Title: Remote control traffic system
Inventor: MURPHY DAVID W
IPC: G08C17/00
Filed: 1991-08-28
Abstract: Remote Control Traffic System Abstract of the Disclosure A remotely controllable traffic control system adapted for controlling traffic in two directions from opposite ends of a control area includes first and second portable sign structures adapted for placement at the ends of the control area. Each sign structure includes a transmitter/receiver device and a changeable sign having at least two traffic control positions including a stop position and a proceed position. A single operator control remotely positionable from the sign structures controls both the sign structures. Circuitry presents both signals from providing a simultaneous proceed indication. Upon loss of power for any reason at either sign, the affected sign will automatically revert to stop. The transmitter can be programmed for a large number of signals to eliminate the problem of spurious activation of either sign. A single operator controls both signs to reduce the possibility that the two signs will give conflicting signals (i.e., two proceed signals in a one-way control zone).

Abstract: MIXER APPARATUS      Abstract A miser for liquids and liquid suspensions has a motor drive and housing which is portable and can be carried from tank to tank and attached to the tank where mixing is carried out.  The housing depends from the yoke and contains a quill which is driven by the motor drive.  A chuck mechanism is associated with the housing and quill to enable mixer impeller shafts to be held in assembled relationship in the mixer and readily removed and replaced with shafts having impellers specially adapted for the particular mixing application of interest.  The chuck mechanism is operable even though the quill is hidden in the mixer housing.  A latch is pivotly mounted on the outside of the quill and has a tab which extends into the quill.  The tab latches on to a rim of the mixer shaft when the shaft is inserted into the quill and received in driving relationship with the motor drive, as in a drive socket floatingly supported at the upper end of the quill.  The latch is held by a spring suitably provided by a expansible lock ring so as to enable the latch to pivot as a lever about a fulcrum which contacts the quill along the base surface of a slot in which the latch is retained by the expansible ring.  The latch provides temporary support for the shaft.  The shaft is locked in the quill by a manually actuable connector (suitably a set screw) which is disposed in alignment with the latch in order to align the quill with an opening for a tool which is manually actuable to lock the shaft in place with the set screw. An indicator surface is provided on the latch facing an indicator which is mounted in the housing.  The indicator is preferably flexurally mounted in an opening in the housing so as to enable it to be used as a button to pivot the latch in order to release the mixer shaft. The indicator may be a bi-stable magnetic indicator with a moveable member having a magnet at the end thereof facing the quill surface at the opposite end thereof for providing an indication of alignment:, when the magnet thereon is repelled by a magnet providing the indicator surface of the latch.  The indicator may be a body of optically transmissive material which makes the indicator surface visible through an end thereof outside of the housing.  The indicator may alternatively be a tactile indicator which has a surface configuration complimentary to that of the indicator surface on the latch so that the operator can feel when the indicator surface on the latch comes into alignment therewith.

Abstract: To:   Commissioner of Patents Consumer and Corporate Affairs Canada 50 Victoria street Place du Portage, Phase I Hull, Quebec, K1A 0C9 FORMAL APPLICATION FOR PATENT            ABSTRACT:   There is always the release of some odeur during the fish cooking process, especially when one tries to frying fish. In a confined space or in the kitchen of inadequate ventilation, the fish odeur is more noticable. In this invention, fish obtained in the market either in the form of fresh or frozen was treated with a solution (described in specification section); and then cooked in the normal ways such as frying, steaming, baking... This odeur was eliminated between 85-95% compared with the control (untreated fish). Rating wasdone based on frying fish since by frying, very strong odeur was released from untreated fish.          The advantages of this invention can be listed as: - With 5-15% of odeur is still released from fish tissue during cooking (treatedfish), odeur is not strong enough to embedded in clothing or body of the cook. - Taste of treated fish is better and more crispy than the one untreated. - The eaters do not feel a fish smell in their mouth after eating treated fish.
