Title: Auxiliary circuit connection for push-in apparatuses
Inventor: KRAFFT HENNING DIPL ING
IPC: H02B11/00
Filed: 1988-10-10
Abstract: The invention is based on the object of creating a reliable auxiliary circuit connection for push-in technology using movable main contact supports, which connection does not influence the installation of the push-in units. This object is achieved according to the invention in that the auxiliary circuit connection consists of a female connector strip (1) which is arranged on the side wall (3) of the push-in unit support and can be raised and lowered, a male connector strip (2) which corresponds thereto and is mounted rigidly on the push-in apparatus (4), and a lever mechanism (5, 6, 11, 12) for lowering and raising the female connector strip (1) as a function of the OFF-TEST-ON operating positions of the push-in apparatus (4). The invention is used for auxiliary circuit connections on push-in apparatuses which are hinged on a main contact support which can be moved in the push-in unit support, by means of which the main circuit connections are produced between a stationary push-in apparatus and busbars in the switch cabinet. <IMAGE>

Title: Temporary support for underground roadways
Inventor: RADTKE JOHANNES
IPC: E21D19/04
Filed: 1989-02-28
Abstract: During driving and support work in underground mining and tunnelling, it is of the greatest importance that the highest possible margin of safety is maintained and that an economical result is achieved. For this reason, special attention is paid to a temporary support which on the one hand permits forepoling and shielding of all exposed rock areas and on the other hand guarantees the sequence of various operations in overlapping or parallel form. To this end, the invention provides for a light support profile (4) which can be composed of sections and can be adapted at least partly to the rock. The sections (5) of the support profile (4) are designed in such a way that they can be connected to one another in an articulated, interlocking manner and can be made rigid (Fig. 1). <IMAGE>
Patent DE-3907265-A1 (DE)
Title: Answering machine
Inventor: MITTELSTAEDT RAINER DIPL ING
IPC: G11B15/66
Filed: 1989-03-07
Abstract: Answering machines with tape stores designed as cassettes have the disadvantage that a step formation is produced due to constantly repeated operations and shortcomings in the tape guidance in the tape spools in the answering and recording cassette, which may impede the tape movement or damage the tape. This is intended to be prevented in the novel answering machine. For this purpose, the novel answering machine has a counting device which counts the number of announcement cycles and/or the number of received calls without call recording. When the counting device reaches a pre-defined number, the device for controlling the tape transport receives a control signal which initiates first the forward winding and then the rewinding of the tape of the announcement and/or recording cassette in order to wind the tape first in the forward and then in the reverse direction, and returns the tape to its initial position once it has wound through. Answering machine with tape store.

Title: 6-Acyl-oxy-2-naphthoic acids prepn - by oxidn. of 6-acyl-oxy-2-naphthalene in anhydrous acetic acid, with manganese- and opt. cobalt-ions as catalyst
Inventor: ROEHRSCHEID FREIMUND DR
IPC: C07C69/017
Filed: 1989-06-26
Abstract: 6-Acyloxy-2-naphthoic acids of formula (I) are prepd. by oxidising a cpd. of formula (II) with O2, in anhydrous acetic acid, at raised temp. and pressure, in presence of Mn ions, or Mn and Co ions, as catalyst. R1 = 1-5C alkyl; R2 = H or 1-5C alkyl. USE/ADVANTAGE - (I) are used in prodn. of polyesters with good properties. Tough liq. crystals are formed by mixts. of (I) and 4-acyloxybenzoic acids. Oxidn. of the acyl gp. -CO-CH2-R2, when R2 is alkyl, gives the acid R2COOH instead of water. If R2 = H, formic acid is formed and is oxidised further to CO2 and water.  Less acetic acid is oxidised to CO2 and water than when the catalyst contains Br ions. (I) crystallises out on cooling, and is easily removed, e.g. by filtration, when the liq. can be reused.

IPC: B65G17/12
Filed: 1989-07-06
Abstract: The multi-stage conveyor has four continuous chains (7,8) such like running in pairs on two vertical, spaced apart planes.

The size of the stop-blocks (23-29) in the direction of the support-chain (17) is double the distance between the chain-bolts. Across the direction of the support-chain (17) the stop-blocks (23-29) have two holes (59,60) into which fit the two adjacent chain-bolts with their extensions. USE/ADVANTAGE - The multi-stage conveyor can support heavy loads and is simple in design.
Patent DE-3924815-A1 (DE)
Title: Sensitiser for photo-oxidative reactions - contg. formed, polymerically bound, photosensitive dyes
Inventor: WOLTERS WERNER
IPC: C09B67/08
Filed: 1989-07-27
Abstract: A sensitiser (I) for photooxidative reacns.  is claimed. The photooxidation occurs under the influence of a singlet which is produced from paramagnetic molecular oxygen by irradiation, in which an energy transfer through the sensitiser consists of formed, polymerically bound, photosensitive dyes. The novelty is that the dyes are used as polymerically undissolved solid particles (3,4) of grain size of not more than 1 mciron, and are evenly distributed in the polymer (5).  The prodn. of (I) is also claimed. USE/ADVANTAGE - (I) is used for the therapeutic purposes because the dye particles have a fixed bond in the polymer and can be used in lower concns. and lower toxicities.  The activity of the catalyst is improved, thus low amts.  of photosensitive dyes are required to produce singlet-oxygen at a higher rate of formation.

Title: Drying timber warping preventing structure - uses inserts less affected by moisture alteration than main portion in sap wood side
Inventor: KOIVUSALO VILHO
IPC: B27G1/00
Filed: 1990-03-16
Abstract: The structure prevents warping of sawn timber at right angles to the grain when drying, with one face (2) formed by the heartwood and the opposite one (3) by the sapwood.
