Title: Threading implement for forming threads on workpieces
Inventor: CUMMINGS EDGAR HERBERT
IPC: B21H3/04
Filed: 1966-03-17
Abstract: 1,100,503. Rolling threads. NATIONAL ACME CO. 17 March, 1966, No. 11801/66. Heading B3M. A thread rolling head includes rollers 14 mounted on eccentric spindles 30 within a frame 13 the rollers being movable into and out of engagement with a workpiece in response to axial movement of a ring 53, slidably mounted on a shank portion 16 of the head. The spindles 30 are provided with pinions 32 which mesh internally with a ring gear 33, rotation of the gear causing rotation and hence radial movement of the rollers. The rollers include annular thread forming grooves, and are skewed slightly to the axis of the head. The frame 13 carrying the rollers is bolted to a main shank portion 12, a drive bushing 36 being housed within the shank portion and in splined connection with the gear 33. A spiral spring 38 acts between the bushing 36 and shank portion 12 to tend to rotate the bushing, and thereby the gear 33, in a sense to release the rollers 14 from a workpiece. A lever 41, provided with an annular central section 42 and a radially projecting arm 44 carrying a roller 45, is biased by a spring 46 to the position shown. In this position the arm 44 'engages with a stepped surface formed within the shank portion 16. Rotation of the lever 41 together with the bushing 36 under the bias of the spring 38 is thus prevented. By moving the ring 53 axially towards the right the lever is moved against the bias of spring 46 and out of engagement with the stepped surface. The spring 38 immediately rotates the bushing 36, gear 33, pinions 32, and rollers 14. Movement of the ring 53 in the opposite direction resets the arm 44 into engagement with the stepped surface, generally triangular cam surface 52 within the ring 51 serving to move the roller 45, and hence the arm, in the appropriate direction. Either the rolling head or a workpiece can be rotated during rolling.

Patent GB-591303-A (GB)
Title: The manufacture of new and improved resol compositions
IPC: C08G12/36
Filed: 1945-05-04
Abstract: A resol is prepared by condensing a methylol derivative of an aliphatic diurea of the general formula H2N.CONH(CnH2n).CONH2, where n is an integer not greater than 10, with a methylol derivative of an aminotriazine at a temperature below that at which a resite is formed.  The condensation may be carried out in a mutual solvent for the reactants, such as water or an aliphatic alcohol, at a pH of 7-10 and over a temperature range of 50-100 DEG  C., the preferred ratio of aminotriazine derivative to methylol diurea being between 0.1 : 1 and 0.2 : 1.  The aliphatic diurea may be ethylene diurea or a polymethylene diurea as described in Specification 530,267 and suitable aminotriazines are triaminotriazine, substituted triazines and their methylol derivatives as described in Specification 583,720. The diurea derivative is preferably used in the form of an aqueous solution with which a suitable filler is impregnated, the water evaporated and the preformed methylol aminotriazine admixed; alternatively, the triazine derivative is introduced into the aqueous solution of the methylol diurea.  Fillers and accelerators, for example one that yields an acid on hydrolysis, may be added before or after evaporation of the solvent, the preferred filler being 0.2-1.0 part by weight of the weight of the resol of wood flour or a -cellulose, added before evaporation of the solvent.  In the example an adhesive is prepared from hexamethylene diurea, 37 per cent formaldehyde and trimethylol melamine and employed to bond birch veneers.  In the Specification as open to inspection under Sect. 91, the mixing of an aliphatic diurea of the general formula NH2.CO.NH.CH2 (CnH2n)NH.CO.NH2, where n is an integer, with a methylol derivative of an amino-triazine at a temperature below that at which a resite is formed is described.  The resol may be prepared by adding an excess of formaldehyde over that required to prepare the methylol diurea to the diurea and the methylol amino triazine prepared from the excess before the solution is evaporated.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of gears
IPC: B23F21/24
Filed: 1938-04-14
Abstract: 495,944. Toothed wheels and pinions. GLEASON WORKS. April 14, 1938, No. 11603. Convention date, Sept. 17, 1937. [Class 80 (i)] [Also in Group XXII] Both members of a bevel gear pair may be form cut without rolling generating movements by a rotary cutter which has a number of radial blades with concave arcuate side cutting edges arranged part way round the periphery with a gap between the first and last blades to permit indexing the work without withdrawal of the cutter. Both sides of the blank teeth may be finished simultaneously or each side may be finished separately. During roughing the cutter rotates about a fixed axis 56 and the blank 20 is positioned so that a radial line passing through the centre of the tooth space is perpendicular to the cutter axis. For the finishing cuts the sides are of arcuate profile, Fig. 2 showing the profile 31 of the blade which finishes the large end of a bevel gear tooth and 33, Fig. 3, showing the profile of the blade which finishes the small end. The centres of curvature of the various blades which cut at intermediate points along the tooth are shown at 39-41. The profiles have a common tangent preferably at a point 50 at or near the blade tips and for finishing the side 23, a radius 51 passing through point 50 is located perpendicular to the outer axis. Similarly for finishing the side 24, a number of finishing blades with circular profiles of different radii are provided and the blank is positioned so that a radius through the point 57 at the tip of profile 24 is perpendicular to the cutter axis. During the finishing stage, the cutter is fed relatively along the teeth to the point 56<1>, the differently curved profiles of the finishing cutters coming into action at different points along the teeth as this feed progresses. The tooth bearing of a pair cut in the above manner may be controlled by varying the inclination of the lines of centres 35... 37, Fig. 3, as described in U.S.A. Specification 1,733,326. Where both sides of the teeth are to be cut simultaneously, the gear member 60 is cut by a cutter having a centre at 71. There is no relative feed along the teeth and the blades have constant profile curvature. Each blade may have opposite cutting edges or alternate blades may cut on opposite sides of the gap. The gear is thus form cut with a concave root line. When the pinion 65 is to be cut, Fig. 6, there is a relative feed movement about an axis 95 such that the distance 95, 96 is about equal to the cutter radius 71 ... 98. In this way the pinion has a convex root line which matches the concave root line of the gear. In another modification, the gear and pinion may both be cut simultaneously on both sides with rectilinear longitudinal feed of the cutter along the teeth. The invention may also be applied to the cutting of spur and helical gears. In the latter case, the feed of the finishing blades is along the helical teeth.

Filed: 1975-03-20
Abstract: 1467764 Inspecting cigarette ends AMF Inc 20 March 1975 [22 March 1974] 11684/75 Heading G1A The invention relates to a method and apparatus for the optical inspection of cigarette ends F, T for detecting defective cigarette ends. The method comprises feeding the cigarette to be inspected between two illuminating means, e.g. by fibres within bunches 301, 302 of optical fibres, simultaneously illuminating the ends F,T of the cigarette, detecting the reflected light from the cigarette ends e.g. by other fibres within bunches 301, 302, summing processed signals from the reflected light detectors, and comparing the summed signal with a reference signal, the arrangement being such that, should the summed and reference signals differ a cigarette reject signal is produced. Instead of detecting the reflected beams individually the reflected beam from one end of the cigarette may be used to illuminate or to supplement the illumination of the other end of the cigarette thus producing a "summation" of the reflected beams optically, Fig. 2 (not shown).

Abstract: 803,613. Semi-conductor devices &c. STANDARD TELEPHONES & CABLES, Ltd. April 22, 1955, No. 11698/55. Class 37. [Also in Group XL (c)] An electric bi-stable circuit comprises two semi-conductor devices each having an emitter, a collector and a control electrode which also operates as a collector. The device as shown in Fig. 1 comprises a disc 44 of N-type germanium having an annular emitter electrode 45, a whisker collector electrode 46 associated with N-P-N junctions and a whisker control electrode 47 associated with a PN junction. The device is enclosed in a tube 48 connected to the emitter electrodes. The whisker electrodes may consist of platinum with 10 per cent ruthenium and may comprise phosphorous or arsenic and be electroformed 'as described in Specification 747,198. Curve 50 in Fig. 3 shows the characteristic of collector 46 when 47 is unbiased, and curve 51 the characteristic when 47 is also biased negatively so that it collects a proportion of the available holes. If a circuit is used such that load line 52 lies between the two turnover points V1 and V3, the arrangement has two stable states. A negative pulse to collector 46, for example, would drive the operating point from the low-current condition 53 to the high-current condition 54. Alternatively, keeping collector 46 constant, the application of a positive pulse to control electrode 47 to render this less negative will also trigger the device from the low current to the high current condition. Fig. 4 shows two such devices 55A, 55B connected to form a bi-stable circuit, in which in each of the two conditions one of the devices is conducting and the other non-conducting. The collectors 46A and 46 B are interconnected by a capacitor 56, and the control electrodes 47A and 47B are connected through resistors to the input electrode 62. If device 55A is assumed OFF, and 55B ON, then a short positive pulse at terminal 62 will switch 55A ON, which drives collector 46B less negative or even positive, which switches 55B OFF. A second positive input pulse will restore the circuit to the initial condition. Specifications 686,958 and 708,899 also are referred to.
