Title: Improvements in or relating to hockey sticks
IPC: A63B59/12
Filed: 1963-05-21
Abstract: 972,357. Hockey sticks. M. GARTLAND. May 21, 1963 [July 25, 1962], No. 20167/63. Heading A6D. A hockey stick has a handle 1 spliced to a toe 2 having a striking face formed of a plurality of three or more laminations 3 of timber, plastics material or fibreglass secured together adhesively. During manufacture the laminates are individually coated with adhesive, shaped in a jig and then allowed to set, or they may be bent to the desired shape and then glued together. Alternatively, a sheet of laminated material is bent to a U-shape, divided through the centre of the U, and each half cut into a plurality of toe portions. The toes are formed either with the plane of the laminates perpendicular to the striking face of the hockey stick, or in the case where they are parallel to the striking face, the toes may be cut to shape from a board of laminated sheets. A veneer strip may be applied to the striking face.

Title: Quick closure for steam and gas turbines
IPC: F01D17/14
Filed: 1920-07-09
Abstract: 148,405. R÷der, K. May 13, 1914, [Convention date]. Regulating. - A quickclosing valve a for steam or gas turbines is so controlled that it can only be opened slowly for starting. The valve is opened and held in the open position against a spring c by oil pressure admitted under the piston b by a pipe d, the amount of opening being determined by a cap i secured to a screw spindle e. The cap i closes openings g in the piston connecting the oil inlet d with the oil outlet h. On opening an exit valve in the pipe d, the valve a is quickly closed as the piston b, descending under the pressure of the spring, opens the additional exits g for the oil. Before the valve can be opened by the closure of the oil exit valve in the pipe d, the cap i must be screwed down to close the openings g, the subsequent opening being controlled by the screw e. The Specification as open to inspection under Sect. 91 (3) (a) states that the cap i may unseal the openings g by a sliding or turning motion instead of a lifting motion. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,183,876. Fractionating columns; control. ESSO RESEARCH & ENG. CO. 5 May, 1967 [19 May, 1966], No. 21046/67. Heading BIB. [Also in Division G3] In a system for automatically controlling a refinery process, each of a plurality of signals, dependent in magnitude and sense on deviations of a plurality of process variables from desired values, is applied, after suitable modification, to control more than one of a number of other process variables each of which is thus influenced by a number of signals to restore the first mentioned variables to their desired values. In Fig. 1, crude oil is supplied to a fractionating column 1 at 3, and the top products pass through a condenser 5 to a separator 7 so that fuel gas may be taken off at 9 and the liquid, e.g. gasoline, partly taken off 13 and partly returned as reflux through a conduit 11. Fractions having higher boiling points, e.g. kerosene and diesel oil, are taken off as sidestreams at different levels through conduits 15, 17. The bottom products are taken off at 19. Signals corresponding to the flash and end points of the upper sidestream and the end point of the lower sidestream are respectively derived by units 23, 24, 25. These signals are applied to digital or analogue computer 21 which controls the datum of a controller 27 which stabilises the overhead temperature by control of reflux, and the datum of controllers 29, 31 which stabilise the rates of flow of the sidestreams. Within computer 21 each of the three input signals produces three control signals, one for each of the three controllers, and the computer is programmed so that each of these signals is proportioned to suit the static and/or dynamic characteristics of the control systems which are determined by step function application and frequency response techniques which may involve a model of the process. The three control signals for each controller are then combined and effect control with minimum interference between the control systems. Application to the control of catalytic cracking is referred to.
