Abstract: A spring pivot joint comprises two face plates with heavy serrations or ribs between them, both sandwiched between Belville springs or spring washers, the washers being held in a strongly stressed condition by a hollow rivet. The face plates have integral wings or tabs extending radially beyond the washers for attachment to the companion mannequin parts to be jointed. Since the rivets are hollow, a simple rod can extend through a plurality of them to hold them in coaxial alignment while being attached to the jointed mannequin parts.

Abstract: A two part molding structure provides a quirk or reveal about a cylindrical column, one part being a spacer ring of flexible material, and the other part being an extruded metal grounding member of simple cross sectional configuration whereby it can be preformed or bent in situ to surround the spacer ring and form therewith the channel or reveal. The grounding member either provides a channel upon which ceiling tile can rest, or an edge against which moldable material, such as plaster, can be applied.

Abstract: A golf head body made as a casting of plastic or metal has a large cavity. A sole plate is attached to close the cavity. The parts are carefully finished by grinding and polishing prior to injection of foamable plastic. The cavity has a special configuration to provide fill holes that are independent of the sole plate. The mechanical strength of the club and installed shaft is not compromised; the foamable plastic, injected after finishing, is not affected by any heat generated by the finishing of the sole plate.

Abstract: An anti-backlash fishing reel comprises a pair of side frames connected by pillars. One of the side frames supports the gear drive mechanisms. A handle projects beyond the side plate or cap attached to that frame. At the other side of the reel, the anti-backlash mechanism is located. A mounting disc or retainer case has its rim clamped to the opposite frame member by a cap or side plate. The mounting disc or retainer case carries magnetic field forming means on its inside for cooperation with a conductive eddy current drum or segment of the line spool. The mounting disc or retainer case also accommodates a bearing for the end of the spool shaft. The spool shaft is extended outwardly of the mounting disc or retainer case to mount a click wheel. Detachment of the cap or side plate allows servicing and cleaning of the magnetic field forming means without disrupting the drive mechanism at the opposite side of the reel.

Abstract: A decapping tool includes a pair of holders, one providing a conical seat for the cartridge head, and the second providing a conical center for the cartridge mouth. The holders are spring urged towards each other whereby the cartridge is held and centered irrespective (within limits) of its length or caliber. A punch rod extends through the center, into the cartridge to the region of the primer cap at the flash hole. An anvil attached to the rear end of the punch rod is engaged by a crank.

Abstract: A golf club head is hollowed out to provide desired light weight characteristics. A tubular reinforcement material formed of plastic including reinforcement fibers, separate from the club head itself, is inserted into the cavity attached at the inner walls of the face and back, so as to span between them to prevent deformation of the head face and to hold the stiffness and mechanical strength required at its impact face.

Abstract: A golf club driver head made from a plastic such as nylon is provided with a sole plate covering a cavity of a predetermined size and depth including a blind bore devoid of any weighting material extending from the inner end of the cavity towards the toe whereby the mass of the head is distributed for dynamic balance.

Abstract: A two part connector with one of said parts providing an elongated cylindrical bore and the other a pin with a flared end, and with an expansible compression ring on the pin urged by a compression spring outwardly of said flared end to grip said bore.

Abstract: A hollow barrel has a shank at one end which connects to the chuck of a machine tool. A simple lamp and lens system at the barrel axis projects an image through the other end of the barrel to the work surface. The work is movable to align a mark or hole on its surface with the projected image, whereupon the work is clamped in place, the barrel removed, and the machine operation performed.

Abstract: One part of the implant comprises a rigid screw anchor of substantially uniform diameter. The anchor has intermediate peripheral threads to engage the bone tissue at a prepared recess. The lower end of the anchor is hollow, peripherally perforated and open at the end to surround a bone core projecting from the bottom of the prepared recess. The upper end of the anchor has a relatively deep wrench socket for rotation of the anchor and for reception of a companion pillar part. The pillar part is made of slightly flexible plastic material that can approximate a prepared tooth to serve as a single tooth replacement or as a support for a fixed bridge. Optionally, the pillar can provide a platform that forms or mounts one of two companion elements of a connector structure such as for overdenture retention. The anchor can be altered in length not only at the bottom, but also at the top, without changing the manner in which the anchor cooperates with the later placed pillar.

Abstract: A plastic valve cartridge for a plumbing fixture can be installed in and removed from a valve casting without tools. One end of a valve cage has detent means that snaps into a cup of the casting. The cage extends across a cavity in the casting so that its other end fits a cylindrical inlet opening. Valve means carried by the cage include a closure having a stem comprising a pair of leaf spring arms releasably snap-fitted to a non-circular hole in a knob or handle. The cage is locked in position by a sleeve that interferes with the detent means of the cage. Key means allow the sleeve to be removed only when the valve is partly open, thus signalling by spout flow the desirability of shutting off the water supply to the fixture before the cartridge is removed.

Abstract: Apparatus and method for selecting, displaying and automatically controlling water flow rates and temperatures at the outlets of devices used in plumbing fixtures such as sinks, bathtubs, showers, or lavatories; the apparatus includes a temperature sensor at the water output, a control panel for selecting desired output water temperatures and flow rates, a comparator for comparing the selected temperature to the output temperature, and for generating signals to control separate hot and cold water valves to achieve and automatically maintain, within limits, any desired combination of flow rate and temperature. In one embodiment the comparator is embodied in a microprocessor which receives a digital signal representative of the actual water temperature, and generates a modified signal to adjust hot and cold water flow to the output means until the actual output temperature matches the selected temperature within a small error range while maintaining flow rate at a constant level.

Abstract: In a water mattress, a series of interior bags or bladders are individually attached to the top and bottom layers in order to damp the movement of water. Each bag or bladder comprises a pair of disks or layers peripherally heat sealed together. Each of the layers of each of the bags or bladders are welded to the respective layers of the waterbed mattress, there being indentations on the inside of the bag or bladder layers, the outside of the mattress layers being substantially free of indentations, there being a bead formed between the welded layers which bead is extruded primarily from the bag or bladder layers.
