Title: An arrangement for the control of converters which feed alternating-current machines
IPC: H02P27/04
Filed: 1963-05-03
Abstract: 1,042,322. Automatic speed control. LICENTIA PATENT-VERWALTUNGS G. m. b. H. May 3, 1963 [May 3, 1962], No. 17603 /63. Addition to 100, 896. Heading G3R. [Also in Division H2] The induction motor control system of the parent Specification is modified in that the control signals for the three phase, cross-connected or anti-parallel valve or semi-conductor converters are now produced by static circuits. A self-oscillating circuit loop comprises integrators 11, 21 and multipliers 12, 22, e.g. Hall plate devices. Two phase outputs at 90 degrees can be taken from 11 and 21 of amplitude largely independent of frequency, or from 12, 22 of amplitude proportional to frequency. It is shown that frequency and phase sense depends on a magnitude and direction of the D.C. signal from tachogenerator 1. The two phase output is converted to three phase, either by a transformer (Fig. 3, not shown) or by a multiplying and adding network (Figs. 4... 6, not shown). The three phase signals appear on three pairs of terminals each symmetrical with respect to earth, so that a six phase effect is obtained.

Abstract: 1,100,550. Controlling aircraft. DORNIER-WERKE G.m.b.H. 22 April, 1966 [9 June, 1965], No. 17705/66. Heading B7G. A V.T.O.L. aircraft control column comprises a shaft parallel to the aircraft longitudinal axis, and movable axially to control the direction of engine thrust, and rotatable about its axis to control the magnitude of the thrust. As described, the aircraft has a single engine with four rotatable nozzles 5-8. Axial movement of the shaft 35 is transmitted through control rods 33, 31, servomotor 32 and rack-and-pinion and bevel gearing 30, 26, 27 to rotate the nozzles, and rotary movement of the shaft is transmitted through a rotary member 55 splined to the shaft 35 so that it does not slide axially with the latter, and through control rods 38 and a servomotor 40 to an engine fuel control 4. Alternatively electric control transmission can be used. The shaft 35 is biased to a central position, axially and rotationally, by springs, and has a handle extending at right-angles to it which is horizontal in the central position. The control is arranged so that forward movement of the shaft produces forward movement of the aircraft, and upward movement of the handle increases the thrust. The invention is also applicable to aircraft with pivotable airscrews and pivotable jet engines.

Abstract: 515,897. Making shuttlecocks. FJELOTRUP, E. June 14, 1938, No. 17723. Convention date, June 15, 1937. [Class 132 (iii)] In a machine for applying the feathers to the head of a shuttlecock, the previously drilled head H, Fig. 2, is supported in an axially rotatable holder 13, Figs. 2, 3 and 4, adjacent to a table 52 on which the feather to be inserted is disposed with its shaft between gripper jaws 32, 33. The machine is released by clutching a cam shaft 5 to a constantly rotating shaft 4 for a single revolution. At the beginning of the operation the support 13 is rocked about a shaft 8 from a raised position to that shown, by means of a spring 27 under the control of a cam 26, Fig. 4. and follower 25. The pivoted left-hand gripper jaw 33 is now released by a cam-actuated roller 45 ' to the action of a' spring, whereupon it closes on the fixed right-hand jaw to grip the feather shaft. The jaws are carried by a slide 34 and are moved to the left (as shown in Fig. 2) to enter the feather shaft in the lowermost hole drilled-in the head H whereupon the jaws open to release the feather. The head now rises to remove the feather from between the jaws and is rotated by a cam-actuated pawl 16, co-operating with a ratchet 14, to present the next hole in the head to receive a feather. The above operation is repeated until a feather has-been inserted in each hole, after which the shuttlecock is ejected from the holder by a headed spindle 28 actuated by a hand lever 29. Another head is now positioned in the support by means of a tool, Fig. 5, comprising a sleeve 60 to fit over a.pin 15 extending over the support, the sleeve carrying an arcuate guide 57 to receive the head and a pin 58 to enter one of the holes therein. The angles of the feather shafts to the head may be varied in many ways by adjusting four supporting screws 61, Fig. 3, for the table, by rotating the gripper slide about a vertical axis and by changing the angle of elevation of the support 13.

Title: Motor stop control system
IPC: H02P3/10
Filed: 1971-05-28
Abstract: 1317673 Control of D.C. motors INTERNATIONAL BUSINESS MACHINES CORP 28 May 1971 [22 June 1970] 17801/71 Heading H2J In order that a member e.g. a carriage for a selective printer, may be brought to rest in a specified distance irrespective of variations in the deceleration characteristic of its driving motor the motor is first braked until its speed has dropped to a predetermined value, is then allowed to "coast" for an automatically varied time and finally is braked again to standstill. When the carriage is a predetermined distance from a desired stopping point a stop signal is applied to a logic circuit (Fig. 3, not shown) which immediately initiates reverse energization of the motor (which is a D.C. printed circuit machine) and also starts a fixed time "reference single shot". A speed detector connected across a resistor (31) in series with the motor produces a signal when the speed has dropped to half its initial value. This terminates braking and also starts a "proportional single shot" device comprising a capacitor which charges until a second signal is applied when the reference single shot times out, whereupon the capacitor discharges at a fixed rate, e.g. at the same rate at which it was charged, and produces a signal to re-start braking when fully discharged. Thus, if deceleration is more rapid than normal, due to the motor being cold for example, the motor coasts for a longer period at half speed as shown in Fig. 5. In an alternative arrangement of the logic circuit (Fig. 6, not shown) account is taken of the possibility of the reference single shot timing out before half speed is reached. In this embodiment the motor is driven by pulses from an oscillator (32) applied through a variable duty cycle device (34). The initial braking is by continuous current and the second stage by pulses.

Abstract: <PICT:0741848/III/1> In a plant for continuously dissolving out fatty substances from materials containing them, such as oilseeds, fabrics and leather, by means of solvents, all the appliances are enclosed in a chamber which communicates with the outside only through a pair of slits through which an endless belt is led in and out, on which the material to be treated is conveyed or which itself comprises the material to be treated, the belt passing through a number of solvent troughs and then through a drier separated by a partition from the solvent-treating compartment, and the plant including a blower arranged to feed into the drier and to create a slight vacuum in the chamber to decrease solvent losses through the slits.  The material to be treated may be held on the endless belt by another belt.  In a suitable plant, an endless belt B with the material C and a covering belt D passes into and out of a chamber E, enclosing all the plant, through slits 1 and 2.  In the chamber the belt passes through a number of solvent baths 3 each provided with guide rolls 4, a solvent sprayer 5 and a circulating pump 6 for supplying the preceding sprayer so that the solvent flows oppositely to the belt.  Squeezing rolls 8 are provided between the baths.  The fresh solvent is supplied from a tank 9, and the fattyladen solvent is removed from the first bath to a still 11, the fats being taken off at 16.  The solvent vapour from the still 11 is led to a condenser 14 and thence back to the tank 9.  The belt is then run through a drier 17 to remove the solvent, air heated in a heat-exchanger 20 being blown therethrough by a blower 18.  The solvent-laden air flows to a condenser 22 from which the condensate returns to tank 9, and the cooled air is sucked through pipe 24 by the blower 18.  The air can be completely freed of solvent by by-passing it through a pipe 25 to a scrubber 27 where it is sprayed with oil and leaves at 32.  In a modification the solvent-laden air is led to a set of three connected absorbers filled with silica gel and is passed through two of them to remove its solvent content, the third being meanwhile regenerated. The regeneration is effected by passing in superheated steam to drive off the solvent followed by superheated air to dry the silica gel.
