Abstract: A tuft picker device for a brush making machine has a bristle magazine for holding a supply of loose bristles and a tuft picker having a tuft picking notch being movable past an open side of the bristle magazine in a working stroke. A shield member is adapted to be shifted across the tuft picker notch to change the effective depth thereof. The shield member can be adjusted by an adjusting device in each working stroke in order to vary the effective depth of the tuft picking notch from one working stroke to the next to change the size of a tuft engaged in the notch.

Abstract: A method of replacing an electrical insulator on a conductor-supporting tower includes the steps of providing an elongate beam spanning the tower between a work site and a helicopter accessible site, a trolley movable on the beam between the sites and an insulator cradle detachably supported by the trolley for supporting the insulator during transport between the sites and to and from the tower via helicopter. The cradle is a partially peripherally enclosed, open-topped structure having a floor, an upstanding rear wall, peripheral walls sloping downwardly from the rear wall to a front wall, an opening in the front wall, an elongate slot in the floor extending rearwardly from the opening, the slot having a width greater than the diameter of an insulator shank but less than the diameter of an insulator skirt, the dimensions of the floor allowing an insulator skirt to lie flat thereon.

Abstract: In a pay television system, the choice and the confirmation of an impulse purchase are performed by the user on presentation, by means of a screen, of a grid of programmes. The selection by this user of a particular programme of his choice from the grid is subsequently confirmed in the system by an entitlement management message, this message being specific to an impulse purchase. In order to authorize the immediate screening of the selected transmission, the entitlement management message specific to an impulse purchase is contained in the data tied to the presentation of the grid.

Abstract: A modular occupant bench unit for use in a swimming pool formed from a plurality of contiguous modular wall panels joined end-to-end to define a pool enclosure having a vertical perimeter wall includes a vertical wall having opposite ends adapted to be joined with contiguous wall panels and being substantially coplanar with the vertical walls of the wall panels and an elongate bench protruding from the vertical wall between the top and bottom thereof into the pool substantially beyond the plane formed by the vertical wall of the pool, the upper side of the bench defining an occupant seating area and the underside being spaced from the floor of the pool. A plurality of hydrotherapy jets are spaced apart along the vertical wall above the upper side of said bench and below the water line of the swimming pool.

Abstract: In a conditional access network a provider distributes valuable contents such as digital TV over the network and end-users are allowed to access such valuable contents in function of individual access rights defined by a user license. The valuable contents are made available to the end-users, by way of a plurality of different conditional access systems, each end-user is provided with a generic conditional access component having a basic functionality common to all conditional access systems, and particular conditional access systems are selectively enabled on each conditional access component subject to a successful verification of a corresponding license.

Abstract: A transfer platform for safely transferring a lineman from a helicopter to a utility pole includes a cylindrical hollow member dimensioned to closely fit over the top of the pole, the member having an open lower end and a top cap closing the upper end thereof, the top cap abutting the top of the pole when the member is positioned on the pole, a step extending sidewardly from the member, the step being substantially parallel to and lower than the top cap and an equipment support assembly extending sidewardly from the member. An aperture is formed in the member beneath the underside of the step and an adjustable shim assembly extends through the aperture into the hollow of the member.

Abstract: A modular system comprises a head module having at least one connection for an external bus signal on an external bus, at least one pneumatic supply connection, an electric supply connection and having a serial bus interface for an internal serial bus, an electric supply interface, a multipole interface and a pneumatic supply interface which are each led to the outside on the same side. The modular system further comprises at least one functional module having an internal serial bus line, electric supply lines, electric multipole lines and pneumatic supply lines which are each passed through from one side to the opposite side and which are each connected to a corresponding interface of the head module. The head module here converts serial bus signals into multipole signals and outputs these signals at the multipole interface.

Abstract: A brush stuffing machine comprising a bristle magazine and a stuffing tool which is movable between a bundle take-over position and a stuffing position, the stuffing tool is pivotally mounted about an axis for movement on a circular arc between the take-over position and the stuffing position.

Abstract: There is described a method and an apparatus for the optical 3D digitization of bodies and body parts which reveal non-visible regions which therefore cannot be detected by the 3D digitizer. A mechanical aid is fixed at these regions and protrudes into the measurement space visible for the 3D digitizer. On this visible part, it is provided with marks and is digitized together with the remaining, visible body parts. From the spatial position of the marks of these aids, important geometrical information of the non-visible parts, such as the spatial position, circumferential dimensions, etc., can be calculated, and the 3D model of the body or body part incomplete at these points can be completed therewith. Two applications from the field of orthopedics are described by way of example.

Abstract: A bristle magazine for a broom or brush stuffing machine includes a receiving space for a multitude of bristles, a bending edge and a bracket opposite the bending edge for maintaining the bristles in a curved condition.

Abstract: A mounting assembly for rotatably mounting a surface processing tool holder on at least one motor driven rotatable arm of a surface processing apparatus, such that the tool can spin freely as the arm is driven by the motor, includes an elongate shank having a smooth surfaced, cylindrical portion intermediate its ends adapted for positioning within an aperture in the tool holder with one threaded end portion projecting through the aperture for attachment to an elongate mounting bar adapted for attachment to the arm. A bearing supported by the tool body and surrounding the smooth surfaced portion of the shank is rotatable relative to the shank. The mounting bar includes a threaded aperture for receiving the threaded end portion of the shank and the threaded aperture includes a counterbore for receiving the end portion of the smooth surfaced shank portion which is adjacent the threaded end portion.

Abstract: In a device for reversing the flow of flowing media including two multi-way valves (21) which are fluidically interconnected and mounted on an adapter plate (32), the two valves are identical and are fluidically connected with one another by being pushed one into the other via rotationally symmetrical sealing members that seal in the radial direction.

Abstract: At the moment of the diffusion of Pay-TV with multi-channel signals, each channel is associated to authorization messages (ECM) which allow to decrypt this channel according to the rights of the subscriber. When changing channel, a very short time is accepted before one has determined these new rights in relation with the new channel. The heavy encrypting algorithms are thus excluded. To avoid this drawback, to decrypt a channel, a system is proposed using the combination of the authorization information for a channel (ECM), and thus encrypted by a fast algorithm, with authorization information (MECM) for a group of channels. These latter are encrypted by a high security algorithm and are thus slower to decrypt.
