the total quantity of air blown through the grate of the furnace.  The downwardly moving gas stream also serves to prevent overheating in the bed and thus prevents slag formation.  The cooled gas may be introduced by a plurality of nozzles, arranged in the top or inside the periphery of the furnace, and directed downwards towards the middle of the bed.  Preferably the cooled gas is blown vertically downwards upon the middle of the bed.

Abstract: 940,150. Prepayment gas meters. UNITED GAS INDUSTRIES Ltd. Feb. 16, 1962 [Feb. 18, 1961], No. 6075/61. Addition to 939, 662. Heading G4V. [Also in Division F2] A shutoff or inlet valve assembly for prepayment gas meters comprises a resilient valve pad 5 coacting with a seat 7 and secured between a disc 1 and washer 6 by a cylindrical body 2 which is formed with a conical or spherical seating 10 for the spherical head 13 of a spindle 11 by which the disc is universally mounted on an operating arm 12. The disc 1 carries a resilient annulus 20 through which, after the valve pad 5 has seated, a restricted flow is permitted, passing by way of a channel &c. in the surface of the head 13 and/or the surface 10 and an orifice 17, until a disc 19 on the arm 12 is brought into engagement with the annulus 20. The secondary valve, instead of being constituted by the parts 19, 20 may consist of a resilient washer carried by an extension of the spindle 11 and coacting with the orifice 17, or an extension of the spindle 11 may be shaped to coact with a resilient annulus concentric with the orifice 17.

Patent GB-434418-A (GB)
Title: Device for eliminating errors in indicating or printing the weights in scales
IPC: G01G23/18
Filed: 1934-02-24
Abstract: 434,418. Weighing-apparatus. SCHENCK EISENGIESSEREI UND MASCHINENFABRIK DARMSTADT GES., C., Darmstadt, Germany. Feb. 24, 1934, No. 6093. Convention date, Feb. 25, 1933. [Class 143] Indicating-mechanism; printed records, apparatus for giving.-Relates to a weighing-scale of the type wherein the results of the weighings are set up on a number of printing or indicating wheels by independent actuating members corresponding to different denominations, and consists in eliminating setting errors at the transition places of the wheels by the provision of stops or locking devices which ensure that the wheels are permitted to register only between their zero and maximum positions. The load on the scale deflects a pendulum lever 3 carrying a ratchet 7, according to the load, and an arm 9 on the pendulum structure sets the hundreds printing wheel 13 by means of a lever 10 and rack 12. The combined tens and units wheel 31 is set by imparting a backward movement to the pendulum until the next tooth on the ratchet 7 engages a stop 14 and arrests the movement. This backward movement is imparted by a falling weight 20 which slides a spring clip 16 in a curved path, the clip being clamped to the ratchet 7 by known means at the appropriate time. The weight at the same time rotates a shaft 30 to which are secured the tens wheel 31 and a ratchet wheel 29 with a cut-away portion 29<3>. A similar ratchet wheel 28 is mounted loosely on the shaft and is connected to the wheel 29 by a pin and slot 34, 35. When the stop 14 arrests the backward movement of the pendulum the impact against the stop causes the stop to liberate a latch 27 extending across both ratchet wheels. The latch then falls into engagement with the ratchet wheels and stops the shaft 30 with the tens wheel correctly set. The presence of the cut away portion 29<3> ensures that the printing wheel shall not be arrested before the zero position is reached. The lost-motion slot 35 allows the relative movement between the ratchet wheels to close the gap in the teeth. A stop 33 which may be resilient in one direction prevents the printing wheel 31 from rotating beyond its highest reading and thereby indicating in error a zero. In a modification, the ratchet wheels 28, 29 are rigid with one another and only one of them is provided with a cut-away portion. The latch 27 engages one ratchet wheel only at a time, and in operation the ratchet wheels are slid by a cam surface along their shaft to bring the appropriate ratchet wheel under the latch. Specification 418,696 is referred to.

Title: Process for isolation of cholesterol from wool wax alcohols
IPC: C07J75/00
Filed: 1948-02-27
Abstract: Chloesterol is obtained from the non-saponifiable component of wool grease by first separating the iso-cholesterol by known means and thereafter purifying the cholesterol from wax-like impurities by selective crystallization of the cholesterol from a simple fatty acid, such as acetic acid, at a temperature of 20 to 25 DEG  C. or by dissolution of the impurity in the same medium at a temperature of 30 DEG  to 35 DEG  C. to separate the cholesterol from the said impurities.  It may be convenient to separate part of the wax residue first by crystallization, e.g. from acetone.  The isocholesterol component, e.g. lanosterol and agnosterol, may be removed by crystallization from methanol.  Detailed examples are given.
Patent GB-985253-A (GB)
Title: Production of refractory metals
Inventor: HEWIN IAN DAVID
IPC: C22C27/02
Filed: 1963-02-15
Abstract: A refractory metal (i.e. Ti, Zr, Hf, V, Mo, W, Re, and especially Ta or Nb, or alloys of these metals with one another) is produced by reacting the oxide thereof with a reactive metal (Al, Ca, Ce, Mg, B, or Si) to form an impure alloy of the refractory metal containing a small amount of the reactive metal and subsequently electron beam melting the alloy under high vacuum to reduce the content of reactive metal and other volatile impurities.  The oxide starting materials may be relatively pure oxides or oxide mixtures, or ore concentrates containing a large percentage of oxide.  The reaction causes a slag to form so a protective atmosphere of argon is unnecessary but may be used. The reactants are preferably mixed in powder form and the reaction may be initiated by passing a current through a wire of the reactive metal embedded in the mixture or by an oxyacetylene flame.

Filed: 1951-03-15
Abstract: 705,177. Linear-dimension gauges ; ganging surface roughness. SHEFFIELD CORPORATION. March 15, 1951 [March 16, 1950], No 6258/51. Class 106 (2) A device for gauging linear dimensions or surface roughness comprises a source 10, Fig. 1, of fluid under pressure connected to a leakage orifice 18 in a gauging head 15, the fluid pressure behind the leakage orifice 18 acting through pipes 19 on one side of a flexible diaphragm 20, Fig. 3, the other side of which is open to atmospheric pressure at 26 but varies by its displacement the rate of flow of air from an air leakage nozzle 27 adjacent to and discharging against this said other side of the diaphragm 20. The resulting pressure changes behind the air leakage nozzle 27 are an amplified measure of the pressure changes behind the leakage orifice 18. These amplified pressure changes may be gauged by suitable means or they may act on pressure controlled electric switches 38, 39, 40 connected to the nozzle 27 by a pipe 28. The pressure behind the leakage orifice 18 may act on more than one diaphragm, each diaphragm controlling an air leakage nozzle and each air leakage nozzle may be connected to its own group of pressure controlled electric switches. With such a plurality of diaphragms, the normal spacing between each nozzle and its adjacent diaphragm differs from that of the others. In Fig. 1, the source 10 of fluid pressure to the pipes 19 and 28 is made through pressure regulators 11, 12, 32 and adjustable air restricting valves 13 and 34. As shown the pressure changes behind the orifice 18 also act on two flexible diaphragms in a casing 48, each diaphragm having an associated nozzle, one nozzle actuating the pressure controlled electric switches 63, 64, 65 and the other the switches 66, 67 and 68. The switches may control indicating or selecting means.
