Title: A gearshift mechanism
IPC: F16H63/44
Filed: 1978-09-19
Abstract: A multi-speed main gear set is shiftable by a hand lever. A two- speed auxiliary gear set is shiftable by a piston-cylinder unit 8, 7, which is controlled by a control valve 10. A gearshift shaft 1 is shiftable by the hand lever as it moves to select a gate slot and is rotatable by the hand lever to engage a selected gear. The piston- cylinder unit 8, 7 is pressure-relieved by a second control valve 14 in response to a turning of the gearshift shaft 1 from its neutral position, in which the gearshift shaft is normally held by a locking piston 6. The latter is controlled by a third control valve 17, which causes the locking piston 6 to release the gearshift shaft 1 for a turning out of its neutral position only when the piston 8 of the piston- cylinder unit 8, 7 is in either of its end positions. <IMAGE>

Title: Air gauges
IPC: G01B13/08
Filed: 1979-02-15
Abstract: The apparatus (10) comprises an assembly translatable relative to the rigid sheet (31) under investigation. The assembly is provided with first and second aligned and opposed nozzles (15,26) which are adapted in operation to provide two aligned, opposed and impinging jets of fluid. The fluid jet from the nozzle (15) is of higher pressure than the fluid jet from the nozzle (26). Consequently the pressure of the fluid jet from the nozzle (26) is influenced by the impingement thereon of the fluid from the nozzle (15). A differential pressure gauge (28) which is responsive to pressure changes in the fluid jet from the nozzle (26) is provided so that the interception of the impinging fluid jets by the rigid sheet (31) upon the translation of the assembly relative to the rigid sheet (31) may be detected.

Title: Optical Measuring Instrument
IPC: G01B11/26
Filed: 1981-08-25
Abstract: An optical instrument for measuring the divergence of two approximately colinear optical axes comprises an afocal telescope (4) with a magnification of X2, and a comparator (9) disposed transversely to the longitudinal axis of the telescope, the comparator comprising a beam splitter (10), an eyepiece (11) and a graticule (12). The instrument is used in conjunction with a mirror (15) disposed orthogonally with respect to one of the optical axes, the telescope being approximately aligned with the other optical axis and disposed so that light rays passing through it are reflected back by the mirror to the beam splitter and hence to the eyepiece. The deviation of the image from the centre of the graticule determines the accuracy of the alignment. The instrument is insensitive to small inaccuracies in the telescope alignment because of the magnification factor chosen (see Fig. 2) and is particularly applicable to testing the accuracy of a gun sight, in which application it may be hand held. <IMAGE>
