Title: A capture circuit for restoring the carrier from a qam-signal
Inventor: BOSHOLD KLAUS
IPC: H04L27/38
Filed: 1987-08-27
Granted: 1989-09-14
Abstract: The circuit is provided for the demodulation circuit of a digital radio system, consisting of a demodulator (D), a voltage-controlled oscillator (VCO) and a carrier signal control voltage generator (TR) with a level monitor (P) at its input and an error monitor (F) for the bit error rate at its output. It is designed to synchronise carrier recovery within the shortest possible time following signal interruption, e.g. due to fading. A memory circuit (SP) is disposed between the carrier signal control voltage generator (TR) and the voltage-controlled oscillator (VCO), which ensures that, when the signal returns, the VCO continues to oscillate at the frequency prevailing before the interruption. In the event of an expected interruption in signal transmission, indicated by a rise in the bit error rate above a defined threshold, the error monitor (F) initiates the disconnection of the memory circuit (SP) from the VCO input before the interruption occurs. A sweep generator (W) with a preceding delay circuit (V) connected between the error monitor (F) and the carrier signal control voltage generator (TR) ensures the locking function in any event e.g. in the event of frequency offset following a long interruption. <IMAGE>

Title: Flavour containing foodstuffs
Inventor: REIMERDES ERNST HARTMUT
IPC: A23C19/06
Filed: 1982-02-17
Granted: 1985-09-05
Abstract: The invention relates to a process for producing aroma-containing food products in which exogenously and/or endogenously formed enzyme complexes are separated from specific pure or mixed cultures of microorganisms, which develop certain characteristic flavoring and aromatizing agents. The enzyme complexes are subsequently added to an aqueous solution or suspension of a substrate. The isolated enzyme complexes are optionally concentrated or standardized beforehand under careful conditions. The mixture of the substrate and enzyme complexes subsequently undergoes biochemical rapid ripening under suitable conditions until the desired aromatizing and flavoring agent concentration is obtained. The biochemical rapid ripening is then terminated by substantial inactivation of the enzyme complexes. The ferment solution or suspension obtained and which contains the desired flavoring and aromatizing substances, can be added to basic food substances for aromatizing them.

Title: Improvements to sanding disks
Inventor: OSENBRUGGEN ANTHONY ALFRED VAN
IPC: B24D7/12
Filed: 1998-08-24
Granted: 1999-03-11
Abstract: Accessories for an angle grinder include a disposable rotary sanding disk having quite large shaped ventilating/viewing apertures, for use with a resilient backing plate also having shaped ventilating apertures. The apertures of one or both parts are shaped so that snagging of the apertures on projections from the work surface is minimized and to facilitate air flow across the work surface during use. This air flow helps in cooling the work and ejecting detritus, so minimising clogging effects. The ventilating apertures also facilitate viewing the work to be sanded through the spinning disk during the abrasion process, so that operator feedback is immediate. The holes also give the sanding disk more resilience so that a greater area comes in contact with the work and the disk wears more evenly over its abrasive surface.

Patent JP-S5544307-B2 (JP)
IPC: F25J3/04
Filed: 1978-03-20
Abstract: Liquid oxygen and/or liquid nitrogen are made by removing carbon dioxide and water vapor from air, compressing the purified air in a re-cycle compressor and dividing the purified compressed air into first and second streams. Part of the first stream is expanded in a first expander and the refrigeration produced is used to cool both the first and second streams in a first heat exchanger. On leaving the first heat exchanger, the second stream is expanded in a second expander and the refrigeration produced is used to liquify at least part of the remainder of the first stream. The liquid stream is expanded and introduced into a fractionation column from which liquid nitrogen and/or liquid oxygen can be withdrawn. Expanded air from the first and second expanders is returned to the re-cycle compressor although part of the expanded air from the second expander is preferably introduced into the fractionation column. The invention is particularly suited to installations producing in excess of 100 tons of liquid per day and, at this size, preferred designs offer an estimated 51/2 to 9% power savings over the known prior art.
Patent JP-H0377983-B2 (JP)
IPC: G03B17/50
Filed: 1984-03-01
Abstract: Apparatus for processing individual rolls of self-developing type transparency film. The apparatus includes a spool having a first post, to which the leaders of a length of photographically exposed film and a length of flexible sheet material are adapted to be attached, and a second post, to which only the leader of the film is to be attached. The spool is adapted to be rotated so as to wind upon the spool a laminate comprised of the film, the sheet material, and a layer of processing liquid sandwiched therebetween for a period of time sufficient to form a visible image in the laminate. After formation of such image, the laminate is unwound from the spool and the film stripped from the sheet material as they are being rewound into their original containers. The posts are constructed such that the leader of the sheet material will automatically become detached from the first post at the end of the unwinding of the laminate thereby allowing the sheet material to be returned completely to its container while the second post maintains its attachment to the film leader. Thus, when the film leader is manually detached from the second post, it is available for withdrawing the processed film from its container for subsequent cutting and mounting of the film's individual frames.
