Inventor: SCHUERMANN JOSEF H
IPC: G07C9/00
Filed: 1989-06-23
Abstract: The interrogation devices are equipped with a receiving section and a transmitting section. Each interrogation device checks as reaction to an interrogation command whether its receiving section (14) is receiving a signal with the carrier frequency. If no such signal is being received, the interrogation device transmits the HF interrogation pulse after expiry of a wait time of at least the predetermined message duration whereas, if it is receiving a signal with the carrier frequency, the HF interrogation pulse is not sent until the reception of said signal terminates and at least the wait time has expired or a delay time has passed which is longer than the sum of the predetermined carrier duration and the wait time.

Title: Glass gob feeder - uses oscillator to draw glass residue back into feed tube
Inventor: KOENIG WILHELM
IPC: C03B7/082
Filed: 1989-11-08
Abstract: In a glass gob feeder, the gob is cut by a sheat from the flowing glass strand emerging from a guide tube. An oscillator makes an abrupt movement in a vertical direction and causes the glass residue to be drawn back into the tube. The oscillating body in the tube acts as the base of the tube during oscillation and, when not oscillating, returns to a position where gob formation can continue. The time between gob formations can be as long as required while the tube can be of different shape according to the type of gob required. ADVANTAGE - Gob supply is not subject to an uncontrolled toning cycle.

Title: Sensor output signal processing circuitry - has signal generator with transmitter, galvanically non-conductive transmit path and receiver
Inventor: ALLERDIST HEINZ
IPC: G08C23/04
Filed: 1990-03-15

Inventor: LANGE RUEDIGER DIPL ING
IPC: D07B7/10
Filed: 1990-10-17
Abstract: The invention relates to a rotating winder for stranding products which has a rotor (1) connected to a drive motor and is borne on a machine frame and in which a winding drum (2) is rotatably fitted which is connected to a drive motor and the axis of rotation (3) of which runs transversely to the rotor axis (4), and which has a traversing fork (14) movable parallel to the winding drum axis (3) as a traversing device for the substances to be wound. The traversing fork (14) moving to and fro transversely to the rotor axis (4) generates changing imbalances which forbid a higher working speed.

Title: Process for operating IC engine using gaseous fuel - comprises evaporating sulphur-free hydrocarbon(s), mixing with water vapour and then converting catalytically to methane-rich gas
Inventor: BARON ELFRIEDE
IPC: C10G11/20
Filed: 1990-12-17
Abstract: During the process sulphur-free liquid hydrocarbons of b.pt. 320 deg.C are evaporated, mixed with water vapour and the mixt. converted catalytically at approx. 350-600 deg.C to a methane-rich gas, the gas is cooled and led to the I.C. engine, where it ignites in the presence of O2 at elevated pressures. The I.C. engine is started up in the known way with liquid fuel and operated for such a time that the catalytic appts. are heated to operating temp. to produce the gaseous fuel, and this starting up operation carried out with a lower air-seal ratio of the I.C. engine than when operating with the methane-contg. gaseous fuel.

Title: Removal of solidified coke produced in crude oil distn. - by milling arrangement which saves energy
Inventor: DARTMANN ROBERT
IPC: C10B33/00
Filed: 1990-12-28
Abstract: A method is claimed for removing a solidified substance from a container e.g. removing from a coking chamber the coke produced from cracked prods. in crude-oil distn..  A vertical hole for the removal is made through the substance, which is then broken up by a milling arrangement and removed through the hole.

Title: Control system for pull-free continuous rolling - with material velocity measured at two points on the span between two rolling units
Inventor: SCHULZE BERND DR ING
IPC: B21B1/18
Filed: 1991-01-23
Abstract: Control system for achieving pull-free rolling in continuous rolling installations incorporating at least two rolling units is based on measurement of the velocity of the material being rolled. The velocities (v1,v2) are measured at the points (MP1,MP2) located respectively after the unit (1) and before the unit (2), and are then compared with one another. The measure of form change of the material between the units (1,2) is determined with the use of the formula phi = 1n (v1/v2) and deviations from the value phi = 0 are used to produce appropriate control signals for equalising the speeds (v1,v2). The velocities (v1,v2) are pref. measured simultaneously. They are measured in succession during the rolling process within fixed time intervals allowing the results to be evaluated. The distance (1o) between the measuring points (MP1, MP2) is specified. USE/ADVANTAGE - The invention can be used in continuous rolling installations with more than one rolling unit. In contrast to currently used indirect methods, it establishes a direct connection between the form change and the relative speeds of the material over the span between two rolling units.
