Patent DE-1910356-B2 (DE)
Title: Parametric amplifier or mixer - has reactance diode and specified relationship between diode-, housing- and additional-capacitances
IPC: H03F7/04
Filed: 1969-02-28
Abstract: The parametric amplifier or mixer has the ratio of the sum of the housing's capacitance to the mean capacitance of the varactor diode lying between 0.5 and 1. The additional capacitance is obtained by increasing the diameter of the diode's holder. The circuit's dynamic Q is defined by specified equations in terms of the ratio of pump to signal frequency for a given capacitance ratio or the capacitance ratio is defined in terms of the frequency ratio for a given Q. These specified relationship optimise the device's gain-bandwidth product by effectively optimising the additional capacitance.

Title: Illuminated pushbutton display board - has array of pushbutton plungers to transmit light to display board to indicate availability of personnel
IPC: G09F7/00
Filed: 1969-03-08
Abstract: A display board for information uses an array of spring biased plungers of a transparent material that allow a manually selected optical display. Typicall the array of plungers (15) may be used on an information in a company to indicate the availability of personnel e.g. available (ANW), absen (ABW), available at a certain time (10) (12 etc.) The personnel names are located on the left hand side of the board (18) and relate to a specific row of plungers. Each plunger is cylindrical and is spring biased to project from the front panel (11). When pressed a sleeve on the plunger engages a retaining clip, and in this position transmits light from a source within the housing. The display appears as a combination of point illuminations.

Title: Motor driven swimming pool floor suction cleaner - has sensors and gears reversing appropriate wheel on encountering obstacle
IPC: E04H4/16
Filed: 1969-04-21
Abstract: Twodrive wheels, with electric motor drive, and two front corner sensors to effect swivelling movement on encountering obstacles, are incorporated in the machine for sucking dirt from the bottom of a swimming pool. Each sensor (90) isconnected to a driving wheel (64, 66) via a gear train. With a sensor activated by touching an obstacle, the direction of rotation of the wheel concerned is reversed for a set period thus checking forward movement of the machine. The sensors may be allotted to diagonally opposite wheels. This facilitates evenly distributed working over the pool bottom.

Abstract: A pressure sensor portion having a pressure-responsive element for detecting gas pressure in reference to the atmospheric pressure is connected to a mounting body such as a canister mounted on a vehicle by means of a fragile connecting member. The connecting member breaks off to dismount the sensor device from the mounting body when a high impact due to an accidental collision or crash is imposed on the sensor device, and thereby an inlet port connected to the sensor portion for introducing gas pressure thereinto is prevented from being broken or damaged by such a collision impact. The fragile connecting member may include a tubular pipe formed integrally with a cover that hermetically closes an inner cavity of the sensor portion. A mounting bracket connected to the sensor portion via the fragile connecting member may be used to mount the sensor device on the mounting body.

Patent JP-H0816514-B2 (JP)
IPC: F02M63/00
Filed: 1986-03-19
Abstract: A magnetic valve, in particular a fuel metering valve for fuel injection systems of internal combustion engines, is proposed which serves to measure the injection quantity and control the instant of injection. In a valve housing, the magnetic valve has an electromagnet and a valve closing element actuated thereby, which cooperates with a fixed valve seat. To damp the opening movement of the valve closing element against a fixed stop and to keep the hydraulic forces of adhesion between the valve closing element and the stop low, a damping chamber that is open toward the valve closing element is disposed on the stop. As the valve closing element approaches, fluid is positively displaced out of the damping chamber in the form of a squish flow between the stop face and the head element of the valve closing element, so that recoiling is avoided due to thus-generated damping. As the valve closing element lifts, fluid can flow through a throttle bore or a check valve into the damping chamber, so that release of the valve closing element from the stop face can be effected with little force being exerted.
