Title: Ultrasonic flowmeter with temp. compensation - has evaluation circuit producing measurement signals by integration dependent on time different measurement circuit
Inventor: KOUNO MASARU DIPL ING
IPC: G01F1/66
Filed: 1979-11-22
Abstract: A flowmeter using inclined acoustic transducers (1a, 1b) alternately exchanging upstream and downstream signals has an evaluation circuit measuring differences in reciprocals of transition times and deriving corresp. flow speed. High accuracy measurements are achieved in small dia. pipes and for a large temp. range despite the temp. dependency of the angle of refraction of the medium. The evaluation circuit has an associated compensation device receiving the reciprocal transition time signals and controlling the evaluation circuit to maintain the sum of the reciprocal time signals or one of the reciprocal signals itself at a constant value. The evaluation circuit produces measurement signals by integration dependent on the output of a time difference measurement circuit receiving measured and delayed pulse signal inputs.

Filed: 1980-03-14
Abstract: The method of forming light emitting diodes with metallised LED chips on both sides includes first forming an LED disc and applying a thick metal layer on one side for mounting on a base layer. The disc can then be cut by two sets of saw cuts at right angles, extending down to the metal lyaer. This forms a rectangular grid of cuts so that the disc can be cut into strips. The metal layer can be to the metal base layer by soldering, adhesive connection or deposition. In an alternative system, the cuts can be made after parallel metal strips have been attached to one side. The line of chips attached to a metal strip can be used as a prefabricated element for a set of chips.

Title: Speed control for vehicles on roads with speed restrictions - is activated by roadside transmitters and has override and warning system in vehicle
Inventor: HOELTER HEINZ ING GRAD
IPC: B60K31/00
Filed: 1980-03-25
Abstract: The proposed control system is used to regulate the speed of vehicles in a restricted zone to the maximum permitted value without action by the driver. Roadside transmitters signal the start, end, and maximum speed of a restricted section of road. Sensors and actuators on the vehicle generate optical and audible signals to warn the driver. At the start of a restricted section, automatic speed control is introduced and the driver warned to let go of the accelerator pedal. At the end of a section the auto control is cancelled and the driver warned in order to take control again. In an emergency the driver can take control by hard acceleration or braking. This action also activates external warnings, for example automatic flashing of headlamps or pulsating operation of the horn, for the duration of the rapid speed change. Slow braking or slow steady running does not activate the alarms.
