Inventor: CHIN ALBERT K
IPC: A61B17/56
Filed: 1990-04-03
Abstract: A method and apparatus for removing a pre-placed prosthetic joint from a bone cavity and conditioning the cavity for receipt of a replacement joint. The pre-placed joint is first pulled from the mantle of hardened cement holding it within the cavity, thus leaving a cavity within the mantle. A mass of fluid cement is then placed within the cement cavity, after which a pulling appliance is inserted into the fluid cement and the fluid cement is permitted to cure to bond the appliance to the mantle. Tension is then applied to the pulling appliance to remove the appliance and the cement mantle from the bone cavity as a unit. The fluid cement partially dissolves and softens the hardened cement mantle so that an integral cement mass is formed upon curing of the fluid cement.      The pulling appliance is of a screw-like configuration, with means to connect a slap-hammer to its proximal end.

Title: Capacitive sensing, solid state touch button system
IPC: H03K11/00
Filed: 1990-08-24
Abstract: Abstract CAPACITIVE SENSING, SOLID STATE TOUCH BUTTON SYSTEM          A  solid state touch or control button assembly (10),  with no moving button parts  and operated by capacitive sensing by monitoring the phase shift of a signal applied to the face of the button, including in a first embodiment (Figs. 2A & 2B) a auto balancing button and in a second embodiment (Figs. 3A & 3B) a constant pressure button.  If skin or other material comes into contact with the touch surface,  the capacitance  is changed and sensed, causing the electrical or electronic function controlled by the touch button to be activated (or deactivated, depending on the design, or otherwise altered).   LEDs then are activated, providing visual feedback to the button pusher through a light ring (2A) surrounding the button surface (1).  False activation of the button by residual impedance and external influences, such as temperature change, cleaner residue build-up and other deposits, are avoided by compensating for them by slowly auto balancing to all such phase shifts, with the rate of auto balance being set to be faster than the rate of change of the steady state phase shift; and, addi-tionally, false activations by noise transients, includ-ing those due to EMI,  RFI  and other environmental fluctuations, are avoided by delaying the activation of the button by an appropriate amount of time, such as, for example, of the order of about one hundred (100 msec.) milliseconds.

Abstract: A b s t r a c t o f D i s c l o s u r e s . A s a c o n s e q u e n c e o f n e g l i g e n c e and abuse of Global Laws and Orders,living species of the Earth are endangered by the growing forces of destruction caused by human greed, carelessness and ignorance.By the end of 20th century it is acid rain, the greenhouse effects and nitrous oxides, which become time bombs in our biosphere.(Approximately 200 carcinogenic compounds exist). Is the ozone depletion in the Antarctic an isolated phenomenon or is it a warning of a slowly progressing ozone destruction worldwide.(The decline over the past eight years is 4% to 5% . In the description of this invention,the main stages of the extermination of the infesting waste ?ctration are visible when processed in the following operations: 1. Removing hard particles from the flues of any combustion boilers by centrifugal forces or pressurized air. 2. Cleared fumes are passed through wire-mesh(between fire-proof layers maintaining catalytic extractors)separating sulfur oxide to be removed along side outlets after being subjected to water vapor. 3. The fumes separated from hard particles will enter combustion chambers with batteries of fire resistant channels equipped with high temperature burners invigorated by the injection of air or pure oxygen. 4. Partially burned toxins flow through the top of catalytic filters in the chimneys and smokestacks.The monitors incorporated into this system will register escaping toxic gases,but the fumes will be burned in the second or even third combustion chamber installed above or beside the first until toxic gases are eliminated. The air ,indispensable to all living creations is being poisoned as a result of defective systems of production and inefficient tools infesting public space and daily activities. Therefore the same combustion system ought to be a significant part of clearing the air by way of the nets of suction pipes,hoses or tubes installed above any infested public space. Consequently,the general health will be greatly improved and national medical expences reduced. Finally,the elimination of toxic fumes from any combustion boilers,ventilator incinerator or diesel exhaust should clear the atmosphere of the already suffocating Earth,and prolong a healthy existence of all living creatures. Above all,this system will establish a powerful safety zone against any attack by chemical warfare strategists.

Abstract: In a method and configuration for forming a line termination at two line terminals of a telephone line, alternating signals are separated from direct signals applied to line terminals, referred to a reference variable and added to a transmission signal from a transmission terminal to form a resultant actual-value signal. The resultant actual-value signal is compared with a reference signal at a gain-controlled amplifier. The reference signal is formed with an impedance transmission function corresponding to a given termination impedance by weighting the alternating signal at one of the line terminals being connected to a current sensor resistor. A current between the line terminals is determined with a control transistor associated with the current sensor resistor. The control transistor is controlled with the gain-controlled amplifier.

Title: Cellular mobile radio system
Inventor: HEIDEMANN ROLF
IPC: H04B10/00
Filed: 1991-01-31
Abstract: ABSTRACT OF THE DISCLOSURE      In a mobile-radio system with a switching center and with base stations, in which the base stations (FS1-FSn) transmit radio signals of mobile subscribers (MS) and receive these from them, according to the invention, the radio signals are not generated or processed in the base stations, but in the switching center (1).  The switching center (1) thus contains a microwave transmitter/receiver (SE1-SEn) for each base station (FS1-FSn) which converts the signals to be transmitted to the base stations into radio signals and converts the radio signals received from the base stations into the base band position.  This has the advantage that carrier frequency devices can be used jointly for a large number of base stations, so that the costs of the system are reduced.

Title: Control process and trigger equipment for damping resonant vibrations of a parallel-resonant circuit for a pulse-controled inverter of a c urrent-source inverter
Inventor: HEINLE GEORG
IPC: H02M5/45
Filed: 1991-02-05
Abstract: ABSTRACT OF THE DISCLOSURE     A control process and trigger equipment damps resonant oscillations of a parallel-resonant circuit for a pulse-controlled inverter of a current-source inverter.  The pulse-controlled inverter contains turn-off current-converter switches and is linked to an inductive and to a capacitive load.  This inductive and capacitive load forms a parallel-resonant circuit.  A modulation mode is selected from several stored modulation modes from the system frequency (f1) of the converter current (IR).  Depending upon a calculated factor (f1/fres) and the  selected modulation mode, switching angles (.alpha.1, .alpha.2, ..., .alpha.n) are determined depending upon system frequency by means of stored, pre-set switching angles.  From these switching angles the control times for the pulse-controlled inverter are then generated.  Thus, the pulse edges of a selected modulation mode can be adjusted with the system frequency as a function of frequency, enabling the resonant oscillations to be adequately damped over the entire system frequency range.

Title: Adaptive pulse width optical fault finder
Inventor: BUERLI RICHARD
IPC: G01M11/00
Filed: 1991-03-06
Abstract: Abstract of the Disclosure An optical fault finder which optimizes the pulse width of the test signal which is transmitted through an optical fiber.  The fault finder is an optical time domain reflectometer (OTDR) having a variable pulse width light source and associated timer. When a first test signal is launched down the optical fiber, a microprocessor within the OTDR detects any discrete losses and records the signal level at these faults. The OTDR then launches subsequent test signals whose pulse widths have been optimized according to the signal level at each fault.  Also, a novel processing technique utilizes a matched filter to provide greater sensitivity to loss detection and location of the corresponding faults.
