Abstract: The invention relates to a bearing surface for the end portions of work elements, which extend across a roller of a textile machine, for example a carding element, a knife, a cover element or a grid rod.

Abstract: A drive belt assembly for a revolving flat card includes a flexible belt. At least a pair of connecting elements are integrally formed with the belt. The connecting elements include a cross-beam with an inclined surface. A locking element is disposed between the pair of connecting elements in order to prevent the connecting elements from approaching one another. The locking element is removable from the pair of connecting elements to allow for the approaching of the connecting elements to one another.

Abstract: EP-A-627505 describes a connecting system between a revolving flat bar of a revolving flat card and a flexible drive belt. The system is based on snap-in connections. According to EP-A-753610, every snap-in connection comprises two rails (230) which each touch an inclined surface (214, 216) on the belt. According to the present invention such a snap-in connection can be supplemented by a locking element (300) which prevents an inadvertent loosening of the snap-in connection.

Abstract: In some embodiments, the drive belt for receiving the flats in a revolving flat card employs pairs of connecting elements for snap-fitting into an aperture in an end head at one end of a flat. Each connecting element has an inclined surface which extends from the body of the belt to form an acute angle of from 60.degree. to 80.degree.. The end head of each flat has a rectangular opening to receive the pair of connecting elements and has transverse molding each provided with an inclined surface to mate with the inclined surfaces of the connecting elements of the belt. In another embodiment, the drive belt employs pairs of ribs of simple rectangular section to engage within a buckle element of a flat while each rib is able to flex about a root of the rib at the belt body.

Abstract: Improved connection between a revolving flat card and a drive belt. A connection between a flat rod of a revolving flat card and a flexible drive belt for the flat rods, having a flexible connecting element formed integrally with the drive belt and the connecting element being received directly in a part of the flat rod, for forming a snap-on connection, with the drive belt being arranged on a side opposite of the flat rod and including a flexible projection, with the projection being adapted for a frictional engagement, in a clampable manner, with a respective receiving element located at the ends of the flat rod.

Abstract: In order to improve the incendiary effect of munitions the hollow compartment of a projectile body of a shattering and incendiary shell or grenade is provided with an incendiary charge and two explosive charges. The incendiary charge possesses at its rear region or end a substantially funnel-shaped recess or cavity into which there protrudes a substantially conically-shaped tip of the first explosive charge of said two explosive charges.

Abstract: A spinning projectile fuze contains a rotor which is retained by a safety spring in the form of a substantially ring-shaped disk in a safety or unarmed position. To enable the ring-shaped disk to release the rotor it must be pressed flat both by the firing acceleration and also by the spin. This ring-shaped disk possesses cut-outs or recesses by means of which it is subdivided into segments which are bent in an undulated or wave-shaped configuration.

Abstract: A base fuze for a spinning projectile comprising a firing pin for piercing a detonator cap, a hammer sleeve secured to the firing pin, a self-destruction spring by means of which the hammer sleeve together with the firing pin can be displaced towards the detonator cap. An inertia body is provided for increasing the response sensitivity and is located behind the hammer sleeve. Upon impact of the projectile the inertia body bears directly at the hammer sleeve in order to increase the mass of the hammer sleeve when piercing the detonator cap by means of the firing pin due to the inertia of such inertia body.
