Patent DE-2555905-A1 (DE)
Title: Radio direction finding apparatus - is for automatic discrimination of low field strength signals in engaged radio bands and uses widely spaced aerials
Inventor: HERZAN HANS ING
IPC: G01S3/74
Filed: 1975-12-12
Abstract: Signals are generated either by low power transmitters at a short distance or by higher power transmitters at a greater distance. The direction finder bearings obtained are displayed on a screen. A direction finder is automatically periodically connected by a switch to two or more direction finding aerials at a distance from each other, limited by possible lengths of cables. Bearings are then the same for a distant transmitter but different for a transmitter at a short distance so that a fix can be obtained.

Title: Flexible extermination cover for rodent extermination tunnel - is pressed over tunnel with damp minerals to expel air and light
Inventor: GERHARDT EUGEN
IPC: A01M23/00
Filed: 1975-12-18
Abstract: The tunnels which are opened up are mechanically processed by a cover by clay, lime and other soil constituents into a partially wet state and pressed down. The mass filling the cover is kneaded to a flexible state and is then pressed onto the opening of the tunnel to make it air tight. The rodents inside the tunnel are not frightened off because the materials are familiar to them and they are therefore ready to accept any poisoned bait which has been laid for them. Should poison gas be used, the gas residue cannot escape back. To retain the moisture content an odourless salt may be added to the mineral.
Patent DE-2558410-A1 (DE)
Title: Two-stage sintering of magnesite or dolomite - for use as refractories e.g. in steel prodn. and cement mfr.
Inventor: SCHULTE HANS GERD DIPL ING
IPC: C04B35/06
Filed: 1975-12-23
Abstract: Two-stage process for sintering magnesite, dolomite or the like, comprising preliminary heating, compacting the material and heating again, is improved in that the starting material is comminuted to flour consistency (1.0 mm, pref. 0.2 mm) before the preliminary heating, which is performed whilst the material is in the suspended or whirling state, opt. in several steps. Sintering aids, such as iron oxides, alumina, silica, or the like can be added. The heating and CO2 removal during the preliminary heating can be effected using hot gases from the final sintering stage. The preliminary heated material is briquetted by pressing at 500-800 degrees C. Sintered magnesite and dolomite are widely used for the prodn. of refractory stones, ramming lining compsn. and the like. The fine comminution facilitate the CO2 expelling, and reduces the porosity of the product. There is no need for cooling before the briquetting and the final heating.

Title: Printing press strip datum mark automatic detector system - uses detectors in geometrical configuration aimed at mark with inclined edge
Inventor: STOEFFL VOLKMAR DIPL ING
IPC: B65H23/04
Filed: 1976-09-27
Abstract: The equipment automatically detects a datum mark when adjusting a strip of material passing through a machine, partic. a rotary printing press. The datum mark has a predetermined geometrical shape, with one or more edges inclined to the travel direction, and aimed at the area on which the marks are printed are a number of optical detectors mounted at the corners of a predetermined geometrical figure. An unprinted surface causes them to emit a 'bright' signal, and a printed one a 'dark' signal. A computer combines the signals from the detectors into logic form and determines, taking strip speed into account, one or more specific characteristics. These are compared with that of the datum mark, and when a mark is shown to be present the computer generates a release signal (f) for the alignment error detection equipment. If it is not present, a computer resetting signal is emitted.

Title: Partial extrusion of ring blanks - to mfr. workpieces with major and minor diameters
Inventor: SUTHOR ARTHUR
IPC: B21C23/18
Filed: 1977-01-20
Abstract: Workpieces are made by the partial extrusion of a blank into a die. The extrusion pressure is applied as a sudden impact via a rotating flywheel which is not driven at the moment of impact; the extrusion stroke is restricted; and the blank is forced into an open die. The pref. plant includes a flywheel which is the middle disc of a friction screw press, driving a piston fitted with a punch and a stop plate limiting the punch stroke, so the depth of travel of the punch into the die is restricted. For the mfr. of hollow workpieces, a tubular- or ring- blank is used, and a mandrel is mounted on the punch. The amt. of heat transferred to the die is reduced, so the working life of the die is increased without the need for special cooling.

Title: Optical homogeniser for phase comparator range finders - has guide with convex or concave profile input face
Inventor: MANHART SIGMUND LUITPOLD DIPL
IPC: G01S7/481
Filed: 1977-01-21
Abstract: The optical homogenizer for phase-comparator type range finders transmits a greater amount of the original beam energy from the source through the guide by homogenization of the phase. Instead of the input face of the guide being a plane one as is usual, this face is made convex, concave or constructed from a series of convex and concave areas. This ensures that full phase mixing is achieved and the main part of the radiation is conveyed symmetrically to the geometric axis of the beam guide (214). From a constructional point of view, it is no longer necessary to accurately align the guide or match its diameter and length to the active radiating face of the source (211).
Patent DE-2709951-A1 (DE)
Title: Sugar cane bagasse stockpiling - in open air heaps after removing heavy impurities and adjusting moisture content
Inventor: RUCKSTUHL KONRAD
IPC: C13B15/00
Filed: 1977-03-08
Abstract: Sugar cane bagasse used for the prodn. of furfural is stored and processed by removing heavy impurities (sand, metal particles) in a water flushing tank. The moisture is removed by a press operation, leaving the bagasse slightly absorbent. Spraying with waste water from the furfural process raises the moisture to that required before the bagasse is stockpiled in large open air heaps. The danger is spontaneous combustion is eliminated and the labour of drying and storing in bails which have to be unpacked is saved.

Title: Interference pulse suppression circuit - detects pulses and replacement synchronisation pulses are applied to amplitude filter
Inventor: WEISS CHRISTOPH DIPL ING
IPC: H04N5/213
Filed: 1977-08-22
Abstract: The interference pulses reach a TV receiver together with synchronisation pulses. The receiver has a flip-flop(KS) synchronised by the received colour picture blanking synchronisation signal(F)(BAS). Its cycle periods are only a little shorter than the normal pulse duration of the colour picture blanking signal. An interference detector(SD) monitors this signal during periods of picture signal transmission, and/or during synchronisation pulses, for presence of interferences which could upset the synchronisation. In case of their presence, individual replacement synchronisation pulses, controlled by the flip-flop(KS) together with a control unit(ST), are applied to the amplitude filter(AS) input.
Patent DE-2743844-A1 (DE)
Title: Calendar rollers eliminating convexity and resetting - by having dia. of last roller excessive and shifting penultimate roller
Inventor: SALO ESKO DIPL ING
IPC: D21G1/00
Filed: 1977-09-29
Abstract: The parent patent discloses how the last gap in a calender, esp. for rubber or plastics, is controlled by running the shafts of at least the three last rollers at their original setting in the same plane, the last gap (which is smaller at the centre than at the edges) being adjusted to a constant value over its whole width while the penultimate roller is shifted parallel to but out of the common plane. In this addn. the three last rollers are cylindrical and their dia./gaps are such that the last two, when in the same plane, are equally deflected under load. The dia. of the last roller however is greater than necessary so that it is deflected less than the penultimate roller, and the last gap is adjusted by parallel shift of the penultimate roller.
