Title: Apparatus for discharging granular material
IPC: B65G65/48
Filed: 1975-04-28
Abstract: 1501667 Discharging hoppers F J MIKSITZ and A L MIKSITS 28 April 1975 [6 May 1974] 17524/75 Heading B8S Granular material is discharged from a bin or hopper which comprises a side wall 12 and a bottom horizontal shelf 14 having a material discharge aperture 16, by means of a circular feed plate 22 disposed in a horizontal plane below a shroud 18 for movement in an orbital path such that a portion of the periphery of the plate 22 extends beyond the bottom of the shroud 18 during motion thereof, and a feed aperture 36 in the plate 22 causes material to be discharged through the discharge aperture 16, the latter being smaller than the feed aperture 36 so that a portion of the upper surface of the shelf 14 is exposed within the feed aperture 36. The plate 22 is driven by means of an electric motor 26 whose drive shaft 28 is connected by a crank arm 30 to a stub shaft 32 located in a bearing 34 connected by legs 38 to the plate 22. Rotation of the latter about its own axis is prevented by the disposition of shroud support legs 20 in notches 24 in the plate periphery. In the embodiment of Fig. 4 (not shown), the plate (22) is of smaller diameter than that of the bottom of the shroud (18) so that the plate (22) can rotate about its own axis during orbital movement thereof. Fig. 5 (not shown) discloses apparatus in which the plate (22) is in two parts, an outer annular part (22a) and a concentric lower inner annular part (22b), the shelf (14) being of step form with the annular parts (22a, 22b) associated respectively with the upper and lower parts of the shelf (14). Both the plate parts are rotated simultaneously by means of common legs (38) connected to the motor, the plate parts being capable of both orbital and axial rotation, as in Fig. 4. The embodiment of Fig. 6 (not shown) is similar to that of Fig. 5, except that the plate parts are prevented from axial rotation, as in Fig. 1. The bin or hopper may be provided with aeration nozzles or jets to inject air or gas into the mass of material, or else the bin may be vibrated.

Title: Thiophosphoric acid esters
IPC: C07F9/165
Filed: 1958-06-02
Abstract: The invention comprises thiophosphoric acid esters of the formula <FORM:0835186/IV (b)/1> wherein R1 is C1-C4 alkyl, R is C1-C4 alkyl which may be unsubstituted or substituted and X is O or S.  The substituents in the group R may be alkylmercapto, alkoxy, or cyano groups or halogen atoms.  The products may be obtained by reacting an a -halogeno-b -trichloroethyl alkyl ether of the formula Cl3CCH(Hal) (OR) in which Hal is halogen and R is as defined above with an appropriate O,O-dialkylthiol - (or thionothiol) - phosphoric acid. The latter may advantageously be used in the form of their ammonium or alkali metal salts and the reaction may be effected in a suitable solvent e.g. an alcohol, ketone, or hydrocarbon at 50-120 DEG  C. The a -halogeno-b -trichlorethyl alkyl ether may be obtained by adding chloral to an alcohol (ROH) to form a semiacetal of the formula Cl3C.CH(OH)(R) and then replacing the hydroxy group by a halogen atom, e.g. by means of phosphorus pentachloride, thus the compound Cl3C.CH(Cl) (OCH2CH2SC2H5) which is used as starting material in one of the examples given may be obtained by condensing chloral with b -ethyl-mercapto ethanol and chlorinating the resulting semi-acetal with phosphorus pentachloride.  The thiophosphoric acid ester products have good insecticidal properties (see Group VI).ALSO:An insecticidal composition comprises a solid or liquid carrier or diluent and one or more thiophosphoric acid esters of the general formula <FORM:0835186/VI/1> wherein each R1 is a C1-C4 alkyl radical, R is a C1-C4 alkyl radical which may be unsubstituted or substituted, e.g. by an alkylmercapto, alkoxy or cyano group or halogen atom, and X is oxygen or sulphur (see Group IV (b)). Specified carriers or diluents are talc, chalk, bentonite, clay, water-if necessary with a commercial emulsifier, e.g. a benzyl hydroxy diphenyl polyglycol ether containing 10 to 15 glycol residues, alcohols, ketones, hydrocarbons and dimethyl formamide which is mentioned as an auxiliary solvent.  Known insecticides and/or fertilizers may also be present.

Filed: 1948-06-30
Abstract: 655,498. Moulding rubber soled footwear. VANAKER, J. June 30, 1948, No. 17647. [Class 87 (ii)] A mould for moulding footwear bottoms containing a sponging agent to lasted uppers comprises a base 1 and an upper frame 2 with an intervening gap 15 extending round a major part (e.g. the sole part) of the mould perimeter and designed to permit controlled escape of sponging, gases generated during the vulcanizing. The upper frame has a depending ridge 12 mating with a corresponding groove 10 in the base to form a shallow V-shaped gap introducing a change of direction in the motion of the outflowing gases. The mould parts have a rolling surface contact at the two ends of the mould where they are located with respect to each other by pins and sockets. The rolling contact permits relative adjustment of the gap at the two sides of the mould. The mould parts may be rough aluminium castings, the sole-forming part of the base being hollowed and terminating in a ridge 19 at the junction with the groove 10. The roughness of the surfaces in the gap 15 assists in restraining the escape of gases. The heel and sole moulding surfaces are formed with scorings 18, the relief portions of which at the edge of the sole portion extend towards the upper frame and assist in breaking up the gas flow through the gap 15. The surface 21 of the upper frame (which bears against the upper), is preferably machined smooth and also the surface 22 and the under surface of the shoulder 23 on the upper frame which mould the edges of the sole. The sole material may consist of two sheets of rubber stock, one containing a sponging agent, calendered together. Dimensions of a typical mould are given.
