Title: Deep-fat fryer
Inventor: SCHWIZER ANTON
IPC: A47J37/12
Filed: 1984-12-11
Granted: 1987-05-12
Abstract: Abstract of the Disclosure The deep-fat fryer has an upper basket (41), a heat-ing source (8) below and a heat exchanger in between (13) for the exchange of heat between a gaseous heat exchange medium (57) and the frying oil (55).  Thereby thermo-siphonic oil circulation results.  A blower (29, 31, 32, 33) is arranged, whereof a blower rotor (31) imparts a higher velocity of flow to the heat exchange medium (57) in the heat exchanger (13).  The blower (29, 31 through 33) is arranged in the fresh air supply duct (56), in the gas vent (57) and in the cool air supply duct (58) for cool-ing the flue gases.  The three blower wheels (31 through 33) are arranged on one and the same drive shaft (30).          This deep-fat fryer takes significantly better advantage of the heat conducted to it.  With large energy densities relative to the oil volume, it has minimal specific heat-ing surface loadings and thereby affords optimal relation-ships.

Abstract: ABSTRACT OF THE INVENTION           A high speed and relatively error free communications system is disclosed which enables the high speed transmission of data at a 19.2 kilobit per second rate.  The data is transmit-ted over the same communications medium as voice transmissions, the data transmission being virtually imperceptible to the user of the analog telephone system.  Connection to and from the data terminals is made through an RS232C interface.  A spread spectrum technique is utilized which "whitens" the signals of the data terminal regardless of whether the terminal is idle, transmitting or receiving data. Virtual error free transmission is achieved by interleaving bits, so that noise does not destroy the data, and by error detection and correction techniques which assure that the data, as received, is identical to that transmit-ted.  By using a variable pseudo random code, privacy of data communications are enhanced and cross-talk is substantially eliminated.  The resulting system is one that can use a single twisted pair wire for transmission and is capable of transmitting data at a high rate of speed while leaving the analog voice transmission resident and unaffected on the line.

Abstract: ABSTRACT OF THE DISCLOSURE            A PLATE WITH A DECORATIVE PATTERN AND A METHOD AND AN          APPARATUS FOR PRODUCING THE SAME    In order to produce a decorative pattern on the surface of a layer of material in a soft plastic condition, the surface is whipped by the free end portions of a plurality of flexible thread-like members. The whipping action provides random depressions in the surface. The thread-like members are preferably fastened to the peripheral surface of a rotatable body which is spaced from the surface to be treated at a distance which is substantially smaller than the length of the thread-like members, and the surface to be treated is moved in rela-tion to the rotatable body while this body is rotated. By this whip-ping action it is possible to make surface patterns imitating a slaty surface or the surface of other natural materials. Such decorative surfaces may be made on layers of materials which are cut into plates or blocks for use as building materials after firing, setting or harden-ing of the material. As an example, the decorative pattern or struc-ture may be made on plates to be used as roofing plates.

Abstract: INTERRUPT LEVEL SHARING                         ABSTRACT   An  interrupt  interface  circuit  for  interrupt level sharing comprising a pulse generator having an open-collector or  tri-state  output connected  to  an external interrupt line shared by other similar cir-cuits.  An active internal interrupt signal causes the pulse generator to pulse.  The external interrupt line is fed back and latched on a disabling input of the pulse  generator  so  that  any pulse  on the external interrupt line prevents further pulsing.  The software handler of the interrupt, upon servicing an interrupt of the interrupt level,  causes the enabling of the pulse  generators  of that  level,  thereby permitting active internal interrupt signals to produce a further pulse.   By  this interrupt  level  sharing,  phantom interrupts are eliminated and servicing overhead is mimimized.

Abstract: ABSTRACT     In a multi-tasking data processing system, each task may request that the operating system set up descriptor blocks which identify virtual screens for display of data on the video display.  Under keyboard control, only one virtual screen is selected for display at a given time.  The operating system reserves a portion of the video display for displaying identifiers of the virtual screens which have been established but which are held in background.  Each virtual screen may be subdivided into viewports by the corresponding application task.  Those viewports are also identified in the operating system by descriptor blocks which point to pages of data in the document files.  The descriptor blocks can be modified through requests from application tasks even when held in background.          Whenever the display memory is updated, data designated by the descriptor blocks is passed through a rasterizer in the operating system which generates the pixel data to be stored in a display memory.

Abstract: RIBBON FEED WITH INK DEPLETION COMPENSATION                  Abstract of the Disclosure Where the ribbon advance mechanism of a printer is driven by the motion of the print head carrier, ink in the ribbon will be differentially depleted depending upon the density of print.  This varied depletion becomes a problem for printers capable of printing high density graphics images, particularly color filled images.  In accordance with this invention, the printing density is monitored and when the printing density exceeds a predeter-mined value, the print head is caused to be moved an amount greater than that necessary to position the print head at a succeeding print position so as to thereby cause additional ink ribbon to be advanced and to avoid overprinting on areas of the ribbon where high density printing has occurred.

Abstract: ABSTRACT OF THE DISCLOSURE           Operation of similar electronic article surveillance (EAS) systems in proximity to each other may result in false alarms or system "shut-downs" as a result of signals transmitted from one system being detected in the receiver circuits of the other systems.  This may especially occur with EAS systems in which the receivers are only activated during quiescent intervals between transmitted bursts, such that if the systems are unsynchronized, the transmitted bursts of the one system may occur during the quiescent intervals of the other system.  In the present invention, synchronization is effected by responding to RF detected during the quiescent intervals and preventing the transmitted bursts from occurring during the quiescent intervals of the other system.

Abstract: ABSTRACT A suture anchor system that includes a drill for turning into a bone mass with sissoring blades pivotally connected in a longitudinal drill shaft slot proximate to a cutting end thereof, the blade ends to sissor to extend cutting edges outwardly therefrom, which sissoring occurs at a certain depth of penetration into the bone mass, cutting a flared or skirted hole therein, to receive a suture anchor whereto a suture is secured. The suture anchor consists of a suture rivet and slotted ring and is formed by moving the suture rivet into the slotted ring, that ring breaking at spaced apart slots formed therein and flaring into a skirt, the anchor rivet and slotted ring thereby locked together as the suture anchor, which suture anchor has approximately the same shape but a slightly lessor diameter than the hole formed in the bone mass. The suture rivet and slotted ring are mounted on an applicator for fitting into the bone mass hole, the applicator consisting of a grip and trigger pivotally coupled thereto, such that, with trigger movement towards that grip a plunger attached thereto will be moved also, which plunger is releasably secured to a head of a mandrel that is telescoped through an ejector that is for releasable mounting in the applicator, which mandrel slides in the ejector and connects on its distal end to the suture rivet. Plunger travel therefore, responsive to trigger depression, moves the mandrel to pull the suture anchor into the slotted ring and the mandrel thereafter separates from the suture anchor allowing the applicator to be removed from the seated suture anchor and expose the suture attached thereto.
