Title: Conveyors
IPC: B61B10/04
Filed: 1971-02-19
Abstract: 1313283 Endless chain conveyers G BOWER 4 Feb 1972 [19 Feb 1971] 5036/71 Heading B8A Endless chains 10, 10, each arranged with upper and lower runs (upper run only shown), carry a member 14 having an outwardly spring- urged plunger 18 which normally engages a recess 21 in a member 19 of a load carrier 11 which runs on a pair of rails 13, 13. The arrangement is such that when work needs to be performed on a workpiece on carrier 11, the latter can be stopped while the chains 10, 10, continue their movement. In order that the carriages 11 will not drop off the chain under the force of gravity when passing around the end sprockets (not shown) on to the lower run, each plunger 16 carries a pin 22. This is prevented from inward movement by the side of the sprocket, and so prevents release of the carriages during passage of the carriages around the sprockets.

Title: Process control system
IPC: G05B13/02
Filed: 1969-03-14
Abstract: 1318871 Adaptive control KODAK Ltd 12 June 1970 [14 March 1969] 13696/69 Heading G3R In a process control system in which a process variable is repeatedly sampled, the ratio of an exponentially weighted average of deviations of the variable to an average of the absolute values of the deviations is used as a control term. As shown, a variable of a process 1 is repeatedly sampled and applied to a digital integrator-filter 8 which, by virtue of its feedback, produces an exponentially weighted average of the sampled values. This average is compared in a controller 4 with a desired value so that difference is automatically eliminated by control of the process. The exponentially weighted average of the variable is also compared at 5 with the sampled values of the variable and outputs produced corresponding to any deviations. A ratio, digitally computed at 14, of the modulus, taken at 8, 9, of an exponentially weighted average, taken at 7, of the deviations to an exponentially weighted average, taken at 13, of the modulus, taken at 10,11, of the deviations, is applied through a servo 15 to modify at 16 the gains of integrator 8. In a modification, the ratio, which is derived from deviation signals which are the difference between the sampled values of the variable and a desired value, controls the gain of a PID control system Excessive values of the ratio may be arranged to cause operation of visible or audible alarms or to shut down the process.

Abstract: 1342741 Mine roof supports WE & F DOBSON Ltd 19 Jan 1971 [24 Jan 1970] 3531/70 Heading F1D A mine roof support, Fig. 1, comprising a piston & cylinder both of hollow construction has a valve assembly Fig. 3, which includes a valve 29 for releasing fluid when the pressure in the support increases slowly and a valve 30 which releases fluid when a sudden increase in pressure occurs. A member 96 slides in & out to provide an indication of the pressure in the device. Fluid under pressure passes from the cylinder into a chamber 45 and through a bleed passage 47 in the valve 30 into a chamber 48 which communicates with the valve 29 which is of the "Marshalsea" type. Any sudden pressure increase opens the valve 30 by moving a member 42 to the right against a spring 53. This allows fluid to pass a seat 41 and escape through an orifice 63. Fluid passes through the bleed hole 47 until pressure builds up and the member 42 moves to the left again. Fluid may be manually released by depressing a plunger 60, 61 to unseat a ball valve 49. Fluid is supplied to the support through a non-return ball valve 81. Specification 1332152 is referred to.

The hydrogenation can be carried out in one or more stages with interstage cooling by interstage injection of hydrogen, fresh feed or recycle feed or by indirect heat exchange. The hydrogenation catalyst can comprise 1-50 wt. per cent of an iron group metal, e.g. Ni, or 0À1-10 wt. per cent of a platinum group metal, e.g. Pd, on a support such as chalk, alumina, silica, keiselguhr or sepiolite. The catalyst can be sulphided by thiophenic sulphur in the feed or presulphided with thiophenic or tetrahydrothiophenic sulphur. The separation stages can be flash vaporization, distillation or fractionation. The unsaturated gasoline feed is produced by catalytic or thermol cracking, e.g. in the presence of diluent steam or heated sand, and contains 10-40 wt. per cent cyclopentadiene.

A metering chamber extends from the powder reservoir, and an apparatus is included for compressing the volume of air within the reservoir. A passage extending from the reservoir to the atmosphere is provided to allow air to vent from the powder reservoir, through the metering chamber, and into the atmosphere as the pressure of the volume of air in the powder reservoir is increased by the compressing apparatus. The volume of air thereby causes the powdered medicament to be forced into the metering chamber, and through a selectively openable barrier into an inhaling chamber.
