Title: Drive unit for transport trolley
Inventor: MAKIMURA KATSUYOSHI
IPC: B65G35/06
Filed: 1993-05-18
Granted: 1996-06-11
Abstract: The present invention intends to prevent generation of metallic noise when both longitudinal sides of the chain supporting trolley (22) installed to the center link (19) of the chain collide against the ends of the adjoining side links  (20a,  20b,  25) when the driving chains  (18) which comprise linkchains in which a center link (19) whose plane shape is an elongated ring and a pair of top and bottom side links  (20a,  20b,  25) are linked alternately become loose.          The present invention comprises a rib (32) installed to the center link (19)  at the longitudinal center,  vertically notched grooves (27c, 28c, 33), in which the rib (32) of the center link is fitted,  provided to the vertical portion (27a,  28a)  penetrating the center link  (19)  of a pair of left and right trolley units  (27,  28) composing the chain supporting trolley (22) and to a plate type spacer  (29) which intervenes between both vertical portions (27a, 28a) and is made of plastics,  and a portion of both front and rear sides of the said plate shape spacer  (29),  which at least adjoins the ends of the side links  (20a,  20b,  25), protruded longitudinally outward from the vertical portion (27a, 28a) of each trolley unit.

Title: Synchronised electronic identification system
Inventor: MARSH MICHAEL JOHN CAMILLE
IPC: H04B1/59
Filed: 1993-08-25
Granted: 2004-11-23
Abstract: The invention relates to an identification system comprising an interrogator and a plurality of transponders. The interrogator includes transmitter means for transmitting an interrogation signal to the transponder, receiver means for receiving a response signal from the transponder, and processor means for identifying the transponder from data in the response signal. Clock extraction means are further provided for extracting a transponder clock signal from the response signal which is used to synchronise the modification of the interrogation signal with the response signal from the transponder. Each transponder comprises receiver means for receiving the interrogation signal, a transponder clock generator, a code generator, transmitter means, and a modulator connected to the node generator, so that on receipt of the interrogation signal the transponder transmits a response signal containing data which identifies the transponder. The interrogator is adapted to detect successful reception of a response signal from any transponder, to derive a synchronisation signal from the response signal of that transponder, and to modify the interrogation signal synchronously with the response signal to indicate successful reception of the response signal. Each transponder further includes means responsive to a respective modification of the interrogation signal to cease transmission of its response signal.

Granted: 2003-12-09
Abstract: A floor box wiring fitting incorporating a novel carpet flange possessing a self-closing flap cover assembly, whereby the fitting is adapted to be cast into a concrete floor of a building for the conductance of electrical power or telecommunication signals between the work spaces of buildings. The self-closing action of the flap covers which are hingedly connected to the flap cover plate structure, the latter of which consists of a carpet flange, is essentially implemented through an angular operative contacting relationship between the wall surfaces of the openings receiving the hinging portion of the flap covers and the contiguous or adjacent wall surface of the flap cover which, in effect, will inhibit the flap covers from being opened or swing upwardly from a closed horizontal position to an acute opening angle greater than about 85°. This acute maximum opening angle measured from the horizontal upper surface of the carpet flange will cause the flap covers to be downwardly closed, in the absence of any plug connectors or receptacles being inserted through the carpet flange, under the action of their own weight or gravity. Also included is novel structure for staking hinge connections of the flap covers in place, and structure for latchingly engaging the flap covers in their closed positions.

Granted: 1998-09-22
Abstract: The present invention prevents damage to the trolling motor and the mount by providing a shock-absorption system capable of lengthening to allow the motorassembly to pivot out of the path of an obstruction.  Adjustable friction force maintains the clutch system assembly in its normal operating upright condition. When the trolling motor strikes an underwater object, the clutch friction is overcome and the clutch assembly lengthens, thus assuring that any damage is minimized.

Title: Sealing system, security seal and injection moulding system for manufacturing a sealing system
Inventor: DE LIMA CASTRO NETTO EDUARDO
IPC: B65D55/06
Filed: 1993-03-30
Granted: 2002-10-01
Abstract: A sealing system of the type in which a locking pin is received in a cavity containing a tooth that cooperates with the pin to prevent withdrawal of the pin. The object of the invention is to provide this type of seal but which is at the same time both of high security and simple to manufacture. In the system of the invention, the cavity (2) has two openings (14, 16) adjacent to each other and separated by the base (17) of the tooth (18). The cavity is otherwise totally closed and its inner wall (21), which extends to the bottom of the cavity, is curved under the base (17) of the tooth. This permits manufacture using an injection mould having a plate (39) provided with a fixed part (40) and a part (41) rotatably mounted on the fixed part to define therebetween the male mould portion for moulding a cavity with a tooth. An actuator (42) serves to rotate the rotary part (41) during opening of the mould, the rotary part (41) having a curved surface (52) corresponding to the curved part of the inner wall (21) of the cavity.  Security seals and devices incorporating the new sealing system are also described.

Patent CA-2145372-C (CA)
Inventor: HANSCH EGON
IPC: B65H29/06
Filed: 1995-03-23
Granted: 2003-05-06
Abstract: The conveying device exhibits a plurality of clamps which are each articulated, via a carrying arm and a linking member, on rotational elements. The pivot position of the carrying arm is controlled by a first slotted-guide path and, separately from this, the position of the linking member is controlled by a second slotted-guide path. This permits pivoting of the clamps even independently of the movement of the carrying arms. The clamps can thus be controlled in an optimum manner for the respective purpose. In particular, it is possible, with constant speed of the rotational elements, to change the speed of the clamps and, at the same time, to control the direction of the clamps independently.

Granted: 2000-02-22
Abstract: For detecting the presence of a substance such as ice or snow on a surface such as the wing of an aircraft, light is emitted from an unpolarized source (13). The unpolarized light passes through a linear polarizer (11) which has a vertical polarization axis. The vertically polarized light passes through a quarter wave retarder plate (12), which changes the linearly polarized light into circularly polarized light. The quarter wave retarder plate (12) has its slow and fast axes both at 45 degrees relative to the vertical axis of the linear polarizer (11). A specular surface (14) reflects the incident circularly polarized light back along path (23). If surface (14) is ice-free, the reflected light will result in an image viewed by the eye (26) alternating between dark and bright, respectively. Any ice or snow covering a portion of surface (14) will cause that portion of the image to maintain the same brightness.
