Abstract: The invention concerns a gear unit (1) having a drive element (10) with a first tooth structure (11), an output element (20) with a second tooth structure (21), wherein the tooth structures (11, 21) are able to be brought into engagement cogging with each other to form a gearing in at least one engagement area (X) of the second tooth structure (21), and wherein the output element (20) has at least one uncoupling area (Y), in which the cogging engagement of the gearing is uncoupled. The invention provides that the first tooth structure (11) has at least one first modified tooth element (11a) and the second tooth structure (21) has at least one second modified tooth element (21a), wherein by a movement of the drive element (10), synchronization of the second modified tooth element (21a) with the first modified tooth element (11a) is possible in order to create a change from the uncoupled state to the engagement state.

Abstract: An auxiliary adjusting device for a rolling mill stand includes a adjusting shaft, a cylindrical member forming an adjusting spindle and having a first outer thread cooperating with the inner thread of a support sleeve fixedly connected to the cross-beam, and a central recess provided with longitudinal teeth, a carrier secured to a bottom of the cross-beam, projecting into the central recess of the cylindrical member, and carrying, at its end side, a tooth gear that functions as a planet gear that cooperates, on one hand, with a tooth gear secured at an end of the adjusting shaft which extends through the carrier, and serving as a sun gear, and, on another hand, with the longitudinal teeth of the central recess of the cylindrical member, and an adjusting pressure sleeve connected with the support sleeve for longitudinal displacement relative thereto but without a possibility of rotation relative thereto.

Abstract: A selector transmission for a motor vehicle in which two transmission shift positions G1, G2; G3, G4; G5, G6 situated in a shifting gate 55 of an H or multi-H shifting gate 51 within a transmission 1 can be respectively shifted via two different shifting sets 29, 30, 31, 32. The transmission 1 has one transmission input shaft 5, two countershafts 15, 16, one reverse gear shaft 22 and one transmission output shaft 28 available. The fixed and idler gears of each ratio step are positioned on the transmission shafts so that, departing from a single starting and separating clutch 4 of the transmission, the transmission gears are disposed in a sequence G2 and RG, G4 and G6, G3, G1, G5.

Abstract: A device for the back rounding of book blocks in a book binding machine cooperating with a conveyor device. The device includes a driving arrangement and rounding elements driven in rotation by the driving arrangement. The rounding elements taking up the book block following release of the book block by the conveyor device. The rounding elements acting on both sides of the book block through pressurized rotational movement thereof. When the book blocks are gripped by the rounding elements, the rounding elements may selectively travel in a lifting movement which is separate from the rotational movement into preselectable, defined vertical positions.

Abstract: An improved drive arrangement for a starter motor includes a rubber cushion between a drive plate and a pinion gear. The rubber cushion has seals at inner and outer locations which seal against the drive plate. In this way, the area between the drive plate and the rubber cushion is sealed to prevent contaminants from reaching the area and harming the connection between the drive plate and cushion.

Abstract: An oscillating rachet style continuously or infinitely variable transmission is disclosed herein, that is, one which, in its operation, relies on a plurality of different successive intermediate rotations that vary in speed and direction in accordance with their own respective oscillatory waveform, each waveform being out of phase with one another in a predetermined way. These intermediate rotations are used to convert the rotational input to a plurality of uni-direction output rotations, without the aid of any over-running clutches. These later outputs vary in speed in accordance with their own respective waveforms and are used to produce a modified rotational output.

Abstract: A motion transmitting remote control assembly (10, 10') including a conduit (12), and a motion transmitting core element (14) movably supported by the conduit (12). An adjustment device (18, 18'), comprising first (20, 20') and second (22) members, is provided for adjusting the effective length of the core element (14). The first member (20, 20') and the second member (22, 22') include coacting ratcheting teeth (36, 38) to limit relative motion between the first (20, 20') and second (22, 22') members to one direction. The first (20, 20') and second (22, 22') members have elliptical cross sections with the first member (20, 20') being molded of a rigid organic polymeric material. The second member (22, 22') is molded of a resilient organic polymeric material for deforming inwardly along its major diameter in response to a pinching force applied thereto, and outwardly along its minor diameter to disengage the ratcheting teeth (36, 38) allowing relative longitudinal movement in both directions.
