Title: Improvements in epoxidation
IPC: C07D303/48
Filed: 1958-11-12
Abstract: A 2,3-epoxy-alkanoate of an ethylenically unsaturated alcohol is produced by reacting an alkyl 2,3-epoxy-alkanoate of general formula: <FORM:0863445/IV (b)/1> wherein the valences of the epoxy carbon atoms are satisfied by a hydrogen atom or a hydrocarbon group and R1 is an alkyl group, with an alkenyl, cycloalkenyl or cycloalkenyl alkyl alcohol which contains an ethylenic group at least one carbon removed from the hydroxyl group in the presence of an alkali metal alcoholate or alkaline earth metal alcoholate for a period of time sufficient to produce the aforesaid 2,3-epoxy-alkanoate. Cycloalkenyl and cycloalkenylalkyl 2,3-epoxyalkanoates are novel compounds.  The reaction may be effected at temperatures in the range from 0 DEG  to 100 DEG C. under reduced pressures.  An inert diluent such as an aliphatic or aromatic hydrocarbon or an ether may be employed. Molar ratios of olefinic alcohol to glycidic ester of from 1,5:1,0 to 10.0:1,0 are preferred.  The product may be recovered by distillation after neutralisation of the catalyst, or alternatively the product may be recovered as a residue after distillation of excess alcohol.  The epoxy products may be copolymerized with vinyl chloride, acrylonitrile and like monomers (see Group IV(a)).  An example also describes the preparation of methyl 2,3-epoxy-butyrate by contacting methyl crotonate with peracetic acid.  Specification 863,446 is referred to.

The brassiere portion of the garment is formed of inelastic material. The garment may be worn beneath a bathing suit, as a dance belt, or may assume the form of a type of breeches or drawers having an upper body-confining portion.
Patent GB-997898-A (GB)
Title: Production of magnetic tape
Inventor: DEIBOLD ADOLF
IPC: G11B5/858
Filed: 1963-09-18
Abstract: Magnetic tape consists of a plastic tape substrate first rendered conductive by applying a conductive layer to the substrate by normal methods, and second electroplating a magnetic material thereon, preferably Ni/Co alloy, e.g. from an electrolyte of their complex compounds, e.g. tartrate, or nitrilo-acetate, and applied at low power, e.g. 0.01-20.0 A.S.D. The conductive layer may be nickel, graphite, bronze, copper, silver or aluminium in powder form, and applied by vapour deposition, suspended in a binder or emulsion, or blown on to the tape coated with adhesives. Binders specified include polyvinyl compounds, poly-acrylates, or other esters.  The Ni/Co deposition is improved by adding salts of alkalis or alkaline earth metals, and the magnetic properties are improved by including small amounts of metals of Group Va, VI, or VII.  An apparatus is shown in which the tape bearing a conductive layer is cleaned and etched before plating in a bath with the usual rollers.  In examples, the plating baths are (1) nickel and cobalt citrates and lithium chloride, (2) nickel citrate and chloride, and cobalt sulphamate, (3) cobalt tetra-acetate, cobalt chloride, nickel citrate, manganous sulphate, and ethylene diamine. Power applied is 2-4 volts at 0.5-1.0 A.S.D.  A magnetic field may be applied during electro-deposition.

Title: Improvements in or relating to apparatus for controlling the rotational speed of an aviation gas turbine engine
Inventor: WINTERS DONALD F
Filed: 1959-10-29
Abstract: 874,571. Gas turbine plant. WESTING- HOUSE ELECTRIC CORPORATION. Oct. 29, 1959, No. 36722/59. Class 110 (3). The rotational speed of a gas turbine engine is controlled by an engine-driven governor having speeder spring means and means controlled by the speeder spring means to maintain the rotational speed of the engine at a predetermined value, a temperature-sensitive element responsive to engine inlet temperature and movable in one direction in response to a rise in temperature and vice versa, a rocker associated with the temperature sensitive element and the speeder spring means to decrease the bias effect of the speeder spring in response to a decrease in inlet temperature and a stop member arranged to limit the travel of the temperature sensitive element upon a predetermined increase of temperature to render ineffective the modifying of the bias effect at an engine inlet temperature above a selected value. The fuel control apparatus 10 comprises mechanism 11 for sensing the actual rotational speed of the engine having pivoted flyweights 13 movable against the action of a spring 19 to move a spindle 17 axially. The spindle 17 is attached to a fuel valve servo mechanism to decrease the rate of fuel flow upon movement of the spindle to the right. The loading of the spring 19 against the flyweights may be varied by a lever 21 acting through a spool 20. A temperature sensing mechanism 24 operates through a lever 36 to vary the loading of a second spring 40 on the spindle 17. The mechanism 24 comprises liquid-filled bellows 25 disposed within a housing 26 through which flows air from the compressor inlet supplied by a tube 27. The bellows are supported at one end by a spring- loaded plate 29 and carry a rod 32 which actuates the rocker arm 36. The arrangement is such that at inlet air temperatures below a predetermined value, the rocker arm 36 reduces the loading of the spring 40 and so reduces the controlled actual speed of the turbine. As this temperature increases the bellows 25 expand and increase the loading of the spring 40 and so increase the controlled actual speed. This continues until the rocker arm 36 abuts against the adjustable stop 44. With a further rise in temperature the controlled speed is that set by the lever 21 and the expansion of the bellows 25 is taken up by the spring-loaded plate 29. In a modification, the rocker arm 36 acts directly on the spring 19.

Title: Bicycle hub having a built-in three ratio gear mechanism
IPC: B62M11/14
Filed: 1968-08-01
Abstract: 1,219,025. Change speed gear. SHIMANO KOGYO K.K. 1 Aug., 1968 [4 Aug., 1967], No. 36722/68. Heading F2D. In a three ratio cycle hub planet gear wherein a manual control 54 selects low, intermediate and high ratio ranges, automatic ratio shifts controlled by a centrifugal governor 33 are permitted between the lowest two ratios in the intermediate range and between the highest two ratios in the high range. The gear has planet pinions 17 on a carrier 20 meshing a fixed sun gear 16 and a ring gear 12 on a carrier 15. The planet carrier 20 and ring gear carrier 15 are selectively connected to a block 8 fast with a driving sprocket 11 by ratchet clutches 25, 22 and to a driven hub 2 by ratchet clutches 31, 28. The ratchet clutch 25 is held disengaged by a centrifugal governor 33 when the input speed is below a predetermined value. When the manual control 54 is moved left against the bias of a spring 51 it acts through pins 48, 50 and sleeves 47, 49 to disengage the ratchet clutches 25, 28. Operation.-With the control 54 moved left both ratchet clutches 25, 28 are disengaged and the block 8 drives the hub 2 through the ratchet clutch 22, ring gear carrier 15, planet gear 12,17, planet carrier 20 and ratchet clutch 31 for low ratio. On initial rightward movement of the control 54, the sleeve 47 releases a ball 56 which moves radially inward to release the tail 35 of the pawl 25 for intermediate range. Thereafter the ratchet clutch is held disengaged by the weights 33a, 33b of the governor 33. When the speed of the block 8 exceeds a predetermined value, the governor weights 33a, 33b pivot outwardly against the bias of a spring 43 to release the pawl of the ratchet clutch 25, whereupon the gear up-shifts to direct-drive with the block 8 driving the nub 2 through the ratchet clutch 25, planet carrier 20 and ratchet clutch 31. Further rightward movement of the control 54 engages the ratchet clutch 28 for high range. If the speed of the block 8 is low and the clutch 25 disengaged, the block 8 drives the hub 2 through the ratchet clutch 22, ring gear carrier 15 and ratchet clutch 28 for direct drive. When the speed of the block 8 exceeds a predetermined value to engage the ratchet clutch 25 the gear upshifts to overdrive ratio with the block 8 driving the hub 2 through the ratchet clutch 25, planet carrier 20, planet gear 17, 12, ring gear carrier 15 and ratchet clutch 28. When the input speed falls below the predetermined speed downshift is prevented until a torque reversal occurs to bring the pawl of the clutch 25 into a position in which it is held disengaged by the governor weights 33a, 33b. In Figs. 7-10 (not shown), the ratchet clutch between the ring gear carrier 15 and driven hub 2 is controlled by a centrifugal governor responsive to the speed of hub 2 whilst the ratchet clutch between the block 8 and planet carrier 20 is only controlled by the manual control 54. The operation is similar to that described above.

Abstract: 909,829. Sliding clasp fasteners. PLATE, K., and WAHL, N. A., [trading as PATENTGESELLSCHAFT PLATE & CO.]. Nov. 14, 1958 [Nov. 25, 1957], No. 36732/58. Class 44. A method of constructing a coil type sliding clasp fastener, the rows of coils 11 constituting the elements of which are each fixed to stronger tapes 10 by means of a backing member 17 and in which each coil is fixed to its backing member by strand material 18 the backing member being formed from individual threads consisting of textile fibres and/or thermoplastic material, comprises the step of attaching a long length of backing member material to a long length of coil material by the strand material, the step of interlocking two such sets of coil material, backing material and strand material to form an assembly and the step of connecting together the backing material and strand material of each set over the entire length thereof or at spaced intervals corresponding approximately to the desired row lengths, by impregnation by means of adhesives, starch or thermoplastic material if the threads consist of textile fibres, or, by melting if the threads include thermoplastic material, to prevent unravelling of the threads of the backing material. The assembly is cut into sections of the desired lengths in a known manner and the sections are sewn or welded to long lengths of stringer-tape forming material with spacings between. The backing member material is attached to its coil material by winding the strand material between the loops of the coil material and around the backing member material in a conventional winding machine. When the backing material and strand material of each set are connected by adhesive they are passed through a bath containing the adhesive, starch or a thermoplastic material. The adhesive, starch or thermoplastic material can if desired be washed out by means of suitable solvents after the sections are connected to stringer tape material. When the sets of material are connected by melting threads of thermoplastic material, the sets are passed through a machine having a heated reciprocating iron element which engage the sets at spaced intervals to melt the thermoplastic material. When desired an additional cord can be secured to the backing material to protect the backing material from wear and to prevent wobbling of the slider.
