Title: Cylinder lock with a cylinder housing and a cylinder core, as well as a key
IPC: E05B27/06
Filed: 1983-10-08
Abstract: Disclosed are cylinder lock arrangements which include a rotatable cylinder plug provided with recesses for guiding in axial direction blocking bars which cooperate with the cylinder housing to prevent in a blocking position thereof the rotation of the plug. The blocking bars are formed with blind bores which in a releasing axial position of the bars communicate with a key channel. The blind bores accommodate segmented pin tumblers which are controlled by control recesses on a lateral wall of a key so that upon the insertion of a correct key the separation planes of the segments of the pin tumblers coincide with the separation plane between the blocking bar and the clyinder plug. The key for the lock of this invention has a profile defined by alternating longitudinal ribs and longitudinal grooves whereby the crest regions of the ribs are formed with the control recesses arranged at different levels in accordance with the segments of the pin tumblers.
Patent EP-0113051-A3 (EP)
IPC: G05D3/12
Filed: 1983-11-29
Abstract: An information reading/writing head (H) is positioned to 
follow data tracks (TR) that are formed concentrically on a 
magnetic recording disk (D). A set of spiral radial position-­
indicating markings (P1, P2,..) is formed which can be 
detected on the disk optically, or capacitively. The position of 
the head is determined by sensing the spiral markings. The 
reference for the phase detection is detected by sensing 
radial indicia (R1, R2,..) on the disk periphery or spiral 
markings of servo data with a different pitch and frequency 
from the position-indicating spiral markings. A servo control 
system operated by the above disk, reads the radial position-­
indicating spiral pattern and the reference pattern on the disk 
and compares the relative phases of the two to compute the 
track position of the head. A set of phase-locked loops with 
subsequent phase comparators is used to decode the servo 
data.

Patent EP-0137998-A3 (EP)
IPC: C10G51/02
Filed: 1984-08-29
Abstract: A process for economically converting carbo-metallic 
oils to lighter products. The carbo-metallic oils. contain 
343°C+ (650°F + ) material which is characterized by a 
carbon residue on pyrolysis of at least about 1 and a Nickel 
Equivalents of heavy metals content of at least about 4 parts 
per million. This process comprises flowing the carbo-­
metallic oil together with particulate cracking catalyst 
through a progressive flow type reactor having an elongated 
reaction chamber, which is at least in part vertical or in­
clined, for a predetermined vapor riser residence time in the 
range of about 0.5 to about 10 seconds, at a temperature of 
about 482°C (900°F) to about 760°C (1400°F), and under a 
pressure of about 10 to about 50 pounds per square inch 
absolute sufficient for causing a conversion per pass in the 
range of about 40 to 90% while producing coke in amounts 
in the range of about 6 to about 14% by weight based on 
fresh feed, and laying down coke on the catalyst in amounts 
in the range of about 0.3 to about 3% by weight. The spent, 
coke-laden catalyst from the stream of hydrocarbons form­
ed by vaporized feed and resultant cracking products is 
separated, the sorbed hydrocarbons are stripped from the 
spent catalyst particles by mixing them with hot regenerated 
catalyst particles and passing the mixture through an elon­
gated stripping chamber where desorbed hydrocarbons are 
cracked by regenerated catalyst particles which are 
present. The stripped catalyst is regenerated in one or more 
regeneration beds in one or more regeneration zones by 
burning the coke on the spent catalyst with oxygen. The 
catalyst particles are retained in the regeneration zone or 
zones in contact with the combustion-supporting gas for an 
average total residence time in said zone or zones of about 
5 to about 30 minutes to reduce the level of carbon on the 
catalyst to about 0.25% by weight or less. The regenerated 
catalyst is recycled to the reactor and contacted with fresh 
carbo-metallic oil.

Patent EP-0143561-A3 (EP)
Title: Fiber optic amplifier
IPC: G02B6/26
Filed: 1984-11-02
Abstract: An amplifier for use with fiber optic systems comprises a neodymium YAG crystal (44, Figs. 9, 12, and 13) placed in series with a signal-carrying optical fiber (12b, 54). The ND:YAG crystal (44) is supplied by the optical fiber (12b, 54, 62) with both the signal to be amplified, and pumping illumination. The pumping illumination is coupled onto the optical fiber (12b, 54, 62) by a multiplexing coupler (10b, 50, 60) which is used to combine the signal to be amplified and illumination from a pumping illumination source (42) onto the single optical fiber (12b, 54, 62). The pumping illumination inverts the neodymium ions within the ND:YAG crystal (44). The signal to be amplified propagates through this crystal (44) to stimulate emission of coherent light from the neodymium ions, resulting in amplification of the signal. Because this arrangement permits the ND:YAG crystal (44) to be end- pumped with pumping illumination, and because the length of the ND:YAG crystal (44) may be substantially greater than the absorption length for the crystal (44) at the wavelength of the pumping illumination, virtually all of the pumping illumination may be absorbed within the ND:YAG crystal (44) and used for amplification of the signal carried by the optical fiber (12b, 54, 62).

Patent EP-0173301-A3 (EP)
Title: Sweeper with speed control for brush and vacuum fan
IPC: E01H1/08
Filed: 1985-08-27
Abstract: This invention is concerned with a sweeper, meaning a sweeper with a rotary main brush opposite a hopper, and increasing its ability to load light debris, such as paper, dry leaves and the like so that light debris will be propelled farther into the debris hopper. This is done by setting the speed of the main brush at a lower speed for normal operation to effectively throw what may be thought of as heavier material, such as sand, forwardly into the hopper with the speed being such that excessive wear of the brush is avoided and a higher speed of rotation being effected from time to time so that paper, dry leaves and the like, which may be considered lightweight material, are thrown farther into the hopper with the increased speed of the main brush overcoming the air resistance that normally stops such lightweight material which, at normal operation of the brush, tends to pile up in the rear of the hopper. The sweeper uses a vacuum fan to create a suction in the hopper with the vacuum fan also being speeded up with the brush speed increase which assists in loading the lightweight debris in the hopper. Since the increased speed is used for the main brush and vacuum fan only from time to time when light debris is encountered and on a limited basis, the increased brush wear and power consumption caused thereby is tolerable.
