Title: An improved clothes-washing machine
IPC: D06F21/08
Filed: 1951-04-28
Abstract: 696,533. Washing and drying machines. NAAMLOOZE VENNOOTSCHAP APPLETON PTY., Ltd. April 28, 1951. [Jan. 5, 1951; March 29, 1951; Oct. 3, 1951] No. 30318/51. Class 138 (ii). A washing machine includes a drum 15 having a substantially vertical axis, means for rotating the drum to cause continuous rotary flow of liquid and clothes in the drum about its axis, interrupter means associated with the drum, locking means for releasably holding the interrupter means stationary in the drum to oppose such flow and cause agitation of the liquid and clothes, and means for withdrawing liquid from the drum after releasing the locking means to bring the interrupter means out of such opposition so that the rotary flow is unimpeded thereby. In Fig. 1 a plain or ribbed rotatable roller 44 is removably mounted near the side wall of the drum 15 which is rotated by means of a motor 21 whose shaft carries a friction wheel 23 which engages a cylindrical flange 19 on the drum. The roller 44 is rotatable on a spindle 45 carried by a plate 46 having a handle 49 and an upwardly extending metal rod 47, the upper end of which is bent at right angles and engages in a socket 50. The rod 47 is engaged by a projection 51 which is L-shaped in plan. An extraction chamber 32 is formed by two flanged rings 25, 26 secured to the mouth of the drum and an annular recess 24 in the drum itself. An outlet pipe 41 has an obliquely cut opening 42 and is slidable in a support 37 from the washing position shown in Fig. 1 to the drying position in which the mouth of the pipe 41 lies close to the wall of the recess 24. For removing water from the clothes, the roller 44 is removed and the rotation of the drum causes the water to rise up the sloping wall of the drum and into the extraction chamber through perforations in the ring 26. A flange 30 on the ring 26 prevents residual water in the recess 24 from flowing back into the drum as the drum slows down. The opening 42 in the pipe 41 acts as a scoop, an anti-splash plate 36 being provided in the vicinity of the pipe 41. The drum 15 has a base 18 and a false bottom 16 secured to a shaft 14 rotatably mounted in bearings 13 in a cylindrical member 12 which is supported by four arms 11 secured to a square base member 10. The false bottom 16 has a least one substantially radial vane 17. Water is supplied to the drum through an inlet pipe 38. In another embodiment (Fig. 5) two rollers 82 are rotatably mounted on arms 79 which extend from a boss 78 rotatably mounted on a drum shaft 14. During washing, the arms 79 are held stationary by a brake arm 90 pivoted on lugs 89 and operated by means of an eccentric device 92 and handle 93. For drying, the rollers 82 rotate with the drum, the water being expelled through openings 76 in the drum and passing through an outlet 63 to waste. Water is supplied to the drum through a pipe 94.

Title: Improvements in coin freed lock or latch mechanism
IPC: G07F17/14
Filed: 1931-11-03
Abstract: 380,286. Coin-freed locks. PARKER, WINDER, & ACHURCH, Ltd. and BATES, W. E., Broad Street, Birmingham. Nov. 3, 1931, No. 30387. [Class 27.] Coin-slit closing- devices; indicators.- In a coin-freed lock having means for closing the coin-slit automatically after the insertion of a coin to prevent the insertion of further coins until the means are released, the passage of the coin into the lock effects automatically in succession the movement of an indicator plate and the closing of the coin-slit. A coin inserted in a slit 38 engages projections 47, 53 on a slot-closing plate 46 and a lever 50 respectively and rocks the plate 46 and lever 50 apart about their pivots 48, 51. The lever 50 is weighted and by means of a pin 52 engaging a slot 45 raises an indicator plate 40 to show "engaged," the indicator being retained in this position by the end of a pawl lever 54 engaging the lever 50 below a shoulder 56 thereon. After the passage of the coin, the plate 46 falls until its projection 47 engages a notch on the top of a plate 49, to which the plate 46, and lever 50 are pivoted, thereby preventing the insertion of further coins. When the indicator plate shows "vacant," the lever 50 supports the plate 46 out of engagement with notch, as shown in Fig. 3, so that it can be moved aside by pushing in a coin. The pawl 54 is rocked to return the indicator to "vacant" by turning the inside handle 12, Fig. 6, which operates a follower 57 engaging projections 28 on the latch plate 14, the follower 57 also releasing the lock pawl 54. Fastenings for doors ; coin action, mechanicalconnection.-The latch 14 with bolt 15 is withdrawn after the insertion of a coin by a latchactuating plate 19 operated by the outside handle 11. The plate 19 is actuated by an arm 17 on the spindle of the outside handle and the coin forms a coupling between ribs 22, 23 on the plate 19 and latch 14 respectively. The door can be opened by a master key inserted through a key-hole 64 and rocking a lever which engages a projection 29 on the latch 14. If an auxiliary bolt 68 is provided on the inside of the door, this has a pin 69 engaging a slot 31 in the latch so that it is withdrawn with the latch 14, when this is operated.

Title: Method of and apparatus for prestressing glass articles
Inventor: GABOR DENNIS
IPC: C03B27/06
Filed: 1956-10-05
Abstract: 846,467. Prestressing glass articles. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 4, 1957 [Oct. 5, 1956], No. 30405/56. Class 56. A method of prestressing a glass article comprises heating the article to a temperature above the transformation temperature of the glass, cooling the marginal regions slowly through the transformation temperature and thereafter cooling the whole article rapidly whereby the central region passes rapidly through the transformation temperature to give a central tempered region surrounded by an untempered or only partially tempered marginal region. The cathode ray tube cap 1, as turned out straight from the moulding process, is placed on a matching ring 2 of ceramic material having a number of large holes and resting on a plate 3. This assembly is rested on chains 10 running in channels 11 which carry the assembly through an annealing tunnel. At the point where the chilling stresses have been eliminated and the glass is at its maximum temperature, a trolley 12 is passed across the chains 10, replacing the channels 11, and a pair of asbestos plate 13, 131 are pivoted around their axes 14, 141 to be close to the centre portion of the cap 1, covering roughly the area shown shaded in Fig. 9a, the trolley 12 continuing with the assembly through the tunnel while the marginal areas and rim cool slowly to approximately the transformation temperature. The plates 13, 131 may be curved so as to be close to the cap 1 and are pre-heated to a somewhat higher temperature than the glass. At the end of the tunnel, the rim having cooled through about 50‹C., the plates 13, 131 are swung out of position and baffles 4, 41 swung into position and the cap 1 quenched either by compressed air or air reinforced by water. The baffles 4, 41 are mounted on sleeves 16, 161 pivoting around hollow shafts 17, 171 which serve as pipes for supplying compressed air from a flexible hose 18 to manifolds 15, 15<SP>1</SP>, the sleeves 16, 161 also serving as valves. The baffles 4, 41 have air ducts 5, 5<SP>1</SP> connected to the manifolds 15, 15<SP>1</SP>, with small holes 6. The air escapes as shown in Fig. 7, through outlet holes 7, 71, the holes in the ring 2 and under the top baffle 4. Preferably for rectangular caps, the air blast holes 6 are set wider apart at the corners and closer together near the middle of the sides, as shown in Fig. 9a. Specification 739,496 is referred to.

Title: Fuel supply system for internal combustion engines
IPC: F02M51/02
Filed: 1957-09-27
Abstract: 858,964. Fuel control systems. BENDIX CORPORATION, [formerly BENDIX AVIATION CORPORATION]. Sept. 27, 1957 [Nov. 16, 1956], No. 30406/57. Class 40 (1). [Also in Group XXVII] In a fuel injection system having electromagnetically operated fuel injectors, the duration of injection is temporarily increased during acceleration by the adjustment of means in the electrical circuit. The energization circuit of the valve solenoids 132, Fig. 3, includes a pulse producing mechanism comprising a switch 84, operated by an engine-driven shaft, which triggers a multivibrator 94, the time duration of the pulses produced by which are controlled by potentiometers adjusted in response to engine operating conditions. The pulses are amplified by an amplifier 98, the output of which is connected to a ring 124 in a distributer 26 comprising an arm 128, on an engine driven shaft 86, which connects the ring to a succession of contacts 130 connected to the valve solenoids 132. During normal running the time constant of the multivibrator 94 is controlled by a first circuit comprising potentiometers 100, 102, 104, 106 and 108 varied respectively by devices responsive to altitude, manual operation, induction pipe pressure, ambient air temperature and engine temperature; during low air flow conditions a switch 120 operated by the throttle shaft closes an alternative circuit including potentiometers 100, 102, 106, 108 and 118, which latter is manually adjusted. The accelerator device comprises a spring-loaded diaphragm 64, Fig. 2, which is connected to the intake pipe by connection 78 and normally holds contacts 72, 74 closed to form a shunt around a resistance 110 in the first circuit. During acceleration the increased pressure in the intake pipe temporarily raises diaphragm 64 to break contacts 72, 74, whereby resistance 110 is placed in series in the first circuit and causes a temporary increase in duration of injection. An orifice 70 in diaphragm 64 permits gradual equalization of the pressure on opposite sides of the diaphragm and allows the contacts 72, 74 to reclose. In a modification, Fig. 4, the increase in pressure on the lower side of diaphragm 164 is produced on acceleration by a piston 182 actuated from the throttle valve mechanism. Specifications 858,961 and 858,965 are referred to.

Title: Improvements in and relating to apparatus for use in cutting, shaping, profiling and the like processes
IPC: B23B5/42
Filed: 1919-12-05
Abstract: 160,227. Wildey, E. M. Dec 5, 1919. Backing-off lathes; attachments for turning.-Apparatus for relieving, profiling, &c, of the type having a pivotallymounted tool-holder comprises means for imparting an adjustable oscillatory movement to the tool-holder and is adapted for peripheral side or spiral relieving. The tool is carried in a holder 5 pivoted on a shaft 4 supported by cups 8 in a bracket 2 adjustable along a base plate 1 which may be fixed to the lathe saddle. The holder is acuated by means of a link 11., the upper end of which is mounted on a bolt 13 adjustable in a slotted arm 14 on a shaft 15 carried in the upper part of the bracket. A sleeve 22 driven at the same speed as the lathe spindle is slidably keyed to a shaft 21 universally mounted in a hollow shaft 16 carrying a cam-wheel 36 having teeth corresponding in numbers to those on the work. The camwheel is engaged by a finger 35 to rock a bellcrank mechanism 34, 29 carried on a stud 31 and connected by links 25, 23 to the shaft 15. The rotation of the cam-wheel thus produces an oscillatery movement of the tool holders, a quick withdrawal of the tool being effected by springs 38, 39. By adjusting the pivot of the link 25 on a scale on the arm 29, the amount of relief imparted to the work may be varied. A compensating- scale fixed on the arm 14 may be adjusted so that the same setting of the link 25 gives the same relieving movement whatever the number of teeth on the cam-wheel 36. For side-relieving. the boss of the arm 23 has teeth 44 engaging teeth on a boss 47 carrying an arm engaging an adjustable block mounted in a recess in the tool-holder as shown in Fig. 7. One of the cups 8 M stacked off to allow the required longitudinal movement and the return is assisted by adjustable springs 55. Thus both side and peripheral relieving may be effected at one operation or either or, for ordinary turning, both motions may be made inoperative. For spiral relieving, the driving-sleeve is connected to the shaft 21 through a spiral key of the same angle as that required in the work.

Title: Methods of treating raw magnesite to reduce its quartz content
IPC: C04B2/10
Filed: 1954-10-25
Abstract: <PICT:0757286/III/1> <PICT:0757286/III/2> Raw magnesite, e.g. for use in the production of magnesite bricks, is treated to remove excess quartz from it by exposing the pieces to heat sufficient to raise the temperatures of individual pieces very rapidly to more than 575 DEG C. and cause the quartz grains to burst, thus causing physical disruption of the individual pieces of the magnesite and separating the quartz dust thus produced from the disrupted magnesite.  The magnesite may be heated by feeding it into an externally heated furnace chamber and/or by the passage of hot gas in contact with the magnesite. The process may be carried out in a rotary furnace 3, Fig. 1, which is heated to a temperature of about 700 DEG C. at the inlet end by a stream of hot gases produced by the combustion of gas from a pipe 4 with primary air from a pipe 6.  The lumps of magnesite, introduced through shoot 2, break up and the quartz component is carried by the hot gas stream into a collecting chamber 8.  The magnesite passes along the rotary furnace and is thereby sintered and is discharged from the furnace via cooling drum 13.  The air passing into the cooling drum is used as primary air for the furnace and additional primary air is preheated by a recuperator 9 in the furnace gas discharge.  The raw magnesite may also be heated by introducing it into the tops of vertical furnace chamber 16, Fig. 2, heated to a temperature of 700 DEG C. by an external flue 20; the broken magnesite and quartz dust fall on to the top of the charge already in the furnace and, as the charge sinks, is discharged from the furnace via discharge feeders 22 after which the magnesite and quartz dust are separated.
