Title: Filled level of vessels monitored by radiation pulses - through period defined by fall and rise of received signal caused by presence of vessel
Inventor: SCHIESSL HANS
IPC: G01F23/288
Filed: 1980-06-20
Abstract: Liq. level in vessels as they pass between a radioactive source emitting a low-dose beam and a receiver is monitored by summating the pulses received within a specific period and comparing the integrated total with a predetermined threshold value. The measurement period is defined from the graph of the pulse rate plotted against time as the vessel passes. Pref. the measurement period is defined as the time interval between two instants at which the pulse rate corresponds to a predetermined fraction of the pulse rate when no vessel is present. More specifically, a reduced time interval may be used, which elapses between those instants which lie between the first two time instants and are at a specific instant from them. The threshold levels may be of equal size and the time differences used for defining the reduced interval may also be of equal value. No separate of photoelectric cell or other device of notifying the presence of the vessel is required; the triggering of the measurement is a function of the direct presence of the vessel a as read by the pulses.

Title: Valve for hot-gas pipes
Inventor: BITZ WILHELM
IPC: F16K3/26
Filed: 1981-01-28
Abstract: A valve for shutting off pipes of large diameter in which, for example, helium is circulating at a temperature of over 900 DEG C, particularly in plants with a high-temperature nuclear reactor. It consists essentially of a displacer (2) which bears the valve seat (22) and is arranged within a pipe (1). The closing element (3) is in the form of a hollow cylinder and is provided with a corresponding contact surface (10). It is secured in axially displaceable fashion on an annular compensator (4), the other end of which is fixed relative to a jacket pipe (5). The movement of the closing element (3) is brought about by the expansion of the compensator under pressure, e.g. that from an accumulator (40). To prevent the valve seat (22) and the contact surface (10) from welding together, the seat and the contact surface can be cooled and, in the closed state, are separated from one another by a flexible diaphragm. <IMAGE>

Title: Device for influencing the rate of the pressure drop in a sphygmomanometer cuff
Inventor: BERGER KLAUS DIPL PHYS
IPC: A61B5/0235
Filed: 1981-07-31
Abstract: There is proposed a device for influencing the rate of the pressure drop in a sphygmomanometer cuff intended for measurement of the blood pressure by the Riva-Rocci method. The device comprises a valve (16) which is controllable by an electric motor (18) and which forms the adjustment member of an electronic controlling device (10) for generation of a selectable pressure drop characteristic. The valve and the electric motor which may be also coupled, if appropriate, to a gear (105), are fastened on a baseplate (101) at a specific mutual spacing. The motor shaft or drive shaft (106) projects freely through an opening (107) in the baseplate and is connected via a screw gear (106, 128) to one end of a spring element (123), the other end of which (124) is firmly connected to the baseplate via a spacer element (125). Between the spacer element and the screw gear an end of the valve cone (115) is in engagement with the spring element. The valve can be designed as a valve which is open or closed in the resting state. In a valve which is open in the resting state, a compression spring (120) ensures that the valve cone (115) is retracted from the valve opening (117) and acts upon the spring element via a pin (118) connected to the valve cone. <IMAGE>

Title: Valve arrangement for a piston pump
Inventor: ANDERS CHRISTIAN
IPC: F04B53/10
Filed: 1982-03-11
Abstract: The invention relates to a valve arrangement for a piston pump, especially a horizontal in-line piston pump, with one or more intake and pressure valves, which are arranged in a valve cartridge. To facilitate assembly this valve cartridge is inserted in a recess or the like of the valve body. If valve cartridges of this type are used in horizontal in-line piston pumps, the valve spring force of the valves has to date had to be intensified owing to the friction effect of the horizontal valve axis, as a result of which the NPSH value of the pump was increased considerably. Piston pumps of this design had therefore to be operated mainly at inlet pressure. It is therefore proposed according to the invention that the valve body loaded by static pressure have an essentially horizontally aligned recess, preferably a bore, in which the valve cartridge loaded under rising pressure is arranged. The axes of intake and pressure valve are arranged essentially vertically in the valve cartridge, which can be inserted through a lateral opening into the said recess of the valve body. <IMAGE>

Title: Method for aligning the magnetic axis to the geometric axis of bar magnets
Inventor: WULLKOPF HELLMUTH DR ING
IPC: H01F7/02
Filed: 1982-05-03
Abstract: The invention relates to a method for aligning the magnetic axis of a cylindrical or cubic bar magnet to its geometric axis, in which method in each case at least one ferromagnetic pole piece is pushed or rotated so far on the pole surface or surfaces of the bar magnet that the magnetic axis lies on the geometric axis. Furthermore, the invention relates to a cylindrical bar magnet having means for aligning the magnetic axis to the geometric axis, at least one ferromagnetic pole piece with a smaller outline than the bar magnet pole surface being inserted such that it can be displaced radially in a pot consisting of material which cannot be magnetised and is inverted over the end or ends of the bar magnet. Alternatively, two pole pieces, having contact surfaces running obliquely with respect to the axis of the bar magnet, are placed one on top of the other on the pole surface of the bar magnet such that they can rotate with respect to one another and with respect to the pole surface.

Title: Slide calliper
Inventor: SCHANK HELMUT
IPC: G01B5/06
Filed: 1982-05-03
Abstract: The slide calliper, which serves in particular for directly reading off the friction lining thickness of brake linings of disc brakes, consists of a scale bar (1) and a measuring rod arrangement (2), having a graduation (18), that can be displaced on the scale bar (1) in the longitudinal direction of the slide calliper. A slide (3) on which a further graduation (17) is constructed is guided on the scale bar (1). After the zero mark of the graduation (17) has been set on the graduation (18) to the mark which corresponds to the lining anchor plate thickness, the friction lining thickness still present can be read off directly from the graduation (17) of the slide (3) after measurement has been performed. The distance between the two measuring surfaces (9, 10) corresponds completely to the thickness of the brake lining. <IMAGE>

Title: Device for converting a frequency, proportional to a measurement variable, of an electric measurement pulse into a quantity which can be represented as a quasi-analog quantity.
Inventor: ELTERMANN DIETMAR
IPC: G01P3/489
Filed: 1982-07-27
Abstract: This device is particularly suitable for displaying a pulse frequency of a distance pulse transmitter which is proportional to the speed of a motor vehicle. The device has two resettable measurement value counters which are constructed as period counters and successively form counts which are produced by counting out the period of the measuring pulse by means of clock pulses which can be switched step by step. For this purpose, the period counters are controlled by control means so that during the counting, in a measuring period using one period counter, the measurement value formed in the preceding measuring period is read out from the second period counter and conversely. In accordance with these period values counted out, step display values reciprocal to these period values, which are converted into addresses, are taken from a read-only memory and fed into a display memory. From there, they determine a rotation of the stepping motor corresponding to the step display value, to which sign-weighted motor control pulses are applied. The clock pulse frequency is halved step by step with increasing period of the measuring pulse in order to keep the memory content of the read-only memory low inspite of a fine resolution of the step display values. <IMAGE>
