Title: Method and apparatus for measuring mass flow
Inventor: DELSING JERKER
IPC: G01F1/86
Filed: 1989-10-30
Abstract: ABSTRACT      In a method for measuring the mass flow M of a fluid flowing through a pipe having a cross-sectional area A, the sound velocity c2 in the fluid is determined as well as the flow velocity v of the fluid by sing-around technique. Further, reflection technique is used which comprises measuring the amplitude both of an ultrasonic pulse which has been reflected in a boundary between a first and a second material having different acoustic impedances, and of an ultrasonic pulse which has been reflected in the boundary between the second material and the fluid, it being possible to determine the density of the fluid on the basis of the measured amplitudes, the sound velocity c2 in the fluid and the acoustic impedances of the first and the second material. The mass flow M is then obtainable as M = v x A x ?2.     A mass flowmeter especially has a transducer with a piezoelectric crystal (5), a first block (6) of a first material disposed adjacent said crystal, and a second block (7) of a second material disposed between the first block and the fluid, and calculating and amplitude metering means (10 and 12).

Patent CA-2007325-A1 (CA)
Inventor: DENT PAUL W
IPC: H04L27/233
Filed: 1990-01-08
Abstract: The invention relates to a method and arrangement for rapidly controlling the frequency of a radio-receiver which receives signal sequences that have been subjected to interference and which includes a synchronizing sequence and a data sequence. The signal sequence is converted in an A/D-converter to provide signal points (ET) which are intended for analysis, and a Viterbi-algorithm is adapted with the aid of adaptation signals obtained from the synchronizing sequence of the prevailing interference.  The data sequence is Viterbi-analyzed through a large number of calculating stages, for the purpose of determining the bit sequence (S1) of the data sequence.  The signal-point (ET) is branched-up to branch-signal points (ET), the number of which is equal to the number of states of the Viterbi-algorithm.  Each individual branch-signal point is phase-shifted to a corrected signal point (ET,1), and is compared with its adaptation signal, which has (K) separate signal points.  Distances (.DELTA.ST,1K) and angular deviations (.DELTA..PHI.T,1K) are calculated between the corrected signal point and the adaptation signal (U1K) signal points.  A transition (K1) is selected through the Viterbi-algorithm, with the aid of the distances (.DELTA.ST,1K) and the angular deviation (.DELTA..PHI.T,1K), corresponding thereto is selected. Selected angular deviations (.DELTA..PHI.T,1K), for successive incoming signal points (ET) are low-pass filtered and integrated to form a phase correction signal (V) through which the phase of the successively incoming branch-signal points (ET) are shifted.  Corresponding phase correction signals are calculated for the remaining states of the Viterbi-algorithm.

Title: Measuring and controlling the thickness of a conductive coating on an optical fiber
IPC: C03C25/12
Filed: 1990-05-23
Abstract: A method for manufacturing a coated optical fiber includes depositing aconductive coating on the optical fiber and measuring a value of conductance of that coating. Featured within the manufacturing method is a method for measuring the thickness of the conductive coating on an insulator, e.g., carbon on an optical fiber, including the following steps. An electromagnetic field is established by an input signal. The conductively coated insulator is moved through the energized electromagnetic field. The conductive coating on the insulator is oriented with respect to the electric field so that their interaction increases transmission loss from input to output. An output signal is extracted from the electromagnetic field. From changes in the output signal with respect to a predetermined standard, or reference, the conductance and the thickness of the conductive coating are determined. From the measured thickness of the coating, a control signal is generated for dynamically controlling one or more of the process parameters for depositing the coating on the insulator from a precursor gas. The coated insulator continuously moves through the apparatus without any physical contact. No interruption of the production process occurs.

Title: Portable and dynamic distributed applications architecture
Inventor: WHITE JOHN W
IPC: G06F9/44
Filed: 1990-09-12
Abstract: ABSTRACT OF THE DISCLOSURE      A system  and  method   is  disclosed  for  enabling  a plurality  of computers  and associated  computer resources, some or all of which may  be of heterogeneous configuration, to cooperatively process a variety of applications such that the execution is transparent to the user regardless of where the  application  is  actually  executing.  This distributed applications  architecture  performs  an information distri-bution   service  between  multiple  transaction  processing systems by working with a transaction processor via communi-cation  channels  to  other  hosts  within the network and a dialog  manager  (26)  which  uses  a  transaction processor interface   (78)   to   communicate   with  the  transaction processor.   Additionally,  the  architecture  employs a map service  (36,40) to  provide an  editor to allow application programmers  to  create  the  maps  (40) for the application panels,  a compiler to generate the maps into linkable form, and  a  linkable  interpreter  which translates the linkable form into the screen presentation  format for that platform. Furthermore,  to distribute an  application, the source code for the procedures  (32), views (38) and panels are moved as a block to  the new system.   This is possible  because once the application source code is complete, all of the applica-tion logic, user interface control tables, view definitions, and  other application-specific  tables for  one transaction definition are packaged by the present invention in a single load module on the system where the application will reside. The load  module is them compiled  using the target system's compiler,   link  editor,  and   bind  process.   Thus,  all environment-dependent variations of import/export, including network protocol, operating systems, processor types, etc., are automatically  integrated with  the application  at load module  bind time.   Therefore, no  source code  changes are necessary.

Title: Device for Raising and Supporting the Foundations of a Building
Inventor: GOSSELIN CONRAD
IPC: E02D31/00
Filed: 1990-11-28
Abstract: Stabilization   of    sagged   building foundations is carried out by raising and supporting these concrete foundations.   To that effect, an L-shaped lifting assembly is bolted to the concrete to support the foundations.   This lifting assembly is also formed with a vertical tubular member in which a tubular pile can slide longitudinally.  An assembly of two pivotal jaws, positioned on opposite sides of the pile, is mounted above the lifting assembly. In order to drive the pile into the soil, a pair of hydraulic cylinders interconnect the lifting and jaw assemblies. As the cylinders extend, the jaws pivot to enable the jaw assembly to slide upwardly over the pile.  As the cylinders retract, the jaws pivot to grasp the pile and drive it into the soil.  When the lower end of the pile reaches soil of sufficient hardness,  further retraction  of  the hydraulic  cylinders  raises  the lifting  assembly  and accordingly the  foundations. When the foundations have been adequately raised, the pile and the tubular member, both made of steel, are welded together to stabilize the foundations.

Title: Absorption filter for color display devices
Inventor: SCHOTT DAN J
IPC: H01J29/18
Filed: 1990-04-26
Abstract: A contrast enhancement filter (24) for color displays, particularly adapted for color CRT tubes (10) of the shadow mask type. A  transparent plate (40) has applied thereon absorptive areas (42), each area dyed with a primary color corresponding to the color dots (46) of the CRT display face and a plurality of such color areas (42) randomly disposed over each color dots (46). Since the absorption areas (42) are spacially independent, each color area (42) acts independently of the others. The filter (24) provides bandpass efficiency comparable to monochrome filters, and has a broad viewing range essentially independent of angle of vision. In a further embodiment, colored oriented fiber-optic elements (58, 60, 62) are disposed over the phosphor dots (50, 52, 54) in a predetermined array, allowing the filter plate (56) to replace a conventional faceplate and filter combination structure, while providing a selective viewing angle of high contrast. The filter (24) is suitable for any light-responsive display screen, also including liquid crystal elements.
