Abstract: RECIPROCAL HYBRID MODE RF CIRCUIT FOR COUPLING RF TRANSCEIVER TO AN RF RADIATOR               ABSTRACT OF THE DISCLOSURE       A reciprocal transceiver to radiator coupling circuit uses both microstrip and waveguide modes of RF signal trabsmission (including a pair of nonreciprocal hybrid mode phase shifters) to gain size and weight advantages useful in feeding large scale phase arrays.  At the same time, the radar cross section of such array apertures is reduced by arranging separate nonreciprocal receive and transmit branches of the circuit to route spurious intra-circuit reflections of incoming RF signals to a matched termination.

Abstract: A method and apparatus for forming or modifying the cutting edges of razor blades, which comprises subjecting a stack of razor blades to ion bombardment from two ion sources in a vacuum chamber.  The ion sources are located on opposite sides of a plane which lies within the stack and parallel to the major surfaces of the blades and have the axes of their ion beams directed at the edges of the razor blades in the stack.  The ion bombardment is effected with ions of sufficient mass and energy, in relation to the material of which the razor blades are formed, to cause sputter removal of the material of the blades on both sides of the edges thereof to thereby form their cutting edges.  The apparatus includes a sealable vacuum chamber containing a workpiece holder and two ion sources for effecting the ion bombardment.

Abstract: ABSTRACT OF THE DISCLOSURE    A carbonless copying system which enables the formation of images that are capable of being detected by an optical character recognition (OCR) device.  A phenolic resin or reactive clay image-forming component is applied as a CF coating on a recording substrate. A first complementary image-forming component which is a microencapsulated dye precursor that is capable of forming a colored image when contacting the CF coating is applied as a CB coating to a transfer substrate.  A second complementary image-forming component, which is a microencapsulated dye precursor capable of forming a colored image when contacting the CF coating that is detectable by an OCR device, is applied as a CB coating to selected portions of the transfer substrate.  The dye precursor capsules, upon rupture by application of pressure, release the dye precursor which contacts and reacts with the phenolic resin or reactive clay to form colored images, with those images formed from second complementary image-forming component being capable of detection by an OCR device.  The carbonless copying system of the invention is particularly useful in credit card sales slip applications.

Abstract: A pile driving apparatus comprises a base frame having a platform for supporting ballast.  The base frame is equipped with a levelling device. The pile driving apparatus comprises a column positioned perpendicular with respect to the base frame and supported by steel supports.  At the top of the column is provided a lifting point.  A pile loading device consists of a cradle arm which is pivotally mounted to the base frame at the lower end of the column.  A hydraulic jack is operative for moving the cradle arm for loading piles onto the device.  A hydraulic piston bears a load onto a jack thrust plate, which plate is connected to a transmission plate by means of a shaped plate.  The higher end of the transmission plate is ridgedly connected to a pile thrust plate means of another shape.  The column is provided with an elongate slit so that when the hydraulic piston edges downwardly against the thrust plate correspondingly downward thrust is applied to the transmission plate.  This enables piles having a length substantially the same as the column to be driven into the ground.  The base frame levelling device comprises levelling jacks operative to adjust the back frame so that the pile can be positioned substantially level.

Abstract: Disclosed is a process of producing isopropylnaphthols by oxidizing diisopropylnaphthalenes with molecular oxygen in a liquid phase to form a reaction mixture which contains therein diisopropylnaphthalene monohydroperoxides and then decomposing the monohydroperoxides with acids to isopropylnaphthols. An organic layer is separated from the reaction mixture, lower aliphatic alcohols of 1-4 carbons are added to the organic layer, and the diisopropylnaphthalenes are crystallized while allowing the diisopropylnaphthalene monohydroperoxides to remain dissolved in the lower aliphatic alcohols, thereby to separate the mono-hydroperoxides from the diisopropylnaphthalenes. The isopropylnaphthols may be crystallized from aromatic hydrocarbons of 6-12 carbons. The isopropylnaphthols can be produced in high purity and in high yield by this process.

IPC: G01S11/02
Filed: 1990-10-25
Granted: 1995-10-24
Abstract: A method for measuring the velocity (v) of a moving target (A). Radio signals are transmitted by means of radio transmitter-receiver arrangements of both the measuring station (B) and the target station (A) and received at the opposite stations (A, B), the frequencies of which signals include Doppler shifts (fd) to be observed both at the measuring station (B) and in the measuring target (A). On the basis of the Doppler shifts (fd), the escape and/or approach velocity (v) ofthe target to be measured is determined relative to the measuring station (B). Radio signals are transmitted from the measuring station (B) and the target station (A), the frequencies of which signals deviate from each other by a relatively small frequency difference (fk) or by a Doppler frequency shift (fd),the absolute value of which small frequency difference remains at least as high as the absolute value of the largest expectable Doppler frequency shift (fdmax).A difference frequency or difference frequencies (fb, fa) of the frequency including the Doppler shift (fd) and received at the measuring station (B) and the target station (A) and of the reference frequency of essentially the signal frequency range developed locally are formed in such a way that a low-frequen-cy or possibly a zero-frequency signal at the target station is obtained as the difference frequency or frequencies (fb, fa). On the basis of the difference frequencies (fb, fa), the Doppler frequency shift (fd) is determined, by means of which the velocity (v) of the target (A) is obtained.
