Abstract: The slidable member of a control device for an automobile heating and/or air conditioning installation extends through a linear opening of a control panel, this opening being obturated by a deformable tape which is fixed at both ends in such a way as to form two terminal loops extending from either end of a central portion of the tape. This central portion is movable longitudinally along the linear opening in the panel, and has a hole through which the slidable member extends, so that when the latter is slid along the opening, the central portion of the tape is moved with it so as to expand one of the loops and contract the other.

Abstract: A rod seal for establishing a seal between an elongate rod and a housing wall around an enlarged opening in the wall through which the rod projects provides a close fitting sliding seal between the rod and the seal to accommodate longitudinal reciprocation of the rod relative to the seal and housing and also provides a sliding seal between the seal and housing wall to accommodate lateral movement of the rod relative to the housing. The sleeve is of a two piece construction which is assembled by a snap fit after the rod has been inserted into one element of the seal so that an enlarged end of the rod may be passed through an opening in the one seal element and the subsequent assembly of the second element achieves a close sliding fit with the unenlarged diameter section of the rod.

Abstract: An improved sealing and attachment means between a rubber boot (20) for a powdered door lock (4) and its actuator rod (10), which allows, not only radial, linear movement of the rod with respect to its power motor, but also rotational movement of the rod within its attachment to the boot, allowing such rotation without significantly distorting the boot. Two, axially spaced grooves (13 & 14) are located on the exterior surface of the rod at the area (15) to which the boot is to be attached, while two longitudinally spaced annular beads (22 & 23) are provided on the interior surface of the end portion (21) of the boot, which beads will be located between, but not in, the grooves. Two ring clips (16 & 17), serving as radially extended retainers, are placed in the rod grooves, fixedly positioning the attachment end portion of the boot longitudinally between the grooves. A gap (18) allows the ring clip to be laterally clipped onto its respective groove.

Abstract: The invention relates to the production of a guidance system (9, 14) for two machine parts (1, 2) which are movable relative to each other and are interconnected through this guidance system. To protect this guide track (9) disposed on the first machine part (1) from the track dust, grease, oil and the like, it is disposed in an almost completely closed guide channel. This guide channel is accessible only from the top through a slot engaged by guide elements (14) of the other machine part (2). The slot is covered on the one hand by the housing of machine part (2), and in the area outside of this housing it is closed by a belt (4). The guide track (9) is thus closed to the outside in any position of the machine part (2). If a toothed belt drive (3) is used, the toothed belt (4) acts as driving and covering element at the same time.

The center of radius of adjacent spherical surfaces alternates between a point on the shift lever determined by the distance between the boot apex and the lever pivot joint and a point on the shift lever at the boot apex. The smaller radius spherical surface is co-tangent with the larger radius spherical surface immediately adjacent thereto and displaced therefrom toward the pivot joint.
