Patent DE-2819339-A1 (DE)
Title: Fine screening surface with attached supporting coarse screen - are produced separately, soldered locally and bonded under vacuum
Inventor: MOHAN ANAND
IPC: C25D1/08
Filed: 1978-05-03
Abstract: A very fine gauze surface is provided with a support such as a coarse supporting sieve. The fine gauze surface and the supporting body are produced separately. On one or both of the bodies, the supporting body or the fine gauze, a layer of soldering material is deposited galvanically. At the most this layer is as thick as the lands between the openings in the fine gauze material. The gauze and the supporting body are then pressed together, the layer of solder if not already fluid, is liquefied by heat and the bond is made when the solder sets. The layer of solder is applied galvanically with one face of the supporting sieve or of the fine gauze covered by the matrix in which it was formed, as it hangs in the bath. The layer of solder may be applied with the reverse face of the body covered by a layer of lacquer. The layer of solder is at most half as thick as the lands of the fine screen. The solder is applied to the fine screen only on separate surfaces smaller than those of the supporting screen with which it comes into contact, such as small round zones. The pressing together of the two screens for soldering is effected by arranging them between pressing details and applying a vacuum. A simpler method of providing a fine screen having a thicker supporting body above it, without filling the holes with solder, or the difficulties of electroformation in which lateral bridges can be set up and block parts of the fine gauze. The supporting body may be of a different metal from that of the fine gauze.

Title: Conical spring system energy absorber - has conical rings with friction reducing rollers pushed together axially for compression
Inventor: ROEHRS GUENTER DIPL ING
IPC: F16F1/34
Filed: 1978-05-19
Abstract: The energy store for machines and equipment absorbs mechanical energy to reduce shock and return a large proportion of the absorbed energy. Between the inner and outer ring of the circular conical springs are arranged, in an axial direction, rolling elements for reducing friction between the rings on power transmission. The friction losses are reduced by balls or rollers held in guiding cages between the spring conical rings. The rings are compressed inwards and the outside ring is expanded when axial force is exerted.

Title: Mechanically coupled motor to measure async. machine slip - uses slip-ring voltage to give slip between rotor and stator
Inventor: MARTENS GERHARD DR ING DR
IPC: G01R31/34
Filed: 1978-08-04
Abstract: The system measures the slip between the rotor and stator fields of a loaded asynchronous machine. The rotor of a slip-ring motor (4) is mechanically coupled to that of the asynchronous machine (3) and the stator windings are connected in parallel. The slip-ring motor is connected to the three-phase rectifier (5) which delivers and d.c. voltage corresponding to the actual slip value. A controller (7) uses this to regulate the motor speed. A small slipring motor is used since it only delivers the measuring voltage and is otherwise unloaded.

Title: Burglar alarm system for motor vehicle - uses logic coding and timing network controlling annunciator via sequence evaluation circuit
Inventor: RUFF HERBERT
IPC: B60R25/10
Filed: 1978-11-25
Abstract: A burglar alarm system for a motor vehicle has a number of gating circuits connected in series. The alarm signal is released in all imaginable types of attempts at stealing the vehicle. The switches can be triggered by the door switch or the ignition switch to affect an evaluation circuit which controls an alarm annunciator. It contains a timing network having no effect on the alarm when operated within a given period. The alarm annunciator is controlled without any delay via the evaluation circuit if the switch is actuated in an incorrect or incomplete sequence. The alarm triggering signals are derived, either from the output of the timer or via coupling elements. The signals to the alarm annunciator are directed via a gate controlled by the ignition switch.

Title: Well logging by neutron activation analysis - for determining fluid flow rate around a steel casing
Inventor: PAAP HANS JUERGEN
IPC: E21B47/10
Filed: 1978-12-08
Abstract: A method is claimed for determining the location and flow rate of fluids flowing horizontally past a steel well casing in a subterranean formation. The method comprises (a) irradiating the formation around the casing with fast neutrons for a predetermined time to neutron-activate elements in the casing and >=1 tracer element in the fluid; (b) detecting gamma-decay count-rate signals for the activated elements during >=3 separate time intervals; and (c) using the count-rate signals and time-interval values to calculate the flow rate of the fluid and the amts. of gamma radiation due to the elements in the casing and the tracer element(s). The method can be used to monitor lateral water flow for assessing the viability of secondary oil recovery operations and for planning the operations. The method compensates for the presence of Mn56 in the casing, which would otherwise interfere with the flow rate determn.

Title: Paper sample bending stiffness measurement - determines minimum length hanging over clamp on sloping surface
Inventor: SEEGER RICHARD DIPL ING
IPC: G01N3/20
Filed: 1979-03-27
Abstract: The method is for measuring the bending stiffness of a rectangular sample plate, esp. of paper, is simple accurate and practical and does not require preparation of the samples to a specific size or measurement value processing. The sample piece of paper (1) is placed on a sloping surface (2) with the top edge (7) parallel to a horizontal clamp (5). The upper part (9) of the paper is bent so as to hang freely over the clamp. The length of the paper protruding above the clamp position is progressively reduced until the paper returns to lie against the inclined surface. The paper length above the clamp is then a measure of the bending stiffness.
