Title: Improvements in and relating to precision drilling and like machines
IPC: B23Q17/22
Filed: 1934-12-18
Abstract: 432,684. Eyepieces. LINDNER, H., 9, Lubarser Strasse, Wittenau, Berlin. Dec. 18, 1934, No. 36267. Convention date, May 14. [Class 97 (i)] [See also Group XXII] In adjusting the carriage of a metal-cutting &c. machine tool with the aid of a linear scale and a microscope, the coarse adjustment is effected by displacing the carriage relatively to the scale and the final fine adjustment is effected by moving the scale through the required small distance and then returning the carriage to the same position relatively to the scale. The table 1 of a machine such as a precision drilling machine carries a microscope 9, Fig. 2, and is moved by a screw 3 operated through a coarse adjustment hand wheel 4 and a fine adjustment hand wheel 5 acting through a worm gear. A cylindrical scale 8 having a helical line engraved thereon by a diamond &c., is rotatable in bearings 6, 7 on the machine bed by means of a hand wheel 12 and a scale and vernier 13 which reads in thousandths of a millimeter of axial displacement of the helix. If the pitch of the helix is too fine to permit numerals to be indicated on the scale 8, a linear scale 11 may be provided on the bed to co-operate with a pointer on the table 1 or the microscope. Alternatively, the scale 8 may be rotatably mounted on the table and the microscope 9 fixed to the machine bed. In operation the scale 8 is rotated until the helical line thereon appears between two lines on the microscope, the table is displaced by the hand wheel 4 through the required number of units of length, (e.g., millimeters), the scale 8 is rotated to displace the helical line axially by the required number of thousandths of a millimeter, and the table is then moved by the wheel 5 until the microscope lines again straddle the helical line on the scale 8. The procedure may be varied by effecting the fine adjustment first, or by making the coarse adjustment in excess of the required displacement and the fine adjustment in the reverse direction. In a modified construction a scale 8, Figs. 7 and 8, with helical or straight graduations is splined by a key 22 in a fixed bearing 7 and is displaced axially by a micrometer screw 24 having a graduated hand wheel 27 reading in thousandths of a millimeter. The scale is pressed axially by a spring 23 so as to engage a ball 26 thereon with the end of the screw 24 and a labyrinth seal 25<a> prevents ingress of dirt between the wheel 27 and the nut 25. The scale 8 may be on the machine bed and the microscope 9 on the table 1 or vice versa. The adjustment of the table is effected as described above except that the fine adjustment is determined by axial motion of the scale 8 instead of by rotation thereof. The microscope readings may be observed from a point near the controls 4, 5, by means of a device 19, Fig. 11, wherein light from a source 14 is transmitted by a prism 16 and lens 15 onto a scale 8 and thence by prisms and lenses 17, 20 to an eye piece 21, the device being rotatable about the axis of the tube 19<a>. Specification 431,999 is referred to.

Title: Process for preparing white oil
Inventor: WILSON WILLIAM AMOS
IPC: C10G17/06
Filed: 1956-11-30
Abstract: White oil is prepared by first treating mineral oil to form, neutralize, and remove sulphonic acids, and then mixing the treated oil with a minor proportion of water and sulphur trioxide to form an acid containing 60-80 wt. per cent of free SO3. The oil may be treated in the first stage with oleum containing, for example, 20-30 per cent SO3, or with liquid or gaseous sulphur trioxide.  The sulphonic acids may be separated from the oil by settling or centrifuging and the oil then neutralized with caustic soda or sodium carbonate and the soaps formed extracted with alcohol, e.g. isopropyl alcohol.  In the final acid treatment the water and SO3 may be used in proportions which would form an acid present in a proportion of 8-15 per cent by weight. Both acid treatments may be carried out in more than one stage. The refined oil may finally be clay filtered. Petroleum distillates, e.g. lubricating oils boiling at 600-1000 DEG F., may be treated; these lubricating oils may be solvent extracted and clay treated.

Title: Improvements in colour lighting apparatus
IPC: F21S8/00
Filed: 1946-12-12
Abstract: 646,642. Theatre lighting. WILLIAMS, R. G. Dec. 12, 1946, No. 36761. [Class 132 (i)] [Also in Group XI] A colour lighting apparatus comprises the combination of means so arranged as to split each of several major beams of different colours into a plurality of component beams, means so arranged as to transpose at least some of the component beams so as to mingle the colours, and means so arranged as to combine the component beams into a unitary beam in their transposed relationship. Four light sources giving light of four different colours as by coloured screens &c. are arranged each at a corner of a rectangle RGBW, Fig. 4, the points B, W (not shown) being vertically below the points R, G, respectively. The light from each source is reflected by a parabolic reflector, e.g. 3 or 4 and projected forwardly as parallel beams e.g. 1R and 1G, which pass through nests of black masking rings 5 and 6 which substantially prevent the passage of light direct from the sources. The beams 1R, 1G are divided by reflectors 7, 8 which deflect component beams R2, G<SP>1</SP> and allow beams R<SP>1</SP>, G<SP>2</SP> to pass straight ahead. After crossing the beams R2, G<SP>1</SP> are again deflected by reflectors 9, 10 to emerge parallel with the beams R<SP>1</SP> and G<SP>2</SP>. In an alternative construction the black rings 5 may be replaced by lenses formed with circular prisms. Alternatively, no reflectors may be employed, the direct light from the sources R, G &c. being passed through a prismatic lens system to produce the parallel beams R<SP>1</SP>, G<SP>2</SP> &c. and the crossing beams R<SP>2</SP>, G<SP>1</SP> &c., and a further prismatic lens system is employed to render all the emergent beams parallel. As shown in Fig. 6 the major beam directed rearwardly from each source R, G may be split into component beams and the required transposition effected by reflectors 13, 14, H, 16 the reversed beams R<SP>2</SP>, G<SP>1</SP> being masked by plates 19, 20 and directed to refracting prisms 17, 18 to emerge parallel with the beams R<SP>1</SP>, G<SP>2</SP> also masked by the plates 19, 20. In a further modification the four major beams are produced by a single light source by four reflectors and a multi colour screen may be interposed between the sources and the reflector so that each reflector receives light of a particular colour. Specification 640,693 is referred to in the Provisional Specification.

Abstract: 810,631. Injection-moulding. DOW CHEMICAL CO. Dec. 3, 1956 [Dec. 27, 1955], No. 36912/56. Class 87(2). An injection moulding apparatus for moulding articles with little or no sprue comprises a mould having a recess in a wall providing access to a gate, and an injection nozzle having on its periphery a shoulder which abuts said wall in the recess and aligns the nozzle whilst the latter is seated in sealing contact with the inner end of the recess and in communication with the gate. A two-part mould 4, 5 has, in the part 4, a recess 9 having a hemi-sperical end wall which, where is surrounds a gate 12, is flexible. An injection nozzle 19 has a " spout " 16, with a hemi-spherical end, and has a frusto-conical seating shoulder 14 to engage a similarly shaped seating 10 of the recess. The shoulder 14 has grooves 15 to reduce heat, transfer from the nozzle to the mould and the spout 16 may have heaters placed around it. In operation, with the mould closed, the nozzle is brought to the mould half 4, the seatings 10,14 engage and the hemi-spherical ends of the recess and spout meet. As the pressure of the injected material in the mould increases the portion of the mould recess surrounding the gate 12 flexes towards the spout and the sealing pressure between the spout and gate increases. Due to the thinness of the gate periphery the moulded article is substantially sprueless.
