Title: Improvements relating to refractory linings for chambers for degasifying metals
IPC: F27D1/16
Filed: 1963-02-01
Abstract: The durability of refractory linings of vacuum chambers for degasifying metals is increased by covering with an alumina-silica coating which is viscous at operating temperatures.  The coating may also contain fluospar and magnesia. The constituents of the coating may be applied to the lining or to a layer of sand on the lining, the coating forming when the chamber is heated. Alternatively, slag free metal can be covered with a slag formed from the constituents, only the metal being drawn off from the chamber leaving the slag as the coating.

Title: Method of Filtering a Gaseous Medium and means therefor
IPC: F15B21/12
Filed: 1967-01-27
Abstract: 1,179,432. Gas filter. HART-CARTER CO. 27 Jan., 1967 [15 Aug., 1966], No. 4268/67. Heading B1T. Inward flow gas filtering element 34 below tube plate 22 dividing housing 10 are cleaned by (i) reversing gas flow through an element to tauten it by distention and then (ii) producing in the element a shock wave e.g. produced by a sudden jet of high pressure gas from a conduit 206. As shown conduit, 206 is located inside nozzle 132 and the shock wave, of duration 0.015 seconds, is delivered half way through the 1 second reverse flow period. The nozzle assembly is rotated by a motor 70, low pressure air or filtered gas is delivered by a fan 40 to conduit 44 and high pressure gas (80 p.s.i.g.) is supplied to conduit 104, which conduits are fixed and connected to the rotating parts by seals 78, 86, 110. Part of the high pressure gas is bled off through a jet nozzle 176 across an annular cavity 180 into a pneumatic pilot valve 186, and as the assembly rotates the bleed stream is interrupted by a series of thin, fixed rods 204. This causes valve 186 to open (Figs. 7, 8 not shown) which opens a pneumatic valve 160 controlling the main high pressure gas stream, which flows from conduits 116, 154 through a surge tank 156, valve 160 to conduit 206 and thence through holes 210 into the filtering elements. The pneumatic circuit formed by valves 186, 160 restores itself to the closed position as soon as a rod 204 is passed, there being one rod 204 for each filtering element or aperture in plate 22. The main nozzle 132 makes a sliding seal with plate 22 by means of a felt gasket 142, and may be sufficiently wide that its leading edge clears one plate aperture 32 as its trailing edge leaves the preceding one. The elements 34, Fig. 1 are flat, internally supported felt bags, and dust blown from their outer surfaces is removed through a lower rotary air lock from the filter housing. Dusty gas enters the housing tangentially at 28, a fan being located upstream or downstream of the filter. Two filters may be operated in series or parallel. Specification No. 1,179,433 is referred to.

Abstract: 1496085 Anti-theft devices for vehicles NEIMAN SA 31 Jan 1975 [6 Feb 1974] 4328/75 Heading E2A [Also in Divisions B7 and Fl] In a vehicle having an i.c. engine (e.g. a diesel) a lock is operable by a key 8 to move a bolt 32 to engage a steering column, and to simultaneously actuate a transmission system acting on a control lever 55 of a fuel injection pump 60 for the engine. In the arrangement illustrated in Figures 1, 3, 4 the lock comprises a rotor 2 which is driven by the key 8 to drive a plate 34-the plate 34 drives, via a pin 35, a rotor 37 of a electric starting switch and the bolt 32 and also via a pin 72 a pinion 39 freely rotatable on rotor 2. The pinion 39 meshes with a rack 40 which acts via the transmission system to move the lever 55. As shown the transmission system comprises a bowden cable 43. In the embodiment of Figure 6 (not shown) the system comprises a rigid rod (62) and a bell-crank (63). In the embodiment of Figure 7 (not shown) a hydraulic or pneumatic transmission system is utilised. In the modification of Figure 5 (not shown) a drum (49) replaces the rack and pinion and the transmission system comprises a flexible cable (46) wound round the drum. The pin 72 and slot 73 constitute a lost motion connection to ensure that the bolt 32 is moved to an unlocking position before the pump 60 is opened and that the pump 60 is closed before the bolt is moved to a locking position.

Title: Improvements in processes for vulcanizing rubber and products obtained thereby
IPC: C08K5/00
Filed: 1922-02-15
Abstract: 177,493. Cadwell, S. M. March 25, 1921, [Convention date]. Vulcanizating-compositions.-The vulcanization of rubber &c. is accelerated bv the addition of a substance containing the radical R-#C-S-M where M represents a salt-forming element or group or hydrogen, or a radical S-#C-R, or a radical #C-R, X represents a bivalent element or radical, and R represents any element except nitrogen, this exception however being absent when M represents #C-R. Numerous substances falling within this category are specified. For vulcanizing at ordinary temperatures with substances in which M represents a metal the preferred metals are zinc and mercury; at higher temperatures, the preferred metals are zinc, mercury, lead, cadmium, copper, arsenic, manganese. If other metals be employed one of these metals should be present in the mixing in some form. Bases, as sodium hydroxide accelerate the action of these substances. Amines may also be added, the greatest effect in the case of aliphatic amines being produced when a half molecular weight of amine on the basis of the carbon bisulphide content of the thiol salt is used. An excess of aliphatic amine tends to retard vulcanization. The greater the amount of primary aromatic amine, the greater the acceleration. In an example, 100 parts of rubber, 10 parts of zinc oxide, 4 parts of zinc butyl xanthogenate, 1 part of sulphur, and 2 parts of toluidine is mixed as usual and allowed to stand for several days. For a cement, 100 parts of rubber, 10 parts of zinc oxide, and 6 parts of zinc butyl xanthogenate are mixed with 800 parts of benzol: and 100 parts of rubber, 10 parts of zinc oxide, 6 parts of sulphur and 6 parts of paratoluidine are mixed with 800 parts of benzol. On mixing these solutions in equal proportions, rubber is obtained which vulcanizes in 24-48 hours at room temperature, or more quickly at higher temperature- With substances in which M represents S-#C-R, the time of vulcanization is generally longer, and there is less danger of prevulcanization in the mill. As an example, 100 parts of rubber, 10 parts of zinc oxide, 3 parts of sulphur, and 2 parts of o normal butyl thiocarbonic acid disulphide are mixed and vulcanized in 10 minutes at steam pressure of 401b. per sq. in. Substances in which M represents #C-R are specially adapted for hot vulcanization, and there is no tendency to prevulcanization. In an example, 100 parts of rubber, 10 parts of zinc oxide, 3 parts of sulphur and 1-10th part of diphenyldimethylthiuram sulphide are mixed as usual and vulcanized in 10 minutes at 40lb. steam pressure.

Abstract: 910,905. Electric analogue calculating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 27, 1961 [Feb. 11, 1960], No. 4895/60. Class 37. With contacts 4 and 9 closed a differentialselsyn 1 receives signals from two selsyns 2, 3 and positions its rotor in accordance with their sum. Contacts 4 and 9 are then opened and a follow-up loop, comprising selsyns 5, 6, comparator A-B and a motor, is energized, by means not shown, to cause the rotor of selsyn 3 to assume the angular position of the rotor of the differential selsyn. If contacts 4 and 9 are then again closed the differential-selsyn will therefore advance a further amount determined by the setting of selsyn 2. Thus the differential-selsyn, together with the followup loop, accumulate signals successively received from the selsyn 2. If the selsyn 2 is kept in the same position this will result in a step-by-step motion of a shaft 7 of the followup loop.
