Title: Improvements in or relating to rolling bearings
IPC: F16C33/78
Filed: 1967-10-03
Abstract: A roller bearing comprises an outer race, an inner race and rollers mounted therebetween, the outer race having two spaced-apart radial walls and the inner race having an annular seal of deformable material mounted thereon, the seal gripping the inner race firmly but being movable axially by the application of a force and the seal having two lips which define a small clearance or no clearance with the radial walls of the outer race. In an embodiment the radial walls comprise a washer 11, Fig. 1, a flange 12 of which is secured to an outer race 3 and a flange 13 of said outer race 3. A seal 14 is fitted on to a shaft 1 which also serves as an inner race, and is provided with lips 16, 17. The seal may be temporarily deformed during assembly and may be provided with a non- circular bore to ensure a tight grip on the shaft 1. Alternatively the tight grip is provided by means of projections or cavities in the seal engaging cavities or projections in the shaft. Rollers 6 are mounted in a cage 4 which is located by means of the washer 11. In another embodiment the cage is replaced by means of an extension 19, Fig. 2, of an outer race 18 and an extension 21 of a washer 11, the extensions retaining rollers 6 in the bearing.

Title: Method of reproducing an image using a diazotype film
IPC: G03C1/52
Filed: 1968-11-27
Abstract: A photographic process comprises imagewise exposing a diazotype material having a linear latitude greater than 0.7 (linear latitude being defined as the extent of the linear portion of the H and D curve on the log E scale, the linear portion being that portion at which there is no more than a 20% deviation from the average slope of the linear portion) and developing using an alkaline gas at a pressure greater than atmospheric the diazotype material comprising a support and a layer containing a diazonium compound and two couplers with different coupling rates, the ratio C, of the molar concentration of the faster coupler to the molar concentration of the diazonium compound(s) being less than 1:1 and more than 0 2:1 and the ratio of C 1 K 1 to C 2 K 2 being at least 5:1, where K 1 and K 2 are the coupling rates of the faster and slower couplers respectively and C 2 is the ratio of the molar concentration of the slower coupler to that of the diazonium compound(s). Specified faster couplers are dihydroxynaphthalenes, pyronones and 2-hydroxy-3-naphthoic acid amides. Specified slower couplers are phenols, and resorcinol ethers. In the examples, the light-sensitive solutions are applied to a cellulose ester support with ratio C, being greater than 1:1 as the diazonium compound is more slowly imbibed than the coupler because of its greater size. Thus the dried materials have the correct ratio C, and give linear latitudes of 0À82 to 1.55 on development. The light-sensitive solution preferably contains two diazonium compounds and optionally contains benzamide or an ultraviolet absorber such as thienyl-2-vinyl thienyl sulphone. Alternatively, a cellulose ester may be added to the light-sensitive solution and the solution then coated on a polyester support the ratio C, for this solution being within the specified limits.

Title: Electrical connectors for printed circuit boards
IPC: H01R12/72
Filed: 1969-01-18
Abstract: An electrical edge-connector comprises a channel-shaped insulating housing containing a plurality of contact elements, each of which has portions extending through respective openings in the housing side walls and engaging the side wall, so that the side walls are supported by the contact elements and the contact elements are located in the housing by the side walls. In a preferred embodiment, (Figs. 1, 2), each element comprises two contact arms 8 formed integrally with lugs 10 and oppositely bowed contact flanges 12 which extend in a direction normal to the plane of the base part 6. The lugs 10 engage the housing 4 at portions 37 adjacent key-hole slots 36 in a manner sequentially illustrated in Fig. 1. A detent 18, engaging the base of the housing, prevents withdrawal of the element, and flanges 14 support and locate it when in position on a printed circuit board 42, (Fig. 2). The U-shaped post 20 extends through the base of the housing, and may be soldered to printed circuit contacts 46. The housing may be of a resilient plastics material, which may be hot or cold formable, e.g. polyvinyl chloride or dichloride, or a non- polymeric material such as insulating paper. Manufacture of the housing may be by shaping in outline a strip of plastics material, punching out the slots in the base and side walls, and bending to channel-shape, after which contact elements may be inserted mechanically (Fig. 4, not shown). Alternatively, the housing may be produced by extrusion followed by a punching operation. In a modification (Figs. 5, 5A, not shown), the contact is substantially uniplanar, and has a slot in the end of each contact arm to engage a vertically extending portion of the housing. A boss (72) replaces the retaining detent 18. In a further embodiment (Figs. 6, 7, not shown), the contact element comprises a pair of tubular portions (96, 98) connected by straps (100), upstanding ears (103) engaging a portion of the housing extending parallel to the base. Contact springs (102) extend inwardly between the tubular portions (96, 98). The locking boss (101) may be replaced by a resilient detent (110) engaging a further opening in the side wall (Fig. 8, not shown). In a further embodiment, the insulating housing has a wider base (Fig. 9, not shown), so that contact tabs may be inserted from the side of the housing. Ears (138) engage the housing walls, which are sufficiently spaced for the contact to be inserted through them. In a further embodiment (Figs. 11, 12, not shown), the connector comprises two leaf spring contact members (150), from each of which is struck an upstanding ear (160) to engage the housing. The contact members are joined by an insulating yoke (164) which carries a retaining boss (165).

Title: Aquatic vehicle
IPC: B63B35/73
Filed: 1973-09-04
Abstract: A rider-balanced aquatic vehicle has a body with a seat for supporting a rider and a motor which provides propulsion for the vehicle, the front end of the body being supported by a steerable front ski and the rear end being supported by a hydraulic lifting surface on the lower surface of the body. A steering shaft is operatively connected to the front ski to control the attitude of the front ski for assisting in controlling the balance and direction of motion of the vehicle. The front ski is horizontally transversely pivoted and spring biased toward an upward and forward attitude, resulting in increased lift upon the initial movement of the vehicle and efficient planing when the vehicle is in motion. The lifting surface at the rear of the vehicle incorporates a tapering tunnel portion formed in the lower surface of the body and outwardly and downwardly extending wings joined to the side edges of the tunnel portion. The wings provide lift during straight running, but do not interfere substantially with the ability of a rider to roll the vehicle by leaning, and the tunnel gives increased lift to the rear of the vehicle during banked turns.
