Title: Unidirectional drive assembly
Inventor: HARDY WILLIAM
IPC: F16H3/00
Filed: 2009-03-31
Abstract: A ratchet unidirectional drive assembly, e.g, for wave power generation, comprises a drive assembly with coaxial input and output shafts 12, 16 that are interconnected by a first freewheel 15 that couples rotation of the input shaft 12 to the output shaft 16 in a first direction. Rotation in an opposed second direction is not transmitted to the output shaft 16 through that freewheel 15. An intermediate assembly 20 is arranged parallel to the drive assembly and has first and second intermediate shafts 21, 22 interconnected by a second freewheel 24. A first drive train, e.g. a sprocket and chain mechanism 26, 27, 28, couples the rotation of the input shaft 12 to the first intermediate shaft 21 in the same direction and a second drive train 29, 30 couples the output shaft 16 to the second intermediate shaft 22, in an opposite direction. Rotation of the input shaft 12 in either the first or second direction causes rotation of the output shaft 16 only in the first direction.

IPC: G06F9/38
Filed: 2009-06-05
Abstract: A data processing apparatus 200 includes vector processing unit 206, comprising pipeline stages (104, 106, 108) and plural lanes of parallel processing, and has access to vector register data store 208, having a plurality of registers, during execution of a sequence of vector instructions. Skip indication storage (506) maintains a skip indicator for each lane. Vector processing unit 206 responds to a vector skip instruction to update skip indication storage by setting the skip indicator for a determined one or more lanes. Vector processing unit 206 responds to a vector operation instruction to perform an operation, in parallel, on data elements input to the plurality of lanes, but to exclude from the performance of the operation any lane whose associated skip indicator is set. Vector skip instructions may indentify a bit mask for lanes. Skip indicators may be skip counters or remain set until a skip end instruction is executed. Lanes may be excluded by preventing operations or discarding result values. The nesting of vector skip instructions is allowed. Skip indicators may be set by evaluating condition codes. The invention allows vector instructions to be performed conditionally within lanes without any modification to the vector instructions specifying those operations.

Title: Improvements in and relating to runner blades for pumps, blowers or compressors
IPC: F04D29/24
Filed: 1957-03-27
Abstract: 859,815. Centrifugal pumps, blowers and compressors. BOHMANN, W. March 27, 1957 [March 31, 1956], No. 10023/57. Class 110 (1). The camber line of an impeller blade for a pump, blower or compressor is curved forwardly at the entry end in relation to the form necessary for shock-free entry. This gives a point of inflection at X. The increase in relative flow velocity at the entry end due to the forward curvature prevents or reduces the formation of a turbulent zone due to the flow leaving the rear face of the blade. In the example shown, the turbulent zone is confined to the region of the trailing edge of the blade. The resultant reduction of losses more than compensates for any additional losses through departure from shock-free entry. The blade may be of laminar instead of aerofoil form. The amount of forward curvature, or the blade length over which the forward curvature occurs, may increase from the back-plate of the impeller to the coverplate.

Abstract: 333,159. Soc. of Chemical Industry in Basle, Merki, W., and Scheidegger, P. April 2, 1929. Addition to 285,856. Medicines for internal use; manufacture of medicines.-The process described in the parent Specification for treating internal secretory organs of females by cooling by admixture with an indifferent refrigerating agent, such as solid carbonic acid, pulverizing them, if desired with addition of an agent which combines with water, and extracting the powder so obtained with a suitable solvent, is applied according to the present invention to the treatment of animal or vegetable materials generally, for the production of physiologically active extracts. Treatment of internal secretory sex organs of animals and the use of liquid gases as refrigerating agents are excluded. According to examples (1) anterior lobes of hypophysis glands are mixed with solid carbon dioxide, ground, and repeatedly extracted with strong alcohol; water is added to the extract and the alcohol expelled, and the emulsion so obtained is extracted with ether to yield lipoids and an aqueous fraction which is evaporated to dryness; (2) yeast is similarly treated to obtain a lipoid fraction which deposits crystals of ergosterol, and a delequescent watersoluble portion; (3) hearts of warm blooded animals are similarly frozen and powdered, and extracted with 60 per cent alcohol; protein is separated from the solution by addition of acetic acid, and lipoids are extracted with a water-insoluble solvent to leave an active aqueous extract; (4) bone marrow similarly frozen and ground is repeatedly extracted with strong ethyl or methyl alcohol, the alcohol is expelled from the extract by vacuum distillation, if desired with simultaneous addition of water, and the residual emulsion is extracted with ether or other solvent to obtain an oil; (5) ox spleen mixed with solid carbon dioxide and powdered is extracted with aqueous acetone, and the solution, freed from acetone, is extracted with ether to leave an aqueous solution which, after precipitation of proteins by addition of acetic acid, is evaporated to obtain a physiologically active powder, (6) fresh blood frozen and powdered is covered with strong alcohol, stirred during and after thawing and filtered to obtain an extract which is further treated, as in the first example, to yield a lipoid fraction and an aqueous fraction, the former of which accelerates coagulation of the blood.

Abstract: 365,423. Racket covers. HALPIN, A., 45, East 20th Street, New York, U.S.A. April 7, 1931, No. 10277. [Class 133.] In a combined racket press and cover wherein the press frames are interconnected at the corners by compression bolts, the cover is positioned entirely between the frames and is provided with holes adjacent to the edges, for receiving two or more of the bolts, which also serve to hold the cover in a flat stretched-out position. As shown in Figs. 1 and 3, the clamping bolts 19 of the frame members 17, 18 pass through eyelets in the cover 12 which is thus secured in position between the frames. The racket may be introduced into the cover at an opening 15. Springs 23 tend to open the cover. To economize material, only the bolts at the narrow end of the press may pass through the cover which may be reduced in width at the other end. In a modification, instead of the bolts passing through the cover, spring hooks 29, Fig. 5, or eyelets 34, Fig. 6, may be secured to the edges of the cover in suitable positions to engage the bolts. In a further modification the constituent portions of the frames are broadened, or the press otherwise modified so as to make contact all round the racket frame and thus form an airtight closure for the gut.

Abstract: 480,833. Combination locks. JENSEN M. April 12, 1937, No. 10359. [Class 44] A combination lock consists of a spring- urged locking bolt 3, adjustable levers 7 capable of being moved axially so that a cam disc 6 and a cancelling disc 5 provided with teeth may enter them, and a spring 8 which will cause the discs to snap out of the levers when these have been moved by pressure on their outside arms to enter the levers and will allow the locking arm 13, due to axial tension, to pass the locking cam 12 on the bolt during locking. To unlock the bolt 3, the levers 7 are first set so that the teeth of the disc 6 may enter the holes b, pressure is then put on the outside arm of disc 6 and arm 11 enters recess 10 on the bolt ; this allows the locking arm 13 to clear cam 12 and the bolt 3 to snap back. On release of the outside arm, the arm 11 moves out of the bolt under the action of spring 8 and arm 13 moves down and causes the teeth of the cam disc to be drawn out of the levers. Cam 14 on the bolt 3 co-operating with an arm 15 on the disc 5 causes the teeth of this disc to enter the levers 7 and return them to a middle position. To close the lock, the bolt is gripped at handle 16 and brought so far down that the locking cam 12 passes underneath the arm 13. False holes c and d are made in the levers 7, to prevent unlocking by feeling.
