The process of the invention makes it possible for the first time to use a conver-ter of economical design to supply a permanently excited single-phase al-ternating current machine, such as a transverse flux machine, and in so do-ing to turn all the advantages of this machine to account is a wide range of applications.
Patent CA-2109787-A1 (CA)
Title: Name translation in communications networks
Inventor: FRASER ALEXANDER G
IPC: H04M3/42
Filed: 1993-11-23
Abstract: Apparatus and methods used in a network for translating names into network addresses. Source nodes in the network receive names and have name caches for translating the names; destination nodes have have local name tables containing correspondences between names and the network addresses served by the destination node. There is further a name server accessible to the nodes which contains current correspondences between names and network addresses. A name is translated by first presenting it to the name cache in a source node; if there is no entry for the name in the cache, name cache maintenance code in the source node obtains information about the name from the name server; once there is an entry, the name is translated and a call set up message containing the name and the network address is sent to the destination node, which checks whether the name and network address are its local name table. If they are, the destination node returns a call complete message to the source node. Otherwise, it returns an unknown destination message to the source node. The name cache maintenance code responds to the unknown destination message by invalidating the cache entry and obtaining the correct information from the name server.

Title: Device for absorbing radiant heat energy
Inventor: SCHWARZ ALOIS
IPC: F24S10/75
Filed: 1994-03-04
Abstract: Abstract of the Disclosure:            A device for absorbing heat energy, in particular a solar panel, includes a housing in the form of a frame-shaped rack. The housing has a cover which allows the radiant energy to enter.          Several collector tubes are disposed below the cover and between a distributor tube and a gathering tube. The collector tubes are provided with wing-shaped collector elements. The collector tubes are rotatably mounted such that the collector elements can follow the position of the radiation source, such as the sun. The collector elements are thereby disposed at a mutual spacing such that a shading from the adjacent collector element is prevented, even at the lowermost position of the sun. The collector elements are further provided with a heat absorbing coating on both sides, and reflectors are provided below the collector elements as seen in the direction of the incoming heat radiation. Heat radiation which does not impinge on the top surfaces of the collector elements, and is thus not absorbed thereon, is reflected onto their bottom surfaces.

Title: Process for preparing fatty acid esters of short-chain monohydric alcohols
Inventor: WIMMER THEODOR
IPC: C11C3/04
Filed: 1992-11-03
Abstract: A process is disclosed for preparing fatty acid esters of short-chain monohydric aliphatic alcohols or monoalkylated diols by basically catalyzed esterification of natural, partially or totally synthetic fatty acid glycerides, as well as fatty acid glyceride-based waste products, such as used frying oils. The process is characterized in that the unpurified fatty acid glycerides, containing in particular high proportions of free fatty acids and phosphatides, (a) are esterified in one or several steps in the presence of a basic catalyst with an excess of short-chain alcohol or monoalkylated diol; (b) the glycerin phase produced after the first esterification step is at least partially added to the second or following step, after sterification has been carried out, and the mixture is stirred; (c) the glycerin phase is again separated, the supernatant fatty acid ester is cleared of excess alcohol or diol, then treated with a possibly diluted organic or anorganic acid, and if necessary filtered. This process, that is carried out without pressure and heat supply, is characterized by a technically simple implementation by means of simple equipment, and by a high degree of purity of the thus obtained fatty acid esters.

Title: Infinitely variable hydrostatic torque-routing transmission
Inventor: HAYD PETER
IPC: F16H47/04
Filed: 1994-12-16
Abstract: An infinitely variable hydrostatic torque-routing transmission with at least two operating ranges shiftable via switching elements includes a first, mechanical part, including a planetary differential gear, and a second, hydrostatic part, including two adjustable hydrounits. The hydrounits are coupled to each other energetically, are operable in both directions as pump or motor, and are coupled to the mechanical part.  The ring gear is coupled, in the various operating ranges, for control of the direction of rotation and speed of rotation of the transmission output shaft, to a first hydrounit, and with the second hydrounit being in the first operating range in drive connection with the transmission output shaft via an alternating switching element, while the first hydrounit, connected to the ring gear, operates as a pump and the second hydrounit as a motor.  The ring gear, by means of a second alternating switching element, can be selectively coupled by way of a first gear drive or a second gear drive to the input or output shaft of the first hydrounit.  The first gear drive is structured such that the ring gear and the input or output shaft of the first hydrounit rotate in different directions when the ring gear is coupled to the first hydrounit via the first gear drive.  The second gear drive is structured such that the ring gear and the input or output shaft of the hydrounit rotate equidirectionally when the ring gear is coupled to the first hydrounit via the second gear drive.

Title: Scsi disk drive power down apparatus
Inventor: BELMONT BRIAN V
IPC: G06F1/26
Filed: 1995-01-19
Abstract: An SCSI controller having a mechanism for receiving a power down request indicating that the SCSI disk drives should be spun down.  Preferably, the SCSI controller has an input for receiving a power down request signal.  The SCSI controller monitors activity on the SCSI bus and asserts a signal indicative thereof to power management logic.  The power management logic monitors the resources of the computer system and generates a system interrupt and the power down signal to initiate a power down mode when the computer system is determined to be idle.  The CPU receives the system interrupt to perform traditional power down sequences.  The SCSI controller receives the power down signal and generates a SCSI interrupt.  The CPU also receives the SCSI interrupt and executes an SCSI device driver.  The SCSI device driver determines that power down mode is being initiated, and sends spin down request commands to the SCSI controller for each SCSI drive.  The SCSI controller powers down each of the SCSI devices in response.  Any subsequent activity requiring access to any SCSI drive is detected by interrupt calls to the SCSI device driver, which then sends spin up requests to the SCSI controller, if necessary.
Patent CA-2141619-A1 (CA)
Title: Ultrasonic paging device for underwater divers
Inventor: HAYNES TOBY K
IPC: H04B11/00
Filed: 1995-02-01
Abstract: In devices used by underwater divers to summon other divers from a distance, an audible sound is transmitted through the water and must be heard by a diver's ear. In this invention, each diver carries an electronic device that transmits modulated ultrasonic acoustic waves through the water when he presses a pushbutton switch. This causes a similar device carried by another diver to emit an audible sound that the diver can easily hear. This device is effective over a greater distance because noise from breathing apparatus and the barrier of a diver's protective hood do not interfere with ultrasonic acoustic signals as they do with the detection of sound by a diver's ear. A number of different waveforms are used to modulate the acoustic carrier wave. These are used to convey information between divers, and to achieve separate operating channels so that independent groups of divers can use these devices in one area.
