Title: Vacuum drum filter has external scraper and internal nozzle - for back blowing combined with second following nozzle for cleaning agent
Inventor: MICHALSKI LOTHAR
IPC: B01D33/06
Filed: 1980-12-24
Abstract: A vacuum drum filter has a filter cake removal device outside the drum, together with a blowing device opposite this removal device inside the drum; the blowing device consists of a blowing shoe bearing against the inside of the drum, mounted on the fixed hollow shaft of the drum filter and capable of moving along the inner wall of the drum. A further blowing zone, intended particularly for cleaning agent, comprises a blowing device disposed behind the filter removal device in the rotational direction. These two blowing devices are combined into one single blowing shoe which covers the two blowing zones. Each blowing device has its separate duct; the face of the shoe, which covers the inner face of the drum wall in this zone at a slight distance from it and acts as a sealing surface, is covered with a liner. Pref., this liner is replaceable and comprises an elastic plastics plate of wear-resistant material, such as PTFE or "TEFLON" (RTM), and is 5-20 (10) mm thick. Used as an air or gas filter. The wear normally associated with the blowing devices on the inner face of the drum is considerably reduced and only the PTFE facing sheet normally needs to be replaced.

Title: Flexible rod coupling, in particular for gear-change linkages in motor vehicles
Inventor: WAEHLING WERNER
IPC: F16F1/54
Filed: 1981-01-20
Abstract: The rod coupling (18) has two coupling parts (20, 30), each with two elastomer bodies (26 and 36 respectively) which are situated opposite one another in pairs and each have a rolling contact surface (28 and 38 respectively). Viewed in a section containing the axis (A) of the rods, the rolling contact surfaces (28, 38) are of concave configuration and arranged between them are rigid rolling elements (40), each of which can be made to roll about a rolling axis (W) extending transversely to the axis (A) of the rods. This makes possible relative motion of the two coupling parts counter to gradually increasing restoring forces, namely rectilinear relative motion along the axis (A) of the rods and flexure about a central axis (Z) normal to the axis (A) of the rods. The rod coupling (18) permits sensitive transmission of motion between the gear lever (16) and the gearbox (14) of a motor vehicle but the gear lever (16) remains largely decoupled from vibrations of the gearbox (12). This is especially advantageous in front wheel drive motor vehicles with a transverse engine (10). <IMAGE>

Title: Structured chemically reducing metal deposit
Inventor: GIERTH LOTHAR DR RER NAT
IPC: H05K3/18
Filed: 1981-10-02
Abstract: The process involves the deposition of additively laser-structured metal layers from chemically reducing baths on electrically nonconducting or semiconducting surfaces. The novel process does not employ a mask and makes it possible to apply, in particular, even very narrow metal tracks. In addition, the process operates with extremely high economy of material. It is characterised in that all the known metallisation baths are used at room temperature and the required working temperature is produced with the aid of a suitable laser only at the point on the substrate which is to be coated. Metal tracks are produced by moving laser and substrate relative to one another. After suitably pretreating the substrates (cleaning, degreasing, etching) they are activated in the usual way and placed in a chemically reducing metallisation bath with the side to be coated upwards. The desired structure is then irradiated or heated with the laser, and the substrate is removed from the bath, rinsed and dried. Application in electronics and allied fields.

Patent DE-3225352-A1 (DE)
Title: Photographic camera having a film feed and shutter cocking device
Inventor: SITZLER KLAUS
IPC: G03B1/62
Filed: 1982-07-07
Abstract: A cocking lever (11), which is mounted eccentrically relative to the axis of rotation of a cocking member (4) and on a shutter drive member (8) is actuated by a tension spring (12). The longitudinal extent of a web (11a) of the cocking lever (11), the tension spring (12) and the bearing (8d) of the cocking lever (11) are arranged approximately on one line which extends transverse to the path of motion of a cocking member projection (4a). The web (11a) is situated in the path of motion of the cocking member projection (4a) and is carried along in the direction ''B'' of the arrow during rotation of the cocking member (4). The cocking lever (11) moves the shutter drive member (8) via a projection (8b) into a cocked position. Owing to eccentric mounting of the cocking lever (11), the relative position of the projection (4a) with regard to the web (11a) changes in such a way that the latter disengage when the cocked position is reached. The cocking lever (11) and the web (11a) thereafter resume their original alignment, but because of the eccentric mounting are held in a withdrawn position in which the web (11a) is situated outside the path of motion of the projection (4a). As a result, the cocking member (4) can be moved further in order to control the film feed without influencing the shutter drive member (8). <IMAGE>

Patent DE-3230314-A1 (DE)
Title: Toggle drive
Inventor: ROMES ROMAN
IPC: B30B15/28
Filed: 1982-08-14
Abstract: The toggle drive of presses or mould parts of plastics injection moulding machines according to Figure 1 has at one of the parts, connected in an articulated manner, of the toggle drive a force-sensing pin (14) connecting said parts. This is designed as a magnetoelastic transducer. A magnetic core (28) having at least one coil (31 to 33) is disposed in a cavity (24) of the pin. With this force-sensing pin the effect is utilised that the permeability of the steel changes when it is under stress by flexion, torsion or shear. The magnetic core (28) is disposed in such a manner that the neutral zone of the flexural stresses, and thus the maximum shear stress, is located in the region of flow - ends of the legs (29, 30, 33). A constant alternating voltage is now applied to the primary coil (33). The measurement voltage is taken off at the outer secondary coils (31, 32). By this means information is obtained about the clamping force, which for example is determined by a control device in such a manner that the clamping force transmitted to the moulds by the toggle drive does not become unnecessarily high. This improves the lifetime of the system or of the mould. …<IMAGE>…

Patent DE-3241261-A1 (DE)
Title: Process and arrangement for measuring humidity
Inventor: NEUSEL ROLF
IPC: G01N21/81
Filed: 1982-11-09
Abstract: The invention relates to a process for measuring relative humidity, abbreviated r.h., which uses the change of the action of suitable materials on light radiation or light-like radiation as a function of the humidity. The transducer materials are therefore to be made spatially very small and of very low layer thickness, and to be mechanically very robust on transparent carriers. A cascading of several transducers in the same beam to increase the sensitivity or to affect the characteristic is no problem. Comparison transducers which are arranged in radiation-transmitting capsules and which are not affected by the rF compensate errors by means of radiation bridge arrangements and compensation circuits. The transducers, light sources and beam detectors are suitable for manufacture by known semiconductor technologies. Since the transducer materials are not contacted, a main cause of technological difficulties, which are unavoidable with known humidity-to-electricity converters, is reliably prevented. The set times can easily be controlled and can be selected so as to be very short, because the mass of the transducer material can be reduced virtually to nill. Radiation sources and radiation detectors here correspond to the state of the art.

Title: Nuclear fuel cluster for a boiling water reactor
Inventor: CROWTHER RUSSELL LEE
IPC: G21C3/328
Filed: 1983-03-12
Abstract: A configuration for a nuclear fuel cluster (15) for a nuclear reactor, which permits the clearance for the cold shutdown state to be maintained in conjunction with minimum impairment of the operating efficiency. The nuclear fuel cluster comprises a component made from fissile material, which is distributed over a substantial axial part of the cluster, as well as a component of neutron-absorbing material having an axial distribution which is characterised by concentration in a relatively short axial zone (65) (the control zone for the cold shutdown state), which corresponds to at least one section of the axial region of the maximum reactivity in the cold shutdown state. The axial distribution of the component made from neutron-absorbing material is characterised by additional concentration in an axial zone (62) (of the hot operating control zone). The component made from neutron-absorbing material is suitably inserted into at least a few of the fuel rods (57-G1, G2, G3, G4). The concentration in the control zone for the cold shutdown state can be at least partially created by one or more fuel rods (G2, G3) which have absorbers only in the control zone for the cold shutdown state. The concentration of the neutron-absorbing material in the control zone for the cold shutdown state can be supplemented by reduced fuel enrichment in the control zone for the cold shutdown state. <IMAGE>
