Title: Improvements in or relating to internal combustion turbine power plants
IPC: F01D5/18
Filed: 1944-01-31
Abstract: 592,448. Cooling turbine &c. blades. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and HAWTHORNE, W. R. Jan. 31, 1944, No. 2396/45. Divided out of 592,615, [Group XXVI]. [Class 64 (ii)] [Also in Group XXVI] The blades of two-tier rotor, in which the inner ring of blades 12 are the blades of an air compressor, and the outer ring 13 those of the turbine, in a gas turbine plant, are made with a sealed hollow 15 containing some sodium 17 or suitably fusible salt. When the turbine is operating, the sodium fuses and is driven to the outer end of the blade which is heated by the turbine gases. The sodium that evaporates there condenses in the inner, colder portion of the hollow and thereby transfers heat from the turbine blade to the compressor blade.

Title: Improvements in or relating to apparatus for preparing tins for use in cooking
IPC: A21B3/16
Filed: 1928-01-25
Abstract: 312,378. Lyons & Co., Ltd., J., and Herbert, S. G. Jan. 25, 1928. Baking-trays and the like, greasing and powdering.-A machine for preparing tins for use in cooking comprises a conveyer which conveys tins in succession past a grease sprayer to a sugar sprayer and from thence to a flour sprayer. As shown, an endless steel band 2 receives the tins from a cross conveyer 5 which may be associated with the apparatus described in Specification 312,377. The grease sprayer 6 comprises a number of downwardly-directed nozzles 8 the major portions of which are surrounded by a hot-water bath 9. Surplus grease, in a fine state of suspension in the air, which would otherwise spread to the surrounding atmosphere, is withdrawn through a duct 10 leading to a fat separator, e.g. such as that described in Specification 311,204, [Class 123 (iii), Steam separators &c.). The sugar distributer comprises a hopper 12 containing a rotary paddle 13 delivering the sugar to a roller or other distributing device which sprinkles the greased tins with sugar. The flour sprayer comprises a hopper 15 containing a rotary paddle 16, Fig. 4, delivering the flour to a blanketcovered roller 17 from which it is brushed on to the tins by a rotary brush 19. An adjustable slide 18 determines the amount of flour deposited. The tins pass to a region S where they are caused to overturn and fall in an inverted position on a grid 20, thus shaking off any surplus material which is collected at 21. The machine is driven from the electric motor 22.

Abstract: 1422492 Boarding and inspecting hosiery S LEONHARDT 18 Jan 1974 [20 Jan 1973] 02486/74 Heading D1S A boarding or examining form 1 for stockings or pantihose is provided with endless belt drives 3 along both longitudinal sides of the form, the belts being guided by pulleys 4 within the form contour.  As shown in Figs. 1 and 2, a transparent plastics stocking form is provided with two circular-section endless rubber belts 3 of each of which only one run 5 protrudes out of the form and which are driven by a motor (not shown). When the top opening of a stocking is offered to the board from below, the belts 3 running in the direction of arrows 7 grip and draw the stocking onto the form. The belt drive is switched off, e.g. by the automatic control of a photo-electric cell. The stocking may be inspected by a light source arranged within the form or may be heat treated either by an internal heating device or by introducing the form into a heating chamber. After treatment, the stocking is removed from the form by movement of the belts 3 in the direction opposite to the arrows 7. Additional guide rollers 3a may be arranged at the free end of the form. An ejector plate, 6b, mounted on a ram 6a driven by a piston drive 6c, strikes the foot end of the stocking to ensure satisfactory removal. An attachment 8, Fig. 3, having belt drives 9 may be pivotally mounted on the form and is movable from the full line position to a position 8a to stretch the foot section of the stocking. A form for pantihose, Figs. 4 and 6, comprises two adjacent forms with an additional belt drive 11 arranged therebetween to grip and fold over the pantie section 12 during withdrawal of the pantihose. The drive 11 is pivotally mounted so that during loading of the hose it remains outside the region of the forms. The forms may be disposed obliquely to one another so that they lie closer together at their free ends than at their fixed ends.

Abstract: 898,574. 1,2,4-Trithiolanes. LEUNA-WERKE WALTER ULBRICHT VEB. Jan 23, 1959 [April 8, 1958], No. 2575/59. Class 2 (3). Aliphatic or cycloaliphatic substituted 1,2,4- trithiolanes are prepared by reacting an aliphatic aldehyde containing 2 or more carbon atoms or an aliphatic or cycloaliphatic ketone with sulphur and hydrogen sulphide in the presence of ammonia or an amine at low temperatures, preferably in the range 0‹C-10‹C. The reaction takes place as follows when butanone is used as starting material Preferably hydrogen sulphide is introduced at 0‹C. into a mixture of 2 moles of the aldehyde or ketone and 1-2 moles of amine, and 1 gm/atom of sulphur is then added gradually. When ammonia is used it is preferred for equal volumes of ammonia and hydrogen sulphide to be first introduced into the aldehyde or ketone. The trithiolanes when treated with an amine decompose to give imines, hydrogen sulphide and sulphur. Examples are given of the preparation of (a) 3,3,5,5-tetraethyl-1,2,4-trithiolane from diethyl ketone; (b) 3,5-dimethyl-3,5-di-n-propyl- 1,2,4-trithiolane from methyl propyl ketone; (c) bis - 3, 3,5,5 - pentamethylene - 1,2,4 - trithiolane from cyclo-hexanone; (d) 3,3,5,5-tetramethyl- 1,2,4-trithiolane from acetone; and (e) 3,5-di-npropyl-1,2,4-trithiolane from butyraldehyde. In the preparation of 3,3,5,5-tetramethyl-1,2,4-trithiolane some duplo-di-thio-acetone of formula is also formed.

Abstract: 159,745. Martin, W. E. Jan. 28, 1920. Cultivators; ploughs.-In a cultivator or plough in which the main wheels a are carried on a cranked axle f and the tools c are lifted from the ground by rocking this axle, using power obtained from a toothed wheel on one of the main wheels, means are provided to permit the tools to rise without affecting the main wheels when an obstruction is encountered. A cranked frame g is mounted on the stub axles at the ends of the crank-shaft f and extends upwards in a plane inclined to that in which the cranked axle f lies, the axle f and the frame g being connected by stays h. A crank-shaft i is mounted in the upper part of the triangular frame thus formed, and is connected by an adjustable link through a slot-and-pin connection m<2> with a height-adjusting hand-lever m. A sprocket-wheel driven through a chain from a sprocket-wheel on one of the main wheels a is loosely mounted on the shaft i, but is adapted to be clutched to it by freeing a roller from a clutch member e. On operation of this clutch member, the shaft i rotates through half a revolution rocking the triangular frame f, g, h about the axle f through its pull on the link to the height-adjusting lever. A second operation of the clutch member retrieves the shaft i to its original position with the tools in operative position. Should the tools strike an obstacle, the frame lifts, the slot connection to the lever m permitting this movement without the wheels a being affected.

Abstract: 136,369. Robinson & Co., A., Gill, J. F., and Chaviara, J. N. Feb. 5, 1919. Addition to 123,830. Order-type apparatus.-In the electric synchronous movement system described in the parent Specitication, one of the electro-magnets operating the oscillating contact-arm is replaced by a resistance, and the contact-arm is moved in one direction by a spring. In the arrangement shown in Fig. 1, an operating-magnet o and a resistance d at the transmitting-station are connected in series across the battery 5, and the operating-magnet c<1> and the resistance d<1> are similarly connected at the receiving-station. The oscillating contact-arms a, a<1> are also controlled by springs s. In the condition shown, the magnet c is energized, and the magnet c<1> de-energized, so that the arm a<1> moves to engage, the contact g<1> under the action of its spring s, thereby deenergizing the magnet c. The arm a is moved to engage contact g under the action of its spring s, thereby energizing the magnet c<1> and causing the arm a<1> to engage contact f<1> to energize the magnet, which moves the contact-arm a into engagement with contact f when the above-described operation is repeated. To obtain reversal of rotation of the operated mechanism, the transmitting and receiving stations are each provided with a pair of operating-magnets c, c<1>, Fig. 2, and their selective energization is obtained by a switch 6.
