Title: Improvements relating to coating metals with copper
IPC: C23C18/54
Filed: 1954-12-09
Abstract: A metallic surface, e.g. of a silver mirror, is coated with copper by being contacted with a copper salt solution and a metal powder suspension, one or both of which contain phosphoric acids, and/or one or more organic hydroxy acids, e.g. citric, malic, and tartaric acids.  The sulphate is used as the copper salt, and zinc and cadmium powder may be used in the suspension.  Additions which may be made to the solution and/or the suspension are (i) an p  alcohol, e.g. mannitol, (ii) a salt of the metal powder, e.g. cadmium sulphate in the case of cadmium, and (iii) a reducing agent, e.g. sodium hypophosphite.  The suspension may also contain a dispersing agent, e.g. gelatine, agar-agar, or a cellulose ester or derivative such as sodium carboxymethyl cellulose.

Title: Improvements in or relating to noise protection circuits for television receivers
IPC: H04N5/21
Filed: 1962-09-19
Abstract: 985,589. Television; interference suppression. ADMIRAL CORPORATION. Sept. 19, 1962 [Sept. 22, 1961], No. 35739/62. Headings H4F and H4L. The invention relates to a transistorized television receiver circuit and is concerned with the elimination from the separated synchronizing pulses of fortuitous noise whose amplitude exceeds that of the synchronizing pulses by a predetermined amount. As shown, the negative-going composite signal is received at the base of the transistor video amplifier 25 and after amplification by this transistor and amplification and inversion by the further video amplifier 40, the composite signal is applied to the sync. separator stage 55 by way of the junction A. The noise signal which is to be eliminated appears (together with the composite signal) at the collector of video amplifier 25 and is passed by the biased diode 30 to "bottom" the normally " off " transistor switch 35, thus giving rise to negative-going " noise " pulses which over-cancel the corresponding noise pulses present in the composite signal at " A."

Title: Improvements in or relating to cylinder liners for internal combustion engines
Inventor: WOOLCOTT ARTHUR JOHN
IPC: C23C2/12
Filed: 1961-10-04
Abstract: Grey cast iron wet cylinder liners are coated on the outside surface with aluminium or aluminium alloy, to reduce the effect of cavitation erosion, by dipping the liner into molten aluminium or aluminium alloy at a temperature above the critical range for the iron (860-880 DEG C.) to allow the aluminium to alloy with the surface of the iron, followed immediately by quenching the liner below the critical range of the iron to favour formation of sorbitic iron and suppress the ferritic structure. Quenching is achieved by plunging the coated liner into a bath of aluminium or aluminium alloy at a temperature in the range 570-680  DEG C. In the case of grey iron compositions containing alloy constituents such as Cr and/or Mo it may be necessary to raise the first bath temperature by about 15  DEG C., the second bath temperature remaining constant.

Title: Production of esters of alkylboronic acids and dialkylborinic acids
IPC: C07F5/02
Filed: 1960-10-21
Abstract: Esters of boronic and borinic acids having the formula RnB(OR1)3-n, wherein R represents an alkyl radical having at least two carbon atoms which may be substituted by aryl groups or halogen atoms, n is 1 or 2, and R1 represents alkyl, cycloalkyl, alkoxyalkyl, aminoalkyl, alkylaminoalkyl, aryl, alkoxyaryl, aminoaryl or alkylaminoaryl or 2R1 represents alkylene when n is 1, are made by reacting an ester of a halogeno-boric acid having the formula XnB(OR1)3-n wherein X means a halogen, n and R1 are as above, with an olefin and an alkali metal or alkaline earth metal borohydride and recovering the ester formed. The olefines are those derived from radical R by splitting off a hydrogen atom and include olefines of the ethylene series, halo-olefines and arylolefines. Monofluoroboronic acid esters and difluoroborinic acid esters are suitable starting materials. Temperatures between -20 DEG C. and the decomposition point of the reactants or the boiling point of any solvent may be used, the optimum temperature lying between 30 and 100 DEG C.  The haloboric acid esters may be made in situ by introducing boron trihalide into a mixture of borohydride and boric acid ester in a solvent.  Thus the boronic or borinic acid esters may be made by reacting akali metal or alkaline earth metal borohydrides with boric acid esters B(OR1)3, alkyl ether addition compounds of boron trihalide and olefines. Esters of alkylboronic acid or dialkylborinic acids with alkanols, such as methanol, ethanol, propanol, butanol or amyl alcohol, can be converted into esters of higher boiling alcohols, alkoxyalkyl alcohols or aminoalcohols by heating the esters of said alkanols with said higher-boiling alcohols, if necessary in a vacuum, to temperatures between the boiling point of the lower alcohol and that of the higher boiling alcohol, until the alkanol bound in the ester is completely distilled off and recovering the desired ester.

Abstract: 1,009,533. Valves. ROBERTSHAW CONTROLS CO. Sept. 17, 1963 [Nov. 13, 1962], No. 36603/63. Heading F2V. [Also in Division G3] A relay valve for transmitting the higher of two pressures to an outlet comprises a housing having a first inlet 22, a second inlet leading to a port 42, by a passage 52, and an outlet passage 54. In the embodiment shown, the inlet 22 is connected to a constant pressure chamber 72 by a passage 48 and a valve 76, the chamber 72 being connected by passage 86 and recess 46 to a port 40. The two pressures at ports 40, 42 act on opposite sides of a diaphragm 50 whereby the diaphragm closes on either a seat 56 or a seat 58 to close the port 40 or 42 which is at the lower pressure. Fluid then flows from either the port 42 through slits in the diaphragm or from port 40 to the outlet. The constant pressure in chamber 72 is maintained by a stem 90 connected to a diaphragm 70 and loaded by a spring 94 to open the valve 76 when the pressure in chamber 72 falls below a predetermined level or the pressure on the diaphragm lifts the stem to open the chamber to exhaust if the pressure exceeds the predetermined level. If an outlet is required at the higher of two variable pressures, the valve 76 and chamber 72 are removed, and section 30 of the housing is rotated through 180 degrees to con - nect passage 48 directly to recess 46 and port 40. The relay may be used to position a valve in response to signal pressures, representing pressure, temperature or humidity.

Abstract: 619,477. Electromagneto. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Dec. 12, 1946, No. 36722. Convention date, Sept. 7, 1945. [Class 35] [Also in Group XXXVII] The electro-magnetic tripping device of an automatic circuit-breaker comprises a sealed tube movable with the core of the electromagnet, the tube containing means for delaying the tripping of the circuit-breaker and being arranged, to be held substantially stationary during the tripping movement of the core. The core assemblage 159 comprises a non- magnetic outer tube 167 and a non-magnetic sealed inner tube 169 containing oil, the tube 167 being secured to a magnetic core 171 which normally rests on a part 157 of the yoke 155. A core 175 is biassed by a spring 177 against a stop 179 on the tube 169, which normally rests on a main core 183 supported on an adjusting screw 185. A spring 193 surrounding the tube 167 is initially compressed between a flange 195 and projection 199 thereon. On a light overload, e.g. up to 700 per cent normal load current, the core 183 and tube 169 move upwards compressing a spring 187. By means of co-operating projections 197 and slots, the tube 167 is also moved, whereby a pin 173 thereon trips the circuit-breaker with a time delay produced by the flow of oil through an orifice 181 in the core 175 which remains stationary. On a medium overload, e.g. 700 per cent to 1000 per cent normal, the core 171 and tube 167 are moved rapidly upwards until arrested by the engagement, of the spring 193 -with the projections 197. Thereafter, the tubes 167, 169 move up under the joint action of cores 171, 183 to trip the circuit-breaker with a reduced delay. On overloads over 1000 per cent normal, the tube 167 and core 171 are moved up with sufficient force to compress the spring 193 and trip the breaker instantaneously without the time-delay device coming into effect.
