Title: Tunable dyestuff laser resonator - has reflection refracting grid with specified flank steepness of grid troughs
Inventor: POLZE SIEGFRIED
IPC: H01S3/086
Filed: 1976-04-29
Abstract: The tunable dye stuff laser resonator consists of at least one mirror and a reflection refracting grid. The grid troughs are of such flank steepness and depth in the direction at right angles to the division that these two parameters are continuously decreased from the beginning of the division to its end. The rotary axis of the grid is outside the intersection point of the resonator axis with the grid surface. Preferably the rotary axis of the grid is at one centre vertical of the grid, and at right angles to the same at the mean tuning wavelength of the laser. The effectiveness of grid for the polarisation direction is at its optimum orthogonally to the grid troughs.

Title: Speciality cheese with markings - in mould covered rind, with colour or contour contrast pattern
Inventor: SOERENSEN HENNING
IPC: A23C19/068
Filed: 1976-05-25
Abstract: Cheese is prepared so that the edible mould in its rind constitutes a visible marking or symbol. The mould-coloured part of the rind forms recessed or stepped contours and can be streaked with spices or herbs such as paprika, pepper, caraway seeds or nuts. This shows the cheese texture to a potential consumer and does not conceal it like a foil package. The new method is cheaper than using transparent boxes, yet can be used to indicate by a symbol the maker of the cheese.

Title: Sewage bar screen - with basket for collecting screened material and disposal after screen has been tipped
Inventor: REPPERT HERBERT
IPC: E02B8/02

Title: Circuit for direct measurement of capacitances - has capacitor and variable resistor which are connected to AC voltage source and to CRO
Inventor: BESSAI HORST J
IPC: G01R27/26
Filed: 1977-02-12
Abstract: With the knowledge of Lissajous figures, capacitance of a capacitor (C) can be read on the scale of a variable resistor (R). The measured capacitor (C) and the resistor (R) are in series with each other and with a sinusoidal voltage source. Voltage from the resistor (R) is applied to the Y deflection plates, and the voltage from the capacitor (C) to the X plates of the CRO. Equality between the voltages (Ux, Uy) can be achieved by varying the resistance (R). Then a circle can be seen on the CRO screen. In this case R=1/omega C and c=1/omega R.
