Filed: 1973-03-07
Abstract: 1427972 Metallizing ceramic with gold B R SMITH 7 March 1973 [8 March 1972 27 April 1972] 11129/73 Heading C7D A ceramic is metallized by coating with a powder mixture of gold and cuprous and/or cupric oxide in an organic binder free from glass frit and firing. The preferred coating composition contains 0.1-7% cuprous and/or cupric oxide, 93-99.9% gold, both based on the total oxide plus gold and 10-95% organic binder based on the total weight. Alternatively the coating composition contains 0.1-7% cuprous and/or cupric oxide, 78-99.89% gold, 0.01-15% Cdo all based on the total oxide plus gold and 10-95% organic binder based on the total weight. The copper oxide and Cdo powder are milled to < 1 micron and the gold powder is 2-5 microns. The organic binder may be beta terpinal, ethyl cellulose, pine oil or methyl cellulose the coating is applied to the ceramic e.g. Al 2 O 3  by silk screening printing, brushing or hand dipping. The firing is at 900-1063‹C for Cdo free coatings and 850-1063‹C for Cdo containing coatings. The coating has a high bond strength and lower electrical resistivity than coatings containing glass frit.

Patent GB-1087163-A (GB)
Title: Production of ketene
IPC: C07C45/89
Filed: 1965-03-17
Abstract: Ketene is produced by vapour phase catalytic pyrolysis of acetic acid in the presence of 1-15% by weight of the acetic acid vapour of water, introduced into the pyrolysis zone together with the acetic acid.  The water may be added prior to or after the vaporization of the acetic acid and may be in liquid or vapour form.  Acetic anhydride may also be added to the feed to suppress anhydride formation during the pyrolysis.  The reaction is carried out between 625 DEG  and 750 DEG  C. and at a pressure between atmospheric and 20 p.s.i.  A suitable catalyst is methyl phosphate.  The vapours are allowed to remain in the reactor for between 0.01 and 5.0 seconds and ammonia may be added to the issuing mixture to neutralize the catalyst and prevent combination of the ketene with the acetic acid or water.  The ketene is separated from the mixture by cooling.

Patent GB-804311-A (GB)
Title: Uranium hexachloride and processes of producing the same
IPC: C01G43/08
Filed: 1944-06-20
Abstract: Uranium hexachloride is prepared by heating uranium pentachloride under sub-atmospheric pressure to a temperature between 80 DEG  and 180 DEG  C. whereby the uranium pentachloride is split into uranium tetrachloride and hexachloride, the latter subliming on to a cooled surface.  As shown in the Figure, a molecular still consists of an outer wall 11 the lower portion of which is contained in a sand bath 19, and an inner vessel 18 which is filled with liquid oxygen.  The space between the two vessels is evacuated through line 21 to a pressure between 10-6 and 10-3 mm. of mercury.  The charge of uranium pentachloride 17 is placed in the bottom <PICT:0804311/III/1> of the vessel 16 and after reduction of pressure the sand bath is heated to a temperature between 80 DEG  and 180 DEG  C. and the wall of the vessel 18 is cooled to a temperature below 10 DEG  C. by means of the liquid oxygen contained therein.  Uranium hexachloride sublimes and condenses on the wall 18 and the residue consists of uranium tetrachloride.  The product UCl6 is a finely crystalline iridescent green substance having a vapour pressure of about 1.3 mm. of mercury at a 100 DEG  C.; it is extremely hydroscopic and unstable in ordinary atmospheres, wherein it decomposes to UO2Cl2.  It is therefore necessary that the still be opened in an inert dry atmosphere.  Specification 800,731 is referred to.

Patent GB-654698-A (GB)
Title: Improved moulding compositions
Inventor: WILLIAMS JAMES HAROLD
IPC: C08K3/38
Filed: 1948-04-30
Abstract: A phenol-aldehyde moulding composition is produced by admixing a novolac, hexamethylene tetramine and an alkaline earth metal borate in amount from 1 to 20 per cent by weight of the novolac and hexamethylene tetramine.  Magnesium, calcium or barium borates may be used, calcium metaborate being preferred.  They are more effective in admixture with orthoboric acid.  The condensation product may be prepared by reacting phenol, m-cresol, resorcinol or 3 : 5-xylenol or mixtures of these, with formaldehyde or furfural, the ratio of aldehyde to phenol being not greater than 1 : 1.  Incorporation of an alkali, e.g. an alkaline earth metal oxide, prevents sticking of mouldings in the mould.  An example compares the properties of moulding compositions comprising a novolak, hexamethylene tetramine, wood - flour, calcium hydroxide, stearic acid, nigrosine with and without calcium metaborate. Other fillers mentioned are paper, cotton, mica, string, dried fabric and asbestos.  The compositions may be prepared in aqueous or alcoholic suspension followed by drying.  Specification 646,093 is referred to.  The Provisional Specification refers to paraformaldehyde and polyoxymethylene as alternatives to hexamethylene tetramine.

Title: Improvements in and relating to clutch-brake mechanism
IPC: F16D55/00
Filed: 1951-05-22
Abstract: 688,247. Magnetic fluid clutch-brake combinations. BRITISH THOMSON-HOUSTON CO., Ltd. May 22, 1951 [June 2, 1950], No. 11934/51. Class 80 (ii). [Also in Group XXXIV] A combined clutch and brake employing a magnetically susceptible fluid, preferably a mixture of powdered iron and oil, comprises a; driven rotor 9 of magnetic material, a fixed: permanent-magnet brake 13, a driving rotor 20, 21, 22, and a fixed coil 23. Energisation of coil 23 overrides the field of magnet 13 so that iron powder which was concentrated in the gap between the rotor 9 and magnet 13, thereby braking the rotor, is drawn around the periphery of, and through holes 27 in, the rotor 9 to couple the driving and driven rotors. The annular magnet 13 (which may be replaced by an electromagnet) is surrounded by a non-magnetic ring 14 and a magnetic ring 15 secured to a non- magnetic housing 1. The housing has a magnetic cover 3 carrying the coil 23 which is arranged between inner and outer magnetic rings 20, 22 of the driving rotor, the spacer ring 21 being non-magnetic. The time delay between clutch and brake operation is predetermined by the clearance around the rotor 9 and by the size and number of the holes 27. Preferably excitation is by direct current, but alternating current, particularly of the higher frequencies, may be employed provided the magnetic parts are laminated. In a modification a magnetic rotor is keyed for limited axial movement on a driven shaft and is moved to clutching or braking position by the corresponding field, the gaps being filled with a magnetic fluid. Reference has been directed by the Comptroller to Specifications 649,553 and 686,141.

When hydraulic control-valves A, B are set in a first position a screw O is driven so that refuse dumped into the rear end of a refuse vehicle is moved forwards. With an alternative setting of the valves for unloading the refuse a latch K which retains a rear wall N of the vehicle is released by an hydraulic cylinder H. After the hydraulic pressure has risen the cylinder H is operated through a relief valve E to raise the rear wall N about its upper edge. Subsequently, when the pressure has risen still further, an hydraulic cylinder G which raises the front of the vehicle body is operated. Finally fluid passes through a relief valve D to an hydraulic screw-driving motor L in such a manner that the screw discharges the refuse. Return of the valves A, B to their first position allows return of the hydraulic fluid to a reservoir through non-return valves C, F and all the parts return to their initial positions.
