Title: Improvements in or relating to washing machines
Inventor: DOW ALEXANDER BRIAN RODERICK
IPC: D06F23/00
Filed: 1959-06-26
Abstract: 964,506. Washing machines. RADIATION Ltd. Aug. 17, 1960 [June 26, 1959], No. 22036/59. Heading D1A. In a washing machine having a rotatable tub 2 and agitator 4, in which the agitating mechanism is mounted integrally with the tub 2 and rotatable therewith, a brake is provided which is held by gravity in the "on" position during agitation and is automatically operated to the "off" position to permit rotation of the tub. The brake comprises a conical element 26 secured to the machine base and adapted to co-operate with a conical portion 32 of a plate 25 secured to a drive tube 16 carrying the spin assembly. During washing the brake is on, and drive from a motor M is transmitted through a pulley 33 on a drive shaft 34 to reduction gearing and crank mechanism in a housing 15 for oscillating the agitator. A driving helix 37 (Fig. 5) keyed to the shaft 34 co-operates with a driven helix 38 freely mounted on the shaft 34. The driven helix 38 is rigid with a clutch plate 39. For spin drying, the motor M is reversed so that the driving helix 37 causes the driven helix to raise the clutch plate 39 into engagement with the clutch face of the drive plate 25 and also to lift the spin assembly so that the brake 26, 32 is off. Relative movement between the helix elements 37 and 38 is limited to 180 degrees after which the drive is positive to the clutch plate 39. A spring 41 interconnecting the elements 37, 38 reverses this rotation at the end of the spin period thereby disengaging the clutch plate 39 from the drive plate 25. The shaft 34 extends into a bearing 30 in a rubber bush 31 which permits gyration of the spin assembly. Water discharge. A V-belt (Fig. 4) connecting the motor and drive pulleys 50, 33 respectively can be brought into driving engagement with a discharge pump wheel 54 by means of a jockey wheel 51 mounted on an arm 52 having a pin and slot mounting 53. A cable 56 moves the belt away from the wheel 54 against the action of a spring 55.

Abstract: 626,296. Manure distributers. YADOFF, O. Aug. 30, 1945, No. 22376. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 31, 1946]. [Class 6(i)] [Also in Groups VI and XXIX] An apparatus for distributing powder comprises means for entraining the powder in an air-blast travelling at supersonic velocity, the powder grains becoming spontaneously charged thereby. The distributer comprises a cylindrical reservoir 1 provided with a venturi nozzle 2 at one end. Air is supplied from a compressor 10. A tube 3, communicating with a powder container 4, passes axially through the reservoir and terminates near the nozzle 2. The axial tube, the nozzle, and the inlet tube from the compressor are all provided with stopcocks 5, 7 and 9. In operation, the compressor pumps air into the reservoir until a suitable pressure, as recorded by a gauge 13, is attained. The other stopcocks are then opened and a high-velocity air blast issues from the nozzle. Powder grains entrained in the blast automatically become electrically charged by friction, but an electrode (not shown) may be located in the nozzle to assist this action. The apparatus is mounted on a wheeled chassis 11.

Title: Improvements in or relating to compositions comprising urea-formaldehyde condensation
IPC: C08L61/34
Filed: 1965-05-26
Abstract: A synthetic resin composition comprises an aq. soln. of a furfuryl alcohol modified ureaformaldehyde condensate, an acidic curing catalyst in an amount to produce a pH below 7 and a nitrite in combination with either tetra-hydro - 1 - hydroxy - oxazolo - 3,4 - methylene-oxazole - 7 - a  - methanol (oxazole) or hexa-methylenetetramine (hexa).  The nitrite is preferably water soluble and may be an alkali metal nitrite in amounts of 0.2 to 4.5 parts per 100 parts of condensate.  The " hexa " may be used at 0.08 to 1.3 parts per 100 parts of condensate. Additional urea may be incorporated in the solution at between 5 and 15 parts by wt. of condensate.  Shaped bodies (e.g. foundry moulds and cores) may be made by mixing the resin composition with sand, shaping the mixture and heating it (e.g. to 350-500 DEG  F.) to initiate curing of the condensate.  The shaped mixture may be removed from the mould after it has been partially cured and final curing obtained as a result of the exothermic curing reaction.  Examples relate to the use of sodium and potassium nitrite, potassium cobaltinitrite and butyl nitrite.
