Title: Improvements in or relating to explosive mine anchor-line cutters
IPC: B63G7/04
Filed: 1944-12-29
Abstract: 814,378. Shearing. MINE SAFETY APPLIANCES CO. Dec. 29, 1944 [Oct. 2, 1943], No. .26148/44. Class 83 (4). [Also in Group XXI] A cutter for a submarine anchor line comprises a cutter 12 adapted to be driven into a recess 11 for receiving the mine anchor line 21, by an explosive charge 22 fired by firing mechanism operated by the entry of the anchor line into the recess but only when the device is submerged in water. The anchor line 21 is guided into the recess 11 by a gate member 51 adapted to close the entrance to the recess after the anchor line has entered to prevent entry of a second anchor line. The charge 22 is fired by a pin 28 operated by a lever 32 and a piston 37 which is operated hydraulically by a plunger 47 by means of the water trapped in the bore 36 containing the piston 37. If the device is not submerged, no water is contained in this passage and the plunger 47, is operated accidentally, is stopped by a rectangular portion 38 before it strikes the piston 37. The plunger 47 is spring- operated and is normally retained inoperative by a trip pir 46 adapted to be bent by the entry of the mine anchor line into the recess and thus withdrawn from the plunger. The cutter 12 operates against an anvil 16 held by a pin 17 which is sheared when the cutter operates and the head 18 of the pin 17 releases the gate 51 which is moved across the recess by a leafspring 53. The cutter is normally held inoperative by a shear-pin 13. The cutter frame is carried by a stabilizing fin 1 held on the towing cable by hooked ears 3, 4 and bolts 6 and located on the cable by a tapered collar 7. The firing mechanism is contained in a removable breech block 23.

Title: Pressure regulator for flowing media
IPC: G05D16/10
Filed: 1975-06-20
Abstract: 1473049 Fluid-pressure servomotor systems HOERBIGER FLUIDTECHNIK KG 20 June 1975 [21 June 1974] 26392/75 Heading G3P A pressure regulator having inlet and outlet ports 2, 3 and a main valve 5 actuated by servopiston (or diaphragm) 9 is provided with a compensating spring 20 acting between piston 9 and pilot relief valve 15 such that as main valve 5 opens, the opening bias of the spring on valve 15 is reduced so that the control pressure in chamber 10 above piston 9 increases causing the latter to open main valve 5 further to compensate for the increased pressure losses through the regulator resulting from the higher rate of flow. Additional compensation is achieved by a duct 23 which connects a throat 24 adjacent outlet port 3 with a chamber 11 below piston 9 so that the chamber pressure decreases with increasing flow-rate. Compensating spring 20 may have linear or non-linear characteristics. As shown, the control pressure in chamber 10 is supplied from the regulator inlet 2 via passage 13 and restriction 14, but in a modification the pressure is supplied from a separate source. The output pressure of the regulator is pre-set by adjusting hand wheel 18 to vary the closing bias of spring 17 upon pilot valve 15.

Title: Process and apparatus for the continuous production of mouldings from high-silica-content raw materials
IPC: C03B5/18
Filed: 1964-06-26
Abstract: Articles of electrically insulating material of a high silica content are manufactured by feeding a raw material, e.g. quartz or sand, to and through a zone in which it is melted and moulded, fresh granular raw material being continuously supplied to the surface of the molten material in the zone at such a rate that the thickness of the raw material on the surface of the melt does not substantially exceed the grain size of the material, and the rate of continuous withdrawal of the moulded material regulated to equal the rate of feed.  Quartz or sand is fed into a heated quartz trough 3 surrounded by an insulating jacket 4.  The material is fed from the trough into a rotating funnel 5 in a totally enclosed furnace the lower half of which is adapted to be cooled.  The batch is then fed on to the surface of a melt 13 in a crucible 7.  The crucible 7 has a shaped aperture 8 in its base with which a shaping tool 6 co-operates.  Both the crucible and the shaping tool are electrically heated (either by resistance or induction) and either the tool 6 or both may be subjected to ultrasonic vibrations. To accurately control the size and shape of the moulded articles, the shaping tool is adjustable vertically and in a direction transverse to its axis.  The crucible and tool are made of heat-resistant metals such as molybdenum. <PICT:1065396/C1/1> To prevent undue evaporation, the feeding and melting is carried out in an inert atmosphere.  Various embodiments for the drawing of tubing, rods, bars or strips are shown.

Title: Process for graphitizing residues of the thermal decomposition of carbonaceous materials
Filed: 1957-08-23
Abstract: <PICT:0874434/III/1> In the graphitisation of residues of the thermal decomposition of carbonaceous materials in a furnace lined with refractory carbon-containing material at all parts subjected to the highest temperatures and having preheating, heating, and cooling zones through which a coherent charge of the residue material gravitates, the effluent gas from the preheating zone is recycled to the cooling zone and hot combustible gases having a reducing action, i.e. containing only CO and H2 apart from N2, are introduced directly into the heating zone at at least 1600 DEG C., the combustible gases having been obtained by reaction of CO2 and/or H2O with carbonaceous fuel in a gas producer at at least 1600 DEG C.  Fuel and CO2 and H2O are introduced tangentially into cyclone gas producer 4 through 5, 6 and slag is removed through device 13.  The gases enter the refractory furnace, lined in the hottest parts with carbon, graphite, or silicon carbide, and mix with the gases rising from the cooling zone 3.  The gas mixture rises through heating zone 2 and preheating zone 1 countercurrent to the carbonaceous charge entering through lock 11, and is withdrawn through 7. Water-cooled tubes may be provided on, or in, the walls, and alumina or zirconia may then be added intermittently to the fuel fed to the producer, to form a fused coating on the tubes to reduce heat transfer.  The coking residues should not be degassed too completely, or pitch, or tar may be added to form a gas envelope round the particles in the preheating zone to prevent deposition of volatile ash constituents, e.g. SiS, SiO, metal vapours, and alkali metal compounds.  Otherwise, gas containing volatile ash constituents may be withdrawn from the preheating zone at 9, and passed, with steam, or CO2, through a reactive granular fuel, e.g. lignite coke, to deposit volatiles. The purified gas is returned to the preheating zone at 10.  The effluent gas from 7 is, after cooling and purification, and preferably drying, recycled to the cooling zone at 8.  Attack of the furnace walls may also be reduced by adjusting the producer to deposit some soot.  The effluent gas from the preheating zone may be used to preheat the fuel for the producer.  The preheating zone may be used for coking cokable constituents, in which case, if the methane content of the circulating gases rises, a portion is introduced into the preheating zone at a point where the charge is at at least 1200 DEG C., and any soot deposit from the gas producer is reduced to make up for the deposit of soot in the preheating zone. In Fig. 2 (not shown) where coking of cokable constituents is effected in the preheating zone and gas is recycled to the preheating zone, a slag-tap gas producer is used, which is fed with a portion of the material to be graphitised by-passed from the furnace.
