Title: Label wrapping machines
Inventor: BUTCHER PETER EDWIN
IPC: B65C9/16
Filed: 1983-09-29
Abstract: A label wrapping machine has a turntable (10) carrying a plurality of wrapping stations (14). A label feeding station (28) feeds labels having adhesive applied to one end only to the pair of gripper assemblies (22 and 20) of each wrapping station (14) as it passes. Downstream of the label feeding station (28) is a can feeding station (24) which feeds cans (8) to each wrapping station (14) as it passes. 
<??>Each wrapping station (14) has a rotatable circular platform (18) for receiving a said can (8) and a belt providing an operative run. In a first configuration the run is rectilinear and a central portion thereof urges a central portion of the label into contact with the can (8). 
<??>In a second configuration the operative run becomes circular and in so doing wraps itself and the label around the can. Rotation of the belt brings the overlapping portions of the label into contact with each other and since adhesive has already been applied to one of the portions of the label will be tightly secured on to the can. No adhesive lies between the can and the label.

Title: Producing filler material, particularly for cigarette filters
Inventor: ARTHUR HUGH MACDONALD
IPC: A24C5/39
Filed: 1984-07-25
Abstract: Filler material, particularly for cigarette filters, is produced by feeding a first stream (72) of substantially continuous filaments of filler material onto a pin roller (80) which is driven at a speed such that the filaments are broken by the pins into irregular lengths and are projected from the roller in random orientations. The broken filaments are collected on a carrier stream (74), also comprising filamentary material, for delivery to a rod-making unit (92). More than one stream could be supplied to the pin roller so that the broken filaments can comprise a mixture of filaments of different filler materials. The carrier steam may comprise filler material which is different from that in the first stream and may comprise a fibrillated web. <IMAGE>

Title: Thyristor-controlled reactor circuit
Inventor: AINSWORTH JOHN DESMOND
IPC: H02J7/16
Filed: 1984-11-19
Abstract: A control circuit for a 3-phase thyristor-controlled reactor in which the reactor phase currents are basically controlled in known manner in dependence upon the terminal voltages so as to tend to maintain the terminal voltages equal and constant, also includes an over-riding phase current control circuit 12 which tends to maintain the phase currents equal at the expense of the terminal voltage equality. In a modification, equal- current control is replaced by equal- terminal-voltage control if terminal voltage unbalance exceeds a predetermined level. A hybrid arrangement is also provided in which a compromise between equal phase currents and equal terminal voltages is reached. The control circuit 12 receives inputs from current transformer circuits 13, 14, 15 and includes integrating operational amplifiers 37, 38. <IMAGE>

Title: Vacuum sputtering apparatus
Inventor: DUCKWORTH ROGER GEORGE
IPC: H01J37/34
Filed: 1985-05-30
Abstract: The vacuum sputtering apparatus comprises a high vacuum coating chamber (14), an ionisation device (30), which includes an electrode assembly and at least one target rod (32), mounted on the coating chamber and communicating with the interior thereof, and a further high vacuum chamber (16) linked to the coating chamber. Both chambers can be evacuated and an ionisable gas, e.g. argon, can be fed into the coating chamber. There are two aligned access openings (15, 56). The access opening (15) is closed by a sliding closure (18) and the access opening (56) is closed by a door (62) on a lifting device (58, 60). The lifting device (58, 60) supports the objects (54) to be coated and lifts them firstly into the chamber (16) whereupon the door (61) closes the openings (56). The chamber (16) is then evacuated, and subsequently the closure (18) is opened and the lifting device operated to lift the objects (54) into the coating chamber (14). The lifting device also incorporates a rotation mechanism for rotating the objects (54) whilst they are in the coating chamber and may also incorporate a heating or refrigeration unit to heat or cool the objects (54). <IMAGE>

Title: Multiplex data receiver with improved timing phase control apparatus
Inventor: AOYAGI HIDEHITO
IPC: H04L7/00
Filed: 1985-09-06
Abstract: A multiplexed signal received at a terminal (10) is digitized by a sampler (1) and applied to a demodulator. The individual baseband signals are equalized in power by AGC amplifiers (4A-4N) controlled by power level detectors (5A-5N) producing power level signals PA-PN). The signals are then applied to adaptive transversal equalizers (DA-DN) which produce deviation signals (DA-DN) indicating on a channel-by-channel basis the phase error in the sampling signal applied to the sampler (1) by a VCO(2) which is controlled by a frequency control circuit (8). In order to ensure that this circuit acts only on the basis of information from good channels, a selection circuit selects from the deviation signals (DA-DN) only those whose power level signals (PA-PN) are above a given threshold. The control circuit (8) averages the selected deviation signals to provide the control signal for the VCO(2). Various alternatives for deriving and selecting the deviation signals are disclosed. <IMAGE>

Title: Coupling torque limiter
Inventor: FUKUMOTO MASAO
IPC: F16D7/08
Filed: 1985-10-02
Abstract: A torque limiter is built into a rotation-transmitting coupling and used to prevent an excessive load applied to an output element (24) from being transmitted back to an input element (21). The torque limiter includes a ring plate (22) having holes (23) containing balls (26), which plate is fixed to and rotates with an input element (21). A ball seat formed by the surface of an output element (24), is provided with tapered holes or recesses (30) for receiving the balls, and a thrust seat (25) is provided, having a surface which is pressed against the balls. The ball seat and the thrust seat are disposed on opposite sides of the ring plate so as to compress the balls (26) located in the holes (23). The rims of the tapered recesses (30) are rounded into arcuate form, and circular grooves such as, (33) are formed in at least one of the opposed surfaces of the ball seat and thrust seat. This configuration greatly reduces the contact pressure between the balls and the opposed surfaces when an excessive load is applied to the output element and the balls roll around in the grooves. <IMAGE>
