Abstract: 368,210. Lubricating valves. KONSTANTINOFF, J., 19, Rue Vernier, Paris. Oct. 26, 1931, No. 29651. Convention date, Oct. 27, 1930. [Class 12 (ii).] In an internal-combustion engine having rotary distributing valves 1 mounted within sleeves 6 in the heads 4 of the engine cylinders 5, oil is fed to the inner surface of each sleeve through ducts 19 from recesses 15 formed in the exterior thereof, the recesses 15 being supplied with oil under pressure by a pump through pipes 18 and being also in communication, through passages 13, 16, with an oil reservoir 12 from which the pump draws and in which the bearings 8, 9 of the valve run. Should the pump fail, lubrication of the valve is thus still ensured by gravity flow from the reservoir. The pump delivers to a manifold 27 in a cover member 24 to which the pipes 18 are connected. Oil is supplied to the worms 11 driving the valves from the manifold 27 through ducts 29. Each valve is provided with packing rings 2, 3 which contact with the sleeve 6 only at their edges, and the ducts 19 lead to annular grooves 22 on the inner surface of the sleeve 6 opposite the contacting portions of the rings.

Abstract: 818,974. Nail extractors. SAINIO, R. L. Sept. 20, 1957 [Sept. 21, 1956], No. 29695/57. Class 61. A machine for extracting nails comprises a pair of jaws 18 carried by a member 8 which is slidable on the upright 2 of the framework 1 by means of a presser 10 pivoted to a connecting rod 4 actuated by a crank shaft 3. The presser 10 is pivoted to the slider 8 and bears against the lifting stop 14 to drive the slider upwardly. One jaw 18 is rigidly secured to the slider 8 and the other to a lever 9 pivoted to the slider. The presser 10 has a cam face which bears against the back of the lever 9 in such manner that downward movement of the connecting rod 4 first produces closing of the jaws against the action of the spring 12 and thereafter moves the assembly downwards dragging the nail out of the board. A brake 7 prevents the slider 8 from moving downwards before the jaws have bitten into the nail. An outlet opening 17 in the frame is provided for the extracted nails.

Abstract: 986,139. Ink-ribbons &c. COLUMBIA RIBBON & CARBON MANUFACTURING CO. Inc. Aug. 18, 1961, No. 29825/61. Heading B6F. [Also in Division D1] An ink-impregnated woven fabric, e.g. an ink ribbon, is formed of woven multi-filament strands of fibre-forming polymer, the individual filaments being longitudinally ridged to provide increased ink capacity in the material. The ridges may be provided by forming each filament with two or more lobes as shown in Fig. 2. Intermeshing of the filaments causes the thickness of the material to be less than that made from circular-section filaments of the same denier. The filaments may be of nylon or other suitable synthetim fibre-forming material such as " Dacron " (Registered Trade Mark) polyester fibre, or " Saran " (Registered Trade Mark) thread. Further, the strands may be composed of from 10-40 filaments of from 1 to 3 denier each, resulting in a fabric of a calliper of between 0À0025 to 0.006 inch.

Abstract: 737,479. Filters. WALLACE & TIERNAN, Inc. Nov. 27, 1952 [Dec. 1, 1951], No. 30119/52. Class 46. A liquid filter element having a substantial dimension in at least one direction has means for trapping gas over an area adjacent to the whole of the effluent side, whereby when the pressure on the influent side is suddenly reduced below that on the effluent side, a sudden evenly distributed reverse flow of liquid occurs. As shown, a tubular filter element 6 comprises a vertical filtering surface 26 having adjacent substantially the whole area of the effluent side thereof a plurality of spaced superposed gas trapping vessels 24 closed at their tops; said gas on suddenly releasing pressure on the influent side of the element 6 causing a reverse flow of cleaning liquid over the surface 26. The filter medium comprises diatomaceous earth supported by a flexible sleeve having slits 29 (not shown) in turn supported by a perforated wall of the element 6. The vessels 24 of each element are bell-shaped with fluted edges 36 to assist flow of filtrate to ports 27 of a central discharge duct 28 leading to a manifold 11a and an outlet valve 11. Release of pressure to effect back-flushing is effected by closing valve 11, a drain valve 10, an inlet valve 14 and a valve 15 used during the building up of the filter bed and also opening a valve 23 so as to release air trapped at the top of a casing 21 enclosing the elements 6.

In a vehicle hand-brake arrangement in which a hand-brake lever 11 is operatively connected by the mechanical linkage 16 to the brakes and a pawl 14 co-operating with a fixed ratchet 15 to retain the brake lever in its various braking positions, a hand grip catch 13 is connected mechanically both with the pawl 14 and with the control valve 24 of a servo braking mechanism such that the grip catch is capable of operating the control valve to cause the application of power braking independently of release of the pawl 14 from the ratchet 15. The pawl 14 is connected with the grip catch 13 through an elastic lost-motion connection 18, 19 by which the pawl 14 can be released only after the grip catch has been placed initially by an amount sufficient to operate the control valve 24 and so cause the application of power braking. Release of the grip catch 13 permits return of the control valve 24 to the brake " off " position just prior to the engagement of the pawl 14 with the ratchet 15. Specification 740,654 is referred to.

Patent GB-887966-A (GB)
Title: Method of apparatus for producing tubular films of thermoplastic polymeric material
IPC: B29C48/03
Filed: 1960-09-07
Abstract: In making tubular films by melt-extruding an organic thermoplastic polymeric material through an annular die in the form of a tube which is then inflated and subsequently flattened to confine a bubble of gas within the tubing, the inflated tubing p  is cooled to below its solidification temperature by surrounding it with a cooling gas in an enclosed zone through which the gas flows.  The rate of flow, temperature and direction of flow of the cooling gas are such as to cause the tubing to solidify close to the die and to reach its set condition when it has been inflated to its predetermined diameter. As shown, the molten polymer is extruded through the annular orifice of a die 18 to form a tube 22 which is inflated by means of a gas introduced through an orifice in the centre of the die as the tube is withdrawn from the die and collapsed by a pair of rotating squeeze rolls 24, 26.  The rolls and the tubing from the point of extrusion to a point beyond the rolls are enclosed within a chamber 40 through which chilling air is <PICT:0887966/IV (a)/1> circulated.  The flattened film 28 is withdrawn through a slot 41 in a side wall of the chamber 40.  Air chilled by a refrigerating unit 44 is discharged through conduit 48, header 78, ducts 80 and nozzles 82 on to the working surfaces of the squeeze rolls 24, 26. Air chilled by a second refrigerating unit 42 is discharged on to the tubing 22 near the die 18 by way of conduit 46, header 56 and a pair of flexible ducts 58 connected to an air ring 60 which encircles the discharge end of the die 18 and projects into the chamber 40 through an opening 62 in the base thereof.  The air ring contains a plenum chamber 64 into which the chilled air is conveyed from the ducts 58 and from which it flows through a labyrinth 73 to a disc-shaped space 71 between rotatable plates 68, 75.  The inner periphery of plate 75 forms an annular nozzle 70 closely encircling the tube 22.  The plates 68, 75 are rotated about the axis of the inflated tube 22 by an electric motor through a V-belt 74 and a sheave 76 fixed to the plate 75.  Air discharged from the air ring 60 and the nozzles 82 is continuously withdrawn from the chamber 40 through four exhaust ports 84 connected to a pair of ducts 86, 88 for return to the refrigerating units 42, 44.  The invention enables production rates to be increased without adversely affecting the quality of the film.
