Abstract: ABSTRACT OF THE DISCLOSURE            A track-seeking apparatus of a disk recorder employs a track-crossing sensor to produce track-crossing signals.  An oscillator is slaved to the sensor for supplying substitute track-crossing pulses in the absence of the sensor providing such pulses or when the radial velocity exceeds a threshold velocity.  A velocity profile means alters the oscillator frequency so that the oscillator produces track-crossing pulses in accordance with the profile.

Patent CA-2019736-A1 (CA)
IPC: H03H15/00
Filed: 1990-06-25
Abstract: A luminance signal/chrominance signal separating circuit comprises a 3 line logical comb filter for Y/C separation.  The output of the vertical correlator of the 3 line logical comb filter comprises chrominance signal components and non-correlation components of the luminance signal, whereby the separated luminance signal components have the non-correlation components missing.  The non-correlation components within the output of the vertical correlator are extracted by a trap circuit, and added to the separated luminance signal components. This prevents degradation of the oblique resolution of the reproduced luminance signal.  The noise reduction circuit in the reproduction mode shares the above 3 line logical comb filter for removing the noise of the reproduced luminance signal.

Abstract: SWAP TANK            Abstract of the Disclosure A swap tank has transverse bars disposed at the standard spacing of ISO containers and end portions extending beyond the transverse bars. Each end portion has associated with it a base frame structure including the said transverse bar and a pair of diagonal struts 14 which extend towards each other and are welded together at the tank end. A support member 24 is welded between the interconnected ends of the diagonal struts 14 and a ring 23 welded to the tank bottom 11 below the tank axis 21. The support member 24 is formed as an integral bent sheet metal part having two lateral triangular wall elements 26. To compensate for manufacturing tolerances, the support member 24 may be adjusted by varying the bending angle in such a manner that the free edges 27 of the triangular wall elem-ents 26 extend parallel and flush with the outwardly facing surface of the ring 23 and may be welded thereto. A structure is thus obtained which not only protects the projecting tank end but also serves to transmit longitudinal acceleration forces from the tank bottom 11 into the corner fittings 13 provided at the ends of the transverse bar.

Abstract: A bias ply pneumatic aircraft tire has carcass plies and/or breaker plies which are reinforced by flat nylon monofilaments.  The nylon monofilaments in the carcass plies and/or breaker plies have an oblong cross-section, and the following characteristics: at least 2,000 denier, a tenacity of at least 6 g/denier, an initial modulus of at least 30 g/denier and a shrinkage of at most 5%.  It has been discovered that bias plied composites made using nylon monofilaments demonstrate a stiffness about 20-50% greater than multifilament composites having the same approximate rivet area.  An aircraft tire made using such monofilaments shows good burst strength when built with carcass plies wherein the monofilaments have a concentration of 8-16 EPI.  Burst strength properties may be further improved by incorporating such monofilaments in breaker plies at a concentration of 8-14 EPI.

Title: Stored-spring-energy actuator mechanism for a high-voltage circuit breaker
Inventor: KUHN MAX
IPC: H01H3/24
Filed: 1991-04-26
Abstract: The stored-spring-energy actuator mechanism (210) for the high-voltage circuit breaker (218) has a spiral spring (216) which can be loaded by means of the loading device (212). The high-voltage circuit breaker (218) can be switched on once and off once with the energy stored in the loaded spiral spring (216). The energy stored in the fluid-pressure accumulator (2.58) is sufficiently great to charge the spiral spring (216) at least once.      The working-stroke movement of the piston rod (242) in arrow direction (A) is transformed via the gear segment (236) into a rotation through 360° of the gear (232) meshing with this gear segment (236). The spiral spring (216) is thereby loaded via the loading lever (230). When the three-way valve (256) is changed over, the cylinder-piston unit (214) is hydraulically connected to the low-pressure reservoir (266), as a result of which the gear segment (236) is pivoted back under the force of the restoring spring (250), and the piston-cylinder unit (214) is moved back into the inoperative position.      Unloading of the spiral spring (216) is prevented by the backstop (232), and the coupling between the loading lever (230) and the gear (232) is neutralized by a free-wheel. It is possible to drive the cylinder-piston unit (214) with thin-bodied hydraulic oil, which permits reliable working in a Wide temperature range.

Title: Safety sleeve for a borehole communicating with an underground reserve of fluid under pressure, and associated safety system, and an associated borehole operating method
Inventor: CHAIX JEAN
IPC: E21B33/122
Filed: 1991-05-09
Abstract: A B S T R A C T      In order to provide safety in a borehole communicating in particular with a cavity washed out from rock salt and containing gas under pressure, the prior art provides devices suffering from the drawback of reducing the flow sections through the tubes in the borehole.  The present invention minimizes this section reduction by means of a hollow cylindrical sleeve closed inside by a plug and including ducts formed in its wall in such a manner as to cross over the flows of fluid taking place respectively in a central tube of the borehole and in the annular space between the central tube and a peripheral tube.  In one embodiment of the present invention, the sleeve is sandwiched between portions of the central tube and of the peripheral tube, with safety valves advantageously being mounted on the portions of central tube above and below the sleeve.  This provides a safety system suitable for implementing the method of the invention by being connected in line with the central tube and the peripheral tube of the borehole.  As a result, both the flow established in the central tube and the flow established in the annular space can be stopped in the event of an accident by the valves without the valves significantly reducing the normal flow section of the central tube.  When exploiting a well in "dual completion" mode, this structure also provides significantly larger flow sections than provided by prior art tube systems.

Abstract: Abstract Of The Disclosure An improved method for plating super abrasive materials onto the working portion of a honing tool, which method includes plating or otherwise coating a relatively thin layer of a composite material comprising a metal or metal alloy material having a friction reducing or lubricating type material occluded or otherwise associated therewith over the top of the bond already established between the abrasive particles and the working portion of the honing tool so as to substantially reduce and minimize the occurrence of having stock material build-up and collect between the abrasive particles, which stock build-up causes galling or scoring of the honed work surface during a honing operation.  In the preferred embodiment, the composite material comprising the anti-galling coating surface is a nickel/phosphorous alloy material having micron-sized Teflon particles occluded therein.  The present method substantially increases the quality of the finished work product as well as the overall service life of the honing tool itself.  An improved honing tool construction is also produced through usage of the present method.
