Title: Sensing resistor for high direct currents
Inventor: STEIGLEDER BODO ING GRAD
IPC: G01R1/20
Filed: 1982-10-09
Abstract: The invention relates to a sensing resistor (3) for high direct currents, across which a direct voltage is picked up and which exhibits oppositely located areas (11, 12) which are used for establishing electric contact with current-conducting elements (1, 2); such resistors are used for sensing the welding current in so-called rectifier-type welding machines. The sensing resistor is arranged, for example, between the upper clamping plate and a flexible current strip; it has two taps for the sensing voltage. The sensing includes the tightening torque with which the sensing resistor is clamped and also contact resistances which change due to the area pressure so that sensing errors can occur. This is prevented by providing the sensing resistor (3) with several taps (13', 14') for the direct voltage, which are brought together (15', 16', 15", 16"), Figure 4. <IMAGE>
Patent DE-3240529-A1 (DE)
Title: Separable magnetic conductor of an electrical machine, and a method for its production
Inventor: GUSEV BORIS JAKOVLEVIC
IPC: H02K1/18
Filed: 1982-11-03
Abstract: The invention relates to electrical machines having magnetic conductors which are produced using technologies which produce no waste. The separable magnetic conductor of the electrical machine contains a yoke (1) and a tooth zone (3) which is formed by a corrugated strip (4). The height of the tooth zone (3) is equal to the width of the corrugated strip (4). The edges (7, 9) of the corrugated strip (4) face the operating air gap (8) and the yoke (1) respectively. Each tooth (10) of the tooth zone (3) is produced from at least two layers of corrugated strip (4), while the transitions (11) which connect the teeth (10) are produced from uninterrupted flat material which represents a continuation of the corrugated strip (4). The invention can be used in the construction of electrical machines.   <IMAGE>
Patent DE-3244003-A1 (DE)
Title: Compressor
Inventor: ROWALD DIETER
IPC: F04B39/10
Filed: 1982-11-27
Abstract: The compressor designed especially as a piston compressor has an intake valve comprising aperture (12), valve seat (14) and leaf spring (13), which is so designed and arranged that at rest it does not bear on the valve seat but stops somewhat short of this. As a result, when the compressor is switched off and the speed of the drive motor is thereby falling, the force acting on the intake valve during the compression stroke is no longer sufficient to completely close the valve gap, as a result of which the compression work is greatly reduced. This consequently results in prolonged, unloaded turning of the rotor of the electric motor and hence in a sharp reduction in the deflection of the compressor as it passes through the critical speed. In this way unwanted noise is prevented. <IMAGE>

Title: Method for measuring the valve play of combustion engines with overhead camshaft and bucket tappets and measuring instrument for performing the method
Inventor: STUERTZ PETER
IPC: F01L1/20
Filed: 1983-04-22
Abstract: In this method, with the camshaft removed, the minimum distance between the camshaft bearing and the bucket tappet is first measured for each valve as an initial interim result. The minimum distance between the seat for the camshaft bearing and the base circle of the cams is then measured on the camshaft as a second interim result. The prescribed valve play is added to this to form the third interim result. The second interim result is then subtracted from the first interim result for each valve, giving the thickness of each valve setting platelet.
Patent DE-3315494-A1 (DE)
Title: Dough dividing and kneading machine
Inventor: SCHROEDER REINHARD
IPC: A21C5/04
Filed: 1983-04-28
Abstract: There is a dough dividing and kneading machine in which a supporting body (1) forms the reception device for chambers (3) which are each used for one piece of dough, which is open on its side facing the base (5) and is covered by a kneading body (12) and in which the supporting body and the kneading body can be driven in relation to one another to produce a kneading movement. It is desired that the kneaded bodies produced by the machine should be rounder, smaller at the end of kneading and softer at the centre. This is achieved by making the base (5) of the chamber (3) form a central shallow trough (14) which extends over at least a quarter of the horizontal base surface. The trough or dome-like recess in the base of the chamber, whose surface is as a rule smooth and without grooves, produces a rounder kneaded body, the surface of which is smaller after kneading and the centre of which is softer. <IMAGE>

Title: Pressure-reducing device for solids-containing liquids under a high pressure
Inventor: BEPPU KOHICHI
IPC: B01J3/02
Filed: 1983-07-22
Abstract: A pressure-reducing device for liquids which are under a high pressure and contain solid particles is disclosed. The device comprises a pressure-reducing column for gas and liquid with a gas phase region and a liquid phase region, a separation column for gas under a high pressure and liquid with a gas phase region which is connected to the gas phase region of the pressure-reducing column via a first line provided with an inlet valve and outlet valve for gas under a high pressure; it also has a liquid phase region which is connected to the liquid phase region of the pressure-reducing column via a second line having an inlet valve for liquid whose pressure is to be reduced. The device also has a separation column for gas under a low pressure and liquid with a gas phase region which is connected to the gas phase region of the pressure-reducing column via a third line having an inlet and outlet valve for gas under a low pressure, and having a liquid phase region which is connected to the liquid phase region of the pressure-reducing column via a fourth line with a valve through which pressure-reduced liquid is discharged. Before the inlet valve or the outlet valve for pressure-reduced liquid is opened, the inlet valve or outlet valve for gas under high pressure or the inlet valve or outlet valve, respectively, for gas under low pressure is opened, so that an increase or decrease of the pressure in a corresponding separation column takes place.

Patent DE-3331552-A1 (DE)
Title: Optical one-way distance-measuring method
Inventor: WOLF HENNING DR ING
IPC: G01B11/02
Filed: 1983-09-01
Abstract: The object of the invention is the contactless measurement of the distance from a surface. The invention consists of an arrangement which projects a light mark onto the surface of the test piece and determines the object distance of this mark (= distance from the test piece) by estimating the image distance. The advantage of this measuring method is that it permits measurement of the distance from an object surface without requiring optical quality for this surface. All that is required is a diffuse component of the reflection. Shading occurs only to a very slight degree, specifically in the region of the aperture angle of the illuminating optics. The influence of the orientation of possible obstacles or defects is slight, because of the largely rotationally symmetrical arrangement. Furthermore, the optical method permits sensitive, easily deformable parts to be touched and measured at a higher speed than in the case of mechanical measuring touch probes (because of the lack of inertial masses).

Patent DE-3340456-A1 (DE)
Title: Harrow
Inventor: BACKHAUS JOSEF
IPC: A01B19/06
Filed: 1983-11-09
Abstract: The invention relates to a harrow having stationary crossmembers and two movable harrow bars which are arranged parallel to these and which are respectively driven to oscillate in opposite directions. Such harrows are known on large tractors, but the outlay involved in also making it possible to use them on single-axle tractors is too high. Moreover, they have to be carried in their vertical position by the large tractor, a single-axle tractor being incapable of this because of its design. The invention makes it possible to use such a harrow for single-axle tractors, in that one harrow bar has means for coupling to the output element of an oscillating drive, to generate a to-and-fro movement of this harrow bar taking place essentially transversely to the direction of advance, this movement being transmitted in the respective opposite direction to the second harrow bar by means of parallel levers, these parallel levers being respectively mounted between their ends pivotably on the crossmember and with their ends pivotably on the harrow bars, whilst the stationary crossmember has fastening means for fastening to a housing of the oscillating drive and/or to supporting means of the single-axle tractor, is made smooth on its underside and can be brought into contact with the ground to be worked.

Title: Monitoring circuit for computers
Inventor: HOSAKA AKIO
IPC: G06F11/00
Filed: 1983-12-19
Abstract: A watchdog timer operates in dependence on special computer program characteristics in order to monitor the execution of the program and to reset the computer in the case of malfunction. The computer CPU (20) is programmed in such a manner that it periodically outputs one of two different data values to a register (60) which stores the data value for comparison in a comparator (70). The output value is compared with a predetermined value which corresponds to one of the two alternating values. When the two values compared with one another agree, the comparator (70) outputs a reset signal to a counter (80) which counts clock pulses. If it counts up to its capacity before it is reset by the output signal from the comparator, it outputs a reset signal which leads to the computer recommencing the execution of the program. A second comparator can be present for comparing the alternating data values with a reference value which corresponds to the second data value. The two comparators thus check the correct output of both signals and only reset the counter when both values are obtained. A second counting system can also be present which resets the computer both when the period of the alternatingly emitted values increases and when the period decreases. <IMAGE>

Title: Device for mixing multi-component plastics, in particular polyurethane
Inventor: WALLNER JOSEF
IPC: B29B7/76
Filed: 1984-05-18
Abstract: The device for mixing multi-component plastics, in particular polyurethane, is provided with a cleaning piston 2 of uniform cross-section which is movable reciprocally in the mixing chamber 1 and can be advanced from a position freeing the inlet openings 3 and 4 for the plastics components as far as the region of the outlet opening 9 of the mixing chamber. A throttle element consisting of two parts 5 and 6 projects below the inlet openings into the mixing chamber. An opening 10 formed by two semicircular depressions 7, 8, one in each face surface, is formed in the face surfaces of this throttle element. The two parts 5, 6 of the throttle element can be rotated independently of one another, so that, correspondingly, the semicircular depressions 7, 8 rotate with respect to one another and provide a more or less intense throttling, and therefore turbulence, of the mixture of components on its route to the outlet opening 9. The fact that the two parts 5, 6 can be independently rotated permits broad adaptation to a wide variety of components and requirements regarding the final product to be produced.

Title: Coacervation process for preparing aqueous dispersions of oil-containing microcapsules, and part of an apparatus for carrying out this process
IPC: B01J13/10
Filed: 1984-06-29
Abstract: A coacervation process is described for preparing an aqueous dispersion of oil-containing microcapsules, especially for chemical colour reaction papers, gelatine having an isoelectric point of at least 7.5 being used in the usual manner together with one or more hydrophilic colloids, which can be coacervated therewith and which can be charged in the opposite sense thereto, to form an initially liquid coacervate envelope around the oil droplets, and the liquid coacervate envelope being solidified by cooling and optional further measures, after the formation of the liquid coacervate envelope at a temperature of above approximately 43 DEG C, in a first step, in order to achieve controlled deposition of further coacervate as envelope material, a slow cool-down of the system to below approximately 22 DEG C being carried out under substantially turbulent conditions, and then, in a second step, more rapid cool-down being effected to a temperature resulting in the definitive solidification of the coacervate envelope. This process can be carried out economically and does not show the drawback of bunching of the capsules in the capsule dispersion. At the same time, an apparatus is described for carrying out the abovementioned first process step (Figure 1). <IMAGE>

Title: Circuit arrangement for a small PBX system
Inventor: FAHRENSCHON FRANZ DIPL ING
IPC: H04Q1/28
Filed: 1984-08-23
Abstract: The DC voltage required in each case for the electronic units and electromechanical components is derived from the AC mains voltage (Un). In the event of mains power failure while an exchange connection is set up for an extension, this extension is connected directly to the exchange line (AL), bypassing the exchange circuit. The subscriber station concerned is therefore powered in a case such as this from the exchange loop. The actuated switching elements retain their adopted switching position (contacts of a bistable switching relay). A switching means (ZU) which is shared by the connected stations and which indirectly effects the connection to the exchange line (AL) is powered in the event of mains power failure by a miniature battery (NC) until the end of the respective call. The variable exchange line changeover is then cancelled and the exchange line is switched to a pre-defined connected station should the mains voltage failure persist. Once mains power has been restored, the exchange line changeover is cancelled only when no further exchange connection remains set up. A 5-volt miniature battery which is no larger than conventional components and which can be accommodated without difficulty on a printed circuit board suffices to hold an exchange connection which is still set up during mains power failure. The miniature battery is recharged in normal operation from the operating voltage. <IMAGE>

Title: Process for producing ammonia synthesis gas
Inventor: REHDER REIMAR DIPL ING
IPC: C01B3/02
Filed: 1984-11-26
Abstract: A process is described for producing ammonia synthesis gas in which low molecular-weight hydrocarbons are subjected to steam reforming in a reformer. It is proposed to admix the reformed gas flowing out after steam-reforming with a nitrogen-containing gas following a CO shift conversion and to feed the mixture, after removal of CO2 and remaining CO, to an ammonia synthesis. The nitrogen to be admixed is preferably extracted from the flue gas produced in heating the reformer. The process is also suitable for the simultaneous production of ammonia synthesis gas and methanol synthesis gas.
