Abstract: 1,182,331. Filling machine. J. F. TERRETT, F. J. HODGES and C. H. HIGNELL. 18 March, 1968 [16 March, 1967], No. 12422/67. Heading B8C. [Also in Division Al]. The lowermost open-top container of a stack 12 in a magazine 10, is moved below an adjacent hopper 14, for granular material, by a pusher 18 which is drawn clear of the stack to allow the next container to fall into position. Each empty container pushed below the hopper 14 moves a filled continer past a levelling roller 39 and under a tamping plate 28. The plate may be spiked &c. to indent the surface and a roller 32 surfaces the compacted material. A handle shaft 27 may be used to reverse the pusher to unblock the machine in the event of a jam. A spring operated microswitch may stop the machine if the magazine needs replenishing. Machine parts which contact the material may be coated with non- stick material. The containers may be divided to hold e.g. flower pots.

Title: Improvements in locks
IPC: E05B35/08
Filed: 1924-05-21
Abstract: 238,612. Hamburg, D. May 21, 1924. Lock-mechanism, change-key; slider-type; padlocks; keys.-A lock with a permutable key is provided with two-part sliding tumblers, one part having the key-engaging notch and the other having the notch co-operating with the bolt-stump or like part, the parts of the tumblers being relatively adjustable for changing the necessary arrangement of the key-bits. The lower part 6 of each slide has a notch 8 for engaging the key and a pair of notches 9, 10 into either of which fits a lug 12 in the upper part 11 which has a notch 15 for engaging the bevelled lug 16 on the bolt-controlling member 2. This member is normally pulled inwards to retract the bolt 1 by a spring 3 which also actuates a bell-crank lever 4, 5 to press all the sliders to the left. The key comprises a stem 17 screwing into a member 18 carrying a squared part 19 on which fit the bits 20. These bits are arranged on the stem 17 in a given order, some pointing to the left and others to the right, and are then pushed up to the squared part 19 and clamped up by the nut 21. The key is then put into the keyhole and the parts 11 of the sliders lifted out of engagement with the parts 6 by a hand-lifted plate 13. The key is then turned to the right so that the bits on one side of the key slide the corresponding parts 6 to the right while the bits on the other side hold the other parts 6 stationary. The plate 13 is then lowered so that the projections 12 engage the notches 9 of those parts 6 which have been slid to the right and the notches 10 of the other parts. The key is then turned back moving the first-mentioned parts 6 back to the left so that all the parts 6 are in the position shown in Fig. 1, while some of the parts 11 have moved further to the left, lifting the projection 16 and shooting and locking the bolt 1. Release can only be effected by the key arranged to move the correct sliders to bring all the notches 15 under the projection 16. Fig. 6 shows the invention applied to a padlock, a horn 22 in the pivoted member 2 engaging the shackle-end. The key-bits and sliders are of uniform size, the manner in which they are arranged relatively giving the lock its security.

Abstract: 564,679. Alloys. MOND NICKEL CO., Ltd. Aug. 7, 1943, No. 12788. Convention date, Aug. 7, 1942. Drawings to Specification. [Class 82 (i)] Gray iron castings'having improved resistance to growth are made from nickel-chromium cast iron in which the ranges of the respective elements are adjusted, particularly having regard to the cross-sectional thickness of the casting, and silicon is added to the melt just before pouring in order to increase the proportion of graphitic carbon and so prevent the iron from being white or mottled, and so unmachinable, brittle, and susceptible to cracking when suddenly heated or cooled. The iron contains 2.9-3.3 per cent carbon, 1.5-4 per cent nickel, 0.9-1.3 per cent chromium and 1.35-2.1 per cent silicon. The amount of silicon added shortly before casting may be 0.25-1 per cent, but is preferably 0.5-0.75 per cent by weight of the molten metal. The nickel content preferably does not exceed 2 per cent. The metal may include 1 per cent, but preferably 0.6-0.9 per cent, manganese. Sulphur not exceeding 0.15 per cent may be present, and also phosphorus, normally below 0.25 per cent, but for certain purposes, e.g. some cast stove plates, from 0.6-1.0 phosphorus may be advantageous. The iron is particularly applicable to fire-box parts, such as those used in sintering machines, and may also be used for furnace pots, furnace ring sections, gas-producer ring sections, grates and grate bars, exhaust manifolds, piston rings of Diesel engines, and cylinder liners.

Title: Improvements in coagulating rubber from latex
IPC: C08C1/14
Filed: 1947-05-13
Abstract: Rubber latex and the latex from plants such as Sonchus Oleraceus are coagulated by passing an alternating current through the latex and thereafter superimposing a direct current upon the alternating current, the electrodes used being such that they cause no rectifying action on the alternating current.  Preferably the alternating current is passed till complete or nearly complete creaming occurs whereupon the direct current is superimposed and the alternating current reduced to approximately one-third or half of its original value.  Soon after the direct current is applied rubber separates from the residual serum and collects in the upper part of the solution in a solid mass which may be removed and sheeted.  The electrodes may be of stainless steel or of carbon. The process should be conducted at a temperature not greater than 65 DEG  C. and preferably below 45 DEG  C.
