Abstract: A cross arm unit for supporting wires such as in a grapevine supporting trellis. The cross arm unit has an elongated arm member which is secured to a socket member transversely related to the arm member. The end portions of the arm member are reverse curled with the ends being spaced from the remainder of the arm member to provide wire-passing slots. In one form of the invention the socket member is of square cross section with the arm member bisecting the passageway of the socket member so as to form a stop facilitating frictional mounting of the cross arm unit of the top of a post. When the post is of standard metal construction, the socket member will be arranged so that the arm member crosses its passageway diagonally. When the cross arm unit is intended for mounting on a wooden stake, the socket member will be arranged so that the cross arm member is normal to one set of side faces of the socket member but parallel to the other set.

Abstract: In a rotary fan (10) having a tubular drive shaft (14) and a lower cylindrical hub (16), an isolator bushing (20) interconnects the drive shaft (14) and hub (16) so as to substantially reduce vibrations. The bushing (20) is elastomeric, tapered and mounted within the hub (16) in an uncompressed state to maintain vibration-reducing properties. The drive shaft (14) extends into and terminates within a central bore (42) of the bushing (20), and the end portion of the shaft (14) is secured at a lower portion of the bushing (20). The hub (16) is secured to an upper end surface of the bushing (20) and the length of the bushing (20) provides dampening of vibrations caused by rotary motion. The tapering of the bushing (20), while maintained in an uncompressed state, provides dampening of vibrations caused by resonant frequency characteristics.

Abstract: A pocket ventilation roll baffle assembly adapted for use in drying a paper web is disclosed. The pocket ventilation roll includes a stationary tubular inner core roll, a tubular outer shell roll mounted for rotation in concentrically spaced relation about the inner core roll, and a device for supplying drying air within the inner core roll. The drying air flows longitudinally through the inner core roll and radially outwardly through an arcuate portion of longitudinally arranged perforations contained in the inner core roll and circumferential perforations contained in the outer shell roll. The pocket ventilation roll baffle assembly includes a baffle arrangement for adjusting the profile of the drying air flowing radially outwardly from the pocket ventilation roll.

Abstract: A take-up assembly for storing and selectively feeding and taking up flexible line, usually hydraulic hoses, extending between the body or mast of a lift truck and the vertically-reciprocating load carriage of the truck. The take-up assembly includes disassembly features for facilitating servicing of the take-up assembly and flexible lines while mounted on the truck and further includes external seal features for protecting its internal fluid seal structure from contamination and thereby improving its durability without permitting such external seals to add substantial rotational drag to the take-up assembly.

Abstract: A push-pull slipsheet handler mountable on a standard hook-type lift truck carriage compatibly with load-handling forks mounted on the carriage. The slipsheet handler comprises a push-pull assembly and split platen, both of which receive their vertical support from the load-supporting surfaces of the forks. Attachment of the push-pull assembly to the lower hook-type bar of the carriage provides resistance against fore-and-aft movement of the slipsheet handler. To convert the truck rapidly to a fork-type truck capable of handling standard rigid pallets rather than slipsheets, the platen may be quickly removed leaving the push-pull assembly in place or, alternatively, the push-pull assembly and platen may be removed as an integral unit.

Abstract: Improved spin-bonding apparatus is disclosed for connecting a synthetic plastic end closure member to a composite container body wall, including an axially displaceable spinner member that is operable to an axially extended position in which it is rotated relative to the stationary mandrel by the rotatably driven spindle when the mandrel and spindle are in an initial axially spaced condition. The spinner member continuously supports the inner periphery of the sealing fin as the mandrel and spindle are displaced axially together toward their adjacent spin-bonding condition, whereby the sealing fin is protectively supported prior to positive spin bonding thereof to the synthetic plastic inner liner of the container body wall. The stationary mandrel is provided at its free end with a unitary sizing portion having a closely toleranced cylindrical surface for causing the free extremity of the container body wall to have a circular configuration.

Abstract: A lift truck load clamp, for handling cylindrical loads such as paper rolls, having an automatically adjustable load positioner extending between the clamp arms which moves forwardly in response to closure of the clamp arms and rearwardly in response to opening thereof to assist the lift truck operator in positioning the clamp arms with respect to rolls of different diameters such that the contact pads of the clamp arms automatically grip such differently-sized rolls in diametrically-opposed relation. The load positioner is particularly adapted for use with clamps wherein both clamp arms are movable with respect to a clamp frame, because each end of the positioner is separately movable forwardly or rearwardly with respect to the frame in response to movement of the respective adjacent clamp arm.

Abstract: A method and apparatus are disclosed for forming a novel corrugated paperboard web of indefinite length, which web includes a planar facer layer and a corrugated layer the flutes of which extend longitudinally the length of the web. The web is formed by splicing together sections having offset planar facer and corrugated layers of generally equal dimensions, respectively, whereby at one end the facer layer projects beyond the corrugated layer and at the other end the corrugated layer projects beyond the facer layer, the flutes of the corrugated layer extending from one projecting end to the other. Successive sections are spliced together with the projecting facer layer portion of one section overlying the projecting corrugated portion and the facing layer of another section, preferably with the adjacent portions of the corrugated layers of the two sections being in flute-enmeshing engagement.

Abstract: A lift truck rotatable paper roll handling clamp of the pivoted arm type for clamping paper rolls of varying diameters and shifting the position of the roll relative to the lift truck between a position of unequal extension, wherein the forward end of one clamp arm extends a greater distance forwardly than the forward end of the other clamp arm, and a position of equal extension wherein the forward ends of the clamp arms extend a substantially equal distance forwardly of the lift truck. The clamp has a rotatable frame upon which a subframe is mounted by a first pivotal connection for selective tilting of the subframe relative to the rotatable frame. Mounted upon the subframe are a pair of clamp arms, each being pivotally connected to the subframe at spaced pivotal connections located on either side of the first pivotal connection. One clamp arm is longer than the other, and pivots with respect to the subframe through a greater maximum angle than does the other arm.

The container includes a vertically arranged body member that is flared at its upper end, and an end closure member is provided including a circular central panel portion arranged within and extending across the upper end of the body member, annular chuck wall portion extending upwardly from the central panel portion adjacent the flared portion of the body member, and an annular connecting flange portion extending radially outwardly from the upper end of the chuck wall portion. The invention is characterized in that the connecting flange and chuck wall portions cooperate with the flared portion of the body member to define an annular space in which is arranged a resilient annular mass of sealing material.

Abstract: A laminated wooden structural assembly is disclosed comprising at least one multi-ply wooden web member formed of a pair of spaced outer layers and at least one inner core layer bonded between the outer layers, and at least one wooden flange member arranged adjacent one longitudinal edge portion of the web member. The web and flange members are connected by joint means including a straight machine tapered longitudinal slot contained in one surface of the flange member, and a machine tapered longitudinal edge portion of the web member that is inserted with a friction fit into the slot. Each inner core layer of the web member is arranged with its grain direction extending toward the longitudinal edge portion of the web member, the outer layers being arranged with their grain directions extending parallel to the flange member. The flange member is arranged with its grain direction extending in a direction longitudinally and parallel with the grain direction of said web outer layers.

Abstract: A composite container is disclosed having a synthetic plastic end closure member spin-bonded to the thermoplastic synthetic plastic inner liner layer of a composite container body wall. The synthetic plastic end closure member includes annular downwardly depending inner fin and outer chime portions which are concentrically spaced to define therebetween an annular groove. One of the body and end members is rotated relative to the other member when they are in spaced vertical alignment, whereupon the members are axially displaced together to wedge the upper end of the body member into the annular groove of the end closure member. During this spin bonding process, the fin portion of the end closure member is supported against radial inward deflection, whereby the spinning frictional engagement between the fin portion of the end closure member and the inner liner layer of the body member causes softening and subsequent bonding of the fin portion to the inner liner layer.

Abstract: A side shifter having a quick-mounting anchor bracket for mounting on a conventional hook-type lift truck carriage without the need for welding of any side shifter components, such as a hydraulic ram anchor, to the lift truck carriage. The side shifter features alternative upper and lower hydraulic ram anchors and interlocking relatively movable components which are prevented from disassembly when the side shifter is detached from the lift truck carriage. Friction-reducing bushings for accommodating the transverse sliding motion of the side shifter are engaged with the quick-mounting anchor bracket in such a way so as to prevent not only transverse motion but also upward motion of the bushings which might otherwise occur under the influence of the load moment. The side shifter features lower hook assemblies capable of supporting the side shifter at an elevated position when detached from the lift truck carriage, and capable of exceptionally fine vertical adjustment.

Abstract: A controlled stop circuitry which frees the operator for carrying out other duties of cycle-interrupt time, by being automatically operable, when once activated, to partially raise the electrodes and to open the transformer switch, but only after the electrode current has decreased to a safe value. More particularly, the circuitry when actuated in a designated manner, interrupts an operating cycle by raising the electrodes, while simultaneously sensing the current supplied to them, and is effective, when the current decreases to a safe level, to automatically open the transformer switch and stop movement of the electrodes in partially raised positions. The circuitry also permits, as an option to the above procedure, the carrying out of the above steps, except that it delays opening of the transformer switch until the electrodes reach the top of their travel.

Abstract: The appliance includes a casing 10 in which is mounted a connection 13 for a container 12 of pressurized liquid carbon dioxide.
