Title: Valve for controlling heat exchanges in an oil circuit
Filed: 2013-07-08
Abstract: A valve for regulating the temperature of an oil flow, includes a first inlet channel, a second inlet channel and an outlet channel, the second inlet channel and the outlet channel being capable of cooperating with a temperature regulator. One of the inlet channels includes an oil flow regulator controlled by a computer by generation of an electrical set value respecting a control law configured within the computer, the control law being slaved by an oil flow temperature sensor, the electrical set value controlling opening and closing of the regulator, the regulation law generating an alternation of open and closed states of the flow regulator so as to achieve a required average temperature of the oil flow over a given period.

Title: Production of thiophenols
Inventor: SKRZEC ADAM EDWARD
IPC: C07C313/00
Filed: 1980-03-31
Granted: 1983-07-28
Abstract: A thiophenol is produced by a process which consists in reacting hydrogen sulfide and a source of hydrogen with a halogenated aromatic compound. The total conversion of the reaction is improved by increasing the reaction temperature as the total conversion decreases optionally independently of the presence of hydrogen. The process produces high yields of thiophenol with low quantities of byproduct aromatic thioethers, particularly diphenyl disulfide.

Filed: 1982-01-12
Granted: 1985-08-01
Abstract: A water pressure driven massage apparatus has a casing carrying a plurality of captive massage members in the form of balls. The balls are mounted in guide passages with some clearance to move inwardly and outwardly with respect to the casing. When the device is pressed against a body part to be massaged, the balls are pushed back against an eccentric projection on a water-driven turbine, causing them to follow a periodic massaging stroke. When not pressed against a user, the balls are forced by water pressure to an outermost position at which the guide passages are sealed by the balls against flow and the water then passes through spray jet guides are provided in the surface of the casing.

Title: Apparatus for reproducing video signals with a speed which deviates from a nominal speed
Inventor: SPIERO RICHARD CEES
IPC: G11B15/467
Filed: 1983-04-18
Granted: 1989-11-16
Abstract: A video recorder wich is adapted to reproduce video signals recorded on a record carrier in the form of a tape in tracks which are parallel to each other and which are inclined relative to the longitudinal axis of the record carrier with a speed which deviates from the nominal speed. The video recorder comprises tracking-error detection means for detecting the deviation of the read head from the centre of the track to be followed. The generated tracking-error signal is applied to the tape-transport control loop. For the purpose of tracking-error detection a reference-signal generator generates reference signals which form an identification for the track to be followed. For reproduction with a deviating speed these reference signals are generated in such a pattern that this pattern corresponds to the sequence of tracks which the head would scan in the case of a free uniform motion with a constant-tape transport speed which deviates from the nominal speed, so that when such a pattern is generated the tape-speed control will establish a tape-transport speed corresponding to this pattern.
