A device for testing the hardness of magnetizable metals comprises a magnet, for attachment to the test specimen S<SP>2</SP>, in which is held an adjusting element 25a connected by a spring element 29a to a penetrator 19a. The load applied is indicated by a gauge 38a actuated through flexure of the spring element, and the depth of penetration indicated by means 42a, 46a operated through movement of the element 25a. As shown, a permanent horseshoe magnet 10a, bifurcated at 60 so as to have three-point contact with the specimen S<SP>2</SP>, has a central bore in which is secured a non-magnetic tube 62. The element 25a is screw-threaded in the tube and carries a hand wheel 28a with a sleeve extension 67 on which is adjustably held by a spring-urged ball 68 the graduated indication collar 42a which co-acts with a mark 46a on a fixed transparent member 41a. In operation, the wheel 28a is rotated to bring the penetrator 19a into contact with the specimen until the gauge pointer registers " Set." The collar 42a is rotated to the zero position and the wheel is further rotated until the indicated load is 15, 30 or 45 Kg. The wheel is then turned back until the gauge pointer again registers " Set," when the collar 42a will indicate the penetration depth. After the test, the magnet 10a may be forced away from the specimen by screws such as 78 engaged in non-magnetic straps 75 secured to the inner surface of the magnet. Alternatively, an electromagnet may be used, the screws and straps then being unnecessary.
Patent GB-499946-A (GB)
Title: Improvements in and relating to ironing machines
IPC: D06F67/10
Filed: 1938-08-09
Abstract: 499,946. Ironing-machines. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 9, 1938, No. 23477. Convention date, Aug. 11, 1937. [Class 138 (ii)] In an ironing-machine wherein the ironing is effected by the rotation of a roller 27 in contact with a concave shoe 79 the roller may be held stationary in contact with the shoe whereby the machine may function as a press. The roller is provided with an internal sleeve 34 freely surrounding an eccentric 36 journalled on a stationary tube 19 coaxial with the roller and secured at one end in the gear-housing (not shown). The eccentric is secured to a shaft 18 extending through the tube 19 and having a constantly rotating worm wheel 17 and integral pinion 21 loosely mounted thereon. When the worm wheel is clutched to the shaft, by the actuation of a lever 69 by the knee of the operator, the shaft is rotated to raise the roller into operative engagement with the shoe and the clutch is thrown out automatically after the shaft has rotated through 180‹. An internally-toothed wheel 39 within the roller has now engaged the pinion 40 driven by the constantly moving pinion 21 so that the roller rotates in contact with the shoe until the shaft 18 is again clutched to the worm wheel, when the roller is moved out of contact with the shoe and the drive is broken. The roller may be held stationary in contact with the shoe by the manual actuation of a lever 52 which rotates a shaft 50 and through a stop arm 49, raises the shaft 41 thereby disconnecting the pinion 40 from the internal gear wheel 39. The shaft 41 is connected through a flexible coupling 44 to the shaft 25 carrying the pinion 24 driven by the pinion 21. Rotation of the roller during its movement into contact with the shoe is prevented by providing an intermediate sleeve 35 between the eccentric 36 and sleeve 34 with a tongue 77 which engages a radial slot 78 in a disc 43 secured to the tube 19. The end of the shaft 41 adjacent the pinion 40 travels in a slot 42 in the disc 43.

Money-delivering apparatus.-A change-giving device comprises a number of similar separately operated sections 1 - - 5 adapted to deal with coins of different sizes and which can be united by means of small bolts to form a curved bank of sections. Each section comprises a coin-tube 32, stationary plates 11, 14 between which lie slides 16, 27, 28, 29 and a slidable ejecting-plate 18, and mechanism to operate the slides. The ejecting-plate 18 lies directly above the plate 11 and any desired number of the superimposed slides 27, 28, 29, 16 are attached to it by a screw 25 the remaining slides being fixed by a screw 17 to the plate 14. Each slide, which is of the same thickness as the coin to be ejected, has a circular coin aperture, the stationary plate 11 having a semi-circular recess normally out of register with the coin apertures in the slides. For the introduction of coins, the tube 32 has a slot in the cap. The ejecting mechanism comprises shafts 40, 45 secured to the frame. The shaft 40 has depending levers 41 which pass through slots in the plates 11, 14, 16, 27, 28, 29 and fit in a notch in the plate 18. Pivoted levers 46 on the shaft 45 each have an upwardly extending crank-arm 47 on which is formed a pin 48 engaging a slot 49 in the respective lever 41. Two springs are coiled round a spacing-sleeve on the shaft 45, one end of each spring being bent round a pin 48, the other end pressing on the plate 14. The levers 46 are joined by a crosspiece 52 which extends in front of the coin-tube 32 and serves to actuate the mechanism. To lock the ejecting mechanism, a bar 21, slidably attached beneath the plate 11 and formed with a lug 23 ordinarily projecting into a slot in the plate 18, is moved laterally and engages a notch in the plate 18 preventing its movement. The ends of the locking bars contact when the sections are assembled together and the movement of one locking-bar actuates the others.

Title: Improvements relating to means for regulating the supply of fuel to internal combustion engines
IPC: F02D9/02
Filed: 1952-09-19
Abstract: 714,662. Retractive switches. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Sept. 19, 1952 [Sept. 20, 1951], No. 23596/52. Class 38(5) [Also in Group XXVII] An electrically actuated valve regulating the fuel flow to a carburetter nozzle is controlled by a switch A, Fig. 4, actuated by the throttle valve operating mechanism. The switch A forms a resilient connection in the operating linkage 10, 11, of the throttle valve 2 the spindle 3 of which carries a pulley co-operating with a tensioned cord to form a friction brake which holds the throttle valve in any set position. The accelerator pedal 8 is connected to the rod 10 which carries a member 15 slidable between stops 19, 20 in a casing 16 attached to the throttle valve operating rod 11. The member 15 carries a contact strip 21, co-operating with contacts 23, 24 and connected by a lead 22 to a dynamo, and is resiliently connected to the casing 16 through a plate 18 and spring 17. In the part-open throttle position shown in Fig. 4 the strip 21 is adjacent the contact 24 leading to a centre tapping of the valve actuating solenoid whereby part of the solenoid is energized to move the fuel valve to a partly closed position. If the accelerator pedal is depressed, the member 15 first moves to the right to take up the lost motion between the parts 15, 16, whereby the solenoid circuit is broken and the fuel valve is fully opened prior to the opening of the throttle valve which occurs when the member 15 contacts the stop 20 and transmits the movement of the pedal 8 to the casing 16 and rod 11. In this position the strip 21 may be arranged to engage a contact 25 to energize a solenoid which adjusts a distributer 48 to retard the ignition. When the pedal 8 is released the member 15 moves with lost motion to the left until the projection 10a contacts the plate 18 in which position the strip 21 again engages the contact 24 to energize part of the fuel valve solenoid and move the valve 31 to reduce the fuel supply. Subsequent movement of the pedal 8 and member 15 is transmitted to the casing 16 and rod 11 through the spring 17 to close the throttle valve, the spring 17 being powerful enough to overcome the friction brake on the throttle valve. When the throttle valve 2 is completely closed, further movement of the pedal 8 to its rest position causes compression of the spring 17 and additional lost motion of the member 15 until the strip 21 engages the contact 23 which puts the whole of the fuel valve solenoid in circuit with the dynamo 46. If the engine speed then rises above idling speed the fuel valve completely shuts off the fuel.

Abstract: 342,646. Gas producers. WHITFIELD, C., 2, Layer Gardens, Acton, London. Aug. 3, 1929, Nos. 23861/29 and 27/30. [Class 51 (i).] In a gas producer the air for combustion is supplied to separate sections of the grate through separate distribution chambers, the entrance to each chamber being restricted so that the air reaching each section of the combustion surface of the grate is restricted in volume to a predetermined amount required to produce its proportion of carbon monoxide from the carbon of the fuel. As shown in Figs. 1, 4 and 6, the grate is formed by longitudinal firebars b of girder section the lower flanges d being adapted to meet, forming open-ended longitudinal air chambers. The upper flanges e of the bars are narrower than the lower flanges d and have notches f extending into the web, the width of the notches being determined by the requirements of the grate and the fuel to be used. Shutter flaps are provided at each end of the chambers, one entirely closing one end and the other g being shorter and leaving an air opening below. In a modification, Figs. 9 and 10, the longitudinal air chambers are subdivided and separate restricted admission of air to each subchamber is provided. This is effected by the provision of a central bar k in the longitudinal chamber on which are secured angle-pieces m arranged in pairs at uniform distances along the bar and forming a dividing member extending across the longitudinal chamber and normally registering with ribs b<1> on the sides of the fire bars. Combustion air is admitted through longitudinal slots o arranged centrally in the bottom of the subchambers. These slots are of less area than the grate apertures of the corresponding section but are wide enough to permit the discharge of ash or the like, said discharge being effected by a longitudinal movement of the bar k. The bottom of the air chambers may be formed either by flanges on the firebars or by plates n secured to the bars by screws n<1>. A grate of not less than four sections, a section being not larger than half a square foot, is preferred. According to the Provisional Specification the grate may be adapted to reciprocate, oscillate or rotate.
