Patent EP-0470971-A1 (EP)
Title: Recording and/or playback device for contactlessly scannable rotating recording substrates.
Inventor: KUEHN HANS ROBERT
IPC: G11B19/22
Filed: 1990-04-23
Abstract: Such playback devices, e.g. CD players, are fitted with a loading and release mechanism for the recording substrate, the CD. However, before a CD is released from the CD player after playback or the pressing of a 'STOP' button, it must be stopped to prevent damage to its sensitive surface. Because the mass and diameter of CDs varies and there are also mini-CDs, the CD may still be rotating during the release process. To prevent damage during the release process, the CD is safely and rapidly brought to a standstill by generating the necessary braking force dependently upon the rotation speed of the CD. CD players, video disc players, magneto-optical devices, DRAW disc players.

Abstract: The dry electric shaver (10) includes a pair of movable cutter blocks (31) reciprocatively movable by a drive bar (15) with respect to a fixed perforated comb (25). The cutter blocks (31) are coupled to the drive bar (15) by a unitary one-piece plastic cutter support (40) having a central body (41) engageable with the drive bar (15) and having coaxial torsion bars (48,49) extending from the opposite sides thereof, the distal ends of the torsion bars (48,49) being respectively integral with the midpoints of elongated arms (50,51) disposed substantially perpendicular to the torsion bars (48,49). Each arm carries (50,51) at each of its ends an attachment portion (54) having an opening (55,56) receiving a stake (37) on the cutter block (31) in press-fitted engagement. The cutter support (40) is sufficiently resilient and flexible to accommodate varied movements of the cutter blocks independently of each other, while remaining relatively stiff in the direction of movement of the drive bar (15). A bias spring (60) urges the cutter support (40) and the supported cutter blocks (31) toward shearing engagement with the comb (25).

Abstract: A 31-bit addressing scheme is disclosed which is compatible with current 24-bit addressing schemes and allows an address space of 2GB to be created. The shared area of the operating system is divided into two separate areas (230, 260), one (230) located at the bottom of the address space and the other (260) at the top of the address space. Between the shared areas (230, 260), a continuous private area (240, 270) is available for use by the applications software. In one embodiment of the invention, the size of the bottom shared area (230) is limited to 1MB blocks so optimising the use of private area (230) by applications programs written for 24-bit addressing.

Abstract: A PLL circuit is operatively coupled to a power source and comprises a phase comparator (2, 3) for comparing phases of an input signal and a feedback signal, a memory (7, 8) for storing information related to the input signal, a control voltage output circuit (15) for outputting a control voltage based on the information read out from the memory, and a feedback loop circuit (4, 5, 10) including a voltage controlled oscillator (5) whose oscillation frequency is controlled by the control voltage received from the control voltage output circuit. The feedback loop circuit supplies a signal which is derived from an output signal of the voltage controlled oscillator to the phase comparator as the feedback signal. The use of the memory means (7, 8) allows the PLL circuit to lock to a target frequency within a short time regardless of the time constant of the feedback loop.

Abstract: A device and a process are useful for monitoring the hardness and elasticity of the stringing of raquets for ball games such as tennis, squash or badminton, with high resolution of the results, which are therefore very accurate and of high reproducibility. The hardness and elasticity of the stringing are measured in parallel or consecutively in a measurement procedure. Until the actual monitoring measurement begins, any existing irregularities in the stringing or irregularities due to other external factors are eliminated by self-adjustment of the device. The monitoring measurement values are obtained by determining the resilience of the stringing produced by tension or pressure. This is transferred to a measurement part where it is evaluated electronically. The result can be read on a display.

Abstract: On applique un laser (1) au côté d'une voie d'écoulement traversée par un milieu. Le faisceau lumineux provenant du laser (1) traverse la voie d'écoulement. Les particules (5) à l'intérieur du volume de mesure du milieu sont heurtées par la lumière et le défléchissent, ce qui forme des cônes lumineux dirigés vers l'avant. Ces cônes lumieux sont réfractés à l'extérieur de la voie d'écoulement par une lentille (6) et heurtent ensuite une plaque de détection (8). La lumière qui heurte la plaque de détection (8) a la forme d'anneaux lumineux créés par la diffraction. Au moins deux anneaux détecteurs sont disposés sur la plaque de détection (8), lesdits anneaux étant constitués d'éléments photosensibles aptes à mesurer la puissance lumineuse des anneaux lumineux qui les atteignent. Une unité de différentiation électronique (9) crée une différence entre les valeurs mesurées de la puissance lumineuse de deux de ces anneaux détecteurs. On obtient ainsi un signal de différence qui peut s'associer à la distribution granulométrique des particules qui se trouvent dans le milieu en écoulement.

Inventor: ENSMINGER WILLIAM D
IPC: A61M25/00
Filed: 1991-03-01
Abstract: An infusion port designed for the introduction of a catheter for fluid infusion or removal or other flexible filaments within a patient. The infusion port is buried subcutaneously and accessed using a needle which introduces the filament. The infusion port has means to prevent the introducing needle from being inserted past a certain point within the port whereas the introduced flexible element can be inserted beyond that point and is caused to be forced through an articulating valve. The valve of this disclosure features enhancements in its sealing ability and in some embodiments provides a differing level of frictional engagement with the filament upon insertion versus withdrawal. The infusion port of this invention also has design features which provide a relatively small distance between the surface of the skin and the position of the articulating catheter valve through which the introduced filament passes.
