Title: High-temperature pipe clamp
Inventor: GAESSLER HEINZ DIPL ING DR
IPC: F16L59/135
Filed: 1984-06-05
Abstract: The invention relates to a high-temperature pipe clamp having a lower retaining shell and an upper retaining shell which essentially have an internal contour in the form of a cylindrical jacket and having a diameter which is designed for the thermal expansion in the operating state of the pipe which is to be retained, and are held together on lugs, said clamp having a heat insulation layer which is arranged on the inner circumference of the retaining shells and consists of insulating blocks, and having holders, which are fitted externally on the retaining shells, for supporting or suspension devices. In order to create a high-temperature pipe clamp which can be installed at a reduced cost and which is able to absorb impact forces coming from the pipe to a considerable extent, it is proposed that, without damaging the insulating-block filling, the two retaining shells (1, 2) be designed in each case as frame structures having two supporting belts (12), which are bent approximately in the form of semicircles and are arranged parallel to one another, at a distance, at the two ends of the retaining shells (1, 2), that the supporting belts (12) be connected on their external circumference by means of a cover (3), which is bent into the form of a half-cylindrical jacket, that sprung pressure-transfer elements (4, 10, 11) be arranged between the layer of the insulating blocks (7) and the internal circumference of the retaining shells (1, 2), and that the lugs (5) be rigidly connected to one another by means of unsprung screws. <IMAGE>

Title: Method and device for determining fracture depths by means of ultrasound
Inventor: CROSTACK HORST-ARTUR PROF DR I
IPC: G01N29/42
Filed: 1984-07-16
Abstract: The invention relates to a method and a device for determining the depth of fractures in workpieces, components, installations, apparatuses and other objects, ultrasonic pulses being introduced into the object to be tested and being received, converted, amplified and evaluated after reaction with the fracture. In order to be able to determine the fracture depth by means of ultrasound even when the shape, width and inclination of the fracture are not known, and when an unknown medium is present in the fracture, both on the inside and on the outside and on nonaccessible sites, according to the invention the acoustic irradiation of the fracture is performed using a specific type of wave, and from the fracture display obtained the transfer function is determined as a function of the frequency by setting up an amplitude spectrum from which a determination is made of the transition frequency f@ (from reflection to scattering) from which the fracture depth is calculated with the aid of the sound velocity and a constant which depends on the selected type of wave. In the device, there is connected downstream of the receiver test head a receiving unit which consists of a demodulator fed by the transmitter, a narrow-band filter having a peak value meter, and two separate memories and a comparator connected to these.

Title: Process for joining plastic and metal mount for plastic material
Inventor: MICHEL WOLFGANG
IPC: B31F5/08
Filed: 1984-08-18
Abstract: Process for joining plastic with metals as well as metal mount for plastics material produced according to the process. In the present process for joining plastics to metals of the same or different composition as well as the same or different thickness, first an electrically conductive direct bond is formed between the metals by spot welding at the points at which no plastic is arranged between the metals. Subsequently to this, the metals are spot-welded together through the plastic at a plurality of spot welding points. The plastic material can be in the form of plastic films or sheet-shaped rigid plastic. According to the process, one- or two-part mounts enclosing the edge of the plastic material lying between on both sides along a strip can be produced, an electrically conductive direct bond between the parts of the mount being formed at least at a point which does not enclose the plastic material. Furthermore, within the strip, the mount is electrically spot-welded through the plastic material lying between. <IMAGE>

Title: Setting-up system for offset printing machines
Inventor: BOSSE ROLF DR ING
IPC: B41F27/00
Filed: 1985-02-19
Abstract: The precise stationary and register position of an offset printing plate on the plate cylinder is achieved in that the front tensioning element is brought into an axially parallel position by adjustable stops, the printing plate is moved into a clear position relative to the impression cylinder or to the tensioning element by means of round register holes and register pins on the leading edge of the printing plate and is clamped in the front tensioning element. The printing plate is then tensioned on the plate cylinder without distortion by means of the contact pressure of the blanket cylinder beginning at the front, said plate cylinder having been set to a given diameter by means of a special self-adhesive film. Only then is the printing plate clamped in the rear tensioning element and the printing plate tensioned solely by means of the rear tensioning screws, the rear tensioning element being variable telescopically in the axial direction in order to be able to compensate any stretching of the printing carrier transversely to the printing direction by stretching or compressing the printing plates without dispensing with an even tensioning of the trailing edge of the printing plate.

Title: Switching unit for switch models in electrical telecommunications apparatuses
Inventor: DEICHMUELLER HORST DIPL ING
IPC: H01H15/02
Filed: 1985-05-06
Abstract: The invention relates to a switching unit for switch models in electrical telecommunications apparatuses. The aim of the invention is a switching unit having small dimensions, especially a small base area, and high contact reliability as well as comparatively simple automatic assembly and a low use of material. The object of the invention is to find a compact switching unit having a contact force which is as far as possible independent of lateral switching slide movement and whose elements are designed such that simple automatic assembly is possible using contact parts in strip form. According to the invention, contact elements which are in strip form and have solder connections on both sides are mounted on the outer walls of a cell which is formed by two identical supporting half shells, which contact elements have bends which project through eccentrically arranged perforations into the interior of the switching chamber, which is formed from the cell and contact elements, and there, together with sliding webs which are arranged between the perforations, form a sliding rail on which the switching elements slide, which switching elements are guided, located one on top of the other, in the switching slide, with play at right angles to the displacement direction. Such switching units are primarily used inside switch models in broadcast radio receivers. <IMAGE>
Patent DE-3520810-A1 (DE)
Title: Process for simplified throughput determination of vacuum cell filters (drum filters) using a balance
Inventor: LATSCH HERMANN DIPL ING
IPC: B01D37/04
Filed: 1985-06-11
Abstract: To calculate the throughput of a drum filter, the values kg/dm<2> of filter cake, m<2> filter surface area and minutes per drum rotation must be known. Since the constant stroke of the pivot apparatus generates horizontal traces on the filter cake and the speed of rotation of the filter drum determines the distance between traces (fields), the speed of rotation of the drum can be determined from the number of fields per cell. The scale division of the balance is configured in such a way that the filter throughput in t/h can be read off from the two variables kg/dm<2> of filter cake and F (fields per cell). The advantages achieved by the invention are, in particular, that to determine the throughput of the drum filter, neither a time-consuming time recording of the filter rotary speed nor a calculation from a formula is required. <IMAGE>

Title: Method for stringing rackets used in games, especially tennis rackets
Inventor: RICHTER JUERGEN
IPC: A63B51/00
Filed: 1985-06-13
Abstract: Whereas up to now attempts have been made to prevent deformation and fracturing of the frame by means of mechanical devices to hold the racket frame, the causes of frame fracturing and deformation are eliminated by a new method, which is characterised by the alternate stretching of longitudinal and transverse strings starting symmetrically in relation to their axes. As the number of cross-over points of the longitudinal and transverse strings is in inverse proportion to the string length, the most protective stringing is produced for the most highly loaded point of impact on the racket. As the string which has yet to be stretched becomes shorter and shorter as the number of cross-over points increases, this method results in an acceleration of the stringing process.
