Suction device usable on at least one level (1) of a building, of the type comprising a suction tube (6) held in the hand and connected by a flexible tube (7) to a suction duct (8) connected itself to a centralized suction collector (2), characterized in that at least the suction duct (8) can be wound up preferably automatically on a movable winding device mounted on a vehicle (5) and driven by...

This invention relates to a solenoid device for a flow rate control valve and a displacement sensor. In a conventional solenoid device, it is not possible to obtain the characteristics permitting ease-of-control of the voltage applied to an electromagnetic coil and the stroke of a plunger, or the stroke of the plunger and the oscillation frequency of the coil. Thus, it is difficult to carry out a ...

An electric punch includes a main body frame (1) having two punching holes (35,35) leading to a waste storage chamber (4) below. A pair of guide bores (34,34) support a pair of punching blocks (36,36) aligned with, and movable into, the respective punching holes (35,35). Two operation arms (40,40) are pivoted on respective holders. Each operation arm (40,40) is connected to one punching block (36)...

Zum Verbinden zweier Fadenenden textiler Stapelfasergarne ist heutzutage das Spleißen mit Druckluft in einer Fadenspleißvorrichtung üblich. Die Fadenenden werden dazu in einen Fadenspleißkanal eingelegt, der in einem Fadenspleißkopf eingearbeitet ist. Es hat sich gezeigt, daß die Oberfläche des Spleißkanals einen wesentlichen Einfluß auf das Spleißergebnis hat. Um bei Spleißkanälen (6) eine reprod...

A method for catheter tipping includes applying to a catheter blank a layer of a noncuring aminoalkyl terminated polysiloxane lubricant, mounting the lubricated blank on a mandrel and advancing the mandrel-catheter assembly into a heated die so that the die causes the heated tip of the blank to assume the shape of the die. The catheter may then be cut beyond the shaped tip and easily removed from ...

A method of treating a rubber expandable tire cure bladder by forming a base release coat thereon followed by application of a lubricant topcoat. The base release coat is derived by applying a composite of an hydroxyl terminated polyorganosiloxane and an aminoorganosilane to an expanded bladder and thereafter applying a lubricant topcoat derived from selected polyorganosiloxane components. The inv...

In einer Webmaschine mit mindestens zwei Schussfadenspeichern (10,11), die längs neben der Webmaschine angeordnet sind, und mit einem Spulenhalter (2) zur Aufnahme von Schussfadenspulen (220, 221) wird jeweils eine der auf einem Tisch (21) gelagerten Schussfadenspulen (220, 221) zur Abgabe von Schussfaden (31) an einen Schussfadenspeicher (10) in Arbeitsposition gebracht. Der Spulenhalter ist plat...

A device for monitoring the thread supply in a thread-feeding device for textile machines has two measuring circuits (55, 56), of which one processes signals characterising the rotational movement of a rotatable element, for example a thread-feed roller (4), coupled in a non-slip manner to the thread (16) and the other measures the set desired thread-tension value of a desired-value transmitter (2...

The utility model relates to a hot tube-type vacuum-tube solar heat collector, a glass tube is made into double layers, the gap between two layers is made into the vacuum, the heat absorbing end of the heat pipe is put in the glass tube and outside the vacuum layer. As the heat pipe is not in the vacuum layer, the sealed connection of the metal and the glass is avoided, and the process is largely ...

An overshoe is provided for an orthopaedic cast such as a plaster cast. The overshoe comprises a sole, an upper piece connected to the sole and a toe cap. The upper piece has first and second parts adapted to receive a plaster cast in the overshoe and has fastening means, such as a "Velcro" (Trade Mark) fastening, allowing those parts to be fastened together to hold the cast firmly within the over...

An edging strip applicator has a handle 2 which is rigidly connected to an electrically heated pressure pad 3 and an axle of a roller 6. In use, the pad 3 heats adhesive under an edging strip and the roller 6 presses the strip firm in position (e.g. on the edge of a board) as the applicator moves in a continuous path along and above the strip. The pad 22 may be connected at one end of the handle 2...
