US Patent:
20100031555, Feb 11, 2010
Filed:
Jul 4, 2007
Appl. No.:
12/310501
Inventors:
Gabriel Le Laidier - St. Gellen, CH
Dennis Walstad - Elburn IL, US
International Classification:
A01M 23/24
US Classification:
43 77
Abstract:
An animal trap () for catching voles dwelling in underground tunnels comprises a housing () provided with two openings (). A closing part () which can be moved between a closed position and an open position is mounted in the housing and has a front edge () for applying a, preferably fatal, closing force to a vole, wherein the closing part () can be held in the open position under spring preloading by means of a retaining arrangement. The closing part () can be moved from the closed position into the open position such that on reaching the open position, the closed part () is automatically locked by way of the retaining arrangement, which is operatively connected to the triggering mechanism. When the vole enters the opening, the triggering mechanism activates to trigger the closing movement of the closing part ().

US Patent:
51390515, Aug 18, 1992
Filed:
Jul 1, 1991
Appl. No.:
7/723847
Inventors:
Dennis Walstad - Elburn IL
Jean-Francois Couvreur - Warrenville IL
Assignee:
Furnas Electric Co. - Batavia IL
International Classification:
F16K 130
US Classification:
137630
Abstract:
Start up difficulties in gas compression systems due to undersized motors and/or low voltage conditions are avoided in a system including an electrically operated compressor (10, 36) including a compression chamber (34), a compressed gas reservoir (20) connected to the compression chamber (34) to receive gas therefrom, a pressure control switch (16) associated with the reservoir (20) and operable to control operation of the compressor (10, 36) in response to the pressure level of gas within the reservoir (20), and an unloader valve (42) connected to the compression chamber (34) and operable by the switch (16) by a valve construction including a valve body (50), an inlet (62) to the valve body (50) and in fluid communication with the compression chamber (34), and an outlet (68) from the valve body (50) to the ambient. A relatively large first passage (52) is located in the valve body (50) and extends between the inlet (62) and the outlet (68). A first valve seat (70) is located in the passage (52) and a first relatively large valve member (80) is movable within the passage (52) on the inlet side of the seat (70) and is operable to close against the seat (70).

US Patent:
20140230312, Aug 21, 2014
Filed:
Sep 2, 2011
Appl. No.:
14/342091
Inventors:
Gabriel Le Laidier - St. Gallen, CH
Silvin Jancic - Villmergen, CH
Dennis Walstad - Elburn IL, US
Assignee:
SWISSINNO SOLUTIONS AG - St. Gallen
International Classification:
A01M 23/30
US Classification:
43 82, 43 77, 43 81
Abstract:
The disclosure relates to a snap trap for small animals such as mice or rats, comprising a striking device which can be brought into a striking position and a standby position. The snap trap comprises a housing with a base and with an elongate inner compartment which is open at both longitudinal ends, at one longitudinal end of which an inlet opening leading to an, in particular tunnel-shaped, inlet section of the housing is arranged and at the other longitudinal end of which the striking device is arranged in a striking region of the housing. The disclosure is distinguished by the fact that the striking device is designed for at least partially closing an end opening of the inner compartment in the striking region of the housing and in particular completely closes the opening when the striking device is in the striking position.
