Abstract: 440,639. Drawing wire ; electric motor control systems. BARRON, C. A., Eldon Street Works, Preston, Lancashire. April 28, 1934, No. 12847. [Class 83 (iv)] [See also Group XXXVII] A wire-drawing machine has a separate variablespeed electric motor for driving the winding - up drum, means being provided to prevent this motor from starting until the main motor, which drives the drawing drums, has attained its running speed. The main motor is started by pressing a button m, resistance being automatically cut out by a series of rotor contactors until full running speed is reached. After an adjustable time interval, determined by a device in the last accelerating contactor of the main motor, the winding-up motor e is switched in and at the same time a pilot motor r is started which accelerates the motor e by movement of its brush gear, whereupon the pilot motor is automatically switched out. On stopping the motor e, the brushes return to the low speed position. Series contacts for manually stopping and starting the motor e are controlled by buttons m<2>, m<3>. Both motors are stopped by a switch m<1>, and the motor e is speeded up and slowed down by switches m<4>, m<5> respectively. Brake shoes g are held away from a brake drum f while the motor e is running, by energization of a solenoid p, but engage the drum to bring the winding-up drum a quickly to rest when the motor e is switched off, and the solenoid p is de-energized. According to the Provisional Specification, a light indicates when the main motor has attained its full speed.

IPC: B03C5/00
Filed: 1966-03-23
Abstract: 1,186,184. Dialysis in annular chamber; centrifugal liquid-contact apparatus. NATIONAL RESEARCH DEVELOPMENT CORP. 14 March. 1967 [23 March, 19661, No. 12875/66. Headings B1F and BIX. [Also in Division C7] Material dissolved or dispersed in a supporting fluid is separated from the supporting fluid and/or separated into fractions by subjecting it to a force field while passing it through a substantially uninterrupted annular chamber having an outer wall which is rotated relatively to a coaxial inner wall to stabilise flow conditions. The inner wall may be stationary or rotate in the same direction as the outer wall but slower. The separation may be in an electric field (electrophoresis) (see Division C7), magnetic field (magnetophoresis), centrifugal and/or gravitational field (sedimentation), or in a chemical field (diffusion, or dialysis if a membrane is used to magnify the ratio of diffusion constants, partition if two incompletely miscible solvent fluids are concerned; or absorption if there is adherence to a solid surface). The material to be separated may comprise atoms, molecules, particles, droplets, bubbles or biological cells. The supporting fluid may be liquid or gaseous. In the apparatus of Fig. 5, the force field is centrifugal whilst in that of Fig. 6 it is based on partition between two solvents. Each Fig. is a diagram of a section through an annular chamber, only the left hand side of the section being shown. In each apparatus the outer wall rotates relatively to the inner wall. In the apparatus illustrated in Fig. 5 there is centrifugal separation as fluid which contains material to be separated (called the migrant) flows upwardly through the apparatus. Different fractions are collected at different levels where the fluid leaves the apparatus. The taper of the inner wall causes fluid to circulate against that wall as indicated by arrows. In the apparatus illustrated in Fig. 6 a concentrated solution of migrant in a first solvent A is fed in slowly at 901 while a faster stream of solvent A is fed in, in the same direction, at 903 and extracted at 905. A second and heavier solvent B is fed in, in the opposite direction to solvent A, at 907 and is extracted at 909. Migrant components having partition coefficients above or below a critical value emerge at 905 or 909 respectively. The critical value may be altered by varying the relative rates of flow of the solvents.

Abstract: 202,027. Potter, H. S., and M-L Magneto Syndicate, Ltd. May 10, 1922. Magnetos, driving; enveloping in special media.-In an electric light outfit comprising a magneto-electric generator 13 driven by a compressed air turbine wheel 16 and supplying current to an electric lamp 19, the compressed air plays directly on the turbine-wheel blades 17 through a nozzle located in the casing of the generator and turbine wheel and adapted to be connected to a compressed-air supply. The generator is of the inductor or of the revolving magnet type having fixed windings 18, the magnets 13 being of cobalt steel. The speed of the motor may be controlled by a centrifugal governor or brake. In the arrangement shown in the Figure, balls 46 in flying outwardly move the disc 37 against the spring 40, so as to close partially the exhaust port 36 and so control the speed. The lamp 19 is enclosed in a glass cap or bowl 27 secured in an air-tight manner by a flange 28 to the end wall of the casing, and communicating by means of a passage 31 with the turbine chamber. In order to short-circuit the armature windings and so extinguish the lamp 19 should the bowl 27 be broken, two contacts 34, 35 are provided. The contact 34 is carried by a diaphragm 33 enclosing a space 32 communicating with the atmosphere. The contact 35 is fixed, and as long as the air pressure within the bulb is above atmospheric pressure the contacts 34, 35 are kept apart. Should the bowl 27 be broken, the pressures on the two sides of the diaphragm 33 will be equalized, so that the contacts 34, 35 come together and short-circuit the armature windings 18. The part of the casing enclosing the generator may be made air-tight, may be filled with an inert gas such as carbonicacid gas, and may be provided with a screen of gauze. The carbonic-acid gas may be supplied to the casing by means of capsules. For this purpose a hollow socket is provided in the casing fitted with the usual pin for perforating the end of the capsule. The casing may be provided with a stirrup member whereby the lamp may be suspended. The lighting set is particularly suitable, for use in mines and inside boilers, tanks, and double-bottoms of ships.

Abstract: 1323666 Coin-operated telephone systems SIEMENS AG 5 May 1971 [6 May 1970] 13270/71 Heading H4K An S.T.D. call dialled from a paystation is charged by coin collection in response to meter pulses occurring at the zone metering rate appropriate to the call but of a value which does not correspond to coin values, the meter pulses being formed into cycles for coin collection, pulses of each cycle collecting more units of coin value than are due throughout the cycle except for the end of the cycle where at least the last pulse collects less than is due for its period so that the charge collected over each cycle as a whole is the due charge, a meter pulse which finds no further credit at the paystation causing release but only after the allowance of extra time equal in value to the extent of overcharging, if any, up to that point of the charging cycle. Fig. 1 shows a circuit which measures out the periods of extra time allowed in respect of overcharging. A capacitor C1 is initially charged for the period between two meter pulses to provide a voltage for comparator Vg in proportion to the particular zone meter rate for the call. The cycle of meter pulses is stepped out by a relay chain K1 to Kn (not shown) contacts of which successively prepare charging circuits for a capacitor C2 and each of a rate fast or slow according to the smaller or lesser extent of overcharging effected by each pulse. When capacitor C2 charges up to the level of C1, in response to relay TR operated to a pulse which finds no more credit, release relay V is operated by Vg. As the last pulse of a cycle calls for no adjustment, its contacts kn cause immediate release and discharge of the capacitors C1 and C2, should credit be exhausted by such a pulse. To avoid leakage effects, C1 may be reset and discharged at the beginning and end of each charging pulse cycle; the dotted line connections of Fig. 1 show a way of doing this. The particular ease considered is a charging rate of 18 Pfg per pulse levied by coin collection of 20 Pfg for each of four meter pulses followed by 10 Pfg for the fifth pulse of each cycle of five such pulses.
