Title: Fluid cooled nuclear reactor - with negative temp coefft of reactivity
Inventor: GEORGE BRIAN VICTOR
IPC: G21C1/32
Filed: 1972-05-18
Abstract: The mass flow of gas coolant through esp. advanced gas-cooled reactor is throttled to produce rapid drop in thermal output power from the core into the heat exchanger (boiler) section; this raises the core temp. to a point at which the reactivity is lowered but not to such a level that the safety rapid shut-down system is activated. Approx. simultaneously with the throtting, control rods are introduced into the core to assist the redn. in reactivity.

Patent DE-2365645-A1 (DE)
Title: Fabricating thermoplastic layflat film - in two layers oriented at right angles
Inventor: SUDO MICHIO
IPC: B29C48/11
Filed: 1973-02-24
Abstract: In a process for fabricating a laminated cylindrical film with a plastic resin base, the laminated structure consists of three layers, the inner layer being stretch oriented transversely and the outer layer being stretch oriented longitudinally. The median layer is formed from a film having a lower fusion point than the inner and outer layers, and consolidation is brought about by heating to a temp. slightly below the fusion point of the median layer so that it is bonded to the other two layers. The three layers may be extruded from annular concentric orifices, and orientation in perpendicular directions gives greater strength and enables thinner films to be used for a given weight. The three films are extruded from concentric orifices. The outer layer is then stretched longitudinally between two sets of rolls while the inner film is expanded by a rotating mandrel, the film being then cooled rapidly and flattened. The outer and inner layers may be of a high m.pt. polyolefin while the median film may be of e.g. ethylene/vinyl acetate or ethylene/acrylonitrile copolymers.

Title: Clamp for large calibre gun sealing rings - has helical gears for actuating clamping nuts of sealing rings
Inventor: SACKENREUTER HANS DIPL ING
IPC: F41A9/45
Filed: 1974-03-13
Abstract: The sealing clamp system is used to seal the shell chamber of a large calibre gun, such as a launcher, in which it is necessary to seal the shell chamber ends effectively. The clamping mechanism presses the sealing rings simultaneously in the opposite direction against the barrel and the breech. The drive shaft actuates helical gears with opposite helical teeth which engage those of nuts on the ends of the shell chamber. These nuts impart axial movement to the sealing rings. The actuating shaft is operated by a handle and is held in bearings so that the shaft can float axially. The shell chamber is pivoted at its middle out of the breech frame of the launcher for loading, and the seals are pulled back for this purpose.

Title: Connection for relatively movable pipes - has central vee connector releasable at preset tensile load and anular channels to retain fluid
Inventor: SKIBOWSKI HUBERT
IPC: F16K3/26
Filed: 1974-05-24
Abstract: Pipes such as (10) are bolted to either end of a connector which is made in two parts (15) secured together by a cylindrical vee clamp (21) which is designed to release connector parts under a predetermined tensile load. A central body in the connector forces the flowing medium to flow around its periphery through a cylindrical passage closable by cylindrical piston, should the connection fail, in order to prevent loss of fluid. The pistons are caused to move to close the pipes by means of pneumatic control pressure applied through ports by an external pressure source. The connection is partic. for use with oil tanker filling systems.

Title: Rock drill hammer advancer - pivoter has two consecutively acting cylinders, each with right angle pivot range
Inventor: LEPPAELAE MATTI
IPC: E21B7/02
Filed: 1974-08-29
Abstract: A pivoter for the advancer of a rock drill relative to the drill arm about a transverse horizontal axis has two consecutively-acting working cylinders. The first pivots a lever and also the axis in a 90 deg. range, and the second cylinder attached to this lever pivots the axis relative to this lever through a range of 90 deg. The drill arm is attached to the drill carriage such that it is pivotable by the pressure cylinders in the horizontal and vertical direction. A weight of the drill hammer advancer is connected to the upper end of the arm such that the weight, and hence also the hammer, are pivoted by the cylinder. The drill rod can thus be quickly aligned in a given direction.

Title: Control unit for printer type carrier adjustment - has two operating arms associated with circular control sleeve on the input and output shafts
Inventor: HANENKAMP HORST
IPC: B41J7/56
Filed: 1974-10-03
Abstract: The two operating arms (14, 15) can be individually controlled by an operating element (24) which has projections (22, 23) displaced relative to one another in a direction which corresponds to the direction of movement in which the actuating element can be adjusted for two different positions i.e. the 'O' or 'L' positions. The actuator movement is accomplished e.g. transverse to the axial direction of a support bolt (19) which carries the swivelably arranged operating arms (14, 15). With this design, binary control is accomplished using the minimum number of functional parts thereby simplifying construction and facilitating a higher speed of operation of the printer.

Title: Insulating board of granulated waste and synthetic binder - is continuously produced by double belt press fed from moving mixing channel
Inventor: ARMBRUSTER FRITZ DIPL ING
IPC: B29B17/00
Filed: 1974-10-03
Abstract: Insulating and facing plates or boards consisting of granulated plastics and rubber waste and setting resins as binding agent are produced as endless bands of sheet material of maxim uniformity in construction, the binding agent being concentrated in the voids between the granulated and the granulate not being compressed so that it does not expand later; the whole process comprises a continuous flow of material from the feed of raw materials to the discharge of the finished band. The process is continuous, by comparison with intermittent conventional processes. This leads to improved economy and higher quality in the finished prodt.

Title: One piece cable or cord grip - is used for retaining cable or cord passing through aperture in wall
IPC: H05K7/00
Filed: 1974-11-19
Abstract: One piece cable or cord grip with means of grip release has means, independent of its cable release function, to maintain it locked in an opening. A hinged toothed clamp is used when pressed downwards towards the cable passing through the grip it locks with teeth in the part of the grip surrounding the opening, at the same time exerting clamping pressure on the cable or cord through a surrounding sleeve. This sleeve is used to prevent abrasion and is part of the one piece cable grip. The one piece grip can be made in one moulding operation, and has no screws or metal parts.

The shaft (8) driving the tool is in a fixed position in relation to the capstan (1) carrying the tools, and the main spindle (3) and workpiece are adjustable at right angles to this shaft and to the capstan axis. When the drive shaft is coupled to the shaft (9) on the capstan, the locking mechanism preventing tool rotation can be automatically released, this being engaged again on uncoupling. The tool can be steplessly adjustable in relation to the capstan shaft (9).
Patent DE-2512588-A1 (DE)
Title: Roller-type pinch cock - for controlling liq. flow through a pliable tube
Inventor: WATANABE MASAHARU
IPC: A61M39/28
Filed: 1975-03-21
Abstract: Roller-type pinch cock, to control the amt. of liq. delivered through a plastic tube of a given thickness, consists of a box with lateral walls and a base. Supporting grooves in the walls receive and guide the bearings of the roller which can be moved along the box by hand. The upper surface of the base is rounded in section, to receive the pliable tube, and is inclined w.r.t. the side walls. The roller has a knurled surface and as its is moved along the box it compresses the tube against the base and so controls the amt. of liq. passing through the tube. The amt. of liq. passing through the pinch cock can be controlled rapidly to the desired value; and subsequent variation is only very slight. The tube can be compressed practically without any channelling.
