Abstract: CONTAMINATION REMOVAL SYSTEM AND METHOD                 ABSTRACT OF THE DISCLOSURE     A system and method for removing contamidated fluid from the ground in which water is pumped through a perforated pipe system into the ground to be decontaminated.  The water and the contaminants are then drawn into a removal pipe system and to a treatment unit for separating the con-taminants from the water before the latter is returned to the first perforated pipe system. According to an alter-native embodiment the water is drawn into the removal pipe system by producing a high velocity stream of water using a venturi device and passing the stream over the upper end of the removal conduit.  The vacuum created by the high velo-city stream causes the water to flow into the removal con-duit system.

Abstract: ABSTRACT      An inertial barrier system can be constructed with barrier units of various, sequentially increasing barrier weights (i.e., masses).  The inertial barrier units are each constructed from similar parts, namely, a frangible hollow container of conical or other generally circular cross section having upper and lower portions, with the lower portion having joined to the upper portion by substantially annular horizontal ledge; an inner core of frangible material and formed substantially as a hollow conic member, the flange being dimensioned to fit onto and be supported by the ledge of the container; and a frangible cover to fit the open top of the contain-er.  The inner core is orientable in either an upwards position or a downwards position, each of which has the flange of the core resting on the ledge of the container A unique feature of the inner core is that only a single core is needed for the various option of granular mater-ial; by contrast, conventional systems require separate cores for each of generally five options, namely, 200, 400, 700, 1400 and 2100 pounds of granular material.          The container is divided thereby into a lower section and upper section, with the upper section receiving a fill of energy-absorbing granular material, such as sand.  Indicia embossed on the core and on the inside of the container indicate the various predetermined levels to which the container is to be filled to provide a barrier unit of the proper predetermined weight.

Title: Beverage making device
Inventor: ROBERTS MELVIN F
IPC: A47J31/56

Granted: 1988-08-30
Abstract: An improved beverage-making device, particularly useful for brewing coffee, provides a safety thermostat arrangement for quickly detecting excessive temperatures of a hot water container generally near a heating element arranged therein. A running thermostat provides a self-supporting sensing tube means in cooperation with a capillary tube and thermostat which detect the mean temperature of the hot water and are responsive to a narrow range of temperature variations within the hot water container. The improvement further includes a tap-off hot water system which provides hot water separately and independently of the brewing water heated in said container. The system is connected upstream of the cold water inlet valve of the device and directs cold water into a water coil means residing within the hot water container. Outlet pipe means convey heated water from the coil to an outlet faucet projecting exteriorly of the device. An improved spray disk assembly provides a cooperatively lockable spray disk and mounting collar. The spray disk locks with the mounting collar to tightly seal a flexible gasket around said spray disk whereby the spray disk receives hot water siphoned from said hot water container and evenly distributes hot water in a random dripping flow through the, disk. Additionally, a bottom drain system is provided for emptying the hot water container which is noncorrodible and thread disengageable from said container. The drain system provides means for tightly sealing around a bottom drain hole of the container and manually operable valve means to facilitate draining the container. 31

Abstract: INVENTION:  LIM SECONDARY REACTANCE             COMPENSATION AND THRUST CONTROL                     INVENTOR:   W. JOHN BALLANTYNE              ABSTRACT OF THE DISCLOSURE         In a transportation system involving a track side linear induction motor (LIM) primary and a vehicle carrying a LIM secondary, an arrange-ment is provided for selectively altering the thrust characteristics of the LIM secondary in operation.          The LIM secondary has a three-phase reaction winding rather than a conventional reaction plate.      Each of the individual phase windings has a controlled variable resistance parallel connected with a capacitor across its ends.  The capacitors compensate for energy normally stored in the air gap between the primary and secondary, and provide improved thrust characteristics during high slip operation.  The resistances can be controlled from within the vehicle thereby providing a form of on-board thrust control which can in large measure replace the more standard voltage control which is normally provided at each LIM primary on the track.

Abstract: Abstract ACTIVE COOLING SYSTEM FOR ELECTROCHEMICAL CELLS     An  active  cooling  system  (40,  41)  for  cooling electrochemical  cells  (11)  that  are  arranged  in  a stack (9) in a fuel cell or battery (3).  The cooling system  (40,  41)  comprises  cooling  panels  (15, 16) carrying a cooling fluid That flows adjacent to, and parallel to the plane of, each cell (11).  The rate of cooling fluid flow past each cell  (11) is made to be substantially   equal,   so   that   each   cell   (11) experiences    substantially    the    same    cooling environment, adding to the longevity of the fuel cell or  battery   (3).    This   can  be  accomplished  by equalizing the resistance  to  cooling fluid  flow for each  cooling  path  (12),  e.g.,  by  using  pressure equalizing, monotonically increasingly sized orifices (28)  in an input manifold (25).  Dual cooling panels (15,  16)  are  preferably  employed,  in  a  counterflow mode.   The  panels  (15,  16)  may  be  divided  into parallel  channels   (33).    Heat  pipe  panels   (35) containing a two-phase fluid may be used in lieu of panels (15, 16) that contain cooling fluid in a single state.

Abstract: ABSTRACT OF THE DISCLOSURE       An OR logic function is provided in at least two separate circuit branches by diodes in parallel summing current at a first logic node and a first circuit branch and diodes in parallel summing current at a second logic node in a second current branch.          An AND logic function is performed at a third logic node by using additional diodes connected in parallel at the third logic node so as to share current passing through the third logic node, with the logic conditions at the first and second logic nodes serving as the inputs to the AND logic function.  The logic condition at the third logic node is applied to the gate of a switching FET.  The switching FET is conveniently employed to invert the logic condition at the third logic node.  The invention is particularly suited for use with MESFET logic families using gallium arsenide (GaAs) substrates.

Abstract: Abstract of the Disclosure An improved servo control system for data track following of the read/write head in a magnetic recording system uses a pattern of segments of servo information slanted across the data tracks.  The time of flight of the servo segment from occurrence of a reference pulse until the peak servo signal is read by the head is an indication of the position of the head in a direction perpendicular to the desired track.  This time is compared with the known time of flight if the head were precisely over the centerline of the desired track and the time difference is used to generate a control signal to position the head over the track centerline.   In an embodiment where each segment is slanted across only one track, the reference pulse is the beginning of the servo signal and the time measurement is the number of fixed frequency magnetic transitions read by the head in the servo segment.  When the system is used in flexible disk drives, the servo segments are written in one of the data sectors on the flexible disk by the user's disk drive.
