Title: Optical display unit for CRT - has auxiliary films of electro-conducting, electro-luminescent and photo-dielectric materials
Inventor: PRICHODJKO ALEXANDER
IPC: H05B33/22
Filed: 1975-12-09
Abstract: The optical display unit comprises a cathode ray tube (9) with an external display surface (10). Within the CRT is an electrically conducting film (4), upon which are deposited successively on electro-luminescent film (3) a photodielectric film (2) and another electrically conducting film (1). A final layer consists of another electro-luminescent layer (8) facing the electron beam. In use, the electrons cause a luminescence of the display on the internal film which is transferred to the group of films between the conducting films (1,4). These are connected to an external circuit with an A. C source and a switch so that a semi-permanent image equivalent to the original picture may be produced.

Title: Mixer for building materials - having stationary shell with mixing elements rotating in opposite directions
Inventor: HAMMANN HEINZ
IPC: B01F15/00
Filed: 1976-01-28
Abstract: Mixing machine has stationary plate with a circular shaped mixing chamber above it. The plate has an outlet for emptying. The mixer has a pair of mixing baffles moving synchronously and a third element whic can be rotated in the opposite direction. There is a gap between this element and the base plate. The mixing elements can be added to by extra pairs of elements. The synchronised elements cover at least half of the base plate. The drive is by means of a pair of motors with pinions and gear wheels. For use in mixing building materials or other cases of blending solids and liquids e.g. pigment blending. The problems with single set mixing elements are (a) it is difficult to give adequate mixing and discharge satisfactorily with the same elements (b) speeding up the unit may assist but causes some material to be spun over the top of the outlet (c) attrition of the materials and wear of mixer is increased by the increase in speed (d) poor mixing is obtained. The system described overcomes these disadvantages.
Patent DE-2604132-A1 (DE)
Title: Device for wind propelled skiing - has sail on mast held in quiver strapped to skaters lower leg
Inventor: STUMM FRIEDRICH VON
IPC: B62B15/00
Filed: 1976-02-04
Abstract: This device for wind propelled skiing or ice-or roller-skating consists of a sail fitted to a mast (1) whose foot is loosely held in a quiver (4) strapped to the skaters lower leg, close to the ankle. The quiver is sufficiently wide to allow the mast to be manoeuvred by means of the handling bar (2) as required. Should the mast be allowed to fall, the foot will fall free of the quiver without taking the leg with it, thus avoiding any danger to the skater. As this sail is fitted to the leg, thus independent of the skates, this enables the skater to use normal skates allowing one leg to remain free for undependent steering, or manoeuvring.

Title: Material coil holder for drawing machine - has bracket on baseplate with drums having spiral grooves thrusting coils against it
Inventor: TSUKAMOTO KOTARO
IPC: B65H49/26
Filed: 1976-06-23
Abstract: The material coil holder is for wire to be delivered to e.g. a drawing machine. It comprises a bracket (3) mounted on a baseplate (2), and drums (4) to accommodate the coils (A). The surfaces of the drums have spiral grooves (5) of opposite pitch, tending to thrust the coils towards the bracket as the drums rotate. The drums can be of conical shape, tapering towards the bracket, and there can also be grooves (4-1) in their surfaces, running in the lengthwise direction. The design prevents the coils slipping off the drums while being fed to the drawing machine, while avoiding the need for a retainer ring, which has to be removed and refitted each time a new coil is loaded onto them.

Patent DE-2642552-A1 (DE)
Title: Multi-channel underground cable duct - has filler distance pieces giving set spacing between channels
Inventor: BRAMSIEPE ROBERT
IPC: F16L3/22
Filed: 1976-09-22
Abstract: The spacing system is of advantage where multiple circular section cable ducts have to be laid in a trench in the earth. To maintain the distance between the tubular channels (11, 12, 13) and also allow the ducts to be laid in one operation, the gaps (16, 18) between adjacent channels are filled with distance pieces (19). The distance pieces are typically of lattice construction and interlock with each other to form a structure holding the tubular channels together. They also extend over most of the length of the duct section to give support during laying. With this form of spacer the trench size can be kept small. The lattice design allows the back fill to get between the channels, which can assist cooling.

Title: Well injection packer lifting device - with twin power cylinders, claws and backstops and pref. PVC seal rings
Inventor: MAYER FRANZ
IPC: E21B19/10
Filed: 1976-11-27
Abstract: An injection packer is raised in a well from zone to zone by hydraulically controlled claws which grip the packer tubing and move the packer by remote control to the next higher zone when one 33 cm zone has been injected. A backstop mechanism holds the tubing in position while the raising mechanism returns to its initial position. Pref. the packer is fitted with seal rings made of PVC. This saves the manual labour for this operation which requires two men. The precision of the execution does not now depend on the conscientious work of the operators.

Title: Non-return valve for primary coolant duct - has hollow ball as closure to minimise inertia forces
Inventor: LOVINCIC MIROSLAV DIPL ING
IPC: G21C9/00
Filed: 1977-01-17
Abstract: A nuclear reactor pressure vessel has a pressure duct fitted with a non-return valve comprising a movable valve member fitting into the cross-section of the duct. This movable valve member is a hollow object pref. a hollow sphere. Used esp. in the primary coolant duct of a pressurised water reactor. The use of a hollow ball or other object results in a considerable reduction in wt. and therefore in the inertia during the valve closure. The ball may have a thickness-dia ratio of 1/20. With large-dia. ducts up to 750mm, this results in a considerable saving in weight and impact forces on closure of the valve.
Patent DE-2703101-A1 (DE)
Title: Hydromechanical packer for wells - applied by fluid pressure and released by torque and pull (HU 28.1.77)
Inventor: HORVATH ROBERT DIPL ING
IPC: E21B33/128
Filed: 1977-01-24
Abstract: A hydromechanical packet for well consists of an elastic packing which is compressed hydraulically by a piston, locked in the compressed position by a serrated ring on a serrated surface. The packer is released mechanically by first breaking a shear pin on an internal cone for a split nut with an external cone, and by applying a pull on the prodn. tubing on which the packer is suspended. The body of the is surrounded by an auxiliary sleeve on which the elastic packing is arranged. This is compressed and sealed against the casing surrounding the packer by the piston, when the hydraulic or pneumatic pressure exerted on it is big enough to break th shear pin. A lock follows this movement and its teeth engage with the teeth of the serrated surface of the body to keep the packing compressed. This keeps excessive torsional leads away from the prodn. tubing during the release of the packer. The compression does not depend on the load of the tubing.

Title: Electric motor housing MFG - uses cup-shaped housing halves moved together with contacting edges joined and sealed externally
Inventor: SCHWEINFURTER FRIEDRICH
IPC: H02K15/14
Filed: 1977-03-22
Abstract: A housing for an electric motor is liquid-tight and pressure-tight. Two cup or pot-shaped housing halves, open at one side and closed by a floor on the other side, are used. At least one half comprises a cut-out with an edge serving as a hanger, and bent inwards towards the interior of the halves of the housing, and forms the diameter of the housing halves and stator laminations stack by elastic expansion of the halves of the housing. The inner diameter is undersize relative to the external diameter of the unworked stator laminations stack. The wall thickness is sufficient to balance out deviations in manufacturing tolerances. The two housing-halves are moved together until the edges of both halves meet one another approx. in the centre of the stator laminations stack. These edges are joined to one another and to the stator laminations stack, and the joint is sealed externally.
