Patent GB-774046-A (GB)
Abstract: 774,046. Cathode materials and processing. SOC. ANON POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARESETABLISSEMENTS CLAUDE-PAZ & SILVA. May 19, 1955 [May 20, 1954], No. 14471/55. Class 39(1). A hollow electrode made of at least two parts joined together has an enamel coating over the join, to prevent emissive material within the electrode from escaping through the join. The electrode shown, of the type used in low pressure mercury vapour tubes, is formed of a cylindrical sleeve 5 nested into a closure cup 3. The sleeve itself is made by rolling a flat plate into a cylinder, and crimping the edges together. Thus there are two joins through which emissive material, subsequently placed inside the electrode and melted at about 500‹C., might escape. This is prevented by melting an enamel coating over the joins, or even over the whole outer surface. Calcium borate is suitable, and may be applied in powder form, or in solution, or by dipping, and subsequently fired.

Title: Solar tracking apparatus
IPC: F24S50/20
Filed: 1978-11-10
Abstract: Solar tracking apparatus utilizes received solar energy to effect tracking movements, the apparatus comprising a paraboloid mirror, pivotally mounted for tracking the sun. The drive means includes solid heat expansible members, disposed relative to the mirror so as to receive different amounts of solar radiation when the mirror is misaligned with the sun so as to produce a differential expansion therein and the resultant mechanical force tends to correct the misalignment. The tracking action is disabled by an excess heat cut-out to prevent thermal overload. Photo transducers may be included and are arranged to be cooled by the transfer fluid. The parabolic mirror has a flexible reflective sheet on a framework.

Title: Driving looms
IPC: D03D51/06
Filed: 1979-08-31
Abstract: An arrangement in a weaving loom for stopping the loom in the event of weft thread breakage comprises actuating means (1) which provides a signal in the absence of a weft thread in a shed formed by the loom. This signal results in the disengagement of a first clutch (10), which disconnects the loom drive from a shedding mechanism (13), and engagement of a second clutch 11, which connects a motor (5) to the shedding mechanism (13) to drive the mechanism in the reverse direction to re-open the unfilled shed. Both of these operations are initiated by the rocking of a lever (9) by a cam (8) which is rotated by the motor (5) when the actuating means (1) produces a signal. The lever (9) also actuates a weft insertion mechanism (27) which inserts a fresh weft thread into the re-opened unfilled shed. <IMAGE>
