Title: Improvements in or relating to washing machines
IPC: D06F34/08
Filed: 1962-07-10
Abstract: 1,005,836. Washing machines. ROBERT BOSCH G.m.b.H. July 10, 1962 [July 11, 1961], No. 26372/62. Heading D1A. [Also in Division H2] A washing machine, in which at least a soaking and a washing stage are controlled automatically, has an adjustable time switch by which the length of the soaking stage during which the laundry is not agitated may be adjusted independently of the rest of the programme, the soaking water being discharged prior to the washing stage. In Fig. 3, a gear 84, and a cam 88 which operates contacts 90, are mounted on a shaft 86, the rotation of which is terminated when a stop 104 on the gear 84 meets a stop 106 at which position the contacts 90 are closed. To set the duration of the soaking stage, the shaft 86 is rotated from this position manually with a handle, thereby opening the contacts 90. The gear 84 is driven to rotate it back, through gearing and a friction drive 98, 100, 102 from a shaft 52 itself driven through gearing 50 by a synchronous motor 12 when the latter is energized by (adjustable) cams of the main cam-shaft (not shown in Fig. 3) of the programme controller. The shaft 52 also mounts cams 54, 56 to control reversing contacts for the motor driving the washing container. The energization of a motor driving the main cam-shaft is ensured by the latter at the beginning of the cycle when soaking liquid (water plus a soaking agent) is being admitted and when the container is being rotated to thoroughly wet the laundry, but after these operations the camshaft motor and the washing motor are stopped, neither to be re-energized until near the end of the soaking stage when the cam-shaft motor is reenergized through the contacts 90. The container is rotated for two minutes before emptying. The heating is off during soaking which may last up to twelve hours. In a modification, processes during the soaking stage may be controlled by the unit shown (modified) thereby simplifying the main cam-shaft. In addition, the driving connections between the motor 12 and the reversing switches and the time switch (cam 88 &c.) may be made disconnectable by clutches controlled by the time switch so that the reversing switches and time switch are not operated when the washing motor is stationary during soaking, and thereafter, respectively.

Abstract: 1,242,783. Epoxyresin coating. GENERAL MILLS Inc. 23 May, 1969 [27 May, 1968], No. 26547/69. Heading B2E. [Also in Division C3] Substrates of steel, aluminium, glass, galvanized iron and masonry are coated with a composition comprising an aqueous emulsion of an epoxy resin cured by an adduct of a C 2-12  aliphatic monoepoxide or an aromatic substituted aliphatic monoepoxide with an aminoamide obtained by reacting a fat acid with an alkylene polyamine. Preferred aminoamides (which may be added as solutions in inert-solvents) are prepared by reacting a polymeric fatty acid (especially from tall oil fatty acids) with H 2 NR'N(R")(R'NH) n H in which R' is a C 2-6  alkylene radical, R" is H or R'NH 2  and n is 0 to 3, e.g. triethylenetetramine. The monoepoxide may be styrene oxide, phenyl glycidyl ether or cresyl glycidyl ether and may be reacted with the aminoamide at 85-150‹C so that one epoxide equivalent is present per primary amine group equivalent of the aminoamide. The compositions may contain some free polymeric fatty acid and pigments. The compositions may be supplied as a two part pack one part comprising the epoxy resin emulsion and the other the aminoamide-monoepoxide adduct. When mixed they have a pot life of 4-5 hours at 23‹C.

Title: Improvements in methods of producing composite bodies from thermoplast-bonded stranded materials
IPC: B32B27/00
Filed: 1960-08-05
Abstract: A method of producing a composite body comprising thermoplast-bonded stranded material comprises coating continuous length fibres, e.g. rayon or glass fibres, with the thermoplast whilst it is in the fluid or dispersed state, gathering the fibres into a continuous strand before the thermoplast has set, and subsequently bonding a further quantity of the same thermoplast to the stranded material to form the body.  The stranded material may be woven into a mesh or formed into a mat prior to the bonding step, and the bonded mesh may be shaped by a compression or injection moulding process at a temperature above the melting point of the thermoplast.  Thermoplasts mentioned are polyamides, saturated polyesters and olefinic polymers.  The fibres may be coated by molten thermoplast, by gaseous or liquid dispersions or solutions of the thermoplast, or by a fluidised bed method in which the fibres are heated prior to coating to a temperature 100 DEG to 200 DEG C. higher than the melting point of the thermoplast.

Abstract: 1,070,028. Grinding. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. July 2, 1964, No. 27389/64. Heading B3D. A method of producing rotationally symmetrical aspherical surfaces comprises rotating a workpiece 1 about an axis 2 and machining the workpiece by means of a circular or annular tool 3 which rotates about an axis 4 and is moved so that its centre 7 travels along a circular or other twodimensionally curved guide path 9, the point of contact between the tool and workpiece describing a curve which does not lie in the plane 8 containing the guide path. The axis of the tool may form a fixed or variable angle α with the plane 8, and the line joining the points of intersection of the working line of the tool with the plane may also form a fixed or variable angle with a line joining the centre 7 with the centre 6 of the guide path. The centre 6 of the guide path may lie on the stationary axis 2 of the workpiece and inside or outside the circular tool. The shape of the aspherical surface, which may be a reflecting or refracting surface of an optical component, is determined also by the distance between the points 6, 7, the diameter of the tool and the angle α which may vary from 0‹. The plane 8 may be parallel or inclined to the axis 2 of rotation of the workpiece.

[Also in Group XXXVII] A textile ring spinning machine is associated with a frequency changer 24 which is driven through belt gearing 25 by a main motor 23, and is excited through contactor 21. Spindle motors 14 are supplied from the frequency changer which also provides a supply for a motor 29 which drives delivery rollers 10 through gear train 30 and also the building motion by which the traverse of ring rail 11 is effected. The speeds of the motors 14, 29 are regulated by adjusting the output of the exciter, independent starting and stopping of the spindle motors being afforded by separate switches 15. A solenoid-operated brake on the shaft of the motor 29 ensures the arrest of yarn delivery simultaneously with the collective stoppage of the spindles. Separate reversing switches for the spindles on two sides of the machine allows independent twisting in either direction. The motor 23 is associated with an isolator 19 and starter 20, the motor 29 having an overload release 31. A capacitor 32 provides power-factor correction for the machine.
