Abstract: 1,225,475. Control of D.C. motors. G. M. PFAFF A.G. 2 May, 1969 [1 June, 1968] No. 22481/69. Heading H2J. [Also in Division G3] In a motor speed-control system involving a semi-conductor controlled rectifier 5 fired by a unijunction transistor 25 the firing point is controlled by the charging of a capacitor 28 in a resistance-capacitance network whose time constant is dependent upon the back e.m.f. of the motor armature. A series motor 8 is connected in series with the S.C.R. 5 across the output of a bridge rectifier 2, the gate of the S.C.R. being connected to the secondary of a pulse transformer 23. The primary of the transformer is in series with the unijunction transistor 25 supplied from a tapping of a potential divider 16-20 supplied with pulsating D.C. from the rectifier 2. The emitter E of the unijunction 25 is connected to a capacitor 28 charged through a variable speed-setting resistance 31 from a reference voltage 19 provided by a Zener diode 20. Across the capacitor 28 is a transistor 33 which thus shunts part of the charging current through resistance 31 and controls the time constant according to the voltage at the base of the transistor which is the difference between the reference voltage and the motor armature voltage, the latter being derived either across the whole motor, as shown, or across the armature only. In operation variation of the back e.m.f. varies the conduction of transistor 33 and therefore the charging rate of the capacitor 28 and thus adjusts the point at which the S.C.R. is fired in each half-cycle of the supply. Furthermore, since the unijunction 25 is connected to the unstabilized rectified supply, variations in supply will also vary the point at which the unijunction and therefore the S.C.R. fire. Diodes 12, 13 remove the inductive voltages produced when the motor current is interrupted; an R.C. network 14, 15 removes high frequency interference.

Abstract: 1,232,605. Measuring pressure electrically. WALLACE & TIERNAN Inc. Sept.30, 1968 [Oct.2, 1967], No.46331/68. Heading G1N. [Also Division H1] An electro-mechanical servosystem used for indication of pressure supplied to capsule 46 comprises a linear variable differential transformer having primary windings 22 enclosed in two cup shaped members 10 and 11 (of magnetic material) mounted on a plate 17<SP>1</SP> which can be shifted sideways within limits by the action cam follower 56 actuated by a cam 57 which moves along a threaded shaft 67 which is rotatable in either direction through gears 74, 75 driven by a reversible motor 77. Changes of pressure in the capsule result in communication of movement to the secondary coil 29 of the transformer through the rod 321 producing a secondary emf which is fed to a servoamplifier 83 whereby the output is fed back to the motor which sets the cam 57 in action to move the plate 17<SP>1</SP> sideways and so the primary coil assembly, till the original null position of the primary and secondary windings is achieved. The motor shaft in the meanwhile actuates a counter 78 the reading of which is indicative of the extent of pressure variation in the aneroid capsule. The transducer of the invention can also be used in combination with an aneroid differential capsule comprising housings 88 and 92, Fig. 7. The secondary coil in this case is in a hermetically closed housing 91 made of a non-magnetic material with high electrical resistivity to reduce effects of the housing on the phase and amplitude of the secondary voltage.

Abstract: 1,233,862. Making electrical coils. FORD MOTOR CO. Ltd. 13 Jan., 1970 [5 Feb., 1969], No. 1503/70. Heading B3A. [Also in Divisions B8 and H2] Apparatus for wrapping a sheet of insulating material, e.g. crepe paper, around a copper electrical conductor and winding the conductor to form coils comprises: an adhesive applicator 52 for coating one side of insulating material 20 with adhesive; a supply and cutting drum 56 for feeding required lengths of the insulating material into engagement with the copper conductor 18; a series of shaped rollers 82-90 for folding the insulating material around the conductor; a die 60 for cutting the conductor into required lengths; and a mandrel 62 around which the conductor is wound. The insulating material 20 is cut into lengths slightly shorter than the conductor so as to leave the ends of each coil free of insulation. The supply and cutting drum 56 is shown partially in section in Fig. 10 and has a groove 68 in its outer surface in which the crepe paper 20 is held by maintaining a vacuum in cavity 66, the cavity communicating with the groove through passages 70, 72. A serrated cutting edge (Figs. 11, 12, not shown) projects into the groove at one point around the circumference of the drum for cutting the crepe paper into required lengths. In operation, at the beginning of a cycle a roller 80, Fig. 9, is moved upwards by a cam 74 to bring the conductor 18 into contact with the adhesive-coated surface of the crepe paper supplied, flat, from drum 56. The conductor and paper are then passed between a series of pairs of rollers (Figs. 13-18, not shown) which fold the paper around the conductor. When sufficient paper for one coil has been drawn from drum 56, corresponding to one revolution of the drum, the drum is stopped whilst the conductor continues to move a further short distance, thus tearing the crepe paper at the position of the serrated cutting edge, whilst also ensuring that the end portions of the conductor are free of insulation, to form the ends of a coil. A cutting die 60 then cuts the conductor and shapes the end (14, Fig. 1, not shown). The coil, as formed on the mandrel 62, is flat, but is subsequently pressed into an arcuate form (Fig. 7, not shown).

Abstract: 1,252,490. Semi-conductor devices. GLOBEUNION Inc. 14 Aug., 1969 [27 Jan., 1969], No. 40611/69. Heading H1K. [Also in Division C7] An ohmic contact 12 on a semi-conductor element 10 consists of a hypoeutectic alloy of Ni and In; i.e. an alloy containing less In than is contained in the eutectic Ni/In alloy. The preferred In content of the contact 12 is 5-20% by weight. The device shown comprises a junction capacitor including a ceramic body 10 of barium titanate formed by pelletizing powdered material, firing in an oxidizing atmosphere at 2400‹ F. and heating at 1700-2300‹ F. in a reducing atmosphere to render it semi-conductive. Other semi-conductor materials mentioned are MnO, Fe 2 O 3 , Ga 2 O, NiO, Cu 2 O, TiO 2 , ZnFe 2 O 4 , SrTiO 3 , calcium or lead titanates and barium, magnesium or lead zirconates. The material may be intrinsic, N-type or P-type, and suitable dopants are La, Bi, B, In or Sb. The Ni and In for the ohmic contact 12 may be applied simultaneously or sequentially, the latter process being followed by firing to cause inter-diffusion. Vacuum deposition may be employed, or a Ni/In alloy may be ground, deposited as a powder and fired. The preferred process entails applying to the body 10 a mixture of finely divided reducible compounds of Ni and In; e.g. oxides, carbonates or resinates; in powder form or preferably dispersed in a matrix consisting of a film-forming vehicle, such as ethyl cellulose resin, and a slow-drying aromatic solvent, such as high b.pt. xylene. The mixture is painted or sprayed on and dried at 250-300‹ F. It is then fired at 1660-2000‹ F. in a reducing atmosphere to reduce the Ni and In compounds to elemental form. This process may be combined with the reduction of the ceramic body 10. The junction of the device is formed by applying a layer 16 of finely divided Ag in an inorganic binder of borosilicate frit and Bi 2 O 3 . On firing at 1700‹ F. it is considered that Bi diffuses into the body 10 to form a barrier layer 18. A further layer 14 of Bifree Ag may be formed on the ohmic contact 12 by applying an Ag or Ag 2 O dispersion in an organic resinous vehicle and firing.
