Abstract: An attachment for sewing machines for folding and pressing seam plies for sleeves, trousers and the like having a pair of endless belts or tapes between which the cloth being sewn is carried. After the seam has been sewn, the cloth is carried forwardly into the path of a V-shaped seam opening member which causes the seam plies to be separated, be positioned at right angle to the cloth and lie on either side of the seam in a common plane. Upon being carried further forwardly, the seam plies engages a seam folding member which guides and folds over the seam plies from their right angle position to a flattened position against the cloth whereby the seam plies lie in substantially the same plane as the two layers of cloth after which the heated rollers and a hot air blower presses the four layers of cloth in superimposed contact relation.

Each of the bands being provided with a metal loop at one end and a Velcro fastening strap at the other end whereby the bands rimly engage the wrist and forearm of the user while playing tennis to provide relief to the user having tennis elbow as well as preventing the user from developing tennis elbow.

Abstract: Panel attached guides for tub enclosures and the like having an inclined and unobstructed combined water return and track for sliding panels, the guides having a slotted portion for receiving the lower edge portion of a panel with fastening means for securing the guides to the panel and a second slotted portion for slidably receiving a ledge on the track to permit the sliding movement of the panels in side by side relation. The guides mounted on the panel that is further removed from the ledge than the other panel being provided with a web portion joining the slotted portion of such a width to permit the other panel to slide along the track without obstructing the sliding movement of the further removed panel.

Abstract: A lockable cover for push button telephones to prevent the unauthorized making of outgoing telephone calls consisting of a base member attachable to the underside of the telephone and a cover member having a raised portion to cover the push buttons of the telephone. The base member and cover members are pivotally secured together at the front edges thereof with tabs on the rear edges that have aligned openings for receiving a lock. When the lockable cover is in place on the telephone, the push buttons cannot be actuated to make unauthorized outgoing phone calls.

Abstract: A hygienic device having a plate that is adapted to be mounted on a wall and the like with fittings thereon connected to a source of hot and cold water with a valve for adjusting the amount of hot water to be mixed with the cold water; the mixture then flowing through a fitting mounted on the plate having a slide valve that is normally closed but is opened upon inserting a quick coupler device therein. The quick coupler is provided with a receptacle for containing a medicine and a venturi into which the medicine is permitted to mix with the water that is then discharged through a douche nozzle.

Abstract: An inhalation device for encapsulated concentrates having a capsule piercing hypodermic needle, a mouthpiece and a cavity for receiving a capsule containing a granular medicant and the like, whereby the device is actuated to pierce the capsule to form a pair of aligned openings. An aerosol bottle is so mounted on the device that fluid under pressure is conducted through the hypodermic needle and through the aligned openings in the capsule to disperse particles of the medicant thereby. The mixture of fluid under pressure and particles of medicant are then discharged through a venturi passageway in the mouthpiece and into a person's mouth.

Abstract: A mosquito trap consisting of a receptacle containing water and having two chambers separated by a screen member. The first chamber is open to the atmosphere while the second chamber is enclosed and contains a food retaining member remote from the first chamber. The mosquito trap permits a female mosquito to lay its eggs in the water of the first chamber. The ensuing larvae will swim through the screen member to the second chamber in quest for the food. Upon growing larger and transforming into a pupa stage and then into a young adult mosquito, they become trapped to die in the second chamber as the screen openings are not of such size to permit the larvae, pupae or mosquitoes to escape back into the first open chamber.

Abstract: Parasail launching and retrieving apparatus adapted to be mounted on a vehicle such as a boat having a tower for supporting a rotatable and pivoted main boom and outrigger boom. The outrigger boom supports the parachute when not in flight and the main boom has a line extending along its full length, one end being connected to a powered winch and the other end having a harness for supporting a person desiring to engage in the sport of parasailing. Upon the person being connected to the harness and the boat moving forwardly at a sufficient speed to permit the billowing of the parachute, the line is payed out and the parachute becomes airborne carrying the parasailor. When it is time to retrieve the parachute the winch is energized to reel in the line as the boat speed is progressively decreased until the parachute is in close proximity to the boat. Then the outrigger boom is extended to engage the canopy of the parachute while the person is deposited in the boat and he is then unhooked from the harness.

Abstract: A metering valve device being particularly adapted for the precision control of metering minute quantities of fluids and the like from a high pressure environment to a low pressure environment, even to a vacuum. The metering valve device having a cylindrical core and an inlet and an outlet. The inlet is connected to a radially disposed duct that extends to and forms an opening on the surface of the core, while the outlet is connected to a V-shaped slot positioned on the surface of the core in space relation to the opening. A sleeve that is slidably mounted on the core has a portion that forms a leakproof chamber between the core and the sleeve at the position of the opening and a seal-tight engagement of the core at the position of the V-shaped slot. Upon sliding the sleeve so as to permit a desired part of the V-shaped slot to be brought within the confines of the chamber, a controlled volume of high pressure fluid may be dispensed through the device.

Abstract: A locking cam plate for awning windows having a flat body portion adapted to be secured to the side wall frame of the awning window, slots formed on the body portion for pivotal and swinging movement of links connected to the awning window, an open slot formed on the forward edge portion of the body portion for receiving a locking pin mounted on the vent, the open slot forming a lip portion engaged by the locking pin when the vent is in a locked position and wall means connecting the lip portion and the body portion for strengthening the lip portion whereby the vent is prevented from being forcibly opened without actuating the operator.

Abstract: A closure locking and orienting device for securing the closure to a housing at an opening therein having a semi-circular groove on the periphery of the closure and a similar groove at the opening of the housing, the grooves being in opposing relation to form a circular groove about the closure. A bore extends radially through the housing and the closure, a further bore extending through the housing communicating with the circular groove and an elongated and substantially pliable member threaded through the further bore, received by the circular groove and extending about the closure to span the juncture between the closure and the housing with the other end of the pliable member extending through the radially disposed bore to lock the closure to the housing while orienting the closure with relation to the housing.

Abstract: A combined toy parachute and launching device having a tapered pole launcher, a parachute extending over the smaller end of the pole, a weighted knob secured to the larger end portion of the pole and a second knob removably positioned on the smaller end about which the parachute is draped. A sleeve is slidably mounted on the pole and secured to the ends of the parachute shrouds whereby upon throwing the pole into the air, and upon the pole having arrived at the apex of its flight, pole will fall downwardly as the parachute commences to gather air within its folds, the sleeve will slide upwardly on the pole and remove the second knob from the end of the pole to slide free of the pole. The parachute will then float freely in the air while the pole and the knob will fall to the ground.
