Title: Covering cap for openings in housings
Inventor: HOFMEISTER WERNER
IPC: H05K5/03
Filed: 1981-12-04
Abstract: A covering cap for openings in the housing of apparatuses which have to be adjusted is proposed, which cap can be removed without damage only by maintenance-service workers and, in the case of which cap, manipulations by unauthorised personnel can be identified. The covering cap (6) has latching levers (17) with latching tabs (20) which are latched to the inner wall of the housing (2), and unlocking cams (19) by means of which, for complete removal of the covering cap (6) out of the opening (5) in the housing (2), the latching tabs (20) behind the housing inner wall are pivoted forward from the opening (5) of the housing (2) through an unlocking collar (24) of a withdrawal bolt (7), in order to remove the covering cap (6) completely from the housing (2). The withdrawal bolt (7) at the same time destroys a membrane (9) in the head (8) of the covering cap (6). However, after carrying out service work on the structural element (4) to be adjusted, the maintenance-service worker closes the opening (5) with a new covering cap (6) which he has available. <IMAGE>

Title: Underground preparation
Inventor: OFFERGELD WERNER ING GRAD
IPC: B03B9/00
Filed: 1982-05-05
Abstract: In coal mining, partial preparation of the run-of-mine coal takes place underground. In the process, the run-of-mine coal is graded underground into fine and coarse coal, the fine coal is then raised to the surface, and the coarse coal is comminuted, then sorted and likewise raised to the surface. In order to separate as large a portion of waste as possible from the run-of-mine coal underground, the invention provides for the run-of-mine coal to be screened at 15 or 20 mm, for the grain above 120 mm to then be comminuted and, after the sorting, i.e. after the waste is separated, to be conveyed with the fine coal to the surface or for the segregated waste portion to be conveyed to the stowing-material bunker. <IMAGE>

Title: Method and devices for local control of heating surfaces through which liquid flows and for measuring the heating work
Inventor: ESDORN HORST PROF DR ING
IPC: G01K17/10
Filed: 1983-04-02
Abstract: The invention relates to a method and devices for local control of heating surfaces through which liquid flows and for measuring the heating work. The output of heating surfaces through which liquid flows depends on parameters specific to the heating surface (heat transfer conditions between heating medium and space, size of heating surface, arrangement in space, etc.), as well as on the respective operating conditions (liquid feed temperature, mass flow, room temperature). Local control of capacity is generally performed by varying the liquid mass flow. It is the aim of the invention to undertake ON/OFF control of the heating surfaces. A constant heating medium mass flow is ensured by suitable measures (bypass valves or volume flow governors). The difference between the feed and return temperatures is measured simultaneously. The magnitude of the heating medium mass flow under the particular installation conditions can be determined by measuring the temperature difference between feed and return and the room temperature in a "calibration trial". By counting the ON pulses of the control, which works with the same pulse durations, it is possible in conjunction with simultaneous multiplication by the actual temperature difference between feed and return to make an accurate measurement of the instantaneous heating capacity or of the heating work of the heating surface. DDC control with the aid of microprocessors offers particularly effective conditions for applying the method. In terms of rooms and dwellings ... Original abstract incomplete.

Title: Furniture lock which can be used with a plurality of different modes of fastening
Inventor: MOELLENKAMP SIEGFRIED
IPC: E05B63/04
Filed: 1983-05-04
Abstract: The invention relates to a preferably mounted-on furniture lock with a central keyhole (6), which can preferably be used for all modes of fastening, namely on the right, on the left, at the top and at the bottom, but not exclusively for these. The lock assembly is designed virtually completely symmetrically to the transverse mid-axis (15) of the lock. The tumbler (17) is materially in one piece and is mounted in a floating manner relative to the transverse mid-axis (15) of the lock by means of a spring element (23). A possibility is shown how, with a hollow-bored stalk-type key customary in the sector, that is to say commercially conventional, a lock with a central keyhole (6) can be made capable of use for a plurality of modes of fastening by means of a key-pin rocker (33) which allows a plurality of key pins (35 and 36) to be disengaged and engaged (Figure 2). <IMAGE>

Title: Rotating electrical machine having an oblique air gap
Inventor: STEVANOVIC MILAN
IPC: H02K1/06
Filed: 1983-05-18
Abstract: A rotating electrical machine having an oblique air gap between the stator and rotor, with an inclination angle  alpha  = 25 DEG -155 DEG or 205 DEG -355 DEG with respect to the rotation axis of the shaft of the rotor, makes possible a reduction in the magnetisation current and hence also an improvement in the machine utilisation factor. This is achieved by reducing the air gaps. The new design furthermore produces improvements with respect to shortening and reducing the size of the shaft diameter (material saving), reducing the cross-section of the electrical conductors while improving the cooling, reducing the insulation-voltage level, and improving the starting torque and the current. It furthermore raises the possibility of simplifying production of the pole cores. <IMAGE>
