Abstract: A B S T R A C T A digital radio paging system comprising a transmitter at the central or base station and receivers at different remote stations.  The transmitter generates in a predetermined sequence a preamble digital signal, a calling digital signal and an end mark digital signal.  A carrier wave is modulated by this sequence of digital signals and the modulated carrier wave is received by the receivers where it is demodulated into the preamble digital signal, calling digital signal and end mark digital signal.  The receivers also recover from the modulated carrier wave a clock pulse synchronised with the detected digital signal sequence.  Demodulation is brought about under the action of a power source the voltage of which may be controlled in response to detection of the preamble digital signal and end mark digital signal or in response to a series of pulses of predetermined period generated in the receivers.

Abstract: ABSTRACT          A probe for obtaining particulate-free samples of gas from a smoke stack for a power plant or other in-dustrial installation.  The probe comprises a coarse filter, with means for  periodic cleaning by blowback, protecting the inlet to an inertial filter.  A high velocity flow of coarsely filtered stack gas is estab-lished through the inertial filter.  Sample gas is withdrawn from the inertial filter at a low rate in a direction orthogonal to the gas stream through the inertial filter so as not to disturb particles in the inertial filter stream.  The invention eliminates the necessity for frequent maintenance of stack mounted filters or other stack mounted components.

Abstract: APPARATUS FOR WASHING THE FILTER MEDIUM OF A FILTER BED            Abstract of the Disclosure An apparatus is provided for washing the filter medium of a filter bed and includes an agitator having a generally vertically extending tubular member.  The vertical tubular member has a first end for receiving wash water and a second end extending into the filter medium.  The apparatus further includes at least two generally horizontally extending tubular members with a first group of nozzles being mounted on one of the horizontal tubular members, each nozzle in the first group being directed downwardly at a small angle from the horizontal.  A second group of nozzles is mounted on the other horizontal tubular member with each nozzle in the second group being directed upwardly at a small angle from the horizontal.          Wash water is supplied to the first end of the generally vertically extending tubular member.  The vertical tubular member and the horizontal tubular members and both groups of nozzles are in fluid communication, whereby wash water supplied to the vertical member will cause jets of wash water to be delivered from the nozzles to the filter medium and will rotate the horizontal tubular members in a substantially horizontal plane and wash the filter medium.  Means are provided for balanc-ing the vertical forces created by the jets of wash water from the nozzles.  In a second embodiment, an additional pair of horizontal tubular members is provided above the filter medium with one horizontal tubular member including a first group of nozzles, each nozzle in the first group being directed down-wardly at a small angle from the horizontal, and with the other horizontal tubular member including a second group of nozzles mounted thereon with each nozzle in the second group also being directed downwardly at a small angle from the horizontal.

Abstract: ABSTRACT OF THE DISCLOSURE        A repeating animal trap particularly for rodents such as rats and mice has a trapping passageway into which animals are attracted due to their inherent curiosity. A trigger within the passageway is tripped by animal pressure and this sets ir. motion a reciprocatory sweeping mechanism which sweeps the animal from the passageway into an adjacent collecting compartment.  The reciproca-tory mechanism then returns to its initial position in which it defines longitudinal walls of the passageway to effectively prevent an animal in the collection compartment from pushing its way back into the passageway. A constant force coil spring is used to power the sweeping mechanism with a control system that insures only  a single reciprocation of the sweeping mechanism each time the trigger is activated 80 that the trap operates effectively on successive animals throughout the range of displacement of the spring.

The nozzle or nozzles for the reactants are installed above a breast-like taper in the lower open end of the device.  The process can be carried out at standard pressure, excess pressure or at negative gauge pressure.
