Patent EP-0271859-A2 (EP)
Inventor: JOHNSON PIERCE JR
IPC: H01K1/18
Filed: 1987-12-14
Abstract: This invention provides an improved compact fine wire incandescent lamp filament and method for making the same. The filament has a primary mandrel ratio in the range of about 1.40 to about 3.00 and a secondary mandrel ratio which in the range of about 3.0 to about 10.0. 
     The improved filament design exhibits an increase in compactness and retains or increases structural rigidity while exhibiting minimal sag when the filament is incorporated into an incandescent lamp of the tungsten halogen type variety. 
     The compact coiling method is particularly useful in designing compact filaments for high voltage applications where it is desirable to eliminate the use of rectifying means to lower the effective voltage across the filament.

Abstract: A seat belt tightening device for removing slack in a seat belt (3) when the seat belt is required to positively restrain a user, comprising clamp members (l7; l8) for clamping a part of the seat belt paid out from a retractor device; a winding member (l8) for winding thereonto a portion of the seat belt that is located beyond the part clamped by the clamp means by a rotary motion; and a drive source (l6) for causing a rotational motion of the winding member. The winding member may be either integral with one of the clamp members or separate from both of them. Since the slack in the seat belt is removed simultaneously as the seat belt is clamped, the passenger is effectively restrained in case of a vehicle collision without being thrown forward due to any slack in the seat belt, and since the seat belt is allowed to pass through the tightening device without being obstructed under normal conditions the comfort of the passenger is assured by the action of a retractor which is typically provided in conjunction with the seat belt tightening device.

Abstract: A cardiac stimulator is provided for detecting and treating ventricular tachyarrhythmias of a patient's heart. The stimulator includes means for selectively dividing the heart rate continuum into regions including at least two classes of tachycardia (TACH-1, TACH-2, TACH-3), contiguous to each other and of progressively higher heart rate ranges, the lowest and highest of the tachycardia classes being bounded respectively by a sinus rate region (SINUS) and a fibrillation region (FIB) of the continuum. Means are provided for selectively adjusting the boundaries between the tachycardia classes and between the lowest and highest of those classes and the respective sinus rate and fibrillation regions, to correspondingly adjust the rate ranges of the classes in a desired manner. Cardiac events are selectively detected anywhere within the continuum and a distinction made between normal and abnormal tachycardias among the detected events. A detected abnormal tachycardia is then treated with any of a multiplicity of therapy regimens of differing degrees of aggressiveness, toward terminating the detected tachycardia.

Abstract: A method of preventing interference between 'friendly' pulse doppler radars when in action against a common target or adjacents targets. Despite considerable separation of the radar r.f's the pulsed signals have repeated sideband pulses which may be taken by another radar as a doppler-shifted echo. This problem is to a large extent alleviated by frequency modulating the r.f. transmission at a very low cycle rate of the order of one cycle per second and at a modulation rate sufficient to indicate to a receiving radar that the source could not be a target accelerating at such a high rate.

Abstract: A surface-mount-technology repair station and method for replacing components on SMT circuit boards. The station includes a base with a controllable heating element through which deionized air is blown onto the surface of a board opposite to the surface on which the repair is to be effected. This raises the temperature of the entire board substantially but to a point below the melting point of solder. A second heating element through which deionized air is blown is positioned over the leads of a selected component positioned on the board, that is either to be removed from or secured to the board. The heating of the leads by the second heating element causes the solder on these leads to melt, thus, enabling replacement of the component. To remove the component, the operator, using an instrument, such as tweezers, grasps the component and removes it from the board. To install a component, the operator, after melting solder on the leads, discontinues the heating of the component. 
     The method of the present invention includes the steps of heating the surface-mount-technology boards to a substantially high temperature, and then heating the leads of a selected component to be replaced so that the solder disposed on the leads melts.

Abstract: On a balancing machine, which has a shaft on which the wheel, mounted on the said shaft, can be driven in rotation, electric transmitters coupled to the shaft, which emit transmitter output signals when forces act on the wheel, and a computer which determines the unbalance data from the transmitter output signals in conjunction with wheel-specific data, the stationary wheel is made to oscillate and the wheel-specific data are determined from the transmitter output signals which are emitted by the transmitters during this procedure. To do this, the transmitter output signals are compared to the specimen signals which are stored for each specific type of wheel together with associated wheel-specific data. If the transmitter output signals and the specific signals correspond, the associated wheel-specific data are made available for the determination of the unbalance data. The transmitter output signals while the wheel is being driven are converted into an unbalance frequency spectrum and the unbalance data are determined from the unbalance frequency spectrum. …<IMAGE>…

Abstract: An apparatus for manufacturing a heat-shrinkable tube has a die formed with a center bore through which a resin tube passes and a plurality of radial holes extending from the bore to the outer periphery of the die. The die is contained in a tank filled with a cooling fluid so that the die will be immersed in the cooling fluid. The interior of the tank is kept under reduced pressure. At the inlet side of the die, a pre-cooling unit is provided which supplies a cooling fluid to the outer periphery of a resin tube which have been heated to a temperature above its softening point beforehand. The tube is expanded at least by the suction force applied thereto while passing through the die kept under reduced pressure. The cooling fluid in the tank and that supplied from the pre-cooling unit serve to reduce the friction between the tube and the inner periphery of the die, thus preventing the tube from expanding lengthwise. A jacket may be provided around the die to supply the cooling fluid.
