Title: Improvements in aircraft
IPC: B64C13/00
Filed: 1937-03-03
Abstract: 497,077. Aeroplanes. SPRATT, G. G. March 3, 1937, No. 6309. Void. Convention date, March 4, 1936. [Class 4] An aeroplane wing is tiltable about a lateral and a longitudinal axis to effect control of the craft. In one form, a two-spar wing 25, Fig. 1, is mounted on a pylon 26 by a universal joint 29 and is braced by wires 27R, 27L and 28R, 28L to the extremities of an H-shaped frame carried beneath pivot 33 of a control column 31. Rotation of wing 25 about the normal axis is controlled by wires 30. Fore and aft movement of column 31 causes the wing to rock about a transverse axis whilst lateral movement causes tilting of the wing about a fore-and-aft axis accompanied by slight rotation about the normal axis due to the forward slope of wires 30. A pusher airscrew 24 is mounted in an annular housing 23 serving as a pin. A pair of rear wheels 2 and a single forward wheel 22 are provided and the latter may be steered by connection to the lateral control transmission. In a modification in which a single spar wing is rocked about axis X-X<1>, Fig. 4, by chain and cable gear; rotation about axis Y-Y being effected by a lever and link system. Further modifications are described in which a restoring tendency is given to the wing, in one such arrangement struts 68R, 68L, Fig. 7, are pivoted to rollercarrying members guided on a straight transverse member 73, interconnecting longer arms 70L 70R. In another arrangement left- and right-hand struts meet at a point at which a roller is mounted movable in a transverse camslot, and in a still further arrangement the lateral struts are pivoted to the mutually connected ends of inwardly-angled levers rockable about fore-and-aft axes by rack and pinion mechanism. The arrangement shown in Fig. 4 may be modified by arranging the chain interconnecting bracing wires on a single central sprocket rotated through a cardan shaft and chain gear from the hand-control wheel. The aircraft is stated to be applicable for road use in which case the wing is rotated about the normal axis into a position in line with the body. The control system may be applied to a tailless aeroplane or to conventional tractor aeroplanes.

Patent GB-1065336-A (GB)
Title: Sulphoxides and their use as pesticides
Inventor: AICHENEGG PAUL CONRAD
IPC: C07C317/00
Filed: 1966-02-15
Abstract: The invention comprises compounds of the formula (CHX2CHX)SO, where the X's are the same or different and represent chlorine or bromine. The compounds can be prepared by oxidizing the corresponding sulphides with peroxides, e.g. by oxidizing pure bis(1,2,2-trihaloethyl)sulphide with hydrogen peroxide or peracetic acid or by oxidizing the crude sulphidedisulphide mixture and separating the sulphoxide from sulphuric and sulphonic acid by-products. Examples relate to the preparation of bis(1,2,2-trichloroethyl) sulphoxide (in a crystalline and an oily form).  The compounds are used as pesticides (see Division A5).  The sulphide starting materials may be made by (1) reacting sulphur dichloride with 1,2-dichloroethylene, or (2) reacting 1,2,2-trichloroethyl sulphenyl chloride with 1,2-dichloroethylene in the presence of AlCl3 or FeCl3.  In method (1) some corresponding disulphide is obtained as a by-product.  Examples 1-3 describe the preparation of such sulphides. Example 5 relates to the separation of the required sulphide from a mixture of a sulphide and disulphide by conversion of the disulphide to the corresponding sulphenyl chloride by treatment with chlorine.  Pure sulphides can be prepared by converting the crude sulphide to the sulphoxide of the invention, isolating the sulphoxide and reducing the pure suphoxide to the sulphide, e.g., using TiCl3 in HCl (Example 4).  Example 9 relates to the preparation of bis (2,2,2-trichloroethyl) sulphoxide, made for comparative purposes, by oxidizing the corresponding sulphide which in turn is made by reacting vinylidene chloride with sulphur dioxide (Example 8).ALSO:Pesticidal compositions comprise a sulphoxide of the formula (CHX2CHX)2SO in which X substituents are the same or different and represent chlorine or bromine and a liquid or solid diluent.  The compositions have particular use as nematocides and fungicides.  The liquid diluent may be water or an organic liquid. The compositions preferable include surfactants, many of which are specified.  Examples describe the use of the novel compositions containing bis(1,2,2-trichloroethyl) sulphoxide in combatting nematrodes and fungi and include comparative data relating to the activity of bis(2-chloroethyl) sulphoxide, bis(2-chloroethyl)sulphone, bis(2,2,2-trichloroethyl)sulphoxide and bis(1,2,2,2-tetra-chloroethyl)sulphoxide.

Filed: 1942-05-28
Abstract: 578,744. Fluid-pressure servomotors. LUCAS, Ltd., J., WATSON, E. A., and IFIELD, R. J. May 28, 1942, No. 7243. [Class 135] [Also in Group XXVIII] Means for automatically controlling the supply of liquid fuel from a pump to a prime mover driving the pump, comprises a main governor which is operated by fluid pressure responsive to speed, and a supplementary governor which is responsive to a rate, of change of speed. In the form shown in Fig. 1, a swash-plate pump a has an-inlet i and an outlet k, the latter being connected by a passage l to a cylinder p containing a apring-loaded piston q connected by a rod s to the swash-plate e. The two ends of the cylinder p are connected by a restricted passage t, and its outer end is provided with a small vent u with a closure member v carried by a spring-pressed leverw in a chamber y connected with. the inlet i. The lever w is engaged by an abutment 2 on a spring-loaded diaphragm z connected to an adjusting member 6. The rotary body part of the swash-plate pump a is formed with radial passages o connected to the inlet i by ports m, n, the liquid expelled by centrifugal action being led by a passage 4 to a chamber 3 beyond the diaphragm z. An increase of speed therefore reduces the stroke of the swash-plate' pump a. Beyond the chamber 3 is a further chamber divided by a second diaphragm 8 and'bellows 13 into two compartments 9, 10 interconnected by a restricted passage 14, the outer. compartment 10 having an inlet 15 for connection to an air blower, or any other source of fluid pressure, which varies with change of speed of the prime mover. A rapid increase in speed, therefore, again reduces the stroke of the pump a. In the form shown in Fig. 2, the passage 4 has a restriction 20 and the chamber 3 communicates with the larger end of a stepped cylinder 16 which contains a spring-pressed piston 17 and is connected by a pipe 19 to the pump outlet k. In modifications, the additional pressure in the chamber 3 is obtained by means of a spring- pressed piston which forms the movable core of an electromagnet, the energizing winding of which is supplied with current from a generator whose output is responsive to the speed of the prime mover, or which is subject to the action of a centrifugal mechanism responsive to the speed of the prime mover.

Abstract: 1,205,061. Extruding press. MASCHINENFABRIK SACK G.m.b.H. 14 Feb., 1968 [17 Feb., 1967], No. 7314/68. Heading B3P. An extrusion press comprises a press cylinder 2 connected to a die support beam 3 by at least two segments 14, each of which extends between the cylinder and the beam and subtends an angle of less than 180 degrees at the cylinder axis. Two segments are preferably used and each subtends an angle of 90 degrees. The segments have an arcuate cross-section although polygonal cross-section segments could be used. The press piston 5 has a plunger 7 to eject a billet 10 from a support block 11 into a container 8. The container is mounted in a holder 23 which can be retracted after the extrusion by rams 9 in slots 44 in the segments so that the shear 12 can sever the billet. The cylinder 2 and the beam 3 each have an annular flange 16 which is engaged by a groove 15 on each segment 14. The segments are clamped to the cylinder and the beam by anchors 17, 19 and the anchors 17 around the cylinder provide supports for cylinders 22 which move the plunger carrier 6 adjacent the billet before the extruding pressure is applied. The carriage 6 and the holder 8 each have guide shoes (24), (26), Figs. 4 and 5 (not shown), which slide along the edges of the segments. Spacing blocks 45, 46 limit the bending of the segments. In a modification the cylinder has a removable base (28), Fig. 7 (not shown), which is bolted to the cylindrical wall (27) and the bolts (29) have plates (32) to clamp the flange 16 and groove 15 together. The base (28) may have extensions (34), Fig. 8 (not shown), which support the cylinders 22 instead of the anchors. In a further embodiment, the flanges and grooves are shaped so that the clamping force causes the segments to be urged inwards and eliminates the need for the anchors, Figs. 9 and 10 (not shown). In a further modification the segments are each extended circumferentially in the region of the groove, Figs. 16 and 19 (not shown), in order to make the centre of area of the segment cross-section coincide with the resultant of the applied force to eliminate bending moments. Each segment is shaped along the whole of its length so that the centre of area for any crosssection coincides with the resultant of the applied force.
