Title: Transmission box with two output shafts - has clutch and ratchet to allow rotation of one output shaft in one direction
IPC: F16H1/22
Filed: 1974-11-20
Abstract: This transmission box provides two output drive shafts of different speeds. If the sense of the input shaft is reversed, the sense of one of the output shafts may be reversed or the drive disconnected by operating a clutch. An input shaft is in constant mesh via a layshaft and gears with one output shaft. Another gear is mounted on a flanged sleeve which may rotate freely on the output shaft and is in mesh with a pinion on the input shaft. This pinion is free to rotate in one direction only, by virtue of an internally fitted ratchet and also has one face machined to form half of a dog clutch. The other half of the dog clutch slides axially on the input shaft under external control. When the clutch is engaged, the pinion is locked to the input shaft and the output flange thus rotates according to the direction of rotation of the input. When the clutch is disengaged, the ratchet ensures that the flange can only be driven in one direction.

IPC: B29C70/50
Filed: 1975-05-30
Abstract: In process for making continuous profiles of reinforced resin with an intrinsic curvature suitable for laying the profile helically about a cylindrical body dia. D. Continuous, resin impregnated filaments or wires are led onto a rotating mandrel having a helical surface channel corresponding in section to the cross-section of the required profile. The mandrel leads the wound-on profile through or past equipment for curing the matrix resin. the root dia. d of the channels in the mandrel are dependent on the length L of profile required to complete on turn of the profile around the body of dia. D, by the relationship 0.095 L2/D d 0.105 L2/D. Used esp. for making curved profiles from high tensile filaments of e.g. stainless steel, glass or carbon fibre bound by e.g. epoxy or polyester resin. Unlike press moulding, the rotating mandrel technique allows bonded filament profiles to be made to unlimited lengths. Profiles of different curvature are readily produced by using interchangeable mandrels or travelling strips. The natural curvature of the profile is matched to the form to be wrapped, to avoid persistent strain and stress when mounted.

Title: Intermediate pot printing system - for high speed printers is controlled by pulses which form digital parameters
IPC: B41J2/505
Filed: 1976-07-20
Abstract: A system is used for intermediate dot printing for dot printers working at high speed, as used in computer applications. The machine is designed to avoid print degradation caused by inaccurate point positioning when the print speed varies. Intermediate points are printed between normal data points, on the paper (6) so as to produce a visually better output record when the normal point spacing is large. The dot printing is controlled by pulses operating the print times. The period between two successive normal point pulses forms a first digital parameter, and another is formed as a power of half the first using a shift register. The intermediate point pulse between two normal point pulses is derived from the second parameter of the first normal point.
