Abstract: 482,815. Porous impregnated paper. MINNESOTA MINING & MANUFACTURING CO. June 27, 1936, No. 9199/38. Convention date, June 29, 1935. Divided out of 482,575. Drawings to Specification. [Classes 96 and 140] A sheet or strip of paper is uniformly impregnated with a binding agent and afterwards treated so that at least one face is left in a porous condition. The binding agent is preferably glue or a glue-glycerine composition in aqueous solution. After impregnation the sheet is dried under such conditions of temperature and humidity that the water is removed while the binding agent is in a liquid or plastic state, so that the pores of the product are not completely filled. Suitable relative humidities range from 90 per cent to 15 per cent with temperatures from 100 to 200 F. The paper is preferably an unsized paper and may be crÛped or towelled. One side of the backing may be subjected to further impregnation and dried so as to form either a sealing or porous layer. The paper is then passed through a formaldehyde bath to insolubilize the glue. Apparatus for carrying out the process is described similar to that described in Specification 425,151. The use of the product as a backing for adhesive tape is described in Specification 482,575. U.S.A. Specification 1,923,631 also is referred to.

Abstract: 493,286. Shoots and hoppers. GIMSON & CO (LEICESTER), Ltd., and CLARKE, A. April 1, 1937, No. 9325. [Class 78 (i)] [Also in Group XVII] An automatic feeding mechanism for screw stoppers and similar headed closures comprises a hopper, reservoir or magazine 4 from which the closures are dispensed head downwards, a track 10 into which the closures are delivered, and conveyor means such as discs 8, 9 or a single disc or an endless conveyer, adapted to engage frictionally the underside of the heads of the closures, the track and conveyer means being so constructed and arranged that the closures are transmitted in the inverted position to a point where the closures are taken as and when required, in particular, to a closure-applying mechanism A. The track may be straight, or it may be curved as shown, in which case it in part embraces the delivery side of the magazine ; the track consists of side members 10 shaped to engage the shanks of the closures and so arranged with respect to the conveyer discs as to permit the passage of the heads of the closures. The discs may be geared together, as shown, the edges of the discs being toothed for this purpose, and the disc 9 is carried by a shaft 17 in driving connection with a gearwheel 22 in gear with a fixed wheel 18, so that as the bottle-supporting table 19 rotates, the discs 8, 9 are also put in rotation. Mounted within the hopper 4 is a drum 1 open on its underside and provided on its periphery with a number of pockets 2 open towards the interior and also towards the exterior but closed by the walls of the hopper except at those points which are adjacent to the track 10. The drum is driven from a convenient shaft on the machine or by a separate electric motor ; and a second hopper and drum may be arranged adjacent to the first hopper and delivering closures into the same track. Any closures which jam in the pockets of the drum are freed as the drum rotates by means of a spring-pressed arm. From the track 10 the closures are delivered to a magazine 31 supplying the stopper-applying mechanism A and comprising a wheel 31 having on its edge recesses 32 adapted each to receive at the point adjacent to the end of the track 10, a stopper, and to carry this, as the wheel rotates, to the highest point where the stopper is picked up by the stopper-applying mechanism A. The wheel 31 is rotated by ratchet mechanism 35 moved forward step-by-step by means of a vertically-moved bar 36 actuated by a convenient part of the machine.

Abstract: 1472847 Diesel operated pile drivers DELMAG - VERWALTUNGSGESELLSCHAFT mbH 6 March 1975 [13 March 1974] 9374/75 Heading B3H In a diesel operated pile driver in which fuel is injected on to an impact surface of an impact member and is subsequently atomized by the impact of an opposing face of a piston on the impact member, two or more fuel injection nozzles are arranged in the casing of the pile driver so that the discharged jets of liquid fuel impinge upon one another at the impact surface of the impact member to substantially destroy the kinetic energy of the liquid fuel flow. The pile driver may have three fuel nozzles at angular spacings of 120 degrees about the longitudinal axis of the casing or at least one pair of opposed nozzles. In the preferred embodiment a pair of opposed nozzles are located beneath a fuel pump driven off the reciprocating piston and their jets make an angle of 20 degrees with a line 14a parallel to the casing's longitudinal axis. Each nozzle comprises a valve member 60 urged against its seat 58 by a helical 62 put lifted therefrom periodically upon fuel pressure acting on a surface 64 of the valve member 60, the fuel entering the nozzle via a pipe 30 and duct 52. Two exhaust ports are located above the two nozzles and both ports are on the same side of a diametral plane passing through the two nozzles. Specification 1,328,173 is referred to.

[Class 78 (i)] [Also in Group II] In apparatus for the pneumatic conveying of pulverulent or granular material a feeding receptacle for the material, the conveyer tube, and an air inlet tube are connected by coaxially-arranged swivel junctions so as to permit each of the members to swing in any direction about the common swivel axes of the junctions. As shown in Fig. 5, the feed system 7 is rotatably mounted on a feeding pipe 15 and has connected to swivel a pressure conveyer pipe 8. An air pipe 9 is connected to an air chamber 16 surrounding the pipe 15 and pressure pipe 8 and serving as an air supply chamber for the pipe 8. The chamber has two rotatably-connected parts 16a, 16b, the first is stationary and connected to pipe 15, the part 16b is movable and is rigid with the pressure-pipe 8.

[Class 38 (v)] In a retractive switch suitable for transmitting signalling impulses, a ratchet and pawl 23, 24 are arranged so that, once the handle 28 has started to move, it must finish its stroke and complete the impulse before it can be reversed. The handle 28 rotates a shaft 3 which drives an insulating drum 4 by a pin-andslot connection 6, 7, against the bias of springs 17, 18, to the " on " position where a segment 5 on the drum bridges contact strips 8, 9. The ratchet 23 is fixed to the shaft and cooperates with the pawl so that the direction of movement of the shaft cannot be reversed until the pawl has traversed the entire length of the ratchet, i.e. until the switch is " on." The handle 28 has a pin-and-slot connection with a sleeve 30 surrounding the end 29 of the shaft so that it may be removed only when the switch is open. In a modification, Fig. 2 (not shown), the drum is eccentrically mounted and on rotation causes contacts on spring blades to engage. In a further modification, Fig. 3, a rectilinearly movable shaft 44 and drum 51 carry a contact disc 43 which bridges contacts 47.
