Title: Pulse generator with selector switch - picks one of two VCO to ensure rapid phase locking
Inventor: REISINGER KONRAD DIPL ING
IPC: H03L7/10
Filed: 1979-09-25
Abstract: The pulse generator produces an output pulse sequence whose frequency is a given multiple of an input pulse frequency using two voltage controlled oscillators. The input sequence (fex) is phase compared (DIS) with a feedback signal (fin) to produce the error signal (Ur) that controls the two voltage controlled oscillators (VCO1,VCO2) via a low pass filter (TP). A changeover switch (SW) connects either the output of one vco or the output of the other vco through to the generator's output (F, equal to n,fex) and through to a frequency divider (FT). The frequency divider produces the feedback signal. The switch is controlled by an error signal range indicator (RBI). The range indicator detects when the phase difference is large or small and causes the changeover switch to select the vco appropriate for reducing the phase difference.

Title: Scouring beck with rollers having internal bearings - and external seals which maintain internal air pressure in rollers
IPC: D06B3/12
Filed: 1979-11-17
Abstract: A scouring beck for, partic. synthetic filament tows, has several sets of rollers within the liquor alternating with mangling rollers above the liquor, each rollers comprising a cylindrical shell mounted on internal bearings on a fixed shaft which is attached to the inner wall of the machine housing. To protect them from the wash liquor, the roller bearings have external seals whose integrity is monitored by connecting the interior of the roller to a compressed air supply and metering the air flow, which increases on breakdown of a seal. The mangle rollers are carried in a narrow frame supported on a rail by rollers which allow the mangle assembly to be run out of the machine for inspection and maintenance. This construction allows the rollers to be set close together without bulky bearings preventing access between neighbouring mangling assemblies, and enables the machine to be completely enclosed without complications introduced by bearings which pierce the housing.

Title: Local test circuit for programme controlled telephone exchange - operated independently of test and check facilities of exchange computer
Inventor: KARLSTETTER DIETER
IPC: H04Q3/545
Filed: 1979-12-20
Abstract: The automatic test circuit is used to enable testing of exchange sections which would otherwise impose considerable requirements upon the exchange central processor (ZST). The circuit is typically used in checking out the connection system (KF) between subscribers (TN) and the rest of the exchange equipment. Test units (PE1,PE2) are provided, one to simulate a calling subscriber (PE1) and the other a called subscriber (PE2). A local control circuit (ST) regulates the test programme. At set intervals, a simulated call is set up through the connecting system (KF) between the two test units. This operation changes the loop impedance and connects a number selection memory (WAS). After a limited timed interval, the connection is broken. A voltage sensitive discriminator senses the potential changes during the test process. If these do not conform with the correct values for a healthy circuit a fault condition is signalled.

Patent DE-3008288-A1 (DE)
Title: Telephone equipment incorporating person search facility - has auxiliary call number storage register connected to local radio transmitter, with radio link to mobile alarm units
Inventor: JAEGER HORST
IPC: H04M11/02
Filed: 1980-03-04
Abstract: Subscribers (A,B,etc.) can be connected with each other through conventional line scanners and connectors (TAa,TAb) with a couple field (KF) and a register (R) via a connection unit (VS). If the intended called subscriber does not reply, the calling station proceeds to dial a search number causing both the calling and the called subscriber numbers to be transferred into a storage register (AS) which has several storage positions (1,2,3 ...). This store is connected with a person search unit (PSE) through individual connectors (APSE). If the dialled station does not reply the caller adds a search command signal. A recoded address is radiated by a radio-transmitter and received by an on-person alarm unit. The called subscriber dials an answer code plus his own subscriber number from any station and thereafter is connected to the caller. Also, some subscribers have no telephone of their own, only the mobile alarm units. No special search command is needed since all such calls are at once stored in store (AS) and routed as outlined. Additionally, there is a selective right to reach a subscriber away from office. An individually allocated search command code - known only to few - is compared with a corresponding stored number held in memory for each such subscriber station, and when coincident releases the radio call signal to the subscriber.
Patent DE-3008721-A1 (DE)
Title: Recycling ready mixed concrete remnants - in silo with spherical bottom and agitator
Inventor: DAMANN FRANZ-JOSEF
IPC: B01F7/00
Filed: 1980-03-07
Abstract: Vehicles which have been used for the transport of ready-mixed concrete have to be cleaned out daily. The dumping of the scrapings in special depositories causes a considerable expenditure. Their disposal can be saved by a simple recycling process, using a silo into which the concrete remnants are charged under water. The silo has a hemispherical bottom and an agitator of similar shape which is kept in constant motion so that no particles can stick to the bottom. This treatment washes all binder out of the concrete and saves the dumping costs.
