Patent CA-2040514-A1 (CA)
Inventor: LAMBERT SUSAN L
IPC: C07C4/06
Filed: 1991-04-15
Abstract: This invention relates to novel silicon enhanced aluminas (SEAL) and processes to prepare them. The SEAL compositions have a bulk empirical for-mula of Al2-xSixO3Fx where x varies from about 0.01 to about 0.5. This SEAL material has a three-dimensional pore structure with the pores having diameters in the range of about 20 to abut 300A, a crystal structure characteristic of alu-mina, and where the surface of the SEAL has a higher silicon concentration than the interior of the SEAL. The SEAL is prepared by contacting an alumina with a fluorosilicate salt. This SEAL can be calcined to give a calcined seal with a formula Al2-xSixO3Fy where x is as defined above and y varies from 0.01 to x. The calcined SEAL contains both strong and weak acid sites. These SEAL compositions are useful as hydrocracking catalysts.
Patent CA-2041753-A1 (CA)
Inventor: TUUSA HIEKKI
IPC: H02M7/219
Filed: 1991-05-02
Abstract: Procedure for regulating the d.c. voltage of a pulse-width modulated rectifier bridge controlled by self-commutated  semiconductor  components  and  provided  with filtering coils, in which procedure the phase voltages of the supplying three-phase mains and the d.c. voltage of the rectifier are measured.  The modulation references needed for the pulse-width modulation are produced using pure sine and cosine curves synchronized with the mains voltages, with spatial vectors formed from them or with components of such vectors,  by means of  a phase-locked  loop.   The regulation is effected in a coordinate system tied to the spatial vector of the mains voltages.

Title: Fast cure and pre-cure resistant cross-linked phenol-formaldehyde adhesives and methods of making same
Inventor: CALVE LOUIS R
IPC: C09J161/10
Filed: 1991-05-13
Abstract: Fast cure and "pre-cure" resistant thermosetting adhesives and methods for their production useful for binding lignocellulosic materials together, are disclosed.      A fast curing adhesive is obtained by cross-linking binary phenol-formaldehyde consisting of high average molecular weight phenol-formaldehyde (PF) resin and low average molecular weight PF resin with lignin. A  "pre-cure" resistant adhesive is obtained by cross-linking a PF resin, such as binary phenol-formaldehyde, with a lignin with the addition of ammonia preferably in the form of an ammonium salt. The lignin may be obtained from different wood pulping waste materials including that recovered from the sulphite, kraft, organic extract or steam hydrolysed wood pulping processes. The adhesive can be produced as an aqueous solution or dispersion, and used in either a basic or acidic environment. The quick setting and "pre-cure" resistant adhesives are inexpensive to produce and both display improved adhesion characteristics when compared with existing adhesives prepared from wood waste products. The adhesives also compare advantageously to a variety of existing commercial phenolic resin presently being used in the manufacture of wood composite products such as waferboards. These adhesives are capable of being spray dried more easily and produce higher yields, when compared with existing wood waste products which have been cross-linked with commercial PF resin or to a variety of existing commercial phenolic resins.

Patent CA-2052154-A1 (CA)
Inventor: MANESS RONALD C
IPC: C02F1/52
Filed: 1991-09-24
Abstract: New systems for the purification of liquids containing suspended solids and/or dissolved solid materials basically include a conical flocculator unit and a conjoined conical clarifier unit. The flocculator has a cylindrical lower portion, frustum middle portion and large diameter cylindrical top portion while the clarifier is essentially a large diameter cylindrical top portion over a lower frustum portion. Water or other liquid to be purified enters the flocculator lower portion via opposed, unequally sized nozzles to assume a helical flow upward past a series of deflector plates positioned at the top of the lower flocculator portion while a sludge blanket forms therein. A double flume plus slot arrangement located at the junction of the flocculator with the clarifier separates solids from liquid as fluid flow from the flocculator passes into the clarifier where it is subjected to further separation of sludge from clarified liquid with part of the sludge being recycled to the flocculator. New purification methods operated with the new systems are also disclosed.

Title: Object identification system for warehouses or supermarkets or personnel or suchlike
Inventor: MARSH MICHAEL J C
IPC: G07B15/06
Filed: 1992-01-02
Abstract: An identification system comprises an interrogator and a number of transponders. The interrogator includes a transmitter (10) for transmitting an interrogation signal to the transponder, and a receiver (16,18,20,22) for receiving a response signal from the transponder.

Each transponder comprises a receiving antenna (30) for receiving the interrogation signal, a code generator (36), a transmitting antenna (32), and a modulator (40) connected to the code generator. On receipt of the interrogation signal the transponder repeatedly transmits a response signal containing data which identifies the transponder. The interrogator detects successful identification of any transponder and briefly interrupts the interrogation signal to indicate the successful identification. Each transponder includes a logic circuit (42) responsive to a respective interruption in the interrogation signal to cease transmission of its own response signal. <IMAGE>

Title: Access door with safety latch for pressurized air chambers
Inventor: GAYHART EDWARD E JR
IPC: E05C3/04
Filed: 1992-07-06
Abstract: ABSTRACT OF THE DISCLOSURE      An access door assembly for a pressurized wind-box, comprising a door frame having an opening with a post extending from the door frame. A door is pivotally mounted to the frame at a hinge.  A latch is pivotally mounted to the door and includes a hook which engages the post for locking the door to the frame.  The latch also includes a catch member extending beyond the hook for catching the post when the latch is moved to unlock the  door.   This  stops  the door  in an  intermediate partly open position allowing gusts of air to blow through  the  opening  thereby  giving  the  operator  a warning and  indication that the windbox  is in fact under  pressure.   In  this  manner,  an  operator  has sufficient time to step out of the way before moving the latch further, thereby fully disengaging the latch from the post and allowing the door to open fully.
