Filed: 1994-10-17
Abstract: ABSTRACT            APPARATUS FOR MANUFACTURING ANNULAR OR TUBULAR WORKPIECES FROM CONCRETE             It is desired to simplify the design of an appa-ratus for manufacturing annular or tubular workpieces from concrete, comprising molding means (1), which have a vertical axis and between a core (2) and a shell (3), which surrounds and is radially spaced from the core (2), define a mold cavi-ty, which is adapted to be filled with concrete from above, feeding and distributing means (8), which are radially gui-ded relative to the molding means and serve to feed and dis-tribute the concrete which is to be dispensed into the mold cavity, and a molding press (9), which comprises a vertical ram (17) that carries a molding ring (15), which is adapted to close the mold cavity at its top, and which press is ra-dially displaceable relative to the molding means (1). This is accomplished in that feeding and distributing means (8) for the concrete and the molding press (9) are mounted on a carriage (7), which is guided to be radially displaceable re-lative to the molding means (1), and are arranged on said carriage one behind the other in the direction in which it is displaceable.

Patent CA-2122108-A1 (CA)
Inventor: FEINTUCH PAUL L
IPC: F01N1/00
Filed: 1994-04-25
Abstract: An active adaptive noise canceller (100) that does not require a training mode and operates over an extended noise bandwidth.   The canceller partitions the noise bandwidth into frequency sub-bands,  and multiple adaptive filter channels (120, 140) are employed, one for each sub-band, to cancel noise energy in the respective sub-bands.   Each channel includes bandpass filters (121, 130) to restrict the channel to operation over only the particular sub-band, and delays are inserted in the operation of the filter weight updating.  Because each channel is stable over its sub-band, the canceller operates over the extended noise bandwidth of all the sub-bands.

Patent CA-2138727-A1 (CA)
Title: Locally powered control system having a remote sensing unit with a two wire connection
Inventor: TINSLEY TIMOTHY M
IPC: G05D23/19
Filed: 1994-12-21
Abstract: A communication system comprises a remote switching module having two signal terminals connected by just two conductors to the signal terminals of a local decoding module. Power is directly provided only to the local decoding module, which applies DC voltage of a first level across the conductors. The remote switching module has a voltage regulator which provides power of a second voltage level lower than the first level for operating a control unit in the switching module. The control unit controls a variable impedance having higher and lower impedance levels and which is connected across the switching module's signal terminals.  The decoding module can detect the different impedance levels by sensing the current flow on the conductors. The switching module communicates with the decoding module by modulating the time intervals between changes in impedance levels. The system has particular utility for retrofitting cooling to a heating systems where preexisting thermostat wiring has only two conductors, say when an air conditioning function is added to a previously heat only system. The system is also useful when installing electronic thermostats on heating and cooling systems originally controlled by a mechanical thermostat.

Title: Multiple band folding antenna
Inventor: NYGREN EVERT C
IPC: H01Q19/17
Filed: 1995-01-18
Abstract: An antenna has one feed for an S-band electromagnetic signal,  and a second feed constructed as an array of radiators  to  service  two  C-band  signal  channels.    A subreflector having a microwave frequency selective surface (FSS) is placed in front of a main reflector.  The C-band feed is constructed of an array of square aperture horns joined  by  separate  transmit  and receive  barline beam-forming networks,  and a meanderline polarizer to produce circularly polarized radiation patterns.  Tapered ridges extend longitudinally along inner wall surfaces of each of the horns to provide increased bandwidth to the C-band  feed.     The  frequency  selective  surface  is constructed, typically, of a generally planar substrate of material transparent to electromagnetic radiation,  and numerous metallic, generally annular, radiating elements, or resonators, arranged on the substrate in an array of repeating nested sets of the radiating elements.  The lower frequency S-band feed is located behind and to the side of the subreflector for transmission of radiation via a folded optical path to the main reflector.  The C-band feed is located in front of and to the side of the subreflector for transmission of radiation along a straight path through the FSS to the main reflector.  The locating of the two feeds to the slde of the subreflector permits the subreflector to be stowed by folding down upon the C-band feed, and the main reflector to be stowed by folding down upon both the S-band feed and the stowed subreflector.

Filed: 1995-03-01
Abstract: An  improved  method is provided for making thin   film   electrochemical   sensors,   such   as subcutaneous glucose sensors used to monitor blood glucose   levels   in   a   diabetic   patient.      The fabrication method comprises placing a thin film base layer  of  insulative  material  onto  a  rigid  flat substrate, with a curable adhesive interposed between the  perimeter of the  base layer  and  substrate to define a shallow cavity underlying a central portion of the base layer.   The subassembly is subjected to heat and pressure to cure the adhesive, resulting in air expulsion from the cavity such that the central portion  of  the  base  layer  is  drawn  into  intimate contact  with the  substrate.   Appropriate conductor elements for one or more sensors are formed on the base   layer   as   by   conventional   contact   mask photolithography,  and  a  thin  film  cover  layer  of insulative   material   is   applied  thereover   with apertures  in  the  cover  layer  exposing  distal  end sensor electrodes and proximal end contact pads.  The insulative cover and base layers are then cut along a line surrounding each finished sensor which is lifted and separated easily from the substrate.
