Abstract: A cosmetic breath freshener composition having slow release comprising a multiplicity of microencapsulated liquid droplets of flavoring material contained in a carrier. The microencapsulated droplets are soluble in the saliva in the mouth to release the flavoring material. The composition can be used in conjunction with a dental adhesive particularly for use with dentures to release the flavoring material at a sustained rate for long periods of time in the mouth to mask bad breath.
Abstract: A method for effecting percutaneous pain alleviation in which right-angled sawtooth shaped electrical pulses are produced at electrodes for percutaneous application to bodily areas experiencing pain. One of the electrodes is located at the site of the pain while the other electrode is moved to different sites of the region of the pain. At the same time the amplitude of the electrical signals is measured for each site until a maximum amplitude site is located. Thereafter, an electrode is continuously positioned at the located site for a given period of time for continuous application of the electrical pulses which may be selectively varied in amplitude in the range of zero to about 100 volts peak-to-peak and the output current controlled from 1 MA to 40 MA, while the pulse repetition frequency may be selectively varied in the range of about 10 HZ to 100 HZ.
Abstract: The specification discloses a structure for locating integrated circuits on a substrate by etching V grooves in a silicon substrate arranged to co-operate with spheroidal connectors on the integrated circuit. Contact pads are located in the V grooves whereby connections are made to the integrated circuit through the spheroidal connectors.
Abstract: A strong focusing megatron has a hollow toroidal chamber in which a plasma of isotopes of hydrogen support an orbital current driven by a changing magnetic field whose amplitude is controllably variable and whose direction is generally coaxial with the major axis (z-axis) of the toroidal chamber while the current is stabilized by a strong focusing magnetic field of alternately focusing and defocusing sections whose field is generally in the region of the toroidal chamber.
Abstract: A large scale integrated circuit package including a base or substrate section and a lid structure of thermally conductive material to which the chip or die of the package is mounted. A frame defining a recess for the chip is provided on the lid and the frame carries conductive tracks which are coupled to the connector pads of the chip or die. The base has a recess which accommodate the chip and frame and which is closed by the lid structure. The base of the recess is provided with conductive tracks which co-operate with those on the frame. The electrical connections between the two sets of tracks is formed by thermo-compression techniques.
Abstract: It has been found that fluid, semi-fluid, plastic products as well as powder or granular products packed in plastic tubes have caused great problems in tropical countries due to the change in temperature between day and night. In some cases the products have expanded and burst open the closure of the plastic tube so that the contents ran out or, due to their constituents, the products have caused deterioration of the protective properties of the plastic tube. By choosing a plastic tube or olefin plastic and sealing said plastic tube with closures of olefin plastic, as well as orientating the plastic molecules in the tube in both axial and radial direction, a plastic seal is obtained which is not affected by the products enclosed and which also resists expansion of the products without rupturing.
Abstract: A swinging door construction for a vehicle comprising a door panel having upper and lower swing arms coupled thereto and connected to a rotatable swing column. A drive mechanism is secured to the body of the vehicle and operatively engages the swing column to rotate the same and effect swinging of the door. The lower swing arm is connected to the swing column by a connecting member which extends upwardly above the drive mechanism and is secured to the swing column.
Abstract: A method of dispensing fluid or semi-fluid liquids or pastes in which the liquid or paste is contained in a container having a top flexible dome and a bottom dome connected at their open ends to each other. The method comprises pressing the top dome downwardly toward the bottom dome and forcing the top dome into the bottom dome and discharging the liquid or paste from the bottom dome under the action of the forcing of the top dome into the bottom dome. The top dome can be formed with an internal annular bead which is displaced along the inner walls of the bottom dome to scrape off material stuck to the inside walls of the bottom dome.

Abstract: Apparatus used in identifying a person by means of pressure patterns and X-Y movements of a stylus associated with a signature includes first and second spaced and parallel planar conductor means with an excutcheon means for defining on an exposed surface of one of the elements to provide a writing surface for a user who, by means of a stylus, exerts a varying pressure pattern via the lamina onto one of the elements to produce a varying capacitance signal while at the same time interrupting light paths to produce X-Y coordinate signals.
Abstract: In electromagnetic communication different data streams share a common communication medium by being multiplexed. Each individual data stream employs its own unique modulation waveform set. A receiver for a given data stream comprises correlators for the waveforms in the corresponding modulation waveform set. If the waveforms in all the different modulation waveform sets are not orthogonal, then the output of correlators at a given receiver will not only contain the desired information components of the data stream to which they are matched but also components from the other data streams. This is termed cross-talk. Processors are provided which are responsive to the outputs of all waveform correlators. They provide a means for detecting the original data stream information in the presence of cross-talk. When there is no noise in the communication transmission the processors cancel the cross-talk.
Abstract: A seamer for completing two preformed abutting sheets has a wheeled body for straddling by rolling over the sheets. Sets of die rollers and opposed backing rollers longitudinally aligned along the body are driven by a drive unit after being pivotably positioned in operative opposed relationship. A control mechanism including sensors extending from the body seeks the presence of the preformed sheets or an obstruction to control the operation of the drive unit.
Abstract: A method and apparatus for driving a stepping motor by angularly displacing the revolvable magnetic field with respect to the rotor by a first displacement angle in a given direction of revolution and then revolving the revolvable magnetic field, preferably with linearly increasing velocity and therefore maintaining constant displacement angle between the field and the rotor until the rotor rotates at a second velocity.
Abstract: Apparatus for the batch filtration of suspensions comprising a plurality of press-chambers and filter belts for transporting the suspension stepwise through the press-chambers, such that after pressing the suspension in the first press-chamber and before entry of the resultant press cake into at least one subsequent press-chamber, the structure of the press cake is changed by shearing forces and the press cake is curved and at least partially torn apart. In the case of municipal sludge the flaked sludge is subjected in a first pressing zone to slow increase of pressure and a pressure of up to about 1 bar and is subjected in at least one following press zone to a pressure increase which is more rapid than in the first press zone, up to a pressure of about 3 bars.
Abstract: A replacement for a light transmitting panel of a ceiling light fixture having a plurality of replaceable fluorescent lamps for reducing the number of lamps in the fixture. The replacement includes a light transmitting part partially covering the body of the fixture for partially surrounding one or more of the fluorescent lamps for permitting light passage therefrom, and light reflectors covering the remainder of the fixture body such that at least two other fluorescent lamp can be removed and rendered inoperable in the fixture. The reflectors are operatively positioned in facing relation to the light transmitting part to reflect downwardly light transmitted thereto. A door frame is detachably engageable with the fixture body and operatively engages both the light transmitting part and the reflectors to mount the same on the fixture body.
Abstract: An angle digitizer receives signal representing the sine and cosine of the angle to be digitized. The voltages are fed to orthogonal pairs of input terminals. Between each two input terminals is a set of equivalued resistors to form a resistor ring. At the junction of each pair of resistors is an output terminal. Each pair of output terminals is connected to the input terminals of a signal amplitude comparator which compares the magnitude of the signals at its inputs to give a digital signal in accordance with which is greater. For each comparator the output terminals of the resistor ring are selected such that the signals are in a direct antiphase relationship.
