Title: Thermoelectric Cascade
Inventor: POSLT ZDENEK
IPC: H01L35/32
Filed: 1967-07-13
Abstract: 1,151,947. Thermo-electric cascades. TESLA NARODNI PODNIK. 13 July, 1967 [2 Aug., 1966], No. 32326/67. Heading H1K. A thermo-electric Peltier effect cascade consists of a hot stage H separated by an electrically insulating but thermally conducting layer I from a cold stage C. The two stages are electrically interconnected in series or series-parallel and the relative dimensions and/or manner of interconnection of the thermo-electric elements in the two stages is such that, when both stages are energized from a common voltage source, the current in the cold stage is of a lower "relative intensity" than that in the hot stage. "Relative intensity" is defined as the ratio of the current actually flowing in a stage to the current which would produce maximum cooling effect in that stage. It is stated that conformity to this condition can produce a cascade having a higher overall temperature difference than would be the case if the same thermo-electric elements were connected in a maximum-efficiency cascade. Fig. 3 shows a series-parallel connection between the stages H and C, in which the number of thermo-electric elements is the same in both stages but in which the cold stage has a lower current. A similar arrangement, but with up to five times as many elements in the cold stage as in the hot, is also described. Fig. 2 (not shown), depicts an arrangement in which stages H and C are connected electrically in series but with the cold stage elements having a lower length to cross-sectional area ratio than the hot stage elements.

Class 87(ii) Relates to machines for manufacturing concrete pipes of the kind in which the pipes are formed in a mould resting with its bottom end upon a vibration table and composed of an inner cylindrical core and an outer substantially cylindrical form which is exposed to vibrations at its top end other than those emanating from the vibration table, and consists in a vibrator at the top end of the mould movable in guides 21 to or from the mould and in means 38-41, or 43, 44 for detachably securing the vibrator to the outer form 12 in contact with the form. The core 16 is received in an opening in the flange 10 of a conical ring 9 which rests on the vibration table 8, and the outer form 12 rests by its enlarged bottom end on a flange 11 on the ring 9 and is secured by links 13 with ends hooked round the flange 11 and a flange 15 on the form 12. The guides 21 are fixed to a frame 20 at the side of the vibration table and comprise rails for wheels on a frame 23 which carries an electric motor and a vibrator driven by belts therefrom. The vibrator comprises a sleeve 28 surrounding a shaft 29 which carries an eccentrically loaded disc 30, this disc being provided at one side with a series of threaded bores whereby the eccentric load can be adjusted by inserting threaded pins in the bores. The vibrator is carried between the shanks 27 of a U-shaped yoke bolted at 26 to the frame 23 with the inclusion of a rubber disc 33 to damp the transmission of vibrations to the frame. Two T-sectioned irons 18 are secured to the flange 15 and to a flange 17 at the top end of the form 12 From each end of the U-shaped yoke there projects a pin 35 with a tapered end to engage a conical bore in an iron 18, and there also projects a plate 36 of which the vertical edge 37 meets an iron 18. 38 are links swingably mounted on the yoke and 39, 41 are the shorter and longer arms of a two-armed lever, the arm 39 having a tapered end to engage a recess 40 in an iron 18.

The surfaces 18 are recessed between spaced guide segments or supports 40. The surfaces 18 are maintained at substantially constant refrigerating temperatures for relatively prolonged periods of time by substances which may be a starch based gel refrigerant or an endothermic entectic composition, of which examples are given. Alternatively gel refrigerants may be used based on colloidal systems of water, borax and xanthan gum which may be prefrozen prior to loading through a filler 45 into the cartridge, or liquefied gas cartridges, e.g. of nitrogen or carbon dioxide may be used with the cartridge to pre-cool the refrigerant charge. The cans and bottles also may be pre-cooled.

Title: Steam injection type water heater
IPC: F24H1/10
Filed: 1945-12-10
Abstract: 607,974. Fluid-pressure servomotor-control systems. PICK MANUFACTURING CO. Dec. 10, 1945, No. 33354. Convention date, Jan. 11. [Class 135] [Also in Group XIII] In a water heater, steam is supplied internally to a tube T with a multitude of orifices 42, a variable number of which are opened for the escape of steam into the water flowing through a casing A surrounding the tube T, by movement of a piston P within the tube against the action of resilient means, such as a spring 44, in response to changes in steam pressure. A stop 46 limits the closing movement of the piston so that some orifices are always open for the escape of steam. The orifices have a slight inclination in the direction of water flow and, in a zone near the bottom of the tube, are progressively reduced in number downwardly so that equal small upward movements of the piston at the bottom of the tube expose progressively increasing numbers of orifices. Helical vanes 62 are provided on the inside of the casing A. Steel balls 56 retained in position by grids 57, 58 break-up the flow of steam through the conduit 38 to the tube T. The pressure of water supplied to the heater through the pipe 18, Fig. 1, is kept constant by a valve 17 operated by a diaphragm unit 21 responsive to pressure changes in the pipe 18. The pressure of steam supplied to the heater from a pipe 14 is varied to keep the temperature of the heated water constant by a valve 24 operated by a diaphragm unit 26 responsive to pressure changes transmitted through a tube 30 by a thermostatic device 27 which applies pressure from a pipe 31 or relieves it through a pipe 32 in response to temperature changes in a thermal element 28 which projects into the conduit 29 leading to the hot water outlet pipe 13. To prevent formation of large steam bubbles in the heater, a pump 63 recirculates water from the conduit 29 through the heater when the rate of withdrawal of hot water through the pipe 13 is so hot that the rate of water flow through the heater would otherwise fall below a predetermined minimum.

Vaporizers, external.-Steam is generated from the cooling water which, after leaving the jacket 1, passes through a coil 6 in the exhaust pipe 7 and is then sprayed from the pipe 13 on to the crown of the combustion chamber 12 in the chamber 10. The steam is used to spray heavy fuel in a chamber 21 by entering the valve chest 15, Fig. 21, through the valve 22 and meeting as it issues over the surface of the valve 17, oil which is forced from the pipe 16 through perforations in the seating 60. The mixture of steam and oil vapour is admitted through the slide valve 23 to the cylinder during its compression stroke and is fired by a sparking-plug.
