Patent GB-1106179-A (GB)
Title: Apparatus for indexing the work spindle in automatic lathes through predetermined angles of rotation
IPC: B23Q16/06
Filed: 1965-08-09
Abstract: 1,106,179. Lathes. INDEX - WERKE KOMM. GES. HAHN & TESSKY. 9 Aug., 1965 [8 Aug., 1964], No. 34078/65. Heading B3T. In an automatic lathe the spindle 10 is stopped in predetermined positions by means of an index disc 14 attached to the spindle and engageable by a click-stop device 28 which is freed from a holding device 26 when the spindle is rotating at a slow speed, the holding device being deactivated by at least one releasing member 34 rotating with the spindle. The stop bolt 28 is moved towards the disc 14 by an electromagnet 32. The releasing means consist of magnetic pins 34, 36, 38 which give impulses to a device 42. In operation, the speed of the spindle is gauged by the impulses transmitted to the device 42 by the south pole of the magnet 34. When the spindle is braked and has been slowed sufficiently, a clutch is operated to engage a slow-speed drive. Operation of the device 42 by the magnet 34 then causes release of the plunger 28 and stopping of the spindle. A drilling or milling operation is then carried out. When the operation is complete, the electromagnet 32 is de-energized and the plunger 28 is withdrawn, causing a switch 44 to be actuated to re-commence the slow-speed drive. The spindle is stopped again at the notches 18 and 22, the notch 20 being inoperative due to the absence of a magnet. A second magnet 50 at the notch 22 sets the electrical control circuit to prevent further operation of the plunger 28. If more than one indexing revolution of the spindle is required, such as for drilling a series of holes in the circumference of a workpiece and then tapping them, an electrical counter is provided. In a modification, an indexing cycle is started by applying pressure to a piston 168, Fig. 5, to raise it and actuate a slow-speed switch 184. It also raises a rod 202 which is engaged with a slotted lever 224 and swings it to rock a bell-crank 234 and bring a roller into the path of a dog 144 on the spindle 130. When the dog 144 rocks the bell-crank, the lever 226 moves the rod 202 to release a catch 194 and allow the plunger 156 to engage a recess 134. Movement of the plunger releases a switch 164 to stop the slow speed drive. Indexing of the spindle follows in sequence as before.

Title: Improvements in or relating to the distillation of organic acid mixtures
Inventor: MILLIDGE ALFRED FRANK
IPC: C07C51/50
Filed: 1955-11-29
Abstract: In a process for the distillation, in apparatus at least partly constructed of stainless steel, of a mixture of aliphatic acids, including a minor proportion of formic acid, obtained by the oxidation of hydrocarbons or ketones the corrosion of the stainless steel is minimized by the addition of peroxides (including organic peracids) to the mixture.  The acid mixture is obtained by the oxidation of lower aliphatic hydrocarbons with molecular oxygen and generally comprises an aqueous mixture of formic, acetic, propionic and butyric acids.  Peroxides mentioned are hydrogen peroxide, peracetic acid, performic acid, t-butyl hydroperoxide and mixtures either containing them or yielding them on contact with the acids. They are used in amounts generally not exceeding 5 per cent wt. and preferably less than 2 per cent wt.  The process is applicable in apparatus constructed from any available stainless steel, e.g. steels containing chromiums, nickel and molybdenum or titanium. Specifications 743,989, 743,990, 743,991, [all in Group IV (b)], and 771,992 are referred to.

Abstract: 521,803. Cathode-ray tubes. FERNSEH AKT.-GES. Nov. 24, 1938, No. 34214. Convention date, Nov. 24, 1937. Drawings to Specification. [Class 39 (i)] The control electrode of a cathode-ray tube comprises a diaphragm pierced with a plurality of apertures closely adjacent each other in at least one direction, the size of the apertures in relation to the distance between them being such that each aperture operates as a Wehnelt electrode, and an image of the electron beam in the plane of the control electrode is focused upon the screen. The variation of size of the focused spot with charge in the modulating potential is reduced, and cut-off is obtained sharply at a potential more positive than in normal Wehnelt electrodes. The apertures may be round, rectangular or hexagonal and arranged in a square, round or trapezoidal form or along a straight line. Preferably, the cathode surface is slightly larger than, and of the same shape as, the apertured area in the modulating electrode, and is parallel to it at a small distance. In one form a modulating electrode, 0.05 mm. thick, spaced 0.15 mm. from the cathode, has apertures, 0.15 mm. in diameter, spaced 0.2 mm. apart in a square of edge less than 1 mm. A variable-mu characteristic may be obtained by curving either the control electrode or the cathode surface or by using apertures of different sizes. The screen may be fluorescent or an element in a light-valve. The spot need not be modulated.

[Also in Division C5] In a process for deforming a metal at 600‹ C. or above, the workpiece is protected from oxidation and is lubricated during deformation by a powder mixture introduced between the workpiece and deforming tool, the mixture including a crystalline material having a space-lattice structure, and having a definite melting point which is higher than the -working temperature, the mixture being plastically deformable at the working temperature whereby it provides on the deformed workpiece a loosely adhering space-lattice crystalline oxide-resisting coating. The process may be hot extrusion, drawing, roller piercing of solid and hollow billets, Figs. 2-4 (not shown), or piercing ingots with backward extrusion, Fig. 5 (not shown). The workpiece may be pre-heated or may attain the working temperature as the result of its deformation. The mixture includes an oxide of the metal being deformed or of a metal having an affinity for oxygen at least as great as the metal being deformed. For the extrusion of steel, iron-oxide is used and may be mixed with amorphous substances such as glass powder which become liquid or viscous at the deformation temperature. The powder may also contain  FeSiO 3  or FeSiO 4 .Many specific examples are given of powder mixtures for the working of various alloy steels, copper base alloys, and chromium, niobium, molybdenum, tantalum and tungsten alloys. The mixture may be applied directly such as by a blower (6), Fig. 3 (not shown), or it may be mixed with a binder such as water glass and formed into a paste or compact. In a backward extrusion and piercing operation, Fig. 5 (not shown), the billet is coated externally with the powder mixture and loose powder or a compact is applied between the punch and.workpiece. Subsequently the coating is removed from the workpiece by stretching, drawing surface heating with a gas burner or by chemical methods.

Abstract: 1281699 Physically developed photographic plates bearing conductive metal images ITEK CORP 14 July 1969 [15 July 1968] 35289/69 Headings G2C and G2M A photo-sensitive layer having a thickness of less than 10 microns on a support therefor is exposed and then physically developed until the image formed is a conductive metal image adherently bonded to the support. The photosensitive entity may be silver halide, a photoconductor, anazo compound or a ferric compound. In the examples the photo-sensitive entity is titanium dioxide. The support may be aluminium, which may be silicate coated in Example 5 or iron. In Example 3 titanium dioxide is used without a binder. The support metal may be separated from the photo-sensitive material by an insulating layer which will photo-conductively insulate the photosensitive material from the support. The insulating layer may be aluminium oxide on an aluminium support. The photo-sensitive layer may be removed after image formation by washing. In Example 1 a silver image on an aluminium support is treated with a copperizing solution, the copper imaged plate treated with dilute H 3 PO 4  and the plate is then inked. In Example 2 a silver image is treated with 2-mercapto-benzothiazole and 85% H 3 PO 4  in water so that the silver image will accept greasy ink and the non-exposed areas will accept water. In Example 4 an additional treatment to that in Example 2 is effected by coating with a lacquer which adheres to oleophilic surfaces in preference to hydrophilic surfaces. Reference is made to Specifications 1281697 and 1281700.
