Title: Automatic distribution of dough pieces on proving oven band - using stepwise conveyor with cup section slats along which dough containers can be moved sideways to position dough pieces in rows on band
Inventor: KOENIG HELMUT DIPL ING
IPC: A21C9/08
Filed: 1980-07-21
Abstract: System for feeding cakes of dough onto a board to take them through a proving oven has a conveyor formed from a set of slats. Each slat has a cup section and consecutive slats have slots in the base to allow movement of the dough holders. Dough cakes are discharged from a conveyor, e.g. in sets of four. Slat into which they discharge them moves forward. At the same time, the slot in the base allows operation of a pusher from the side to move the set of cakes along and position them. The length of the slot determines the lateral position of the cakes. This intermediate conveyor discharges onto the band inside the proving oven to give rows of 16 cakes. System is for use in bakeries etc. to provide automatic presentation of dough cakes to the proving oven. The system requires little space and at the delivery point allows some variation in the number of cakes per row.

Title: Rapidly repairing conveyor belts - by curing adhesive coating on damaged area by applying hot sand when stationary
Inventor: ALMES CHRISTINE
IPC: B29C35/00
Filed: 1980-10-31
Abstract: Rubber type conveyor belts are repaired by coating the damaged areas with adhesive and hot curing by applying heat directly with a heated powder such as sand 1 cm thick or more. The process uses locally available powder and dispenses with any special heating equipment for the belts. Providing it is a fine powder, it is easily removed when the belt recommences ooeration. The thickness of powder depends uoon the width of the belt and the size of the damaged area. It is manually applied quickly and simply by shovelling uniformly over the damaged area when the belt is stationary. Quick method, hence min. interruption to operations, can be used for any profile belt.

Inventor: MITTER MATHIAS
IPC: D06P1/96
Filed: 1981-03-12
Abstract: Process for applying liquor in foamed form to goods containing fibrous material, such as piece goods or fabric webs. Prior to application of the foamed liquor to the fibrous material there is carried out a pretreatment in which at least one identical or similar constituent of the liquor present in the foam is applied. This pretreatment generally consists in wetting, impregnating or soaking the material. Then the pretreatment liquor can be partially removed again from the material, so that a residual moisture content remains to subsequently apply the liquor to the fibrous material in foamed form. The aftertreatment, namely the application of the liquor or else of any other desired chemical in foamed form to the fibrous material, is then effected by an applicator either directly on the material or with interposition of a sieve or a screen printing screen. The aftertreatment can involve dyeing, printing, finishing or else coating the material. Similarly, a textile dressing can be applied to or incorporated into the material.

Patent DE-3121087-A1 (DE)
Inventor: EILERS NORBERT DIPL PHYS
IPC: G08G1/09
Filed: 1981-05-27
Abstract: FM transmission system in which, besides program content, an auxiliary carrier of, for example 57 kHz, is radiated, which auxiliary carrier is modulated by an announcement recognition (AR) signal and by a region or radio-station recognition (RR) signal, the AR and RR signals being low-frequency, AM modulations on the auxiliary carrier. To enhance recognition of an AR signal, e.g. between 142 and 170 Hz, is enhanced, in spite of reception difficulties, for example due to multi-path reception and the like, by decreasing the modulation of the 57 kHz subcarrier by the RR signal to 30% or less, while the AR signal is modulating the subcarrier, so that the AR modulation may extend to 60 and even 90% modulation. Multiple AR frequencies can be used, for example to characterize different announcements, e.g. in different languages, or of different characteristics, such as traffic, news, sports, or others, recognition of the AR signal in the receiver permitting switch-over from other reproduced programs, e.g. tape, to the demodulator from the receiver tuned to the station emitting the AR signal, to reproduce the announcement, or the like.

Title: Method for monitoring the charging of accumulators
Inventor: PREUSS PETER DIPL ING
IPC: G01R31/36
Filed: 1981-07-22
Abstract: To monitor the charging of accumulators, it is intended to check the variation of the charging current with time by measuring at periodic sampling intervals. This is intended for early recognition of possible faults of accumulators and charging devices and preventing damage by an increasing charging current. During the sampling interval, the analog signal of the charging current output by a sensor is converted into a digital value and compared with the digital value of the charging current from the preceding sampling interval which is already present in a memory element. If the value of the charging current measured is in each case above the stored value from the preceding interval in a number of successive - for example five - intervals, the variation of the accumulator voltage with time is additionally checked in accordance with the same method. Following that, an error message containing information on the trend of the voltage variation is indicated and the monitoring process or charging process is terminated.
