Title: Arrangement for determining the position and movement of objects
Inventor: KERSTEN PETER DR ING
IPC: G01P3/488
Filed: 1987-02-14
Abstract: The invention relates to a position transmitter (1) which has a magnetisable device (2) with ferromagnetic, low-retentivity strips (5) which are arranged parallel to one another, a magnetic field sensor (3) with a magnetic-field-dependent resistor (6) and a device for producing an alternating magnetic field (30). The device for producing an alternating magnetic field (30) has a yoke (10) and, by virtue of the periodic structure of the magnetisable device (2) produces a spatially periodic stray field between the two outer yoke legs (11) and (12), which stray field serves to determine the relative position between magnetic field sensor (3) and magnetisable device (2). The alternating field brings about a magnetic modulation of the magnetic field sensor (3). In order to compensate magnetic interference fields, the magnetic-field-dependent resistor (6) can be complemented with an appropriately arranged conductor track through which current flows. The arrangement can also be constructed as a speed-of-revolution sensor and be designed to determine an angle of rotation. <IMAGE>

Abstract: A circular-disc-shaped body, in particular a metal wool pad made of fibrous material matting together, consists of an axially compressed circular-disc-shaped layered body whose layers are spirally wound-up plies of fibre strands. Said circular-disc-shaped body, which is intended preferably as a grinding and/or polishing disc, consists of a fibre tube which is formed from fibre strands wound up on a winding spindle, is pressed flat and is rolled up in the manner of a spiral. The resulting circular cylinder is then axially compressed, thereby producing a matting of the mutually adjacent fibre strands. According to a second manufacturing method, the fibrous material is wound up on a winding spindle in the form of fibre strands in a helical multi-stranded arrangement next to one another and spirally in a plurality of layers above one another and is then likewise axially compressed.
Patent DE-3721948-A1 (DE)
Title: Method and apparatus for uniform distribution of pneumatic conveying currents
Inventor: BRANDAUER OTTO
IPC: B65G53/52
Filed: 1987-07-03
Abstract: In conveying a mixture of air and solid material, a defined mixture of solid material per unit time must be fed in a continuous form to a process. The distributor elements used for this purpose must be installed in the vertical conveying line, the distance from the deflection hitherto having to have been selected so as to be very large in order to achieve a uniform distribution. In a method for uniform distribution, the conveying current is introduced, via a horizontal conveying line, into the deflection element, made turbulent there, and subsequently a distributed mixture of air and solid material is fed to the distributor element. In one distributor arrangement, a deflection element for 90 degree deflection is used, which has a hollow-cylindrical deflection chamber (26) having inlet and outlet connection pieces (16, 17) arranged on the circumference, the outlet connection piece being arranged in the radial direction and the inlet connection piece being arranged almost tangentially. The deflection element has, furthermore, a radius of curvature between the inlet connection piece and the outlet connection piece which corresponds to one to two times the diameter of the line, and a lining of the inner surface, which consists of rubber. Distribution of pneumatically conveyed materials, in particular calcium hydroxide.

Title: Suction bottle for aspiration of wound discharge
Inventor: FELL HELMUT DR RER NAT
IPC: A61M1/00
Filed: 1987-07-24
Abstract: A suction bottle (11) for aspiration of wound discharge contains a small amount of a pressure-adjusting liquid (16) which is chosen such that its vapour pressure corresponds to the desired suction vacuum. This measure has the advantage that the suction vacuum is maintained up to almost the complete filling level of the suction bottle or even decreases, specifically when the liquid is chosen such that it dissolves in the aspirated discharge. Moreover, the suction vacuum can be varied by changes of the temperature. The bottle may have thinner walls than previous bottles because the risk of deformation during sterilisation owing to the increasing internal pressure with increasing temperature is lower than in conventional bottles. <IMAGE>

Title: Selective cut heading machine
Inventor: SCHOLTYSEK HEINRICH
IPC: E02F9/22
Filed: 1987-12-24
Abstract: The known concept of the drive of the swivelling and cutting drive of selective cut heading machines, in which the cutting-head drive resulted via an electric motor and the swivelling drive resulted hydraulically, the hydraulic power fed to the swivelling drive being reduced, when necessary, for the purpose of avoiding overloading of the cutting motor, has the disadvantage that the power installed in the region of the hydraulic system is utilised only incompletely as a function of the rock condition, as a result of which the energetic total efficiency of the selective cut heading machine is released. In a selective cut heading machine according to the invention, the electric motor (19) of the swivelling drive is assigned a hydraulic motor (18) which can be controlled in terms of power and via which, when necessary, a part of the hydraulic power, taken from the swivelling drive, is fed to the cutting drive so that the hydraulic system belonging to the machine can be operated with essentially constant power which is only distributed, according to the respectively encountered rock conditions, to different consumers, namely the cutting drive or the swivelling drive. <IMAGE>

Patent DE-3815828-A1 (DE)
Inventor: CHANDLEY GEORGE D
IPC: B22D18/04
Filed: 1988-05-09
Abstract: Countergravity casting of molten metal with exclusion of air in a gas-pervious mold (20) sealed in an evacuable chamber (12) having a free end of a fill pipe (40) for the mold cavities (26) projecting 26 therefrom. The fill pipe is moved relative to an enclosed crucible (62) containing the molten metal under an air-free atmosphere of inert gas to project the fill pipe free end through an opening (74) in the crucible enclosure (60) to a position below the molten metal surface (64) so that evacuation of the chamber (12) produces filling of the mold. Entry of air into the crucible enclosure (60) through its opening (74) is prevented by maintaining the surface (64) of the molten metal and the ambient atmosphere a sufficient distance apart prior to insertion of the fill pipe (40) to prevent circulating air currents from drawing air through the opening (74) down to the metal. Entry of air can be further prevented by maintaining a sufficient pressure of inert gas in the crucible enclosure and by sealing the upper portion of the fill pipe between the chamber and the mold. In one embodiment a collapsible shield (89) is provided between the opening (74) and chamber (12). In another embodiment (Figs. 3 & 4, not shown) the enclosure (60) has an extensible cover (66). A special cover arrangement may be provided for the enclosure (60) during an ingot melting phase (Fig, 5, not shown). <IMAGE>

Inventor: KIRSCHENSTEIN REINHARD
IPC: H04N5/06
Filed: 1988-10-08
Abstract: A method for producing a three-level pulse signal comprises providing a tristate gate 1 and a voltage divider 2, 3 connected between an operating potential +Ub and a reference potential, the tristate gate having a signal input 5, a control input 4 and a signal output 6 with the signal output being connected to the tap of the voltage divider. The method comprises providing first and second binary pulse signals b and c as control and input signals respectively to the tristate gate to produce the said three-level pulse signal a at the tap of the voltage divider, the tristate gate being transmissive of the input signal c when the control signal b is low and non-transmissive when the control signal b is high. Thus the three-level pulse signal is at a first level corresponding to the low level of the input signal c when both the control and input signals b and c are low, at a second level corresponding to the high level of the input signal c when the control signal b is low and the input signal c is high. and at an intermediate third level corresponding to the potential at the tap of the voltage divider when the control signal b is high. <IMAGE>

Filed: 1988-10-19
Abstract: In a space divider element (1), cold-rolled sections made of sheet metal are envisaged as section supports (2) and cross-members (3), the flange plates (16), which serve for the suspension of the space divider plates (8) via suspension connections (10), of the section supports (2) being fastened to the one-piece section cross-piece (17) lying in between via one-piece form-fit members (30) which are formed in such a manner by means of bending tongues (31), which are punched out of the flange plates (16) and engage through punched openings, that the tongue bends of these bending tongues (31) form the lower limits of suspension openings for the mountings to be inserted through the plate joints (11). The cross-members (3) are designed practically identically in cross-section to the flange plates (16) and fastened in such a manner via cross-member connectors (13) inserted from outside that two cross-members (3), which lie opposite one another at a distance, form a cross-member connection and, between them and over the entire height of the section supports (2), a continuous insulation (9) can be provided. The suspension connections (10) are designed in such a manner that the space divider plates (8) are drawn with their inner sides against lips of joint seals (15) which are designed in one-piece with a joint cover (14), lying behind the respective joint (11), for the section support (2). The joint cover (14) can be broken through, by means of the respective mounting and with formation of lip seals, in the region of a predetermined breaking line in order to make accessible the suspension openings lying behind. Consequently, a particularly good heat-insulating and sound-insulating as well as stable mobile space divider is produced with simple construction, light weight and good mountability. <IMAGE>

Title: Control of a winding shaft in a lifting-roller retractor
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/36
Filed: 1989-03-14
Abstract: A description is given of a control of a winding shaft in a so-called second-generation lifting-roller retractor. The movement sequence of the plate cam, during the transfer of the winding shaft 1 from the rest postion into the blocking position is divided into two parts. The first control movement after the activation of the sensor, which couples the plate cam 16 and winding shaft 1 to one another, is a common rotation about the point M through the angle  beta  (during which a pilot-control ratchet 2 can pivot into the shaft toothing arrangement 3) and then a common pivoting movement about the pivot-point axis S' through the angle  gamma , this been effected, on the mechanism side, by the plate cam 16 and, on the spring side, by a pivot lever which is identically mounted in this phase. This control sequence which is predetermined by the design gives rise to double synchronisation in series, as a result of which the safety of the precise blocking activation of the winding shaft is improved. <IMAGE>

Abstract: The present invention relates to a novel sizing composition in the form of an aqueous emulsion comprising a hydrophobic cellulose reactive sizing agent and a cationic polymer comprising a starch, the novel features of said composition being that the starch possesses a combination of (A) a branched, high molecular weight structure as reflected by an amylopectin content of at least 85% and (B) a degree of substitution of about 0.05 to 0.40. Such sizing compositions can be prepared by dissolving the aforementioned starch in water, adjusting the temperature to above the melting point of the sizing agent and adding the sizing agent to the solution so as to form a coarse emulsion , which is subsequently subjected to shear forces to reduce the particle size of the emulsion. The invention also relates to a method of preparing sized paper or paperboard by using the above-mentioned sizing composition. Also, the invention relates to the sized paper for paperboard prepared by said method. Such paper products show reduction in liquid absorbency as compared to products using conventional sizing agents, reduced consumption of optical highteners, and enhanced development of sizing.
