Patent DE-2657232-A1 (DE)
Title: Bagasse preliminary dewatering process - has successive press zones of different depths below low-pressure roller in diffuser
Inventor: KAETHER WILLY
IPC: C13B15/00
Filed: 1976-12-17
Abstract: The process reduces the moisture content of bagasse passing through a diffuser and then treated in high-pressure dewatering mills. The sugar conent is washed out on the contra-flow principle in the diffuser extraction zone by spraying with extraction fluid, and preliminary dewatering is effected by a low pressure roller inside the end of the difuser itself, this roller being of large diameter. During the continuous operation of this roller, the bagasse underneath it is subjected to multiple inversion, being fed to two different-shaped and successive press zones, the second one being deeper than the first, and with a sieve surface comprising a series of ridged sections, as compared with the preceding flat one. Under the effect of the different press zone depths and the curvature of the roller, the originally flat mass of bagasse is transferred in a curved form.

Title: Fibre flock cleaning unit - has a perforated support surface with air bursts from below and air suction above
Inventor: TRUETZSCHLER HERMANN
IPC: D01G9/08
Filed: 1976-12-18
Abstract: An air flow is passed through fibre flock material, to clean it by removing dirt and dust, the flock material being placed on a porous supporting surface. Jets are placed under the supporting table surface to deliver compressed air through the support openings and through the flock material. Heavy dirt particles drop down through the openings in the supporting surface, while light dirt and dust is extracted by an upper suction unit. As the flock material is not pressed against a surface by suction, it remains loose and manageable, while the dirt and dust is sepd. and removed easily.

Patent DE-2704132-A1 (DE)
Title: Ultrasonic fault testing method - uses discriminator having two threshold levels for statistical interference suppression
Inventor: PAWELLETZ REINHARD
IPC: G01N29/38
Filed: 1977-01-28
Abstract: The signal derived from a fault detected by an ultrasonic testing apparatus exhibits an amplitude variation (A) which varies with time (t). The variation depends on the relative velocity of the sound between the test object and the test head and the nature of the fault. In order to permit discrimination between signals from a fault and interference signals, a second threshold is introduced in addition to the discriminator threshold usually specified. The two discriminator threshold levels permit two modes of statistical suppression of interference signals which are, by definition, sporadic and non-recurrent. In the first method the statistical suppression commences immediately the second threshold level (2) is exceeded and either the signals exceeding the first threshold level are read directly as fault signals or they are stored for long enough to permit the statistical suppression to be carried out. In the second method, statistical suppression commences when the first threshold level (1) is exceeded.

Title: Heating of fish bearing waterways - involves equipment such as solar collectors or blowing of warm air through water
Inventor: SOELCH ROLAND
IPC: A01K61/00
Filed: 1978-11-30
Abstract: The device is for providing heat to fisheries and fish-bearing lakes to aid fish breeding. Specifically, a fish-bearing waterway is heated above its natural temp. level while using a natural heat potential source. This can be effected with the aid of solar collectors or radiation energy collections. The solar collectors are designed to float on part of the surface to heat the water directly. Alternatively, warm air can be blown into the water to heat it and increase the oxygen content. An increase in fish production is obtained without the use of scarce and expensive fuels.

Abstract: The windshield for a motor vehicle is characterized by a transparent panel having a lower region normally outside the driver's field of vision and where at least one windshield wiper is located in the rest position of the wiper. An electric resistance heating element, formed either as a continuous layer or as a plurality of individual conductors connected in parallel by bus bars, is carried on the windshield only in the lower region for heating the area on which the wipers rest. A continuous layer of a heat radiation absorbing ceramic material opaque to ambient light and coextensive with the area of the heating element is disposed on the windshield between the heating element and the windshield wiper to shield the heating element from view from the front of the windshield and to uniformly distribute heat over the lower portion of the windshield. The windshield is a laminate including inner and outer glass panes with a plastic layer therebetween. The heating element and opaque layer may be disposed on the inner and outer surfaces of the outer pane, respectively. Alternatively, the heating element can be disposed between the panes and the opaque layer can be provided on either the inner or outer surface of the outer pane. The opaque layer can be provided on the exposed surface of the inner pane, the heating element disposed thereon, and a second opaque layer of lower heat conductivity provided thereover to form a protective covering.

Title: Deicer for heat pump evaporator - includes pressure sensors in narrow gap between plates to operate switch when ice forms
Inventor: KOHNKE HANS-JUERGEN DIPL ING
IPC: F25D21/02
Filed: 1979-06-02
Abstract: The evaporator for a heat pump, consisting of a set of plates (e.g. 6) spaced apart from each other, includes an automatic system for preventing excessive ice formation on the plates. An additional plate (5) is incorporated, forming a narrower gap (8) than that between the other plates. Near the top, where ice formation is at a maximum, a pressure sensor (10) is mounted in the gap. A second pressure sensor (11) is located lower down, where ice formation is less. These respond to an increase in pressure of the flow of air (5) blown between them to operate an electrical switch (S) controlling an ice removal system.
