Title: Improvements in and relating to buttonhole sewing machines
IPC: D05B73/12
Filed: 1931-11-27
Abstract: 380,303. Buttonhole sewing-machines. HUGHES, R. M., 72, Cannon Street, London.-(International Button Hole Sewing Machine Co. ; 502, Harrison Avenue, Boston, U.S.A.) Nov. 27, 1931, No. 32955. [Class 112.] The main cam which sets the stitch-forming mechanism of a turret machine in operation and operates the buttonhole cutter has means for causing it to effect the cutting either before or after the stitching operation. The work is held on the bed 1 by the usual clamps 9 supported by arms 10 pivoted to the bed at 11. The clamps are opened and closed by the usual known means. The buttonhole cutter 280 is carried by an arm 29 pivoted to the frame 2 at 30. The cutter is given its cutting movements by a projection 31 on the top of the main cam 22. This projection engages the tail 32 of the cutter arm which is normally held in its raised position by a spring 33. The main cam 22 is rotated from a shaft 34 having spiral gear teeth meshing with gear teeth on the cam. When the machine is first started by depressing the lever 36, the shaft 34 is automatically coupled to a driving pulley and the cam 22 derives its initial turning movement from this pulley. During this movement the parts are brought to stitching position with the clamps closed. When the stitching position is reached, the stitch-forming mechanism is set in motion and the pulley is automatically disengaged from the shaft 34, the cam 22 being then turned by means actuated by the driving shaft for the stitch-forming mechanism in known manner. During the stitching of the buttonhole, the frame 2 is moved to and fro by the groove 38 in the upper face of the cam 22. When the stitching is completed the stitch-forming mechanism is brought to rest and the driving pulley is again clutched to the shaft 34 so that the final movement of the cam 22 is derived from this pulley. If the buttonhole slit is to be cut before the sewing operation, the cam 22 is stopped with the cutting cam 31 in the position relative to the tail 32 of the cutting lever shown in Fig. 13, and by the dotted lines of Fig. 1, while if the slit is to be cut after sewing, the stopping position of the cam is as indicated in full lines in Fig. 1. In the former case, as the cam 22 starts to rotate, the cutting cam 31 will act against the tail 32 before the stitching mechanism is set into operation. In the latter case as the cam 22 rotates, the projection 31 moves away from the tail 32, leaving the cutter 280 idle till the cam has nearly completed a revolution, that is, after the buttonhole has been stitched.

Title: A device for orienting axes of bodies
IPC: G01B11/26
Filed: 1970-07-07
Abstract: 1292394 X-ray apparatus COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 7 July 1970 [7 July 1969] 33017/70 Heading H5R [Also in Divisions B8 and E2] The device of Fig. 1 permits a body 28-e.g. a crystal-to be positioned and oriented such that an arbitrary plane therein lies perpendicular to an axis 22, by the use of two full-circle adjustment means. As shown, the goniometer head 26 of an X-ray diffractometer includes an eccentric platform 36 mounted within a rim 34 of a block 32 such that the axis of rotation 38 of the platform on the block 32 makes an angle of 7 degrees with the diffractometer axis 22. The crystal 28 is initially adjusted axially by rotation of screwthreaded block 44 within threaded turret 42, and radially by two sets of grub screws 50 (one pair shown) until the desired crystal plane passes through the point of intersection of the axes 22 and 38; the normal to this plane, i.e. the crystal axis, will then, in general, possess an arbitrary direction with respect to axes 22 and 28, as shown by the line 54 in Fig. 4. The crystal is rotated from its above-described initial position by rotation of the turret 42 upon the platform 36 until the crystal axis 54 occupies the position 54a, Fig. 5, lying in the imaginary cone 52 generated by rotation of the axis 22 about the axis 38. Thereafter, the turret 42 is clamped relative to the platform 36 (see Div E2), and the platform is rotated on the block 32 to rotate the crystal axis around the cone 52 until it coincides with the axis 22. Since the exact rotation initially required to move axis 54 to the position 54a of Fig. 5 is not known, the desired final position of coincidence with axis 22 is obtained by a process of successive approximation involving repetition of the above sequence of adjustments. It is not necessary that the initial rotation of the crystal to bring the crystal axis on to the cone 52 should be about the desired axis 22, and an alternative embodiment is disclosed (Figs. 7 to 15, not shown) in which this rotation may be about a third axis.

IPC: C08L27/06
Filed: 1968-07-12
Abstract: 1,183,015. Laminates. W. R. GRACE & CO. 12 July, 1968, No. 33456/68. Heading B5N. [Also in Divisions B6 and C3] A laminate comprises a thermoplastic film, having a melting or softening point of at least 200‹ C., bonded to a fibrous base layer, impregnated with a thermosetting resin, by an adhesive composition of a phenol-formaldehyde resin and a polyvinyl chloride plastisol. The thermoplastic film may be of nylon. The base layer may be of paperboard, e.g. cotton linters impregnated with phenol-formaldehyde resin or wood flour and cellulosic fibres impregnated with a blend of formaldehyde phenolic resin and a butadiene/acrylonitrile copolymer. The base layer may be formed by suspending in water a mixture of paper pulp and particles of the resin and then forming the mixture into a sheet in a machine before drying the sheet. Alternatively, a sheet of paper pulp may be impregnated with phenolic resin and water, squeezed between rolls and dried in an oven. The P.V.C. in the adhesive composition may include a plasticizer, e.g. a phthalate, such as dioctyl or diisooctyl phthalate; a polyester; or a phosphate, such as cresyl diphenyl phosphate. A curing agent e.g. imidazoline for the P.V.C. may be included. Preferably a single material serves both as plasticizer and curing agent. Such a material is the reaction product of imidazolines with epoxy compounds. The adhesive composition may be applied as a coating to either the base layer or the thermoplastic film prior to laminating. Various coating techniques may be used; e.g. the adhesive may be applied to silicone release paper, to the adhesive side of which the thermoplastic film is then applied, pressure then being applied between rolls before stripping off the release paper. During the laminating process, the resins are not cured. The laminate may be used to form a printing matrix in which case a heated hydraulic press holds the laminate and a metal type form in contact for a time sufficient to cure the resin in the base layer and the adhesive composition. The face of the type form deforms the thermoplastic film and the adhesive layer throughout their respective thicknesses, the base layer being deformed at its inner surface only, Fig. 2 (not shown).

The remainder of the effluent hot gases are led from the hearth as hot exhaust gases to an exhaust stack 41 containing a recuperator 40 used to preheat incoming air which is thereafter fed to the burner through duct 44. As shown the flow of gases through the scrap melting system is augmented by an injector 53 utilizing a portion of the exhaust gases withdrawn from the stack 41 by a fan 54 and supplied via a line 55. Alternatively a fan may be used instead of an injector (see Fig. 4, not shown). A second preheating chamber (70, Fig. 4) may be provided for receiving compacted bales of aluminium scrap to be charged into the hearth. A thermocouple 56 in the afterburner is linked to a temperature controller 57 which is arranged to control the fuel and air feed to the burner nozzles 38, 39. The temperature of the molten bath 26 is sensed by a thermocouple 58 connected to a controller 59 arranged to control a valve 60 and hence adjust the rate of exhaust gas flow through the injector 53 which in turn controls the recirculation rate of effluent hot gases to the combustion chamber 36. The temperature of the scrap preheating drum 28 is sensed by a radiation temperature detector 62, and the flow of recycled effluent gas to the combustion chamber varied through a controller 61 and damper 63 in the return duct 46 in accordance with the sensed temperature. An arcuate radiating panel 48 extends from part of the furnace wall structure 49 into and through the preheating drum 28.
