Patent DE-2045347-A1 (DE)
IPC: G10L25/90
Filed: 1970-09-14
Abstract: 1,266,268. Excitation frequency detector. INTERNATIONAL BUSINESS MACHINES CORP. 4 Sept., 1970 [16 Sept., 1969], No. 42419/70. Heading H4R.  In a method of recovering the fundamental frequency of an input signal, e.g. for determination of the pitch frequency of a speech signal, a frequency detector produces a signal whose frequency is either the fundamental frequency "f" or the nth harmonic. In response to the detector output signal a frequency f/n is generated, modulated by the input signal and the presence of frequency components below a predetermined frequency in the modulated frequency are detected. If such components are present the output f/n is selected as the fundamental frequency while if such components are not present the output of the frequency detector is selected as the fundamental frequency. It is shown that if the output of the detector f is the nth harmonic of the input signal fundamental frequency then modulation of the input signal by the frequency f/n produces a D.C. component while if the output of the detector is the true fundamental frequency no D.C. component is produced by the modulation. As described the detector D produces a signal of frequency f which may be the fundamental or second harmonic of an input signal. Generators G1 and G2 produce quadrature signals at the frequency f/2 which modulate the input signal E in modulators M1 and M2. The D.C. or very low frequency components are detected by low pass filters and full wave rectifiers LPF1 and LPF2  and R1 and R2, the signals combined and a threshold device C operated to connect the output of a monostable Mcp to the output S if the D.C. component is detected and the output of detector D to the output S if the D.C. component is not detected. Use of two generators in quadrature prevents an erroneous result if the f/n signal generated by a generator is exactly in quadrature with the input signal fundamental.

Title: Die casting mould ejector - with automatic locking mechanism
IPC: B22D17/22
Filed: 1972-04-19
Abstract: The ejection device for castings from injection die casting moulds consists of a pushrod projecting into the die with an ejection plate. At its other end it has a cylindrical hole with a spring loaded inserted against which is pressed a coaxial outer push rod with a circular circumferential groove on which rides a radially expanding stop, which can partially expand into a circular groove of the guide sleeve bore through a slot in the push rod, thereby acting as both stop and lock in the outward retractive direction and rest position, but being free to move forward as the result of the forward edge of the groove being tapered. The design ensures, that the ejection plate is locked when it is in its non-operative position.

Title: Magnetic tape guidance mechanism - is used in tape recorders driving tape simultaneously from two capstans and with reversal
Inventor: RICHT OSKAR HUBERT
IPC: G11B15/44
Filed: 1973-06-04
Abstract: In instruments using magnetic tape where the direction of movement of the tape can be reversed, it is essential that the tape guidance mechanism is such that it operates differently in opposite directions. Movable tape guides are used based on the same axis as the pressure rollers, which operate when the tape is being fed to a spool, but are out of action when the tape is fed from the spool. Pref. the tape guide is in the form of a U-stirrup fitted over the pressure roller, with its arms pressing against both sides of the roller under elasticity. On both sides of the pressure rollers steel friction discs may be arranged.

Title: Identification of speech sound signals - has number of sample levels below threshold counted
Inventor: BALZEREIT CLAUS
IPC: G10L25/93
Filed: 1973-07-06
Abstract: The method is for the evaluation of a speech signal in which a voiced sound is distinguished from an unvoiced one by the appearance of a minimum of less than a predetermined threshold value which is recognised as a difference voltage between the input signal and individual sampled signals, in which the certainty of the differentiation is improved by taking a number of difference voltages exceeding twenty for comparison with the threshold level, the number falling below the threshold being counted and the required number for acceptance as an unvoiced sound being determined according to the degree of accuracy required.

Title: Microstrip arrangement for diode mounts - involves ceramic washer used between pair of series connected diodes
Inventor: HENZE WINFRIED
IPC: H01L25/03
Filed: 1973-09-28
Abstract: Two diodes are mounted in series between a microstrip and the ground plane, e.g. to provide greater power handling capability for varactor diodes. A contact prong on the underside of the top diode locates into a terminal pedestal tapped into a contact washer. The lower diode has its upper contact face in contact with this, the lower prong contact being gripped in a ground return a screw clamp in a tapped hole in the ground plane. Between the central terminal pedestal connecting the two diodes in series, there is a ceramic washer extending radially from the pedestable to the side walls of the ground plane boring. This forms a parallel heat sink, removing heat from the common junction area.

Abstract: The ceramic, single-layer capacitor is of any arbitrary configuration, such as rectangular, quadratic, circular, conical etc. On the two parallel main surfaces are provided metallisations which reach up to the edges of these surfaces. Each surface is provided with a creeping path strip from one edge to the other, which divides the metallised surface in at least two parts, while the creep path strips on the opposite surface intersect at any arbitrary angle. Each partial section on one main surface is connected with a partial section on the opposite main surface via an auxiliary surface. The creeping path strip run in straight lines at a small intersection angle, resulting in four segments in the ideal projection of both main surfaces.

Title: Dry process for chip and fibre boards - reducing press times and avoiding stress between inner and outer zones
Inventor: VOELSKOW PETER
IPC: B27N3/20
Filed: 1973-11-08
Abstract: Chip and fibre boards of milled timber, bagasse, straw, etc., are produced on a hot press with a continuously working densifying and preheating press feeding forward a mass of dry chips of fibres mixed with adhesives containing no hardener. The preheating press raises the temp. of the mass to 70-90 degrees C, the surfaces being then wetted with a dilute acid or base salt soln. vaporising during the hot pressing which is effected so quickly that the temp. at the board centre hardly exceeds 100 degrees C. As no hardener is present, preheating is facilitated; hot pressing time is therefore the shortest possible, and there is no vapour press. to cause lamination.
