Title: Automatic ventilation system for shoe soles - has air chambers in heel, instep and toe area causing air flow during walking
Inventor: EICHEL ALFONS
IPC: A43B7/06
Filed: 1980-12-03
Abstract: The sole is ventilated by a mechanical deflection of the air flow which is operated when the heel meets the ground. The air is forced forwards from the air bellows in the heel so that it flows through a connecting passage and out into the cavities around the toes. The slightly larger volume of the air compensating chamber in the instep than in the air bellows in the heel causes the air to be pressed forwards and backwards as the foot rolls along. When the sole is no longer stressed this larger volume ensures air is drawn in.
Patent DE-3101788-A1 (DE)
Title: Spout, preferably a slag spout (launder) for blast furnaces
Inventor: PYSCHIK JOHANNES
IPC: C21B7/14
Filed: 1981-01-21
Abstract: The invention relates to a cooled spout (channel, launder) made of cast iron with embedded cooling tubes, which is preferably used as a slag launder on blast furnaces. The aim of the invention is to reduce the heavy physical work involved in the preparation of a slag spout on a metallurgical furnace and reduce the costs for its manufacture. The object of the invention is to find a spout for the removal of molten slag, in particular blast furnace slag or the like, which allows a considerably longer service life while using low grades of material and a simple design. The object is achieved, according to the invention, by virtue of the fact that, preferably in the region of the impingement of the slag stream on the spout, the spout consists of a casting with embedded cooling tubes. The cooling tubes are arranged in such a way in the casting that the coolant first of all flows through the area of maximum thermal loading, for which purpose a division of the cooling system into two cooling circuits is advantageous. The invention can be applied to metallurgical furnaces in which molten slag is encountered. <IMAGE>

Title: Method for printing or deleting underlined characters
Inventor: WEHKING HANS
IPC: B41J29/36
Filed: 1981-02-11
Abstract: In typewriters which are provided with a memory (2) and a control unit (5, 6) and have a type division of varying (e.g. proportional) or variable (e.g. adjustable 1/10'', 1/15'', 1/20'' division) size or have modes of operation which influence the type division, provision is made, in the case of automatic underlining of characters, for underlining lines of different length to be printed corresponding to the respective character and the division. After input of the character to be underlined, the length of the respective underlining line is determined by the control unit (5, 6) on the basis of stored data assigned to the characters. In this case, the smallest underlining length corresponds to the length of the line type on the type carrier (7) of the machine and the greatest underlining length corresponds to three times the line-type length. All the intermediate lengths required are produced by overlapping printing of the line type. A corresponding functioning sequence is also provided in the case of deletion operations, a correction ribbon (14) being used instead of an ink ribbon (13). <IMAGE>

Title: Shut-in grid for a herringbone milking parlour
Inventor: HACKER JOSEF
IPC: A01K1/12
Filed: 1981-02-11
Abstract: A description is given of a shut-in grid for herringbone milking parlours, in the case of which grid the upper part of one of the lateral delimitations is closed by a pivotable catching member. The catching members, with the exception of the rearmost catching member, can be locked. When the catching member is unlocked, the cow, making its way towards the bait feed, can pivot the catching member, by means of its head, into a position which is opened wide to such an extent that the cow can guide its head into the shut-in opening. The catching member then pulls back automatically into the next catching position. Unlocking of the next catching member in front can be triggered either by the pivot movement of the next catching member behind or by the actuation of a separate triggering bow.

Title: Drive for a roller shutter door
Inventor: PETERS JOSEF ING GRAD
IPC: E06B9/84
Filed: 1981-07-28
Abstract: The invention relates to a drive for a roller shutter door having an intercepting device preventing said door from coming down. The drive and the intercepting device are designed as a unit and comprise a worm and two worm wheels which mesh therewith and are connected to each other such that they are fixed in terms of rotation. The second worm wheel meshes with the worm such that, when the first worm wheel is driven by the worm, the second worm wheel runs along free of loading. When the drive of the first worm wheel fails owing to defective engagement, blocking takes place, however, between the second worm wheel and the worm or an outer stop against which the second worm wheel can move owing to a force component arising from the engagement between worm wheel and worm.

Patent DE-3151384-A1 (DE)
Inventor: REIZIG HANS-JUERGEN DIPL ING
IPC: B21B37/00
Filed: 1981-12-24
Abstract: The invention relates to a process for cropping the head of self-luminous rolled material, especially metal strips when it passes a rolling train. A line scanning camera is used for detecting the shape of the head by repeatedly generating optical images of the rolled material immediately downstream of the last roughing stand. The distance separating the cutting line from the beginning of the head is determined in accordance with the shape of the head. Immediately upstream a pair of shears the velocity and the beginning of the head are detected. A control signal for the shears is generated in accordance with the signals for the beginning of the head and for its velocity and with the distance of the cutting line from the beginning of the head. In order to detect the edges of the rolled material from the beginning of measurement even under wide variations of the radiation intensity the exposure time of the line scanning camera is controlled by a radiation-intensity measuring device in the sense of obtaining an optimum exposure in respect of the edges of the rolled material.

Title: Method and apparatus for producing, compressing and separating an inert gas
Inventor: WINTER KARL DIPL PHYS
IPC: B01J19/14
Filed: 1982-03-23
Abstract: During the further development of the invention according to P 3123530.1, it was found, surprisingly, that the performance achieved by a modern internal combustion engine is quite sufficient for it to compress its own exhaust gas to over 75 bar, which does require multistage compression and careful cooling and intermediate cooling. In the process, the critical pressure of carbon dioxide is exceeded, so that the carbon dioxide condenses and can then be separated from the remaining inert gas. It is thus very easy to obtain liquefied carbon dioxide and compressed nitrogen.

Title: End sleeve with fastening part for an armoured wire rope, and process for producing armoured wire ropes by means of this end sleeve
Inventor: GLASER NORBERT
IPC: F16G11/02
Filed: 1982-04-21
Abstract: Armoured wire ropes afford protection against being severed, for example by means of bolt cutters or by means of saws. The weak point of armoured wire ropes of this type is the end sleeve with fastening part, which is introduced into the lock and engaged. The production and attachment of end sleeves of this type and their hardening become possible in that the free end of the armoured wire rope (3) is introduced into a blind bore (12) of the basic body (10) of the end sleeve (1) and clamped, the end face of the end sleeve confronting the following armour sleeve of the rope being a spherical surface (11), the curvature of which corresponds to the curvature of the end face of the following sleeve (2.1). The two end faces bear against one another in the manner of a ball joint. The basic body (10), which consists of temperable, preferably case hardenable steel, has, at its other end, a fastening piece (4) which is designed correspondingly to the provided fastening as a lug, catch bolt or the like. For attachment, the end sleeve is decarbonised on its surface and heated approximately up to yellow heat, the wire-rope end is introduced and clamped together with the basic body, and immediately thereafter the basic body and the wire rope connected fixedly to the basic body are hardened by quenching. <IMAGE>

Title: Test-pattern changeover device for a quasi-random generator with multiplex-signal formation
Inventor: LEHMANN ERWIN ING GRAD
IPC: H03K3/84
Filed: 1982-05-28
Abstract: A quasi-random generator for high-rate digital test sets, which generates a quasi-random sequence that is a number of times faster, from a plurality of clock-phase-shifted quasi-random sequences, with the aid of a multiplexer, is intended to be provided with a test-pattern changeover device of economical construction. To this end, the quasi-random sequence changeover switch (Fig. 5, top) is implemented by means of suitable connection of integrated, emitter-coupled parallel shift-register modules, and the clock-phase changeover switch (Fig. 5, bottom) which is required for forming the multiplex signal is implemented by means of an integrated, emitter-coupled, triple 4-to-1 multiplexer module. There is in each case only one logic gate or multiplexer passage between two flipflop stages, and every connecting line originating from a module in each case leads to only one further module. The multiplexer bit rate which can be achieved in this way is more than 600 Mbit/s. <IMAGE>

Title: Thermodynamic converter
Inventor: JENSEN MICHAEL
IPC: F03G7/00
Filed: 1982-06-12
Abstract: The TDC can be constructed as a dynamic power station in the one watt to megawatt range. It operates with an efficiency of up to 100 percent. It is also capable in one function of using sources of relatively low thermal energy it converts directly into dynamic energy on the axis of the gas turbine: solar heat, atmospheric heat, water heat, ground heat, industrial waste heat, heat of oxidisation, heat from nuclear fission and nuclear fusion, and domestic waste heat. The TDC can be non-positively connected to a generator for producing current and to mechanical-pneumatic-hydraulic power transmission systems. Thus, as long as it is fed with heat, the TDC is a self-sufficient conversion unit which converts heat into mechanical energy and will compete with the conventional prime movers of all sorts and classes and one day replace them. The theoretical basis of the invention is the application of the observations of a natural world on which the so-called kinetic theory of gases and heat is based.
