Title: Bocadillo de salchicha fabricado con pan de masa moldeada y dispositivo para su fabricación.
Inventor: FILIPPONE CAPLLONCH JOSÉ GUILLERMO
IPC: A23L13/60
Filed: 2017-03-10
Granted: 2018-06-13
Abstract: La presente invención se refiere a un bocadillo de salchicha elaborado con masa moldeada del tipo de las utilizadas para las tortitas de harina o crepes. El nombre que recibe este bocadillo, "panchuque", procede de la combinación de "pancho" y "panqueque" nombres con los que se conoce en algunos países sudamericanos a los perritos calientes y a las crepes.#La masa del panchuque se compone básicamente de harina, agua, mostaza y mantequilla, como lubricante, aunque admite variantes que le doten de otros sabores. La cocción de la masa se produce mediante una plancha específica llamada "panchuquera"; está formada por dos bloques articulados para su apertura y cierre (1, 2), dotados de moldes en cuyas cavidades (3) se vierte la masa y se coloca una salchicha en su interior. Estos moldes confieren a la masa una vez cocida, una geometría similar a la del pan de perrito caliente.

Title: Phase nulling optical gyroscope
Inventor: FABRAS GEORGE A
IPC: G02F1/01
Filed: 1985-12-10
Granted: 1990-08-30
Abstract: A gyroscope system includes a coherent light source that supplies counter propagating wave to a sensing loop through a pair or directional couplers. The polarisations of the waves are controlled so that they traverse identical optical paths before recombining in one of the couplers to form an interference pattern. Rotation of the sensing loop, a phase modulator and a frequency shifter cause phase changes in the counter propagating waves. A detector monitors the interference pattern of the combined waves and provides a signal to a coherent demodulator that controls the phase modulator. The output of the coherent demodulator is input to a servo-loop circuit that drives a voltage controlled oscillator.
