Title: Improvements in or relating to flexible passage or chute
IPC: F41A9/57
Filed: 1945-03-28
Abstract: 604,291. Ammunition shoots. HUGHES TOOL CO. March 28, 1945, No. 7840. Convention date, May 13, 1944. [Class 92 (ii)] [Also in Group XXX] A flexible passage or shoot for guiding a flexible member particularly for guiding belted ammunition towards a gun, comprises a number of transverse elements 30, Figs. 1 and 11, each shaped to the configuration of the passage, means for linking the elements for limited movement towards and away from one another, and a plurality of guide members 60, each of which has an attachment portion 64 bounding a part of the passage and a memberguiding land 67 extending into the passage in guiding and frictional relationship with said flexible member. Referring to Fig. 9, which shows a transverse element in a partly completed condition, a frame 33 of wire is bent to the general configuration of the shoot. The base of the frame is depressed at 41, (see also Fig. 5), to ensure a clearance between the frame and the links 23 of an ammunition belt which is to be guided to a gun 17, Fig. 1. Within each U-shaped side portion of the frame is disposed an attachment member 43 which is formed of sheet metal and which is shaped to contact the corresponding faces of the frame. Each member 43 is formed with tabs 50, 50<SP>1</SP>, which are deformed as shown to secure the member to the frame, with inwardly directed hooks 49, 49<SP>1</SP>, and with three extensions 51, 511, forming links. To this structure is attached, as shown in Fig. 11, a pair of guide members 60, also of U-shape, these being welded at 65 to the members 43. Each member 60 has its opposed walls 62 deformed inwards to provide a land 67 such deformation leaving a cavity between members 60 and 43. Each land also provides an extension 70 which projects along the adjacent link 51<SP>1</SP>. The side wall of each guide member is spaced from the side wall of the attachment member to provide a further cavity 73, and has an extension 72. When assembling elements thus constructed to form a shoot the extensions 70, 72, and the corresponding links enter the cavities of an adjacent element and the hooks 49, 49<SP>1</SP> and the links spring outwards into resilient engagement with each other. Such a connection between the elements enables the shoot to flex in all directions, and to contract in length. The end of the shoot is secured to the gun by a rod 86 passing through lugs on the gun and on a member 80 at the end of the shoot. This member 80 is formed at each side with a channel 90 each of which houses a slidable locking member 94 adapted by means of a keyhole slot, to engage and hold a rivet head 110 suitably secured to the end of the shoot.

Title: Improvements relating to retractable undercarriages of aircraft
IPC: B64C25/22
Filed: 1940-05-10
Abstract: 539,128. Retractable aircraft undercarriages. HAERLE, H. R. May 10, 1940, No. 8435. [Class 4] [Also in Group XXIX] The retraction mechanism of an aircraft undercarriage is controlled, so that retraction can only be effected after the aircraft has reached a predetermined air speed, by means of a fluid operated device coupled to the operating mechanism by valve or relay means. The control may be applied to the hydraulically or electrically operated systems of the retraction mechanism, the circuits in either case being interrupted until the above condition is fulfilled, or it may be applied to the control members of either of these systems whereby such members are kept in a locked position until the predetermined air speed is reached. In an embodiment of the former application, a fluid supply line of a hydraulically operated system is provided with a valve 5 arranged between inlet and outlet passages 2a, 8 respectively, the valve being housed in a lower enlargement of a housing 1 which latter also accommodates a piston 13 in an enlargement 3. Both the valve and piston are spring urged in the same direction and their stems contact so as to move together. The parts 2a and 3 communicate through passages 21, 22 via a relay valve comprising a ball 19 spring urged on to its seating at the base of a cylindrical bore 17, the ball contacting with a rod 20 accommodated in the latter. Supported on the housing 1 is a cover 23 housing a bellows 24 normally expanded by a spring 28 and an adjustable screw 26, the bellows being connected by a pipe line 27 to a source of negative pressure on the aircraft. The latter may be obtained from a venturi or the pressure difference between the upper and lower surfaces of the wing aerofoil by accommodating the casing of the bellows or diaphragm within the wing and when this reaches a sufficient value according to the speed of the craft, the bellows collapses and through linkage 30 and rod 20 forces the relay valve 19 off its seat thereby connecting the inlet 2a to the cylinder 3. The valve 5 is thereupon lifted off its seating and the fluid line of the retracting system restored to continuity. In a form of the invention applied to the control member of an electrically operated system, the fluid responsive device comprises a two-part casing 31, Fig. 2, with a diaphragm 32 held there-between, the upper part being connected by a pipe line 34 to a venturi 35 mounted for example on the undercarriage 36. A spring 38 and adjusting screw 37 are provided. The lower part of the casing houses a fixed contact 39 and a pivoted contact 40 movable by a rod 41 so that flexure of the diaphragm upwardly causes the contacts to be closed. The latter are in circuit with a solenoid 42 which is adjacent to the control member 43. When the contacts are open the catch 44 locks the control member in the " down " position as shown, the catch unlocking when the contacts are closed. Specification 538,700 is referred to.

Filed: 1927-03-28
Abstract: 278,307. Commercial Solvents Corporation, (Assignees of Legg, D. A.). Oct. 1, 1926, [Convention date]. Bacteria, cultivating.-A process for rendering butylacetonic bacilli immune from epidemics of sluggishness consists in repeatedly subcultivating the bacilli in the presence of the filtrate from a sluggish fermentation, the culture being " heatshocked " at each transfer. A sterile carbohydrate mash is prepared and inoculated with a spore culture of butyl-acetone bacilli. It is then heat shocked, for instance by being raised to 100‹ C. for three minutes, to destroy vegetative cells, after which one or two drops of filtrate from a sluggishly fermenting mash is added. The filtrate is obtained by first removing all solids and then passing through a Berkefeld filter to remove bacteria. Fermentation is allowed to proceed until spores are developed. This spore culture is used to inoculate a fresh mash and the process is repeated, usually about ten times, until an immune culture is obtained. The immune bacilli are used in the production of acetone and butyl alcohol bv the fermentation of amylaceous and saccharine carbohydrates in the usual manner. Specification 4845/15, [Class 14 (ii), Beverages &c.], is referred to.
