Title: Improvements in machines for delivering measured quantities of materials
IPC: G01F11/28
Filed: 1936-06-19
Abstract: 480,350. Delivering measured quantities of granular and like materials. HICKS, G. A. June 19, 1936, No. 17092. [Class 106 (v)] Apparatus for delivering measured quantities of granular or like materials or for delivering Simultaneously two or more -such substances, comprises a plurality of hoppers such as 5, 6 controlled in pairs by a double valve member such as 8 reciprocable in a frame 7 by means of a cam 9 so that downward movement 'of the valves opens the hoppers to measuring chambers 12 and upward movement closes the hopper outlets and opens discharge apertures 14 of the measuring chambers. Reciprocation of the valve effects the operation of an agitator 15, 16. In order to vary the quantity of material discharged, the lower walls 13 of the chambers 12 are separately adjustable by means of members 29 and screws 31. Discharge of material from a hopper may be prevented by moving up the corresponding member 13 so as entirely to close its measuring chamber. The movement of the double valve 8 causes an oscillation of a pawl 23 driving a ratchet 24, to the spindle of which is fixed a pointer 26 which may be initially set in relation to a graduated dial 27 and a fixed stop 28 so that only a predetermined number of measured quantities may be dispensed with one setting of the apparatus.

Title: Improvements in or relating to fire alarm devices
IPC: G08B17/06
Filed: 1926-07-09
Abstract: 270,123. McCandlish, W. H. July 9, 1926. Alarms operated by fusible devices; electric alarm circuits. -A fire alarm device, preferably a modified push switch of an ordinary electric-bell circuit, is adapted for manual operation and also for automatic operation by an independent spring when a fusible member melts. In the hanging switch shown in Fig. 1, a casing j has a head k carrying electric contacts l<1>. A movable contact b is carried by a stem a guided in a frame c<1>. On the stem a are a collar b and a disc e held apart by a spring d. The stem and parts carried by it can be pushed inwardly against a spring h to close the circuit bv means of an open frame e<3>. When a fusible collar f on the stem melts, the latter, without the disc e, is moved inwardly to close the circuit, by the spring d. The contact b is mounted for oscillation on the stem a to ensure contact with all the points l<1>. The open frame e<3> permits ready access of heat to the sleeve f, and also replacement of the sleeve by removing a nut g. The casing j may have flanges for attachment to a ceiling. In a modification, Fig. 4, for attachment to a wall, a base part j<5> carries contact points l<1> and a cap j<6> carries a plate spring n against the pressure of which a contact b can be forced inwardly by hand. Fusion of a sleeve f again permits the stem a to be moved inwardly by the spring d. In a modification of this form, the spring n is carried by the base part and is connected to one of the electric leads l<2>, the other lead being connected to a single contact l<1>. In this case, the circuit is closed through the spring n, stem a and contacts b, l<1>. The thermal device described is preferably embodied in an ordinarv call-bell circuit in combination with an external circuit and bell controlled by a switch which is closed, for example at night, when the street door is closed.

Title: Improvements relating to casement and like stays and fasteners
IPC: E05C17/18
Filed: 1926-07-09
Abstract: 271,280. Tipper, A. D., and Taylor, F., (trading as Tipper, A.). July 9, 1926. Stays. - A stay that also serves as a fastener for a casement window or a door is pivotally secured to the bracket a on the window by a double hinge of which the pivot pin e is vertical, so that when the window is closed and the staybar hangs down over the projection secured to the window frame h the stay-bar is rotatable about its vertical axis on the pivot pin e. This movement brings the edge of the stay-bar into contact with the fixed projections j and the window is secured in the closed position. The outer face of the projection j may be tapered so that the stay-bar affects a tightening action in its pendant position. The lower end of the bar g may engage a fixed projection l of quadrant shape. The window or door is adjustably secured in the open position by the engagement of one of a series of holes in the bar with the upturned end k of the projection j.

Title: Improvements in and relating to the treatment of polymers
Inventor: TELFER ROBERT GILMOUR JAMIESON
IPC: C08F10/00
Filed: 1957-05-31
Abstract: Solid polymers of unsaturated hydrocarbons containing metal-containing catalyst residues are treated to remove the residues with an organoaluminium halide or a boron halide soluble in a hydrocarbon, in the presence of a hydrocarbon in the liquid phase, then with an alcohol having one to eight carbon atoms in the molecule, and the solid polymer recovered.  The treatment with the alcohol may be effected either in the presence or absence of the hydrocarbon.  The polymer may finally be treated with steam. The organoaluminium halide may be an aluminium dialkyl halide, an aluminium alkyl dihalide, or an aluminium alkyl sesquihalide.  The boron halide may be boron trifluoride etherate.  The catalyst residues are preferably those obtained by reacting a titanium compound, e.g. titanium trichloride with an organo-compound of aluminium.  Specified polymers are polyethylene, and polypropylene.

[Class 135.] Lift valves ; leakage, preventing.-In a lift stop-valve for domestic use having detachable upper and lower head portions, such as 23, 25, with an interposed ball bearing 26, the head parts are secured together by a central screw stud 31 having a shoulder which clamps the upper head part 23 to the spindle 17. This arrangement provides for relative rotation of the lower part so that when the washer 27 therein contacts the valve seating, in closing, it does not rotate in contact with the seating. The screw spindle 17 operates in a removable nut 14 provided with a feather 16 engaging a groove in the casing. Alternatively, the spindle may screw directly into threads formed in the casing body. The rubber &c. spindle packing 21 rests on a fibre washer 35 and a metal washer 22 and is covered by a soft metal thimble 34 and compressed by a screw-on cover 20. The central opening of the thimble 34 can be small enough for the smallest spindle used but is adaptable for the largest spindle size since the spindle can be readily forced through the opening of the soft metal.

Abstract: 256,385. Smith, T. B. July 13, 1925. Agitating appliances.-Apparatus for drying and neutralizing acid salts such as crude ammonium sulphate in which the salt is simultaneously heated and agitated with a neutralising agent is provided with one or more sets of stirring blades disposed radially from a main operating shaft and also with means whereby each set of blades may be independently moved into and out of normal operative position. In the apparatus shown in Fig. 1 the pan 2 into which the salt is introduced is heated by steam or other fluid and the salt is agitated by the blades 20 which are rotatably mounted on arms 18, 19 carried by operating shaft 4 which is driven by any source of power through the intermediary of pulley 9, shaft 6 and gear-box 5. The blades 20 are operated automatically by trip mechanism or manually by means of counterbalanced levers 25, near the periphery of the pan. When the levers rest against stop-members 26, Fig. 2, the blades are lifted out of their operative positions, and when both sets are operating one set tends to move the salt from the periphery to the centre and the other set tends to move it in the opposite direction so that continuous agitation is secured. To remove the salt an orifice in the bottom of the pan near its periphery is provided and by raising the appropriate set of Hades the salt is automatically conveyed through it.
