Patent EP-0036424-A4 (EP)
Title: Circuit arrangement for an asynchronous motor drive with variable speed.
Inventor: GYORGYI VIKTOR
IPC: H02P8/00
Filed: 1981-04-21
Abstract: A circuit arrangement for an asynchronous motor drive of controlled stepping, i.e. for control of the number of revolutions of asynchronous squirrel-cage motors, in which the output of the supply unit is connected to a potentiometer, the other terminal of which is connected to the common terminal of the abjusting resistors. The non-common terminal of one of the resistors is connected to one of the inputs of a switch-inductance, whereas the collector of a transistor is connected to the other input. The emitter of the transistor is connected to the negative pole of the supply unit, while one switching point of the switch-inductance is connected to one of the inputs of the NAND-gate having several inputs. There is a magnetic coupled control coil arranged in the system being common for the switch-inductance and the uncoupling coil, while there are as many circuits of identical layout consisting of the switch-inductances, the single abjusting resistors and the transistors, as the number of pulses required for the control. The NAND-gate is connected through a switch-amplifier to the control input of the inverter.

Patent EP-0059712-A4 (EP)
Title: Improved load-plus valve for variable displacement pumps.
Inventor: RUSEFF WALTER Z
IPC: F16H61/433
Filed: 1980-09-12
Abstract: A "load-plus" valve is oftentimes utilized in the servo-system for a variable displacement pump to maintain pump discharge pressure above a minimum pressure level and above a load pressure in a fluid actuator. Valves of this type normally employ a spring interconnected between a modulating spool and a piston which is responsive to load pressure to modulate a control pressure, controlling the displacement of the pump. Valves of this type thus provide a constant discharge pressure margin over load pressure while also providing the pump's minimum standby pressure. However, valves of this type further provide pump packages which are somewhat bulky in design. The improved load-plus valve (22) of this invention provides a spool (49) movable between a first position communicating a control pressure (P<uC>u) from a pump (11) to a control chamber (24) and a second position at least partially venting the control chamber (24), and a piston (57) movable between a first position isolating the piston (57) from the spool (49) to enable the spool (49) to move independently of the piston (57) and a second position engaging and moving the spool (49) to modulate the control pressure (P<uC>u) in response to variations in a load pressure (P<uL>u) in a fluid actuator (13).

Title: Process for clarifying bicarbonate bearing waters using measurement and control of carbon dioxide content.
Inventor: NICKSIC STEPHEN W
IPC: E21B43/40
Filed: 1985-02-07
Abstract: Process for achieving and maintaining the clarity of bicarbonate bearing waters. The process has application to treating bicarbonate bearing waters where such waters are for injection into a subsurface formation, for waste disposal, or for any other industrial purpose where bicarbonate bearing waters may need to be treated. The process is intended to prevent an imbalance in the bicarbonate/carbonate equilibria in bicarbonate containing waters as the water is treated in a treatment process. The process involves the measurement and control of carbon dioxide content to prevent the deposition of both organic and inorganic solids. By use of the process the specifications on turbidity and suspended solids content in treated water can be met with a significant decrease in, or possibly elimination of, the dosage of other treating chemicals.

Title: Zinc oxyfluoride transparent conductor
IPC: H01L31/0216
Filed: 1990-03-14
Abstract: Transparent, electrically conductive and infrared-reflective films of zinc oxyfluoride are produced by chemical vapor deposition from vapor mixtures of zinc, oxygen and fluorine-containing compounds. The substitution of fluorine for some of the oxygen in zinc oxide results in dramatic increases in the electrical conductivity. For example, diethyl zinc, ethyl alcohol and hexafluoropropene vapors are reacted over a glass surface at 400 DEG  C. to form a visibly transparent, electrically conductive, infrared reflective and ultraviolet absorptive film of zinc oxyfluoride. Such films are useful in liquid crystal display devices, solar cells, electrochromic absorbers and reflectors, energy-conserving heat mirrors, and antistatic coatings.
