Patent WO-9820313-A1 (WO)
Title: Procede et dispositif pour une analyse spectrale de la lumiere
Inventor: HERMAN PETR
IPC: G01J3/28
Filed: 1997-11-03
Abstract: Le procédé fait intervenir un phénomène physique connu sous le nom de dispersion de la rotation optique. Après passage du faisceau lumineux collimaté à polarisation linéaire par l'environnement optiquement actif (rotateur) avec un pouvoir rotatoire caractérisé par un paramètre p et ensuite par le polariseur analyseur, on peut mesurer la fonction R(p). Pour un milieu actif  donné et une orientation relative donnée des plans de polarisation du faisceau lumineux incident et du polariseur analyseur, R(p) est dans une relation non ambiguë avec le spectre I(μ) de la radiation analysée (μ représente la longueur d'onde) et permet une détermination non ambiguë, par des procédés mathématiques spéciaux. Dans des dispositifs basés sur le principe susmentionné, un faisceau collimaté à polarisation linéaire des radiations analysées se propage par le rotateur optique et passe ensuite par l'analyseur et aboutit sur un détecteur à un seul canal ou à canaux multiples mesurant R(p) en fonction du paramètre p. Finalement, le spectre souhaité est calculé à partir de la relation fonctionnelle connue entre le rotogramme mesuré R(p) et I(μ) .

Title: Coating objects with gasifiable material
Inventor: GERHARD SIEWERTH DIPL-PHYS
IPC: H01M8/12
Filed: 1969-08-25
Abstract: Maximum adherence of a gasifiable material to a metal, ceramic, plastics or glass body is achieved when the material is converted to gas adiabatically by means of a current impulse, so that it impinges on the body with higher kinetic energy. The current impulse is obtained from a charge capacitor suddenly connected across two extremities of a suitably formed piece of the gasifiable material. The material may be metal or alloy, semi-conductor, ion-conductive material, or material conductive only at high temps., and the process may be carried out in an atmosphere of protective gas or in vacuo, the body being at the same time heated or subjected to electromagnetic radiation.

Patent DE-2023608-A1 (DE)
Title: Pneumatic sifting machine-with vibratory conveyor - for coarse particles
IPC: B03B4/04
Filed: 1970-05-14
Abstract: Material is fed across a porous grid through which air is passed, and the finer particles are sucked upwards past a sieve at the top, while the coarse particles pass over a ridge and onto a vibratory conveyor to be delivered to an outlet. In another design, there is no ridge, but there is an additional sieve under the first. Alternative variations of the first design have either a side entry of air, the flow moving towards the feed entry and upwards, or entry through a slot underneath the flow moving in a similar path, both variations without the ridge. A rotary machine with similar operation has a drum which is vibrated as well as rotated, the air passing up through a central porous grid, the fine particles being sucked out through the top past a sieve, the coarse particles being discharged outwards. Another design has a non rotating vibratory durm with central air inlet and intermediate filter grids above.

Title: Zinc additions to cadmium/nickel batteries
Inventor: HIRAM JOHNSON DANIEL
IPC: H01M10/30

Patent DE-2057270-A1 (DE)
Title: Electro-slag remelting furnace - equipped with high speed electrode feed mechanism
Inventor: REDEL KARL-GEORG
IPC: C22B9/18
Filed: 1970-11-21
Abstract: In an electro-slag consumable electrode remelting furnace the rate of feed of the electrode into the bath is suddenly increased compared with the normal rate on receipt of a signal, that an electric arc has been formed. In the prefd. design this signal is given by a voltage monitoring device with a limit switch which activates a second high speed feed mechanism. The modification reduces the danger arising from arcing between electrode and mould wall, when the electrode is accidentally raised above the slag.

Patent DE-2334156-A1 (DE)
Title: Convector-type night storage heater - has thermistor on air inlet for automatic fan speed adjustment
Inventor: HEUGHAN WILLIAM CUNLIFFE
IPC: G05D23/24
Filed: 1973-07-05
Abstract: The convector-type night storage heater requires no manual adjustment of the heat release, and responds to very slight temperature changes in its automatic control, thus creating more uniform environmental conditions. The motor of a fan which takes in air through an inlet opening and delivers hot air through outlet openings is controlled by a thermistor with a negative temperature coefficient, near the air inlet. The thermistor governs the base voltage of a transistor which discharges a capacitor into the gate circuit of a thyristor circuit in series with the fan motor. This controls the motor speed and the air flow rate, as a function of the inlet air temperature.
Patent DE-2337045-A1 (DE)
Title: Telephone line transmission of counting pulses - AC signal feed determined by capacitor in series with a resistance
Inventor: FORDAN GUENTER
IPC: H04Q1/442
Filed: 1973-07-20
Abstract: The reception of the 16 kHz pulses is ensured by an amplifier and a detector which converts them into an equivalent d.c. voltage while interferences are suppressed by a delay line. The charging and discharging of capacitor C2 are controlled by a matching network with the burst of the a.c. signal limited by the time constant of the resistance-capacitance combination. The threshold gate G2 of the pulse counter z operates as a function of the charge voltage appearing across the capacitor, and triggering is determined by gate G3 connected to the output of G2. The cct. obviates the disadvantages of mechanical counters and allows shorter pulses to be transmitted.
Patent DE-2340643-A1 (DE)
Title: Accelerating fuel pump for I.C. engine carburettor - is electronically controlled to keep air fuel ratio constant
Inventor: GILEWSKI HEINZ
IPC: F02M7/08
Filed: 1973-08-10
Abstract: The pump injects additional fuel for acceleration when the accelerator pedal is moved. It has a membrane clamped between body sections with inlet and discharge passages containing ball valves. The membrane is moved by an electromagnet contained in one section of the body. An electronic circuit provides impuses which vary in length and frequency with the engine speed. When the accelerator pedal is depressed these impulses are applied to the electromagnet and their length and frequency determine the rate of pumping which is thus proportional to the engine speed and therefore to the air intake flow rate.
Patent DE-2344227-A1 (DE)
Title: Throughflow dryer for printed sheets - has exhaust and sheet feed conveyor operated only after heating-up
Inventor: LOEFFLER GERHARD
IPC: F26B21/02
Filed: 1973-09-01
Abstract: Throughflow dryer for printed sheets and lengths with air flown by a fan via nozzles and with a conveyor belt through the dryer, has the heater and circulating fan switched on while heating up the dryer, without feed of material to be dried. When the preset operating temp. is reached, the exhaust air is automatically opened or the exhaust air fan for the drying air is switched on, and the feed of material is started. Preferably, to stop the material feed during heating up, the conveyor belt for material is driven backwards against the direction of food, and is automatically changed over to forward feed when the preset operating temp. is reached. Heating up is as rapid as possible, and uniform drying is obtd. from the start.
