Patent EP-0329238-A1 (EP)
Inventor: GEDDES RONALD CLARKE
IPC: G11C16/12
Filed: 1989-02-13
Abstract: The invention relates to an integrated memory circuit, comprising a high-voltage switch which is connected between a programming voltage generator and an erasable programmable memory. In the preferred embodiment of the memory circuit, the switch comprises a first transistor of the field-effect enhancement type which is connected between a high-voltage point and a control electrode of a second transistor, also being of the field-effect enhancement type, which is connected between the high-voltage point and the control electrode of the first transistor. By driving the two control electrodes by means of mutually complementary clock signals,  via  a capacitance, the programming voltage is step-wise built up on the control electrodes of the cross-­wise coupled transistors. The switch is less susceptible to crosstalk on the clock lines and is realized using fewer masking steps than the prior art switch.

Abstract: The invention relates to a method for on-machine winding of a web (W), in which method a Pope-type reel drum (10) or corresponding reeling means is used and over which the web (W) to be wound is conducted. In the method, new reel spools (11) are brought into contact with the reel drum (10), after which the web (W) is conducted from the fully wound roll to be wound onto the new reel spool (11). In the method primary forks (14), when in their upper position, pick up an empty reel spool (11A,11B) without any auxiliary equipment. Guided by the primary forks (14) and supported on support plates (17) attached on the primary forks (14), the empty, preaccelerated reel spool (11B,11C), is brought into nip contact with the rotating reel drum (10) and through the nip of which the web (W) to be wound runs, and is wound round the reel spool (11) at the nip contact. The support plates (17) remain in such a position while the primary forks (14) are being lowered that the contact pressure between the reel spool (11C-11E) and the reel drum (10) remains substantially constant while the primary forks (14) are moving from the upper position to the lower (see vector diagrams, Fig. 2). When the primary forks (14) are in the lower position, the support plates (17) turn into such a position that they may pass the reel spool (11), which is already positioned on the reeler tracks (12), when the primary forks (14) are moving back into their upper position, and the above steps are repeated when it is time to exchange reel spools (11) again and the support plates (17) are ready to receive one. The invention also relates to the apparatus used in the method.

Abstract: A noise removing circuit has first and second MOS FET circuits (11), (12) which have respectively different circuit threshold levels for inverting the input signal and a third circuit (13), (14) which is responsive to the output signals generated by the first and second MOS FET circuit (11), (12) to remove intermediate noise on the input. The noise removing circuit eliminates the effect of noise at an intermediate level (between the low and high levels) which influences the operation between the circuit threshold level of the first MOS FET circuit (11) and the circuit threshold level of the second MOS FET circuit (12).

Abstract: In a cassette for dispensing flexible tubing (4), the tubing is packed in a tightly layered mass between a tubular core (1) and the vertical wall of a casing (2,3). Subsequently a cap (5) is mounted in an expanded portion (8) of the casing (2). The cap (5) has a vertical part (7) fitting the portion (8) and a flange (5) partially overlapping the pack. The cap is secured against rising by punching tongues out of the portion (8) that engage in a groove (11) in the part (7). The inner surface of part (7) aligns with surface (13) of casing (2). The junction (15) beneath expanded portion (8) prevents cap (5) from descending as the tubing is dispensed from the top of the pack, over the core edge (14) and through core (1).

Abstract: A discharge tube arrangement comprises a launcher (60, 110) and a discharge tube (62, 112) positioned in part within the launcher (60, 110). When the launcher (60, 110) is energised with radio frequency (r.f.) power, surface waves are excited in the discharge tube which contains a fill. An electrically conductive structure (64, 79, 80, 114, 118, 120, 122) extends along the discharge tube and is connected to an earth when in use. The structure (64, 79, 80, 114, 118, 120, 122) is separated from the discharge tube (62, 112) by a radial distance such that, in use, the discharge tube (62, 112) produces an increase in total light output over the total light output of a discharge tube not having this structure. The structure (64, 79, 80, 114, 118, 120, 122) comprises an insufficient quantity of material to obscure this increase in total light output.
