Title: Liquid detergent compositions
IPC: C11D3/14
Filed: 1960-06-04
Abstract: An aqueous detergent composition comprising (a) a non-acidic alkali metal salt of a phosphoric acid having a molecular weight below 400, (b) an aniomic detergent, and (c) a fatty acid alkanolamide, contains a finely divided water-insoluble abrasive material in stable suspension. The phosphate (a), which comprises 2-45% of the liquid medium, is preferably sodium or potassium pyrophosphate or tripolyphosphate. The detergent (b) is preferably a mixture of soap with an alkylaryl sulphonate such as sodium dodecylbenzene sulphonate, an alkly sulphate, or an acylaminoalkane sulphonate, but acyl isethionates are not recommended the weight ratios of synthetic detergent to soap should be 1:1 to 4:1. In general, component (b) should comprise 1-10% of the liquid medium, but if no soap is present, the synthetic detergent should not be less than 3%, and if no synthetic detergent is included, the soap should not be less than 1,2%. Although component (c) may consist of an isopropanolamide, a glycerolamide or a tris-(hydroxymethyl)-methylamide, it is preferred to use the mono- and di-ethanolamides of lauric acid in amounts of 1-10% of the liquid medium. The abrasive may consist of felspar, pumice, kieselguhr, emery, or carborundum, but is preferably silica, and is suitably of such a particle size that it all passes a sieve of 104 micron mesh and 80% at least passes a sieve of 53 micron mesh coarser abrasive particles may however be used for special purposes. In general the abrasive constitutes 20-50% of the total composition. The compositions, which may also include sodium carbonate, bicarbonate and sulphate, borax, germicides such as p-chloro-m-cresol and bis- (3:5:6-trichloro-2-hydroxyphenyl)-methane perfume, such as pine oil, and colour, should not contain any hydrotrope such as sodium xylene sulphonate. The ionic components present may be used in the form of the alkali metal, ammonium, or substituted ammonium salts. The compositions are prepared by heating and stirring the phosphate with twice the weight of water to 60 DEG C., cooling to 40 DEG C., adding the solution obtained by dissolving the detergent in the rest of the water at 60 DEG C., cooling to 40 DEG C., and then adding successively the alkanolamide, the abrasive, and any other ingredients. In the Provisional Specification no limit is imposed on the molecular weight of the phosphate (a), and the alkanolamide (c) may be replaced by any non-ionic surface active agent, several of which are specified.

Title: Disk-brake cleaning method
IPC: F16D65/00
Filed: 1966-12-14
Abstract: A method for grinding the rotatable braking disc of a vehicle disc brake comprises rotating the braking disc whilst in position on the vehicle and applying a grinding member or grinding members to a braking surface or the braking surfaces of the disc. To remove rust and dirt from brake discs of disc brakes installed in a motor vehicle, the friction pads in the brake caliper are replaced by grinding members, the vehicle is driven and the brakes are applied several times. Each grinding member comprises a grinding block 2, Fig. 1, a backing plate 1 and an interposed plastic heat insulating layer 3, all secured together by adhesive. The block 2 may comprise silicon carbide with an organic or ceramic binder. The installation dimensions of the grinding member are the same as those of the friction pad which it replaces. The grinding member engages a wider annular surface of the disc than that engaged by the friction pad. Alternatively, the vehicle is jacked up and the wheels removed. The brake disc 4, Fig. 2, is rotated by a friction roller 10 mounted on an electric drill and applied by hand to the periphery of the disc. Grinding blocks 2a, Fig. 3, mounted on a pair of tongs 6 are applied to the disc, the tongs being supported against the brake caliper. In a modification, use is made of a mobile stand 9, Fig. 4, on which is mounted a brake-like device 7 arranged to apply pressure to a pair of grinding members, a frictional drive roller 8 being provided.
Patent ES-336936-A1 (ES)
Title: Saturable reactor pincushion correction circuit
IPC: H04N3/237
Filed: 1967-02-17
Abstract: In an arrangement for correcting pin-cushion distortion utilizing a known circuit including a transductor 9 (Fig. 1) having a non-linear B/H characteristic, distortion of the field scanning sawtooth wave, which is supplied to the field output transformer 5, due to the varying inductance of winding 16 of the transductor, is compensated by the provision of a third winding 26 coupled to winding 16 on the transductor core (Fig. 2, not shown) the voltage induced in which is introduced, with proper regard to polarity, into the negative feed-back circuit of the field amplifier stage 4. This results in a predistortion of the sawtooth across winding 18 which distortion is then cancelled by the undesired component due to winding 16. As shown, winding 26 is connected between the field sawtooth capacitor 21 and a feed-back winding 25, the amount of feed-back being such that the control grid of 4 receives about 1/ 10 of the amplitude of the sawtooth voltage across capacitor 21. The actual waveforms developed in the operation of the circuit are described with reference to Figs. 3 and 4 (not shown). In a modification, the coils 25 and 26 are connected in parallel instead of in series (Fig. 1a, not shown). Fig. 5 shows a modification in which an RC circuit comprising resistors 31, 32 and capacitor 33 is included in the circuit of the feed-back winding 25 to eliminate line fly-back pulses due to the line deflection coils 3 (fed from line sawtooth generator 1) these resistors together with a further capacitor 34 also forming a peaking network to eliminate pulses from the negative feed-back voltage. Fig. 5 includes an additional winding 35 on the transformer 5 which is utilized as a feed-back winding to make the field deflection stage, triggered by field deflection pulses supplied to capacitor 36, self-oscillating. Fig. 6 shows a further arrangement, not employing negative feed-back, which utilizes a boot-strap stage 38, the cathode resistor 39 of which supplies a sawtooth voltage (produced across capacitor 21) to the grid of a triode 41 forming the field output stage, the arrangement being self-oscillating. To compensate for the effect of winding 16, the voltage across winding 26 is introduced into the grid circuit of stage 41 and line fly-back pulses are removed by the network comprising resistor 44 and capacitor 43. In all of the embodiments parabolic and " S " components are added in known manner. The thermionic valves may be replaced by transistors.

Title: Processes and devices for the cutting or machining and burnishing of ball surfaces of workpieces
IPC: B23B5/40
Filed: 1967-03-21
Abstract: A ball turning and burnishing machine comprises a chuck 1 on which a workpiece 2 is mounted and which is rotatable about an axis a, a table 6 rotatable alternately in opposite directions about an axis b which intersects the axis a at a point defining the centre of curvature of the ball', a cutting tool 8 mounted on the table to one side of the axis a and a burnishing tool 11 on the other side of the axis a, diametrally opposite the cutting tool. Operation.-With the table 6 in the position shown in the Figure the tool 8 is moved hydraulically to apply the cut and the burnishing roller 8 is retracted from the workpiece. The table is rotated in the direction of the arrow 13 and the workpiece rotates about the axis a, to form a spherical surface. When the tool 8 reaches the position 81, the tool holder contacts a stop (not shown) which causes the table to stop, the tool to be retracted and the burnishing roller 11 which is now in the position 111 to be advanced into contact with the work. The table 6 then rotates in the opposite direction so that the burnishing tool works the turned surface.
