Patent CA-1068218-A (CA)

Abstract: Abstract of the Disclosure A control system for an audio amplifying system which has a plurality of microphones producing individual output signals. Each microphone has an analog switch connected thereto for turning the microphone on and off in response to a control signal which is produced by a control means which is responsive to the output signal of the microphone for enabling the analog switch when the microphone output signal is above a predetermined threshold level. A reference signal is supplied to the control means for establishing the threshold level at which the control means enables the analog switch. This reference signal is modulated according to the amplitude of the microphone output signal so that the threshold level of the control means is automatically varied to avoid enabling the analog switch in response to undesirable audio signals. More specifically, the reference signal is preferably modulated in direct proportion to the amplitudes of the envelopes of the output signals of the microphones that are turned on so that the thresholds of the control means are increased in direct proportion to the amplitudes of the envelopes of the microphone output signals, thereby varying the sensitivities of the microphones in inverse proportion to the amplitudes of the envelopes. The control system also includes a plurality of delay circuits each of which is responsive to a termination of the output signal from one of the control means for enabling the corresponding analog switch for a predetermined time interval after the microphone output signal drops below its threshold level, thereby keeping the microphone turned on during normal pauses in the audio input to the microphone. The system also includes a reset feature for automatically resetting the entire system whenever output signals are produced simultaneously by two or more of the control means; an audio signal that produces such a response is presumed to be undesirable and the resetting of the system prevents the transmission of such an audio signal. The system also includes a limiting feature which permits more than one microphone to be on at the same time, while limiting the maximum number of microphones that can be on at the same time. However, even when more than one microphone is allowed to turn on at the same time, the microphones must turn on and off at intervals greater than predetermined minimum intervals or "stages". The microphones may also be turned on and off by manually operated switches rather than by the audio input signals, if desired.

Abstract: ABSTRACT OF THE DISCLOSURE           An interface device for the remote control of pulse activated, mechanically held relays or master switches by control devices which have a continuous output, such as time clocks, security system devices, and thermostats.  The presence of a continuous input signal is decoded by the electronic circuitry into a momentary output signal to be applied to the "on" side of a remote control relay. When the input signal is removed, the device decodes this lack of signal and produces a momentary signal to be applied to the "off" coil of the relay.  Input terminals are provided with four types of input signals - 120 volts AC, 12 volts DC, a contact closure, and a contact opening.  Three output terminals are provided, namely, "common", "on", and "off" terminals for connection to the remote control relays. Another set of terminals can be provided to allow the use of an external power supply load with the device, by incorporating a control relay within the device capable of handling 20 amps.  Also several sets of "on" and "off" output terminals which are isolated from one another can be provided.

Abstract: ABSTRACT OF THE DISCLOSURE          A microprocessor control complex for a telecommunications switching system disclosed in the context of a digital time division multiplex switching system.  The control complex is arranged as a cluster of hardware identical microprocessors in a distributed processing configuration wherein each microprocessor is provided with its own memory and clock and is programmed to perform a portion of the total function of the switching system.  Each microprocessor performs the functions assigned to it independently and asynchronously of the others.  Data is transferred between microprocessors in a manner which minimizes the amount of time spent in interprocessor communication.  This communication is accomplished via interprocessor buffers which provide dedicated communication channels between partner processors while allowing those processors to continue to operate asynchronously.  The distributed control complex allows the software to be modularized with resulting economics in program generation and debugging.

Title: Calculated parameter generation in a hematology parameter measurement apparatus
Inventor: HENNESSY JAMES W
IPC: A61B5/145
Filed: 1977-10-19
Granted: 1981-12-08
Abstract: Abstract In a hematology parameter measuring apparatus, signals indicative of measured parameters are obtained and loaded into first digital registers. Calculated parameter values are generated through use of the values stored in the digital registers. A first parameter value is circulated from a register into a digital divider through a digital data line to set a divisor in the divider. A control circuit circulates a value from another register to the divider for utilization as a signal indicative  of a dividend. The output of the divider is coupled to a result register to store a value indicative of the calculated parameter. In this manner, calculated parameter values are obtained, and the first registers retain values indicative of the measured parameter values. The control means may selectively couple signals to a display from any of the registers or to a printing unit.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a reversible seat in which the seat back is movable from a first position at one end of the seat cushion, across the upper surface of the seat cushion, to a second position at the other end of the seat cushion, with the seat back remaining in a substantially vertical disposition through-out the movement.  Such seats usually include means to change the inclination of the seat cushion in response to movement of the seat back.  The bottom of the seat is usually latched so as to prevent removal from the support-ing frame.  However, the common form of latching means is a single latch which does not prevent tilting move-ment of the seat which may be experienced by the occu-pant.  The bottom surface of the seat of the present invention includes locking means which cooperates with latching means attached to the frame supporting the seat. With the backrest in either the first position or the second position the locking means is engaged with the latching means and prevents removal of the seat from the supporting frame.  With the backrest located in an intermediate position between the first position and the second position, the seat is readily removable from the supporting frame.  The locking means takes the form of one locking member located adjacent to the forward edge of the seat with a separate  locking member located adjacent to the rearward edge of the seat so as to posi-tively lock the seat in position.

Abstract: ABSTRACT A method of manufacturing a fire-screening glazing panel comprising at least one layer of intumescent material sandwiched between two structural plies of the panel, includes the steps of forming the layer and securing the plies together. In order to avoid or reduce problems associated with drying the intumescent layer, an assembly is made in which the structural plies sandwich a layer of intumescent material formed from at least one material of which at least the greater part by volume is in granular form.  In a second aspect, in order to facilitate degassing of the intumescent layer, such layer contains intumes-cent material of which at least part is in the form of grains, and the intumescent material is subjected to suction at the edges of the assembly in a degassing step and the assembly is subjected to heat and/or pressure conditions to cause the grains in the layer to become assimilated into an intumescent body which bonds the structural plies together.  The invention includes an intermediate product for forming a multi-ply fire-screening glazing panel, comprising a structural ply of glazing material bearing an adherent layer of which at least the greater part by volume consists of grains of intumescent material.
