Title: Methods and machines for assembling washers with rotary fastener members
IPC: F16B27/00
Filed: 1971-08-17
Abstract: 1356454 Assembling fasteners with washers ILLINOIS TOOL WORKS Inc 17 Aug 1971 [12 Nov 1970] 38574/71 Heading B3A [Also in Divisions B8 and F2] Fastener members 104, e.g. screws, skirted nuts, are assembled with washers 62 by cascading washers 62 into pockets 86 moving along a closed path, conveying the washers 62 which do not enter the pockets 86 back to rejoin the flow of washers 62 being cascaded, feeding fastener members 104 into alignment with the washers 62, telescopically assembling the fastener members 104 and washers 62 together and deforming each fastener member 104 to secure the washer 62 thereon. Conical washers 62 are fed by a vibrating channel 68, Fig. 6, onto an inclined rotating disc 84 which receives correctly oriented washers 62 in peripheral pockets 86. Unaccommodated washers 62 are delivered onto a vibrating channel 66 and are recirculated to the disc 84. The washers 62 are supplied to the channels 66, 68 from a vibratory hopper 60 when the level of washers 62, as detected by feelers 80, falls below a predetermined level. Before each washer 62 is brought into alignment with a screw blank 104, Fig. 9, positioned on a rotary feeder 56, the screw blanks 104 are raised by cam surfaces 114, 118. The screw blanks 104 are fed by a guide rail 96 to the rotary feeder 56 which comprises spaced plates 100, 102, Fig. 18, having aligned recesses 98, 98a, incorrectly oriented blanks 104 being ejected by a spring biased finger (110) (Fig. 32, not shown). When a screw blank 104 is aligned with a washer 62, it is pushed into the washer 62 by a leaf spring 120. The partially assembled blank 104 and washer 62 are transferred from the rotary feeder 56 into recesses 138 of a rotating drum 136, whereupon complete assembly is achieved by a leaf spring 140. If a blank 104 is not properly positioned on the drum 136, it fails to clear an arm 145 which causes a clutch 224, Fig. 18, to slip and the machine to stop. Properly assembled blanks and washers are directed by a bar 158 to a guide rail 162 leading to thread roller dies (190, 192) (Fig. 43, not shown) which increase the shank diameters so as to secure the washers in position. Washerless blanks 104 are able to clear the undersurface of bar 158 and are retained on the drum 136 from which they subsequently fall by gravity. As each disc pocket 86 of the disc 84 moves into alignment with the recesses 98, 98a of the feeder 56, the speed of the conveyers is retarded to facilitate assembly by moving, by an arm 426, Fig. 18, a gear 202 laterally out of alignment with the axis of a shaft 210. The end of the shaft 210 is connected to a crank arm 208 carrying a roller 206 which engages the gear 202. The disc 84 may be vibrated and can be laterally and circumferentially adjusted relative to the rotary feeder 56. The rotary members 84, 56, 136 may be replaced by endless chains moving in oval paths.

Abstract: 1,045,389. Semi-conductor device. NIPPON ELECTRIC CO. Ltd. Sept. 10, 1965 [Sept. 10, 1964], No. 38823/65. Heading H1K. A semi-conductor device comprises a monocrystalline low-resistivity body with an inclusion of the same conductivity type but high resistivity in one face and an inclusion of the opposite conductivity type within and forming a PN junction with the first inclusion. A planar diode of this type, Fig. 2, is made in multiple by first epitaxially growing a high resistivity 0.6 ohm cm. layer on a 0.002 ohm cm. substrate 2, diffusing impurity into parts of the layer through grown oxide masking to render areas 7 of low resistivity, diffusing impurity of the opposite conductivity type through further oxide masking into the thus isolated high resistivity areas 1 to form PN junctions 5 and applying ohmic contacts through the masking at 6. Alternatively the PN junctions are formed first by diffusion and the areas 7 subsequently converted to low conductivity by alloying through oxide masking. In this case the latter masking is removed and replaced by evaporated oxide before the contacts are provided. Equivalent elements can be produced by etching pits in one surface of a low resistivity wafer, epitaxially growing high resistivity material in the pits and then forming junctions within the grown material by diffusion. The described structure avoids the relatively high resistance inherent in conventional planar epitaxial diodes at frequencies where skin effect is important by reducing the surface path between the PN junction and the low resistivity substrate.

Title: Interarterial blood pressure onset detection and computation of electromechanical interval
IPC: A61B5/0285
Filed: 1976-09-22
Abstract: 1504491 Measuring the electro-mechanical interval AMERICAN HOME PRODUCTS CORP 22 Sept 1976 [22 Sept 1975] 39311/76 Heading G1N(E) In an apparatus for measuring the time interval (the electro-mechanical interval) between the occurance of a myocardial electrical impulse (R 1 ) Fig. 2A (not shown) and the onset of the resulting blood pressure pulse (P 1 ) Fig. 2B (not shown), the myocardial impulse is used to start a timing circuit 6. The timing circuit is stopped when a parameter of an "electronically processed" version of the blood pressure pulse waveform reaches a predetermined value. The "electronic processing" consists of providing an electrical signal representing the blood pulse waveform, forming two identical signals (see bottom part of Fig. 3), then delaying 12 and inverting 13 one of these signals and subsequently combining 20 the two signals. The parameter detected may be the peak 22 of the combined waveform at the "zero-crossing point". Thus, as can be seen from Fig. 3, the onset of a "R" wave in the E.C.G. signal of a patient is detected 4 and starts a ramp generator 6 which stopped by a pressure peak detector 22 that senses when the electronically processed blood pressure has reached a peak. The pressure peak detector 22 actuates a sample and hold circuit 24 and a reset circuit 26 that sets the ramp generator 6 to zero. The sampled signal is then sent to a subtracting circuit where a value equivalent to the delay introduced by the delay 12 is subtracted therefrom to provide a signal proportional to the electromechanical interval.

Abstract: 988,586. Automatic control of current and voltage. ROTAX Ltd. Oct. 31, 1962 [Nov. 7,1961], No. 39783/61. Heading G3R. In a current regulating circuit similar to that described in Specification 988,585, the time delay switch is omitted and a capacitor 28 is connected across the Zener diode 22. On initially connecting the circuit to a source of power,the reference voltage across diode 22 is not established until capacitor 28 is charged; during this time the reference voltage is provided by the capacitor 28 and is therefore lower than normal whereby the risk of high current flowing in the output circuit during the time taken for capacitor 26 to become charged is minimised. Capacitors 26, 28 are so chosen that the voltage across them builds up at approximately the same rate.
