Title: Improvements in or relating to furnace linings
IPC: F27D1/00
Filed: 1934-06-22
Abstract: A furnace lining which is subject to attack by slag is made wholly or in part of refractory material having a porosity of at least 35 per cent.  The requisite porosity may be obtained by incorporating with the material combustible or volatile substances, or by choosing a suitable grain size, e.g. ,4-,5 mm. and using a relatively small quantity, say 10 per cent of binder.  The lining material may be burnt in situ as a plastic mass or pre-formed shapes, or pre-burnt bricks may be used.  The refractory material may be silica, magnesite, alumina, chromite or chamotte, and provided that the material is sufficiently strong, it may have a porosity up to 80 per cent.  Reference has been directed by the Comptroller to Specification 21781/96, [Class 22].

Patent GB-655035-A (GB)
Title: Improvements in the manufacture of moulded bodies from metal powder or powder of metal carbides
IPC: C22C1/05
Filed: 1947-07-15
Abstract: Metal or metal carbide powder is moulded in moulds made of steatite or of graphite compressed and moulded at a pressure of the order of 4000 kg./cm2.  The moulding of the metal or carbide powder is effected at a low pressure of the order of 50-100 kg./cm2 in steel moulds, due to the low friction between the metal or carbide powder and the graphite or steatite mould.  The mould may be surrounded by a tight fitting metal sleeve exerting a spring pressure on the mould and consisting preferably of two halves clamped together by screws. The compressed powder may be removed from the mould for sintering or preliminarily sintered in the mould and finally sintered outside the mould.  Compression of the metal or carbide powder is facilitated by the use of a wetting agent, e.g. alcohol.

Title: Process for treating ores
IPC: B03C7/00
Filed: 1956-06-18
Abstract: 812,178. Treating ores. DIAMOND, G. S. June 18, 1956, No. 18808/56. Class 82(1) A method of treating an ore containing crystals of a mineral capable of picking up a surface electrostatic charge and crystals of a mineral more inert to such charges, comprises the steps of determining the average crystal size by a petrographic study and fracturing the crystals to produce fragments of the first-named mineral smaller in size than its natural crystals and therefore having clean exposed crystalline surfaces; without chemical pretreatment subjecting all fragments of the ore to conditions which generate electrostatic charge on the fragments of the first named mineral, and separating those with the greater charge from the rest by passage through an electrostatic field; and either before or after said passage subjecting the fragments to a magnetic field to remove magnetically affected wastes. Fig. 1 shows the six main steps as applied to fleldspar ores, steps 5 and 6 being interchangeable. Electrostatic charges are induced by heating and agitation immediately before the particles enter the electrostatic separating field. Where mica is present, this is preferably screened off (step 3) and itself subjected to a magnetic field.

Patent GB-766871-A (GB)
Title: Improvements in and relating to code impulse generators for use in electric signalling systems
IPC: B61L7/08
Filed: 1952-07-29
Abstract: 766,871. Railway track signalling circuits. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., AUSTIN, T. D., and RIDDLE, H. J. N. July 29, 1953 [July 29, 1952], No. 19150/52. Class 105. [Also in Group XXXVIII] A code impulse generator for generating different impulse codes, for example, for application to a coded track circuit of a railway signalling system, comprises a plurality of slowrelease relays arranged to form a timing circuit the cycles of operation of which are counted and recorded on a group of relays of which different combinations determine the impulse codes and are applied to control the times and durations of operation of a further relay which applies the impulse codes to the transmitting medium. In a modification of the invention different combinations of the timing circuit relays determine the impulse codes and control the times and durations of operation of respective executing relays which apply their respective codes to the transmitting medium. As shown, three slowrelease relays AT, BT, CT, interconnected so that b.c. CT1 (back contact CT1) energizes and picks up relay AT which at f.c. AT1 (front contact AT1) picks up relay BT and this relay BT at f.c. BT1 picks up relay CT to release at b.c. CT1, relay AT followed in due course by relays BT and CT to start again a new cycle. When b.c. CT1 closes, relay AT picks up and at f.c. AT2 relay IT of the counting group of relays 1T-8T, is picked up over b.c. 8T1-2T1 and held over f.c. 1T2 and its lower winding and b.c. 2T2-8T2. When relay AT drops away, at b.c. AT2, relay 2T picks up over f.c. IT3 and is held over f.c. 2T2 and b.c. 3T2-8T2. At b.c. 2T2 and 2T1 relay IT is released. When relay AT again picks up relay 3T picks up over f.c. AT2 and f.c. 2T3'and so the counting proceeds so that with 8 counting relays four cycles of the timing circuit are recorded. The codes are represented by various combinations of paralleled front contacts of the counting relays as indicated and these front contacts energize the transmitting relay TR which at f.c. TR1 applies electrical impulses to the track circuit. An embodiment of the modification is also described.

Title: Production of phenols from aromatic carboxylic acids
IPC: C07C37/56
Filed: 1958-06-16
Abstract: A process for preparing phenolic compounds comprises bringing a monocarboxylic acid of the benzene series in which the carboxyl group is attached to the ring and where there is at least one unsubstituted position ortho to the carboxyl group on the ring and where any other substituents are substantially inert to the oxidizing action of cupric oxide and are selected from phenyl, alkyl, alkoxy, nitro and halogen, into contact with an oxidizing agent consisting essentially of cupric oxide under atmospheric or superatmospheric pressure at a temperature of at least 200 DEG  C. but below a temperature at which destructive carbonization takes place and in the absence of elemental oxygen, until oxidation and decarboxylation of the acid has occurred, if necessary releasing the pressure and finally recovering the so-produced free phenol from the reaction medium.  An oxidation and decarboxylation reaction is considered to take place so that the product contains the hydroxy group ortho to the original carboxyl group.  A preferred embodiment consists of heating benzoic acid with at least an equivalent amount of cupric oxide at 250-280 DEG  C. and displacing the phenol from the reduced copper body by passing a stream of inert gas, e.g. steam, through it at 275-500 DEG  C.  A further embodiment comprises bringing in sequence a solid mass comprising cupric oxide, preferably in a multiple zone moving bed reactor system, into contact with benzoic acid at 200-400 DEG  C. until substantial reduction of the cupric oxide has occurred, then into contact with an aqueous medium preferably liquid water, to strip phenol from the reduced mass, then into an oxidizing zone to convert the reduced mass to cupric oxide and finally repeating the cycle and recovering the phenol from the aqueous medium.  The phenol may also be recovered from the reduced copper mass by steam stripping.  The cupric oxide oxidant may be promoted with cobaltic oxide if desired. The phenolic products obtained from various acids are specified.

Title: Improvements in or relating to fluid pressure gauges
IPC: G01L7/04
Filed: 1929-06-25
Abstract: 329,209. Griffith, A. A., and Lockspeiser, B. June 25, 1929. Bourdon pressure gauges. - The gauges are constructed by blowing a bulb on the end of a tube of silica or other vitreous material of small thermal expansion, treating the bulb so as to form an annular chamber, interrupting the annulus, and closing the ends at the interruption. A bulb is first blown and then is heated by a blow-pipe at one end of a diameter at right angles to the tube. At the same time air is sucked from within the bulb until the wall has fallen in to a certain extent, when the wall at the other end of the said diameter is similarly treated until the walls fuse at the centre a. A small flame is then applied to pierce the centre. The surface tension of the silica draws it away from the centre and spreads it to form an annular tube of substantially uniform thickness. A lower temperature blowpipe flame is now applied to a point near the stem until the walls touch and separate the two closed ends, these being rounded as in Fig. 5. A pointer or mirror may be attached at the free end x for magnifying its movement. The gauge is adapted for small pressures, resists chemical action, withstands high temperatures and has no hysteresis effect.

Title: System for in-flight control of projectile fuse
IPC: F42C9/00
Filed: 1976-05-13
Abstract: The intended type of firing, that is to say impact, slow or delayed firing previously had to be set before the projectile was launched. The present circuit installed in the projectile makes it possible, in interaction with a suitable transmitter, to set the type of firing, the time of arming of the fuze and the firing delay time during the flight of the projectile. For this purpose, the electronic circuit contains a receiver (56) for a carrier frequency which is modulated with repetitive trains of pulses of different width, and a demodulator (64) which converts the pulses into different binary signals. Furthermore, a shift register (66) is provided in which the sequence of binary signals corresponding to the pulse train is stored. The binary signal sequence forms a code character for one of a number of possible types of firing of a projectile fuze. The circuit contains at least one oscillator (50) with a constant frequency, the pulses of which are counted in a counter (60), starting at the time of arming. When a predetermined number of pulses has been counted in the counter, firing is triggered. To shorten the running time of the fuze, the received pulses can also be counted in the counter in addition to the pulses of the oscillator. <IMAGE>
