Title: An improved pulsator for milking machines
IPC: A01J5/10
Filed: 1927-06-02
Abstract: 272,494. Aktiebolaget Separator. June 10, 1926, [Convention date]. Cow-milkers.-In that type of pulsator for milking-machines wherein an oscillating spring-loaded flywheel reverses the piston and valve element controlling the transmission of pressure impulses to the teat cups. the driving-mechanism is so constructed and connected with the flywheel that at the turning points of the oscillating movement the flywheel moves independently of the driving-mechanism. As shown, the flywheel 1 is connected by a spring 13 to an arm 14 on the sleeve portion 17 of a turning piston 15 within a casing 16. The flywheel shaft 2 carries a disc 3 having a pin 4 which, according to circumstances, depresses, or abuts against, resilient pieces 5a, 5b on the control piston 6. Port 8 is connected to vacuum, ports 9, 10 to pairs of milking-elements, ports 7a, 7b to air, and ports 11, 19 to passages 11a, 19a in the casing 16. With the piston 6 in the position shown in Fig. 3, the ports 9, 19 are connected to air and the ports 10, 11 are connected to vacuum; the sides 16<a>, 16<b> of the rotating piston are accordingly connected to vacuum and air respectively, and consequently the piston 15 moves round in the direction of the arrow until it abuts against the surface 20a in the casing. The result is that the flywheel 1 and disc 3 are turned, and so long as it is moving in the direction of the arm in Fig. 3 the pin 4 passes over the piece 5a and the piston 6 is unaffected. When, however, the flywheel reverses its movement the pin 4 engages the front edge of the piece 5a and the piston 6 is moved along to its other position, which is shown in broken lines; the pin 4 then passes over the piece 5b, the ports 9, 19 are connected to vacuum,. and the ports 10, 11 are connected to air, and the piston 15 swings back till it engages the sur. face 20b. The port 19 and passage 19a may bedispensed with, in which case a hole in communication with the atmosphere is provided close. to the surface 20b and the return swing of the flywheel is relied upon for carrying round the piston 15 to engage with that surface. Instead of being fixed to the flywheel and the arm 14 the spring ends may bear upon the two sides of the lug 12 upon the flywheel and that upon the arm, and the spring is then tensioned whichever way the flywheel turns. Instead of a device with a turning piston 15 use may be made of an airmotor with a reciprocating piston, and the reciprocating piston 6 may be replaced by a rotating valve.

Abstract: 1392825 Reduction reacting nickeliferous laterite ore SHERRITT GORDON MINES Ltd 29 March 1972 [3 May 1971] 14897/72 Heading C1A Nickel values, leachable in aqueous solution, are recovered from nickeliferous laterite ore by H 2  reduction roasting the ore in a multiple hearth furnace heated by the partial combustion of fuel in which the H 2  concentration of the gases in the lower half of the reduction zone, supplied by H 2  gas introduced through the bottom of the reduction zone, is >25% (e.g. 30-45%), and the concentration in the gases exiting from the furnace is >3% (e.g. 6-8%), the rate of ore throughput being such that depth of ore on each furnace hearth is 0À05- 0À085 inch for each minute of ore residence time within the furnace; the reduced ore then being cooled (e.g. in a non-oxidizing atmosphere), and recovered, e.g. in aqueous ammoniacal (NH 4 ) 2 CO 3  solution. The ore may be pre-heated prior to reduction in the upper part of the furnace to a temperature of 1250‹ F. at a rate of 35-80‹ F./min. when the ore is a limonite (>40% Fe) or to a temperature of 1350‹ F. at a rate of 35-70‹ F./min. when the ore is a serpentine or garnieritic ore (<40% Fe) and then the ore maintained within Œ25‹ F. of this temperature in its passage down the furnace. The gas temperature across any hearth may #1450‹ F. Air may be injected through a series of nozzles around the periphery of the furnace into the preheat zone to burn the excess reductants contained in the partially combusted fuel gases and thereby control the per cent H 2  in the exit gases. The H 2  is preferably injected in at two points on opposite sides of the lowermost hearth. The hot combustion gases may be injected into the furnace through a plurality of vertically spaced conduits.

Title: Improvements in or relating to circuits embodying cathode potential stabilised picture signal generating tubes
Inventor: MCGEE JAMES DWYER
IPC: H04N5/16
Filed: 1949-06-03
Abstract: 668,643. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 15, 1950 [June 3, 1949], No. 14983/49. Class 40 (iii). Undesired signal excursions in the output of picture signal generating tubes of the cathodepotential stabilized type are utilized to reduce for a predetermined time the electron emission from the target electrode of the tube which gives rise to the undesired signals. The undesired signals, which are produced by the flow of secondary electrons between the target electrode and a tube electrode, which normally serves to collect electron emission from the target, when the target electrode is subjected to a sudden increase in illumination, occur in the blacker-than-black or in the whiter-than-white direction depending respectively on whether the white or a part only of the target electrode is subjected to the sudden increase in illumination and in accordance with the described embodiment these signals are employed to reduce the potential of the tube electrode which normally collects the electron emission from the target to a valve, and for a time, sufficient to allow the electron scanning beam to stabilize the target at cathode potential. As shown in the drawing the tube output signals are supplied to an electronic switch device 22 which is " tripped " by the undesired signals and causes a valve 32 to be rendered conducting so that the potential of the tube electrode 9 (which normally collects secondary electron emission from the target) which is supplied from a resistor 39 in the anode circuit of valve 32 is reduced to a low value determined by the ratio of resistances 37 and 39. After an interval determined by the time constant of condenser 28 and resistor 29 the switch device returns to its normal condition (i.e. in which section 21 is conducting and section 27 non-conducting), valve 32 is rendered non-conducting and the potential of electrode 9 returns to its normal operating valve. In order to reduce the delay time of the time constant circuit 28, 29, so that the grid 26 of section 27 is returned rapidly to its normal condition, a diode 41 is arranged to be rendered conducting as soon as the potential of the anode 24 is reduced, this occurring when section 21 of switch 22 is rendered conducting on the cessation of undesired signals. The diode anode may also be arranged to be driven positive on the failure of either or both of the scanning generators so that the switch device 22 is permanently tripped, producing a reduction in the potential of the tube electrode 9.

Abstract: 619,037. Non-contact-making relays. ELECTRO METHODS, Ltd., BUTCHER, F. E., and WILLHEIM, R. Jan. 17, 1947, No. 14984/48. Divided out of 618,957. [Class 40 (iv)] [Also in Group XXXV] Unbalanced saturation effects occurring in saturable reactor control arrangements are eliminated by providing a short-circuited winding or windings which enforce an equality of voltage across the A.C. windings, exclude residual A.C. voltages across the feed-back circuit, and relieve the D.C. controlling circuit of A.C. components. Fig. 1 shows the winding arrangement of two co-operating saturable reactors (cores, not shown) having opposed A.C. windings 1, 1<SP>1</SP>, feed-back windings 2, 21 (fed .through a rectifier R), and control or signal windings 3, 31 determining the current in a D.C. load L. A winding 6, 61 is applied to each reactor and both are connected in a closed circuit; these windings have substantially no mutual inductance with the A.C. windings. As an alternative, the feed-back windings can be connected in a closed circuit and the D.C. load fed from a separate rectifier, either directly in the output circuit or coupled to it by a transformer as in Fig. 2.

Title: Improved portable elevator
IPC: B65G41/00
Filed: 1954-05-26
Abstract: 766,680. Portable elevators. TEAGLE, W. T. Oct. 22, 1954 [May 26, 1954], No. 15576/54. Class 78 (1). The feed end of a portable elevator 1 is adjustable vertically to either of two positions relative to a supporting structure by extending or folding a toggle linkage 53, 54. Springs 59 assist in extending the linkage, a catch 65 and cross-member 62 locking the linkage in extended position. The supporting structure consists of longitudinal and transverse tubes 39, 40, the former carrying a skid 42 and the latter a pair of wheels 41. The structure can be hitched at either end to a tractor by an interchangeable shackle 83, the front mounting being by a yoke 85 which can be held by a stay 86 when out of use and the rear mounting being directly to the tube 39 so that skid 42 is lifted off the ground when in use. The elevator frame consists of a tube 2 to which are secured transverse members 3 provided with slots 6, Fig. 5, by which wooden boards 4 and side guards 7 are mounted for transverse adjustment to suit the size of the articles, e.g. sacks, to be conveyed. The sacks are conveyed by pushers 18, Figs. 1 and 10, on an endless chain 11 passed over sprockets 10 carried by the frame. The pushers 18 are of L-section, the top edge of which may be protected by a slit tube (not shown) held in place by a spring. Buckets 24 for carrying loose material may be attached to the pushers by bracket 25 engageable over the base 19 of a pusher and a spring-loaded catch 26 to retain the bucket on the pusher, the catch being raised to free the bucket. The chain is tensioned by its wheel 10 at the feed end, being mounted on a tube 12a slidable within the tube 2 and spring-urged outwardly, rotation of tube 12a being prevented by a transverse pin engaging slots in tube 2. The other wheel 10 is driven by belt gearing from a petrol engine 27 mounted in a cradle 28 pivoted to the elevator frame and movable towards and away from a belt pulley 31 by a toggle 37 for release of the driving-belt 30. The discharge end of the elevating mechanism is adjustable and for this purpose is mounted by a tube 45 slidable in a socket 44 carried by struts 43 extending from the ends of the cross-member 40 and provided with holes for a locking-pin passed through the socket. A further pin inserted in a hole below the socket is engageable by a pivoted lever 49 for raising and lowering the tube. Alternatively the tube may be raised and lowered by a winch. A pan 69 for receiving discharged sacks is pivoted to the conveyer frame for adjustment by a stay 70 having a number of holes engaging a peg (not shown) from which it is released by pulling a chain 76. The pan may be connected with the elevator frame by folding levers 80, 81, Fig. 8, held collapsed by springs 82 so that upon receiving a sack the weight of the latter extends the levers moving the sack clear of the chain 11.
