Title: Improvements relating to control and switching means for traversing devices in textile, spinning, winding or ring-twisting machines
IPC: B65H54/28
Filed: 1965-02-02
Abstract: 1,096,933. Building motion. BARMER MASCHINENFABRIK A.G. Feb. 2, 1965 [March 18, 1964], No. 4516/65. Addition to 1,064,162. Headings DID and D1J. [Also in Division G1] The control and switching arrangement for mechanically or hydraulically driven traversing devices in spinning, winding and ring twisting machines claimed in claim 1 of 1,064,162 is modified in that two or more impulse generators are provided. By using more than one impulse generator different impulse rates may be produced so that the rate of changing the positions of the reversing switches may be changed for different stages of the build, e.g. during stroke reduction and during stroke increase. As shown a disc 44 preferably rotated at a constant speed has projections 50, 50<SP>1</SP> which interrupt beams of light passing from sources 42, 42<SP>1</SP> to photocells 43, 43<SP>1</SP> respectively, so that different impulse rates are emitted from the cells. A switching arrangement is provided such that impulses from only one cell at a time are amplified to control the speed of the reversing switches. The arrangement for switching from one cell to the other may be operated by switches which are operated by the movement of the reversing switches. The impulse generators 41, 41<SP>1</SP> are mounted on a slide to be radially movable of disc 44 by a rotatable wedge 54 so that the impulse rate can be adjusted. In a further form the generators may be spaced, but at the same distance from the centre of a common disc and be adjustable parallel to or tangentially of the circumference of the disc. Photo-electric and electromagnetic impulse generators may be used together.

Abstract: 815,913. Toothed gearing; friction gearing; variable-speed gearing. FICHTEL & SACHS A.G. Feb. 15, 1956 [March 31, 1955], No. 4775/56. Classes 80 (1) and 80 (2). In epicyclic friction or toothed gearing an eccentric planetary annular member 3, Fig. 1, is rolled around a fixed reaction member 1 by one or more rollers 5 on a driving carrier 6 formed with an input gear 11, the output gear 12 being connected to the gyrating member 3 by a coupling 8, or by an articulated shaft or a resilient coupling. The interengaging surfaces of the members 1, 3 may be smooth, ribbed or toothed, and the gearing may be arranged so that the gear 12 drives the gear 11. The rollers 5 may be replaced by slide blocks. The member 3 may be elliptical to give a non-uniform angular velocity. In a modification the rollers 5 act on the interior of the member 3. In a further modification a number of rollers 5 are held in a cage and are arranged around the member 3 to form an external bearing therefor. The running surfaces of the members 1, 3 and 5 may be cylindrical or of concave or convex section. In order to provide a change-speed gear one or both of the members 1, 3 may have a plurality of steps. In Fig. 6 the annular member 3 is stepped and frictionally engages a stepped reaction member 1 which, together with the carrier 6, is movable axially of the member 3 by means of a spring-loaded rod 16 and thrust elements 17. The outer surface of the member 3 may be cylindrical, conical or spherical. In a modification, Fig. 7 (not shown), the member 3 has a peripheral groove engageable by an eccentric disc on a shift spindle so that on rotation of the spindle the member 3 is radially disengaged from the member 1 whereafter the member 3 may be axially displaced relatively to the member 1 to vary the speed ratio by axial movement of the shift spindle. In a further modification the members 1 and 3 have conical or arcuate frictionally-engaging surfaces to provide continuously-variable change-speed gearing. Such gearing may be arranged so that in one limit of adjustment the output gear is stationary and the gearing may then be employed as a clutchless vehicle transmission. The gearing may be rendered automatic by the use of a regulator operating in dependence upon speed or torque.

Title: A fuel-rod assembly for liquid-cooled nuclear reactors
IPC: G21C3/32
Filed: 1963-02-06
Abstract: 1,026,845. Reactors. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Feb. 6, 1963 [Feb. 6, 1962; Jan. 30, 1963], No. 4822/63. Heading G6C. A fuel element (Figs. 1a, 1b, not shown) comprising fuel rods 6 disposed within an annular channel 5 between coaxial tubes 4, 7 has a number of baffles 12 disposed helically round its longitudinal axis and provided with bores to receive the rods 6 so that coolant flowing through the channel 5 has a transverse as well as a longitudinal component of flow. This overcomes the disadvantage with pure longitudinal flow that the coolant has a higher temperature adjacent the fuel rods which lie towards the centre of the core than adjacent those situated towards the edge of the core. In a light watercooled and moderated reactor employing fuel elements of this construction (Fig. 2, not shown) the water enters through a valve 28 at about 300‹ C. and is divided equally between an upper distributer ring 20 and a lower distributer system 16. From the latter, the water flows up supply tubes 11 housed within inner moderator compartments 10 of the fuel elements to be deflected by the closed ends of inner casing tubes 9 down through the compartments 10 whence it rises outside outer casing tubes 2 through an outer moderator compartment 1 to flow laterally through a gap formed between a fuel element support grid 17 and a dividing plate 18 into a compartment 19 where it mixes with the water from the distributer ring 20. The water subsequently flows up through the channels 5 where it is preheated to critical temperature and then superheated to 600‹ C. The superheated steam is collected in an insulated dome 21 above the grid 17 and supplied to a turbine through an insulated conduit 24. The necessary pressure drop for the flow through the channels 5 is produced by a cushion of pressure gas 27 above the free surface 26 of the water, the pressure of which is regulated by a valve 33 and regulator 37 connected by a conduit 32 to a gas container 31, excess gas being released through a valve 38. The temperature of the superheated steam, measured by means of a temperature detector 30, is used to adjust the setting of control rods 29. Since, however, this adjustmen involves a few seconds delay, the control rods must be preliminarily adjusted directly by the turbine, the generator or the mains on variations in load and the temperature used only for fine adjustment. The water level in the reactor pressure vessel 14 is maintained constant by means of an automatic regulator 39. Emergency shut-down of the reactor is effected by forcing gas from the container 31 through a valve 35 in a conduit 34 into the distributer system 16 to displace the water from the moderator compartments 10 and the supply tubes 11, thus rendering the reactor sub-critical.

A purified silica gel is impregnated with the palladous sulphate solution, sulphuric acid, and ammonium molybdate to obtain a gas indicator containing gel 500 to 1600 parts; acid 5 to 50 parts (containing 1 part of palladium); and molybdate 10 to 60 parts.  The gel is purified by boiling with concentrated nitric acid and then thoroughly washed.  A gas detector comprises a tube 11 containing the indicator gel 10 housed between guard gels 12 and 13, and water-indicating gels 18, some of these latter may be housed in a separate tube which can be replaced when exhausted.  Comparator gels 20, which do not contain any palladous sulphate, are placed on each side of the indicator gel.  The indicator is applied to the detection of carbon monoxide but may be modified for other gases, e.g. gasoline, ether, ethylene, the halogens, ozone or oxides of nitrogen gases which reduce the yellow silicomolybdate complex or oxidize the green or blue complexes, as the colour change is reversible.  The carbon monoxide saturation of the blood may also be determined.
