A pressing apparatus for producing a food service paperboard container from a paperboard blank so that the paperboard container possesses an overturned rim provided with folds includes a first die and a second die that are movable relative to one another. The first die includes a first base and a first platform that is movable with respect to the first base, with the first base having a curved surface for engaging the outer periphery of the paperboard blank. The second die is positioned in oppos...

An apparatus is used to form a container from a blank which has innermost fold lines that confine a closed bottom of the container, and outer fold lines that extend outwardly from four corners of the bottom. The apparatus includes a blank forming device which defines a forming passage of polygonal cross-section and having four corners. A blank feeding device is adapted to feed the blank towards the blank forming device in a first direction substantially parallel to the cross-section of the formi...

Apparatus for forming boxes or box covers, the apparatus having feeding means and forming means that are both driven by a common driving means, the forming means being operable in a reciprocating, substantially arcuate motion to impart vertical motion to box blanks or box cover blanks prior to operation of the forming means on the blanks.

A radar system is disclosed for obtaining data to map planets employing and S-band ranging transponder (RT) that is widely separated from and in motion relative to a stationary transmitter-receiver station (STRS) on earth. The STRS transmits a ranging signal which is biphase modulated by a pseudonoise (PN) code, and the RT retransmits the PN-modulated signal on a different carrier frequency. The STRS receives the retransmitted signal as a reflected signal from an area of the planet (AP) being ma...

A box forming machine comprises a pair of box forming dies and a double-ended ram which engages and inserts a blank into one die, and on its withdrawing movement from that die inserts a blank into the other die. The blank is initially stored in a substantially vertical stack and moved from that stack to a conveyor during which time a part of the blank is folded. The blank is then positively delivered to the die by means also effective to maintain the folded part of the blank in its folded condit...

An apparatus having a male mold, a female mold and plurality of fingers suspended about the male mold for controlling a sheet of material being formed into a flower pot or flower pot cover. The female mold has a female opening defining a female forming surface. The male mold, in turn, has an outer periphery defining a male forming surface which mates with the female forming surface. The fingers are adapted to telescope in relation to the male mold. With a sheet of material over the female openin...

The signal lamp is for use in cafes, night club tables, restaurant tables, cocktail lounges and other locations for the purpose of signalling a waiter when service is desired. The lamp includes a grill-type sleeve frictionally slidable upon an illuminated holder and movable to an upper or a lower position on said holder. The sleeve has an opaque band which stops illumination and indicates when the sleeve is raised that service is desired.

A vertical carton erecting machine of the stationary die-reciprocal plunger type in which the knife edges for opening the carton slots and receiving the tabs are fixedly mounted on the plunger. Cam-operated flippers press the top edges of the carton outwardly to cause the tabs and slots to interlock. Carton strippers stationarily mounted at the bottom of the die may then engage the carton and strip it from the plunger as the latter is withdrawn.

A tray in tray container of corrugated board material is formed from a pair of pre-formed flat body blanks in a bi-level machine having vertically aligned upper and lower dies in which a mandrel reciprocates vertically. The inner body blanks and outer body blanks are stacked in feed hoppers adjacent the upper and lower dies, respectively, and individually stripped out of their respective hoppers into horizontally disposed positions over their respective dies, substantially simultaneously. The fe...

A flat-paneled flower pot or flower pot cover and apparatus and method for forming a sheet of material into a flat-paneled flower pot or flower pot cover. A platform supports a female die having an opening with flat surfaces for forming panels in the base and skirt of the flower pot or flower pot cover. The sheet of material is centered over the opening of the female die. A bracket having a plurality of legs which align with the panel-forming surfaces of the female die is placed on the sheet of ...
