Title: Mould device for manufacturing concrete parts
Inventor: KRAISS RICHARD
IPC: B28B21/16
Filed: 1983-02-03
Abstract: A mould device for manufacturing in particular concrete pipes is proposed, which has a mould casing, a mould core which is placed exchangeably on a central vibrator, as well as an upper muff and a lower muff. Between the central vibrator on the one hand and the inner mould core on the other hand, there is provided a rotary bearing in the form of at least one roller bearing which allows relative rotary mobility between both parts in both circumferential directions. The rotary bearing can be locked or freed by a coupling device with locking element. The inner mould core is also alternatively drivable via a connectable, steplessly adjustable drive, the direction of rotation of which is reversible. The mould device makes possible improved compaction of the concrete in the case of unreinforced and in particular reinforced concrete parts, in particular also those with external contours which are not rotationally symmetrical. Moreover, better adaptation to the shape of the concrete part and also the concrete mix is possible.

Patent DE-3314847-A1 (DE)
Title: Process for the fabrication of seamless rings having improved spring properties
Inventor: THIEME ULRICH DIPL ING
IPC: C21D9/02
Filed: 1983-04-23
Abstract: The process for the fabrication of seamless rings having improved spring properties relates to the production of annular springs or annular elements of steel, in which the spring action is accomplished by elastic changes in the diameter of the rings. The aim of the invention is the application of a combined deformation and heat treatment technology which, at reduced fabrication cost, leads to an improvement in the use properties of the spring rings. The invention is based on the object of creating unfavourable recrystallisation conditions by means of a suitable deformation/temperature/time regime, so that improved spring properties result by interaction with the martensite transformation. The object is achieved by reaching, by means of a combined thermomechanical treatment (hot-forming of the stable austenite and cold-forming of the tempered martensite), a structural state of the spring steel which is characterised by greater elastic deformability and reduced cracking tendency under static and dynamic stress. The invention can be used in metallurgical works and in the metal-working industry in the fabrication of rings having spring properties.

Title: Vacuum switch contact arrangement
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1984-01-02
Abstract: For exciting an axial magnetic field, the means which are optimum for this purpose are used, namely a simple, flat excitation coil. It consists of parallel-connected winding bodies (4, 5, 7, 8). These windings are connected to a supporting and power-supply body (2) by means of connecting bodies (3) which are parallel to the longitudinal axis. One contact body (44, 55, 77, 88) is fitted on each of the four winding bodies. All the contact bodies are located inside the field space which is surrounded by the excitation coil. This contact and excitation arrangement is attached to both the stationary and to the mobile current-conductor bolts (1). An advantageous solution results when only the stationary current-conductor bolt carries the excitation arrangement. In this case, the number of turns must be increased such that at least approximately the same magnetic field is excited in the switching space as by excitation on both sides. <IMAGE>

Title: Heating wall for coke ovens
Inventor: BLASE MANFRED
IPC: C10B29/02
Filed: 1984-01-14
Abstract: In a heating wall for coke ovens having vertical heating flues which are formed in the region of the lower brick courses within the wall bond from mutually overlapping individual bricks, clamped together by grooves and springs, such as stretchers, bonders and head bricks, it is proposed, to simplify the construction of this heating wall and to reduce its cost, that the upper brick courses, extending above the upper edge of the heating flues up to the oven cover, of the wall bond are also built up by the same bonding system as the lower brick courses located in the region of the heating flues, with interior spaces which extend above the heating flues with the cross-section thereof at least up to just below the oven cover and are filled with filler bricks and/or a refractory mass of a lower thermal conductivity than the coke oven bricks used in the wall bond. The filler bricks used advantageously are relatively smooth moulded bricks having a mutually symmetrical base area and an incision which is vertical in the inserted position and which, together with the corresponding incisions in the further filler bricks, forms an inspection shaft located in the central axis of the heating flue. The filler bricks or filler mass can be made of a relatively inexpensive refractory material, since it is hardly stressed.

Title: Method for determining the frequency of periodically occurring signals, and a device for carrying out the method
IPC: G01R23/02
Filed: 1984-10-24
Abstract: The frequency of periodically, possibly irregularly, occurring signals is determined by measuring the signal period between in each case two signals, determining the deviation of the signal period from the mean value of the previously measured signal periods, updating the mean value using the last-measured signal period (if the deviation is less than a predetermined limit value) and restarting the mean-value formation (if the deviation is greater than the limit value and the number of measured signal periods is less than a minimum number) and determining the frequency from the last-determined mean value of the signal periods (if the deviation is greater than the limit value and the number of measured signal periods is greater than the minimum number). Instead of the signal periods, their reciprocals can also be measured and their mean determined. A device for carrying out the method has a frequency recorder for producing an input signal which is supplied on the one hand to a counter which counts oscillator cycles and on the other hand to a buffer store to which there is connected a read-only memory having a programmed reciprocal function.
