Title: Composition and method for removing water and aqueous leak tracer solutions from fuel tanks
IPC: C10G33/04
Filed: 1981-01-06
Abstract: Combination of a nonionic oxyalkylated alcohol surfactant and an engine fuel, (e.g. a 50-50 mixture, by volume), which is miscible both with water-based and oil-based liquids, for removing water or water-based leak tracer solution entrapped in a fuel tank system. When employing, for example, an aqueous leak tracer solution introduced into a fuel tank, for locating any leaks therein, after inspection and removal of the main body of leak tracer solution from the tank, in order to remove any residual leak tracer solution which remains entrapped in the tank, the invention composition, hereinafter termed a "depuddling agent", is introduced and blends with the residual leak tracer solution, and the resulting miscible mixture is drained from the system. Any remaining portions of such mixture are miscible with the subsequently introduced oil or petroleum-based fuel, and the resulting mixture also can be drained from the system or burned out by the aircraft engines during test runs.

Patent GB-2070156-A (GB)
Title: Hydrostatic Bearing
IPC: F16M5/00
Filed: 1981-02-26
Abstract: The invention relates to hydrostatic bearings and seeks to provide a bearing design which affords a reduced consumption of pressure medium without increased risk of bearing breakdown as a result of inlet path blockage. According to the invention an hydrostatic bearing comprises a bearing portion (1) provided with bearing pockets (6), and a mounted portion (2) with a bearing surface (3). Pressure medium is supplied through an inlet duct (7), which extends towards the bearing surface (3) of the mounted portion (2). The end faces (10) of the inlet duct (7) and the corresponding surface (3<1>) of the mounted portion (2) form an annular throttle gap (11). A choke valve (12) may be mounted in series with the throttle gap (11) in the inlet duct (7). Because of the throttle gap (11), the effective cross section of the inlet duct (7) or choke valve (12) if used, can be made larger, thus reducing the risk of blockage of the inlet path. The annular throttle gap (11) is self-cleaning, since it consists of two parts (1) and (2) moving relative to each other. <IMAGE>

Title: Motorcycle jack stand
Inventor: CLINE JACK B
IPC: B62H1/02
Filed: 1982-08-06
Abstract: A motorcycle jack stand comprises a pair of spaced-apart stanchion assemblies (34,36) which are mounted on the undercarriage of a motorcycle. The stanchion assemblies (34,36) are movable in unison between a stowage position and an extended position. When in the extended position, each stanchion assembly (34,36) includes a movable member (40,46) which is extended to come into contact with the ground or street. Within each stanchion assembly is included a ratchet assembly which permits each movable member to further extend, but prevents withdrawing movement. Lateral rocking of the motorcycle causes sequential extension of the stanchion assemblies resulting in at least some portion of the weight of the motorcycle being supported by the stanchion assemblies with the motorcycle positioned vertically upright. The motorcycle jack stand can be operated either by hand or by feet. Initial forward motion of the motorcycle will cause the motorcycle jack stand to automatically retract to the completely stowed position. <IMAGE>

Title: Preprinted master sheets and continuous process for producing same
Inventor: MAZER DAVID K
IPC: B41M5/035
Filed: 1982-10-04
Abstract: Master sheets having image-to- image registry of material printed on both sides of such masters and produced by a continuous printing process. An offset, letterpress, gravure, of flexographic printing process 12 is used to print images on one side of a continuous web 11. On the opposite side of the web reverse images are printed in registry with the images on the first side of the web using a rotary screen press 22 and a fluid hot melt or solvent-based ink. After printing, the web is cut into individual masters which are then stacked or collated and assembled into booklets. The masters can be used for spirit duplicating processes or iron on transfers. The first-side printing may be omitted. The web preferably enters a rotary screen printer horizontally, and leaves it inclined upwardly at an angle of 0.5 DEG  to 6.0 DEG  to the horizontal before being cut. Protective material 36 may be applied to the master image. <IMAGE>

Title: Method of establishing a rotating priority in a daisy chain
Inventor: GARMAN JONATHAN D
IPC: G06F13/37
Filed: 1982-11-04
Abstract: Modules 4 are arranged in a daisy chain of modules contending for control of a commonly shared bus line, 2. Each module provides a GROUT signal 6 in response to an input signal 8 GRIN, if it is not contending for control of the bus. However, if it is contending for the bus it inhibits the GROUT 6 signal from being propagated further down the chain and awaits a GRIN 8 signal to determine when it can take control. Each module is able to sustain the state information that it had control of the bus last by producing a last access signal 4. The module that had control in the previous bus cycle now has the lowest priority for access. Thus the priority rotates around the daisy chain. <IMAGE>
