Abstract: 971,424. Toy vehicles. METTOY CO. Ltd. Sept. 24, 1963 [June 27, 1962], No. 24652/62. Heading A6S. A model vehicle has a spring acting on an axle as spring suspension for the wheels, and acting also on a plurality of closure members hinged to the body about different axes. The embodiment shows a U-shaped spring member 7 of a plastics material riveted on the top of a pillar 11 on a base member 6. The lower part 18 of said member 7 holds an axle shaft 16 downwards between lugs 14 while the upper part 12 presses against the end 13 of a bonnet 3 which may be lifted and is held against return by passing over a dead-centre. When the front of the body of the vehicle is pressed downwards a column 8 on the spring member 7 is forced through a hole in the upper part of said member to unlatch the bonnet. The upper part of the spring member has side elements 27 for similarly holding the doors 4 in open or closed positions through the medium of a lug 28 attached to the pivotal axes 26 of the doors 4. The boot of the car is similarly constructed but does not control pivotations of doors. Specification 945,178 is referred to.

Abstract: 507,273. Harvesting-machines. AKTIEBOLAGET WESTERASMASKINER. Aug. 23, 1938, No. 24821. Convention date, Feb. 25. [Class 6 (iii)] A sheafing and binding machine is provided with a crop gatherer in the form of a device carrying sweep arms this device being capable of being removed, and substituted by a reel. The sweeps are pivoted on a rotary frame 5 and are provided with guide arms 11 passing through a controlling ring 10. The frame 5 is driven from a gear-box 1 through a universal joint 2 and a telescopic shaft 3, 4, that passes through a bearing 8. The bearing 8 is vertically adjustable to vary the height of the sweeps and is carried by a toggle joint 6, 7. The control ring 10 is movably-connected with the upper bearing 8 and the gear-box 1 by ball joints 12, 13. To substitute the reel shown in Fig. 1, the ball joints 12, 13, are loosened and the pin 9 of the toggle joint 6, 7, removed : the sweep-gatherer with the bearing 8 and shaft 4 is then bodily removed from the machine. A support 17 for the reel shaft 14 is then connected to the link 6 by the pin 9, and a shaft 21 inserted in the driving sleeve in place of the shaft 4.

Title: Wobble body mechanism for converting reciprocal movement to rotary movement and viceversa

Filed: 1962-06-28
Abstract: 1,010,796. Inclined crank mechanism. B. A. DE WAERN. June 28, 1962 [Jan. 23, 1962], No. 24906/62. Heading F2K. [Also in Divisions F1] In an engine or compressor wherein a wobble body 45 on an inclined crank-pin 42 of a main shaft 43 is connected to a number of pistons 73, the non-rotatable wobble body is slidably anchored at its periphery to a second crankpin 100, of smaller inclination, which is rotated at the same speed as the shaft 43 by a gear train 105 ... 109. As shown a ball 112 sliding on the pin 100 is radially slidable between two projections, Fig. 4 (not shown), on the body 45. If the ratio of the two crank-pin inclinations is one half, the ball 112 may engage a partspherical socket on the body 45-i.e. no radial movement occurs. The wobble body 45 is located on the crank 42 by a thrust bearing flange 53. A flange 34 on the main shaft locates this shaft in the housing 1. Both crank-pins have offset counterbalance masses. In the twelve-cylinder four-stroke engine shown, six pistons on each side of the body 45 are connected thereto by respective ball-ended rods such as 66. Each piston has an end recess 79 adjacent an injection nozzle 81. A toothed rim 86 on the shaft 43 operates through a countershaft 88 to drive a coaxial valve-operating cam 91 at half speed. The cam actuates for each cylinder an air inlet valve such as 82 and an outlet valve such as 84. In a two-stroke engine, Fig. 8 (not shown), the valve operating cam rotates with the main shaft. In a compressor, Fig. 9 (not shown), the pistons are flat-topped, the fluid inlet and outlet valves being formed as thin flaps swinging against perforated discs in the cylinder end wall. Specifications 618,553, 633,088, 662,190 and 672,235 are referred to.

Title: Data store

Filed: 1973-05-24
Abstract: 1377459 Data storage DIEHL 24 May 1973 [2 June 1972] 24912/73 Heading G4C Groups of shift registers 1 (Fig. 1) are stepped by logic circuitry 6 at a first higher frequency T when address and data bits A, I are present and at a second lower frequency when no information is present. The shift registers preferably comprise MOS integrated circuits. As described each group comprises five shift registers, each storing 64 words of 8 bits, connected to a counter 5 incremented with the stepping of each word. Timing- pulses at the first frequency are fed via a divider (7, Fig. 2, not shown) to derive pulses at the second frequency F. Since the address bits (A) applied to an OR gate (8) are synchronized with the timing pulses (T) the OR gate enables an AND gate (9) at the higher frequency when the address bits are present so that the selected group of registers is stepped at the higher frequency. The AND gate is enabled at the lower frequency (F) (also applied to the OR gate) when the addresses are absent.  Pulses at a higher frequency than the frequency T may be utilized during a search phase.

IPC: C10G1/08
Filed: 1932-09-08
Abstract: Iodine compounds of silver, copper, titanium, tin, manganese, nickel, or cobalt are used as catalysts in the heat treatment with hydrogenating gases of distillable carbonaceous materials.  The catalysts may be employed with the addition of compounds of metals of Groups 2--8 of the periodic system particularly oxides, hydroxides, or sulphides of the metals of Groups 5 and 6 or compounds of copper, silver, zinc, tin, cadmium, manganese, uranium, rhenium, nickel, cobalt, lithium, magnesium, aluminium, or silicon.  Nitrides, phosphides, borides, arsenides, and selenides also form suitable additions.  Carriers and dispersing agents may also be used, e.g. active carbon, silica gel, pumice stone, or porous sherds of burned fire clay.  The catalyst may be employed in a colloidal state. Middle oil vapours are passed at 440 DEG  C. and 200 atmospheres pressure with hydrogen over a mixture of tungsten sulphide with copper or tin iodides.  The product contains 60 per cent of benzine having a high anti-knock ratio. Aromatic hydrocarbons are similarly obtained by treating benzines at 550 DEG  C. in presence of a catalyst comprising molybdic acid, zinc oxide, and silver, titanium, or nickel iodides.  Pit coal mixed with heavy oil is similarly treated in presence of tin iodate.  The said treatment with hydrogenating gases includes destructive hydrogenation and the removal of sulphur and oxygen containing impurities from hydrocarbons and the hydrogenation of p  unsaturated hydrocarbons to form aromatic and hydroaromatic hydrocarbons.ALSO:Iodine compounds of silver, copper, titanium, tin, manganese, nickel or cobalt are used as catalysts in the production of hydrocarbons by treating organic compounds containing oxygen or sulphur, e.g. phenol or cresols, with hydrogenating gases.  The catalysts may be employed with the addition of compounds of metals of Groups 2--8 of the periodic system particularly oxides, hydroxides, or sulphides of the metals of Groups 5 and 6 or compounds of copper, silver, zinc, tin, cadmium, manganese, uranium, rhenium, nickel, cobalt, lithium, magnesium, aluminium, or silicon.

Title: Separation of chlorhydrines from hydrochloric acid solution
IPC: C07C29/66
Filed: 1935-09-09
Abstract: Chlorhydrins are separated from their crude solutions containing hydrochloric acid by neutralizing the acid with ammonia or ammonium salts of weak volatile acids, and then distilling off the chlorhydrin.  Before the distillation, the neutralized solution may be saturated with ammonium chloride, and during the distillation any liberated acid may be neutralized by further addition of ammonia. After the removal of the chlorhydrin, ammonium chloride is crystallized, and the mother liquor may be evaporated to dryness and purified by extraction of the impurities by means of a solvent such as alcohol or by heating to insolubilize the impurities after which the salt is recrystallized.ALSO:Ammonium chloride is obtained by neutralizing with ammonia or an ammonium salt of a weak, volatile acid the reaction mixture containing chlorhydrin and hydrochloric acid which is produced by reaction of an olefine with chlorine and water, the chlorhydrin being then distilled off.  Before the distillation, the solution may be saturated with ammonium chloride, and during the distillation any acid liberated may be neutralized by further addition of ammonia.  After the distillation, ammonium chloride is crystallized, and the mother liquor may be evaporated to dryness and purified by extraction of the impurities with a solvent such as alcohol, or by heating to insolubilize the impurities, after which the salt is recrystallized.
