Abstract:
At least one slide block is installed on the saddle pole for optimal guiding, as far as possible free of play, of a saddle pole in a cladding tube, at the lower end of the saddle pole. The slide block(s) engage in a groove-shaped recess in the cladding tube, said groove-shaped recess of the cladding tube having at least one length, which corresponds to the requested adjustment stroke of the saddle pole. At least one contact surface of the saddle pole, on which a planar slide block is installed, is planar and the side of the planar slide block, which is installed on the saddle pole with the planar contact surface, also has a planar surface.

Abstract:
The invention relates to a height adjustable saddle pole consisting of two tubes which are telescopically slidable into another, that is to say a cladding tube for accommodating a saddle support tube, whereas the saddle support tube is spring-loaded and is fixed in position via a locking pin. The bores into which the locking pin engages, are located in the region of the smallest stress of the saddle support tube in order to weaken the static of the saddle support tube as little as possible.
Abstract:
Process for preparing propene oxide, in which a mixture of propene and oxygen or an oxygen-containing gas is reacted at a temperature in the range from 150 to 500° C., in the presence or absence of a catalyst, in a reactor, wherein all or part of the interior of the reactor is lined with inert materials. The inert material used is at least one of the materials of the following group: one or more noble metals of transition group VIII of the Periodic Table, in particular gold, titanium and tantalum, glass, enamel, quartz, ceramic and Teflon. The selectivity to propene oxide is >60%.
Abstract:
An apparatus and and a method for merging streams of presorted pieces provided with addresses into a row of pieces in accordance with a predetermined sequence of possible addresses, starting from at least two presorted rows in which the pieces are sorted in accordance with the predetermined sequence. The apparatus includes receiving elements which are transported successively along a conveying path, and transfer devices arranged at transfer points along the conveying path, wherein the number of transfer devices is equal to the number of presorted rows. The receiving elements are conveyed past the transfer devices in a timed sequence determined by the transport along the conveying path. The transfer devices can be actuated selectively for transferring a sorted piece each from the respective presorted row into one of the receiving elements as the receiving element travels past the transfer device. The apparatus further includes a control device for actuating the transfer devices in a timed sequence in which the pieces of all presorted rows are arranged in the receiving elements in accordance with the predetermined sequence and which is adjusted to the timed sequence of the transport of the receiving elements past the transfer devices.
Abstract:
An arrangement for feeding a conveying apparatus comprising hoppers for flat products such as envelopes, mailing pouches, workpieces and the like, which can be emptied at certain intervals and are secured on a rotatably driven traction element. A device including a slanted guide wall defining a conveying channel is located above the conveying apparatus for conveying the products in a conveying direction into a respective one of the hoppers located below the conveying channel. The device includes a size intake opening communicating with the conveying channel for receiving products into the conveying channel from a side of the device in a direction at a right angle to the conveying direction. The device further includes a rotating clearing mechanism laterally penetrating the conveying channel and operating jointly with the guide wall for conveying the products into the hoppers.
Abstract:
A tiltable bowl of a carriage of a sorting line is secured on two supports which are arranged axisymmetrically with respect to one another. The supports are pivotably seated on an axle. On each support, a resilient yoke is formed on one side with its first end. The oppositely disposed second end of the yoke can be displaced within defined limits relative to the supports. Each yoke has a latch cam which, in the horizontal, initial position of the bowl, locks into place behind a projection fixedly connected to the frame and thus locks the bowl in this initial position. When a pusher rod articulated at the second end is pushed upward, the lock is released first and then the bowl is tilted.
Abstract:
For use in the graphiting of carbon bodies, a graphiting furnace is proposed, which contains inert gas and in which carbon bodies forced together to form a train are fed in feeding steps. The train is axially gripped to set up therein an axial compressive stress which is sufficient to render the train self-supporting. That axial compressive stress is also maintained while a graphited carbon body is removed from the train and a carbon body to be graphited is added to the train between consecutive feeding steps.
Abstract:
A safety helmet, in particular for cyclists, includes a self-contained portable semi-shell helmet (H), on which an integral part (1) enclosing the chin and the occiput/neck area can be fixed in a detachable way. The semi-shell helmet (H) is equipped as a self-contained helmet with a chin strap fastening and all that belongs to known helmets, This hence enables, depending on the intended use, only to wear the upper helmet part or the assembled integral helmet.
Abstract:
For processing sorted goods, in particular for processing mail pieces in postal facilities, an apparatus is proposed for transposing address-bearing sorted goods into an ordered sequence according to a predetermined order of possible addresses, starting with two supplied partial sequences in which the sorted goods are already ordered according to the predetermined order of possible addresses. The apparatus includes a number of actuable transfer devices equal to the number of partial sequences for sequentially transferring the sorted goods of a respective one of the partial sequences to a selection unit. The selection unit is actuable for selectively receiving sorted goods from all transfer devices and for conveying the received sorted goods to a delivery point common to all sorted goods. For this purpose, the selection unit is actuated by a controller for recording the addresses of the sorted goods to be transferred.
