Title: Field-mounted control unit
Inventor: WARRIOR JOGESH
IPC: H04B3/50
Filed: 1990-10-01
Abstract: A smart field-mounted control unit, for controlling a process, receives signals and sends a command output over a two-wire circuit which powers the control unit. An input section receives the signals, which can be instructions representative of commands or instruction sets, process variables sensed by external control units or setpoints representative of a desired process state. The instructions are representative of a control requirement of the process and adjust a controlling section in the control unit to generate the command output in conformance with the control requirement. The command output can be a function of the difference between the process setpoint and a process variable, or a function of a linear combination of a process variable and its calculated time integral and time derivative functions. A sensing section in the control unit can sense and scale a process variable for generating the command output as well. The control unit can include a regulator section, controlled by the command output, which regulates application of a mechanical, hydraulic, pneumatic or electromagnetic force applied to the process.

Abstract: The invention relates to low delivery cigarettes, usually having a mainstream particulate matter delivery of about 9mg or less.     The cigarettes(1) comprise a rod (2)  of tobacco material and a filter element (3).  The filter element (3) comprises an alkali filter material section (4) having a loading level of less than 12% by weight of the section.  The characteristics of the  cigarettes  (1)  are  arranged  so  that,  when  smoked,  the alkaline  filter material  is  exposed  to an  amount  of  smoke acceptable to achieve an increased perception of smoke impact.     This is usually achieved by using a low particulate matter potential rod.   In this way the moisture free dry particulate matter  (NFDPM)  to nicotine ratio is decreased compared with control cigarettes having the same cigarette characteristics without the addition of alkaline filter material to the filter element.

Patent CA-2075000-A1 (CA)
Title: Home brewer
IPC: A47J31/56
Filed: 1992-07-30
Abstract: A beverage brewing apparatus which employs a water control assembly, a moisture recovery assembly, an improved thermostatic and low water sensor configuration and an easily removable sprayhead.  The control assembly controllably regulates the flow of water from the fill basin into the reservoir using a valve which is interconnected with a lid covering a fill opening in the hood portion.  Water from the basin will not flow into the reservoir, and thus will not produce a brewed beverage, until the lid is closed by the user.  The moisture recovery assembly employs a baffle opening and a collection portion on a vent to return condensation which may accumulate on the vent to the fill basin.  A sleeve is positioned in the fill water opening in the hood portion to collect condensation and to reduce the surface area of the water which may be affected by air movements through the brewing apparatus.  The thermostatic and low water sensing configurations position the temperature sensors outside of the water heating reservoir to prevent the accumulation of mineral and other deposits thereon.  A portion of the wall behind which the sensors are positioned is thinned in order to more accurately read the corresponding temperatures.

Title: Switching step observation system
Inventor: GARVER CLARENCE E
IPC: B60R1/00
Filed: 1993-01-28
Abstract: SWITCHING STEP OBSERVATION SYSTEM    Abstract of the Disclosure A switching step observation system allows an operator in the operator station of a train locomotive having a full width nose cab to observe any activity on and around the switching steps at the front of the locomotive, even though the full width nose cab obscures the direct view of the switching steps.  The system provides a small secondary mirror which is visible in the large rear view mirror which is standard equipment already present adjacent to the operator station. This small secondary mirror is mounted in such a position that it reflects an image of the switching steps to the operator by way of the large rear view mirror.  Preferably, the small secondary mirror is mounted to be adjustable about two axes, so that the operator can easily adjust the mirror to obtain the optimum view.  If switching steps and a rear view mirror are present on both sides of the locomotive, the system may be duplicated on both sides of the locomotive, so an operator can see both sets of switching steps from one position.

Patent CA-2090415-A1 (CA)
Title: Self-reinitializing padding device
Inventor: DREW TERRENCE M
IPC: A43B21/28
Filed: 1991-08-27
Abstract: A self-reinitializing padding device (10) having at least two fluidly connected chambers (40, 50) which contain flowable material for use in applications where it is desirable to reinitialize the padding device (10) for subsequent use in absorbing and/or distributing impact forces. One application for which the padding device (10) is particularly well suited is as a foot padding device (10) in footwear. The impact force of the user's foot deforms a primary chamber (40), thereby forcing some of the flowable material contained therein to flow into a plurality of secondary chambers (50). The rate of deformation of the primary chamber (40) exceeds the flow rate into the secondary chamber (50), thereby providing a cushioning effect. When the portion of the footwear coinciding with the primary chamber (40) loses contact with the ground, the force is removed from the primary chamber (40), thereby allowing the secondary chamber (50) to contract and force some of the flowable materials contained therein back into the primary chamber (40) to reinitialize the padding device (10).
