IPC: F42B7/08
Filed: 1985-03-27
Abstract: A shotgun cartridge comprising a case 100 having a cylindrical wall 101 and a base 102 holding a percussion ignition means 103, the cartridge including an end closure 104 and an obturating means 105 having an upper face defining with the end closure a shot chamber containing shot 107, and having a lower face defining with the base a space containing propellant 109 in communication with the ignition means, characterised in that the end closure is of fixed position and defines a fixed volume and the obturating means includes a first wad member having an upper face bounding the shot chamber and which is located at a fixed position within the cartridge case so that its lower face determines a combustion chamber of predetermined volume, the position of the shot being fixed between the upper face of the obturating means (including any spacer member) and the end closure. A second wad 108 determines the ignition pressure of the propellant and is movable by the combustion gases to expand the lip 114 of the first wad into sealing contact with the case. Alternatively, the second wad is a bursting diaphragm (408, Fig. 4) or a stretchable membrane (508, Fig. 5) that stretches under the action of the combustion gases and bursts after moving the first wad. <IMAGE>

Title: Pharmaceutical composition in sustained release unit dose form and process for its preparation
Inventor: HARRISON PAUL JONATHAN
IPC: A61K31/44
Filed: 1985-05-30
Abstract: A pharmaceutical composition of a medicament, such as a 5-(pyridinyl)-2(1H) pyridone, in sustained release unit dosage form for oral administration is in the form of beads within a capsule of gelatin or the like. Each bead comprises an inert particulate core having adhered thereto a coating of particles of the medicament.

Title: Control for a hydrostatic piston motor
Inventor: BEYER RUDOLF
IPC: F04B1/00
Filed: 1985-11-04
Abstract: In a hydrostatic radial piston motor, the conventional mechanical control of the supply and exhaust of working fluid to the cylinders is replaced by electromagnetic changeover valves which are actuated, in dependence upon the position of the motor shaft 2, by a microprocessor 22. An angle detector 20 cooperating with a toothed ring 19 secured to the motor shaft 2 detects the position thereof. This arrangement allows the energization and de-energization of the valves 14 to be programmed as required in dependence upon the angle of motor shaft rotation. This programmable feature enables the motor to have any required acceleration curve and deceleration curve. <IMAGE>

Title: Positive pressure demand valves
Inventor: ALEXANDER PAUL
IPC: A62B9/02
Filed: 1986-07-29
Abstract: The particular problems of embedding and wear which are encountered in the positive pressure demand valves for controlling the flow of gas in a breathing system are overcome by the provision of a positive pressure demand valve which has apertured jewels (14, 15) constituting the contacting valve surfaces of both the valve seat (13) and the head (12) of the tilt valve member. Both jewels (14, 15) are resiliently mounted as inserts, the jewel (15) of the tilt head member being a snap fit in a cap (16) of a plastics and therefore resilient material, while the seat jewel (14) is cushioned by a layer (11) of resilient material in a recess in a metallic valve seat (13). The seat jewel (14) is of frusto-conical shape thus restricting the area of the contacting valve surfaces. An excellent gas-tight seal is obtained and little or no embedding or wear is experienced in use. <IMAGE>

Title: Machine and method for packing fibrous matter
Inventor: MUDGE GEORGE EDWARD
IPC: B65B63/02
Filed: 1986-08-12
Abstract: A machine for and a method of packing fibrous material, typically wool, for protection, storage and transportation within a packing sheet typically of plastics material. The machine comprises a spindle 18 mounted off-set from a work surface 10. The spindle has mounted on it a pair of drive members 30,31 each of handed helical form which during the packing operation rotate in a sense to screw the helix into engagement with packing sheet upon them and enable the drive member to be withdrawn from engagement with sheet material by an unscrewing action. Sheet material on the work surface has fibrous material for packing deposited on it. The form and location of the drive members provides for the longitudinal centering on the spindle of one end of the packing sheet. Rotation of the spindle and drive members causes the packing sheet and material on it to be drawn onto and around the spindle to provide a packed spiral of fibrous material within the packing sheet. <IMAGE>
Patent GB-2199978-A (GB)
Title: Coin validators
Inventor: FAIRHURST DAVID JOHN
IPC: G07D5/00
Filed: 1987-01-16
Abstract: A method of manufacturing a validator comprises generating data which represents the response characteristics of the validator, for example by inserting coins into the validator and using the signals generated by the sensing circuitry. The characterising data and additional data representative of the properties of coins of a particular denomination are both used to generate acceptance data which is subsequently used by the validator in testing coins to determine whether the coins are of that denomination. The coins inserted during the manufacturing operation for generating the characterising data may be of different types from those which the validator is intended to find acceptable. A validator can be re-programmed by extracting from it either acceptance data used to determine whether coins are of particular denominations, or characterising data which represents merely the response characteristics of the sensing circuitry, and combining such data in a predetermined manner with additional data representing the properties of a further coin denomination. The thus combined data is caused to be stored by the validator for future use in determining whether tested coins are of the new denomination.

Title: Turbine blade repair
Inventor: FRASER MICHAEL JAMES
IPC: F01D5/28
Filed: 1989-01-24
Abstract: A method of manufacturing or repairing a turbine blade comprises the steps of insertion of an insert into the leading edge portion of the blade situate particularly adjacent the radially outer end of the turbine blade. The insert is made of a material different from the parent material of the blade and having a higher carbon content to enable a piece of material to be satisfactorily hardened by heat treatment, the heat treatment being such that the portion of the insert adjoining the blade is not significantly hardened thereby minimising or eliminating the likelihood of the formation of cracks in the insert during use of the turbine to which the blade is secured.

Title: Brightness signal/color signal separating filter
Inventor: GAI TOSHIHIRO
IPC: H03H15/00
Filed: 1990-12-07
Abstract: A filter for separating brightness signal and color signal from a composite color signal of NTSC type of PAL type, comprising a horizontal color signal extracting filter, a vertical color signal extracting filter, a horizontal/vertical color signal extracting filter, a switching circuit, and an image correlation judging circuit. The image correlation judging circuit makes the switching circuit select: the color signal extracted by the horizontal color signal extracting filter when the horizontal correlation is judged to be stronger than the sampling value at the target sampling point; the color signal extracted by the vertical color signal extracting filter when the vertical correlation is judged to be stronger than the same; and the color signal extracted by the horizontal/vertical color signal extracting filter when neither of them is judged to be stronger than the same. The result is that mutual leakage of the brightness signal and the color signal at the area of intensive change into the another's channel can be reduced, thereby avoiding dot jamming and deterioration of image quality. The image correlation judging circuit judges the strength of correlation based on the non-correlative energy. <IMAGE>
