Title: Transfer arrangement consisting of a pump with a driving device
Inventor: KARGE VOLKMAR DIPL ING
IPC: F04C27/00
Filed: 1988-05-24
Abstract: The invention relates to a transfer arrangement comprising a pump with a drive appliance, in particular an electric motor, the pump being enclosed on all sides by a pump housing, which has an inlet chamber with an intake aperture and a pressure chamber with an outlet aperture. In order to be able to use this transfer arrangement under water, in particular even at great depths, the following characteristics are proposed: a) the watertight pump housing is connected to a similarly watertight motor housing accommodating the drive appliance, which housing encloses a motor compartment surrounding the encapsulated drive unit, the motor compartment being divided off liquid-tight from the said inlet chamber by a first partition wall area; b) arranged in the first partition wall area are the motor-side bearing of the pump shaft and/or spindle and their seals for sealing off the motor compartment from the inlet chamber, these seals being connected on the pump side to the said inlet chamber and hence exposed to the conveying medium; c) the said motor compartment is filled with oil which serves for lubrication of the bearing, any gears etc., comes in contact with the seals and dissipates the heat via the said motor housing to its surroundings; d) the said inlet chamber is connected to a pressure equalising chamber, with which it exchanges liquid, which has at least one wall deformable into the oil-filled motor compartment in the event of increasing pressure admission.

Abstract: A method of treating fluids to induce coagulation of particles comprises subjecting the fluid to the influ­ence of a repulsive magnetic field, that is a magnetic field generated between opposed like magnetic poles as distinct from a magnetic field generated between North and South poles. Preferably oligo-dynamic particles of mineral or other substances are introduced into the fluid before, during or after magnetic treatment. The prefer­red method or particle introduction is by sacrificial anode incorporated in an electrical circuit with a cathode and the fluid as an electrolyte. The invention may be applied to the treatment of hard water to prevent or reduce deposition of scale and in the treatment of swimming pool water to eliminate bacteria and/or control formation of algae. A variety of other uses in relation to both liquids and gases are described.

Abstract: This invention is directed to the preparation of glass-­ceramic materials especially suitable for use in multilayer substrates for integrated circuit packages. The inventive glass-ceramics are derived from thermally crystallizable glasses which, in the form of frit, are capable of being sintered into an integral body at temperatures below 1000°C and essentially concurrently crystallized  in situ  to yield BPO₄ as the predominant crystal phase. The inventive glass-­ceramics exhibit a linear coefficient of thermal expansion between about 30-45 x 10⁻⁷/°C, a dielectric constant less than 5, and consist essentially, in weight percent, of 10-25% B₂O₃, 20-40% P₂O₅, and >50-65% SiO₂.

Abstract: Le procédé, et le dispositif correspondant, de détection des variations de temps de propagation dans l'anneau d'une interféromètre utilise une modulation de phase des ondes contra-rotatives parcourant l'anneau par des créneaux asymétriques à une période double d'un temps de propagation initial, qui créent des paliers à décalage de phase nul dans la modulation de la différence des deux ondes émergent de l'anneau. Ces paliers se traduisent par des impulsions dans le signal détecté de sortie dont la largeur est variable avec le temps de propagation.L'invention s'applique, notamment au contrôle de la longueur d'onde de la source de l'interféromètre, particulièrement du fait des variations de température de la source.

Abstract: A single chip cache memory device can operate alone, and can operate together with like cache memory devices so that the overall cache memory capacity can be expanded by the number of devices connected in parallel, with each single chip cache memory device being self-constructed so as to contain circuitry to facilitate their parallel connection. When a plurality of single chip cache memory devices are connected in parallel to constitute a large memory capacity cache memory apparatus, the access to the main memory on a cache miss-hit is permitted only for the cache memory device having a code that coincides with the code portion of the address signal, and access to the main memory for the remainder for the cache memory devices during the miss-hit is inhibited. This is accomplished by providing a specific different code to each one of the cache memory devices connected in parallel.

Abstract: The invention is based on a specific winding former for coils which can be drawn into the stator of an electrical machine. The said former consists of two former halves which can be plugged at an adjustable spacing onto circumferential supporting bars. One of the former halves has, on the base side, a detachable coil support with a retaining opening for a third supporting bar. To avoid repeatedly having to produce new winding formers for different winding types and stator dimensions, a structural element system is proposed in order to be able to produce formers of any desired shapes and sizes from a comprehensible number of different elements. A former half accordingly consists of a central piece (5) which can be plugged onto the relevant supporting bar and individual former elements (10), each having a wire chamber which can be plugged onto the central piece (5), it being possible to select the radial spacing between individual former elements with the aid of spacers (17) which can be inserted between them. Magnetic means of adhesion between the central piece (5) and a coil support, and the division of the latter into a plurality of supporting chamber fixtures, permit a relatively wide variation and simplify working with such winding formers. …<IMAGE>…

Title: Method to signal the free and occupied state of track sections in railway shunt arrangements, and device to perform this method
Inventor: JUNG MARTIN ING GRAD
IPC: B61L17/00
Filed: 1989-04-24
Abstract: During shunting, it occasionally occurs that a points-circuit zone is prematurely reported as free below an unusually long vehicle by the associated track free report device. Special measures then have to be taken in order to prevent the points turning below this unusually long vehicle. For this purpose, the invention provides for the free report signal of the track free report device (GFAW) only to be evaluated as a free report of the associated track section if it has been ensured that all the axles of a vehicle (FZ) or a group of vehicles travelling over the section have previously travelled into the section. For the first section in the driving direction of a track system, this is determined by an indicator (EL) which detects the completion of the passing of the vehicle or of the group of vehicles. The indicator signal (EFWA) which occurs earlier in time is connected to the free report signal (GFWA &uarr& ) of the track free report device to form a vehicle end code (FEZA) which indicates that the vehicle or the group of vehicles has left the first track section. This vehicle end code (FEZA) is connected, as the vehicle or group of vehicles advances further, to the free report signal (GFZA &uarr& ) of the track free report device of the following track section to form a new vehicle end code (FEWB) for this section which indicates that the second section is completely cleared. This process continues as the vehicle or group of vehicles advances from section to section. <IMAGE>

Abstract: A process for producing coke from a combined feed. The combined feed is initially provided as a first portion (16) which comprises easily cokable components and a second portion (25) which is essentially free of easily cokable components. The first portion is heated (18,19) to a temperature lower than that normally employed by a coking heater in a delayed coking process. The second portion is heated (20,21) to a temperature at which a combination of the first and second portion provides combined feed at coking temperatures. The combined feed is then subjected to coking conditions (24). 
     The first portion, in one embodiment, may be comprised of a fresh feed (10˝) and the second portion may be comprised of a coker recycle (46). In another alternative, a fresh feed (10′) and a coker recycle (38) are combined and fractionated to produce the first portion (30) and the second portion (32). The first portion may include components which boil above a temperature of about 900°F, and the second portion may be essentially free of easily cokable components.
