Title: Method for determining the rated output for a heat generating apparatus tuned to the heat requirements (demand) of a heated object
Inventor: AMRHEIN WILHELM ING GRAD
IPC: G01K17/06
Filed: 1986-08-02
Abstract: In the method, a determination is made in a known way of the quantity of heat which is output by a heat generating apparatus to the heated object during a specific observation period in which it is in use. The result of the determination is divided by a desired number of operating hours, which is stipulated for a modern heat generating apparatus of high efficiency for the observation period and for the heated object. The observation period is subdivided in accordance with the invention into individual measurement periods, and the desired number of operating hours is stipulated with reference to the measurement period as a function of the external temperature. The result of this is that even measurements from a comparatively short observation period yield useful results, and that user habits are also determined. <IMAGE>

Patent DE-3643781-A1 (DE)
Title: Belleville spring
Inventor: BEST DIETER
IPC: F16F1/32
Filed: 1986-12-20
Abstract: Slotted belleville springs are known which consist of an annular disc with spring tongues arranged radially and distributed over the disc circumference, each extending at an acute angle to two spring contact planes and having spring elasticity in an axial direction perpendicular to the contact planes. These known belleville springs have the disadvantage that automatic installation is possible only with very expensive means, particularly since its spatial alignment has to be accurately maintained. It should be possible to install the new belleville spring either manually or automatically without errors and by simple means. In the case of the new belleville spring (1) two circumferentially adjacent spring tongues (3) in each case extend in different directions away from the centre plane (6) at an acute angle, starting from the said centre plane (6), the centre plane being defined by the annular disc (2) and being parallel to the contact planes (11a, 11b).   Applications: tolerance and play compensation in rolling bearings etc. <IMAGE>
Patent DE-3643784-A1 (DE)
Title: Screwdriver
Inventor: RIXEN EDGAR
IPC: B25G1/06
Filed: 1986-12-20
Abstract: A screwdriver with a handle (1) and a blade (2) is shown. The blade can assume two working positions in the handle. In the first position, the blade (2) lies coaxially with the longitudinal axis of the handle, that is to say in the position known from the conventional single-purpose screwdriver tool. In the second position of the blade, the handle (1) is set transversely. In this position, too, the blade again projects centrally from the handle. The two working positions can be obtained by pivoting or refitting the blade (2). The blade is locked in both working positions. The locking mechanims (18, 19, 63, 64) secure the blade against unintentional pivoting. In the case of a version of the blade (2) which is pivotable in the handle (1), all means (51) for securing the working position of the blade can be provided in the pivot pin (3) which is pivotable in the handle. The blade is held indirectly in the handle by the pivot pin. In the case of the refitting version of the blade, two bushes are provided in the handle, into which the blade is alternately inserted. <IMAGE>

Title: Cyclic process for extracting technical work from the earth's gravitational field
IPC: F03B17/00
Filed: 1987-05-14
Abstract: The invention concerns a cyclic process for converting gravitational field energy into technically utilisable energy by means of a liquid mass, e.g. water, guided vertically in a cycle, in particular for driving water turbines, and for generating electricity in stationary power stations via electrical generators. The precondition for extracting technical work from the earth's gravitational field is that the mass of liquid to be accelerated reaches a higher speed and thus a higher kinetic energy due to gravity than a solid mass of equal weight, e.g. a metal ball, would reach from the same height of fall. This precondition is achieved according to the invention with a liquid mass, e.g. water, by accelerating it vertically downward one after another and independent of one another by means of gravity, on the basis of the superposition principle. This is done by first accelerating it from a state of rest out of a round opening in the bottom of a storage vessel at constant gravitational pressure head ho with the gravitational pressure acceleration ao (ao > g) to the static initial velocity vo, and then the resultant jet of liquid in a guide tube open on both sides with a cross-section continuously adjusted to the speed of fall ...

Title: Seal for a grinding machine
Inventor: SETZER HERBERT
IPC: B24B5/04
Filed: 1987-09-16
Abstract: There is provided a seal for a grinding machine, in which a grinding spindle is capable of moving relative to a workpiece in a horizontal plane. The grinding spindle drives a grinding wheel rotatable about a horizontal axis and is arranged on a swivel plate (50) rotatable relative to a baseplate (19) about a vertical axis (25). The seal (80) is arranged at the periphery (60) of the baseplate (19) and seals the latter off from the swivel plate (50) during the swivelling movement. In order to prevent the penetration of grinding sludge (swarf) (64) into the inner space between baseplate (19) and swivel plate (50) and to reduce the frictional resistance in the region of the seal (80), the seal (80) is equipped with at least two upward-pointing lips (82, 83, 84), of which the radially outer lip (82, 83) has a lower height (h2, h3) than the radially inner lip (h3, h4). The swivel plate (50) reaches, by at least one downward-pointing annular shoulder (71, 73), contactlessly into the interspace (96, 97) between the lips (82, 83, 84). The annular shoulder (71, 73) ends at a height (h8, h9) below the height (h2, h3) of the radially outer lips (82, 83). A liquid (90) can be introduced into the interspace (96, 97). The radially outermost lip (82) is adjacent to the outer space (Fig. 3). <IMAGE>

Title: Stepping motor with a permanent-magnet phase
Inventor: RAUCH MANFRED PROF DR SC TECHN
IPC: B41F13/004
Filed: 1987-10-22
Abstract: The invention relates to a stepping motor with a permanent-magnet phase which is used for converting discrete electrical signals into mechanical movement. It is characterised in that one phase is activated by permanent magnets, without any electrical excitation. It can be used advantageously especially wherever mechanical positioning tasks are characterised by long and frequent dwell times, such as in the case of printer roller drives, moving drilling heads, etc. The aim and object of the invention are to develop a stepping motor which can produce a holding force at rest without having to use energy continuously to do so. According to the invention, the stepping motor has a continuously permanent-magnet-excited phase magnet system and further phase magnet systems which can be excited electrically and whose pitch offset deviates in a defined manner from their phase angle. Only the permanent-magnet-excited phase magnet system acts when no current is flowing. When current is flowing through a phase magnet system which can be excited electrically, its effect is added to that of the permanent-magnet-excited phase magnet system, so that the corresponding phase is adjusted.
