Patent DE-2822188-A1 (DE)
Title: Transport control of fibrillated cellulose for absorbent papers - is effected automatically dependent upon resistance to agitators
Inventor: HAEGG PER BOERJE
IPC: B65G43/08
Filed: 1978-05-20
Abstract: The amt. of dry, shredded or dry, fibrillised cellulosic material which, per interval of time, is to be transferred to and/or froma storage vessel provided with agitators, is controlled automatically. The control of the operation which includes the transfer of the material for further refinement, is effected depended upon the resistance of the material to the agitators. When this resistance is increased, the amt. of material fed in per unit of time, is reduced, and/or the amt. transferred from the storage vessel per unit of time is increased. In the event of reduced resistance to the agitators, the transfer operation is carried out in reverse. Provides an efficient, continuous and uniform feed of fibre to machines for diapers and similarly high absorbent products. The technique described here forms a much more accurate means of determining the amt. of material under agitation than photo-electric cells nd ultrasonic detectors.

Title: Twisting machine spool - has cladding on flange rim to give running surface for yarn
Inventor: WENDEL FRITZ
IPC: F02B1/04
Filed: 1978-07-21
Abstract: The rim is a seamless enclosed cladding around the head disc flange. The cladding is of a material with a higher surface quality, a higher notch hardness and a lower shrinkage. The design gives an optimum running surface for the twisted material to be wound on to the spool. The head disc of the spool is made of metal, to give the spool a one-piece construction with the shaft and a foot disc, with mounting inserts as special sections of the spool. The rim of the foot disc is clad with a material to give the same shape and characteristics as the cladding on the head disc. The cladding on the head disc is applied by injection moulding, or shrunk into place so that the disc and the cladding are keyed together.

Title: Solar reactor for chemical processes - with concentric spherical shells located in focus of solar rays
Inventor: MALBURG WERNER
IPC: F24S20/20
Filed: 1978-08-18
Abstract: A solar reactor for the use of focussed sunlight for water gas or methane processes or for coal gasification is located in the focus of a parabolic mirror. The rays enter through an opening in a spherical shell, permeable to radiation, which is surrounded by a concentric shell, impermeable to radiation. The space between them which contains baffles to enforce a swirling flow, receives the feedstock gas, if the rays enter from the 7 o'clock position, from a pipe in the 12 o'clock position, two cracked gas outlets, one with a dust taphole, are in the 9 and 3 o'clock position. This facilitates the assembly of the solar reactor in a parabolic mirror or in heliostat towers.

Title: Arc-shaped permanent magnet for small motor - has ends made narrower by using adjacent regions of high remanence and high coercive force
Inventor: CORBACH RAINER DIPL ING
IPC: H02K23/04
Filed: 1978-10-05
Abstract: The permanent magnet is arc-shaped with material of high remanence at one end (11) and material of high coercive force at the other end(12). The following equation is fulfilled:d0/d2 = 1 - (H2/H1)(1-d0/d1), where H1 and H2 are the limit field strengths of the high coercive force and the high remanence ends respectively, do is the thickness of the magnet at its centre, d2 is the thickness of the magnet at the boundary between the ends, and d1 is the thickness at the high coercive force end. The advantage lies in reducing the increase in thickness of the magnet towards its ends whilst preserving its resistance to demagnetisation by transverse armature fields. Narrower ends to the magnet ensures smaller stray magnetic fields.

Title: Diffusion alloyed electroplate with less brittle centre - of silicon alloy roll plated with aluminium and annealed after anodising or evapn., to reduce thickness
Inventor: BECH ULRICH DIPL ING
IPC: C23C10/00
Filed: 1978-12-29
Abstract: Diffusion-alloyed electroplate consists of Si-alloyed electroplate, pickled after hot rolling and roll plated with Al. Before diffusion, pt. of the Al coating is anodised to form a protective coating for high temp. annealing and reduce the metallic Al to the desired slight thickness. The anodised layer also acts as heat-resistance, electrical insulating layer, which must also be applied for the purpose of application of the electroplate. After cold rolling, the Al can be vaporised, so that anodisation is unnecessary in partic. in dry annealing furnaces. Redn. of the thickness of the Al layer ensures that the Al content is highest near the surface and lower in the centre, so that the middle of the strip remains less brittle, which improves the processability. This also favours magnetic flux.

Title: Crankshaft for reciprocating engine - has different bearing finish for shaft and piston rod locations
Inventor: KLUENDER KLAUS
IPC: F16C3/06
Filed: 1979-07-31
Abstract: The crankshaft (1) is used in an IC engine or air compressor. It has a different surface finish for the crankshaft bearings (2) and the piston rod bearings (3). The crankshaft bearings which have a lower radial load, have a ground surface finish of 0.2 microns.

Title: Carbon di:oxide determn. in gases - by measuring sound velocity
Inventor: BISSINGER ROLF
IPC: G01H5/00
Filed: 1980-03-13
Abstract: The carbon dioxide content of gases, specially of air, flue gases, respiratory air etc. is measured by determining across a section contg. the gas, the velocity of sound and by using this as a yardstick for the CO2 content. This velocity of sound is determined from the time required for a sonic pulse to travel across a measuring section or from wavelength and frequency. This method is convenient to apply and furnishes results of good precision.

Patent DE-3034720-A1 (DE)
Inventor: MUETZENBERG ARNOLD B DR ING
IPC: C02F11/18
Filed: 1980-09-15
Abstract: For the purpose of cooling a batch of a reaction mixture, e.g. fresh sludge of a sewage plant, the process employs a medium stored in two reservoirs (8, 11) and an additional reservoir (12). The medium of the first reservoir (8) is heated in the process to a first temperature, and the medium of the second reservoir (11) is heated to a second, lower temperature. The medium stored in these reservoirs (8, 11) is then utilised in heating a subsequent batch which may follow some considerable time after the previous one. During heating, the tanks (8, 11) are used in the reverse order. Therefore, the less hot medium from the reservoir (11) is used first, followed by the warmer medium from the reservoir (8). Heating of the batch is completed by delivering medium from the heatable additional reservoir (12) through the heat exchanger (3). The appliance has only one heat exchanger (3) which can be designed to be relatively small. The reaction mixture is circulated by the pump (2) in a circuit which consists of the reactor (1), the pump (2) and the heat exchanger (3). Analogously, the medium is also circulated by a pump (5) from a selected reservoir (8, 11, 12) to the heat exchanger (3) and back to the reservoir, valves (6, 7, 9, 10) being employed to select the reservoir required. <IMAGE>

Title: Information and power transmission system using one conductor pair - has filter for HF signal extraction and by=pass chokes for DC power supply
Inventor: TRETOW JOCHEN
IPC: H04B3/54
Filed: 1980-11-12
Abstract: The system provides for signal and power supply for the transmitter- receiver to be sent along one pair of wires. The object of the proposed circuit is to give improved separation between signal and power at the transmit-receive unit. The common input to the unit is passed through a rectifier and applied to.a transducer whose secondary winding feeds the filter through which the HF modulated signals from the transmit- receive stage are passed. The transducer is bypassed by two chokes for providing the dc power supply to the unit. A capacitor is connected across the power supply, and, in series with a resistor, also across the filter terminals on the transmit-receive side. The resistor may be shunted by a choke. The power supply input, connected to the leads joining up to the unit terminals is buffered by a choke to prevent HF signals being short circuited by the power source. The chokes have a high impedance relative to the input and output resistance of the signal unit. An application of the transmission system is to communications channels in mines.
