Inventor: SCHACHTER HERBERT IRWIN
IPC: H05K3/46
Filed: 1981-04-06
Abstract: A multi-level printed circuit board (30) with at least two levels of circuitry (32, 36). A substrate (30) has a first level of circuitry (32), an insulating covering or layer (34) over the entire surface of the substrate and the circuitry except in first predetermined areas, a second level of circuitry (36) is formed over said insulating covering or layer (34) and metallurgically bonded to form electrically conductive joints at the predetermined uncovered areas with the first level of circuitry (32). 
     The method of making a multi-level printed circuit board comprises the steps of forming at least one level of circuitry (32) on at least one side of a substrate (30), applying an insulting covering or layer (34) over the entire surface of the substrate and circuitry except in a first number of predetermined areas, forming a thin adherent conductive coating (36) over all exposed surfaces, applying a temporary mask (38) over the conductive coating (36) except in second predetermined areas which define the second level of circuitry on the side of said substrate, forming copper circuitry in said second predetermined areas, and removing the temporary mask (38) and said adherent conductive coating. The formation of the second level of circuitry (36) is repeated for as many levels as is desired, and levels of circuitry may be formed on both sides of the substrate (30). A final level of circuitry is formed and is covered by a final insulating coating except in final predetermined areas.

Abstract: Individual gas generator-turbine fan inflation units (33, 36) are mounted on a wall of each of the inflatable systems (18, 19) of a foldable inflatable article such as an escape slide (10). The article is foldable into a compact package for storage in a limited space. Each of the inflation units (33, 36) is mounted directly on a wall of each of the inflatable systems and may be packed with the wall. A lanyard (67, 86) for each of the inflation units extends out of the folded package to an elevated support (12) for actuation of the units by gravity trip upon opening and dropping of the article from the elevated support so as to provide substantially simultaneous inflation of all inflatable systems.

Bei niedrigen Fernspeiseströmen und hoher Fernspeisespannung werden die einzelnen Teile (E1, TR1, SV1, E2, TR2, SV2) jedes Regenerators hinsichtlich des Fernspeisestroms in Reihe geschaltet, wobei die Speisespannung des gesamten Regenerators und die der einzelnen Teile durch Zenerdioden (D10, D11, D12, D20, D21, D22) stabilisiert wird. Die bei der Stabilisierung auftretenden Schwierigkeiten können mit einer erfindungsgemässen Sendeverstärkerschaltung (SV1, SV2) überwunden werden, da diese keine mittels Zenerdioden stabilisierte Speisespannung benötigt.

Abstract: The method and apparatus for filling a flask (1) with a moulding material, in particular a casting moulding material, from a container (3) arranged underneath the said flask use pressure applied by a membrane (27) arranged in the container. By means of a nozzle lip (43) arranged on the upper edge of the container, the flask fitted tightly onto the container and sealed off air-tightly by a pattern plate (5) is first of all evacuated in order to avoid air being trapped in the compressed moulding material. After compression, the membrane (27) can be withdrawn by applying negative pressure. The container, which can be moved back and forth between a filling station and the moulding station, can be combined with a wiper for wiping off excess moulding material from the underside of the flask as well as a slide for closing the supply container into the moulding material. <IMAGE>

Abstract: Les maladies sont dues aux etats de non fonctionnement des mecanismes moleculaires dans les tissus. Il existe des electrons fonctionnels dans les mecanismes moleculaires qui tournent en avant et en arriere angulairement, selon un arc de 45 degres en fonctionnement normal. Lorsque ces electrons tournent de plus de 45 , ils continuent de tourner vers 90 et 180 . A cause de l'inter-relation de fonctionnement entre les molecules, les molecules adjacentes cessent egalement de fonctionner, peu a peu et perdent leur rejection magnetique normale aux molecules etrangeres, et la croissance commence par invasion, comme pour le cancer. Ces electrons depolarises ne peuvent reprendre leurs orientations polaires normales, et par consequent, un controle polaire artificiel est necessaire. Ces mecanismes, cependant, ont une organisation matricielle tridimensionnelle dans les tissus, et l'invention consiste a envoyer une radiation de champ magnetique qui tourne dans le tissu dans au moins trois plans perpendiculaires entre eux, pour normaliser les electrons depolarises, pour la guerison du cancer.

Abstract: Data is read from a magnetic record on a stripe on a card which is manually passed through a card-reading device at an uneven low velocity. The data is converted into unidirectional pulses in a demodulator (320), the amplitude of whose output varies in proportion to the relative velocity. The demodulator output is regenerated in a regenerator (330) and applied to a data storage register (340). The demodulator output is also applied to a filter (370) whose output is a potential proportional to the amplitude of the demodulator output. The filter output is applied to a voltage controlled oscillator (372) to produce a pulse train at a repetition rate proportional to the relative velocity, and to a read/write latch (360) to set the latch to gate the VCO output to the storage register to operate the latter to store data received from the regenerator bit-by-bit during a read part cycle of operation. The latch (360) is reset to connect a source (356) of constant repetition rate pulses to the register (340) to enable the latter to read out the data during a write part cycle for delivery to a date processing unit.

Abstract: A saw-chain sharpening device is provided which is releasably attachable to a portable chain saw to enable routing-type saw chain cutters (43) to be sharpened in situ on the chain-saw guide bar (2). The sharpening device comprises a support bridge (4) clampable to the saw guide bar (2) in a position straddling one pass of the chain (3). This bridge (4) supports a grinding-wheel mounting arrangement (11-15) which can be set up to orientate a grinding wheel (16) carried thereby into the plane of the routing-edge face of a cutter (43) to be sharpened. Once correctly orientated, the grinding wheel (16) is driven in rotation by external means (such as a conventional electric drill (19)) and approached towards the cutter (43) along a path lying in said plane. This path is defined by a linear guide (13) of the mounting arrangement, the guide (13) being slanted at the undercut angle of the cutter face.

Abstract: A micro-computer based clutch control system for an engine driven vehicle, includes a throttle pedal position transducer (18) and an engine speed transducer (SP1). The micro-computer (17), receives signals from these transducers and controls a stepper motor (13) which varies the clutch (10) engagement. The micro-computer (17) operates by generating a clutch engagement signal determined principally by the throttle position, such signal increasing as the throttle is opened initially and then decreasing as the throttle is opened further. The clutch engagement signal is corrected by adding a speed correction signal which is zero over a predetermined speed range, negative at lower speeds and positive at higher speeds.
