Title: Self starting vertical axis turbine with helically twisted blades and discontinuity in a blade surface
Inventor: ROBERTS MICHAEL
IPC: F03D3/06
Filed: 2009-06-01
Abstract: A self starting vertical axis wind or water turbine has helically twisted blades and an aerofoil section with a blade shape consisting of curved upper and lower surfaces and one or more voids or protrusions in the upper and/or lower surfaces to disrupt air flow. There may be a concave discontinuity on a surface of the aerofoil which may also contain bars to separate the groove into smaller voids. There may be fences or blocking partitions running in the chord direction in the groove to prevent flow along the grooves. The voids may extend from 40 percent to 90 percent of blade length and aid self starting as the voids increase drag on the blade when in the coasting or non lift generating part of the cycle. Combines the benefits of the Savonius wind turbine with that of the Darrieus wind turbine.

Abstract: Polymers are obtained by polymerizing esters of acrylic or methacrylic acid and 4-methyloldioxolane or derivatives thereof which have one or two alkyl and/or aryl substituents in the 2-position. Copolymers may also be prepared with other polymerizable ethenoid substances such as other acrylic or methacrylic acid esters or acrylonitrile.  Specified 4-methylol dioxolane derivatives are 2 : 2-dimethyl- and 2-phenylmethylol dioxolane.  Polymerization may be effected in mass, in solution in water or benzene, in dispersion, or in the presence of a preformed polymer.  It may be activated by heat, light, preferably in the presence of a photo-sensitizer such as benzoin, or by catalysts such as benzoyl and hydrogen peroxides and a ,a 1-azo-bis-(isobutyronitrile).  Preferred catalysts in emulsion polymerization are per-acids or salts, e.g. ammonium persulphate, in the presence or absence of reducing agents such as sodium metabisulphite.  Dispersing agents such as cetyl pyridinium bromide, sodium cetyl sulphate and condensation products of ethylene oxide and an octylated mixture of cresols, may be used. The polymers are generally glassy or white solids, the homopolymers being soluble in acetone and insoluble in water, the copolymer with acrylonitrile being soluble in dimethyl formamide. The preparation of the monomeric esters is described in Specification 690,709, [Group IV (b)].

Title: Improvement in and relating to liquid dispensing apparatus of the extensible hose type
IPC: B67D7/40
Filed: 1947-04-13
Abstract: 649,152. Storing hose. GILBERT & BARKER MANUFACTURING CO. April 13, 1948, Nos. 10218 and 10219. Convention dates, May 15, 1947 and Nov. 1, 1947. [Class 99(ii)] [Also in Group XVIII] A dispensing pump of the kind having an extensible and retractable hose, a motor operated pump mechanism in a housing, a hose discharge nozzle, a nozzle support, a motor switch and an interlock to require the switch being turned off when the nozzle is put on its support, a tensioning device to retain a portion of the hose within the housing for storage and to draw it back after it is pulled out, said hose having the remaining portion hung in a loop outside the housing long enough for normal use without disturbing the inside portion, is characterized by a latch which is automatically operable to latch the tensioning device to avoid its drawing back the portion of the hose normally located within the housing when such is pulled out for use. The hose 14 hangs downwards from the supply pipe into a storage well, formed between one of the side panels of the pump housing and a partition plate, and passes round a sheave 28 and then upwards out of the top of the well and, guided by rollers, across the top of the housing, under a cap 21, and emerges on the far side as viewed in Fig. 2, where it hangs in a loop. The sheave 28 by its weight acts as a tensioning device for normally holding part of the hose within the housing, for yielding to a pull on the hose to enable its length outside the housing to be increased, and for retracting the hose when the pull is relaxed. Resilient bumpers 33<SP>1</SP>, 33 are placed at the top and bottom limits of the sheave travel. To latch the sheave in a number of positions to prevent it from drawing back the pulled-out hose, it is fixed, by a stud which extends from its axle, to a slide 34 movable in a vertical slideway 35, and the slide has a latch block 37. A shoulder 40 is formed on the latch block and merges via a cam 48 to a straight portion 47 and another straight portion 49 extends below the shoulder and is offset to the right with respect to the portion 47 as viewed in Fig. 7. A number of latching members 41, as many as correspond to the number of latching positions of the sheave, are pivoted on the back of the slideway 35 and consist each of three arms 39, 43, 44, the two latter being engageable by a leaf spring 45. The interaction of the latch block and latching members leads the hose in a desired latching position but allows it to be pulled out further or retracted by the weight of the sheave. This appraises the operator of the positions in which he can latch the hose, it may have coloured bands. Specification 623,877, [Group XVIII], is referred to. The Specification as open to inspection under Sect. 91 comprises an alternative latching means in which the slide has a series of recesses which are engageable by bell crank levers. This subject-matter does not appear in the Specification as accepted.
