The dual height workbench      . includes top members defining a working surface, a base defining    ... longitudinal and transverse axes and support structure for supporting said top members above said base.  A plurality of leg members are pivotally attached to said base adjacent outer edge portions of same and movable between inwardly folded inoperative positions corresponding to the lower height of the workbench and outwardly and downwardly inclined operative positions relative to said base corresponding to the higher position of the workbench. The pivotal attachment of the respective legs is such that each of said legs is capable of movement in an arc lying in a plane which is at an acute angle relative to the longitudinal and transverse axes of said base.  Each said leg includes at its upper end pivot axis de-fining means, with a portion of said upper end spaced from said pivot axis defining means being shaped to transmit thrust forces to said base and to limit the degree of outward pivotal motion of said leg thus to define the outwardly and downwardly inclined operative position of each leg.

Abstract: ABSTRACT OF THE DISCLOSURE          A drive for a secondary storage facility that includes a controller and a drive bus that interconnects the controller and drive. Data is transferred between the drive and controller in serial fashion over a read/write data line.  Control information, in the form of control mes-sages, is transferred between the drive and the controller in serial fash-ion over two message lines of the drive bus.  A message transfer is initiat-ed by a strobing pulse from the controller and is controlled in response to clocking signals from the controller.  During a transfer of a message to the drive, a controller-to-drive signal is asserted and conveyed to the drive.  When the message has been completed, the controller-to-drive signal shifts to a non-asserted state and enables the drive to transmit back to the controller a status message under the control of clocking signals gen-erated in the drive in response to the clocking signals from the controller that are returned to the controller over the strobing signal line.

Abstract: PISTON AND RING FOR REDUCING HC EMISSIONS                    ABSTRACT OF THE DISCLOSURE         An internal combustion engine is provided with pistons having openings connecting the space behind one of the piston rings with the crankcase during certain portions of the operating cycle of the engine.  This is accomplished by the use of a differential pressure control valve that vents the unburned hydrocarbons trapped behind the compression ring to the crankcase during periods when the pressure in the combustion chamber is at the lower values during the internal combustion engine operating cycle.  These unburned hydrocarbons are, therefore, directed into the crankcase of the engine rather than being permitted to leak back into the combustion chamber and to be discharged into the atmosphere during the exhaust stroke of the engine.

Abstract: ABSTRACT:         A device is described for the conversion of solar energy into electrical energy with the aid of a photo-vol-taic cell. A central lens forms a round radiation spot on the radiation-sensitive area of the cell, whilst a thoric mirror arranged round the lens forms an annular radiation spot. Thus, it is ensured that the entire area of the cell remains illuminated, independently of the movement of the sun relative to the cell. Owing to the selected intensity distribution in the radiation spot a satisfactory effi-ciency of the cell can be maintained even at a high concen-tration of the solar energy.

Abstract: ABSTRACT OF THE DISCLOSURE         A pair of floats and cross members are normally carried upon or in a house trailer or the towing vehicle.  When it is desired to erect the floating assembly, for example, for a suitable boat launching site, a cross member is provided which spans the rear of the floats and two longitudinal members extend from the rear cross member, to the ground or supporting surface between and adjacent the front ends of the floats.  The floats preferably should be located so that approximately two-thirds of their length is in the water with the front ends of the floats on the ground.  The trailer is then backed up between the floats with the rear bumper of the trailer sliding up the ramps formed by the longitudinally extending members.  When in position, the front of the trailer is disconnected from the car or truck and is elevated by the conventional jacking member, to a substantially level position whereupon the two longitudinal members are removed and placed between the floats and under the frame of the trailer, transversely, thus supporting the trailer between the floats with the underside of the trailer substantially level with the upper sides of the floats.  Front and rear decking is then engaged across the floats of the front and rear of the trailer and an outboard motor may be used to give propulsion to the floating assembly which is then slid fully clear of the launching site into the water.

Abstract: ABSTRACT OF THE DISCLOSURE         A pipe swivel joint for use at underwater or other submerged locations provides a system for circulating a lubricant under pressure through the joint's bearing race chamber and for monitoring the lubricant pressure to detect any leaks in the joint.  The composition of the circula-ting lubricant can be analyzed to ascertain when an out-ward leak of pipe fluid or an inward leak of sea water into the lubricant exists. The leak can be halted by changing the lubricant pressure to match the pressure of the pipe fluid or the pressure of the sea water leaking through a defective seal so that operations can continue until the leak is repaired.               -1a-

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a method of transmitting a plurality of information signals on a common carrier frequency range from different transmitters to one receiver.  The points in time at which the individual transmitters send out information signals are derived from a time base common to the transmitters and the information signals of the individual transmitters are sent out staggered timewise in relation to one another and in a manner identifying the transmitter.  The present invention is based on the object of affording a method and providing arrangements which cater for the transmission of different information signals between a plurality of transmitters and a receiver station on one transmission channel.  The invention also relates to an arrangement for carrying out the above method comprising a frequency-stable, transmitter-specific time base circuit in each transmitter for transmitter-identifying time-staggered radiation of information signals.
