Abstract: 708,448. Levelling heads for surveying &c. instruments. KERN & CO. AKT.-GES. Sept. 14, 1951 [Sept. 14, 1950], No. 21690/51. Class 97(2) [Also in Group XIV] A tripod for a measuring instrument comprises a ball joint formed of an upper part provided with a spherical zone and on which a supporting plate for the instrument is mounted and a lower part also provided with a spherical zone and which is engaged by a clamping plate, the parts holding between them an annular tripod plate on which tripod legs are pivoted, a central spindle formed integrally with the supporting plate and extending vertically downwards between the parts of the tripod so as to be free for limited angular movement, a clamping nut screw-threaded on the spindle to engage the clamping plate, and a removable lengthening rod secured to the lower part of the spindle. As shown, a hollow top part 3 and a lower part 4 of a ball joint rest on an annular plate 1 to which tripod legs 2 are pivoted, spherical zones 7, 8 on the parts 3, 4 being concentric but the radius R of the zone 8 being greater than the radius r of the zone 7. A supporting plate 10, resting on the zone 7, has a threaded stud 4, for connection to the instrument, and a vertically depending spindle 12 threaded at 15 for a nut 14 bearing on a clamping plate 13 resting on the zone 8. A cylindrical extension 5 of the part 4 is received in a guide 6 of the part 3. On the lower end of the spindle a removable, hollow lengthening rod 16 is adjustable axially. In use the tripod is erected over the reference point and the nut 14 loosened. The point 17 of the lengthening rod is set on the reference point and the spindle 12 is made vertical by moving parts 3, 4. A levelling indicator 19 is provided. Tightening of the nut 14 locks the supporting plate 10 and tripod plate 1 relatively to each other and when the instrument is screwed to the plate 10 only precision levelling is required. The lower part of the spindle 12 may be provided with a scale by which the level of the plate 10 above the reference point may be read from the upper edge of the rod 16. The rod 16 may be replaced by a holder for a plumb line. An optical plumb line may be used for centring the spindle 12 and setting it in a vertical position.

Abstract: 574,077. Protective cut-out arrangements; thermal switches. AKT.-GES. BROWN, BOVERI, & CIE. Dec. 31, 1943, No. 21916. Covention date, Dec. 31, 1942. [Class 38 (v)] A thermal overload relay employing a mass forming the thermal image of the apparatus to be protected, has a column of oppositelydirected bimetallic plates d in a thermallyinsulating sleeve f<2> around which is looped a striplike heating resistance b energized by a current transformer in the line. Resistance b is spaced by thermally-insulating sleeve f<1> from a metal housing g in which interchangeable heat-storage masses e<2> are supported by an intermediate member u, the whole being enclosed in an insulating hood h supported by poor-conductivity supports on a frame. The base of the column d rests on the support q of an axle i which is rotatable by the expansion of the column so as to throw a lever o overcentre and close trip contacts. The drive includes a differential gear, of which the wheel m has a pointer for setting the desired tripping temperature, whereas the wheel l carries a pointer indicating the temperature of the protected apparatus and may operate a maximum-temperature indicating pointer (not shown). An instantaneous (or retarded) maximum-current electromagnetic relay s making an alternative trip circuit also closes contacts for short-circuiting the heater b, the current in which may be adjusted by a variable shunt r. The elements b, f, g determine the shape of the initial part of the temperature-time curve, whereas the shape of the final part can be varied to suit the particular apparatus by inserting suitable masses e<2>.

Title: Improvements in or connected with means for feeding textile fabrics to or through machines
IPC: D06C3/00
Filed: 1933-08-05
Abstract: 423,600. Feeding webs. WHITELEY, E. G., Beech Works, Commercial Street, Morley, Yorkshire. Aug. 5, 1933, No. 22074. [Class 100 (i)] In feeding textile fabrics to or through machines, the fabric passes over a roller in the form of a cage-like structure, the surface of which is of a flexible nature and which is provided with means for varying its contour during running to enable the tension to be changed at different points in the width of the cloth. The roller comprises a plurality of metal, wood, or other flexible laths 1 somewhat spaced apart around a central spindle 2, and each lath is connected by four links 3 to four sliding collars 4. The collars 4 are connected to push or pull rods 5 and the links 3 are inclined as indicated, each centre collar 4 being attached to the same set or pair of push or pull rods 5 as that of an oppositely inclined end set of links. Each set of rods 5 is actuated by a separate sliding boss 6 carried by the spindle 2, each boss being rotatable but non-slidable in a nut 7, both nuts being mounted to engage oppositely inclined threads on a spindle 9 operable by a crank 11, the arrangement being such the bosses 6 are moved axially toward or away from one another according to the direction of rotation of the spindle 9. The movement so given to the rods 5 forces the end links 3 outwards and draws the centre links down, or vice versa, to produce a concave or a convex roller or any intermediate contour, as desired. The laths 1 are flexibly connected to fixed supporting collars 12 which afford fulcrums about which the laths can bend. The spindle 2 of the roller is preferably mounted in a pivoted bearing 13 at one end, the other end being carried by a bearing 14 adjustable by a crank 18, so that the axis of the roller can be tilted.

Title: Polypropylene compositions
IPC: C08L23/10
Filed: 1971-04-19
Abstract: 1348842 Polypropylene compositions DIAMOND SHAMROCK CORP 19 April 1971 [20 Feb 1970 22 Jan 1971] 22134/71 Heading C3P A polypropylene resin contains incorporated therein, per hundred parts by weight of the resin, (a) 0À1 to 10À0 parts by weight of a polyhydric phenol and (b) 0À25 to 20À0 parts by weight of a rosinous material and optionally (c) 0À01 to 5À0 parts by weight of a nucleating agent, e.g. sodium benzoate or a fine particle size polyvinylidene fluoride powder. The polypropylene resin may be a homopolymer or a copolymer of propylene with up to 25% by weight of a comonomer selected from α-olefins having 2 to 5 carbon atoms (other than propylene) and vinyl monomers. The rosinous additive is suitably selected from natural or synthetic rosins, or mixture thereof, e.g. wood rosin, wood rosin esters, modified wood rosin, a polymeric rosinous material, hydrogenated wood rosin, polyterpene resins, or synthetic ester resin. Particularly suitable for use as polyhydric phenols are resorcinol, substituted resorcinol, hydrocarbyl-substituted gamma-resorcylic acids and bis phenols of the formula wherein R is alkylene, a sulphur-containing radical, e.g. -S- or -SO 2 -, R<SP>1</SP> to R<SP>IV</SP> are H or alkyl radicals having less than 15 carbon atoms and n and m are integers, which may be 1, 2 or 3. Fillers and other conventional additives may also be present. The compositions can be extruded or moulded and are particularly useful in the preparation of shaped platable polypropylene articles. In preparing the latter the polypropylene composition in the form of a shaped article, e.g. in the form of a plaque, is treated to provide a non-electroplated, e.g. vacuum or chemically deposited, electricallyconductive coating intimately adhering to the surface and an electroplated metal coating deposited on the electrically-conductive coating. The first coating may suitably be chemically deposited nickel or copper and the electroplated coating is suitably copper.
