Patent DE-3036503-A1 (DE)
Title: Sail-board with hydrodynamic lift - has rear shape concave to water with flattened front
Inventor: POTT RICHARD
IPC: B63B35/79
Filed: 1980-09-27
Abstract: The profile of the sailboard is contoured for min. drag, with a flat bow running to a concave stern (9), with tapering keels each side of the board, deepest at the rear. The front of the board rises out of the water while the double keels grip the water for added control. An air inlet duct (11) at the front of the keel profile allows an air curtain to be drawn in to reduce drag. The keels can be moulded as part of the board or can be fitted as an accessory.

Title: Valve timing adjuster for IC engine - has curved spacer piece between overhead camshaft and valve stem
Inventor: HENNING HERMANN DIPL ING
IPC: F01L1/34
Filed: 1980-11-06
Abstract: The engine has a valve (3) whose stem (4) is depressed against a spring (8,9) by a cam (6) on an overhead camshaft (5). There is a curved spacer piece (7) between the cam and the valve stem. The inner surface (14) of the piece is clear of the cam. A projection (15) on the inner surface extends to the cam base circle and forms the follower for the cam. The spacer piece is held on an arm (13) projecting from a sleeve round the camshaft. The sleeve is moved according to engine speed. This alters the position of the projection (15) and thus the time at which the cam lifts the valve.
Patent DE-3041965-A1 (DE)
Title: Magnetic therapy appts. with evenly spaced permanent magnets - cause abrupt changes in magnetic field with corresponding electric field peaks to stimulate nervous system
Inventor: TANAKA SHOICHI
IPC: A61N2/00
Filed: 1980-11-06
Abstract: The idea that a magnetic field can stimulate blood circulation is further developed by the prodn. of an uneven permanent magnetic field with regularly spaced peaks. This results in more efficient induction in the bloodstream passing through this field with resulting stimulation. Several permanent magnets (10) of similar polarity are evenly spaced, the spacing being related to the pulse waves which occur every second or so. As the pulse wave (9) along a blood vessel passes through the suddenly changing magnetic field (B) several electric current spikes (15) are induced. A further improvement is achieved by reversing the polarity of alternate magnets. The electric field peaks stimulate the nervous system.

Title: Method and arrangement for automatic detection of a communication signal
Inventor: HARDERS BODO DIPL ING
IPC: H04B1/10
Filed: 1982-03-26
Abstract: The invention relates to a method and an arrangement for automatic detection of a communication signal even when simultaneously affected by interference signals, where the autocorrelation function is formed from the combined signal. The value of the autocorrelation function is used as a criterion for determining whether a communication signal is contained in the combined signal or whether interference signals only are present, and furthermore the envelope is formed from a signal-interference combination and the autocorrelation function is derived therefrom. Particularly in the case of automatic radio monitoring systems, the use of the correlation analysis with the formation of the autocorrelation function for detection of a communication signal, at low cost compared with other methods, offers the advantage of clear and automatic distinction between communication and interference signals. Similarly, as is known, the speed of the evaluation is of major importance, and this is guaranteed by the invention in that delays in operational procedure as a result of superfluous monitoring of interference signals are avoided. Also with the prior formation of the envelope, a recorded signal or signal combination is supplied to the cross-correlator (4), on the one hand directly and on the other hand via a time delay (3). The autocorrelator (3, 4) forms the required autocorrelation function. A threshold switch (5) displays an existing communication signal when a permanently set threshold value is exceeded and, if required, prompts the searching receiver (1) to interrupt the search routine. <IMAGE>

Title: Crystalline alumosilicate, process for its production, and use
Inventor: BAACKE MICHAEL DIPL CHEM DR
IPC: C01B33/38
Filed: 1982-03-27
Abstract: Alumosilicate PZ2 has the chemical composition 0.05 +/- 0.03% Na2O, 1.40 +/- 0.6% Al2O3, 88.0 +/- 3.0% SiO2, 0.5 +/- 0.2% P2O5, 3.0 +/- 1.0% loss on ignition, and the X-ray diffraction diagram shown in Table 2. It can be prepared from alumosilicate PZ1 by treatment with dilute acids or by ion exchange with ammonium chloride followed by calcination. Crystalline alumosilicate PZ1 is prepared by effecting the crystallisation in the presence of an organic template compound of the formula R3P-(CH2)n-PR3X2. The synthesis mixture can have the composition SiO2/Al2O3 = 20-250, Na2O/SiO2 = 0.01-0.5, OH<->/SiO2 = 0.01-11.0, R/SiO2 = 0.01-0.2, and H2O/SiO2 = 10-40. The synthesis mixture is agitated at autogenous pressure at temperatures between 90 and 200 DEG C. The alumosilicate PZ1 is converted into alumosilicate PZ2 by treatment with dilute acids or with ammonium chloride, followed by calcination. This alumosilicate PZ2 can be used as a catalyst for the conversion of alcohols into hydrocarbons.
