Patent ES-414224-A1 (ES)
Title: Cartridge ejection device for an explosion driven setting gun
IPC: B25C1/10
Filed: 1973-04-30
Abstract: In an explosion driven setting gun, spent cartridges are ejected from a cartridge chamber by a pivotally mounted ejection lever when a front part of the gun containing the cartridge chamber is pivoted relative to a rear part. To assure proper ejection, during the pivotal movement as the gun parts are opened, a locking member holds the ejection lever until a spring biased stop member exerts a predetermined load on the ejection lever causing it to be released from the locking member. Upon such release, the spring biasing action of the stop member causes an accelerated pivotal movement of the ejection lever with the resultant ejection of a spent cartridge.

Title: Transit exchange for time division multiplex asynchronous data
IPC: H04L12/52
Filed: 1974-08-09
Abstract: The present invention relates to a transit exchange for the transmission of asynchronous data signals having a given character structure and data rate, with the aid of a control equipment, including a computer and a sampling device, which is common to a number of sending terminal equipments and works on the time division multiplex principle. The instantaneous values of the data signals received over each of a number of incoming lines are sampled at a frequency so selected in relation to the asynchronous data rate that at least one sampling pulse falls within a distortionless region of the respective character element. The transit exchange includes a detector working synchronously with the sampling device to establish, by means of the successive processing of the sampling pulses, the binary value of each character element. Corresponding binary indication values are stored in an intermediate memory at an addressed location associated with the receiving terminal equipment and from there are transferred cyclically by a read-out device to a regeneration device corresponding to the receiving terminal equipment. From the indication values the regeneration device forms data signals which change value in synchronism with the indication signals.

Title: A method of and an apparatus for operating a motor vehicle with an internal combustion engine
IPC: F16F15/18
Filed: 1980-04-25
Abstract: A vehicle engine 2 has its flywheel 3 disengageable from the crankshaft by means of a clutch 4. The flywheel is also connectable to the transmission 10 and thus the driving wheels 13 and 14 by the normal clutch 7. When stationary in traffic, the driver can stop the engine 2 after disengaging the clutch 4 by releasing the accelerator pedal 20, leaving the flywheel 3 running. When the driver depresses the pedal 20 to move off, the clutch 4 is re-engaged by a control 18 and the angular momentum of the flywheel restarts the engine. The flywheel speed is maintained above the minimum required for engine restarting either by briefly restarting the engine in response to a signal from a probe 19 monitoring the flywheel speed or by operating a starter motor 15 (which may be replaced by a motor 26 of which the flywheel is the rotor).
