Title: Warning device for cylinders for liquefied gas under pressure
Inventor: ADAGLIO MARIE-FRANCOISE
IPC: G05D9/02
Filed: 1967-11-09
Abstract: 1,202,918. Fluid pressure control valves &c. M. F. ADAGLIO. 9 Nov., 1967 [29 Dec., 1966; 17 May, 1967; 6 July, 1967], No. 51022/67. Heading F2V. [Also in Divisions F4 and G1] In a device for giving a warning when liquefied gas under pressure in a cylinder reaches a predetermined level, a chamber 6, supported within the cylinder 1, has a lever 16 which is pivotally on a ball-and-socket joint 17 and carries at one end a weight 21, which is normally completely immersed in the liquefied gas, and a counterweight 24 and the arrangement is such that gas in the liquid phase, when the cylinder 1 is full, exert an upward force on the weight 21 to pivot the lever 16 to open a valve 11 to allow gas in the upper part of the cylinder 1, to enter chamber 6, orifice 8 and discharge nozzle 5, but when the liquefied gas level drops the weight 21 falls to close valve 11 and gas within the cylinder 1 lifts open a flap valve 14 until a pressure equilibrium within the chamber 6 causes valve 14 to close until the pressure, due to the gas passing from the chamber 6 to the nozzle 5, in chamber 6 drops and the valve 14 is again opened, the resulting noise of the valve 14 returning to its seating giving an audible warning.

Title: Mechanical resonator frequency measuring apparatus
IPC: G04D7/12
Filed: 1975-12-15
Abstract: When mechanical resonators consisting of a magnetic material are calibrated by controlled removal of material by means of sand blasting, the resonators are excited into mechanical oscillations via the alternating field of a coil and the frequency of the oscillations is measured with the aid of a microphone. For this purpose, premagnetisation of the resonators is required. After the actual calibration process, the resonators are to be sorted with respect to the resonant frequency achieved and the oscillating capability. To carry out these different types of work cycles fully automatically in one device with relatively little technical complexity, the resonators are supplied by a vibrator device (4a) to a guide rail (5a), demagnetised in the latter, then magnetised for the calibration by a magnetising device (10a) and supplied to the holders (3a) of a rotary indexing table (2a). The rotary indexing table is used for supplying the resonators to a sand blasting calibration device (11a) and to various ejection points (12a, 15a) in accordance with the resonant frequency achieved. <IMAGE>

To stabilize clutch control by compensating for a negative rate characteristic of the diaphragm spring 16 of a diaphragm spring friction clutch during the final part of the declutching stroke of its thrust-bearing 21, the piston 26 of an hydraulic slave cylinder 27 effecting clutch disengagement, through a rod 28, a lever 22 and said thrust bearing, is arranged to act also on a compensating return spring which reacts on a fixed abutment and is such that the declutching force at 26 continuously increases throughout thrust bearing declutching stroke. As shown, the spring comprises a straight coil spring 29 surrounding the rod 28 and bearing on a screwed-in cylinder end plug 30. The spring is ineffective during a first part of the declutching stroke, due to a clearance J between the spring and the piston in the clutch-engaged condition, but is progressively compressed during a second part of the declutching stroke. An additional return spring, of small force, provides return action throughout the entire stroke. In Fig. 2 (not shown), the spring 29 is replaced by a conical coil spring which is effective throughout the entire declutching stroke.

Abstract: 1,203,355. Underwater risers. NORTH AMERICAN ROCKWELL CORP. 11 Nov., 1968 [1 April, 1968], No. 53381/68. Heading F2P.  An underwater riser comprises a plurality of flexible plastic or metal pipes 14 or/and electric conduits 12 providing data transmission lines, the assembly being made resistant to a relatively high degree of tension, whilst at the same time maintaining flexibility, by the inclusion of a core member 10 of high tensile strength, such as a braided steel cable, and by encasing the assembly in a tough but flexible sheath 18 which is filled with an elastomeric filler 16. The filler 16 may be partially foamed to introduce buoyancy where the riser extends to a considerable depth, the amount of foaming preferably being varied throughout the length of the riser so as to be less at greater depths where greater resistance to water pressure is desired. Such a riser is placed under tension between a riser base on the water bed and either a surface vessel or a submerged buoy which applies the desired tension, thus reducing the flexing movement of the riser in stormy conditions. A marker buoy is attached to the submerged buoy.
