Paddde fans and pumps.-A blower or pump has one or mnre rod-like or tubular members arranged radially on a shaft so as to be rotated without the rods or any associated members closely conforming to an external casing. In the form shown in Fig. 2, a shaft 1 driven by a motor 2 carries radial rods 3. On each side of the rods are stationary discs 4, 5, the former 4 having a central inlet and the latter 5 carrying a ,stuffing-box through which the shaft 1 revolves. In a modification, two sets of rods are used and the peripheries of the discs 4, 5 are joined to form a casing with an outlet pipe. In another modification, the rotating shaft 9, Fig. 6, is hollow and is fitted with tubular members 10: air passages 11 are provided at the centre of the side discs. In another modification, a star formation of hollow members is employed and their outer extremities are flush with the wall, 14, Fig. 7, joining the peripheries of the discs. Holes 17, 18 enable air to take an outward path through the casing during rotation of the apparatus. In the forms with hollow members mercury or other liquid may be used to expel the pumped fluid, the mercury being collected and returned to the apparatus. Where a number of hollow members in different parallel planes is used, tubes extend from the outer cylindrical surface of the casing to points near the hollow shaft, to supplement the supply of air or other fluid drawn in through the central apertures in the ends of the casing. In the form shown in Figs. 9 and 10 the rods 26 are mounted in a split shaft 27 and draw air from one side or the other of the wall 24 according to their position on the shaft. In a modification, the rods are mounted upon a sleeve carried by the shaft along which it can be axially moved. In the modification shown in Fig. 13, each rod 31 is provided at its centre with a ball working in a split hollow shaft and round which the rods can swing to clear the opening in the wall while they are moved axially along the shaft.

Title: Dropout compensation device
IPC: H04N9/88
Filed: 1976-05-27
Abstract: 1533609 Colour television dropout compensator NORTH AMERICAN PHILIPS CORP and PHILIPS GLOEILAMPENFRABRIEKEN NV 27 May 1976 [30 May 1975] 22059/76 Heading H4F Dropout compensation for a colour television signal (e.g. NTSC signal) at input 1 from a record disc or tape which is modulated on a carrier wave, is effect by deriving the one line period delayed 12 luminance component Y' directly from input 1 without first demodulating 8 the colour signal from its carrier wave. This arrangement enables an ultrasonic delay line 12 to be used without first having to remodulate the luminance component on a carrier wave. Specifically the luminance component is delayed 12, demodulated 21, filtered 22 and added 18 to the filtered 15, delayed 16, variably amplified and phase inverted 17 (to compensate for half-line offset in NTSC) chroma signals. The output of adder 18 is substituted by switch 3 for the direct output of demodulator 8 whenever a dropout is detected 2. In a second embodiment (Fig. 3, not shown) the input to chroma filter 15 is derived from the output of switch 3. In a third embodiment, Fig. 4, switch 3 is ganged to further switches 23 and 28 in the chroma and luminance signal compensating signal deriving circuits. Switch 28 causes a luminance compensating signal deriving circuits. Switch 28 causes a luminance component to be available even if the dropout lasts longer than one line period or occurs exactly one line period after a previous dropout. A similar arrangement may be provided for the chroma component.

Patent GB-465514-A (GB)
Title: Improvements relating to high voltage generators for particles precipitating plant
IPC: B03C3/66
Filed: 1935-08-06
Abstract: 465,514. Dynamo-electric machines. PESTARINI, G. M. Aug. 6, 1935, No. 22187. Void. Convention date, Aug. 3, 1934. [Class 35] Exciting.-An electrical plant connected to a load which is such as to give rise to frequent arcing or short-circuiting between the load terminals, e.g. a particle precipitating plant comprises one or more metadyne generators the primary brushes of which are short-circuited either directly or through a stator winding of the machine. As shown in Fig. 1, the primary brushes a, c are short-circuited and the secondary brushes d, b are connected to the electrodes of a precipitation chamber 3. The stator has a separately excited secondary variator winding 2. In a modification the primary bushes are closed through a stator winding inducing a flux which opposes the primary current. If this winding is so placed as to induce an E.M.F. between the secondary brushes also, and acting in the same direction as the primary rotor ampere turns, it will act to reduce the primary current. The primary circuit may be connected to the machine frame when a single rotor winding is employed. Separate armature windings may be associated with the primary and secondary circuits, or the secondary armature circuit may comprise several series connected windings. To increase stability, the secondary current should be reduced when the secondary voltage exceeds the normal operating value. Fig. 4 shows an arrangement for this purpose in which the secondary variator winding 2 is supplied from an auxiliary generator 5 having a shunt winding 6 and a winding 7 carrying the primary current. The primary current also traverses a stator winding 4 producing an E.M.F. between the brushes a; c which opposes the primary current. The auxiliary generator is driven at constant speed. The machine 5 may be replaced by a small metadyne generator. It is sometimes desirable for the secondary current to increase slightly with the voltage at first, and for this purpose, the voltage supplied to the secondary variator winding by the auxiliary generator is caused to increase slightly when the secondary voltage rises, and the magnetic circuit of the metadyne is such that it becomes saturated quickly as soon as the secondary voltage reaches its normal operating value. In order to avoid the use of high voltage windings, the secondary commutating poles are excited by two coils, are traversed by the primary current and the other by the current in the secondary variator winding. The main metadyne may be connected in series with other machines, some of which may be of ordinary type giving constant voltage, provided that there is a sufficient number of metadynes to give a zero total voltage when required. The auxiliary generator may be separately driven at a controlled speed whereby the secondary current may be controlled. Specifications 415,701 and 415,720 are referred to.

Title: Device for indicating thread breakage in spinning machines
Filed: 1960-06-24
Abstract: 950,606. Alarms, indicators and thread guides in spinning machines. PATRA PATENTTREUHAND-ANSTALT. June 24,1960 [June 29, , 1959; June 1,1960], No. 22233/60. Headings DID and D1F. In a spinning frame, a thread breakage indicator mounted in the space between two spindles comprises an eye member serving as the thread guide for one such spindle and having at least one eye-forming part which is movably mounted with respect to a housing. This part is directly engaged by the tensioned thread and positively held thereby in one of its two limiting positions whilst upon breakage of the thread it moves towards the other limiting position to actuate an indicating means. In the device shown, thread passes through an eye 1 formed by parts 2 and 5 of member 6 (adjustably secured by a screw 10) and an adjustable lever 3 the movement of which to limiting positions (representing normal thread passage and breaking or cessation of thread) rotates a pivot 4 on a bearing ball 17 to cause a pin 24 carried on a reduced portion 23 to deform a spring 25 and thus maintain electrical contacts 27 and 28 apart or to allow the spring to close the contacts and so complete an earthed-return circuit to illuminate an alarm lamp 29. The working parts are contained in longitudinally divided housings 7 and 8 the latter independently openable by means of a flexible tongue 22 fitting in dust-proof manner in .grooves 21. The housing walls, where penetrated by rotary members are rendered dust-proof by seals, as at 15, or a locknut 16 associated with screw 10. Dust deposition is prevented by sloping walls at 49 and sloping projections 50, 51, adjacent passage slots 9 for lever 3 and member 6. The combined housing 7, 8, may be swung about a hinge axis 41 into the position, shown in Fig. 5, which facilitates bobbin change or thread re-engagement, the lamp circuit being interrupted by consequential disengagement of tips 33, 35, from contact plates 37. The eye 1 may be formed by two members having cooperating curved portions open on the same side, Fig. 9 (not shown) or by a single member Fig. 10 (not shown).

Title: Improvements in or relating to friction clutches
IPC: F16D13/02
Filed: 1936-08-13
Abstract: 463,608. Friction clutches. SCHULER AKT.-GES., L., and KNOCHL, L. Aug. 13, 1936, No. 22375. [Class 80 (ii)] A friction clutch arranged on the crank-shaft 2 of a press or similar machine comprises a split ring 6 rotating with the driving pulley 3 and adapted to be contracted on to a disc 5 secured on the shaft 2 on braking a drum 18 journalled on the hub of the disc 5. One end of the ring 6 bears against an adjustable wedge abutment 8 in the pulley, while the other end is acted on by one arm 10 of a bellcrank lever fulcrumed at 11 in the pulley. The other arm 12 of this lever is connected by a link 13 to an arm 14 projecting from a pin 15 journalled in the pulley, while another arm 17 projecting from the pin 15 pivotally carries a block 20 engaging a radial groove 19 in the drum 18. With clockwise rotation, the linkage, on applying a brake band 21 to the drum 18, moves to contract the ring 6 on to the disc 5, this engaging movement being so limited by a stop 24 that the linkage is not self-locking. A latch 25 carried by a pin 29 journalled in the drum 18 now engages under the action of a spring 26 with a notch in the pulley, whereby the drum is locked in its new position and the clutch remains engaged when the brake is released. A plate 28 is movable axially so as to turn the pin 29 through an arm 30 and thereby disengage the latch, allowing the clutch to disengage, the disengaging movement of the linkage being limited by a stop 25. The plate 28 is controlled through pins 48, by a cam 47 on the shaft 2 so as to disengage the clutch after one revolution. Manual disengagement at any time can be effected by means of a lever 51 acting on one of the pins 48.
