Title: Multi-port valve
IPC: F16K11/085
Filed: 1963-12-24
Abstract: 1,057,930. Valves. C. E. KIRKWOOD, and B. M. MORONEY. Dec. 24, 1963 [Jan. 18, 1963], No. 50929/63. Heading F2V. A multi-port valve comprises a tubular body member 12 closed at each end and having a plurality. of fluid communicating openings 26 in a tubular wall thereof, a rotatable gate member 24 extended axially within the tubular body member being adapted to divide the interior of the body member into two substantially equal compartments, the gate member being axially supported in the body member and adapted to be rotated by means of a handle outside the body member. In Fig. 3, the gate member comprises a parallelsides axial main portion with a semicircular portion at each end. The periphery of the member formed is in fluid-tight engagement with the walls 36 of the body member, and is provided with two continuous gasket members each supported in a continuous groove. Leakage between the two compartments formed can be detected by opening a test valve 56 in communication with the region between the two gaskets. The valve body preferably has four openings and fluid flow between these may be controlled by the gate member 24 as shown by the two positions of the member (plain and dotted) shown in Fig. 2. As an alternative, the semicircular end portions of the gate member may be replaced by circular end portions with the same gasket arrangement as before, or incorporating four gaskets as shown in Fig. 7. An arrangement of a six port valve is shown in Fig. 10, in which two positions of the gate member are drawn giving two flow variations. The thickness of the axial section of the gate member is such that it is thinner than the diameter of the ports, resulting in continuous flow during rotation of the gate member.

Abstract: 1,007,070. Knives. H. J. STOLBACH. Dec. 27, 1963 [Jan. 10, 1963], No. 51067/63. Heading B4B. A slicing knife 14 is provided with an adjustable guide 26 comprising a block 33 having a surface contacting the knife handle 12, the handle-contacting surface being formed with a shoulder 34 engaging a shoulder 38 on the handle. The handle has a cavity 40 which receives an extension 42 of the block 33, an adjusting screw 46 to which a knob 56 is secured having a threaded shaft 44 engaging a threaded opening 42a in the extension 42. The shaft 44 is held axially in seatings 48, 50 in the handle 12 and is held against lateral movement in the handle by means of a releasable slide 58 having an opening 62 the width of which is greater than the diameter of a reduced portion 52 of the screw 46 but less than the diameter of a pair of shoulders on either side of the portion 52. The slide has a larger opening 64 to facilitate release of the screw 46. Reference has been directed by the Comptroller to Specification 745,170.
Patent GB-510685-A (GB)
Abstract: 510,685. Steam cooking-apparatus. ALLIED IRONFOUNDERS, Ltd., and PERCY, J. G. Feb. 3, 1938, No. 18335/39. Divided out of 510,608. [Class 28 (i)] In a cooking-apparatus having a chamber 1 to which steam is admitted or from which steam is vented under the control of a three-way plug cock 11, the cock is operated by manual means so arranged that the door 1b cannot inadvertently be opened when the cock is in the steamadmission position, and when the door is open, the cock cannot inadvertently be moved to the steam-admission position. The cock 11 is operated by a handle 13c on the squared end 13b of a shaft 13, the other end of which is squared at 13a to slide in a socket 14 on the plug of the cock. A stop member 16 is secured to the shaft 13 to limit the turning angle to 90 degrees, and to serve as an abutment for a spring 17 and a distance piece 16a. The spring 17 tends to slide the shaft 13 inwardly to engage the quare 13b with a square hole 15a in a flange 15 forming a part of the oven casing. This prevents the handle from being turned until it is pulled out to disengage the square from the hole in the flange 15. The means for securing the door 1b in closed position may comprise sliding wedge bolts, and one of these is provided with a peg 18 which engages a slot 13e in the handle so that the bolts cannot be displaced from their door-locking positions until the handle 13c is pulled out.
Patent GB-510974-A (GB)
Abstract: 510,974. Delivering materials from hoppers. C.U.R.A. PATENTS, Ltd., (formerly C.A.M.A. PATENTS, Ltd.), and SCANES, J. J. March 2, 1938, No. 6581. [Class 78 (i)] [Also in Group XI] A fuel container 1 having a single orifice 3 has a closure member comprising an apertured shutter 9 furnished with bent-over edges 11 which take over flanges 12. Sliding of the shutter brings its aperture into or out of register with the orifice 3 to permit of entry or exit of fuel. A similar shutter 10 is provided at the lower opening of a charging hopper 15, and the hopper and receptacle may be held together during the transfer of fuel by pivoted arms 6 taking over lugs 8 on the receptacle. Other attachment means, such as a screw or a bayonet joint, may be employed. The hopper 15 may have a device for charging the container 1 with measured quantities of fuel, and this may take the form of a chamber 16 provided with a window 18 and divided from the hopper 15 by an apertured slide 17. Alternatively a rotary cylinder having a slot parallel to its axis may close the bottom of the hopper, and in the further form shown in Fig. 6 the hopper has two superposed apertures 22, 23. The fuel falls in cone formation through aperture 22 on to a channelled tray 24 from which it is pushed by a reciprocated plate 25 mounted on arms 26. The fuel thus repeatedly drops through the aperture 22 to form a cone on the tray 24 and is forced aside to fall down through the lower aperture 23 into the container 1.

Title: Gun with recoiling barrel and transersely moving breechblock
IPC: F41A3/10
Filed: 1968-11-12
Abstract: 1374755 Gun RHEINMETALL GmbH 12 Nov 1968 [5 Dec 1967] 53705/68 Heading F3C A gun has a recoiling barrel 1 provided with a bottom plate 4, a base breechblock 5 embracing the bottom plate 4 and displaceable transversely of the barrel 1 in the central vertical longitudinal plane of the latter, a pair of rollers 6 projecting laterally one on either side of the breechblock 5, and a corresponding pair of fixed inclined guide tracks 7 disposed one on either side of the barrel 1 so that opening of the breech is caused as the rollers 6 ascend the tracks 7 during return movement of the barrel 1 after recoil. In the open position of the breechblock 5, as shown, the counter-recoil movement is almost complete. In this position, which is reached when the highest point on the ascending curve 8b of the guide tracks 7 is occupied by the rollers 6, the counter-recoil movement is arranged to be halted for a brief period and a shell 12 is positioned by means of an automatic loading device 11. The rollers 6 then follow the steeply descending curve 8c as the residual forward travel of the barrel 1 is completed, so that the barrel is closed at the rear by the breechblock 5 which drops down, whereafter the shot can be fired. The resultant recoil causes the barrel 1 together with the breechblock 5 to move rapidly rearwards, the rollers 6 being moved along horizontal guide grooves 9 causing switches 8d forming the lower portions of the curves 8b of the guide tracks 7 to rise. The rollers 6 come to rest on short straight sections 8a of the guide tracks 7 at the completion of recoil. Before firing, a fresh shell 12 is fed to the automatic loading device 11. Without any interruption, the barrel 1 together with the breechblock 5 is now moved forward by a tensioned counter-recoil mechanism (not shown) and the above operation repeated. The breechblock 5 is coupled to the bottom plate 4 by levers 16 secured to torsion springs 13, 14 arranged side by side in the bottom plate 4 transversely of the barrel axis and clamped each by one end only at opposite sides of the barrel 1. The levers 16 are guided in grooved bars 17 secured to the underside of the breechblock 5. While the breechblock 5 is being raised when the barrel 1 moves forward, the springs 13, 14 are put under stress, so that the closing operation which takes place automatically due to the weight of the breechblock 5 is reinforced by the tensioned springs.
