Title: Improvements in textile spinning and twisting processes
IPC: D01H1/06
Filed: 1920-06-05
Abstract: 172,343. Binns, W., and Mander, J. D. June 5,1920. Spinning and twisting machines; spindle apparatus; spindledriving apparatus; twist tubes and like twisters; doffing arrangements; rollers and roller heads. -Unspun or partially spun and twisted sliver or yarn from a cop 1 is conducted by an air current through a tube 7 between drawing rollers 4, 5, 6 and thence through a tube 9, coaxial with and forming an extension of the tube 7 and rotating at from 20,000 to 60,000 revolutions per minute, from which it is projected by centrifugal force and is wound in the form of a hollow cop on the interior of a rotating and reciprocating cap 14. The yarn may be guided out of the axial path by a partition 8 in the guide-tube. A driving-wheel 12 is arranged to drive a number of tubes which arc preferably provided with double helical teeth. To doff the cop, a tube or spindle is inserted within the tube 9 and the cap 14 stopped or slowed down, whereupon the cop contracts on to the spindle or tube. This action may be assisted by a current of air introduced at the top of the cap or issuing from the top of the tube upon which the cop contracts. The tube 9 may be withdrawn upwardly from the cap 14 and a spindle 19, Fig. 2, inserted and clutched thereto, a cop tube 23 splined on the spindle being then raised into the cap and subsequently lowered when the cop has contracted thereon as previously described. In the Provisional Specification it is stated that the cop may be ejected by a spring-controlled follower or plunger.

Patent GB-609306-A (GB)
Title: Improvements in director or like control systems for guns
IPC: F41G3/14
Filed: 1942-11-10
Abstract: 609,306. Director control systems for guns. FLETCHER, G. H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Nov. 10, 1942, No. 15891. [Class 92 (ii)] A fire control system for a gun comprises a device adapted to respond to the relative angular positions of the gun and a director, or other controlling apparatus, the device serving to actuate means adapted to prevent firing when the angular displacement between the gun and director exceeds a predetermined value. In one construction, Fig. 1, the gun and director are mechanically connected to the rotors of selsyn devices 1, 2 respectively,'the stators of the latter being interconnected by conductors 6, 7, 8, and the windings 3, 10 of their rotors being arranged electrically at right angles when gun and director are in alignment. By such an arrangement no voltage is induced in winding 10 when alternating current from a source 4 is supplied to the rotor of device 1 and when the gun is aligned with the director. Under such conditions no current flows through a relay 11, a member of which then bridges a gap between two contacts 12 in the firing circuit. A similar relay 11a is also provided in conjunction with another selsyn device and contacts 12a, one system being associated with the training and the other for elevating movements of the gun. Thus, when alignment is effected and a switch 14 depressed, current from a source 13 energizes a solenoid 15 to effect firing. When misalignment occurs, current flows through relay 11 (or 11a) and breaks the firing circuit. Indicating lamps 16, 17 and cut-out switches are arranged in the circuit as shown. In a modification, Fig. 4, the firing circuit is substantially the same as that in Fig. 1. According to this construction the pointer 25 of an indicator follows, by means of a selsyn device, the movements of the director, while an index finger 40 is mechanically geared to the gun. The pointer and index finger form spark-gap electrodes associated with the secondary winding 45 of a transformer 44, the primary 46 of which is connected to relay 11 and to a power source 47. When parts 25 and 40 of the indicator are well out of alignment, no spark bridges the gap and insufficient current flows through relay 11 to cause it to close the gap between contacts 12. When sparking occurs, however, the gap is closed and the gun may be fired. Further modifications are described in which an indicator and transformer are employed. In another modification, means are employed in association with the selsyn devices for maintaining the gun in alignment with the director. Specifications 592,208, 609,294 and 609,297, [all in Group XXXVIII], are referred to.

Title: Improvements in water turbines
IPC: F03B1/00
Filed: 1961-05-02
Abstract: 938,967. Hydraulic turbines. GILBERT GILKES & GORDON Ltd., and E. A. JACKSON. May 2, 1961, No. 15893/61. Class 110 (3). The buckets of the runner of an axial flow impulse water turbine in which one or more jets are directed on to the runner at an angle with its plane of revolution have " master portions " situated towards the discharge edges in which sections of the working face taken in planes parallel to the inlet plane lie on involute curves with a base diameter approximately equal to the runner mean diameter (D), the distance travelled by the master involute, i.e. the involute at the entrance to the master portion in intersection with the involute construction line and the length of the master involute on any bucket or both being more than 0.75 of the full load jet diameter (J). The master portion also has an axial depth of 0.4 to 0.6 of the total bucket depth with D/J ratios of 4.0 to 3.5 or less and from 0.7 to 0.1 for D/J ratios of 12 to 10. In a modification, the involute curves are replaced by curves constructed so as to make a constant angle with a construction line drawn parallel with the jet axis as the curve is rotated about the runner axis. A jet of diameter J, Fig. 1, intersects the inlet plane O-O of an axial flow impulse turbine in an ellipse with centre P and major axis n-n 1 . The discharge portion q, t, u, v, w of the buckets of the turbine include a " master portion " r, s, u, v or F 1 , F 3 , F 6 , F 4 . Sections of the working face of the master portion taken parallel to the inlet plane lie on involutes which are constructed so that the section is perpendicular to a construction line f, f 1  parallel to and J D with - or - of the jet centre line XX so that 5 20 the involutes have a base diameter nearly equal to the runner mean diameter D. The " master involute " at section 6, 6 is at least 0.75 of the full load jet diameter J. The other sections such as 12, 12 and the discharge H lie on similar involutes and are thus equidistant throughout their length from each other. The portions of the master curve 6, 6 outside the master portion are not on the involute but the part radially inside the point F 1  is, for a distance of at J least -, similar to that radially outside the 2 point F 1 . Similarly the part outside the point F 4  is similar to that inside the point F 4 . Curves of sections of the discharge portion outside the master portion are also equidistant from each other throughout their length. The inlet angle increases with increasing radius and the inlet portion is designed to pass water to the discharge portion at a constant angle at all radii. Whirling annular jets produced by known methods may be used instead of separate jets.

Abstract: 169,007. Macrorie, A. K., and Shearing, G. June 15, 1920. Thermionic modulating systems and apparatus; thermionic oscillation generators. - In a method of transmitting in wireless telegraphy and telephony in which the aerial oscillations are modulated by varying the grid potential of an oscillating valve, a circuit containing a two-electrode valve and an auxiliary source of current is connected to the grid and arranged to cause a current to flow through the grid leak resistance of the oscillating valve to increase the mean negative potential of the grid .and thus decrease the aerial current. The oscillating valve W, Fig. 2, has its anode C coupled to the aerial A through a condenser B, and its grid circuit inductively coupled to the aerial coil Q through the coil N and variable condenser P. The two-electrode valve H is connected to the grid D and in series with the secondary L of a transformer, in the primary circuit of which is an alternator. During part of one half of each cycle the filament of the valve H becomes sufficiently negative to cause a current to flow through the valve and through the grid leak resistance G. In an alternative arrangement, the two-electrode valve is connected in series with a high-voltage battery and a signalling key, the closing of the key rendering the filament negative as described above. For telephony, a microphone and battery replace the alternator shown in Fig. 2. The grid leak resistance may be made inductive to lessen the abruptness of the growth and decay of the aerial current.
