Abstract: In den Zeitpunkten der Nulldurchgänge (Polaritäts­
wechsel) einer alternierenden Spannung (z.B. einer sinus­
förmigen Wechselspannung) sollen Schaltvorgänge (z.B. 
die Umschaltung eines Polwenders) ausgeführt werden. Zu 
diesem Zweck wird die alternierende Spannung in einer 
Gleichrichterschaltung, die wenigstens einen Proportional­
verstärker (V1) und einen an dessen Ausgang angeschlos­
senes stromrichtungsabhängiges Schwellwertelement 
(Gleichrichterdiode G) enthält, einer Doppelweggleichrich­
tung unterworfen. An dem Verbindungspunkt zwischen dem 
Ausgang des Proportionalverstärkers und dem Schwell­
wertelement (G) ist wenigstens ein Komparator (K1) 
mit einem ersten Eingang angeschlossen. An den zweiten 
Eingang des Komparators (K1) ist eine Referenzspannung 
angelegt, deren Größe zumindest annähernd dem halben 
Wert der Schwellenspannung (us) des Schwellwertelemen­
tes (G) entspricht. Bei jedem Nulldurchgang der alternieren­

portionalverstärkers (V1) einen durch die Schwellenspan­
nung (us) des Schwellwertelementes (G) gegebenen Span­

Abstract: A motor vehicle suspension system comprises four hy­
dro-pneumatic struts (1, 2, 3, 4) three of which (1, 2, 3) are pro­
vided with sensors (33, 34, 35) to detect variations in length of 
the struts. A control system (39) is responsive to the sensors 
(33, 34, 35) and operates valves (40, 41, 42) to add fluid to or 
remove fluid from struts (1, 2, 3) to maintain the length of these 
struts constant. The pressure within the fourth strut (4) is con­
trolled so that the proportion of the static roll-torque (caused 
by off-centre loading of the vehicle) which is reacted by the 
front and rear axles is the same as the proportion of the static 
weight of the vehicle which is reacted by the front and rear ax­
les respectively. Control of the pressure within the fourth strut 
(4) is accomplished by a control valve (14) having a valve spool 
which is subject to the pressures within the four struts (1, 2, 3, 
4).

Abstract: A seat 3 for use in a vehicle simulator which seat includes 
at least one pneumatic cushion 5 and a bellows arrangement 9 
for controlling the pressure in the cushion, and thus the level of 
the top surface of the cushion. The bellows arrangement 9 and 
the cushion 5 together define a closed volume system. A pis­
ton and cylinder 15 is connected to a rod 17 which serves to 
expand or contract the bellows in accordance with signals 
generated by a controller 21 supplied to a servovalve 19 for the 
piston and cylinder 15. Typically, the seat 3 has four seat cush­
ions 5 and four back-rest cushions 5, each of which cushions 5 
has its own respective bellows pressure-control arrangement, 
whereby the top surface of any selected cushion may be 
caused to rise or fall, thereby feeding motion cues to a person 
sitting in the seat.

Title: Method of putting into operation the remote power supply to electricity consumers, and circuit arrangement for carrying out the method
IPC: H04B3/44
Filed: 1983-04-29
Abstract: For remote feed of a group of electrical users connected in series in a closed loop, a dc voltage is applied to the loop in a polarity opposite to a normal feed voltage in order to determine whether interruptions are present, even if a human body is shunting the loop at the interruption. Each of the users has a diode connected in parallel to its inputs which is polarized such that when the test voltage for creating a test current is applied, substantially only a resistance of the loop is measured exclusive of the users. A loop resistance is determined from a measurement of the test current and the loop resistance is compared to a test resistance set lower than a human body resistance. If the loop resistance is lower than the test resistance, then normal remote feed current is applied to the loop since no interruptions exist. If the loop resistance exclusive of the users is of a same magnitude or greater than the human body resistance, then shunt arms are employed in the loop comprised of resistors and diodes to lower the loop resistance during feed of test current so as to reliably detect whether an interrupt location is present.

IPC: H01J9/14
Filed: 1984-12-04
Abstract: Spherically convex microgrids may be prepared from a 
flat microgrid structure by using a process depending on the 
differential thermal expansion between the material of the 
flat structure and a layer of other material applied thereto. A 
flat process blank 2 is etched with grid apertures in a 
microgrid area to which a curvature is to be added during 
fabrication. The blank is then subject to the deposition of a 
thin layer 4 of aluminium nitride (or other differential thermal 
expansion material having a positive thermal expansion 
mismatch with the material of the microgrid substrate) over 
at least the microgrid area (Step A). The differential thermal 
expansion layer is coextensively with the grid area, so as to 
confine the warping substantially to the grid area where 
curvature is desired. Curvature (Step B) is accomplished by a 
controlled heat warping step in an inert atmosphere (for a 
silicon microgrid structure of 250 micrometers thickness, 
heating at 1200C to soften the silicon). Permanent deforma­
tion, occuring as a result of the differential thermal expan­
sion, is controlled by selection of temperature and time of 
heat treatment to achieve the desired curvature. The alumi­
nium nitride layer (Step C) is removed prior to cooling.

Title: Unloading device for bulk material
IPC: B65G65/48
Filed: 1987-04-10
Abstract: An unloading device at the bottom of a container for bulk material has at least one clearing arm which is supported around a pivoting axis at a distance from the centre axis of the container for bulk material and pivotably in parallel to the latter. This arrangement is designed in such a manner that when the clearing arm is rotated in the opposite direction to the operating direction of rotation, the clearing arm is pivoted around the pivoting axis in the direction towards the centre of the container for bulk material so that the outer end of the clearing arm, which is particularly heavily loaded and sensitive to wear, is accessible, for example, for maintenance purposes without having to empty the container for bulk material. As soon as the unloading device is again driven in the operating direction of rotation, the clearing arm and particularly its outer end automatically swing round the pivoting axis in the direction of the outside, that is to say in the direction of the inside wall of the container for bulk material, in which arrangement a stop, by means of which the clearing arm is fixed in its operating position, becomes effective in the final operating position. The clearing arm can be pivotably movable overall around the pivoting axis or the clearing arm can be designed in two parts, in which case only the outer part of the clearing arm is pivotable around a pivoting axis which is provided at the outer end of the outer part of the clearing arm which is rotationally rigidly connected to the drive. <IMAGE>
