Title: Improvements in or relating to synthetic lubricating oils
IPC: C07F9/08
Filed: 1949-09-13
Abstract: Compositions suitable for use as lubricants or additions to lubricants are prepared by reacting one molecular proportion of phosphorus oxychloride with three molecular proportions of a branched chain alcohol having from 8 to 20 carbon atoms in the molecule or a mixture of such alcohols, obtained by the "oxo" process, i.e. by the process of reacting carbon monoxide and hydrogen in the presence of a catalyst and an olefin or a mixture of olefins containing from 7 to 19 carbon atoms per molecule and hydrogenating the resulting aldehyde.  When mixtures of olefins are used, they should not contain more than 20 per cent of olefins of formula R.CH = CH2, where R is a straight-chain alkyl radical.  Suitable olefins are those from polymerization of a C3 and C4 olefine mixture, diisobutylene from acid polymerization of isobutylene, or olefins obtained by treating with bauxite a Fischer synthesis product boiling above 350 DEG  F. Alcohols mentioned are 3,5,5-trimethyl-hexanol-1, 2-isopropyl-3,3-dimethyl-butanol-1, and 2,2,4,4-tetramethyl-pentanol-1.  In examples, one mol. of alcohol, 1.1 mols. of pyridine and 1/3 mol. phosphorus oxychloride are reacted in benzene solution.  Properties are shown of products obtained from C8, C9, C11-12, C12-13 and C13-14 "oxo" alcohols, derived respectively from a C7 olefin obtained by polymerizing C3 and C4 olefins, a commercial diisobutylene containing 80 per cent olefins of the formula <FORM:0664127/IV (b)/1> and 20 per cent of formula <FORM:0664127/IV (b)/2> where R, R1 and R11 are alkyl radicals, and from a Fischer synthesis product treated with bauxite at 850-950 DEG F.  The Specification as open to inspection under Sect. 91 relates to esters from C8-C20 branched chain alcohols generally. This subject-matter does not appear in the Specification as accepted.ALSO:Phosphate esters, suitable for use as lubricants or as additives for mineral lubricating oils, are obtained by reacting one molecular proportion of phosphorus oxychloride with three molecular proportions of a branched chain alcohol having from 8 to 20 carbon atoms in the molecule, or a mixture of such alcohols, obtained by the "oxo" process, i.e. by reacting carbon monoxide and hydrogen in the presence of a catalyst and an olefin or mixture of olefins containing from 7 to 19 carbon atoms per molecule and hydrogenating the resulting aldehyde.  Alcohols mentioned are 3, 5, 5, -trimethylhexanol-1, 2 2-isopropyl-3, 3-dimethylbutanol-1, and 2, 2, 4, 4-tetramethylpentanol-1.  With oils the esters are preferably blended in proportions from 1 per cent to 10 per cent by weight of the oil which may be obtained from petroleum or may be a synthetic product, e.g. obtained by polymerizing olefins or by the hydrogenation of coal. Thickeners, pour depressants, antioxidants or dyes may be added.  As open to inspection under Sect. 91 the Specification relates to esters from C8-C20 alcohols generally.

Patent GB-488681-A (GB)
Title: Toasting machine
IPC: A47J37/08
Filed: 1937-09-01
Abstract: 488,681. Toasting-apparatus. REBOIS, L. V. Sept. 1, 1937, No. 23911. [Class 28 (i)] In a machine for toasting slices of bread in contact with hot plates, the plates are assembled in annular formation and are rotated, step by step, in an annular casing having an opening at which the supply of slices to, and removal of toast from, the plates are effected. The lowei plates 11 extend outwardly from a flange 10 on a casing 9 secured to arms 6 on a hub 5 on the central shaft 4. The upper plates 12 are each carried by a vertically sliding rod 17 so that it is lifted at the opening in the casing, access to the lower plate 11 being facilitated by the tilting of the plate 12 by the abutment 61. The machine is driven by a motor connected by a belt to a worm shaft 23 which drives a worm-wheel shaft 28 carrying rollers 32, 34 on radial arms 31, 33 and a roller 35 projecting upwardly from the worm wheel. The roller 32 engages, once in each revolution, a toothed wheel 32a which is thus rotated intermittently to move the plates 11, 12 one step forward. The rollers 34, 35 are arranged, one above and one beneath a sliding plate 40 with cam surfaces thereon, such surfaces being so arranged that the rollers 34, 35 move the plate backwards and forwards, and hold the plate stationary between the movements. The plate is connected by a rod 55 to a bell-crank lever 52 one arm of which projects into a cross-head 58 connected by a web 57 to an upper U-sectioned cross-head 59, the whole cross-head assembly being guided for vertical movements. The rods 17 carrying the plates 12 each have a roller 16 which, at the opening in the casing, runs into the U-shaped cross-head 59 which is then raised, by the cam plate 40, to lift the plate 12 for discharge of the toast and re-charging. The cam plate 40 then lowers the plate 12 and the newly filled plates move into the casing. Pressure is applied momentarily to the bread by the roller 16 engaging a short-shaped cam section mounted on a vertically sliding rod continuously urged downwardly by a coil spring, the cam having a notch in which the roller 16 engages to prevent the momentum of the rotating assembly from carrying the next plates past the charging and discharging position. The toast is stripped from the plates 12 by pins 62 secured to plates 63 nesting, by gravity, on the plates 12. Heating elements 81, 81a are arranged above and below the plates 11, 12 and the casing is insulated against heat losses at 78, 79, 79a, 80, 82 the central insulation 79a being rotatable with the plate assembly. To prevent loss of heat at the charging and discharging opening in the casing, baffles are arranged radially between each set of plates. The plates may be ribbed for heat conductivity and rigidity and may be provided with embossed designs to mark the toast correspondingly.

Filed: 1951-10-15
Abstract: 715,628. Wrapping machines. JORG, P. Oct. 15, 1951, No. 23961/51. Class 94 (1) [Also in Group V] Slabs of butter and the like are ejected vertically from the mould of a moulding machine (see Group V) into the wrapping mechanism of Fig. 4. Before ejection of the slab a wrapper is placed on the reciprocating frame 44 which is slid automatically into the path of the ejected slab. The slab is urged into the wrapper and through the flaps 47, 43 which fold the wrapper over the top and four sides of the slab. The partially covered, slab is held in position by a pair of spring-mounted holding- plates 42 whilst the paper is folded over the lower side of the slab. This folding action is performed by two pairs 59, 59<SP>1</SP>; 60, 60<SP>1</SP> of slidable fibre plates which are connected by the pin- and-slot mechanisms 55, 57; 54, 56 to a circular plate 52 and are urged towards each other when the plate 52 is turned through an arc by the link 51. At the end of this arc two further pins 64 on the circular plate 52 engage slots 63 in extensions 62 of the holding plates 42 and momentarily release the plates. The circular plate 52 then returns to its former position and the wrapped slab is ejected from the wrapping mechanism by the next oncoming unwrapped slab. The moving parts of the wrapping mechanism are actuated bv cams and levers (not shown) associated with the moulding machine.

Abstract: 1524098 Magnetic locks ENGINEERING SYSTEMS CORP 11 June 1976 [20 Feb 1976] 24212/76 Heading E2A A magnetic lock comprises a lock body 30 in which are disposed a plurality of fixed magnets 36 and aligned holes 38 containing movable magnets 42. A rotor 31 is rotatably attached to the body 30 through lock shaft 32 and is provided with holes 61 into which magnets 42 extend by reason of the repulsive force of fixed magnets 36 and so prevent the rotation of the rotor 31. A key 12 is provided with magnets 36 which repel magnets 42, driving them back into holes 38 and freeing the rotor 31. A D-shaped depression is provided on the outer surface of the rotor and a similarly shaped protrusion 11 on the mating face of key 12. This enables rotation of the key 12 to turn rotor 31, when this is freed, and hence shaft 32 which, in turn operates a latch. A large number of different locks may be obtained by altering the number, disposition and polarity of magnets 42 in holes 38.

Title: Improvements in haulage clips
IPC: B61B12/12
Filed: 1930-08-13
Abstract: 358,647. Haulage clips. ROTHWELL, N., Masons Arms, Leeming Street, Mansfield, and SMITH, J. W., Boughton Road, New Ollerton, Newark, both in Nottinghamshire. Aug. 13, 1930, No. 24213. [Class 78 (ii).] In a clip of the kind d comprising fixed and movable oppositely disposed jaws and a pivoted lever having an extension freely engaging with a slot in the movable jaw, displacement of the lever in either direction imparts to the jaw successive movements in two directions at an angle to each other, one of said movements being laterally of the rope and the other longitudinally thereto. The movable jaw 4 is formed with a slot 11 which receives the nose 9a of the lever 8, and with recesses 12, 15 which when the jaw is in the open position fit over correspondingly shaped parts 13, 16 of the fixed jaw 1. Inclined faces 17, 18 on the jaw 4 co-operate with similar faces on the jaw 1 after the projections have left the recesses to produce the tightening of the clip on the rope by a wedge action. If a tub overtakes the clip, the hook 5 will become more inclined and a projection 5a on it will come into contact with the end face of the jaw 1 and produce a wedging action tending to force the jaw in a direction for maintaining the grip. A pin 19 on the jaw 4 projects into an angular slot 20 in the jaw 1. An interchangeable liner 21 is provided on the jaw 1. In a modification, Fig. 4, means are provided for preventing the release of the movable jaw without manipulation of the lever. This means comprises a wedge 22 which is pivoted to the lever and is jammed between a part 23a on the jaw 4 and a part 13b on the jaw 1 when the clip is gripping the rope.

Title: Severing glass sheets
IPC: C03B33/033
Filed: 1965-06-09
Abstract: A method of cutting a continuously moving ribbon of glass comprises supporting the ribboe on a fluid film (e.g. air) transversely scoring th moving ribbon supported on the fluid film and finally severing the ribbon along the score line to produce sheets of glass.  A continuous ribbon of glass is conveyed on to a table 13 the upper surface of which has holes 14 (Figs. 2, 3, not shown) for the passage of air under pressure thus forming a support film for the ribbon. The ribbon passes under a bridge 19 along which a scoring device 18 (Fig. 1, not shown) travels transversely across the ribbon face.  The scored ribbon then passes to a severing device 23 where it is snapped along the score line by breaker-rolls.  The sheets thus produced are then rapidly conveyed away.  A pulse generator 30 controls the timing of the scoring device and the snapping device 23, and also calculates the frequency of the scores to be made.
