Title: Flowmeter for very small flows - rotates plate in field of coil, damping it at times so that oscillator operation stop
Inventor: KUEPPERS KARL DIPL ING
IPC: G01F1/075
Filed: 1976-04-14
Abstract: The flowmeter delivers an output signal depending on the flow. It consists of a vane wheel in a housing chamber, operated tangentially by the flow. The vane wheel drives a movable element of an electric signal generator. The medium whose flow is to be measured operates the vane wheel (4) by a jet from a narrow nozzle (5). The housing chamber is surrounded by a coil (7), part of an oscillator (9) oscillating circuit. It generates in the chamber (6) an alternating magnetic field perpendicular to a plane passing through the vane wheel (4) axis. The movable element of the signal generator is a small metal plate or a short-circuiting winding (10) on the vane wheel (4). When the wheel rotates, this movable element is at times perpendicular and at times parallel to the coil (7) magnetic field. When the plate etc. is perpendicular to the magnetic field, oscillating circuit is so strongly damped, that oscillations periodically stop. They restart when the plate etc. nears its parallel position.

Title: Optical scanning of templates by television camera - to control burner movement in flame cutting, and increase cutting speeds
IPC: B23Q35/128
Filed: 1976-08-06
Abstract: A television camera tube, or similar device with spot scanning, is used as a scanning head for steering appts. along a prescribed line or edge, esp. a burner in flame cutting appts., using a circular scanning beam. Pref. a television camera tube uses a scanning beam deflected in a circle on which the scanning point is sepd. from a reference point; and the optical signals provide electrical pulses employed to control the burner movement. The axis of the deflected circle pref. remains on the line being scanned, e.g. on a drawing. The device is used e.g. where a metal part is being cut from a plate using optical scanning of an engineering drawing or master. The photocell normally employed in conventional appts. is replaced by the TV camera tube. This eliminates the inertia involved in the rotation of conventional scanner heads, so the usual time daley is avoided and higher scanning speeds are attainable, e.g. 12 m/min.

Abstract: Moulded article prodn. from a sintered hard metal comprises (a) forming a mixt. of binder metal- and metal carbide powder; (b) prepg. a volatile, easily vaporisable binder soln. of Et cellulose and tetrahydronaphthalene; (c) mixing soln. with powder mixt. and (d) compressing, pelletising or esp. extruding the mixt. to a suitable shape. The blank is heated in vacuo to a temp. above evaporation temp of tetrahydronaphthalene but below sinter temp. of blank, to remove the tetrahydronaphthalene. The blank is then sintered to a sintered hard metal. The binding soln. pref. contains 0.5% Et cellulose and 4% tetrahydronaphthalene by wt. powder mixt. Tetrahydronaphthalene and Et cellulose soln. is used as lubricant in powder metallurgy. Powders contg. WC, Co and new lubricant soln. can be stored for several months without loss of lubricant. The tetrahydronaphthalene can be expelled without leaving C residues. Sintered blanks have high, controlled quality. Furnaces are free from C contamination and can be used in further heating cycles. Replacement of previously used kerosene and vaseline by new lubricant compsn. yields desired plasticity for compressing the powder. No extra heating step is needed before compression. Cycle for removing lubricant, after compression for 48 hrs at 427 degrees C is effected at 93 degrees C for 4-10 hrs depending on blank size.

Title: Inductive loop system for road vehicle speed measurements - detects duration of inductance change as function of velocity of vehicle using road
Inventor: ANDREAS PETER DIPL ING
IPC: G01P3/50
Filed: 1976-10-26
Abstract: The speed-measuring system for road vehicles comprises an inductive loop (2) embedded in the road surface and driven from a HF generator (1). The loop is tuned to resonance by a capacitor (3). A vehicle in the vicinity of the loop causes a shift in the operating point of the curve and a change in the voltage amplitude at the input of a detector (5). The detector is followed by a non-linear amplifier (9) which amplifies low levels and attenuates higher levels and this is followed by a differentiating circuit (6). The output of the differentiating circuit passes to a threshold detector (7) and the output pulse length corresponds to the induction variation and hence the speed of the passing vehicle.

Patent DE-2707143-A1 (DE)
Inventor: BARTENBACH CHRISTIAN HERMANN
IPC: F21V7/00
Filed: 1977-02-18
Abstract: The ceiling luminaire has a reflector arrangement (3) having approximately 25 to 100 or more individual reflectors (2, 2a). The latter collect the light falling onto the reflector arrangement (3), and distribute it uniformly over the area (8) to be illuminated. In contrast to prior ceiling luminaires without an antiglare louvre, the viewer of the new ceiling luminaire no longer sees only a brightly luminous point, but a multiplicity of luminous points which is equal to the number of the individual reflectors, the luminous intensity of a luminous point being only a small fraction of the luminous intensity of the lamp. A glare effect is thereby avoided. <IMAGE>
