Abstract: ANTI-STATIC TRAY FOR SEMI-CONDUCTOR DEVICES AND COMPONENTS      Abstract of the Disclosure An anti-static tray for holding semi-conductor devices and components, is formed by a flat sheet of metal, for example aluminum with a layer of electrically conducting foam material on one side. Terminal pins extending from the devices are pushed into the foam, and securely held.  The devices are then protected from static charges which might be applied by persons removing devices as any static charge is bled off into the metal sheet.  Legs can be formed by bending down short lengths of metal from the sheet, so that trays can be stacked without contact between a tray and devices and components mounted on the tray beneath.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus in which lateral movement of a moving belt is controlled so that the belt moves in a predetermined path. The apparatus includes at least one rotatably mounted roller comprising a flexible outer sleeve having at least one spiral slot extending around the periphery thereof. The sleeve has a plurality of spaced grooves extending in a direction substantially parallel to the longitudinal axis of the roller. In this way, the flexible outer sleeve is divided into segments with each segment being decoupled from one another. Preventing the belt from deviating laterally from the pre-determined path deflects the segments supporting the belt. The deflected segments return to the undeflected condition when not supporting the belt insuring that the maximum force applied on the belt never exceeds the minimum force required to buckle the belt. A roller of this type prevents the formation of a pattern of permanent corrugations in the belt.

Each pocket contains a protective element which overlaps adjacent elements whereby the garment is rein-forced over the whole of the length of the garment.         Because the protective elements are supported independently of each other, they are movable relative to each other both laterally and transversely.         Thus the garment can flex to follow the contour and spinal movement of the person wearing the garment.

Abstract: BEVERAGE MAKING MACHINE  WITH HOT WATER FAUCET          Kenneth W. Stover Abstract of the Disclosure A beverage making appliance operable automat-ically or manually, and also providing a faucet which allows removal of a variable quantity of hot water from a hot water tank.  The appliance has a cold water basin located over a hot water tank with a cold water tube ex-tending down into the hot water tank from a drain opening in the bottom of the basin whereby cold water discharges by gravity from the basin directly into the lower portion of the hot water tank and displaces an equal quantity of hot water either through a faucet, or through a siphon tube for discharge through a spray head onto the contents of a brew funnel positioned beneath the spray head.  When the appli-ance is operated in its automatic mode to make coffee or other beverage, cold water is delivered to the cold water basin through a cold water conduit connected with a supply of cold water under pressure.  The cold water supply con-duit is provided with both a flow control valve and a solenoid valve whereby predetermined volumes of cold water may be repetitively delivered to the appliance on each actuation of a timer.  The appliance also has a tube ex-tending from the hot water tank to a faucet on the ex-terior of the unit through which hot water may be drawn for brewing single servings of instant coffee, hot tea, and similar instant hot beverages.  A level control circuit, together with a water level sensing probe disposed within the hot water tank, also actuates the solenoid valve so as to maintain a predetermined water level in the tank as hot water is drawn through the faucet.  Additional circuitry, including a relay, disables the level control circuit on actuation of the timer when the appliance is operated in its automatic mode.  The relay, through a set of normally closed contacts, electrically connects the level control circuitry with the solenoid valve.  The timer is connected to the solenoid valve through a second set of normally open contacts of the relay, and when the appliance is operated in the automatic mode, the relay disconnects the level control circuitry, allowing the timer to control the solenoid valve.

Abstract: ABSTRACT         Methods and apparatus are described utilizing low frequency tube waves in determining characteristics of formations traversed by a borehole.  Data received from three spaced receiving transducers are utilized in formulating quantities representative of complex compressibility of formations as well as loss parameters attributed to formation characteristics. When these two factors are recorded as a function of depth, interpretation is made readily available as to the permeability and rigidity of subsurface earth formations.  Data is also provided by way of the present invention to enable interpretation concerning the presence of fractures or cracks in the earth formations.  The methods and apparatus may also be utilized to examine the condition of casing in a borehole.

Abstract: Abstract An apparatus for the movement of articles in a predetermined upright position from a first station to a second station, spaced from the first station, by a foraminous transfer belt.  A vacuum plenum has a wall against the back side of the transfer belt with spaced longitudinal slots therein so that maximum vacuum is drawn in the plenum through jet openings in the belt which is sufficient to just lift and support properly oriented articles from the first station and transfer them to the second station. The transfer belt can be run at a higher speed than that with which articles are supplied to the first station to space articles longitudinally along the transfer belt.     The second station includes a conveyor with converging side walls for moving the separated containers into single file arrangement over a much shorter longitudinal distance than would otherwise be possible.

Abstract: FOR: SYSTEM FOR THE PRINTING & READING      OF ENCRYPTED MESSAGES     ABSTRACT OF THE DISCLOSURE                      A system for the metering of encrypted post-age and similar indicia includes a device for printing such indicia and a device for reading such indicia.          The printing is accomplished with a dot matrix printer driven by signals obtained by altering character gen-eration signals with encryption signals.   The inter-leaving is accomplished on a row-by-row basis by in-serting delays from an encryption circuit into signals from a character generator circuit.   The reading is accomplished by correlating received characters against a stored array of symbols to determine the presence of a symbol, the extraction of coded data from character data of the received and identified character, and the comparison of the separated coded data with a reference code to determine the accuracy of the printed material.          Thereby, forgery and alteration is inhibited.  The cod-ing is accomplished with the dot matrix format of the characters by displacing some of the dots slightly from the remainder so as to retain the general form of the character for recognition of the character while the displaced dots serve as the code for the encryption.

A rotating biological contactor is provided in each section for increasing the liquid/gas interface to facilitate the anaerobic reaction.  A series of partitions is provided in each section to create zones in which the waste concentration is extremely high and on which the biota can react at maximal reaction rates.  The CO2 produced in the acid forming phase is used in both acid and gas forming sections to mix and achieve pH adjustment, and the methane can be used in the gas forming sections for mixing.  A thermophilic chamber in the center of the tank is surrounded by the mesophilic chamber to minimize and utilize conductive heat loss.
