IPC: C10M101/04
Abstract: 507,636. Lubricating compositions. ARNOLD, C. (Standard Oil Development Co.). Dec. 16, 1937, No. 34917. [Class 91] A lubricant for use by itself or as an addition to ordinary lubricating oils, consists of a thickened and hydrogenated organic ester or mixtures of esters. The thickening is effected by polymerizing by the influence of heat or voltolization. The hydrogenation is preferably carried out at 100-250 C. in the presence of an active hydrogenation catalyst, the final product having a viscosity of over 500 secs. at 210 F. The esters are those of polyhydric alcohols, or of polybasic acids, or synthetic esters of polyhydroxy compounds such as are obtained by esterifying glycerol or glycol with the acids obtained by the oxidation of wax, or with ricinoleic or stearic acid. The esters dibutyl phthalate, tricresyl phosphate or ethyl dibenzyl malonate are also included. In an example, linseed oil is thickened by heating for 10 hours to 575 F. in a glass vessel and the product is partly hydrogenated by treatment with hydrogen in the presence of an activated nickel catalyst at 2000 lb. per sq. in. pressure and at 212-225 F. To remove solid suspended matter, the thick oily product is dissolved in 5 volumes of ether, cooled to -40 F. and filtered. The product has a viscosity of 1175 sees. at 210 F. and an iodine number of 83.

Abstract: 1436436 Laminates DUNLOP Ltd 14 Oct 1974 [3 Nov 1973] 51144/73 Heading B5N [Also in Division A6] A laminate is formed of a wood layer sandwiched between two resin-impregnated fibre layers. Preferably, the resin impregnated fibre layer, which is of thickness 0À004 to 0À015 inch, contains by weight 40-60% fibres, and the wood layer which is of thickness 0À125 to 0À25 inch is formed of a low density (#0À45.10<SP>3</SP> kgm.<SP>-3</SP>) wood; e.g. obeche, balsa. In one embodiment, the resin-impregnated fibre layer is formed by the impregnation of a woven fibre sheet with a thermosetting resin, e.g. epoxy, phenolic, polyester or urea-formaldehyde. The fibres themselves are preferably of a low density (#1À6.10<SP>3</SP> kgm.<SP>-3</SP>) high elastic modulus (Young's Modulus #50 GNm.<SP>-2</SP>) type; e.g. aromatic polyamide. The resin impregnated fibre layers may be formed separately and cured before bonding to the wood with a suitable adhesive (e.g. epoxy resin) or may be formed by initially impregnating with resin and then curing and bonding to the wood in a single operation (the resin itself acting as a bonding agent). In the latter case the curing temperature should not exceed 100‹ C. to avoid wood damage; the range 80-100‹ C. being preferable.

Abstract: 1373408 Punching; stamping P C PEDDING- HAUS and W PEDDINGHAUS [trading as PAUL FERD PEDDINGHAUS] 5 Nov 1971 [5 Nov 1970 (2)] 51528/71 Headings B3W and B3Q A punching, or stamping machine has an operating lever one end of which is arranged to move a punching etc. tool through a working stroke when the other end is acted on by at least one eccentric in direct engagement therewith, the or each eccentric being mounted in the machine frame and rotated in a direction corresponding to the direction of pivoting of the lever at the start of the punching stroke, the arrangement being such that at the beginning of the working stroke the lever engages the cam at the point on the cam periphery closest to the axis of rotation of the cam, whereby during 180 degree rotation of the cam from the beginning of the working stroke, the movement exerted by the lever on the stamping or punching member increases and then decreases according to a substantially sinusoidal function. In a punching machine, Fig. 1, the operating lever comprises a pair of arms 11 and (10), Fig. 2 (not shown), pivoted to frame plates 4, 4a by a shaft 9 and connected at one end to a punch ram 5 by means of a shaft 12. The shaft 12 is connected via an eccentric 27 to a block 13 slidable in the ram 5. Rotation of eccentric 27 adjusts the vertical position of the ram. Elongated-holes in the plates 4, 4a allow for vertical reciprocation of the ram. The other end of the lever arms (10), 11 rest on coaxial eccentrics (16) 15 respectively mounted on a shaft (17), Fig. 2. The shaft (17) is rigid with a wheel 18 driven by a motor 22 via a belt 21, gear 20 and pinion 19. To cause a working stroke the eccentries are rotated in direction G, Fig. 6, moving from the initial position, in which each contacts its respective arm at P, to the broken-line position which pivots the arms (10), 11 about the shaft 9 in a direction corresponding to direction G. This movement of the pivot P, to point P1, increases the magnitude of the movement (S), Fig. 5 (not shown), to S<SP>1</SP> to give maximum punching force when the tool has passed through approximately half the thickness of a workpiece.

Abstract: 1,196,490. Crimping yarns. MOULINAGE ET RETORDERIE DE CHAVANOZ. 14 Nov., 1967 [14 Nov., 1966 (2)], No. 51797/67. Heading D1F. A helical, fancy yarn of a polyamide, polyester or polyacrylonitrile is continuously produced by winding yarn onto a stationary needle, advancing the coiled yarn along and off the needle and through a heater wherein the coils are heat-set and then cooling the yarn in an accumulator - both the heating and cooling occurring when yarn is relaxed. In the apparatus shown, a yarn 28 fed into the passage 1a of a hollow rotating shaft 1 emerges through one of the ports 2a or 2b, follows longitudinally the surface of a rotating member 2 and is wound spirally on a tapered needle 7 which is magnetically restrained by the magnetic attraction between a pole piece 6 (carried on small shaft 3) and poles (8, 8') of a stationary magnet or magnets. The yarn turns, under the influence of a spring-loaded driven roller 12, are continuously displaced towards the free end of the needle. Coiled yarn passes through tube 10 into a steam heater 11 wherein the yarn deformation is set. On emerging from the heater, yarn passes through tubes 20, 21, into a channel in an element 22 pivoted on a knifeedge 23 and counterbalanced by a weight 24. The coiled yarn accumulates until its weight rocks the element 22 so that a pointed member 26 contacts a mercury bath 27 to close an electric circuit and thereby initiate operation of yarn withdrawal or winding mechanism: when the weight of yarn in the channel has decreased sufficiently, the element 22 rocks (towards an adjustable limit stop 25) to open the circuit.

Abstract: 1,088,599. Classifying granular material. H. RUMPF. Dec. 21, 1964 [Dec. 20, 1963], No. 51907/64. Heading B2H. Material below I mm, in size to be classified is projected in a thin layer at an initial velocity of at least 5 metres per second into a transverse gas current having a velocity of at least 20 metres per second issuing from a nozzle 8 which together with a flow straightener 7 adjusts the gas velocity to be the same over its whole cross-section, the coarse particles being separated from the main gas stream by means of a movable blade 12 by means of which the degree of separation is adjusted. It is stated that with the above velocities, the action of gravity is practically eliminated and separation is effected only by the transverse gas current. The material is fed from a belt 1 onto a conveyor belt 2 and passes in the space between the belt 2 and a wall 3. Auxiliary gas controlled by a throttle 31 is. fed through that space to help in conveying the material into the transverse gas flow. The coarse particles are conveyed to a duct 10 by means of auxiliary gas introduced through a duct 11 and controlled by a throttle 19 and the fine particles pass with the main gas stream through a diffuser 14, the fine and coarse particles being separatedfrom the gas in cyclones 15, 17. In modifications, the direction of projection of the material may be inclined and the direction of flow from the nozzle may be directed downwards or upwards at an-inclination to the horizontal. In a further modification, Fig. 6, the material is fed in a wedge-shaped gap 25 between two belts 2, 23 the belt 23 aiding in the acceleration of the material. Members 22 may serve to scrape the material off the belts. In a still further modification, Fig. 7, the material is classified into three fractions, the size of the particles in each fraction being adjusted by adjusting blades 28, 29 in the directions of arrows 26 or 27. To assist in preventing the coarse particles from rebounding into the main gas stream, flexible walls, e.g. rubber curtains, may be provided which are inclined to the path of the coarse material.

Abstract: 1407061 Tobacco-smoke filter manufacture F J BURRUS & CIE 10 Nov 1972 [10 Nov 1971] 52028/72 Heading A2C [Also in Division B1] Different fluent filter materials, stored separately in two or more distinct reservoirs, are homogeneously mixed during free fall into a loading funnel 8 which opens laterally into a channel through which spaced filter elements 3, 4 are conveyed, to fill the chambers 5 formed by the spaces between successive elements 3, 4 with mixed filter materials, while an upward flow of air through the funnel 8 in the free fall area removes dust particles. A container 9 is divided into two reservoirs by a partition 23 the position of the lower edge of which is adjustable to control the relative proportions of the different fluent materials that pass out of the reservoirs through a square tube 36 and into a mixing tube 37. The tube 37 is provided with baffles 39 and is subjected to suction applied through a tube 43 at its top end. The rate of feed of the fluent materials into the tube 36 is controlled by a rotary device shown in Fig. 3 in response to photo electric detection by a device 11 of the level of the mixed filter materials in the bottom of the funnel 8. The chambers 5 are subjected to suction, applied via a tube 18, prior to filling, and the resultant composite filter rod filler is wrapped and cut as described in Specification 1332423. In another embodiment, Fig. 4 (not shown), the filter materials are first allowed to fall against baffles that take the form of fins helically disposed around a stationary vertical shaft and then pass through a succession of horizontally disposed wire mesh grids in the free fall mixing region.

Abstract: 1,188,569. Mineral-mining cutter drums. AUSTIN HOY & CO. Ltd. 27 Nov., 1968 [27 Nov., 1967], No. 53949/67. Heading E1F. To dilute any dangerous concentration of inflammable gases that may occur around a cutter drum of a mineral-mining machine, when the drum is operating in a mineral seam, a stream of a suitable gas issuing from the outer end of the drive shaft is, by a vane assembly 45, 53, 54, deflected through aright angle and directed to a lower arcuate portion of the periphery of the drum so that, as regularly spaced apertures in the curved periphery of the drum come successively into registry with the stream of gas, the gas can pass outwardly of the drum. The assembly is freely rotatable in bearings 46 disposed coaxially of the drum in the end plate 50 thereof. A weight 47 secured to the assembly biasses the assembly to a position in which the radially extending vanes 53 are directed downwards. The spread of the gas towards the lower arcuate portion of the drum can be varied by appropriately securing closure plates between the inner ends of some of the radially extending vanes 53.

Abstract: 1285347 Spring mechanisms FRANCE ARMED FORCES-MINISTER OF 4 Nov 1969 [5 Nov 1968] 54081/69 Heading F2S [Also in Divisions F3 and H2] A device for use in the launching of rockets to release an "umbilical cord" (containing connections between the launch pad and the rocket) consists of a spring-loaded plunger 3 which is retained in an "armed" state by a latch 6. The plunger is so constructed that it can move out of engagement with the latch and so allow the spring to move the plunger axially, thereby to operate a member 14 to disconnect the umbilical cord. In use a rocket (not shown) has an umbilical cord (not shown) whose connection to the rocket is releasable by movement of the member 14 and it is arranged that during launch, the rocket tends to move the member 14 in a direction perpendicular to the axis (vertical'in the drawing) of the plunger 3. To arm the device a safety bolt 12 is withdrawn, so that the plunger is held in the position shown only by latch 6. The plunger's head 2 is eccentrically mounted in the housing 1 so that there is a clearance between 1 and 2 (as shown, on the right-hand side), and the plunger's stem passes through a swivel 5. In consequence, lateral displacement of the member 14 will move the plunger away from the latch 6 and allow the spring 4 to extend. This will effect a sudden downward displacement of the member 14 to disconnect the umbilical cord. Such disconnection is termed "last instant release", being brought about by movement of the rocket itself. Provision is also made for controlled release, viz. an electromagnet 7 which may be operated to displace the latch 6 out of the housing 1. Microswitches 10, 11 and 13 are provided to signal the condition of the device: 10 and 11 sense the changes between the armed and released positions of plunger and 13 senses the state of the safety bolt.
