Abstract: 1,126,886. Rotary vacuum pumps. GENEVAC Ltd. Oct. 18, 1966 [Oct. 18, 1966], No. 46455/66. Heading F1F. An oil-sealed rotary vacuum pump comprising an oil reservoir 10, Figs. 1, 2 and a pump chamber 11 inter-connected by a duct 20, includes an oil filled chamber 13 housing spaced apart discs 15, 16 secured to an extension of the pump shaft 12 and a freely rotating intermediate disc 18 formed with a notch 28 engaging the lower end of a plunger 27. The upper end of the plunger 27 engages a spring- loaded floating bar 22 carrying a rubber valve disc 23 controlling the duct 20. When the pump is operative, the discs 15 and 16 are rotated and the resulting oil drag rotates the disc 18 in the direction of the arrow A thereby to raise the plunger 27 and lift the bar 22 against its springs to unseat the valve 23 to allow oil to feed to the pump chamber. When the pump stops, oil drag ceases and the valve 23 becomes seated to prevent oil being sucked into the system being evacuated.

Abstract: 1325740 Making gaskets; stamping; punching CEFILAC 9 Oct 1970 [10 Oct 1969] 48360/70 Headings B3A B3Q and B3W [Also in Division F2] Metal protective rings are inserted in the apertures of a cylinder head gasket by cutting the rings from a metal sheet and beading the rings in position in the apertures, the cutting and beading steps being carried out in the same apparatus. The metal sheet 22, which already has a hole formed in it for each aperture in the gasket and has a cylindrical flange 30 around each hole, is positioned on a lower plate 23. Above the sheet the gasket 9 is positioned on a plate 5 attached to a die support plate 4. A punch 21 on a punch plate 12, and a lower punch 26 are provided in alignment with each aperture. During operation, the punch plate 21 is lowered until it contacts the support plate 4, the plate 4 then moving downwardly until it clamps the sheet 22 between the plates 4 and 23, Fig. 4. Further downward movement first causes the punch 26 to remove a ring from the sheet (inset, Fig. 5), and then to move the aperture over the ring. The ring is finally beaded around the aperture by a resilient part 21a of the upper punch 21. When the pressure on the punch plate 12 is released, the parts assume their initial positions and a further gasket and sheet can be placed in position.

Filed: 1975-11-26
Abstract: 1502178 Detecting atmospheric turbulence E F FLINT 26 Nov 1975 [10 Feb 1975]  48522/75 Heading G1A In a system providing discrete measurements of temperature within a field of view ahead of an aircraft, processing apparatus comprises means for providing: consecutive first signals representing the mean temperature within the field; consecutive second signals representing the temperature  difference between two vertically-spaced regions; consecutive third signals by combination of first and second signals; fourth signals by storing and averaging third signals; and a warning upon a predetermined difference detected between third and fourth signals.  A radiometer 20, Fig. 1, carried in an aircraft 19 includes a black-body temperature reference and a rotary chopper and filter coupled to a processing lens for deriving compensated temperature data from infrared radiation detected at points 1 - 10 in a circle 23 subtending subtending 4 degrees at the aircraft. At first a wavelength of 13.8Á the radiometer has an effective range of about 16 miles; and at a second wavelength the range is about 8 miles. The difference between measurements made at these two wavelengths provides a signal relatively free from cloud ice effects. The circle is swept once a second. Temperature-representative signals SR, Fig. 2 are averaged, 37, to give mean first signal S S , and the difference Sv between temperatures at e.g. points 1 and 6 is calculated to give second signals at 39. Third signals Ssv representing S S  + Sv are successively stored for two minutes at 43 and then discarded, a fourth signal representing the running average SA appearing at a line 44. Consecutive third signals S SV  are compared with their own running average S A  at 45, the magnitude of the difference Sw being compared with thresholds S T1  and S T2  to give a steady light 50 or a more urgent flashing light. Warning is thus given on the occurrence of variations either in temperature along the flight path or in vertical temperature gradient across it. The temperature pattern is displayed by concentric circles of respectively blue and yellow lamps 61-80 energized by gated signals from a comparator 53 indicating a temperature above or below the two-minute average. A biasing signal SB deducts the difference signal Sv from S A , so that the comparator reference is effectively a long-term average of signals S S ; thus in smooth flying conditions the upper half of the display will normally be blue and the lower half yellow.
