Patent DE-4412352-A1 (DE)
Title: Tunnel dryer for ceramic mouldings has improved air movement for drying low brick or tile stacks
Inventor: HONCAMP STEFAN DR DR ING
IPC: C04B33/30
Filed: 1994-04-11
Abstract: In the drying of ceramic mouldings, e.g. bricks or pantiles, the mouldings (4) are stacked at low height (max. 80 cm.) and in transverse rows on transport bases (3) such that transverse air blowing gaps (7) are left between adjacent moulding rows. The transport bases (3) move through a counter-current aerated drying tunnel (2) in which an undulating locally accelerated longitudinal flow is created by stationary baffles (9, 13). Air exchange is effected in the tunnel (2) by opt. longitudinal circulation circuits in addn. to the longitudinal flow (L), each circuit comprising: (a) blasting of drying air against the charge and/or into the blowing gaps (7) from the air gap (10) of a transverse nozzle box (9) which also acts as baffle for the longitudinal flow (L); and (b) subsequent rising of the air into the longitudinal flow (L).  Also claimed is a tunnel dryer for drying ceramic mouldings.

Title: Hydraulic control device for gear-change elements of a power-shift transmission
Inventor: PRUES LUDWIG DIPL ING
IPC: F16H61/00
Filed: 1994-04-20
Abstract: The invention relates to a hydraulic control device for gear-change elements (K1, K2, K3, B1, B2) of a power-shift transmission, the said elements being guided in a valve casing (1). The significant components of this control device are a main pressure valve (4), a manual spool valve (5), a pressure-relief valve (2) and various spool and solenoid valves (S1/E1 to S4/E4). To ensure a compact construction, the proposal is that the pressure relief valve (2) and a main-pressure modulator valve (E5) should be arranged in series in parallel with the spool valves (S1 to S4) (Figure 1). <IMAGE>

Title: Fault-current circuit breaker
Inventor: MOESSNER GEHARD DIPL ING
IPC: H01H71/12
Filed: 1994-12-07
Abstract: The device has a transformer (14) whose primary winding is formed by the mains lead. The transformer secondary winding (15) is connected to a trigger (16). The latter actuates a release lever (20) to release a latching point in a switch latch, when a secondary signal generated by a leakage current in the mains lead appears. When the lever (20) is actuated, switch contacts in the mains lead are opened. The trigger (16) is a piezoelement which is actuated by the secondary signal and is deflected by it and acts directly on the latching point. The piezoelement (16) has two strip-type parts connected to each other by a conductive layer acting as a pole. The free parallel surfaces of the strips are coated with a metal layer acting as an electrode forming the other pole. The piezoelement is in the shape of a spiral. Its inner end (18) is fixed. Its free outer end (19) is deflected on appearance of a leakage current and acts on the latching point.

Patent DE-4446795-A1 (DE)
Title: Filter device for separating bone pieces
Inventor: TROJAN MARTIN
IPC: B01D45/12
Filed: 1994-12-24
Abstract: The filter device consists of an upper filter part (1) and a lower filter part (4) with an intermediate O-ring (6), filter sheet (2) and filter support (3). The upper and lower parts are screwed together. A bridging channel (7) allows free passage between the upper and lower parts and is at a suitable distance from an inlet channel (5) and the filter sheet. The substance that is sucked up thus passes first to the filter sheet and not to the bridging channel. The bridging channel is designed so that the pressure difference between the filter inlet and outlet is reduced so that the bone fragments do not form in a compacted manner on the filter allowing for easy rinsing with glycerine etc. The suction unit is attached to a connector (8) on the lower filter part (4).

Title: Process for monitoring a driven movable door or similar
Inventor: HOERMANN MICHAEL
IPC: E05F15/668
Filed: 1983-01-11
Abstract: To monitor the movement of a driven door on its movement path and to control this movement in a very sensitive manner by disconnecting or reversing the drive when obstacles are present, the true characteristics of the movement of the door as a function of its movement path are constantly detected for each successive cyclic movement of the door which is detected. The signals thus obtained are compared with a function which is continually interrogated for each movement monitored. This function is recorded and memorized depending on the door movement to be monitored before it operates in order to ensure normal and obstacle-free operation.

Title: Multi-way valve for changing the flow direction of gaseous or liquid media
Inventor: MERTEN FRITZ
IPC: F28G1/12
Filed: 1985-08-21
Abstract: Owing to the level of pollution of the liquid coolant flowing through the tubes of heat-exchangers of air-conditioning units and condensers it is essential to clean the tubes at regular intervals by means of mechanical cleaners, such as brushes. The valve required for the purpose of reversing the normal flow must be of small dimensions, robust and of simple design. For this a valve (1) is proposed in which two pipe ends (3-4) (5-6) are each arranged in their respective planes, and in which the plug (9) is supported movably. The plug has, for this purpose two flow passages (15-16) in the normal direction which connect the pipe ends by the shortest route. For the reverse direction, the plug is fitted with two spirally-shaped passages (17-18) which independently connect, in a cross-over manner, the pipe ends.

On met l'ADN en contact avec de l'ADN oncogène marqué ou avec des sondes à oligonucléotides, afin d'hybrider ceux-ci avec l'ADN lorsque des séquences complémentaires sont présentes. On elimine l'excédent d'ADN oncogène marqué ou de sondes à nucléotides n'ayant pas formé des liens spécifiques et on analyse le produit pour déterminer la présence d'ADN ou d'oligonucléotides marqués. On peut procéder à une amplification enzymatique in vitro avec l'ADN du plasma, après l'avoir concentré ou séparé, afin d'obtenir la multiplication des séquences-cibles spécifiques de l'oncogène. Ce procédé convient comme test universel de dépistage de malignité.

Abstract: Es gibt verschiedene Herstellverfahren solcher Schaltsilber-Kontaktauflagen, die jedoch entweder in der Handhabung der Schaltsilber-Kontaktauflage, der Silberzwischenschicht, des Kontaktplättchens und des Kontaktträgers sowie des Lötens derselben recht aufwendig sind, oder die von Streifenmaterial entsprechender Zusammensetzung ausgehen, diese Streifen aufeinander aufwalzen und an den Rändern beschneiden. Bei dem letztgenannten Verfahren entsteht jedoch Edelmetall-Abfall. Um diese Nachteile zu vermeiden, sieht die Erfindung vor, daß das Lot in Form eines Plättchens (6) vor dem eigentlichen Vorgang auf der Silberzwischenschicht (4) angeheftet wird. Dabei ist es besonders vorteilhaft, wenn diese Anheftung durch Ultraschallschweißen erfolgt. Die Erfindung ist bei allen Schaltsilber-Kontaktstücken anwendbar.
