Title: Waste paper recycling - uses electrolyte and foaming to develop a flocculant to remove dirt as a scum from the surface of processing water
Inventor: GEORGIOS TROUBOUNIS DR
IPC: C02F9/00
Filed: 1992-02-28
Abstract: Recycling process it is sepd. in a flotation tank. The surface scum and its dirty water is cleared by means of foaming and skimming. Pref. the bales of waste paper are opened into the recepticle (1) which has a source of additional clean water (34) through the tank (3), as required.

Title: Maintaining constant nip in rolls of rolling machine - involves moving adjacent ends of both rolls of pair in opposing directions away from common starting plane
Inventor: STEIN HERMANN
IPC: B21B13/02
Filed: 1992-03-17
Abstract: In a process for maintaining a constant nip between the rolls of a rolling machine during operation, the axes of the pair of rolls, which initially start along a common plane (E), are moved away from each other such that the adjacent ends of the pair of rolls move in opposing directions away from the starting plane (E). Appts. for adjusting the roll nip comprises an arrangement which changes the position of the roll journal bearings, relative to each other. Movement in each roll end away from the common plane (E) is approx. the same and is almost at right angles to the plane (E). Each roll journal for the first pair of rolls is carried on arms mounted on horizontal supports. The journals of the second roll pair are mounted on arms pivoted on the supporting arms for the first roll pair. The supporting arms for the first roll pair are pivoted on the horizontal supports. In some cases the pivots of arms for both rolls may coincide. USE/ADVANTAGE - The process and appts. maintain a constant nip over the whole length of the rolls of a rolling machine used in prodn. of chocolate, paint, paper or hot or cold rolling. The nip is maintained constant even under conditions of heavy loading, heat and roll wear.

Title: Plastics components heating and drying - has heating chamber with external air drying unit to extract carried moisture in the recirculating air and raise its temp. before return to the chamber.
Inventor: HAAS CHRISTOPH
IPC: F26B21/08
Filed: 1992-10-28
Abstract: A flow of heated air in a circuit is used for predrying and/or annealing plastics components to deliver drying heat vapour to the components, with steam take-up which raises its relative humidity. At least one part-flow is taken from the moisture-laden and cooled section of the drying air circuit, to be led into an adjacent circuit and through a porous filter of a hydrophilic material to absorb the moisture content, and the air is returned to the main circuit. The cooled air, through further reduction of its moisture, is heated and the regenerated drying air is returned to take up moisture again. Also claimed is an assembly with a separate air drying unit (20) with air channels (30, 31) for the adjacent circuit for the air part-flow. USE/ADVANTAGE - The system is for the treatment of plastics plate material and the like, as semi-finished prods. where they may have absorbed moisture in transit between the prodn. point and the customers finishing station. The operation gives an effective moisture reduction in the components with a high steam pressure difference between the components to be treated and the drying air, with a consistent moisture take-up, simply and with little energy.
Patent DE-4237623-A1 (DE)
Title: Clutch cover for motor vehicle transmission - contains contact pressure plate with lining and elastic element to transfer drive force
Inventor: UENOHARA NORIHISA
IPC: F16D13/71
Filed: 1992-11-06
Abstract: The clutch cover is shaped like a keyhole or plate and contains the contact pressure plate (12) which presses the clutch disc (2) against the input rotation part. A membrane spring (11) held by the clutch cover (10) drives the contact pressure plate in the direction of the input rotation part whilst the elastic element (16) between the pressure plate and spring transfers the driving force of the spring to the plate. The elastic element is also a plate spring (16) held by its edge in a socket on the pressure plate. ADVANTAGE - The damping characteristics can be maintained for a long time since the elastic element is on the side of the pressure surface less exposed to the high temperatures in the clutch disc.

Title: Identifying traffic through monitored zone - analysing geophone signals corresp. to sound waves triggered by traffic and propagated underground
Inventor: BECKER GUNNAR R
IPC: G08G1/015
Filed: 1992-11-09
Abstract: The method involves receiving sound waves, at a geophone (10), stimulated by traffic, coupled into the ground and propagated underground. Corresp. geophone output signals are generated. The categories of the different traffic elements, e.g. pedestrians, light motor vehicles, heavy vehicles are associated with frequency ranges, each defined by an upper frequency. The upper frequencies are staggered and measurement signals are derived by envelope curve detection. The measurement signals levels are compared continuously with the level of a reference signal also derived by envelope curve detection in the background noise frequency region. Measurement signals in a frequency range with levels exceeding the reference signal level are preliminarily categorised as associated with that frequency range. Further test criteria are then applied to confirm final categorisation. USE/ADVANTAGE - Identifying various types of traffic passing through monitored zone. Simple detection and classification.

Filed: 1992-11-20
Abstract: The longitudinal axis(29) of the image receiver(17) is inclined at an angle, wrt the plane of the pin tops (18) and wrt the vertical on this plane. The radiation source(16) radiates the pin tops at a large angle(19) wrt the image receiver axis(29). The radiation results across a shade edge(26), which shades off the base region(25) of the plug block(14) from the plug pins (12). Several positions(I,II,III) are provided for the image receiver (16) in relation to the pin group being tested. The radiation source and/or the receiver can be swivelled in these positions or arranged fixed to be switched from alternate sides. ADVANTAGE - Quality testing during prodn.. Reliable identification of faulty pin blocks using appts. at lowest possible cost.
