Title: Recovery of energy from waste gas streams
Inventor: REEVE BRIAN ROBERT
IPC: F01K25/14
Filed: 1982-01-14
Abstract: In an iron- or steel-making plant a stream of waste gas at super- atmospheric pressure and elevated temperature issuing from a metallurgical processing vessel (1), is supplied through means (6, 12) to the inlet of a gas expander (16) to drive a rotor (18) and thereby an output drive shaft (22).

Title: Manufacture of polymer dispersions
IPC: C08J3/03
Filed: 1982-02-19
Abstract: Stable dispersions of halogen- containing addition polymers, such as polyvinylidene fluoride, in water- dilutable liquid media, for example 2- butoxyethanol and water are produced by dispersing pre-formed particles of the polymer, of a number-average size in the range 0.1-10 microns, in the liquid medium in the presence of a polymeric dispersant containing in the molecule a hydrophobic polymer chain and strongly ionised groups, in particular quaternary ammonium groups, the strongly ionised groups being present in such a proportion as to provide a charge density of from 0.05 to 6.0 milliequivalents per gram of the total dispersant. The dispersions thus obtained are valuable as a basis for water-borne coating compositions.

Title: Load indicator
Inventor: KIRK ANTHONY NOEL
IPC: G01L5/00
Filed: 1983-12-15
Abstract: A load indicator is used to indicate when the force applied to an electronic component to make good electrical and thermal connection thereto reaches a predetermined threshold value. The indicator is a snap action device 15 having two stable states, only one of which is available at loads above the threshold value. The indicator is fitted in a rigid member in the position shown in Fig. 3. Load is applied through the rigid member to a spring which contacts the tang 16 of the indicator. At the predetermined load, the deflection of the spring causes the indicator to snap with an audible "ping" to the second stable state shown in Fig. 2. Subsequent manual inspection may be made to check whether the load exceeds the threshold value by pressing the indicator in the direction 22. <IMAGE>

Title: Controlling glow plugs in an internal combustion engine
Inventor: LICER ALBIN
IPC: F02P19/02
Filed: 1985-06-28
Abstract: When a switch S is closed, a comparator 2 causes an astable multivibrator 4 to close a switch 8 thereby supplying power to glow plugs A and lighting a lamp 2. Eventually the voltage across a capacitor C2 equals a reference voltage UREF2 whereupon the comparator 2 causes the multivibrator 4 to switch off the power supply to the glow plugs and also turns off the lamp 2. The engine is ready to be started. When there is no current supply to the glow plugs, they act as thermocouples whose voltage is compared in a comparator 1 with a reference voltage UREF1 to keep the glow plug temperature at that necessary for igniting fuel. An engine temperature probe R5 connected to a comparator 3 turns off the power supply to the glow plugs when the voltage across a capacitor C3 equals a reference voltage UREF3. <IMAGE>

Abstract: The process for the obtention of dialkyl ethers of 3-oxo-butyl phosphonic acid provides for interacting dialkyl ethers of phosphorous acid with mesityl oxide in the presence of natrium alcoholate dissolved in lower alcohols. The mixture of dialkyl ether of phosphorous acid with mesityl oxide which are taken, respectively, in an amount of 1:1.4-2.0 mole parts and a solution of natrium alcoholate in lower alcohols are fed simultaneously into a reaction zone in two flows. Speeds of the flows are so selected that the mole ratio of dialkyl ether of phosphorous acid and natrium alcoholate is maintained, respectively, in the range of 1:0.16-0.20. The temperature held in the process ranges from 70 to 100<o>C. Said interaction results in the production of a reagent mass wherefrom an ultimate product is extracted.

Title: Solvent cleaning plants
Inventor: WEEMES GEOFFREY CHARLES
IPC: C23G5/04
Filed: 1986-05-02
Abstract: The rise in temperature of the boiling solvent in the sump of a solvent cleaning plant is monitored and used to indicate the condition of the solvent and the need to clean out the sump. The temperature of the solvent is monitored and a rise in temperature to a predetermined value or range of temperature indicates serious impairment of the ability of the solvent to clean articles satisfactorily, whereupon the sump is cleaned out. In a preferred embodiment of the invention the spent solvent is distilled within the cleaning plant until the temperature of the boiling residues in the sump rises to a second predetermined value or range of temperature whereupon the residues are removed and the sump is cleaned.
