Title: Improvements in and relating to closures for containers
IPC: B65D45/18
Filed: 1939-04-27
Abstract: 528,101. Closures for containers. NOFER, P. April 27, 1939, No. 12646. [Class 125 (iii)] A container closure has a number of wire loops d depending from its rim c to engage projections b on the container. The projections have a sloping face f and the loops d have lower parts e bent upwards towards their centres so that when they are engaged beneath the projections b the closure is drawn resiliently downwards. The centre part g of each loop is curved outwardly to permit the insertion of a tool for opening or closing the container. The loops are sufficiently resilient to permit the closure to lift to relieve excess internal pressure when for instance, the contents are being boiled.

Abstract: 830,722. Nuts &c. MORSE, M. April 22, 1958 [April 26, 1957], No. 12662/58. Class 89(1) A nut assembly comprises a metal nut body 11, Fig. 4, and a sealing boot 12 of silicone rubber secured to the body by engagement with at least one annular groove 51, 74 in body 11, having a maximum width of from 0.015 to 0.040 inches and a depth of from 0.010 to 0.030 inches. The boot is applied by injection moulding and is subsequently cured for about one half minute at between 200‹ and 260‹F., thereby liberating benzoic-acid which, it is said, is trapped in the or each groove, due to the dimensions thereof, and causes partial de-polymerization of the silicone rubber, creating an adhesive which bonds the rubber and metal together in the groove. The boot may be formed with lips 80, 82 to form a lubricant reservoir 84 for a shaft 79 rotating in the assembly. In a modification, the nut member 106, Fig. 11, has annular grooves 138, 156, and the boot is formed as a cap 162, e.g. to cover the actuating lever of a toggle switch.

Abstract: 861,447. Laminated or moulded plastic sheet materials. POLIBENTO S.r.L. April 18, 1957 [April 24, 1956; Nov. 14, 1956; Dec. 18, 1956; April 4, 1957]; No. 12726/57. Class 140. [Also in Groups V and XVII] Thermoplastic materials, e.g. polyvinyl chloride or polythene are continuously formed by extrusion into parallel longitudinal tubes having their outer surfaces integrally connected, and are then heat-sealed along lateral lines to form cells into which is introduced compressed gas, liquids, pastes, powders or individual articles at the open end of the cells; which are sealed by heat and pressure effected by cooperating blades operating intermittently to divide the tubes into sequences of individuallysealed cells containing the material fed in. The plastic material is heated in a cylinder 2, Fig. 1, and is forced by a feeding screw through a slotted die 10, Fig. 4, having circular recesses at intervals, each with a central core 11 fixed by bridge arms 12. The cores are connected together by a feed-pipe 13 communicating with injection pipes 15, terminating in flexible airtight funnel nozzles 16. The extrusion sheet 4 consisting of a laterally connected tube assembly is filled with compressed gas, liquid, &c. through the injection tubes 15, and the filled tubes are then sealed between welding- blades 140 which apply heat and pressure to weld the filled tubes at predetermined intervals. The blades 140, Fig. 2, are reciprocated by levers 142 actuated by cams 143, and are provided at the pressure face with a silicone rubber pad in which is fixed an electricallyheated welding wire held by a sheet of P.T.F.E. During welding the tubular assembly is momentarily held stationary and the extrusion is allowed to deform in the region before the welding blades, and immediately after welding the assembly is drawn forward at slightly increased speed to correct the deformity. In a modification, a plurality of spaced welding- blades are provided, each with respective lever and cam units. The dies used to form the tubular sheet may be circular as shown or oval, triangular, or square section; and a bank of such dies may be used to form two or more interconnected layers of tubes. When solid articles are inserted, e.g. nuts and bolts, the feed-pipe 13 is dispensed with and the injection pipes 15 are extended upwards through the cores 11 to a suitable feed apparatus which supplies the articles at timed intervals to leave free welding spaces in the tube being filled. The filled assembly'may be severed into individual cells by cutting members to provide a series of the packed materials. Before severing the packed tubular assembly may be provided with a covering layer of textile or fibrous material. The products may be used as capsules for. packing materials as described, or as protective coverings, upholstery stuffing or buoyant garments, when filled with air or other gas, the pressure of which may be varied.

Title: Electrical apparatus for measuring damping ration
IPC: G01R27/28
Filed: 1970-03-18
Abstract: 1309161 Measuring mass flow-rate electrically HONEYWELL Inc 18 March 1970 [18 March 1969] 12928/70 Heading G1N A mass flowmeter comprises an oscillatory plate 46 forming part of a second order mechanical system i.e. a mechanical system of which the Laplace transformed transfer function is wherein w n  is the natural frequency of the system (150 Hz) and y is its damping ratio, mounted transversely of a conduit 48 on a rotor 104 and of which the damping ratio of the oscillations is proportional to mass flow-rate (see Specification 1283029) and which is connected with a gain control circuit which maintains the  oscillations of plate 46 at constant amplitude and produces a signal representative of the 10 KHz oscillations from oscillator 30 amplitude modulated in accordance with the angular position of the rotor whereby the signal across resistor 194 is proproportional to the amplitude of oscillations at the terminal 108 i.e. to the loop gain and is representative therefore of mass flow-rate. Correct phasing of the loop is assured by a phase-shifting circuit e.g. an integrator or differentiator. In a first embodiment the plate 46 is coupled to the rotor 104 of a microsyn 32 which amplitude modulates the signal from an oscillator 30 on winding 100 so that the output signal represents the instantaneous angular displacement of the plate. The output signal is fed from winding 102 to a peak amplitude detector and rectifier 16a from which a positive-going signal is compared with a negative reference source 20 representing a required peak oscillation amplitude. The comparator 18 output acts to control the conduction of transistor 190 and thereby the signal fed to winding 154 of torque 14 driving the oscillatory plate. A further winding 150 of the torque is driven by an integrator 12 which phase-shifts the signal from the microsyn 32 after demodulation at 34. The torque developed on the rotor 104 is proportional to the product of the signals on windings 150 and 154. In alternative forms of the first embodiment the phase-shifting loop is a differentiator or a loop having a Laplace transformed transfer function of one of the forms Tp+1, 1/Tp+1 where T is the loop time constant. In a second embodiment Fig. 4 (not shown), the rectifier circuit 16a is replaced by a sample and hold circuit (16b) for peak amplitude detection.

Abstract: 280,762. Billinghame, W. E. May 25, 1926. Emulsions, making. - Aqueous emulsions of vegetable and animal oils, fats, greases, waxes and the like are prepared in concentrated form by treating liquid resin or other resin with alkali to produce a neutral soap containing 39 per cent of resin, adding with agitation an equal portion of oil or the like, melted if necessary, and finally adding two parts of a soluble casein or like protein solution. This concentrated emulsion may be employed as an emulsifying agent for producing further quantities of emulsion by adding with agitation nine times the amount of water and subsequently an equal quantity of oil or the like after which the emulsion may be further diluted. The casein or like solution employed is preferably prepared by dispersing nine parts of the protein in eighty four parts of water and adding with stirring, but without heating, one part of caustic alkali in six parts of water. The Provisional Specification states that the oil may be added before the water during the preparation of the bulk of the emulsion and the finished emulsion may have china clay incorporated into it in the proportion 10-50 per cent of the weight of the oily ingredient. Reference has been directed by the Comptroller to Specifications 8141/00, [Class 81, Medicine &c.]; 11028/03, [Class 15, Bleaching &c.]; 13151/05, [Class 81, Medicine &c.]; and 252,449.
