Title: Damping and filtering element for the ink supply to an ink jet print head
Inventor: ROSENTHAL MANFRED
IPC: B41J2/175
Filed: 1985-07-19
Abstract: The invention relates to a damping and filtering element for the ink supply to an ink jet print head, having a bottom part which has a shallow tray which is covered by a filter sheet and into which ink is conducted through the filter sheet, said ink being supplied to the ink jet print head via a suction aperture, and having an air space which is adjacent to the tray, is separated therefrom by a flexible wall, and communicates with the atmosphere through an aperture which leads through an upper part which surrounds the air space and is attached to the bottom part. A reliable design which is simple to assemble and consists of few uncomplicated components results from the fact that the air space is formed by a depression which is moulded into the upper part and is covered relative to the filter sheet by a flexible film, that the flexible film is clamped between edge surfaces of the bottom part and of the upper part, and that the ink supply duct into the space between the filter sheet and the flexible film projects perpendicularly through one of the two. <IMAGE>
Patent DE-3533236-A1 (DE)
Title: Portioning device, in particular for doughy media
Inventor: SCHNELL KARL
IPC: G01F11/02
Filed: 1985-09-18
Abstract: In a device housing (1), a rotary member (3) is rotatable about an axis (40). It has two internally closed longitudinal grooves (22 and 23), in which in each case a piston (5 and 6) is mounted displaceably in the direction of the axis (40). The grooves on the one hand and the cylindrical inner casing (21) of the housing (1) on the other hand form in each case a piston/cylinder space (11) or (12). The lower end of each of these piston/cylinder spaces is assigned in a quite definite rotary position to the housing inlet (7) on the one hand and the outlet (8) on the other hand. The ends of the pistons (5 and 6) facing away from the inner groove end (24) bear, in particular by means of a roll (14) and (15), against a support surface (13), the inclined position of which can be modified by means of an actuator (31). In the upward movement of the piston (5 and 6), the medium enters the piston/cylinder space (11) situated below the piston and it is pressed out of the device via the outlet (8) in the course of a 180 DEG rotation. During this 180 DEG  rotation, the piston is, at maximum portion size, displaced into its lower end position, at the end of this displacement movement the piston/cylinder space (12) having been reduced to a minimum size which theoretically can come at least close to the zero value. It may not, however, reach the zero value as a gap is necessary in order that the pressurised medium can flow into the latter. The piston is then pressed upwards towards the support surface. <IMAGE>

Title: Break point indicating device
Inventor: EDERHOF ALFRIED DR
IPC: G01N1/20
Filed: 1985-10-14
Abstract: A measuring device for ensuring a pure liquid flow during the extraction of samples from two-phase flows consists essentially of a housing (17) arranged perpendicularly in a measuring line and a float (18). When water and steam flow in, the float (18) sinks owing to the lower density then prevailing in the housing interior. It seals the outflow, thereby fixing the so-called break point. The measuring device is suitable, in particular, as a preparatory measure for tracer measurements of water flows in steam power plants. <IMAGE>

Patent DE-3628491-A1 (DE)
Inventor: MERZ KARL
IPC: B21D11/12
Filed: 1986-08-22
Abstract: The machine serves for the bending and bundling of connecting baskets. It has an apparatus for feeding special meshes to a bending and bundling station. The bending and bundling station forms a working unit, in which the special mesh (23) to be bent runs through a first bundling phase during bending and, immediately after completion of the bending operation, undergoes the final phase of bundling. Two bending elements (30) and a plurality of receiving elements (10) are provided for the connecting baskets. During bending and bundling of the connecting baskets, a receiving element (10) is stationed underneath the bending elements (30) in such a way that after the bending operation the connecting basket in each case straddles the receiving element (10) and the free ends of the bent-around limbs of the basket lie in the region of or underneath the receiving element (10). This machine makes it possible not only to bend connecting baskets fully automatically from appropriate special meshes but also to bundle them fully automatically, i.e. to produce corresponding stacks of connecting baskets. <IMAGE>
Patent DE-3631587-A1 (DE)
Title: Method for calibrating multi-channel direction finders
Inventor: JONDRAL FRIEDRICH DR
IPC: G01S3/74
Filed: 1986-09-17
Abstract: In order to calibrate a multi-channel direction finder having in each case one analog input section and one subsequent digital signal path in each channel, an analog calibration signal is passed to all the channels in a calibration phase. The digital calibration signals occurring in consequence in the digital signal path are frequency-analysed separately for each channel, by means of Fourier transformation. The errors in the transfer functions are determined by forming the difference between the spectra of all the channels and a channel which is selected as the reference channel. In direction-finding operation, the digital signals in all the channels are subjected to Fourier transformation and, with the exception of the reference channel, are subsequently corrected in correction elements whose parameters are formed by the differences formed in the calibration phase. In the reference channel, the signals are delayed by a time which is equal to the delay time in the correction elements. The signals in all the channels are subsequently transformed back into the time domain by means of inverse Fourier transformation, and are passed on for direction-finding evaluation.

Title: Method and device for fitting solder rings onto pins
Inventor: KRUMM MANFRED
IPC: H01R43/048
Filed: 1986-09-30
Abstract: Contact pins for printed circuit boards are provided with solder rings (Lr) whose volume corresponds to the quantities of solder required for soldering the pins (St) into the holes in the printed circuit board. For this purpose, a section of a piece of solder (L) in the form of a wire or strip is pressed by means of a holding-down device (Nh) against the respective pin (St) and is initially bent in a U-shape around the pin (St) by operating two bending stamps (Bs1, Bs2). After this, the side webs of the U-shaped solder part which still project are pressed against the pin, by operating two contact-pressure stamps (As1, As2), in order to form a solder ring (Lr) which is at least approximately closed. Even in the case of pins (St) having a sensitive gold coating, no damage occurs when this procedure is used. In addition, extremely short cycle times can be utilised. <IMAGE>
Patent DE-3639061-A1 (DE)
Title: Process and apparatuses for producing boards made of wood-based material
IPC: B27N3/08
Filed: 1986-11-14
Abstract: The invention relates to a process for producing boards made of wood-based material, in which particles of wood-based material are coated with a hardener-free binder, subsequently scattered to form a mat and are then pressed. During the compaction phase, an acidic or basic hardener in the gaseous phase or in a binary phase with a gaseous carrier agent is fed over the surface of the mat and/or directly into the interior of the mat in the press. The apparatuses implementing this process operate either with a continuous double-belt press or a discontinuous single-daylight or multi-daylight press. The double-belt press has two pressing belt arrangements, on the inner side of which the hardener is passed via feeds in the wedge-shaped run-in zone. In the pressing belt arrangement, openings reaching to the outer side are provided, through which the hardener passes onto the surfaces of the mat. Provided in the pressing plates of the discontinuous presses are bores for feeding the acidic or basic hardener, from which bores vertical openings lead off to the pressing-plate surfaces facing the mat.
Patent DE-3641614-A1 (DE)
Title: Medical equipment combination for bandaging materials and cellulose swabs on rolls
Inventor: ZANKER HELMUT
IPC: A61F15/00
Filed: 1986-12-05
Abstract: Based on the present state of knowledge, the dispensers for swab and bandaging material rolls that have been conventional in clinics and medical practices for many years no longer meet the hygienic requirements according to which microbial contamination of the roll remaining in the equipment must be avoided after removal of a swab or roll section. This requirement is fulfilled by a novel dispenser in which the actual storage space for the roll is no longer accessible directly for removal of material but is substantially sealed against penetration of the outside air by a kind of sluice. In order to carry out the routine work, that is required in everyday practice at various workplaces, as independently of the fixed wall cabinets as possible and in a manner that is even more economical than hitherto it is moreover proposed that the said dispenser be combined with a liquid dispenser and a fitting console, so that a small equipment combination with the requisite utensils for withdrawal of blood and injection is available directly at the particular workplace. The attached figure illustrates the combination of a table console with a removable dispenser which can selectively be used for swabs or bandaging material. The simple mounting permits several dispensers of the same type to be arranged next to one another in any order, depending on the size of the console, so that individual combinations are possible for each workplace. <IMAGE>

Title: Actuating device for the axially displaceable spindle of a hand-operated regulating valve
Inventor: TROIKE KARL-HEINZ
IPC: F16K31/60
Filed: 1987-01-15
Abstract: The actuating device for the axially displaceable spindle of a hand-operated regulating valve consists of a sleeve which can be screwed onto the valve body and of a hand cap surrounding the sleeve, this cap being screwed onto the sleeve by means of a thread. Formed integrally on the end surface of the hand cap is a pin, the end face of which acts on the valve spindle of the hand-operated regulating valve. Formed integrally on the pin are spring arms which point towards the end surface of the hand cap and, when the cap is screwed on, engage behind a radially inward-projecting rim on the sleeve. This rim on the sleeve forms the stop surface during the opening of the valve. During the closure of the valve, the stop is formed by the end face of the sleeve and by the end surface of the cap.
