Patent DE-2612676-A1 (DE)
Title: Goniometer for measuring tension and crystal orientation - in which sample performs three movements
Inventor: KRAUSE HANS PROF
IPC: G01N23/207
Filed: 1976-03-25
Abstract: Goniometer allows simultaneous measurement of tension and crystal orientation distribution in crystalline materials. The specimen performs three movements: theta rotation about the line normal to the measuring plane (Nm); at the same time the counter tube performs rotation about the same axis by 2 theta, whereby incident (IO) and reflecting (IR) radiation form the measuring plane. Theta movement is performed at a given angular interval. The other two movements are Alt. Phi movement about an axis (A-A') which passes through the measuring plane and the surface of the specimen; and movement about the line normal to the specimen. Alt. Phi and movements are performed stepwise. Pref. an X-ray goniometer is used.

Title: Adjustable towbar for single axled trailer - has parallel struts to ensure horizontal setting of coupling hook
Inventor: KERSTING FRANZ JOSEF
IPC: B60D1/46
Filed: 1976-04-09
Abstract: The towbar (3) of the single axled trailer is hinged at both ends about horizontal axes (2, 4) with the towing hook attached to a hinged coupling section at the front of the towbar. A second support strut (7) is set parallel to the towbar and forms the other side of a parallelogram which enables the towbar to be set at different angles to the horizontal without altering the angle of the towing hook. The coupling section is linked to the trailer by a telescoping strut (13) whose extension determines the tipping angle of the trailer. The strut enables the trailer attachments to be height adjusted without increasing the strain on the coupling hook.

Title: Four stroke engine with exhaust cylinder - in which arrangement allows residual pressure to be converted completely into output
Inventor: MICHALZIK GERHARD
IPC: F02B75/02
Filed: 1977-02-04
Abstract: The four stroke engine has an exhaust cylinder inserted between two engine cylinders. This exhaust cylinder has about twice the diameter as the engine cylinders. The outlet valves of the engine cylinders allow the exhaust gases to flow through the over-flow channel (U) alternately into the middle exhaust cylinder. Consequently the residual pressure is converted completely into output so that the action of conventional four-cylinder, four-stroke engine is achieved. In addition, petrol consumption is reduced by 40-45% and noise and exhaust is low.

Title: Laboratory pipe coupled gas flowmeter - counts bubbles as gas escapes below liq. surface by detecting sound made by each bubble
Inventor: WIENAND HANS ING GRAD
IPC: G01F1/00
Filed: 1977-06-15
Abstract: A method is used for the quantitative measurement of the flow of gas through a pipe, esp. for laboratory purposes, in which the gas passes through a dip-tube immersed below the level of liquid in a vessel, escaping in the form of a regular flow of bubbles of constant volume, which are counted to give a measure of the total flow.
