Patent DE-3316557-C1 (DE)
Title: Ceiling formwork system
IPC: E04G11/48
Filed: 1983-05-06
Granted: 1984-10-11
Abstract: In a ceiling formwork system, having longitudinal girders (2), carrying formwork panels (1), and drop heads (3) between supports (4), it is proposed, in order to introduce the carrying forces as far as possible without tilting moment on the support (4), to guide the drop piece (8), at least in the upper operating position, only in its lower region with a small amount of play on the shaft (6) of the drop head (3) and to extend the guide stepwise or conically upwards, so that the drop piece (8) can perform a certain tilting movement relative to the shaft (6), so that no bending moments can be transmitted in this tilting region and hence the buckling stress of the support (4) is kept as low as possible for an appropriate constructional outlay. <IMAGE>
Patent DE-3326035-C1 (DE)
Title: Electro-hydraulic control system for support assemblies in underground mine working
Inventor: BERGER KARL-HEINZ DIPL-ING
IPC: E21D23/12
Filed: 1983-07-20
Granted: 1985-01-31
Abstract: It is known directly to control hydraulic consumers of support assemblies via solenoid valves. On account of the safety regulations in mining, however, these solenoid valves, requiring a high electrical output, have to be encapsulated in such a way that the space required for this is in many cases not available. Indirect control has therefore been adopted in which smaller electrical outputs combined with an intrinsically safe construction are possible. In order also to ensure an intrinsically safe construction in the direct control system, the invention provides for safety elements 5-5<n> which are connected in series with the solenoid valves 7-7<n> to be directly controlled. These safety elements 5-5<n> have the capacity to react very quickly to short circuit, earthing and closing against positive supply voltage and to interrupt the power supply to the solenoid valves 7-7<n> so that the solenoid valves 7-7<n> can only be loaded with intrinsically safe electric circuits. <IMAGE>

Title: Rotating mechanical seal
IPC: F16J15/36
Filed: 1983-09-24
Granted: 1984-06-14
Abstract: A rotating mechanical seal, which is intended to separate three media between rotating and fixed parts and is provided, in particular, for sealing off the output shaft (2) of electric motors with an oil chamber (3) positioned ahead of them, comprises at least one slip ring (8), which is secured firmly and leaktightly on the rotating part (2), and two counter-rings (9, 10), which, on the one hand, rest leaktightly against the slip ring (8) and, on the other hand, are sealed off relative to in each case one housing passage (12, 13). In order to be able to install and remove such a rotating mechanical seal with as little as possible effort, the two counter-rings (9, 10) are surrounded by a common outer sleeve (11) and held on the latter. In this arrangement, the outer sleeve (11) bridges the gap between the two housing passages (12, 13) and is sealed off relative to the respective housing passage. The interspace between the outer sleeve (11) and the respective counter-ring (9, 10) is bridged using a seal element, preferably a rubber-bellows cover (40, 41). The slip ring (8) is mounted on a supporting sleeve (16). This gives a compact rotating mechanical seal as a self-contained assembly unit ready for installation and comprising relatively simple components. <IMAGE>

Patent DE-3540019-C1 (DE)
Title: Thermal imaging camera
Inventor: DIEHL CHRISTIAN
IPC: H04N5/33
Filed: 1985-11-12
Granted: 1987-02-12
Abstract: In a thermal imaging camera having a cooled detector and a non-cooled lens which projects a thermal image on the same, the inner walls of the lens mount are silvered in the region of the thermal radiation to be detected and are designed and arranged such that they retroreflect the detector on to itself. For this purpose, the parts of the inner walls which face the detector are constructed as punctured spherical cups which are open in the direction towards the detector and whose centres of curvature lie in the detector plane. This permits a substantial reduction in stray light due to the characteristic radiation from the parts of the mount and stop of the lens.
Patent DE-3710699-C1 (DE)
Inventor: BRUNNER RUDOLF
IPC: F15B11/16
Filed: 1987-03-31
Granted: 1988-08-18
Abstract: In such control devices, the monitoring valve switches off the supply controller at the pressure or stroke limit or it limits the effective volumetric flow. The monitoring valve does not tell whether the consumer has actually exceeded or fallen short of the pressure or stroke limit, because it responds independently of the operating direction of the consumer. The novel control device is to directionally monitor the consumers. To directionally monitor the consumers (V), the control line branch (34) is constantly attached via the relief control line (36, 37, 38) to the displacement control slide (S1 - S5) and in the interior of the same can be attached directly to the tank solely in a control position (a or b) in which the consumer has been loaded in a direction in which it exceeds a predetermined pressure or stroke limit in the group of consumers. Although the monitoring valve responds, the relieving or limiting function only comes to bear if the displacement control slide reaches a control position in which the consumer would move in a direction in which it exceeds the pressure or stroke limit. On account of the directional monitoring of the consumers, the control device is suitable, for example, for the simultaneous control of various operating cylinders and hydraulic motors in mobile cranes.   <IMAGE>

Title: Method for cleaning service water systems or heating installations and device for carrying out the method
Inventor: KAMP OTTO
IPC: F24D19/00
Filed: 1987-04-22
Granted: 1988-12-08
Abstract: A method for cleaning service water systems or heating installations to which overpressure is applied from a central supply is characterised in that   a) by separation from the central supply (9) and simultaneous opening of the service water system (23) or of the heating installation, the overpressure is suddenly reduced, specifically in such a way that there is a slight evacuation against the direction of flow in operation; b) closure is performed again after a short time and the overpressure builds up; c) the operations of pressure relief and pressure application are multiply repeated successively, and   d) these operations are performed under automatic control.   In the device for carrying out the method, there is arranged in a main line (10) between the central supply (9) and the service water system (23) or heating installation a three-way valve (24) which can be adjusted by means of a motor (27) provided with a controller (28).   <IMAGE>

IPC: F01L1/32
Filed: 1988-06-03
Granted: 1989-06-01
Abstract: Rotation of the exhaust valve (13) in conjunction with the inclined end face (19) of the valve stem (14) induces a wobbling movement of the valve stem (14) within the limits of the play in the stem guide (15). The resultant continual intermittent contact between the valve stem (14) and the valve guide (15) prevents combustion residues being deposited on the valve stem (14). <IMAGE>

Date Aug. 22, 1991.Arrangement for the transfer of a paper web from the press section 10 to the dryer section 20 of a paper machine, where a water-absorbent felt belt 11 of the last press 13, 14 has at the same time the function of a transfer felt 11; i.e., the transfer felt 11 transports the paper web 9 from the press section 10 to the dryer section 20. There, the transfer felt serves to force the paper web onto at least the first drying cylinder 21. This drying cylinder and additional drying cylinders 22 lie therefore outside the continuous loop of the transfer felt 11.

Abstract: A radiation system, a capillary lens, on the basis of total reflection, is presented for the emitted radiation from an X-ray source. The capillary lens consists of a bundle of symmetrically arranged capillaries which lie alongside one another as though in an image conductor system. Apart from the angle of total reflection, which depends on the wavelength or the energy, the ratio of the radius of curvature and the radius of the clear diameter (gamma-value) of a capillary considered is decisive for the transmission of the X-ray beam.
