Title: Improvements in leg structures for mounting aircraft landing elements
IPC: B64C25/00
Filed: 1942-07-22
Abstract: 565,052. Aircraft undercarriages. DOWTY, G. H. July 22, 1942, No. 10274. [Class 4] An aircraft landing element mounting comprises a box strut made of sheet material and a resiliently deformable articulated frame extending therefrom for connection to a landing element. As shown, a tapered channel- Section member 8 of sheet steel is welded to another sheet steel channel member to form a hollow box section which is strengthened at intervals by internal diaphragms 11, 12, 13. A lever 18 carrying a landing-wheel axle at its rear end is pivoted within the lower end of the member 8 and is connected at an intermediate point 23 to a shock-absorber 22 anchored to a pivot 24 extending across the member 8. The sides of the member 8 between the pivots 19, 24 are strengthened by thicker plates 25 welded thereto. These plates are extended forwardly as shown at 26 to provide anchorage for a tractor cable, and rearward extensions 27 form attachments for a jointed strut or other device for retracting the mounting. The upper end of the member 8 is plugged by a fitting 14 which is pivoted to the airframe. A machined spacer may be used to strengthen the strut near the pivots 19, 24. A standard fitting may be cut shorter from the top before fitting the end plug to suit a smaller aircraft. For large aircraft, two such members 8 are braced together by transverse plates secured to brackets 17 and the two levers 18 support the ends of the axle of a wheel placed between them. Fig. 7 shows a cross-section of an alternative construction comprising two identical stampings 31 welded together at 32. According to the Provisional Specification light alloy stampings may be used.

Title: Corner clips for detachably connecting sheets of paper together
IPC: B42F1/12
Filed: 1943-06-25
Abstract: 572,203. Paper fasteners. LAEVENBUK, S. June 25, 1943, No. 10323. [Class 44] Paper clips for securing sheets together at a corner and of the kind folded over to sandwich together the sheets and fastener, are provided with a suspending or positioning loop. Fig. 1 shows one form of clip before use. The superposed corners of the sheets are placed on part b, and the corners a, a2 are folded down along the diagonal lines. The part g is bent up to provide the suspension loop, the tongue c being folded down behind so that the completed connection is as in Fig. 2. The tongue c may be semicircular or of any other convenient form, and may have one or more perforations so that either the part c or the part g may be bent up to provide the suspension means. Fig. 12 shows one of a number of alternative forms described, and has a substantially rectangular tongue c with two perforations f, the part g being of similar shape. In this embodiment the folding is effected on parallel horizontal lines, a slot e being provided at one of these lines in which the corners of the papers are inserted before folding. Generally, the clip is of sheet metal, but it may be of paper layers with interposed wire or metal strip reinforcement. The reinforcement may project beyond the edges of the paper layers and be formed to provide the suspension loop.

Title: Improvements in or relating to straining presses
IPC: B30B9/06
Filed: 1921-04-08
Abstract: 184,225. Schnieder, P. April 8, 1921. No Patent granted (Sealing fee not paid). Fats and fatty oils, extracting by pressure. Apparatus for extracting oil from seeds comprises a main hollow plunger E, a fixed piston L therein, hollow plungers G communicating through passages F with the interior of the plunger E and moving in cylinders J rigidly connected to the container H in which the plunger E moves. The interior of the plunger E and of the plungers G is in constant communication through the hollow rod C of the piston L with a source of low pressure. On connecting a chamber A to high pressure the plunger E moves into the container H and oil is expressed through the press plate K on the end of the plunger and the press plate K<1> which forms the end of the cylinder. On release of the high pressure, the low pressure within the plunger E causes the latter to withdraw. Catches M pivoted on the plunger E engage pins O on the container H so that the container is withdrawn with the plunger and the cake is allowed to fall from the plate K<1>. The lateral walls of the container H are tapered so that the cake does not adhere to the plate K, when the latter is withdrawn. When the catches M come into engagement with abutments N they are released from the pins O and the low pressure in the plungers G and cylinders J causes the container H to return to its closed position. The release of the cake from the plate K<1> is effected by a plate R forming the centre of the plate K<1> and attached to a plug Q pushed forwards by a transverse bar P which moves with the container H. Helical keys on the plug Q give a slight rotational movement to the plate R. The cover T of the container H has attached to it a filling gauge V, and the cover is moved manually or automatically to bring the gauge at the necessary times into positions in which it can be filled from a hopper W or discharged into the container H.

Class 142(ii) The jaws of a gripper shuttle are operated by the movement of a slidable weight which is housed within the shuttle and which moves under its own inertia when the shuttle is brought to rest. A shuttle A has gripper jaws B<SP>1</SP> at each end operated by a sliding weight D Resilient converging ends D<SP>1</SP> of the weight open the members B<SP>4</SP> to close the jaws B'. Springs E press the members B<SP>4</SP> together to open the jaws B<SP>1</SP> A weft presenter which cooperates with the shuttle comprises jaws G and a spring-loaded weft guide tube L. The jaws are shrouded by spring strips J<SP>1</SP>. In operation, the picker K slides over the weft presenter and moves back withdrawal plates L', L<SP>2</SP>, against the spring L', and the weft C, held by the jaws G, projects through the face of the picker. The shuttle comes to rest against the face of the picker and the jaws B<SP>1</SP> close on the weft by the continued movement of the weight D. Inclined faces B<SP>2</SP> on the jaws B' open the jaws G when the shuttle is again picked and the tapered end L<SP>4</SP> of the tube L maintains the jaws G open. A cover plate on the top of the shuttle and the weight D are provided with a slot through which a tool may be inserted to manipulate the weight for the initial threading of the mechanism. The gripper jaws may be lined with cushioning material. The weft is held and cut at each side of the warp after insertion and the excess weft at the supply side is withdrawn so that the end of the weft is held in the jaws G. A number of weft presenters, each' carrying a weft of different colour, may be provided and may be positioned by suitable selecting mechanism.

Filed: 1926-04-26
Abstract: 274,581. Drummond, A. A. April 26, 1926. Phenol-aldehyde condensation products.-Synthetic resins of the phenol-aldehyde type are purified by treatment with the vapour of an organic solvent of lower boiling-point than water, preferably one with which the resin is miscible. The solution generally remaining after the treatment may be used directly for impregnating fillers, or the resin may be isolated by removing the solvent, for example by vacuum distillation.

Title: Electric analogue wristwatch
IPC: G04C3/00
Filed: 1977-03-15
Abstract: Mould for producing the injection-moulded plastic part, consisting of a housing upper part or steady rest and mould holder (10''). It consists essentially of an upper (100) and a lower (102) mould half, and forms between them a mould cavity for the injection-moulded plastic part (10''). The two mould halves each have a central part and an outer annular part (104, 106 and 108, 110, respectively), so that in the event of an alteration to the appearance of the dial of the watch only the upper central part (104) need be replaced, while all the remaining parts of the injection mould can stay the same. Likewise, in the event of a change in the design of the steady rest only the upper outer annular part (106) need be exchanged. Ejector pins (112) of the mould and a core (114) for mounting a set-hands arbor are provided. Upon opening of the injection mould, the core (114) is drawn outwards by a mandrel (116) mounted on the upper mould half (100), since it is guided in the lower mould half (102) to be capable of displacement in the longitudinal direction. No discharge opening of the injection mould is represented. <IMAGE>
