Abstract: Bottle capsules (1), shrinkable onto a bottle neck, are produced by blow molding. An extruded plastic tube (2), in a thermoelastic state, is introduced into dual molds (3a) tangentially, in vertical motion from top to bottom. Each dual mold (3a) has a constriction (7) which is penetrated by a movably mounted injector (8), for introduction of a blow molding medium. The plastic tube (2) is expanded substantially radially only, and the most severe expansion occurs in the area around the constriction. The molds (3a) are mounted in a turntable (4) driven continuously about a horizontal shaft.

Abstract: To simplify the assembly of filter modules 10, the supporting tube 1 which carries the filter cells 9 is constituted in two pieces. Both the upper tube piece 4 and the lower tube piece 5 contain locking elements 7 which are received in correspondingly large recesses 8, thereby making possible a safe interlock as well as a relative axial movability of the tube pieces 4 and 5.

Abstract: In a method for making objects of foamed, thermoplastic synthetic substance, air pressure is maintained in the mold while it and the contained plastic particles are heated, said air pressure being equal to or slightly higher than the pressure of the steam used for heating. When the mold has reached the saturated steam temperature, the air pressure is reduced to fuse the prefoamed synthetic particles together. Thereafter steam is introduced to displace the air in the mold and heat the synthetic particles to the temperature required for fusing or sintering.

Abstract: A dispenser construction having a tubular fitment member with an open end, and a stopper member having an annular wall and a side opening therein. The stopper member has a discharge passage communicating with the side opening and a discharge orifice at the end of the discharge passage. The stopper member is carried in the open end of the fitment member, and is axially movable thereon between a raised, discharge position, and a lowered, sealing position. Sealing structures are provided on the open end of the fitment member and on the annular wall of the stopper member, and disposed above the location of the side opening thereof, to prevent leakage of liquid.

Abstract: A weldless and solderless fluid distribution piping system incorporating solely mechanical retention of one or more inlet/outlet fittings in holes in the side wall of a pipe. In each case, the fitting has at one end a fishmouth configuration and an annular bead, and this end end is first inserted into the hole in the pipe and the bead thereafter forcibly expanded into tight mechanical and sealing relationship with the edges of the hole. A deformable and resilient sealing gasket can optionally be interposed between the fitting and pipe to provide an improved seal, if desired. Novel apparati and a method for attaching such fittings to a pipe are also disclosed.

Abstract: A push-to-open, non-resealable cap construction for hand-held dispensers. The cap has a body member with a discharge passage, and a nozzle member carried by the body member and axially shiftable thereon between a raised, sealing position and a lowered, discharge position. There is a discharge orifice in the nozzle member. A valve structure on the members controls communication between the discharge passage and the discharge orifice to regulate product flow. A blocking rib on the nozzle member normally maintains it in the raised, sealing position in the absence of an external axial force, but the rib can be re-positioned by turning the nozzle member, which latter can then be shifted from its raised, sealing position to its lowered, discharge position. A detent structure on the body member and nozzle member thereafter serves to retain the latter in its lowered, discharge position once it has arrived there.

Abstract: A valving-type closure having a resilient diaphragm provided with a portion having a through slit for the passage of fluids, the slit portion being adapted to bulge and open the slit in response to fluid pressure applied to one side thereof. The slit portion has abuttable, cooperable structures on one side, which come into forcible abutment and act to physically open the slit as the portion bulges. Preferably the abuttable structures are in the form of rings molded on the underside of the diaphragm. The slit through the diaphragm also extends through the ring, thereby forming two semi-circular ring segments. The ring segments in turn form abutment shoulders that pivot the walls of the slit away from one another when the diaphragm is bulged, thereby resulting in a more pronounced spreading force being applied to the walls, and increasing the size of the opening formed by the slit.

Abstract: A safety circuit arrangement for use with lifting/tilting devices for emptying garbage containers into garbage trucks. To prevent the manipulation of switches such as flap and acknowledgement signal switches provided on such lifting/tilting devices, for the safety of the operating personnel, these switches are connected to a current flow monitor 25 which is electrically connected to an automatic control unit 30 for the automatic emptying of the garbage containers. This current flow monitor 25 transmits a "clear" signal to the automatic control unit 30 only if the flap and acknowledgement switches 16 and 11 are in their intended positions. In addition, other safety switches may be provided, such as lower and upper reference switches 9 and 32, respectively and a barrier switch 13.

Abstract: A non-resealable dispenser cap construction having an elongate tapered, stepped hollow spout member with an exterior shoulder intermediate its ends, and a discharge orifice. A closure cap member having a transverse closure wall is mounted on the spout member with the transverse wall engaging and closing over the discharge orifice. With the closure cap member so mounted, the transverse closure wall is distorted and biased by its engagement with the wall of the discharge orifice. One of the members is formed with two oppositely-disposed frangible tabs which overlie and are permanently attached to the other member, and each tab has a zone of weakness which can be readily ruptured upon the application of opposing rotative forces to the members. With the cap member removed the orifice is exposed, permitting discharge of the container contents through the spout member. Re-sealing of the cap member on the spout member is prevented, due to a lack of interengageable parts on the two members.

Abstract: A releasable latch construction having a body member attachable to a panel, a latching member turnable on the body member for arcuate movement between a latching position and a releasing position, a locking mechanism movably carried by the body member and operable to lock the latching member in either its latching position or else in its releasing position, and an actuator movably carried in the body member and engageable with the locking mechanism, for effecting the locking or releasing movement of the latching member. The actuator is directly engageable by a latch key and is shiftable thereby in order to effect such movements.

Abstract: A dispensing cap construction for containers, having a cap body for attachment to a container neck, and having a discharge spout portion through which the container contents can be discharged, and a closure cap turnably carried by the cap body. The closure cap has a non-round or slit-shaped orifice, and a stopper blade in the closure cap is received in the orifice so as to close it off. The stopper blade is rotatably mounted on the spout portion of the cap body to enable it to rotate simultaneously with, or in unison with turning movements of the closure cap. The cross section of the stopper blade is such that it can fit sealingly in the orifice. The cross section of the blade is, in the disclosed embodiment, substantially of rectangular or oblong configuration.

Abstract: A protective shield for a four-in-hand tie which is being worn by a user, comprises a thin, elongate disposable cardboard-like sheet having a width and length which are sufficient to cover the frontal exposed portion of the tie. At one end the sheet has a tab which is adapted to be folded backward and downward so that it can be inserted in the knot of the tie from the top thereof. Intermediate its ends the sheet has fastener portions enabling it to be secured to the frontal portion of the tie so as to position the sheet in front of the tie and prevent any soiling thereof while dining.

Additional removal or discharge elements may be arranged in a row with the working and standing position elements or alternately the removal or discharge devices may be incorporated into the connecting devices.

Abstract: An improved container closure and dosing pump or syringe has a piston formed with a truncated cone-shaped face. A spring-biased operator yieldably holds the piston sealed deeply in a dosing chamber from which it can be shifted to project essentially by the height of the truncated piston face to completely scavenge the chamber. The device is formed of only three injection molded plastic parts and a return spring, to effect inexpensive production.

Abstract: A cover for a trailer hitch, to prevent inadvertent injury to personnel when the hitch is not being used. An upstanding dome is provided for use with hitches of the type having a ball. The dome incircles the ball, and in addition provides a clearance space above the top of the ball, such that the cover can yield when jarred by the knee or leg of a person, thereby preventing injury. The cover has a base which is preferably oversize with respect to the dimensions of the hitch bar, and is provided with internal ribs or other cushinong structures that are yieldable. The ribs engage the surface of the bar such that when the cover is inadvertently bumped, the ribs yield, again preventing injury to the leg of a person. The cover also serves to protect parts of the hitch from corrosion.

Abstract: A membrane type filtering device has modules containing bundles of capillary tubular membranes. To meet various filtration problems the modules have double accesses located at the two end faces of the module housings. Connections to these accesses are made by plugging in the module ends into flow distributor heads, which can be of two types whereby the crossflow can be selectively conducted either through the internal passages of the capillary membranes or else along the outsides of the capillary membranes. Appropriate matching is achieved by exchangeable inserts and exchangeable intermediate tension plates and end tension plates.
