Abstract: Support beams 13, 13', which run parallel to the plane of symmetry (s-s) and which extend as far as the rear end of the drive device of the tool locking unit, are situated above the tool locking unit of the plastic injection-moulding machine. A pallet, the injection-moulded part-receiving surface (55a) of which is designed to receive the injection-moulded parts in the setting position, is located above the drive device and between the support beams 13; 13'. The injection- moulded parts can be moved into their setting position by means of two slides (A; B) which can move horizontally and vertically relative to each other and which can be driven via flexible elements. By virtue of such a design it is possible for even sensitive injection-moulded parts to be removed from the injection-moulding mould, deposited and conveyed away in an equally quick and careful manner.

Title: Electrophotographic selenium photoreceptor
Inventor: KASAHARA MASAHIKO
IPC: G03G5/082
Filed: 1989-02-14
Abstract: In order to increase the life, measured in the number of printable copies, of an electrophotographic selenium photoreceptor used in an optical printer or a copying machine, the receptor has a coating layer as the outer layer of a laminate comprising a conductive base, a charge-carrier transport layer comprising amorphous selenium or an amorphous Se/Te alloy, a charge-carrier production layer comprising an amorphous Se/Te alloy containing from 20 to 50% by weight of tellurium, and the coating layer. The life of the coating layer is extended by increasing the As concentration in the outer coating layer. Greatly differing coefficients of thermal expansion between the charge-carrier production layer and the coating layer mean that cracking can occur. In order to prevent this and simultaneously to extend the life of the photoreceptor, the outer coating layer is in the form of a two-layer structure, where the inner or lower layer adjacent to the charge-carrier production layer has a lower arsenic content than the outer surface layer, the thickness of the outer surface layer being greater than that of the lower layer and being not more than 8  mu m.
Patent DE-3906807-A1 (DE)
Inventor: JUNKER WILHELM
IPC: E01F9/692
Filed: 1989-03-03
Abstract: The marker base comprises a baseplate and an insert part (22), for example in the form of a base body. The insert part (22) is received by means of a holder of the baseplate, which has two diametrically disposed groove-and-tongue connections (31). Its grooves (32) are arranged on an insert (25) of the baseplate. The tongues (33) are arranged on an insert shoe (34) into which a shank part of the insert part is inserted and guided in a rotatable manner therein. The shank part projects downwards out of the insert shoe (34). A securing pin (42) is inserted into a transverse through-hole in this longitudinal section. It has length greater than the width of the insert shoe (34) and of the insert (25). The opening in the insert (25) for the insert shoe (34) has a length greater than the length of the securing pin (42). Provided at the lower edge of the transverse walls of the insert (25) in the swivel plane of the securing pin (42) are two first recesses. Each of these are adjoined by a respective second recess arranged in the transverse direction of the insert (25) and closed off at the top. The inset part (22), with the longitudinally oriented securing pin (42) together with the insert shoe (34), is inserted into the insert (25) until the securing pin (42) is at the level of the first recesses. Then, the insert part (22) is turned through 90 DEG , so that the securing pin (42) is swivelled into the first recesses until it is in vertical alignment with the second recesses. If the insert part (22) is run over and the springs (33) on the insert shoe (34) are sheared off at the same time, the insert part (22) is raised. Moreover, the securing pin (42) is drawn into the second recesses, as a result of which the insert part (22) is secured on the baseplate. <IMAGE>

Title: Drive arrangement for a camshaft of an internal combustion engine
Inventor: HANNIBAL WILHELM DIPL ING
IPC: F01L1/344
Filed: 1989-06-06
Abstract: A drive arrangement for a camshaft 2 of an internal combustion engine has a device for rotating the camshaft 2 relative to a driving gear 5. The said device has a control sleeve 11, arranged coaxially with respect to the camshaft 2 and axially displaceable between two limit positions, which sleeve is connected on one side by way of helical teeth 12, 13 to the driving sleeve 5 and on the other by way of straight teeth 15, 16 to the camshaft 2. In order to obtain a space-saving arrangement and to create a facility for equipping one and the same cylinder head either with a conventional camshaft or with a camshaft drive with variable valve timings, the camshaft 2, in the direction of the driving gear 5, terminates after a cam 3a and the bearing point 9, which in a conventional camshaft serves for supporting said camshaft between the last cam and the driving gear, is used for supporting the boss part 7 of the driving gear 5. On the other side the driving gear 5 is supported by way of a second boss part 8 in an additional bearing point 10 in the cylinder head 1, the bearing opening of which is closed off by a cover when a conventional camshaft is used. <IMAGE>
Patent DE-3919522-A1 (DE)
Inventor: NADE ANDRE
IPC: F24D10/00
Filed: 1989-06-15
Abstract: In a district heating pipe with an interior tube (2) and an outer tube (3), and with a vacuum in the annular space (4) between the interior tube (2) and the outer tube (3), the annular space (4) is partitioned (5-7) at, for example, intervals of 500 to 600 m. The partition (5-7) is bridged by a line (9) which can be closed by a motor-operated valve (13) controlled by a pressure switch (11). If the pressure in the annular space (4) rises as a consequence of a leak, the bridging lines (9) are closed when the pressure increase has reached the threshold value of the pressure switch (11). The further increase in pressure is thus restricted to that section of the district heating pipe in which the leak has occurred. In a control room, to which the data from all partitions in the district heating pipe are transmitted, the section affected by the leak can immediately be identified. The damage is thus restricted and can rapidly be corrected. <IMAGE>

Title: Tumbler lock with sliding bolt and latched pin - uses coded card to energise opening and closing electromagnets as alternative to unlatching by mechanical key
IPC: E05B47/00
Filed: 1989-07-01
Abstract: The pin (3) on the sliding bolt (2) is prevented from moving, in the locked position, by a latching element (4) for which two independently operable unlocking arrangements are provided. One of these involves two electromagnets (6,7) actuated by a coded card for release and re-engagement of the latch. The other arrangement uses a key and a slider (9) working with the tumblers (13) to move the latch away from the pin (3). USE/ADVANTAGE - In e.g. banks and safe-deposits. The lock can be opened without its keys, but only by the person owning or renting the facility.

Title: Fusing together high and low m.pt. materials - by scattering over base and heated by radiation or HF etc.
IPC: B29B13/02
Filed: 1990-07-07
Abstract: Materials are fused together without having to cool the low melting pt. material to a very low level beforehand or shock cooling the sintered prod. The high melting pt. material particles are scattered over a base and are heated by radiation or h/f etc. without being moved; heating is then stopped and the particles of the low melting pt. material are distributed on and between those of the other material. When the low melting pt. material has been fused thereby further high melting pt. material is applied and fused to the low melting pt. particles beneath and the system is allowed to cool or is cooled by an air current. ADVANTAGE - The method eliminates the deep freezing and expensive stages concerned in the previous method which is covered by DE 36 04 447.
