摘要:
Decorations resembling stained glass miniatures which release perfume into the atmosphere are manufactured from perfume-containing thermoplastic resin compositions and multiple-opening frames. The method of filling the resin composition into the openings of the frames provides a secure interlock between the filled resin and the ribs of the frames, and in a preferred procedure, the bottom surface of the filled resin is clarified to improve the transparency of the filled resin, which is preferably employed in multiple colors.

Metal containers, such as cans, are printed when empty by means of dye diffusion transfer, the dyes being first printed on to a paper web which is cut into individual carriers. Each carrier is secured, somewhat in the manner of a label, to a container by a water-soluble adhesive so that, upon being heated to effect dye transfer, the carrier comes into intimate contact with a suitably receptive coating, pre-applied to the container, solely by virtue of its own shrinkage. The carrier and adhesive are subsequently removed by water spray.

In a shredding machine having contra-rotating cutter shafts (16, 17) carrying interleaved disc-like cutters (18, 30), each having at least one cutting tooth (36), each cutter comprises a plurality of body members (34, 35) so that any cutter can be removed individually without dismantling the cutter and shaft assembly. To reduce danger of damage under exceptional impact forces at the cutting edge (37), a gap (47) is provided between the cutter body members, so that the part having the affected cutting edge can tilt slightly, with some elastic deformation, to absorb some of the impact energy; preferably the body members are mounted together through springs (40, 41) which also absorb some impact energy.
摘要:
A method of and apparatus for machining a workpiece (2), such as ceramic, with an energy beam (B), e.g. a beam of energetic ions or laser beam, produced by a beam generator (1). A carriage (3), having the workpiece securely mounted thereon, and the beam generator are relatively displaced to cause the beam to move in a scanning manner along a prescribed path on the workpiece surface. An acoustic emission from the workpiece being machined is sensed by a transducer (7) disposed in contact therewith to provide a control signal which is applied to the generator for controlling the energy or energy density of the beam and ! or to a drive unit for displacing the workpiece relative to the beam generator to control the rate of relative scanning displacement between the energy beam and the workpiece.

A flow meter is provided using a fluid responsive solid member (7) which is introduced into a flow chamber (6) defined in a vertically standing tubular housing (1) and which, with the flowing fluid (F) supplied through an.inlet (2, 3) at the lower end of the housing and discharged through an outlet (4, 5) at the upper end of the housing, is propelled to a level as a function of the volume rate of flow of the fluid (F) within the chamber (6). The solid member (7) is composed at least in part of an electromagnetically susceptible material and an electrically conductive winding (8) is disposed in an electromagnetically inductive relationship with that member (7) to present a reactance which varies as a function of the propelled position of the member (7) in the flow chamber (6).

The coupling comprises two coaxial discs (1, 11; 26, 28; 36,38; 46, 48) a resilient ring (8; 29; 39; 49) of frictional material positioned between the discs, means (14) for retaining the ring substantially coaxially with the discs, and means (7; 27; 37; 47) for biasing the discs into frictional contact with the ring. The clutch includes an additional means for engagement and disengagement of the discs. If the clutch is a slipping clutch it includes setting means (6) for the adjustment of the biasing force exerted by the biasing means (7). The brake has the same element as the clutch but one of the discs is stationary.
摘要:
A novel pencil core (20) constituted by a plurality of filaments (10) of a pencil core material (2) individually having a thickness of 10 to 250 microns, and bundled and joined together with a binder material (13). Such a pencil core (20) is manufactured by (a) producing a semi-soft core material (2) of graphite and a synthetic resin, (b) extruding said core material (2) through nozzles (4) to produce a plurality of filaments (10), bundling said filaments (10) together in a ring (7b) into which is forced a binder material (13) by a screw-feed device (7c-7m) to encase the filaments, and (d) compressing the bundled and encased filaments (10) between rolls (9a, 9b) to produce the finished pencil core (20). Heat-treatment is provided by various heaters 6a, 6b, 8).
摘要:
Dans un conteneur metallique ayant au moins une couture par laquelle deux bords metalliques chevauchants sont assembles, au moins l'un des bords (58) possede une couche polymere elastique (56) liee fermement au metal, de telle sorte que lorsque ce bord (58) est cousu sur un second bord (60), la couche polymere se deforme sans detruire la liaison, et se lie au second bord, creant ainsi un joint hermetique. Une couche de latex d'une epaisseur n'excedant pas 0,10 mm peut eventuellement etre incorporee. Des coutures auxquelles s'applique l'invention sont les coutures embouties, les doubles coutures interverrouillees ou les coutures longitudinales laterales. Dans le dernier cas, la couche polymere peut assurer la liaison pour fixer une couture a chevauchement simple.
