Patent CA-1329842-C (CA)
Inventor: BALLINGER FORREST H
IPC: B61L29/28

Abstract: ABSTRACT OF THE DISCLOSURE             An island circuit detects the presence of a train on a crossing island, and, in response, de-energizes a normally energized relay to activate a warning.  A random signature signal is generated and transmitted through the rails from a transmitter to a receiver connected to the rails on either side of the island.  If a train is present within the island, the wheels and axles form an electrical shunt, preventing the receiver from detecting the transmitted signal.  The circuit employs solid state micro-electronic components and ancillary components, and embedded software for controlling and monitoring the circuit functions.  The random signature signal is characterized by a relatively high voltage level but a low duty cycle on the order of ten percent, and has three variablea: (1) frequency; (2) duration time of the pulse, or burst, of the signal; and (3) the delay between successive bursts.  Each of the three variables randomly assumes any one of eight different discrete values.  Each time a signal is received, the detector checks to determine whether the received signal matches the transmitted signature signal.  If three consecutive transmitted and received signals do not match, the island warning device is activated, and then five consecutive matched signals are required to reset the system and cancel the island warning.  This feature allows the island circuit to discriminate against signals from other island circuits or recover from a temporary malfunction, and return to normal operation.

Abstract: A method and an equipment for wireless transmission of telephone calls between a stationary unit (1) connected to a telephone set (3) at a short distance from the stationary unit provides that all pairs of units (1, 3) have access to a plurality of common duplex radio speech channels for transmission of calls, and to a common radio signalling channel for transmission of signals referring to connection and disconnection of the speech channels. The radio speech channels are assigned after adaptive channel scanning in that they are listened to before a call, and a channel selected which is idle with respect to calls. The selection of an idle channel takes place automatically with the use of radio receivers (12, 25), channel selectors (15, 28) and circuits (16, 29) incorporated in both units.

Abstract: A projectile comprises a pyrotechnic charge and a mobile member inside the projectile which rotates between a safe position and an armed position. At least part of a pyrotechnic delay device is accommodated in a passage in this mobile member. The pyrotechnic charge is initiated via this pyrotechnic delay device. The passage is oriented so as to isolate functionally the pyrotechic delay device from the pyrotechnic charge when the mobile member is in the safe position. It functionally couples the pyrotechnic delay device to the pyrotechnic charge when the mobile member is in the armed position. The projectile further comprises an arrangement on the mobile member and on the projectile to guide relative rotation between them about an axis fixed relative to the mobile member and relative to the projectile. A mechanical arming device retains the mobile member in the safe position and against rotation about the aforementioned axis relative to the projectile at least until the projectile is fired. It obliges the mobile member to move to the armed position when the projectile is fired by rotating about the axis relative to the projectile.

Abstract: A machine for transforming heat shrinkable thermoplastic material into sealed and liquid-filled containers in which the material in strip form is cut off to a suitable length then heated and transformed into a tube-shaped shell blank on a mandrel with an overlapped longitudinal heat-sealed seam. The shell is then displaced in relation to the mandrel so that its bottom end extends beyond the end of the mandrel, a base blank cut from another strip is then inserted into the end of the shell to rest against the mandrel end, and the shell and inserted base are then heated causing the shell to shrink accurately to the shape of the mandrel and the bottom edge zone of the heated shell to be folded in against the end of the mandrel and the edge of the base. The joined edge zones of the shell and base are then pressed together and heat sealed. The container is then passed to a filling machine where it is filled and closed by a lid.

Abstract: Apparatus for producing sterile air suitable for being administered to intensive-care patients in hospitals using atmospheric air. The medical-grade air is free of gaseous contaminants and germs, at a cost substantially lower than when such air is prepared by mixing pure nitrogen with pure oxygen. Atmospheric air is compressed through at least one dry-piston compressor, condensing water vapor out of the compressed air through expansion into a buffer tank, filtering out dust particles down to micron size in a prefilter, drying the air through an adsorption desiccator unit and eliminating gaseous contaminants through an adsorption-desorption unit. A second dust filter is provided for trapping any dust released from the adsorption units. Biological contaminants, such as viruses and bacteria, are eliminated by flowing through a sequence of three biological filters of the coalescence type, and finally through a cold sterilizing unit. The desiccator unit and the unit for the elimination of gaseous contaminants contain a compound of metal oxides with silicates K, Na and Mg, the amount of this compound being larger in the elimination unit than in the desiccator unit.
