Granted: 2003-08-12
Abstract: A baler for making large cylindrical bales is equipped with a cutting device for cutting picked up crop into pieces before it enters the baling chamber. The cutting device includes a plurality of cutting knives that are pivotable about a horizontal transverse axis between an working position for cutting crop, wherein the knives each project upwardly through respective slits provided in a guide sheet, and a non-working position wherein the knives are withdrawn to a non-working position substantially below the guide sheet. A  plurality of knife positioning elements are respectively associated with the knives and mounted for pivoting about a second horizontal transverse axis such that when the positioning elements are in a first position corresponding to the working position of the knives rollers respectively carried by the positioning elements are in engagement with a recess in a surface provided on the rear of the associated knife. The positioning elements are biased such that the roller carried by a given positioning element will remain in the recess of the associated knife so long as the force tending to rock the knife to its non-working position is below a predetermined amount. Once this force is exceeded, the knife will pivot to its non-working position until the force once again falls below the predetermined amount. A sensing device is associated with a warning or indicator circuit for letting the operator know when one of the knives has moved to a position not occupied by the remaining knives.

Abstract: A television game machine includes a housing. The housing has an air intake and air exit in side surfaces, and forms an air flow passage in a space of air flow on a line connecting between the air intake and the air exit. A heat-radiating member formed with heat-radiating fins is attached in a state electrically insulated from a semiconductor device mounted on the printed board in order to transfer heat generated from the semiconductor device. The heat-radiating member is arranged related to the semiconductor device and printed board such that the heat-radiating fins are along the air flow passage. A heat-radiating fan is arranged between at least one of the air intake and the air exit and one end of the heat-radiating member. The heat-radiating fan, when ambient air is taken through the air intake and caused to flow through the grooves between the heat-radiating fins of the heat-radiating member to be released outside through the air exit, releases the heat dissipated from the heat-radiating fins together with flowing air to an outside. Thus, the heat generated by the semiconductor device is released to the outside of the housing.

Abstract: A restraint device for restraining a vehicle to a loading dock is disclosed.  The restraint device has a pivot member with a hooking member pivotable between an upwards operative position and a downwards inoperative position. The device also has springs for biasing the pivot member in the upwards operative position and an actuator member for bringing back the pivot member from the upwards operative position to the downwards inoperative position. Such a restraint device is securable to a loading dock equipped with a dock leveller which has a platform pivotable between a raised position and a lowered position and a lip. When the platform is in the lowered position, the lip is hanging in a pendant position and engages and presses on the top end of the actuator member thus maintaining the pivot member in the downwards inoperative position. When the platform is pivoted in the raised position in order to proceed with a loading operation of a truck, the lip is caused to move upwards thereby releasing the pressure on the actuator member which causes the pivot member to move in the upwards operative position, therefore hooking the truck to the loading dock.

Abstract: A Network Interface Unit (38, 38', 38") routes incoming calls to, and outgoing calls from, a plurality of telephone sets (12-22) at a subscriber premises (24). The Network Interface Unit continuously monitors for incoming calls and the availability of telephone sets. Upon receipt of a call, the Network Interface Unit determines which telephone sets are idle and applies a distinctive ring to each idle telephone set o identify the telephone line or equivalent on which the call was received. Once a telephone set goes off hook, the Network Interface Unit routes the call to that set and releases the remaining telephone sets for subsequent calls. When a subscriber initiates an outgoing telephone call, the Network Interface Unit detects the call and routes it on an idle outgoing telephone line or equivalent.

Abstract: A test system directed to apparatus for transmitting and receiving multiple telephone transmission signals over a single twisted pair (100). The system converts an analog signal from a local switching (112) station to an 80 ksymbols/sec signal for transmission over a twisted pair by a line card (104). A remote terminal (102) converts the 80 ksymbols/sec signal back into a con-ventional analog signal for use in conventional telephone (108), facsimile or other related equipment. The test equipment separ-ately tests the entire system, the tine card portion of the system, the remote terminal portion of the system, and the twisted pair. An improved 2-to-4-wire hybrid coupling circuit (202) also is disclosed. The improved circuit has 2 extra "wing" coils attached to the known output transformer, the added coils improving the signal strength of the received signal as well as effectively cancelling out feedback from the output amplifier.

Granted: 2005-08-09
Abstract: A free space optical communication system is disclosed whereby the signal amplitude incident upon a receive optical fiber of a receive telescope is varied by dithering either the light beam transmitted by a transmit telescope or the receive optical fiber when a decrease in received signal amplitude is measured so as to effect the incidence of the maximum transmitted signal amplitude upon the receive optical fiber at the receive focal plane. In one embodiment, the transmit optical fiber is dithered in a pattern, causing the transmitted beam to oscillate in a corresponding pattern. In response, the received signal amplitude of the image on the focal plane of the receive telescope also oscillates in the same pattern. By comparing the phase of the received signal with the phase of the movement of the transmitted beam, the origin of the transmitted beam dithering pattern can be moved until the maximum amplitude of the transmitted beam is incident upon the receive optical fiber. In another embodiment, the receive optical fiber is dithered in a variable pattern to locate the point of maximum received signal amplitude.      Using the aforementioned phase comparison technique, the receive optical fiber is moved progressively closer to the point of maximum amplitude of the received signal on the receive focal plane. In cases where atmospheric disturbances alter the path of the transmitted beam, the transmitted beam and the receive optical fiber may both be dithered to achieve coincidence between the point of maximum signal amplitude and the receive optical fiber.

Abstract: A multi-stage diffuser nozzle for use as a drill bit nozzle jet includes a flow restriction portion upstream of a fluidic distributor portion, and also preferably includes a transition region between these two. The flow restrictor communicates with the interior fluid plenum of a drill bit and is used to limit or choke the total flow of drilling fluid by having a relatively small cross-sectional area for fluid flow. The fluidic distributor communicates with the flow restrictor and reduces the exit flow velocities of the drilling fluid as the drilling fluid is ejected from the nozzle by providing a relatively larger cross-sectional area for fluid flow. The fluidic distributor also directs the flow paths of the drilling fluid to advantageous locations such as cone surfaces that are prone to bit balling. The transition region is an area that dampens fluid pressure oscillations in the drilling fluid.
