Patent DE-2332365-A1 (DE)
Title: Sealing off brine leaks in salt workings - compressed air injected to dry brine and precipitate salt as crack sealant
Inventor: WEHNER HEINZ
IPC: E21F17/16
Filed: 1973-06-26
Abstract: Sealing off brine feeders leaking into underground salt deposits and working rooms is carried out by injecting compressed air into the cracks carrying the brine. This has the effect of forcing the brine back and additionally cooling and thus drying the brine with the result that the salt is precipitated. This in turn closes off the feeder cracks and other flow paths and preventing further ingress of brine, either from overlying water-bearing beds or from inside the rock itself in the form of connate brine. A single hole is all that is required as the air pressure soon forms a bubble or blister inside the rock, and once certain paths have been closed the air spreads to other voids, e.g. feeder cracks and so fills these up likewise.

Title: Collapsed hollow plastic articles - for space saving during transport and subsequent restoration to original shape
Inventor: BOSSERHOFF GEORG
IPC: B29C35/08
Filed: 1973-09-01
Abstract: Saving of space in the transport of bulky plastic articles, e.g. injection moulded or deep drawn containers, extruded tubes etc., by deforming the cross-linked thermoplastic article after cross-linking to the rubber-elastic state into a space-saving shape, allowing it to cool and at a desired later point of time returning it to its original shape by heating to temps. at which it is again rubber-elastic. Suitable polymers are polyolefins, e.g. high or low density polyethylene, copolymers of ethylene with e.g. propylene or vinyl chloride, graft polymers of polyvinyl chloride and polyethylene etc. Suitable cross-linking agents are peroxides, polymerisable monomers e.g. triallyl cyanurate, hydrolysable silanes e.g. vinyl triethoxy silane, or radiant energy e.g. using a Co-60 source or a beam of accelerated electrons. The cross-linking temp. is 180-280 degrees C and the deformation temp. for return to the original shape 110-170 degrees C. This deformation is accelerated by raising the pressure in the transport container by 100-500 Torr.

Title: Integrated-pivot safe-closing door or window - with rounded leaf outer edges and moulded lining and case block
Inventor: BERTZEN CLEMENS
IPC: E06B1/52
Filed: 1974-05-13
Abstract: The design is such that the leaf does not turn out of its frame rabbet in the process of closing, thereby incurring a danger of crushing fingers as its shuts. This is achieved by integrating the point of rotation in the door or window leaf. The outside edges of the leaf are rounded off, and there is moulding on the lining- and- case block or blind frame inside edges and integrated pivot. This gives optimal protection against finger crushing, inasmuch as no danger zone can be created by raising the covering from the leaf, while the rounding moves in a correspondingly negative rounded area. This form of construction is applicable to all doors, windows and traps, and it can be built into existing structures.

Title: Commutator machine for high output - employs mechanical and semiconductor commutation with built-in diodes
Inventor: FRIDMAN GEORGY NIKOLAEWITSCH
IPC: H02K13/14
Filed: 1974-12-27
Abstract: The output of commutator machines is enhanced by spark suppression at the brushes through means involving the addition of diodes in the brush-commutator-winding path. The adverse effect on the size of commutator brought about by this construction may be overcome by building the diodes into the commutator segments. Each segment comprises a conductor plate (1) to which the windings (2) are joined. Contact plates (3, 4) on each side are insulated from the conductor plate using typically a sheet material (5). Recesses are cut into the contact plates to take the diode pellets (7) of appropriate polarity, which made connection to the contact plate. The contact plate surfaces are arranged to come in line axially at the commutator surface to give a positive and a negative brush track.

Title: Four-pole filter chain with large signal to noise ratio - has gyrators and min. possible LC series resonant circuits and specified constants
Inventor: GOECKLER HEINZ DIPL ING
IPC: H03H11/08
Filed: 1975-02-01
Abstract: The four-pole filter chain consists of series and shunt capacitors and gyrator capacitive circuits with gyrators earthed on both sides. The number of LC series resonant circuits designed into the filter, using equivalence conditions, is kep as small as possible. The gyration constants are so chosen that the dependent voltage increases across each gyrator are equal to or less than the corresponding independent voltage increases. In designing a high pass filter, the elements forming one attenuation pole are coupled in such manner in a chain that the frequencies of the appropriate pole from filter input and output rapidly decrease in monotone manner, while increasing in a low pass filter design.

Title: Temperature controlled repeater system - for carrier frequency cable transmission line has equaliser with temperature controlled resistor
Inventor: BENZ PAUL DIPL ING
IPC: H04B3/04
Filed: 1975-04-15
Abstract: The equaliser compensates the attenuation variations in a cable to temperature fluctuations, owing to its termination by a temperature controlled resistor. The equaliser is a Bode equaliser whose temperature controlled resistor consists of PIN diodes which are connected in parallel in opposite senses. Their resistance depends on the output current of a differential amplifier which has a temperature sensitive resistor connected to one of inputs. This system is placed at a point which is at the same temperature as the cable. At a median temperature (To) the effect of the system is zero. At higher temperatures (To + AT) the higher frequencies of the signal are attenuated the higher frequencies are amplified.

Title: Watch dial having signs in relief - formed by anodising aluminium, stamping and exposing top surface
Inventor: MONTAVON DENIS
IPC: G04B19/10
Filed: 1975-04-26
Abstract: Dial, for a watch, having signs in relief, is produced by the use of an Al-based material which can be coated with an anodised layer for forming the dial and which is not yet provided with relief projections. The dial sheet surface is anodised and then stamped, to form relief elements which show the bare material on all side-faces of the elements. The adhesion and strength properties of the anodising layer ensure a straight crack-free separating line at foot of these side-faces between the surface of the anodised base and the bare side-faces. Anodised layer on top surfaces of the relief elements is removed to expose the bare material. Bare top surface and bare side-faces of relief elements is made use of to impart a specific appearance to the relief elements, giving the impression of real attached pieces set off from the remaining parts of the anodised dial surface. Cheap process imparts luxurious appearance of a dial with real attached pieces and allows patterning of dial surface, e.g. by marbling.

Title: Frame for non-hierarchical multiplexer - is for combination of digital TDM subsystem with different bit rates
Inventor: ASSMUS ULF DIPL ING
IPC: H04J3/07
Filed: 1975-06-20
Abstract: The subsystems are plesiochronously operated, and the bit rates cannot be derived from each other by division. Irrespective of the bit rate, spacing between two synchronous words (F) of 16 bits each is always 8 x k bits. After 4 x k bits, in the middle of the frame so produced, a time channel (S) of 8 bits is reserved for recognition of the timing matching signal of at the most two subsystems with relatively high bit rate. When subsystems with different and/or lower bit rates are used, six further equally spaced time channels of K bits each are provided, with different numbers of bits, depending on the number of subsystems to be combined.
