Title: Electric brake system for accelerated charged particle beam - has three electrodes, one consisting of pointed elements with points directed to beam from two sides
IPC: H01J3/00
Filed: 1976-09-21
Abstract: The electric braking system for accelerated charged particle beam is intended for application in high voltage tubes with electron recovery. It has three electrodes mounted behind each other in the path of the beam. The first electrode is of the same potential as the particle beam energy, the second electrode is at a potential near zero, and the third electrode is at lower potential of the same sign as the first electrode, serving as a particle target. The second electrode (11) consists of a set of pointed elements (13), whose tips are directed to the particle beam (5) from two sides. Preferably the pointed elements are in the form of sharp edges in mutually parallel configuration. Alternately the edges may be arranged at mutually orthogonal directions, in order to form a grid structure.

Title: Shear for bars of soft metal - has hydraulic cylinders to equalise forces on each side of shear blade
IPC: B26D7/14
Filed: 1977-03-10
Abstract: The shearing machine consists of an upper part (A) with a piston (7) actuated by a press. The piston (7) exerts pressure on the hydraulic fluid (8) which acts on the large piston (9). The piston (9) acts on the moving blade (4) which has a hole through which the bar (6) is placed. The fixed blades (11) support the bar (5) on each side of the moving blade. The reaction due to the shearing force is taken by the pistons (14) and the hydraulic fluid (15) ensures that the force on each piston is the same. This hydraulic equalisation of the reaction force ensures a clean cut when shearing bars of relatively soft metal.

Title: Domestic hot water supply heat exchanger - has pipes arranged in radial lines interconnected by cups hollowed in outer plates, and uses fluid from central heating circuit
IPC: F28F9/26
Filed: 1977-05-13
Abstract: The heat exchanger consists of a bundle of straight tubes held in place by two circular plates. The tubes are arranged in radial lines. Other plates are placed outside the first plates thus covering the ends of the tubes. These outer plates are hollowed in places to make cups which correspond with the ends of the tubes establishing a link between two adjacent tubes. The hollow in the two plates are alternated so that different pairs of tubes are linked at the top and bottom and a continuous circuit along one radial line is established. There is an inlet chamber fed by an axial inlet at the top and an outlet chamber and tube at the bottom. The whole unit is enclosed in a tank with a removable cover through which the secondary circuit flows. Its modular construction makes possible the coupling of several generators to obtain the required effectiveness. It is easily taken apart to allow the tubes to be descaled or replaced.

Title: Deep drawn thermo-formed tubs with polygonal rims - to allow material to enter sidewall zone from zone adjacent rim flange during forming
IPC: B65D1/26
Filed: 1977-06-01
Abstract: Thinwall thermoformed pots, pref. with a depth/dia. ratio of >5:4, are made by gripping preheated sheet between polygonal clamps, pref. square, and then forming the centre of the clamped area to obtain a cylindrical body which can draw material from shallow unclamped areas of material linking the circular top of the tub body with the polygonal rim flange. The shape allows extra material to enter the sidewall zone from that adjacent to the flange, so that the wall thickness at the rim of the base of the pot is not significantly thinner or weaker than the centre of the base or the main body of the sidewall. Typically the intermediate wall zone is 1/10th-1/20 of the top dia. or 1/20-1/30th of the pot height.

Title: Notched circular saw blade - with demountable diamond tipped teeth bits on blade edge tongues and with bit tenons entering tongue holes to be bolt fixed
IPC: B24D5/12
Filed: 1977-07-19
Abstract: The circular saw blade has demountable diamond-tipped teeth bits (4) which are secured by an expanding sleeve (6) engaging bit tenons (5). The blade has a series of identical 'U' shaped notches cut at regular intervals in the blade edge and forming level seats for the teeth bits.

Title: Sewage aeration system - with flow acceleration and deflection of bottom layers towards revolving aerator
IPC: B01F3/04
Filed: 1977-07-25
Abstract: The Parent Patent described the aeration of fluids such as sewage by converting a side stream of the fluid into a fluid/gas mixt. by centrifugal force and returning the atomised mixt. in the basin. The fluid is pref. given a higher flow velocity as it approaches the revolving aerator and the lower layers are deflected in the direction of the aerator. The higher flow velocity counteracts the tendency of the sludge particles to become deposited. Acceleration and deflection transports them instead to the action range of the aerator where they are enriched with oxygen.

Title: Water cooled IC engine - has reduced cooling passages in cylinder and oil cooled piston
IPC: F01P3/06
Filed: 1977-11-17
Abstract: The connecting rod (11) of an internal combustion engine has passages (8, 9) in it through which oil reaches a passage (13) inside the piston. The connection between the connecting rod passage and the piston passage is made through a spring loaded sleeve (12). The oil flows from the inlet passage (13) in the piston through further internal passages (7, 14) from which it escapes to drop back into the sump. In passing through the piston it absorbs heat and cools the piston. The cylinder (15) is made with thin walls with reinforcing ribs (18). It is thickened to contain cooling water passages (17) only at the section at which combustion takes places. This avoids unnecessary cooling and the reby improves the engine efficiency as well as making it cheaper to construct.
