Title: Light velocity measurement apparatus - employs balanced rotating mirror fitted with prism for deviating returned beam and uses laser as light source (SW210676)
Inventor: HAGNER RICHARD DR
IPC: G01J7/00
Filed: 1975-06-04
Abstract: The Foucault method for measuring speed of light uses a mirror rotating at high speed. A fixed prism or mirrors deviate the returned beam of light eliminating use of an unbalanced and therefore dangerous rotating mirror. Light (9) from a laser source (1) strikes a high speed rotating mirror (2) and is directed through a converging lens (5) and via a mirror (6) onto a second mirror (7) at the focus of the lens. Reflected light (10) returning towards the rotating mirror is deviated by a prism (8) which receives all light directed to the upper part of the mirror (2). Deviated light is directed onto a ground glass screen enabling observation of change in angle of light from the mirror rest position to the rotating position thus enabling measurement of speed of light.

Patent DE-2537496-A1 (DE)
Title: Stoneware prodn. from ceramic compsn. contg. quartz porphyry - reinforced by acicular mullite crystallisation promoted by slow cooling
Inventor: KRUEGER GUENTER ING GRAD
IPC: C04B33/16
Filed: 1975-08-22
Abstract: The ceramic compsn. contg. a plasticity-diminishing natural stone component is improved by using as the latter a natural quartz porphyry contg. (in%) SiO2 60-80 (70-80) Al2O3 5-25 (10-15), Na2O 0-10 (0-1), and K2O 0-14 (7-9). The material phase compsn. comprises (in %): orthoclase 25-50 (33-38), quartz 25-55 (30-48), and muscovite 5-30 (10-20). Whisker-reinforcement of the product is promoted by the acicular mullite crystallisation effected by controlled cooling of the orthoclase-rich melt. In particular, the cooling rate from 1200-750 degrees C is decreased to 0.2 degrees C/min.; then, down to 280 degrees C, the cooling is 0.8 degrees C/min.; the final cooling to 20 degrees C is again very slow (0.2 degrees C/min.). The strength of the products is greatly increased. This is partly due to high compressive stresses arising in the material after the firing. The strength loss by a long-time exposure to moisture is decreased, because the moisture access to the ceramic material is hampered by the pressure-stressed glaze.

Title: Radio remote control system for moving objects - continues to operate through short failures of synchronising pulses
Inventor: DRIESNER JOERN DIPL ING
IPC: G08C15/12
Filed: 1975-10-08
Abstract: The ratio remote control system, for moving objects such as cranes, locomotives etc., operates reliably even when a control unit briefly fails to receive a synchronising pulse from its central station. Different areas are served by their own central stations, which are connected by cable to to the main control centre. The main control centre transmits a periodic sequence of address signals. Each address signal refers to one central station. Each central station receives its address signal and generates a sync. signal which it transmits to memories in the control units in its locality. The memory in each control unit is re-synchronised on receipt of each sync. signal and its internal timing circuit takes over until the next sync. signal is received.

Title: IC engine inlet manifold heating system - has alternating cross flow cylinder head
Inventor: LANGE KARLHEINZ DR
IPC: F02M35/10
Filed: 1975-10-31
Abstract: Engine has a four cylinder inline arrangement with an alternating crown flow cylinder head. The two intake pipes belonging to the two centre cylinders join to make a single pipe. The two exhaust pipes belonging to the first and last cylinder are joined to a single pipe on the same cylinder head side. In a corresponding manner, on the opposite side of the cylinder head the exhaust pipes of the centre cylinders and the two end cylinders join to a single inlet and exhaust pipe. A heat exchange region is formed on each side where the exhaust and inlets cross each other. The inlets are fed from separate curburetters and the mixture is heated on its way to the respective cylinders by heat from the exhaust pipes. Advantage claimed is a faster warming up of the intake pipes and a decrease in harmful exhaust emission during the cold running phase.
