Title: Method for capturing an end head onto a press platen in a roll wrapping unit and assembly for implementation of the method
Inventor: OHTONEN AIMO
IPC: B65B25/14
Filed: 1990-10-31
Granted: 2001-01-30
Abstract: The present invention concerns a method and assembly for the capture of an outer end head (4) onto a press platen (1) in roll wrapping unit. According to the method, the outer end head (4) is taken with the help of a clamp (2) close to the press platen (1) and a rapid air flow is injected into the gap between the platen (1) and the end head (4). This air flow effects an underpressure into the gap between the end head (4) and the press platen (1), whereby the end head (4) is forced by the effect of the ambient pressure close to the press platen (1). As soon as the end head (4) is close to the platen (1), a vacuum applied via suction holes (25) in the platen (1) sucks the end head (4) against the platen (1). The assembly in accordance with the invention applies the air flow via a channel (18, 23, 24) arranged to pass through the press platen (1) into the gap between the press platen (1) and the end head (4).

Title: Telephone subscriber line voltage change detection
Inventor: PEPPER DAVID A
IPC: H04B3/46
Filed: 1990-12-19
Granted: 1995-02-14
Abstract: TELEPHONE SUBSCRIBER LINE VOLTAGE CHANGE DETECTION     Abstract of the Disclosure Changes in a telephone subscriber line voltage are detected in a telephone set by supplying a voltage dependent upon the subscriber line voltage to a potential divider having first, second, and third tapping points, the second tapping point being between the first and third tapping points, and comparing the voltages at the first and third tapping points with a smoothed version of the voltage at the second tapping point to produce pulses at respective terminals when the line voltage is falling or rising. An algorithm is described for responding to the pulses to distinguish changes in hook state of another telephone connected to the same subscriber line from interfering signals. The arrangement facilitates remote release from hold and privacy indication functions for the telephone set.
Patent CA-2034036-C (CA)
Title: Detonation transfer apparatus for initiating detonation of an insensitive detonating cord utilizing an initiating compound, flyer and shock reflector
Inventor: BARKER JAMES M
IPC: F42D1/04
Filed: 1991-01-11
Granted: 1995-05-23
Abstract: An improved detonation transfer apparatus is set forth. In one embodiment, it incorporates a transverse bulkhead having selected explosive materials on both sides thereof. The bulkhead is shaped into a concave lens to focus the shock wave toward a focal point so that one of the explosive materials directs a shock wave into the other of the explosive materials, thereby triggering sufficient shock wave pressure for detonation. In an alternate embodiment, a blasting cap transfers detonation to a first secondary explosive material which forms a flyer; the flyer travels across the space, impacting with a metal transverse bulkhead which in turn transfers a shock wave through the bulkhead into another explosive shaped in the form of a pellet. This has a high impedance reflector plate in it. The reflector plate is approximately parallel to the transverse bulkhead so that shock wave reflection occurs at the plate and further increases shock wave pressure, thereby exceeding the levels necessary for detonation, and detonation is thereby transferred into the detonating cord.

Title: Charging circuits for rechargeable batteries and cells
Inventor: NOR JIRI K
IPC: H02J7/00
Filed: 1991-03-13
Granted: 1996-10-22
Abstract: Circuits are provided whereby rechargeable batteries and cells are charged very fast by a controlled current, and substantially at a rate never exceeding the ability of the battery or cell to accept current--i.e.: to convertelectrical current to stored chemical energy. The resistance free terminal voltage of the battery or cell is detected during an interval when the charging current is interrupted, and compared against an independent reference voltage to control the charging current when a difference between the reference voltage and the sensed resistance free terminal voltage exists. The reference voltage may be altered at any instant in time, as a function of the ambient temperature, or the internal temperature or pressure of the battery, as a function of the charging current when it is within a predetermined range, or if a particular change in the value of the charging current occurs over a predetermined period of time. Charging characteristics may also be controlled and altered either through the passage of time or as a consequence of predetermined conditions occurring. The various provisions preclude thermal runaway for example, and assure very rapid and complete charging operations no matter what may be the condition of the battery--provided it is capable of accepting charge--and for various kinds of rechargeable batteries and cells including nickel cadmium, lead acid, and so on.

Title: Apparatus and process for producing kettle-style chips
Inventor: HENSON WILLIAM DOUGLAS
IPC: A23L5/10
Filed: 1991-05-15
Granted: 1996-10-01
Abstract: Potato chips having hardbite texture and flavor characteristics of kettle-fried potato chips are produced in an apparatus comprising a fry kettle with cooking oil circulation and heat transfer means. Production efficiency is greatly increased over conventional batch preparation of kettle-style chips; batch size is significantly increased and total fry time is advantageously decreased.  In certain embodiments the batchwise preparation process includes the step of selecting texture-setting potato slice dehydration rate conditions for at least a segment of the frying time, which ends before the moisture content of the slices is reduced to about 45% by weight or less.  Selecting appropriate dehydration rate conditions enables the production of potato chips of a variety of textural characteristics over varying cooking oil time/temperature profiles.  After introducing a batch of potato slices into a kettle of frying oil, the potato slices are fried during the texture-setting time segment while controlling the frying to achieve the selected dehydration rate conditions.  After the texture-setting time segment, the moisture content of the slices is further reduced by continuing to fry the slices in the oil to achieve a moisture content in the slices of about 2% by weight or less.  Temperature may be controlled via a programmable control system.

Granted: 1999-02-16
Abstract: A data transfer system including an exchange, wherein the exchange transfers data by sharing a plurality of channels by a time division multiplex mode. In this case, the exchange transfers the data by variably allocating to the channels channel lengths to be occupied by the same. That is, it is possible to allot any line speed to any channel and therefore possible to mix signals with different data transfer speeds in the frames. This results in an exchange network with a high degree of freedom of transfer for the subscriber terminal equipment.

Title: Plasma cycling sterilizing process
Inventor: MOULTON KERN A
IPC: H05H1/46
Filed: 1991-08-09
Granted: 2002-02-19
Abstract: A method for plasma sterilization within a controlled temperature range comprising exposing an article in a sterilizing chamber (4) to a gas plasma flowing from a plasma generating chamber (2) until the temperature in the sterilizing chamber (4) rises to a preselected maximum temperature. The flow of the plasma gas to the sterilizing chamber (4) is terminated until the tem-perature in the sterilizing chamber (4) falls to a temperature below the preselected maximum temperature. These steps are repeat-ed until sterilization of the article is effected. The temperature below the preselected maximum temperature when gas plasma flow is again initiated is preferably not more than 3°C below the preselected maximum temperature. The gas plasma can be generated from a mixture of gases consisting essentially of argon, helium, nitrogen or mixtures thereof. Preferably the pressure in the steri-lizing chamber (4) rises to from 0.1 to 10 torr when the gas plasma is flowing into the chamber (4) and the pressure in the steriliz-ing chamber (4) falls to a lower pressure whan the gas plasma flow into the sterilizing chamber (4) is terminated.
