Title: Transparent constructional elements, pref. made of glass sheet - bent along both longitudinal edges to form a profiled section
Inventor: LOEBL ERICH
IPC: C03C27/12
Filed: 1974-02-19
Abstract: A sheet- or strip constructional element with upturned edges which is permeable to light, pref. made of glass, has a shape such that several of these elements can be put together to form an assembly or sub-assembly of surfaces which permit the transmission of light. The two longitudinal edges are bent up to form sections of unequal height where the height of the tall edge (h), the height of the short edge (n) and the thickenss (d) of the glass sheet have a fixed relationship so that h+d=2n+a, where (a) is between 1/20th and 2.5 times (d), and the width (b) of the flat part of the glass is min. 1.k x h; the angle of the bends is chosen between 15-165 degrees. The glass may be treated so it is light-dispersing, coloured, reflecting, partly transmitting, electrically conducting, reinforced or quenched. The assembly may be used as a glass wall or roof in all types of buildings.

Title: Spring steel wire bracket on ski boot fixture - acts as brake for loose ski
Inventor: RIEDEL TILO
IPC: A63C7/10
Filed: 1974-03-15
Abstract: A spring wire bracket is attached to the ski boot fixture in such a way that it acts as brake for a loose ski. When the brake is not in action, the root of the bracket is pressed onto the ski by the heel of the boot. This causes the two forward pointing prongs of the bracket to be orientated along the two top edges of the ski. The slotted fixture heel plate locates the bracket at about mid point of the prongs. A spreader plate with inclined sides produces a bending moment in the bracket which tends to rotate it into the operating position when it is released. In this way it is possible to overcome the problem of iced up brake brackets.

Title: Acoustic bird-scarer for gardens - has electric motor or spring driven timing cam and includes metal foil sound emitting member
Inventor: THOMA HORST
IPC: A01M29/16
Filed: 1974-04-23
Abstract: The drive motor drives a timing cam fixed to a spindle by means of a reduction gear consisting of a small toothed wheel mounted on the motor axle, and a toothed-wheel connected to it. When the timing-cam reaches the highest point underneath the plate spring fixed by its bent end to the partition wall of a housing, the plate spring is impelled downwards after it has gradually been raised by the step-pulley. A strip of aluminium foil, used to produce a noise is fixed to the eyelet at the free end of the spring. A variable resistor incorporated in the circuit can be altered as desired to vary the intervals at which sound is produced the circuit also including a time switch.

Title: Continuous microwave oven - has rotor whose conducting vertical shaft carries a conducting horizontal disk
Inventor: KIRPICHNIKOW WLADIMIR PAWLOWIT
IPC: H05B6/78
Filed: 1974-06-18
Abstract: The oven has a charge-discharge part, a rotor with supports for the heated goods, and a microwave generator. The above disc is limited by an annular channel, and is divided by vertical radial partitions in compartments, in which the heated goods stand on dielectric supports.

Title: Transformer and switching indoor or outdoor substation - is fitted with switchgear on two floors at 90 to each other in cruciform shape
Inventor: GEITEL KURT ING GRAD
IPC: H02B5/00
Filed: 1974-11-02
Abstract: By arranging the switchgear in the form of a cross, but on two levels, desirable space savings can result. Typically the floors are confined to one voltage each, and each can then be laid out without reference to the other, thus no unused or wasted space results. For example the HV switchgear (2) may form the upper floor which crosses the LV gear (5) in the lower floor at 90 deg., each being contained in its own housings. The transformers (7) may be located within the area of the rectangle containing the crossed housings, or they may be installed under the overhanging sections of the upper floor. Measuring and telemetry equipment may be similarly disposed.

Title: Pneumatically stretched plastic foil window - uses two gas tight sealed sheets with gas or air introduced through valve
Inventor: SCHOELL GUENTER PROF DR ING
IPC: E06B7/28
Filed: 1975-01-28
Abstract: The window contains pneumatically stretched transparent plastic foil sheeting. Two foil sheets (2), laid one on top of the other, are joined together with a gas-tight seal at their peripheral edge, by welding (3). After their fixture in a flat state on a window frame, a filling of air or gas, at a pressure exceeding outdoor atmospheric pressure, is introduced by a valve (6) which opens out into one of the sheets. When a double-sheeted window of this type is heated or cooled, the air or gas filling between the sheets undergoes a spatial expansion or contraction, to compensate for the surface expansion or contraction of the foil sheeting, which exceeds that or normal silicate glass.

Title: Sheet strip alignment control system - has folding triangle swung about transverse axis by drive to correct alignment
IPC: B65H45/22

Abstract: The system regulates the feed of a strip of sheet material as it is folded along a line parallel to the direction of feed e.g. when producing bags, having a holding triangle holding the strip under constant tension normal to the direction of feed, while an adjusting mechanism is controlled by a strip edge position detector. The triangle swings on an axis normal to the direction of feed of the strip, the drive to the triangle forming the mechanism determining the strip edge position. The difference between the desired position and the actual one as indicated by the detectors causes tilting of the triangle to correct alignment.

Title: Tubular cables jointing using niobium and copper conductors - has tapered ends forming funnel and cone with tin layer at interface
Inventor: MUESEBECK HORST
IPC: B23K1/002
Filed: 1975-06-09
Abstract: The conductors are components of a super conducting cable. The ends of the conductors to be joined are tapered so that one end fits into the other. One of the conductors will form a funnel and the other a fitting cone. A layer of tin is applied between the two surfaces at the joints and a superconductive intermetallic junction of niobium and tin is produced. This is done by heating to a temp. below that of the m.p. of the copper. The high temp. is maintained for between 10 and 50 minutes. The tapering of the walls of the conducting tubes is approximately 1 to 10. They are held in position by spring pressure during the heating process.
