Patent DE-3311015-A1 (DE)
Title: Hollow block
IPC: E04B2/02
Filed: 1983-03-25
Abstract: The invention relates to a hollow block having a lower and an upper bearing face, an inner and an outer visible face, two profiled abutting faces and in each case at least one profile elevation and recess for engaging into the abutting face of an adjacent hollow block, and also at least one hollow chamber running virtually perpendicular to the bearing face. The object of the invention is to provide a hollow block of the generic type with improved manipulability and without the need for additional handling to obtain the block orientation during block laying, for the purpose of connection to a block which has already been laid. This is achieved as a result of the fact that each abutting face is virtually axially symmetrical per se in relation to a substantially centrally running axis of symmetry, so that one half of the abutting face represents a virtually identical negative or positive image of the other half folded through 180 DEG  about the axis of symmetry, that the abutting faces represent, owing to an imaginary translation of the other abutting face in each case, the negative or positive image, and that the hollow chamber is closed by a cover plate at least at the upper or lower bearing face.

Title: Circuit arrangement for setting the phase angle of vertical synchronising pulses
Inventor: HINKEL LUKAS DIPL ING
IPC: H04N3/22
Filed: 1983-10-22
Abstract: Visual display units are used for optical displays in the case of video games, computers, processors and the like, to which units the vertical synchronising pulses, inter alia, are also supplied from the said units, as well as the actual video signal. Said synchronising pulses often have a non-standard position, so that the image of the visual display unit is displaced in the vertical direction. In addition, a portion of the video signal may even be masked out by the blanking pulse derived from the vertical synchronising pulse. In the case of the invention, the phase angle of the vertical synchronising pulse can be set by means of a delay circuit having a variable delay time, such that the time at which the synchronising pulse occurs is standard again. The non-standard synchronising pulse triggers a first monoflop which drives a second monoflop whose output pulse is differentiated. In this case, the differentiated trailing edge of the output pulse of the second monoflop supplies the vertical synchronising pulse which is located in the correct phase.
Patent DE-3402652-A1 (DE)
Title: X-ray intensifying screen
Inventor: DEGENHARDT HEINZ DR RER NAT
IPC: G03C5/17
Filed: 1984-01-26
Abstract: The invention relates to X-ray intensifying screens, in which rare-earth phosphors are used. With these intensifying screens, the object is to reduce the undesired image graininess caused by so-called screen noise, while maintaining image sharpness and intensifying action. According to the invention, this is achieved by admixing pigment particles (5) to the phosphor layer (2), containing rare-earth phosphors, in particular an yttrium sulphide phosphor (3), of the screen. The particles can consist of a very fine-grained barium silicate phosphor, which amounts to 0.5 to 5 per cent by weight of the phosphor of the phosphor layer and, under the action of X-rays on the intensifying screen, radicates UV light in the region of 351  mu m. Intensifying screens of the type according to the invention are particularly suitable for the medical X-ray imaging technique. <IMAGE>
Patent DE-3403001-A1 (DE)
Title: Heat exchanger
Inventor: ROCKENFELLER HEINRICH DIPL ING
IPC: F28F9/00
Filed: 1984-01-28
Abstract: A heat exchanger, in particular a charge air cooler, is proposed which has two lateral parts that are arranged at a distance from one another and are extruded profile sections. Arranged between the lateral parts are the tubes, which conduct a heat exchange medium, for example water, and transverse fins which are transversely penetrated by said tubes and on which a different heat exchanging medium, for example charge air, is applied. The tubes are firmly anchored at both ends in the tube plates, on which a box-like cover is mounted. Each lateral part has in the region of the free end faces a bead-like strip in which there is contained a continuous, groove-shaped receptacle having a @cross-section. Contained in the receptacle is a congruent engaging part which carries at both ends mounting bolts which penetrate the tube plate and cover at both ends and onto which the nuts for clamping together are screwed. The engaging parts contain threaded bores in which mounting screws which penetrate through the slot of the @profile engage for the purpose of mounting the heat exchanger on housing walls or mounting housing walls on the heat exchanger. The extruded profile sections of the lateral parts reduce production costs, the use of material and weight in a substantial fashion.

Patent DE-3408292-A1 (DE)
Title: Active suspension system
Inventor: SCHUESSLER ROBERT DIPL ING
IPC: B60G17/018
Filed: 1984-03-07
Abstract: On a vehicle (or a sprung body), sensors are arranged which generate signals x, which represent the distances of the individual wheels from the vehicle body. From these distances the computer calculates a "state vector", the components of which in particular represent an averaged height, an averaged pitch angle and an averaged roll angle of the vehicle body relative to the ground. The computer then determines an "adjusting force vector" F, the components of which in particular represent the forces and moments which must act on the vehicle body in a vertical direction or in respect of the longitudinal or transverse axis in order to adjust the mean height previously calculated and/or the calculated mean pitch and roll angle in a predeterminable way to the desired values. From the forces and moments calculated, support forces are then calculated, which have to be adjusted on the support units of the vehicle in order to produce the above-mentioned forces or moments in a vertical direction and/or in respect of the longitudinal and transverse axis. As a result of corresponding control of the support forces of the support units and as a result of the interference forces acting on the vehicle, the distances of the wheels from the body vary. The sensors in turn generate signals x corresponding to the distances, and the process described is repeated. <IMAGE>

Patent DE-3412560-A1 (DE)
Title: Rotary combustion engine
Inventor: WELZ RUDOLF
IPC: F01C1/073
Filed: 1984-04-04
Abstract: The advantages obtained by means of the invention stem in particular from the fact that due to the variable compression, a spontaneous ignition engine is produced with quantitative control which requires neither injection pump nor cold starting aid. The adjustable valve timings, the ever-present torque arm of constant length, the absence of valve control parts, the low internal friction resistance, the completely balanced distribution of masses result in a high thermal efficiency. In addition it is possible at any time to use unleaded fuels, even ones with low knock ratings.

Patent DE-3425426-A1 (DE)
Title: Ship-stabilising energy producer
Inventor: BARTRAM JUN JENS
IPC: B63B39/06
Filed: 1984-07-11
Abstract: Ship-stabilising energy producer or constructional arrangements for utilising energy and damping the rolling motion of a ship. This is achieved by the relative movement which a ship part oscillating with a degree of freedom performs relative to the hull being transmitted to a generator shaft or to the propeller shaft. The rolling motion is utilised in terms of energy and damped by a weight (in the form of a hold, a tank or other ballast) being able to oscillate about an axis situated amidships in the direction of the ship. The rotary movement of the axis is transmitted to a generator shaft. The pitching is utilised and dampened by a horizontal vane which can move up and down in front of the ship's bow experiencing buoyancy during pitching. The buoyancy leads to an upward or downward movement relative to the hull. A dividing plate of a liquid tank, which dividing plate is connected to the vane spindle, divides the tank into two chambers. By the movement of the vanes, the liquid is forced from one chamber into the other via a turbine. The turbine is coupled to a generator shaft. <IMAGE>

Title: Portable screwdriving tool
Inventor: HOLLAND-LETZ GUENTER
IPC: B25B17/00
Filed: 1984-07-11
Abstract: Portable screwdriving tool with a grip (25), designed for the simultaneous transmission of a torque and an axial force, in particular as a pistol grip, for a screwdriver blade (22) or the like. Via two ratchet locking mechanisms (1, 4, 42, 3) which are arranged in parallel and can be changed over to both directions of rotation via a common control sleeve (9), the grip (25) can be coupled to a continuous drive shaft (2) directly and via a transmitting planetary gear unit (7, 8, 61). The directly coupling locking mechanism (1, 4, 3) locks only in one direction of rotation in each operating position and can be overidden in the other direction when the planetary gear unit is effective in a transmitting manner. The drive shaft starting from the screwdriver blade is continuous up to the grip-side end of a cage (3) of the pawls (4, 42) of both locking mechanisms and is rotatably mounted and axially supported in this end. The grip-side end of the cage (3) sits in the grip (25) in such a way as to be locked against rotation. This portable screwdriving tool is distinguished by a compact construction and ease of motion as well as by the fact that it is easy to operate, for the axial force and the torque are introduced into the tool at the grip, the axial force being transmitted directly to the screwdriver blade so that special bearings absorbing the axial force are not necessary. <IMAGE>
