Abstract: 1323740 Luminescent materials WESTING- HOUSE ELECTRIC CORP 30 Dec 1970 [14 Jan 1970] 61768/70 Heading C4S A luminescent coating composition comprises divalent Eu activated Sr chlorophosphate phosphor and Sb 2 O 3  and/or a compound which decomposes to the oxide on heating. The composition is prepared by forming a suspension of the phosphor in NH 3  and adding a solution of Sb 2 O 3 , in HCl whereby insoluble SbOCl is formed and is precipitated mixed with the phosphor. The dried suspension in an ethyl cellulose paint is applied to a fluorescent lamp envelope which is heated to 550 to 675‹ C to decompose the SbOCl and remove organic binder. Alternatively the phosphor mixed with Sb 2 O 3  can be added to the paint. The Sb 2 O 3  is 0À05 to several % preferably 0À25 to 1À6% by weight of the phosphor. The gram atom ratio of Eu to total metal is 3À5 x 10<SP>-3</SP> to 3À5 x 10<SP>-2</SP>.

Patent GB-2031438-A (GB)
Title: Fabric-reinforced ion exchange membranes
IPC: C08J5/22
Filed: 1978-09-27
Abstract: The production of chlorine and alkali metal hydroxide by the electrolysis of brines employs cells, which commonly incorporate ion- permselective membranes. The invention concerns improved membranes which are based upon films of sulphonyl-group containing fluorocarbon polymers having ion-exchange properties. These improved membranes have fabric reinforcement applied to a surface of the polymer film and, after the fabric reinforcement has been applied by the use of heat and pressure, the fabric-reinforced side is treated, to a depth of at least 10 microns, with a primary amine, a secondary amine or a mixture thereof, so as to aminate a majority of the polymer sulphonyl groups. This procedure avoids the polymer degradation associated with conventional lamination after sulphonamide formation, and also improves fabric incorporation.

Patent GB-2044854-A (GB)
Title: Brake actuator particularly for agricultural trailers
IPC: B60T17/08
Filed: 1979-02-28
Abstract: The actuator includes a ram (a) slidable in a cylinder and urged in the brake applying direction by a compression spring (d) disposed between fixed and slidable collars on the cylinder, the slidable collar being movable by rods (g) attached to the ram (a). Release of the brakes is effected by operating the normal hydraulic control valve to supply hydraulic pressure (b) to the space between the ram and the cylinder base (k) thereby to extend the rod (a). A hole (h) bored into the working face of the ram accommodates an oil return pipe (j) attached to the base (k) so that as the ram extends it moves along the return pipe until before the ram is fully extended a slot (l) in the pipe (i) is exposed allowing oil to return to reservoir. Thus the brakes are kept in an off position by a 'straight through' flow of oil. Cessation of pressure through control valve or pipe breakage causes the brakes to be applied by the pressure of spring (d) retracting the ram and forcing oil out of the cylinder. <IMAGE>

Patent GB-2050005-A (GB)
Title: Improvements in or relating to electronic timepieces
IPC: G04C3/14
Filed: 1979-05-29
Abstract: A stepping motor driven analog electronic timepiece (Fig. 17) includes a control arrangement whereby the width (e.g. 3.9 m secs) of normal drive pulses is automatically changed in incremental or decremental steps (e.g. of 0.5 m secs) to the minimum value capable of maintaining rotation. If a non-rotatable condition is detected by a detecting circuit 95 (as described with reference to Fig. 9 or Fig. 12), a correction pulse (e.g. of 7.8 m secs) is applied to the motor winding to product rotation. Immediately thereafter, a brief pulse is applied in the opposite direction to the correction pulse to demagnetize the stator before the next normal drive pulse. The control circuit 93 ensures that the width of the next normal drive pulse after a correction pulse, will be one increment greater than the drive pulse immediately before the correction pulse and which failed to produce rotation. <IMAGE>
