Abstract: 1,230,462. Machine tool details. H. MULLER. 27 Aug., 1968 [15 Sept., 1967], No. 40902/68. Headings B3B and B3C. In a machine tool the tool carrier 1 is movable across a slide 2, which in turn is movable along a guideway 3, the carrier and slide each being provided with a braking means, which also clamps the carrier or slide in its adjusted position. Each of the braking means comprises a piston 10, Fig. 2, having a plate 15 screwed thereto, carried by the moving member i.e. the slide 2 or the carrier 1, and a spring steel member 16 connected to the fixed member 3. In operation, the slide or tool carrier is moved by a toothed belt 12, or a lead screw, hydraulic, or pneumatic fluid being supplied to the piston at 19, so as to move plate 15 into the released position. When the member has been moved to the required position, the fluid is exhausted from space 19 so that belleville washers 18 move the piston, plate 15 brakes the movement, and eventually clamps the carrier or slide. The engaging surfaces of members 15, 16 may be coated with synthetic materials, or molybdenum. In a modification, plate 15 is moved into the released position by springs, and the braking is provided by the fluid pressure. Work support 7 may be braked as described above.

Abstract: 1,232,252. Colour television. FERNSEH G.m.b.H. 30 Aug., 1968 [31 Aug., 1967], No. 41543/68. Heading H4F. Relates to an apparatus for reducing colour errors in the black and grey parts of the reproduced picture in a colour television system caused by differences in the blanking level of the three component signals, i.e. luminance and two colour difference signals. As shown, the apparatus comprises non-linear amplifiers 1, 2, 3 and 4 for each of the colour signals and the luminance signal, the input/output amplitude characteristic of each amplifier being shown. The input/output characteristic of the luminance amplifier 4 has an inverse relationship to the characteristics of amplifiers 1, 2 and 3. Three different components of the luminance signal Y 1  are then taken via resistors 51, 54 and 57 to be mixed with the colour signals. Hence, after mixir g at low signal amplitudes (i.e. towards the black level) the luminance signal predominates over the colour signal to give true black and grey shades, while at high signal amplitudes the amplitude of the luminance signal diminishes in comparison with that of the colour components.

Bobbins are doffed from spindles 3 by moving bobbin grippers 2 from an initial position towards and along the spindle axis to grip a wound bobbin, turning the spindle 3 relative to the bobbin to facilitate release of the bobbin from the spindle, and returning the bobbin gripper 2 and bobbin to the initial position.  As shown, the spindles are doffed by a carriage which moves on rails 29 along the row of spindles. The carriage is arrested by stop switches and the grippers 2 are lowered over the spindles 3. The grippers pneumatically grip the yarn wound on the bobbin and return to their initial position. As the grippers start rising, plates 8 move against pulleys 7 on the spindles and reciprocate to rotate the spindles. When the grippers have returned to their initial positions the bobbins are released from their holders and empty bobbin spools are fed from casing 37.

Abstract: 1,251,711. Photographic light-sensitive silver dye-bleach materials. EASTMAN KODAK CO. Jan.1, 1969 [Jan.2, 1968], No.33/69. Heading G2C. A photographic light-sensitive silver dyebleach material comprises a support and has coated thereon a light-sensitive layer comprising a photo-activatable metal oxide (i.e. a metal which when subjected to light will transfer and donate electrons to the water-soluble silver salt and thereby release metallic silver) with a watersoluble silver salt (i.e. silver nitrate, silver acetate, silver lactate or other silver salts (inorganic or organic) which are not less watersoluble than silver acetate), and in the same layer or in a contiguous layer at least one dye which is imagewise bleachable by the silver dye-bleach process. The metal oxide may be zinc oxide, titanium dioxide, antimony trioxide, or aluminium oxide. The said silver salt is usually coated at a silver coverage of 0À5 mg to 10 mg per sq. ft. The coloured image is produced by forming a silver-image by physical development of the exposed material defined above and bleaching the dye or dyes associated therewith imagewise in accordance with the silver image. Specification 1,251,712 is referred to.

Abstract: 1,252,803. Making integrated circuits. INTERNATIONAL BUSINESS MACHINES CORP. and MOTOROLA Inc. 15 Jan., 1969 [15 Jan., 1968], No. 2434/69. Heading H1K. The figures shown depict part of a wafer from which a plurality of integrated circuits are to be formed by division along lines such as 59, 61 of Fig. 13. In the use of a circuit the positive side of the main power supply is connected to region 1 and the negative side to region 5<SP>1</SP> (Fig. 13); the power is distributed by surface metallization which extends from these regions to the individual devices 8 (as illustratedin exploded view-in Fig. 1, not shown), and junction 28 provides decoupling capacitance across the supply. Fig. 6 depicts a stage part way through the manufacture. The structure has been formed from an N<SP>+</SP> arsenic-doped silicon starting wafer 1 at the surface of which N<SP>+</SP> channels 2 and P<SP>+</SP> regions 5 have been formed by diffusion of phosphorus and boron. (Separate masked diffusion steps may be used to produce regions 2 and 5 or the P<SP>+</SP> region 5 may be initially formed to extend over the whole upper surface of wafer 1 and the diffused region 2 then formed by counter doping). An epitaxial layer A is then grown on wafer 1 and dopants diffused from regions 2 and 5 most of the way to the upper surface of the layer. The structure of Fig. 10 is obtained from this by forming diffused separate N<SP>+</SP> and P<SP>+</SP> zones in the surface of the epitaxial layer A, by growing a second epitaxial layer B, and by diffusing dopants from the N<SP>+</SP> and P<SP>+</SP> zones into both of the epitaxial layers A and B. (The distance h in Fig. 10 shows the extent of epitaxial layer A. Regions 31 and 6<SP>1</SP> are those formed by out-diffusion from the N<SP>+</SP> and P<SP>+</SP> zone). The structure of Fig. 13 is obtained by further diffusion steps. A P-type diffusion continues the isolating channels 6<SP>1</SP> to the surface by doping regions 7<SP>1</SP> and forms the bases 47 of NPN transistors 8. An N-type final diffusion forms regions 4 and thus completes the extension of the N<SP>+</SP> region 1<SP>1</SP>, 2, 3<SP>1</SP>, 4<SP>1</SP> to the surface of the structure and forms the emitter regions 51, 53 of the transistors. Each completed circuit (formed by division along lines 59, 61) has silicon oxide passivation on its upper surface, a negative terminal metallization (39a, Fig. 1, not shown) making contact to part of region 7<SP>1</SP> and thus to the P<SP>+</SP> bulk 51, metallization for distributing negative voltage from parts of the regions 5<SP>1</SP>, 6<SP>1</SP>, 71 to the emitters, and metallization linking the collectors with the upper surface 4 of the N<SP>+</SP> region 1<SP>1</SP>, 2<SP>1</SP>, 3<SP>1</SP>, 4. The main positive supply terminal is formed by a molybdenum strip at the underside of the structure and upon which the circuit is mounted; attachment is made by gold-plating the body and terminal and by heating the system and applying ultrasonic energy.

Abstract: 1,258,183. Labelling machines. H. KRONSEDER. 4 March, 1968 [6 March, 1968], No. 11465/69. Heading B8F. Labels are taken from a magazine 13 and transferred to a labelling cylinder by transfer members 6 which follow a non-circular path and are given rotary movements about their own axes. Each transfer member is rotatably mounted on a lever 21 which is pivoted at 20 to a rotatable housing 5. The lever 21 carries a follower roller 19 engaging a cam groove 18 in a stationary disc 17 and is arranged to give the transfer member a path having substantially straight portions adjacent the label magazine and adjacent one or more glueing bands (not shown). Each transfer member is fast with a gear 26 meshing a gear 25 rotatably mounted on the housing 5 and fast with a lever 24 carrying a follower 23 engaging a cam groove 22 in the stationary disc 17. The transfer member is thus rotated so as to roll over a label to draw it from the magazine and is also rotated to bring its peripheral speed to that of the labelling cylinder (not shown). One or more glueing bands of adjustable length and spacing apply glue to the part or the whole of the surface of each transfer member prior to it reaching the label magazine.
