Abstract: FLUE GAS REHEAT SYSTEM            Abstract of the Disclosure An apparatus for reheating stack gases leaving a plurality of scrubbers which uses water within an associated steam generator as the heating source.  A heat exchanger receives heat from the boiler water transferring it to a low pressure fluid which is circulated through heat exchange surfaces downstream of each of the scrubbers.  The flow of the high pressure boiler water is controlled in response to a temperature of the low pres-sure fluid thereby providing a means for minimizing the flow and return temperature of the high pressure water.  The high pressure water is taken from a circulating pump discharge and returned to the circulating pump suction.

Abstract: Abstract of the Disclosure A  method and system for the quantitative description of human abnormal brain states, for example, to distinguish cerebral death from a barbiturate induced deep coma, includes an electroencephalograph (EEG) system utilizing scalp electrodes and amplifiers.  A computer based system controls a multimodal stipulator (clicks, flashes, etc.) to provide evoked response data for different sensory systems.  The ongoing EEG and averaged response data are processed quantitatively and compared with previously stored normative data, describing brain states in patients free of head trauma, to calculate a set of ?-transforma-tions.  The ?-transformations define ?, the brain state vector (BSV), which may be visually displayed.  The length, direction and change of BSV over time provide an evaluation of the ana-tomical location of any damage, the severity of functional impairment and the rate of improvement or deterioration of the patient's state in order to aid in selection and guidance of treatment.

Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus cleans footwear with a closed system utilizing brushes and with recirculating compressed air.  The apparatus has a housing and a cover containing a grill mounted to the housing by springs.  Beneath the grill are a pair of cy-lindrical brushes which are rotated by electric motors in a direction toward the center of the grill. A combined vacuum cleaner and air compressor beneath the grill provides both a source of compressed air to help clean the shoes and suction to collect the dirt and any other debris dislodged by the appa-ratus.  The brushes clean the bottoms of the shoes and direct any dislodged dirt and other debris toward the center area of the grill.  A pair of air tubes disposed along the edges of the grill direct the compressed air over the shoes and toward the center of the grill, along with any debris dislodged thereby.  Beneath the center of the grill is a removable collection tank having a slot facing the grill and having an open end connected by a filter to the intake of the air compressor.  The air compressor draws air into the tank through the slot and draws any debris in the collection area into the tank.  The debris is removed from the air by the filter and the filtered air is then re-compressed and recirculated via the air tubes over the top of the shoes.

Title: Surge voltage arrester with fail-safe  feature
Inventor: BAUMBACH BERTRAM W
IPC: H01C7/12
Filed: 1980-02-19
Granted: 1982-12-14
Abstract: Baumbach Case 282 Abstract of the Disclosure A surge voltage arrester utilizes for surge protection a varistor (16) of the zinc oxide type between a line terminal (4, 40) and a ground terminal (6, 60).  The varistor is of a type that has a resistance which de-creases as increasing voltage is applied thereacross. With increasing temperature the leakage current through the varistor increases at a given voltage.  At a critical temperature and voltage condition, the varistor is subject to a thermal runaway condition which would cause the varistor to fail expelling hot particles.  To avoid this failure condition, a fail-safe mechanism (34, 26, 30, 14 etc.) is provided which connects the line terminal to the ground terminal by-passing the varistor when there is an overcurrent condition on the line that results in heating of the varistor.

Abstract: ABSTRACT OF THE DISCLOSURE A two-piece rivet assembly comprising a shank member and a collar. The shank member includes a head, a cylindrical shank, and a helical thread with a substantially constant pitch, but with a crest diameter which decreases as it extends away from a maximum adjacent to its end farthest from the shank. The ring-like collar has an inner wall, an outer wall, and a first and a sec-ond end.  The inner wall defines a passage between the ends to receive at least a portion of the thread.  With the shank placed in an aperture in a workpiece with at least a portion of the thread projecting beyond a surface of the work-piece, the collar is placed over the thread and a swaging setting force is applied.  This force applies both axial and radial components to the collar. This forces the collar against a surface of the workpiece and swages the wall into the thread at its maximum diameter and then continuously along the thread, exerting a tensile force on the shank member.

Abstract: ABSTRACT OF THE DISCLOSURE            An entrainment cam, which is attached to an arm displacable in its lengthwise direction, is moved toward an open side of a printed product which is to be opened.  At the region of one corner of the product the entrainment cam engages a part of the printed product and entrains the seized sheets during further movement thereof.  This results in a nowing-out or bulging of the entrained product sheets, so that the part of the printed product which is not engaged by the entrainment cam can be raised.  In the thus formed gap there is inserted a holder element which supports the part of the printed product not engaged by the entrainment cam and in this way retains the gap open.  Now the entrainment cam is moved back into its rest position where it does not have any effect upon the printed product.  The latter then is forwardly advanced, in a direction essentially parallel to the product fold, towards a separation element which engages into the gap and completely opens the printed product.

Abstract: ABSTRACT     The application describes a sensitive intrusion detection system having an RF excited antenna located within the area to be protected and a leaky coaxial cable extending around the perimeter.  The presence of an intruder alters the coupling between the antenna and the coaxial cable thereby changing the signal received by the cable.  The detection system is responsive to incremental changes in the in-phase and quadrature components of the received signal.  When these components are plotted against each other a cardioid-like curve is obtained in the .DELTA.I,.DELTA.Q plane.  By tracking both magnitude and angle of this curve as it is generated a sensitive detection mechanism is provided.  When the variations in magnitude and angle exceed a threshold an alarm is sounded.           To avoid the possibility of intruders using a particular path which gives a null angle response, a second cable adjacent to the first may also be employed.  A further embodiment illustrates the use of three cables together with a separate antenna which provides multiple independent sensing systems.

Abstract: ICE ANCHOR ABSTRACT OF THE DISCLOSURE     An ice anchor useful for towing icebergs and ice fragments is formed in the preferred embodiment of a T-shaped frame comprised of a transverse member or beam and a shank attached to it.  Hot water is passed through narrow tubes around at least the bottom and sides of beam, causing the ice around it to melt.  The entire anchor sinks beam first into the ice. Torque is then applied to the shank, causing the beam to melt its way in a transverse path around the axis of the shank, after which the hot water is shut off, stopping the melting.  Towing tension can be applied to the top of the shank, and the resulting pressure is transmitted via the beam to unmelted ice directly above the beam, which is stressed in compression, the strongest failure mode of ice.  Collection and recycling of the water reuses the unexpended heat energy, resulting in high efficiency.
