Patent DE-3108249-A1 (DE)
Title: Expansion clamping tool
Inventor: SCHUNK JUN FRITZ
IPC: B23B31/30
Filed: 1981-03-05
Abstract: In expansion clamping tools (11) having a basic body (12) and an expansion clamping bush (17), in which the expansion clamping bush (17) is deformed by the pressure of a fluid, there is the problem that, in the event of the pressure falling away on account of faults in the pressure-generating apparatuses or in pressure-carrying lines, a clamped workpiece can suddenly become loose. This is now avoided by the pressure required for clamping being applied by an elastic element (24) which presses on a pressure piston (22) guided in a pressure cylinder (23) in the basic body (12). A force which acts from outside via a counterforce mechanism and by which the pressure piston (22) is pressed back against the force of the elastic element (24) is then only required for the release. A pressure piston (22), on which the force of an elastic element (24) acts continuously and to which the force of a counterforce mechanism (45) can be transmitted, can be used in both expansion chucks and expansion mandrels. Expansion clamping tools of this type are used wherever quick and accurate clamping is required. <IMAGE>

Title: Shift key unit for power-driven typewriters or similar office machines
Inventor: SEFFNER JOACHIM
IPC: B41J5/20
Filed: 1981-04-02
Abstract: The aim of the invention is to allow an even keyboard operation for the operator whilst minimising the production outlay and expenditure and ruling out the possibility of faulty operation. It is based on the object of developing a shift key unit, in which only a brief shift key operation is required for triggering the shift whilst avoiding a shift key lever collar and, when it is cancelled, automatic triggering of the shift return is made possible, and in which the required key operation forces correspond only to those of the character keys. According to the invention, the shift key unit is characterised in that the shift key lever is provided with a first projection which triggers the shift lever and with a second projection which, via a latch, connects the shift key lever with rotary movement to the triggering latch, and the triggering latch can be adjusted by a coupler attached to it so that it operates a nose formed on the shift lever and tensions the leaf spring as a power accumulator for triggering the shift return. The invention can be used for power-driven typewriters or similar office machines. <IMAGE>

Title: Weft-thread insertion device for a jet-weaving machine
Inventor: KORIYAMA MASAYUKI
IPC: D03D47/30
Filed: 1981-04-03
Abstract: A weft-thread insertion device for a jet-weaving machine comprises a plurality of air-guide elements (3) having straight air-guide orifices (4) forming a thread-guide channel (4A), through which a weft thread (12) is inserted by a thread-inserting nozzle. Each air-guide element has a slot, through which the weft thread passes out of the air-guide orifice. Each air-guide element is at such a distance from the adjacent air-guide elements that the air-stream fractions escaping through the slots in the air-guide elements are cancelled by the air-stream fractions which flow out through the spaces between the air-guide elements. This affords a saving of compressed air and prevents the weft thread from executing fluttering movements and coming out of the thread-guide channel during the thread insertion. <IMAGE>

Title: Process for producing an interlocking masonry structure and masonry blocks which can be used for this purpose
Inventor: EJSKJAER KNUD JENSEN
IPC: E04B2/02
Filed: 1981-04-14
Abstract: The invention proposes a masonry block which is suitable for constructing a wall or the like and has a main surface (1) on which there are formed, at a distance from the edges of the masonry block, at least two elevated protrusions (2) and an opposite main surface (4) on which there are formed, at a distance from the edges of the masonry block, at least two corresponding recesses (5). The protrusions and recesses are arranged such that two masonry blocks of identical construction can be positioned with their ends one against the other and the protrusions uppermost and a third masonry block of identical construction can be positioned on the other two blocks, one or more of its recesses receive one or more of the protrusions of one of the two masonry blocks and one or more of its recesses receive one or more protrusions of the other of the two blocks, as a result of which the blocks are interlocked with respect to one another. The masonry block is characterised in that   i) the sides (6, 3) of the recesses and protrusions run essentially perpendicularly to the main surfaces, and ii) in that the recesses and protrusions are arranged and dimensioned such that, if the recesses are filled to the top with mortar and the masonry block is positioned, as above, over two masonry blocks of identical construction, a sufficiently large volume is displaced, with the result that a connecting location of predeterminable thickness is formed between the masonry-block courses.   <IMAGE>
