Patent DE-19619748-A1 (DE)
Title: Filling bulk material container, especially for vehicle with specified filling volume
Inventor: MINOR HORST DIPL ING
IPC: B65G47/19
Filed: 1996-05-15
Abstract: The method uses a filling system which includes a weighing bunker (1) under the control of the filling wt. The filling height is measured at two points (44, 45). The facility for preventing an overfilling of the bulk material container (5) is designed so that the vol. of the bulk material in the weighing bunker is determined also, and that either the filling is stopped as soon as the max. filing vol. of the container (5) is reached. Alternatively using the load cells (14), the weight and determined vol. of the bulk material computes the filling wt. corresp. to the specified max. filing vol. and only one amount corresp. to the computed filling wt. is delivered to the weighing bunker, as long as this does not exceed the max. filling wt. of the filling material container (5).

Patent DE-19627731-A1 (DE)
Inventor: WEINHARDT MICHAEL DR ING
IPC: B60T8/00
Filed: 1996-07-10
Abstract: A system for measuring and setting suitable parameters for the control of a rail vehicle's driving and braking modes has a wheel loading limiter (1) with a controller. At least one measured variable for the wheel loading is passed to the input of the limiter as well as at least one threshold value for the permitted loading. The controller limits the loading to the threshold and forms another parameter to influence the drive and brake control system (2). At least one measured variable for the wheel loading is found by a sensor and at least one is estimated by an observer. As a measured variable, one can choose the wheel surface temperature, the traction force, the braking force, the slip speed, etc.

Title: Frame especially for a platform or a scaffold or for decking formwork used in construction
Inventor: HOLLMANN NIELS DIPL ING
IPC: E04G11/48
Filed: 1996-09-05
Abstract: The frame has upright supports (2) and cross beams (10), which are attached with their ends to the supports. A positively formed fixture is provided between the supports and the beams by an elevatable part of the support-beam connection, which provides against movement in all three spatial planes. The supports are free from lateral protrusions beyond their outer boundary at the point of connection. The fixture is formed by the engagement of a protruding element (68) from the beam into openings (18) in the support. The protruding element can be shifted to and fro in a direction corresponding to the longitudinal direction of the beam.
Patent DE-19639134-A1 (DE)
Inventor: MUELLER JOACHIM
IPC: B41F33/00
Filed: 1996-09-24
Abstract: The sheets (1) to be printed are delivered from a stack to the press by a feed mechanism which can be cut in and out. The mechanism is cut in with the press running at a low basic speed, after which it is accelerated. The point in time to start the run-up to the intended production speed is determined dependent on the number of press revolutions necessary to deliver the first sheet from the stack to inside the press. Typically the predetermined point is the first printing zone. The system ensures that, after cutting the sheet-feed in, the first sheet does not reach the predetermined position inside the press until or after production speed has been reached.

Patent DE-19652698-A1 (DE)
Title: Precision measurement system for AC and other electrical dimensions fluctuating over time
Inventor: GERMER HORST PROF DR ING
IPC: G01R19/25
Filed: 1996-12-18
Abstract: The system uses a representative set of sample values. These are derived from continual comparison of the measured signals (M) with test values (T) obtained in statistically valid distribution by use of a random generator (7) and A-D converter (8). From the compared results (A,B,C) and the random figures (2) all measurement values can be calculated in a computer (6), using fixed algorithms. The method ensures that no individual sample values have any appreciable effect on the results. The mean value or maximal and minimal values can be obtained with great accuracy in a short period of time.

Title: Flushing equipment for extracorporeal blood-treatment circuit
Inventor: POLASCHEGG HANS-DIETRICH DR
IPC: A61M1/34
Filed: 1997-02-07
Abstract: The circuit has an arterial hose system leading from the patient to the blood-treatment unit and containing a blood-pump. A venous hose system leads back to the patient from the unit and contains a drop chamber or pipe junction. A flushing-solution bag is connected by a first pipe with low flow-resistance to the arterial hose system upstream of the pump, and the pipe can be shut off by a clamp or valve. A second pipe with high flow resistance connects the bag to a substitute source, and can be of the capillary type (364). Alternatively, it can comprise a section of low flow-resistance in series with one of high resistance, the latter typically consisting of a sterile filter. Flow resistance can be adjustable by a clamp, and the bag can be enclosed between two plates, the distance between which is adjustable.
Patent DE-19704679-A1 (DE)
Title: Adhesive packaging tape dispenser for simultaneously sealing top and bottom sides of package
Inventor: YEH TSUANG HANG
IPC: B65B51/06
Filed: 1997-02-07
Abstract: The dispenser has two positioning plates (2) forming the dispenser side walls. Arms (22,23) for supporting the front and rear tape press wheels (24,25) are secured between the two plates and joined to each other by a connector piece that enables the two wheel supports to move relative to each other. The arms are pressed against a strong spring. A tape cutter blade (261) is held between bracket arms (26). The actual roll (4) of tape is held between the plates on a holder (42). Two tape holder plates (31) are secured to the front press wheel support arms underneath the wheel, extending inwards from the support arms and at an angle towards the front of the front wheel support arms. A first guide roll (27) guides the tape upwards, whilst a second guide roll (29) with a chequered surface relief is located beneath the holder plates at the front press wheel support arms. The tape leaves the roll and is non-sticky surface is guided upwards over the first guide roll, then its sticky surface is guided over the second guide roll and upwards through the space between the holder plates, and then the tape runs at a tangent to the front press wheel. A fourth guide roll (32) is positioned between the holder plates and the second guide roll. The end (321) of the fourth guide roll shaft can move inside a hole (221) locates in one of the front press wheel support arms. When the end of the shaft lies in the top of the hole, the section of tape runs at a tangent to the holder plates between the front edge of the outside of the fourth guide roll and the fourth (sic) press roll, so that the tape is not in contact with the holder plates. When the dispenser is not being used the end of the shaft rests in the bottom of the hole, so that the weight of the fourth guide roll is pressed against the tape, forcing the tape to stand upwards and not drop off the dispenser.

Patent DE-19721810-A1 (DE)
Title: Monitoring method for dirt accumulation in heat exchangers
Inventor: DREIBACH JOACHIM
IPC: F28F19/00
Filed: 1997-05-26
Abstract: The monitoring method involves monitoring the surface temperature of a heat exchanger, or that of an adjacent area, using infrared rays. The resulting values are compared with a reference value range by a central computer which indicates any deviation outside the reference range. Infrared or optical monitors attached to the heat exchanger transmit signals to a central computer which stores information concerning a reference value range for normal outputs and data concerning the outside and ambient temperatures. Abnormal operation of the heat exchanger is recognised and the requirement for service is indicated.  Routine cleaning of heat exchangers to reduce efficiency loss due to the build up of dust particles may be unnecessary in some cases but the need for cleaning is detected only when it becomes necessary.
