Filed: 1992-02-14
Abstract: In a process for industrial fractionation of polymers using an extraction column and a homogeneous extraction agent a homogeneous feed is supplied to a region of the extraction column which is nearer the upper end thereof when the feed has a greater density than the extraction agent and which is nearer the lower end thereof when the feed has a lower density than the extraction agent. An apparatus for carrying out this process consists advantageously, instead of a pulsed sieve plate column as hitherto, of an unpulsed filling body column which leads to a better separation because a back mixing is avoided in favourable manner.

Title: Dentifrice compositions
Inventor: ALEXANDER STEPHEN E
IPC: A61P1/02
Filed: 1989-10-11
Granted: 1997-09-16
Abstract: The problem of formulating a dentifrice which is compatible with a bis-biguanide anti-bacterial agent, for instance chlorhexidine or alexidine, is solved by using a nonionic thickening agent; a nonionic surfactant; and an abrasive which is either a sparingly soluble salt, for instance calcium carbonate, (used in combination with an agent to suppress anion formation), or an essentially insoluble compound, for instance, a silica of low anion content, or a mixture thereof. Preferably, the composition has a flavour which is mainly aniseed, balanced by mints.  Preferably during the preparation of a silica containing dentifrice, chlorhexidine and saccharin are added together at an early stage, prior to the addition of silica, to avoid the formation of lumps.  Such dentifrices are useful in the prophylaxis and/or treatment of periodontal disease and caries.

Title: Modular expandable digital single-stage switching network in atm (asynchronous transfer mode) technology for a fast packet-switched transmission of information
Inventor: HINTERBERGER CHRISTIAN
IPC: H04L12/54
Filed: 1989-12-21
Granted: 1999-11-16
Abstract: A modular expandable digital single-stage switching network in ATM (Asynchronous Transfer Mode) technology for a fast packet-switched transmission of information, having a single type of switching module with storage function, which can be operated in two different operating modes (M1, M2) as a pre-switching module or as a final switching module, and has N first inputs, N expansion inputs, N first outputs and N expansion outputs. A first operating mode (M1) realizes the function of the switching module as the final switching module for the switching of N first input lines and N expansion input lines to N first output lines, and a second operating mode (M2) realizes the function of the switching module as the pre-switching module for the pre-switching of N first input lines and for connecting through N expansion input lines. The switching module functioning as the pre-switching module can read in 2N packets simultaneously and read out N packets simultaneously. The switching module functioning as the pre-switching module processes with its header information filter only a part of the header information of data packets for switching the packets to the respective switching matrix column, so that the lines of the matrix column are shared by packets for this matrix column. To avoid so-called packet overtaking, the chronological sequence of packets arriving in each case on one of the N first input lines of the switching module functioning as pre-switching module is replaced from case to case by a spatial ordering on the N first output lines of the switching module functioning as pre-switching module.     The switching module functioning as final switching module can read in 2N packets simultaneously. The switching module functioning as the final switching module processes with its header information filter another part of the header information for the final switching to a matrix output.

Title: Method for preventing steam channelling into a non-aquifer bottom water zone
Inventor: ALAMEDDINE BASSEM RIAD
IPC: C09K8/88
Filed: 1989-12-28
Granted: 1997-07-01
Abstract: A process for closing pores in a bottom water zone where steam is directed so as to by-pass a zone of the formation containing hydrocarbonaceous fluids.  Once a portion of the bottom water zone has reached a temperature in excess of about 300°F, steam entry is ceased.  Afterwards, a temperature activated gellable composition is placed into the bottom water zone.  When the composition reaches that portion of the bottom water zone where a temperature in excess of about 300°F has been reached, the composition activates and forms a rigid gel.  Thereafter, a steam flooding method is commenced.  Steam is diverted from the bottom water zone and into an upper zone containing hydrocarbonaceous fluids.

Title: Adjustable video/raster phasing for horizontal deflection system
Inventor: CHRISTOPHER TODD J
IPC: H04N3/30
Filed: 1991-03-21
Granted: 1995-10-24
Abstract: Adjustment and maintenance of a phase relationship between a video signal and a scan synchronizing signal to assure proper horizontal centering is provided in a horizontal deflection system. A first phase locked loop generates a first timing signal at a first frequency, synchronously with a horizontal synchronizing component in a video signal. A presettable counting circuit operates synchronously with the first timing signal for dividing a clock signal to generate a second timing signal at a second frequency. A second phase locked loop generates a scan synchronizing signal from the second timing signal. A microprocessor may supply different numbers to a register, the output of the register being coupled to the presettable counting circuit. Different numbers change the relative phase between the first and second timing signals by incremental steps. The microprocessor monitors a video source selection switch to gate one of alternative video sources as a video and synchronizing signal output and adjusts the relative phase between the horizontal synchronizing component of the selected video source and a synchronous timing signal by a factor appropriate for the selected video source. A manually operable circuit may be coupled in a feedback path of the second phase locked loop for adjusting the relative phase between the second timing signal and the scan synchronizing signal, over a range corresponding to an incremental step.

Abstract: An environmental monitoring well housing and protection method.  A housing is disposed over the end of an environmental monitoring well pipe and set in concrete along with the well pipe itself so that the space between the housing and the well pipe is filled with concrete below the end of the well pipe.  Fins extend outwardly from the housing into the concrete to anchor the housing.  The housing has an interior ledge for receiving and supporting a cover.  A flexible gasket is placed on the ledge, the cover is placed on the flexible gasket, and the two are fastened down by a pair of bolts that screw into threaded bores in the ledge.  The bolts have five-sided heads and a special tool is provided for installing and removing them. The cover thickness is substantially the same as the distance from the top of the housing down to the ledge, so that where the top of the housing is mounted flush with the ground the top of the cover is also flush with the ground. The cover includes recesses for the heads of each of the bolts, so that the resultant well head is entirely flush with the surface of the ground.  The flexible gasket has an adhesive material on its underside for attachment to the ledge.  Apertures in the cover through which the bolts extend are sized to receive a tip of the special tool for use in lifting the cover.

Filed: 1992-03-10
Granted: 2004-10-19
Abstract: A high pressure fitting is provided which comprises an adjustment nut with nipples extending therefrom in axial extension of one another. The nipples are provided with exterior threads and with conically shaped ends which are respectively engaged by ferrules. Each of these ferrules is engaged by a coupling member having an interior thread which is in engagement with the threads provided on the associated nipple. Adjustment of the threads operates to pull the ferrules against the associated nipples. On each nipple is mounted a frusto-conical ramp adjacent which is provided with a cylindrical arrangement of spaced fingers or a thin wall cylinder having protruding tips directed radially inwards. These fingers or the cylinder with their respective tips ride up the ramps and are loosely accommodated in their respectively associated nipples to prevent accidental detachment thereof. The fingers pressing against the ramps serve to vector forces to remove play from between the inter-engaged threads. In some embodiments, the ferrule can be omitted.
