Title: Stacking conveyor for flat and overlapping objects - has two vertically overlapping belts with adjustable transfer point
Inventor: WANGERMANN JOCHEN DIPL ING DR
IPC: B65H33/12
Filed: 1976-09-08
Abstract: A belt conveyor for flat objects which overlap along their leading and trailing edges is used to separate their continuous flow into individual horizontal stacks. For this purpose, the supply belt (7) which is located near and above the stacking belt (19), runs at a slower speed. In order to shift the transfer point between the two conveyor belts along the direction of the stacking belt (19), the belt length of the supply belt (7) can be increased. Thus the forward speed of the transfer point equals the belt speed of the stacking conveyor. When a gap is required, the movement of the transfer point is momentarily reversed whilst the actual belt speed and direction is maintained.

Title: Purifying waste water of high organic content - first acid anaerobic, then aerobic, then anaerobic methane fermentations
Inventor: GRAU PETR
IPC: C02F3/30
Filed: 1976-09-16
Abstract: Process for the purificn. of waste water having a high content of organic material comprises several stages. The first stage is initially anaerobic fermentation by means of a microbial culture at 20-50 degrees C in acid medium for a residue time of 0.1-0.8 d. kg-1.m3 with conversion of the contained oxygen to a mixt. of organic acids; this is followed by aerobic fermentation for a residence time of 0.03 d. kg-1. m3. At the second stage the mixt. is submitted to an anaerobic methane fermentation by an anaerobic microorganism culture for 6-15 days. The resulting mixt. may then if desired be further purified by a second aerobic stage. By present methods involving an anaerobic followed by an anaerobic stage, in the 1st stage, e.g. methane fermentation, the acids formed lower the pH and inhibit the fermentation. Chalk is used to neutralise the acid but this complicates the process. The above process converts the acids to CO2/water resulting in simplification of the process and avoidance of the use of chalk.

Title: Hydraulic motor with reversing and relief valve - has pressure operated spring loaded valve acting on relief valve to limit pressure
Inventor: REITEN KJELL
IPC: F15B11/02
Filed: 1976-11-16
Abstract: The hydraulic motor (18) circuit has a reversing valve to direct the medium via a first or a second flow path, and a relief line with pressure operated relief valve whose inlet is connected to the first flow path whilst its outlet is connected to the outlet of the reversing valve. The pilot line of the relief valve runs via a control valve to the second flow path. The control valve is actuated by the pressure in the first flow path against an adjustable spring and, in its open position, connects the first to the second path via the pilot line so as to admit an intermediate pilot pressure to the relief valve thus opening it. This opens a connection to the outlet of the reversing valve and raises the pressure in a branch from the relief line to the control valve causing the latter to move against the spring thus limiting the pressure in the first flow path.

Title: Large gas duct with internal liner and insulation - has elliptical hollow partitions circumferentially and axially
Inventor: HODZIC ALIJA DIPL ING
IPC: F16L59/02
Filed: 1977-02-09
Abstract: A straight or curved pipe or duct of large bore is thermally insulated and is intended for gaps at high temp. and speeds of flow, where sudden pressure changes can occur. The duct comprises an outer pressure tube and an inner gas guide tube, the annular spaces between them being subdivided into separate chambers to prevent forced circulation of gas in the space from occuring, to the detriment of the insulating effect. The subdivisions of this annular space are provided by thin-walled tubes of elliptical cross-section, the smaller dia of the ellipse being somewhat smaller than the radial dimension fo the annular space, when in the initially built condition. some of these sealing elements form rings or parts of rings following the circumference of the tubes, while other sealing elements run parallel to the axis of the duct and joint to the former to form compartments. Each compartment contains numerous layers of parallel radiation sheets or foil insulation, shaped to suit the appropriate section of the duct. Individual layers of these sheets overlap. Used in particular for closed gas circuits for high temperature reactors and process heating plants, also for fast breeder reactors, where the ducts are part of a coaxial gas system. The insulating action is uninfluenced by forced convection and remains effective after many years in operation.

Title: High resolution colour TV projection system - has black=and=white CRT and colour tube driven by difference signals
Inventor: SCHADE KURT DIPL ING
IPC: H04N9/31
Filed: 1977-03-18
Abstract: The colour T.V. projection system comprises a common projection screen and optical arrangement in which the picture information is displayed by means of c.r.t.s. One c.r.t. is a black-and-white type driven with high beam current so that it produces a high-intensity luminous output without the need for excessively EHT voltages with the attendant risk of X-ray generation. Since the b & w tube has no shadow mask, this again contributes to greater sharpness and luminous intensity. The tube can be driven with EHT below 30 kV. The second tube is a conventional colour t.v. picture tube which is controlled with narrow-band colour-difference signals only. Since the colour picture is projected by means of a single system, the colour purity and convergence problems associated with other projection systems using several electron guns for different colours, are minimised.
