Title: Pressure reducing valve for steam, gas or liquid - permits regulation without high noise level and valve damage
IPC: F16K47/08
Filed: 1975-04-05
Abstract: The fluid enters a lower chamber and passes through non-restricting holes into the interior of a cylinder (2), and then upwards through a valve port into another cylinder (7) in which a piston (4) is moved to adjust the flow. This cylinder also has radial holes drilled in helix formation which lead to restricting passages in an outer cage (8). This consists of a stack of rings forming alternate expansion chambers and throttle openings in a helical arrangement in line with the holes in the cylinder. A radial series of such expansion chambers and throttles may have the addition of any desired number of concentric rings, all with chamber separating plates, fitting one outside the other. The complete assembly is then clamped with top and bottom blanking plates. From here, the fluid passes into the low pressure pipe.

Title: Uranium dioxide pellets in zircalloy fuel can - with nickel particles to form protective film on can wall
Inventor: MAKI HIDEO
IPC: G21C3/17
Filed: 1975-09-10
Abstract: A nuclear fuel element is constituted of a no. of fuel pellets inside a sealed can. Nickel or a nickel alloy is incorporated in between adjacent fuel pellets, esp. in a zone where the temp. reaches the fusion point of the nickel or alloy during reactor operation. The design is used in partic. for UO2 fuel pellets inside a zircalloy-2 can. The operating temp. causes nickel vapour to be produced inside the can; this deposits upon the inner face of the can forming a nickel film which absorbs iodine produced as a fission prod. from the uranium, thus preventing stress corrosion of the fuel can, esp. at the bulges produced by swelling of the pellets at their upper and lower circumferential edges.
Patent DE-2549322-A1 (DE)
Title: Rendering synthetic or natural leather supple - by alternately applied shear stresses perpendicular to transport direction
Inventor: DOKOUPIL JIRI
IPC: C14B1/40
Filed: 1975-11-04
Abstract: In the continuous softening and fibre opening of flat materials, the material is processed as multiple strip elements running transversely to the direction of transport at the minimum spacing corresponding to the advance within each oscillation, by stressing in shear in alternating directions in the plane of the material. The strip elements are transported at the instant when they are released from tension. This solves the problem of rendering supple materials with only slight expansion capacity, which cannot be treated by the usual leather staking tools without risk of tearing.

Title: High speed plating of metal with nickel layer - using insoluble anode and controlling nickel ion concn in bath
Inventor: TEZUKA JUNICHI
IPC: C25D3/12
Filed: 1976-05-07
Abstract: A high speed Ni plating process uses an insoluble anode made of e.g. Ni which does not cause a passive state, and the supply of nickel ions into the bath is controlled by the detected pH value of the bath not by the amt. of dissolution of the anode, so as to adjust the pH and Ni ion density in the bath. The supplying Ni ion-contg. contg. soln. is prepared by reacting Ni flakes with a bath in a nickel ion supplying apparatus according to the detected pH value. Plating can be carried out with a high current density of 70 A/dm2 max. without losing the properties of the deposited Ni layer. It is possible to continuously seed the stable Ni plating bath soln. into a bath. When plating Ni on a solder layer, good adhesion can be obtd. between a solder and Ni plated layer without forming a copper strike between the solder layer and Ni plated layer.
