Title: Dispositif de comptage de cartes à puce contenues dans un lot
Inventor: DUPRE FRANCOIS CABINET BALLOT-
IPC: G02B27/00
Filed: 1991-07-25
Abstract: Pour compter des cartes à puces (1,2) au moment de la fabrication, on choisit de présenter (6) ces cartes à puces dans des lots, sur chant, dans le champ d'un rayonnement X. On mesure l'image (9) différentielle d'atténuation du rayonnement X due au passage de ces rayonnements X d'une part à travers les corps de carte en plastique, relativement transparents au rayonnement X, et d'autre part au travers des parties métalliques (21) de connexion des puces (20). Dans l'image d'absorption radiologique obtenue on compte le nombre de transition (15) du signal d'absorption. On montre que la fiabilité de comptage est grandement améliorée de même que la sécurité de manipulation. <IMAGE>

IPC: H05H11/00
Filed: 1991-10-14
Abstract: A compact circular magnetic induction accelerator (betatron) for use as a borehole gamma ray source includes a field magnet and generally circular pole pieces composed of a class of ferrite having the general formula M²⁺F₂³⁺O₄, where M represents two or more divalent metal ions from the group consisting of Mn, Zn and Ni. The core magnet is in the form of two symmetrical closed loops, with one leg of each loop passing axially through the circular pole pieces. The field coil and the core coil may be arranged in series or in parallel, and switching circuits are provided for effecting electron beam capture and ejection. In an illustrative borehole application, the betatron is used as a gamma ray source in a bulk density logging tool.

Title: Mechanism for controlling the firing rate of an automatic weapon.
Inventor: EALOVEGA GEORGE
IPC: F41A19/33
Filed: 1990-12-17
Abstract: A trigger mechanism for controlling the firing rate of a gun (10) capable of fully automatic fire. The trigger mechanism comprises a timing device (54, 56) which cyclically interrupts the gun bolt (14) and is incorporated in the gun. The timing device (54, 56) is actuated independently of forces generated by the discharge of the gun so that the bolt (14) periodically is arrested to reduce its natural cyclic rate of movement during automatic firing.

Title: Electrolytic removal of tin oxide or titanium nitride from a coater.
Inventor: GORDON ROY GERALD
IPC: C25F5/00
Filed: 1991-02-15
Abstract: A method for electrochemically removing tin oxide from a coater surface. A tin oxide coater is placed in an electrolytic bath to function as the cathode of a pair of cell electrodes. The tin oxide is electrolytically removed by either reducing the tin oxide to tin metal and then dissolving the tin, or creating a bubble of hydrogen gas at the coater surface/tin oxide interface. Pressure of the hydrogen gas forces the tin oxide to break away from the coater at the coater surface/tin oxide interface.

Title: Process for making small preserved sausages and preserved sausages so made.
Inventor: NIEDERMANN FRITZ
IPC: A23L13/60
Filed: 1991-11-13
Abstract: To make the sausage, salt, pickling and a filler are added to lean meat which is chopped and then mixed with pieces of meat and bacon in grain form. Unlike the ordinary process of producing preserved sausages, the lean meat is then very finely minced. The filling is then inserted into the skins, forming sausages about a metre long. After being smoked the sausage compound is heated to coagulate it. The sausages are then skinned, hung on racks and dried until about fifty per cent of the weight is lost. The preserved sausage thus made is cut up and the pieces are preferably packed individually in transparent packages. A number of such transparent packages are connected together via perforations.

Inventor: RAMSTETTER ASBJOERN DR
IPC: F01N3/20
Filed: 1992-05-08
Abstract: Conventional devices for the denitration of the exhaust gases of an internal combustion engine (4) which operate according to the principle of the selective catalytic reduction provide a reservoir (14), carried along in the vehicle, for, for example, an aqueous urea solution (16). The ammonia forming in the reservoir during heating of the aqueous urea solution is conventionally discharged to the surroundings for the pressure relief of the reservoir. This liberation of the ammonia is disadvantageous since ammonia is toxic and, even in low concentrations, represents odour pollution for people. For this, according to the invention it is proposed to connect to the reservoir a pressure-relief line (18) via which excess ammonia can be fed to the DeNOx catalyst (8) and is joined to the catalytic material. The invention can be installed in principle in any device for denitration of the exhaust gases of an internal combustion engine. <IMAGE>

Filed: 1992-05-09
Abstract: The invention relates to a method for severing the rovings (15) on roving bobbins (6) produced on roving frames (1). According to the invention, the roving frames (1) are stopped in a position in which the press fingers (5) bear on the cylindrical region (18) of the roving bobbins (6). Subsequently, the bobbin rail is lowered, and at the same time the roving bobbins (6) are rotated in reverse. This is followed by a short forward rotation of the roving bobbins (6) and by an accumulation of roving material by a brief switch-on of the drawing unit (13). Lastly, the bobbin rail (8) is raised again and the rovings (15) are thereby severed level with the cylindrical region (18) of the roving bobbins (6). <IMAGE>

Abstract: The invention relates to a boiler for burning liquid or gaseous fuels, consisting of a water-conducting housing, in which a combustion chamber (3) equipped with a burner (2) is arranged, from which a number of waste gas flues (4) lead to the waste gas collecting chamber (5), in which flues waste gas displacement bodies (6) are arranged, of which the displacement body (6) in at least one of the waste gas flues (4) is designed as waste gas return pipe (20) which discharges openly towards the waste gas collecting chamber and the other end (8) of which is connected to a connection opening of the combustion chamber closure (10), which is provided with a heat insulation body (19), and from there is connected to the burner (2). According to the invention, it is envisaged that the connection opening, which is designed as an intervention opening (9), is dimensioned larger in cross-section than the waste gas return pipe (20), and that there is arranged in the intervention opening (9) an axially and elastically displaceable sealing ring (21) which is guided on the wall of the intervention opening (9) and which in the closed position of the combustion chamber closure (10) bears against the end (8) of the waste gas return pipe (20). As a result, there are no problems on opening and closing the combustion chamber closure (10) and a constant seal is guaranteed between the waste gas return pipe (20) and the combustion chamber closure (10) or the intervention opening (9). <IMAGE>

Abstract: Method for forming a container blank from pulp material using a mould, said blank comprising walls and a bottom. The object is for the end container product to have relatively straight walls. Since in the moulding of paper pulp a certain tapering of the walls during their moulding is necessary to maintain clearance of the mould, provision is made according to the invention for a container blank with relatively inward slanting walls and with an in some way curved bottom to be made first, following which the curve is removed from the bottom when the walls are moved apart, so that a container with straight walls is produced.
