Abstract: 1,229,122. Percussive tools. ATLAS COPCO A.B. 8 May, 1969 [8 May, 1968], No. 23430/69. Heading B4C. A percussive tool, e.g. a rock drill, comprises an anvil 12 in contact with an annular damping member 13 such that on the downward stroke of the anvil to strike a tool bit 22, air in a chamber 14 between the anvil 12 and damping member 13 is compressed to urge the anvil 12 upwards. On the upward stroke, a flange 15 on the anvil 12 contacts a rim 16 of the damping member 13 and this member 13 is of such a mass that it absorbs all the kinetic energy of the anvil 12 which is consequently stopped. The drill may be operated by an I.C. engine having a piston 3 connected to a crank-shaft 6 to which a driving piston 8 is similarly connected. Air is drawn into the compression chamber 11 between the driving piston 8 and anvil 12 through a port 10 and may be expelled through passages 23, 24 and 29 to the flushing duct 25 of the drill bit 22. The damping member rests on a shoulder 18 until it is lifted by the anvil 12, and the distance "a" between the driving piston 8 and the anvil 12 may be chosen for optimum efficiency.

Abstract: 1,233,517. Automatic arc furnace control. LEYBOLDHERAEUSVERWALTUNG G.m.b.H. Nov. 18, 1969 [Dec.18, 1968], No. 56497/ 67.  Heading G3R. The feed of the consumable electrode of an arc furnace is controlled by continuously comparing the arc voltage with a reference voltage to derive a difference voltage, separately integrating the positive and negative pulse portions of the difference voltage, adding the integrated signals algebraically in accordance with the pulse polarities to derive an output signal and using the latter to control the electrode feed mechanism. The positive and negative difference voltages are detected by resistor/diode circuits 8, 11 and 9, 10 respectively, the arc voltage U L  being filtered at member 3 to remove unwanted frequencies (e. g. rectifier harmonics) and compared across the circuits 8, 11 and 9, 10 with a reference voltage U S . The outputs of the resistor / diode circuits are applied to respective RC circuits 12, 13 and 14, 15 chosen so that the relays 16, 17 controlled thereby respond only to the pulse portions of the difference voltages applied to the RC circuits. Each relay contact 18, 19 controls the application of a D.C. supply 28, 29 to a resistor 20, 21 so that constant amplitude square wave pulses are produced across these resistors, which pulses have a duration dependent on the length of the respective positive or negative pulses producing them. The outputs of resistors 20, 21 are applied to respective integrating circuits 22, 23 and 24, 25 whose outputs are algebraically combined to produce a continuous signal at terminals 26, 27 for application to a conventional servomotor controlling the electrode movement. If the electrode spacing is correct the positive and negative pulses cancel one another out, but if the spacing becomes too great or too small the positive or the negative pulses respectively preponderate to produce an appropriate control signal, Fig. 2 (not shown). In a modification Fig. 3 (not shown) the relays are replaced by transistor switches and the resistor/ diode circuits by RC circuits and a potentiometer whose output supplies the transistor switches.

Abstract: 1,234,212. Testing filter cigarettes. MOLINS MACHINE CO. Ltd. and T. ROWLANDS. 9 Aug., 1968 [10 Aug., 1967], No. 36820/67. Heading A2C. Filter cigarettes comprising filter plugs united to cigarette portions by encircling bands, are tested for insufficient adhesion between the cigarette portion and the uniting encircling band by subjecting the filter plug to suction to urge it endwise away from the cigarette portion while holding the latter against movement with the plug. Filter cigarettes are fed from a conveyer 22 to a drum conveyer 21 to which they may be held by suction or by an arcuate guide, and are thence transferred to flutes 3 of a testing drum 1. The cigarettes are then urged endwise in the flutes 3 by a cam plate 24, acting on their ends remote from their filters, and aided by weak suction applied through ports 16, to cause their filter ends to enter holes 5 to the extent shown in Fig. 2. Suction applied to radial bores 15 in the grooves 3, holds the cigarettes to the drum 1 over that part of its rotation over which an arcuate slot 10 extends in a stationary disc 6. Suction is also applied via an arcuate chamber 17, an arcuate slot 11 in stationary discs 9, 7, and the ports 16, to each hole 5. The strongest suction is applied where the chamber 17 overlaps the slot 11 and is of a suitable strength to separate only insufficiently adhered filter stubs from the cigarettes and to suck them right into the holes 5. Subsequently compressed air, applied through an arcuate chamber 26, returns the cigarettes to their original positions in the flutes 3 determined by a stop plate 25 for transfer back to the conveyer 22 by a drum 23. The conveyer 22 supports the cigarettes at their ends only so that separated cigarettes and stubs drop away into a box 29. Any plugs remaining in a hole 5 are ejected by a further blast of air from a chamber 27 into a box 28. A leaf spring 20, mounted on an extension 19 of the disc 9, rides over an unseparated cigarette but bends over an outstanding edge of the uniting band of a separated plug to prevent it subsequently slipping back over its detached cigarette.

Abstract: 1,239,210. Ignition systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov.18, 1968 [Dec.1 1967], No.54835/67. Heading F1B. An ignition system comprises an oscillator VT1, a spark producing circuit 13, 14, VT4 which on receiving an input from the oscillator produces a spark at a plug 22 of the engine, means coupling the oscillator to the spark producing circuit and means (not shown) driven by the engine for controlling the oscillator to determine the instants at which sparks are produced. The oscillator is provided with both positive and negative feedback L2, L1 so that when no spark is required the oscillator does not oscillate. The means driven by the engine serves to increase the positive feedback when a spark is required and so cause the oscillator to oscillate. Each spark is produced when the switching device VT4 is turned off and a monostable circuit driven by the output from the oscillator serves when in its unstable state to turn the switching device off. The oscillator used starts suddenly when the coupling between the coils L2 and L3 is increased. The spark is produced substantially instantaneously when the ferrite rod (not shown) passed over the core of the coils.
