Filed: 1993-02-13
Abstract: The fuel delivery unit comprises a multistage delivery pump containing a delivery pump first stage (38), downstream of which, in the delivery direction, a further delivery pump stage is arranged. The delivery pump first stage (38) has a rotor (impeller) (24) which is driven in a rotary manner and in whose outer perimeter two recesses (52) are formed, which serve as delivery elements, are open in the direction of rotation (53) of the rotor (24), and by means of which fuel is delivered owing to the dynamic pressure produced therein. The rotor (24) axially adjoins a casing wall (58) and is surrounded, at its circumference, by a cylindrical casing section (60), in which, distributed over its circumference, a multiplicity of orifices (61) are present via which the rotor (24) communicates with the storage tank. Fashioned within the casing wall (58) there is an annular delivery duct (62) which is covered by the end face of the rotor (24) and with which the recesses (52) communicate via orifices (65) in the rotor (24). The delivery duct (62) is connected to the suction side (intake side) of the downstream delivery pump stage. <IMAGE>

Title: Multifilament bulky yarn prodn. - utilising sideways motion in the cooling rail to evenly spread the surface oil
Inventor: INUYAMA HISAO
IPC: D02J1/22
Filed: 1993-03-22
Abstract: A process to produce texturised and orientated bulky yarn, with a false twist is in stages, with thermal fixation of drawn and twisted yarn, followed by contact with a cooling surface, and then twisted back. The yarn is constantly moved with a side-ways motion when in contact with the cooling surface. The appts. is also claimed. Pref. the partly orientated multifilament yarn is drawn and orientated with thermal fixation and then cooled before being twisted. The process may be repeated, removing the twist to produce an even quality of yarn. The cooling is by being drawn along a V-section stainless steel rail (9), which has a small amt. of curvature from one end to the other. As the yarn (Y) travels along at the top of the V curve (20), it is compelled to move sideways in the direction (a) or (b) and back. A deposit of oil (c) may require an increase in the movement. This movement may be achieve by having a series of slots in the rail, with hangers passing through the slots to guide the yarn. A crank is coupled to the hangers, and a drive gives the sideways motion required. This movement ensures the smear of oil is adequately spread during the cooling stage. The sideways motion may be provided by several airjets placed along the cooling rail, to blow upwards into the V. ADVANTAGE - The process eliminates the shading effect which can arise when dyed texturised bulky yarn is woven into cloth.

Title: Method and arrangement for automatic transmission of information via a telephone network
Inventor: KARSTAEDT JOERG DIPL ING
IPC: H04M1/658
Filed: 1993-07-21
Abstract: According the object of the invention, detailed information relating to a specific event is intended to be transmitted from an unmanned transmitting station to a receiver when this specific event occurs. The solution which achieves this object is used in particular in alarm systems. In known alarm systems, neutral information is normally transmitted and the transmitting station and the station receiving the information must agree between themselves on the responses which should be triggered by an alarm signal. According to the invention, information which was previously stored in a memory and which provides further details in the national language on the location and type of the event is transmitted via a connection-line-independent telephone after an event detected by a sensor. A previously made agreement on responses is therefore not required. <IMAGE>

Title: Process for producing hollow mouldings from thermoplastic material by injection moulding and a mould for carrying out the process
Inventor: SCHESCHARK FRANZ
IPC: B29C45/17
Filed: 1993-10-01
Abstract: For producing hollow mouldings from thermoplastic material by injection moulding, polymer melt is introduced into the cavity (22) of a mould (20) via a runner (24) and subsequently the polymer is forced out of the region forming the hollow space in the moulding into the open by gas introduced into the polymer under pressure. For this purpose, at the same time as the gas is introduced, a closable and heatable outlet channel (28), leading out into the open, is opened and the polymer forced out by the gas is expelled out of the cavity (22) through this outlet channel (28), whereupon the outlet channel (28) is closed again before the gas can flow out. <IMAGE>

Title: Electron cyclotron resonance device
Inventor: SUNG ROH YOUNG
IPC: H01L21/00
Filed: 1994-02-04
Abstract: An electron cyclotron resonance device serves to treat a wafer with plasma which is produced by using an electron resonance. The device is designed in such a manner that a uniform temperature curve of a wafer is improved by injecting helium as a heat-transferring medium between the wafer and a wafer support, on which the wafer rests. Heat is thereby transferred from the wafer to the wafer support. Furthermore, the device is designed in such a manner that it moves wafers into a desired treatment position. The result thereof is that semiconductor devices can be produced which have better performance.

Title: Device for ascertaining an alcohol concentration in a fluid
Inventor: OGAWA KENJI
IPC: G01N33/28
Filed: 1994-03-15
Abstract: A device for ascertaining an alcohol concentration in a fuel-alcohol mixture which contains an arbitrary alcohol addition to petrol or light oil, has a detection device for ascertaining the dielectric constant, which device outputs a resonant frequency corresponding to the dielectric constant of the fuel-alcohol mixture whose alcohol concentration is to be established. A resonant-frequency detection device discerns the said resonant frequency and outputs a first frequency-output signal at the same frequency as the resonant frequency. A frequency divider divides the first frequency-output signal by a variable frequency divisor. A fuel-temperature detection device ascertains the temperature of the fuel-alcohol mixture and outputs a second frequency-output signal which corresponds to the ascertained temperature. A divisor-decision device determines the frequency divisor with the aid of the first and second frequency-output signals of the resonant-frequency detection device and the temperature-detection device. The alcohol concentration is thus determined with the aid of the output frequency of the frequency divider.
