Title: Provision of runtime bindings for software objects with polymorphic types.
Inventor: SADLER JOHN
IPC: G06F9/42
Filed: 2009-05-28
Abstract: Runtime bindings provide code for manipulating the attributes and invoking software objects according to their dynamic type in multiple run time environments. A registry of class types for software objects is established (51). Each class type is linked to a hierarchy of bindings rooted at the binding for that class type (52) with descendent bindings (53) in the hierarchy relating to more specific sub-classes. At run-time a pointer to an object (1) is received, the pointer being used to look up the registry to determine the location in the hierarchy of bindings at which to make an initial query for the most specific sub-class compatible with the dynamic type of the object. Subsequently, beginning at the determined location in the hierarchy of bindings, the most specific sub-class compatible with the dynamic type of the object is determined, and a run-time binding based on the most specific sub-class identified can be selected. In a further embodiment a method of generating the binding is provided comprises generating binding source code and compiling it with mapping code describing the hierarchy to produce the binding and a support registry.

Title: Improvements in or relating to electric indicating or control systems
IPC: G08C19/06
Filed: 1937-04-08
Abstract: 493,457. Electric correspondence control systems. WALLACE & TIERNAN PRODUCTS, Inc. April 8, 1937, No. 10033. Convention date, April 17, 1936. [Class 40 (i)] In a system for indicating or reproducing the movements of a member, the movements are reproduced .by a shadedpole induction motor operated through a valve amplifier. As shown the system is arranged to repeat the movements of a float 11 on an indicator 10, the float controlling the inductance of the arms 12 of an impedance bridge, whilst the output voltage from the other arms 13 is applied through a valve amplifier 21 to a transformer which supplies the shaded-pole motor 23. The motor is excited by a winding 34 and the shading coils 35 .. 38 are connected in series with the secondary winding 32. Normally when no voltage is induced in the winding 32, the induced voltages in the pairs of shading coils 35, 36 and 37, 38 are in opposition and the motor is stationary, but when the balance of the bridge is disturbed by the float 11 the secondary voltage causes current flow in the shading coils in one or other direction to produce rotation of the motor which operates the indicator 10 and through linkage with the core 15 re-balances the bridge. In a modification each pair of shading coils is supplied by a separate secondary winding. Specification 34855/98, [Class 118], is referred to.

Abstract: 475,720. Calculating - apparatus. LEVKOVITSCH, P. GOUDIME-, and SIMMONDS DEVELOPMENT CORPORATION, Ltd. April 9, 1937, No. 10171. [Class 106 (i)] A device for use in correcting the readings of altimeters and air-speed indicators for varying temperature and pressure conditions comprises relatively movable members and pointers with logarithmic scales whereby the corrected height or pressure may be read directly as the product of the absolute temperature at the indicated height or pressure and a function of the said height or pressure. A combined air speed and height computer is shown in Fig. 1, and comprises two relatively movable discs 1, 2, and a pair of plates 13, 14, Figs. 4 and 5, constituting pointers arranged between the discs. The disc 1 is formed with windows 6, 7, 8, and has inscribed thereon scales 9, 10, for temperature and barometric pressure respectively ; the lower disc 2 has marked thereon scales 3, 4, 5, for indicated height, corrected height, and air speed respectively. The plate 13 is formed with pointers 11, 15, 16 and has a set screw 11<1> for clamping it to the disc 1 ; the plate 14 has a single pointer 12 with a set screw 12<1> and carries a scale 17 for indicated height. In operation the temperature is set by means of the pointer 11 and the ground barometric pressure by means of the pointer 12 ; the discs are then rotated until the indicated height on scale 3 appears against a fixed mask 18 on the disc 1. The corrected height is then read off against pointer 16 on scale 4. If the indicated air speed on scale 5 is set against the indicated height on scale 17, the corrected air speed may be read off against the pointer 15. A modified form of height and air speed computer is described in which separate temperature settings are applied for computing the corrected height and air speed.

Abstract: 351,963. Brake shoes acting on drums. KING, A., Fern Cottage, Norton- St.-Philip, Bath, Somerset. April 1, 1930, No. 10271. [Class 103 (i).] In clutch or brake mechanism for motor vehicles, line and countershafts, &c. of the type comprising two opposed spring-controlled friction segments having radial extensions with substantially U- shaped overlapping ends and an actuating-member slidable into the opening between them to disengage the segments from a coacting drum &c., as described in Specification 20033/02, [Class 80, Mechanism &c.], the segments slide on studs or the like carried by one clutch or brake element and the actuating-member acts by wedge-surfaces directly on the segments, e.g., through rollers. As applied to brakes, the member carrying the shoes is mounted on a stationary shaft or part, and the brake pedal or lever may be held in the " off " position, against engaging-springs, by a spring-controlled detent. As applied to clutches segmental shoes 13, Figs. 1 and 3, are pressed by adjustable springs 28 into contact with a driving-drum 10 and have. extensions 15 with legs 16 in sliding contact. The driving shaft 11 bears in the hollow driven shaft 12, beyond which the legs 16 are provided with inturned parts 17 receiving the spindles 19 of rollers 18. The shoes slide between a retaining-ring 24 and a carrier 22 welded &c. to the shaft 12 and have slotted engagement 23 with studs 21 secured to the carrier. The shoes are disengaged by the coned end of a pedal-actuated sleeve 31 coacting with the rollers. In a modification, Fig. 4 (not shown), the carrier 22 is splined to a coned end of the driven shaft, which is solid and does not engage the driving shaft, the rollers contacting with reversely-sloped extensions of the actuating-sleeve so as to tighten the carrier on its shaft. In another form, Fig. 5 (not shown), the studs 21 are screwed into a driving- flywheel &c., the drum being carried by the driven shaft and the rollers 18 acted on by a pointed rod, which slides in a bore of the driven shaft and is connected to the actuating-sleeve by a transverse key. Fig. 6 shows a modification in which the pointed rod 39 carries a disc 44 connected by external rods 43 to the sleeve 31. In a further modification, Figs. 7, 8 and 9 (not shown), the carrier, which has four studs 21, extends from a sleeve on the driving-shaft and the shoes engage a loose driven pulley. In this form, the rollers 18 are long and the legs 16 sufficiently separated to allow radial withdrawal of the shoes, after removal of the rollers. In the constructions shown, the springs 28 surround screwed rods 26 secured to one shoe and slidable in the other, but each shoe may have one rod and an aperture to receive the other rod.

Abstract: 891,476. Friction Clutches. HINDMARCH, T. July 24, 1959 [Aug. 29, 1958], No. 10371/59. Divided out of 891,475. Class 80 (2). In a friction clutch for marine, locomotive and industrial transmissions wherein bronze inner members 1 splined on a shaft 11 are axially expanded by fluid pressure in a telescopic oil chamber 6 to frictionally engage an axially fixed steel outer member 5 which may have gear teeth 12 as shown, the members 1, 5 respectively of higher and lower coefficients of thermal expansion have corresponding concentric rings of interengaging conical surfaces 4 respectively facing towards and away from their common axis, the remaining non-engaging surfaces 3 being relieved to prevent contact. To ensure engagement of all the surfaces 4 at full working temperature, the said surfaces are arranged, when cold, to have clearances progressively diminishing with distance from the axis, the difference in thermal expansion between the members 1, 5 thereby effecting, with temperature rise, spreading of contact inwards from the outermost surfaces 4 which alone engage when cold. Contact spread is assisted by flexure of the inner members 1. This arrangement of progressively diminishing clearances may be combined with that described in Specification 891,475 wherein the cone angles of the interengaging surfaces are increased with their distance from their common axis. There is no wedging action and copious lubrication is maintained between engaging surfaces. The clutch is disengaged by pressurizing chambers 7.
