Patent DE-4239003-A1 (DE)
Title: Sun protection with light directing properties - involves lamellas of specific cross-sectional configuration with undersides having profiling providing predetermined light direction for diffuse sky radiation in room
Inventor: SCHOLZ CHRISTIAN DIPL PHYS
IPC: E06B9/24
Filed: 1992-11-19
Abstract: At least a part of the diffuse sky radiation coming into the upper side (6) of the lamellas (2) is reflected on to the underside (10) of the lamellas above and from there is directed into the room by the profiling. Viewed in the cross-section of the lamellas, the profiling comprises curve segments of variable pitch arranged one behind the other, i.e. curve of the second or higher arrangement. The curve axis of the corresp. curve segments run inclinedly and/or vertically to the main axis (8) of the lamellas (2) and the profiling is formed concavely and/or convexly. USE/ADVANTAGE - To protect a room against direct sunlight, and to control the degree of diffuse light coming into the room.

Title: Prodn. of bees-wax candles - by rolling honeycomb middle wall around wick under compression
Inventor: ZORELL DIETER
IPC: C11C5/00
Filed: 1992-11-24
Abstract: Prodn. of wax candles comprises preheating a 'middle wall' to 32-43 deg.C and rolling it around a wick under compression from the outside towards the wick. N.B., middle wall is a bee-keeping term for a wax plate inserted in a hive to form a base for honeycomb construction. Pref. the middle wall is preheated to 35-41 (esp. 36-40) deg.C. ADVANTAGE - Compression reduces the depth of the honeycomb indentations on the surface of the candle without completely levelling them. This reduces the dust-collecting tendency of the candles and improves their burning characteristics without impairing their appearance as natural prods..

Title: Conveying device
Inventor: KELLERT HANS-DIETER ING GRAD
IPC: B23Q7/18
Filed: 1993-02-10
Abstract: A carriage (1) movable on straight guides (2, 3) has at each of the two longitudinal sides two centring arms (8-1) pivotable over it. These centring arms (8-11) are driven by two drive gears (16, 17) which during the feed of the carriage (1) in each case slide along a strip (22, 23) orientated at an angle to the direction of movement of the carriage (1) and consequently impose a rotary movement on the drive gears (16, 17). A spring (26) enables the strips (22, 23) to be pivoted out of the path of movement of the pins (18, 19) as soon as the centring arms (8-11) can no longer be pivoted. <IMAGE>

Title: Method for liquefying gases, characterised in that liquid gas is evaporated at high pressure, expanded, liquefied, supercooled and, in a half-open cycle, is used for cooling
IPC: F25B9/06
Filed: 1993-02-16
Abstract: 1) Method for liquefying gases, characterised in that liquid gas is evaporated at high pressure, expanded, liquefied, supercooled and, in a half-open cycle, is used for cooling. 2) The previous methods for gas liquefaction require up to several stages and a correspondingly high cost in terms of installations and energy. 3) Liquid gas is delivered by a pump under high pressure into a heat exchanger and is evaporated there by supplying heat (e.g. waste heat or ambient heat). The vaporous or gaseous gas is expanded, involving a large drop in pressure, and in the process is cooled down to liquefaction, and supercooled. The supercooling of the liquid gas is utilised for cooling and liquefaction of gaseous gas in a liquefaction and collection vessel, the gaseous gas flowing in from a separate container or being forced into the heat exchanger by means of a compressor. A portion of the liquid gas flows back into the circuit, to the pump. 4) The novel, simplified method for gas liquefaction reduces the cost in terms of installations and energy.

Title: Method and device for pressure measurement and/or detection of air bubbles in flowing media
Inventor: DOLAG NORBERT
IPC: A61M5/36
Filed: 1993-03-11
Abstract: The invention describes a method and device for pressure measurement and/or detection of air bubbles in flowing media. The medium flows in an elastic tube which is irradiated with ultrasound waves in firm contact with an ultrasound emitter and an ultrasound receiver. The measured intensity of the ultrasound is a measure of the pressure in the tube, so that air bubbles can also be detected. The advantage of the invention resides in a quick, simple and very sensitive monitoring of a flowing medium, especially in infusion therapy.

Patent DE-4318884-A1 (DE)
Title: Method for the operation of a machine tool or of a robot
Inventor: SCHLEICHER SIEGFRIED DR
IPC: G05B19/4155
Filed: 1993-06-07
Abstract: In numerical controllers, two-stage interpolations are undertaken to convert a curve path into desired values. In the first stage, coarse interpolation, track points are determined between which intermediate points are laid down in the second stage, fine interpolation. In a normal linear fine interpolation there thus results a chord path having deviations from the ideal contour and kinks. The invention describes a method for fine interpolation which firstly reduces kinks and thus enables smooth courses of the initial values but also enables an improved approximation to the ideal course with a few simple process steps. <IMAGE>

Title: Magnetometer
Inventor: ROUSE GORDON F
IPC: G11B5/39
Filed: 1993-12-21
Abstract: A magnetometer (10) having switched magnetisation and operated in a closed loop is specified, which has a magnetic-field resistor bridge (12) for detecting external magnetic fields. The output signal from the bridge circuit (12) to an amplifier (52) is magnetically zeroed by a feedback coil (62). Each of the bridge elements (14) has an easy magnetic axis which is magnetically and periodically switched over by a resetting coil (68). The output of the amplifier (52) is fed to an analog switch (54) and to an integrator (56), it also being possible for the sequence to be reversed. The output of the analog switch or of the integrator can be fed to a sampling and storage device (64) or to another sampling device which alternatively samples the signal output to it synchronously with the signal of the resetting coil. The output signal is processed by a low-pass amplifier (66). A clock generator (70) delivers signals to the resetting coil (68), to the analog switch (54) and to the sampling and storage device (64) (Figure 1). <IMAGE>

Title: Pusher-type propeller drive for aircraft, land vehicles or water craft
Inventor: KUSTERMANN FRANZ DIPL ING
IPC: B64C11/00
Filed: 1994-01-12
Abstract: It is known for interference to be used to influence sound emissions.   The invention makes available a pusher-type propeller drive in the case of which the exhaust pipes of the driving piston engine end in front of the propeller so that the sound emission produced by the propeller is influenced. The propeller is positioned on the drive shaft such that the sound emissions influence one another by interference and are in consequence reduced. The ends of the exhaust pipes and the plane of the propeller are sheathed by an annular casing which is constructed such that it has a sound absorbing effect and thus produces a further reduction in the sound absorption. A considerable reduction in the sound emission results from the interaction between interference and absorption.
