Granted: 2007-06-26
Abstract: A slide gate valve having a cementless joint between the valve and a metallurgical vessel containing molten metal is provided for facilitating the replacement of worn refractory components in the valve. The slide gate valve generally comprises a fixed refractory plate having a flow opening disposed generally in alignment with a tap opening of the metallurgical vessel, a movable refractory plate having at least one flow opening, an air cylinder for reciprocally moving the movable plate with respect to the fixed plate to control the overlap of the flow openings in order to modulate a flow of molten metal through the valve, a spring assembly for pressing the movable plate against the fixed plate to provide both static and dynamic seals between the plate, and a cementless joint between the flow tap of the metallurgical vessel and the fixed refractory plate formed by joint surfaces on the flow tap and the fixed plate which are compressively engageable to form a molten metal tight joint therebetween and compression means, which may be a spring arrangement, for sealingly compressing the mutually-engageable joint surfaces to create a joint without the need for extraneous adhesives or cement. In the method of the invention, the compression means of the joint preferably acts on the fixed plate when the plate is laterally slid away from the flow tap incident to a replacement operation to wipingly clean the joint surface of the flow tap of the metallurgical vessel.

Granted: 2000-06-06
Abstract: To carry out a process for regulating individual factors or all factors influencing combustion on a furnace grate, a radar device (22) is provided primarily. This radar device (22) serves to detect the three-dimensional distribution of the fuel mass on at least one preferred region of the grate. In addition, an infrared camera (23) is provided for supplying information on the burn-up behavior of the fuel located on the grate. By using the measured quantities obtained from these two devices, control variables may be derived within a regulating unit for influencing the grate speed, the charging device, the amount and composition of supplied primary air, the amount and composition of supplied secondary air, the speed of the ash roller and the temperature of the air preheating device so that the furnace performance can be adapted to the steam output requirement. In addition to improving the fuel burn-up on the grate, it is also possible to influence the exhaust gas in an advantageous manner, for instance, with respect to the formation of unburned gas components and nitrogen oxides.

Title: Vehicle bumper with foam and method and apparatus for manufacturing
Inventor: ROSASCO JAMES J
IPC: B60R19/18
Filed: 1995-01-16
Granted: 2005-07-12
Abstract: A bumper construction for vehicles constructed of a single strip of metal roll-formed into a completely enclosed tubular member in which a foamed-in-place material is located in and completely fills only a central section of the tubular member a relatively short distance on each side of the central axis of the vehicle. An apparatus is provided for manufacturing roll-formed bumpers partially filled with a foam-in-place material, the bumpers including material defining a continuous closed section defining an open interior and opposing open ends. The apparatus includes a turntable with a plurality of holders including arms shaped to extend partially into the bumpers, and a plug on the end of each arm configured to block off the open interior of the bumper. The holders are pivotally mounted on the turntable so that a bumper can be slipped onto a selected holder, pivoted to an upright position, and then rotated by the turntable under an injector for dispensing foamable reaction injectable urethane (RIM) material. The plug is squeezed and thus expanded to seal off the interior space, after which the RIM material is dispensed into the upright open end. The upright position is held for several seconds to allow the RIM material to cure, and then the holder is then pivoted down so that the bumper can be readily removed. A method corresponding to the above-noted apparatus is also disclosed.

Title: Apparatus and method for thermal protection of electric motors
Inventor: FARAG SAMIR F
IPC: H02H7/085
Filed: 1995-05-10
Granted: 1999-01-05
Abstract: An apparatus for thermal protection of an electric motor  is  provided,  including  a  monitoring  device  for generating a signal representative of the current in a conductor supplying electrical power to the electric motor. A control circuit processes the current signal and utilizes the  processed  signal  and  motor  thermal  parameters, including the thermal resistance and thermal capacitance of the  rotor,  to  generate  signals  representative  of  the temperature of at least the rotor.  A comparator circuit, which may be part of the control circuit, compares the temperature  signals  to  reference  maximum  temperature signals and produces a control signal when the temperature signals  and reference  signals  satisfy  a  predetermined relationship.   The control signal may be applied to a contactor to interrupt current to the motor.  A method for thermal protection of an electric motor is also provided, including thermal modeling of the rotor temperature.
Patent CA-2151401-C (CA)
Inventor: WEICHERT BERTHOLD
IPC: F41A9/33
Filed: 1994-10-06
Granted: 1999-08-17
Abstract: The invention relates to a self-loading grenade launcher with a cartridge belt feed device which conveys a cartridge by means of pawls engaging in the cartridge belt preferably horizontally to the front of a cartridge chamber, in which the pawls are borne by two counteracting slides movable transversely to the direction of fire and arranged in a hinged cover and project downwards. An inertia bolt runs forward along a path from a release position against the cartridge chamber under the force of one or preferably two return springs and is fitted so as to slide the cartridge conveyed from the cartridge belt by the pawls into the cartridge chamber during this forward movement and, owing to the recoil force due to the firing of the cartridge, to run back along the path and thereby retensioning the return spring(s). A control system coupled to the inertiabolt and the slides converts the forward and recoil movement of the bolt into the transverse alternating movement of the slides. A firing device comprises a firing pin which is tensioned by a percussion spring and held by a detent in the tensioned state, whereby the detent is released and the cartridge fired before the inertia bolt has completed its forward travel but only after the cartridge has penetrated far enough into the cartridge chamber to hold the gas pressure resulting from firing. A housing secured to the cartridge chamber extends along the bolt path and partially surrounds it, the longitudinal axis of which continues the central axis of the cartridge chamber.

Abstract: A high-speed secondary cell charging system is provided which accurately measures the amount of time to achieve a full-charge condition in a secondary cell. In this system, when charging a secondary cell while detecting a charging characteristic of the secondary cell, charging is performed of the secondary cell using a prescribed amount of charging current. Then, when a prescribed condition with regard to the secondary cell is detected, the secondary cell is charged once again, this time with a current that is smaller than the previous charging current. When a condition indicating the completion of the charging of the secondary cell is detected, the charging is stopped. If this condition is not detected, a yet smaller charging current is set and the charging of the secondary cell is performed once again, the above operations being repeated until a condition which indicates that the charging of the secondary cell is complete is detected.
