Title: Using otherwise wasted thermal energy from engines
Inventor: STACEY JONATHAN LEE
IPC: B60K6/20
Filed: 2008-10-16
Abstract: Engines can never be 100% efficient and some waste thermal energy is always produced that needs to be removed from the engine and is currently dumped into the Earth's biosphere. This invention relates to systems for capturing, storing, transporting and utilising the unused thermal energy produced in engines. For example, having cooled a ship's engine, fig.1, the liquid coolant, eg sea water, may be stored in insulated tanks 7 for removal and transfer for sale or use. The cooling liquid may be taken from on-board tank(s) (11,16, figs.2,3). A road or rail transport vehicle, fig.4, may have a storage tank 11 filled initially with cool liquid 13 which passes through the engine 5 and is stored as hot liquid 14 in an insulated tank 7. Alternatively, cool liquid may be taken from and returned as hot liquid to a single tank (16, fig.5). An i.c. engine/electric hybrid vehicle may be connected, when stationary, to a storage tank (16,fig.6) which receives hot fluid from the engine. Electricity generated in the vehicle is stored in batteries (36) and/or transferred to a remote location via wires (41). Instead of large power station(s), each house (52,fig.8) may have a parked car (53) which forms part of a combined heat and power (CHP) system or a tri-generation system for a number of houses.

Abstract: 473,338. Sterilizing chambers and processes. ALCOCK, A. U. April 7, 1936, No. 10254. [Class 81 (i)] Sterilizing - apparatus comprises a treatment chamber, exhausting means therefor, automatic means to put the exhauster out of action when a predetermined vacuum has been attained, means to vaporize and supply a disinfectant such as formaldehyde to the chamber, and air admission means to restore the chamber to atmospheric pressure. In the form shown in Fig. 1, the chamber 1, connected by a pipe 9 to exhaust pump 8 driven by an electric motor 8a, is formed with an absorbent lining, an absorbent perforated false bottom 4, and an air and vapour inlet passage 2 connected through an electrically heated vapour generator 23, and a U-shaped pipe 18 to an air inlet valve 21a controlled by a solenoid 22. The base of the chamber 1 is fitted with an electric heating resistance. A corrugated metal bellows 10, Figs. 1 and 5, carrying electric contacts 13a, 13b adapted to engage fixed contacts 14, 15, is connected to the exhaust pipe 9 so that as the chamber 1 is exhausted the bellows will collapse and, through the fixed and moving contacts, operate an electromagnetically controlled switch to cut out the motor 8a. The bellows also controls the solenoid 22 operating the valve 21a. During the whole period of treatment a slow trickle of air passes through an adjustable valve 19, pipe 18a and the vaporizer 23 into the chamber, but when the vacuum in the chamber has been reduced to a predetermined extent, after stopping the motor, the solenoid 22 is energized to open the valve 21a so that a rapid inflow of air takes place. The pipe 18 is connected to a reservoir 17 for liquid disinfectant so that the lower part of the pipe becomes charged with disinfectant which is transferred to the vaporizer 23, when the air inlet valve 21a is opened. Modified constructions of the pipe 18 and reservoir 17 are described and in a further modification the reservoir 17 is dispensed with, the vaporizer being charged with a solid vaporizable disinfectant. A second bellows control may also be provided to control separately the heating coil 24 of the vaporizer 23. Various arrangements of the electric circuits are described whereby the order in which the various heaters, the motor, and the various controls are energized or de-energized may be varied. Coloured lamps are provided in various portions of the circuit to act as indicators.

Title: Colouring stainless steel
Inventor: JAMES HOWARD
IPC: C23C22/24
Filed: 1966-03-09
Abstract: Nickel-containing stainless steel is coloured gold by immersion in an aqueous solution of chromic and sulphuric acids, and blue or red by first forming a gold colouring end then heating the coloured steel in air at from 300 DEG C. to 700 DEG C. preferably around 550 DEG C. until it reaches the desired colour.  Resists may be employed to provide designs or lettering, and can be used repeatedly, with protection of colours already formed, to make combined patterns of different colours.  Known gold colourings may be obtained in aqueous solution containing between 50 and 1000 grams/litre of CrO3, with a considerable variation in their appearance and in the time taken to form them, but the dark gold colour of the invention is obtained with a solution containing from 520 to 580 grams/litre of chromic acid and enough sulphuric acid to make the ratio of the weights of chromic acid to sulphate iron present between 3:1 and 7:1, at 65 DEG C. to 75 DEG C.  The concentrations of chromic acid and sulphuric acid are preferably respectively 550 grams/litre and 60 ml/litre, using sulphuric acid with an S.G. of 1.84, and the working temperature is 70 DEG C.  The concentration of trivalent chromium ions is kept below 10 grams/litre by electrolysing the solution continuously between a large anode and a small cathode, preferably in a subsidiary tank through which the solution is circulated.  Manganous sulphate may be added to the solution to enhance the colouring of the steel.
