Patent FR-948945-A (FR)
IPC: F41G7/00
Filed: 1947-06-14
Granted: 1949-08-16
Abstract: 587,438. Automatic steering control systems. BENDIX AVIATION CORPORATION. June 4, 1942, No. 7647. Convention date, May 15, 1941. [Class 38 (iv)] [Also in Group XXXVIII] A device for ascertaining the direction of a source of sound comprises directional and non-directional microphones, and means energized by the microphones to turn the support of the device in that direction. The device may be used to steer a projectile towards a source of sound such as an aeroplane.. In the arrangement shown a directional microphone 10, which may be of the ribbon type, is carried by a vertical shaft 20 that rotates a pointer 31 over a scale 32 and is also geared to a shaft 23. A non-directional microphone 27 is mounted above and close to the microphone 10. The output of the microphone 10 is connected through an amplifier 15 to windings on two opposite poles 18 of an indication motor 17, and the microphone 27 is similarly connected to poles 19 which are at right angles to the poles 18. The rotor 26 of this motor is geared to the shaft 23 and is thus able to rotate the microphone 10 about its vertical axis. The difference in the outputs from the microphones causes the microphone 10 to be turned by the shaft 23 until it faces the direction of the sound, which also will be indicated by the pointer 31. The same result can be obtained by using three stationary directional microphones instead of the single movable directional microphone 10. The three microphones are arranged one above the other and closely adjacent, the ribbon of each being displaced 120 degrees with respect' to the others. The microphones are separately connected to three pole-windings of an indication motor the rotor of which having a winding that is connected to opposite polewindings of another motor, similar to the motor 17. The other windings of this motor are connected to a non-directional microphone. The rotors of the two motors are geared to one another and to an indicating pointer. In each case, the arrangement may be mounted on an aircraft to give the pilot some indication of the position of an enemy aircraft. A similar arrangement may be used for steering a selfsteering glider-projectile which, when dropped from an aeroplane in the path of approaching enemy aircraft, glides downwards and is steered towards the enemy aircraft by the noise of the engine. The glider-projectile may be provided with a suitable relay which explodes it when the noise of the target aircraft reaches a predetermined volume. Means may be provided also for exploding the projectile before it reaches the ground should it miss its target.

Patent GB-2348694-A (GB)
Title: Cryogenic coolers
Inventor: MIRMOBIN PARSA
IPC: F25B9/14
Filed: 2000-03-28
Abstract: Cryogenic systems commonly utilise a closed-loop thermodynamic cycle such as the Gifford-McMahon cycle, in which a high pressure working fluid (commonly helium gas) is admitted into and withdrawn from a working volume (4) of a cylinder during the cycle, and the size of the working volume is varied by means of a displacer (7) reciprocating within the cylinder. The system also includes a regenerator (10: a heat exchanger, usually within the displacer 7) through which the gas flows in alternate directions at different times in the cycle. To minimize the loss of power of the system associated with the gas increase in the regenerator/working volume and/or with the loss of gas one or more additional valves (16/17, 19/20] are contained within the displacer (7) to control the flow of gas through the heat exchanger (10) at the appropriate periods of the displacer cycle. The valves may be in the form of floating plates closed by a spring. A pressure relief valve may modify the operation of valve (19/20). The valves may be electromagnetically-actuated valves.

Title: Universal indicating lamp installation / removal tool
Inventor: TALBOT WARREN ANTHONY
IPC: H01K3/32
Filed: 2000-05-25
Abstract: The tool (known as the 'changerer') is designed to install and remove indicating lamps of all shapes and sizes. The tool consists of a pen-like body (1) with a rotating shaft (2), a 'T' shaped elastic band (4), a rotating finger grip (5) which is attached to the rotating shaft (5) and a protective cap (6). The method of operation is:-<BR> The 'T' shaped band is threaded through the fixed shaft (3) until the shoulder of the 'T' is hard up against the slot. The band (4) is then threaded through the slot in the rotating shaft (2) which then forms a loop in the elastic band. (See figure 3.) This loop is then pushed on to the lamp to be removed or installed. (See figure 3.) The rotating finger grip is then turned clockwise until sufficient torque is achieved to enable the lamp to be gripped by the band and installed or removed. Turning the rotating finger grip 5 will then release the lamp.

Title: Detection of an email virus by adding a trap address to email address lists
Inventor: MORRIS ROBERT
IPC: G06Q10/00
Filed: 2000-06-28
Abstract: The address of a virus notification program on a email server is added to the address book of all computers covered by the detection service. When an email virus is active, it propagates by sending further emails to all addresses in the infected computer's email address book. If the virus notification program receives an email at this address then it concludes that a virus is active and warns the user or administrator. The server may halt the transmission of all email messages from the local network. Outgoing messages may be queued for a short time so that their transmission can be halted when a virus is detected. The virus notification program may be located at an internet site.

Title: Wavelength router for optical bidirectional transmission of data
Inventor: SCHUNK NIKOLAUS
IPC: H04B10/00
Filed: 1999-05-18
Abstract: A wavelength router for optical bidirectional transmission of data, containing a plurality of add/drop filters (1) for signal injection to form a wavelength multiplex and for selective extraction of signals in order to break said multiplex down. A wavelength router of this kind represents a considerable amount of complexity in terms of circuitry; especially since only one respective signal of a subscriber can be injected or extracted using an add/drop filter. The aim of the invention is to reduce overall circuit complexity in said wavelength router. Injection and extraction are carried out respectively in the same add/drop filter (1) for a subscriber. In order to avoid crosstalk, extraction occurs at a wavelength of   g  <SB>i</SB> and injection occurs at a down-shifted wavelength   g  <SB>i</SB>. Preferably, the wavelength difference between injection and extraction corresponds to a wavelength distance of the wavelength multiplex.

Title: Single disc clamp nut for disc clamping in a disc drive
Inventor: WEST TERENCE HAYDEN
IPC: G11B17/038
Filed: 2000-04-20
Abstract: An apparatus and method for securing an information storage disc within a disc drive incorporates a spindle motor, a rotatable spindle hub, a disc clamp and a disc clamp nut. The disc clamp is positioned on the rotatable spindle hub to clamp the information storage disc to the spindle motor. The disc clamp defines a middle annular raised portion for accepting a predetermined pre-load force to compress the disc clamp down onto the information storage disc. The pre-load force is perpendicular to the disc clamp, and is applied symmetrically around a spindle motor axis of rotation. The disc clamp nut includes a flat engagement surface that secures the pre-loaded disc clamp to the hub. The pre-load force is released once the disc clamp nut is positioned so as to secure the disc clamp to the hub of the disc drive spindle motor. A series of substantially parallel engagement surfaces on the disc clamp nut, disc clamp and hub ensure that the pre-load force is uniformly applied to the information storage disc. The engagement surfaces between the disc clamp, hub and information storage disc can also be co-planar.
