Patent DE-2208050-A1 (DE)
IPC: G10L19/02
Filed: 1972-02-21
Abstract: 1344019 Vocoder excitation generator INTERNATIONAL BUSINESS MACHINES CORP 27 Jan 1972 [25 Feb 1971] 3793/72 Heading H4R  In a speech synthesizer in which a low frequency portion of the speech spectrum is transmitted and distorted to derive an excitation signal for synthesis of a higher frequency portion of the speech spectrum, zero crossings of the waveform in a particular direction are detected and pulses generated, each of which represents by its amplitude or duration the time interval between a pair of successive zero crossings. In an analogue embodiment positive going zero crossings of the low frequency portion of the speech cause triggering of a sawtooth generator tile output from which is differentiated to provide pulses, generated during the flyback period, of constant amplitude whose width is dependent on the excitation frequency. In an alternative embodiment, Fig. 4(a), operating digitally, the sign of the low frequency band of the speech signal is fed to an exclusive or gate XOR both direct and via a one clock pulse delay T1 to derive pulses on each of the zero crossings. Combination with the original signal, SIGN, in AND1 provides pulses only on positive going zero crossings which are used after a delay T2 to reset a counter CO, which provides a staircase signal on its output. The undelayed pulse is used to sample the staircase just before resetting so that the output S is a pulse whose amplitude is dependent on the time elapsed since the previous resetting, and hence the excitation frequency.

Title: Bobbin packing - using a grooved collection plate for sorting with suction unit to carry a load
IPC: B65H67/06
Filed: 1972-06-05
Abstract: A push cylinder arrangement is used to load the collection plate with a counted batch of cross-wound bobbins, having been fed by a conveyor system. The grooves of the collection plate match the dias. of the bobbins to arrange them in firm and orderly ranks. When the collection plate is full, a suction unit descends to carry a load to an open container in a packing movement. The purpose is to simplify sorting, without damage to the bobbins, or allowing them to fall.

Title: Microwave vulcanising or polymerising upholstery - ensures heating of liquid reagents only, not mould thus reducing wastage of heat and time
Inventor: BERGWEILER KARL
IPC: B68G7/00
Filed: 1972-09-09
Abstract: A method of making upholstery articles of any shape, optionally comprising reinforcing elements and integral outer covers, from soft foam or natural or synthetic fibres, consists of using microwaves of regulated frequency and duration to generate the heat needed for foaming, hardening, vulcanising and/or polymerising. either the mould (itself of dielectric plastic) is passed along a tunnel through oscillating microwave fields, or a metal outer casing of the mould is temporarily connected to the energy source. In either case, control elements for frequency, energy and duration may be incorporated in the mould.

Patent DE-2359013-A1 (DE)
Title: Piston/cylinder assembly - has carrier block attached to either end of piston by wire running over pulleys
Inventor: WEHLING FRITZ
IPC: F15B15/08
Filed: 1973-11-27
Abstract: The arrangement is used to produce reciprocating translatory movement by means of a piston to and fro under hydraulic or pneumatic power. Previous arrangements tended to be bulky and required considerable space for operation because the piston rods protruded from the cylinder end at their extreme terminal point. With long strokes the rods had to be sufficiently dimensioned to prevent sagging, which again resulted in excessive weights. The present arrangements overall length is only somewhat in excess of the overall length of the stroke and the problem of a possible sagging of the piston rod is eliminated.

Title: Continuous chipboard mfg. process - has a controlled pressure length after high-pressure zone to prevent expansion
Inventor: BRINKMANN HEINZ
IPC: B27N3/24

Title: Non-servo hydraulic brakes for bus - with transmission brake to reinforce wheel brakes and operate as pump
Inventor: KLAUE HERMANN DR ING
IPC: B60T1/06
Filed: 1974-04-08
Abstract: The hydraulic braking system operates directly on the self adjusting wheel brakes, which are full discs. After a set brake pressure is reached the line to the wheel brakes is closed off while the transmission brake is applied. At the same time the transmission brake operates as a pump to provide hydraulic brake pressure for the wheel brakes. The system then acts as a self contained servo braking system, with full control from gentle, manual braking, to full servo controlled braking. No separate servo system is required, even for large vehicles.
