Abstract: A diffuser attachment which is telescopically assembled to the air outlet end of a hand-held hair dryer and which is characterized by a forwardly flared body portion and by a diffuser plate concentrically mounted within the flared body portion and having a convex surface facing the flow of heated air from the hair dryer.
Abstract: In an electric bedcover of a type wherein a safety thermostat having a bimetallic element is adapted to deenergize a heater when the bimetallic element is heated sufficiently, as when an overheated condition occurs, an elongated flexible sensor of a type comprising a pair of conductors spaced from each other by a layer of material having a negative temperature coefficient of resistance is adapted to influence the bimetallic element through a resistor, which is mounted for heat dissipation to the bimetallic element, and a first circuit branch comprising the resistor, the conductors, and the layer between the conductors, in series with each other, is connected so as to maintain the conductors at different potentials when the heater operates, and so as to conduct sufficient current to cause the resistor to conduct sufficient heat to cause the bimetallic element to open the contacts when some part of the layer between the conductors is heated so as to act as an electrical conductor having a low impedance rather t
Abstract: An article fabricated from a resin (e.g. ABS, polycarbonates, polyethylenes, polyaryl ether, or polypropylene of platable grades) susceptible to softening when contacted with trichloroethylene or a mixture of trichloroethylene and methylene chloride is dipped into an alkaline detergent, rinsed, and immersed in an agitated bath (by volume, 90 parts of trichloroethylene, 9 to 10 parts of ethanol, and 0 to 1 part of methylene chloride--1 part of methylene chloride if the resin is polypropylene) to which copper or nickel has been added as a powder (50 to 150 microns, 200 to 250 grams per liter) whereupon the article is drained, dipped in an agitated bath of similar composition, and dried. Alternatively, the powder may be sprayed onto the article, after the article has been immersed in such a bath. Next, the article may be dipped in dilute nitric acid, rinsed and immersed in a non-catalytic bath for deposition of nickel.
Abstract: A food mixer having a stand with a mixer head pivotally mounted thereon for mixing foods is disclosed herein. The mixer includes means for cooling a drive assembly by drawing air in through a forward portion of the head and exhausting it out a bottom portion of the stand. The mixer is provided with a locking latch interconnecting the head and the stand in order to mix or knead properly heavy or viscous foods, such as bread dough. A pair of dough hooks, which are adapted to force dough away from the head during kneading, are detachably connectable to the head. A high outer wall turntable is rotatably supported on a base of the stand by a peripheral thrust bearing to provide a stable platform for a mixing bowl. Each mixing bowl used with the mixer has the same diameter bottom and lower contour regardless of bowl volume. A mechanical governor is connected to an electronic control to provide accurate motor speed regulation throughout the range of motor speed operation.

Abstract: A shaver includes a housing and a shaving head detachably secured to the housing. A modular cutting assembly is detachably mounted in the shaving head and includes a plurality of blades that are reciprocated within the head for cutting hair. The blades are joined together by pins and releasably secured to a mounting block. A biasing element secured between the mounting block and the blades biases the blades away from the mounting block to provide a floating connection. The mounting block is slideably positioned on a clip that is resiliently positioned within the shaving head. The shaver also includes a modular clipper assembly including a pair of blades reciprocally mounted within the shaving head. A clipper guard is slideably mounted in the housing for movement toward and away from the clipper blades and includes at least one sloped slot and a cutout portion with an inclined edge including at least one detent.

Abstract: A slicing machine having a housing containing an electric motor in driving connection with a circular blade for slicing meat, cheese and the like, the housing having an adjustable stop plate mounted thereon in proximity with a portion of the circular blade to permit a user to select a desired slice thickness and which also provides a blade guard when the slicing machine is stored. A wedge-shaped table member which slidably fits over the blade in engagement with the housing to provide a cover for storage and can be slidably fitted to said housing to provide a table extending from a front portion of said housing. A curved dish access member, having an integral arcuate ledge, formed integral with a rear portion of the housing provides means whereby a dish may be placed in proximity with the housing during operation, not only to receive sliced foodstuffs but also the juices therefrom.
Abstract: A gas lighter comprises a cylindrical tank having a filler valve and a burner valve connected to a burner by a conduit. An electrical ignition device is enclosed within a semi-cylindrical holder and a semi-cylindrical, axially displaceable actuating member, the actuating member being provided with means for operating the ignition device and means for opening the burner valve. The tank holder and actuating member are surrounded and held together by a one-part tubular sleeve having an aperture to permit manual movement of the actuating member.
Abstract: A process for providing surface layers of copper or copper alloyed with zinc on die castings of zinc or zinc alloys comprises a step of immersing the castings in an agitated bath containing an aqueous vehicle, which has been adjusted to a pH of from 8 to 10, and to which cupric oxide has been added as a powder in an amount of approximately from 200 to 250 grams per liter of the agitated bath. Cuprous oxide may be substituted for cupric oxide. At a pH not exceeding 8.5, the surface layer tends to be copper alloyed with zinc. At a pH exceeding 8.5, the surface layer tends to be copper. At a pH of 9, the surface layer of copper tends to be very adherent. The pH is adjusted by addition of sodium hydroxide, potassium hydroxide, or ammonium hydroxide, preferably sodium hydroxide.
Abstract: A heating element for use in an electric blanket or the like including conductors spaced apart in a positive temperature coefficient (PTC) material which serves as a self-limiting heater. The conductors are separated by a spacer which prevents the conductors from engaging each other when the PTC material softens or melts during annealing thereof. A coating of material having a higher melting point than the PTC material is placed over the PTC material to maintain its shape during the annealing process.
Abstract: In an apparatus for thermal treatment of semiconductors, a substantially spherical portion of a cap for a tube is confined between distal ends of a plurality of members and distal ends of a plurality of springs, whereby problems arising from angular deviation are overcome. The framework supporting the cap confining means is biased toward the tube.
Abstract: A remote-controlled pressure regulator comprises a stepping motor, which is operatively connected to a tiltable arm engaging a connecting rod, so as to adjust loading of a pressure-regulating unit.
