Title: Improvements in the production of alkyl and cycloalkyl dihaloborines
IPC: C07F5/02
Filed: 1959-03-10
Abstract: Alkyl and cycloalkyl-dichloroborines and dibromoborines and substitution products thereof are prepared by reacting hydrogen, boron trichloride or tribromide, and an aliphatic or cycloaliphatic hydrocarbon having at least one centre of ethylenic unsaturation, or a substitution product of such a hydrocarbon in which the substituent or substituents are attached to carbon atoms at least one removed from the double bond, the reaction being carried out in the gas phase and at a temperature of 300 DEG -600 DEG  C. in the presence of an asbestos catalyst.  The rate of flow should be so correlated with temperature that the product is removed from the reaction zone before it decomposes, residence times of 0,50 to 0,95 minute being preferred at optimum temperatures of 400 DEG -500 DEG  C.  The dihaloborine product may be recovered by fractional distillation. Halogen-substituted hydrocarbons in which the halogen corresponds to that of the boron trihalide may be used as starting materials to produce haloalkyldihaloborines. The dihaloborines may be used as igniters for liquid, propellants and as intermediates for borazoles boronic acids and boroxines. In an example, ethyldichloroborine is reacted with aniline to form B, B1, B11-triethyl-N, N1, N11-triphenylborazole.

Title: Sintering method
IPC: B22F3/10
Filed: 1963-03-01
Abstract: In a process of vacuum sintering a metal powder such as Cr, a material such as a ceramic e.g. MgO, which has a lower vapour pressure than the metal and forms a porous coating on the metal during sintering, is added to the metal and the mixture is vacuum sintered at a pressure which is lower than the vapour pressure of the metal and high than the vapour pressure of the additive at the sintering temperature.  Other metals which may be sintered are Mn, Ag, Al, Be, Fe, Cu, Ni, Au, Ti, V, Zr, Pt, Re, Mo, Nb, Ta and W and other materials added may be SiO2, B, Si, Al2O3, ZrO2, BeO ThO2, C. Alloying may also be effected during sintering and in the example 6% MgO and 0.5% Ti are added to Cr powder and sintered.  The powders are all -325 mesh (20-40 microns) and in general the absolute pressure of sintering is 0.1 to 0.001 of the vapour pressure of the material being sintered The sintered body may be hot pressed to increase the density.

Title: Suspension system in combination with hydraulic braking mechanisms for motor vehicles
IPC: B60T8/00
Filed: 1973-02-21
Abstract: 1394658 Anti - locking brake systems ROBERT BOSCH GmbH 21 Feb 1973 [22 Feb 1972] 8418/73 Heading F2F A motor vehicle has an anti-locking brake system integrated with a hydropneumatic suspension system, the suspension system comprising a pump 8, an accumulator 9, a reservoir 11, a regulating valve 7 and respective suspension elements 3, 4 on wheels 1, 2, and the brake system comprising respective brake pressure reducers 21, 22 in brake lines 17, 18 between a master cylinder 16 and wheel cylinders 19, 20 and respective pairs of solenoid valves 23, 24 and 25, 26 operable by sensors 27, 28 on wheels 1, 2; each reducer 21 (22) comprises a valve 29 (30) actuable by a piston member 31 (32) which has a working chamber 33 (34) beneath it, which working chamber 33 (34) is normally connected to a respective element 3 (4) by way of a line 33<SP>1</SP> (34<SP>1</SP>) and a solenoid valve 23 (26). In the event of wheel lock at a wheel, e.g. 1, being detected the respective solenoid valves 23, 24 are switched over so that the working chamber 33 is sealed off from element 3 and connected to reservoir 11 via a discharge line 15. Thus the piston member 31 moves downwardly to close valve 29 and increase the volume of brake line 17 to relieve pressure in wheel cylinder 19. When the wheel rotates again the valves 23, 24 and reducer 21 return to their original positions. Should pump 8 or accumulator 9 be eliminated a relief valve 12 ensures that elements 3, 4 cannot be emptied and this ensures pressure in chambers 33, 34 when the anti-locking arrangement is not working to stop unintended rupture of communication between the master cylinder 16 and wheel cylinders 19, 20. The arrangement may appropriately be used in a two-circuit four-wheel anti-locking system where it avoids duplication of accumulators and pumps.

Title: Electric clocks
IPC: H02P3/08
Filed: 1973-02-21
Abstract: 1397667 Clocks SONY CORP 21 Feb 1973 [26 Feb 1972] 8431/72 Heading G3T A digital electric clock comprises a D.C. motor 21 which is supplied intermittently from a cell 51, Fig. 4, via a semi-conductor switch 50, the latter switch being controllable by a magnet-sensitive  switch, e.g. a reed switch, 22, the control magnet 38 of the switch 22 being displaceable by rotation of the motor 21 so that when the switch 50 is closed by a pulse at electrode b, the motor is energized and displaces the magnet to hold the switches 22 and 50 closed until the motor has advanced the time indicating means 13-15 by one digit only. After this advancement, a cam 42 driven by the motor displaces arm 39 and thus the magnet 38 away from the switch 22 which is thereby opened, opening the switch 50 to stop the motor. The motor is thus energized only during advance of the display drums, which is stated to conserve battery power. The drums 13-15 show hours and tens and units of minutes, the drums being coupled by pins and pin wheels and the drum 15 carrying a ratchet wheel 19 driven by a pawl (37), Fig.2 (not shown) on an arm 35 which is actuated every minute by a cam 23 driven by the motor. The pulses which close the switch 50 once each minute are derived from a quartz oscillator (55), Fig.5 (not shown) via frequency dividers (56,57). The minute drum 15 carries a heart cam 60 so that depression of a pin 62 resets this drum to zero, the count held in the divider (57) being zeroed at the same time. An arrangement is also envisaged in which both dividers and all the drums may be set to zero simultaneously.

Title: A process for the manufacture and production of sodium hydrosulphite and pure zinc oxide or pure zinc carbonate
IPC: C01G9/02
Filed: 1930-03-17
Abstract: To the aqueous reaction mixtures of equivalent quantities of zinc dust and sulphur dioxide is added at least 1 per cent (by weight of the zinc dust employed) of zinc oxide, zinc dust, or zinc carbonate, the resulting solution of zinc hydrosulphite being filtered, and then treated with an excess of caustic soda or sodium carbonate, in which latter case the zinc carbonate formed is heated to form zinc oxide. The excess zinc or zinc compound may be added before, during or after the main reaction, or a little sodium hydroxide or carbonate may be added before filtration of the solution obtained from equivalent quantities of zinc dust and sulphur dioxide.  The quantity of sulphur dioxide employed in practice is usually slightly in excess of the quantity theoretically required, since the zinc dust usually contains impurities which consume some sulphur dioxide.  Examples of the process are given.
