Title: Method for controlling video and audio of television set
Inventor: REW SANG WON
IPC: H04N5/00
Filed: 1988-06-29
Abstract: A method for controlling video and audio of a television set using a code in such manner that a code is set up in a micom of the television set, which is operated normally only when the code is released by input of a key signal corresponding to the code, to output the video and audio signals. Therefore, it is possible to prevent any person who does not know the code, from driving the television set and children from watching the television broadcast stealthily without noticed by adults. When the code has been set up and the television set is turned on a character generated signal is displayed on the screen to inform the user that the code is set up. The received video and audio signals are then prevented from being output until the required code is keyed in. <IMAGE>

Title: Dispensing device
Inventor: KIRK CHRISTOPHER PETER
IPC: A01K5/02
Filed: 1991-08-21
Abstract: A device (10) for dispensing e.g. food to domestic animals comprises a dish (13) divided into sector-shaped compartments (14) over which a removable cover (50) rotates. The cover (50) has an opening (16) which registers with the compartments (14) in sequence. The cover (50) is rotated by a clock spring at intervals timed by a timer mechanism (25) in turn driven by an electric motor.

Title: Control processor for homing of guided missiles
Inventor: ADAMS THOMAS PHILIP
IPC: F42B15/01
Filed: 1993-07-22
Abstract: In a guided missile 30 having a navigation system directed from launch and a second homing system responsive to a target detector system there is provided a signal processor responsive to target signals to determine values of the angle between the missile direction and the target sightline and the range of the target 13 and from these values to calculate the latest time of change from the navigational system to the homing system to ensure that the missile homes onto the target. The navigational system is an inertial navigational system and the homing system is a proportional navigational system. The handover from the navigational system to the homing phase of the missile trajectory is arranged to occur when the signal processor detects that the modulus of sin  a  /Rk rises to one, where   a  is the look angle of the target from the missile added to the missile incidence in yaw, R is the range of the target, k is a constant defined by <EMI ID=2.1 HE=8 WI=38 LX=1097 LY=1561 TI=UI> <PC>is the maximum design lateral acceleration of the missile and V is the missile velocity. In one arrangement a bias is first introduced by the proportional navigational homing system to increase the modulus of sin  a  /Rk to one when the bias is removed.

Patent GB-2278701-A (GB)
Title: Identifying individual communicating devices
Inventor: ROBERTS-CARLSON ALAN
IPC: G08B25/10
Filed: 1994-03-02
Abstract: The Described invention enables communication between nodes on a common channel signalling system without erroneous identification of one device for another. The transmitting device sends an individual code (the RNC) which is learnt by the receive equipment and stored in non-volatile RAM. This sequence is only necessary on initialisation. Subsequent communications use the RNC known to both devices to distinguish the source of the transmission from another signal of similar structure but different RNC. Many devices (receivers or transmitters) can use the same channel without miss operation of any of the devices. The advantage of this system over the traditional method of transmitting one of several pre-determined codes is that the likelihood of coincident settings is reduced to a negligible level. Additionally the end user of the equipment is not required to set up complex codes or work on small electrical switches, which could present problems for the elderly and infirm. The codes used are secret to the systems using them thus avoiding the necessity of remembering code numbers or the security risk of writing them down. It is a simple matter to change the RNC code, the teach/learn system can be re-activated by a couple of switches, thus setting new codes into the system easily. <IMAGE>
