Title: Process for the preparation of poly(hydroxy carboxylic acids)
Inventor: ICHIKAWA FUMIAKI
IPC: C08G63/06
Filed: 1994-05-27
Abstract: The invention relates to a process for the preparation of poly(hydroxy carboxylic acids) by carrying out a dehydration polycondensation of hydroxy carboxylic acids in the presence or absence of a catalyst and in the presence or absence of an organic solvent, which comprises using a vertical reactor for high-viscosity reaction mixtures in all or in some of the dehydration polycondensation steps, and carrying out the polycondensation at elevated temperature, while components of low boiling point are separated off and removed. The process allows high-molecular-weight poly(hydroxy carboxylic acids) to be prepared simply and inexpensively on a large industrial scale.

Title: Muting signal recovery and processing arrangement for RDS car radio
Inventor: WERMUTH JUERGEN ING GRAD
IPC: H03G3/34
Filed: 1994-06-21
Abstract: The arrangement includes a bandpass filter (1), logarithmic operator (2), diode (3), and low pass filter (4).  The input signal (MPX) is passed through these to produce a signal (S2).  This signal is then operated on separately by an adder (5), which increases the signal level (pref. by 0.6V), and by two independent time-constant delay circuits (6,7). The outputs of each of these circuits are fed to respective inputs of a level comparator (8) with the adder output being fed to the reference input (A).  The comparator output (S6), which is essentially a negative pulse of short time span (pref. about 8 ms), is then fed to a radio muting circuit.

Title: Process for the preparation of organic titanium compounds and their use in cathodic electrodeposition paints
Inventor: FEOLA ROLAND DR
IPC: C07C217/28
Filed: 1994-08-11
Abstract: The invention relates to a process for the preparation of organic titanium compounds and to their use as crosslinking catalysts in cathodically depositable electrodeposition coating materials. The organic titanium compounds are obtained by transesterifying tetraalkyl orthotitanates, first of all partially with alkylene glycols which are capable of forming chelates, and then to completion with hydroxyl compounds based on modified mono- and/or diepoxide compounds. Cathodic electrodeposition paints containing the organic titanium compounds prepared in accordance with the invention, after curing in a temperature range from 160 to 180 DEG C, give paint films having the properties required by users, but where it is possible to dispense with the additional use of crosslinking catalysts based on heavy metal such as lead or tin.
Patent DE-4433040-A1 (DE)
Title: Electrodeless discharge lamp of high intensity
Inventor: SOMMERER TIMOTHY JOHN
IPC: H01J61/35
Filed: 1994-09-16
Abstract: An electrostatic screen is provided between the induction coil and the discharge tube of an electrodeless HID lamp (high-intensity discharge lamp). In one embodiment, the screen is a transparent glass cylinder which is covered by a thin, transparent, conductive layer of tin oxide. In another embodiment, the electrostatic screen is a conductive, transparent tin-oxide coating with is applied either to the inside or the outside surface of a light-transmitting covering which surrounds the discharge tube. The tin-oxide layer is not continuous, in order to minimise currents induced in the conductive tin-oxide layer by the induction coil. The thickness of the tin-oxide layer is sufficient to make it conductive and to form an approximate equipotential surface, as a result of which the discharge tube and the plasma discharge are screened from intensive electrical fields, this reducing the damage to the discharge-tube wall and increasing the service life of the lamp. In addition, the tin oxide acts as an infrared reflector which guides the infrared radiation back into the discharge tube, thus leading to a higher efficiency. Other advantages of the electrostatic screen include: a lower colour temperature, further improved efficiency and a reduced formation rate of free iodine in lamps which use metal iodide fillings, thus further reducing the wall damage. <IMAGE>

Title: Electric motor drive for motor vehicle central locking device
Inventor: SAAG CHRISTIAN
IPC: E05B81/24
Filed: 1994-12-14
Abstract: The drive has a reversible electric motor with a motor shaft (4) carrying a gearwheel, a transmission with a coupling (12, 13) and reset device and a spindle (8) driven via the transmission with a spindle nut which actuates a central locking device control element. The spindle can be decoupled from the motor by the coupling to enable resetting of the control element uninfluenced by the motor.The motor shaft and spindle are mutually axially parallel and offset and are arranged in series. The spindle has a hollow gearwheel (11) on the transmission side. The transmission coupling has a pivoting pinion (12) and a tooth track. The pinion is mounted in a housing (14), engages the motor gearwheel and can be pivoted with its housing about the motor gearwheel. In its rest position the pinion only engages the tooth track (13); with increasing pivot angle it disengages from the tooth track and drives the hollow gearwheel.

Patent WO-8809924-A1 (WO)
Title: Intracavity-multimode laser spectrometer
Inventor: BOLLER KLAUS
IPC: H01S5/14
Filed: 1988-06-03
Abstract: An intracavity multimode laser spectrometer (IMMLS) is a detector for detecting various types of substance present in trace amounts in a test sample. It is particularly suitable for determining the individual concentrations of trace gases. In an IMMLS, measurement of a gas concentration is effected by intracavity spectroscopy using broad-band multimode lasers, in which coated semiconductor lasers are used as the active medium. The extreme sensitivity of this method, which far exceeds that of conventional multiple reflexion methods, is thereby extended in the infrared wavelength range from approximately 1 to 30 micrometres, in which all important molecules exhibit quantum transition and can therefore be detected. Through the use of semiconductors as the active medium and the enormous, electronically adjustable extension of the effective absorption length, a simply operated, small and robust (portable) detector can be achieved.

Title: Installation for generating electrical energy from fuels by means of electrochemical fuel cells
Inventor: LEMOINE JOSEPH
IPC: H01M8/04089
Filed: 1989-04-05
Abstract: In an economical, non-polluting installation for generating electrical energy by means of electrochemical fuel cells (1), each cell is coupled to a heat exchanger (2) and at least one gas-washing installation (11). The heat generated during the process is recovered by the heat-exchanger (2) and used to operate the fuel cells (1). The fuel residue components and expensive catalyst gas present in the fuel waste gases are separated or recovered in the gas-washing installation (11) and recycled to the fuel cells (1). A second gas-washing installation (20) and additional appliances, in particular microprocessor-based control devices, reduce the operating costs of the energy-generating installation, which is non-polluting and produces virtually no residues.

Filed: 1989-04-20
Abstract: La pré-ionisation est importante lorsque l'on veut générer une décharge lumineuse dans la cavité de gaz d'une chambre laser (LK) entre les électrodes laser (E1, E2). Dans le cas de lasers excimer du type à décharge partielle, on utilise en particulier une pré-ionisation par rayons X qui requiert des impulsions de haute tension fournies, selon l'invention, par un circuit auxiliaire composé d'une branche (Z1) connectée en parallèle au commutateur de haute tension (S) ou à la section de décharge laser (E1, E2) et qui comprend comme élément commutateur un inducteur magnétique saturable (Ls) connecté en série à l'enroulement primaire (w1) d'un transformateur d'impulsions de haute tension (Tr). C'est dans son enroulement secondaire (w2) que sont générées les impulsions de déclenchement de haute tension pour l'élément de pré-ionisation, notamment un tube à rayons X. Lorsque la branche est connectée en parallèle au commutateur de haute tension (S), elle comprend une capacité sérielle (C3); lorqu'elle est connectée en parallèle à la section de décharge laser (E1, E2), elle comprend une capacité parallèle. Ce nouveau circuit permet de synchroniser avec précision les impulsions de pré-ionisation, notamment les impulsions de rayons X, par rapport à la durée d'augmentation de la tension dans les électrodes laser, et de les accorder avec le laser.
