Patent CA-1112719-A (CA)
Inventor: SCHWARTZ RALPH E
IPC: H01M2/38

Abstract: ABSTRACT OF THE DISCLOSURE An ambient temperature electric cell of primary and secondary nature, characterized by the use of a dithionite radical of an alkaline metal as the charge transfer agent, and including processes for manufacturing and for operating the same.  The dithionite is dissolved in an anhydrous electrolyte comprised of a suitable solvent, which may also contain a salt of the same alkaline metal and be saturated with sulfur dioxide.    A sealed and evacuated cell (negative electrode, inert highly porous space, and positive current gathering electrode) is filled with the electrolyte and subjected to a charging current sufficient to plate the alkaline metal onto the negative electrode while further saturating the electrolyte with sulfur dioxide.  In the case of a secondary cell, the electrolyte is capable of redissolving the dithionite produced upon discharge, such procedure being enhanced by a system for forced circulation of the electrolyte.  In the case of a primary cell, redissolution is not necessary and the final cell potential and discharge character-istics can be enhanced by replacing the dithionite electrolyte with other anhydrous electrolyte solutions (e.g., sulfuryl chloride or thionyl chloride).  The cell is characterized by extremely low internal resistance, long shelf life, excellent performance over a wide temperature range, and negligible depletion of the active dithionite charge transfer agent.  In a particular high energy battery system, an electrolyte containing dissolved dithionite is circulated between a battery chamber and an auxiliary chamber containing solid dithionite salt (e.g., lithium dithionite).  The electrolyte circulates from the auxiliary chamber through a solids separating means (centrifugal separator) to the battery chamber, where the electrolyte containing freshly dissolved dithionite is passed through a highly porous intermediate passage between an elongate active anode (e.g., copper) and an adjacent elongate current gathering cathode (e.g., finely divided carbon), in such fashion as to minimize internal resistance to current flow while substantially increasing the energy storage capacity of the battery cell.

Abstract: GOVERNORLESS GAS TURBINE FUEL CONTROL                     ABSTRACT     Fuel flow to a gas turbine engine is controlled in response to power lever position and CDP.  Fuel is supplied to the engine through three fuel flow regulating circuits which are in parallel.  In one of these circuits there is a valve which establishes a minimum fuel flow which decreases with increasing power lever advance.  In a second circuit there is a valve which modifies fuel flow in response to CDP.  In a third circuit there is a valve which modifies fuel flow in response to CDP and receives fuel from a valve which opens with increasing power lever advance.  The fuel control system includes a low power sensitive torque motor which may be activated to increase the pressure drop across the three circuits. whose flow thus increases proportionally.  Normal engine operation is obtainable without the use of the torque motor which provides an interface to an electronic control unit which senses various engine and ambient parameters and activates the torque motor in order to modify fuel flow accordingly.

Granted: 1983-05-24
Abstract: ABSTRACT OF THE DISCLOSURE:          An arrangement for measuring the distance of two oppositely arranged roller ways of a continuous casting plant comprises a measuring body capable of being pulled or pushed through the section between the roller ways. The measuring body has oppo-sitely arranged contact surfaces touching the surface areas of the rollers, the distance-measuring device being fastened with-in the measuring body. In order to be able to determine the distance of the rollers with the greatest accuracy possible also with rollers that are not arranged opposite   each other, the contact surfaces of the measuring  body are comprised of elastically deformable spring steel strips whose longitudinal extension is larger than the axial distance of three neighbouring rollers of one of the roller ways. The spring steel strips are pressable towards the surface areas of the rollers by pressure units arranged between them and the distance-measuring device contacts the inner side of one of the spring steel strips.

Abstract: ABSTRACT An energy conserving circuit for controlling supply of electrical power to various loads such as a street lamp or a hot water heater comprises a photoelectric device for starting a timer when a change from daylight to dark is sensed at sundown, and a load power control responsive to the timer to switch between power-of and power-on states.  With a street lamp the timer and power control means are connected to switch the power control means to power-on state at the beginning of the delay period at sundown and later, well before sunrise, to switch to power-off state.  In the case of a household hot water heater the switching of the power control to power-on state is delayed until the peak demand hours have ended after sundown.  The photoelectric device will normally cause the power control to switch to power-off state at sunrise.  However, a second timer may be added which is responsive to the photoelectric device to start a second timing period ending after normal sunrise so that switching to power-off will occur if the photoelectric device does not or cannot respond to sunrise.

The retention means gripingly engages the wheel.  A central portion is disposed axially outward from the rim portion and has a central aperture therethrough.  The aperture is in axial alignment with the axle upon which the wheel is rotatably mounted.  A locking pin is slidably dis-posed within the aperture.  The locking pin has a head portion at its outward facing end and a reduced portion at the inward facing end.  A locking cap is fixedly attached to the inward facing end of the reduced portion of the locking pin.  The locking cap is provided with a plurality of radially project-ing bayonet tabs.  The head portion is positioned outboard of the central portion of the wheel cover and captures a spring between the central portion and the inwardly facing radial-ly extending portion of the head portion in combination with a funnel shaped member provided with a radially projecting col-lar having a plurality of holes provided therethrough for re-gistration on the threaded studs to which the wheel is fixedly mounted to rotate with the wheel.  Nuts positionally lock the funnel shaped member on the studs wherein the central axis of the funnel shaped member is coincident with the axis of the axle and the locking pin.  The funnel shaped member flares in-wardly to surround the end of the axle and terminates in an inwardly radially projecting lip.  The inwardly radially pro-jecting lip is provided with a plurality of slots therethrough to receive the radially projecting bayonet tabs of the locking cap when the locking cap is pressed inwardly against the bias-ing force of the spring. The bayonet tabs slidably en-gage an inclined track as the locking pin is rotated about its axis.  The track has a detent for lockingly positioning the bayonet tab therein to thereby positively lock the wheel cover to the funnel shaped member and, in turn, to the wheel member.

The channels are preferably apertured to such an extent that the total open area for an inlet stream flow on the channel side of the screen is less than the open area of the slots on the wire side of the screen.  Thus, the pressure drop through the screen is controlled by the apertures in the channels with the result that the screen surface can be provided with slot widths of optimum size relative to the particle size of material to be contacted thereby.
