Inventor: EICK GEORGE HAROLD
IPC: C04B28/04
Filed: 1965-07-27
Abstract: Portland cement concrete of inhibited efflorescence is made by incorporated into, or applying on the surface of, the concrete or dispersion in water of 30-70% of pinaceae heavy ends material providing units of tall oil pitch optionally extended with up to 4 parts of asphalt), mixtures of tall oil pitch and tall oil rosin (optionally extended with up to 4 parts of asphalt), or tall oil rosin extended with up to 4 parts of asphalt, said asphalt (when present) having a penetration between 250 and 500 and a softening point between 85 DEG  and 140 DEG  F., said dispersion also containing 0.1-5 wt. per cent, based on the heavy ends, of sodium hydroxide (or an equivalent amount of another water soluble basic compound), and 0.1-15 wt. per cent, based on the heavy ends, of protective colloid.  Suitable alternative basic compounds are KOH, NH4OH, Na2CO3, sodium aluminate and triethanolamine; and suitable colloids are casein, soyabean protein, egg albumin, gum arabic, starch, gelatine, methyl cellulose, animal glue, dextrine, and sodium alginate.  The dispersion may also contain a fungicide, e.g. phenyl mercury acetate or N-(3-chloroally) hexaminium chloride.  The aggregate in the concrete may be expanded shale, expanded slag, limestone, sand, dolomite, crushed stone and/or gravel, and the term "concrete" includes masonry cement and conventional concrete mortar. The concrete may be coloured, e.g. by ferric oxide or ferrite yellow pigments, the dispersion of which through the concrete is enhanced by the heavy ends dispersion.

Abstract: 391,713. Smallarms. FROMMER, R. VON, 158, Soroksari Ut, Budapest. Nov. 14, 1932, No. 32176. [Class 119.] Relates to trigger mechanisms for smallarms of the kind in which the trigger 1, Fig. 1, fulcrums successively about two projections 6, 9, provided thereon. According to the invention, at least one projection is capable of adjustment by means of a set-screw 8. In the form shown, the trigger is pivoted at 2 to a spring-controlled pivoted sear 3, an upstanding detent on which is adapted to retain a striking element 10 in its retracted position. The projection 9 is formed integral with the screw 8 which extends through the trunk of the trigger. By turning the screw, the position of the projection 9 with respect to the trigger can be varied. In a modification, the screw extends through a rearwardly extending lug formed on the trigger. In a further modification, Fig. 3, the projection 6 is adjustable, the projection 9 being formed integral with the trigger.

Filed: 1919-12-29
Abstract: 159,080. McKean, J. G., and Jones, R. r. Dec. 29, 1919. Liquid-fuel furnaces.-In a liquid-fuel furnace front of the type wherein the entering air passes through annular passages formed by a plurality of conical or cylindrical members, these members are bell-mouthed at their outer extremities and the air-supply is regulable by a sliding sleeve engaging with the peripheries of the bell-mouthed members. A ring c, attached to the furnace front, supports the bell-mouthed members e, which prevent direct radiation from the furnace and consequently heat the incoming air. A centrally-disposed fuel-atomizer l projects through a perforated closing-plate k and supports a primary air-supply regulating-valve m, the longitudinally movable sleeve h controlling the secondary air supply. The furnace front is lined with firebricks n which are, however, dispensed with in the modification shown in Fig. 3, in which case the secondary air is regulated by a conical member h<1> which slides over the extension j, the air being admitted between the furnace-front and the cylindrical rim of the member h<1>. The air is heated by contact with the furnace front and a conical deflector o may be provided. The ring c may be secured to or hinged to the furnace front.

Abstract: 1,151,290. Injection moulding machines. PENNSALT CHEMICALS CORP. 14 July, 1967 [25 July, 1966], No. 32602/67. Heading B5A. In an injection moulding machine having a reciprocable screw 40, the screw is rotated in the reverse direction after the injection stroke while still being urged towards the mould 16a, 16b. Any material obstructing the injection passage is thereby cleared whereby the machine may be used for injecting thermosetting materials. The injection cylinder 32 and screw 40 are tapered at their forward ends, and the nose of the screw may carry a continuation of the screw flight 42. Alternatively, the flights on the nose of the screw may be of very small pitch (see Fig. 4, not shown), or may be of opposite hand to the flight 42. In further alternatives longitudinally extending vanes or splines may be used, or a series of projections extending out from the screw head body. Means may be provided to stop the forward motion of the screw just short of the tapered wall 36 and means to give a signal if the screw does not reach a point adjacent the tapered wall after a preset period. Limit switches or timing means can be used to commence the reverse rotation of the screw at a given position during its forward movement.

[Also in Division F4] A liquid spray nozzle, e.g. for use in the burners of gas turbine engines, is formed from a tubular body 10, Fig. 2, and an end wall 11 having (1) in its interior surface an annular groove 12 defining an island 13 through which runs a diametral bore 14, and (2) an external slot 16 extending in a direction transverse to the bore and communicating with it. Diametral grooves 17 and 18, Fig. 4, are formed in the nozzle head, as shown. The nozzle is mounted on a supporting stem 19, Fig. 5, enclosed within a sleeve 20. The sleeve has an inlet 22 for pressurized air, which flows through the annular space and the grooves 18 (only) in the head :of the nozzle, and a diametral slot 24 aligned with the slot 16 of the nozzle: When pressurized liquid and air are supplied to the stem 19 and inlet 22, respectively, the issuing fan-shaped air flow envelops and assists in the atomisation of the similarly orientated flat fanshaped spray of liquid.

Abstract: 914,374. Drum-lifters. GOODBOURNE & BYRNE Ltd. Aug. 17, 1961 [Sept. 23, 1960], No. 32802/60. Class 78 (4). A drum-lifter of the type described in Specification 893,998 is modified by having the head 25 carrying jaws 36, 38, supported from an intermediate frame 60 by means of depending links 21, 22, the frame 60 being pivoted to the main frame 13 at 64 so that it rests against a stop 68 when the jaws are not urged against a drum. When the head is pushed against a drum the frame 60 is rocked back against the frame 13 and the head swings down on links 21, 22 against the action of a biasing spring 29. Initially the jaw 36 rises and engages under the rim of the drum causing the upper jaw to descend and grip the rim before the resistance of the spring 29 is felt. Thus there is no tendency for the drum to be knocked over. Pins 67 permit vertical adjustment of the head on the frame 13.

In a method and apparatus for indirectly heating granular material, the material drops freely through thin flat vertical chambers 1 from a container 7 through control devices 8, the chambers having at least one dimension of its cross-section from a few to about forty millimetres. The chambers are surrounded by heating flues 2, the heat being supplied by gas burners 3 and the gas entering through a duet 4 and combustion air through peepholes 5. Electric or water heaters may alternatively be used. Heat is transmitted to the material through the chamber walls and the waste gases are removed through channels 6.
