Filed: 1973-01-04
Abstract: 1453934 Electrical weighing system PROBE ENG CO Ltd 3 Jan 1974 [4 Jan 1973] 466/73 Heading G1N A load sensing transducer comprises a pair of generally flat conductors 1, 2, spaced parallel having leads 14 and separated by a cell or cells which are closed and having flexible side walls as in the plastics or rubber foam 4 and held apart by discrete resilient bodies 4 between which and conductors 1 and 2 an air space is left. Items 4 may be set in grooves in the plates or grooves formed by conducting plates attached to plates 1 and 2. Instead of item 4 a thin walled tube may be bonded to plates  1, 2 or thin strips of metal, plastics or rubber, with, at the edges, bonding, which is insulating if metal is used. Reinforcement by membranes 12 may be used, around or between the edges of plates 1, 2, which bear temperature sensitive elements 18, with leads 19, and are separated by insulators 15 from load-bearing plates 16, 17. Overload is indicated by the short circuit caused by stops 13. In Figs. 6 and 7, O is an oscillator of fixed amplitude and frequency, C the capacitance of plates 1, 2; A, A2 are high gain inverting amplifiers, Z is a stable impedance, # a phase splitter and SD a synchronous detector. Stray capacitances CS1 and CS2 and leakage resistance across C do not affect the circuit. One of the resistors Ro, Ri is an element 18. Negative coefficient thermistors, T, may form, with Rx, Ry, resistance Ri and output O/P 2  may be read on a digital voltmeter. Automatic or manual zero correction for barometric pressure may be applied to the input of A2, but is unnecessary with the circuit of Fig. 9, in which low pass filter F prevents mechanical oscillations of the load from causing voltage oscillation on C1, and charge flows into high gain inverting amplifier A3 until monostable circuit M is triggered causing counter CT to register and charge in Co to be discharged into the input of A3 in opposition. The action is repetitive and the total charge from Co equals the total charge from C1 and is proportional to the number of operations of M. Load removal does not cause counts because diode D conducts, but further loads cause additive counting.

Abstract: 1,094,241. Welding by pressure. P. ESSER [trading as MEYER ROTH & PASTOR]. Jan. 6, 1965 [Jan. 25, 1954]. No. 622/65. Heading B3R. In a chain welding machine for resistance butt welding links in which the link ends are pressed together under an initial low force and then under a higher upsetting force a means is provided to produce a counterforce acting against an energy source for the upsetting force, which counterforce can be suddenly reduced to permit the energy source to exert the full upsetting force. The chain link to be welded is located on a saddle and the link ends are pressed together by tools on the arms of upsetting levers. The upsetting levers are pivoted to links 7 on which adjustable compression springs 11 aet downwardly through a bridge 8, a rod 9 and a spring keep 10. A lever 13 under the control of a cam 23 acts on the keep 10 through links 12. A piston 19 of an hydraulic cylinder 18 is connected to the rod 9 so that fluid in the cylinder opposes the springs 11. In operation ith the link on the saddle and the keep 10 raised by the lever 13 the springs 11 are compressed and the piston 19 is at its highest position in the cylinder. The cam then releases the lever 13 so that the keep, rod 9 and bridge 8 are moved downwardly by the springs 11 and the tools act on the link which is heated by current supplied by electrodes. The hydraulic fluid in the cylinder space 20 which opposes the springs is controlled by a regulating valve 30 during this heating. When the welding temperature is reached determined by light or heat radiation or by elapse of time a control valve 32 is electro-magnetically operated to connect the cylinder to atmospheric pressure when suddenly an increased pressure is exerted on the link. The counterforce may alternatively be transmitted by mechanical means.

Filed: 1993-07-08
Abstract: Image processing apparatus for increasing the gray scale resolution of a graphic generated by an ink jet printing system wherein the graphic is made up of pixel areas on a receiving surface and each pixel area is comprised of a fixed number of potential dot positions printed with substantially equal sized dots. A sequential series of image density signals representative of the grey scale color intensity is generated from an original graphic and converted to a dot level value for each pixel. A pixel's dot level value is compared to a set of integer and non-integer values and pixels having dot levels falling between the same two sucessive integer values are selected. A predetermined dot level value is alternately added to the identified adjacent pixels so that one is increased and the other is decreased by the predetermined dot value. The resulting values are rounded off to the nearest integer and each pixel is printed with its respective new value. The resulting gray scale color intensity represented by the two printed pixels is the average of the sums of the two printed pixels' dot level values.
