Title: Phyllosilicate containing aminoplast wear layer for resilient surface coverings
Inventor: FERNANDO RAYMOND H
IPC: B32B27/40
Filed: 1992-01-02
Abstract: SURFACE COVERING                          Abstract The flexibility of aminoplast wear layers is improved by the addition of a phyllosilicate.  The con-centration of the phyllosilicate is sufficiently low to not adversely affect other physical properties of the wear layer.  The reduction or elimination of urethane improves stain resistance.  The gloss level obtained for a given concentration of phyllosilicate depends on the particle size, and therefore type of phyllosilicate, as well as amount of phyllosilicate.  A surface covering having areas of different gloss level can be obtained by printing areas forming the wear layer with compositions containing different types of phyllosilicates.

Title: Survival seismic detection system having improved tunable filter
Inventor: HARMELING JAY S
IPC: G01V1/00
Filed: 1992-02-24
Abstract: 56,035 ABSTRACT OF THE DISCLOSURE A survival detection system distinguishes a low frequency survivor generated signal component from ambient low frequency signal components in a seismic sensor signal output.  A twin-tee filter circuit a has its input coupled to the sensor signal output and it has a plurality of interconnected charging resistor and capacitor components with an output circuit coupled thereto to generate the detected survivor signal component.  A CMOS switch is connected in each charging current path between the associated resistor and capacitor in such path to control the capacitor charging currents.  A bandwidth control circuit applies an adjustable feedback voltage from filter output circuit to the twin-tee filter.  A variable duty cycle generator controls the on-off duty cycle of the CMOS switches to control the effective charging current path resistance and thereby the capacitor charging currents and the tuned or center frequency of the filter.  The variable duty cycle generator includes an oscillator having a relatively high frequency output applied to a comparator against a floating variable voltage reference.  Variation of the voltage reference produces a comparator output with  variable on-off cycling which accordingly operates as a duty cycle control for the CMOS switches and ultimately as filter frequency control.

Title: Travel board game
Inventor: WILLIAMS LORRELL E
IPC: A63F3/04
Filed: 1992-04-22
Abstract: ABSTRACT OF THE DISCLOSURE    A board game comprises a travel board provided with spaced indicia representing stations and line indicia representing travel routes between stations; a set of questions related to a station or other locale depicted upon the board, and dice for use to select one of several alternative modes of transport between stations.   The line indicia preferably represent alternative travel routes corresponding to the different modes of transport to be used.  Preferably, for interest in playing the game, the alternative travel routes present different degrees of difficulty in reaching the next station.  This difficulty may be determined by the number  of  stopping positions  being different  along alternative routes so as to affect the time taken for travel via that route.   Each stopping position may be correlated with a particular set of questions, for example by colour coding or symbols.  The travel board may represent a geographical area with the stations representing geographical locations within that area.  The questions may be general knowledge questions, perhaps on a particular topic or topics related to the geographical area.   At least one specific geographical location is a finish location at termination of travel.  In this case, it may be determined that play has not ceased until a potential winner has answered a question of the set associated with the finish location.  The geographical area may be shown as a map of,  for example,  a country or a continent.

Filed: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE            A  squeeze  pack  comprises  an  elastically  deformable  external container and an internal container arranged therein for accommodating the filling material. The internal container is divided into first and second  portions  in  the  middle region  of  its  longitudinal  extent, substantially transversely to its longitudinal axis.
