A removable link brace includes a fixed member (38) and a removable member (40) having a lever member (42) and a link engaging member (46). A carriage (50) is supported by wheels (58) on tracks (54 and 56) which are substantially parallel to the plane of motion of the links and includes a plurality of rollers (60) which are substantially parallel to the tracks.

Abstract: Food frying apparatus is disclosed which provides apparatus which may be easily and safely operated to prepare small portions of various food products. The food frying apparatus includes an upright cabinet with a fan assembly mounted in the upper-most portion of the cabinet to exhaust air through the top of the cabinet while drawing air in, through and from the lower portion of the cabinet. A removable one-piece filter unit is positioned in the path of air flow to remove odors, gases, smoke, etc. from the air before the air is exhausted back into the room. The removable filter includes a paper filter together with activated charcoal particles configured as an integral unit. A container for holding a supply of cooking oil is located in the lower portion of the cabinet and is positioned in an insulative shroud with a resulting decrease in BTU's required to operate the apparatus. The heater element is embedded in the bottom portion of the container and does not directly contact the cooking oil.

Abstract: A method and apparatus for attaching mounting plates (12 and 14) to a workpiece such as a strut (16) is disclosed. First and second conveyors (34 and 36) carry the mounting plates with the workpiece positioned above them past first and second rollers (40 and 42) respectively. The rollers have ribs which form circumferential grooves aligned to allow passage of rows of prongs (18) while the ribs extend sufficiently close to the conveyors to make contact with the workpiece and to force rows of holes 24 in the workpiece down over the prongs.

Abstract: A carriage for a trimming device for grass, weeds and the like having at least two runners (20 and 22), a grip (24) for gripping a handle pole (26) of the trimming device and holders (28 and 30) affixed to the grip for holding the runners in a spaced apart relationship for supporting the device is disclosed. Opposing grip members (33 and 35) form a channel (42) for receiving the handle pole and two cross channels (34 and 36) for holding the runner holders.

Abstract: Disclosed is a bypass valve interconnect system for connecting two lumens of a multi-lumen catheter to a single transducer for alternately measuring and recording fluid pressure in each lumen. The system includes a three-way stopcock valve interposed in each lumen output line and interconnected through a bypass line.

Abstract: A mud logging system for receiving and displaying conditions measured during the drilling of a well includes a plurality of units for receiving and processing signals from sensors responsive to the values of the conditions. A/D convertors in each of said units produce digital representations of signals received from the sensors and the digital representations are utilized with visual display means in the units for digitally displaying values of the conditions. A slave computer of the digital type is interfaced with the A/D converters and a file disk. Under control of said slave computer the digital representatives are transferred to the file disk, and a recorder also under control of the slave computer displays selected ones of the conditions. The system also includes a master computer of the digital type connected to access data on the file disk, to utilize the accessed data to provide for analysis of drilling conditions.

Abstract: Automatic food frying and dispensing apparatus is disclosed which is housed in a supporting cabinet and includes a device for holding a supply of cooking oil and a heating device for maintaining the temperature of the cooking oil at a predetermined temperature. A fan assembly exhausts air through the top of the cabinet. A derated precipitator, a flame arrester and a charcoal filter are positioned upstream of the fan assembly and in the path of air flow. A switch device is positioned in the path of air flow and shuts off the heating device if the air flow drops below a predetermined value. Food handling apparatus automatically lowers the food to be cooked into the cooking oil when a customer selects a desired cooking time and automatically raises the food from the cooking oil and dumps the food into a container positioned at the food collection station at the end of the preselected cooking time.

Abstract: Briefly, in this invention, a reversing device comprises a rotational wheel or other device in contact with one face of the curtain, which is caused to rotate upon descent of the curtain, and imparts a series of impulses each of which recommences a timing sequence of a timer at normal descent rate, but upon reduction of descent speed (caused for example by an obstruction), the timer times out its entire period and actuates a timer switch and relay circuit which reverses the motor to raise the curtain.
