Abstract: A B S T R A C T         The can opener disclosed comprises a pair of handles which are hinged to one another and which are movable between an open position for fitting onto a can and a closed cutting position. A manually rotatable drive wheel engages the rim of a can and upon rotation advances the opener around a can bringing a knife to a cutting position relative the drive wheel as the handles are brought to the closed position.  The knife is a circular cutting wheel (16) rotatably mounted on one handle (12) with its axis displaced from the axis of hinging.  The other handle (14) has an upstanding cylindrical spigot (26) extending through a corresponding hole (28) in the said one handle (12) and about which the said one handle (12) is hinged relative the said other handle (14).  A support (23)  for the drive wheel (20) passes through and is rotatably born in the spigot (26) with the axis of rotation of the drive wheel (20) displaced from the axis of the spigot (26).   Such a can opener will provide a good clean cut even if the can is damaged.

Abstract: TIMING RECOVERY CIRCUIT            Abstract Prior art circuits for recovering timing information from baseband digital signals include a rectifier and a separate phase detector for controlling the phase of a phase-locked voltage-controlled oscillator.  In the circuit described herein, an antiparallel diode pair is used to perform the two functions of rectification and phase detection.  The resulting timing circuit is, thereby, simplified.

Abstract: Abstract Of The Disclosure In an optical fingerprint image processing apparatus a light beam is scanned across a finger placed against a transparent platen in order to provide a re-flected modulated light beam carrying fingerprint in-formation.  The modulated light beam is imaged and the image is intercepted by an array of photo receptors that detect the image and convert the optical signal into electrical signals.  The improvement is in placing a diffuser element, which may be a ground glass wafer, in the interrogating light beam.  The diffusion of the light beam acts as an effective filter to eliminate the higher spatial frequency components of the optical image and thus provide a fingerprint image having improved continuity.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus  for  recording  an  analog  signal  employs  n rotary heads (where n is a positive integer) which cooperate with a magnetic tape wound around a tape guide drum over an angular range of  .alpha. ° (where    .alpha.° is less than or equal to 360°) and the rotary magnetic heads are rotated at a speed N (where N is greater than one)  times a reference rotation speed.   The input analog signal to be recorded is first converted to a pulse-code-modulated (PCM) data signal which is then time-base compressed by a ratio of (n x  .alpha.°)/(N x 360°) at successive predetermined periods.  The PCM data that has been compressed in time base is recorded on the magnetic tape by the n rotary heads during predetermined intervals that occur within the time when the n rotary heads are in contact with the magnetic tape.   The time-base compression of the data permits the addition of error correction codes and parity words to provide error detection and correction during reproduction of the recorded digital signals and by raising the rotary head speed the number  of memory  units  required  to  perform  the  time-base compression is minimized.

Abstract: DUAL VESSEL HEAT EXCHANGE SYSTEM                  ABSTRACT OF THE DISCLOSURE          A vapor component of a gas mixture is separated by condensation and is recovered for further use.  A solvent vapor mixed with inert gas is condensed in a multistage heat exchange system in a manner which utilizes a first refrigerant to condense a portion of the vapor in a first heat exchange device, a second refrigerant, typically cold inert gas, for condensing a further portion of the vapor in a second heat exchanger and a third heat exchange device wherein chilled liquid is utilized to condense a still further portion of the vapor.  In a fourth heat exchange device, a cryogenic liquid is passed in heat exchange relation with the liquid passed thereto from the third heat exchange device.  The cryogenic liquid is vaporized to form an essentially pure inert gas which is supplied to the vicinity of the oven exit and entrance, but exteriorly of the oven to form inert gas barriers.  The fourth heat exchange device may effect direct or indirect heat exchange with the cryogenic liquid.  By maintaining the vaporized inert gas separate from the inert gas separated from the condensed solvent vapor, a mass balance between gas flows in and out of the oven is readily maintained.

Abstract: ABSTRACT OF THE DISCLOSURE           A varistor fuse element is used for protecting electric circuits against overvoltages and overtemperatures. The fuse element has for electric connection a U-shaped first feed line and a second feed line which is constructed to be elastic, both feed lines being equipped with switching contacts lying opposite to each other.  A varistor is connected, on the one hand, directly to the first feed line and, on the other hand, via a fusible alloy to the second feed line.  In normal operation, the switching contacts are opened and a current flows through the varistor.  When overvoltages occur, the forward current rises steeply in accordance with the I/U characteristic of the varistor.  The varistor is heated by the power dissipation also considerably increasing in the varistor, which leads to the melting-off of the fusible alloy and consequently to the closing of the switching contact. As a result, the electric circuit to be protected is bridged in a low-resistance manner.
