Title: Systems and methods for removing impurities from industrial oils and oil storage tanks
Inventor: KOREIS MONTE M
IPC: C10M175/00
Filed: 1994-10-26
Abstract: SYSTEMS AND METHODS FOR REMOVING IMPURITIES  FROM INDUSTRIAL OILS AND OIL STORAGE TANKS        ABSTRACT OF THE INVENTION      A system for reclaiming industrial oils having, in the following order, a prefilter, a pump, a particulate filter stage, a coalescer/separator stage, and an absorption stage. The pump causes oil to be reclaimed to flow through the system. The prefilter filters out solid particulates greater than a first predetermined size, the particulate filter stage filters out solid particulates greater than a second predetermined size, and the absorption stage filters out solid particulates greater than a third predetermined size. The first predetermined size is greater than the second predetermined size, while the second predetermined size is smaller than the third predetermined size. This arrangement prevents the coalescer/separator stage and the absorption stage from filtering out solid particulates, instead allowing these subsequent stages to be dedicated to the removal of unwanted fluids such as water from the oil passing through the system.

Title: Belt cooking apparatus
Inventor: ALDEN LORNE B
IPC: B65G23/44
Filed: 1994-11-22
Abstract: A belt grill is described herein for continuously cooking fast food products on a conveyor formed of counter-rotating heat conductive belts. The belts are heated by platens disposed above and below whereby a run of the belts passes in heat conductive relationship between the platens, and the food to be cooked is placed in the nip between the rotating belts. The device further includes means for tensioning the belts which can be automatically released by increasing the distance between the platens whereby when the distance exceeds a predetermined maximum, all tension on both belts will be released so that the belts can be quickly removed for cleaning or replacement. The belts are preferably Teflon coated fiberglass and may be disposed at an angle to the horizontal to facilitate grease removal from the cooking process.

Title: Restaurant type griddle with modular construction and which is load sensitive
Inventor: BRUNO ADRIAN A
IPC: H05B3/72
Filed: 1994-12-14
Abstract: A multi-zone restaurant type of griddle is modularly constructed so that all maintenance may be done at the front of the griddle housing.  The griddle plate is only three-eights  of  an  inch  thick with heat  being  spread uniformly by an aluminum plate in intimate contact with the bottom of the griddle plate.  A thermocouple temperature sensing element is located at the bottom of a hole in the underside of the griddle plate so that the element is very near  the  cooking  surface  and  is  sensitive  to  the temperature  of  the  load  on  the  cooking  surface,  as distinguished from being sensitive to the temperature of the heating element below the griddle plate.   With the modular construction, the front access, and light weight, all of the repairable parts of the griddle may be removed and replaced by one man as distinguished from most prior art griddles where two man service teams were routinely required because they had to lift and invert a very heavy griddle which had a very thick steel griddle plate.

Title: Method and apparatus for sorting particulate material according to the thermal properties of the particles
Inventor: LEVITT CHARLIE M
IPC: B07B13/00
Filed: 1995-02-17
Abstract: The invention concerns a method of sorting particles according to theirthermal properties. In the method, the particles (26, 28) are thermally treated in such a manner that particles of one type, typically diamonds, have a temperature which is below the freezing point of a liquid and lower than that of particles of a second type, typically rock particles associated with diamonds. The thermally treated particles (26, 28) are located on a perforated conveying surface and the conveying surface is caused to pass through a body of the liquid. The relevant parameters, such as time and temperature, are selected such that particles of the first type become firmly secured to the conveying surface as a result of a body of frozen liquid being created on those particles and extending on both sides of the conveying surface. Particles of the second class are not secured to the conveying surface in this manner. Thereafter, the different types of particles, which are respectively secured and unsecured to the conveying surface, are separately recovered from that surface.

Filed: 1995-03-16
Abstract: An accumulating apparatus for a sheet-like negative film holder fed from a feeding section. The film holder is capable of holding a plurality of negative film strips as arranged along the lengths thereof. The apparatus includes a retaining section for retaining the film holder in a suspended state and having a pair of retainer units disposed adjacent the feeding section and arranged one after another in a direction of transporting the film holder for retaining a rear end of the film holder respecting its transporting direction, and a retaining section driver unit for selectively driving the pair of retainer units to a retaining position or to a non-retaining position. When the retaining section is about to receive the film holder from the feeding section, the retaining section drive means drives only one of the retainer units to the non-retaining position. Whereas, when the retaining section has received the film holder, the retaining section drive means switches over the one retainer unit from the non-retaining position to the retaining position and also switches over the other retainer unit from the retaining position to the non-retaining position.

Title: System and method for cleaning the display screen of a touch screen device
Inventor: KEEN DONALD MARION
IPC: H04M1/247
Filed: 1995-05-11
Abstract: A procedure for cleaning a display screen in a touch screen based telephone such that features of the telephone are not inadvertently activated is described. The procedure operates by causing the telephone (actually, a processor in the telephone) to enter a "clean screen" mode in response to a request from the user to clean the display screen. While in the "clean screen" mode, all signals generated in response to the user touching the display screen are ignored. In this matter, while in the "clean screen" mode, the user is able to clean the display screen without inadvertentlyactivating any features of the telephone. The telephone automatically determines when the user has finished cleaning the display screen. When it is determined that the user has finished cleaning the display screen, the telephone leaves the "clean screen" mode and enters an "active screen". While in the "active screen" mode, all signals generated in response to the user touching the display screen are processed.

Title: Apparatus and method for randomly accessing sequential access storage
Inventor: TSUKAMOTO JUNICHI
IPC: G06F12/08
Filed: 1995-07-14
Abstract: An information storage device randomly accesses data items in a sequential access storage medium. A controller, upon loading of the sequential access storage medium, causes the blocks of data items in the sequential access storage medium to be copied to corresponding blocks on the random access storage medium whose correspondence is established by the table. A table establishes the correspondence between blocks of data items in the random access storage medium and blocks of data items in the sequential access storage medium. Upon receiving an instruction from a host computer, the controller further performs a series of read/write operations on the blocks of data items in the random access storage medium. The overwritten blocks of data items on the random access storage medium are updated to the corresponding blocks on the sequential access storage medium.
