Title: Regulating and shut-off device for flowing media, especially rotary cone valve
Inventor: GRUTESEN LOTHAR DIPL PHYS
IPC: F16K5/20
Filed: 1988-06-03
Abstract: Regulating and shut-off member for flowing media, especially a rotary cone valve, with a shut-off element which is designed as a segment (1) of a sphere and can be pivoted into a seat element (2) with a circular passage opening. In the closed condition, the centre (M) of the segment (1) lies on the centre line (m) of the passage opening of the seat element (2). The axis (D) of rotation of the pivoting movement lies in a plane (d) parallel to the seat plane containing the passage opening, at a predetermined distance (L) from the seat plane. To form an eccentric, the axis (D) of rotation is arranged offset by a predetermined distance (X) relative to the centre line (m) of the passage opening. In order to achieve jerk-free opening of the shut-off element (1), the centre (M) is displaced away from the passage opening in the closed position by an amount (B) relative to the plane (d) of the axis (D) of rotation such that the angle between the vector of motion of the shut-off element (1) and the normal vector of the contact surface between the shut-off element (1) and the seat element (2) is, at all points of the contact surface, greater than or equal to the rubbing angle for the mutually touching surfaces of the shut-off element (1) and the seat element (2). <IMAGE>

Title: Device for positioning a workpiece or an auxiliary device in two coordinates with high displacement resolution for NC milling machines
Inventor: KOENIG WOLFGANG DIPL ING
IPC: B23Q1/48
Filed: 1988-08-08
Abstract: In order to move a tool or an auxiliary device with high positioning accuracy and with fine displacement resolution in the direction of an axis and to rotate it simultaneously or subsequently about this axis, a compact and easy-to-assemble positioning device has been created, preferably for NC milling machines or machining centres, in which, according to the invention, the mounting plate (12) carrying the workpiece is moved by a threaded-spindle drive (7, 8) in the axial direction, and this threaded-spindle drive itself, connected to a rotary cylinder (2), is rotatably fitted in an outer housing (1) by the bearings (3, 4). By the selection of a threaded-spindle drive free of backlash and drive elements free of backlash, the directions of movement of the positioning device can be reversed without loss of accuracy. The possibility of exchanging a few parts, namely the outer housing (1), the threaded spindle (8) and the rotary cylinder (2), for a positioning task with longer axial travel and the possibility of exchanging the motors (15, 20) or if need be of attaching suitable reduction gearing for a finer displacement resolution bring about high flexibility of this positioning device for the most varied applications. <IMAGE>

Title: Method for controlling the degree of toasting in toasters
Inventor: SEYER REINHARD
IPC: G01N33/00
Filed: 1988-12-16
Abstract: The invention relates to a method for controlling the degree of toasting in toasters. It is known for the degree of toasting to be controlled as a function of the toasting time, the toasting temperature or of the coloration of the bread during the toasting process. By this means, different toasting results are achieved, depending on the type of bread and moisture. A method for controlling the degree of toasting, by means of which equivalent toasting results are achieved independently of the power supplied, the toasting temperature or the type of bread used, is made available by a sensor detecting the gases emerging from the bread surface during toasting and controlling the desired degree of toasting as a function of the concentration of an emerging gas or of an emerging gas mixture.
Patent DE-3905735-A1 (DE)
Title: Method for evaluating an input signal
Inventor: HENNING MANFRED
IPC: G01D1/02
Filed: 1989-02-24
Abstract: In a method for evaluating a time-variable and periodically pulsating input signal by generating a pulsation-free replacement signal, the latter is formed from the mean value of the input signal in time in the normal case. In the area of steady-state signal transitions, the replacement signal is temporarily formed from the input signal itself which allows a delay-free operating sequence to be achieved. The mean value is preferably formed by sampling and storing and processing a minimum of all signal samples of the input signal which have occurred at a particular time during one or more recent pulsation periods. A device used for carrying out the method is of simple construction and comprises a mean-value forming circuit, preferably one with timing and sampling of signal samples, a comparator for switching the evaluation in the regions of signal transition, and a change-over switch controlled thereby.

Title: Method for regulating the amount of air fed to a gas mask, and gas mask in which this method is used
Inventor: PONKALA JORMA
IPC: A62B18/00
Filed: 1989-03-13
Abstract: A method by which the amount of air fed to a gas mask is essentially kept constant by using the motor of a ventilator as sensor, by means of which the power of the motor is regulated. An electronic regulating circuit keeps the amount of air constant by regulating the pulse-width ratio of the voltage present at the motor. A light-emitting diode which is connected to the control circuit transmits a signal when the ventilator motor is incapable of producing the preselected amount of air. To prevent the battery from being discharged too much, a voltage-monitoring circuit interrupts the power supply of the arrangement when the fed voltage drops below a preset limit value.

Patent DE-3919680-A1 (DE)
Inventor: NETH ALOIS DIPL ING
IPC: H04J3/08
Filed: 1989-06-16
Abstract: In the transmission of digital signals in time-division multiplex via a transmission link with repeater stations at which time slots are either only dropped are also reoccupied, the problem arises of continuing to maintain the information transmission even with an alarm triggered in a repeater station. The invention provides for a bypass circuit (11) via which the repeater station is bypassed when an alarm is triggered in it. If a reoccupation of the time slots is intended, the bypass circuit (11) in this arrangement can send a message to the neighbouring repeater stations and/or the line terminating device for allowing the reallocation of time slots which have not been reoccupied in the repeater station. If the time-division multiplex signal contains a service channel, messages can be sent to the neighbouring repeater stations and follow-up measures initiated via this channel. <IMAGE>

Title: Open=end spinning rotor shaft - has axial elasticity at the free end towards the step bearing to dampen oscillation
Inventor: BUNGTER KARL
IPC: D01H4/12
Filed: 1990-03-23
Abstract: The open-end spinning rotor shaft, supported at the free end by a step bearing, has axial elasticity at the free shaft end near the step bearing. Material for the free shaft end has an elasticity coefft. which differs from the material in the remainder of the component. At the step bearing, the free shaft end can be fitted with at least one grooved cut with a depth through the centre line of the shaft, or at least two cut grooves are fitted on opposite sides of the shaft behind each other along the shaft line, or they are displaced from each other by the same rotary angle round the shaft circumference and equidistant along the shaft line. As seen from the end of the shaft, the cut grooves run at an angle of 90-45 deg. to the centre line, or at 45 deg. Alternatively, the cut groove starts at a given gap from the shaft end, and follows a spiral path with a given pitch along the axial line of the shaft for a set length. ADVANTAGE - The structure reduces oscillation and the wear effect on the bearing, to allow higher speeds and a longer life.
