Abstract: File No. 720-10 ABSTRACT OF THE DISCLOSURE            Apparatus for accurately timing an event relative to clock signals The apparatus given an indication of the location in time between two successive clock signals of an event to be timed.  Such an event may be the arrival of a laser pulse at a satellite.  An integrator circuit (C84) is charged by a relatively high charging current from a first current generator (66) during the period of time between the event and the next clock signal.  The integrator circuit, is then discharged by a smaller current of opposite sign from a second current generator (80).  The ratio of the charge and discharge currents "stretches" the inter clock pulse time interval to a length that can be measured by counting clock pulses as the integrator discharges. For this factor to be useful, it is essential that the charging current remains constant during charging and from one charging occasion to the next.  This is achieved by keeping the generator (66) generating current constantly and by diverting the current through an integrator circuit by-pass (R78) when not integrating.  Switching is done using two transistors (Q71 and Q72) that are as identical as possible, and independently controlled in phase opposition. The by pass current is detected and used to regulate the gene-rator (66). Provided both transistors deviate in the same manner from nominal characteristics, this provides accu-rate compensation for variations in the other transistor also.

Abstract: Abstract The invention relates to an arrangement for detachable coupling of a trailer equipped with pivoting wheels to a ball hitch of a vehicle.  At the forward end of the trailer there is a coupling receptacle to receive the ball hitch and a locking member to lock the ball hitch in the coupling receptacle. In order to prevent the trailer rotating about a vertical axis through the ball hitch two opposing stops are fitted at the forward end of the trailer at such a distance from each other in the lateral direction that when the trailer is coupled to the ball hitch of the vehicle the stops bear against corresponding opposing stop faces at the rear end of the vehicle.

Abstract: ANKLE EXERCISER            ABSTRACT     An ankle exerciser (10) is disclosed for permitting isokinetic exercise of the ankle joint of the user. The foot of the user is secured to a foot plate (54) by a strap (124).  The foot plate is capable of motion about three mutually perpendicular axes (X-X, Y-Y, Z 2), with one axis corresponding to the axis of pivotal motion of the ankle joint in dorsal and plantar flexion.  The motion about each axis is restricted by a double acting fluid cylinder (64, 82, 104).  Individual metering valves (160, 162, 164) are provided for restricting flow between the chambers of the cylinders and a reservoir (152) to selectively determine the desired resistance to motion.  Pressure gauges (l54, 156, 158) are associated with each of the fluid cylinders to indicate the force exerted by the user resisted by the particular fluid cylinder.  In a second embodiment, an ankle exerciser (250) is provided for exercising both ankles of the user.  The foot plates (282, 284) are provided with straps to secure the feet of the user thereon.  The foot plates are mounted for motion about an axis (V-V) which substantially corresponds to the axis of pivotal motion of the ankle joints in dorsal and plantar flexion.  A fluid cylinder (296) and metering valves (304, 306) permit resistance to motion of the foot plates and permit the resistance in each direction to be independently determined.  Pressure gauges (300, 302) are provided for monitoring the force exerted by the user.

Abstract: INVENTOR :  JOSEPH SARTOR          INVENTION:  DRAINAGE SYSTEM FOR             HORIZONTAL SURFACE     ABSTRACT OF THE DISCLOSURE     A drainage system for a horizontal surface such as that defined by a structural concrete panel is described.  The drainage system includes a cladding constructed of a multiplicity of rectangular panels in edge-to-edge abutted relationship placed over the horizontal surface.  An upper face of each panel has a criss-cross network of intersecting grooves which place side edges of the panel in fluid communication with other side edges.  The opposing, lower face of each panel has a second criss-cross network of inter-secting grooves which also place the side edges of the panel in fluid communication.  The depths of the grooves are such that the first and second networks intersect at a multiplicity of points so that water can travel between the opposing faces of the panels.          Each panel has water-permeable filter material cover-ing the upper face of the panel.  Thus, in a typical application such as landscaping in which dirt is deposited on the cladding or the provision of a terrace above a parking garage in which gravel is deposited on the cladding to support a deck, any dirt entrained by water flowing into the cladding does not enter the grooves of the panels.  The generally horizontal surface of the concrete slabs can be slightly inclined and provided with appropriately positioned openings to permit removal of water from the panels of the cladding.
