Abstract: 1,052,925. Surgical pads. JOHNSON & JOHNSON. Sept. 12, 1963 [Sept. 13, 1962], No. 35974/63. Heading A5R. An absorbent pad is made with a curved or concave shape by bonding a layer of orientated plastic material to an absorbent layer and then shrinking the plastic material, as by heating. In one form of apparatus wood pulp board 26 is passed through a comminuting mill 30 which reduces it to individual fibres which are laid on a conveyer as a continuous bat. A film 34 of oriented plastic material is supplied with adhesive at 38 and laid over the top surface and sides of the bat, to which it adheres. It is then cut into individual pads which are enclosed in a web of non-woven wrapping material 48 and the latter is cut, between pads, and these are packed against each other, as at 10, before being passed through an oven 58 in which streams of hot air are directed against the lateral edges of the pads. This causes shrinkage of the film and buckling of the pads to a longitudinally arcuate shape. In another form of apparatus the pads are initially shaped in a mould, prior to heating so that film of less strength can be used. It is further proposed to bond the layer of film between the absorbent layers having different resistances to bending and also to control the shrinkage of a film layer to produce concave pad.

[Also in Division D1] An aqueous dispersion comprises fibers of chrysotile asbestos and a water-soluble soap, with or without another anionic surface-active agent, and also contains a water-soluble substance or mixture of water-soluble substances capable of reacting with and precipitating the soap in an amount that is more than any natural hardness of the water in the dispersion, but not enough to coagulate the dispersion. Watersoluble substances referred to are aluminium sulphate, lead nitrate, copper sulphate, zinc chloride, calcium chloride, magnesium sulphate, hydrochloric acid and sulphuric acid. They may be first dissolved in water and then added slowly with thorough mixing into the dispersion, or may be dissolved in the water from which the dispersion is prepared. The dispersions may then be used to form coherent bodies, see Division Dl, by reacting with further quantities of precipitant. The treatment improves the smoothness, flow properties and stability of the suspension and strengthens the coherent bodies.

Abstract: 1,225,862. Colour television. BRITISH RADIO CORP. Ltd. 3 July, 1969 [4 July, 1968], No. 32048/68. Heading H4F. Brightness-control circuit for a colour television receiver comprises a pulse generator coupled to the luminance channel which generates a recurring pulse of which the amplitude and sign are manually-variable, the pulse having a leading edge at the end of each line-blanking interval and a trailing edge at the beginning of the next succeeding line-blanking interval, whereby the level of the video portion of the luminance signal can be adjusted in dependence upon the amplitude and sign of the added pulse without an accompanying adjustment in the level of the front and back porches of the linesynchronizing pulses. Thus the front and back porches of the line-synchronizing pulses are always at black level despite adjustment of the brightness control. The recurring pulses are also added throughout the frame synchronizing intervals, the tips of the synchronizing pulses being first D.C. restored. The combined luminance signal and recurring pulse are applied to an amplifier or to three amplifiers for controlling the three guns of the receiver CRT, and the or each amplifier includes a loop circuit embodying a back-porch clamp. The chrominance signals may be combined with the luminance signals in the three amplifiers.

In the arrangement shown, a pair of diametrically opposed fluidized bed containets 23, 24 are provided, and a pair of diametrically opposed slurry containers (25, 26), Fig. 2 (not shown), are mounted on platforms which are rotatable whereby the slurry is maintained in suspension. The spider 10 is vertically displaceable by an air cylinder 27 whereby the platforms are immersed in each container and, upon raising therefrom, the spider is then incrementally rotated through 90 degrees, by an air cylinder 11 actuated rack-and-pinion arrangement 12, whilst each spindle 19 is simultaneously rotated about the spider arm by the engagement of a stationary circular rack 16 with a pinion 15 on a rotatable sleeve assembly 14, 18; each shaft 19 being simultaneously rotated about its own axis by the engagement of a bevel gear 20 thereon with a fixed bevel gear 21. One of the slurry containers (25, 26) may contain an acidic slurry and the other an alkaline slurry and the containers 23, 24 may contain a fluidized bed of refractory material. In an alternative arrangement, a container of acidic slurry is followed either by a refractory fluidized bed container and then by a container of alkaline gas or by the fluidized bed incorporating an alkaline salt. When an alkine slurry is employed, the container thereof is either followed by a fluidized bed thereof and then by an acidic gas container, or by the fluidized bed containing an acid salt.

A machine tool comprises supporting means for a workpiece adjacent a bed on which a slide is mounted for reciprocation towards and away from the workpiece. The slide carries a workpiece-engaging wheel or like workpiece-engaging rotary member whose axis extends substantially horizontally and transversely of the direction of reciprocation of the slide, and means are provided for advancing the slide to bring the wheel or like member into engagement with the workpiece. Means are also provided for raising the slide to bring an upwardly directed guide face thereof into face-to-face frictional engagement with a downwardly directed face of rail means mounted on the bed. The arrangement is such that interaction between the wheel or like member and the workpiece tends to raise the slide to increase the frictional force between said faces.

In a nuclear magnetic resonance spectrometer for airborne survey, parasitic magnetic fields due to the rotor shaft of a helicopter are compensated by arranging two magnetometer heads T 1 , T 2  in line with the rotor axis, the spacing Sx between the heads being small compared with the distance x between T 1  and the barycentre, x being large compared with shifts in the position of the barycentre during manoevring and changes in loading of the helicopter. A control signal proportional to the difference in field strength at T 1  and T 2  is used either to adjust current in compensating coils situated at the barycentre or to correct the output of one of the heads. As shown, T 1  and T 2  are mounted in a non-magnetic glass-fibre reinforced plastics tube 24 pivotted at 26. Alternatively, a telescopic tube may be used having its axis along the chain-dotted line. In Fig. 2, head T 1  and amplifier 30 form a spin oscillator magnetometer. The output e 1  of frequency meter 34 is proportional to the field at T 1 . Head T 2  is a nuclear filter producing a phase shift so that the output e 2  from phase meter 40 is proportional to the difference in field strength at T 1  and T 2 . A variable gain amplifier 42 amplifies e 2  in the ratio x/3 Sx and difference amplifier 44 produces the corrected output e proportional to the field intensity. A mathematical analysis and suitable values of x and Sx are given for measuring the earth's field and for detecting anomalies. Correction for rate of turn of the helicopter may be provided using signals from rate gyros in the navigational equipment of the helicopter. Optical pumping magnetometers may be used.
