Title: Apparatus responsive to the composition of a gaseous medium
IPC: G08B17/113
Filed: 1958-01-21
Abstract: 828,121. Discharge apparatus. DETECTION ELECTRONIQUE FRANCAISE D.E.F. Jan. 21, 1958 [Oct. 24, 1957], No. 2035/58. Class 39(1). [Also in Groups XXXVI and XL(b)] In gas testing apparatus a voltage is produced indicative of the variation in the composition of a gas flowing through a first ionisation chamber when compared with a reference gas in a second sealed ionisation chamber XXXVI) and (Groups XL(b). The first ionisation chamber 1, Fig. 1 comprises a cathode 8, a radioactive source 12, e.g. a radium salt emitting alpha particles, the intensity of which can be controlled by the screw 13 and which is heated by the filament 12 to prevent the formation of an emission interfering moisture film, an anode 9 and a screen grid 11 placed downstream of the anode and negatively polarised with respect to it to repel back to the anode any negative ions carried past it by the gas flow, hence rendering the device largely insensitive to the rate of gas flow. In a modification, Fig. 2, the first ionisation chamber is arranged symmetrically and includes a pair of radioactive sources 24 and 24b on one side and another pair of sources 25a and 25b on the other side of the anode 10. This arrangement renders the operation of the device insensitive to the rate of gas flow in either direction.

IPC: G01M17/02
Filed: 1969-01-14
Abstract: 1,261,542. Testing pneumatic tyres. UNIROYAL Inc. 14 Jan., 1969 [2 May, 1968], No. 2047/69. Heading B7C. [Also in Division  G2] A method of testing pneumatic tyres for sub-surface structural irregularities comprises inflating a tyre T to a pressure at which it will have a tendency to grow over a finite period of time, and comparing a first growth stage of the tyre with a later growth stage by holographic interferometry to create an interference pattern 22, 22a representative of the growth of the tyre, any abnormalities in the interference pattern being representative of an' other than normal degree of growth at a respective section of the tyre and indicating the presence and nature of a corresponding subsurface structural irregularity therein. In one embodiment a hologram is made of one section of the tyre, e.g. a side-wall, the recording medium developed and the hologram reconstructed after a finite time interval when the tyre has grown, the reconstructed image being superimposed on the illuminated tyre at its axial growth stage. Any irregularities are shown as abnormalities 22a in the interference pattern 22. Alternatively, two superimposed holograms can be made at different growth stages and then reconstructed to give superimposed images and the same effect.  Reference has been directed by the Comptroller to Specification 1,142,702.
Patent GB-1599592-A (GB)
Title: Open top container and closure lid
IPC: B65D41/06
Filed: 1978-01-18
Abstract: A container (1) with a closure lid (7) is proposed, it being possible to reclose the container without it having to have a particular stiffness for this purpose, so that it can have a thin wall produced by heat deformation. The container has an outwardly directed circumferential flange which has gaps through which wings (4) are formed. Integrally formed on the container lid are bar parts (10) which extend inwards from a circumferential edge and have inclined sections, which results in the wings being gripped between the inclined sections of the bar and the underside of the lid when the lid is rotated. In this way, it is sufficient for only the lid to be stiff while the container and in particular its wings can be composed of a relatively thin, flexible material. <IMAGE>

Title: Closed-type electromagnetic compressor
IPC: F04B35/04
Filed: 1976-01-20
Abstract: 1513478 Lubricating MAN DESIGN CO LTD 20 Jan 1976 [4 April 1975] 2130/76 Heading F2A [Also in Division F1] Lubricating oil in the bottom of the closed casing 12 of an electromagnetically operated compressor is raised to a reservoir 122 by the flow of suction gas entering the casing through a tube 112. The tube 112 connects with a vertically extending tube 118 having a lower opening 116 below the oil surface 114 and an upper opening 120 positioned above the reservoir 122. Because the pressure at the opening 116 is higher than at the opening 120 oil flows upwardly with the suction gas and drips into the reservoir 122. The reservoir 122 is formed above a closure 62 of a delivery chamber 58 in a main body 36, the latter also defining a bore 34 for a reciprocable pumping piston 72. Oil collecting in the reservoir 122 is warmed by compressed gas in the chamber 58 to expel dissolved gas and flows along channels 124, 125 in the main body 36 to the grooved outer surface of the piston 72. Reciprocation of the piston 72 is produced by an armature 86 co-axially fixed thereto and caused to perform a suction stroke by the AC energisation, via a half-wave rectifier (94), of coils 90. The pumping stroke is performed by a spring 102.

IPC: B64C27/16
Filed: 1926-01-27
Abstract: 250,534. Isacco, V., (Assignee of Andres, V.). April 7, 1925, [Convention date]. Screw propellers.-The lifting propeller of a helicopter consists of a number of blades of aerofoil form mounted at their roots to swivel in sockets which form part of a hub freely rotatable on a vertical axle fixed to the upper portion of the fuselage, the propeller as a whole being rotated by engines driving screw propellers or by direct fluid-pressure engines mounted on one or more pairs of opposite blades. The swivel connection at the root of the blades is such that their pitch and also their inclination to the horizontal are variable, means being provided for maintaining automatically a certain relation between the two. The mean pitch of the blades may be manually adjusted by the pilot. On the upper part of the fuselage 1 is mounted by means of brackets 26, Fig. 4, a tubular axle 17 carrying at its top two ballbearings 28 positioned by nuts 29, 29<1> and a spacing sleeve 62. The outer ball races 63, 64 hold in place the hub 27, which is provided with four radial sockets 31 in which are received in ball-bearings 32 the roots of the longitudinal spars 70 of four blades 22. The outer races 68 of the bearings 32 are of concave spherical form so as to permit the spare 70 to have a rotary motion, and also a swinging motion in a vertical plane. The leading edge of each blade 22 is formed with a short slot 71, Fig. 2, in which is slidable one end of an arm 21 pivoted at its other end to the outer race of a ball-bearing 16, which may be moved up or down the axle 17, to vary the mean pitch of the blades, by a rod 13 connected to an arm 11 rigid with a lever 10 associated with a toothed locking sector 25. The slideway 71, movement of the arm 21 in which may be damped by a spring, permits a slight variation of the inclination of the blade without involving a corresponding variation in the angle of incidence. Two of the blades 22 have mounted thereon engines 34, Figs. 2 and 5, driving screws 38, 43 in opposite directions, and controlled by cables 53, Fig. 4. fixed to the outer race of a ball-bearing 52 slidable on the axle 17 through a rod 50 and pedal 51. The outer screw 38, Fig. 3, of each pair is keyed to the engine shaft 37 and carries a gear wheel 39, meshing with one or more pinions 40 mounted on bearings 41 integral with a socket 42 fixed to the blade 22. The inner screw 43 is mounted on a ball-bearing 46 on the socket 42, and carries a gear wheel 44 meshing with the pinions 40. Due to the swivel mounting of the blades 22 in the sockets 31, during rotation they automatically assume an inclination to the horizontal such that the perpendicular and horizontal components of the centrifugal force balance the efforts of thrust and drag, thereby minimizing the stresses to which they are subjected. When however the thrust on a blade tends to increase its inclination the pitch or incidence is correspondingly diminished through the medium of the sliding arm 21.

Title: Sterilising liquids
Inventor: CLARK REGINALD THOMAS
IPC: A23L3/22
Filed: 1964-01-20
Abstract: A continuous process for sterilizing liquids, especially milk, comprises preheating the liquid by indirect heating, rapidly heating the liquid under pressure by indirect heating to the sterilization temperature, passing the liquid after at least partial pre-heating or after sterilization to a vessel maintained at subatmospheric pressure so that the liquid boils, thereby cooling and at least partially degassing the liquid, condensing the vapour evolved, and returning the condensate to the liquid, preferably to a point prior to sterilization.  After preheating, but prior to heating to sterilization temperature, the liquid may be maintained in a holding vessel to allow stabilization of solids dissolved, suspended, or dispersed therein.  A low pressure degassing vessel, similar to that employed after sterilizing, may be introduced between the preheating and sterilizing steps.
