Abstract: Water soluble condensation products are prepared by pretreating urea type compounds with ammonia type compounds at elevated temperatures, preferably between 80 DEG  and 100 DEG  C., and in the absence of aldehydes and condensing the product with aldehydes under acid conditions.  The urea type compounds are of formula <FORM:0679758/IV (a)/1> where R1 is an oxygen or sulphur atom or an imino group and R2 and R3 each represent a hydrogen atom, an alkyl, alkenyl, aryl or aralkyl group or an acyl radical derived from a saturated or unsaturated acid.  Specified are urea and its N-mono-alkyl or N-mono-aryl substitution compounds, thiourea and its derivatives, acrylol-urea or acrylol-thiourea and the alpha- and or beta-substitution compounds thereof, acylated urea or thiourea and guanidine.  The ammonia type compounds have the formula <FORM:0679758/IV (a)/2> where R1, R2 and R3 represent a hydrogen atom or an alkyl, hydroxyalkyl or hydroxyl group.  Specified are ammonia, alkylamines, hydroxylamine and alkylolamines, e.g. mono-, di-, or tri-ethanolamine.  Specified aldehydes are formaldehyde and mixtures thereof with acrolein, alpha- and beta-substituted acrolein, furfural, acetaldehyde and butyraldehyde.  The products may be used as glues, for tanning, for treating textiles and paper, for dispersions in the manufacture of artificial leather, for increasing the strength of animal and vegetable glues and for hardening movolaks.  In examples (1) urea, ammonia and water are heated, the pH adjusted to 3-4 with acetic acid and the product condensed with formaldehyde; (2) urea, triethanolamine and water are heated, the pH adjusted to 4.2 with acetic acid and the product condensed with formaldehyde; (3) thiourea, ammonia and water are heated, formaldehyde added, the pH adjusted to 3-4 and the mixture condensed; (4) urea, thiourea and aqueous methylamine solution are heated, then mixed with formaldehyde, the pH adjusted to 3-4 and the mixture condensed; (5) urea, ammonia and water are heated, the pH adjusted to 3-4, the mixture heated with acrolein, formaldehyde added, and the mixture further heated.

Abstract: 1,209,197. Casting processes; moulds. INSTITUT ELEKTROSVARKI IMENI E.O. PATONA. 26 Feb., 1968 [25 Feb., 1967 (2); 20 April, 1967; 17 July, 1967], No. 9213/68. Heading B3F. [Also in Division H5] A metal ingot, acting as a consumable electrode, is remelted by an electroslag refining process in which the electrode is held stationary relative to a cooled mould during melting and in which slag is added to the molten slag pool in the mould to maintain the electrode tip immersed in the slag. A tapered mould 1 and tapered electrode 10 are connected to a power source by contacts 7, 12, feeders 8, 13 and bus-bars 9, 14. The electrode is supported by a projection 11 on two half-ring contact plates 7 which rest upon an insulating plate 6. Molten slag is poured through a funnel 3 into the mould bottom to form a slag pool and the current is switched on. Further molten slag can be added to the space between the electrode and mould intermittently. Slag addition can also be effected by filling the space with powdered slag, or with molten slag that is allowed to solidify, so that as the slag pool moves up through the mould the solid slag melts. On completion of the refining, mould halves la, 1b (not shown) are separated and the refined ingot withdrawn. A cylindrical or prismatic electrode 22 (Fig. 5) and mould 21 can be used but the electrode cross-sectional area should be at least 9/10 of that of the mould. The refined ingot is removed on a lowerable base 27.

Title: Stirling cycle heat pump
IPC: F25B9/14
Filed: 1975-03-06
Abstract: 1484799 Stirling cycle heat pumps; heat exchangers K RAETZ 6 March 1975 9370/75 Headings F4H F4K and F4S A heat pump operating on the Stirling cycle comprises a compression chamber formed by a flexible metal bellows 7<SP>1</SP> of welded construction. The expansion chamber is formed by a second bellows 7 or a displacer and the compression and expansion chambers are connected by a regenerator and hot and cold heat exchangers 11<SP>1</SP>, 11. In the form of Fig. 1 the expansion and compression bellows 7, 7<SP>1</SP> are operated at 90 degrees phase displacement by cranks 6 on a drive shaft mounted in bearings 5. Connecting rods 8 from 90 degrees displaced cranks cause cross-beams 28, 28<SP>1</SP> to reciprocate on guides 4. The lower bellows is the hot end, compressed, heated gas being passed upwards through regenerator 9 and heat exchangers 11<SP>1</SP>, 11, which take off heat and cold respectively. To reduce the dead space in the bellows each has a metal displacer 29, 29<SP>1</SP> covered with plastic to protect the bellows. The cold end bellows 7 is surrounded by a telescopic housing carrying a regenerator 17 so that air expelled from between the folds of the bellows during compression gives up heat to the regenerator, the heat being taken up again by re-entering air during expansion. Gas passing from one bellows to the other passes through hot heat exchanger 11<SP>1</SP>, the regenerator 9, which is divided into two parts one on each side of the drive shaft, and cold heat exchanger 11. The whole apparatus may be enclosed in a pressure vessel, the pressure serving to balance the pressure in the bellows and allowing a greater amount of working gas to be used, thereby obtaining a greater output. In the form of Fig. 2 the expansion bellows is replaced by a displacer 23 operated from a second crank or a earn by a driving rod passing through the bellows 21 and sealed at 18. The gas passing between the bellows and the space over the displacer passes through heat exchanger 24, regenerator 22 and a second heat exchanger 24. The heat exchangers may be of the cross-flow type, Fig. 4, water channels 27 being formed through each of a series of elements 12, the working gas passing to and fro through channels 26 formed by spacers 13 between elements. An annular form of this heat exchanger is described (Fig. 5, not shown) suitable for the heat pump of Fig. 2. The gas passes through radial passages and the water through circular passages. The regenerators (Fig. 3, not shown) consist of a roll of corrugated metal foil interleaved with smooth metal foil to form interstices through which the gas passes.

Abstract: 250,938. British Thomson-Houston Co., Ltd., (Assignees of Nickle, C. A.). April 18, 1925, [Convention date]. Transmission-line arrangements; systems depending on two or more machines.-The maximum power transmissible by an extra high voltage line is increased by a series distributed capacitance which neutralizes the obstructive inductive reactance. The ratio of reactance to resistance may thus be made approximately #3:1 and the voltage of the receiving and transmitting ends of the line are maintained equal by automatically regulated synchronous condensers to provide stable transmission conditions at all loads. Fig. 1 shows diagrammatically a single phase transmission line with conductors 1, 2 extending from the generating end 7 and parallel conductors 4, 5 extending from the receiving end 9 for the required distance and with the required spacing from the former conductors. Synchronous condensers 11, automatically regulated by Tirrill regulators 15 to maintain the generated volts, may be arranged at the ends of each set of conductors and also across the load, for example, as indicated in Fig. 2. In a modification, Fig. 3, a condenser 11 operating upon the load circuit 10 is regulated according to the volts at the points b, b of the conductors 1, 2 and the volts at the points a, a of the conductors 4, 5 are maintained by impedances 22, 23.
