Title: Method and device for controlling the oil flow rate through an atomiser nozzle of an oil burner
Inventor: JOVY HERBERT DR
IPC: F23D11/26
Filed: 1982-04-16
Abstract: A description is given of a method and a device for carrying out the method for the continuously variable control of the oil flow rate through an atomiser nozzle of an oil burner, the oil flow fed to the atomiser nozzle being passed through a passage valve controlled by the temperature of the oil. The passage valve consists of a valve sleeve (7) with a valve seat (9) and of a valve tappet (10), inserted with play in the sleeve and having a valve head (11). The material of the valve tappet (10) has a higher coefficient of expansion than the material of the valve sleeve (7) with the result that, when the temperature rises, the valve tappet (10) expands more than the valve sleeve (7). Due to this expansion of the valve tappet (10), the valve head (11) rises from the valve seat (9). The size of the passage freed in the process depends on the degree of heating. <IMAGE>

Patent DE-3225019-A1 (DE)
Title: Tool with shrinkage slot
IPC: B23D61/12
Filed: 1982-07-05
Abstract: The heat developing in the areas A x F can only lead to shrinkage in this region, since, given correct dimensioning, on the one hand the heat supplied remains restricted to this surface region and on the other hand the shrinkage cannot be transferred by the reduced web width into the supporting body if this shrinkage is sufficiently small compared with A. In addition, the ratio of the lengths E to B must be large enough to obtain the shrinkage-limiting effect. The ratio A to F must be sufficiently small, where for design reasons F must not be selected to be too large. To obtain as large a connecting area (3) as possible, the slot width S should be as small as possible.

Title: Hand shower as sanitary fitting
Inventor: TENGE-RIETBERG CARL FRIEDRICH
IPC: B05B1/16
Filed: 1983-01-08
Abstract: In a hand shower as a sanitary fitting, the shower housing (10) formed on a handle (11) with an inflow channel (12) is equipped with a hemispherical pressure chamber (14) which sets in circulating motion the water flowing in under pressure (inflow nozzle 13) with inclusion of an air core (17). The few holes (16) of a perforated shut-off plate (15) bounding the pressure chamber (14) are scavenged with water until the compressed air core (17) expands and thereby pushes the water out of the holes (16) in a jerky manner. Such a process is constantly repeated, so that the water from the passage holes (23) exits pulsatingly. Moreover, the shower head (20) can be constructed so as to be capable of rotation around a central pin (18), thus forming detent connection, the pulsating water being conducted round via the bores (28) to the shower openings (27) of the shower head (20). <IMAGE>

Title: Production and process for maintaining or preserving fresh meat aroma in freshly slaughtered pigs and production of meat and sausages from this freshly slaughtered pig meat
Inventor: ZWIENER FRANZ
IPC: A23L13/00
Filed: 1983-05-31
Abstract: By closing the pores of freshly slaughtered pigs, the good characteristic aroma is maintained in the meat. Just two possible ways exist for closing the pores, depending on the choice of treatment and processing. Firstly by heat at approximately 75 DEG C. Secondly through the use of autogenous protein. In both cases, the aroma is maintained in the product. Even subsequent deep freezing does not harm the aroma.
Patent DE-3322712-A1 (DE)
Title: Optical distance-measuring method
Inventor: SCHUESSLER HANS H DR ING
IPC: G01B11/02
Filed: 1983-06-24
Abstract: The invention relates to an optical distance-measuring method for touching the surface of an object to be measured by means of a primary light bundle emitted in the direction towards the surface of the object and focused in the region of the surface at a focal point. The focal point is set into periodic oscillations of a defined fundamental frequency and amplitude about a central position which can be varied in distance from the surface, and the intensity of the secondary light retroreflected from the surface is measured. At least one harmonic, namely the octave component of the fundamental frequency, is isolated from the intensity signal for the secondary light, and a search is made for the amplitude maximum which occurs when the central position of the focal point is displaced precisely into the surface. It is possible to increase the measurement accuracy or the resolution substantially by evaluating the octave component of the intensity signal, since the passage of the central position of the focal point through the surface is expressed as a sharply delimited amplitude peak in the octave component of the intensity signal. By contrast, in the passage of the focal point through the surface, the original intensity signal has a flat maximum, which can be determined using measurement methods customary to date but can be localised only with difficulty.

Title: Method for regulating a stepping switch mechanism
Inventor: HANSEN HERBERT
IPC: G05B19/07
Filed: 1983-08-23
Abstract: A method is described for regulating a stepping switch mechanism in which a time sequencing circuit (14) is moved on by a plurality of steps as a function of an actual value (1), and time generators (7, 8, 9) are started in the event of a regulation deviation. In order to conform to the regulation requirements, it is proposed that the time generators be started when voltage is applied to the stepping switch mechanism and, once the times which are predetermined on the time generators have elapsed, these times be stored, that switching takes place without delay via a time generator in the event of a regulation deviation, and the corresponding time generator is started again. <IMAGE>

Title: Use of a hot-formable hardenable nickel alloy for hot wear-resistant hot-working tools
Inventor: FRICKE WERNER DIPL ING
IPC: C22C19/05
Filed: 1983-09-19
Abstract: The invention relates to the use of a hot-formable hardenable nickel alloy for hot-working tools, which can be highly stressed in the temperature range from 650 to 850 DEG C, in the metallurgical and metal-working industries. By comparison with the known technological solutions, it is the object of the invention to obtain an improved hot wear-resistance of the hot-formable hardenable nickel alloys for hot-working tools and at the same time to obtain improved toughness and temperature shock resistance as compared with cast CoCrW or surface-welding alloys (stellites). According to the invention, this was achieved when, to ensure hot-formability, a nickel alloy fixed in composition and containing > 15% by weight of W and Mo is alloyed with 0.05 to 0.50% by weight of rhenium. A hardness > 450 HV after hardening is guaranteed. The use of the alloy according to the invention also ensures smelting with other iron alloys as the hot-formable composite, and surface diffusion treatments for further increasing the hot wear behaviour can also be carried out. Characteristic applications are forging saddles, hot-shearing blades and hot-working tools for extruders.

Title: Swimming pool cover
Inventor: KOEHNE VOLKER
IPC: E04H4/06
Filed: 1983-11-24
Abstract: There are swimming pool covers which comprise hollow profiles to which a reversible air pump is connected in such a way that, when air is extracted from the hollow profiles through openings, water enters them and the hollow profiles sink to the bottom of the pool and, when air is pumped in, the water is displaced, the hollow profiles rise to the surface of the water and cover the swimming pool. Difficulties arise in as much as during floating-up and sinking-down, the cover assumes an inclined position since, for one thing, the air is not fed in uniformly and the entire amount of water of the swimming pool has in each case to flow to the other side of the cover. In order to achieve a controlled lowering and re-floating of the swimming pool cover in a horizontal position with little time involved, it is proposed to fit the hollow profiles to air lines, a small number of the hollow profiles at a distance from one another being closed on all sides and swivel-mounted, and that the remaining hollow profiles are connected via air connections to the air lines.
