Title: Paint-drying system
Inventor: BURKAMP MARTIN
IPC: F26B25/00
Filed: 1993-04-21
Abstract: The present invention relates to a paint-drying system with a drier booth (10) and with infrared emitter units (17, 19, 20, 23) which are arranged in groups in this drier booth on supporting structures (16, 18, 21, 22) and which are each arranged at a fixed location in the drier booth (10). According to the invention, the article to be dried, preferably the body (11) of a vehicle, is lifted from below into the drier booth (10) by means of a lifting device (14). The advantage of the paint-drying system according to the invention is that, laterally of and above the body to be dried, there are no movable surfaces, as a result of the movement of which dust is swirled up and therefore the paintwork is damaged. <IMAGE>

Title: Central chain conveyor with two-part scrapers, especially central double chain conveyor
Inventor: THIELE ALFRED DIPL ING
IPC: B65G19/10
Filed: 1993-05-19
Abstract: In the central chain conveyor with two-part scrapers, which is designed especially as a central double chain conveyor, the horizontal links (5), whilst having a specific link strength, for example standardised according to DIN, have a spacing reduced in relation to the standard spacing. The chain-wheel pockets (11, 12) of the chain wheel (1) have a length ("L") corresponding to the length of the shortened horizontal links (5) and smaller in relation to the standard spacing, and the teeth (7) of the chain wheel (1), in the region underneath the chain-wheel pockets (11, 12), have, as a result of the removal of material on the tooth flank (7a) in the running direction (13) and as a result of the addition of material on the opposite tooth flank (7b), a tooth shape which is asymmetric in the direction of rotation of the chain wheel or in the chain running direction. Substantially longer service lives both of the chain wheels and of the parts, cooperating therewith, of the entire chain-conveyor system of such conveyors are achieved thereby. <IMAGE>

Abstract: The joint fitting comprises a joint component which can pivot with the backrest and a joint component which is assigned to the backrest and is fixed in the position of use of the seat. The fixed joint component is connected at its front end facing away from the joint eyelet to the seat component so as to be capable of pivoting by means of a pin for folding forward the backrest while its rear end region interacts with a stop fixed to the seat component. A catch hook which is provided with a hook mouth is pivotably coupled to the joint component coupled to the seat component, a locking device being assigned to the said catch hook, which locking device has an adjustable lever which is rotatably mounted on the fixed joint component and is connected to a locking thumb which is loaded by a spring element in the locking direction and is also mounted on the fixed joint component and secures the catch hook in its locked position. The bearing face, engaging behind the stop, of the hook mouth, has an angle of inclination above self locking. In order to permit on the one hand a compact design and on the other hand to be able to secure the open position of the catch hook during the pivoting movement of the backrest, the adjustment lever is connected to the locking thumb with the inclusion of a small degree of tangential play, it being possible to secure the catch hook to the locking thumb by means of a catch in order to keep the hook mouth of the catch hook open.

Patent DE-4401888-A1 (DE)
Inventor: IGEL MICHAEL DR ING
IPC: H02H3/40
Filed: 1994-01-24
Abstract: The impedance value is proportional to the distance between a fault location and the measurement position at which the currents and voltages of the transmission lines are measured. A summation current compensation matrix is formed using a given summation current equation involving the summation current, the measured conductor currents, the null system impedance and the with system impedance. The summation current compensation matrix is converted into a phase current compensation matrix by replacing a unit matrix with a complex symmetrical correction matrix so that the summation current and conductor current compensation matrices are identical. The impedance in the distance safety arrangement is compared with stored reference values. A power switch connected to the power transmission lines is triggered or not depending on the comparison result.

Title: Pneumatic seed drill for agricultural use
Inventor: STUETTGEN GERHARD
IPC: A01C7/08
Filed: 1994-06-08
Abstract: The pneumatic seed drill has the seed transported to the drilling head through a duct (2) using a standard input air pressure.

Patent DE-4428097-A1 (DE)
Inventor: SCHWARZ HANS-JOCHEN DR ING DR
IPC: F23M9/06
Filed: 1994-08-09
Abstract: The invention concerns a method of operating a heater as well as a heater operated by the method, the heater having, located in a combustion chamber (12), a burner head (20) designed to disperse a fuel-air mixture plus a fan (16) to convey the preferably premixed fuel-air mixture into the combustion chamber.

Title: Suction supply control for textile machine
Inventor: HORAK DIETER
IPC: B65H69/06
Filed: 1994-12-23
Abstract: The control of under-pressure in the suction system of a textile machine with a number of workstations, each with different suction requirements, sets the rotary speed of the suction system drive motor to cover the basic need of the whole machine. When an indication is received at the control, that an increased underpressure supply is required, the motor speed is increased before the raised underpressure demand to raise the underpressure to give a stronger suction action to cover requirements without falling below the basic supply level.
Patent WO-8103680-A1 (WO)
Inventor: BAELZ H
IPC: F24D10/00
Filed: 1981-06-19
Abstract: According to the method for the controlled transmission of heat from a primary steam circuit (010), the supply (04) of the consumer (2) is effected at a certain pressure whereas the return (02) is at a lower pressure. In order to allow the steam pressure of the steam circuit to be used and thus to obtain the driving power for the supply (04) of the consumer during the heat transmission from the primary steam circuit (010) to the heat consumer, the steam taken from the steam circuit (010) is cooled to condensation according to the heat consumption of the consumer (2), by drawing off heat by means of a secondary medium and by maintaining a certain overpressure with respect to the supply pressure of the consumer. Then, the overpressure is reduced in a jet pump (8) to the supply pressure by producing the driving power for the supply (04), and the secondary medium heated by the cooling of the steam is mixed with the supply.

Abstract: Dans un procédé pour surveiller un réseau informatique avec au moins deux abonnés reliés via un bus de données comprenant au moins deux lignes, chaque abonné possédant une partie d'émission et/ou de réception, la fonction du bus de données et/ou la fonction des abonnés contrôle au moins un abonné à l'aide de signaux de détection d'erreurs (signaux de surveillance, CEI), et des mesures de fonctionnement d'urgence (M1; M2) adaptées à l'erreur en question sont adoptées afin d'établir des modes de fonctionnement d'urgence définis (fonctionnement exceptionnel monoconducteur, fonctionnement spécial en urgence). Après adoption de la première mesure d'urgence (M1), on teste le réseau informatique pour y déceler d'éventuelles erreurs. Si aucune erreur n'est détectée, la première mesure d'urgence est maintenue et par conséquent le mode de fonctionnement en urgence qui en résulte (fonctionnement exceptionnel monoconducteur). Si d'autres erreurs apparaissent dans le réseau informatique après adoption de la première mesure d'urgence, cette dernière est annulée et la deuxième mesure d'urgence (M2) est adoptée. Si aucune autre erreur n'apparaît, le fonctionnement en urgence instauré par cette mesure, à savoir le fonctionnement spécial d'urgence, est maintenu. Ce n'est que si d'autres erreurs apparaissent encore que les abonnés concernés ou le réseau informatique tout entier sont déconnectés (bus hors circuit).
