Patent GB-2040977-A (GB)
Title: Photocurable electroconductive coating compositions
IPC: C08F2/50
Filed: 1979-12-07
Abstract: The compositions are formulated with silver powder comprising aggregate or clustered particles, as electroconductivity-imparting agent, in combination with a photocurable vehicle resin and a photosensitizer. Ultraviolet light can penetrate relatively thick layers of the compositions through the interstices of the aggregate silver particles to efficiently cure the deepest parts of the layers. In the prior art, conventional silver-containing coating compositions do not have satisfactory photocurability due to the reflection or absorption of ultraviolet light by the conductive particles. The silver powder of aggregate particles is prepared by heating ordinary silver powder in an atmosphere of non-oxidizing or reducing gas or, more conveniently, by the reduction of silver oxide, formed by the reaction of silver nitrate and sodium hydroxide. with formaldehyde in an aqueous medium, the concentration of the individual reactants and the molar ratio of the reactants being controlled within narrow limits.

Patent GB-799018-A (GB)
Abstract: 799,018. Calculating-apparatus. VEB TRIUMPHATOR-WERK. Aug. 19, 1955, No. 23979/55. Class 106 (1). In a pin-wheel calculating machine, a finger lever 3, by which the drive to the revolution counter is reversed, in changing from addition to subtraction, is locked against inadvertent movement from set position, as soon as the actuating crank 36 is retracted from the neutral position. Normally, with the crank 36 in the neutral position, Fig. 1, the finger lever 3 is adjusted, for addition or subtraction, to one of two terminal positions, and through a toothed segment 9 and gears 16, 18 sets a shaft 17 to the corresponding angular position. In its two set positions the shaft 17 connects the revolution counter for drive in the appropriate sense by means of a swash-plate cam, Fig. 4 (not shown), and aligns a slot 38 or 39 in a locking disc on the shaft 17, with a detent 37 secured to a control rod 33. When the crank 36 is retracted, Fig. 1, it permits the rod 33 to move axially to the right under spring action (not shown) whereby the detent 37 enters the slot 38 or 39 and thereby locks the lever 3 until, at the end of the calculation, the crank is returned to the neutral position and moves the rod 33 to the left to unlock the finger lever 3. The lever 3 is preferably mounted in a slot in the crank bearing block 1 for single-handed operation with the crank, and its terminal positions are determined by leaf-springs 7, 8 co-operating with flats on a portion 6 of the finger lever shaft 5.

Title: Intermittently Feeding Fabric to Pivoted Scale Pan for Forwarding in a Tensionless State to a Cutter
IPC: B65H20/04
Filed: 1981-05-12
Abstract: Fabric (A) is fed via feed rolls (2, 3) to pivoted scale pan (5) only whilst the pivoted arm (9) for the scale pan (5) is pivoted anticlockwise (as shown) with the transmission wheel (7) carried on the pivoted arm connecting the drive wheel (6) with feed rolls (2, 3). The pivoted arm (9) and the scale pan (5) are retained in the upper (i.e. pivoted anticlockwise) position by spring (12) rages acting on one end of the arm and the attraction between magnets (13, 19) carried on arm (9) and pivoted lever (14). As the drive wheel (6) rotates, it pivots lever (14) anticlockwise thereby causing the weight of fabric on scale pan (5) to pivot arm (9) on its lower (i.e. pivoted clockwise) position and disengaging transmission wheel (7) from drive wheel (6) to stop the fabric feed to the pan (5). Continued rotation of drive wheel (6) permits lever (14) and magnet (19) to pivot back to their original positions but the scale pan (5) pivots anticlockwise to its original position only after some fabric has been withdrawn from the scale pan in direction (B). The magnet (13) attached to the end of scale pan arm (9) then holds the scale pan (5) in its upper position during further delivery of fabric to the scale pan (5). The arrangement permits feeding of the fabric in direction (B) to a cutting machine in a tensionless state. <IMAGE>

Title: Windshear detection and warning system
IPC: G01C21/00
Filed: 1982-02-26
Abstract: A windshear detection and warning system based on evaluating the effects of the rate of change of the total reversible energy that resides in a moving aircraft, which energy is the sum of its potential and kinetic energy. The sources of energy change comprise thrust minus drag multiplied by the velocity vector and variations of the wind. When the wind does not vary, the thrust minus drag divided by weight is exactly related to the potential flight path angle of the aircraft which is the sum of actual flight path angle and the acceleration along the flight path. This relationship is disrupted in the presence of wind variations. Means are provided to detect the magnitude of this disruption and use it as a basis for detecting the presence of windshear. <IMAGE>
