Abstract: HYDRAULIC SAFETY MECHANISM              ABSTRACT OF THE DISCLOSURE         Three embodiments of a hydraulic safety mechanism are adapted to adjust the speed setting for an engine upon a reduction of pressure in a chamber, due for example, to loss of lubricating pressure, overspeeding of the engine or overheating, for example.  In each embodiment, a speed control element for the engine  is   maintained in a normal operating position by a piston and cylinder combination which hydraulically blocks the chamber from the fluid drain in a normal operating position, the piston responding to reduced pressure in the chamber by communicating the chamber with the drain the piston thereby being hydraulically unlatched and permitting the speed control element to be repositioned to a reduced speed setting.  A restrictive orifice, preferably of variable size and self-cleaning construction, regulates com-munication between the hydraulic circuit and the chamber.  In another embodiment the safety mechanism includes a solenoid and accumulator chamber to adapt it for remote operation.

Abstract: TOOL FOR POSITIONING IMPLANTABLE MEDICAL PROSTHETIC DEVICE AND METHOD OF USING SAME                      ABSTRACT OF THE DISCLOSURE   The tool comprises a hollow barrel having an obturator slidably mounted therein and having a rounded forward end.  A locating device is attached to the barrel to stabilize the obturator in the plurality of predetermined positions as it is moved along the bore of the barrel.  A needle having suture material attached may be placed within the bore of the barrel.  A slot is located along the length of the barrel to allow the suture material to exit from the side of the barrel.  In practice, the tool may be inserted into a bodily structure such as one of the corpora cavernosa of a penis.  The outer surface of the barrel is equipped with a plurality of markings that allow the user to gauge the depth that the barrel has been inserted into a bodily structure.  After the tool is inserted, the obturator is slid along the barrel bore to force the needle out of the rounded forward end of the barrel.  The needle is manually pulled out of the bodily structure.  After the tool is withdrawn, suture material remains threaded through the bodily structure.

Abstract: ABSTRACT OF THE DISCLOSURE A main valve is connected into a pressurized water pipe for an irrigation installation and has a valve body in the form of a differential piston and with a through bore.  The body is operated in both directions by means of the water pressure.          The  piston in one end position closes the water pipe and in its other end position keeps it open.  The piston is guided to said end positions by means of a control valve adapted to open or close a duct extending from the major cylinder bore, to cause the water present to actuate the piston.  The control valve is in turn controlled by rainfall onto, and evaporation from an upwardly open bowl and a drop means active during irrigation.          The bowl is part of a tipping means with two tipped end positions controlled by the quantity of water in the bowl.  To achieve operation of the main valve such that irrigation substantially takes place at night, and that the length of time between irrigation can be varied, the tipping means is supplemented by a closed air chamber on the other side of a pivoting  shaft, said chamber and bowl having a common flat bottom and mutual communication via a slit at the bottom.  By the volume change in the air enclosed in the air chamber, caused by the temperature difference between night and day, the quantity of water contained in the open bowl and in the chamber is displaced at night such that  the tipping means tips over into a position opening the main valve.

Abstract: HEAT EXCHANGE SYSTEM     Abstract A plurality of parallel heat exchange tubes are grouped together and connected at the ends to form a bank.          One or more banks are positioned so that one end lies in a supply air stream and the other end lies in an exhaust air stream.  Each bank of tubes is sealed and contains a working fluid of the type having a liquid phase and a vapor phase. At one end of each tube, the working fluid absorbs heat from one of said air streams to effect vaporization of said fluid, the vaporized fluid flows to the cooler end of said tube where said vaporized fluid gives up heat to the cooler air stream and condenses in the tube.  The condensed fluid then flows back to the warmer end by means of gravity.  One end of the lowest tube in each bank includes a reservoir connected thereto which communicates with the normally cooler air path and in-cludes a heating coil operatively associated therewith for providing a modulated control of the system responsive to the temperature of the enclosed space being ventilated.  Additionally, a second control system turns selected banks of heat tubes on and off to prevent frost from forming thereon.

Abstract: ABSTRACT         Disclosed is a fixed hard disc drive, including a hermetically sealed housing with an air cleaning means, for use in connection with micro-computers and other data handling equipment.  The drive assembly includes a cylindrical portion and a rectangular portion.  A plurality of discs are supported on a drive shaft for rotation in the cylindrical portion and an external disc drive mechanism drives the shaft.  A filter is disposed at one end of the rectangular portion and has an input side disposed to receive air which is pumped by the rotating discs and provides clean air to the center of the disc and spindle whereby the air can travel outwardly over the disc to cleanse it.  A plurality of magnetic heads are supported in cooperative relationship with the disc surfaces and a head support and drive assembly at the other end of the rectangular housing moves the heads into cooperative relationship with the discs.  An external motive mechanism drives the heads to various radial locations on the disc surfaces.  The disc drive is plug compatible with conventional floppy disc drives but the hard discs have higher storage capacity.

Abstract: ABSTRACT           A constant-tension spring device for the accessory belt of an automobile engine.  The device includes a cylinder having an elastomer ring mounted within each of its ends.  A rod passes through each elastomer ring, the rod having spaced shoulders each bearing against one end of a respective elastomer ring.  Abutments within the cylinder position and retain the elastomer rings.  Upon sufficient axial motion between the rod and cylinder, the elastomer rings are distorted by twisting and display a flat segment of the load vs. deflection curve between the rod and cylinder.  The spring device maintains a desired tension within the accessory belt, compensating for temperature, humidity, and ageing changes in belt length which would otherwise result in change of belt tension.

A circular base contains N columns T1,  T2,..Ti,..TN of electroacoustic trans-ducers.  To  each  column,  such  as  Ti,  corresponds  a transmission at the frequency fi.  A switch makes it possible to change from transmission to reception. The signals  received  are  applied  to  a  channel  forming device. For each channel, such as Vk, the signals are filtered at frequencies f1, f2..fN, which are applied to time offset circuits taking into account the base geometry  and  the  channel  direction.  The  signals obtained, such as di.k, are applied to a display device which supplies the range, direction and speed of the targets detected.  This is particularly applicable to underwater surveillance by sonar or radar.
