Title: Controlling optical modulators
Inventor: MASAKI KATSUMI
IPC: G02F1/01
Filed: 1995-08-31
Abstract: To control the bias voltage of an interference type external optical rnodulator a low frequency generator 3 supplies a signal to an AM modulator 4 which modulator superimposes the low frequency signal on the main modulating signal. Part of the optical signal produced by the modulator is extracted and directed onto a photodiode 7. The low frequency component of the signal generated by the photodiode is then used to control the bias voltage. At the time of starting the power supply 15 the bias voltage is controlled to a predetermined voltage level, preferably ground level, by an integrating circuit comprising a capacitor and a resistor. The initial bias control circuit may alternatively comprise a microprocessor controlled switch, or a discriminating circuit. The initial bias control circuit may further include a temperature sensor such as a thermistor. <IMAGE>

Title: A hydraulic clutch actuator with automatic adjusting device
Inventor: KOPACIN BORIS
IPC: F16D25/08
Filed: 1996-05-01
Abstract: A hydraulic clutch actuator 10 comprises an automatic adjusting device having a ratchet member 30 and a pawl 28. As the clutch wears an end 37 of thrust member 21 pushes flange 35 of pawl disengaging member 30 into contact with shoulder 36 so that when the actuator 10 is next retracted to engage the clutch the member 30 deflects the pawls 28 to disengage teeth 29. This results in spring 38 displacing thrust member 21 and pawls 28 slightly to the left relative to cylinder 14 so that pawls 28 engage the next tooth. The clearance y (see fig 4) created between piston 17 and member 21 is taken up by the admission of additional fluid into chamber 19. The ratchet member 30 is connected to release lever (11, fig 1) via cable 12. Alternatively the actuator 10 may be of an annular form (see figs 5 to 9). Both embodiments may have a self-sealing quick attach coupling to pre-filled cylinder 14 before mounting the actuator 10.

Title: Energy beam curable pressure sensitive adhesive composition and use thereof
Inventor: NOGUCHI HAYATO
IPC: C09J133/06
Filed: 1997-04-21
Abstract: An energy beam curable pressure sensitive adhesive composition is disclosed which comprises at least two energy beam curable copolymers having energy beam polymerizable groups in side chains thereof. This energy beam curable pressure sensitive adhesive composition has satisfactory adhesive strength before irradiation with an energy beam and can be cured by irradiation with an energy beam to a degree such that the amount of adhesive residue remaining on an adherend after peeling is extremely small. Furthermore, the above composition ensures excellent expansibility at the expanding step and excellent recognition at the time of pickup. Still further, the above composition exhibits high work efficiency because of very low pickup strength at the bonding step, irrespective of the execution of the expanding step.
Patent GB-2314403-A (GB)
Title: Expandible lifting devices and valve assemblies
Inventor: RIMINGTON RICHARD MICHAEL
IPC: F16K15/20
Filed: 1997-06-12
Abstract: A valve assembly comprises a rigid mounting (14) and a valve member (15) located in an opening in the mounting. Annular part (16) around the opening provides first valve seat (21) on one side and second valve seat (22) on the other. Valve member (15) comprises first head (23) joined to second head (25) by neck (17) which extends through the opening. Resilient flange (24) engages first seat (21) to form a first valve (12) and resilient flange (26) engages second seat (22) to form second valve (13). Flange (26) has an actuator formation (27) to move at least part of this flange off the second seat. This allows fluid under pressure to flow past flange (26) into the opening for lifting the flange (24) off its seat when fluid pressure in the opening is greater than the fluid pressure at the one side. Formation (27) is tethered to one panel (31) of an extendable or inflatable lifting device so that the valve is used to prevent over-inflation of the lifting device. Multiple valves can be used to provide sequential inflation of a stack of bags of the lifting device.

Title: Power supply switching circuit; battery protection
Inventor: TOMIYORI YUTAKA
IPC: H04M1/00
Filed: 1997-09-12
Abstract: An internal circuit 30, for example in a portable communication equipment 20, can be powered from an internal or detachable battery 1, or from a battery charger connected to terminals (+) and (-), or from an external supply connected to terminals EXT and (-), and a control circuit 7, 8 responds to sensing the presence of the external supply by turning off a MOSFET switch 5 to disconnect the battery 1 thereby preventing charging from the external supply (even if the battery charger is also connected at that time). A battery protection IC 2 also turns off switch 5 when it senses that the battery voltage is above an over-charging level during charging from the battery charger. The protection IC 2 turns off a further MOSFET switch 3 when the circuit 30 is being supplied from the battery 1 and the battery voltage falls below an over-discharge level. Both switches 3 and 5 are turned off if the IC 2 senses excess charge or discharge current to or from the battery 1. Diodes 9 and 12 prevent the battery discharging into a short circuit between terminals EXT and (-) or between terminals (+) and (-).

Title: System and method of electronic mail filtering
Inventor: STOCKWELL EDWARD B
IPC: H04L29/06
Filed: 1997-09-17
Abstract: A modular system and method for filtering electronic mail messages is described. A message is received and processed through a one or more filter flows. Each filter flow includes one or more self-contained nodes which can be interconnected in whatever order is required to enforce a given security policy. The available nodes include filters, modifiers or terminals. Node independence provides a policy-neutral environment for constructing filter flows, and components are easily rearranged to change policy. A filter flow may be as simple as forwarding the mail to the intended recipient, or may perform one or more checks where it decides whether to forward, reject, ram (or some combination thereof) the message. Certain node types are also able to append information on to a mail message, while others are able to modify certain parts of a mail message. Certain node types are able to generate audit or log messages in concert with processing a mail message. A graphical user interface creates and maintains the filter flows, Figs. 8A, 8B, (not shown).

Title: Vacuum cleaner with wheel fixing apparatus
Inventor: LEE NAM HO
IPC: B60B37/10
Filed: 1997-12-04
Abstract: A vacuum cleaner has a hollow first fixing member (10) formed on an external surface of the body (112). A second fixing member (20) is detachably assembled with the first fixing member (10). The first and the second fixing members (10,20) carry respective ribs (12,22) which together form a circular-shaped supporting rib part when the first and the second fixing members are assembled with each other. A rotational shaft (124) of a wheel (120) is received in the supporting rib part (12,22). With this arrangement it is no longer necessary to form a bore in the body (112) to support the wheel shaft (124), and hence a path through which air can be discharged is no longer defined. Furthermore, as the shaft (124) does not extend into the body (112), it becomes possible to accommodate components in the body.
