Title: Improvements in electrical indicating systems
IPC: G01F23/44
Filed: 1952-10-13
Abstract: 723,949. Electric indicating systems. SANGAMO WESTON, Ltd. Oct. 13, 1952 [Oct. 15, 1951], No. 25618/52. Class'40 (1). Apparatus for indicating the level of a liquid comprises two circular potentiometers, one in each of two interconnected bridge circuits, arranged so that the full scale reading of the indicator of one bridge is equal to one unit reading of the other bridge, the larger indicator pointer moving in discrete units as the more sensitive indicator pointer falls below zero of goes beyond the full scale indication. Movement of a float F (Fig. 2) on a liquid L causes rotation of the slider 15 of a potentiometer 16, and a geared rotation of slider 17 of a second potentiometer 18. The slider 15 can make a plurality of rotations, the wire of potentiometer 16 covering 360 degrees with a small open-circuit portion. The potentiometers 16, 18 are included in two DC bridge circuits (Fig. 1) having moving coils 43, 55 respectively in the diagonals to indicate the unbalance currents on meters 44, 33 respectively, the former diagonal containing a bucking coil 56 coupling with the moving coil 55 of the second diagonal, the coupling being such that as pointer 46 of meter 44 moves from zero to full scale, the unbalance current in bucking coil 56 opposes the increase in current in moving coil 55, and maintains the pointer 36 of meter 33 stationary. At the ends of the scale of meter 44 slider 15 of potentiometer 16 is open-circuited and the pointer 36 of meter 33 jumps to the next discrete unit indication.

Patent GB-819372-A (GB)
Title: Improvements in and relating to coin-freed prepayment mechanism
Inventor: ASH FRANK STANLEY
IPC: G07F15/12
Filed: 1956-08-22
Abstract: 819,372. Coin-freed apparatus. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. Nov. 22, 1957 [Aug. 22, 1956], No. 25660/56. Class 27 A prepayment mechanism controlling, for example, a television receiver on a time basis or for charging for quantities of a commodity such as gas, water or electricity comprises a displaceable coin holder 3 having pockets in which the coins are held with their edge protruding so that, on movement of the holder, the'edge acts as a cam surface to operate a displaceable member connected to one side of a differential mechanism the other side of which is connected to a timing device or meter. For bi-coin operation, a casing 1 has two slots 5 provided with a gauge plate 2 for testing for excess diameter and thickness and in line with the slots the rotatable holder 3 has pairs of diametrically-opposite slots 4 and 5 for shillings and sixpences respectively, the shilling slots 4 each having an extension 4a so that sixpences inserted by mistake are diverted out through a slot Sl. Opposite each pair of slots, two double star wheels 14, 15 and 14a, 15a are independently journalled and geared to the sun wheels 22 and 23 of a differential 24, the gear ratio for the shilling star wheel being twice that of the sixpence star wheel and the planet carrier shaft 21 of the differential 24 being connected through a differential 26 to a tripping cam 28 and to a timing or measuring- out shaft 30. In operation, assuming a shilling is inserted in the slot 4, and the holder 3 is rotated by a knob 13, the edge of the shilling will engage a tooth of the thick star wheel 14 and as the wheel is thus rotated a tooth of the thin star wheel 15 will engage in a notch X in the coin holder so that the rotation of the holder will be imparted directly to the wheel. The star wheel is located in its moved position by a leaf spring 35 and the holder is located in position for the next operation by one of two pins 31 engaging in a notch 38 in a spring-loaded lever 32; the notch 38 and pins 31 are shaped so that reverse movement of the holder is prevented and the lever has a latch abutment 39 which, once the holder has started to be rotated, prevents return movement until the coin has reached a position at which it will operate the star wheel. In a modification, the star wheels are replaced by ratchet wheels 42 each advanced by a pawl 50 on a spring-loaded lever 41 pivoted either on the ratchet wheel shaft or independently, the coin moves the pawl from one tooth to the next and when the lever is released its spring returns it to advance the ratchet by one tooth space.

Title: Load handling apparatuses
IPC: B66C23/00
Filed: 1975-06-17
Abstract: 1482227 Luffing arm apparatus FORALKRANAR AB 17 June 1975 25793/75 Heading B8H A load handling apparatus comprises a frame (1), Fig. 1 (not shown), a head 2 mounted on the frame for rotation about a vertical axis, an arm, formed of inner and outer portions 3, 4, pivotally mounted on the head for movement in a vertical plane and a load holder 5 mounted on the free end of the arm. The inner portion 3 of the arm comprises parallel links 7, 8 connected at their ends, through joints 9-12, by inner and outer links 14, 13 to form a first parallelogram and a third link 15 parallel to links 7, 8 and pivotally connected at its ends to a connector 21 and to a rack 17. The outer portion of the arm comprises an extension 23 of the link 13 and a parallel link 24 connected at their ends, through joints 11, 21, 26, 27, by the connector 21 and the holder 5 to form a further parallelogram whereby the attitude of the holder 5 remains constant regardless of the inclination of the arm. The pivot 12, between the links 8, 14 is mounted on the rack 18 which is vertically guided between guides 16, 17 and in mesh with a driven sprocket 19 to effect its vertical displacement. A pair of rollers 29 are mounted on the other link 7 of the inner arm portion and are guided by horizontal-rails 30, 31 whereby if the pivot 12 is positionally fixed then the holder will execute a horizontal translatory motion on manual shifting of the holder 5. Similarly if the rollers 29 are stationary, then movement of the rack 18 will result in a vertical translatory motion of the holder. The rollers 29 may be replaced by a motor driven rack to effect horizontal translatory motion of the holder. The link 8 has an extension to which a counter weight 34 is attached substantially in alignment with the axis of rotation of the head 2.
Patent GB-851991-A (GB)
Title: Recovery of uranium values from uranium-bearing raw materials
IPC: C22B60/02
Filed: 1952-10-15
Abstract: <PICT:0851991/III/1> Finely divided uranium-bearing materials are leached in aqueous sulfuric acid together with manganese dioxide in an amount sufficient to oxidize the uranium to the hexavalent state. The dissolved uranium may be subsequently precipitated in known manner.  The leaching may also be effected in the presence of a minor quantity of ferric ions supplied, for example, as ferric sulfate. According to Examples (1) an ore bearing uranium and gold was crushed and the gold values were extracted with aqueous sodium cyanide and the residue was treated as shown in the Figure. The ore was fed to an agitator 1 and pulped with overflow liquor from a thickener B to form a slurry having a pH of 3.5, thereby precipitating any ferric ions: the liquor from the thickener B contained the solubilized uranium values and was partially neutralised by the incoming ore.  The slurry was passed to a thickener A and the overflow containing the uranium passed to a precipitator with associated thickener F where the uranium was precipitated by magnesium oxide at a pH of 6.5.  The barren solution from the thickener F was returned as washing liquor to the extraction process.  The underflow from thickener A was treated with sulfuric acid and manganese dioxide in a vessel 3 and passed to a thickener B from which the overflow, containing the dissolved uranium, was recycled through thickener A for passage to the precipitating unit.  The underflow was washed countercurrently with barren liquor in thickeners C, D and E. Small quantities of iron are provided by naturally occuring silicates in the ore and by metallic iron formed by the abrasion of machinery.  (2) A uranium ore was wet ground and adjusted to a 60% solid slurry; sulfuric acid together with manganese dioxide and a minor amount of powdered iron were added thereto.  The slurry was agitated at ambient temperatures and then filtered thereby solubilising 90% of the uranium of the ore.

Patent GB-887472-A (GB)
Title: Filter apparatus
IPC: B01D33/04
Filed: 1959-07-28
Abstract: 887,472. Travelling-band filters. HIRS, G. July 28, 1959 [Jan. 15, 1959], No. 25852/59. Class 46. Liquid, e.g. cutting oil from a machine tool, drains at 42 intc a tank 32, Fig. 2, and solids are deposited on a strip of filter medium 62 located between an endless conveyer 60 and the perforate top of an outlet chamber 44. Filtrate is withdrawn through an outlet 57 and pipe 59 and pumped (26) back to the machine tool. On attainment of a predetermined decrease in pressure in the outlet chamber 44 due to clogging of the filter medium 62, a bellows 128 closes a switch 126 to energize a motor 98 which drives the conveyer 60. The conveyer 60 consists of two laterallyspaced chains 64, Fig. 4, and transverse bars 66, and during the initial movement of it, it fails to take with it the filter medium 62 because of the high pressure differential across the perforate top 58 of the outlet chamber 44. Consecfuently the bars 66 scrape the filter medium until the pressure differential falls sufficiently for the conveyer to move the medium. At the end 40 of the tank the filter medium is trapped between the conveyer 60 and a second conveyer 100 driven by the first, both being supported by a perforate ramp 112. The filter medium 62 with solids thereon is discharged over the end 40. Some suspended solids are deposited directly by the liquid current on to the portion of filter medium located between the conveyers 60 and 100. In Fig. 14, an auxlilary outlet chamber 132 is provided next to the outlet chamber 44. A three-way valve 142 normally connects chamber 44 and outlet pipe 59 only but may be moved by an air cylinder 146 (operated by solenoid 148) so as to connect chamber 132 and pipe 59 only. An electric circuit is provided whereby upon switch 126 (see Fig. 2) being closed, valve 142 also is moved, in addition to motor 98 being started. Because the medium 62 above chamber 132 is not clogged, it is moved immediately upon movement of the conveyer 60. A timer and relay are also provided to maintain motor 98 and solenoid 148 energized for a specified time despite opening of switch 126 when pipe 59 and chamber 132 are connected.

Title: Safety device for manually controlled machines
IPC: B60K28/06
Filed: 1974-06-11
Abstract: 1472324 Safety device for manually operated machines O ISAKSSON 11 June 1974 [12 June 1973] 25861/74 Heading G1N A vehicle or machine having a manually operated control member includes a pair of parallel conductors arranged therealong which are arranged to be bridged by the operator's hands and are connected in a transistor switching circuit which changes state in dependence upon whether or not the control member is being gripped. A steering wheel of a car or boat, Figs. 2 and 3 (not shown) has two concentric copper wires arranged on or partly embedded in its front, rear or periphery which are connected to form a gap K in the circuit of Fig. 1. When the wheel is gripped so that the operator's resistance is introduced into the circuit transistor T1 conducts, T2 is non-conductive, T3 is conductive whereby relay S is energized to activate the car's ignition circuit. If the steering wheel is released or if the conductors are short circuited the transistors change state and the relay is de-energized to switch off the ignition circuit. A delay unit may be connected between the conductors and circuit to prevent operation due to momentarily release of the wheel. The conductors may be applied to the tiller of a boat or a press.

Title: Improvements in and relating to elastic fluid turbines
IPC: F01D17/26
Filed: 1926-10-16
Abstract: 259,991. British Thomson-Houston Co, Ltd., (Assignees of Dickinson, E. D., and Standerwick, R. G.). Oct. 16, 1925, [Convention date]. Fluid governors.-In a prime-mover wherein the same oil pump is used for the oil governor and for the lubricating system the adjustable bye-pass for the governor oil system and the pressure relief valve for the lubricating system are in manipulative combination. A turbine 1 drives an oil pump 26, the pressure in the delivery pipe 28, therefrom, varying as the turbine speed. The pipe 28 communicates with the underside of a governor piston 17, upward and downward movements of which operate the pilot valve 12 and servo-motor piston 7 to control the fluid supply to the turbine and thus decrease or increase the speed thereof. A bye-pass 29 from the pipe 28 leads to a valve-box 30 having compartments 36, 37, 38, Fig. 2, which intercommunicate by passages 39, 40 controlled by valves 41, 44 respectively. The valve 41 is fixed to the screwed rod 42; the valve 44 is slidable on the rod 42 and is loaded by a spring 47 which also bears on a nut 45 fixed on the rod 42. The oil in the chamber 37 is thus kept at constant pressure and is led by a pipe 48 to a valve-box 49 and pipes 50 to the turbine bearings. Excess of oil passes the valve 44 and is led from the chamber 38 by a discharge pipe 52 to the oil tank 53. Variation of turbine speed is obtained by moving the valve 41 to vary the oil pressure in the chamber 36. The pressure in the chamber 37, however, always remains constant, due to the nut 45 moving with the rod 42 to allow for the variation in the amount of oil passing the valve 44.

Title: Improvements relating to the preparation of liquorice paste and similar paste or gelatinous products for confectionery and other purposes
IPC: A23G3/02
Filed: 1959-11-12
Abstract: 883,440. Confectionery. KNOCH, H. Nov. 12, 1959, No. 25914/58. Class 28 (1). The ingredients for liquorice or similar paste to be extruded or moulded, are first partially cooked in a mixing-kettle 10 with only sufficient water to later gelatinize the complete starch content by heating high enough to dissolve the sugar and turn the flour into a slurry but below starch gelatinization. The mixture is then cooked above starch gelatinization temperature, e.g. in a plate or other heater 14, such higher heating bursting the starch granules to form a suspension in the mixture. The mixture is then sprayed by a perforated tube 15 into atmosphere or into a vacuum hood 17 which extracts surplus moisture, the mixture falling into a receiving bin 20. Alternatively, surplus moisture may be removed in a drum or cylinder drier, or the water may be extracted by allowing the steam to escape from the second heating. The second heating may be done by a steam injector which also pumps the material along to the water extraction stage.

Abstract: 616,238. Aircraft emergency escape apparatus. MARTIN, J., and MARTIN-BAKER AIRCRAFT CO., Ltd. Aug. 31, 1946, No. 26265. [Class 4] A drogue parachute 7 is attached to a seat 1, of the type that may be ejected from an aircraft in an emergency by an explosive cartridge acting in a cyclinder attached thereto, the object being to steady the seat in the air after its ejection. The drogue parachute 7, attached to the seat by nylon cable 8, is normally stowed folded in a compartment 6. A piston 12, secured to the top of the drogue parachute 7 by cable 13, rests in the barrel 14, screwed into the socket end 16 of a bracket 15 forming the breach end of an ejector gun fixed to the seat back 5. A cable 27, secured at its lower end to a fixed part of the aircraft, passes through a cylindrical guide 28 and has a ferrule 29 at its top end resting in a slot 31 at the end of one arm of the bell crank 25-26. When the seat 1 is ejected from the aircraft, the pull on the cable 27 rotates the bell-crank 25-26 before releasing itself therefrom. Rotation of the bell-crank 25-26 by displacement of the wedge-shaped sear 24, first cocks and then fires the spring-loaded firing pin 20. Detonation of a cartridge 21, located in the end socket 16 of the ejector gun drives out the piston 12, breaking through a pin 44 holding it in the barrel 14 and thereby draws out the drogue parachute 7. In a modification, the drogue parachute may draw out a main parachute attached either to the chair itself or the occupant thereof. Specification 583,257 is referred to.
