Title: Improvements in and relating to machine tools
IPC: B23Q35/18
Filed: 1931-10-15
Abstract: 395,682. Driving, turning, and planing machines; copying and reproducing mechanism. MANNESMANNRÍHREN. WERKE, 1B, Berger Ufer, D³sseldorf, Germany. Oct. 15, 1931, No. 28684. Convention date, Dec. 15, 1930. Void [Published under Sect. 91 of the Acts]. [Class 83 (iii).] In a metal-cutting machine employing a tool similar to a turning tool, the tool is set to its required position or moved in conformity with a desired pattern by means of a servo-motor. As applied to a planing-machine, the vertically adjustable slide 4, Fig. 2, carrying the tool-box 5 is moved by screws 3 driven from an electric motor 1. A reversing switch for the motor comprises contact blades 7, movable by a screw 6 operated by hand in conjunction with a fixed scale 8, and blades 10 movable by a screw 11 driven from the motor 1. In operation, the part 7 of the switch is set to a desired point on the scale 8, whereupon the motor 1 is started and the slide 4 is moved to a corresponding position on the vertical pillars of the machine. On attaining the position the part 10 of the switch is moved by the screw 11 to open the switch and thus stop the tool in the exact required position. As applied to a copying- lathe, the tool 13, Fig. 4, is carried by a transverse slide 14 mounted on a longitudinal slide 15. The screw 24 for the slide 14 carries a pinion 23 engaging a rack 22 mounted on the pistonrod 21 of a hydraulic cylinder 20 attached to the slide 15. A control valve 27 for the cylinder is connected thereto by flexible pipes 25 and has its reciprocating valve connected by the linkage shown to a roller 30 co-operating with a fixed template 31 and also to a link 29 on the piston-rod 21. In operation, as the slide 15 is traversed slowly along the rotating work 12 the roller 30 moves along the template 31 and thereby displaces the valve 27 from its mean position and causes a corresponding movement of the tool, the link 29 tending constantly to restore the valve to the mean position and consequently giving the tool a path similar to that of the roller 30. The scale of the work may be made to bear any desired relation to that of the template by varying the linkage connected to the valve 27 and the pitch of the screw 24.

IPC: C08L61/10
Filed: 1964-09-17
Abstract: Moulding powders for insulating materials are made by mixing novolac resin, hardener, lubricant, filler, colouring material and anhydroformaldehyde aniline and/or furfurylidene aniline and then milling the mixture and reducing it to powder.  Procedures wherein the anhydroformaldehyde aniline is preliminarily mixed with the novolac are disclaimed and the disclosure in Specification 621,044 is acknowledged. In the examples, the hardening agent is paraformaldehyde or urotropine and MgO; the lubricant stearine or calcium stearate; the colouring agent is clay dyed with ferrous oxides; and the fillers are kaolin, wood flour straight or soaked with an alkali-condensed phenol-formaldehyde condensate and kaolin. It is stated that processes using N,N1-di-(oxazolidyl-3)-diphenyl methane instead of the aniline compound are known.

IPC: G01R11/36
Filed: 1927-11-04
Abstract: 281,250. British Thomson-Houston Co., Ltd., (Assignees of kinnard, I. F.). Nov. 29, 1926, [Convention date], Alternating-current induction machines. - In an induction disc motor, the magnetic circuit is so proportioned as to operate with varying applied voltage over a selected flux-density range below saturation where its permeability changes in such a way that the ratio of applied voltage to operating flux varies in a predetermined manner. Fig. 2 shows the driving-magnet of an induction motor meter in which the damping action of the potential flux is corrected for by making the potential flux cutting the disc vary at a rate greater than the first power of the total potential flux. The inwardly projecting arms 17 of the potential magnet are so proportioned that they normally operate on the decreasing permeability part of the curve, such as the point C, Fig. 3, corresponding to a flux density of about 9 kilogausses. The other branch circuit of the potential flux, namely the arms 18, are proportioned so that they normaly operate on the increasing permeability part of the curve, such as the point C<1>, corresponding to a flux density of about 1 kilogauss. On an increase in voltage, the flux density through the parts 17 increases to the point D and that through the parts 18 to the point D', so that the path 17 decreases in permeability and the path 18 increases in permeability a greater proportion of the total flux therefore passing across the main airgap and a smaller proportion through the shunt path 17. The magnetic paths are so proportioned that this increase causes the increase in net torque to be proportional to the increase in voltage. In a modification the parts 18 are omitted and the parts 17 are operated at the point F on the permeability curve. The ratio of the potential flux to the current flux is made considerably greater than usual so as to minimize the damping effect of the current flux on overload.

Abstract: 629,834. Magnetic race games. JOYCE, J. A. Nov. 5, 1947, No. 29547. [Class 132 (ii)] Models 6, 7 are traversed round closed circuits 4, 5 by magnets 9, 10 carried on a common table 11 fixed to a sleeve 12 rotated by clockwork 16, the magnets 9, 10 being moved relatively so as to vary the position of the models. The models each carry a vertical magnet or a piece of magnetisable material. The magnets 9, 10 are mounted in slots in the table 11 and mount by lost motion devices rods 21, 22 the other ends of which are pivoted eccentrically by lost motion devices to wheels 24, 25, the former being in engagement with a tyre 28 on a fixed axis 13. Thus the magnets are moved in their slots as the sun-wheels 24, 25 move around the tyre 28 with the table 11. To make a race result more unpredictable the circumference of wheel 24 is not an integral multiple of the circumference of the tyre 28. According to the Provisional Specification, a starting pen and gate may be provided, an electric motor may drive the apparatus and the relative position of the magnets may be varied by cams or cranks co-operating with a rail on the underside of the track through rollers.

A distributer for powdery material comprises a hopper, the lower end of which opens into an annulus 93 which bears upon the central region of the upper surface of a spreading member 92. The annulus 93 is formed with three outlet ports 96, 97, 98 and to control the flow of material through the ports, masking plates 119,, 120, 121 are used which are fixed to a cylindrical ring 117. The annulus 93 is adjusted by means of an arm 106 connected to the annulus by a rod 105 which co-operates with a member 91 and is secured thereto by a resilient pin which may be inserted in any hole 110. The ring 117 is provided with an arm 124 on which is mounted the scale 125 which co-operates with a member 154 to indicate the position of the masking plates relative to the outlet ports. An adjustable stop 126 is used to set the required position of the masking plates and normally the stop 126 abuts against the stop 154. When turning at the end of a field it is necessary to close the outlet ports by means of the masking plates and a pin 164 on arm 106 co-operates with a member 163 fixed by means of a spring 131 to the arm 124. As shown, the pin 164 engages the member 163 to close the outlet ports. To open them a cable 137 is pulled which releases the pin 164 from the member 163 allowing the annulus 93 and ring 117 to rotate under the action of a spring 129 until the stop 126 contacts the fixed stop 154. Specification 1,000,873 is referred to.
