Filed: 1987-03-06
Granted: 1993-02-02
Abstract: Abstract of the disclosure Chloroacetic and bromoacetic acids are dehalogenated by electrolysis of aqueous solutions of these acids using carbon cathodes and anodes likewise of carbon or of other conventional electrode materials in undivided or in divided electrolysis cells; the aqueous electrolysis solutions in the undivided cells and in the cathode area of the divided cells contain, in dissolved form, one or more salts of metals having a hydrogen excess-voltage of at least 0.4 V (at a current density of 4,000 A/m ).  Metals having a hydrogen excess-voltage of at least 0.4 V (at a current density of 4,000 A/m2) are, for example, Cu, Ag, Au, Zn, Cd, Hg, Sn, Pb, Ti, Zr, Bi, V, Ta, Cr and Ni.  The process allows high current densities (up to about 8,000 A/m2) to be used without or virtually without corrosion of the electrodes and without deposit formation of the electrodes.

Title: Process of producing lithium carbonate
Inventor: BROEDERMANN PAUL
IPC: C01D15/08
Filed: 1987-05-25
Granted: 1992-03-17
Abstract: ABSTRACT OF THE DISCLOSURE:           In a process of producing lithium carbonate from decrepitable ores or ore concentrates which contain lithium, particularly from alpha-spodumene, petalite and lepidolite, the ore or ore concentrate is transformed at temperatures from about 800 to 1100°C to a form from which the lithium component can be leached,  the lithium in the decrepitated material is converted to lithium sulfate by a solubilizing roasting treatment with a surplus of concentrated sulfuric acid.  The roasted product is leached with water and the extract is  filtered from the residue,  precipitated impurities are removed from the filtrate and the latter is subsequently treated with a concentrated sodium carbonate solution to effect a precipitation of lithium carbonate, which is recovered to transform the disintegrated ore or ore concentrate into a leachable form.  The disintegrated ore or ore concentrate is transformed to a leachable form in that it is subjected to a shock heating to at least 800°C and not in excess of 1300°C as it is introduced into a circulating fluidized bed.

Abstract: KEYLESS CHUCK AND METHOD THEREFOR                ABSTRACT OF THE DISCLOSURE A keyless chuck includes a jaw housing with jaws that are advanced in respective guideways to grip a tool bit and retracted to loosen the grip on the tool bit.  A jaw thrust member is coupled to the jaws and to a threaded spindle and is forced forwardly or rearwardly to advance or retract the jaws.  The threaded chuck spindle engages the jaw thrust member through a small-area contact patch to limit the operating friction and thus provide a chuck which can be readily hand-tightened and which self-tightens in response to torque transmitted through the chuck.  A lock mechanism is provided to selectively lock a chuck adjusting sleeve relative to the jaw housing to allow uni-directional movement of the chuck adjusting sleeve relative to the jaw housing or selective bi-directional locking of the chuck adjusting sleeve relative to the jaw housing.  The lock mechanism includes a lock plate coupled to a chuck adjusting sleeve and includes a set of teeth on an axial face for engagement with complementary teeth on an axial face of the chuck adjusting nut.  The lock plate is normally spring-biased into engagement with the chuck adjusting nut and can be disengaged from the chuck adjusting nut to temporarily disable the locking mechanism.  The keyless chuck is assembled in such a way that the run-out of the finished chuck is minimal.

Abstract: ABSTRACT OF THE DISCLOSURE         A wavelength selective optical recording and reproducing device has a reference wavelength in a marker hole of a medium.  The optical detector is adapted to detect light which is reflected from or transmitted through the marker hole.  A phase detector detects the phase of an output of the optical detector by using a high frequency signal as a reference to obtain a signal indicative of the deviation of the wavelength of the output from a desired wavelength.  A wavelength regulator is responsive to the wavelength deviation to control the wavelength of the light source to be the desired wavelength.

Abstract: Abstract of the Disclosure Modulating Inchina Valve With Automatic Pressure Control Inching valves for providing controlled slow movement of a vehicle normally have valve means therein to control the pressure level of the fluid being directed to the driving clutch of the vehicle.          Upon release of the pedal, a sudden jerk of the vehicle may occur.  The modulating inching valve of the subject arrangement provides a housing having a valving menas slidably disposed therein and operative to selectively block communication between an inlet port and an outlet port.  The modulating inching valve further includes an input actuator mechanism operative to selectively control the valve means in response to the position of the operator's inching pedal.  Through a portion of a predetermined travel distance of the input mechanism the operator controls the rate of pressure being supplied to the fluid actuated device and during the remaining portion of the predetermined travel distance the modulating relief valve automatically controls the rate of pressure rise.  The modulating inching valve provides a compact arrangement allowing selective control of the pressure level to the fluid actuator device at lower torque levels within the clutch but inhibits the operator's ability to control the rate of pressure rise to the clutch during higher torque levels.  This eliminates undue heat and abnormal wear of the elements and further eliminates the tendency of the vehicle to jerk if the inching pedal is fully released quickly.
