Title: Improvements in freezing apparatus for use in the concentration of fruit juices
IPC: F28D1/06
Filed: 1926-07-13
Abstract: 278,799. Heyman, W. A. July 13, 1926. Solidifying liquids other than water. - Fruit juices are concentrated by freezing out the contained water in apparatus comprising an inclined cylindrical chamber 1 surrounded by a jacket for a cooling-medium such as brine or ammonia, the juices being admitted to the chamber through a pipe 19 at the lower end and the cooling-medium being passed into the jacket at the upper end. The jacket is preferably provided with helical baffles 2 and fins 26, Fig. 2, the baffles being either formed integrally with or attached to the chamber wall. The chamber is fitted with a worm conveyer 16 having perforations 18 and peripheral notches increasing in number from the lower to the upper end, whereby ice is detached from the walls and fed with the liquid towards an outlet 8 at the upper end. The chamber and jacket may be, drained through valved pipes 24, 22, and if desired a gas such as carbon dioxide may be admitted through the lower end to displace air and thereby avoid risk of contamination. The ice may subsequently be separated from the liquid in centrifugal devices. The freezing process may be regulated by adjusting the flow of cooling-medium, the supply of juices and the speed of the worm 16. Reference has been directed by the Comptroller to Specifications 9672/84, 24870/04, and 27823/11.

Abstract: 145,667. Hoover Suction Sweeper Co., (Assignees of Hoover, H. E.). July 14, 1916, [Convention date]. Capillary-action lubricating.-A hollow vertical shaft of a suction-cleaner motor &c. has means for preventing excess lubricant from being seattered upon the. surrounding mechanism or from running to waste both while the shaft is rotating and at rest. Lubricant is supplied through an aperture G in an end-yoke A<2> to the hollow shaft B<1>, which contains a wick J<3> to retard the flow, an armature B being mounted on the shaft. A permeable disk G<2>, secured between an upper bearing-sleeve D and the yoke A<2>, acts as a distributor for the lubricant, part of which passes through the shaft and an opening M to a lower bearing-sleeve E, whence it passes into a dust chamber C, from which it is carried away with the dust-laden air by a fan C<3> secured to the shaft. A part of the lubricant passes along the upper bearing-surface into a cup J, secured to the shaft and adapted to retain the lubricant when rotating. When rotation is stopped, this oil passes along channels J<2> to the interior of the shaft. The sleeve D rests on a flange B<2> of the shaft, with intermediate packing, but, in a modification, the cup J may rest on the flange, and the sleeve D and packing rest on the cup, grooves being provided in the base of the cup to communicate with the channels J<2>.

Abstract: 237,279. Loffler, S. July 18, 1924, [Convention date]. Indicators actuated by floats.-A liquid level indicator applicable to high pressure steam boilers comprises a float connected by flexible means to a counterweight which is adapted to vary the inductance of an electric circuit and thus indicate the Level. A vessel 1 connected to the boiler contains a float 3 connected by a wire 5 to an iron counterweight 6 suspended in a fluid which is kept cool by a jacket 8. The weight 6 moves within two coils 9, 10 connected to an alternating current generator 11 through two crossed coils 18, 19 in the field of an electromagnet 20 which is energized by the generator 11. The movement of the weight 6 varies the relative inductance of the coils 9, 10, which causes an angular movement of the coils 18, 19. The movement is transmitted to a pointer 22. The float 3 may contain some water, so that the internal pressure approximately follows the external. Specification 224,881 is referred to.

Title: Automatic paralleling circuits for ac generators

Filed: 1971-06-01
Abstract: 1326689 Automatic paralleling of A.C. generators GENERAL ELECTRIC CO 1 June 1971 [24 June 1970] 18356/71 Heading H2H A circuit for connecting selected A.C. generator 10 or 12 to main lines L1, L2 carrying A.C. comprises a contactor winding 24 or 26 for coupling the selected generator to the main lines and a switch such as a thyristor 22 for energizing contactor winding, the switch being controlled by contacts a<SP>1</SP>, c<SP>1</SP>. To connect the first generator, for example the generator 10, to the main lines a ganged switch S1-S4 is set to its position S10 so that manual operation of a switch 32 causes the thyristor 22 to conduct and the winding 24 of the contactor 14 to be energized by the output of rectifiers 28. The contactor 14 and holding contacts 14<SP>1</SP> are therefore closed, a relay D also being energized to open contacts d thereby switching off the thyristor. In order to connect the generator 12 to the main lines, the ganged switch S1-S4 is changed to its position S12 and a master switch 44 is closed. Relays A and B having associated contacts a<SP>1</SP>, a and b are supplied by a source 18 the output of which is equal to the difference between the voltage on the line L1 and the voltage on the line l1. A third relay C having associated contacts c, c<SP>1</SP> is supplied from a source 20 connected to the line L1. As the output of the source 18 increases the relay A operates to open contacts a<SP>1</SP> and close contacts a thereby enabling the relay B to close the contacts b when the output nears its maximum. The relay C is therefore energized to close the contacts c, c<SP>1</SP> but as the voltage of the source 18 starts to fall the relay B operates to open the contacts b. As the output of the source 18 approaches zero the relay A is deenergized thus closing the contacts a<SP>1</SP> and since at this instant the contacts c<SP>1</SP> are also closed, the thyristor 22 is fired to operate the contactor 16 and connect the generator 12 to the main lines. The thyristor may be replaced by a relay actuated by the contacts a<SP>1</SP>, c<SP>1</SP> or the contacts a<SP>1</SP>, c<SP>1</SP> may replace the thyristor provided the relays A, C are larger. Alternatively an A.C. relay and a triac may be used in place of the thyristor. A modification is also described for connecting three phase generators to three phase main lines.
