Title: Variable plan multiple purpose prefabricated building elements - comprise external wall elements, internal columns and concrete ceiling and floor slabs covering defined spaces
Inventor: SOLTAN STANISLAW PERESWIET
IPC: E04B1/04
Filed: 1976-04-26
Abstract: The building system makes use of prefabricated elements permitting a variable plan, for swellings, schools, hospitals etc. The three groups of elements comprise load bearing external wall elements (X), interior support columns, (Y) and floor-ceiling slabs (Z) to cover the spaces defined. Construction begins with a reinforced concrete base slab set on the foundations. The external walls and columns are then erected on this, according to the requirements of the plan, and the prefabricated reinforced-concrete floor-ceiling slabs are positioned, supported partly on walls and partly on columns. Flooring, doors and windows, and other internal fittings, are subsequently added in the normal way. The three groups of elements can be interconnected by reinforced-concrete links, cast into open spaces at the points of contact.

Title: Safety belt reel arresting mechanism - has locking element arranged asymmetrically to tilting axis and accommodated within recess of take up spool
Inventor: HJELTE SVEN ROLAND
IPC: B60R22/38
Filed: 1976-05-31
Abstract: A spool core is under the stresses of a spring in the take-up direction, with an arresting element at one and following the rotary movement of the core. During sudden uncoiling movement of the belt, the arresting lelments engages in an internal serrated surface provided on the frame of the take-up mechanism. The arresting element is asymmetrical to its tilting axis. The stationary it stays within a recess on the circumference of the spool core. A carrier element under normal conditions follows the rotary movement of the spool core, but if forced to rotate at a different speed from that of the core actuates a ratchet-type arresting mechanism, which then stops further rotation of the spool.

Title: IC engine electronic fuel injector system - has circuit to prevent slow running fluctuations
Inventor: KRAUS BERND DIPL ING
IPC: F02D41/14
Filed: 1976-06-11
Abstract: The exhaust collector pipe contains an oxygen sensor (10) to emit signals corresponding to the fuel air mixture composition. The signals are compared with a threshold value voltage. A time switch compares an adjusted dead time with an ascertained engine dead time to control a regulator circuit in such a way that on the appearance of strong fluctuations, greater time constants can be selected by switching extra resistances into the resistor system. The circuit consists of a comparator stage (1) a time circuit (2), a regulator circuit (3), and a final regulator stage (4) controlled by the regulator circuit. The comparator output triggers a a mono stable trip switch (2) whose dead time corresponds to the engine dead time. The mono-stable trip switch consists of a transistor whose emitter is connected directly to earth and collector to positive potential via a resistance (R6).

Title: High-pressure cleaning appts. with chemical action - has chemical suction switched on without interruption of work process
Inventor: SCHULZE WERNER ING GRAD
IPC: B08B3/02
Filed: 1977-10-13
Abstract: The reversal mechanism which closes the by-pass pipe (22) enclosing the chemical suction pipe and opens the return pipe branching off in front of the latter, comprises a displaceable piston (15).

Title: Assembling lengths of PVC-film-lined concrete drainage pipes - which are fitted with elastic axially compressible receiving rings and annular seals
IPC: F16L21/035
Filed: 1978-02-04
Abstract: Concrete pipe for conveying effluents is lined with plastics e.g. PVC film is connected to a similar, adjacent pipe by means of coaxial extensions at both ends at each of which there is an annular body surrounding the inner wall and forming a sealing surface. These bodies are made of entropy-elastic material and are fastened to the lining. The annular bodies, one being a centring ring and the other a take-up ring, are differently shaped so that when the pipes are fitted together, the take-up ring of any one pipe length engages the sealing surface of the centring ring of the adjacent pipe. The centring ring then surrounds the extension of the lining and can be compressed axially to ensure reliable seal and positioning.
