Title: Fire safety device
Inventor: ROBERTSON ERIC B
IPC: E04B1/94
Filed: 1991-12-30
Abstract: ABSTRACT OF THE DISCLOSURE              A fire safety device for closing through-holes in floors and walls  and for thus stopping the potential spread of fire and smoke in case of the occurrence of a fire, includes a section of pipe having a weakened wall, a cup-shaped retainer spaced from the outside surface the pipe section so as to define an annular space therebetween, the annular space in turn being provided with a suitable and pre-measured quantity of intumescent material. The device is pre-fabricated and thus avoids the problems inherent in attempting to manually provide the intumescent material in a collar during construction.

IPC: H04M1/60
Filed: 1992-01-17
Abstract: A white noise suppressing circuit for suppressing white noise contained in a received voice of a speaker telephone apparatus includes a filter for suppressing white noise contained in an aural input signal input to an aural signal line, a switch for short-circuiting the filter, a detecting circuit for detecting the aural input signal, and a comparator for comparing an output of the detecting circuit with a preset voltage and for controlling the switch on the basis of the results of the comparison.  When it is determined by the comparator that there is a voice input, the switch is short-circuited to make the filter inoperable.  When there is no voice input, the switch is opened so as to make the filter operate.

Title: Synchronizing circuit
Inventor: SEVENHANS JOANNES M J
IPC: H04L7/033
Filed: 1992-03-04
Abstract: J. SEVENHANS - J.J. SCHMIT 9 - 2 ABSTRACT          SYNCHRONIZING CIRCUIT Three signal samples (A25, C26, B27) of a digital signal DATA are taken simultaneously in three different time positions (t25, t26, t27) of this signal and separated by a small time interval (T).  As long as the three signal samples are equal it may be deduced therefrom that the three time positions occur within the duration of a same data bit of DATA and a new set of three time positions (t24, t26. t28) of which the time interval separating them is increased is then taken, the latter set being thus "expanded" over a larger region of this data bit.  If, on the contrary. a signal sample (B28) is different from the two others (A24. C26) it may be deduced therefrom that only two time positions (t24. t26) occur within the duration of a data bit.  A new set of three time positions (t24, t25. t26) is then taken with the initial small time interval (T) and with the new medium time Position shifted over this time interval (T) to the left or to the right depending on which of the signals samples is different from the others. If the three signal samples (A24. C25. B26) taken in the three new time positions are then equal, the above process is repeated. In conclusion. when the "largest" set of time positions (t12, t20. t28) is obtained. the medium time position thereof (t20) always occurs in the middle of a data bit and the signal sample (C20) taken in this medium time position is optimum for representing this data bit and for generating another digital signal synchronized with the J. SEVENHANS - J.J. SCHMIT 9 - 2 clock signal CLOCK.

Patent CA-2078013-A1 (CA)
Inventor: MUEHLBERGER ERICH
IPC: B05B7/22
Filed: 1992-09-11
Abstract: Apparatus for delivering heated powder to the plasma gun of the thermal spray plasma system includes a hollow heater tube coupled between a powder feeder and the plasma gun and a power supply coupled between opposite ends of the heater tube.      The power supply heats the walls of the heater tube to a temperature below the melting point of the powder particles, to prevent melting and adhesion of the particles thereto. The length of the heater tube is selected to provide an adequate dwell-time of the powder particles therein for a given powder flow rate, so that even relatively large powder particles are heated to a temperature relatively close to that of the heater tube walls upon delivery to the plasma gun. The efficiency of the heater tube is improved by a water cooled reflector tube concentrically disposed about the outside of the heater tube, with oxidation of the tube surfaces being prevented by a flow of inert gas along the space between the heater and reflector rubes.      The heated powder delivery apparatus can be used by itself and without the plasma gun to effect thermal spraying in instances where the powder is of the type that can be heated close of the melting point without adhering or clogging. One or more ring-shaped electrodes and associated DC power supplies can be disposed within the plasma stream to provide additional powder particle heating and control within the plasma stream itself.
