Abstract: A current-limiting switching element, for whose at least one contact set comprising a movable and a fixed contact member, a device for providing an auxiliary magnetic field is arranged with an axis perpendicular to the direction of the extent of the movable contact member. It is provided that the direction of motion of the movable contact member lies in the direction of the axis of the device for providing the auxiliary magnetic field. The direction of the current to the contacts is chosen so that the movable contact member is subjected to a force repelling it from the fixed contact member with respect to the auxiliary magnetic field.

Abstract: For the recycling of electrical batteries, in particular of a mixture of high-power batteries for equipment of any chemical composition, and also of assembled printed circuit boards and electronic components, a pyrolysis of the unsorted mixture is carried out at a temperature between 450 DEG  and 650 DEG , then an electrolysis of the pyrolysis slag is carried out and subsequently a separation of the electrolysis products and removal of the products accumulating at the electrodes is carried out. In this process, which is economically profitable, no environment-polluting residues are produced and an initial sorting of material becomes unnecessary.

Title: Holder for molten metal sampling device
Inventor: HAUGHTON GARY H
IPC: G01N1/12
Filed: 1990-01-04
Granted: 1995-02-07
Abstract: A holder for a molten metal sampling device includes a pipe having a guidance chamber in a lower portion and a molten metal sampling device in an upper portion.  The pipe is open downwardly and a closure element closes the opening.  The closure element has a density such as to cause it to float upwardly in the molten metal being sampled.  A protective cover, preferably of two parts, encloses the closure element and a lower portion of the pipe.  A retaining device such as a spring clip holds the separate parts of the protective cover together around the closure element and the lower part of the pipe.  The retaining device is adapted to fail upon contact with the molten metal, thus releasing the portions of the protective cover so that they will separate and float upwards, whereupon the closure element also separates and floats away, allowing molten metal into the guidance chamber and the sampling device.

Title: Re-processing incinerator ash
Inventor: SHERIDAN JOHN PATRICK
IPC: C05F15/00
Filed: 1990-02-26
Granted: 2000-08-15
Abstract: The present invention provides methods for re-processing incinerator ash to recover phosphates and minerals therefrom. The incinerator ash may be agitated in a bath of sulphuric acid - which may be diluted or concentrated. The process may be carried out at elevated temperatures and/or pressures. Because the incinerator ash contains high concentrations of phosphates of calcium, magnesium, aluminum, or any of them, the agitated mixture will have phosphate-containing compounds, which may then be separated from it. Thereafter, optionally the residue following the separation of the phosphate-containing compounds may be purged of any trace metallic elements that are present in it; and further optionally the residue may then be died and re-ground followed by a cyanide process separation of precious metal elements that are in it. Still further, the residue following the precious metal separation process may be dried to form an aggregate, which once again may have phosphate-containing substances that may be separated from use as fertilizers. In any event, the aggregate may be then mixed with cement so as to form cement-based rigid and solid products such as cement blocks or the like.      Cement-based products having this aggregate tend to be less dense than ordinary cement-based products, they set up quickly, they have a better co-efficient to heat transfer, and they may present a semi-polished appearance at their exposed surfaces.

Abstract: An improved Packet Assembler/Disassembler (PAD) optimizes the assembling of characters into packets for transmission over a packet network. The PAD is arranged to operably connect to and receive character asynchronous data from one or more terminal instruments operating in either a block transfer mode or an  echoplexing  mode.  Characters received by the PAD from a terminal instrument operating in an echoplexing mode are forwarded with no PAD delay. Characters received by the PAD from a terminal instrument operating in a block transfer mode are similarly forwarded with no PAD delay and in full packets withthe exception of the last few characters of each block of characters which only partially fill their respective packets.  And these partially filled packets are quickly forwarded  in   a time period which  just exceeds the  period required for the reception of a single character at the rate of data reception from the terminal instrument.

Title: Apparatus and method for a catheter adapter with valve
Inventor: PURDY EDMUND R
IPC: A61M25/00

Granted: 1994-11-01
Abstract: CATHETER ADAPTER WITH VALVE     ABSTRACT OF THE DISCLOSURE       An over the needle catheter with adapter that has an integral valve in a passage.   Distal and proximal parts form  the  adapter  along  an  axis.   The  distal  part communicates with a catheter.  A hub conjugates with the proximal part and has a needle extending along the axis and  through  the  passage  when  the  hub  is  within  the proximal part.  A valve assembly has an elongate resilient member  captured  in  the  passage  between  the  parts.   A proximal  portion of  the valve assembly is engaged by a fitting to open the valve.  A valve seat in the passage has  a  frusto-conical  surface located coaxial  about  the axis  and facing the  distal  part.   The  seat  engages  a chamfered surface on the elongate resilient member to seal and prevent flow and to allow flow when the seal is broken by axial compression of the elongate resilient member by the  fitting.   A  septum  like  end  across  the  elongate resilient member permits the needle to pass therethrough in a resealable fashion.   The  elongate  resilient member has a diametrically reduced cylindrical body extending to the septum like end.   The passage has  an annular  space about the reduced cylindrical  body  and terminates in a distal  area.   The distal area  has  flow  channels  which extend between the annular space and the distal part.  A method has steps of locating the parts along an axis and capturing the  elongate  resilient member by engaging the axially  aligned  parts  to  force  the  elongate  resilient member against a valve seat for sealing the passage and preventing flow.  Placing a needle carried on a hub along the axis and through a septum like end of the elongate resilient member allows the needle to be withdrawn from the septum like end and to reseal the passage.  Applying fastening means to secure the parts is a step.

L'invention comprend les étapes et l'appareil de transfert des dispositifs de fixation à partir d'un mécanisme d'amenée, de sorte que les dispositifs de fixation sont positionnés pour être enduits. Lesdits dispositifs de fixation sont ensuite transportés dans une pluralité de postes de commande, commençant avec un poste de chauffage où les parties de tige des dispositifs de fixation sont chauffées. Ensuite, au niveau d'un poste d'application de matière, une matière de revêtement est appliquée sur les parties de tige chauffées. Un mode de réalisation préféré du procédé et d'un appareil de l'invention, consiste à utiliser un support magnétique afin de transporter les dispositifs de fixation horizontalement par leurs parties de tête, à chauffer la partie de tige jusqu'à une température supérieure au point de fusion de la matière appliquée, et à appliquer la matière à la partie de tige chauffée afin de former un revêtement sur cette dernière. Les supports magnétiques font partie d'une bande de transport sans fin en rotation continue. Les supports des dispositifs de fixation comportent des dents s'engageant dans une crémaillère afin de mettre en rotation les dispositifs de fixation. Un convoyeur assure un refroidissement par air supplémentaire aux dispositifs de fixation enduits, lesquels peuvent continuer à tourner. L'invention concerne également une roue de transfert dotée de deux ensembles d'entailles, laquelle est couplée de manière synchrone à la bande de transport afin de placer et d'aligner les dispositifs de fixation sur la bande pour les enduire.
