Title: Cover and support plate arrangement for wall mounted devices
Inventor: JACOBY ELLIOT G JR
IPC: H01H9/52
Filed: 1987-03-10
Granted: 1991-10-08
Abstract: COVER AND SUPPORT PLATE          ARRANGEMENT FOR WALL MOUNTED DEVICES       Abstract Of The Invention A cover and support plate arrangement for a wall mounted device, such as a wall switch, display, dimmer, etc., for mounting to a wall box embedded in the wall and having overall surface dimensions greater than that of the wall box.  The cover plate is juxtaposed over the front surface of the support plate and is spaced therefrom to provide an air gap between the cover plate and the support plate creating a chimney through which air currents may flow.  The device includes an electric circuit having a heat generating device, such as a triac, which is thermally connected to the support plate and in series electrically with a controlled load.  The cover plate casts a shadow along vertical sides of the support plate such that the vertical sides of the support plate are visible only when viewed at extreme angles with respect to an imaginary line perpendicular to the plane of the support plate or the wall in which the device is mounted.  The cover plate appears to float from the wall while proper thermal dissipation is achieved through the chimney between the cover and support plate.  Means are disclosed for con-structing a low profile, conventionally sized family of wall mounted dimmer switches that meet Underwriters Laboratories operating temperature standards.

Title: Method for transmitting data in packet switching networks
Inventor: SCOLES BRUCE D
IPC: H04J3/02
Filed: 1987-04-16
Granted: 1992-04-07
Abstract: ABSTRACT OF THE DISCLOSURE          A method for transmitting data in packet switching networks provides a Collision-Eliminating Multiple Access protocol in which nodes desiring to transmit over the network channel trans-mit reservation requests during a plurality of contention slots, the number of contention slots being dynamically controlled according to network load.  A node designated to next obtain con-trol of the channel receives the identifiers of nodes trans-mitting reservation requests and, prior to transmitting applica-tion data, transmits network control data consisting of the identifiers of nodes from whom successful reservation requests were successfully received.  The transmitted identifiers are re-ceived and stored by each node in an identical queue, whereby subsequent control of the channel is rotated based on the order of node identifiers appearing an identical queue on each node.     The transmitted network control data includes reservation re-quests received during a previous contention slot period, queue correction informtion, and the identifiers of nodes from which the controlling node expects to receive data.

Title: Method and apparatus for generating a character image
Inventor: DO PHUC K
IPC: G09G5/22
Filed: 1988-03-08
Granted: 1992-05-19
Abstract: ABSTRACT      This invention relates to a method for generating character images using a font compression algorithm that reduces the storage requirements associated with low-cost, high resolution printers.  An expanded character image has original print slices and duplicate print slices identical to one or more of the original print slices where the duplicate print slices are eliminated in the compressed character image.  The compressed character is expanded using a repetition mask that identifies the number and location of the duplicate print slices.  The technique for expanding the compressed character is such that printing can be performed in real time, in either a forward or reverse direction with only minimal effects on processing.  This invention also provides a means for supporting multiple pitches, such as 10 CPI, 12 CPI and Proportional Space Mode (PSM), within those storage constraints.  The technique of this invention is efficient enough to be performed by microcode in real time, yet provides for significant reduction in the overall memory required for storing the font data.

Abstract: A METHOD FOR TRANSMITTING DOWNHOLE                 DATA IN A REDUCED TIME     Abstract of the Disclosure A tool face orientation of a directional drill bit within a borehole is efficiently communicated to the well surface by communicating only changes in the tool face orientation.  In the first embodiment after the entire tool face orientation is measured and transmitted uphole, and thereafter changes of the tool face orientation as measured with respect to the center of spatially fixed sectorial ranges are transmitted uphole.  The magnitude of the changes relative to the center of a fixed sectorial range, being smaller than the range of the entire tool face orientation, allow the subsequent transmission to be made using words of shorter length.  Alternatively, the changes in tool face orientation may be measured with respect to a sliding reference point.  The sliding reference point may, for example, be the mean value of the prior ten measurements and any previous mean values.  The sliding sector will then be held until change in the tool face orientation cause the tool to go out of the sectorial range of the sliding reference point, at which point a new sliding reference is defined which inherently includes the tool face within its range.

Abstract: This invention relates to a digital sound data storing device in which analog signals are obtained from digital sound data.  The digital sound data storing device includes a case enclosing a reproduction unit and an IC card detachably attached to the case.  A plurality of digital sound data groups are stored at a built-in IC memory of the IC card.  The sound data groups are obtained, for example, by recording short sentences for practicing conversation of a foreign language, through a microphone to obtain analog sound signals and digitizing the analog sound signals.  When the IC card is attached to the case, a sound synthesis circuit enclosed in the case reads out the sound data groups and converts the digital sound data groups to analog signals, which are amplified to be reproduced as sound groups.  When any one of push buttons disposed on the case is depressed to input an identification code corresponding to any sound desired or not desired to be reproduced, data of the identification code is inputted in the built-in memory.  Based on the data of the identification code, the sound groups are selectively reproduced or selectively excluded from the sound groups to be reproduced.

Abstract: ABSTRACT      Wood chips, or like comminuted cellulosic fibrous material, are treated in a vertical presteaming vessel in the production of paper pulp. The vessel does not employ a vibrating discharge structure as is conventional, but rather utilizes as a discharge structure a plurality of rotating arms having depending blades, mounted at the bottom of the vessel, which force the wood chips toward a discharge opening in the vessel bottom.  The steam is introduced into the vessel through a vertical tube concentric with the vessel, and surrounding a rotatable shaft which is connected to the arms of the discharge device.  A truncated cone is provided at the bottom of the steam tube, making a slip connection with the tube, and overlies the discharge opening.  The cone has maximum horizontal dimensions greater than those of the outlet, to cause the chips to move radially outwardly into contact with the discharge element.  The vessel may be used in place of a chips bin in a conventional chips handling scheme, or may be utilized in place of a conventional horizontal screw steaming vessel.
