Title: Improvements in snap-action mechanisms
IPC: F16H35/14
Filed: 1951-02-13
Abstract: 686,730. Snap action retractive switches. MINNEAPOLIS-HONEYWELL REGULATOR CO. Feb. 13, 1951 [April 17, 1950], No. 3531/51. Class 38 (v) [Also in Group XXXII] In a snap-action mechanism having a resilient elongated tension member mounted in cantilver fashion and held in tension by a compression member, the tension member has its cross-sectional area reduced over a region close to its mounting so as to increase its flexibility. In the arrangement shown, a unitary blade spring has outer bowed compression members 16 pivotally supported in grooves at the ends of legs 23 of a U-shaped fixed plate 24, and a central elongated tension member 17 with its fixed end secured in a recess 42 in the plate 24 by a screw (not shown). A hole 55 is provided in the member 17 to reduce its cross-sectional area and so increase its flexibility. This increase in flexibility is stated to increase the working life of the mechanism. As applied to a snap-action switch, Fig. 1 (not shown), the spring blade is provided with a contact 41 which cooperates with fixed contacts (not shown) and a push button is arranged to engage the tension member 17 at a point between the mounting and the axis of the pivotal supports of the compression members 16.

Title: Window Structure
Inventor: MECKLER GERSHON
IPC: F24F5/00
Filed: 1966-08-19
Abstract: 1,169,556. Multiglazed units. LITHONIA LIGHTING Inc. 19 Aug., 1966, No. 3543/69. Divided out of 1169555. Heading E1R. [Also in Division H1] The specification relates to heat absorbing windows for air-conditioned buildings. Fig. 1 (not shown) illustrates part of a building with concrete floor containing air conditioning ducts (outlet 25) and the heat absorbing windows 20. Each window, at ceiling level, is connected to a first stage cooling circuit by ducts 27, 28 (typical operating temperature 65-75‹F) and, at floor level, is connected to a second stage circuit by ducts 30, 31 (T= 85-90‹F). Fig. 2 shows a window 20 with outward facing glass 33 and similar inward facing panel 35. The inner panel 75 is cooled by a cascade 2-stage Peltier cooler the sections of which are electrically in parallel. Heat is rejected at junctions 50 to a series of spaced copper strips 39 which terminate in fins 46 immersed in the first stage coolant. The cooler may be energised via conductor 49, 57 by a Seebeck generator structurally carried by a panel 32 of I.R. absorbing glass in the centre of the window. The absorbing junctions 43' of the generator may be blackened for more efficient operation. Heat from the generator is rejected to a metallic film 52 which also receives heat for the I.R. absorbent panel 32. This heat is rejected to the second stage coolant via fins 54. An A.C. energised heater 58 is provided on the inside of the outer panel for occasions when the light-heat input to the generator is inadequate. An electroluminescent film and a photo-conductive film may replace the heater to give supplemental heat and to modify the light through the window. To avoid using the heater with the consequent risk of bending the window, D.C. may be fed to the leads, between the Peltier and Seebeck devices (in parallel with the generator output). The I.R. absorbing panel 32 in the centre of the window divides the structure into two zones; the air space 34 between the panel 32 and the outer panel 33 may reach a temperature of 200‹F whereas the air space 36 between the center and inner panels 32, 35 is cooler, the interior of the inner panel being kept at 75‹F.

Title: A process and apparatus for complete liquid and vapour phase oxidation of organic material with the production of high enthalpy vapour
IPC: F01K3/18
Filed: 1956-02-07
Abstract: 809,604. Treating sewage. STERLING DRUG Inc. Feb. 7, 1956 [Feb. 9, 1955], No. 3831/56. Class 111. [Also in Group XIII] Steam present in the effluent gases and vapours generated during a process for the partial combustion at high pressure and in the aqueous phase of finely comminuted carbonaceous waste matter, such as garbage or sewage or industrial waste such as pulping liquor, is superheated so that it may be economically used for power generation by controlling the aqueous phase reaction which takes place in a zone 11 so that the reactor effluent contains from 0.1 to 5 per cent. of unoxidized combustible material and sufficient free-oxygen-containing gas to satisfy the oxygen demand of this material. Liquid is removed from the effluent in a separator 12 and the vapour effluent from the separator passed into a heat exchanger 13 wherein its temperature is raised by indirect contact with at least some of the freshly formed superheated vapour to the ignition temperature of the combustibles. The ensuing vapour-phase exothermic oxidation which occurs in a zone 14 downstream of the heat exchanger causes superheating of the steam which flows, together with the fixed gases present, through the heat exchanger 13 in indirect contact with the incoming effluent to a turbine 15. The partial aqueous phase oxidation may be achieved by suitably controlling the complete oxidation process described in Specification 706,686 preferably by restricting the amount of free oxygen-containing gas supplied to the reactor to give the effluent vapour the required fuel value, in which case the required amount of oxygen is added to the vapour effluent, or by regulating the temperature and pressure conditions in the reactor or the residence time therein of the reactants to give the required amount of both fuel and oxygen in the effluent. If the quantity of superheated steam and fixed gases is in excess of that required to heat the incoming effluent sufficiently to render the process selfsustaining, the surplus passes directly to the turbine through a by-pass BP. To start the vapour phase reaction a heater 16 in the zone 14 is used to raise the temperature of the gases from the first reaction zone 11 to the combustion point of the entrained combustibles, the heater being turned off as soon as sufficient exothermic heat becomes available to sustain the final oxidation reaction. In a modification, the zone 14 contains catalysts such as stainless steel, silica gel, metals or metallic oxides which are effective to lower the combustion temperature of the entrained fuel. To give the vapours a higher degree of superheat a gaseous fuel such as methane may be injected into the effluent from the aqueous phase oxidation zone.
