Abstract: ABSTRACT OF THE DISCLOSURE A control system for a work-performing vehicle such as a lift truck, front end loader, or the like, including a source of motive power for driving the vehicle, performing work, or the like, and of the type including a sensor having an electrical output providing an electrical output signal having a characteristic whose magnitude varies according to load distribution on the vehicle.  A level detector receives the output signal and provides a further signal, in response thereto, indicative of an unstable load distribution on the vehicle and there is a circuit connected to the output of the level detector responsive to the signal therefrom for disabling the motive power source when the load distribution on the vehicle is unstable to prevent an intensification of the unstable condition.  The system includes an additional level detector receiving the output signal from the sensor for providing a further signal indicative that the unstable load distribution condition on the vehicle is being approached, which signal is issued prior to the signal from the first-mentioned level detector.  The signal from the additional level detector may be utilized to issue an audible or visual warning, retard the speed of the vehicle, or retard the speed of the work-performing means, all prior to disabling of the motive power source.

Title: Process for manufacturing synthetic gypsum  absorbent granules and the liquid absorbent  product resulting therefrom
Inventor: VALENTA RUDOLPH C
IPC: C09C1/02
Filed: 1978-01-30
Granted: 1981-11-24
Abstract: ABSTRACT Synthetic absorbent granules of calcium sulfate dihydrate are manufactured by a process which utilizes a commercial type of dry powdered gypsum plaster or calcium sulfate hemihydrate, mixes the plaster with water in an inclined rotating disc machine to cause hydration to occur, and wherein the plaster is formed and grown into balls or granules of a generally prede-termined size and discharged from the disc when reaching such size.  The ball forming operation is started in the disc with seed material in the form of balls of a size corresponding generally to the balls to be manufactured by the process.  Water spray is applied to the seed material in the rotating disc and a uniform pattern of movement of such material with a well defined eye is developed.  When this occurs, generally the water is turned off.  Dry powdered gypsum plaster is fed to the rotating disc from a position adjacent the base of the eye and then water spray is fed to the disc through a nozzle located so that the water will not strike the eye formation of the moving material.  With the plaster being fed to the disc the seed material balls grow to a size where they are discharged from the inclined rotating disc at a lower portion thereof, and meanwhile the dry powdered plaster coming in contact with the water spray forms into new tiny balls, and these grow as the mix moves in the inclined rotating disc until they reach a size at which they are discharged.  During this operation, while the balls grow in size and the plaster is hydrating, the material in the disc is visually observed, and if the balls or granules are too dry that they are not growing, or if they are too wet that they stick together, of if the eye configuration in the moving material is not proper, adjustments are made in one or more of the processing conditions including the position or amount of the water spray, the position or amount of the plaster feed, the speed of rotation of the disc, or the inclination thereof. When the desired eye configuration is restored from needed adjustments, the balls or granules grow, they are discharged, and they are dried and then screened to the desired size, with large balls or granules crushed and again screened to the desired size.  The screened synthetic balls or granules are ready for marketing and use as absorbents for various purposes including the absorbing of undesirable oil, grease and other liquid accumulations on floors, of animal toilet refuse as in cat boxes, and the serving as carriers for agricultural chemicals to be distributed in such granular form. The invention of this application is an improvement on the subject matter disclosed in United States Patent Number 4163674 of Karl Been, and assigned to Oil-Dri Corporation of America, the assignee of the present appli-cation.    `

Abstract: ELECTROCHROMIC DISPLAY DEVICE                         ABSTRACT In an electrochromic display device, it is desirable that the counter electrode is maintained at a constant potential to enable reference electrodes to be dispensed with.  This is achieved, in the preferred embodiment, by a secondary redox system which senses the potential of the counter electrode by means of a conductor connecting the counter electrode and the electrode of the secondary system.          When the potential of the counter electrode falls below a given value, the secondary system, which is connected to the display electrolyte through an ion exchange membrane, charges the counter electrode with electrochromic material.          The counter electrode may be a grid.

Abstract: ROOF SUPPORT SYSTEM FOR A SUSPENDED STAGING                   Abstract of the Disclosure An outrigger beam projects outwardly beyond the edge of the roof, to serve as an overhead anchor for the suspension line of a suspended staging.  A support leg depends from the beam and makes contact with the roof inwardly of the roof edge.          At a location further inwardly from the roof edge, the outrigger beam is secured to an elevated support rail, but in a manner permitting both axial and sideways angular movement, as needed, for proper positioning of the outboard end of the outrigger beam relative to the side of the building.  The support rail counter-balances the weight of the staging.  The outrigger beam is connected to the support rail by a carriage which permits (1) the outrigger beam to be pivoted vertically about the support rail, for raising the support leg up off the roof, and (2) sideways movement of the tilted outrigger beam lengthwise of the rail.  A counterweight is provided at the inboard end of the outrigger beam to counterbalance the combined weight of the staging and the outboard portion of the outrigger beam.

In this process, rapid stirring is provided during the early part of the cooling period.  When the base stock has been cooled with relatively rapid agitation to a temperature below its cloud point, solvent is added to the base stock and mixed therewith and thereafter the mixture is cooled to the final or filtration temperature with essentially minimum agitation of the oil-solvent-wax mixture.  It is not necessary for the solvent to be at a temperature below the temperature of the base stock or that of the oil-solvent mixture.     -I-
