Title: Improvements in or relating to the regulation of refrigerating apparatus
IPC: F25D21/02
Filed: 1936-07-07
Abstract: 467,773. Refrigerating. ELECTROLUX, Ltd. July 7, 1936, No. 18844. Convention date, July 10, 1935. [Class 29] The supply of heat or other energy to refrigerating-apparatus of a cabinet is cut off, to allow the evaporator or cooling unit 4 to defrost, by the action of a feeler member 13 which is brought into engagement with the cooling unit by the opening or closing movement of the cabinet door 3. The feeler member is only effective when ice has accumulated on the cooling unit. It is slidable on a sliding rod 6 urged into engagement with the door by a spring 11 in a casing 32. When the door is opened a pin 12 on the rod carries forward the feeler member against the action of a light spring 18, and a spring tongue 14 on the feeler engages ice on the part 15 of the cooling unit and is thereby flexed to grip a part 17 fixed to the cooling unit and to hold the feeler against return with the rod 6 when the door is closed. The feeler slides against a flat surface of a housing 21 of a thermal element 20 controlling the machine, and, when held by the friction of the ice layer, rapidly transmits cold to influence the thermal element to cut off the energy supply. The thermal element may be that normally used to maintain the appropriate temperature of the cabinet, and is insulated by an air gap from the evaporator when the feeler is not held by the ice layer. In place of a sliding rod a system of levers or a flexible wire may be used. The action of the feeler member may be temporarily disabled when rapid ice making or freezing is required in spite of the need for defrosting, by a locking device for the rod 6 actuable from the outside of the cabinet, and this may incorporate means for indicating whether or not defrosting is taking place. The sleeve surrounding the thermal element may be used as the feeler member, which may be frictionally held by ratchet ribs or other means on the evaporator. The invention is particularly applicable to heat-operated refrigerating apparatus without moving parts. The movement of the door may, however, serve to actuate the switch of a compressor driving motor. The Specification, as open to inspection under Sect. 91, comprises also the following : The movements of the door may be utilized to bring into position over the door opening a venetian blind screen to prevent loss of cold when the door is open. A bimetallic strip device may be used as a holding means for the feeler member. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to devices for measuring the content of paramagnetic gas in a gaseous mixture
IPC: G01N27/74
Filed: 1948-07-14
Abstract: <PICT:0674044/III/1> <PICT:0674044/III/2> A device for measuring the content of a paramagnetic gas, such as oxygen or nitric oxide in a gaseous mixture, comprises a test cell having a gas passage and a pair of chambers connected therewith each chamber containing an elongated heating element, means being provided for producing a magnetic field around the whole length of one of the heating elements.  In operation the paramagnetic gas is attracted towards the strongest part of the magnetic field, that is, towards the centrally placed heating element, thus becoming heated, losing its magnetic attraction, and being replaced by fresh gas.  The temperature of the heating element, lowered by the increased gas circulation is compared electrically with that of the element in the comparison chamber, the cooling being proportional to the paramagnetic gas content. According to the preferred embodiment, magnetizable pole pieces 24, Fig. 2, extend the whole length of chamber 18 and, due to their shape form a constriction within the chamber surrounding the centrally placed heater 36.  A magnet 28 is pivoted about an axis 32.  A companion chamber 20 identical with chamber 18 except that no magnetic field is applied, is provided, the heating elements in the two cells forming adjacent arms of a Wheatstone bridge circuit.
