Title: Lubricating compositions
IPC: C10M101/02
Filed: 1956-02-23
Abstract: A lubricating composition, suitable for use at high temperatures in gas turbine engines, comprises a major proportion of an aromatic-free essentially isoparaffinic lubricating oil and a minor proportion of an oil-soluble zinc, cadmium or lead salt of a thiocarbamic acid. The lubricating oil may be prepared by the isomerization of hydrocarbon wax (see Group IV (b)) followed by dearomatization.  The thiocarbamic acid may have the formula: <FORM:0783158/III/1> wherein R1 is a hydrocarbon radicle, R2 is hydrogen or a hydrocarbon radicle and X1 and X2 are oxygen or sulphur, at least one of them being sulphur.  The lubricating composition may also contain a minor proportion of an amine which may be aliphatic, aromatic or heterocyclic.  Suitable amines are phenyl-a - or b -naphthylamine, N,N,N1,N1-tetramethyl diaminodiphenyl methane, dicyclohexylamine, N-phenyl morpholine, octadecylamine and amines derived from paraffin wax or from coconut oil acids.  In examples, lubricating compositions are described consisting of a lubricating oil, obtained by isomerizing paraffin wax and refining the product, together with zinc, cadmium or lead diamyl dithiocarbamate, zinc dibutyl dithiocarbamate or a blend of zinc and cadmium diamyl dithiocarbamate.  For comparison purposes, lubricating compositions are described containing (1) the same lubricating oil and one of phenyl a -naphthylamine, neutral or basic calcium petroleum sulphonate, basic calcium C14-C18 alkyl salicylate, zinc C14-C18 alkyl salicylate, zinc or cadmium petroleum sulphonate, tin diamyl dithiocarbamate, copper di-2-ethyl-hexyl dithiocarbamate and nickel dibutyl dithiocarbamate; or (2) mineral lubricating oil or di-2-ethyl-hexyl sebacate and cadmium diamyl dithiocarbamate.ALSO:An essentially isoparaffinic lubricating oil, employed as an ingredient in lubricating compositions (see Group III), is prepared by the isomerization of paraffin wax.  The paraffin wax can be isomerized in the vapour, liquid or trickle phase in the presence of a catalyst, such as platinum, palladium, nickel, cobalt, molybdenum or an oxide or sulphide thereof.  The molybdenum may be in part or completely substituted by chromium, tungsten, uranium, manganese or vanadium, while the catalyst may be applied on a carrier such as alumina or activated bauxite.  The isomerization should be carried out at a temperature of at least 300 DEG  C. and in the presence of a large proportion of hydrogen. Reduced or elevated pressures, or atmospheric pressure, may be employed.  The isomerization may be followed by a de-aromatization and/or fractionation, if necessary.  In the examples, paraffin wax is isomerized in the vapour or liquid phase, in the presence of hydrogen and of a platinumalumina catalyst.

Abstract: 1,088,143. Moulding spark plug insulators. A. RUPRECHT and D. VON DER OSTEN. Feb. 11, 1965 [Feb. 13, 1964], No. 5887/65. Heading B5A. In an automatic process for making a sparkplug insulator, ceramic composition is introduced from a filling shoe into the stepped bore 14 of a sleeve 6 flush with a table 7 closed at its lower end by a stationary bottom ram 15 supporting a pressing needle 16. The shoe then moves to the right and an upper ram 5 having a cavity 19 corresponding to the shape of the end of the insulator, descends into the sleeve until its lower edge is at a distance equal to the length of the collar 2 of the insulator away from the shoulder 18 in the sleeve bore after which the sleeve and ram descend together down the stationary ram 15 to compress the ceramic material. When pressing is complete, the upper ram 5 moves back up and the insulator is gripped by a bifurcated holder 9. The sleeve and table 7 which supports the holder move up whereby the pressed insulator is drawn off the pressing needle. The filling shoe is then moved into filling position causing the holder connected thereto to move over the edge of the table to drop the insulator 11 on to a conveyer.

Title: A process of coating a strand of glass fibres with a resinous material
IPC: D06B15/08
Filed: 1955-03-03
Abstract: 774,031. Coating threads. OWENS-CORNING FIBERGLAS CORPORATION. March 3, 1955 [March 11, 1954], No. 6350/55. Class 140. [Also in Group IX] A process of coating a fibrous strand with resinous material comprises putting a strand composed of a plurality of closely adjacent glass fibres longitudinally through a mass of liquid resinous material and feeding the threads having excess material into and through a fixed die having an aperture of size which diminishes in the direction of movement of the fibres so as to remove excess material and exert a compressive force before the excess material is removed, whereby the material is forced at least partly between at least some of the fibres in the strand. The threads 22 are unwound from spools 20 on a creel and pass through guides 23, 24 before passing through wipers 41 having dies 42. The threads then pass to a fusing oven 27 and then over rollers 69 and between rollers 32 to separate winding spools 29 having a constant speed wind. The resin is pumped by motor 46 to a manifold 44 having a slot 45 extending forwardly and beneath the wiper 41. The wiper has an oblong blade 47 pivoted on a transverse shaft 50 the thread and resin pass through a slot in the blade and then the thread passes through a die 42. The die comprises a cup 56 with a centre 57 having an opening where the resin is compressed on the threads and an outlet which limits the thickness of coating the excess spilling on to a screen 38 through which it passes to a container 35 having an outlet which leads the resin through a filter 54 if necessary to the pump. Should a filament break while passing through the oven, the thread is secured to one of a series of slats 68 secured to an endless belt 67 traversing the oven. In an alternative coating apparatus shown in Fig. 12, a roller 79 rotates partly in the resin and feeds the resin to an inclined plate 80 leading to a wiper 85 and die 86. The thread passes over a guard 82 to the wiper and die. In a further embodiment the resin is fed from a hopper to a horizontal cylinder through which the thread passes, the inlet and outlet of the cylinder comprise converging members.

Title: Improvements in or relating to electro-mechanical wave filters
IPC: H03H9/48
Filed: 1936-03-03
Abstract: 453,748. Acoustic wave filters. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Blackman, R. B.) March 3, 1936, No. 6415. Convention date, April 20, 1935. [Class 13] [See also Groups XXXIX and XL] A wave filter comprises a longitudinal stretched wire and a plurality of transverse stretched wires coupled mechanically to the longitudinal wire at their middle points and spaced along its length. Two of the transverse wires are located in gaps of a magnet system arranged to produce fields perpendicular to the wires. Mechanical vibrations produced by oscillatory current supplied to one of the wires are applied to the filter arrangement to effect vibrations of the other transverse wire which are utilized to produce current variations in a circuit including the second wire. In the arrangement shown in Fig. 1, the longitudinal wire 16 is connected to the pole plates 12, 121 of a magnet 11 and contacts with wires 15, 15<1> mounted in gaps between the plates 12, 12<1> and a centre polepiece 13. A transverse wire 18 contacts with the wire 15 which is also loaded by inclined wires 17, 17<1> mounted in slots on the polepieces. Fig. 3 shows in detail the arrangement for supporting and tensioning the wires. The transverse wires 15, 15<1> are stretched across bridge-pieces on a plate 14 and one end of each wire is secured to an adjustable tensioning lever 35. The wire 16 and the transverse wires 17, 171, 18 are carried by a cover plate 19 mounted on the pole plates 12, 12<1> by brackets 21, 211 and pins 22, and are supported by bracket members, such as 31. As shown in Fig. 5, the wire 17 has one end attached to a bridge 32 and the other end secured to an adjustable tensioning lever 32<1>. Vertical adjustment of the bracket 31 is effected by a screw 29 passing through the cover plate 19. If all the wires are of the same material and subjected to the same tension, the wires 17, 17<1> and 18 are arranged to be of the same length, the wires 15, 15<1> being twice as long and the longitudinal wire 16 three times as long. The lengths and tensions of the wires 17, 171, 18 should be such that their fundamental resonance frequency is at the middle frequency of the transmission band of the filter and is twice the frequency of the tuned driving wires 15, 15<1>. The theory of the operation of the arrangement is discussed mathematically in the Specification, and the electrical equivalents of the elements of the filter are indicated in connection with Figs. 7 to 11 (not shown).
