Patent DE-3601349-A1 (DE)
Title: Lip seal ring
Inventor: LIETHEN WILHELM
IPC: F16J15/3248
Filed: 1986-01-18
Abstract: In order to improve and seal permanently the connection of a sealing component consisting of one or more discs of polytetrafluoroethylene or soft material of a related type, in the case of a lip seal ring with sealing component clamped into a housing the sealing component is split in the clamped-in bonding component and a ring made of elastically deformable material is inserted into the gap or between two sealing discs which rest one on the other. By means of this arrangement, the elastically deformable ring is deformed even under small clamping-in forces and presses the sealing component material into the receptacle in a sealing fashion. As a result of the small clamping-in forces, the sealing component material is stressed to a relatively small degree and its plastic flow is reduced to a minimum, and the ring made of elastically deformable material which is preferably an elastomer is particularly well protected against being affected by the sealing medium. The lip seal ring thus brings about a permanent, good seal in its bonding component by virtue of its high resistance properties. <IMAGE>

Title: Refractory lining, in particular for combustion chambers of gas turbine installations
Inventor: MAGHON HELMUT
IPC: F27D1/14
Filed: 1986-07-24
Abstract: The refractory lining, in particular for combustion chambers of gas turbine installations, consists of individual bricks (1) which, leaving cooling fluid gaps, are fastened on a support structure (11) in a virtually surface-covering manner by metal holding clamps (31). The bricks (1) have in this case, at least on the sides which are held by metal clamps (31), flanks (3) which are bevelled towards the support structure (11) and which are at least partially covered by the likewise bevelled holding clamps (31). The holding clamps (31) are, sprung by a spring element (26), fastened on the support structure (11) so that they press the bricks (1) against the support structure (11). The hot side (37) of the holding clamps (31), which in the case of this form of construction is particularly thermally loaded, is cooled via cooling fluid openings in the support structure (11) and a bore (22) in the screw (21) directly and by a cooling film. The lining according to the invention is easy to mount and, as a result of the special shape of the bricks (1), barely tends to suffer damage as a result of changing thermal loads. <IMAGE>

Patent DE-3713203-A1 (DE)
Title: Surface heating
Inventor: HAASE GEORG
IPC: F24D13/02
Filed: 1987-04-18
Abstract: Surface heating, for example, floor heating with spiral-, meander- or register-shaped heater wires placed in a sealing compound of a concrete coating have a relatively great construction height and are not immediately suitable for later installation in old buildings. The heat storage capacity is too great and the control behaviour is too sluggish. In order to be able to use surface heating even in old buildings, as heater lines (for example, copper pipes or electric heater wires) lines with a diameter not greater than 8 mm are used, and the sealing compound consists of metal powder (for example, aluminium granulate or powder) and a binder (for example, epoxide resin) in an application height on average not exceeding 10 mm. Because of the better heat conductivity of the new surface heating and its better regulation behaviour, it is possible to save energy, and alternative energy sources with a low temperature level can be used to an increasing extent.

Title: Ultra-fast control valve
Inventor: BONIN ECKARDT VON
IPC: F02M59/46
Filed: 1987-04-24
Abstract: Electrically operated ultra-fast valve with a drive consisting of stacked piezoelectric elements. Control valves which are operated by means of a coil with a core and armature are too slow to achieve short operating times for the switching devices for high, medium and low voltages. The use of piezoelectric elements capable of rapid switching fails to produce the desired result because the valve opening achieved is too small, even where a stack of 50 elements is used. The invention makes available a valve with a drive comprising stacked piezoelectric elements, in which an increase in the stroke is achieved by virtue of the ratio of the top surface of the stack of piezoelectric elements (11) to the piston area of the valve tappet (5) and by means of a hydraulic space (10) arranged between these elements. <IMAGE>

Title: Method and device for straightening weft threads in fabrics
Inventor: EPPLE HELMUT
IPC: D06H3/12
Filed: 1987-05-06
Abstract: A method and a device for straightening weft threads in fabrics are indicated. In these, a fabric web running through is tensioned over a specific length portion with a force increasing in the running direction, essentially in the weft direction, between two tensioning drums which are located at the edge and which can be moved independently of one another in such a way that differing forces occurring during skewing and exerted in the running direction on the tensioning means can be compensated, so that the skewing is eliminated. It is proposed to drive the tensioning means in such a suitable way that the frictional forces necessarily occurring do not have to be overcome by means of drawing-off forces in the fabric web, so that no curved drafts occur.

Patent DE-3716285-A1 (DE)
Inventor: HEGELER WILHELM
IPC: G08G1/09
Filed: 1987-05-15
Abstract: In an arrangement for decoding signals which are received in addition to other signals as a modulation of radio waves and whose respective frequency constitutes a specific item of information, a time basis signal of constant frequency is generated from which a reference signal with a controllable frequency position and phase position is derived with the aid of a microprocessor. An output signal is derived if there is a coincidence of the reference signal with the received signal with respect to phase and frequency. The time basis signal can preferably be derived from the instruction frequency of the microprocessor by running through program loops of identical length at least in the timing means. A register which is incremented by changeable values serves for deriving the reference frequency. In the case of two superimposed signals, the one is evaluated with respect to frequency and the other with respect to the pulse duty factor of a binary signal. <IMAGE>

Title: Method for regulating a cage stranding machine
Inventor: CLASSEN HELMUT DIPL ING
IPC: D07B3/06
Filed: 1987-07-23
Abstract: Cage stranding machines have hitherto been operated at a constant rotational speed. However, as a result of unavoidably uneven windings of the reels used, torques induced by centrifugal forces act on the reels, become noticeable directly as tensile stresses in the individual wires and lead to wire breaks when the cage stranding machines are operated at their nominal rotational speed. Consequently, cage stranding machines can be operated only at a reduced rotational speed and have a lower production capacity. In order to overcome this disadvantage, the centrifugal force acting on at least one reel body is measured, and, as a function of a predeterminable constant centrifugal-force value, the rotational speed of the stranding cage is increased to the maximum permissible cage rotational speed which can then be maintained until the complete stranding of the wire stock on the reels. This regulating method leads to a considerable increase in the possible production capacity, along with an improved quality of the stranded material.
