Title: Mecanisme a tension ajustable pour ecouteurs de stethoscope
Inventor: CYBULSKY GEORGE
IPC: A61B7/04
Filed: 2002-07-17
Abstract: Un mécanisme à tension ajustable pour écouteurs de stéthoscope allongés comprend un collier, une partie de mécanisme de pivotement pour chaque écouteur, entre la partie proximale de l'écouteur et le collier, une partie de mécanisme à ressort entre la partie proximale de l'écouteur et le collier, et un mécanisme de réglage de tension entre la partie ressort et le collier. Pour chaque écouteur, le mécanisme de pivotement définit un axe de pivotement autour duquel pivote l'écouteur, et la partie de mécanisme à ressort comprend une lame souple se déformant lors de l'écartement des écouteurs. Cette déformation produit une tension des écouteurs s'opposant à tout écartement ultérieur. Le mécanisme de réglage de tension définit plusieurs points de contact interchangeables avec les lames souples, lesdits points de contact ayant des positions différentes par rapport au collier.

Abstract: A process for producing coke from a combined feed.          The combined feed is initially provided as a first portion which comprises easily cokable components and a second portion which is essentially free of easily cokable components.  The first portion is heated to a temperature lower than that normally employed by a coking heater in a delayed coking process.  The second portion is heated to a temperature at which a combination of the first and second portion provides combined feed at coking temperatures.  The combined feed is then subjected to coking conditions.  The first portion, in one embodiment, may be comprised of a fresh feed (10") and the second portion may be comprised of a coker recycle.  In another alternative, a fresh feed (10') and a coker recycle are combined and fractionated to produce the first portion and the second portion.  The first portion may include components which boil above a temperature of about 482°C, and the second portion may be essentially free of easily cokable components.

Inventor: BERG EILERT J
IPC: G07D5/08
Filed: 1990-10-09
Abstract: An electronic coin chute (ECC) for use in a public telephone station has only a small amount of electrical power available from the telephone line when examining coins for authenticity and denomination. To conserve power during the examination process, a plurality of coin quality sensors are used, each designed to use minimum power. Each sensor generates an oscillating magnetic field that interacts with the coin as it gravitates through the coin chute. By monitoring the output electrical signal from each coin quality sensor, the microprocessor is able to determine when the coin has moved beyond its field and, in response, power is removed from that sensor and applied to the next. After the coin's qualities have been measured, they are compared with stored acceptance limits. Power is removedfrom the last coin quality sensor and applied to a coin routing apparatus to guide acceptable coins into a collection box.

Filed: 1990-11-22
Abstract: In radio communication equipment for use in a mobile station, provision is made for selectively applying either one of the oscillation outputs of first and second local oscillators to a transmitting part and a receiving part by first and second RF switches, respectively.  In a traffic channel hand-off system for a mobile communication system in which each time the mobile station moves from a certain zone to another, its traffic channel is switched to another traffic channel of a different frequency, a control part responds to a traffic channel assigning signal from the current base station to allot an idle one of the local oscillators to the assigned channel, set the allotted local oscillator to an oscillation frequency corresponding to the assigned channel, and control the second RF switch, in an idle time of the receiving part in the current communication, to set the receiving part to the assigned channel for receiving a down link hand-off preparatory signal from a new base station.  Further, the control part controls the first RF switch, in an idle time of the transmitting part in the current communication, to set the transmitting part to the assigned channel for transmitting an up link hand-off preparatory signal to the new base station. These preparatory procedures are followed by controlling the first and second RF switches to supply the oscillation output of the allotted local oscillator to the transmitting part and the receiving part, thereby completing the traffic channel hand-off without momentarily interrupting the communication.
