Filed: 1974-01-14
Abstract: 1417821 Incinerator AIR PREHEATER CO Inc 14 Jan 1974 [16 Jan 1973] 01747/74 Heading F4B An incinerator has a primary chamber 12 above a second chamber 38 separated by a movable closure 36 that is opened by an actuator 42 to permit material to slide from the primary chamber into the secondary chamber. An outlet 16 from the primary chamber connects with an after burner 22 with fuel supply 34 and air supply 32. The chambers normally operate in series. Waste material is fed through loading door 14 and is initially burnt in chamber 12 by application of heat from fuel supply 55 and air supply 29. Incompletely burned residual matter is dumped into chamber 38 and limited combustion is maintained by fuel source 37 and air supply 35. Gas from chamber 38 may be selectively directed back to chamber 12 or to the after burner 22 by operation of valves 45 and 47 in duct 44. Large particles of ash are removed via collector 51. Chamber 38 may be isolated by closing valves 39, 41 and 45, 47 and a water spray 58 may be used to lower the temperature before removal of ash from door 43.

Title: Manufacture of artificial fibres from protein material
IPC: D01F4/00
Filed: 1939-01-21
Abstract: 524,090. Artificial filaments, bristles &e. albumens. TRAILL, D., SEDDON, R. V., SEVER, W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 21, 1939, Nos. 2150 and 18569. [Classes 2 (ii) and 2 (iii)] Artificial filaments, including bristles, are obtained by extrusion into a coagulating bath of a thixotropic viscous solution which has been made by maintaining at a temperature not below about 60 ‹C. a dispersion of ground-nut protein in dilute aqueous ammonia until an increase in natural viscosity at least of the order of 5-fold has been obtained. The protein content of the dispersion may be 10-25 per cent. and the ammonia concentration may be 0.5-1.0 per cent. The thermal treatment may be such that the viscosity attained is the same as that attained after 2.5-3.0 hours heating at 70‹C. The viscosity of the hot viscous solution or jelly obtained by the heat treatment may be reduced by a mechanical shearing treatment, and a similar treatment may be applied during the heat treatment to avoid the formation of a jelly. Dispersion of the protein in the aqueous ammonia may be assisted by mechanical homogenization and by warming to a temperature below 60 ‹C. The mechanical shearing may be effected by means of a colloid mill, emulsifier, or homogeniser. The temperature of extrusion is not necessarily the same as that of the heat treatment. The coagulating liquid may be a solution of sulphuric acid with or without sodium or ammonium sulphate. The fibres produced may be subjected to treatment with formaldehyde or other hardening agent and to treatment to increase their resistance to damage by wet treatment liquids. In an example, a heat treated ground-nut protein dispersion is cooled, aged, and spun into sulphuric acid solution. The thread is drawn without tension from the bath, then passed into formaldehyde solution and over stretching rolls. It is washed, dried, and cut into bristles. These are soaked in a solution of thionyl chloride in carbon tetrachloride. In another example, the thread after treatment with formaldehyde and drying is cut to bristles and these are soaked in saturated brine containing formaldehyde and hydrochloric acid. In another example, a ground-nut protein dispersion in ammonia solution is passed into a circulating device comprising an open reservoir, a constant delivery pump, a tube or jet type of homogeniser, a heating coil and a manometer attached to a conduit leading to the reservoir. The viscosity of the moving liquid is approximately a linear function of the pressure recorded by the manometer. The dispersion is first circulated for some time without heating. The homogeniser, heating coil and reservoir are then heated by means of hot water, and the circulation is continued until the desired increase in viscosity is attained. The cooled solution is extruded into a salt-acid bath and the filaments are wound at high speed. Specifications 492,677, 492,895, 495,332, 513,896 and 513,910 are referred to.

Title: Improvements in or relating to electrical resistance thermometers
IPC: G01K7/20
Filed: 1926-01-27
Abstract: 271,921. Bursill, A., and Electroflo Meters Co., Ltd. Jan. 27, 1926. Thermometers.-An electric resistance thermometer operating with alternating current comprises a coil 9 moving in the field of an alternating current electromagnet 11 and carrying a deflecting current controlled by a temperature responsive resistance 1 and also having induced in it a current which provides a voltage-compensated control. The moving coil 9 is so connected to the .electromagnet that a definite phase relationship exists between the deflecting current in the moving coil and the exciting current of the electromagnet. The temperature-responsive resistance 1 forms one arm of a Wheatstone bridge, the ratio arms 2, 3 of which are preferably equal and low in comparison with the thermometer resistance, the third arm 4 being adjustable. The bridge element is formed by the moving coil 9. In order to maintain the desired phase relationships the bridge system is connected, either directly or through a transformer 7, in series with the exciting coils 5 of the electromagnet 11. When the bridge is balanced, the moving coil 9 is in its symmetrical position in which no flux is linked with its turns. When the bridge is unbalanced the coil 9 is deflected from its symmetrical position and becomes interlinked with the alternating magnetic flux, an electromotive force depending on the deflection of the coil being thereby induced in it. An adjustable choking coil 12 is arranged in parallel with the coil 9 so that the induced current has a lagging component which produces a torque tending to restore the coil to its symmetrical position. In a modification the ratio arms 2, 3 are omitted, their place being taken by the secondary winding 6 of the transformer 7, which is tapped at its central point. The length of scale corresponding to a given resistance variation may be adjusted by varying the inductance of the choking coil 12, adjustment of zero being effected by varying the resistance 4. Weak springs may be provided to give sufficient control to centre the pointer when the instrument is disconnected. The current transformer. bridge resistance, and choking coil are preferably enclosed in the instrument casing.

A loop of auxiliary weft is inserted into the edge of the fabric by a needle which reciprocates in a straight line. To retain the loop whilst the needle withdraws from the shed, a pin 35a descends through the warp into the loop; the end of the pin is rearwardly inclined so as to move the forward limb 10 of the loop towards the fell, thereby enabling the vertical part of the pin to be positioned forward of the path of the needle. The pin is carried by an arm 35 pivoting about a warp wise axis. The auxiliary weft inserting needle is reciprocated by a cam and, in turn, operates the retaining pin 35a through a lost motion connection so that the pin moves only when the needle is near the ends of its stroke. These may be a selvedge mechanism at both edges of the fabric.
