Filed: 1933-10-26
Abstract: 410,408. Supplying bobbins to winding- machines. ROSENKRANZ, C., PLUTTE, H., and HALSTENBACH, W., (trading as HALSTENBACH & CO.), 50, Nordstrasse, Barmen, Germany. Oct. 26, 1933, No. 29667. [Class 120 (iii).] A tube supplying device for cop winding machines comprises a frame slidable on guides beneath the spindles, and beneath a tube container, having bars with tube receiving notches or clips, movable vertically after the full cops have been released and dropped into a receptacle. The tubes a in the container b pass down guides c, through the slotted plate d into the notches e<1> in the frame e. The frame, which is slotted at m, is slidably mounted on guides, and is displaced horizontally by means of pins m<1> mounted in a rack f <1>. The tubes are thus carried beneath the winding heads from which the full cops a<1> have previously been dropped by retracting spring-loaded stub spindles. The bars e associated with the frame f then engage stops l, and further movement of the rack f and pins m<1> causes the bars e to rise so that the empty tubes are co-axial with the winding spindles, whereupon the spring-loaded stub spindles are released, and the tubes gripped. The frame f may be actuated by a worm and nut or by levers, and the notches e<1> may be replaced by spring clamps or grippers.

Title: Improvements in or relating to hydraulic pumps or motors
Inventor: CREIGHTON JOHN PURCELL
IPC: F01B3/00
Filed: 1956-09-28
Abstract: 852,329. Reciprocating pumps. FORD MOTOR CO. Ltd. Sept. 5, 1957 [Sept. 28, 1956; March 6, 1957], Nos. 29722/56 and 7436/57. Class 102(1). [Also in Group XXIX] A radial or axial cylinder hydraulic pump or motor is provided with a rotary distributing valve mechanism comprising an axially floating member 7 urged by liquid pressure against a valve plate 4, the forces on the floating member being balanced against tilting. As shown in Fig. 4 the floating member 7 has an eccentric cylindrical projection 7a and is housed in a suitably shaped recess in a shaft 2 so that two faces are provided at the back of the floating member, one being connected by a bore 7b to high pressure porting 7c and the other face being connected by a bore 7d to low pressure porting 7e. Ports 7c, 7e are connected to a central inlet port 4a and an annular outlet port 4b respectively. Reversing the pressure and exhaust connections will not effect balancing of the valve. A compression spring 9 provides additional loading to maintain the valve faces in contact at high and very low pressures. In the modification of Fig. 1 supply and exhaust of liquid takes place through the motor shaft which has a tube 2 inserted in a bore so as to provide an annular passage 1a leading to a rear face 3d of the floating valve member, and the tube 2 provides a passage to the other face 3c. Passages 3a, 3b lead from the rear faces to arcuate ports in the front face of the floating member which co-operate with passages in the valve plate 12 which lead to the cylinders. The motor may have rotary cylinders and a stationary shaft or vice versa. Specification 793,363 is referred to.

Title: Improvements in or relating to gas regulating and flow indicating devices
Inventor: ALDRED LESLIE
IPC: G05D7/01
Filed: 1950-12-05
Abstract: 696,592. Fluid-flow meters. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 5, 1950, No. 29726/50. Class 97 (ii). [Also in Group XXIX] A gas regulating and flow-indicating device comprises a body with an inlet 9, Fig. 1, communicating, via clearance round the stem of a closure member 6, with a chamber 2 and thence through a restriction 10 with a line 11 leading to a bubble indicator which comprises D-shaped compartments 13, 15 and liquid 16 through which the gas bubbles to the outlet 17. The pressures on opposite sides of the restriction act on opposite sides of a diaphragm 1 which controls the closure member to maintain a constant flow in the outlet. The liquid 16 is forced by the gas into compartment 15, as shown in Fig. 2, but should'reverse flow occur, e.g. due to a surge of pressure in the outlet, the liquid is blown into compartment 13 and the gas bubbles through in the reverse direction. A lip 18 prevents liquid entering the line 11. The diaphragm may be replaced by bellows and, in a modification, the diaphragm loading spring 4 is adjustable to vary the flow rate by a lever actuated, e.g. by an element responsive to pressure, temperature or time.

Title: Improvements in or relating to wireless systems or apparatus
IPC: G01S1/02
Filed: 1936-11-03
Abstract: 576,357. Directive wireless systems. HECHT, N. F. S. Nov. 3, 1936, No. 29904. [Class 40 (v)] A direction finder, free from errors due to horizontally polarised waves, comprises a plurality of spaced omnidirectional loop aerials, each aerial, the two loops of which are adjusted to phase quadrature, being associated through isolating devices with a single goniometer or cathode-ray tube. The four omnidirectional aerials A, B, C and D each comprises a pair of crossed vertical loops. Parallel loops such as 1 and 2, and 5 and 6 in the diagonally opposite aerials, are connected in phase opposition to quadrature units 9, 10, 11, 12 which, tune the loops of each aerial above and below resonance to produce the quadrature phase displacement between their outputs. Unit 11 is connected to one field coil 13 of a goniometer, wherein the outputs of loops 1 and 2 are mixed with the outputs from loops 5 and 6 due to the connection of unit 9 to the same coil. Units 10 and 12 associated with the other pair of aerials C and D are similarly connected to the field coil 14. The quadrature units 9, 10, 11, 12 contain isolating devices such as valves to prevent interaction between their inputs and the mixed outputs to the goniometer coils. The quadrature phasing may alternatively be produced by adjustment of the feeders from the aerial loops and need only be approximate, but the quadrature condition is preferable. When the phasing is so adjusted that parallel loops are of like phase, the system operates as a direction finder with zero output for both horizontal and vertical pick-ups occurring at the same goniometer setting. To determine sense, the output from an omnidirectional loop aerial, comprising a pair of crossed quadrature phased loops preferably located at the centre of the system, may be fed in series or in parallel with the output of the goniometer search coil 15. The sense aerial phase is advanced or retarded 90 degrees with respect to the outputs of the aerials A, B, C, D by means of a phasing' resistance or more conveniently by arranging that the phase of each sense loop is in quadrature with the phase of the parallel loops in aerials A, B, C, D. The central omnidirectional loop aerial may be used as a line-up transmitter if the diagonally opposite aerials are connected in summation instead of opposition by suitable switching.

Abstract: 1471610 Air cooling apparatus; air conditioning CARL MUNTERS AB 5 July 1974 [18 July 1973] 29908/74 Headings F4S and F4V In air cooling apparatus wherein air to be cooled and cooling air are respectively passed through first and second groups of channels or passageways 12 and 20 separated by parallel walls 16 through which heat exchange takes place, the cooling air passageways 20 are provided with a coating or layer 22 of porous, absorbent material, e.g. porous paper, cellulose, asbestos or glass fibres, wetted by water supplied intermittently from a spray means 34. As shown the cooling air flows downwardly through the passageways 20 in cross-flow relationship to air to be cooled passing through the passageways 12. The walls 16, which are made of fluid impermeable material such as plastics, copper or aluminium, are kept spaced apart by transversely extending walls 18 of similar material; transverse walls 24 subdivide the passageways 20 into a number of vertically extending flow channels. The cooling air supplied to the passageways 20 may wholly comprise a portion of the incoming air to be cooled (Fig. 1), a portion of the cooled air leaving the channels 12 (see Fig. 2), or a combination of both, as shown in Fig. 3, the passageways 20 in this case being divided into two separate sections. In a modified embodiment (Figs. 5, 5A, not shown) the air to be cooled and the cooling air are arranged to flow countercurrently. In another embodiment (Fig. 4, not shown), an auxiliary heat exchanger arrangement (64) provides a stream of cooling air at a desired temperature and moisture content, said cooling air stream thereafter being supplied to the main heat exchanger (10) to cool incoming air. Air supplied to the heat exchanger (64) by a fan (66) may have its moisture content reduced by first passing it through a rotary regenerative moisture exchanger (76) prior to entering the auxiliary heat exchanger (64).

Abstract: 837,503. Fluid-pressure servomotor control systems. SULZER FRERES S.A. Sept. 24, 1957 [Oct. 6, 1956], No. 29977/57. Class 135. A rotary, boiler feed-water pump 2 is permitted to return water to the feed-water tank 1 through a pipe 4 when the rate of flow through a delivery pipe 3 falls below a predetermined amount. A casing 3a contains a flow-responsive valve 13 connected to an armature 15 which is movable in a diamagnetic housing 6 outside of which is mounted, on one arm of a switch 19, a permanent magnet or an electromagnet 16. The arrangement is such that when the flow past the valve 13 is above a certain minimum value the armature 15 is situated such that the magnet 16 is drawn to the right against a spring 18 to open the switch 19, but when the flow falls below that value the spring 18 overcomes the magnetic attraction to close the switch whereby a pump 11 is energized to open a valve 5 in the pipe 4. Subsequent increase of flow past the valve 13 will cause the switch 19 to be opened resulting in closure of the valve 5. In a modification a hinged flow responsive valve 13 is employed. It is stated that instead of electrical transmission and amplification between the flow-operated switch and the valve 5 pneumatic or hydraulic transmission may be employed.

Abstract: 718,978. Regulating flow of fluids. SERVEL, Inc. Dec. 28, 1951 [Jan. 16, 1951], No. 30287/51. Class 135. [Also in Groups XII and XIII] A heat transfer conduit t of a refrigerating system is inclined to the horizontal and has capillary grooves g extending along its inner wall with ascending and descending portions providing a syphon so that liquid supplied to the upper end of the conduit flows continuously along the grooves above the liquid level at the bottom of the tube. As shown, the conduit has a plurality of closely adjacent long-lead helical grooves, and liquid flowing along the bottom of the conduit by gravity is lifted by capillary action to the top of the conduit. Due to the inclination of the conduit, the head of liquid in the descending portions of the grooves is greater than the head in the ascending portions and overcomes the capillary action in the descending portions to cause a continuous flow along the grooves, wetting the entire inner surface of the conduit. The invention may be applied to the absorber or the evaporator of a continuous-cycle absorption refrigerating apparatus, weak liquor or liquid ammonia being fed to the upper ends of the tube by a peripheral capillary groove or a gauze wick 54 held in place by an annular ring 55. A helical baffle may be provided to create turbulence in the hydrogen passing through the tube. Adjacent inclined tubes may be connected by elbows 50 feeding the liquid from one tube to the next or a single length of tube may be bent to form a serpentine coil. Specification 602,805, [Group XIII], is referred to.
