Abstract: 926,103. Engine turning gear. SIMMS MOTOR UNITS Ltd., L. DANILEWICZ, and L. S. DANILEWICZ. Dec. 22, 1960 [Dec. 31, 1959], No. 44398/59. Class 7(5) Apparatus for use in starting internalcombustion engines comprises a shaft 11 means for driving the shaft, a pinion 13 in helical engagement with the shaft and slidable on the shaft with rotation relative thereto into and out of engagement with a gear 18 to couple the shaft to drive the engine, means restraining the pinion from rotating so that initial rotation of the shaft causes the pinion to move towards and into engagement with the gear stop means for preventing rotation of the shaft while the driving means is energised and until it is required to drive the shaft and means for rendering the stop means inoperative thereby to permit the driving means to drive the engine through the shaft pinion and gear in order to start the engine the pinion being caused by its helical engagement with the shaft to return out of engagement with the gear when the gear rotates at a faster rate than the shaft. The apparatus is a modification of that described in Specifications 853,817, 853,818 and 853,819 referred to. The output shaft 11 of the starter is coupled through a differential gear to a driving spring and to a handle for rotation to energise the spring through the differential gear and a nut engaging with a screw provided on the shaft 11. The spring 17 acts to bias the pinion, shank and ratchet unit 13, 14, 16 to the position shown in the drawing when the stop means are rendered inoperative to permit the driving spring to drive the shaft the restraining means are simultaneously rendered inoperative. The restraining means and the stop means comprise respectively two pawls 21, 22 which are alternatively engageable with a ratchet wheel 16 movable with the pinion, the two pawls being coupled together for simultaneous movement to their inoperative position. The energising spring may be interposed between its winding mechanism and the output shaft instead of being interconnected with them by means of differential gearing.

Patent GB-1056399-A (GB)
Title: Polymer foams and their properties
IPC: B32B5/18
Filed: 1965-10-26
Abstract: The invention comprises foamed poly(2,6-dimethylphenylene-1,4)ether, which may be made by incorporating a blowing agent in the resin and heating the resulting mixture to a temperature at which the blowing agent becomes active.  The preferred blowing agents are volatile liquids, used in conjunction with a nucleating agent, which may be a small amount of a blowing agent which decomposes on heating or a finely divided inorganic substance, e.g. vermiculite. Alternatively a blowing agent which decomposes on heating, e.g. azodicarbonamide may be used alone, or a gas under pressure may be used as the blowing agent with a finely divided metal as the nucleating agent.  The poly(2,6-dimethylphenylene-1,4)ether used preferably has a relative viscosity of at least 1-30 measured on a 1g. solution of the polymer in 100 ml. of benzene.  The expansion is suitably performed between two plates which are fixed during heating of the polymer, but which subsequently move apart parallel to one another to allow expansion in one direction.  The foam thus formed has elongated cells, usually with a length at least five times their largest width, and has an increased compressive strength in the direction of elongation. Expansion between sheets of plywood, aluminium or melamine-formaldehyde resin to form laminates is also described.

Filed: 1964-11-09
Abstract: The invention comprises anthraquinone dyes of the formula <FORM:1078103/C4-C5/1> wherein X is H or an alkali metal.  The dyes may be obtained by the reaction of a dye of the formula <FORM:1078103/C4-C5/2> with an alkali metal salt of thiosulphuric acid in an aqueous medium at pH 3-8.5.  The pH value may be adjusted to the desired value by addition of an acid (organic or inorganic) throughout the duration of the reaction, by using a buffered solution of a weak acid or by introducing the thiosulphate and the acid simultaneously. The reaction may be carried out at 10-100 DEG  C. The dyes may be employed to dye cellulosic, wool, silk or polyamide fibres. Examples are given.

Filed: 1972-10-05
Abstract: 1400754 Turbines; gas turbine plant; axial and centrifugal compressors LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT 5 Oct 1972 46019/72 Headings F1C F1G and FIT A rotor for a gas turbine engine includes an annular drum 23 having radially inwardly projecting ceramic turbine blades 22. In the arrangement shown in Fig. 2 the rotor drum 23 is of aluminium alloy or of boron or carbon fibres and also carries radially outwardly projecting axial-flow compressor blades 48. The latter deliver air via volute housing 55 to centrifugal compressor blades 54, 53 carried by a disc 24 forming the end-wall of drum 23. The compressed air discharges through a diffuser 56, ducts 58 and pipe 59 into a combustion chamber. Combustion gases from the latter enter a volute housing 16 and are directed by guide vanes 29 to rotate turbine blades 22 before being deflected by vanes 30 into an outlet channel 32 for use in jet propulsion, furnaces or boilers, or to rotate the blades (61), Fig. 7 (not shown) of a separate power turbine. Turbine blades 22 are of alumina and are mounted on the inner surface of drum 23 via metal insert 25, Fig. 3, having ribs 25 engaging channels 38 in the drum. Insert 25 has axially spaced legs 25b to which the blade roots are secured by pins passing through bores 25c in the legs. Ceramic inserts 26 are disposed between adjacent blade roots, the latter having tabs 22a engaging grooves 26b in the inserts to prevent rotation. The inner ends of blades 22 are supported in grooves 28a of a ring 28. Cooling of rotor drum 23 is effected by water supplied through an axial duct 34 in shaft 10 and directed through radial ducts 35 in disc 24 to an annular channel 36 in drum 23. The water thence flows through passages 37, 38, 39, (40, 41), Fig. 5 (not shown) before being collected in a fixed channel 42 discharging to a cooler. Additional air coolant is also directed through fixed axial ducts 47 and the radial space 45 between a heat shield 44 and disc 24 to space 45, before discharging into the gas stream. Steam coolant may also be used. Space 45 may alternatively be filled with a heat insulating material. Such material 17 also surrounds volute housing 16. The rotor may be supported on air bearings. The power turbine Figs. 1, 7 (not shown) is constructed in similar manner to the compressor driving turbine described, with the exception that the cooling water undergoes alternate forward and reverse passes through the rotor drum (62). The gases (80, 81, 82) exhausting from power turbine blades (61) pass through a regenerator.

The holding means are pivotally adjustable about an axis 28 on the frame 1 in order that the distance between the holding means and the cutter may be varied so that, in operation, the tension of an endless flexible driving means coupling the first driving member to a second driving member fitted to the drive shaft of the power hand tool held in the holding means may be adjusted. As described an electric or pneumatic drill 26 is held in the holding means 27 and its position is determined by a bolt 30 threaded in a bar 32. The drive shaft of the drill carries a pulley or sprocket 33 which via a belt or chain 34 drives a pulley or sprocket on the shaft 10 of the cutter 6. A shield 36 for the belt or chain is provided. The cutter 6, Fig. 3, includes a pair of adjustable blades 7 and the bearings 11 for its shaft 10 are carried by a rigid plate 13 and a spring plate 12. The depth of cut produced by the cutter is adjusted coarsely by adjusting the position of the plate 12 along studs 15 on the base 2 using nuts 16, 17, and is adjusted finely by a knob 18 and a rod 19 threadedly engaged with a nut secured to the plate 13. In a second embodiment, Fig. 4, cutter blades 45 of the cutter are adjustably mounted in cylindrical blocks 40 received in corresponding recesses in the cutter body so that the angle of the blades as well as their amount of projection from the cutter body can be varied.
