Title: Heat-meter system
IPC: G01K17/10
Filed: 1955-02-21
Abstract: 765,324. Measuring heat quantities. NILSSON, R. Feb. 21, 1955, No. 5117/55. Class 97(3) In a heat-meter system, a source of heat is included in a circulation system for a heat-conveying fluid, and this circulation system is connected to one or more heat exchangers from which heat for consumption is drawn, the or each heat exchanger being associated with a temperature-responsive valve which maintains a substantially constant temperature difference between fluid entering and leaving the or each heat exchanger and with a meter measuring the amount of fluid flow. As shown, the feed and return pipes 1, 2 of a hot water circulation system are connected to the inlet and outlet conduits 3, 4 of a heat-exchanger comprising a vessel 5 holding a large quantity of water and having a height at least twice its width. A coil 6 in vessel 5 communicates e.g. with radiators through conduits. 6a, 6b. A temperature-responsive element 9 near outlet conduit 4 operates a valve 10 in the conduit, to open it when the temperature near the outlet falls below a minimum amount, and to close it when the temperature rises to a maximum amount. The quantity of hot water passing through the vessel 5, which is nearly proportional to the amount of heat supplied, is measured by means of a meter 11. If the temperature of the hot water supply is not sufficiently constant, the valve 10 may be connected (as shown by the dotted line 12) to a temperatureresponsive element 13 in the feed pipe 1. The arrangement is such that the valve is operated by the difference in temperature at the elements 9, 13. Hot water supply systems incorporating the arrangement are described. Hot water may be drawn off directly from the vessel 5; in this case coil 6 may be omitted, and conduits 6a, 6b lead directly into and out of vessel 5. The amount of hot water drawn off, and possibly also the amount of cold water supplied, may be metered.

Title: Improvements in or relating to fuel injection systems for diesel and like engines
IPC: F02M57/02
Filed: 1955-02-21
Abstract: 795,350. Fuel - injection systems; valves. SIMMS MOTOR UNITS, Ltd., and DUNN, H. G. Feb. 21, 1956 [Feb. 21, 1955], No. 5156/55. Class 7(3) and 7(6) In a multi-cylinder engine a pump 13, closely associated with each injector 12, circulates fuel through passages 25, 27, in the injector to a by-pass pipe 32 ... 35, Fig. 2, leading to the fuel reservoir, injection occurring when the by-pass pipes are temporarily blocked in sequence by a rotary control valve. In Fig. 2 the by-pass pipes 32...35 of separate injectors each having an injection pump 13 formed therewith as a unit, are connected to ports 46 controlled by a rotating valve 39 having an annular recess 47 therein connected by passages 48, 49 to a return pipe 54 leading to the reservoir, a raised land 53 serving to block each port 46 in succession at the required moment for injection. The valve 39 is splined to a drive shaft 37 and the land 53 is wedge shaped to vary the period of injection when the valve 39 is moved axially by a yoke 41 controlled by a governor. The pumps 13 are supplied by a low pressure feed pump and each by-pass pipe 32...35 contains a non-return valve 29. The circulation of fuel through the passages 25, 27 cools the injector. In a four-stroke engine each pump plunger preferably makes one delivery stroke for each two revolutions of the engine; alternatively each plunger may make a delivery stroke for each engine revolution, alternate strokes serving only to circulate fuel through the injector and not producing injection. It is stated in the Provisional Specfication that a single pump may replace the separate injector pumps 13.

Abstract: 683,221. Half-sleeves for pipes. FIBREGLASS, Ltd. Feb. 2 1951 [March 1, 1950], No. 5158/50. Class 87(i) A thermal-insulation covering material, to be used particularly above 400‹C and for covering pipes, has an inner layer of a relatively high density and an outer layer of relatively low density. Moreover, the inner layer is made from bonded mineral wool or exfoliated vermiculite and the outer layer is made from bonded glass fibres. Mineral wool or exfoliated vermiculite with a sodium silicate or quick-setting cement binder is placed in thin layers on a mandrel. Around this mass is wrapped a mass of glass fibres bonded with starch and the resulting material is cut into sections to be applied to a pipe. Alternatively, a mass of bonded glass fibres is wound on a larger mandrel and the mass split into two or more parts after drying. The denser material is then sprayed on to the inner sides of these parts and while this is still plastic, the parts are allowed to set on a pipe-sized mandrel.
