Abstract: 1,050,618. Electric heating of pipes. ELECTRO-TRACE CORPORATION. Aug. 4, 1964 [July 26, 1963], No. 31051/64. Heading H5H. Pipes are heated by flexible strip elements 3 which extend along the pipe but are insufficiently wide to surround it, having bus-bars 3b along opposite longitudinal edges so that current flow is across the widths of the strip and terminal access is necessary at only one point 4. The element comprises a resistance layer embedded in a glass-asbestos fibre layer sandwiched between two layers of plastics insulating material and is secured by annular straps 5. Pipe and heater are covered with lagging 2. The heating is controlled by a thermostat 6 in contact with the pipe at the coldest part of the system. This may be specially provided such as a blanked-off branch pipe or an isolated pipe section (Figs. 4 and 5, not shown).

Abstract: 1,051,896. Magnetic switches. FICHTEL & SACHS A.G. June 4, 1964 [June 6. 1963], No. 23264/64. Heading H2B. A contact-breaker controlling the ignition circuit of an internal-combustion engine comprises a sealed housing 32 enclosing a magnetic contact blade 46 carrying a contact 48 biased by the resilience of the blade into engagement with a fixed contact 44. The contact-breaker is opened periodically by a permanent magnet, or magnets 30 carried by the fly-wheel or fanwheel of the internal combustion engine. The housing 32 may be provided with plug-in connections. In an alternative arrangement (Figs 6 and 7, not shown), a permanent magnet is arranged in the wall of the housing and the major portion of the periphery of the fly-wheel is magnetic. Whilst the magnetic part of the fly-wheel is adjacent the contact breaker it shunts the flux away from the magnetic contact blade which therefore remains closed, but as soon as the gap in the magnetic periphery comes opposite the contactbreaker, the permanent magnet attracts the contact-blade to open the contacts.

IPC: A47J27/21
Abstract: 1,052,637. Control systems for heating elements; thermal switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 5, 1963 [Sept. 5, 1962]. No. 34045/62. Headings H2B and H2H. Control systems for heating elements.-The heating element 2 of an electric kettle is connected to a supply 14, 25 through parallelconnected contacts 6, 7 and 9, 11, the contacts 7, 11 being respectively carried by a low resistance conductor 18 and a high resistance bimetal strip 8. For rapid heating from the cold condition both contact pairs are closed and a large current flows through the conductor 18. Upon a predetermined water temperature being reached, another bimetal strip 4 opens contacts 6. 7 thereby producing reduced current flow through the bimetal strip 8 which thereafter cycles the contacts 9, 11 to maintain the water at a higher predetermined temperature, e.g. boiling. These temperature settings may be varied by adjustment of the strips 4, 8, and should the kettle boil dry the strip 4 may be arranged to interrupt or reduce the current by permanently opening the contacts 9, 11 or varying the operating cycle of the strip 8. Thermal switches.-The heater element 2 of an electric kettle 1 is controlled by a thermal switch comprising adjustable bimetal strips 4, 8 respectively responsive to the water temperature and to the heater current, the strip 8 having a high resistance and being carried by a rigid low resistance conductor 18 which is connected through a conductor 19 to the element 2 and carries a contact 7 co-operating with a contact 6. This contact is mounted on a resilient conductor 12 connected to a kettle terminal 14 and having an insulating end 16 co-operating with the strip 4. Members 8, 12 carry contacts 11, 9 which operate with a snap action due to the effect of a magnet 21 and an armature 22. In operation both contact pairs are initially closed until contacts 6, 7 are opened by movement of the strip 4, the contacts 9, 11 remaining closed due to the effect of members 21, 22 and to bias in the strip 8. Thereafter contacts 9, 11 are cyclically opened and closed by the strip 8, provision being made for the strip 4 to permanently open these contacts or to vary the operating cycle of the strip 8, should the kettle boil dry.

IPC: H01L35/00
Abstract: 1,054,739. Gas turbine engines. L. HUBER. Sept. 14, 1965 [Oct. 14, 1964], No.39210/65. Heading F1G. [Also in Division H1] A thermoelectric generator comprises a plurality of thermocouple elements 11 the hot junctions 15 of which are disposed in a surface which surrounds but does not engage an oscillating column combustion chamber 1, 4. Combustion gases are fed by the end 5 of the coil 4 to a radial turbine 6 and pass through a first silencer 8 and pipe 9 to a second silencer 41, Fig. 4 (not shown), which exhausts through a coiled tube 45 leading to an ejector 47. The reduced pressure produced by the ejector may be employed to evacuate the interior of the ceramic jacket 10, in which the thermocouple elements 11 are mounted, or to evacuate the labyrinth packing 30 of the turbine, pipes 26, 29 being provided for this purpose. Alternatively, as shown, the pipes 26, 29 may be connected to the reduced pressure region inside a cap 28 housing the air intake valve 2 of the combustion chamber. Outside air enters this region through bores 28b, 28c, and the air inlet can be throttled by rotating the cap 28 so that the magnitude of the reduced pressure can be controlled. If large leaks develop in the combustion chamber the exhaust gases entering the cap 28 via the pipes 26, 27 will disturb the air-to-fuel ratio in the chamber and combustion will be extinguished. The turbine 6 drives an impeller 22 which blows air through the space between the ceramic jacket 10 and an outer pipe 25 where it flows over cooling vanes 17 attached to the cold junctions of the thermocouples. The air subsequently flows over the second silencer 41 and the coiled tube 45 and may thereafter be used for space heating.

Abstract: 1,226,432. Valves. SOC. ANON. FRANCAISE DU FERODO. 4 Oct., 1968 [6 Oct., 1967], No. 47098/68. Heading F2V. A three-way cock comprises two annular valve seats 14, 15 by means of which two ducts 13, 12 may be respectively brought into communication with a third duct 11 (dashed lines) of inlet pipe 1, and wherein the cock control means comprises a flexible member 16 whose contact surface 23 can bear against one seat 14 whilst being free from the other. In operation, fluid flowing in inlet chamber 1 passes through an inlet 11 of the valve into an annular chamber 8. With the member 16 in its lowermost position, the valve seat 15 is closed. On raising the member slightly, fluid has access to an annular chamber 9 in communication with an outlet 12 but is prevented from flowing to chamber 10 by the closed valve seat 14. Further raising of the member 16 permits an increased flow of fluid to outlet 12 and allows fluid to communicate with outlet 13 via chamber 10. In another arrangement, chamber 10 is offset towards the outlet 13. In an alternative arrangement, the contact surface (23b), Fig. 5 (not shown), has a plane surface, the plane of the valve seats being at different levels. In this case the inlet pipe (10b) is directed parallel to the axis X-X<SP>1</SP>.

Conduction of thyristor 68 energizes a relay coil 72 closing a contact 76 in series with heater 14. The combination of resistors 66, 61 form a unit 67 of slow thermal response which acts as an integrator so that the instantaneous resistance of resistor 61 provides a measure of the mean current flowing through the heater 14. The relay coil may be replaced by a resistor and the contact 76 by a triac or a pair of reverse parallel thyristors.
