Patent DE-1921666-A1 (DE)
Title: Redn of stress peaks at support points of - nuclear reactor enclosures
Inventor: FRIEDRICH JOCHUM DIPL-ING
IPC: G21C13/087
Filed: 1969-04-28
Abstract: Redn. of stress peaks at support points of nuclear reactor enclosures Where the axially symmetrical pressure tank emerges from the supporting, concrete (or other material) shell, an annular recess is provided, open towards the tank, partly filled with water or other fluid. The head of fluid builds up a linear counter-pressure that increases with depth, thus reducing excess pressure inside. Mercury, sealed off to safeguard against toxicity, may be used because of its high specific gravity. Temp. effects are also minimised by cooling achieved round the moistened area, reducing the stress peaks at the point of support.

Title: Pressure-differential vacuum casting process - maintaining deeper vacuum outside than inside porous mould during pouring
Inventor: FROER WERNER
IPC: B22D18/06
Filed: 1972-10-18
Abstract: Metal castings are produced by melting the metal in a vacuum and by pouring the metal into the preheated mould which is also kept at a vacuum. When pouring starts, the outside of the proous mould is kept at a deeper vacuum so that the press. difference keeps the metal close to internal surfaces. The inside press. is then raised to atmospheric or more while the outside vacuum is maintained until the metal has solidified.

Title: Music transposition from key to key - by shifting transparent sheet over lined base sheet
Inventor: GRASSL FRANZ
IPC: G10G1/04
Filed: 1973-06-13
Abstract: Music can be transposed from one key to another without the high skill and long time required at present to do it manually. A base sheet contains a number of parallel lines, each octave represented by seven lines, where the distance from each line to the centre of the space between the lines corresponds to one semitone. A transparent sheet on which the music is writted is now placed over the base sheet and moved up or down to the desired transposed state, where a photostat copy can be made. No sharps or flats are needed in this system but the piano keyboard should consist of a regular succession of short keys and long keys.

Title: Two-roll bar straightening machine - in hinged housing giving easy accessibility for rapid regrinding in situ
Inventor: LINDEMANN HANS HANS
IPC: B21D3/04
Filed: 1973-07-12
Abstract: A straightening machine with two rolls on horizontal axes, which can be adjusted for height and gap, is mounted in a housing. The upper part of which can be swung open on a horizontal axis which is parallel to, and at one side of the roll-axes. The pivot-axis pref. lies on a horizontal plane between the two roll-axes and outside the housing. Due to this construction, the rolls are rapidly accessible and can be re-ground while still in the machine. As the accuracy of the straightening or setting of the bars, passing through the machine depends on the condition of the roll surface, frequent re-grinding is essential.

Title: Monitor cct. for correct functioning of mercury switch contacts - uses logic supplied from two triggers coupled to switch two opposing contacts
Inventor: LECHNER ROBERT ING
IPC: H02H7/22
Filed: 1973-07-26
Abstract: The monitoring circuit consists of two amplifiers, one coupled to the mercury switch activating contact and the second one to the switch rest contact. the common switching contact is coupled to a negative potential. The activating contact is also coupled to the switch load, e.g. a relay. The outputs from both amplifiers are passed to two separate triggers which generate outputs when given levels are exceeded. The two triggers feed a logic circuit whose third input receives a signal when the mercury switch is operated. If the switch fails to operate, the logic receives a signal from one trigger which should, if the switch had switched over correctly, have come from the second trigger. If the switch fails completely by having both its contacts 'live', the logic reacts by switching out the load, or in the case of relay, by preventing it from operating.
Patent DE-2339897-A1 (DE)
Title: Accurate fluid flow measurement - using propeller mounted in specially shaped plastics housing involves partially radial and axial flow
IPC: G01F15/14
Filed: 1973-08-07
Abstract: A system is presented for the accurate measurement of fluid flow using a simple propeller system mounted in a suitable housing. The propeller axis is mounted along the line of flow, but away from the centre line of the conducting pipe. The flow impinges on one side of the propeller and is deflectied along a somewhat complex path to be ejected nearer to the line of the propeller axis. This arrangement implies that the propeller housing projects on one side of the flow path. The housing may be made of plastics and the inside has a carefully shaped contour. A filter is also included in the arrangement at the entry to the propeller housing.

Title: Microprogramme memory controlling path control switch sets - is used to control data-processing system or telephone exchange
Inventor: FUCHS PETER DIPL-ING
IPC: G06F9/22
Filed: 1973-08-27
Abstract: Micro-commands are stored in memory positions in the form of uncoded path control signals, in order to transmit the micro-commands, forming a micro-command batch and to be read simultaneously, to the path control switch sets, directly, by way of decoder-free control lines, in the form of corresponding path control signals, simultaneously during a machine cycle. At least a part of the memory positions not required to control the path control switch sets is neglected. Only part of the micro-commands are stored in the form of uncoded path control signals, the rest being stored as coded signals.

Title: Spacer clamp joining steel mesh and lattice girder - with bar-accommodating jaw wedge-tapering and maintaining constant interval
Inventor: KELLER JULIUS GEORG STEFAN DIP
IPC: E04C5/16
Filed: 1973-09-17
Abstract: The clamp's function is to connect a structural steel mesh to a lattice girder and at the same time establish the distance of the reinforcement from a formwork surface. Accommodation of the bar of the steel mesh is in the jaw which can bbe inserted into it along the line of the girder's lower chord. The open ei dth of this narrows in a wedge shape from the jaw opening, for self-locking, with the bottom boundary surface of the jaw engaging below the bar, and a constant interval maintained from the clamp's edge surface, and with the top boundary providing the support surface for bracing against the top of the girder's lower chord. The jaw pref. runs in a downwards convex arch along the line of the bar. This is a single-piece unit, easily fitted and adaptable to bars and chords of different thicknesses.

Title: Release clutch for actuating drive of awnings and roller shutters - has cylinder with axially projecting fingers and engaging radially toothed components
Inventor: GEIGER GERHARD
IPC: E06B9/68
Filed: 1973-09-21
Abstract: The mechanism has a roller fitting in the bore for the shaft and this roller has coupling fingers which project in the axial direction. Coupling elements are arranged between the clutch fingers and a disc component. On the shaft of the awning rotates a carrier which has radially projecting teeth. This clutch member has a cylindrical body whose bore diameter accommodates the outside diameter of the roller. The axial length of this clutch member is equal to the axial length of the fingers. The outside coupling teeth of this ring are equal in number to the clutch fingers and these teeth are chamfered on both edges. This clutch element can be moved axially and its teeth engage with the gaps between the clutch fingers. When the shutter is lowered then the fingers are only in engagement with the sloping faces on the outside teeth. The clutch is disengaged when the shutter comes to its end position.

Title: Pneumatic nail gun for nails or staples mounted on a strip - has recoil force which aids driving in the nails
Inventor: RENFTLE ALBERT
IPC: B27F7/09
Filed: 1973-11-03
Abstract: The nail gun consists of a housing in which a pneumatic piston with ram moves to and fro. A strip of nails or staples is fed sideways into the housing. The housing is supported vertically in such a way that the recoil force of the ram on the rail is directed against the nail being driven in. The recoil time of the support system is so chosen that the recoil force of the housing of the nail gun supports the piston. The vertical housing can be supported on the piston of a hydraulic cylinder to achieve this. The liquid supply to the cylinder will then be provided with a non-return valve.
