Patent DE-4318932-A1 (DE)
Inventor: FORTMANN NORBERT DIPL ING
IPC: F15B15/22
Filed: 1993-06-03
Abstract: A piston and cylinder device with a reciprocating piston assembly (7) (Fig 1 not shown) co-operates in at least one end position with an end position damper (9) (Fig 1) having a non-metallic stop disc (11) for absorbing the kinetic energy of the piston assembly (7) and a damping seal (15) disposed in an internal space (12) of the stop disc (11) and slidingly sealing on a damping piston (14) of the piston assembly. In order to improve the damping effect with compression damping in addition to the impact damping, a sealed liner (10) is provided which is secured axially in the cylinder barrel (2) and carries the elastic stop disc (11) on a hub projection (22) facing the piston assembly (7), an internal space (10b) being formed in the liner (10) from which the medium compressed by damping can be removed through venting channels (20) which has a throttle adjustable by screw 21. <IMAGE>

Title: Bubble (spirit) level profile
Inventor: HINKEL RALF DR
IPC: G01C15/00
Filed: 1993-07-15
Abstract: This invention relates to a novel cross-sectional profile for bubble levels for improved application and alignment on edges. The object of the invention is to configure the profile of a bubble level such that reliable extension and rendering (transmitting) of edges is made possible in conjunction with a laser. This object is achieved in that grooves (4, 5) and (6, 7), respectively, are applied into the bearing edges of the bubble level (2, 3) in such a way that their surfaces extend axially parallel to the laser axis (1) and the markers (4, 6) produced by the grooves are located at the height of the laser axis (1). In the case of an originally square bubble-level profile with central laser, the marker formed by the groove extends in the middle of the bearing edge. A further V-shaped groove (8, 9) is applied into the profile such that the laser axis (1) is located in the intersection axis of the two groove surfaces (8, 9). As a result of this, during application onto the object edge to be rendered, it is extended directly through the mid-point of the laser. The limb length is in this case selected such that, when applying the profile by the edges (10, 11) onto a planar surface, the distance (d) from the laser axis (1) to the surface is equal to the distance (d1, d2) from the laser axis to the application surfaces (5, 7). The offset to be taken into account therefore always has the same value independently of application variations. <IMAGE>

Title: Process for producing an embossing roller for continuously embossing the surface of a thermoplastic film with a pattern
Inventor: MINKE JUERGEN DIPL ING
IPC: B23K26/08
Filed: 1993-07-24
Abstract: Process for producing an embossing roller for continuously embossing the surface of a thermoplastic film, the embossing face, consisting of silicone rubber, representing a negative form of a pattern to be embossed, in particular of a natural leather grain effect. The grain effect is sensed mechanically or optoelectronically, and the surface information thus obtained is used for the modulation of a laser beam, used to engrave the surface of a roller which represents an endless positive form of the grain effect. A layer of silicone rubber is poured or coated onto this positive form and is vulcanized to create an embossing daughter, which is peeled off the positive form and, with the negative embossing surface outwards, is adhesively fixed onto the circumferential surface of the embossing roller. The difficult replication of the grain effect from the original need no longer be carried out in a number of operations which have to be carried out manually. The process is thus simple and makes it possible for a large number of embossing rollers to be produced cheaply. <IMAGE>

Patent DE-4336673-A1 (DE)
Title: Radial piston pump
Inventor: ROWE GERALD
IPC: F04B9/04
Filed: 1993-10-27
Abstract: The invention relates to a radial piston pump in which an eccentric (12) fixed to a drive shaft (11) drives several pistons (3) arranged in a star shape. Since a pump of this type works with so-called suction governing, the delivery spaces are only partially filled above an average speed range. Consequently, pressure surges which produce noises develop when the piston (3) strikes the oil volume to be expelled. These pressure surges can be reduced if a damping member is fitted between the pistons (3) and the eccentric (12). An annular corrugated spring (16), for example, can be fitted as damping member between an inner and an outer sliding ring (14 and 16 resp.). This corrugated spring (16) allows the piston to deflect slightly at the start of the pressure stroke, so that pressure peaks are reduced. <IMAGE>
Patent DE-4336836-A1 (DE)
Title: Method for obtaining heat and CO2 from a composting plant
Inventor: BRAUN-OPPERT GUENTHER
IPC: C05F17/00
Filed: 1993-10-28
Abstract: The invention relates to a method of obtaining heat and CO2 when organic waste is composted. A heat exchanger is introduced into the reaction space, and this heat exchanger removes only such an amount of heat from the reaction biomass that the reaction temperature does not drop to below 50 DEG C. At the same time, the CO2 formed during the reaction is utilized by being passed into greenhouses connected to the composting plant, or recovered by condensation or chemical reaction and used for other purposes. The reaction biomass is exchanged for fresh material when the reaction temperature has dropped permanently to below 50 DEG C. The spent reaction biomass will still be in particulate form and is therefore well suited for use as a mulch for covering plant beds and the like.

Title: Calender roller cladding monitor useful for early warning of damage
Inventor: KRAPF KLAUS-GEORG DR ING
IPC: G01H1/00
Filed: 1993-11-30
Abstract: The appts. to test a roller, especially the elastic cladding of a calender roller mounted on a pedestal, checks for damage through at least one oscillation detector (3) mounted to the pedestal (4), to register the pulses from probes (2) at the roller on each roller rotation.  An evaluation unit (6) takes the measured values from the oscillation receive (3) as a function of time or frequency, and the probe (2) pulses according to the elapsed time. The components of the measured values are assigned to the separate rollers (1) according to the basic frequencies and the harmonic upper waves from the probes (2) with their rotating frequencies.  The measured values for the rollers (1) give effective values for the oscillation speeds or amplitudes for the separate rollers (1) as a function of the frequency for display and/or to determine a displayed indication of the amount of damage to the roller cladding.

Abstract: A level conversion circuit contains a MOS transistor (Q3) which receives an input signal at its gate, a MOS transistor (Q1) which is turned on in accordance with a reference voltage (Vref) and an output signal, MOS transistors (Q2) and (Q4) which form a current mirror which operates with the current from the transistor (Q1) used as current mirror source, and a capacitance element (Cs) which transmits the input signal to the gates of the current mirror transistors (Q2) and (Q4) by means of capacitive coupling. A transistor (Q3) charges an output node (NB) to the level of a power supply potential (Vcc) and a transistor (Q4) discharges the output node (NB) to the level of a second power supply potential (Vee). When the input signal is at a high level, the gate potentials of the transistors (Q2) and (Q4) rapidly increase due to the capacitive coupling. By reducing the value of the current delivered through the transistors (Q1) and (Q2), a level conversion circuit can be obtained which operates at high speed with little current consumption. When the level conversion circuit is used in a semiconductor storage device, a semiconductor storage device can be obtained which operates at high speed with little current consumption. The semiconductor storage device also contains various structures such as, for example, a bit line load circuit, a ... Original abstract incomplete. <IMAGE>

Title: Method for the automatic testing and maintenance of the metering accuracy of multicomponent metering installations
Inventor: TEUCHERT VOLKER DIPL ING
IPC: G05D11/13
Filed: 1994-09-24
Abstract: In the case of multicomponent metering installations, up until now either only the accuracy of individual metering devices has been tested, or additional calibration containers or test volumes were necessary. The method enables the testing of all metering devices and the automatic carrying out of measures to maintain the metering accuracy of all metering devices without the installation of additional containers. In the method, by means of a program in a metering control unit, a product tank - previously emptied - belonging to the installation is filled by the metering devices with a common operating medium, the content of the product tank is measured with high reproducibility and the result of the content measurement is compared with the result of supervisory measurements of the metering devices. The difference between the two values is the metering error. From the metering errors of individual metering devices, compensation values are automatically calculated with which the metering devices are slightly corrected. The method is suitable for the testing of the metering accuracy and maintenance of a high accuracy in the case of discontinuously and continuously operating multicomponent metering installations.
