Patent GB-279938-A (GB)
Title: Improvements in or relating to telegraphic and the like communication systems
IPC: H04L7/08
Filed: 1926-08-03
Abstract: 279,938. Smith, W. S., and McLachlan, N. W. Aug. 3, 1926. Synchronous movements.-In a composite telegraph system, including e.g. land-line, cable, and radio sub-systems, synchronous movements of the instruments, e.g. regenerator or picture telegraph instruments, at the various stations are effected under control from a constant frequency master oscillator or alternating current generator at a central station by the use at intermediate or substations of means for changing the frequency to values suited to the various sub-systems. The synchronizing oscillations may be transmitted over the signalling channels with provision of suitable filters in connection with the instruments or separate channels may be provided in which case filters are unnecessary. Fig. 2 shows an arrangement for an intermediate station in which the synchronizing frequency received with thesignalling currents over the cable C and amplified at A is further amplified by transformers T<1>, T<2> connected by valves V in push-pull relation. The output current is supplied by leads W<1> to a synchronous motor driving the local apparatus to be synchronized and by leads W<2> through frequency converters, with or without filters, to the next cable section or synchronizing circuit. Alternatively the leads W<2> may be taken from theinput side of the transformer T<1>. Fig. 3 shows an arrangement for automatically bringing into operation at an intermediate or sub-station a local auxiliary oscillator upon failure of the synchronizing frequency from the central station. Thereceived currents amplified at A are supplied to a further amplifier PA and to a relay RX, and when the current through this relay falls to a pre-determined value a contact is closed at R to connect up the auxiliary oscillator AG.

Abstract: 1,145,657. Measuring particle concentration in atmosphere. SAAB A.B. April 27, 1967 [April 27, 1966], No.19531/67. Heading G1A. In an arrangement for determining the concentration of particles in a gaseous atmosphere a plate is placed in the atmosphere for a period of time determined by a time switch and is then exposed to a beam of light parallel to the surface, the amount of light deflected in a direction away from the plate being measured as an indication of the number of settled particles. A portable apparatus includes a withdrawable and retractable drawer in which the plate is accommodated, means for adjusting the plate exposure time, a meter and range change switch, and an optical inspection and sizing tube. The light source is fed from a voltage regulated supply and is directed across the plate surface through lenses and an aperture. Light deflected by the particles in a direction perpendicular to the plate is detected by a photocell, and converted to an electrical signal at indicating by its voltage current or frequency the number of particles. In a modified arrangement two beams of light are directed at right angles across adjacent sides of the plate to vertical mirrors which return the beams across the plate so that the particles are illuminated from all sides to improve sensitivity. The plates may be exposed in remote spots and brought in sealed containers to the measuring apparatus.
