Patent DE-2062589-A1 (DE)
Inventor: CHRISTIANSEN HANS-MARTIN
IPC: G10L25/90
Filed: 1970-12-18
Abstract: The system determines the base frequency of a speech signal which has been filtered so that the base frequency is no longer present. The signal is delayed by several successive time intervals and each time delayed signal compared with the momentary value of the input signal. The delay interval of the first delayed signal to differ from the input signal by less than a given amount is used as the period of the required base frequency. - Pref. the system uses successive delay stages, the output of each of which is supplied in turn to a comparator (7) via switches (5), controlled by a clock generator (4). The comparator (7) is also coupled to the input (8) for the speech signal and causes a counter (6) indexed by the clock generator pulses to be halted when the difference between one of the delay stage outputs and the input signal is below a given threshold.

Patent DE-2158968-A1 (DE)
Title: Controlling injection machine - esp for cellular plastics by regulating differential pressure across actuating piston
Inventor: HERBST RICHARD
IPC: B29C44/42
Filed: 1971-11-27
Abstract: The parent paten describes an apparatus for regulating the injection rams of an injection moulding machine, esp. for cell-forming plastics, in which the back pressure, which is pref. hydraulic, acting upon the piston is regulated so that the difference between this pressure and the forward driving pressure, which is pref. that of a gas storage container, is maintained constant. Instead of measuring the gas pressure directly, the difference between this gas pressure and the force acting in reverse against the ram in the injection cylinder, i.e. the pressure of the injected material, is measured; this is pref. done by measuring the strain in the piston rod, connecting the ram and actuating piston, directly by means of a strain gauge mounted upon the piston rod, or by means of a spring incorporated in the rod. The reading is then used as a control parameter to regulate the flow of fluid onto the front face of the actuating piston driving it in a backward direction.
Patent DE-2209961-A1 (DE)
Title: Sterile storage of medical appts - using shrunk plastic envelopes
Inventor: FROER WERNER
IPC: A61L2/04
Filed: 1972-03-02
Abstract: Medical appts. esp. heads of turbine-driven dentistic drilling machines, are wrapped in a plastic sheath which is heated in such a manner that bacteria are killed and the sheath shrinks so the it surrounds the head tightly and hermetically. A tear filament can be incorporated into the plastic sheath to facilitate its removal. Alternatively, point apertures can be made by means of a hot needle. This method is simpler than prior art sterilisation methods and the risk of damaging the appts. is reduced.

Title: Converter vessel replacement system - with tiltable support ring with dowels and tie rods
IPC: C21C5/46
Filed: 1972-05-20
Abstract: A metallurgical converter vessel is replaced into the U-shaped pivoted support ring of the blow stand by moving it horizontally on a carriage until its two peripheral carrier rings surround the support ring. The latter is then swivelled to provide a statically determinate 3-point support. Additional tie rods are then tensioned to create a statically indeterminate support. The removal of a converter vessel for replacement by another proceeds in the reverse order.

Inventor: LYASS ABRAM M
IPC: B22C1/16
Filed: 1972-08-09
Abstract: Self-hardening casting compsn. for the mfr. of moulds and mould cores.

Title: Relaxation oscillator frequency accuracy improvement - uses generator of highly stable frequency to determine commutating threshold voltage
Inventor: DIETL RUDOLF
IPC: H03K5/02
Filed: 1973-08-23
Abstract: The process is intended for tariff determination in telephone systems, using universal clock pulse generators with counting facilities. The threshold voltage determining the change-over time of each relaxation oscillator is so changed by superposition of a synchronisation pulse train delivered by a highly stable generator, or derived from it by frequency division whose frequency coincides with the relaxation oscillator nominal frequency, that at first it is increased and then reduced. The amplitude of the threshold rise or fall determining the synchronisation range can be varied by changing the superposition resistor.

Title: Heavy load lifting system - transports column sections along gantry for securing in place in succession
Inventor: ROETTGEN GERD
IPC: B66C19/02
Filed: 1973-11-30
Abstract: The system is partic. for the erection of travelling portal cranes in shipyards and avoids the need for erection towers etc. The columns of the portal are divided into sections of equal height, and after the lowest section on each side, has been temporarily secured to the foundation and the travelling bogies attached to it, the gantry is placed over both with the remaining sections on top of it.

Title: Endless cord conveyor for cigarette cartons - cord travels alongside guides, return strand travels underneath conveying surface
Inventor: QUITTENBAUM PETER
IPC: B65G15/02
Filed: 1974-04-22
Abstract: The cigarette carton conveyor consists of a cord which is employed in the same manner as an endless belt conveyor. The cartons are carried between guides and are engaged by frictional contact with the cord, which is conveyed along a straight path between return sections, when the cord is guided around a curve by means of a set of idler pulleys rotating about a vertical axis. The cord then travels around a drive pulley rotating about a horizontal axis, so that the return strand then runs underneath the conveying surface, around a guide pulley, and returns parallel to the conveying strand, still under the conveying surface. The guides terminate at the return point. A branch device employs a lifting mechanism which raises a carton from the guides and lowers it onto adjacent guides.
