Title: Rocket missile extending stabilising fins - have sections extended progressively by springs and releasing charges
Inventor: KNOCHE HANS-GEORG DR RER NAT
IPC: F42B10/16
Filed: 1976-10-29
Abstract: The rocket propelled missile has stabilising fins extended in starting phase step by step. These fins are extended to match the stabilising requirements on launching. The fins are extended according to a specific programme. The fins are held so that they or their actuators do not project beyond the missile circumference. The stabilising fin sections (1, 2, 3) are extended in stages until the whole articulated fin is extended. Each fin section pivoting axis is parallel to missile longitudinal axis. These axes are spring (17) loaded. A folded fin section is released by pyrotechnical delay element which initiates releasing charge of locking bars (25).

Title: Draining gulley for industrial use - has two inlets to drain floor and plant with separate smell traps and dirt collectors
Inventor: WIEDEMANN CLAUS
IPC: E03F5/04
Filed: 1977-01-05

Title: High speed mosaic printer - has wire movement aided by fluidic ferrite material and applied magnetic field
Inventor: GRIMM ARNOLD
IPC: B41J2/235
Filed: 1977-01-07
Abstract: The high speed mosaic printer is for input to and output from a data-processing machine. It has printing wires located movably in boreholes which are guided through ceramic parts and a bismuth alloy. The intermediary space in the printing head formed by the ceramic part, the bismuth alloy and the aluminium body which holds them is saturated with a 'fluidic' material which is enriched with ferrite having a diameter in the nanometer range. So long as the ferrite is not subjected to a magnetic field, the normal viscosity of the carrier fluid is unchanged. Application of a magnetic field, however, acts on the ferrite, increases the sliding ability of the needles and aligns them in their boreholes.
Patent DE-2701380-A1 (DE)
Inventor: KLYSZ EDWIN
IPC: E21D11/40
Filed: 1977-01-14
Abstract: The support unit, independent of the driving unit and designed as a trailer (10), is a lattice girder which is supported on rails via travelling gears (8, 9) and has a head (11) with a slewing ring (12) of a slewing-ring erector. In its rear part, the trailer (10) has a tubbing intermediate store (14) for the tubbing (24). Fastened above the trailer (10) is a crab running rail (25) which extends to the rear over a tubbing haulage truck (4) and at the front end through the slewing ring (12) and projects beyond the latter by at least a tubbing width, the tubbing (24) being moved along the running rail (25) by two crabs (28). Simple feeding and transfer of the tubbing (24), which does not impair the erector operation, to the slewing-ring erector is obtained with this apparatus. The trailer (10) can be displaced by a piston/cylinder unit (32) and clamping jaws (33), lockable on the rails, and can be secured in its position by clamping brakes (34). <IMAGE>
Patent DE-2710518-A1 (DE)
IPC: B65B9/06
Filed: 1977-03-10
Abstract: A conveying member (12) is arranged on a stand and delivers a pack (1) to a foil-dispensing station (3a). The conveying member (12) has sliding units (14) formed on a chain (13). A transparent foil (3) is wound up to form a foil roll (3a). A roller (81) is followed by a conveying member consisting of a heat-resistant thin belt. A weighting-roller arrangement is provided on the top side of the conveying member, in order to increase the adhesion between the upper surface of the pack and the upper surface of the conveyor belt. There is, furthermore, a drawing mechanism (40) which clamps the foil (3) between belts (41). The foil parts running between the individual packs (1) are severed by cutting motors (56, 57). A vacuum pump (68) connected to the housing ensures that the foil ends (3b, 3c) are wrapped round onto the lower surface of the pack. The foil ends are welded together by means of a heating conveyor member. The length of the foil can thus be adjusted freely according to the length of the pack, so that packs of varying size can be processed. <IMAGE>

Title: Drawing die grinding and polishing machine - has slow reciprocation applied at right angles to vertically oscillated work holder rod
Inventor: PETER HANS
IPC: B24B35/00
Filed: 1977-05-24
Abstract: The grinding and polishing mach. has a vertical work holder rod (2) reciprocated vertically by a motor driven eccentric (13) at the top. An adjustable work support arrangement (4) below carries the work. At a point above the work support, is a bush (15) driven by a belt drive (16) from a motor (18) with its output shaft vertical. Attached to the bush is a horizontal piston (20) with a spring (21) around it, inside a sleeve (19). The end of the piston passes through the bush so as to exert a force against the work holder (2) at right angles to its reciprocation. This oscillates at a lower frequency than the vertical reciprocation. Opposite the piston, an adjusting screw (22) passes through the bush.

Title: Coupled photochemical synthesis of hydrazine and hydrogen peroxide - by reacting nitrogen and water with sodium and sodium peroxide formed photochemically
Inventor: RADEBOLD REINHART DR
IPC: C01B15/043
Filed: 1977-09-16
Abstract: Synthetis is effected by (a) converting Na2O, dissolved in molten NaOH, to Na and Na2O2 by a photochemical reaction; (b) reacting the Na in part directly with the NaOH, forming H2 and Na2O, and in part with the H2 formed and with N2, forming NaNH2; (c) oxiding the NaNH2 with part of the Na2O2, forming N2H4 and Na2O, and hydrolysing part of the Na2O2 with H2O forming H2O2 and NaOH; and (d) recycling the soln. of Na2O in NaOH formed to stage (a). The process allows solar energy to be stored in the form of metastable chemical cpds., which can be used directly as fuels. They can be stored and transported easily as liquids (stabilised by mixing with water), can be used in normal technical systems without major modification and do not upset the ecological balance.

IPC: A61B5/024
Filed: 1977-12-24
Abstract: The heart pacemaker has a heart beat measuring system with an instrument worn on the wrist like a wrist watch, with electrodes insulated from one another. Three ring shaped electrodes may be used to obtain signals which are amplified, filtered, differentiated then digitally processed. When a signal which exceeds a given safe value an alarm is sounded. The value of this signal can be adjusted. Signals which can be obtained from the period or frequency of the heart beats or the pulse width of the pacemaker signals can be used to give a visual display. The momentary pulse width can be measured. The alarm device which emits a stimulating signal is located underneath the housing of the measuring instrument.

Title: Tunnel lining for soft earth - consists of quasi-rectangular steel sections welded together to form zigzag outline
Inventor: RAWERT HEINRICH DIPL ING
IPC: E21D11/14
Filed: 1978-01-04
Abstract: The tunnel lining system uses steel sections (71, 74) attached to each other along the tunnel which may be formed in soft wet sand which requires freezing to prevent it caving in during construction. Each section is quasi rectangular in shape, with each side of the rectangle made from a sloping curved sheet. Thus, when a series of sections is assembled, the line of sheets forming a side of the tunnel forms a zig-zag shape. A space can be left between the lining and the sand which is filled with a substance which can include a plastics material. The sections can be welded together.
