Patent DE-4240346-A1 (DE)
Title: Field emission electron source mfr. - forming silicon nitride and chrome layers on silicon wafer, and  etching to form central cathode tip
Inventor: WINKLER DIETER DR
IPC: H01J9/02
Filed: 1992-12-01
Abstract: The field emission electron source is formed from a silicon wafer (1) onto which a film of silicon nitride is deposited (2). A vapour deposition process creates a metal anode (3'), typically of chrome. A ring structure for the anode is produced by photo-etching the chrome film. A further plasma etching process is used to penetrate the silicon nitride and so creates channels. A further etching process removes the centre section to create an accurate cathode tip (8). USE/ADVANTAGE - E.g. for modulatable surface emitters/arrays. Does not require precise adjustment of anodes and cathodes.

Patent DE-4331002-A1 (DE)
Title: Laser mass spectrometer
Inventor: SCHMITT CHRISTOPH DR
IPC: H01J49/16
Filed: 1993-09-13
Abstract: The invention relates to a laser mass spectrometer which has high senstivity and mass resolution as a result of a suitable arrangement and miniaturisation; this is achieved by means of a particular arrangement of a detector, reflectron and laser beam in conjunction with optimisation of the dimensioning of these elements. As a result of the particular laser-beam routing, local measurements (lateral measurements as well as depth profiles) can be measured on the sample. The spectrometer further has a sample-handling unit which permits fast transfer inwards of samples and thus a rapid analysis of large sample sizes. Due to its miniaturisation, the mass spectrometer can also be used in a mobile manner. <IMAGE>

Patent DE-4407310-A1 (DE)
Title: Process to control heat treatment distortion in mfr. of needle bearing
Inventor: DOEPPLING HORST
IPC: F16C33/60
Filed: 1994-03-04

Title: Multi-stage fan for car, with control resistors on carrier plate attached by spring clips
Inventor: HEINZE HANS-JOACHIM
IPC: F04D29/58
Filed: 1994-03-28
Abstract: The multi-stage fan uses a carrier plate with the resistors sitting in the air stream on one side and power connections on the reverse side. The resistors (25) protrude through a hole in a wall bounding the air stream, beneath a cover(24), there being a seal between carrier plate and wall.  On the side of the plate (21) facing the wall there is a sealing surface (36,37) and the edge of the opening has a corresponding sealing surface. The clip (26) squeezes the two surfaces together. The sealing surface on the plate is conical and that on the wall is funnel-shaped.
Patent DE-4412257-A1 (DE)
Title: Automatic, revolver-like firearm, as well as a metal caseless projectile for such a firearm
Inventor: GIESE RUEDIGER
IPC: F42B3/113
Filed: 1994-04-07
Abstract: The invention relates to an automatic, revolver-like firearm having a barrel (1), a tubular magazine (2), a drum (3), a laser (6) which is arranged in the stock (5), an accumulator (8) and an electronic control device (9) which is accommodated in the weapon frame and in the handles, as well as a metal caseless projectile (10) for such a firearm. The object is to achieve a high rate of fire and very fast loading times. The tubular magazine (2) contains projectiles (10), stacked in five magazine tubes (11), having a projectile base (13) through which a laser beam can pass and having a firing charge (22) which is fired by laser pulses and initiates the combustion of the propellant charge powder (18). A plurality of projectiles (10), which leave the drum (3) and the barrel (1) without any coarse body residues, are fired successively in the rotating drum (3). After a specific final cycle, the electronic control device (9) causes all the drum chambers located under the barrel axis to be loaded simultaneously with new projectiles (10) from the tubular magazine (2), using the muzzle-loader principle. As a result of this rational cycle (firing of a plurality of rounds successively, avoiding having to get rid of cartridge cases, and simultaneous reloading of a plurality of projectiles) allows a theoretical rate of fire of 5600 rounds per minute to be calculated (Figs. 1 and 5). <IMAGE>

Abstract: L'ouvrage annulair de maçonnerie interne (11, 11a), situé au-dessus des ouvertures du carneau à gaz (19), est réalisé en tant que corps indépendant et suspendu sur le bord supérieur du manteau en maçonnerie (5) à l'aide d'ancrages tubulaires (12, 12a). La sollicitation due au poids est transmise des ancrages (12, 12a) à des supports qui s'appuient sur le bord supérieur du manteau (5). Les ancrages (12, 12a) peuvent être situés à l'intérieur ou à l'extérieur de l'ouvrage annulaire (11, 11a). S'ils sont disposés à l'intérieur, un fluide de refroidissement est fait circuler à travers ces ancrages tubulaires (12). Les ancrages extérieurs (12a) sont avantageusement réalisés par des tubes parallèles qui sont reliés sur toute leur longueur par des entretoises de manière à former un anneau d'acier fermé. Par la présence des tubes annulaires (33, 34) soudés sur les extrémités supérieure et inférieure, l'anneau d'acier forme en même temps un échangeur de chaleur et est relié dans la partie d'évaporation de la chaudière de récupération du refroidisseur de cheminée. Cette configuration de l'ouvrage annulaire offre entre autre l'avantage de pouvoir renoncer aux parois de soutènement jusqu'ici nécessaires et très sensibles aux perturbations, dans la zone des ouvertures du carneau (19). Sur le bord inférieur de l'ouvrage annulaire (11, 11a) sont prévues seulement des entretoises d'appui (18) disposées radialement et espacées les unes des autres, qui délimitent les ouvertures du carneau (19); les entrées des ouvertures du carneau (19) sont ainsi situées à peu près dans le plan ou au-dessus du bord inférieur de l'ouvrage annulaire (11, 11a).
