Title: A lubricant dispenser for attachment to a sewing machine
IPC: D05B71/00
Filed: 1960-09-13
Abstract: 968,841. Lubricating. M. S. ABRAMOWICZ. Sept. 13, 1960 [Sept. 22, 1959; Aug. 3, 1960], No. 29804/60. Heading F2A. [Also in Division D1] A dispenser for supplying lubricant to a bearing of a sewing-machine or the work being sewn thereby (see Division D1) has a valve operable by the vibration of the machine when running to control the flow of lubricant. The reservoir 2 has a passage 17 communicating with a tube 4 pivotally mounted in the housing 5 and urged downwardly, when the tube is lowered from the position shown in Fig. 1, by a spring. A ball 16 seated on the passage 17 prevents the flow of lubricant except when the machine is running, when the vibration of the machine causes the ball to chatter on its seat. In another embodiment for use with volatile liquids a similar ball valve is provided at the top cap of the reservoir. In a third embodiment for use with viscous fluids a ball valve is provided only at the top of the reservoir to regulate the fluid flow by controlling the flow of air into the reservoir.

[Also in Group XXVII] A crankoase breather for an I.C. engine comprises filter material 3 disposed in the space between two inverted cup-shaped members 1, 2, perforations through which air can pass being formed in the top 7 and in a flanged rim 5 of the inner member 1, and a U-shaped spring 10 adapted to enter the access neck of the crankcase having arms 9 extending through slots in the top of the member 1, and a part 11 disposed between the tops of the members 1, 2, the spring 10 being resiliently gripped between the members by deformation of the spring or of one of the members. In Fig. 1 the resilient grip is provided by semi-circular portions on the part 11, the diameters of which are slightly greater than the distance between the tops of the cups. In Fig. 3 (not shown) the spring has an undulation the height of which exceeds the distance between the tops of the cups, the top 7 having two slots for the arms of the spring and two breathing slots. In Fig. 5 the top of the member 1 has a hemispherical deformation 7 resiliently bearing against the top 11 of the spring 10, and in Fig. 7 (not shown) the spring is made of round wire and the part 17 has a groove to locate the wire against the top 4 of the cup 2. The outer cup 2 may have indentations 23, Fig. 11, protruding inwardly so as nearly to meet the wall of the inner cup, whereby the filter material is retained in position.

Abstract: 1371741 Conveyer systems BAKELITE XYLONITE Ltd 20 Sept 1971 [19 June 1970] 29881/70 Heading B7L [Also in Division B8]  A transport apparatus for the conveyance of articles comprises a plurality of carriages 3 each of substantially "G-shaped" cross-section mounted so that each carriage rides on wheels 4, 5, 6, 7 which bear upon an endlegs rail 1 disposed wholly within the C-section, the arrangement being such that the wheels prevent rotation of the.carriage about three mutually perpendicular axes, each carriage being linked to the two adjacent carriages to form an endless chain and means for driving the carriages along the rail. The carriages are linked together by links, e.g. 13, 23 which are pivoted at one end to the carriages, at the axle 8 of the wheel 4, and at the other end to each other, via pin 20, to form the chain which can thus be folded zig-zag fashion. Pin 20 may be provided with wheels 21, 22 which co-operate with a track (not shown) which varies in distance from the rail 1 in order to cause the chain to fold up or straighten out and thus cause carriages 3 to travel slow or fast. The carriages are driven round the rail by means of a sprocket which engages with the ends of the axles 8 at any suitable point of the rail but is preferably located at a point where the rail curves through an angle of at least 90 degrees as this makes it easier to engage the sprocket.

Filed: 1962-08-04
Abstract: Technical sulpholane is purified by treatment with an oxidizing salt. Salts indicated are permanganates e.g. potassium permanganate, or chromates e.g. sodium chromate or dichromate. Treatment with potassium permanganate is preferably continued until it is in excess, the excess is removed with methanol, purified sulpholane being recovered after distillation of water and removal of potassium and permanganate ions on an ion exchange column. Temperatures of 40-60 DEG C. are used.  Examples are provided. The treatment removes undesirable odour and colour from the technical product.

Abstract: 827,987. Variable resistances. ACTON LABORATORIES Inc. Oct. 3, 1956 [Feb. 24, 1956], No. 30164/56. Class 37. Figs. 1 and 2 show a variable resistor comprising a deposited film 24 of resistive material on an insulating base 23 with silver terminal members 25, 26. Superimposed upon the member 23 is an insulating gasket 27 and a resilient metal plate 28 which may be a thin sheet of coin silver, an alloy of precious metal or beryllium-copper plated with rhodium. Further superimposed upon this sheet is a resilient sheet 29 of insulating material such as a plastic impregnated woven fibre glass sheet, " Teflon " (Registered Trade Mark), impregnated fibre glass cloth being preferred. A threaded shaft 14 rotated by shaft 13 carries a contact carrying member 17 supporting a pressure foot 18. As shown in Fig. 4 the foot comprises a single sheet of resilient metal having two guiding portions 33 and a central resilient portion 34 which carries a dimpled member 35. Contact 35 presses upon the fibre glass member 29, thus moving the adjacent metal foil 28 into contact with the resistance element 24. Figs. 5 and 6 show a variable resistance having a circular track 56 of resistance material in an insulating base 55, two annular washers 61 and 62 spacing from it a metal foil ring 63 and superimposed upon this is a plastic impregnated fibre glass member 64. The rounded tip of a spring 46 mounted on arm 44 deflects the metal foil 63 so as to make contact at a selected point on resistance strip 56. The resistance assemblies are hermetically sealed by suitable adhesive such as epoxide adhesive applied between the edges of the lower insulated resistance supporting plate and the upper resilient fibre cloth member. Terminal members are brought out from each end of the resistance element and from the metal foil.
