Patent DE-3105915-A1 (DE)
Title: Barrier for preventing undesired air penetration through a heating system which is not in use
Inventor: KOHL HANS
IPC: F23L3/00
Filed: 1981-02-18
Abstract: The blind-type damper constitutes a possible contribution to energy saving in the household and in industry, where oil or gas heating systems are used. The idea of the blind-type damper is nothing radical in itself, but what is new is its consistent use in the heating sector. Owing to the sealing of the dampers with respect to one another and the lateral sealing by means of bearers, values of "tightly closing" dampers may be achieved. The cost factor is fundamental as basis for an improvement of the existing system, but is also essential for new constructions.

Title: Spring-loaded hinge
Inventor: LAUTENSCHLAEGER GERHARD
IPC: E05D11/10
Filed: 1981-04-28
Abstract: Spring-loaded hinge (10) for the pivotable articulation of the door on the supporting wall of a piece of furniture. The hinge (10) consists of a door fastening part, in the form of a mortice insert (18), coupled in the manner of a four-bar linkage by way of two hinge links (14, 16) to a supporting-wall fastening part in the form of a supporting arm (12).

Title: Steep-taper tool holder
Inventor: JUNG LIEBHARD
IPC: B23B31/12
Filed: 1981-09-11
Abstract: The steep-taper tool holder, suitable in particular for numerically controlled machine tools, has a housing (5), provided at the end with a taper shank (3), as well as a multi-jaw chuck (7), the chuck jaws (15) of which axially facing the taper shank (3) and arranged around the taper axis can be moved radially towards one another along guide surfaces (17), inclined towards one another, of the housing enclosing the chuck jaws (15). A first spindle drive (19) with an axially movable thread element (21) acting on the chuck jaws (15) meshes with a spindle nut (29) which is rotatably supported on the housing (5) via a power amplifier (33). Held on a bearing part (35) of the power amplifier (33) is a second spindle drive (55) which has a threaded element (53), firmly connected axially to the bearing part (35), and an axially movable threaded element (59) meshing with the threaded element (53). The axially movable threaded element (59) acts on a drive member (77) of the power amplifier (33), the drive member (31) of which can axially displace the spindle nut (29) of the first spindle drive (19), which spindle nut (29) is otherwise connected to the bearing part (35) of the power amplifier (33) in such a way as to be locked against rotation. The axially movable threaded element (59) of the second spindle drive (55) is connected via a torque coupling (67) to the bearing part (35) and thus to the spindle nut (29). Below a predetermined drive torque provided by the torque coupling (67), the spindle nut (29) is turned via the turning handle (73), as a result of which the multi-jaw chuck (7) is closed via the spindle drive (19). If the drive torque exceeds the value at which the torque coupling (69) disengages, the axial movement of the movable threaded element (59) of the spindle drive (55) is converted via the power amplifier (33) into an axial movement of the spindle nut (29) clamping the multi-jaw chuck (7) in a power-amplified manner. <IMAGE>

Title: Method for producing high-voltage insulations on winding elements of electrical machines
Inventor: SPERLING KLAUS ING GRAD
IPC: H02K15/12
Filed: 1981-09-26
Abstract: In order to simplify a method for producing high-voltage insulations on winding elements of electrical machines consisting of wound, highly resinous, thermally curable prepreg strips containing mica, the insulated winding elements are evacuated and degassed by means of a vacuum process in a vacuum container, after which they are completely covered, while maintaining the vacuum, with a blocking fluid having a low vapour pressure and a relatively high boiling point, they are then pressure sealed without cavities, by ventilating the container or applying overpressure, and are subsequently thermally cured, outside the blocking fluid, at normal pressure or overpressure. Impregnation of the insulated winding elements is thus no longer necessary. <IMAGE>

Patent DE-3144464-A1 (DE)
Title: Self-centring bearing for a rotating body
Inventor: TITTIZER GABRIEL DIPL ING
IPC: F16K5/06
Filed: 1981-11-09
Abstract: A bearing which ensures uniform (e.g. thermal) expansion around the axis of symmetry (CD) of a body (1) which can rotate about an axis (AB) (e.g. a valve plug in gas lines for high-temperature nuclear energy installations). The bearing journals (2, 3), which are arranged such that they can move longitudinally in bearings (4, 5), are kinematically (6, 9) connected to in each case two pistons (7, 8 and 10, 11, respectively), which are coupled rigidly to one another and can force an incompressible fluid out of the associated cylinders (12 to 15). The cylinders are connected to one another via compensating lines (16, 17) in a crossing-over manner such that a movement of the one bearing journal (2) in the one direction corresponds to an opposite movement of the other bearing journal (3) of precisely identical magnitude. The bearings (4, 5) are for their part supported spherically in bearing shells (18, 19) such that tilting of the bearing journals (2, 3) with respect to the rotation axis (AB) can be allowed. <IMAGE>
Patent DE-3148258-A1 (DE)
Title: High-voltage installation
Inventor: BESSEI HERBERT DR ING
IPC: H01H33/22
Filed: 1981-12-05
Abstract: A gas-insulated high-voltage installation for electrical equipment is filled with a mixture of a gas, composed of an insulating gas, and the vapour of a liquid. The interior of the switching installation is connected to a liquids container, which can be cooled and expediently is heat-insulated, so that the vapour of the liquid can balance in the two spaces. The temperature of the liquid is controlled in such a way that the desired working gauge pressure of the encapsulation results from the total of the partial pressure of the insulating gas and the vapour pressure of the liquid. The invention makes it possible to keep the working gauge pressure of gas-filled encapsulations approximately constant over a wide temperature range at low cost in space and energy.

Title: Panoramic radiography method and apparatus for carrying it out
Inventor: MUSAPH FREDDY WOLF DR
IPC: G01G19/44
Filed: 1982-10-02
Abstract: The invention relates to a method and an apparatus for panoramic radiography, in particular of the skull or tooth region, for optimum determination and control of radiation matched to the patient, taking into account the radiation dose which is absorbed by a patient and the derivation of adequate information from the selected region which is to be irradiated. The invention is based on knowledge that the attenuation is dependent on the amount of substance in the region through which the radiation passes. Correct irradiation can be achieved in this manner by regulation of the radiation intensity and/or the radiation time by using the patient's weight as a control parameter. A patient (P) can preferably be weighed, for example using electronic scales (6), a signal representing the weight being input into a system (5) for controlling the radiation on the object on which the radiography is to be carried out in order to achieve radiation which is as optimum as possible for the selected region which is to be irradiated. <IMAGE>

Patent DE-3303689-A1 (DE)
Title: Determination of the dose or dose distribution in beam-crosslinked polyolefins
Inventor: ANDRESS BERNHARD DR
IPC: G01T1/04
Filed: 1983-02-03
Abstract: To determine the radiation dose or dose distribution in electron-beam-crosslinked polyolefins, use is made of a method in which the crosslinking takes place in the presence of an additive which is incorporated in the polyolefin during irradiation. After crosslinking, the portion of the additive not incorporated is dissolved out of the polyolefin and the total absorbence of the polyolefin is then determined photometrically. This method makes it possible, in particular, to assess the quality of the irradiation conditions during electron-beam crosslinking of polyolefin-insulated medium-voltage cables.

Title: Capacitive isolating element
Inventor: WENDEL WOLFGANG
IPC: H01R13/646
Filed: 1983-05-11
Abstract: In a capacitive isolating element which is constructed as an intermediate plug having two coaxial plug connections which can be mounted adjacent to one another by means of a screw sleeve, in order to connect two coaxial radio-frequency lines, the inner conductors of the plug connections are connected to one another via a capacitor, and their outer conductor parts are connected to one another via a rim of capacitors arranged in the form of a ring, for isolation in DC terms. In order to achieve a construction which is as simple and cost-effective as possible, with high broadband levels for the return loss and screening effectiveness, the plug connections can be connected by means of in each case one inner and outer conductor contact piece, which is isolated therefrom, which contact pieces have an approximately constant diameter ratio, without discontinuities, over their entire length with respect to one another and in each case consist of two parts which are permanently connected to one another via the capacitor or the capacitors, and are constructed symmetrically with respect to the radial centre plane.
