Title: Apparatus for the production of a woven zip-fastener tape
Inventor: SHIMONO MUCHIJI
IPC: D03D35/00
Filed: 1981-03-23
Abstract: An apparatus for the production of a woven zip-fastener tape consists of a shedding device for a plurality of warp threads, of a winding mechanism for winding a wire, consisting of synthetic resin, in a conical path of rotation around a winding mandrel in order to form a series of wound coupling members, and of a weft-thread insertion device which is movable to and fro transversely to the warp thread shed and to the conical path of rotation, in order to insert into the warp thread shed a weft thread, by means of which the wound coupling members can be woven into a carrier tape along one longitudinal edge of the latter when the carrier tape is woven from the warp and weft threads. The weft-thread insertion device has an arm which, during the insertion of the weft thread, can be brought into engagement with the wire, in order to displace the latter out of the insertion path of the weft thread, so that the weft thread can be inserted gently, without coming into frictional contact with the wire.

Title: Yarn monitor in textile machines
Inventor: FORTUNA WALTER
IPC: B65H63/028
Filed: 1982-05-27
Abstract: For the aerostatic pivot bearing of a yarn monitor in textile machines, it is proposed to produce the bearing housing (2) from a material of low coefficient of friction and of high dimensional stability or to line it with this. For this, there is formed in the bearing housing (2) an annular gap (17) located opposite the feed bore (13) which is intended for the pressure fluid supplied from the bearing journal (1) and which is covered by a resiliently pressed-down piston (19), as long as the yarn monitor does not need to perform a control function. In a preferred embodiment, the lining of the bearing housing (2) is obtained by means of axially pressed-in bushes having a spacing between the mutually confronting end faces and forming the annular gap (17), into which the piston (19) projects. The chosen construction affords an increased switching accuracy and an easier and cheaper maintenance of the yarn monitor when wear occurs on the bearing surfaces of the pivot bearing. <IMAGE>

Title: Blocking device for a lock
Inventor: LASKOWSKI SIGISMUND
IPC: E05B17/14
Filed: 1983-06-13
Abstract: The invention relates to a blocking device for a lock with a key channel (15) and with retaining elements (86) for a body (20), especially a cylinder, actuable by means of a key (2), the retaining elements (86) freeing the body (20) for actuation, after the associated key (2) has been pushed into the key channel. In locks which have become known hitherto, the retaining elements could be actuated not only by the associated key, but also by inadmissible aids, so that the security requirements could not be met in a satisfactory way. These difficulties are to be solved by means of the blocking device according to the invention, a small constructional volume and a low outlay in terms of production being required. To achieve this object, it is proposed that the key channel (15) be assigned a blocking body (24, 80), by means of which the key channel (15) is shut off when the key (2) is pushed in. Furthermore, the key (2) has a recess (102), into which said blocking body (24, 80) can engage when the key (2) is pushed in. <IMAGE>
