Abstract: 1,184,389. Washing gases. C.I.T.-COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 19 Dec., 1967 [19 Dec., 1966; 25 Sept., 1967], No. 57651/67. Heading B1R. Apparatus for purifying gas comprises a cylindrical metal vessel 31 into which the gas to be purified is introduced tangentially at 32, atomisers in an upper portion of the vessel to spray the gas with a fine mist of a purifying liquid and a duct 35 opening at its lower end into the vessel 3 and having means 36 to control the speed of entry of the gas being purified into the duct, the gas entering the duct being again sprayed with a fine mist of purifying liquid above the means 36 and then passed upwardly over spikes 38 projecting inwardly from the inner wall of the duct before discharge at the top of the duct. The liquid atomisers may be operated with a gas under pressure or as shown have means to give the fine mist produced an electrostatic charge. Again as shown the atomisers 42 in the vessel 31 are arranged on a helical line and one pole of an electrostatic generator 43 is connected to the atomisers 42 and the other to the metal wall of the vessel. The polarity of the charge given to the fine mist may be varied cyclically and in a modification the polarity of the charge given to the fine mist in the vessel 31 may be opposite to that given to the fine mist in the duct 35. The means 36 controlling the speed of entry of the gas into duct 35 comprises a ring of upright blades 11 (Fig. 4, not shown) the position of which can be varied from outside the vessel 31. The spikes 38 which remove excess liquid from the purified gases may be electrically charged at least at their tips. Alternatively they may be hollow and form part of a system including a doublewalled section of the duct 35 through which a cooling liquid may be circulated. The purifying liquid may comprise surface active agents or substances capable of reacting with particular components of the gas to be purified. Thus e.g. alkaline substances may be used to remove acidic oxides and basic sulphate of tri-valent chromium may be used to remove polyphenols.

Title: Semi-conductor alternating current regulating means
IPC: G05F1/455
Filed: 1971-12-20
Abstract: 1380079 Automatic control of temperature KALLE AG 20 Dec 1971 [18 Dec 1970] 59086/71 Heading G3R In an automatic control system particularly for temperature control of a plastics extruder, wherein heating coils (13) Fig. I (not shown) are energized by A.C. under the control of a triac 39 Fig. 6, the extruder temperature is detected by a thermocouple and compared in a controller 16 Fig. 2 with a desired value to produce a D.C. error signal. The error signal is converted by a voltage converter 28 Fig. 2 and Fig. 5 (not shown) into a control signal which is a function thereof but is electrically isolated therefrom by virtue of a transformer coupling in the converter. The triac is controlled so that it is fired substantially at zero voltage of the A.C. supply and it is arranged that it will always conduct an even number of successive half-cycles of current (otherwise a D.C. component would arise). Thus the average power supplied to the heating load is varied by changing the on/off duty cycle of the triac, controlled bursts of complete cycles being applied to the load. In Fig. 2 the error signal from a controller 16 is converted at 28 to a control signal in analogue form. This signal is converted to digital form in an amplifier/comparator 25 by means of a sawtooth signal from a generator 27. As shown Fig. 6, the output of amplifier 25 controls an SCR 36 to render it conductive so that C38 is charged each negative half-cycle. Zero cross-overs are "sensed" by transistors 49, 50, the alternating voltage across triac 21 appearing across R46, R47 in the respective base/emitter circuits thereof. Thus 49, 50 conduct to provide gate pulses to SCRs 42, 41 respectively at the beginning of each negative and positive half-cycle respectively. To ensure that triac 21 will conduct for an  even number of half-cycles, C38 is charged sufficiently during each negative half-cycle to enable SCR 41 to conduct a gate pulse to the triac during the following positive half-cycle after the control signal has terminated. Alternatively the error signal may be in digital form in which case the sawtooth generator is unnecessary Fig. 3 (not shown).  As a further alternative the output stage of controller 16 may be a relay contact which is opened and closed with a mark/space ratio proportional to the error.

Filed: 1971-12-22
Abstract: 1344299 Electric motors; control of brushless motors SIEMENS AG 22 Dec 1971 [23 Dec 1970] 59696/71 Headings H2J and H2A [Also in Division G3] A brushless motor has stator windings in series with switch means across a D.C. supply the switch means being controlled in dependence upon motor speed, as sensed by the windings, and rotor position, the latter control being reduced above a predetermined motor speed. In an embodiment, a brushless motor, Fig. 1 (not shown), has stator windings W 1 -W 4  connected across a D.C. supply through power transistors T 1 -T 4  and a common transistor T 15  transistors T 1 -T 4  being controlled, on increasing speed from starting, by Hall generators H 1 , H 2  in dependence upon position of the permanent magnet rotor. Above a predetermined motor speed, a speed dependent signal from transistors T 9 -T 12 , which are connected to and sense the voltage across the windings W 1 -W 4 , progres-   sively turns on transistor T 13 , to turn transistors T 14  and To progressively off, reducing the control by the Hall generators H 1 , H 2 . Simultaneously, transistors T 1 -T 4  are sequentially and increasingly controlled by transistors T 9 -T 12 , until transistor To is turned off and total control of transistors R 1 -T 4  is afforded by transistors T 9 -T 12 . Also as transistor T 14  turns off, it turns transistor T 15  progressively off to regulate the motor speed to its rated value. The speed at which the reduction of control by the Hall generators is initiated may be adjusted, by varying the bias resistors on transistor T 13 .

Patent GB-2013462-A (GB)
Title: Overload Coupling
IPC: F16D43/206
Filed: 1979-01-29
Abstract: An overload coupling 9 in a machine 1 comprises two coupling members between which is disposed a coupling ring. The coupling ring is movable upon overload to release the coupling to interrupt the drive to the machine 1. Means, which may comprise a brake including a carrier 41, is provided for reestablishing the driving connection after overload. This means is actuated by the performance of an operation on the machine, the primary function of which operation is independent of the overload coupling. In the illustrated embodiment, the operation is the raising of the machine using a lifting device 3. In an alternative embodiment, the operation is the reduction of the speed of the power take-off shaft 7. The coupling 9 comprises a power input member 18 carrying spring-loaded balls 20 and an output member 13 having formations (36, 37) which interfit with the intermediate coupling ring 27. The balls 20 cause the ring to move with the input member 18 but, upon overload, the balls move into deeper recesses (29) in the coupling ring allowing the ring to move axially away from the output member 13 which becomes uncoupled. Application of the brake 41 causes the balls to reseat in their original shallower recesses (32) and plungers 34 move the ring back into engagement with the output member. <IMAGE>

Title: Forage Harvester
IPC: B24B3/36
Filed: 1979-07-05
Abstract: A forage harvester has a knife sharpening mechanism for its cutterhead (24). A carrier (88), provided with a sharpening stone (102), is mounted on a transverse beam support (62) parallel to and adjacent the cutterhead (24) and is reciprocated by manual action with the stone (102) in contact with knives (26) of the cutterhead (24) whilst the cutterhead (24) is rotated in reverse, to sharpen them. In order to make the carrier (88) less susceptible to becoming stiff to move, it is mounted on the support (62) by way of linear ball bearings (90). Furthermore, the sharpening stone (102) is permanently bonded to the carrier (88), rather than being clamped thereto, which enables a greater proportion of the stone (102) to be used before replacement is necessary. The carrier (88) has plates (96) extending to embrace a beam (60) parallel to the support (62) for bracing the carrier. The support (62) is actually manually adjustable and downward adjustment is prevented by an interlock when a top-and-rear access door is open. <IMAGE>
