Patent DE-3721729-A1 (DE)
Title: Weldless chain-link pairing
Inventor: ASBECK HEINZ
IPC: B21L99/00
Filed: 1987-07-01
Abstract: The chain-link pairing consists of a C-shaped hook-in link 1 and a ring link 2. On the hook-in link 1, a blocking nose 17 is provided on the inside of the link web 11, and, on the ring link 2, a coupling groove 20, which is matched in terms of its outline with the blocking nose 17, is provided on one side. The blocking nose 17 forms a peripheral region of the swivelling supports 15 in the hook-in link 1 so that a ring link 2 can only be introduced into the swivelling supports 15 and released from the latter when the ring link 2 and the hook-in link 1 are positionally oriented with respect to each other in terms of the blocking nose 17 and the coupling groove 20 such that the blocking nose 17 engages in the coupling groove 20. Instead of a web-side blocking nose 17, additional fin-like blocking noses can also be provided on the legs 13. In this case, the ring link 2 also has two coupling grooves situated opposite each other. In addition, a securing clip can be fitted in a form-fitting manner into the hook-in opening 14 of the hook-in link 1. Furthermore, instead of a C-shaped hook-in link 1, a hook-in link 1 which has only one swivelling support 15 and has, at the other end, fastening or suspension means can also be used. <IMAGE>
Patent DE-3723012-A1 (DE)
Inventor: MORIGUCHI HARUHIKO
IPC: G03F7/00
Filed: 1987-07-11
Abstract: A dye transfer imaging method uses a transfer sheet provided with a sublimable dye whose vapourisability changes when placed under the simultaneous influence of two different forms of energy input. Subsequent transfer of dye to an image receiving substrate is therefore modulated by whether or not selected areas have been so influenced. The influences may be both heat and light, and in a multi colour embodiment each dye is selectively sensitive to a respective light source colour. In a three colour apparatus (Fig. 2) the transfer sheet 1 is passed via imaging (3) and transfer (4) stations. At the imaging station a thermal recording head 3b (of known kind) acts in coordination with three light sources (3c, 3d, 3e) to differentially selectively inhibit the vapourisability of three sublimable dyes. At a subsequent transfer with hot roller 4a, a three colour image is transferred in one step. At the transfer station the transfer sheet and imaging substrate may be in contact or slightly separated. The formulations of various examples of transfer sheet are given. <IMAGE>

Title: Regulated short-term energy source
Inventor: SCHOLZ LEO
IPC: B23K11/26
Filed: 1987-07-22
Abstract: Short-term welding timers, for example, are used for welding or silver-soldering miniature contacts onto a carrier. Extremely short energy pulses can be supplied using the short-term energy source according to the invention. Such energy pulses must have a combination of an extremely steep-edged rise (20) and a subsequent horizontal response (30). This is enabled by the described apparatus in that the buffer storage of the energy is carried out in at least two mutually decoupled capacitors (3, 4). A major advantage is at the same time that the power loss on the actuating element (9) is low. Such a short-term energy source is able to supply an energy pulse which has a value of at least 10 A/ mu s during the rise and supplies a current intensity of at least 3 kA during the subsequent horizontal response. <IMAGE>

Title: Process for repairing a buried pipeline
Inventor: MUELLER HANS
IPC: F16L55/165
Filed: 1988-01-20
Abstract: With the destruction of the old pipeline (11), the intention is to achieve that the replacement pipeline, formed from pipe pieces (17), can be set up without any problems, even if the old pipeline (11) lies within the groundwater and/or if the penetration of fine particles (grit and sand) is to be expected and no point loads are to arise in the annular space between the new and the old pipes. A sealing hose (13) is drawn into the old pipeline (11) before the latter is destroyed, which sealing hose is calibrated (sized) by the rupturing apparatus (14) and encloses the replacement pipe formed from the pipe pieces (17). The process according to the invention is suitable particularly for repairing sewer ducts without any great amount of earthwork. <IMAGE>

Title: Device and method for optical reflection measurement on coloured objects
Inventor: KRZYMINSKI HARALD DR ING
IPC: G01N21/47
Filed: 1988-02-18
Abstract: The device is specified for optical reflection measurement on coloured objects and is designed in the form of a one-piece housing (1) containing a current source and having a measured value display area.

IPC: C23C18/02
Filed: 1988-08-18
Abstract: A coating film of titanium oxide having a controlled thickness and good optical characteristics is formed by using a 0.2-0.8 mol/l solution of a Cl-containing titanium alkoxide represented by TiCl4-x(OR)x, wherein R is a C1 to C10 alkyl or alkoxyalkyl group and x is not smaller than 2.5 and not larger than 3.5, in an organic solvent and in which the concentration of said alkoride is 0.2-0.8 mol/l. The alkoxide solution is applied to a substrate by, for example, spin coating or dip coating, and the liquid coating film on the substrate is dried at 200-300 DEG C. The wet coating and drying process is repeated at least once more until the resultant coating film acquires a desired thickness. Then the dried coating film is baked at a temperature not lower than 400 DEG C. In the same manner, a coating film of a mixed oxide of Ti and Si, Al or Zr is formed by using a solution of the Cl-containing titanium alkoxide and an alkoxide of Si, Al or Zr or its hydrolysate. In the mixed alkoxide solution the molar ratio of Si, Al or Zr to Ti is not greater than 1.2:1, and the total concentration of the alkoxides or its hydrolysate is 0.2-0.8 mol/l. The substrate is preferably glass or a ceramic. The film may be employed as a reflective film, a coating for a nonreflective glass or a coating for a head-up display.

Abstract: The aim in relation to an arrangement for cooling power semiconductors, in which the dissipation of heat is performed by an insulated, water-cooled heat pipe, is, in particular, to further improve the heat transfer on the condensation side and thus the cooling efficiency. This object is achieved by making use of a multipartite heat pipe, which acts in an electrically insulating fashion in the longitudinal direction and has terminal metal pipe structures (1, 2) which are located at heat source and heat sink and are electrically insulated from one another by a tubular insulating member (3) and by providing that a water cooling system dissipates the heat directly from the metal pipe structure (2) of the heat sink. It is advantageous for service water to be used and for the water cooling system to be connected to vehicle frame (earth). <IMAGE>
