Abstract: 981,083. Refrigerating. SIEMENS-ELECTROGERATE A.G. April 13, 1961 [April 13, 1960], No. 13383/61. Heading F4H. [Also in Division H1] In a heat pump having thermoelectric elements mounted in a planar array in such manner as to present the junctions of one type at one face and of the other type at the other face and in which one face is in heat-exchange relation with a heat transfer system using an evaporating-condensing heat-transfer medium, the transfer system is so mounted or constructed that it can serve to supply heat to or convey heat from the heat pump depending on the direction of current supply to the thermoelectric elements. As shown in Fig. 1, the array of elements 21 is vertical in use, the face 27 absorbs heat and heat is conveyed from the opposite face by liquid evaporated in chamber 22, the vapour being condensed in finned heat-exchange member 24, 25 and returning to the evaporator. The parts of the heat transfer system are so disposed that, when the whole apparatus is inverted to the position shown in Fig. 3, the system will convey heat to the elements, liquid being evaporated in member 24, 25 and condensed in chamber 22, the current supply being reversed. The elements are embedded in foam insulation 28. As shown in Fig. 4, the transfer system conveys heat from the elements 31 and is attached thereto by clamps 39, the upper face 32 being cold. By mounting the system in inverted position in the clamps and reversing the current, the system conducts heat to the elements, the face 32 being hot. As shown in Fig. 6, the system is fixed to the elements but includes a flexible portion 42. When the part 43 is moved to the dotted position from the full-line position and the current is reversed, the top face 32 is heated instead of cooled. The secondary medium is a fluorinated aliphatic hydrocarbon. The other face of the elements may be finned or in heat-exchange with a medium, preferably one which changes from the solid to the liquid state and vice versa on change of temperature.

Abstract: 135,591. Goold, L. W., (American Laundry Machinery Co.). Nov. 27, 1918. Starch.-Starch mixture for use in laundries &c., and which may consist partly of cooked starch and partly of uncooked starch, is creamed by withdrawing the mixture from the vessel in which the ingredients have been cooked, and returning it again to the vessel, for example, in the form of fine jets; and in order to adjust the temperature of the mixture and maintain it at the proper degree of viscosity while obviating any partial cooking of the uncooked starch, the starch mixture may in its external circuit be passed through a temperature-controller which serves to cool or to supply heat to the mixture. A suitable apparatus is described in Specification 135,588. In this, the starch is first cooked with water in a vessel 1 by steam or other heating medium introduced through a series of inclined nozzles 19, Fig. 8, surrounded by open-ended sleeves 20; and the discharge of the steam &c. produces an injection action at the nozzles, causing intimate admixture of the materials to be cooked and at the same time producing a thorough circulation by the upward swirling movement. If the starch mixture is to be used at a relatively high temperature as in the starching of yarn and warp threads, it is now creamed; thus, the mixture is withdrawn by a pump 10 from the lower part of the vessel 1, and returned to the upper part through a finely perforated nozzle 48 which may be set at an angle so as to produce a circulation of the liquid in the vessel. If, however, a mixture containing both cooked and uncooked starch is required, as in the starching of collars, &c., the cooked mixture in the vessel 1 is allowed to cool, for example, by standing or by circulating cold water through pipes passing through the vessel or by circulating the mixture by means of the pump 10 through a temperature-controller supplied in this case with cold water; when the mixture has been cooled to the proper temperature, the remainder of the uncooked starch is added, and the mixture is then creamed as before. To strain the mixture, it may be passed through a cloth or fabric bag fitted in place of the creaming nozzle: or it may be passed through a series of filtering screens fitted in a branch separate from the creaming nozzle.

A calendar timepiece has hour and minute hands which may be set manually by a rotatable stem assembly adapted in an "out" position to engage a setting mechanism, and which are disengaged from the setting mechanism in an "in" position of the stem assembly, means inter-coupling a finger and the stem assembly only at the "in" position thereof whereby rotation of the stem assembly causes the finger to turn a date ring, and an automatic trigger mechanism to advance the date ring once per day. When the stem 11 is withdrawn to its "out" position a clutch wheel 13 thereon is engaged with a setting wheel (not shown) inter-meshing with the minute wheel to permit setting of the hands by rotation of the stem 11. In the "in" position of the stem 11 teeth 18b on the clutch wheel 13 engage ratchet teeth 18a on a collar 18 on the stem 11. Rotation of the stem 11 then advances a date ring 16 by the engagement of a tooth 19 on the collar 18 with teeth 17 on the date ring 16. The trigger mechanism for the daily advance of the date ring 16 comprises a finger 24 rotated by the hour wheel 15 continuously at one rotation per day within an opening 25 in a trip arm 26. An end 31 of the latter is slidable in a slot 27 in a pillar plate PP to permit the arm 26 to move against the action of a spring 30 when the finger 24 engages a notch (not shown) in the edge of the opening 25. At midnight the finger 24 disengages from the notch and the spring 30 impels the trip arm 26 against a bumper 29, a nose 28 on the moving trip arm 26 then engaging a tooth 17 to advance the date ring 16. Simultaneously with the advance of the date ring 16 a day ring 41 is advanced by the engagement between teeth 42 thereof of a pin 43 projecting from the trip arm 26. In two alternative embodiments the end of the trip arm 26 is not slidable in a slot in the pillar plate, but in one construction is provided with a slot within which is received a guide pin secured to the pillar plate, and in the other is formed as a tongue slidable between two cam members secured to the pillar plate.

Title: Improvements in or relating to electric generators
IPC: H02K23/20
Filed: 1937-05-18
Abstract: 495,779. Exciting dynamos. HOLMES & CO., Ltd., J. H., and BAYLES, J. W. May 18, 1937, No. 13894. [Class 35] The invention relates to electric generators for purposes, such as welding, requiring a falling characteristic and is concerned with generators of the type having main poles B, C and auxiliary poles D, E arranged so that the flux in the former tends to be increased by armature reaction but is restricted by saturation, whilst the flux in the latter tends to be decreased and reversed by armature reaction ; an auxiliary brush F<3> is provided in addition to the main brushes F<1>, F<2> and the voltage between certain brushes varies comparatively little while that between other brushes is reduced or reversed. According to the invention the generator has on at least one auxiliary pole, for example the pole E, a shunt winding E<1> connected between brushes F1, F2 between which the voltage is reduced or reversed with increase of armature current and on at least one auxiliary pole a series winding D<2> or E<2> tending to increase the flux or to oppose its reversal with increase of armature current. The windings B<1>, C<1> on the main poles and the winding D<1> on the auxiliary pole D are connected across the constant voltage brushes F2, F3. In a modification, the winding D<1> is connected across the brushes F<1>, F<3> and the winding E' across the main brushes. The windings D<1>, E<1> may be connected in series or in parallel across the main brushes. Two or more auxiliary windings may be connected across brushes between which the voltage reverses with increase of armature current, but it is desirable to maintain stability by providing a winding through which the current is never reversed. More than one auxiliary brush may be provided, an auxiliary winding being connected across two such brushes or each auxiliary winding across a main brush and an auxiliary brush. Other arrangements described are: (1) windings B<1> and D<1> in series between brushes F2, F<3> and windings C<1> and E<1> in series between brushes F<1>, F3, additional compounding series windings being provided on the main poles ; (2) windings B<1> and D<1> in series across the main brushes and windings C and E<1> in series across brushes F', F<3> or F<2>, F3. A winding may be divided between different poles. The auxiliary poles are of greater section than the main poles and are saturated on open circuit but are unsaturated at short-circuit. Resistances which may be varied differentially or together may be connected in series with the auxiliary pole shunt windings. Control of the current may also be obtained by the provision of tappings on the auxiliary pole series windings and by brush rocking.
