Patent DE-69839592-D1 (DE)

Abstract: The invention relates to refractory materials particularly recycled waste material removed from furnace linings. Spent furnace linings have contaminants making the material unsuited to further use in a brick or compact making batch. The object of the invention is to provide an economic treatment process rendering such spent furnace lining materials suitable for further use, which objective is met by a process for the treatment of material reclaimed from a refractory lining after the end of its useful life in which superheated steam is applied to particulate feedstock material formed from the reclaimed material whilst maintaining the feedstock material at an elevated temperature in a suitable vessel. The superheated steam may be introduced into a flow of particulate feedstock material, such as, for example, by injecting the superheated steam into the particulate material. <IMAGE>

Abstract: A replaceable roller turns on an axle supported at the end of a cantilever arm. The roller is preferably brass or other highly conductive, durable material for making electrical contact with a terminal of an electrical device, e.g. a ceramic capacitor. The arm is made from a highly conductive, resilient material. There are a plurality of such arms with rollers connected in parallel to a holding module, preferably with the rollers aligned. The holding module is secured to a structure, e.g. a component test handler jig, and provides a conductive path between each roller/cantilever arm assembly and the test jig. In operation a stream of components are indexed to the rollers such that their terminals are aligned with the rollers. The rollers intrude slightly into the path of the compnents so that as they are indexed to the rollers, the components deflect the rollers causing them to roll across the components' terminals. The resilience of the cantilever arms presses the rollers against the terminals to make good electrical contact. Preferably the roller/cantilever arm assemblies are easily disconnectable from their holders so they can be quickly replaced when needed, and this patent describes such a preferred connection mechanism.

Abstract: A gas spring device is provided with a safe and effective way to reduce to zero the velocity of a piston rod which is traveling at a high velocity in the gas spring device during a failure of the gas spring device. This achieved by stopping the piston rod in a controlled manner through a stepwise reduction in its energy and velocity to keep the force on the piston to a minimum at all times during the failure. The reduction in energy is caused by a plurality of frangible components associated with the gas spring device which are designed to break during a failure, thereby dissipating the kinetic energy of the piston rod.

Abstract: A directly compressible starch consisting in an intense white free-flowing powder showing both excellent compression profile and extremely good disintegration properties. This starch is especially designed to be used as a binder in direct compression processes where it yields very hard white tablets at relatively low compression forces. Tablets resulting from the compression of the above mentioned starch disintegrate in an aqueous medium at a very high speed and they additionally exhibit low friability pattern. This free-flowing starch also brings advantages when used as filler and binder in the filling of some hard gelatine capsules especially for these which are filled by pre-compression of the ingredients. This starch is characterised by regular and smooth partially swollen granules which can be either birefringent or non-birefringent. It can be prepared by spray-drying of a partially cooked starch.

Abstract: A device (5) for triggering a handover or for adjusting transmit power levels in a cellular communications system distinguishes between the use of a frequency hopping or a non-frequency hopping channel and sets a different threshold value depending on which type of channel is being used. In one embodiment, handover trigger levels for hopping channels are based on frame erasure rate measurements rather than bit error rate measurements thereby avoiding unnecessary handovers and advantageously reducing signaling traffic.

Abstract: A technique for generating, for a given message to be signed, an authentic cryptographic signature that can be authenticated, by a recipient of the signed message, as having originated from a signor of the message; and appropriately authenticating such a signature. Specifically, this technique, given a message, such as, e.g., a numerical product copy identifier (83, 93), forms an authentic signature (87, 97), based on public-key cryptosystem, through use of generator value selected from points on an elliptic curve over a finite field. The authentic signature is generated using the generator value in conjunction with three keys; namely, a public key, a private key and a secret key, and thus substantially increases the security associated with cryptographic signatures generated through a conventional two-key public-key cryptosystem. A unique product copy indicia can be formed by concatenating the identifier, for a given product copy, with its corresponding authentic signature. During subsequent user installation of that copy to a computer (200), the user enters the indicia when prompted by execution of an installation program which, in turn, privately authenticates the signature contained in the indicia in order to continue or prematurely terminate the installation.

Abstract: A PEMF therapy system uses a bi-phasic coil PEMF transducer for generating PEMF stimulation signals. The coil has a "bi-phasic" operation, such that current flows through it in two directions. A drive circuit recovers the flyback energy from the transducer coil and dumps voltage to an energy recovery capacitance circuit. The transducer is thereby energized and de-energized to provide the electromagnetic field. The same concepts are applicable to series-connected coils. The transducer is especially suited for high frequency operation.

Abstract: A bonding process is employed in the assembly of e.g. automotive components whose pre-bonded interfaces bear contaminant residues. The bonding agent is applied to the interface zone and the components are assembled. During the adhesive curing process, the bonding agent is exposed to microwave energy in the range 20 to 100 kHz. The ultrasonic energy promotes the separation of residual contaminants from the work piece bonding surfaces and causes these to disperse within the bonding matrix. The ultrasonic energy is imparted by the application of a probe to the work piece and/or adhesive, simultaneously with the injection or application of the bonding agent at 35-70C by an industrial robot. The adhesive is a twin-component agent applied at room temperature, or an adhesive that cures under heat exposure, or a single-component adhesive.
