Patent GB-2067500-A (GB)
Title: Conveyor belt
IPC: B65G15/52
Filed: 1981-01-12
Abstract: A conveyor belt of the honeycomb type in which open-work belt sections 2 of cranked or wavey form extend between and intermesh pivotally at transverse rods 1 which pass through apertures in longitudinal components of the belt sections and extend alongside main cross components 3 of the belt sections joined in staggered relationship to the ends of the longitudinal components, is strengthened laterally against distortion by additional cross components 5 which extend between and are joined to the longitudinal components at the opposite sides of the transverse rods to the main cross components. The belt sections are preferably unitary plastics mouldings. As illustrated the belt sections each extend across the full width of the belt and the longitudinal components at the sides of the belt have sockets defined at their free ends which receive the opposite ends of the transverse rods and retain the transverse rods to the belt sections. <IMAGE>

Title: A method of and apparatus for uniformly arranging the nap or pile of a cloth
IPC: D06B21/00
Filed: 1981-01-22
Abstract: A long hair or fibre nap or pile of a cloth is arranged to lie uniformly in a particular direction by applying a treating solution, which may be a dye or pretreatment solution, to at least the nap surface of the cloth to enable the naps easily to lie down, and then brushing or combing the nap surface of the cloth to arrange the fibre or hair nap uniformly. Finally, the cloth is subjected to a wet-heat treatment to set the nap or pile. Suitable apparatus may include a treating solution tank 1 through which a cloth 2 is continuously passed, and a brush roll 7 to brush the hairs or fibres 2' of the cloth to lie uniformly directed along the length of the cloth. The treating solution content of the cloth is controlled by squeeze rolls 9 and 9' before the cloth is passed into a high pressure steamer (not shown) to set the nap. Alternatively, Fig. 2 (not shown), the treating solution is applied in the form of foam (11) by rolls (12, 12') before brushing and, if required, by further rolls (13, 13') after brushing. <IMAGE>

Title: High pressure liquid jetting guns
IPC: B05B3/14
Filed: 1981-03-24
Abstract: In order to increase the area cleaned when a narrow jet of high pressure cleaning liquid is directed along a path extending across a surface (2) to be cleaned, the cleaning jet nozzle (7) is oscillated, for example by piston- cylinder assemblies (8 and 9), so that the jet 12 follows a zig-zag path across the surface (2). The piston-cylinder assemblies (Band 9) may be driven by hydrostatic pressure derived from a pressure intensifier (13) used to supply high pressure cleaning liquid to the gun (1). Alternatively the nozzle (7) may be eccentrically mounted on a rotating member (11). <IMAGE>

Title: Firing of well perforation guns
Inventor: GEORGE FLINT RAYMOND
IPC: E21B43/1185
Filed: 1984-03-30
Abstract: A method and apparatus for actuating a perforating gun by pressure includes a pressure actuated gun firing head (60) disposed on the perforating gun for detonating the shaped charges of the gun to complete an underwater well. The gun is attached (at 86) to a pipe string and located downhole adjacent the formation to be perforated. The pressure actuated firing head includes a housing (62) with a plug (160) and piston (120). The piston has a firing pin (140) adapted for engagement with the initiator (90) of a perforating gun upon reciprocation within the housing. initially, the piston is pressure balanced until the time of actuation.The plug is responsive to fluid pressure of a predetermined magnitude at the time of the actuation of the gun firing head. Upon effecting pressure on the plug, the plug unbalances the piston causing the piston to move downwardly. Upon such movement of the piston, the firing pin engages the initiator to detonate the shaped charges of the perforating gun. Pressure may be effected on the firing head through the pipe string, or the annulus around the pipe string, or both. The firing head includes a plurality of passageways, as well as the plug and piston, arranged in a manner whereby should leakage of well fluids into the firing head inadvertently occur, the apparatus is rendered inoperative and therefore the firing head cannot inadvertently be fired due to the occurrence of unforeseen intervening circumstances. <IMAGE>
