Title: Molding plastics spacers for wipers
IPC: B60S1/38
Filed: 1979-09-25
Abstract: The invention relates to wiper blades which comprise a harness supporting a wiper strip, the harness being constituted by a primary yoke and at least one auxiliary yoke connected at a point intermediate its length to an end of the primary yoke, a plastics spacer being interposed between the two yokes to prevent contact between the yokes while allowing limited relative pivotal motion. The plastics spacer has a cross-section similar to those of the yokes, including a web and a pair of parallel cheeks extending therefrom, the spacer having a pair of lugs moulded in alignment with each other and extending internally of the spacer from the cheeks. The invention resides in a method of moulding a plastics spacer of this kind, using a pair of complementary mould parts moving relatively to each other parallel to the cheeks of the spacer and working in opposition to each other to form the lugs between such mould parts and to form one or two openings in the web to enable one such mould part to withdraw relatively from the lugs and from the spacer through the opening or openings.

Title: Rollers for feeding ink or damping fluid in offset printing machines.
IPC: B41F31/10
Filed: 1981-01-22
Abstract: Cooled rollers (3) having a metallic circumferential surface for the transport of dyes or moistening agents in offset printing machines, in particular friction rollers. The uniform temperature distribution, extending over the entire machine width, which is required for a disturbance-free printing process is particularly jeopardised after the machine has stopped and moistening has ceased. The heat transition thus occurring from the relatively warm side walls, drive and bearing parts to the cooler roller elements leads on restarting to disturbances due to non-uniform temperature distribution. In order to prevent this heat flow, elements (12) having a low conductivity of heat are now arranged between the metallic circumferential surface of the roller (3) and the components (1, 2, 4, 5, 7, 8, 25) which heat up during machine running.

Title: Gas operated weapon
Filed: 1981-06-04
Abstract: Improvements in, or related to gas operated automatic or semi-automatic weapons. A gas operated firearm having a receiver 1 including a rear wall 100 at one end and a barrel 10 at the other, with a bolt carrier assembly 3 that moves reciprocally within the aforesaid receiver is arranged to co-operate with a main drive spring 307 that urges the bolt carrier assembly towards the barrel. The weapon is designed so that in one aspect of the invention on an automatic cocking cycle the bolt overtravels the cartridge feed point by a distance equal to or greater than the overall length of a live cartridge. In a further aspect, the gun is additionally designed using parameters calculated such that a substantially constant reaction is felt by a user. The parameters used here are essentially the product of sprung weight (the total weight in kg of all the components driven by the main spring) x the spring force (an average value of spring force that accelerates and retards the sprung weight) x cycling distance (the length of allowable travel of the bolt carrier assembly in metres) which is equal to (0.51)2 x 0.5g +-15% where I is the cartridge impulse and g is the acceleration due to gravity. The length of allowable travel of the bolt carrier assembly is arranged such that the assembly does not impact on a positive stop (100).
