Title: Pyrocatechol prodn - by hydrolysing 2-chlorophenol
IPC: B01J27/00
Filed: 1973-08-01
Abstract: Pyrocatechol (useful as an inter for plant-protection agents) is produced by hydrolysis of o-chlorophenol with 3-7 molar proportions of alkali hydroxide in aq. soln in the presence of a Cu cpd. as catalyst at normal or slightly reduced press and elevated temp. with subsequent acidification of the reaction mixt. The catalyst is a soln obtd. by dissolving a Cu(II) cpd. (or a Cu(I) cpd. with the simultaneous action of an oxidising agent) in conc. aq. alkali hydroxide in the absence of phenols. The o-chlorophenol (opt. dissolved in aq alkali) is added to the catalyst soln. as rapidly as possible at 160-215 degrees. Pressure vessels are not required for carrying out the process and iron reactors can be used. Reaction temp. are relatively low, and reaction times are relatively short. Yields of pyrocatechol and conversion of o-chlorophenol are higher than with prior procedures.

Title: Speed regulator for car - with variable length element in throttle linkage lockable by electromagnetic bolt(NL250177)
IPC: B60K31/10
Filed: 1975-07-23
Abstract: The speed regulator for the car comprises a telescopic element (10) in the throttle linkage. This element is normally locked into a fixed length by an electo-magnetically operated bolt (27). This enables the vehicle to be driven normally. If the drier requires the vehicle to maintain a set speed he first accelerates to that speed. Then he pressed a control button which releases the telescopic lock. An electronic control then takes over. Theis compares the actual speed with the set speed and generates correction signals for the servo element (15) which controls the throttle setting. To cancel the speed regulator the pedal is depressed to reach an end stop switch (27). This enables the driver to override the setting in order to accelerate past a vehicle.

Patent FR-2295140-A1 (FR)
Title: Cell for electrolysis of koch-salt solns - in which current leakage is confined to predetermined anode zone (BE180676)
IPC: C25B9/19
Filed: 1975-12-17
Abstract: A pre-formed, non-conductive frame or body section for an electrolytic cell has the "filter-press" configuration, each frame having two electrodes and being divided into two compartments (anolyte and catholyte) by a membrane. Extensions forming manifolds for delivery, removal and drainage (for shut-down) of the electrolyte are integral with the frame and connected to the appropriate chambers by borings through the frame wall. The novelty lies in the provision of conductor made of suitably resistance material which connects the anode with electrolyte in the overflow or drainage manifolds and which passes through the passage connecting the anolyte compartment with the overflow or drainage manifold for the electrolyte. The conductor permits a small current flow from the anode to the liq. in the manifold(s) and thereby prevents current leakage from parts of the anode other than those with which the conductor is in contact. Anode life is extended to 1-5 years by control of current leakage area.
