Title: Catamenial appliances
Inventor: OTTO FREDERICK LEWIS
IPC: A61F13/64
Filed: 1960-03-23

Title: Improvements in hydraulic presses
IPC: B30B15/22
Filed: 1943-06-25
Abstract: 565,259. Hydraulic presses. MUIR, W. P. June 25, 1943, No. 10316. [Class 69 (ii)] When the working pressure in the cylinder 7 of a hydraulic press reaches a predetermined maximum value, all excess pressure fluid is by-passed through a valve 40, which opens at the above value, and passes along a line 44 to another valve 45 opening at a lower pressure whence it passes through lines 48 and 25 to the sump 26. The pressure in line 44 is thus main tained at the above lower value and may be utilized to operate the main valve 12 controlling the working and return movements of the press. In the form shown it does this by tripping a toggle 38 and so allowing the valve piston 15 to move to the right under the action of a spring 35 and an adjustable choke 62 gives a time delay before tripping so permitting the press to dwell on the work for a desired period. The pressure in line 44 may also operate through a line 70 to adjust the stroke of the pump 10 thus reducing the volume of pump discharge. In a modification, Fig. 2 (not shown) the valve 12 is operated by a pneumatic relay controlled by the pressure in line 44 and also by hand-operated push valves.

Abstract: 417,333. Oil-break switches ; arcrupturing. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) April 6, 1933, No. 10327. Convention date, April 6, 1932. [Class 38 (v).] In a liquid-break switch, the liquid is caused to flow across the arcing surfaces of the contacts as they separate by means of a piston h acted upon by a spring g in which energy is stored during the closing of the switch by the movement of a cross-bar c carrying the movable contact d, either the fixed or movable contacts having a lost-motion mounting whereby the contacts are maintained in engagement during the initial movement of the cross-bar towards the open position, the arrangement being such that after the lost motion has been taken up and the contacts separate, the piston moves independently of the cross-bar under the action of the spring g. In the arrangement shown in Fig. 1, the fixed contact b is hollow, and the lost motion is provided by slidably mounting the movable contact d on the cross-bar under the control of a spring n. The contacts are mounted in an extinguishing chamber a, and the piston h is rigidly connected to a surrounding insulating cylinder k, the bottom m of which is engaged by the cross-bar during the last part of the closing movement. In a modification, Fig. 2, the fixed contact b is in the form of a closed contact having a lost-motion connection with its support under the control of a spring n, and the movable contact d is hollow. Specification 386,322 is referred to.

Abstract: 816,062. Measuring thickness using beta rays. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 9, 1956 [April 12, 1955], No. 10793/56. Class 40 (3) In a method of measuring the thickness of a deposit, the intensity of the radiations in a narrow frequency band including a characteris. tic X-ray resulting from the projection of beta rays on to it is measured. In the embodiment described, see Fig. 1, plate 1 and deposit 2 are mounted in holder 3. Beta rays 7, emanating from a radioactive isotope enclosed in cylinder 5 of material capable of resisting the rays and in protective container 6, irradiate the deposit which emits X-rays 8 detected and amplified by photomultiplier tube 9 which may include a crystal 10 of sodium iodide activated by thallium. Screen 11 prevents retrodiffusion of the deposit and surrounding objects by stopping parasitic beta rays. After amplification in 13 the desired frequencies (energies) are filtered and fed to counter 15 to determine the thickness of the deposit. The spectrum of detected X-rays is plotted by measuring the activity corresponding to each frequency to which filter 14 is tuned; one narrow region of intense activity is then selected by the filter and measured, see Fig. 2, not shown. In cases where the nature of the deposit is known, immediate measurement of thickness can be made. Detailed results of an experimental determination (see Fig. 3, not shown) are given.

The hopper includes a worm-screw 25 driven by a coin-freed motor 12 to feed potatoes downwardly to a pivoted tray 31. The tray is counter-balanced by an adjustable weight 36 to normally block the hopper exit. On receiving potatoes, the tray pivots about 37 to tip the potatoes into the sieve. A tube 32 containing a freely movable ball 33 is carried by the tray to assist movement past the dead-centre. After a suitable time delay, a motor 9 operates to pivot the sieve about shaft 39. The motor also rotates worm screws 67 through chain-and-pinion drives to separate a cup from a stack. The separated cup receives the fried potatoes. The discharge shoot 68 is heated.
