Abstract: To measure the heat transfer coefficient of a sample, an element with temperature sensitive optical properties is placed in contact or implanted in the sample. The element is heated or cooled. The temperature difference between the element and the unheated sample and the rate of heating or cooling indicate the heat transfer coefficient of the sample. In one embodiment, the element is heated or cooled at a constant rate. The heat transfer coefficient of the sample is then inversely related to the difference in temperature between the element and the unheated sample. Alternatively, the element may be heated or cooled at such a rate that the temperature difference between the element and the unheated sample remains substantially constant. The heat transfer coefficient of the sample then varies directly with the rate of heating or cooling. The heat transfer coefficient of a sample is a measure of its composition and other physical properties. The composition of gasses, liquids, the presence of bubbles in a liquid, and fluid levels can be detected by the optical technique. Pressure and flow rates of fluids can also be detected. The technique can be used also to more accurately measure the thermal conductivity and temperature of small objects with small heat capacities.

Abstract: The main memory of a data processing system comprises a plurality of modules, each with four memory planes (60), each storing 16k 39-bit words (32 bits data plus 7 parity bits). Write data is received from a controller on a write data bus (WDO-38) and read data goes to the controller on a read data bus (RDO-38). Up to 16 modules can be selected by fourselecting bits (MOD SELO-3) which are compared by a comparator (66) with the module's own address (MODO-3). 
     The memory planes are accessed in sequence using seven address bits (ADDRO-5, J ADR 6) latched in address latches (67) in conjunction with a row address strobe (RAS) and a column address strobe (CAS) which strobe in row and column addresses sequentially from the latches to complete the selection of a single word to be written or read. Control logic (65) controls selection of write and read operations in response to signals (LDIN, LDOUT), and refreshing in response to a refresh signal (REFRESH).

Abstract: © A leak-proof insert for sealing in a fluid passageway and which may be a plug for the passageway but in a preferred embodiment forms part of a nozzle assembly comprising a tubular sleeve (20), a nozzle (18) and a nozzle body (16). The nozzle and nozzle body are held in an assembled relation with their bores (40, 34) aligned by the tubular sleeve which encircles them. The sleeve provides a seal between the nozzle assembly and housing (10) into which the nozzle assembly is mounted, and also provides a seal between the nozzle and nozzle body. During use, when under working pressure, the tubular sleeve tends to flow and move both downstream and radially, forming seals between the nozzle assembly and housing; and between the nozzle and nozzle body, which seals tend to increase in effectiveness as the working pressure increases. The nozzle body described is a set screw enabling insertion in the housing and may have a chamfer (50) which engages a corresponding circular corner (52) of the housing, preventing downstream flow of the sleeve therebetween.

Abstract: Erfindungsgemäß erhält man aus einer wäßrigen Suspension eines Azodispersionsfarbstoffes durch Zusatz eines Tensids oder mehrerer Tenside, die einen Trübungspunkt in wäßriger Lösung haben, nach der Isolierung des Farbstoffes bei einer Temperatur oberhalb des Trübungspunktes wäßrige Preßkuchen mit einem hohen Gehalt an diesem Farbstoff. Die direkte Verarbeitung von Preßkuchen, wie sie beispielsweise nach der Synthese und Isolierung von Azodispersionsfarbstoffen anfallen, zu für den Anwender praxisgerechten Dispersionen erfordert einen Mindestgehalt an Farbstoff in den Preßkuchen. Der Mindestgehalt wird bei Anwendung der herkömmlichen Isolierverfahren in vielen Fällen nicht erreicht, so daß der Umweg über eine Trocknung zu Pulver und Redispergierung der Pulver notwendig ist. Der kostenintensive Umweg kann bei Anwendung des erfindungsgemäßen Verfahrens eingespart oder gegebenenfalls die Trocknung zum Pulver erheblich verbilligt werden.

Abstract: A gastrointestinal sphincter to be surgically implanted around a lumen (e.g. bowel) of a patient to apply variable occlusive pressures for articulating the lumen. The sphincter includes a continence producing occlusion cuff (1) having a hollow, expansible chamber (2) formed therein to embrace the lumen. Communicating in a single, continuous fluid circuit with the expansible chamber are first (6) and second (32) fluid circuits having respective first and second reservoir supplies of fluid (30 and 46) located therein. Each of the reservoir supplies may be selectively actuated in order that fluid will be delivered to the expansible chamber to controllably expand the chamber and thereby produce variable occlusive pressure levels for achieving continence. A fluid filled physician control port (24) is interconnected with one of the fluid circuits (6) and surgically implanted so as to be accessible to a fluid filled syringe. A carefully controlled volume of fluid from the port can be delivered to the expansible chamber via the associated fluid path to generate the minimum increased occlusive pressure necessary to achieve coaptive continence according to the tissue requirements of the patient.The occlusion cuff also has a relatively extensible membrane (56) that is subject to variable elongation in response to at least a predetermined minimum tensile stretching force. The membrane is interconnected with the occlusion cuff to increase the circumference of the cuff around the patient's lumen to thereby accommodate possible distention of the lumen.

Abstract: The body (1) of a vehicle has a floor and two sides, with a body longitudinal center line (L1) being defined midway between these two sides. A driver's seat (4) is fixed to the floor on one side of this body longitudinal center line, and a front passenger's seat (5) is fixed to the floor on the other side thereof. The approximate center (L3) of the driver's seat (4) lies substantially closer to this body longitudinal center line (L1) than does the approximate center (L4) of the front passenger's seat (5). Thereby, more room is obtained for the driver, at the expense of somewhat diminishing the room available forthe front passenger. Further, it becomes possible for the driver's seat (4) directly to oppose the control pedals (6, 7, 8), without any slanting sitting attitude being required from the driver. Optionally, a hand brake lever (10) and/or a transmission shift lever (9) may be fitted approximate'y on the central line between the driver's seat and the front pa ,senger seat, and further optionally the central point between the inner ends of the sun visors (12, 13) for the driver and the front passenger may also lie approximately on the seat center line, at which seat center line further, optionally, the rear view mirror (11) may be positioned. Thereby, the essential asymmetry of this passenger compartment arrangement may be effectively concealed from the beholder.
