Patent DE-3322124-A1 (DE)
Title: Cage-mounting device for a heat-exchanger-tube purging element
Inventor: BARON WALTER JOSEPH
IPC: F28G1/12
Filed: 1983-06-20
Abstract: A heat exchanger has a multiplicity of tubes through which fluid flows and which are mounted in the vicinity of their ends by means of tube plates. Purging elements are designed in such a way that they can be moved back and forth and to and fro in the tubes, and that they are caught with the aid of cages. A cage-mounting plate is arranged outside immediately adjacent to the outer tube plate surface. The plate and its mounting interact with the tube plate in order to keep the cages in a fixed position relative to the tube plate and the tube ends.
Patent DE-3328789-A1 (DE)
Inventor: SCHLITTER GEORG
IPC: B66C13/56
Filed: 1983-08-10
Abstract: Suspended moving control unit (2) for hoisting appliances with switches (5) and color bands (6) on the casing, as well as directional color arrows for the logic connection of the control process arranged on the hoisting appliance (for example a bridge crane (7)) and which are of the same color as the switches (5) and as the bands (6) of the casing. Experience has shown that the operator never benefited by any visible marking on the control unit (2) and the hoisting tool enabling him to safely recognize before actuating a switch (5) the displacement direction of the hoisting tool. The control unit (2) is suspended to a rope or to a chain (3) attached to the crane; thereby, it is possible to rotate it by 90<o> or 180<o> about the axis thereof, which consequently switches the displacement directions of the crane track and of the rolling hoist, to oppose them. For this reason, the arrows represented on the key-switches (5) lose their "meaning". This "novelty" according to the present invention gives the operator a general optimum view in the room while enabling him to avoid false operations and to considerably reduce the "risk of accident".

Title: Method for determining a magnetic field
Inventor: PFANNSCHMIDT FRITZ DIPL ING
IPC: G01R33/04
Filed: 1983-11-25
Abstract: A method for determining a magnetic field, especially the earth's magnetic field, is described. To this end, an annular-core probe having a primary winding and two secondary windings, which are arranged symmetrically and at right angles to one another, is used. The drive voltage is a square-wave AC voltage which remains at zero for a defined time during the zero crossover. The delay time corresponds approximately to the positive pulse time and/or to the negative pulse time. A low circuitry cost with an improved efficiency at the same time are hence achieved in an advantageous manner in comparison with the normal triangular-waveform pulse control.

Abstract: The invention relates to a two-layered profiled-plate composite floor for buildings. The composite element comprises two profiles folded differently in their longitudinal direction, used firstly as a space-enclosing formwork profile at least partially protected on the outside against corrosion, and secondly, ungalvanised on both sides and offset in height, as a reinforcement profile, and comprises an in-situ concrete which envelopes the reinforcement profile on all sides and has a concrete topping. The central, covering profile construction of the formwork profile and reinforcement profile forms the main element, the end parts in the following planning grid unit spacing, which run out in variously angled-off fashion and are mounted in overlapping fashion, producing the anchor connecting element. The composite floor is laid and held by the clincher-built method. At a time when wages, the procurement of basic materials for galvanising and the associated dependence on imports constitute a significant cost factor as far as the national economy is concerned, the invention is aimed at using improved reinforcement by use of black plate, an appropriate profile design and utilisation of the strengthening of the reinforcing profile which can be achieved by bead formation, improved rigidity of the construction by mutual support of the formwork and reinforcement profile and, for asborbing horizontal stresses, a shearing surface which can be increased by recesses, and consequently creating a type of floor construction which to the greatest extent ...

Title: Method for depositing and stacking sheets, especially folded sheets
Inventor: VITS HILMAR
IPC: B65H33/02
Filed: 1984-06-19
Abstract: The invention relates to a method and an apparatus for depositing and stacking sheets, especially folded and printed sheets. The sheets are successively transported to a point of deposition and deposited on a supporting element B which can be lowered. The lowermost of the loosely deposited sheets are separated from the other sheets by insertion of a separating and supporting element. The partial pile formed in this way is lowered and compressed from above by means of a pressing element, and, once the supporting element has been removed, added under pressure to the sheets which are already held by another pressing element working alternately with the first pressing element and are used to form a packet. In this way and by these means, as the sheets are continuously deposited at the stacking point, the lowermost sheets of the loosely deposited sheets are in each case separated from the other sheets and fed to the sheets held under pressure, until enough sheets have been assembled to form a packet. <IMAGE>

Title: Arrangement for detecting the skidding or slipping of the wheels of rail traction units without running axles
Inventor: HAHN KARL DIPL ING
IPC: B60T8/62
Filed: 1984-11-02
Abstract: In order to achieve a more rapid engagement of the anti-skidding protection and to be able to evaluate the differences in the speeds of rotation of the axles with respect to the pseudo running axle without a tolerance threshold, it is proposed according to the invention that each wheel axle be assigned a separate integrator whose output voltage is compared with a voltage corresponding to the associated axle speed, that an additional comparison of all the axle speeds with one another be carried out with formation of minimum values via a minimum value former during travel (or formation of maximum values when braking), that this minimum value formed be increased (lowered when braking) by a value which takes into account the permissible differences in the wheel diameters and serve as a reference variable for all the integrators, and that the individual integrators be reset by means of minimum value stages to minimum values (maximum values when braking) between this common reference variable and the speed of rotation of their associated axle. <IMAGE>

Title: Hand gun or pistol having a safety device
Inventor: KLOSE DIETER
IPC: F41A17/06
Filed: 1984-12-17
Abstract: The hand gun or pistol has a safety device which normally blocks the firing mechanism and/or hammer mechanism and can be unlocked only by entering individual-specific data and/or control signals. These control signals, with individual coding, can be produced by a transmitter which is carried on the body of the owner, for example in a wristwatch (14), and are transmitted from its antenna over the skin to a receiver (10) which is installed in the weapon. After reception of the control signals, the receiver (10) operates one or more electromagnets which unlock the mechanical locking elements of the safety device and hence arm the weapon. The transmitter in the wristwatch (14) is activated, in the case of the example, by means of a combination lock (16). The latter is automatically returned to its locking position, which switches off the transmitter, when the wristwatch (14) is removed. <IMAGE>
