Title: Improvements in and relating to a clutch thrust bearing and device equipped with thelatter
IPC: F16C33/76
Filed: 1958-07-08
Abstract: 843,528. Roller bearings. PITNER, A., and ROULEMENTS A ARGUILLES S.A. July 8, 1958 [July 8, 1957; June 16, 1958], No. 21783/58. Class 12 (1). A self-centring thrust bearing, for transmitting an axial thrust to the thrust plate E of a conventional clutch device C, comprises two annular plates 1, 2 forming opposed annular races 3, 4 for rollers 5 accommodated in apertures 7 in a thin annular cage 6, the periphery of the plate 1 carrying an L-section cap 8 which extends axially and radially of the plate 2 with clearances which permit a degree of relative radial movement between the plates 1, 2 while preventing substantial variation in the axial thickness of the bearing. The cage 6 is preferably pressed out to restrict movement of the rollers in at least one axial direction, and the annular cavity formed by the cap 8 contains a lubricant, e.g. a mixed soap of calcium and sodium. During a clutch disengagement thrust, exerted by a fork F pivoting in the direction of an arrow f, the plates 1, 2 assume a coaxial relationship and there is a radial clearance r between the inner face 12 of the cap 8 and the outer face 13 of the plate 2, the friction between these two faces, which contact for short periods at the start and finish of a clutch disengagement, being made as low as possible by undergoing a treatment, e.g. of phosphating, nitriding, or cementing. The plate 2 is fast with a bearing surface 14 adjacent a shoulder 15 on an annular thrust ring G which is coaxial with a driven shaft B and co-operates with the fork F. Sealing rings H<SP>1</SP> and I<SP>1</SP> on either side of the bearing engage respectively in recesses 21, 22, in the thrust ring G. In a modification, Fig. 5, the centring of the bearing during a clutch disengagement is ensured by providing a co-operating conical face 28 on the thrust plate E. The cage 6a has a radial clearance relative to the cap 8a which is of channel section and is formed of two L-section parts. The sealing rings differ from these shown in Fig. 2. Various other minor modifications are described which include the provision of conical or fusiform rollers and different forms of cap members 8.

Abstract: 973,281. Thin-walled containers. PLASTIC PACKAGING Ltd. June 8, 1962 [June 16, 1961], No. 21868/61. Heading B8D. A thin-walled container sealing member has a localized pressure part joined to a supported part at an abrupt shoulder defining a local weakness to be torn when pressure is applied. A lid 13 for a container comprises a polystyrene disc sealed to the rim of the container by an annular flange 14 adjacent which is an annular depression 15 bridged by four equi-angularly spaced ridges 16. Pressure on one of the ridges sets up a tension at the junction between the ridge and shoulder 19 formed by the outer wall of the depression and the flange 14 causing a split in the lid which can be easily enlarged and the container opened. For a tubular container the members 16 may be formed in an end wall integral with the container wall. Specifications 904,078 and 904,767 are referred to.

Title: Improvements in or relating to measuring devices for ascertaining he surface weight of moving webs
IPC: G01N23/16

Abstract: 902,144. Measuring devices using radioactive radiation. LIPPKE, P. June 23, 1960 [Nov. 18, 1959], No. 21977/60. Class 40 (3). A measuring device for ascertaining the " surface weight " of a moving web by reflection of radio-active radiation from its surface comprises indicator means responsive to the reflected radiation and a source of the radiation mounted in a feeler head in conjunction with means for maintaining the radiation-reflecting surface of the web in an invariable planar position in relation to the radiation source and the indicator means. The head comprises a cylindrical housing 1 enclosing a source 4 of radio-active radiation and concentrically arranged indicators 6 disposed within a lead shield 5. An outer casing 2 forms an annular chamber through which cooling air is passed from a source 3. The lower open end of the housing 1 is closed by a thin diaphragm 7 against which the web 9 to be examined is urged with slight pressure to provide an invariably positioned surface from which the reflection takes place. The diaphragm 7 may be a thin sheet of mica or of a suitable plastic. The head 1 may be combined with a detector 18 for ascertaining the actual moisture content of the surface of the web, and the two devices may be conjointly mounted in a support 8 carried by a frame which can be traversed or oscillated across the width of the web. If the web should break or its supply be exhausted, the counter or integrator associated with the indicators 6 provides a substantially greater signal which can be utilized to operate pneumatic or electrical means to position a cover over the diaphragm 7 and/or the indicators 6, and also to move the combined heads 1, 18 to a lateral position clear of the web 9.

[Class 102 (i).] In a fuel-ignition pump of the type in which the injection is effected by means of an accumulator plunger 13 loaded by an adjustable spring 14, the pump plunger 8 is connected to a piston 7, which is operated against the action of a spring 11 by the pressure in the engine cylinder 6, admitted to the piston 7 by a pipe 5. Injection takes place through a passage 18 and a groove 16 in the plunger 8 and a passage 10 and nozzle 3. The plunger is rotatable by means of a rack 20 and pinion 19, and is formed with an inclined edge 12, which controls the suction passage 9. Alternatively the amount of the charge may be controlled by a valve independent of the pump plunger, or by limiting the stroke of the pump plunger by means of an adjustable stop. The accumulator plunger may be loaded by the pressure in the engine cylinder. Specification 375,151 is referred to.

A process for adding a material to molten metal comprises feeding the material to the metal in a confined space over all or part of the surface of the metal. As shown, applied to the addition of magnesium to cast iron, to produce spheroidal graphite, a chamber 1 of refractory material, open at one end and having a curved tube 3 fitted at the other end, is placed with its open end below the surface of the molten metal which may be covered with a layer of coke 8. The free end of the tube has a removable cap 4. A pellet of magnesium, e.g. made from magnesium swarf, is placed in the tube and cap screwed on. The magnesium is then allowed to slide into the chamber where it reacts with the cast iron. Air is excluded from the reaction in order to prevent explosion and to limit the violence of the reaction.
