Abstract: A gas laser has an electrode of improved construction. The electrode, for example a cathode, comprises an inner cathode (20) and at least an outer cathode (21) spaced from the inner cathode (20) and disposed on the side closer to an anode (12). Each of the cathodes (20, 21) has a central hole (24) from which a glow discharge (31) is formed, and the outer cathode (21) further has a plurality of through-holes (25) around the central hole (24). A gas medium (10) flowing in a discharge tube (2) passes through the central hole (24) of the inner cathode (20) via the central hole (24) and through-holes (25) of the outer cathode (21). The gas medium (10) forcedly enters the glow discharge (31) from the inner cathode (20) thereby to cause it to expand and a part of the gas medium having passed through the through-holes (25) of the outer cathode (21) squeezes the glow discharge (31B) from the outer cathode (21) so that the glow discharge (31 B) can enter the glow discharge (31A) from the inner cathode (20). Therefore, the current density of the glow discharge (31) in the discharge tube (2) is made uniform.

Abstract: A method and system for precipitating vapours from a continuous coater and retrieving suspended matter therefrom. The entrance and exit passages communicating with a spray coating booth are vented to a scrubbing chamber where a precipitant spray drives the vapours through a precipitant baffle. Suspended matter in the vapour is thus precipitated and drained into a recovery tank. The scrubbed vapours are then exhausted up a stack. In one embodiment of the invention, the vapours are vented through openings in the top of the entrance and exit passages, in which embodiment there is also provided an input chamber for receiving the vapours and transferring the same to the scrubbing chamber. In a second embodiment, the vapours are vented through openings in the side walls of the entrance and exit passages, in which case they are vented directly to the scrubbing chamber. In both embodiments, the precipitant spray is directly against the precipitant baffle resulting in the precipitation of large particles, such that there is no requirement for the provision of a plenum chamber or settling area. Additionally, the precipitation baffle is kept clean by the constant spray.

Abstract: A high pressure gas stream having a hydrogen content of up to about 90 mol percent is passed to a separator containing a permeable membrane capable of selectively permeating hydrogen. The separator is used to achieve a bulk separation of the desired hydrogen from impurities contained in the gas stream. The separated hydrogen is recovered at a reduced pressure and is passed to a pressure swing adsorption system adapted for operation at said reduced pressure. The off-gas from the separator is recovered essentially at the higher pressure of the gas stream. A portion of the off-gas is throttled to a lower pressure, with appropriate power recovery, and is passed to the pressure swing adsorption system as a co-feed gas, thereby contributing to the recovery of purified hydrogen product and to a reduction in the operating costs for the desired hydrogen separation and purification. The remaining off-gas is recovered as a relatively high pressure fuel or feed gas for other purposes.

IPC: H04L12/28

Abstract: There is disclosed an improved modem (78) for a single frequency, modulated RF carrier local data network for a distributed data processing system (Figure 4) and a method (Figure 7A and B) for line (64) acquisition and contention resolution. The protocol established for line acquisition and contention resolution is implemented by a modem controller (104). The controller (104) causes the receiver section (82) to listen for foreign carriers to determine when the line is busy. When the client device (66,70,72,74,68) of the modem (78) desires to send a data packet to another unit, the modem controller (104) causes the receiver (82) to listen for a certain pre-burst period and then causes the transmitter to send a burst of RF carrier out on the line and simultaneously causes the receiver (82) to listen to the line for interference beating i.e. changes in amplitude on the line which indicates another unit is requesting the line. To insure beat patterns, the frequency of the burst carrier is swept over a range during the burst. If a contention is found, a resolution thereof is made utilizing a random delay and retry protocol. 
     After the burst, the controller causes the receiver (82) to listen to the line for other carriers. If none are found, the controller (104) causes the transmitter (78) to transmit a data packet preceded by a preamble (115) of 100% modulation level RF carrier. During the preamble period, all receivers (82) in the system set their respective automatic gain control levels to a level for comfortable reception. The gain level so established depends upon the strength of the received signal. This amplification level is maintained throughout the entire data packet. 
     There is also disclosed herein a data link controller (530) and an interface specification for a generic class of network interface modems (78), one of which is disclosed herein for a client data processing unit for use in a data communications network. The specific modem (78) described herein is for use in a broadband local area data network with collision avoidance protocol. The data link controller (530) features hardware acknowledge circuitry (Figure 19) that acknowledges the receipt of a perfect data packet immediately upon receipt thereof without request to or assistance by the client data processing unit. The DLC (530) prepares the acknowledgment packet from the incoming data packet and places it on the data link without going through a line acquisition protocol. Each received acknowledgment packet is placed in a transmit buffer (571) at a known location relative to the data packet which was just transmitted, for which it is an acknowledgment so that each acknowledgment packet may be located in less time by the client data processing unit. The acknowledgment packets are logically part of the transmit process and are therefore placed in the transmit buffer.

Abstract: The present invention provides a completely self-contained intraoral larynx comprising a power source, tongue activated controls, power saving signal generation circuitry, acoustic and audio amplifiers, and an intra-oral speaker. These components are contained within an otherwise conventional denture or dental prosthesis. The device produces a high amplitude sound while minimizing current drain from the power source. Laryngectomized patients require only short term training by a speech pathologist to use this device. Intelligible speech is usual within an hour of such training, and facility rapidly improves. The psychological barriers, post-operative physical limitations, aesthetic concerns and limited gestural communication traditionally associated with the use of extra-oral larynges is eliminated by the present invention.

Abstract: The upper arm of a sewing machine according to the invention has its main shaft (16) carrying the crank disk extended perpendicularly to the zig-zag movement and positioned at the end of the arm. The problem in this positioning of the main shaft has been to develop a simple drive arrangement of the needle bar (15) so that the guiding means (12) of the zig-zag movement is not influenced by the needle bar propulsion. This invention has minimized the stressing of the zig-zag guiding means emanating from the needle bar propulsion. This allows the use of guiding means with a considerably less keeping force.

Title: Control of a fractional distillation process
Inventor: JAIN GYAN PARKASH
IPC: B01D3/42
Filed: 1984-08-07
Abstract: @ in a fractional distillation process in which it is desired to maintain a desired ASTM end point temperature of the overhead liquid product withdrawn from the fractional distillation process, changes in the heat removed by the fractional distillation process per unit of the feed are utilized to determine the equilibrium flash vaporization initial point and the equilibrium flash vaporization end point temperature for the overhead liquid product. The initial point temperature and end point temperature are then utilized to determine the actual slope of the equilibrium flash vaporization boiling point line. Changes in the slope of the equilibrium flash vaporization boiling point line are utilized to determine the actual slope of the ASTM boiling point curve at any particular time. The actual ASTM end point temperature for the overhead liquid product is derived based on the actual slope of the ASTM boiling point curve thus determined. The actual ASTM end point temperature is utilized to control the fractional distillation process so as to maintain a desired ASTM end point temperature for the overhead liquid product withdrawn from the fractional distillation process.

Abstract: A process is described for identifying those pels in a gray scale image which are candidates for vertical filtering before the image is thresholded to binary or black/white pel values. The vertical neighbor pels of a pel below a run end point are examined to determine whether their gray scale values fall within the same range. If they do, the horizontal neighbors of the current pel are examined to see whether their gray scale values fall in different ranges. If they do, the pel is vertically filtered by adjusting its gray scale value as a function of the differences between its value and the values of its vertical neighbors. Because only selected pels are vertically filtered, the process can be carried out with a general purpose microprocessor rather than a special purpose parallel processor.
