Abstract: The device for the storing of filamentary material contains a thread storage and a feed nozzle associated with it, the thread storage having a thread carrier which rotates past the feed nozzle and the feed nozzle being arranged fixed in position and rigid; and the depositing of the thread (S.sub.1, S.sub.2, S.sub.3) on the thread carrier takes place in the form of thread packages (P.sub.1, P.sub.2, P.sub.3) which consist of partially superimposed turns so that the length of the thread package (P.sub.1, P.sub.2, P.sub.3) and thus of the entire storage can be kept small, so that the storage is particularly suitable for looms, especially when using so-called mixers. The thread carrier is preferably covered by a small plate at the point of the formation of the thread packages, and the thread packages are deposited in the space between the thread carrier and the plate.

Abstract: A filling-thread monitoring device for jet looms in which a filling thread is guided during its introduction into the shed of a loom in a first guide channel which is formed by spaced members and is partially open on its side, contains a first filling thread stop motion means for the giving off of a signal when the filling thread introduced does not reach its normal length and a second filling thread stop motion means spaced from the first stop motion means in order to give off a signal when the filling thread introduced exceeds its normal length by a predetermined amount. Between the two filling thread stop motion means, a guide member is arranged which extends over the space which is free of warp threads and has a second guide channel which lies in the extension of the first guide channel and is closed in the filling direction.

Abstract: There is disclosed a thread-feed device having a stationary winder drum storing a supply of thread which can be wound-on by means of a rotatable winder arm and removed overhead from the winder drum, and having a first monitoring device which automatically controls the rotary movement of the winder arm as a function of the length of the supply of thread formed. Within the region of the withdrawal end of the winder drum there is arranged a second monitoring device which gives off a first signal to a control unit upon each pass of the thread through its monitoring region during the withdrawal of the thread. The control unit counts the first signals and, as soon as their number reaches a predetermined adjustable value which corresponds to the desired required length of thread, there is given off a second signal by which a thread gripper is actuated so that the thread-feed device delivers precisely measured lengths of thread, such as required for instance for the filling insertion on jet looms.

Abstract: A reed for a jet loom, in which the filling yarns are introduced into the shed by a gaseous fluid expelled from nozzles arranged spaced apart over the loom width and which periodically enter the shed, which reed has first reed blades having a profiling on their one edge and together form a guide channel for the filling yarn; and in the region of the projection of the nozzles onto the reed there are provided second reed blades the shape of which at their one edge is so selected that the guide channel is open on the wall thereof adjacent the nozzles.

Abstract: A portable self-contained device for heating and spraying a coating material from a tank onto a surface, the device having a fluid fuel supply for heating the material, which fuel in addition to heating drives an engine that is coupled to a generator device for supplying electrical energy to heating elements in a spray hose and nozzle that communicate with the tank and to a main pump which causes a fluid medium to circulate to drive a stirring engine which operates a stirring apparatus in the tank, and to drive a discharge pump for discharging heated material through the spray hose and nozzle operatively connected to it.

Abstract: The production of pile fabrics in which the stroke of the batten of a loom during operation is periodically decreased from the value corresponding to a full stroke of the batten by a value for partial strokes which is referred to as the pre-beating distance.

Abstract: A building structure having outer walls and corner elements that simulate a log-type building, the corner elements having a plurality of alternate wedge-shaped blocks that project at an angle with respect to each other, and a plurality of log facing elements spaced from each other by a mortar joint spacer element, the mortar joint spacer elements abutting centrally the wedge-shaped blocks that project normal to the plane of said mortar joint spacers.

Abstract: A device for maintaining an insertion band against an oscillating insertion band wheel by providing a flexible element which is movable in oscillating fashion in synchronism with the insertion band and rests from the outside against the insertion band under an initial stress.

Abstract: An electrical fencing point device having a weighted spring-biased tip depressible in a body section of the point to complete an electrical circuit to a scoring apparatus for registering a hit, the body section being quickly separable to give access to the weight spring. The depressible tip has an adjustable contact means that is adjustable from outside the tip for varying the sensitivity of making contact with an electrical contactor for completing a circuit to the scoring apparatus for registering a hit.

Abstract: A separating device for manually making separations in solid materials in which a separating blade has a row of teeth that performs oscillating movements with a component directed parallel and a component vertical to the row of teeth in which the amplitude is not greater than twice the distance of neighboring teeth.
