Title: Method and apparatus for welding a length of tube on to a pipeline
Inventor: ANCENYS JEAN-CLAUSE
IPC: F16L1/26
Filed: 1989-01-12
Abstract: The present invention provides a method and apparatus for welding a length of tube (3) onto a pipeline (1) in which the weld zone of the pipeline is preheated in order to obtain a welding temperature favourable to the welding operation by placing an annular inductor (4) around the welding zone (7) and around the length (3). The annular inductor comprises one or more layers of conductors fed with medium frequency current, the inductor (4) being disposed on an insulating mat (5) put into contact with the wall of the pipeline (1). Shielding (6) is disposed around the length of tube (3), the shielding being displaceable lengthwise on the length (3) enabling it to be positioned at a variable distance from the welding zone (7) in order to reduce the temperature in the length of tube (3). This counters the tube's inherent tendency to overheating due to its substantially coaxial position within the inductor (4) due to the fact that no fluid flow takes place inside the length of tube (3) which could reduce the temperature of the length. The invention is applicable to off-shore underwater work. <IMAGE>

Patent GB-2230663-A (GB)
Title: Photographic flash apparatus
Inventor: KOBAYASHI TAKEO
IPC: G03B7/16
Filed: 1990-03-15
Abstract: To prevent damage due to heat generated by frequent flashings, recharging of a main flash capacitor C1 is inhibited for a predetermined period following a previous charging. The inhibit period is made dependent on how frequently the flash lamp has been flashed, the period being incremented each time the capacitor C1 is charged and decremented if the time between charging operations exceeds 4 seconds. A charging operation is stopped if the voltage VF on capacitor C1 does not reach a predetermined level within a predetermined time, both the level and time being dependent on operation conditions of the associated camera. The voltage VF on capacitor C1 is determined from the voltage - dependent pulse width of a pulse generator C3, TR3, TR4 which will not function until VF has reached 270V, sufficient to turn on a neon lamp via which capacitor C3 is charged from capacitor C1. The flash apparatus is controlled by a CPU which also controls zoom lens and film wind motors, a status display and indicators, exposure mode, automatic focus and automatic exposure. Exposure is controlled in dependence on the voltage on capacitor C1.

Title: Orthogonal slot flat microwave antenna for dual polarization
Inventor: COMMAULT YVES
IPC: H01Q21/24
Filed: 1991-06-20
Abstract: The antenna comprises a first and a second conductive plate (1 and 2) placed one above the other and separated by a dielectric volume, and two excitation striplines (3 and 4). The first conductive plate (1) has, formed in it, the pair of orthogonal radiating slots (6 and 7) disposed to form a cross. The second conductive plate (2) plays the role of a reflector. The central conductors of the excitation striplines (3 and 4) pass in a single plane between the first and second conductive plates (1 and 2) and intersect at a point of intersection in the center of the cross formed by the pair of orthogonal radiating slots (6 and 7). The fact that the central conductors of the excitation striplines (3 and 4) are in a single plane and not in two separate parallel planes, allows to simplify the structure of the antenna and to reduce its thickness. The length of stripline beyond the intersection point is arranged to achieve low cross coupling between the two striplines. <IMAGE>
