Patent CA-2020580-A1 (CA)
Inventor: THOME ROLAND
IPC: B01J29/08
Filed: 1990-07-06
Abstract: 2.1. Zeolites are microporous crystalline aluminosilicates which are distinguished by a number of particular properties. They have a defined cavity system with orifices of 0.3 to 0.9 nm. They are cation exchangers. In the H form, they have high acidity in the solid state. The hydrophobic character can be controlled by the ratio of silicon to aluminium. They exhibit high thermal stability. These substances were generally prepared only with the addition of organic, structure-controlling compounds to the synthesis mixture. Processes which dispense with the use of these organic substances, for example US 4,257,885, lead only very slowly (after several days) and generally incompletely to the desired product. Furthermore, the occurrence of undesirable secondary phases cannot in general be ruled out. The present invention relates to a purely inorganic synthesis process which virtually completely excludes the formation of secondary phases and which can be carried out in a short time. 2.2. The zeolites prepared by the process according to the invention have a chemical composition which can be described as follows in molar ratios: 0-3M2O : Al2O3 : 15-40SiO2 : 0-40H2O, in which M denotes an alkali metal cation. These zeolites can be subjected to exchange with the aid of a mineral acid, an ammonium compound, other proton donors or other cations. In conjunction with the above chemical composition and the interplanar spacings listed in Table I, the zeolites prepared according to this invention have, in the 29-silicon solid state Mas nuclear resonance spectrum, adsorption bands at about -100, -106, -112 and -116 ppm, based on tetramethylsilane as standard, with the aid of which this novel aluminosilicate can be distinguished from all similar zeolites (Fig. 1 and 2). 2.3. Because of these structural units, the zeolite catalysts prepared according to the invention have a much higher catalytic activity than similar pentasils prepared by conventional methods.  3.

Abstract: A non-woven matrix of sized bushing glass and synthetic fibers provides a rigid but resilient product having good strength and insulating characteristics. The product finds particular application in large area panels such as vehicle headliners. The matrix consists of glass fibers, first, solid or hollow homogeneous synthetic fibers such as polyester, nylon or Kevlar and second, bi-component synthetic fibers which have been intimately combined with a thermosetting resin into a homogeneous mixture. The bi-component synthetic fibers include an outer low melting temperature sheath and a higher melting temperature core.   This mixture is dispersed to form a blanket. The blanket may be heated and pressed to cure and form it into a final product in one step on two steps. In the one step process, the curing temperature is sufficiently high to melt the sheath of the bi-component fibers and activate and cure the thermosetting resin. In the two step process, first the sheath of the bi-component fibers is melted to form initial bonds. Subsequently, the thermosetting resin is heated and cured. The product may be utilized in a planar configuration or be formed into complexly curved and shaped configurations. The product may also include a skin, film or fabric on one or both faces thereof.

Abstract: BRIDGE-LIKE INTERNET PROTOCOL ROUTER                ABSTRACT OF THE DISCLOSURE     A device and related method for coupling seg-ments of an extended local area network (LAN) in such a way that message traffic employing inter-network proto-cols such as TCP/IP will be handled without the diffi-culties usually associated with bridges,  and without the complexity and expense of full IP router capabili-ty.  The device operates like a bridge for non-TCP/IP traffic.  For TCP/IP traffic it operates in a bridge-like manner but maintains a database associating extend-ed LAN segment addresses with port numbers in the de-vice,  so that packets can be automatically forwarded over a spanning tree connecting the network segments. A host computer in any network segment can address others in different network segments of the extended LAN as though all were in a single LAN.  The device of the invention functions to block the flow of ARP messages and to generate ARP replies that render the device of the invention transparent to hosts within the extended LAN. The device is also transparent to true IP routers, which may still be used to effect communication with points outside the extended LAN.

Title: Hvac low power usage circulation blower
Inventor: BOWSKY BENJAMIN
IPC: G05D23/275
Filed: 1992-01-09
Abstract: Abstract of the Disclosure A field installable device for a conventional heating and air conditioning system (HVAC) is provided which operates a blower fan in conjunction with a standard thermostat.          Presently, HVAC systems operate in four modes: heating, cooling, off and fan "on".  The device includes a multi-pole, multi-speed motor and a control operatively connected between the thermostat and the motor.  With the fan switch in the "on" position and heating or cooling called for, the control causes the blower to operate at a high speed, which may be different for heating or cooling.  When the pre-selected temperature is reached the particular thermal operation (i.e., heating or cooling) is stopped.  The control switches the motor to a speed substantially slower than the operating condition speed to provide continuing air circulation until the thermostat again calls for thermal operation.  With the switch in "auto" position, the blower operates similarly to present systems.
