Title: Securing and positioning empty tubular containers in a shipping carton - with inset having plastics film with prismatic moulded projections
Inventor: ARB EMIL VON
IPC: B65D57/00
Filed: 1977-09-27
Abstract: Packaging inset for stacking and poisoning cylindrical bodies especially empty tubes, in a container, comprises a plastics film band with prismatic projections moulded onto both its sides, the projections extending transversely over its entire width. The zenithal lines of the projections are staggered on one side w.r.t. those on the other side that each zenithal line is at the same height equal to half the distance between two adjacent zenithal lines on the other side. Used e.g. for safe shipping e.g. of empty Al-tubes for subsequent automatic filling. Risk of damaging any printed indicia or pictures on the tubes during transport is minimised. The insets as claimed are inexpensive to mfr. and, being lightweight, do not appreciably increase shipping costs.

Title: Tunnelling machine with two rotart cutters - has cutters on swinging arms for semicircular upper contour and interrupted lower contour
Inventor: OBERSTE-BEULMANN KLAUS DIPL IN
IPC: E21D9/10
Filed: 1977-11-29
Abstract: The tunnelling machine has two rotary cutters mounted at opposite ends of an arm (1) rotating about a central horizontal pivot axis (11), each cutter having its own drive motor. This pivot axis is formed by a member carried by a block (7) which can be raised and lowred between vertical guide surfaces (10) on the machine frame. The top end of the swining arm is connected to a shorter auxiliary arm (12) by a hinge (5) and the other end of the auxiliary arm is connected to another hinge (13) on the vertical centre line of the machine. This enables the lower cutter to make two interrupted cuts at floor level and the upper cutter to make a continuous curved cut at roof level.
Patent DE-2808177-A1 (DE)
Inventor: POPPE ERICH DIPL ING
IPC: E06B9/15
Filed: 1978-02-25
Abstract: The roller-shutter slat (10) is made from a one-piece sheet-metal strip by rolling. On the articulation parts (12, 13), the metal sheet is folded sharply so that the sheet-metal section running out to the fold and the sheet-metal section running back bear against one another in a contour-true manner and the articulation parts are of double-walled design. The end of the sheet-metal section running back is, in the vicinity of the central piece (11), bent off from the sheet-metal section running out and forms a holding web (15, 16) in the vicinity of each of the two articulation parts (12, 13). An additional part in the form of an insertion profile (20) can be fastened to the holding webs (15, 16). The articulation parts are designed in such a manner that the roller shutter slat can be wound up in both directions of rotation. The additional parts can thus be made so large that, when the roller shutter is hanging down, they overlap slightly or abut with one another in order to achieve a good heat insulation without cold bridges. <IMAGE>

Title: Magnetic system for combined train suspension and propulsion - has permanent magnets enclosed by soft magnetic poles to obtain polarity alternations
Inventor: WEH HERBERT PROF DR ING
IPC: H02K41/03
Filed: 1979-06-27
Abstract: The magnetic system has an alternating north-south pole flux distribution. This is provided by permanent magnets arranged in an uninterrupted line of the same polarity, with the polarity alternations provided by soft-magnetic pole blocks directing the flux to the air-gap. The ratio of the pole surface of the permanent magnet to the pole surface of the soft-magnetic poles is selected so that an amplification greater than is obtained for the flux density within the air-gap, relative to the flux density within the respective magnets. An additional variable field is supplied by a winding around each second soft-magnetic pole, the current automatically varied in accordance with the train loading, to maintain a constant air-gap.

Title: Hydraulic servo valve with mechanical return - has emergency hand operation and incorporates multiway main control plunger
Inventor: KUCHARZYK REINHARD ING GRAD
IPC: F15B13/04
Filed: 1979-06-30
Abstract: The multi-way main control plunger or throttling plunger is spring-loaded into the middle position, in which it is held by a pressure, preferably of 10 bar approximately, in secondary actuating chambers at its ends. This pressure is produced by the return springs, supported on the centering spring abutments, and acting on the secondary and primary servo control plungers. Any actuating pressure fluctuation is evened out by nuts acting against adjusting springs. A current in one of the adjusting solenoids acts via the primary and secondary plungers on the return spring, reducing the pressure in the respective actuating chamber, causing the main plunger to move towards this spring. The same effect is obtainable by an emergency hand-operated tappet, the max amount of movement being determined by compression of the return spring.

Title: Building heat recovery method - uses air heated in cavity wall, to supply heat pump
Inventor: WEBER HELMUT
IPC: F24D11/02
Filed: 1979-07-18
Abstract: The heat-recovery method for use in a building operates a low-temp. heating and/or cooling system' particularly where heat-exchange between warm and cold air takes place inside the wall. Air is delivered into a cavity between outer and inner walls extending right round the building, and heated naturally from outside and inside. This air is delivered by pipes to a heat-pump, where the heat is extracted from it again, the air thus cooled being discharged by a fan and air-circulation pipes. It can be returned to the cavity after cooling.

Title: Pulse doppler radar with MTI - has reduced filter frequency relative to pulse sequence to avoid necessity for pulse compression
Inventor: STROBEL HELMUT DIPL ING
IPC: G01S13/526
Filed: 1980-01-25
Abstract: The radar installation has a suppression circuit comprising a delay stage and a subtraction stage, together forming a moving target indicator filter. The filter centre frequency is reduced by a given factor relative to the transmission pulse sequence, by forming the delay stage as a digital or analogue random access, intermediate store with a delay time which is a whole multiple of the period duration of the radar transmitter. The delay time of the intermediate store, and hence the centre frequency of the filter, is pref. variable. The centre frequency of the filter can be held constant independent of a variation in the pulse sequence frequency. The radar does not require a pulse compression circuit, thus allowing its size to be reduced.
