Patent DE-2541177-A1 (DE)
Title: Sea going hovercraft with support wings - has elastic trailing edges to reduce vibration and damage from wave tops
Inventor: JOERG GUENTHER
IPC: B60V1/22
Filed: 1975-09-16
Abstract: The sea going hovercraft operates as a surface skimmer by trapping a chsion of air under its profiled wings (1, 2) limitted by vertical walls (3) at the wing tips. The tailing edges of the wings are fitted with elastic strips (7, 8) which absorb vibrations, especially from the wave tops. This provides a smoother ride, acting as a type of dampening. Damage to the wing edges is reduced and a closer positioning of the trailing edges can be achieved, for an improved cushion. The elastic edges can be segmented and are reinforced by flexible metal inserts.

Title: Toy of several stackable cups - has sectioned pictures on outer surface, and contains pots for making sand castles
Inventor: LEHMEYER JOACHIM
IPC: A63H33/32
Filed: 1975-09-30
Abstract: The child's toy consists of three cylindrical cups (1a, 1b, 1c) each having the same dimensions, and a capping piece (2). On the outer surface of one cup (1a) is drawn a picture of a child's legs, a second cup (1b) shows its body and a third (1c) the head, so that the whole child is assembled by stacking the cups in a tower.

These interior pieces can be used for forming sand castles as can the cup itself and the had shaped cap. The toy gives the child a number of play possibilities, from stacking into a tower to making sand castles. Also, when more than one picture is drawn on the outer surface, by stacking the cups in the correct order and in the correct positions, several pictures can be produced.

Title: Gas or fluid particle analysis using light-scattering - has laser source with opto-acoustic filter and transient recorder for particle identification
Inventor: HOLLAENDER WERNER
IPC: G01J3/28
Filed: 1975-10-04
Abstract: The apparatus for the analysis of particles in fluids or air uses the light-scattering principle. The light source used is a gas-ionisation laser. The secondary radiation emitted by the particles illuminated by the laser beam is passed through an optical system to a continuously-variable acoustic-optical filter. The output of the filter is connected to a photo-multiplier. The electronically scanned output is in a narrow band of wavelengths and each time-point in the scanning cycle corresponds to a definite wavelength of the secondary emission. The photo-multiplier signal at a certain time-point is proportional to the intensity of the secondary emission at that wavelength. A transient recorder stores this information for the electronic processor for identification of the particles.

Title: Safety shut off valve for twinned steam lines in nuclear power plant - has slide which closes only one line leaving other open
Inventor: BERNDT LUTZ ING GRAD
IPC: F16K11/065
Filed: 1975-11-28
Abstract: A single valve housing contains a slide valve comprising two elongated holes, so arranged that, when one of the steam lines is closed by the valve, the other remains open and vice-versa. In this addition, the slide valve comprises no elongated holes and is a solid plate, sufficiently short not to penetrate into either of the steam lines in the position in which both these lines are open. Used for the interlocked shut-off of duplicated steam lines inside a nuclear reactor containment. No steam pressure can build up in the steam generator. The construction of the valve and its casing is considerably simplified; the length of the slide is reduced by at least twice the diameter of a steam line, and the casing requires virtually no extension beyond the outer side of each steam line.

Title: Solar energy converter using magnetohydrodynamic process - employing water as the operating fluid
Inventor: RADEBOLD REINHART DIPL PHYS DR
IPC: H02K44/08

Title: Ultrasonic measurement evaluation system - compares logarithmic digital amplitude signals from each ultrasonic detector with two limit values
Inventor: MOELLER PETER DIPL ING DR ING
IPC: G01N29/48
Filed: 1976-05-28
Abstract: The evaluation system for signals derived from ultrasonic measurements consists of a comparator (1) in which the logarithmic digital amplitude signals from each ultrasonic detector are compared with two limit values (GAC, GAD). The signals pass to a subtraction unit (3) fed with reference levels held in a store (2). The amplitude-difference signals are then passed to the comparator. For monitoring the reference amplitude, a second register (6) holds the amplitude values of a test sample, having the same time-slot addresses, in the form of a further reference signal. These reference signals are called up by the subtraction unit which then provides a difference signal from the two references. This signal (USDR) is then compared with the two pre-determined limit values. A programmar (4) controls the complete sequence.
