Abstract: A stored energy ejector mechanism is disclosed and described and includes an ejector plunger member which is propelled by a spring-bias induced by an actuator lever actuated by a stroke of a punch press and the like. The stored energy in these springs is released and the propelling or ejection motion of a plunger member is begun by the actuation of a trigger mechanism whose release time is selectively established and preferably occurs during the same stroke of the press mechanism in which is produced the loading of the springs. Although primarily for use with a punch press to provide a substantially quiet ejector action, this stored energy is equally applicable to other operations such as providing an ejector mechanism for use with a conveying or line inspection system employing linear motion.

Abstract: The present invention pertains to the method for forming vacuum packaged products wherein a tear-inducing tab is provided for easily rupturing the film. This invention is particularly directed toward the wrapping of vacuum packages for packing meat and the like and in which the films used therewith are tough and not amenable to tearing. In this invention is provided a method for forming a flat, substantially inflexible tear tab member having a sharp point. This tear tab is laid on the product to be packaged with the sharp point portion thereof extending therefrom so that after the package has been formed the bending of the seal line of the package at or very near the extending portion of the tear tab causes the point of the tab to puncture the film to permit easy further tearing and eventual uncovering of the product.

Abstract: This invention relates to a vibrating table where a rotary motion vibrator is used to provide vertical oscillations. In this table top arrangement the vibrator is secured to a frame or lower plate member preferably at or about its midpoint. This lower frame member is conventionally supported by a support base through vibration isolators such as coil springs provided at its corners. To at least two edges of this lower frame member are secured transfer pads which also are secured to the like edges of and carry the upper table top a spaced distance above the lower frame. The resulting vertical motion and frequency are equal or substantially equal at all portions of the table top and there is an absence of "dead spots." Conventional table tops of vibrating tables to which the vibrator is directly secured have a dead spot or spots and the amplitude is unequal causing the material or product thereon to walk or move to one side.

Abstract: This invention pertains to a hair curler having a roller rotatably mounted on end supports whose base portions are adapted to rest on the head of the user. Each end support operates independently of the other and one or both includes a self-contained securing tension mechanism in the form of a ratchet device. This ratchet device in no way restricts the winding of hair around the roller portion of the curler assembly. After a section of hair has been wound around the roller, the base of the rotatable end support is positioned on the head and the roller remains in this condition with the end support sustaining the curler while retaining the hair wound thereon until the desired drying, styling or curling effect of the hair has been achieved. The base of the end support is constructed in such a proportioned manner that the support retains and restricts movement of the hair roller from the prescribed and seated position on the user's head.

Abstract: This invention pertains to an air-actuated vibrator of the turbine-type in which the rotor and enclosing chamber is contoured so as to provide within the normal operating range a low noise level which is below 80 db (hertz). In association with this chamber is a novel muffler which receives the output from the chamber and reduces the noise level to about 65 db or less which is much below the tolerance level established as acceptable. The rotor is the only moving part in this vibrator and has its periphery formed with small tooth-like transverse serrations but other similar profiles may be used. The tooth profile is of such small size that the driven rotor which is peripherally driven by pressurized air within a normal supply range produces noise levels which are sufficiently low so that the operation of the vibrator in combination with the associated muffler is considered to be virtually silent.

Abstract: This invention pertains to a segmented expanding sleeve for an expanding mandrel or chuck in which air or hydraulic fluid is fed to and into a resilient tube or tubes arranged in a longitudinal or in a helical manner. This tube or these tubes are carried by and in grooves formed in the body and when pressurized air or fluid is fed into the tube means the tube or tubes are expanded in a controlled manner to outwardly move a plurality of like-linked leaf members or segments. Each leaf member has one longitudinal edge formed with a keyhole-type groove and the other edge of each leaf is formed with a tongue member having an enlarged outer portion. In an assembled condition the tongue member of one leaf is mounted in the keyhole groove of the next adjacent leaf and these tongue and groove arrangements provide an outer limit to the expansion. Resilient inner tying members extend between leaf members and retain and draw the leaf members into an inner limit against the body of the chuck.

Abstract: This invention pertains to a pet feeding device for cats, dogs and the like. The feeder base retains a feeding dish or tray. A timing device opens the cover of the feeding dish or tray at a preselected time. The tray is removably secured to a floor or wall and a hinged cover is actuated by tension springs providing means for opening the device to uncover a dish by a timing mechanism. This mechanism is selectively set by the owner or attendant to provide the animal with food or water, or both, at a determined time period, for example, eight or twelve hours. The cover and base are provided with a seal and preferably are insulated so that the moisture in the pet food or the aroma of the food cannot escape. Insulation also insures that the pet food does not spoil during the time it is stored within the timed release feeding device prior to its being released and made available for the feeding of the animal.

Abstract: This invention pertains to tooth transmission members in which the tooth member is mounted to a support member and the tooth or pocket is used to drive or be driven by roller chains and the like. A base member is provided and is usually a form blank such as a disc or length of metal to which is secured assembled preforms in a linked array. Each preform provides a roller receiving tooth profile. The linked preforms are tightly retained on the previously prepared base members. Any selected number of preforms may be used and at least one is secured to the support blank upon which they are mounted. The support blank may be regularly or irregularly shaped depending upon the desired resulting transmission member.

Abstract: This invention pertains to turbine-type vibrators in which the rotor member has the blade portions arranged in an annular pattern. The blades extend substantially at right angles to the plane of rotation of the rotor. The blades are carried on and extend from the side of the rotor and may have one or two parallel rows. When two rows of blades are provided one row is arranged on each side of the rotor and a divider is preferably provided between the blades. Each annular grouping has its own inlet and its own outlet.
