Title: Improvements in or relating to refractory materials
Filed: 1965-07-19
Abstract: A refractory batch contains: (a) a chromium compd. which upon firing forms Cr2O3 in an amount up to 0.28% wt. of the fired batch, (b) a finely divided silicon compound added to the batch as a separate constituent having a specific surface of at least 1000 cm.2/g. which forms SiO2 in an amount yielding 0.60.-1.10% wt. total SiO2 in the fired batch and (c) the balance being a magnesium which upon firing yields MgO and contains not more than 0.6% SiO2 and not more than 2% impurities on the fired basis.  The G and Si compounds are in such amounts that the weight ratio SiO2:Cr2O3 in the fired batch is at least 4 : 1.  The batch can be fired, e.g. at at least 1600 DEG  C., to form a dense magensia.  The firing can be carried out in two stages, the product from the first stage firing, e.g. 700-1200 DEG C., being compacted before the second firing.  The magnesium compound can be MgO, MgCO3 or Mg(OH)2 which can contain SiO2, CaO, Fe2O3 and Al2O3.  The chromium compound can be chromic acid, alkali metal chromate or dichromate, magnesium chromate, chromite, chrome ore, chromium metal, chromium sulphate or Cr2O3, and may be added as a powder or in solution. The silicon compound can be volatilized SiO2 containing Fe, Mg and Al impurities.

Title: Improvements in or relating to liquid operated jacks
IPC: B60S9/12
Filed: 1928-10-23
Abstract: 324,385. Bridgens, W. R. Oct. 23, 1928. Stands or supports for vehicles. - A fluid-pressure jack comprises two hollow telescopic plungers normally spring- retained in a cylinder, the liquid being admitted to and out off from the inner plunger by a valve held open by the, outer plunger when closed, so that the full outward movement of the inner plunger is assured before the outer plunger moves and allows the valve to close. A cylinder 1 carried by the vehicle contains two hollow plungers 6, 13 the outer of which is held raised by a compression spring 7. When fluid under pressure enters at 3 it acts on the inner piston 22 which is forced down against the action of a tension spring 20. At the end of the travel the fluid acts on a piston 9, 10 and the plunger 6 is depressed to raise the vehicle. A valve 28, 29 which admits fluid to the piston 22 is normally held open by the contact of the cover 2 with the stem 29 as shown. When the piston 9, 10 begins to descend the valves closes and the full pressure of the liquid acts on this piston. The foot 16 is secured to the inner plunger 13.

Phase-modulated data is amplitude-modulated to provide a synchronizing signal at the receiver in a data transmission system. The system described has two binary data inputs at A, B which feed relays R A , R B . Unit T produces clock pulses at bit frequency, adjacent pulses having different amplitudes, as indicated. The clock pulses pass to contacts r A , r B  both direct and via inverter U. The resultant pulse trains indicate the sign of the bit by their polarity, adjacent pulses having different amplitudes. After filtering at F A , F B  and modulating at M A , M B  with quadrature carriers, the signals are combined at S to give a phasemodulated data signal in which the phase rela. tive to that during the previous, clock period determines'the combination of bits on the input channels and in which the amplitude provides a sync. signal. At the receiver the phase-modulated signals are detected as indicated, and the amplitude modulation, by' way of rectifier G, excites a ringing circuit which feeds frequency doubler FV. The output of this unit is shaped at JF to provide clock pulses which operate. switches AS A <SP>1</SP>, AS B <SP>1</SP> ,  so that the original data pulse trains appear at A<SP>1</SP>, B<SP>1</SP>.

Title: Conductivity cell
Inventor: ESTELLE WEEMS E
Filed: 1959-09-08
Abstract: 874,923. Detecting impurities in fluids. McNAB Inc. Sept. 8, 1959, No. 30658/59. Class 37. An electrode structure for a conductivity cell comprises three coaxial disc electrodes 9, 19, 29, the outer electrodes 9, 29 being connected electrically to the support 1 for the structure and the central electrode 19 being insulated therefrom by a sleeve 21 of insulating material. The faces of the electrodes are coated with platinum and the central electrode 29 may be made of titanium. The lead 39 for the electrode 19 passes through a liquidtight seal provided by a grommet 43 compressed between a washer 41 and a retaining screw 45. The lead is secured to the electrode by means of a set-screw 51. The portion of the support 1 on the side of the seal remote from the electrodes serves as a housing for a temperature compensating thermistor 33. Heat transfer between the thermistor and the body of the structure is provided by a silicone oil bath 35 surrounding the thermistor. In use the electrodes project through a fitting into a liquidflow conduit, for example on a ship to detect the salt concentration in the water flowing therethrough. In a modification, Fig. 4 (not shown), the outer electrodes are formed integrally with the support member, instead of being secured thereto by the bolt 15, and the central electrode is made in two parts so that it can be fitted around the stem joining the outer electrodes. The support houses a temperature-compensating thermistor which, however, in this embodiment is encased in an epoxy-resin block having good heat-conducting properties. To prevent conduction between the central electrode and the conduit, the cylindrical peripheral surface of the central electrode may be given an insulating coating as may also the inner surface of the conduit where it is adjacent the electrodes.

Title: Process for making cellular polyethylene articles
IPC: B29C44/50
Filed: 1957-10-08
Abstract: <FORM:0822425/IV (a)/1> A process for making polyethylene foam comprises forming under pressure a flowable composition comprising essentially molten polyethylene having a volatile organic fluid as a foaming agent uniformly dispersed throughout, feeding the composition to a treating zone and subjecting the composition under pressure to ionizing radiations in amount sufficient to bring about an increase in resistance to flow of the polyethylene at a temperature of 100 DEG C. and insufficient to prevent appreciable flow of the polyethylene at said temperature and thereafter extruding the composition into a zone of lower pressure sufficient to cause expansion of the extruded material with resultant formation of a cellular body.  As ionizing radiation beta-rays, gamma-rays, X-rays, neutrons or accelerated electrons are mentioned.  The polyethylene preferably has a molecular weight of 4000 or above.  As foaming agents tetramethylmethane, monochlorodifluoromethane, monochlorotrifluoromethane, dichlorodifluoromethane or dichlorochlorotetrafluoroethane or mixtures of these are suitable.  Finely divided inert materials such as calcium silicate, barium sulphate or silica are also advantageously incorporated with the polyethylene to initiate the formation of cells.  The extrusion can be effected at 90 DEG  to 220 DEG  C.  In one method, polythene of molecular weight 30,000 is placed in cylinder 2 (Fig. 1) with frangible disc 5.  The volatile fluid is added and plunger 6 is inserted followed by cover-plate 7. The jackets 3 and 10 are supplied with heated heat transfer material and then a liquid such as glycol or glycerine or a gas such as nitrogen is pumped into inlet 8 whereby disc 5 is ruptured, and the gel is forced through the constricted passage of head 9 past window 12 from a source of ionising radiation 13 and into the atmosphere, forming a cellular product.  A continuous process is also described.
