Title: Improvements in or relating to apparatus for distributing fertilizers and like materials
IPC: A01C17/00
Filed: 1948-02-13
Abstract: 646,305. Fertilizer distributers. CROWE, R. K., and BRAUND, S. C. E. Feb. 13, 1948, No. 4330. [Class 6(i)] .A machine for distributing fertilizer or grit of the kind comprising a hopper 25 fitted with a worm conveyer which feeds material to a discharge opening 37 where it falls on to a rotatable table 47 driven by a variable speed friction wheel 51, is characterized in that the 'worm conveyer comprises two coaxial worms 32, 33 of opposite hand, and means are provided to vary the size of the discharge opening. As shown, the wheel 51 is longitudinally adjustable on a driving shaft 52. The worm conveyer is formed from strips supported on a shaft 26 by radial bars 35 which pass through the shaft, the projecting portions 36 forming beaters to breakup lumps in the material. The worm conveyer and wheel 51 are driven by chain and sprocket gearing, each from a separate landwheel. The opening 37 is provided with an adjustable lever-operated shutter. In a modification the worm conveyer may be enclosed in an open-ended tunnel in the base of the hopper and the apparatus may be driven by the power shaft of a vehicle in which case it may be wholly supported by the towing vehicle.

Title: Improvements in or relating to the automatic control of d.c. electric circuits for the charging of storage batteries or for other purposes
IPC: H02J7/02
Filed: 1941-04-02
Abstract: 549,708. Automatic regulation; charging batteries ; electric resistances. OLDHAM & SON, Ltd., and MILLER, R. S. April 2, 1941, No. 4397. [Class 38 (iv)] [Also in Group XXXVI] The potential variations of a load circuit supplied from a source giving a voltage varying inversely with the load are compensated by a carbon pressure resistance e varied by electrothermal means. The load current may pass through a metal strip h in series with the load whereby pressure due to its expansion or flexure is operative upon a resistance such as a carbon block e lying between conducting plates, f, g, whereby it is connected in series with the circuit. Bimetallic strips anchored at their extremeties may bear through spring strips h<SP>1</SP> upon a pressure plate i insulating them from the resistance element. The resistance variation may be less or greater than that required for voltage compensation. The invention may be applied with a rectifier b for charging batteries from an A.C. source and arrangements j, k as in Specification 549,707 may be added to provide artificial loads in substitution for batteries removed from a charging frame.

Title: Concrete of improved strength
IPC: C04B24/42
Filed: 1958-02-11
Abstract: Structural concrete having unproved compressive strength comprises Portland cement and 0,05 to 1% by weight thereof of one or more siliconates of the general formula: R Si (OM)n O3-n,/2 where R is a methyl, ethyl, propyl, vinyl or allyl radical, M is an alkali metal and n is 1, 2 or 3.  Preferred siliconates include sodium monomethyl siliconate, potassium ethyl siliconate, caesium vinyl siliconate and symmetrical dipropyl tetrasodium disiloxanolate.  The concrete is prepared by admixing the siliconate with the Portland cement and using the resultant dry mix with aggregate and water; alternatively the siliconate can be added to the water used to prepare a standard concrete mix. Other additives, e.g. freezing preventitives, air entrainment agents, setting regulators, may also be incorporated in the concrete which, if desired, may be reinforced and/or prestressed. Specification 788,943 is referred to.

Title: Stain removal in colour photography
IPC: G03C7/30
Filed: 1953-02-17
Abstract: 736,881. Photographic processes. AGFA AKT.-GES. FUR PHOTOFABRIKATION. Feb. 17, 1953 [Feb. 19, 1952], No. 4442/53. Class 98 (2). Stains formed on photographic colour images by the reaction of any phenolic hydroxy groups present in the image dyestuff with heavy metals (for example iron) present in the processing solutions or wash water, are removed by treatment with an aqueous solution of a polyphosphoric acid or a complex-forming organic polycarboxylic acid or a water-soluble salt thereof. Such treatment also removes any stains of Prussian blue formed by bleaching coloured images contaminated with rust particles in a potassium ferricyanide solution. Suitable compounds, which have a greater affinity for the heavy metals than the phenolic hydroxy groups are polyphosphoric acids, tartaric, citric, diglycollic, and thiodiglycollic acids and polycarboxylic acids containing an amino group such as ethylene-bis-(imino-diacetic acid), trimethylamine-α,α<SP>1</SP>,α<SP>11</SP>-tricarboxylic acid, 1,2-diamino-4-methylcyclohexane-N, N<SP>1</SP>-tetra-acetic acid, propylene-1,2-diaminotetra-acetic acid, di-isopropylene diamino-tetraacetic acid and 1,3-diamino-propane-2-ol-tetraacetic acid. The water-soluble salts of any of these acids may be used, in particular, sodium hexametaphosphate. Specification 474,082, [Group III], is referred to.

Title: Improvements in or relating to pistons particularly for internal combustion engines
IPC: F02F3/00
Filed: 1924-02-21
Abstract: 211,878. K³chemann, W., and Wucherer, F. Feb. 23, 1923, [Convention date]. Pistons; balancing laterally. - In a piston of aluminium or magnesium alloy, an inner castiron &c. ring or rings or strut expands the piston while cold in a direction at right angles to the gudgeon - pin. Owing to the greater expansibility of the piston, the action of the inner rings &c. ceases when the piston is hot and the piston resumes a circular form. A conical ring b may be pressed or screwed into raised conical seatings c at right-angles to the gudgeon-pin axis, the ring being clear of the skirt at intermediate points. The ring b may be replaced by a strut. To assist the deformation, the skirt may be drilled, grooved or slotted and the gudgeon-pin bosses may be carried by the head and unattached to the skirt. The latter may be. separable from the head and screwed to it. In order to compensate for permanent deformation of the skirt by the ring b, the skirt may be originally of greater diameter in the axis of the gudgeon-pic and may be so formed by partially deforming the skirt and then turning circular.

E. ; Port Jefferson, Long Island, New York, U.S.A.) Feb. 18, 1936, No. 4940. Convention date, Feb. 21, 1935. [Classes 40 (iii) and 40 (v)] The frequency of short-wave oscillators, amplifiers, &c. is controlled by a resonant element 2, Fig. 1, a quarter-wavelength or an odd multiple thereof long, which element is connected or coupled at one point p in its length to the grids of a push-pull pair of valves 14, 16, or to other elements requiring to be excited in phase opposition. The resonant element 2 preferably comprises a straight copper tube axially disposed in a grounded metallic cylinder 4 and connected thereto at one end. In Fig. 1, coupling to the tube is effected inductively by a loop of wire 8 projecting into the cylinder near the end at which the tube and cylinder are connected ; and the filaments are connected by a resistance 26 grounded at its mid-point. A tuned circuit 30 is connected between the plates and is coupled to the load, modulation being effected by a transformer 36. Two separate loops each tuned by a condenser may enter the cylinder through its end G and may lie on opposite sides of the tube 2 so that they pick up voltages in opposite phase and apply them to the grids of the valves. In this case, one end of each loop is connected to the earthed cylinder 4, and the filaments are earthed, Fig. 2 (not shown). In Fig. 3, a conductive connection is made at the point p of the tube 2 and a series-tuned circuit comprising coil 70, condenser 72 and coil 74 is connected between p and earth. The grids of valves 14, 16 are connected across the condenser 72 whilst the filaments are connected to earth through condensers 88, 90. The filaments are connected by a condenser 87 and current is supplied thereto by a battery 86 through long tuned conductors 84 of adjustable length. The plate circuit comprises an inductive loop 58, tuned by a condenser 60. Alternatively, the filaments may be fed through choke coils. The circuit 70, 72, 74 may be replaced by a circuit comprising two condensers separated by an intermediate coil, which is centre-tapped and connected in push-pull to the grids Fig. 4 (not shown).
