Title: Combined closure and pouring device for a container
IPC: A47G19/12
Filed: 1975-10-14
Abstract: 1516415 Dispensing closures HO HOI 1 Oct 1976 [14 Oct 1975] 42040/75 Heading B8T A combined closure and pouring device 10 comprises a pouring opening 15, an intermediate wall 16 having an aperture 18 of smaller area than opening 15 and in alignment therewith and a manually operated spring-loaded plunger 19 which can be moved against the action of spring 22 to obturate aperture 18. Device 10 is particularly intended for use when dispensing relatively viscous substances such as syrup, the substance exiting from container 14 when in the pouring position, Fig. 3 (not shown), via aperture 18 and through opening 15 without contact with the latter. When the dispensing operation is to be terminated, aperture 18 is obturated and to facilitate a clean cut-off, end 20 of plunger 19 is provided with a sharp-edged annulus. Any substance remaining in chamber 17 after dispensing returns to container 14 via one-way valve 27. Pouring opening 15 is normally closed by a flap 23 connected to a weight 26 eccentrically pivoted for rotation at 24. In the dispensing position flap 23 automatically clears opening 15. As shown, device 10 is screw. threadedly engaged with container 14 and is provided with a handle 28. Alternatively the handle may be a container 14 and device 10 may be otherwise connected thereto, e.g. by means of a bayonet connection.

A watch regulator 5 is angularly adjustable by a drive screw 8 which engages a toothed sector 7 of the regulator, the drive screw being mounted in a movable stud holder 1. The stud holder has an annular body 1a which is frictionally fitted on a portion 2 of a cock. The outer end of a hair spring 4 is clamped in the stud holder which is rotatable about the portion 2 to the desired position. The regulator 5 has an annular portion which is frictionally mounted on the body 1a of the stud holder, the regulator including a key 6 for determining the active length of the hair spring. Adjustment of the position of the regulator is effected by inserting a screw driver, &c. in a slot formed by a sleeve 9 on a rod 8a of the screw. In a modification, the drive screw is mounted approximately radially with respect to the annular portion of the regulator.

Title: Device for dissolving a solid in a flowing liquid to a desired concentration

Abstract: 1,003,213. Mixing solids with flowing liquids. P. SCHMITT. Nov. 28, 1961 [Nov. 29, 1960 ; June 19, 1961], No. 42508/61. Heading B1C. A device for dissolving a solid to a desired concentration in a flowing liquid comprises a container having a cylindrical transparent chamber A in which the solid rests on a perforated bottom 1. The liquid flows in at 3, passes through the orifices 5 and up through the solid, the solution thus formed passing through the orifices 6 and out of the device at 4. When the flow is interrupted, the liquid which may be left in the apparatus or flow into it due to variations of mains pressure may dissolve a greater quantity of solid than the corresponding volume would in passing through the chamber ; a funnel-shaped draining device 2 is therefore provided to conduct such concentrated solution into the collecting chamber B. Solution from the chamber B may be added gradually to the outflow at 4 by means of the valve 10, or by means of the valve 9 be swept out at 7 in a stream of greater concentration than the normal outflow. In modifications, Figs. 2A and 2B (not shown), the liquid passes down through the solid.

Abstract: 1,141,564. Controlling reactors. SOC. ANGLO-BELGE VULCAIN, S.A. 29 Sept., 1966 [19 Oct., 1965], No. 43591/66. Heading G6C. A nuclear reactor having a coolant-moderator fluid, has neutron absorbing control rods which are positioned by the regulation of the fluid pressure on the rods. Each rod is coupled to a damping cylinder and piston. Rapid insertion of the rod into the core is facilitated by a oneway port in the cylinder. Each rod is freely located in a vertical channel, open at the base to the medium pressure zone in the fluid circuit and is coupled, through a valve at the channel upper end to either high or low pressure points. Adjustment of the valve urges the rod rapidly down the channel, into the core or permits a slower, damped motion upwards from the core. The coolant-moderator is circulated upwards through the core by impellers mounted in the pressure vessel, and downwards over the inside surface of the vessel. Heat exchangers surround the core.

Hot gas is fed from heater 20 via line 21 and throttle valve 30 in inlets 26, 27, 28. The portion of chamber 12 from the point 1 where the rotor gets closest to casing 11 to the point 2 defined by the inlet 28 defines a phase A' which corresponds to the isothermal expansion phase in the Carnot cycle. The hot gas continues to expand between points 2 and 3 defining a phase B corresponding to the adiabatic expansion in the Carnot cycle. Between points 3 and 4 the gas is compressed while giving up heat in passages 31, 33 having cooling fins. This corresponds to the isothermal compression in the Carnot cycle. Finally, the gas is further compressed, defining a phase D corresponding to the adiabatic compression of the Carnot cycle. The gas is discharged through duct 16 and check valve 41 to heater 20 for reheating and distribution to inlets 26, 27, 28. A gaseous fuel supply 35 provides propane or butane for the heater and also supplies make up gas to line 18.

A manipulator, particularly for a forging press, has its peel shaft 11 resiliently biased axially into a neutral position under the control of a dashpot 25, 26. The peel shaft 11 is slidably mounted in a sleeve 12 integral with a ball 13 supported in a pivot block 14. The latter moves continuously during the forging operation whilst the peel is stopped intermittently when the forging tools engage the workpiece. Upon its release the spring 15 restores the peel shaft 11 to its neutral position under control of two dashpots 25. The dashpot pistons 26 are connected by rods 24 to the sleeve 12 and the cylinders 25 are carried by the peel shaft 11. In each cylinder a variable restricted flow passage 30, Fig. 2 (not shown), connects opposite sides of the piston 26 whilst unrestricted passages 33, 34 are closed by the piston 26 in its neutral position. After a certain movement of the piston in its cylinder, the ports 35, 37 are uncovered to permit free flow of fluid. During the restoring movement of the peel shaft to neutral position, the pistons 26 close the ports 35, 37, whereby the restricted flow of fluid cushions the movement and prevents oscillation.
