Title: Fast reactor fuel assembly with gas collecting chamber - partly housed in shaft has reduced length and pressure drop
Inventor: ILJUNIN VLADIMIR GRIGOREVITSCH
IPC: G21C3/32
Filed: 1976-12-15
Abstract: A fissile material assembly for a fast neutron reactor comprises an outer casing, with a headpiece at one end and a shaft at the other end, the fissile material elements contained in the casing are associated with gas collecting chambers for receiving the gaseous fission prods. These gas collecting chambers are subdivided into a central gp. and a peripheral gp. At least one of these gps. of gas collecting chambers is in the shaft of the fuel element upstream of the fissile material elements. Used for a fast neutron reactor. The arrangement of the gas collecting chambers, some of them in the shaft of the fuel element, permits a redn. of 20-30% in the overall length and pressure drop through the fuel assembly. In addn, the proportion drop through the fuel assembly. In addn, the proportion of structural material required for the assembly is considerably reduced.

Title: Decorative pattern printed onto adhesive plastic foil - then applied to porcelain prods. prior to baking
Inventor: MANN WOLFGANG DIPL ING
IPC: B44C1/17
Filed: 1977-11-17
Abstract: Decoration is applied to prods., esp. porcelain tableware, crockery, enamel, and onto metal coated with vitreous enamel. Conventional printing processes are used to apply pigments or noble metal patterns onto thermoplastic foils with adhesive properties. The foil is applied to the substrate surface using 1-2 seconds at 140-190 degrees C to obtain uniform adhesion, followed by baking at (a) 750-850 degrees C for silicate ceramics; (b) 800-820 degrees C for steel sheet coated with vitreous enamel; or (c) 530-550 degrees C for enamelled aluminium. After baking, no residue is left from the adhesive foil but the decoration is in the required posns. An adhesive is pref. used with viscosity 84,600-2600 cP, between the substrate and the printed foils, which are pref. precut to size and heating may be applied in steps of 50 degrees C. The silicate or porcelain substrate may be unbaked, or glazed and baked, before the foil is applied. Substantial cost savings can be achieved; productivity and quality are increased; and mfg. methods are simplified, esp. in mfg. porcelain tableware.

Title: Ultrasonic surface region fault detection - using focussed longitudinal waves from inclined test heads and pulse-echo reception
Inventor: WUESTENBERG HERMANN DR ING
IPC: G01N29/04
Filed: 1978-01-19
Abstract: A non-destructive testing device is for faults near the surface in metallic material using ultrasonic waves. It is suitable for rough cast or roughly cut material for which Rayleigh surface wave techniques are not reliable. Longitudinal waves (4) flowing along the surface (3) or creep wave, are used. These are produced by test heads (1) near the surface. Faults are detected using pulse-echo reception with the test heads inclined at an angle to the surface to produce total wave reflection.

Title: Vehicle-seat belt retractor - uses sensor signal actuated pressure medium acting directly on webbing
Inventor: BRUNKEN GERD ING GRAD
IPC: B60R22/28
Filed: 1978-04-12
Abstract: The retractor mechanism uses a pressurised expanding medium triggered off by a sensor signal and the pressure of the expanding medium acts directly on the webbing of the seat belt. The webbing (2) is led through slots of the rectangular section retractor body (1) the smaller sides of the body having serrations (8). The larger side of the rectangular cross section corresponds with the width of the webbing (2). Underneath the webbing is a cylindrical actuator (9) containing a two-part spring loaded pin with a tendency to expand towards the serrated surfaces (8). When the pressurised compound in container (4) is actuated the cylindrical body (9) is pushed upwards against the webbing (2) forming a loop and shortening the seat belt length. At the same time the spring loaded ends of pin (7) engage with the serration (8) and block the belt.

Title: Reversible grill assembly for cooking on open fire - has food placed on one side and other side is pinned in position and held against stop by off-centre pivot
Inventor: CLAIRE GEB MAGOT SOLANGE ODETT
IPC: A47J37/04
Filed: 1978-05-16
Abstract: The grill is used for cooking over an open fire and can be reversed to cook on both sides. It comprises a bottom grill (4), having pivot bearings (8) on its inner face. A spindle (2) passes through these, enabling the grill to be turned over. The food (6) is placed on this side and another grill (5) is fitted over it, located by rings over projections (15, 16). A pin (19, 20) passes through one of several holes in each projection to hold the assembly. The pivot is located off centre (B, C) on the bottom grill, causing an unbalanced force which holds it against a stop (3, 4) on the pivot.
Patent DE-2822914-A1 (DE)
Title: Semi-rigid lock for small firearm breech block - has sliding wedge in breech block rear locked by roller
Inventor: BUDISCHOWSKY EDGAR
IPC: F41A3/46
Filed: 1978-05-26
Abstract: The breech mechanism of a small firearm has an integral unit consisting of a handle with barrel and cartridge chamber. The breech block is held firmly until the bullet has left barrel for full utilisation of gas pressure. The breech block is released immediately after the bullet has left the muzzle. The breech block locking roller is held in a transverse horizontal groove and is in contact with an inclined plane of the locking wedge sliding within the breech block. The longitudinal movement caused by the recoil jams this arrangement. The acceleration in longitudinal direction opposite that of the firing direction ensures the opposite movement for the locking wedge and releases the locking roller from its groove so that the breech block is released. The breech block moves backwards and the cartridge case can be ejected.

Title: Vibrator assisted grain milling equipment - uses shaped milling body adjacent rollers to give constantly varying milling gap
IPC: B02C1/08
Filed: 1978-06-21
Abstract: The milling equipment has a concave milling body (2) supported against the upper roller (3) of a pair of milling rollers, the lower roller (5) being vibrated. The curvature of the inside face of the milling body is greater than the armature of the upper roller, so that the gap between them is wider at the top than at the bottom. The milling body is mounted on a horizontal spindle (1) at the bottom and is connected to a set of vibratory motors (10) at the top so that the vibrations cause the size of the gap to be continuously varied. When used for wheat and other delicate materials, the arrangement gives an improvement in the quality of the product. The size of the gap can be varied to suit the material to be ground.

Title: Tamperproof breathalyser - with carbon di:oxide analyser to prove hyperventilation attempts
Inventor: TERVEEN AXEL DIPL ING
IPC: G01N33/497
Filed: 1978-08-23
Abstract: A breathalyser to measure the alcohol concn. in the blood includes, apart from the alcohol measuring unit for the respiratory air, a CO2 analyser of this air. The latter indicates that the alcohol measurement is valid by a signal that the CO2 content exceeds a certain threshold (4.5%). This frustrates attempts by suspected persons to falsify the readings by hyperventilation, i.e. by 3-4 rapid and deep breaths in and out.
