Patent GB-2062678-A (GB)
Title: Current Contact for Electrolytic Cell Electrode
IPC: C25C7/02
Filed: 1979-11-02
Abstract: In electrolytic cells, where the electrolyte is pumped through the cell causing a pressure differential with respect to atmospheric pressure, and the electrodes are totally immersed in the electrolyte, any material discontinuity in the immersed portion of an electrode forms a point where corrosion may be initiated. Such a condition occurs where the connection to the anode is made within the cell. To avoid such a discontinuity an electrode is provided where the contact is formed from the same body of material as, and continuous with, the electrode, the contact extending through a wall of the cell so as to present no material discontinuity within the electrolyte. In a preferred form the electrode is a sheet formed into a hollow cylinder and having a radially extending tongue to form the contact. The cylinder is resiliently radially compressible for insertion into the cell.

Title: Target-trucking interception control systems
Inventor: WEIKERT HEINRICH
IPC: F41G5/08
Filed: 1979-12-31
Abstract: Target-tracking interception control systems, e.g. fire control for an anti-aircraft defence system, uses a digital computer which is continuously supplied with the flying object position data derived from echo signals of a tracking radar and is used to calculate the lead-angle for the projectile launch on the basis of flight time, target data and the ballistics of the projectile. The lead-angle is obtained by solving a specified system of equations for numerous values simultaneously in a plurality of parallel calculating channels for differing values of the variable projectile flight time.
Patent GB-2073443-A (GB)
Title: Control of spot weld quality by infrared thermal sensing
IPC: B23K11/25
Filed: 1980-04-02
Abstract: Control of spot weld quality is effected by observing the progress of heat generation within the weld and initiating automatic corrective action if the heating rate is initially too high or too low. A flexible optical fiber bundle has one end located in the welding tip and the other end optically coupled to an infrared detector. Due to the excellent thermal conductivity of the copper material of the welding tip, the infrared detector produces an output signal proportional to the weld temperature. This signal is sampled and compared with a previously-recorded signal, corresponding to the heating rate that produced a good spot weld in the material being welded, to generate a control signal for controlling the welding power of the spot welder during each weld.

Patent GB-2092547-A (GB)
Title: Ambulance patient's (roller shutter) footguard
IPC: A61G3/06
Filed: 1981-01-22
Abstract: The footguard is used on Ambulances fitted with tail-lifts, such as those used by Social Services to carry wheelchair patients. It covers completely, the gap which normally exists, between the rear of the ambulance and the ground, and prevents the patient's feet from protruding into the gap, and subsequently suffering injury, as the tail-lift platform ascends, and passes the level of the rear underside of the ambulance. The footguard is a roller shutter housed in the rear extension box of the ambulance chassis, and covering the full width of the tail-lift platform. The shutter is fitted with a channel section bottom rail which protrudes from the bottom edge of the box. An opposing channel is secured to the back edge of the tail lift platform, and as the platform descends and ascends, the two channels mate up, therefore pulling the shutter out of and into the box, and completely covering the gap between chassis and ground during the descent and ascent of the platform, consequently protecting the patient's feet from injury.   <IMAGE>
