Abstract: 662,955. Making compound &c. sheets for bearings &c. GLACIER METAL CO., Ltd., TAIT, W. H., and LOVE, P. P. March 29, 1950 [March 1, 1949], No. 5565/49. Classes 83 (ii) and 83 (iv). Forging-machines.-In a method of compacting sintered strip material, for bearings &c. and which may be bonded to a steel or other backing layer, the strip is squeezed between platens 1, 2, with either continuous or intermittent movement of the strip. The platen 1, having a straight portion 1d to 1c and a curved portion 1c to 1e is pivoted to the press frame 4 at 4b and is operated by a crank 5 through toggle links 3, the strip 7 being fed intermittently. In a modification, Fig. 2, the press mechanism is suspended from pivoted links 10 and moves with the continuously-fed strip 7 while pressure is applied, release of pressure then allowing the press to swing back to its initial position at which the platens reengage the strip and move forward again. The toggle links are operated through gear-wheels 5a, 5b. The frequency of oscillation of the press may be adjusted by variation of the length of the links 10, or the use of springs connected between the suspended structure and fixed anchorages. Alternatively the press may be positively reciprocated in synchronism with the strip by a cam mechanism, which may also serve to effect a step-by-step feed of the strip. In another modification, the platen 2 is supported on a tapered element which may be adjusted axially and also swivelled about its centre and provided with adjusting means to permit of the spacing between the platens being parallel or tapered. In a further modification the platen 2 is supported by hydraulic or other means adapted to yield when the squeezing pressure reaches a predetermined value.

Title: Improvements relating to nuclear magnetic resonance apparatus
Inventor: PARKER LESLIE KEARTON
IPC: G01R33/46
Filed: 1960-02-17
Abstract: 968,144. Gyromagnetic resonance apparatus; recording apparatus. PERKIN-ELMER Ltd. Dec. 14,1960 [Feb. 17, 1960], No. 5641/60. Headings G1J and G1N. The speed of the magnetic field (or frequency) sweep in a nuclear magnetic resonance spectrometer is maintained proportional to the speed of the recording chart by employing for the sweep voltage the integral of the voltage produced by a tachogenerator driven by the motor which drives the chart. The beginning of the sweep is synchronized with the passage of a particular dark spot on the chart past the marker 25, Fig. 1, and the photo-cell 30, by employing the resultant signal from the latter to open gate 13,whereafter the tachogenerator voltage is integrated and applied to trigger circuit 31, the setting of which determines the open period of gate 13 and hence the sweep amplitude; to an oscilloscope time-base via terminal 17; and to the magnetic sweep coils via terminal 19 and voltage divider 18, the setting of which determines the magnetic field (or frequency) scale of the recorded spectrum. Monostable circuit 35 delivers a signal, 3 seconds after the receipt of the trigger circuit signal, to circuit 40 to stop the motor at the end of the sweep. A trace on the oscilloscope only is obtained by connecting source 45 to the gate via switch 12, and closing switch 39,whereby the delayed signal from circuit 35 at the end of a sweep reopens the gate to start the next. In a second embodiment, Fig. 2 (not shown), the motor drives the chart and, through a clutch, the spring controlled arm of a rotary potentiometer,the output from which provides the sweep voltage. In a modification, the clutch and spring control are dispensed with. The apparatus may be applied to either resonance or induction spectrometers, and permits variable speed recording, and a direct calibration of the recording chart in terms of field (or frequency). Reversal of the motor during a sweep enables the spectrum to be retraced in the reverse direction.

Title: Air reserve arrangement for breathing apparatus
IPC: A62B9/02
Filed: 1958-02-21
Abstract: 828,510. Respiratory appliances. SPIROTECHNIQUE. Feb. 21, 1958 [Feb. 27, 1957], No. 5723/58. Class 81 (2). A reserve arrangement for underwater breathing apparatus has the reserve valve mechanism located within the inhalation chamber of the regulator, to avoid wastage if leaks occur. A gas cylinder is connected to a coupling member 30 and air, passing down the central duct 34, is led through an annular passage 41 to a spring-loaded ball valve 66 and thence to the seating member 42 of the inhalation valve 20. A diaphragm 15 controls the inhalation valve 20, in the usual manner, through levers 16 and an outlet 12a is connected to the face mask. The air supplied by the cylinder is continuously used until its pressure is insufficient to lift the ball 66 off its seating and the cessation of flow serves as a warning, to the user, of approaching exhaustion of the supply. When this occurs the ball is positively lifted off its seating, to resume the flow of air, by a plunger 70 actuated through a cam 82 by a handle 92. Since the whole of the valve mechanism is located within the inhalation chamber 10, any air which may leak from it passes into the normal breathing supply and there is no wastage.
