Title: Improvements in apparatus for playing race games
IPC: A63F9/14
Filed: 1928-08-22
Abstract: 321,484. Mitchell, S., and Gibbs, W. B. Aug. 22, 1928. Race games, mechanical.-In a race game apparatus in which racing objects are moved over parallel rails by the competitive action of players, the racing objects take the form of model horses, bulls or steers that are pivotally mounted on trollies and are given a rocking movement by connection to a crank on the drive pulley of the trolly, the arrangement being such that when a certain speed is exceeded, a rider or other figure loosely mounted on the racing object is displaced therefrom. A number of model horses D7, Fig. 4, carrying riders D8, are each supported on a trolly D5 mounted on one of a series of runways E8. The trolly is advanced by a cord C8 that passes round a pulley C9 on the trolly, is connected at one end to the framework, and is wound at the other end around a drum B9, Fig. 1. The drum B9 is manually rotatable by a handle C6 connected to the drum through a clutch comprising radial arms C4 and upstanding projections 07. The body D7 of the horse is pivotally mounted on an arm D6 carried by the trolly, and is caused to oscillate by a lever E2 that is connected to the pivoted forepart E1 of the horse and is actuated through a link E5 from an eccentric pin D1 driven by the pulley C9. The rider D8 is loosely mounted on the horse and is connected thereto by a pivoted link M7. Too rapid rotation of an operating handle C6 causes the corresponding horse to throw its rider, which assumes the position shown in Fig. 6. At the commencement of a race, a lever A, Fig. 1, is operated, and acting through cords A4, levers A2 and flaps A7, raises the drums B9 into operative position, in which position they are maintained by rollers A8 on levers A9 taking beneath the flaps'. The winner is electrically indicated by the closing of a switch L1, L2, Fig. 6, by a projection K9 on the trolly of the horse. Simultaneously, a roller K1 on the trolly depresses a lever K3 that, through cords K6, flaps F7 and other linkwork, rocks the levers A9, Fig. 1, to disengage the clutch members C4, C7 and allow the trollies to return to the starting gate under the action of weights depending from cords. In the event of the leading horse having thrown its rider, the hooked arm of a bell-crank lever F1 on the trolly maintains a lever F3 in upright position so that the lower end F6 of the lever engages and depresses the corresponding flap F7 to cause the return of the horse prior to the actuation of the indicating device and without interfering with the advance of the other horses.

Title: Improvements in and relating to steam turbine plants
IPC: F01K9/00
Filed: 1951-10-16
Abstract: In steam turbine plants wherein part of the water of condensation is cooled and is then sprayed into the exhaust chest of the turbine in order to condense the exhaust steam by direct contact, the casing of the turbine at its discharge side is extended by a conical annular diffuser which penetrates into the exhaust chest.  The cooled condensate is in part sprayed into the exhaust chest through nozzles which direct it in jets against a wall of the diffuser.  In the Fig., the rotor 2 of the turbine with its shaft is supported in bearing 3 surrounded by the wall of exhaust chest 4.  Cool water is sprayed into the exhaust chest through nozzles in boxes 43 and 44; and the condensate and coolant are collected in receptacle 5.  Pump 7 withdraws part of the water from receptacle 5 and forces it through cooler 9.  The remainder of the water is continuously withdrawn from receptacle 5 as feed-water.  The cooled water (from cooler 9) is pumped through conduits 10, 101 and 102 to boxes 43 and 44.  Stuffing box 28 for the rotor shaft is sealed by water of condensation, which is carried along by the shaft and atomized in exhaust chest 4, wherein it furthers the condensation of the exhaust steam. Box 43 is provided with nozzles facing the conical outer wall of diffuser 42. The boundary layer of steam in the diffuser is withdrawn, not only by cooling, but also by suction via circumferential slots 45 in the diffuser walls and via chambers 46 and <PICT:0714705/III/1> 47; both chambers being connected to injector 48 which is operated by water from box 44.  The water discharged by the injector is distributed by perforated partition 49, so that it also serves for condensing exhaust steam from the turbine.

Patent GB-201510-A (GB)
Title: Improved process of manufacturing cellulose esters
IPC: C08B3/10
Filed: 1922-09-06
Abstract: Cellulose esters of organic acids containing more than five atoms of carbon, in particular, the higher fatty acids, are obtained by condensation of cellulose with the acid chloride of the acid in question.  Condensation is facilitated by the addition of an organic base such as pyridine or quinoline; and diluents such as chloroform, carbon tetrachloride, halogen derivatives of acetylene, or benzine may be added.  According to the proportions used monoesters, diesters or triesters of cellulose are formed, the two latter being soluble in the diluents mentioned while the monoesters are insoluble.  The esters are soluble in many organic solvents, and in particular in the aromatic hydrocarbons.  The solutions yield on evaporation colourless and transparent pellicles without the addition of plasticising substances.  In an example cellulose dipalmitate is prepared by treating hydrocellulose with chloroform and pyridine, and palmityl chloride mixed with chloroform is added by degrees. The mixture is heated on a water-bath and then in an autoclave at 100 DEG  C.  The product is dissolved in chloroform and the ester precipitated with alcohol.  Specifications 22029/98, 20977/11, and 20978/11 are referred to.  The Specification, as open to inspection under Sect. 91 (3) (a) refers to the preparation of esters of capric, caproic, caprylic, lauric, myristic and stearic acids, and also of cyclic acids such as naphthenic acid; and it includes the use in the preparation of the esters of the acids themselves or of their anhydrides, and in the latter case melted zinc chloride may be used as a condensing-agent.  This subject-matter does not appear in the Specification as accepted.

IPC: A61F13/15
Filed: 1953-09-02
Abstract: 748,191. Catamenial appliances. LILIA, Ltd. Aug. 24, 1954 [Sept. 2, 1953], No. 24252/53. Class 81(2). The marginal portions along the longitudinal edges of a non-woven textile wrapper of a sanitary towel are coated with a bonding adhesive which is preferably water-insoluble. In the preferred form the rectangular wrapper is coated, by a printing process, with a resinous substance, such as polyvinyl acetate, over the marginal portions ABDC and EFHG. When the wrapper is folded round the pad these portions overlap and provide an impervious outer surface; while, at the same time, the tensile strength of the wrapper is appreciably increased. The strength of the securing tabs may be further increased by extending the bonding adhesive over the ends of the middle portion up to the ends 19, 20 of the pad. The central portion, which covers the upper face of the pad when in use, may further be coated with spaced lines of adhesive in order to improve the tensile strength without appreciably decreasing its permeability.

IPC: G01R31/34
Filed: 1965-06-10
Abstract: 1,089,156. Current-duration meters; power measurement. ROLLS-ROYCE Ltd. June 10, 1965, No.24679/65. Headings G1Q and G1U. The work done by a machine is determined by integrating a current derived from the machine with the object of deriving the state of wear of the machine. In the Figure, the A. C. current in line 12 is the operating current of an electric motor driving a machine tool. In the case of a non-electric machine an equivalent current would be generated by means driven by the machine. This current is transformed, rectified and smoothed before being passed through two integrators 23, 24 such as electrolytic coulometers. Integrator 23 is supplied with a constant current - ensured by a Zener diode 25 or the like - whenever the machine is running. Integrator 24 is supplied with a current representative of the work done by the machine. To ensure this it is arranged (by adjusting resistance R 1 ) that the potential of the junction between resistance R 2  and integrator 24 is the potential of transformer tapping point 16 when the line current is the no-load current of the machine. Integrator 24 thus meters excess of total current over no-load current, and so provides a measure of the total use, i.e. total work done; and integrator 23 provides a measure of total running time.
