Patent GB-637503-A (GB)
Title: Improvements in and relating to washing machines
IPC: D06F37/36
Filed: 1945-08-23
Abstract: 637,503. Washing - machines. BRITISH THOMSON - HOUSTON CO., Ltd. Aug. 23, 1945, No. 21557. Convention date, Aug. 25, 1944. [Class 138 (ii)] A washing-machine includes (a) a hydraulic motor comprising a vane arranged to oscillate in a cylindrical casing, the vane being operatively connected to washing means such as an agitator and the casing being connected to the tube for centrifugal extraction, (b) a drive-shaft rotated by an electric motor and connectable to the cylindrical casing through a hydraulic coupling, and (c) pumping means driven by the drive shaft to supply hydraulic fluid to the hydraulic motor for washing and to the coupling for extraction. As shown in Fig. 1, the machine comprises a casing 1 and a tub 2, the latter being mounted on legs 4 secured to a hub 7 fixedly connected by a clamp 8 to a shaft 9. An agitator 11 within the tub is secured to a shaft 13 oscillatable within the shaft 9, both shafts being controlled by mechanism in a casing 22. An electric motor 31, Fig. 2, has connected to the upper end of its shaft 33 a vane-type oil pump capable of lifting oil from a sump in the bottom of the casing via a solenoid-controlled valve 47. When the solenoid is energized, a plunger 46 uncovers a port 45 to allow the oil to reach the pump, the discharge from which causes the oscillation of a vane 67, Fig. 4, connected to the agitator shaft 13. Oscillation of the vane is controlled by a valve member 57 rotated by gearing from the motor shaft, a port 72 in the valve allowing oil from the pump to pass alternately to either side of the piston via passages 68, 69 and oil being forced from the reverse side of the piston to exhaust through ports 74, 70. The shaft 9 for rotating the tub is secured to the motor cylinder 34, which is in turn secured to a cone brake 80 and to one half of a hydraulic-coupling 84. During oscillation of the agitator the brake cone is urged by a spring 81 into engagement with a fixed surface 82, thus preventing rotation of the tub. A second vane oil-pump located at the lower end of the drive shaft 33 is brought into operation when the valve 47 is de-energized and a second valve 92 is energized. Fluid from this pump flows to a bellows 90, which on expansion releases the brake 80. Fluid from the pump also enters the coupling 84, 85 to establish a drive between the electric motor and motor casing 34 to rotate the tub.

Title: Improvements in or relating to the production of compositions containing rubber and the like suitable for use as adhesives
IPC: C08C19/00
Filed: 1937-08-06
Abstract: Adhesive compositions are made by heating a mixture of rubber, guttapercha or the like and a polymerization product of a halogen-substituted butadiene, e.g. neoprene, with a condensing agent.  Suitable condensing agents specified are compounds having the characteristic group SO2OH, or capable of forming a compound containing this group, e.g. sulphuric acid, sulphonic acids, stannic chloride and phosphoric acid.  The rubber and substituted butadiene polymer may be mixed and treated dry, in solution, or in aqueous dispersion.  Resins from rubber, guttapercha or balata may be added. In an example 100 parts by weight of rubber and 50 parts of polymerized chloro-butadiene are mixed on a roller mill and a mixture of 2 parts of phenol and 2 parts of sulphuric acid is milled in.  The mixture is heated at 110 DEG  C. for about 20 hours.  The black, porous mass which results is milled for 30 mins. and dissolved in benzene to form a cement for adhering rubber to metal.  In another example 6 parts of rubber, 3 parts of polymerized chlorobutadiene and 30 parts of balata resin are mixed with 1 part of phenol and 1 part of sulphuric acid.  The mixture is heated at 110 DEG  C. for about 4 days.  The product is hard and resinous when cold and tough and elastic when hot.  Other examples are given.  Specifications 247,136, 249,172, [both in Class 70], 343,531, 395,430, and 412,634 are referred to.

Title: Fuel injection devices for internal combustion engines
IPC: F02M57/02
Filed: 1951-09-17
Abstract: 709,074. Fuel-injection pumps. MAYBACH, K. Sept. 17, 1951 [Sept. 16, 1950; July 6, 1951], No. 21757/51. Class 102 (1). In a fuel-injection pump combined with an injector nozzle, the injection characteristics are controlled by rotation of the piston 116 by means of a regulating sleeve 104 mounted on an intermediate sleeve 103 which receives transverse projections 113 on a sleeve 114 through which the piston 116 slides. Before mounting on the engine, the pump is calibrated and marks 142 on the intermediate sleeve 103 are brought to align with marks 141 on an adjustable disc 140 secured to the pump housing 102. During assembly on the engine, the lock nut 107 is loosened to free the regulating sleeve 104 on the sleeve 103 and the teeth on the sleeve 104 are brought into engagement with teeth 109 on the regulating rod 108 after which the marks 141, 142 are aligned and the nut 107 tightened to lock the sleeves 103 and 104 together. The several pumps on an engine can thus be matched at every dismantling. Alternatively, instead of the markings 141, 142, the sleeve 103 may be locked to the casing by a ring nut after calibration, this nut being released after the sleeve 104 is locked to the sleeve 103. Backlash between the teeth 109 and those on the sleeve 104 is prevented by a torsion spring 110. During the pump suction stroke, fuel is drawn through the passage 122 and a bore 125 in the piston which is fitted with a non-return valve 170. The commencement of injection is determined when the end 131 of the piston closes the by-pass port 127; the end 131 may be inclined to vary this point upon rotation of the piston. The end of injection is determined by an oblique groove 130 on the piston connecting a groove 133 in the cylinder to the by-pass port 128. The body 102 is attached to the engine by a clamp 135.

Title: Improvements relating to electroluminescent diodes and a method of manufacturing such diodes
IPC: H01L33/00
Filed: 1966-05-17
Abstract: <PICT:1086567/C4-C5/1> An electroluminescent diode has a first region of one conductivity type and a second region of opposite conductivity type formed by diffusing an impurity into the first region to a non-uniform thickness, ohmic connections being made to the first region and to a relatively thick portion of the second region.  The diode may be made by applying a semi-pervious masking layer 6 having a window 8 to the surface of an n-type gallium arsenide chip 2, diffusing zinc through the mask to form a P-type region 10 which is deep and degenerate below the window and relatively thin beneath the layer, and applying alloy (e.g. Au, Sn, In) contacts 12 to the opposite surface of the chip and to the area exposed by the window. The layer 6 may be made of SiO2 and may remain on the diode, its refractive index being approximately the square root of the refractive index of the semiconductor material and its thickness being an odd multiple of one quarter of the wavelength of the light to be emitted by the diode.  The gallium arsenide chip may be doped with Si, Te, Se or Sn.  In a modification a second semi-pervious layer is applied over the layer 6 and has a second window intersecting the window 8, so that the chip is exposed at the intersection of the windows. Different semi-pervious materials may be used, the relative thickness and permeabilities controlling the depth of diffusion.

Title: Method of refining pig iron
IPC: C21C5/32
Filed: 1963-05-31
Abstract: A method of refining pig iron to steel comprises blowing oxygen or an oxygen-containing gas on to molten iron contained in a bath caused to vibrate at natural frequency, the slag being maintained at least substantially solid during the refining until a short time before there is attained that carbon content at which it is desired to end the refining and thereafter the slag is liquefied and maintained in the liquid state until the completion of the refining.  On completion of the refining undissolved slag constituents may be dissolved by one or more of the following measures, viz: increasing the temperature; increasing the FeO content; addition of suitable fluxing agents.  At the beginning of the refining using a basically lined bath the slag may be adjusted to be super saturated with CaO for refining pig iron of high phosphorus content, or with 2CaO.SiO2 for refining pig iron of phosphorus content, or using an acidically lined bath, with SiO2 for refining pig iron of low phosphorus and silicon content.  The vibration of the bath may result from a circular reciprocating movement.

IPC: H04Q1/446
Filed: 1956-07-18
Abstract: 810,354. Pulse generating circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 8, 1957 [July 18, 1956], No. 22191/56. Class 40 (6). [Also in Group XXXIX] A multivibrator VT18, VT19 (Fig. 5) produces pulses at 800 c.p.s., the output from VT19 being fed to cathode follower VT20 and also via rectifiers MR10, MR11 to the toggle circuit VT10, VT11 which operates as a frequency divider, the 400 c.p.s. output of VT11 being fed to cathode follower VT12. The cathodes of the cathode followers VT12 and VT20, the waveforms at which are shown in Figs. 6(b) and 6(a), respectively, are connected via rectifiers MR12, and MR13, respectively, to the grid of VT13. When VT12 and VT20 are both cut off, MR12 and MR13 are both conductive and VT13 is cut off. With one only of VT12 and VT20 conducting the increase in the grid potential of VT13 is insufficient to cause VT13 to conduct, but with both these tubes conducting VT13 conducts to produce a train of pulses (Fig. 6(c)) during the coincidence of the 800 c.p.s. and 400 c.p.s. trains. The output from VT13 is differentiated by VT14 to give short positive pulses (Fig. 6(d)) which are applied to the flip-flop VT15, VT16 to produce pulses of the width required, which are fed to the cathode follower output stage VT17.
