Title: Method of manufacturing scouring pads
IPC: A47L13/07
Filed: 1948-04-19
Abstract: 642,051. Making scouring-pads. GEFELDT, R. W. April 19, 1948, No. 10793. Convention date, April 22, 1947. [Class 83 (ii)] [Also in Group VI] A method of manufacturing a pad for scouring kitchen utensils from a length of tubular knitted metal wire 1 having a flattened crosssection comprises rolling both ends of the fabric upon themselves towards the central portion 5 of the length of the fabric to form two annular rolls 2 of substantially equal size joined by a short intermediate portion of the fabric, and winding a metal wire 3 around the intermediate portion so as to contract it to a lesser diameter than that of the annular rolls and so draw the rolls towards one another. The metal wire is passed between rollers to flatten its crosssection before being machine knitted into tubular form. On cutting the knitted tube to correct length, the tension in the knitted wire acts to roll back the ends as viewed in Fig. 1. Axial pressure applied to the annulus serves to roll back the ends to the required diameter, shown in Fig. 3. The central part 5 is then reduced in diameter by the wire 3 to such an extent as to prevent the user's finger from passing therethrough. Several scouring pads may be threaded on to a mandrel where they may be compressed. The wire 3 may be wound around the knitted fabric and tightened by means of a machine.

Title: Excess voltage arrester with quenched spark gap and voltage-dependent resistances with increased protection quality
IPC: H02H9/06
Filed: 1956-04-13
Abstract: 827,294. Protective arrangements. LICENTIA PATENT - VERWALTUNGS G.m.b.H. April 13, 1956 [April 14, 1955], No. 11301/56. Class 38 (4). A device for the protection of electrical installations and apparatus against excessive voltage surges consists of two or more voltage diverters, Fig. 2, connected in parallel, and grouped in close proximity, so that the arc discharge of one diverter ionizes the spark gaps 12 of the other diverters in the group, causing these to operate also. The diverters each consist of a voltage dependent resistor 6 in series with a number of electrodes 8 interleaved with insulating spacers 9. The characteristics of each diverter in any one group may be the same as, or different from, the others in the same group, and, in addition, may be designed so that the operating voltage due to a surge or other H.F. transient is lower than the corresponding operating voltage at power frequencies. The spacing between each pair of diverters in a group must be increased with system voltage to avoid excessive voltage stress between a diverter which has operated, and one that has not. This spacing may be reduced by designing each group for a limited voltage range, and connecting two or more groups in series between the supply and earth. One of the diverters may be arranged to have a lower stacking voltage than the others to pre-ionize the spark-gap to minimize the stacking time of the arrester.

Filed: 1943-07-17
Abstract: 566,991. Forging-machines ; chucks. NEWALL, A. P. July 17, 1943, Nos. 11651 and 12489. [Classes 83 (ii), 83 (iii) and 83 (iv)] A bar swaging-machine has a carriage for holding the bar and feeding it through the dies, movement of the carriage controlling the dies to render them alternately operative and inoperative and at the same time the speed of traverse is regulated to produce a rapid movement whilst the dies are idle. A shaft 13 rotatable in roller bearings 14 in the frame 11 has a head 12 in which opposed dies 16 slide under the action of slide blocks 19<1> fitted with rollers 201 that contact with rollers 17 mounted in a cage 18. Wedges 21<1>, interposed between the slide blocks and the dies, are connected to a hollow spindle 22 connected for axial traverse, to a bell-crank 26 actuated by a hydraulic piston 24. Movement of the wedges renders the dies operative or idle. Standards 35 support ways comprising four channel bars 33, 34 between which a carriage 32 runs on wheels 46, 47. A hollow spindle 48 mounted in ball bearings 69 is tapered to swivel a bevel closing collet 50 advanced into the chuck, for clamping the end of the bar stock A, by a screwed sleeve 51. The spindle is formed at 53 and the sleeve 51 at 52 to receive tommy bars to impart the necessary relative rotation. The stock held in the chuck is free to rotate with the dies when gripped by them, but is braked from too free a rotation by a shoe 54 lined with friction material 55 and pressed against the flange 48<1> by springs 56. A handled arm 74 rotatably connected to a half-nut 65 moves over a cam surface to control the engagement of the nut with a lead screw 64 driven by a motor 66 through reduction gearing 67. 'A projection from one side of the carriage houses a sliding striker 61 that coacts with tappets 62, 63 adjusted along rods 30, 31 according to the lengths to be swaged and left unworked. The bars are connected by levers 29, 291, 29<11> pivoted at their. mid-points. The parts are shown in the swaging position in Fig. 1 and this continues till the striker 61 contacts the tappet 62 moving the bar 30 to the right. The rocking of the lever 29 actuates a relay valve 28<1> controlling a reversing valve 37 through a throttle control valve 38 to admit oil from a motor-driven pump unit below the piston 24 and withdraw the wedges 21<1>. At the same time an arm 69 of the lever 29<11> operates a switch to increase the speed of the motor 66 and consequently the rate of traverse of the carriage 32. In disengaging from the tappet 62 the striker moves into position to engage the next tappet 63, contact with which restores the parts to the initial condition. After a complete traverse of the carriage, the chuck is released, and the half-nut is raised, permitting the carriage to be returned to the left ready for a fresh traverse. Making bolts and studs.-Stock thus swaged may be cut into blanks for the manufacture of bolts or studs, the threads being preferably formed by die rolling.

[Also in Group XXVIII] A gas pump, withdrawing gas from a gas holder, has its power supply cut-off when the gas in the holder falls below a predetermined quantity, by means of a control device comprising a magnet 2 supporting a lower armature 3 connected to means such as a weighted lever 17 controlling the power supply, and an upper armature 4 connected to means responsive to the movement of the bell of the gas holder and which moves towards the magnet as the bell approaches its lowest point thereby causing the magnet to release the lower armature and hence the power supply to be cut off. The armature 3 is connected by links 8, 10 to a pair of claw members 11, 12 supported by links 13, 14 from a casing 1. The lever 17 is held upwards by the claw members and its weight provides a loading means for the lower armature. When the latter is released the claw members open to release the lever 17 which may be connected to a steam valve for a steam turbine driving the pump or to an electric switch when the pump is driven electrically. A compressing spring 5 between the two armatures facilitates the release of the lower armature. The control device may be reset automatically or manually. In another embodiment the lower armature is loaded by a weight on a separate lever from the lever 17. In another embodiment, Fig. 5, the compression spring is omitted and the lower armature 3 is loaded by a weight 26 and controls a butterfly valve 28. The upper armature 4 is operated through a weighted lever 34 and chain 33 by a differential drum 29 connected to the gas-holder bell. The lever 34 may be moved by hand to effect an emergency stop.
