Patent DE-3470073-D1 (DE)
Title: A cylinder lock
Inventor: SJUNNESSON BENGT O
IPC: E05B9/04
Filed: 1984-12-19
Granted: 1988-04-28
Abstract: A cylinder lock (1) has a normal locking mode (12 o'clock position) and a service locking mode (10 o'clock position). When the cylinder plug (3) is left in the service mode of the lock, with the aid of standard key, the lock can be turned with the aid of a service key (9). The service key is latched against withdrawal in the normal mode of the lock, by means of an intermediate pin (7') of larger diameter than a corresponding upper pin (4) in the normal mode of the lock. The intermediate pin can be received in a widened part (3b') of a corresponding pin-channel (3a') in the cylinder plug, but is unable to enter the pin-channel (2a) of the cylinder housing of smaller diameter, hence latching the service key (9). Subsequent to using the service key (9), the cylinder is returned to the normal locking mode (12 o'clock position) with the aid of the standard key, whereafter the lock can only be opened with the aid of the standard key. Each of the two modes can be defined by a spring-biased ball disposed in a suitable pin-channel and arranged to snap-in a corresponding empty pin-channel in the plug.

Title: Vacuum treating steels
Inventor: MULCAHY JOSEPH
IPC: C21C7/10
Filed: 1984-11-28
Granted: 1989-02-16
Abstract: Molten steel or other electroconductive metal is treated with vacuum to remove dissolved gases therefrom. A rod (28) of molten steel is drawn from a bath (14) by applying vacuum to a vertical tube (22) dipping into the molten bath (14). An electrical coil (26) surrounding the tube (22) applies an intense magnetic field to the steel rod by the passage of high frequency alternating current through the coil (26). The rod (28) is compressed radially inwardly by the magnetic field exposing the whole of the external surface of the rod (28) to vacuum. At the same time, the induced eddy currents superheat the steel rod. The large surface area of application of vacuum combined with the narrow dimension through which the gas must travel ensure rapid and efficient removal of the gases. The procedure is repeated until all the steel in the bath has been treated. Lack of contact of the steel rod (28) with the tube surface eliminates loss of heat by convection and the superheating of the steel rod by the eddy currents ensures that the overall heat losses are minimal during processing of the molten metal bath.

Abstract: The method relates to the hardening of form substances made of building materials and containing binding agents in a pressure chamber of an autoclave to which is conveyed a gaseous heating medium, the temperature of which is increased during a heating-up phase up to a given upper limit value. During a holding phase, the temperature is maintained at least until a given equalization temperature is reached on the inside of the form substances. Subsequently, during a cooling-down phase, the temperature is reduced by reducing the pressure to the expulsion temperature. Porous light building materials in a conventional process would absorb a high amount of water through the condensation of water resulting from steam having been conveyed into the autoclave for the purpose of hardening. However, in order to produce form substances of a low water content economically, according to the present invention, on the one hand, steam is replaced by gas which is maintained below the evaporation temperature of water through sufficient increase in pressure, and, on the other hand, as a replacement or complement, heat is conveyed to the inside of the pressure chamber before the cooling-down phase and an increase in the temperature of the steam beyond the given limit value is prevented by blowing off steam, thereby attaining an integrated drying process.

Title: Method for regenerating a soot filter in a diesel internal-combustion engine

Granted: 1988-11-17
Abstract: 1. Method for the systematic burning-off of solid particles (soot) formed and collected in a filter (12) from the exhaust gas stream of a diesel internal combustion engine, such as for example a diesel engine of a machine, in which case a throttle valve (4) provided in the suction pipe (2) for the combustion air is actuated inter alia depending on the counterpressure (PVF) measured in the exhaust gas pipe (11) in front of the filter (12), according to the following system, with the machine stationary ; The counterpressure (PVF) measured during idling of the diesel engine (1) is compared with a given upper limiting pressure (PG1) (step 1). If the counterpressure (PVF) exceeds the upper limiting pressure (PG1), then a first signal (PVF > PG1) is produced, whereupon the diesel engine is run in the upper partial load operation (step 2). During the continued load operation of the diesel engine, the exhaust gas temperature after the filter (TNF) is measured and compared with a given, first temperature value (TG1) (step 3). If the exhaust gas temperature (TNF) exceeds the first temperature value (TG1), then a second signal (TNF > TG1) is produced, whereupon the throttle valve is actuated in a throttling manner (step 4). If the operation of the diesel engine (1) is continued in the upper partial load range, the counterpressure (PVF) is again measured and compared with a given lower limiting pressure (PG2) (step 5). If the counterpressure (PVF) falls short of the lower limiting pressure (PG2), then a third signal (PVF < PG2) is produced, whereupon the throttle valve (4) is again opened and the load on the diesel engine can be removed (step 6).

Abstract: This invention relates to a terminal by means of which users may communicate in a secure fashion with a second party, eg a bank, in order to transact business, eg transfer funds. The user must be verified to the second party before business can be transacted; and it is advantageous if, in addition, the terminal is able to verify the second party that is genuine. In order to achieve this verification the terminal encrypts information about the user's identity using a selected key, then encrypts the selected key using a public key, corresponding to a secret key held by the second party, before transmission. The selected key may be a conventional key or a second secret key corresponding to a second public key. Multiple encryptions of the selected key are also described. In a preferred embodiment the terminal also sends a cryptographic checksum to the second party based either on the selected key or a secret key. The invention also includes a system using such a terminal.

Abstract: A method which involves the isolation, analysis and characterization of dispersants present in motor oils is disclosed. The method is particularly useful in connection with the characterization of high molecular weight polybutenyl succinimide dispersants present in finished motor oils so as to provide detailed information with respect to the starting material reactants needed to synthesize such dispersants. The method involves breaking down complexation present in the oil followed by the isolation of the dispersant from the oil via dialysis. The isolated dispersant in the form of a dialysis residue is then acidified and passed through an ion exchange chromatographic column to adsorb acid materials away from the dispersant. Dispersant content and total carbonyl content can then be determined. The dispersant is then subjected to saponification with sodium hydroxide to provide a hydrocarbyl sodium succinate and a polyamine. The saponified material is subjected to further dialysis to separate it from remaining oil and then further acidified. The acidification results in the formation of a corresponding succinic acid and a dialkyl ester derivative. Procedures such as GPC and VPO determinations can then be carried out. Model reactant components can then be prepared and reacted to determine if the reaction product obtained matches the original dispersant being analyzed.
