Abstract: The control serves for driving the needle bar and for the transport of the sewing material on embroidering, stitching or sewing machines, separate drive motors (MN, MX, NY) being provided for the respective units. To match the working speed of the machine as closely as possible to the particular pattern to be produced or to the materials to be worked, the individual drive motors are assigned pulse transmitters (GN, GX, GY). During the period of time (ta) between the exit of the needle and the re-entry of the sewing material, during which the sewing material has to be adjusted, the pulses coming from the pulse transmitter (GN) of the needle drive are summed in a computer (CR), as are also those coming from the pulse transmitters (GX, GY) of the drive motors for the sewing material. These pulse trains are compared with those which are fed to the computer (CR) via a reader (L) from the information carrier containing the sewing or embroidering program. The pulse trains and pulse counts thus received in the computer are compared here, and if there are deviations and differences from the programmed variables the computer (CR) activates controllers (RMY and RMX) which themselves act on the drive motors (MX and MY) for the sewing material, so that the adjustment of the sewing material can be matched to the best possible sewing or embroidering speed at every moment. <IMAGE>

Abstract: Existing air handling systems often incorporate an internal filter which tends to be poorly maintained due to it being located in an inaccessible region of the system where it may not readily be replaced or readily be inspected. A device for monitoring pollution in air flowing through an air handling system comprises a frame (2) and a filter (3) releasably mounted within the frame (2). The frame (2) is adapted to be mounted upon the periphery of an air inlet or outlet of an air handling system so that the filter (3) extends across the air inlet or outlet. The device is arranged such that when mounted in position upon the air handling system, the filter (3) may readily be inspected by occupants within a room in which the device is located and the amount of pollution on the filter (3) indicates the operating efficiency of the filter in the air handling system. If necessary the filter (3) may be quickly and simply replaced.

Abstract: Disclosed is a technique for providing solder bumps (15, 16, 17) to electronic components (10), such as silicon chips, chip carriers, and circuit boards, so as to achieve large stand-off heights. The component is covered with a mask (14), such as a photoresist, leaving exposed the solder pads (11,12,13) on the component. Solder is applied to the surface along with ultrasonic energy so that the solder wets the exposed pads. The mask acts as a mold for the solder, thereby producing. large solder bump heights.

Abstract: A switching system (10) including a number of switching modules (1000, 1020, 1050) each having a plurality of access ports (P1, P2, P9, P5). Incoming and outgoing packet channels (81, 82) are extended between each switching module and an inter-module packet switch (2012). Each of the switching modules includes both a packet switching unit (1400) and a circuit switching unit (1011) for switching information to and from the access ports. Each switching module further includes a control unit (1017) that controls the switching units and that generates inter-module conyrol packets, and a communication interface (1900) that transmits inter-module control packets generated by the control unit on the incoming packet channel to the inter-module packet switch.

Abstract: In the light system, particularly for the low-voltage region, the holders and supports for the lighting bodies consist of conductive material and at the same time form the electrical connection. Elements of non-conductive material are provided which split the complete light system into two electrical phases which are insulated from one another. In this way, a light system is produced which can be assembled in the easiest possible manner from individual components, and can be modified at any time, no connections via lead wires being required whatsoever. In this case, the components, consisting of conductive material, are at the same time used as electrical supply leads. Light systems of this type can be produced very cost- effectively despite providing the user with the maximum possible versatility.

Abstract: The method is based on negative deep-drawing and involves introducing the possibly restrained or pretensioned web into the female deep-drawing die and utilising a pressure difference as well as heating to deform the said web while maintaining a temperature difference, imparting to it a grained effect and/or surface decoration. The textured finish is produced by a female deep-drawing die having a porous, air-permeable, preferably microporous air- permeable die surface of ultrafine particles, in particular metal particles, of a thickness of less than 80  mu m. During thermoforming, the plastic web is given a textured and/or grained finish and thereafter or at the same time a treating agent is applied from the rear side of the plastic web. The treating agent is a cooling liquid or cold gas or an adhesion promoter, an adhesive, a plastic layer and/or a barrier layer. The female deep-drawing die is assigned a catching tray or a catching container, as well as nozzles, sprays or spraying devices, the opening and/or nozzle angle of which is directed at the cavity of the female deep-drawing die, intended for receiving the plastic web.

Abstract: An improved method and apparatus of forming and assembling two-part merchandise display hooks (10), including new design features of the hook (10) itself, enable two-part hooks to be manufactured and assembled at extremely low cost. Wire (88) from a continuous length is gripped and bent to form the outer portion of the hook (11). The wire (88) is then severed and bent in a single operation to form a hook-mounting portion (16). While the severed wire remains gripped by its shaped outer end, a preoriented and guided base member (12) is applied over the just-formed mounting portion (16) of the wire. A retractable bend-forming member (102) is withdrawn when the base member (12) is applied to the wire, to enable the bent portion (16) to be fully received within the plastic base (12). Major manufacturing economies are realized.

Abstract: A method is proposed of injection moulding hollow formed parts from thermoplastic resins in which first of all an amount of the molten resin sufficient for forming the part is forced into the injection mould. Then, a flowable medium, in particular gas, is forced into the injection mould and/or the thermoplastic resin at a pressure which distributes the resin compound evenly over the surface of the mould cavity, forming a hollow article. Thereafter, the hollow article is cooled in the injection mould whilst kept under the pressure of the medium. Finally, the hollow article is relieved of the pressure of the medium and then the formed part is released and removed from the injection mould. What is essential here is that the pressure of the medium within the injection mould, or on the resin compound distributed over the surface of the mould cavity, is varied at least for a time during its cooling, to be precise by closed-loop and/or open-loop control according to a pressure profile specified for the respective formed part and/or resin material.
