Title: An improved automatic double acting reciprocating pumping apparatus operated by liquid or air under pressure
IPC: F04B9/115
Filed: 1933-01-17
Abstract: 418,283. Deep - well pumps. BRIND, W. G., Imperial Reserve, Mafeking, South Africa. Jan. 17, 1933, No. 1528. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 7, 1933]. [Class 102 (i).] A deep-well pump comprises two pistons 30, 31, Fig. 4, connected by a rod 32 passing through a partition 7 containing valve mechanism, which distributes operating water or compressed air to the inner surfaces of the pistons. The outer ends of the cylinders are provided with valve boxes having suction valves 26, Figs. 4 and 8, and discharge valves 27. Each valve box comprises a chamber 54, which communicates with the cylinder space through axial passages 28 and with the discharge passages through lateral ports 29. The lower pump space 52, draws through a strainer 64 and discharges to an annular space 21, which communicates with an upper annular space 20 through a passage 19, Fig. 23, through the partition 7. The space 20 communicates with the rising main by means of a passage 47. Operating fluid is supplied, either direct to the partition 7 by a pipe outside the rising main, or by a pipe inside the rising main. In the latter case it passes through a port, not shown, in the upper cylinder head 3 to an annular space 4 and so to ports in the partition 7. The latter is provided with a semi-circular recess 15, Fig. 23, communicating with the upper cylinder space 13, and with a similar recess 16 communicating with the lower cylinder space 14. The recesses have ports 9, 10 for the admission of motive fluid, and exhaust ports 17, 18 to the passage 19. The ports are controlled by valves 11, 12, Fig. 28, of L-section, the valve 11 being in the recess 15 and the valve 12 in the recess 16. The valves are connected by a bridge piece 43 and are operated by an arm 42 on a sleeve 37, Fig. 27, the arm being grooved to engage a rib on the valve 11. The sleeve 37 has a slot which is engaged by a rib 81 inside a surrounding sleeve 36. The latter is connected by a spring 74 to an outer member 35 comprising upper and lower rings connected by an axial portion. A lug on the member 35 engages a helical slot 78, Fig. 26, in the interior of a stationary cam member 34, and a lug on the sleeve 36 engages an internal cam projection 79 in the member 34. The sleeves 35, 36 are moved downwards by the piston 31 and upwards by a frame 39, 40, 53 operated by the lower piston 30. On the upward movement the lugs on the members 35, 36 are drawn together by the action of the slot 78, thus putting the spring 74 in compression. When the lug on the sleeve 36 passes above the cam 79 the spring moves the lug to the left and on the downward stroke the lug moves along the left hand edge of the cam 79 and the spring 74 is put in tension. At the bottom of the stroke the spring moves the lug to the right. The oscillating movements of the sleeve 36 are communicated to the sleeve 37 and so to the valves 11, 12.

Title: Harvester spout control system
IPC: A01D43/073
Filed: 1974-01-14
Abstract: 1428601 Controlling harvesters DEERE & CO 14 Jan 1974 [15 Jan 1973] 01578/74 Heading. A1F [Also in Division G3] The lateral disposition of a discharge spout 26 on an agricultural harvester 12 is controlled by a system consisting of an electrical circuit Fig. 2 a first part 42, 44 of which; is attached to a trailer 14 into which crop is discharged from the spout 26; and generates an alternating magnetic field 46. A second part 48 to 56 of the circuit comprises: a sensing coil 48 positioned in the magnetic field and attached to the discharge spout 26, by which the orientation of the spout, relative to the magnetic field, may be sensed; and an actuator which moves the spout laterally, according to signals received from a phase detector 52 which compares the phase of a reference signal supplied by the first part of the circuit against that of the signal coming from the sensing coil 48 in the second part of the circuit. In one embodiment Fig. 2 the first and second parts of the circuit are physically connected by a lead 66 along which the reference signal is passed. In a further embodiment Fig. 3 there is no physical connection between the first part 42A and 44A, and the second part 48A to 56A, and 108 to 120, the reference signal being derived from a second sensing coil 108 disposed in the magnetic field 46 orthogonally to the first sensing coil 48A and similarly attached to the spout 26.

Title: Improvements in hydraulic shock absorbers for automobiles
IPC: F16F9/28
Filed: 1932-01-19
Abstract: 393,689. Preventing lateral tilting; hydraulic shock-absorbers. HOME, H., 30, Akazienallee, Essen, Germany. Jan. 19, 1932, No. 1604. [Classes 108 (ii) and 108 (iii).] In hydraulic apparatus for preventing lateral tilting of the frame of a vehicle relative to the axle, in which shock-absorbing cylinders on opposite sides are cross-connected by pipes, two independent cylinders are arranged adjacent one another on each side of the vehicle and freely movable pistons are operated by a double-armed lever connected to the axle. A unit comprising two inclined cylinders, as shown in Fig. 2, is arranged on each side of the vehicle, each of the freely moving pistons g, h being forced into its cylinder by the twoarmed lever k connected by an arm l and link m to the axle. The pistons are raised by fluid pressure from corresponding cylinders on the other side of the vehicle. When the piston g on one side is forced into its cylinder by the approach of the frame and axle to one another, liquid flows freely through the valve n and pipe p, Fig. 4, so as to raise the piston h in the corresponding cylinder on the other side and thereby force the frame and axle together on that side so that the two remain parallel. The liquid flows freely from the cylinder to the pipe p, since the pressure in the cylinder forces the valve n along its cylinder against a light spring and uncovers a series of ports. When the frame and axle tends to move apart, the apparatus operates in a similar manner, the pistons h then moving into their cylinders, but the movement is hydraulically resisted since the valves n are not then forced upwards and opened.

Abstract: 1,236,192. Cutting webs. U. MAGGIA. 10 Jan., 1969 [19 Jan., 1968], No. 1724/69. Heading B4B. [Also in Division B8] A machine for cutting portions e.g. from continuous fabric T, comprises a continuous support belt 3, a counter belt 10 co-operating in an operating zone to grip the fabric, and cutting means 12 carried by the support belt 3, normally inoperative but capable of being urged into operative position in the operating zone. The belts 3, 10 comprise segments 5 covered by a cladding 6 e.g. of plastics foam, the counter belt 10 being supported by a vertically adjustable carriage 8 on the main machine frame 1. For transverse cuts, a blade 12 is supported by levers 13 pivoted to a preceding segment 5, the levers 13 being raised in the operating zone by impingement on a roller 15 to project the blade 12 through a slot in a segment 5 to cut the fabric T, backed by the belt 10 and rollers 28. The blade 12 is further made to slide longitudinally in a support 16 during cutting by a rod (17), Fig. 4 (not shown), and bell crank (L8) operated by a roller (22) following guides (20), (21). Cut portions are removed from the belt 3 by engagement with spikes 34 depending from bars 33 forming segments of a conveyer belt 31. The portions are drawn along the lower run of the belt 31, Fig. 2 (not shown), until positioned above a receiving unit (32), whereupon plates 36 held in raised position by guides 38 are allowed to drop, pushing the portion off the spikes 34, e.g. on to a pile. For shaped cuts, blades 23, 24, Figs. 5 and 6 (not shown), are provided on a frame 25 which is drawn over the roller 15.

The stack, while under pressure, is repeatedly dipped in 'cleaning agent; and finally baked, to cure the impregnant, in accordance with a specified temperature cycle. The resulting capacitors are housed in moisture-tight casings. Glass-paper may be used in place of mica for the insulating sheets 14, 15.
