Patent DE-19717684-A1 (DE)
Title: Double-acting fluid-actuated brake device for hydraulic and pneumatic lifts
Inventor: HAHN GUENTHER
IPC: B66F3/30
Filed: 1997-04-28
Abstract: The brake device has two fluid-filled chambers and piston rods (9) operated from outside.  The chambers are connected by a first overflow channel (36) which can be closed selectively by a valve unit.  The valve is operated by an actuator which works depending on the amount and direction of fluid flowing out from one fluid-filled chamber into the other.  A second overflow channel (37) connects the two chambers together and contains a flow valve .
Patent DE-19718449-A1 (DE)
Title: Building insulation panel end rail
IPC: E04B1/76
Filed: 1997-04-30
Abstract: The engagement edge (6a) of the second part of the rail (6) forms a receiver pocket for the engagement edge (4b) of the first rail part (4). The two rails can thus be engaged by a simple swivel movement round the axis defined by the rail. A step (18) at the transition to its engagement edge on the first part is gripped from behind by an angled part (16) of the second rail part. The pocket presents a wedge in section to take the two rail part ends. Fixed to a plastics strip (8) at the rail (2) end furthest from the building (12) is a net-type reinforcing material (24) for the plaster (28) on the insulation concerned (14). The strip terminates in a drip nose (30).
Patent DE-19721046-A1 (DE)
Title: Method of determining refractive indices of transparent and absorbent films
Inventor: RICHTER UWE DIPL PHYS
IPC: G01J4/00
Filed: 1997-05-09
Abstract: The method involves using a PCSA spectroelliptical arrangement, whereby the film thickness is determined by measuring the axial position and phase shift. The degree of polarisation is also determined, whereby the Fourier coefficients in the beam are measured with and without a compensator and are used in a mathematical relationship to yield the degree of polarisation: Pgr {(s2<c>)<2>(1 - C2 theta A)<2> + (s2<p>)<2>(1 - C2 theta C2P)<2>/S2 theta 2S2P<2>C DELTA <2> + S ETA +D<2>(D<2> + L<2>)}<\>2. The corrected measurement value, s2, for the Fourier coefficients is determined from the uncorrected value, s2*, and the degree of polarisation using another mathematical relationship: s2 = s2*/Pgr. The corrected value is used to derive the corrected axial length and phase shift. The mathematical relationships: s1<c> = {A - C2 theta }/{1 - C2 theta A} and s2<c> = {s2 theta s ETA +D(D<2> + L<2>)\2}/{1 - C2 theta A} are used to calculate the values cos 2 theta , cos DELTA  and sin DELTA , where ( ETA  \=) for the values s1<p>, s2<p>, s1<c> and s2<c>, and used to calculate the values of the axial position,  theta <p>, theta <c>, and the values of the phase shift,  DELTA <p>,  DELTA <c>, and thence the film thickness. A,D and L are instrument contents, Cx is an abbreviation for cos(x) and Sx is an abbreviation for sin(x).

Patent DE-19830600-A1 (DE)
Inventor: BINDER ERWIN
IPC: D21F1/66
Filed: 1998-07-09
Abstract: The system for the mixing and recirculation of fiber pulp with returned extracted water from the fourdrinier section, at a machine for the production of paper or cardboard with a stock inlet using controlled dilution water, has a unit (17) to increase the pressure in the path between the mixing vessel (7) and the vessel (1) to hold extracted water from the fourdriniers. The mixing vessel (7) has one chamber (7.1) with a number of feeds (4-6), and a second chamber (7.2) with at least one take-off (15) to the extracted water vessel (1). An overflow (19) gives a flow connection between the two mixing vessel chambers (7.1,7.2). An impeller pump (17), between the mixing (7) and extracted water (1) vessels gives the increased pressure. A control valve (18) is in the connection between the two vessels (7,1). A control circuit (16.1,16.2) determines the fluid level in the mixing vessel (7). Two concentric feed pipes (19,20) give a feed of fresh matter and the return flow at the extracted water vessel (1). An additional concentric pipe (21) at the feed and backflow pipes (19,20) takes the inflow into the extracted water vessel (1) from the cleaning station overflow. A gap is between the pipes (19-21) in the flow direction, and their ends are positioned from the outwards towards the inwards, in sequence. The feed tube (21) for the backflow ends before the end of the feed pipe (19), A mixer, such as a propeller, is in the mixing vessel (7). An Independent claim is included for the operation of the system, where the extracted water is taken from the wet section of the machine to be passed to a container (1). The mixing vessel (7) takes the backflow from the recirculating pulp at the stock inlet, the usable suspension from at least one vertical sorting stage and the backflow from a pulp cleaning stage, to be mixed together. The backflow (4-6) is injected into the lower section of the extracted water vessel (1) through a pressure increase unit (17) such as a pump, to be mixed with the extracted water and fresh material (8). The mixture is delivered to the stock inlet through a cleaning stage and/or a vertical sorter. Preferred Features: The backflow (4-6) is fed into the first mixing chamber (7.1), to pass to the second chamber (7.2) through an overflow, and is passed to the extracted water vessel (1) by a pump (17). The backflow (4-6) is controlled by a level monitor at the mixing vessel (7). The backflow (4-6) and the fresh material (8) pass into the extracted water vessel (1) through two concentric pipes (19,20), and the overflow (22) from the cleaning stage is passed into the lower section of the extracted water vessel (1), using an assembly of three concentric pipes (19-21).

A printing plate (8) is directly fastened, e.g. adhered onto each cylinder (6) at existing location marks (7). An additional sensor (18) detects location marks intentionally applied to the advancing band of material, and interfering marks caused by adhesion of separate band sections together for continuity. In accordance with these signals, angular phase and/or rotational speed alterations are calculated.

Title: Downward choke converter for motor vehicle, has controllable switch behind input in series with choke in longitudinal branch, with capacitor in cross branch at output and second controllable switch
Inventor: DITTMER BERND
IPC: H02M3/158

Abstract: The downward choke converter is designed with two controllable switches (T1,T2) consisting of two MOSFET transistors for forming a synchronous rectifier. A control unit (20), especially a pulse width controller is provided for the MOSFET transistors (T1,T2).  The voltage over the MOSFET transistor (T2) in the cross branch is monitored, for whether a rearward current flows through the choke (L) in a direction from the output (25) to the input (10) of the choke converter, or whether the voltage potential (1) at the center tapping of the half wave bridge, formed by the two MOSFET transistors (T1,T2) is detected. With the occurrence of such a backward current, or critical voltage potential, the MOSFET transistor (T2) in the cross branch is blocked, in order to prevent the rearward current.
