Title: Switchable torque AC motor operating valve
Inventor: FRIES JOHN W DE
IPC: H02P25/02
Filed: 1987-01-16
Abstract: A valve actuator is constructed to drive a valve member into either of two end positions, into one of which the valve member is biased by spring means, or a mid-position. The valve actuator includes an AC synchronous motor in which one of the rotor or stator windings is modified so that the output torque of the motor can be switched between a value in which it overcomes the return force of the spring means at any position of the valve member and a value which exactly balances the return force of the spring means at the mid-position. As illustrated the modified rotor or stator winding comprises two windings (18, 20) which are switched by means of a microswitch (12) between a first arrangement in which they are connected in parallel to provide maximum torque and an arrangement in which only the winding (20) is connected to the power supply to provide the reduced torque. <IMAGE>

Title: Latch-up in integrated circuits
Inventor: BERNACCHI JERALD ROY
IPC: H01L21/8249
Filed: 1988-11-17
Abstract: For avoiding latch-up in an integrated circuit, the base-emitter junction of a parasitic bipolar transistor forming part of a parasitic SCR structure is monitored. If the forward bias of the monitored base-emitter junction approaches a predetermined value (at which latch-up would occur) the operation of the circuit is altered to prevent activation of the SCR. In the circuit shown when this condition occurs FET 110 is cut off so that only FET 112, which has a relatively high impedance drain-source channel, is left to conduct. This reduces the forward bias of the parasitic SCR. In an alternative embodiment (Figures 2, 3) no monitoring of the parasitic transistor is effected, but an additional metallization line (76) so routes the power supply that the transistor cannot become forward biassed. …<IMAGE>…

Patent GB-2243554-A (GB)
Title: Catheter retainer
Inventor: HOLLANDS KEITH G M
IPC: A61M25/02
Filed: 1990-05-02
Abstract: None of the catheter retainers presently commercially available are entirely satisfactory. Surgeons therefore still quite frequently stitch a catheter to the skin of the wearer. This is frequently done when it is desired to drain a wound and yet hold the wound largely closed. This procedure of course involves a risk of infection and may be painful for the patient. Prior art catheter retainers are unsatisfactory for a number of reasons. Firstly the retainer may be size dependent. In other words, for catheters of different diameter, a different catheter retainer device may be required. Another disadvantage is that known catheter retainers are often hard and rigid, and therefore uncomfortable to wear. Wearing them may promote lesions or maceration of the skin and so give rise to problems other than that for which the patient is in hospital. Another disadvantage of known catheter retainers is that they are hard to clean. Also, when used with catheters which are of a silicone rubber, a material commonly used for catheters, the catheter tubes are hard to lock in position relative to the retainer because of the slipperyness of the tube. As a result, patients can inadvertently pull catheters out. Yet another disadvantage of known catheter retainers is that the clamping pressure which most of them need to apply tends to collapse the catheter or the drainage tube. In consequence, the efficency of drainage is adversely affected. The invented catheter retainer has a pad (10) of medical grade adhesive capable of attachment to the body of a person who has to use a catheter (C1,C2). The pad (10) carries a member (40) to which is secured a cotton or synthetic fibre thread, or a thread of like material. In use the thread is wound around the catheter (C1,C2) and fastened off by being attached to the member (40). The member (40) is preferably slotted (46) for this purpose. <IMAGE>
