Patent GB-185143-A (GB)
Abstract: 185,143. Gall, G. J. March 2, 1921. Regulating; valves; valve-gear.-An engine having a piston of two diameters draws in below it, through a flat suction-operated valve 6, a charge of air which is forced through a non- return valve 9 into the interior of the piston during its out-stroke. A separate charge of air is drawn into the annular pump space and is transferred to the interior of the piston through valves 8 having controlling-springs 8<a> arranged as shown in Fig. 1. The air charges enter the combustion space through non-return valves 7. The outlets for burnt gases are controlled by a pair of valves 21 actuated through levers 20 secured to rods 19<a> carrying pistons 19<c>. At the end of the out-stroke of the working piston, gases escape through a passage 1<b> and past a non-return valve 18 to ports 19<b> leading to the undersides of the valve-actuating pistons 19<c>. The ports 19<b> are controlled by a piston valve 17 which is raised by a piston 14 acted upon by the pressure in the air-pump 2. The piston 14 is returned by a spring 15, the tension of which may be adjusted by a nut 15<b>.

Patent GB-1535026-A (GB)
Title: Method of heating a building and of supplying hot water thereto
IPC: F24V50/00
Filed: 1977-05-04
Abstract: The method uses fossil primary energy via an additional heating system (17), solar energy via a solar collector (12) and environmental heat via an air heat exchanger (13). These energy sources take over, individually or in combination, according to the quantity of energy arising, the heat supply. The method also makes use of a heat pump (16) and a heat accumulator (15), e.g. a latent-heat accumulator. The heat accumulator (15) is charged by the solar collector (12) when a surplus of solar energy is available, or when, in the case of incapacity of the solar collector (12) for direct heating, the heat requirement is covered by the heat pump (16), where appropriate together with the additional heating system (17). The additional heating system (17) which consumes the fossil primary energy is only switched in when the heat requirement cannot be covered by the solar energy, the environmental energy and the energy stored in the heat accumulator (15), where appropriate with interconnection of the heat pump (16). As a result, it is possible to limit the consumption of fossil energy. <IMAGE>

Abstract: 363,617. Directive wireless signalling. ROSE, R. L. SMITH- and THOMAS, H. A., National Physical Laboratory, Tuddington, Middlesex. June 21, 1930, No. 19028. [Class 40 (v).] A wireless beacon transmitter comprises two pairs of spaced vertical aerials A B, C D, Fig. 2, each having a vertical radiating portion fed from a goniometer or like device by means of pairs of horizontal or inclined non-radiating leads F, Fl, the current distribution .in which is balanced by inserting a coil LA .. LD in each vertical portion. The wires F, F<1> of each pair are arranged side by side in a horizontal or vertical plane, and they may be crossed at intervals. The aerials A .. D may be formed as metallic masts, and the auxiliary coils LA .. LD may be adjusted by insulated rods. The aerials A, B forming an opposite pair may be connected to rotating goniometer coils LA, LB, Fig. 5, which are small in dimensions compared with the stator coils LS<1>, LS<2> connected to the transmitter. A similar arrangement supplies current to the other two aerials, the two sets of primary coils being in series, and the rotating secondaries geared off the same shaft, which may be rotated by a motor with tuning-fork control. Each goniometer section is enclosed in a separate screening-box, as is also each stage of the transmitter, whilst the room in which the apparatus is housed is also screened, with the object of confining radiation to the vertical aerials. The two-section goniometer may be connected at a low-power stage of the transmitter, and separate amplifiers inserted between the goniometer and the aerial couplings. Such an arrangement is illustrated in Fig. 7, in which, however, the goniometer is replaced by a resistance C connected across the high-frequency source G, the leads to the separate amplifiers 1, 2 being connected to sliders A, B which are given a simple harmonic motion along the resistance C and are arranged to give voltages 90‹ out of phase.

Abstract: 510,047. Filtering liquids. ATLASAGO CHEMISCHE FABRIK AKT.-GES. June 27, 1938, No. 19059. Convention date, June 26, 1937. [Class 46] Liquid is filtered by being fed to a gap between the peripheries of two bodies which rotate in the same sense, the liquid passing through the gap while the impurities are retained. In the construction shown in Fig. 1, a tank 1 is closed by a pair of rolls 3, 4 rotatably mounted and spaced apart by a narrow gap 5. The rolls rotate as indicated by the arrows, the roll 4 rotating at a greater speed than the roll 3. Impurities are drawn up by the roll 4, scraped off the roll by a scraper 9 and collect behind a guide plate 12 and a perforated partition 14. A second guide plate 11 operates to distribute the liquid on the surface of roll 3. The filtered liquid is scraped from the roll 3 and collected in a tank 6. In the construction shown in Fig. 2, a series of rolls is employed with a small gap between each pair of adjoining rolls. The purified liquid collects in a container 133 and the impurities are transferred from roll to roll, finally being discharged into a compartment 139. The Specification as open to inspection under Sect. 91 comprises also other forms of construction. In a modification of the arrangement shown in Fig. 1, the impurities are caught between parallel rotary discs and are delivered to a container located at the top of the tank 1. In the construction shown in Fig. 7 (Cancelled), plates 61 separated by spacing members 62 are mounted on shafts 63, 65 and form a zig-zag gap for the passage of the filtered liquid. In a further construction shown in Fig. 12 (Cancelled), a casing 121 contains five rolls 125, each consisting of spaced plates adapted to trap impurities while the filtered liquid flows into a sump 123. The impurities are carried from roll to roll and are removed. by a scraper 127. Scraper blades 129 remove filtered liquid from between the plates. Somewhat similar filtering arrangements employing one and two laminated rolls are also described. This subjectmatter does not appear in the Specification as accepted.
