Patent NO-179737-C (NO)
Inventor: TYLMANN JOSEF
IPC: C02F3/06
Filed: 1992-06-05
Abstract: The fixed bed reactor for biological waste water treatment is provided with an intermediate base (1) carrying base nozzles (2) by means of which the fixed bed can be backwashed. The inlet (3) for the waste water is located above the fixed bed. According to the invention, aeration nozzles (21) are integrated in the base nozzles (2) by means of which aeration nozzles gas bubbles (23) can be incorporated in the upper part of the base nozzles (2), without instabilities arising. In order that a stable equal distribution of the aeration occurs everywhere in the reactor, the open cross-section in the overall inlet region of each base nozzle (2) must be dimensioned so that above the aeration nozzles (21), the waste water outlet flow does not hinder the rise of the gas bubbles (23). If this condition is not fulfilled, the situation depicted in the picture (Figure 1a) can occur. <IMAGE>

Title: Mobile telephony system
Inventor: ISRAELSSON PER VIKTOR
IPC: H04B10/114
Filed: 1991-06-24
Granted: 2001-06-05
Abstract: A mobile telephony system intended for use by outdoor subscribers, for instance in cars, while affording, at the same time, high traffic capacity and relatively disturbance-free speech transmission to subscribers located within a building, for instance an office building. Signal transmission between mobile stations and base stations is effected with radio waves in a first sub-system for instance intended for telephony traffic via car telephones, and with light, at least in the area nearest the mobile stations, in a second sub-system intended, for instance, for an office building. Signal transmission with light can also be effected in areas that contain electronic apparatus which is sensitive to radio disturbances, for instance in hospitals and/or in areas in which strong radio disturbances capable of preventing mobile telephony transmission with radio waves occur. Certain mobile stations may be capable of being switched between signal transmission with radio waves and signal transmission with light, which enables these stations to be used in both subsystems.

Patent CA-2052968-C (CA)
Inventor: CHAN MICHAEL Y
IPC: B65D83/08
Filed: 1991-10-08
Granted: 2002-02-12
Abstract: Disclosed is an interleaved L-fold towel arrangement which minimizes a number of different types of commonly occurring paper towel dispensing failures. Each towel in the interleaved stack of towels in the present invention is comprised of a sheet which has been folded in half to substantially create a two-ply arrangement. A second fold is imparted to the towel substantially to the first fold thereby creating a lead flap and a trailing flap. The lead flap begins with the first fold and thereby creates a tab end which is two-ply and which will not delaminate on dispensing. The user will thus always be grasping a two-ply product as it is being dispensed thereby minimizing tear-out and tab-out failure.      The lead flap preferably has less width than the trailing flap, thus limiting the amount of deformation which must be imparted by the trailing flap to the lead flap next to be dispensed to cause said lead flap to be drawn through the dispensing opening of a dispenser.

Abstract: ABSTRACT OF THE INVENTION    A fluid pump for infusing medical fluids to a patient includes a housing having an inlet port and an outlet port.          The housing further includes a substantially hemispherically shaped surface which is circumscribed by a periphery.   An elastomeric membrane is attached to the periphery of the surface and  is  stretched over the  surface  to place the membrane in its region of nonlinear elasticity.  With this combination, a potential fluid chamber is established between the surface of the housing and the stretched membrane.    In operation, fluid is injected through the inlet port and into the potential chamber between the housing and the elastomeric membrane to fill the chamber with the desired medical fluid.  A fluid line is connected to the outlet port of the pump and a flow restrictor is coupled with the fluid line to control the flow of fluid from the chamber.  Fluid flows  from  the  chamber  as  a  result  of  the  nonlinear contraction of the elastomeric membrane. 10700.167                      -35-

Title: Fluid drill-hole treatment agents based on polycarboxylic acid diesters
Inventor: MUELLER HEINZ
IPC: C09K8/26
Filed: 1991-06-07
Granted: 2003-12-30
Abstract: Described is the use of oleophilic esters of ecologically compatible polycarboxylic acids with oil-soluble and ecologically compatible monofunctional alcohols and/or polyfunctional alcohols which may also be watersoluble as the oil phase or as a component of the oil phase of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The oleophilic polycarboxylic acid esters are especially suitable as component of the continuous oil phase of inverted fluids of the W/O type. Here - if rheologic-ally suitable compounds will be employed - they may comprise the at least predominant portion of the con-tinuous oil phase; but also possible is the concomitant use of complex oleophilic polycarboxylic acid esters, which are not or just to a restricted degree fluid in a temperature range of from 0 °C to 20 °C, as an additive in fluid oils of the class of the non-polluting oils.      Here, suitable oil mixing phases especially are oleo-philic alcohols, ethers, respective esters of mono-carboxylic acids and fluid oils based an oleophilic carbonic acid diesters.

Title: Mixed mode stepper motor controller and method
Inventor: EYERLY BRUCE N
IPC: H02P8/24
Filed: 1993-04-23
Granted: 1997-11-25
Abstract: A mixed mode controller (100) for use with a motor having a mechanism (110, 114) for generating a command signal to operate the motor and a first circuit (104) for adjusting the gain of the command signal to provide high speed operation.  A second circuit (102) is provided for converting the command signal to a drive signal to excite a winding (106) and to damp the motor.  In a preferred embodiment, a step rate signal introduced into the motor controller (100) is operated upon by  an accumulator (110) and a memory (114) to generate a voltage command signal.  The motor controller (100) includes a low bandwidth current control feedback loop (104) utilized to adjust the gain of the voltage command signal by comparing a command motor current and an actual motor current in a summer circuit (126).  The feedback loop (104) provides for automatic gain control of the voltage command signal for yielding  high speed operation.  The gain-adjusted voltage command signal is thereafter applied to a bipolar voltage driver (102) having high motor damping characteristics.  The voltage driver (102) is utilized to control the application of a bus voltage to the motor winding (106) of a stepper motor via a transistor control logic circuit (148).  Also included is a time constant correction network (138) for accelerating the settling of variations in the motor current to steady state.   Thus, the correction network (138) ensures a rapid response to changes in the commanded motor current.

The rotation preventing/thrust bearing device includes a discrete fixed portion, a discrete orbital portion, and bearing elements. The fixed portion includes a first annular race and a first ring, both of which are formed separately. The first annular race is placed in a loose fit surrounding a first annular step in an inner surface of the housing and the first ring is attached to the housing. The orbital portion includes a second annular race and a second ring, both of which are formed separately. The second annular race is placed in a loose fit surrounding a second annular step in an end plate of the orbiting member and the second ring is attached to the end plate of the orbiting member. A plurality of pockets of the rings face one another in generally aligned pairs. A bearing element is received in each aligned pair of pockets to prevent the rotation of the orbiting member by the bearing elements interacting with the first and second rings and to carry the axial thrust load from the orbiting member. The first and second annular anti-weal plates are overlaid surrounding the first and second annular races, respectively. The first and second annular anti-wear plates are fixedly placed within the first and second annular steps respectively in order to prevent the circumferential and radial movement thereof.
