Title: A power drill lubricating system
IPC: B23B45/16
Filed: 1966-04-27
Abstract: 1,091,540. Percussive drills. F. DUSS, [trading as FRIEDRICH DUSS, MASCHINENFABRIK]. April 27, 1966 [May 7, 1965], No. 18396/66. Heading B4C. [Also in Division F2] A power drill has an axially reciprocable drilling tool actuated via an air-cushion, the latter also serving to effect lubrication of the power drill by controlling the flow of lubricant from a reservoir, a valve being closed when the pressure of the air-cushion is high and being opened when the pressure is low. In an embodiment the piston 5, Fig. 1, is reciprocated in a cylinder 1 of the power drill by means of an electric motor, via gears 15, 16 and a crank-drive 3, 4. The air-cushion 6 is formed in the cylinder 1, the piston 5 forming one end of the air-cushion and a mass-element 2 forming the other end, the mass-element 2 also engaging the drilling tool. A shaft is also driven by the electric motor, via gears, and carries rollers 9, having notches 9a, Fig. 2, therein. The power-drill is provided with an oil reservoir 23, Fig. 1, which comwith the air-cushion 6 via a valve 19 and a passage 22, the latter also being connected to the interior 26 of the housing of the power drill through a radial bore 24. In use, the forward stroke of the piston 5 synchronizes with the opening of vents 7, 8 in the cylinder 1 by the rollers 9 and the air-cushion receives maximum pressure. The valve is closed by the pressure of air in the passage 22 so that oil cannot flow from the reservoir 23. The return stroke of the piston synchronizes with the closing of the vents 7, 8 and, as the pressure of the air-cushion is at a minimum, the valve 19 is opened and oil is sucked from the reservoir 23 and delivered, via the passage 22, to the aircushion 6. As the piston again makes a forward stroke, oil-entrained air is forced into the interior 26 of the housing, via the vents 7, 8 and the notches 9a in the roller 9 and via the radial bore 24. Thus the interior 26 is supplied with an oilmist. Oil mist from the air-cushion 6 may also be passed through bores in the mass element 2 to a portion 18 of the cylinder 1. Oil in the reservoir 23 may be passed to the valve 19 via capillary tubes 27, Fig. 3, or via a flexible tube the free end of which has a weight secured thereto.

Abstract: 470,668. Shaping curved surfaces. SYKES, W. E. July 6, 1936, No. 18728. [Class 83 (iii)] Gear-cutting ; tools.-A method of cutting metal comprises employing a cutting tool having a number of peripheral cutting edges arranged so that rotation of the tool about its axis brings successively each part of the cutting edges into tangential relation to a fixed plane, and relatively reciprocating the tool and the metal work through a distance slightly greater than the distance between adjacent cutting edges, so that each cutting edge in its cutting movement enters the path traversed by the next adjacent cutting edge. The cutter 80, Fig. 4, which may be a single block or built-up of a number of discs, may have circular or helical teeth and is held in a block 70, carried by an adjustable horizontal slide 46 mounted on a further slide 40 which is adapted to be reciprocated in guideways 15 provided on an upright 12 of a machine. The slide 40 is engaged at one end, Fig. 4, by an adjustable eccentric 69 carried by a shaft 66 which is rotated at high speed by an electric motor 65. This motor also drives through gearing in a case 64 and bevel gears 104, Fig. 2, a splined shaft 102 which drives a cam 100 in the housing 101. The cam operates a tappet 96 and a wedge 90 is reciprocated to move the block 70 horizontally to relieve the cutter at the end of each cutting stroke and to feed it into the work again at the beginning of the next cutting stroke. The workpiece, such as a piston P, is carried on a mandrel 27 and may be slowly rotated by reduction gearing and a motor 28 which are carried on an indexable table mounted on a slide 16 adjustable transversely of the cutter. Stepped work may be cut by using a stepped cutter. A modified cutter 47, Fig. 15, adapted for carrying out the above method to cut straight or helical gears, comprises a number of separate discs T<1>-T<4> with toothed peripheries, which are set up by positioning a master gear in place of the work.

Patent GB-650133-A (GB)
Title: Phenol-modified acetone resins
IPC: C08G2/00
Filed: 1948-07-13
Abstract: A phenol - modified formaldehyde - acetone resin is made by condensing a mixture of phenol, formaldehyde and acetone in the presence of a water-soluble inorganic base in amount to impart to the mixture a pH value between 9.5 and 11.5, the formaldehyde and acetone being present in amount of one to two mols. of formaldehyde per mol. of acetone and the phenol between 2 and 35 per cent by weight of the acetone.  For equimolecular proportions of acetone and aldehyde 2-10 per cent of phenol is preferably used, and for larger proportions of aldehyde, 10 to 35 per cent of phenol is preferred.  Cresols, xylenols and p-phenylphenols may replace phenol, and paraformaldehyde may replace formaldehyde. Catalysts used, e.g. in amount of 1-2 per cent by weight of the reactants, are alkali and alkaline earth metal hydroxides.  In examples, (1) equimolecular amounts, and (2) 2 : 1 molar proportions of formaldehyde and acetone are reacted with phenol in the presence of caustic soda.  The exothermic reaction is controlled by cooling to below the boiling point of acetone; unreacted acetone is removed by distillation and the mass is dehydrated by vacuum distillation.  The resins, to which additional hardening catalysts, e.g. diethylamine, may be added, may be used for making laminated articles, by applying a varnish of the resin in alcoholic solution to the surface of paper, wood veneer or cloth, and evaporating the alcohol, the treated sheets being then assembled into a stack and subjected to heat and pressure.  In example 3 (cancelled) of the Specification as open to inspection under Sect. 91, formaldehyde (2.6 mols.) is reacted with acetone (1 mol.) in the presence of caustic soda, and the reaction mixture is condensed in the presence of caustic soda with phenol in amount of 172.5 per cent by weight of the acetone. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,152,706. Lasers; discharge lamps. INTERNATIONAL STANDARD ELECTRIC CORP. 29 April, 1966 [30 April, 1965], No. 18859/66. Headings H1C and H1D. A discharge tube in which stimulated emission of radiation may be produced includes a discharge space of annular cross-section containing a gaseous active medium and defined laterally by inner and outer walls of the vessel, and is provided with a coil for producing a discharge in the space when supplied with radio-frequency energy. The spacing between the walls is selected to correspond to the skin-effect depth at the frequency of the r.f. supply. Coolant is passed through the vessel inside the inner wall and also through the hollow r.f. coil. The discharge space contains helium and neon at reduced pressure and mirrors are provided at each end to form a resonant cavity for producing laser action. If the pumping energy is sufficiently high, several oscillatory modes corresponding to a desired energy transition are produced at various positions around the annular active medium, as well as several modes corresponding to other, undesired, transitions. In a first embodiment (Fig. 2, not shown), in which the vessel walls are cylindrical, a carrier is therefore provided between one mirror and the active medium and on this carrier are provided " compensators " and " mode selectors." The compensators may be transparent plates having a thickness of about one millimeter and arranged obliquely to the radiation path, or metallic needles. The compensators are placed in line with the axes of the desired modes and couple the modes between themselves. The output may be focused by a lens. Undesired modes are suppressed by opaque masks and non-axial modes may be prevented by means of longitudinal opaque partitions in the active medium or outside of it. In another embodiment (Fig. 3, not shown), the vessel walls each form a frustum of a cone and the modes form progressive waves around the active medium. The desired modes are selected by providing small shutters having the desired angular periodicity around the axis of the cones. The output is passed through a prismatic ring and a lens to focus it to a point. The compensators used in the previous embodiment may be used but are not essential. The progressive waves rotating in one direction may be selected at the expense of those rotating in the opposite direction by means of a diaphragm with holes spaced around it. It is stated that the " cones " may have hyperboloidal sections.

[Class 103 (i)] An automatic slack-adjusting device is embodied in the trunk piston of a brake-operating cylinder. The piston proper 1 prevented from rotation by the engagement of ribs 4 thereon with guides provided in the cylinder 2, carries a rotatable trunk member 6 guided by the endpart of the cylinder extension 14. The piston rod 8 is connected to the brake rigging at 20 and by a pivot 9 or a universal joint to a thrust member 7 having screw-threaded engagement with the trunk member 6 rotation of which in one direction is prevented by engagement of ratchet teeth thereon with a pawl 15. A ratchet sleeve 11 rotatable on the trunk 6 is engaged with ratchet teeth 10 on the trunk by a spring 16. During outward movement of the piston the sleeve 11 is rotated by engagement of a roller 12 thereon with a helical groove 13 formed in the cylinder extension 14 and if this movement is excessive the ratchet device slips a tooth so that during the return movement of the piston the trunk 6 is rotated and the non-rotatable member 7 is thus displaced axially relatively to the trunk to take uo the excess of slack. The trunk is provided with a collar or head 19 by which it may be manually operated to apply the brakes. Specification 426,581 is referred to.
