Title: Photocopier providing multi-copies - has separate sensors for original document and copy and fail=safe protection if original works loose from drum
IPC: G03B27/12
Filed: 1977-08-27
Abstract: The multi-copy photocopier has the document rotating with the process drum for every copy, and a copy separator to extract the finished copy. Separate sensors monitor the movement of the copy and the document and inhibit the repetitive cycle if the document does not remain on the drum. The system provides a rapid alarm if the document is loosened from the drum through static attraction to the copy. This prevents the valuable original document from being filed, punched, etc., with the copies.

Title: Telephone call holding and routing system for PBX - stores unsuccessful caller address and busy connection to identify originally occupied connecting link
Inventor: FEY DIETER DIPL ING
IPC: H04M3/54
Filed: 1978-08-30
Abstract: If the called subscriber number does not answer within a certain time and if the PBX is authorized for retransmission, a check is run on each of the remaining positions to ascertain if they are free or busy. The connection is then made to the free station. Identification of the originally occupied connecting link is carried out by storage of the address of the unsuccessful caller and the busy connection. If none of the other positions are free, the call remains with the original, non-answering position. If, however, one other position becomes free, this is given priority and the waiting caller is coupled to this position.

Title: Vehicle fuel consumption indicator - measures induction system pressure and produces acoustic warning when transducer output exceeds threshold voltage
Inventor: BECHTOLD HORST ING GRAD
IPC: G01F9/00
Filed: 1979-08-09
Abstract: The device displaying instantaneous fuel consumption, esp. for vehicles, measures the consumption from the underpressure in the engine induction system. A transducer converts reduced pressure variations into electrical voltage variations. It is used to generate an unambiguous accoustic signal when a given consumption rate is exceeded and, if required, when consumption falls below this rate. The transducer is connected to the induction manifold via a mechanical choke which excludes higher frequency pressure variations. The transducer output is compared with an adjustable threshold voltage by a comparator producing a voltage when the threshold is exceeded. The comparator output drives an accoustic signal generator. The transducer has an associated damping circuit which suppresses the higher frequency components of its output signal.

Title: Telephone exchange circuit connection with varying special facilities - allows access to higher facility exchange by subscribers in low facility area
Inventor: GYALISTRAS DIONYSIOS DR ING
IPC: H04Q3/00
Filed: 1979-09-13
Abstract: The object is to allow access by selected subscribers in a low facility, typically older, exchange area to a more modern high facility exchange. By high facility is understood, for example, multiple connection for conference conversations, individual call costing, and similar automatic facilities. The object is achieved by having concentrator circuits (Kc) at a low facility exchange (Vc) to which subscribers (Tc1,Tc3,Tc5) requiring enhanced facilities can be connected via the normal exchange equipment (Hc). The concentrator is then directly connected by a line to a high facility exchange (Vb). Other subscribers are connected to the standard connector and selector system (Wc) for outgoing calls. The older exchange thus needs only the addition of concentrator equipment (Kc) and no modification to existing selectors. The concentrator power supply is taken from the exchange in which it is installed.

Title: Fibrous webs for prodn. of moulded pressings - mounted between reinforcing sheets of inextensible material with arrays of slits
Inventor: KISS GUENTER H
IPC: B32B27/10
Filed: 1980-03-10
Abstract: Three-dimensional moulded pressings, partic. for the furnishing of motor vehicle interiors, are produced from a pre-bonded fibrous web of cellulosic or ligno-cellulosic fibres sandwiched between two carrier sheets of limited extensibility such as paper, metal or plastic film, fabric, etc., which have an array of short slits oriented perpendicularly to the direction of deformation, whereby the deformation of the web is uniformly distributed, and after the forming operation the web remains as a continuous sheet which is bonded to the carrier sheets. The carrier sheets may be attached to the web by a coating of adhesive on the inner faces, or they may be stitched or bonded together through the web with soluble stitches or bonds. This structure permits the formation of thin-walled pressings in a single operation without rupturing the fibre web. The fibrous content may be of short, waste fibre from other fibre-processing machinery, and the carrier sheets may comprise a wide range of materials, with greater thickness and strength than was possible with earlier processes.
Patent DE-3015062-A1 (DE)
Title: Dynamic control of final amplifier in transmitter - contains operation within limits of linearity of amplifier, to minimise interference
Inventor: AIGNER WERNER ING GRAD
IPC: H03G7/06
Filed: 1980-04-18
Abstract: The application is to a transmitter amplifier feeding one of a number of frequency channels in a carrier frequency transmission system. Particularly, it is concerned with amplifiers having a final transistor stage with a variable output resistance. In order to minimise the occurrence of cross talk or interference between channels the gain of the final stage amplifier is changed when the output exceeds a set value. This is achieved by measuring the collector-emitter voltage, comparing it with a reference, and applying the difference to a level detector. The detector output then operates on a gain changer to reset the amplification. The voltage may be assessed by comparing collector and emitter voltages separately with a set reference rather than making a direct measurement across the transistor.
