IPC: F24F11/00
Filed: 1964-07-29
Abstract: 1,020,560. Automatic control of environment. INSTRUMENTATION SPECIALITIES CO. July 29, 1964, No. 30108/64. Heading G3R. In a system for controlling a condition the levels of two variable factors are sensed to provide signals when the levels are above or below preselected levels, means being provided to convert the signals into discrete outputs voltages in correspondence with the directional deviation of the variable factors which are employed to actuate one or more control elements to effect a change in level of the interacting variable factors. The temperature and humidity of an environmental chamber are controlled by a system responsive to the outputs of a wet and a dry thermistor temperature sensing devices. The air in the chamber is circulated by fans over heating and cooling coils and across a water-bath, varying the humidity, containing heating and cooling coils. The control system, as shown, comprises bridges 30, 31 having arms adjustable 33, 35 to desired dry and wet temperatures and arms 23, 24 comprising wet and dry bulb thermistors respectively. The D.C. signals from the bridges are fed to amplifiers 37, 38 having alternating outputs of positive phase when the temperatures are high and of negative phase when the temperatures are low. The outputs are combined by a subtractive resistance arrangement 41 to provide a humidity dependent output of positive phase when the air is too dry and of negative phase when the air is too humid. The outputs of amplifier 37 and arrangement 41 are fed to interconnected triodes 103, 104 and 105, 106 respectively which conduct for the temperature or humidity criteria indicated to selectively actuate relays 44-47. The contacts of the relays determine the inputs to a diode matrix 48 determining the combination of control elements 20, 12,18, 16a, 16b to be energized. The low and high water heating rates are determined by energizing a heater intermittently or continuously through a motorised switched arrangement see Fig. 4, not shown.

Controlling arrangements for collectors.-The pressure of a spring-supported bow collector 4 is made uniform on both sides of the vertical position by arranging, between the fixed end of the spring and the lever arm 6, a stationary supporting-point over which the spring action is transmitted to the arm. The spring may be connected to the arm bv a chain which runs between fixed rollers defining the supporting point, or the spring may be carried in a cradle pivoted to the base 1. In a modification, Fig. 3, the spring 2 is connected to a bell-crank 16 and rod or chain 13, or cam discs 15, 17, 18 are used. The Specification as open to inspection under Sect. 91 (3) (a) states also that in existing bows, the bow axis 3, Fig. 1 (Cancelled), the end of the arm 6 and the fixed point 5 of the spring 2 are arranged in line when the bow is vertical.

Abstract: 280,582. Soc. Anon. des Manufactures des Glaces et Produits Chimiques de St.-Gobain, Ghauny, et Cirey. Nov. 15, 1926, [Convention date]. Rolling.- Relates to the method of making sheet glass in which a stream of molten glass, issuing from a horizontal slot in the wall of a tank or forehearth, flows into the pass between parallel rollers and is formed into a continuous strip. According to the invention, the glass in the forehearth where it flows through the slot is maintained at a temperature above that at which devitrification is liable to occur, and the issuing glass is cooled rapidly, to a temperature suitable for the rolling operation, by more or less prolonged contact with the air and with walls which are more or less conducting. This cooling is preferably effected by causing the issuing glass to pass into an exterior reservoir G formed by a floor slab H and side walls, as described in Specification 253,866, its floor forming a prolongation of the bottom lip of the slot B. Cover strips J rest on the side walls and project an adjustable distance over the surface of the glass to maintain the margins of the stream at a temperature equal to or above that of the central portion. A block O, placed in contact with the slab H, is formed with a cavity P to which a gas flame is supplied to regulate the temperature of the slab H. Specifications 241,206 and 241,207 are referred to.

Title: Improvements in or relating to the manufacture of alloy steel
IPC: C21C7/00
Filed: 1919-12-08
Abstract: 164,394. Hadfield, Sir R. A. Dec. 8, 1919. Alloys.-Nickel-chromium steel scrap is remelted in a basic open-hearth furnace with carbon and lime in order to obtain high-grade nickel-chromium steel practically free from phosphorus and sulphur. The charge is melted with carbon and lime, and iron oxide such as mill scale and fluorspar may be added to render the slag fusible. The slag is removed and the melt further refined with lime and iron oxide additions, and brought to the boil. After the carbon content has been reduced to about 0.3 per cent, and the phosphorus to a trace, the slag is again removed and the boil is stopped by the addition of ferro-silicon or other deoxidant. The melt is again covered with lime to eliminate as far as possible the sulphur remaining, and the final composition of the steel is adjusted before casting; or the melt may be finished in an electric furnace with lime and anthracite, and the final alloying additions made in the furnace or in a casting ladle. In a modification, the elimination of sulphur is facilitated by adding manganese steep scrap to the original charge.
