Abstract: 761,943. Wire &c. cores, covering. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Aug. 29, 1955 [Sept. 2, 1954], No. 25448/54. Class 109. [Also in Group XXXVI] A paper covering is formed about a P.V.C. insulated conductor 15 by applying adhesive to one face of a paper strip 22, forming the strip longitudinally into a tube about the conductor with the adhesive-coated face innermost, pressing the paper on to the conductor and passing it through a heated chamber 14 to dry the adhesive. The paper strip is drawn from a roll 23, over a roller 11 which collects adhesive from bath 10, and into a circumferential channel on pulley 18. The insulated conductor 15 is drawn through a grooved portion of the channel so that the treated face of the paper comes into contact with and adheres to the exposed portion of the insulated conductor. The paper is folded around the insulated conductor by forming dies 12, 13, and the covered wire passes through a drying tube 14 to a take-up drum 21. The paper may be rendered non-hygroscopic by a further coating of lacquer and dried before reeling.

Abstract: 1,078,529. Frequency meters. GENERAL MOTORS CORPORATION. June 17, 1965 [July 23, 1964], No. 25622/65. Heading G1Q. A frequency meter has a permanent magnet armature (not shown) which aligns itself with the resultant field of three fixed coils 24, 26, 28 of which coils 24 and 26 produce frequency dependent fields at an angle to each other and coil 28 produces a field independent of frequency but opposed to the field of coil 24. The frequency dependence may be ensured by a capacitor 34 and the system used as a vehicle tachometer in which the output of an alternator generator driven by the vehicle engine produces a pulse train, as shown, whose frequency is proportional to vehicle speed. Fig. 2 (not shown) depicts the meter construction. Coils 24 and 28 are wound on a common former and coil 26 lies inside this with its axis perpendicular to that of the other coils. The armature is a diametrically magnetized disc mounted on an axle which is perpendicular to the axes of the coils and which carries a pointer at one end.

Filed: 1935-09-16
Abstract: 463,044. Moulding battery electrodes. SCHIDLO, 0., and PILE LUMINA BELGE SOC. ANON. Sept. 16, 1935, No. 25670. [Class 87 (ii)] [Also in Group XXXVI] An electrode comprising a conductor surrounded by a depolarizer is made by forcing the conductor while in a plastic condition into an opening in the depolarizer. The conductor may consist of a mixture of graphite, lampblack or other form of powdered carbon with paraffin oil. The electrode is made in a machine which moulds the depolarizer and the plastic conductor and connects the two together. A device may also be provided for embedding a contact wire in the conductor during the moulding process. Fig. 2 shows the part of the machine for moulding the conductor and embedding the contact wire therein. A mixture of graphite and oil is placed in a mixer 4 from which it is expelled by a screw 5 into a chamber 6 from which it is forced into a mould 34 by a piston 7. Heating and cooling devices 14, 15 are provided. The wire 11 for forming the contact is supplied from a drum 12 and passes through a device 40 which causes only a predetermined length of wire to be supplied at a time. The wire passes through a nozzle 10 and is drawn centrally into the mould 34 by the moving plastic material and the wire and plastic material are cut simultaneously by a shear 13. The lengths of moulded material with the embedded wires pass out of the mould and fall down an inclined channel 18 where they are arrested by a stop 20 and cut to the required length by a shear 21. The stop 20 then frees the rod of plastic material which slides down a channel 22 into a slide 41 and is ready to be forced into the opening of the depolarizing mass which is made from material taken from a container and compressed in a mould 23 round a core 27, the pressure being obtained by a hollow member 26 as shown in Fig. 4. The end of the core 27 is provided with a passage 32 to receive the projecting end of the wire 11 embedded in the plastic material forming the central conductor. The latter is forced into the central opening of the depolarizing mass by a ram 31, Fig. 2, the core 27 receding at the same time as shown in Fig. 6. Fig. 1 shows the finished electrode comprising the projecting contact wire 3, central plastic conductor 2 and depolarizer 1.

In an automatic control system for the electrode of a metal working machine in which the removal of metallic material is effected by the erosive action of an electric spark, the spark voltage and a reference voltage are applied to a polarised relay which energises a reversible electro-mechanical transmission between an electric motor and the electrode. In one embodiment, the relay 16, energised by the voltage of the electrode 1 and a reference voltage tapped off a potentiometer 17, selectively energises electromagnetic clutches 8, 9 to drive pinion 13 and rod 3 from one or other of the oppositely rotating gears 6, 7, driven by the motor 4. The electrode may be retracted faster than it is advanced by means of unequal gear ratios. For A.C. discharges, a rectifier is inserted in the relay coil circuit. In a second embodiment, Fig. 2 (not shown), the electrode is actuated by a screw-jack, rotatable in either direction by a motor which is movable between a pair of drive discs so that a friction wheel on the motor engages the face of one or other disc. The motor is moved by a pair of solenoids selectively energised by the polarised relay.
