Abstract: A pump actuating system is associated with a container having a pump for dispensing the container contents. The system includes a housing mounted on the neck of the container and at the same time the housing serves to couple the pump with the outlet end of the container. The pump is of the reciprocal type having a reciprocating plunger which also serves to direct the container contents away from the pump. A conduit couples with the pump outlet and serves to direct the pumped container contents either coaxially with or transversely of the axis of the neck of the container in accordance with the selected dispensing pattern. An actuator is mounted by the housing and is coupled with the conduit for facilitating the actuation of the pump between a first pump position at which the container contents are drawn into the pump chamber and a second position at which the contents are expelled therefrom. The actuator is integrally molded so as to include a trigger, toggle and guides.

Abstract: A dispenser carton capable of being formed from a single-piece paperboard blank is disclosed. The blank is suitable for erection into a rigid, rectangular container having a measuring chamber therein which is provided with a "locked-in", slide-valve discharge opening at the dispensing end of the chamber which is reclosable.

Abstract: This invention relates to an endless track having chain links which are connected by connectors as well as rod members extending through the connectors.A connection between the connectors and rods is provided by clamping contact surfaces on the rods and connectors in abutment with other, at least one of said contact surfaces comprising at least one depression arranged around the circumferential area of the bolt or connector contact surface, whereby a friction lock preventing the bolts from moving axially and/or rotating with respect to the connectors is achieved.

Abstract: A replaceable cartridge for a dispenser comprises an elongated collapsible envelope for containing the material to be dispensed. The cartridge includes a tubular body portion and two end walls which are of one-piece with the tubular body portion. The cartridge is constituted by a thin-walled, flexible, limp and collapsible material. A cap portion having a discharge outlet faces one end wall of the cartridge, and a movable compression disc faces the other end wall of the cartridge. In response to movement of the disc, the cartridge is collapsed to thereby cause rupture of the end wall adjacent the discharge outlet. Alternatively, a puncture needle is provided on the cap portion for puncturing the end wall adjacent the discharge outlet. Once opened, the material within the cartridge is free to escape through the discharge outlet in response to such movement of the disc.

Abstract: Disclosed is a fluid dispensing system for dispensing fluid from a container under pressure. An automatically variable restrictor is disposed in the fluid line between the container and the faucet whereby a constant predetermined flow rate is provided at the faucet. In one form hereof, the containers are serially connected one to the other with the restrictor placed between the last container and the faucet. In another form hereof, series/parallel arrangements are provided wherein sets of serially connected containers are coupled in parallel one to the other with the last container of each set being fluid connected to the common faucet. A restrictor is placed in each set of serially connected containers between the last container and the parallel connection with the faucet whereby a constant flow rate through each parallel connected set of containers is obtained and equal to the number of sets of parallel connected containers divided by the desired flow rate through the common faucet.

Abstract: Metering valve employs resilient ball to block inlet while outlet port is open. Inlet seat includes projections which assure unseating of the ball when the valve actuator is released.

Abstract: A scraping apparatus is provided for a track-type vehicle which has a track with a chain and shoes. The scraping apparatus has first and second scraping elements each having first and second opposed cutting edges. The first scraping element removes foreign material from the chain and the second scraping element removes foreign material from the shoes. The scraping apparatus removes foreign material during forward and rearward movement of the track.

Abstract: A pneumatic spacer and cushioning tire assembly, having an armored peripheral track fitted thereto is provided for use on construction and earthworking equipment. The track assembly has a belt of elastomer insulated inextensible filaments constrained between anchor plates and traction plates. The interior surface of the track assembly prevents movement between the track and the tire.

Abstract: The invention pertains to an automotive tractor unit, more particularly for riding and working on vertical walls and ceilings, of the type which consists mainly of a frame; of belt shaped progression elements or tracks which are appropriately driven and are provided with adhesion devices such as suction discs or magnets as well as with elements for attaching appropriate accessories or tools such as a spraying piston or suchlike to the tractor. The belts or tracks are fitted so as to hinge with respect to the frame and around shafts which extend in the longitudinal sense of the tractor.

Abstract: A container for separate storage includes a receptacle for a liquid product, a retaining sleeve having a detachable capsule integrally molded therewith to be separated by tearing of a rupturable wall portion joining the capsule and sleeve for releasing an additional product in the capsule into the liquid product as the capsule falls into the receptacle, and a stopper including a dispensing spout.The stopper is fixed to the retaining sleeve for conjoint rotation around the receptacle neck, and the capsule and the receptacle neck have interengageable reliefs to hold the capsule against rotation whereby twisting the stopper will rotate the sleeve to tear the rupturable wall portion, releasing the capsule.Mixing of the two products may be assisted by the user shaking the container, and the ensuing mixture may be dispensed through the stopper spout.

Abstract: The head portion of a railway car coupler is provided with forwardly projecting horizontal upper and lower shelves. The leading edge of the top shelf is angled upwardly and rearwardly to provide clearance for coupler droop. Additionally, the leading angle of the coupler can be extended upwardly to establish an improved relation between the leading edges of the mating couplers, thereby minimizing the tendency to have one leading edge slipping under the other during a droop condition of the couplers.

Abstract: An endless track for a tractor or the like comprises a pair of laterally spaced link assemblies attached to a plurality of track shoes. In a first embodiment of this invention, a single stiffener extends laterally across each track shoe and is releasably attached to a pair of laterally spaced links of the link assemblies and to one of the track shoes by common bolts. In a second embodiment, a pair of stiffeners are each releasably secured to one of the links and to the track shoe.

Abstract: An endless track assembly comprises a pair of laterally spaced link assemblies each having a plurality of articulated links. Each pair of interconnected links is mounted on the end of a pin having a torsional track bushing mounted thereon. The torsional track bushing includes a metallic sleeve spaced longitudinally from one of the links and an elastomeric-based bushing secured between the metallic sleeve and such link for permitting relative torsional movements therebetween. The elastomeric-based bushing may constitute an annular member entirely composed of an elastomer, an elastomeric member secured on a metallic ring, or a plurality of elastomeric discs interleaved between a plurality of metallic discs.

Abstract: An alcoholic beverage, or other fluid, dispenser which uses to advantage the electrical pulsing of an electric pump which, for each pulse, dispenses a discrete fluid volume, to thereby provide as a selected volume of dispensed fluid the sum of said discrete volumes. Among other advantages, variation in the volume of the dispensed fluid is readily achieved by simply correspondingly varying the number of pulses permitted to be transmitted to the pump.
