Abstract: GAMMA CAMERA SYSTEM                       ABSTRACT   A gamma camera system having control components operating in conjunction with a solid state detector. The detector is formed of a plurality of discrete components which are associated in geometrical or coordinate arrangement defining a detector matrix to derive coordinate signal outputs. These outputs are selectively filtered and summed to form coordinate channel signals and corresponding energy channel signals. A control feature of the invention regulates the noted summing and filtering performance to derive data acceptance signals which are addressed to further treating components. The latter components include coordinate and energychannel multiplexers as well as energy-responsive selective networks. A sequential control is provided for regulating the signal processing functions, of the system to derive an overall imaging cycle.

Abstract: Abstract of the Disclosure A freezing or cooling plant comprises an apparatus having an evaporator chamber. At the lower end the apparatus is connected with a feeding conduit for liquid refrigerant and a suction conduit for sucking out refrigerant vapours. Both conduits commu-nicate with a vessel in such a way that liquid refrigerant from the apparatus may flow to the vessel via both the conduits. By heating the apparatus due to washing of the outer surface of the evaporating chamber of the apparatus, only moderate pressure rises will occur in the apparatus due to the fact that the apparatus, after the stopping of the cooling process will be emptied for liquid refrige-rant and during the remaining washing period will contain solely super-heated refrigerant vapours.

Abstract: Abstract of the Disclosure A signal synchronization system is disclosed which samples an incoming stream containing binary information at a sampling rate which is an integral multiple of the bit information rate.  This system correlates the sequences of the sampled bit pattern with a predeter-mined sequence to produce a measure of the dissimilarity between the sampled and the predetermined sequences.          Synchronization of a local sampling clock with the incoming binary information is achieved by making phase adjustments to the local sampling clock which are func-tions of both the magnitude of dissimilarity and the time of measurement.

Abstract: ABSTRACT          "SYNCHRONISATION OF ELECTRICAL OSCILLATORS"                  A system for synchronising remote or co-located oscillators is constructed with redundancy enabling a high degree of fault toleration. In the various embodi-ments of the system there is no predetermined hierarcy amongst the oscillators in contrast to the prior art master and slave type of synchronisation.  Averaging is not involved and the system settles to a state in which the oscillators are locked to one master, which is not predetermined.  Each oscillator is part of a terminal which includes reconfiguration circuitry, and each, in the absence of faults, is connected to each of the other terminals.  The terminals attempt to lock to another oscillator and recon-figure in accordance with an algorithm until stable synchronisation is achieved.  In one embodiment the properties of a phase-locked loop are utilised in a novel way by incorporating a variable delay in its feed back path.  Using this circuitry enables one embodiment to achieve synchroni-sation even when only indirect paths exist to the assumed master, and in the system temporary disconnection for reconfiguration is not necessary.

Abstract: RESILIENT DEFLECTOR FOR SNOWPLOWS                 ABSTRACT OF THE DISCLOSURE A resilient deflector for snowplows tapers to a blunt edge as it extends outwardly from the top edge of the snowplow blade, generally across the entire length of the blade. By aligning the deflector with the snowplow blade working surface, the blade working surface area is extended, aiding in funnelling the snow outwardly of the blade and decreasing the. tendency of the snow to billow rearwardly, over the blade, obscuring a snowplow operator's field of vision. Since the deflector is resilient its curva-ture may vary automatically in response to the plowing speed and the accumulation of snow on the snowplow blade working surface.
