Patent DK-8400311-A (DK)
IPC: A61B5/0484
Abstract: An averaging method for elimination of periodic stray signals, such as stray signals originating ain an environment (2) comprising a main signal source, which method is employed in a system for measuring evoked responses during an averaging procedure run in an averaging computer (7) which processes a set of signals picked up from an examined subject (10), e.g. a human scalp, by means of electrodes (11) which set of signals is fed through an instrumentat ion amplifier (9) to an averaging computer (7). A counting circuit in the system for measuring evoked responses comprises a sensing circuit (1), a circuit (3) detecting signal half-periods, a counting circuit (5) and a triggering circuit (6), and introduces permanent desynchronization between the frequency 1/T of external stimuli signals, e.g. from a photostimulator (8), and the sweeps of the averaging procedure in the averaging computer (7) both in relation to the frequency 1/T of the periodic stray signals resulting in amplitudes of the stray signals being substantially completely eliminated.

Abstract: 1,233,356. Bottle filling machines. A.P.V. CO. Ltd. 5 Feb., 1970 [21 Feb., 1969; 31 March, 1969], Nos. 9559/69 and 16750/69. Heading B8T. A method of cleaning suction filling machines, especially the filling nozzles, is characterized by the filling nozzle valves being held open by an attachment, while cleaning fluid is flushed through them. The filling machine.-A filling machine for which the cleaning method is intended comprises a bowl 1 for the product, with filling valves 6 attached to it. The bowl 1 carries a product inlet 2, surrounded by a tube 19 for carrying cleaning fluid into the bowl. The bowl is equipped with a liquid level control device 3 which can control the product level at level 1a during normal operation, and the cleansing fluid at level 1b during cleaning. An attachment 42 is attached to each of the filling nozzles 6 during cleaning. The cleaning fluid is cycled from tanks 16a, 16b by a pump 17 and pipes 18, through pipe 19 which has perforations 20 both at its lower end and at its upper end within the port 13 of the bowl, through the bowl, through the filling valves, and back through the bowl, the product inlet pipe 2, pump 21, and finally into vessels 16a and 16b. The filling nozzle cleaning attachment 42 comprises a tube 39 which may be attached to the filling nozzles by pins 26, carrying at its lower end a chamber 41 surrounded by a flexible wall 37. The attachment has a partition 27 which when it is in place holds the valve 6 in the open position. A tube 40 is held by the partition just beneath but not in contact with the vent nozzle 10. A valve disc 29 is attached to tube 40. In operation the cleaning fluid flows down through the valve 6 through the perforations 30 in the partition 27 and into the lower chamber 41. The lower chamber 41 is periodically compressed, e.g. by star wheel 43. This causes the fluid pressure in chamber 41 to rise and valve disc 29 to seat against perforations 30 preventing cleansing fluid flowing through these into the valve. The cleansing liquid is therefore forced up through passage 40 and out through gap 32 between pipe 40 and the venting tube 10, and also up through venting tube 10 into the product bowl 1. In a second embodiment, Fig. 2, accompanying Provisional Specification 9559/69 (not shown), the lower chamber (24a) is rigid, and equipped with an air vent valve which connects to atmosphere. During cleaning the product bowl 1 is under vacuum, liquid flows through the valve, through perforations (30), into the lower chamber (24a). The air vent valve (35) is periodically opened to atmosphere forcing the liquid up through passage (31) and out through gap (32), as in the previous embodiment, the valve member (29) again seating against the perforations (30).

[Also in Divisions G2-G3] A cassette contains a magnetic tape, mounted for unwinding and rewinding on a rotary support, and a compartment for releasably housing an optical slide. A projector uses magazine loading of such cassettes and follows an automatic cycle in which each cassette in turn is moved into the operative position, the slide is withdrawn to a projection position, a portion of the tape is pulled out of the cassette so that a drive capstan can be inserted behind it (Figs. 5 to 10, not shown), the tape is played back and then rewound from a take-up reel to a supply reel, and the slide is returned into the cassette. The length of the projection and playback period for each cassette is determined by the setting of an adjustable stop on the cassette, a control switch being driven towards the stop by the tape drive mechanism (Figs. 11 to 16, not shown). The projection and playback of a cassette may be repeated. A master projector may control one or more slave projectors so as to project a succession of slides during the playback of a single tape (Fig. 29, not shown).

Abstract: 1310157 Control systems for resistance welding POWER CONTROL CORP 8 April 1970 16755/70 Heading H2H [Also in Division B3]  In resistance seam welding, particularly of the overlapped edges 12 of can bodies 10 traversed relative to a pair of electrodes 14, 16, a steady state direct current is passed between the electrodes 14, 16 the magnitude of the current being sufficient to raise the temperature of the edges to a point slightly below the melting point, and current pulses are superimposed on the steady state current, of sufficient magnitude to raise the temperature of the metal to its melting point thus producing along the seam a line of contiguous spot welds. The welding electrode may comprise a pair of wheels, one of which, 16 is mounted on a mandrel around which the can bodies are formed. In a suitable electric circuit a threephase source 24 is connected through a variable controller 26 and threephase transformer 28 to a rectifier 20 the output of which is smoothed by a capacitor 22 and applied as a steady D.C. voltage to the electrodes 14, 16. The circuit also includes an inverter 30 of the semi-conductive-controlled rectifier type controlled by a firing circuit 32, the inverter converting the D.C. output from a rectifier 34 into a square wave output. This output is applied through transformer 36 to a circuit 38 comprising a pair of silicon controlled rectifiers 40, 42 having their anodes connected to the ends of the secondary winding of transformer 36 and their cathodes connected to the upper electrode 14. The lower electrode 16 is connected to a centre tapping on the secondary winding. A firing circuit 44 controls the point at which the rectifiers 40, 42 fire thereby controlling the power applied to the electrodes. The frequency of the output of the circuit 38 is double that of the inventor 30. An inductive choke 18 isolates the rectifier 20 from the high frequency pulse output and diodes 46, 47 serve to prevent arcing between the electrodes 14, 16 when the latter leave the end of a can body. In an alternative method an alternating current is superimposed on the steady-state direct current.
