Title: Improvements relating to sway braces for pipes and the like
IPC: F16L3/205
Filed: 1956-05-02
Abstract: 792,093. Spring units. BERGEN PIPESUPPORT CORPORATION. May 2, 1956 [May 3, 1955], No. 13522/56. Class 108(3) ' A sway brace for piping comprises a housing consisting of relatively slidable first and second units 11, 12 each including spaced first and second end walls, the first end wall of each unit being disposed between the end walls of the other unit resilient means 45 interposed between the first end walls of the units 11, 12 and normally acting to effect retraction of the brace and means 46, partly in and slidable with respect to the housing, and movable in opposite directions, in one of which directions it engages the unit 12 and effects extension of the brace. As shown, the unit 11 comprises diametrically opposed arcuate side portions 15, 16 rigid with first and second circular end walls 13, 14. The end wall 14 has connection lugs 18. The unit 12 comprises diametrically spaced arcuate side portions 22, 23. rigid with first and second circular end walls 20, 21. A coiled spring 45 acts between an annular member 42 adjacent the wall 13 and a similar member 40 which is internally screw threaded and carried by a screw threaded sleeve 37 rigid with a bolt 36 adapted to be turned by means of a suitable tool from outside the housing. Thus the pre-load of the spring 45 may be varied. The axial position of the member 40 relative to the housing is indicated by means of a pin 41 which projects through a slot 27 in the housing to give a reading of load on a scale 31. A similar pin 44 is carried by the member 42 and projects through slot 26 to furnish a reading relative to a second load scale 28. The piping (not shown) is connected to a rod 50 which is rigid with, but axially adjustable in relation to, a plunger 46 carrying a head 48. Under no-load conditions, the plunger 46 is urged by the spring 45 acting through member 42 on the head 48, into a position in which the head 48 engages with the end wall 21. In operation, when a tension load is applied between the rod 50 and the lugs 18, the end wall 13 picks up the member 42 so compressing the spring 45 and causing retractive movement between the units 11. 12. When a compression load is applied the head 48 picks up the member 42 and applies compression to the spring 45 and relative retraction occurs between the members 11, 12. In a modification (Fig. 5, not shown), the axially adjustable member 40 is dispensed with, and the spring 45 at this end bears directly on the end wall 20. The threaded sleeve 37 is replaced by a plain sleeve which is rigid with the end wall 20, and is of sufficient axial length for it to serve as a guide for the plunger 46.

Title: Improvements in and relating to cinematograph projectors
IPC: G03B21/18
Filed: 1948-05-19
Abstract: 649,653. Kinematograph projectors. KEMP, C. H., and LIDDELL, R. May 19, 1948, No. 13555. [Class 97 (i)] A projector includes separate switches for the driving-motor and projection lamp, a common control means for closing the switches in sequence and opening them, and means automatically responsive to a decrease in film tension or loss of a film loop, for opening them. A switch for a sound reproduction exciter lamp may be included in the middle of the switching sequence. In the form shown, two overlying bars 5, 15 are both slotted to be slidable lengthwise on mounting studs. The face of the bar 5 has alternate recesses and raised portions 5a, 5b, 5c, 5d and on this face bear the operating buttons, indicated at L, M, E of switches for projection lamp, motor, and exciter lamp respectively. As the bar 5 moves to the right the button M rides on to the raised portion 5b to close the switch. Then the buttons E and L drop, in sequence, into the recesses 5c, 5a, respectively, to close these switches. At each stage of the movement a tooth 12a, on a latching lever 12 pivoted at 13, engages behind one of the pins 14 on the bar 5. The movement of the bar 5 is produced by a knob 8 rotating a shaft 9 carrying an arm 10 acting on a pin 11 projecting from the bar and serving also as an anchorage for the spring 18, anchored also at 20. To stop the projector the knob is rotated in the opposite direction so that the arm 10 bears on an abutment 15a at the end of the bar 15, a projecting pin at the other end of the bar engaging the end face 12b of the lever to lift the tooth 12a clear of the pins 14 to allow the spring 18 to return the bar 5. Loss of the film loop between the projection gate 22 and the sprocket 24 is detected by a feeler 30 on an arm 28, which, when lifted, rotates the shaft 29 to lift the arm 31 which lifts the lever 12 by engaging a projecting pin 32. The arm 31 normally rests on the end pin 14 and in the " off " position the feeler 30 acts as a loop forming member for film threading. When the bar 5 is moved in switching the projector on, the feeler is lifted off the film. Between the sound drum 25 and the take-up spool the film passes over a roller 26 on an arm 33 mounted on a spindle 34 carrying a disc acted on by a spring 39. If film tension is lost the disc rotates and a pin 36 engages a notch 37a in a lever 37 carried on the lever 12, whereby the latter is lifted to stop the projector. Specifications 649,698, [Group XXXVIII], 649,699 and 649,700 are referred to.

Filed: 1948-05-24
Abstract: 646,609. Change-speed chain-gear. GIANNELLI, U. May 24, 1948, No. 13949. [Classes 80(i) and 80(ii)] A spring-loaded block C, carrying a chain - tensioning sprocket or pulley A in a multi-sprocket chain-shifting gear on a cycle, is positively locked in adjusted positions on a fixed square - s e c - tioned bar D on which it slides, by a pair of opposed pawls E, E, pivoted in the block and spring- loaded into engagement with ratchet-teeth on the bar. To effect a shift, the pawls E are first both lifted out of engagement by a control lever, the block then being under the influence only of its compression or tension loading-spring, not shown, which permits the chain to be shifted onto a selected hub-sprocket. by a striking fork, Fig. 3, not shown, controlled by a separate lever. The spring ensures the correct position of the tensioning-block C in the new speed, after engagement of which the pawls E are released to lock the block. The ends of the support-bar D are fixed to the lower end of the seat-tube or to the chain- and seat-stays of the cycle-frame, with the tension-pulley A above or below the centre line of the driving and driven sprockets. The loading-spring is capable of maintaining drive-tension on the chain with both pawls E disengaged. The pawls are offset so that only one engages at once. The device may be used with fixed or freewheel driven sprockets, in which former case it permits back-pedal braking.

Title: Means for increasing the drive power of a piston and for controlling the return thereof
IPC: F15B15/20
Filed: 1962-04-11
Abstract: 930,364. Stapling machines. SENCO PRODUCTS Inc. April 11, 1962 [Feb. 14, 1962], No. 14000/62. Class 89 (3). A pneumatic stapling machine comprises a piston 28 movable in a cylinder 21, during a working stroke, from an initial position to a final position, by compressed air controlled by a valve 45, a reservoir 50 to receive pressurized air in order to effect the return of the piston to its initial position after the pressure of the driving air has been reduced, a port 52 which introduces compressed air into the reservoir only after the piston has completed its working stroke, ports 51 for communicating the reservoir with the cylinder in order to return the piston, and passage means 55 to exhaust the air moved by the piston during its working stroke from the machine. The compressed air is fed via a port 27 into a chamber 26, which, when a trigger-operated valve 40 is actuated, communicates, via the valve 45, with the cylinder 21. The air then acts on the piston. 28 and forces it downwardly, the air in front of it being exhausted through the passages 55 formed in a resilient stop 33, and the passage 24 formed in a guide 22 for the staple driver 29. The exhaust is prevented from entering the reservoir during the downward stroke by means of an 0- ring 57 which is urged into contact with a seat 56 formed in the cylinder 21, by air passing through the ports 51. When the piston reaches the resilient stop 33, the driving air enters the reservoir via the port 52 which is controlled by a valve 53 loaded by a spring 54. Upon release of the valve 40 to cut off the supply of air to the cylinder, the pressure built up in the reservoir returns the piston to its initial position where it is retained by means of a magnet 36. In the modification shown in Figs. 7 and 7a, compressed air fed into a chamber 63 in the machine, normally maintains a spring-loaded valve 66 in a closed position. Upon operating a trigger 39, a valve 80 is actuated which cuts off the supply of air to the top of the valve 66 which then opens and permits air to act on the piston 28. The air in front of the piston during the working stroke is exhausted via passages 51, 75, a valve 70 and ports 76, the valve having been moved by the compressed air to a position wherein the exhaust air is prevented from entering the reservoir 50. On completion of the working stroke, compressed air is fed into the reservoir via the ports 53. Upon release of the valve 80, the valve 66 closes, thus cutting off the supply of air to the top of the piston and to the valve 70. The air in the reservoir then acts on the piston via an annular recess 72 in the valve 70, and a port 75, 51 to return the piston to its initial position where'it is retained by a magnet 36a. Specifications 779,042 and 894,840 are referred to.

Abstract: 1383807 Electrostatic separation of sylvine and kieserite from rock salt KALI UND SALZ AG 24 March 1972 14017/72 Heading C1A Sylvine and/or kieserite is separated from crude argillaceous rock salt containing sylvine and/or kieserite by subjecting a finely divided mixture of the crude rock salt and a conditioner which is either 2,6-dinitro phenol or a mixture of 2,6-dinitro phenol, a halocarboxylic acid and water, to electrostatic separation into a clayrock salt fraction at the positive electrode and a sylvine and/or kieserite fraction at the negative electrode. Suitably the dinitrophenol is used in amounts of 50-500 gms./tonne of crude salt, the halocarboxylic acid, e.g. a chloracetic acid in amounts of 50-500 and water in amounts of up to 4000 g./t. The mixture is preferably intensively mixed for 10-120 sees. and then subjected to electrostatic separation at 25-65‹ C. and a relative humidity of 2-20%. The sylvine and/or kieserite fraction collected at the negative electrode may thereafter be purified by flotation. Examples describe the separation of a sylvine and kieserite fraction and a clayrock salt fraction from a crude rock salt comprising mainly NaCl, KCl and MgSO 4  and a few per cent clay using the above conditioners; in comparative experiments there are used as conditioners, a fatty acid, o-cresol, and mixtures of lactic and trichloracetic acids with-or without ocresol.
