Patent CA-2125280-A1 (CA)
Title: Apparatus and methods for processing scrap tires
Inventor: CARPENTER ROLAND K
IPC: B29B13/02
Filed: 1993-08-16
Abstract: An apparatus (10) for liquifying tires is shown in a first form including a plurality of tire modules (12) holding tires which are immersed in and preheated by a slurry located in a tank (22).  After preheating, the tire module (12) and tires held thereon are removed from the preheat tank (22) and are immersed in a slurry located in a high temperature tank (28). The temperature of the slurry in the high temperature tank (28) is sufficient to liquify the tires. As the tires liquify, the slurry produced is retained in the high temperature tank (28) to immerse further tires and also overflows from the high temperature tank (28) to the preheat tank (22) and then to a storage tank (36). The slurry from the storage tank (36) can be pumped to the burner (42) of the heat exchanger (48) for heating the slurry in the high temperature tank (28) or can be used for other purposes. In an alternate form, the apparatus (10) includes a vertical stack of tires held in a basket (64) removably supported in a tank (62), with the height of the stack being greater than the outlet (74) of the tank (62) and the level of the slurry located in the tank (62). Thus, the tires above the slurry are preheated prior to being immersed in the slurry and act as a weight to move the stack of tires downward as the lower tires in the slurry are melted.

Title: Apparatus and method for providing a secure gateway for communication and data exchanges between networks
Inventor: VU HUNG T
IPC: H04L29/06
Filed: 1994-11-18
Abstract: An apparatus and method for providing a secure firewall between a private network and a public network are disclosed. The apparatus is a gateway station having an operating system that is modified to disable communications packet forwarding, and further modified to process any communications packet having a network encapsulation address which matches the device address of the gateway station. The method includes enabling the gateway station to transparently initiate a first communications session with a client on a first network requesting a network service from a host on a second network, and a second independent communications session with the network host to which the client request was addressed. The data portion of communications packets from the first session are passed to the second session, and vice versa, by application level proxies which are passed the communications packets by the modified operating system. Data sensitivity screening is preferably performed on the data to ensure security. Only communications enabled by a security administrator are permitted. The advantage is a transparent firewall with application level security and data screening capability.

Title: Charging metal solids into molten metal
Inventor: BROWN WARWICK NICHOLSON
IPC: C22B21/00
Filed: 1993-08-18
Abstract: A furnace (1) has a main holding portion (2) and a charging well (4) into which molten metal from the holding portion is circulated by means of an electromagnetic pump (7). Metal enters the well as a tangential flow and a stationary turbulator (10) is located in the path of the flow so as to upwardly and transversely deflect the flow.

Patent CA-2148186-A1 (CA)
Title: Processor board having a second level writeback cache system and a third level writethrough cache system which stores exclusive state information for use in a multiprocessor computer system
Inventor: JACKSON MICHAEL T
IPC: G06F12/0831
Filed: 1995-04-28
Abstract: A computer system which utilizes processor boards including a first level cache system integrated with the microprocessor, a second level external cache system and a third level external cache system.  The second level cache system is a conventional, high speed, SRAM-based, writeback cache system.  The third level cache system is a large, writethrough cache system developed using conventional DRAMs as used in the main memory subsystem of the computer system.  The three cache systems are arranged between the CPU and the host bus in a serial fashion.  Because of the large size of the third level cache, a high hit rate is developed so that operations are not executed on the host bus but are completed locally on the processor board, reducing the use of the host bus by an individual processor board.  This allows additional processor boards to be installed in the computer system without saturating the host bus.  The third level cache system is organized as a writethrough cache.  However, the shared or exclusive status of any cached data is also stored.  If the second level cache performs a write allocate cycle and the data is exclusive in the third level cache, the data is provided directly from the third level cache, without requiring an access to main memory, reducing the use of the host bus.

Title: Shield for a line side of a circuit breaker for supporting cable and deflecting ionized gases
Inventor: ROWE NEAL EDWARD
IPC: H01H11/00
Filed: 1995-10-11
Abstract: A shield structure on the line side of a circuit breaker has several adjacent channels for carrying ionized gases and cables electrically connected to a line terminal assembly. The shield structure has a main portion and a stepped portion which directs the channels and, thus, the cables and the ionized gases to the rear of the circuit breaker. The main portion has sidewalls, a top wall, and inner walls which form compartments, and which communicate with the walls of the circuit breaker to enclose a pole unit for each of the line terminal assemblies. In each compartment of the main portion of the shield structure, a hanging barrier is disposed between the entrances to the channels for the cables and those for the ionized gases, and cooperates with a flexible member associated with the line terminal assembly to separate the vented ionized gases from the cable line connection, and a hanging lug with an aperture, abuts a tube leading into the line terminal assembly to contain the ionized gases in an area between the barrier and the lug to direct the flow of ionized gases into the channels and to separate the gases from the cable connection. A second embodiment of the present invention has transverse channels for receiving the cables in the top of the circuit breaker.

Title: Nitrite-based corrosion inhibitors with improved anodic and cathodic inhibiting performance
Inventor: BERKE NEAL S
IPC: C04B24/02
Filed: 1996-07-18
Abstract: Mixed anodic/cathodic corrosion inhibitors for use in hydraulic cement, comprising a) a first component consisting of an amount of alkali or alkaline earth metal nitrite sufficient to inhibit anodic corrosion; and b) a second component comprising an agent that acts to increase the anodic corrosion performance of the first component; wherein said first and second components are present in a weight ratio of from about 1:0.1 to 1:1. Optionally an EO/PO superplasticizer can be incorporated where the weight ratio of the first component, i.e., nitrite, to EO/PO superplasticizer is from about 1:0.005 to 1:0.25, with the surprising benefit of increased protection against cathodic corrosion without harming the level of anodic corrosion inhibition.
