Filed: 1993-10-06
Abstract: A steering system is capable of steering a plurality of conveyor vehicles connected together in the form of a train.  The vehicle has a first pair of wheels which can be steered by an operator as the train moves.  There are further pairs  of  steerable  wheels  connected  to  the  second  and subsequent vehicles in the train and supporting same.  There are hydraulic cylinders for steering each of the pairs of steerable wheels on the second and subsequent vehicles and a control mechanism for controlling these cylinders in order to set the steering angle of each further pair.   This control mechanism includes means for determining the current steering angle of the first pair of wheels and generating an electrical signal indicative thereof and means for storing a series of these electrical signals as the train is travelling.  Further means determine the amount of time the wheels in the train have been travelling and there is a calculator for determining the location of each of the further pairs of wheels on the basis of the determined travel time.   A second electrical signal is generated for each further pairs of wheels in order to control its respective hydraulic cylinder and thereby set the steering angle of each pair at the same steering angle that the first pair of wheels had when they were at that location.

Inventor: BAKER GERALD S
IPC: F16K17/164
Filed: 1993-10-18
Abstract: Abstract of the Disclosure The improved valve of the present invention is a self-contained emergency safety shutdown valve which does not require the attendance of an individual or an outside power source for its emergency shutdown.  The valve illustrated is a gate valve with the gate movable between positions opening and closing flow through the valve and having a stem which is controlled by a ball shaft extending through a rotary ball nut with means for preventing rotation of ball nut in one direction and means urging stem, gate and ball shaft in a direction closing flow through the valve. The control means controlling the release of the rotation preventing  means  is  controlled by  both high  and  low pressure responsive devices which are interconnected to a plunger for operating the release and to a plunger for sensing the pressure downstream of the valve.  At any time the sensed pressure is beyond either the low or high pressure set points, the plunger is moved to operate the release and the gate is returned by the urging means to its closed position.  A means is provided by which the release means  it  held  in the release position until manually released but is easily manually release so that the gate may be opening while the control means is ineffective to cause   shutdown  until   normal   flow  conditions   are established.

Title: Improvements in hydraulic rams
Inventor: MARTIN JOHN C
IPC: F15B15/16
Filed: 1992-09-11
Abstract: There is shown a hydraulic telescoping ram of the type suit-able to tip dump trucks and the like, which permits the use of outer aggressive seals and a bore sealing device by providing a conduit which hydraulically connects the upper end of each cylinder of the telescopic ram with an oil reservoir. This makes it possible to use seals which are not aggressive and which can run on surfaces of somewhat less than top quality, on the internal bottom faces of the rams so as to allow the passage of a small quantity of oil into a gap formed within the ram and cylinder and between the aggressive and non-aggressive seals. The oil which passes the non-aggressive seal is returned to the oil reservoir when the ram is extended.

Title: Sol-gel process for forming a germania-doped silica glass rod
Inventor: KIRKBIR FIKRET
IPC: C03B37/016
Filed: 1992-12-10
Abstract: A sol-gel process for forming a germania-doped silica glass rod that is suitable for use as a preform in the manufacture of high numerical aperture optical fibers. The sol is produced by mixing together prescribed quantities of alkoxides including tetraethyl orthosilicate and tetraethyl orthogermanate, deionized water, ethanol and a precipitation catalyst such as hydrofluoric acid.  Premature precipitation of germania is avoided by adding ethanol and deionized water to an alkoxide solution at a controlled, dropwise rate and by then similarly adding the catalyst at a controlled, dropwise rate. After drying the resulting gel, sintering is performed by chlorinating the dry gel to remove residual hydroxyl groups, then oxygenating the chlorinated gel to remove the chlorine, and finally heating the oxygenated gel in helium to a temperature of about 1300 ·C. Chlorinating and oxygenating the gel for extended time durations, and maintaining the gel above 1200 ·C for less than 30 minutes, ensures that the final glass rod will not bubble when subsequently raised in temperature to 1800 ·C during the final fiber draw step.
