Patent GB-2081940-A (GB)
Title: MOS transistor circuit
IPC: G05F3/24
Filed: 1980-08-05
Abstract: With an integrated circuit using MOS transistors it is often necessary to be able to generate the inversion threshold voltage VT accurately. The present invention achieves this with an all-MOS transistor circuit. In this circuit, a p-channel enhancement-mode transistor (M5) is in series with two series circuits (M1-M2 and M3-M4) each of which includes two series-connected MOS transistors. In the first series circuit the transistors (M1, M2) are diode-connected, and in the second series circuit one transistor (M3) is diode-connected. The other transistor (M4) of the second series circuit has its gate connected to the junction between the two transistors (M1, M2) of the first series circuit. By suitable proportioning of the transistors (M1, M2, M3, M4) in the two series circuits, and especially by suitable choice of the aspect ratios of their channels, the voltage produced at the junction of the transistors (M3, M4) of the second series circuit, which is the circuit's output, is equal to VT. By using MOS transistors for this circuit, an arrangement is produced which is compatible with the MOS devices for which it produces the voltage VT.

Patent GB-2087305-A (GB)
Title: Sealing thermoplastic film layers
IPC: B65B51/18
Filed: 1981-11-17
Abstract: A machine for sealing polyethylene bags or the like of the type having conveyer bands for gripping and transporting the bags to be sealed at a constant velocity from the machine's inlet end, through a heating station, then through a cooling station to the machine's outlet end. The conveyer bands are formed from a material having good release (non-stick) characteristics with respect to the fused thermoplastic. Disposed at the heating and cooling stations, respectively, are heating and chilling bars (heat transfer bars), each being disposed in pairs on opposite sides on and in proximity to the conveyer bands. Means are provided for cyclically opening and closing both pairs of bars relative to the conveyer bands and for translating the bars longitudinally in reciprocating fashion with respect to the moving bands. As bags to be sealed are carried along by the conveyor bands, the heat transfer bars pinch closed on the traveling bands, but since the bars at this time are being translated in the same direction of travel (forward stroke) and at the same velocity as the bands, no band wear occurs. Toward the end of this forward stroke, the heat transfer bars open relative to the bands and the return stroke occurs with substantially zero force between the moving bands and the heat transfer bars. During the return stroke, the bars act as a preheat device to warm up the film prior to the forward stroke to obtain greater speed. Because the bars are of a predetermined greater length than the length of the reciprocating stroke, a continuous package seal is ensured.

Title: Liquid container with combined measuring and closure cap
Inventor: BARKER DALE EDWIN
IPC: B65D47/40
Filed: 1983-11-16
Abstract: A liquid container 74 dispenses liquids without mess and incorporates a measuring cup 16 which is also the closure for the container. The container has a dispensing orifice 80 for the stored liquid product, a transition collar 14 which is attached to the container finish 72 surrounding the orifice, the collar 14 including an extended pouring spout 56 and a transverse partition 55 which drain 54 to collect and return residual liquid to the container, and a measuring cup 16 with an open mouth having threads 40 on its exterior to attach the cup to threads 58 on the interior of the transition collar where it functions as the closure for the package. Because of the extended pouring spout, the residual liquid drain back feature, and the exterior threads on the measuring cup, virtually all mess normally associated with liquid product measuring and dispensing is obviated. The transition collar may be connected to the container finish by paw-like locking teeth which prevent the collar from rotating relative to the container as the cup 16 is rotated for removal. The cup 16 has a drip prevention peripheral lip which seals against annular wall 57 of the collar, and an outwardly extending shoulder 38 which seals with the upper peripheral surface 59 of the transition collar. The threads 40 on the cup may include a groove for venting purposes. <IMAGE>
