Title: Induction heating method and apparatus for use in causing necrosis of neoplasm
Inventor: RAND ROBERT W
IPC: A61K9/50
Filed: 1982-01-07
Abstract: Induction heating can be utilized to cause necrosis of neoplasm as a result of hyperthermia by a process involving the injection of particles having hysteresis heating characteristics into tissue either within or in close proximity to the neoplasm and then subjecting these particles to an alternating magnetic field sufficient to cause hysteresis heating. The frequency of the field is preferably sufficiently low so as to minimize eddy current and dielectric heating. The particles used are preferably initially located within a biologically inert liquid carrier which will facilitate the insertion of the particles within the body and which will automatically become non-liquid within the body so as to hold the particles in place. The actual heating is preferably carried out by positioning either the entire patient or the affected portion of the patient's body through a series of axially aligned, parallel, liquid cooled coils (12). Only one of these coils (12) is connected to a power supply (30).

Filed: 1982-05-11
Abstract: A weighing system (210) which includes a force input member, such as a weighing pan (212), and rigid armature (226). A first linkage (110) couples the armature (226) to a reference member, or housing (220), in a manner constraining the armature to motion along a reference axis (216) fixed with respect to the reference member. In general, this linkage is particularly resistant to applied moments. A second linkage (160) resiliently couples the force input member (212) to the armature (226), permitting a relatively large range of linear relative motion of those elements. A low friction damper (218) is coupled between the force input member (212) and the reference member (220) to damp the relative motion of the force input member and the housing. A force transducer (10) is coupled between the armature (226) and the reference member (220). The transducer (10) includes a pair of complementary opposed surfaces having a mutual separation which is related to the force across the transducer. A position sensor (224) coupled to the transducer (10) generates a signal representative of the separation between the complementary opposed surfaces of the transducer.

Title: Detector circuit for communication lines
Inventor: TUREK GREGORY JEROME
IPC: H04M7/00
Filed: 1982-09-02
Abstract: A detector circuit (214) for detecting the on-hook and off-hook states of a communication line includes current and voltage sensors (410 and 415, 416) for generating two reference signals. One signal represents the current flowing in the line; the other represents the voltage on the line. A comparator circuit (412-414, 420, 421) compares these two references to generate an output signal representative of the on-hook state when the magnitude of one of the references is greater than the other. When the magnitude of the one reference signal is less than the other, the comparator circuit generates another output signal representative of the off-hook state of the line. In addition, when the line is electrically isolated from ground, the two comparator output signals may drive an opto-isolator (431) to generate two corresponding output singals (at 419) electrically isolated from the comparator output signals.
