Title: Torque control for IC engine
Inventor: ZHANG HONG DR
IPC: F02P5/15
Filed: 1995-05-23
Granted: 1996-12-19
Abstract: To control the torque of an IC engine, a setpoint is created for the torque thus increasing it to reduce the engine braking effect when at least one wheel is tending to skid. This setpoint is converted into a setpoint for the air admission quantity to the engine, the air admission being via an electrically operated throttle flap (14). The air admission setpoint is dependent on the leakage air flowing through the engine and/or is corrected depending on the air flow through the fuel tank ventilation valve. The conversion of torque setpoint to air admission setpoint takes into account the ignition timing and the engine speed.

Title: Machine portioning filling into individual packs formed from flexible tube
Inventor: HANTEN JUERGEN
IPC: A22C11/10
Filed: 1996-02-23
Granted: 1997-04-17
Abstract: In a sealing machine for producing portion packs like sausages or the like, the individual portions are made by crimping the flexible tubular container (4) surrounding the filling (7) using a crimping element, where at least one seal is placed on the pinched area (20) formed between the portions. The crimping element has at least four strips (11) which are pivoted on a circle concentric with the tube axis (5) while their free ends are guided on a rotary ring (12) also concentric with the tube axis (5) in such a way that they extend like chords in the partial circle of their pivots (10) and can perform both pivoting and longitudinal movements in their main plane in relation to the ring (12). When the ring (12) rotates, the strips (11) pivot and move in such a way that the aperture (19) formed between them is reduced from a maximum allowing the filled tube (4) to pass through, to a minimum crimping said tube (4) to form a pinched area (20). It is of advantage to provide two such crimping elements which can be spread axially apart when closed, where the end regions of the rings (12) bearing the strips (11) are joined together by guide rods (23, 24) parallel to one another and to the tube axis (5).
Patent DE-19610732-C1 (DE)
Title: Control of hydraulic pumps with cyclical demand esp. on injection moulding machines
Inventor: PALLMER HANS PETER
IPC: B29C45/76
Filed: 1996-03-19
Granted: 1997-05-07
Abstract: The energy consumption of hydraulic machinery, esp. plastic injection moulding machines, with cyclically varying demands is reduced by providing characteristic signals from at least one sensor in the machine installation.  One or more hydraulic pumps are driven by frequency controlled motors supplied by a frequency changer.  The signals are processed by a logic interface to control the frequency changer.  During the first cycle after start-up at maximum speed, closely spaced measurements of actual demand on the hydraulic pumps are stored.  At the same time the logic circuits of the interface calculate the differences between the measured demand and the maximum demand, within a pre-determined range of maximum and minimum demand, and these are also stored. During subsequent cycles the motor speeds are reduced during periods when the demand is known to be of lower value for predetermined minimum periods of time.  In further cycles the interface uses the actual measurements of demand to correct the stored values.  If the required correction exceeds a predetermined amount the motor speed is raised to the maximum and a new operating sequence is stored.

Inventor: WEIS MANFRED
IPC: H02J3/14
Filed: 1996-04-22
Granted: 1997-10-16
Abstract: A method for optimising and managing the demand for electrical energy in industrial enterprises, in which for one production cycle, on one side, the total reference output or rating is measured as energy (power) per unit time and, on the other side, as consumer-specific reference outputs, and from the results obtained, the switch-on/switch-off of individual consumers is determined during the course of the production run or cycle. The respective energy or power per unit time is analyzed locally and on the basis of these local calculations suitable consumers are selected at the central station and can be switched on or off depending on a given process-and-engineering interrelation with the production cycle.

Title: Inductive separation of metal end caps from glass fluorescent tube for reprocessing
Inventor: MELBER ALBRECHT DR
IPC: H01J9/50
Filed: 1997-08-11
Granted: 1999-01-28
Abstract: The method involves bringing the end cap (4a) to be removed into the operating range of an induction coil which is positioned concentrically to the cap. A current is passed through the coil to generate an magnetic field which warms the cap so that it expands and releases the connection between the cap and the glass body (6) of the fluorescent tube. A gripping device separates the cap from the glass body, while keeping each of them in one piece. During the heating, the solder connection between contacts on the end cap and the wires to the lamp tube melts.

Title: Mineral oil temperature-dependent viscosity and viscosity index are determined from damping of excited magnetostrictive rod at differing temperatures to assure e.g. marine engine oil is fit for purpose
Inventor: WUNN THORSTEN
IPC: G01N33/30
Filed: 1999-01-26
Granted: 2000-07-06
Abstract: A magnetostrictive sensor rod (13) immersed in the liquid, is pulsed into longitudinal oscillation, the viscosity being inferred from damping of the oscillations. Temperature is controlled to a low value. The liquid, in a closed container, is stirred, promoting flow along the rod. The viscosity is then measured. Lastly, stirring is re-commenced and the temperature is raised to a new, higher level. The new viscosity is measured. Viscosity measurement follows an interval of calm, without stirring.  An Independent claim is included for the corresponding viscometer. Key features include excitation of the rod by a coil (11) fed with electrical pulses, a temperature sensor (12) and the cylindrical vessel (2) employed for heating and mixing. Preferred features: The viscosity index is determined from two viscosity values taken at upper and lower reference temperatures. Measurements are taken repeatedly to calculate the average. Flow along the rod (13) is promoted by the spiral stirrer (16) parallel to it.

Title: Ultrasonic transducer for measurements in gases, employs cast elastomer between its sidewalls and an outer holder, to prevent undesirable wall coupling
Inventor: HEINZ MARTIN
IPC: G10K11/00
Filed: 1999-06-18
Granted: 2000-12-07
Abstract: An ultrasonic transducer.  The connection between transducer casing (3), the sidewalls and the holder (8) is formed by a cast elastomer, engaging one or more projections or recesses (9, 10) in their walls, and completely covering the rear of the casing.  An Independent claim is included for the method of making the transducer. A special mold fits between and locates the casing and holder, relative to each other.  This mold part-fills an interspace that is defined between them, up to a point to which the elastomer should reach. The remaining interspace is cast with elastomer. The mold is then removed, and the plastic foam is used to fill the interspace. Alternatively, a prefabricated foam of this type is adhered into place.  Preferred features: Elastomer hardness is less than 50, on the Shore A scale. The shapes of the recesses and projections depart from rectangular when seen in cross section. This facilitates the escape of bubbles during casting. The edges are angled. The edges of the recesses and projections facing the base are angled with respect to it, to allow the bubbles to escape. Sidewalls have a circumferential collar as a projection; the holder has an internal circumferential groove as a recess. On the transducer body (1) a rear damping layer (5) is provided, on top of which the elastomer rests.
