Patent DE-3400644-A1 (DE)
Title: Scraper, especially for double-scraper chain conveyors
Inventor: SCHEWINSKI HARTMUT
IPC: B65G19/22
Filed: 1984-01-11
Abstract: The invention relates to a scraper, which is intended especially for double-scraper chain conveyors with scraper chains which run on the outside in the conveying trough, and which consists of a V-shaped scraper profile section, the opening side of which faces the conveying floor. According to the invention, the scraper profile section is designed so as to be symmetrical relative to its longitudinal central plane, and to have a steep carrier surface on each of its two sides. An unordered heap can therefore be optionally conveyed in either direction in the conveying trough, with the aid of the scraper. The height of the V-shaped scraper profile section is preferably considerably greater than the maximum outside width of the profile section on the profile opening. A scraper profile section of this type yields a scraper which is sufficiently strong in conjunction with reduced weight.

Title: Device for regulating the working depth of seed coulters
Inventor: WALKE GEORG
IPC: A01C7/20
Filed: 1984-01-11
Abstract: It is known to adjust the working depth of seed coulters hydraulically. There is no readjustment in the event of a varying soil quality. Also known are devices which ensure that, when the seed drill is being lowered into the working position, the seed coulters are inserted with a delay, in order to prevent the seed coulters from being clogged with earth. 
<??>The object of the invention is to provide a continuous regulation of the working depth in combination with the control of the delayed application of the seed coulters. According to the invention, this is achieved by means of three electrical switch complexes which are switched in dependence on the travelling movement of the seed drill in relation to the tractor and on the position of a ground tracer in relation to the seed coulters.

Title: Measuring device for the ink remaining in a flexible ink bag in ink printers
Inventor: SICKING HEINRICH ING GRAD
IPC: B41J2/175
Filed: 1984-03-07
Abstract: In order to avoid faults such as the occlusion of air in the ink supply system, interruption of the printing process etc. which can be initiated by the replaceable protective container (21) with in each case an ink bag (36) becoming empty in ink printers, constant monitoring of the ink supply in the ink bags (36) is required. The invention is based on the object of providing a measuring device for the residual ink in reservoir containers (21), which is simple, robust, functionally reliable and inexpensive. This object is achieved by means of a detector device (16) consisting of an optical transmitter (17) and an optical receiver (18), the light transmitted by the said detector device (16) being capable of being guided through transparent walls of the protective container (21) and of the ink bag (36) and through the ink chamber. The optical receiver (18) receives the light which penetrates the ink chamber and emits an output signal which is dependent on its intensity. As a result, a reliable indication of ink in the ink bag (36) is ensured and an optimum utilisation of the ink supply in the ink chamber of the ink bag (36) is achieved. <IMAGE>

Title: Sampling valve for a coal gasification plant comprising a flue-dust or fluidised-bed pressure reactor
Inventor: RICHTER ARTUR ING GRAD
IPC: C10J3/72
Filed: 1984-06-22
Abstract: The invention relates to a sampling valve for a coal gasification plant comprising a flue-dust or fluidised-bed pressure reactor, the sampling valve being used to take a liquid or gaseous sample from the crude gas discharged at high temperature. In order to be able to control the operating conditions in an optimum manner, it must be possible to determine the composition of the crude gas at a position as close as possible to the reactor outlet, notwithstanding the high temperature and any high condensable solid content at this point. In order to make sure that this is possible, the sampling valve is to have a heating appliance and/or a flush-cleaning arrangement, the heating counteracting condensation and the flush-cleaning arrangement serving to remove any condensation components which may arise nevertheless.
Patent DE-3423746-A1 (DE)
Title: Heat exchanger laminar for tubes with an elliptical or oval cross-section
Inventor: THOMAE RUDOLF DIPL ING
IPC: F28F1/32
Filed: 1984-06-28
Abstract: The invention relates to a heat exchanger laminar for tubes with an elliptical or oval cross-section. It is very difficult here to form from the surface of the laminar - as is generally the case for round tubes - collars around the openings for the heat exchanger tubes which for the purpose of preserving a specific laminar spacing have a further circumferential rim bent at a right angle. In the case of elliptical or oval tubes, it is possible to integrally form an angular rim, running round 90 DEG , for fixing the laminar spacing at the collars only by accepting a jagged rim on the narrow sides of the ellipses or ovals. The heat exchanger laminar in accordance with the invention avoids these disadvantages owing to the fact that the openings for the tubes in the laminar are constructed in such a way that the rim of the circumferential collar is angled by 90 DEG  again only in the regions of the ellipses or ovals which have the large radii of curvature. In the regions of the small radii of curvature, the collar height is substantially reduced. <IMAGE>

Each door (7, 8) comprises two lateral shaped wire elements (14, 15 or 16, 17 respectively) which are connected to one another via two or more connecting rods (22, 23 or 24, 25 respectively). <IMAGE>
Patent DE-3431517-A1 (DE)
IPC: G01L21/24
Filed: 1984-08-28
Abstract: For measurement of gas pressure a gas-friction vacuum meter is used in whose measuring head a rotating body is suspended in a magnetic field contact-free between electromagnetic drive coils. The rotating body is set in motion with the aid of the drive coils and maintained at a rotational speed above a preset minimum rotational speed. The speed reduction of the rotating body occurring on account of gas friction is continually or intermittently balanced with current flows from a three-phase generator to the drive coils. In the measuring head rotational speed sensors are arranged and positioned, which detect and respond to the rotational frequency of the rotating body, and further transmit output signals to an electronic analyzer unit, which determines the pressure from the timely change of the rotation frequency. In order to increase the pressure range for which the apparatus may be accurately used further, the analyzer unit receives a temperature signal, which correlates with the temperature of the gas surrounding the rotational body, in such a way, that the pressure measurement is corrected for the influence of heat transferred to the gas during operation of the rotating body.

Title: Translational reversing drive for machine tools
Inventor: BOHRING HORST-DIETER DIPL ING
IPC: B23Q5/033
Filed: 1984-10-22
Abstract: The invention relates to a translational reversing drive for machine tools, which directly or indirectly drives a tool carrier by means of a motor-driven lifting mechanism, the stroke size being adjustable by means of a crank adjustment. The aim of the invention is to increase the work productivity by higher numbers of double strokes, along with the same maximum speed, and, together with eliminating the machine standstill times for the adjustment of the stroke size, to increase the serviceability. According to the object, the adjustment of the stroke size is carried out in an automated manner during the machining operation, so that, integrated in the control, a continuous adaptation to the tool engagement line takes place and the speed trend is influenced via the crank travel. According to the invention, the adjustment of the crank pin takes place by means of a hydraulic motor connected to a control circuit, of which the desired-value transmitter and the actual-value transmitter adjustable from the position of the crank pin control a comparator element which is connected via an operational amplifier to a servovalve. Furthermore, a stroke-speed desired-value sub-assembly synchronised with the bearing pin is connected to the comparator element in a way capable of being cut in. <IMAGE>

Title: Low-noise outlet piece with limited and laminar throughflow
Inventor: NELSON WALTER R
IPC: E03C1/08
Filed: 1985-08-16
Abstract: An outlet piece of a tap is described. It comprises a plate (30) which bounds the throughflow and has apertures (32, 36) which bound the throughflow. One aperture (36) is arranged in the centre and adjusts the throughflow because the diameter of this adjusting aperture (36) has been selected such that the overall throughflow volume of the device is within a particular range of throughflow volumes, specifically just at the lower boundary of the range such that the noise generated by the throughflow remains at a minimum. The outlet piece also comprises alternating rows of perforated discs (44-46) and of wire sieves (40-43, 47-49) in order to reduce the speed and to distribute it evenly over the cross-section in order to obtain a laminar flow. 
<??>One sieve is in direct contact with the downstream surface of the plate bounding the throughflow, as a result of which the noise is reduced even further.
