Abstract: 888,062. Pneumatic conveyers. SIMON HANDLING ENGINEERS Ltd. Jan. 14, 1960 [Jan. 16, 1959], No. 1705/59. Class 78 (1). In conveyers of the type in which granular material is fed into the air stream by a screw conveyer a, an elastic sleeve c is secured to the end of the conveyer casing b and prevents flow of material into the air stream until the pressure produced by the screw overcomes the resistance of the sleeve and forces apart its lips and allows the material to pass between them. As shown, the air stream is supplied via controllable valves u, t. In a modification (Fig. 2, not shown), the air stream is supplied through a pipe which is coaxial with the conveyer a. In a further modification (Fig. 3, not shown), the screw conveyer and sleeve c open into a conduit which joins at right-angles with a pneumatic supply conduit. The sleeve c may be moulded, or may be fabricated from two pieces of flat elastic sheet material, the edges of which are butt-jointed.

A holder for a cartridge ampoule comprises end portions secured together, one of them being of such construction as to permit the cartridge being placed in position without its needle, 'or discharge orifice, coming into contact with the holder, so that sterilisation of the holder is unnecessary. In the form described the end members 10, 11 are connected by rigid side members 12. The lower member 11 carries a plunger rod 15 and the upper member 10 has a nosepiece divided along a central plane into two halves 21 which are pivoted to it, so that when they are turned outwards, the cartridge 13, carrying its needle 19, may be inserted. The two halves of the nosepiece are then closed together and retained by sliding a ring 27 upwards around them. If the needle is initially enclosed by a frangible cover 25 this can then be removed. The holder may be adapted to take cartridges of differing lengths by the insertion of rubber packing pieces 14 or spring members. Specification 728,816 is referred to.

Abstract: 585,077. Billet-piercing. STEWARTS & LLOYDS, Ltd., and PROTHERO, E. G. Jan. 24, 1945, No. 1870. [Class 83 (iv)] Dies.-In a billet-piercing press the die has a sleeve or liner of less length than either the die or the billet and the sleeve is so arranged as to be withdrawn as the advancing punch pierces and expands the portion of the billet projecting above the sleeve. The opening of the die 12 is of circular cross-section and receives an annular sleeve 10 carried by a lower crosshead 11. The billet 14, also of circular crosssection, fits within the sleeve with its upper portion projecting and its lower end resting on an insert 25 carried by an ejector 13. On the descent of the mandrel or punch 18, the upper projecting end of the billet is pierced and expanded to fill the die space and when the cross-head 15 engages the upper ends of thrust tubes 20 the cross-head 11 is pushed down against the action of resilient or frictional retaining means and so withdraws the sleeve 10 as the punch advances through the billet. The die may be provided with inclined openings 23 for the removal of scale. The ejector insert 25 and supporting column 24 are of approximately square section so as to leave passages within the sleeve 10 also for the discharge of scale. Before the withdrawal of the punch, a stripper plate may be inserted beneath the shoulders 28 on a fixed part of the press.

Title: Method and apparatus for carrying out electrochemical gas reactions
IPC: B01J19/08
Filed: 1921-01-17
Abstract: 158,250. Spiel, H. July 19, 1917, [Convention date]. Gases, treating with electric discharge. - In carrying out electrochemical gas reactions, a stream of an absorbent liquid such as water or a solution of acid or alkali, forming one or both electrodes or an auxiliary electrode, flows continually through and out of the reaction space, thereby removing one or more products. When electrolytic decomposition of the liquid would be prejudicial, alternating currents of frequency higher than 500 cycles per second, say 1000-3000 cycles, may be employed. The liquid may flow through a vertical arcing electrode a and fall as a rapid succession of drops on to a flat dish of liquid b forming the second electrode, an intermittent arc being produced. By increasing the arc gap and the rapidity of flow, a flame arc burning around the liquid jet may be obtained. Specification 16224/09 is referred to.

[Class 89 (ii)] [See also Group XXXI] The disengaging member of an automatic coupling for vehicles comprises an eccentrically mounted hook and a spring-pressed bolt having two surfaces of different inclinations, one of which immobilizes the hook during connection and the other of which engages a pawl on the hook to prevent engagement of the bolt with the hook preparatory to disconnection, Fig. 3 shows an arrangement in which the hook 3, pivoted at 4, is housed in a casing 1 mounted on a rotatable platform 17 on the towing vehicle, and engages a bar 2 on the towed vehicle, the hook being held stationary by the bolt 10. To effect disconnection, the bolt 10 is withdrawn by the handle 15 whereby the pawl 7 is raised by its spring 9 and abuts the surface 12 of the bolt to prevent return of same. The bar 2 is then brought into contact with the side 51 of the hook, either by forward movement of the towing vehicle or by recoil of the towed vehicle, to rotate the hook clockwise and permit disconnection, Fig. 1. To effect connection, the part 2 is moved into the notch 5 by relative movement of the vehicles and the hook 3 rotated anticlockwise. The pawl 7 is moved by contact with the bolt to the position in Fig. 3 and the hook locked by the bolt. The bar 2 is fixed to the limbs of a fork 25, Fig. 7, which is held by a pivot 24 between a fork 23 having an integral cylindrical part 24<1> engaging in a socket 21 on a traction triangle 22, withdrawal of the part 24<1> being prevented by a lock nut 24<11>.

Relates to heating systems for motor vehicles of the kind in which air is heated in an auxiliary radiator which receives, by means of an engine-driven rotary pump, hot liquid from the engine cooling system. According to the invention, a two-part pump is employed, one part (Fig. 1) delivering liquid to the cylinder head or jacket 13 from the bottom of the main radiator, and the other part 2 circulating hot liquid from the cylinder head through the auxiliary radiator and back to the cylinder head. In the form shown, a twopart pump of the impeller type has a stator 9 and a single rotor with two sets of vanes 1, 2. The vanes 1 draw liquid from the tank bottom through pipes 5, 6 into a chamber 10 for delivery to the cylinder head 13 through ports 8 and passages 11, 12, Fig. 2. The vanes 2 draw hot liquid from the cylinder head through a passage 16 to a chamber 15 and deliver to the auxiliary radiator through pipe 17, twoway valve 21 and pipe 18 ; this liquid returning to the cylinder head. The valve 21, which may be remotely controlled, serves to cut off the supply to the auxiliary radiator and byepass the liquid to the cylinder head.
