Title: Cooling-water container for the external watering of blast furnaces and the like
Inventor: JANHSEN JAKOBUS
IPC: C21B7/10
Filed: 1983-02-08
Abstract: The present invention relates to a cooling-water container for the external watering of blast furnaces and the like having an outer wall which is inclined to the furnace casing, and, provided with side walls, forms a container which is open on top and sealed off with respect to the furnace wall or is provided with outlet openings in its lower region. The cooling-water containers, which as a rule are arranged offset between the cooling boxes and distributed around the furnace casing, serve for the uniform distribution of the cooling water upon the external watering. The subject of the invention improves the distribution of the cooling water, malfunctions by clogging avoids and thus substantially prevents local overheating on the furnace casing. The optimal distribution of the cooling water is obtained by an outer wall of the cooling container which, curved in the direction of the cooling water flowing over it, is of convex design in order to utilize the adhesive forces of the cooling water with respect to the surface of the outer wall of the cooling-water container.

Title: Measuring arrangement for identifying the position of a point
IPC: G05G9/047
Filed: 1983-04-19
Abstract: A measuring arrangement for identifying the position of a point in a system having more than three degrees of freedom serves for the accurate determination and checking of the positional accuracy in conjunction with a unique reference point determination of manipulating equipment, e.g. industrial robots. In this case, the point to be identified is the origin of a spatial Cartesian co-ordinate system having mutually perpendicular co-ordinates which intersect in mutually perpendicular planes which are arranged at equal distances from the origin perpendicular to said co-ordinates. The measuring arrangement is designed such that the co-ordinates are formed by focused beams (2) from transmitting diodes (1) uniformly distributed on the circumference of a measuring cone (11), and the planes are formed by receiving diodes (3) opposite the transmitting diodes. It is preferred in this arrangement for three transmitting diodes (1) to be arranged at equal distances on the circumferential surface (11) of the cone with a conical angle of 90 DEG  on a plane (11a) parallel to the base surface of the cone. <IMAGE>

Patent DE-3315052-A1 (DE)
Title: Free piston engine
Inventor: WILHELM KURT
IPC: F02B75/02
Filed: 1983-04-26
Abstract: In the case of known free piston engines there is the basic problem that the power output is delivered only insufficiently or not at all. The actual combustion engine does not present any problems. The invention relates to a free piston engine in which, by quite simple means and without additional control, the power output is delivered in a manner suitable for free pistons, since it takes account of the physical factors of the free piston engine. In this free piston engine, the engine piston does not transmit its excess kinetic energy directly to the pump piston but only indirectly by way of the particular pressure in the two working chambers of the engine. The stroke of the pump piston is therefore a function of the frequency and pressure. The delivery quantity rises with increasing frequency and falls with increasing differential pressure. This double-acting free piston engine has only one engine piston and can be constructed in many different designs. It is particularly suitable for hydrostatic power output.

Title: Vessel and underwater vessel with separate propulsion
Inventor: MURGA JOSE
IPC: B63G8/00
Filed: 1983-07-26
Abstract: A vessel is disclosed which, to accommodate one or more persons, contains a cabin which can be sealed off water-tightly and is carried by at least one pair of a bar device which is connected to at least one pair of parallel floating bodies which keep the cabin at a distance with respect to the longitudinal axis. The floating bodies can be rotated about the axis of the cabin by means of the bar device, the same angle being constantly maintained on either side between the plane which connects the longitudinal axis of the floating bodies to the longitudinal axis of the cabin and the plane which passes through the transverse or lateral and longitudinal axis of the cabin. A mechanism for various stability states is thereby formed which permits a change in the speed and operation of the vessel when it is driven by any propulsion means by it being brought closer to the water surface or lifted from the water surface. The vessel can submerge completely by means of a mechanism which acts on the floating bodies.

Title: Fine frequency measuring method
Inventor: ARNOLDT MICHAEL DIPL ING
IPC: H04B17/18
Filed: 1983-10-18
Abstract: For remotely measuring radio transmitters, a receiver 4 in a manner known per se is supplied, in addition to the signal to be measured, with a high-accuracy first frequency fG generated locally and offset by a defined amount of, for example, 1 kHz, the resultant difference frequency of 1 kHz is filtered out and compared on the oscilloscope 6 with a reference frequency fv generated locally and corresponding to the difference frequency via a Lissajous figure 13. According to the invention, the reference frequency fv is extracted by frequency division 10 from a variable clock frequency fT which is, for example, 100-times higher and which, at the same time, is used for synchronous digital tuning of two identical switch filters with a resonant frequency which is in a locked relationship with the variable clock frequency. The first switch filter 5 filters out the difference frequency at the receiver output. The second switch filter 11 converts the subdivided clock frequency into a displayable sinusoidal voltage of the reference frequency. To increase the resolution, a frequency counter 14 indicates the clock frequency fT and thus n-times the difference frequency or reference frequency. A resolution of, for example, 1 kHz is thus sufficient for the frequency generator 2, instead of, for example, 1 Hz in the previously known beat measuring methods (Fig. 2). <IMAGE>
