Abstract: 115,168. Vianello, A. Aug. 20, 1917. Limbs, artificial. - A foot is secured by a gaiter fitted with an extension passing under the heel, a pneumatic cushion being arranged between the foot part and the leg member or between the foot and the stump. In the arrangement shown in Fig. 1, the pneumatic cushion 5 is shaped so that, when inflated, it forms a connexion between the foot part 1 and the leg member 4. Vertical flexible ties 7 limit the longitudinal extension of the cushion and it is strengthened by a leather sleeve 11. Rings 12, 13 are fitted to the parts 1 and 4 to prevent fracture. The gaiter 14 is secured round the ankle by lacing. Cords 16 and 17 serve to adjust the angle of the foot. These cords may be adjustably attached to hooks 18 as shown in Fig. 4. Fig. 4 shows a modified arrangement in which the pneumatic cushion is interposed between the stump 19 and the foot part 1. The cushion may be permanently inflated or fitted with a valve 6. The leg member is formed with projections 22 to give a firm grip to the gaiter 21.

Title: Electronic timepieces with stepping motordriven analogue time displays
IPC: G04C3/14
Filed: 1978-03-30
Abstract: In an electronic watch having a stepping motor, a battery voltage detecting circuit, a rotation detecting circuit for indicating rotation or non-rotation of the stepping motor and a motor driving power control circuit for applying a higher power drive pulse to the motor than a normal drive pulse upon detection of non-rotation, the operation of the rotation detecting circuit is inhibited upon indication of a low battery voltage condition and the motor is driven continuously with the higher power drive pulses for the extent of the battery low voltage condition. In this way, the electronic watch can be operated stably when the battery is at the end of its life and operated with lower power consumption during the time when the battery is operated at full voltage.

Abstract: 1,132,258. Resinous compositions. STAMICARBON N.V. 22 March, 1966 [24 March, 1965], No. 12596/66. Heading C3P. A dispersion of a polyvinyl halide in an ethylene copolymer is made by mixing a powdery polyvinyl halide with the ethylene copolymer at a temperature at which the ethylene copolymer is gelatinized but below that at which the polyvinyl halide is gelatinized. Gelatinization temperature is that below which a powder of the polymer will not form a coherent sheet when milled. The polyvinyl halide is preferably polyvinyl chloride and the ethylene copolymer with vinyl acetate or vinyl benzoate. In order to render the final composition homogeneous the composition is heated above the gelatinization temperature of the polyvinyl halide.

Abstract: 643,675. Pneumatic conveyers. ALLIENNE, V. G. R. May 9, 1947, No. 12630. Convention date, May 11, 1946. [Class 78 (i)] [Also in Groups I and XII] A pneumatic conveyer comprises a container 1 for material provided with an outlet 4 and subjected to repeated shocks to aid the flow therethrough; a fan 14 for conveying the material from the outlet; the container being carried by a closure plate 67 for the fan casing, the plate being fixed to the fan intake pipe 66. Fig. 1. Powder from vibrating container 1 is fed through screen 56 of outlet 3 governed by slide 5 and is swept into the air stream produced by fan 14, which stream enters at 66 and passes out into tube 61 of Fig. 5. The container is suspended by springs 8 and 9 from closure-plate 67, which is formed integrally with air inlet 66 and is adjustably secured (see later) to fan case 14 formed integrally with fan outlet 14a (not shown). Discharge slide 5 is adjusted by nut and screw 6, 7. Figs. 1 and 2. Vibrating means.-On shaft 11 of fan 14 is screwed cam 10 which is formed of nut 51 and nut 52, the nut 52 having an eccentric boring 53 in which are three balls 54 or a single spring-pressed ball, the boring being rounded at its end to contain the balls. Cam 12 is similar to cam 10 and is fixed on the side of the container. Rotation of handle 16 rotates the fan and causes the projecting ball of cam 10 to strike the ball of cam 12 and so shake the container. Figs. 4, 5.

Abstract: 676,726. Valve generating circuits; load coupling arrangements. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 22, 1950 [June 16, 1949], No. 12715/50. Classes 40 (v) and 40 (vi). A radio frequency oscillator comprises a plurality of valves, a transmission line comprising a like plurality of line conductors connected to the respective anodes, each line conductor having embodied in series therewith an adjustable capacitative reactance constituted by electrically conductive concentric sheath and core members which are insulated from each other and relatively movable. The oscillator shown, which is used for high-frequency heating of material placed beneath electrodes 17 and 18 comprises an anode tuning line formed by 2 inch diameter tubes 19 and 20 inside and insulated from 3 inch diameter tubes 9 and 11. The capacity between inner and outer tubes neutralizes the inductance of the anode leads. The line is slightly more than a quarter-wave long and in order to reduce the effect on the oscillator of changes of loading a low inductive shunt may be provided at the voltage node A. The grid circuit comprises a line which is adjusted to be inductive and the screen grid lead inductances 31, 32 are partly neutralized by capacitors 29, 30 so that feed-back occurs to the control grid through the anode-screen-grid capacitance (C1) and screen-grid/control-grid capacitance (C2). This feed-back is regenerative if the reactance of L31 is less than Cl and the total inductance of the control grid circuit is greater than C2. In Fig. 1 (not shown), the anode line is a quarter-wavelength long and in Fig. 3 (not shown), the capacitors are located between two voltage nodes of a line more than a half-wavelength long and serve to reduce the physical length of the line.
