Title: Voltage elevating circuit for use with photocell includes control circuit and reference voltage regulating switching transistor operating with self inductance
Inventor: FARINE PIERRE-ANDRE
IPC: G05F1/67
Filed: 1997-02-17
Abstract: The circuit uses an inductance to raise the 0.3 v supply from a single cell to approximately 1 v to operate the watch circuit.  In the voltage elevating circuit, the voltage on the terminals of the photoelectric source (1) is controlled as a function of a reference voltage (Vref) which is chosen to correspond to the peak of the power-voltage curve of this source. The reference voltage generated in the reference voltage generator (9) is compared to the voltage (Vsc) of the source. The result of this comparison is sampled and influences the cyclical ratio of a control signal (Fc) applied to a switching transistor (7). The switching transistor is arranged to cut the current flowing from the source towards the load (accumulator 6), via a self-inductance (4) and a diode (5).

Patent CH-686682-A5 (CH)
Inventor: GORDON OTTO
IPC: D21C11/00
Filed: 1992-05-05
Abstract: PCT No. PCT/CH93/00108 Sec. 371 Date Jan. 5, 1994 Sec. 102(e) Date Jan. 5, 1994 PCT Filed Apr. 30, 1993 PCT Pub. No. WO93/22492 PCT Pub. Date Nov. 11, 1993A process for the production of cellulose from wood and annual plants is provided where the digesting liquor contains free caustic soda, sodium salts of alkyl benzenesulfonic acids, and of aromatic or aliphatic carboxylic acids. By the addition of anthraquinone or its derivatives to the digesting liquor, the delignification is improved. Anthraquinone is resistant to wet oxidation and can be reintroduced into the digesting process. The solubility and, therefore, the effectiveness of anthraquinone is improved by the use of sulfonic acid salts. For the recovery of the digesting chemicals contained in the black liquor, solubilized liquor is precipitated with mineral acid or carbon dioxide and the hemicelluloses are separated by ultra filtration. The resins are separated by extraction with the residual organic compounds, except for the sulfonates and carboxylics, being burned in an aqueous phase with air and/or oxygen. The solution of chemicals containing no further wood decomposition products can, by caustification of the carbonates, be transformed into caustic soda and after partial crystallization of the aliphatic carboxylics used for the cycle of pulp production. The sodium acetate isolated by crystallization can, by membrane electrolysis, be split into acetic acid and sodium hydroxide. The caustic soda is reintroduced to the digesting process, while the acetic acid is treated separately.

Title: Overvoltage suppressor
Inventor: NAGAI NOBUO
IPC: H01T4/20
Filed: 1976-05-04
Abstract: An earthed metal housing (10) is hermetically sealed at one end by means of a closure plate (24), and an electrical insulating body (44, 46) extends through the other end, which is likewise sealed by a closure plate (18). In consequence, a space (60) which is filled with an electrically insulating gas, is formed inside the housing (10). An overvoltage suppressor element (66, 70) in the gas-insulated space (60) is connected on the input side to an insulated conductor (52) which passes through the insulation body (44, 46), and on the earthed side is electrically connected to the housing (10). The input side of the overvoltage suppressor element is surrounded both by the insulation body (44, 46) and by a screening body (54) which is embedded therein. This overvoltage suppressor can in consequence be designed to be significantly smaller than suppressors which have been known until now, while maintaining the same suppression characteristic. <IMAGE>
Patent CH-640617-A5 (CH)
Inventor: ANDREOLLA FLORIAN
IPC: B23B5/36
Filed: 1979-07-06
Abstract: The connecting piece includes a hollow many-sided head and a hollow screw which forms one piece with the many-sided head. The screw is provided with an external thread so that it can be screwed into the internal thread of a part of a line or an apparatus. A chamber-like circular recess is worked from below into the many-sided head in the proximity of the end of the thread of the screw. The circular recess is worked into the many-sided head in one operation. The cutting tool is first guided into a gate at the end of the thread of the screw perpendicularly to the longitudinal axis of the connecting piece. Thereafter the cutting tool is guided into the bottom surface of the many-sided head in parallel with the longitudinal axis of the connecting piece. In this way a guide surface at the end of the thread of the screw is formed which is free of obstacles. The insertion of the sealing ring into the circular recess is simplified because the sealing ring is guided along the guide surface into the recess without a great effort and without being injured. By tightening the connecting piece the deformation of the sealing ring is limited in an optimal way because the metal of the many-sided head lies on the metal of the part to be connected.

Title: Process for making pressed-diamond wire-drawing dies and product from this process
Inventor: CHO HYUN SAM
IPC: B21C3/18
Filed: 1981-11-20
Abstract: A process for making pressed-diamond wire-drawing dies of the type is described, which can generally be described as an inner polycrystalline diamond mass which is surrounded by a mass of metal-bonded carbide such as, for example, cobalt/sintered tungsten carbide and bonded thereto. It is known to make these drawing dies by high-pressure/high-temperature processes, typical conditions being 50 kbar and temperatures above 1300 DEG C. The improvement according to the invention comprises providing a group of discs of specific materials in specific arrangements within the reaction subassembly (for example metal carbide and diamond inside a zirconium cup). For example, a disc of a diamond catalyst/solvent and a disc of a refractory metal such as molybdenum are arranged on one side of the mass of metal carbide and diamond, and at least two discs of one or more transition metals such as zirconium are arranged on the other side. These discs are in general introduced into the interior of the subassembly cup. By means of this process modification, the process yields have been considerably improved by reducing the occurrence of defects in the drawing dies and by shortening the reaction time.
