Title: Auxiliary water dispenser device for lavatory cisterns - has valve system which only allows water to flow whilst it is open and is independent of normal flushing mechanism
Inventor: BINGGESER ULRICH
IPC: E03D1/14
Filed: 1975-01-09
Abstract: An auxiliary device is used for dispensation of quantities of water in specified time intervals during which the device operates. It may be built into lavatory flushing systems in which the float or bell type total emptying system is used and in which flow of water is maintained after complete valve opening, there is a valve which is limited in its opening extent and which is immediately closed again by its own weight and that of the water in the storage cistern in order to allow only that amount of water to flow that can escape during the period of its opening. Normal flushing by the cistern is still possible and twin operating devices are provided on the cistern.

Title: Removing unrecoverable vinyl chloride from air spaces - by leading into central pipe equipped with air blower-safety discs
Inventor: JACOB HELMUT DIPL ING
IPC: B01J19/00
Filed: 1975-03-21
Abstract: Unrecoverable vinyl chloride monomer is removed from the air space surrounding polymsn. appts. by (a) passing the vinyl chloride into a common central release pipe having suitable dimensions relative to the amt. of vinyl chloride, and (b) constantly flushing the pipe with such an amt. of air that the gas velocity at the outlet position from the pipe is 2-20m/sec. When large amts. of vinyl chloride are suddenly released, these are allowed to escape into the open air after tearing safety discs placed in the central release pipe. Reduces the concn. of vinyl chloride in the air space surrounding polymsn. appts., including the space under the roof, to acceptable levels, thus avoiding risks to the operating staff. The appts. is cheap and simple, and can be easily fitted to existing buildings.

Title: Steam boiler with fly ash collector - returns fly ash to fusion chamber for removing as molten slag
Inventor: EILERS FRITZ
IPC: F23C9/00
Filed: 1975-06-10
Abstract: The solid fuel steam boilder has a downstream dust separator and fly ash feedback system. The fly ash is blown through a number of nozzles into the combustion chamber, with a fusion chamber for molten slag having a slag outlet. This system is used to releive the loading on filters or dust separators to a significant extent by collecting a larger proportion of the blown fly ash and removing it by melting. This ensures that operation of the plant is not interrupted. The fly ash nozzle (12) is arranged in the region of the fusion chamber floor (9) and the fly ash is blown at an acute angle against the molten slag surface. The stream blown through the fly ash nozzle impinges on the molten slag surface at an angle of 20-45 deg.

Title: Continuous enzymatic treatment of plant or animal tissue - using pref. cylindrical reactor fitted with guided conveying device
Inventor: KOHLBACH FRED DIPL ING DR
IPC: A23L21/10
Filed: 1975-06-16
Abstract: Enzymatic treatment of plant or animal tissue takes place continuously. The material to be treated is moved, through a reaction (e.g. cylindrical) vessel, with a narrow period of dwell spectrum, by means of a guided conveying device (e.g. slowly rotating screw conveyor). Process is used esp for prepn. of fruit- and vegetable juices, fruit- and vegetable pulp; for digesting plant or animal tissue prior to extn. processes; for prepn. of protein hydrolysates for human nutrition or as animal feedstuffs; for prepn. of organic fertilisers from waste; for collagen recovery from skin waste. A single continuous enzyme treatment appts. can be used in place of several, intermittently working enzyme treatment reactors. Increased expenditure is compensated by limitation to one appts. in place of several devices working in parallel. Process allows introduction of one or more enzymes at desired positions. Different treatment times can be used for different enzymes. Conditions can be altered along flow-path.

Title: Measurement of absolute vehicle speed - involves system of second vehicle with speed compensating network for measuring time intervals
Inventor: GRUENBERG WOLFGANG
IPC: G01P3/64
Filed: 1975-06-27
Abstract: The speed measuring system can be used in a vehicle to measure other vehicle speeds. A measured value V21 for the other vehicle speec is obtained by measuring the time interval DELTA T taken by the other vehicle to pass two points in the measuring vehicle, and this value is stored. Values V2 (1) and V2 (2) for the absolute speed of the measuring vehicle are measured in time intervals DELTA t  DELTA T starting at times t1 and t2 at which the other vehicle reaches the measuring points, and these values are stored and their mean obtained V2 . The absolute speed V1 of the other vehicle is found by adding V2 to V21 if the other vehicle is overtaking the measuring vehicle, and subtracting V21 from V20 if the measuring vehicle is overtaking the other vehicle, and subtracting V2 from V21 if the vehicles are travelling in opposite directions.

Title: Detachable bulk container for road and rail trucks - has gantry crane to reduce waiting time of carrier vehicle during unloading
Inventor: WEDLER KLAUS DIPL ING
IPC: B65G67/24
Filed: 1975-12-24
Abstract: To increase the efficiency when unloading bulk from road or rail vehicles, the bulk containers (4) can be detached from the carrier vehicle. The full container is first lifted by the dipper mechanism of the truck (3). A stationary support frame (13) then takes over the container and holds it in a vertical position above a conveyor belt (12). To unload bulk containers from railway trucks, a gantry crane is provided which transfers the containers from the truck to the discharge conveyor. The carrier vehicle is thus able to collect an empty container without waiting time.

Title: Centring of symmetrical workpiece on inspection gauge - uses test signal derived from feeler gauge, which is corrected to determine necessary movement
Inventor: HEIDER HANS-JUERGEN ING GRAD
IPC: G01B7/312
Filed: 1976-11-27
Abstract: The workpiece is placed on an adjustable and tiltable centering table, and its surface is traced along its periphery in lines running radially to the feeler axis. A correction signal is subtracted from the signal so obtained, and as a result a display signal free from eccentricity component is produced. Amplitude of the test signal for at least one fixed point is stored. The centering table is then moved and the sum of the amplitude of the correction signal corresponding to this point, and of the measurement signal changed by the table movement, less the amplitude of the stored signal is made equal to zero. After this, a correction signal for further surface tracing is re-determined.
