Abstract: 514,416. Loom picking-mechanism. CAMPS, J. P. May 6, 1938, No. 13547. Convention date, May 11, 1937. [Class 142 (iii)] Picking motions; picking sticks; checking picking sticks.-The picking-stick 22 can slide endways in a member 15 and carries a roller 20 moving in a curved slot 11a which causes the upper end of the stick to move in a straight line. The slot 11a is in a bracket 11 secured to and oscillating with the slay 27. The member 15 is mounted to be oscillated in the bracket 11 to effect picking by a cam 4, a two armed lever 9 mounted at 10 on the loom frame and a two armed lever 13 mounted at 14 on the bracket 11. An adjustable spring 37 returns the picking stick. At the end of the picking stroke the stick is checked by a torsion rod 29 which is connected with the member 15 by a coupling 30 which allows freedom up to the end of the picking stroke.

Abstract: 346,593. Thermostats ; electricallyactuated valves. NEILSON, T. and MARSHALL, J., 11, Cogan Street, Pollokshaws, Glasgow. May 7, 1930, No. 13999. [Class 135.] In a thermostatically controlled heating or cooling system for ship's cabins, storage chambers or buildings, a number of mercury thermometers 6 .. 10 are mounted in a perforated casing 5 in the space to be heated or cooled. Each thermometer is provided with a fixed contact wire 20, and with an adjustable contact 6a .. 10a projecting into the bore at the top. The latter contacts 35, Fig. 2, may be adjusted in the bore 36 by a rack 33 and pinion 34, to a predetermined range of temperatures. The contacts are connected to a multiple point switch C, by which any thermometer may be selected and placed in the circuit 17 of a relay D, which controls electromagnetically operated valves A in the circulating system of the heating or cooling fluid. The temperature in the space is thus regulated to the setting of the adjustable contact of the thermometer selected. Specification 343,310 is referred to.

Abstract: 887,714. Electromagnetic relays. SMITH & SONS (ENGLAND) Ltd., S. May 2, 1958 [May 2, 1957], No. 14048/57. Addition to 787,391. Class 38 (5). A relay having a coil 19 on an aluminium former 18 movable in the gap 5 of a magnetic circuit similar to that of the parent Specification has coils 11, 12 on the part of the magnetic circuit which includes the armature 21 so as to influence the yielding restraint on the movement of the rod 14 on which the former 18 and armature 21 are mounted. The rod 14 is biased to the position shown by a spring 17 and normal energization of the coil 19 retains the former in the gap 5 against this spring force. A reduction of the current in the coil 19 allows the spring to overcome the magnetic attraction of the coil and of the armature 21 so that the rod " snaps " to the position shown, closing the contacts 22, 23. The relay may be reset, if the current in the coil 19 is sufficient, by momentary energization of the coils 11, 12 to attract the armature 21. Alternatively a steady current may be passed through the coils 11, 12 to change the value of the relay operating and release currents.

Title: Shock absorber
IPC: F16F9/34
Filed: 1949-05-26
Abstract: 659,160. Hydraulic shock absorbers. GABRIEL CO. May 26, 1949, No. 14098. Convention date, June 15, 1948. '[Class 108(iii)]  In a hydraulic shock absorber having a cupshaped piston through the closed end of which extends a passage 23, the inner end of which is normally closedby a spring-pressed valve 40, there is provided a bleed passage 33 extending through the closed end of the piston, and a  closure means in the open end of the piston including a normally closed valve 43 arranged to have opening movement in a direction away from the closed end of the piston, so that when the piston moves in a direction towards that end of the cylinder which is nearer to the closed end of the piston, the closure means valve 43 and the spring-pressed valve 40 open successively, the bleed passage 33 and closure means valve 43 maintaining a positive hydraulic pressure in the piston space between the two valves 40, 43 prior to the opening of the spring-pressed valve 40. The closure means valve 43, in the construction shown, comprises a flexible disc which is clamped by the head of a pin 37 and a washer 44 to the face of a spider 35a carried by sleeve 35 threaded in the open end of the piston. An enlarged portion 38 of the pin 37 clamps a cup-shaped member 42 to the spider 35a to form a housing for a spring 41 which loads the valve 40 against its seat. The latter is formed by the end of the piston rod which is threaded thereto to the piston so as to clamp a ring 29 and cup-shaped member 30 thereto. The ring 29 retains a flexible packing ring 28. Circumferentially-spaced axially-extending grooves 31 in the piston periphery connect the cylinder space below the piston with an annular recess 32 in the piston periphery. Operation. On compression, liquid flows upwardly through the grooves 31 and deflects the packing ring 28 to pass to the space above the piston. Both valves 43, 40 remain closed. On recoil the packing ring 28 is forced into sealing engagement with the cylinder bore. Pressure above the piston is transmitted by the bleed passage 33 to the space within the piston so that the pressure differential on either side of the valve 43 is initially greater than that corresponding to the valve 40. The valve 43 thus opens before the valve 40. Air which collects beneath the piston can again become entrained in the liquid within the bore 26 before the valve 40 opens, thus avoiding the hissing noise due to separated air rushing through the valve 40 and consequent formation of foam and emulsification of the liquid.

Abstract: 846,427. Vehicle jacking arrangements. BOUET, B. May 2, 1958 [May 3, 1957], No. 14117/58. Classes 79(2) and 79(3). Jacking devices fitted with auxiliary driving wheels 1,2 to facilitate parking &c. by transversely moving one end of a vehicle, have means tc selectively orientate the wheels 1, 2 so that their axes 7, E Fig. 1 intersect at turning centres 9, 10 immediately above the zone of contact of one of the wheels 10, 12 at the opposite end of the vehicle. In the example of Fig. 1 the wheels 1, 2 are steered between the two positions by a lever 19 coupled to steering arms 20, 21 through cables 13, 14 acting against return springs 22, 23. In another example the wheel forks 37 are mounted on telescopic legs each comprising a hydraulic jack 27 articulated to the vehicle on a pin 28 and actuated between the raised horizontal position and the lowered vertical operative position by a second hydraulic jack 30. Control valves actuated by levers automatically selectively operate first the jacks 30 to lower the wheel 1 and then the jacks 27 to raise the vehicle off the ground. Spring loaded plungers 50, 51 releasable by hydraulic pressure and engaging apertures in the telescopic legs operate to lock the legs in the vertical and horizontal positions. In this example the wheels are steered between the two positions by opposed hydraulic jacks 46, 47 Fig. 3 engaging a projection 43 on a rotatable ring 42 connected to the wheel fork 37 through a sliding pin 40. The wheels 1, 2 are driven from the brake drums 64 Fig. 6 of the rear wheels 24 through friction rollers 60, reduction gear 57 and flexible cables 61. The rollers 60 are engaged with the drums 64 by hydraulic plungers 54 to which pressure is supplied from a pedal operated plunger 74 (not shown).

Abstract: 112,615. Eustis, F. A. Jan. 12, 1917, [Convention date]. Alumina; potassium and sodium aluminates; aluminium, chromium, cobalt, manganese, and nickel sulphates.-Iron ores containing aluminium, with or without other metals such as nickel, cobalt, manganese or chromium are treated for the removal of the whole or a substantial part of the aluminium; the remaining ore may be subjected to a sulphatizing roast to render soluble a large proportion of the incidental metals and the remaining aluminium, if any, but only a small proportion of the iron, or the residue may be smelted after the removal only of the aluminium. The aluminium may be removed from the ore by treatment with sodium or potassium hydrate or sodium carbonate, and precipitated from the resulting solution by a mineral acid or by the addition of aluminium hydrate. The sulphatizing of the ore residue may be effected by roasting at about 460‹ C. with 5-10 per cent of sulphurbearing material, or by heating with sulphur dioxide and a small amount of air at about 460‹ C. The mass is then leached with water or dilute acid, and the solution treated by precipitation or otherwise to recover the metals, the iron-bearing residue being afterwards smelted.
