Abstract: Branched alkyldiorganoaminopyridinium salts have been found useful as phase transfer catalysts for facilitating nucleophilic aromatic substitution. For example, the 2-ethylhexyl salts of dialkylaminopyridine, can be used as stable phase transfer catalysts for making aromatic etherimides by reacting substituted phthalimides and alkali metal phenoxides in the presence of a non-polar organic solvent.

Abstract: A novel thermal ink jet head is disclosed in which the jetting resistors (20), fluid interconnections, ink reservoir, electrical connections (30, 40), and jetting orifices are fully integrated to provide an inexpensive, disposable jetting head. The entire hydraulic ink system is sealed to eliminate user interaction with the liquid ink, and ink can only exit the head via the jetting orifices under the influence of the jetting resistors. Once the ink is expended the user disposes with the old head and installs a new one by breaking and making a simple mechanical and low voltage electrical connection.

IPC: H03H11/12
Filed: 1984-10-19
Abstract: Described is a novel technique and associated arrangement for determining the noise-free value of a system parameter (e.g., head position in a disk drive) which is time variable and (usually) has a noise component as detected. The technique involves processing the (as detected) noise-including value and passing it through "Second Order/ Summing" filter means. 
     For instance, the technique is described as particularly useful with the "track-following servo" (part of the transducer positioning means) in a high density disk file (where track density is higher than usual) to secure superior head- displacement error values which are more noise-free. Thus, (see Figure 4), a pair of first values V 8 , V b  are secured by detecting motor current sense voltage V i , integrating it with respect to time and passing the result through a pair of novel "second order filter" means - one hand-pass (F 1 ), the other low-pass (F 2 ); while also securing a third value V c  by detecting position error (signal voltage, including noise components) in the usual manner and passing it through a "second order low-pass" filter F 3 ; then algebraically summing these to secure a relatively noise-free position error signal V xo   
     
       
         
       
     
     Thus, the summing filter array gates the position-error voltage but attenuates the (mechanical) noise component (cf. filters F 2 , F 1  centered at w o - e.g., 600 Hz is satisfactory here). 
     Such "second order" filters are novel in themselves, and particularly as so applied (most especially as so-used in such a servo system).

Abstract: @ The invention is a method for making an electrically conductive path on the wall of a passage through a substrate. It is especially useful for connecting electrically conductive paths (25) on opposite sides of a circuit board (20). The method is characterized by the steps of forming a tapered passage (21) through the substrate (20) that connects to at least one conductive path on each side of the substrate (20), filling the tapered passage (21) with an electrically conductive powder (10), applying pressure with a tapered die (30) to compact the powder (11) against the wall of the passage (21) without blocking the passage, and then heating the compacted powder (11) to a temperature that increases the conductivity and ductility of the compacted powder (11) and its adhesion to the substrate (20) without adversely affecting the shape or condition of the substrate (20).

Abstract: A semiconductor device such as a dynamic read/write memory or the like is made by a twin-well CMOS process that employs a minimum number of photomasks. Field oxide isolation areas are formed in nitride-framed recesses so a relatively plane surface is provided, and a minimum of encroachment occurs. Both P-channel and N-channel transistors are constructed with silicided, ion-implanted, source/ drain regions, self-aligned to the gates, employing an implant after sidewall oxide is in place, providing lightly-doped drains. The threshold voltages of the P-channel and N-channel transistors are established by the tank implants rather than by separate ion-implant steps for threshold adjust.

Abstract: A side and heel lasting machine. The machine serves to adhere the unwiped margin (107A,107B) of a shoe upper assembly (102), whose toe portion (107) has been wiped, to the periphery region of the assembly insole (103). Lasting pads (1A,1B) are employed to keep the margin (107A,107B) in position during application of adhesive from nozzels (105A, 105B) that are spring loaded to press outwardly and track the upstanding margin (107A,107B) when adhesive is applied in the region ( A) between the insole (103) and the margin (107A,107B). The pads (1A,1B) are then raised and urged inwardly to press the margin (107A,107B) onto the insole (103). The top edge (2A) of inner lasting pads (1A) are folded onto the insole during the wiping action; the direction of forces upon the top edges (2A) of the lasting pads (1A) is changed during wiping to increase downward wiping forces upon the margin (107A,107B). A quick-release mechanism (7,7A,7B,7C) is provided to permit removal and replacement of the lasting pads (1A,1B) without need to remove any screw-type fasteners.

Abstract: This invention relates to apparatus for and a method of measuring radiation field strength which uses a pulse enabled detector (Geiger-Mueller tube) and is based on the equation R = K/t, where R is the radiation field strength, t is the time till first strike, and K is a proportionality constant for the given apparatus. The apparatus and method substantially eliminate measurement errors due to circuit propagation time delays and slow drift conditions, Geiger-Mueller tube turn-on time and response curve variations, and the need to manually calibrate the measurement apparatus in high radiation fields to compensate for time errors. When mean times are short the calculation of the rate is an estimation of the mean time to strike, which in turn is equivalent to estimating the mean (1/nR) of an exponential probility distribution function (PDF) nRe -nR . This function has the property that the expected value for the arithmetic mean of any right hand segment of the curve is always the same provided that the time axis is adjusted so that the starting point of the selected segment is zero. The curve is trimmed dynamically each time a new rate is calculated. 
     An individual count of strike events is kept (28) for N separate but consecutive time units, and the counts for the later occurring events are lumped together as the Main Event. After the data collection period ends, a total accumulated time and accumulated count are constructed. This construction begins by examining the Main Event data. If enough data is present to derive a statistically acceptable estimate (250-500 events) the data in the first N time units is ignored. If more data is desirable, the data is factored in, one time unit at a time starting backward from the event count corresponding to the time unit with the longest time. The total time is now adjusted so that the starting time corresponding to the selected portion of the PDF is zero. This adjustment also includes a further adjustment which compensates for the digital approximation of the continuous variable time, corrects most of the error caused by the discrete clock frequency, and helps to adjust for additional curvature errors which are most pronounced when the mean time to strike is close to the clock time. An estimate for rate is made by dividing the total adjusted number of counts by the total adjusted accumulated time and multiplying by a scale factor.
