Title: Sorting Bodies of Ferromagnetic Material
IPC: G01N27/72
Filed: 1969-01-14
Abstract: 1,194,995. Magnetic separation. STATNI VYZKUMNY USTIAV TEXTILNI. 14 Jan., 1969 [15 Jan., 1968], No. 2050/69. Heading B2J. Bodies of ferromagnetic material are sorted by reference to their respective permeabilities by means of a measuring coil 1 which is provided with a core 2 supporting two convergent pole pieces 3 between which is an airgap 4 trapezoidal in section constituting a passageway for travellers 5 for a ring spinning machine, the travellers being carried in radial notches 6 of a transport wheel 7. In their uppermost position the travellers are prevented from falling 'by a trap plate 8 operated by the armature 10 of an electromagnet 11. The measuring coil is connected to a resistance bridge 13 the output voltage of which is zero when a traveller of nominal hardness is situated in the middle zone of the air gap 4 causing the electromagnet 11 to be de-energised tilting the trap plate 8 and allowing the traveller to fall into a receptacle. Travellers of a greater or lesser hardness cause the trapplate to tilt when the traveller is at one or either end of the air gap.

Abstract: 1303973 Control of winding mechanisms ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 15 Jan 1971 [21 Jan 1970] 2082/71 Heading D1J A winding unit with a brake and clutch is controlled by the device of Fig. 1 in which a shaft 100 rotates continuously and via cam 105 and roller 106 rocks lever 107 which is firmly attached to shaft 108 and hence rocks lever 8. Lever 8 acts on the winding mechanism, Fig. 2, to disengage driving pulley 14a from clutch plate 13 but without engaging brake disc 17. This disengages drive to a shaft 15 carrying the distributor roller 16 and hence eliminates pattern winding. In the event of yarn breakage a stop motion (not shown) swings member 113 into a position to be engaged by lever 104 which swings continuously under the influence of cam 101. Lever 27 is thus rotated in a clockwise direction and via roller 122, lever 107 &c operates both the clutch 13 and brake 17 to stop winding. Additionally an edge (110), Fig. 4 (not shown) of lever 27 releases pawl (28), which rotates continuously with shaft (100), to engage a clutch (30) for one revolution. Clutch (30) is geared to shaft 111 and also drives a knotting mechanism (not shown). Cam 121 on shaft 111 controls (via lever 117 and hence lever 27) the operation of the winding unit to suit the knotting process and after a complete revolution recess 121a returns lever 27 to the normal position to restore normal winding. A manual override (32) is also provided to act on the pawl (28).

Title: Improvements in or relating to hydraulic lifting apparatus
IPC: B66F3/42
Filed: 1957-01-24
Abstract: 837,017. Hydraulic lifting jacks. WEBER, E. Jan. 24, 1957, No. 2637/57. Class 78 (3). An hydraulic jack in which a lifting cylinder 3 moves over a fixed piston 4 is operated by a pump 2 mounted in the upper part of a housing 1 secured to the cylinder 3. The housing surrounds the cylinder, with some clearance, at its lower end and engages the load through an upper surface 37 and a surface 70 mounted on the outside wall. In the form shown the housing 1 is of square section and is attached to the cylinder 3 by a block 12 supporting the pump 2 which is operated by a hand lever attached to a shaft 25. The pump draws fluid from the space between the cylinder 3 and the housing 1, and feeds it under pressure into the cylinder 3. A manually operated discharge valve 19 for lowering the jack and a pressure relief valve are provided. The latter may take the form shown diagrammatically in Fig. 8, where the slide 80 moves to the right as pressure builds up in the lifting cylinder passage 59<SP>1</SP>, until a reduced centre portion 80<SP>1</SP> allows fluid to escape from the pump cylinder 21<SP>1</SP> to the intake passage 51<SP>1</SP>. The jack may be made invertible by providing a second intake pipe above the block 12, which does not completely fill the cross-section of the housing 1, and a rotating or sliding valve to select the appropriate intake pipe. Alternatively the intake pipe may be flexible and have its end weighted down, the gap in the block 12 being sufficiently large to allow the weighted end to pass through. The pump may have two cylinders, one of which may be larger than the other, and one of which may be adapted to become inoperative when a certain fluid pressure is exceeded.

Title: Computing dividers for use in reading off from a drawing rates of heat losses of boundary surfaces
Inventor: WELSH ALEXANDER MARTIN
Filed: 1947-01-28
Abstract: 620,876. Calculating-apparatus. WELSH, A. M., and RAYNER, C. A. M. Jan. 28, 1947, No. 2687. [Class 106 (i)] A proportional divider, for use in reading off from an architectural drawing of given scale the rate of heat loss through a rectangular boundary surface represented on the drawing, bears on at least one arm a series of graduations, each referring to a boundary surface of specified construction, thickness and disposition, and each at a distance from the pivot directly proportioned to the heat transmission coefficient of the boundary surface to which it refers. The legs 1 of the dividers carry adjustable points 9 and to each of the arms 2 are cemented a pair of transparent plates 3 between which may be secured, by a clip 16, a graduated insert, Fig. 3. Each side of a graduated insert corresponds to a particular type of boundary surface, such as a wall of given thickness and construction, and carries graduations, in rows according to the aspect of the wall, corresponding to the heat transmission coefficients of the wall when sheltered or normally or severely exposed. With the relevant graduated insert arranged uppermost between one pair of plates 3, a cursor 6 is aligned with the relevant graduation and a cursor on the other pair of plates is aligned with the first cursor by means of a notch 8 on one cursor which mates with a projection 7 on the other. The points 9 are then arranged to span one dimension of the wall or other surface shown on an architectural drawing and the distance between the projection 7 and notch 8 on the cursors is read by a scale calibrated to give the rate of heat loss, the scale being selected from a series of scales, each corresponding to a particular value of the second dimension, such as the height, of the wall or other surface. Additional graduations may be provided on the inserts to give the additional heat loss due to areas, such as windows, with different heat transmission coefficients, from the remainder of the surface. Instead of providing a series of scales with which to measure the distance between the notch 8 and projection 7, a table may be provided having a scale on one edge and, in columns beneath the scale graduations, the corresponding heat losses for different heights or other second dimensions. The set of values for a given height may be selected by a plate which slides over the table.

Title: Gas for instance air blast electric circuit breaker
IPC: H01H33/835
Filed: 1956-01-27
Abstract: 786,607. Gas-blast switches. AKT.-GES. BROWN, BOVERI & CIE. Jan. 27, 1956 [Jan. 29, 1955], No. 2713/56. Class 38 (5). In a gas-blast switch in which contacts 1, 2 are opened by pressure gas against the bias of a spring 16, electrodynamic forces produced by the circuit current in a conductor loop 9 control the opening of an exhaust valve 8. In the " twobreak " arrangement shown, the conductor loop is formed by rigid members 12 and flexible elements 13, the members 12 being carried by pivoted links 10, 15. The current flowing in the loop causes the members 12 to repel each other and open the valves 8 (one shown) against the bias of springs 17 an amount dependent on the magnitude of the current to be interrupted. In an alternative arrangement, Fig. 2 (not shown), the members 12 release latches to permit the full opening of the exhaust valves by the blast gas, this action occurring when the circuit current to be interrupted has reached a given amount. Figs. 4 to 8 (not shown) illustrate various arrangements in which multi-turn conductor loops are used.
