Abstract: An improved apparatus for introducing steam into an airstream in a heating, ventilating and air conditioning system includes a supply header, steam dispersing structure and structure for collecting condensation from the steam dispersing structure.  The supply header is adapted for connection to a source of steam and is preferably elevated with respect to the return header, so that condensation in the supply header is forced into the return header under the influence of steam pressure and gravity.  Both headers may further be inclined to improve drainage of condensation.  The invention optionally may utilize fenders in conjunction with the steam dispersing structure to minimize heat transfer to the airstream.

Title: Parallel processor memory system
Inventor: KIM WON S
IPC: G06F15/80
Filed: 1991-01-04
Abstract: A massively parallel processor includes a plurality of clusters (40). Each cluster includes processor elements (50.00-50.15) ("PEs") and a cluster memory (54). Each PE (200) has an address register (206), stage register (251), error register (310), enable flag (336) memory flag (338), and grant request flag (211). A cluster data bus (225) and error bus (302, 304) connects each stage register and error register of the cluster to memory (260). The grant request flags of the cluster are interconnected by a polling network (362, 364), which polls one grant request flag at a time. In response to a signal on polling network (362, 364) and the state of the memory flag (338), grant request flag (211) determines an I/O operation between data register (251) and cluster memory (260) over cluster data bus (255). Data and error bits are associated with respective processor elements (200). Sequential memory operations (110 - 113) proceed in parallel with parallel processor operations (102 - 109) and may be queued. In direct address mode, a PE (200) addresses its own address space by appending its PE  number (203) to a broadcast partial address furnished over a broadcast bus (250). The PE number (203) is furnished on a cluster address bus (246). In indirect address mode, PE addresses its own address space or that of other PEs in its cluster by locally calculating a partial address, then appending to it its own PE number (203) or that of another PE in its cluster. The full address is furnished over the cluster address bus (246).

Title: Apparatus for measuring physical properties of fluids_
Inventor: FAVRE PIERRE
IPC: G01F1/696
Filed: 1991-11-05
Abstract: The apparatus is comprised of two sensors of the thermal type (11a, 11b) made of materials resisting without any alteration to a temperature of 650  DEG C. Probes (15a, 15b) are controlled by a microprocessor (16) to come periodically and momentarily in contact with said sensors in order to calculate (through microprocessor (16)) the thermal time constant of said sensors presenting a deposition layer of environmental pollutants. The microprocessor (16) compares the value of said time constant with an order value that commands the closure of a shunt switch (17) of a resistance (18) which, when short-circuited, determines a reinforced heating of the sensors to bring them to a temperature of incineration of organic materials originating from the pollution of the ambient medium and deposited on said sensors. Thus, the sensors are maintained in the cleanliness conditions of their surface, thereby providing for the accuracy of information supplied by said sensors outside cleaning periods.

The tines are curved such that the outer end of the tine, being rounded in shape, is directed towards the trailing end of the harrow when in operation.  The tines, and to a lesser extent, the mounting plates, are resilient in nature and adapted to be deflected towards the trailing end of the harrow, when obstacles such as rocks are encountered.  The tines are also capable of some pivotal deflection, to a lesser extent.

Inventor: TSAGAS NICOLAOS
IPC: B60C23/02
Filed: 1992-02-06
Abstract: A device for monitoring tyre pressure whilst the vehicle is moving can operate with the help of: two complete circular metallic strips (56, 57) placed on an insulated surface of the internal side of a brake drum (25) or on an insulated surface of the disk brake; two metallic strips (58, 59) placed on a non-rotating part of the vehicle forming two complete circular strips (58, 59); a pressure gauge sensor (1) and electronic signal generating circuitry (19, 40, 41). The non-rotating strips (58, 59) are placed parallel to the rotating strips (56, 57) and very close to them so as to form a pair of air capacitors (56, 58) (57, 59). The electronic circuit (19, 40, 41) produces high frequency alternating voltages which are applied to the plates of the capacitors (56, 58) (57, 59). In case of dangerous tyre pressure the sensor (1) closes the circuit, an alternating current flows and a warning device is activated. The current thus flowing in the capacitor circuit does not pass through the wheel bearing (34).
