Title: Improvements in and relating to hydraulic rotary engines or pumps
IPC: F04C2/36
Filed: 1945-11-07
Abstract: 602,836. Rotary engines &c. BAGHUIS, L. H. Nov. 7, 1945, Nos. 29698 and 29699. Convention dates, July 21, 1942 and June 10, 1943. [Class 110 (ii)] A rotary hydraulic engine or pump comprises two concentric relatively rotatable members, the inner member having an even number of pistons and the outer member having an even number of cylindrical abutments housed in equally spaced pockets and rotating in equal directions about axes parallel to. the engine shaft, there being at least two abutments in the working space between adjacent pistons. The inner member 7 has inlet ports 19 and outlet ports 20 on either side of the pistons 12, which communicate with axial passages 18 and 21 respectively within the shaft 10. The periphery of each piston extends along a longer circular arc than the pocket 23 in which each abutment is housed. Each pocket has a local enlargement 26 forming a chamber which becomes filled with liquid exerting a balancing pressure on the abutment. The six abutments 13 are driven through gearing at twice the speed of the inner member 7 with respect to the outer member. Slots 22 are provided to facilitate escape of liquid trapped between a piston and an abutment recess. Alternatively, a clearance may be provided between the end faces of the pistons and the side walls of the recesses. In an alternative construction, the gears are eliminated by forming gear teeth on the inner member 7 and abutments 13, continuity of meshing being obtained by making the axial width of the pistons and abutment recesses less than that of the toothed surfaces. The pistons are formed as a separate member which is loosely mounted in a diametrical bore of the inner member 7. In a construction in which two or more units are mounted coaxially with common shafts for the inner members and abutments, the pistons and abutment recesses extend across the full width of the toothed surfaces, and continuity of meshing is provided by maintaining a suitable difference of phase between the units.

Title: Control switch for vehicle direction indicators
IPC: B60Q1/42
Filed: 1953-11-03
Abstract: 729,026. Mechanical switches, without quickaction. BELTRAME, A. Nov. 3, 1953, No. 30351/53. Class 38 (5) [Also in Group XXXVIII] A self-cancelling control switch for vehicle direction indicators (see Group XXXVIII) comprises a control lever 5 attached to a forked member 4 pivoted at 3 and having arranged between its branches the end of a beam 28 oscillatable about a pivot 27 and co-operating with spring means 33 (Figs. 2 and 4, not shown) tending to return it to its middle position, the other beam end co-operating with projections carried by a rotatable steering column (not shown). The reciprocal arrangement of the forked member 4 and beam 28 is such that, when the control lever is brought to either turn-indicating position, oscillation of the beam 28 by one of the projections on the steering column when turning is clear of the fork 4. On subsequent straightening of the vehicle, oscillation of the beam 28 returns the fork 4 to its middle inoperative position. The beam pivot 27 is carried by a support 25 displaceable against action of spring means 26 radially of the steering column towards the main pivot 3; this prevents hindrance to the steering movement should the beam 28 and a projection mutually jam. Contact wipers 16, 17, 18, 19, 20 and 21 are carried by the forked member 4, the underside of which is shown in Fig. 3. Contact wipers 16, 17, 18 and 19 are connected together at the top of member 4 by a bridge 22 (Fig. 1) and wipers 20 and 21 are similarly interconnected by a bridge 23. The wipers co-operate with fixed contacts 10, 11, 12, 13, 14 and 15 as follows. In the normal central position of the control lever 5, contacts 10, 11 and 12 are joined by wipers 20 and 21. On moving the lever 5 to the left, contacts 12 and 10 are bridged by wipers 20 and 21 and contacts 13, 15 and 11 are connected together by wipers 16, 17 and 19. On moving the control lever to the right, contacts 10 and 11 are bridged by wipers. 20 and 21, and contacts 15, 12 and 14 are connected together by wipers 16, 17 and 18. A spring-loaded ball 6 locates the three angular positions of the forked member 4 by snapping into and out of a notch in a portion 8 of the casing.
Patent GB-797578-A (GB)
Title: Cracking of oligomers of isobutene
IPC: C07C4/22
Filed: 1956-10-05
Abstract: Isobutene is prepared by cracking oligimers thereof in the presence of a magnesium silicate catalyst containing 1-20 per cent by weight of magnesium calculated as magnesium oxide (see Group III) at 200-550 DEG  C.  Diisobutene is particularly suitable as starting material. Liquid or vapour phase conditions may be used, increased pressure may be necessary in the former and decreased pressure, e.g. 0.01-0.5 atmosphere, can be used in the latter.  A catalyst grain size of 0.05-0.6 mm. is preferred and fixed or moving catalysts can be used. Throughputs of up to 1 litre of oligomer per Kg. of catalyst per hour in the fixed state or 10 litres with a moving catalyst can be used. Inert gases in an amount of 10-90 volume per cent may be used as diluents such as nitrogen, carbon dioxide, methane, ethane or propane. Regeneration of the catalyst is effected by burning off impurities with air.  In examples catalysts containing varying amounts of magnesium are used to depolymerize diisobutene at 400 DEG C., 10.7 g. of diisobutene, 2 litres (measured at standard conditions) being led per minute through 150 ccs. of catalyst.  No butene-1 is formed.ALSO:A synthetic magnesium silicate catalyst containing 1-20 per cent by weight of magnesium calculated as magnesium oxide is used to crack oligomers of isobutene to isobutene at 200-500 DEG  C. (see Group IV (b)).  The catalyst may be prepared by thermal treatment of silica and magnesium compounds such as the oxide, hydroxide, carbonate or oxalate or by coprecipitation, but preferably by impregnating silica with magnesium nitrate and heating to 500-900 DEG  C.  The silica to be impregnated is preferably in the form of shaped silica strings obtained by extruding a paste of silica with a solvent, cutting into 0.5-1 cm. lengths and drying. The catalyst can be used as a fixed bed or moving, and preferably has a grain size of 0.05-0.6 mm.  Regeneration when necessary can be accomplished by burning off resinous impurities with air.  In an example, 4 kg. of silica are treated with a solution of 2.83 kg. of Mg(NO3)26H2O in 38 litres of water, the liquid separated and the solid dried at 100 DEG  C. and heated for 2 hours at 700 DEG  C.  The catalyst so formed had a weight ratio of silica to magnesium oxide of 9:1.
