Title: Improvements in frequency modulation systems for radio communication
IPC: H04B14/00
Filed: 1941-08-29
Abstract: 548,599. Frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 29, 1941, No. 11090. Convention date, Aug. 31, 1940. [Class 40 (v)] The carrier wave is frequency-modulated by a sub-carrier or tone frequency which is itself varied or modulated by the signal; and at the receiver certain side-band groups are separately received, detected, and combined as in diversity reception. The object is to avoid selective fading, and to enable frequency modulation to be used on long-distance short-wave systems. Fig. 1 indicates diagrammatically some of the side frequencies resulting from the frequency modulation of a carrier f0 by a sub-carrier frequency. These side-frequencies are shown in full lines and are spaced from the carrier fo and from each other by a distance representing the subcarrier frequency. When the sub-carrier is frequency-modulated by the signal, groups of sidefrequencies are created as shown in dotted lines. At the receiving station, certain of these groups are selected by geographically separated aerials 1 ... 4 tuned to their mean frequencies and after one or more stages of frequency reduction 5 ... 8, are passed through amplifiers 9 and limiters 10 to frequency-modulation detectors 11. The outputs are fed in parallel to the receiving instrument 12, and arrangements may be provided whereby only those receivers giving the best results are utilized. The Specification includes a tabular statement indicating for a particular case the amplitude and phase of the components of the various groups. Those groups are chosen in which the phases of the components do not change, and the amplitudes are comparatively uniform. Groups extending beyond the useful frequency range may be suppressed at the transmitter.

Title: Improvements in or relating to electrically heated floors
IPC: F24D13/02
Filed: 1943-07-08
Abstract: 570,251. Floors. SHAW, C. July 8, 1943, No. 11101. [Class 20 (iv)] [Also in Group XI] An electrically-heated floor comprises a concrete foundation covered by a heat and electric insulation layer of cork or rubber or synthetic rubber, on which is arranged an electrically conducting grid or sheet such as a metal foil, gas black, or graphite layer, a surface layer being then added consisting of a paste of polyvinyl chloride and tricresyl phosphate. The surface is solidified by heat derived from the heating element. The surface layer may be preceded by a further'layer of insulation comprising a mixture of granulated cork and rubber. This may also be heated in situ to expel air. The heating resistance, when of carbon, may be applied as a paste on the insulation or as a woven fabric or paper coated with carbon. Connection may be made by means of strips of metal foil at intervals.

Abstract: 1287682 Slitting the necks of poultry STORK AMSTERDAM NV 9 March 1970 [25 March 1969] 11102/70 Heading A2U A device for making longitudinal cuts in the backs of the necks of poultry carcases suspended by the legs from shackles 2 on a conveyer 3 preparatory to removal of the windpipe, crop &c., comprises an inclined disc 7 with protruding knives 13 in holders 12 alternating with downwardly and outwardly projecting guides 10. The spacing of the knives corresponds with that of the carcases on the conveyer, and the disc is driven by a shaft 6 depending from a wheel 4 around which the conveyer changes direction through 90. The necks of the carcases enter the spaces between the guides 10, which lift the wings, and the necks then pass behind a fixed, curved guide 14 which may have a protective guard 15, to be pierced by the knives near the shoulders of the carcases after which, due to the inclination of the disc, the cuts are extended towards the heads during approximately a quarter of a turn of the disc. Location of the necks may be assisted by recesses in the disc between the guides 10, and the knives may be readily replaceable.

Cells; diaphragms; electrodes; electrolytcs. circulating.-An oxygen-hydrogen generator of the kind in which dished electrodes form a cell is provided with a separable liquid-supply and gasvent device. In the three-electrode cell shown in Fig. 2, each compartment contains such a device 87, partly immersed in the liquid. Clamps 25 secure together the edges of the electrodes, and a foot 67 on one electrode supports the whole structure. Ribs 29 are provided on the electrodes. Thin frames clamped between the electrodes but separated therefrom 'by packing support diaphragms of asbestos or like material not liable to act as a bipolar electrode. The broad upper sides of the frames separate the three gas chambers. Passages for electrolyte connect the compartments below and above the diaphragms. Inlet pipes 86 for electrolyte lead to the devices 87. In each of these the liquid passes through an opening 70, Fig. 5, down a passage 71, around the end 75 of a longitudinal partition 74, through a port below the rear part of the passage 71, and out by an opening 79. If any electrolyte is forced back into the supply pipe, it returns through the circuitous passage and is separated from gas, which escapes into the space at the top of the cell. The device allows gas to escape through the pipes 86 if the liquid level is too low.

Abstract: 456,846. Dispensing syrups &c. LYONS & CO., Ltd., J., and MAYNE, D., Cadby Hall, Kensington, London. April 16, 1935, No. 11719. [Class 116] [See also Group II] An apparatus for dispensing liquids consisting of a mixture of one liquid, such as syrup, from a bottle, with another liquid such as water from a supply, comprises a bottle holder, normally upright, but invertible to a delivery position and a tap connected to deliver the water at the same time as the syrup from the bottle, the delivery of the two liquids being in predetermined proportion. The bottle holders comprise shallow cups 4 connected by diametrically located members 5 to a screwed cap 6, the bottle 1 being secured in its holder by a valvebox 2 which seats on the neck of the bottle and has a flange 9, Fig. 3, clamped by a nut 7 to the screwed cap 6 of the holder. The cups 4 may be loaded to return the holders to upright position after dispensing, the holders being mounted on trunnions 12 in arms 13 on a wall &c. bracket whose base is formed with a conduit 27 supplying water to all the dispensing devices. The valve-box 2 is formed with a throughpassage 14, Fig. 3, for the delivery of syrup and with a passage 21 connected to a tube 22 extending to the bottom of the bottle to allow air to flow in during delivery, the passages 14, 21 being controlled by piston valves 16, 23 mounted on a common spindle 17 and normally maintained in closed position by a spring 18 and nut 19. When the holder is inverted, the nut 19 engages a fixed stop 20 and causes the passages 14, 21 to be opened thus allowing syrup to be delivered into a receptacle. Simultaneously, a yoke 30 pivoted at 31 is engaged by the valve-box and through an adjustable abutment 32 opens a valve 29 thereby delivering water from the conduit 27 by way of a pipe 3. The rate of flow of the water, and consequently the proportion of water to syrup in the dispensed liquid is predetermined by an adjustable screw 38 which partially closes a passage 37 through which the water flows from the conduit 27. To avoid drip after dispensing, a groove 25 connecting the delivery end of the passage 14 to the end of the passage 15 is provided so that suction induced in the passage 15 on closing movement of the valve 16 may withdraw syrup from the delivery nozzle. A fine port 26 is provided in the cover 24 to allow the pressure in the passage 15 gradually to be restored to full atmospheric pressure.
