Title: Reactor vault of reinforced concrete has ring of blocks - surrounding vessel to form thermal shield containing ion chambers
Inventor: SCHOLDAK GEORGY IVANOVITSCH
IPC: G21C13/08
Filed: 1979-06-22
Abstract: A nuclear reactor vault, comprising a reinforced concrete shield wall surrounding the reactor vessel and containing ionisation chambers, is constructed as follows. An internal protective or thermal shield is composed of a series of prefabricated reinforced concrete blocks; these are arranged to form a continuous cylinder or ring around the reactor vessel, except for radial gaps between the blocks to permit expansion and movement. The ring of blocks is supported on a ledge in the surrounding reinforced concrete shield wall, the blocks thus being arranged in a continuous recess above the shoulder of the wall and below an overhang or corbel. The blocks are pref. of heat-resistant concrete. The protective shield is remote from the wall of the reactor, thus improving conditions in the event of an earthquake. Access inside the shield wall for direct inspection of the vessel wall is possible. Prefabrication reduces construction time by 60-80 days.
Patent DE-2928111-A1 (DE)
Title: Two=stage baling press - with stationary press box having two presses mutually at right angles
IPC: B30B9/30
Filed: 1979-07-12
Abstract: A two-stage baling press for textile fibres has a preliminary press and a main press oriented at right angles to each other which compress the fibre successively in two directions without the need to re-orient the half-formed bale or manipulate it in any way. The press box is charged from above with a weighed amount of fibre. The preliminary press plate forms one complete wall of the press box and compresses the fibre horizontally to the required width. The main press is above the box, and compresses the fibre vertically to the final bale size. The press is simpler to construct and operate than previous designs. It is cheaper, and works more rapidly, since the press box does not move.

Title: Oil control valve for diaphragm compressor - has spring-loaded piston lifted from seat by gas pressure to release oil
Inventor: STRASSBURGER FRIEDHELM
IPC: F04B43/00
Filed: 1979-09-15
Abstract: The oil control valve consists of a seat (2) retained in a housing (1) by a pressure coupling (4). The valve plug (3) is held against its seat by the piston (5), which is loaded by a spring (6).

Title: Electronic music PAM control circuit - has VCO driven by mixed DC-VLF signal to clock stored analogue values through bucket-type shift register stages
IPC: G10H1/043
Filed: 1979-11-21
Abstract: The circuit uses bucket type shift register (6) whose individual stages store analogue values applied at a terminal (6-5) which are passed on from stage to stage by application of two clock phases at terminals (6-4,6-1). The clock pulse generator (12) is a voltage controlled oscillator responsive to a mixed d.c. and variable very low frequency voltage applied to the phase control input (12-5). Two different phase control input voltages (13,14) may be applied to two channels. The shift register clock frequency may vary between 30 to 110KhZ and the delays produced thereby cover an adequate phase range. The output from the analogue shift registers (5,6) is combined at the common output (23), amplified to loudspeakers. The phase change rhythm for one channel may for example be 1-2 Hz, whereas the rhythm for the other channel may be 7-10 Hz. A third channel may be provided which contains slowly changing d.c. level changes to control the average phase delay, or the changes may be applied to the channels on an individual basis.

Title: Securing catch for tilting rear seat - has double jaw with retaining tag in inhibit closing until over locking stub
Inventor: ENSSLEN ARNOLD ING GRAD
IPC: B60N2/36
Filed: 1979-12-14
Abstract: The securing catch is for a folding rear seat. The seat back is held on each side of the car by double jawed catches (3,6) which grip bolts (5). The jaws are designed to assume an open position, held by a striker plate (11b) until the bolt fits securely in the jaws. This prevents premature closing of the jaws with a subsequent unsafe support for any seat belts. One jaw lever is U-shaped (10) and tilts when struck by the bolt. The other jaw lever (3) is mounted on a crossbar (12) for simultaneous operation of both catches and has the striker plate (11b).

Patent DE-3008417-A1 (DE)
Title: Refining steel in basic oxygen furnace - using final argon blow to achieve low carbon content
Inventor: CRESWICK WILLIAM ERIC
IPC: C21C5/32
Filed: 1980-03-05
Abstract: In the mfr. of steel, esp. low carbon steel, in a basic oxygen furnace, oxygen is blown through a lance onto the metal bath until the carbon content of the bath is about 0.10% above the desired final value, and the oxygen blow is then replaced by an argon blow until the desired carbon content is achieved. The argon stream agitates the bath and causes the dissolved oxygen to complete the refining process, and thus a cleaner steel product is obtd. Compared with baths in which oxygen is used all the time, the amount of iron oxide is reduced and the slag is more viscous and easier to separate. This in turn gives more efficient deoxidation (e.g. using Al) and reduces the amt. of corrosion of the furnace lining.

Title: Prestressed concrete component prodn. system - uses wax to seal joints between mould sections and for reinforcing components retaining recesses
Inventor: KLEMM HANSJUERGEN PROF DR
IPC: B28B7/00
Filed: 1980-10-09
Abstract: The prestressed concrete components are produced by passing the reinforcing components through openings in the ends of the multi-section mould for engagement with the stressing mechanism. The mould is then covered by a cowl containing a filler opening and the concrete is compacted by vibration, after pouring. The protruding reinforcing components are cut to length after concrete setting and the mould is then knocked down. Wax is used to seal the joints between the sections of the mould and also those between the reinforcing components and the mould openings. It can be poured into the joints in liq. state and there hardened by a change in temp. The wax is melted again after concrete setting, so as to run out of the joints automatically.
