Title: Improvements in or relating to remote control systems
IPC: H02J13/00
Filed: 1925-06-12
Abstract: 258,179. Automatic Telephone Manufacturing Co., Ltd., and Remington, C. June 12, 1925. Drawings to Specification. Selective distant control systems; tell-tale apparatus.-Relates to a system for supervising and controlling from a remote point the operation and condition of a number of apparatus units at a substation. The apparatus units, e.g. circuit breakers, are selected by a constant number of impulses which are transmitted over a single line circuit, under the control of a stepby-step switch at the control station, the contacts of the switch being adapted to be marked by selecting keys associated with the circuit breakers. The selection is determined by the position on the impulse train of an impulse of distinctive character consequent upon the marking of the transmitting switch. The selection is checked at the control station prior to the operation of the selected unit by a key common to all the units. When a key is operated to select any particular unit, the impulses in the train prior to the characteristic impulse operate a step-by-step switch at the substation to effect the selection and the subsequent impulses on the train operate a second switch which, after the complete transmission of the impulse train, completes a circuit from a battery at the substation over the impulsing line circuit and the selected contacts of both switches to illuminate a lamp at the control station individual to the operated key and simultaneously prepares the operating circuit of the selected unit over a second line circuit. The operation of the correct lamp checks the selection, and depression of the common key at the control station operates the selected unit. The switches at the substation are held in their operated positions so long as current flows continuously over the impulsing circuit. If, after selection, operation of the circuit breaker is not desired, the switches may be restored to normal by restoring the operated selecting key. The system described is identical with that described in Specifications 252,230, 252,231, 258,012, and 258,178, which are referred to.

Title: Mower
IPC: A01D34/07
Filed: 1959-03-16
Abstract: 905,857. Reaping machines. MASSEYFERGUSON Inc. March 16, 1959 [March 17, 1958], No. 8934/59. Class 6(3). A mower mountable on tractor hitch-links 13, 17 comprises, in combination, a frame 20 mounted on the hitch-links, a cutter-bar 22, a drag-bar 24 pivotally supporting the cutterbar at one end and being pivotally supported on the frame at its other end by means of a horizontal bearing 50, the bearing being mountable at various positions laterally of the frame in order to adjust the cutter-bar transversely. The frame 20 comprises an inverted-U beam 30 having vertically-spaced hingebearings 34, 35 supporting one limb 40 of a further inverted-U frame 21 the limbs of which are bridged by a plate 42 carrying the bearing 50 at one end and a latch 45 at the other, the latch permitting the frame 21 to swing back under excess load. To permit the cutter-bar and drag-bar to be raised about the pivot 50 as an incident to bodily lifting of the mower, the cutter-head 23 is connected by a chain 68, through a bell-crank 69 on the drag-bar and a cable 70, to a lever 73, Fig. 6, which is pivoted to the hitch connection 31 of one of the hitch-links 13. The lever 73 has an abutment 80 engaging under the hitch-link, so that relative movement between the hitch-link and frame 30 upon lifting tautens the cable 70 and thereby tilts the cutter-bar about the pivot 50. Fore and aft canting of the cutter-bar is effected by making the drag-bar in two telescoping parts 55, 56, Fig. 4, having integral upstanding lugs 60, 61 one of which can be turned relatively to the other by the rotation of a cam 64 in a slot 62. The drive is transmitted from the power take-off, through a jointed shaft 94, to a pulley 91 and belt-drive 92. The bearing 97 carrying the pulley 91 is pivoted on the drag-bar and is adjustable by a turnbuckle 102, the end of the turnbuckle being selectively received in holes 104 in a plate 105 welded to the drag-bar; jockeypulleys 107 are adjustable in slots in the plate 105. A spring 81 counterbalances the cutterbar weight about the pivot 50.

Patent GB-551527-A (GB)
Title: Improvements in or relating to distant control gear for hydraulic apparatus
IPC: B64C25/22
Filed: 1941-07-24
Abstract: 551,527. Hydraulic control systems MESSIER, Ltd., R. O., and CONWAY, H. G. July 24, 1941, No. 9416. [Class 69 (ii)] An electrically controlled hydraulic control sys'em which is especially applicable for operating jacks or aircraft to control the undercarriages &c. is constructed with a control valve box 12, Fig. 1, for directing the liquid delivered by a pump 14 to the required end of the jack so as to move the carriage up or down. The valve 20 which may be a piston or other valve is actuated by energizing one or other of two electromagnets 25, 26 by actuating a lever 36 with push-buttons 34, 35 for closing contacts 38, 39 or 41, 42, and at the same time other contacts are closed to energize an electromagnet 48 which opens a normally closed valve 46 to permit pneumatic pressure from a pipe 43 to be directed to a clutch which drives the pump 14 from the aircraft engine. The valve 46 is held open by a spring- controlled latch 66 which is released by energization of an electromagnet 65 when the carriage has completed its movement in either direction and pressure builds up and operates a piston 59 causing closing of contacts 62, 63. When the latch 66 is released the magnet 65 is automatically de-energized by the breaking of contacts 72 by the motion of the core 70. For control in emergencies a hand-pump 73 supplied by a reservoir 74 can be used to direct liquid under pressure to a pipe 78 which is directed by a shuttle valve 81 to the jack and thus lowers the undercarriage, the pressure fluid passage from the pump being cut off and a by-pass valve 84 opened to connect the lower end of the jack cylinder to exhaust. In a modification the clutch for driving the pump 14 is controlled by a spring toggle device actuated by electromagnets energized similarly to the magnet 65 by pressure-actuated contacts 62, 63. In a further modification, Fig. 3, the pump 14 is driven continuously but is normally by-passed to exhaust via an outlet 109 of a chamber 100 fitted with a piston valve 103 held by a spring-plunger 107 against the action of a spring 104. The plunger can be withdrawn by energize ion of a magnet 110 and the spring then raises the piston 103 so as to cut off the by-pass. The magnet 110 is de-energized automatically, and the plunger 107 then engages a groove in the piston 103, and holds it raised until the rise in pressure at the end of the movement of the jack overcomes the action of spring 108 on the plunger 107 and the piston valve is forced down to the position shown in Fig. 3, thus again by-pasing the pump. Specifications 492,300 and 544,493, [Group XXXIII], are referred to.

Title: A dissipative load and wattmeter for ultra high frequency electric power
IPC: G01R21/00
Filed: 1943-06-11
Abstract: 587,616. Testing short-wave generators. MOULLIN, E. B., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 11, 1943, No. 9484. [Class 40 (v)] [Also in Group XXXVI] A power dissipation device and power meter comprises a transmitting aerial capable of radiating short-wave power as it would in free -space, and enclosed in a box of such construction that it absorbs the radiated power without reacting upon the aerial. The dipole 1, fed from a generator through a line 2, is enclosed in a cylinder 3 of resistive material which is itself surrounded at a quarter-wave distance by a metal cylinder 5. By proper choice of the resistivity of the cylinder 3, the whole of the power radiated is absorbed, as described in Specification 585,460. A thermometer within the box,. e.g. a thermocouple 8 connected to a meter 7, indicates the - radiated power. For calibrating the meter 7, a known steady current can be passed through the tube 3, which is provided with copperplated end-caps 4 led to terminals 6 for this purpose. The heat capacity of the tube 3 can be kept low by making it of paper impregnated with colloidal graphite and it may be protected from moisture by soaking in melted paraffin wax or wax of higher melting point. If the device is used for dissipating power without measuring it, the tube may be of more robust construction with carbon or other material painted on its surface. The cylinder 5 may be constructed of thin rods arranged as a diamond mesh network so that its radius may be adjusted for the purpose of matching the impedances of the load and the feed cable 2 ; and it may be enclosed for mechanical protection in a light metal drum. The device is particularly intended for use in testing and adjusting short-wave generators.

Title: Improvements in or relating to apparatus for heating and deaerating water
IPC: B01D19/00
Filed: 1949-04-07
Abstract: <PICT:0660709/III/1> Apparatus for heating and deaerating water in particular boiler feed water by means of steam includes a tank, a vent therein for the escape of non - condensible gases, a combined mixing and atomizing nozzle disposed in the tank and connected to the steam inlet, one wall of the nozzle having a water inlet of venturi shape forming a throat to reduce the steam pressure at that point so that the water may enter the nozzle, flow obstruction means preferably being provided in the nozzle to produce a thorough mixing of water and steam.  In the form shown boiler feed water enters the tank 1 through jets 3 in transverse pipe 2 and is directed against baffles 4, 6, 7 from which it falls into a pan having an opening 26 in its bottom wall 12 through which the water flows into a chamber formed above an inclined section 22 of a steam nozzle.  Steam, entering the tank through the inlet 20, passes downwardly through the vertical section 21 of the nozzle to the inclined section 22 which in cross-section is shaped like a venturi tube and which has a water inlet 30 at the lower end of its upper wall and incorporates a baffle member 31.  Water drawn through the inlet 30 is forced against the baffle 31, through the restricted port 32 and is broken up and mixed with the steam.  If, under heaving loading, water overflows from the collecting chamber formed above the inclined section 22 of the steam nozzle, it is caught and atomized by the stream of mixed steam and water issuing from the nozzle outlet 23.  Non-condensible gases escape at the top of the tank through the vent pipe 13 which is described in Specification 638,627.  Hot water is pumped out through the outlet 33.

Abstract: 434,583. Flexible-unjointed hinges. ANDRE (SILENTBLOC), Ltd., and JELLEY, S. W., Victoria Gardens, Ladbroke Road, Notting Hill Gate, London. March 27, 1935, No. 9555. [Class 65 (ii)] In a flexible joint or support of the kind comprising an outer member A with a cylindrical bore, an inner member B and a rubber or like bushing D permanently disposed between the two members under radial compression so as to adhere to them, the inner member B having an annular abutment B<1> while the outer member A has an annular abutment A<1> for preventing displacement of the rubber and transmitting axial thrusts, the rubber-engaging face of the inner abutment B<1> has an axial cross-section curved or inclined to the axis of the joint so that its outer circumferential portion lies further from the end of the rubber bushing than its inner circumferential portion. The end of the rubber bushing adjacent to this abutment is preferably similarly curved or inclined in the opposite direction. This arrangement provides a gradually increasing contact area between the abutment and bushing as the axial thrust increases, and allows greater axial movement of the parts. With a similar object the other end of the bushing is preferably curved or inclined in axial section so that its outer circumferential portion is normally further from the centre of its length than the inner portion, and the outer abutment A<1>, with which it engages, is suitably shaped to give a progressively increasing contact area and its outer circumferential portion is formed as an annular channel to receive an annular rib on the corresponding part of the rubber bushing, as shown. Relative movement of the parts on release of any axial load is limited, in the form shown, by an abutment B<2> and rubber washer C on the member B engaging the outer abutment A<1>. Two such joints may be combined end to end in opposed relation, to oppose axial forces in both directions, with common outer and inner members, the inner abutments being either at the ends or the centre of the combined device with the outer abutments arranged accordingly.
