Title: Circuit board for electric component connection - has small holes in metallised layer, in which component leads are clamped without soldering
Inventor: KOERNER GERNOT DIPL ING
IPC: H01R12/58
Filed: 1978-09-23
Abstract: The circuit board is built of separate layers. A top outer layer is made of a thicker material and carries a metal coating (2) on its underside. A bottom outer layer also consists of a thick material. The layers are perforated in a specified grid pattern (of e.g. 2.54 mm), but not the metal coating. When the conducting pattern is etched from the metallisation, connecting eyelets are produced at corresp. points. Their dia. is smaller than that of the holes in the layer material. Leads of the components are clamped in them without soldering.

Title: Visual particle length measurement - using video system with reference pattern of adjustable width superimposed on displayed particle
Inventor: MATSUMOTO TAMOTSU
IPC: G01B11/02
Filed: 1978-10-11
Abstract: A method of measuring horizontal particle length for particle size distribution analysis using a video monitor system and image analyser and a device enabling reproduction of a selected horizontal length in the analyser give the operator an intuitive horizontal length reference. This facilitates accurate, rapid, and efficient measurement. A strip pattern formed on the screen with a width corresp. to the desired horizontal length is moved horizontally so as to be superimposed on the particle and enable a visual length measurement to take place. For reproduction of the selected length a masking device marks out particles longer than the selected length. An adjustment pulse signal generated from the outputs of a pulse generator and the masker is used to set the pattern width.

Title: Automatic gain controller for radio receiver - constructed as integrated circuit without large coupling capacitor
Inventor: TANAKA KOUICHI
IPC: H03G3/20
Filed: 1979-10-08
Abstract: The modification to an automatic gain control circuit for a radio receiver is intended to make it more compact by eliminating the need for large capacitors, and by constructing the controller as an integrated circuit. The amplifier (11) output (17,OUT) is also applied to two circuits (41,42) with different reference levels. The first circuit (41) operates with an alternating voltage the second (42) produces a potential above its reference level determined by the charge and discharge rate of a capacitor. The voltages produced by the two circuits are designed to overlap. The overlap is detected in a further circuit (43) which produces an output pulse whose length is proportional to the overlap time. This pulse is integrated (44) and applied to the amplifier input as a gain control signal (GC).

Title: Oil and water separator having two successive chambers - each with light liq. layer at surface and wide interconnecting duct giving slow movement and self regulation
Inventor: HAMMERSCHMITT NIKOLAUS
IPC: B01D17/02
Filed: 1980-06-23
Abstract: A method of continuously separating components of a liq. mixt. having different densities, esp. sepg. oil or petroleum from water, uses an inlet chamber for the mixt. and an open-bottomed sepg. chamber penetrating into and below the surface level of the heavier liq. A substantially constant level of the heavy liq. is maintained by the heavy liq. outlet, and by regulating the inlet and discharge rates. The mixt. entering passes through a floating layer of the lighter liq. and in the lower region of the sepg. chamber additional sepn. and settlement takes place of the lighter liq.; from this sepg. chamber liq. passes beneath a comparatively still sepg. chamber before it reaches the downpipe leading to the heavy liq. outlet. Both the chambers have light liq. outlets above the heavy liq. outlet level. Pref., a preliminary separator is mounted upstream of the first chamber particularly for the sepg. out of sludge. The sepg. procedure is largely self-regulating and considerably simpler than in previous arrangements. A sepn. efficiency of greater than 97% is achieved.
