Filed: 1976-03-25
Abstract: 1503852 Ultrasonic flowmeters WESTINGHOUSE-ELECTRIC CORP 25 March 1976 [18 April 1975] 12023/76 Heading G1G A volumetric flowmeter comprises circuitry for generating respective electrical signals each proportional to average fluid velocity along a respective one of n paths in a pipe, weighting circuitry for multiplying each generated signal by a respective weighting factor wi, and summing circuitry for summing the multiplied signals, each of the n paths being located a distance Rx i  from the pipe centre where R is the pipe radius, i is the particular path number,  As shown in Fig. 1 upstream and downstream ultrasonic transmitter/receiver units T1, T2, T3, T4 and T 1 ', T 2 ', T 3 ', T 4 ' are used to supply signals to the generating circuitry. Thus, the average velocity along four flow-paths is measured, each flowpath being in a vertical plane contain a respective one of the acoustic paths L1-L4. As shown in Fig. 5, the transmitter/receiver units are arranged so that the four flow-paths are horizontal. Units 30 1 -30 4  under the control of a timing circuit 32 control the energization of and receive signals from the transmitter/receiver units and each produce outputs related to the time difference #t between arrival of acoustic pulses at the respective receiver unit pairs and the time t 1  for an acoustic pulse to travel from the upstream transmitter to the downstream receiver. These outputs are applied to respective units 351-354 which each produce an output proportional to #<SP>t</SP>/t 1 (t 1 +#t) and these outputs are applied to respective units 40 1 -40 4  where they are multiplied by the quantity R<SP>2Li</SP>/Cos#i where Li is the path length between the respective transmitter/ receiver units and #i is the angle such paths make with the direction of fluid-flow. The outputs of the units 40 1 -40 4  are applied to respective weighting circuitry 45 1 -45 4  whose outputs are summed and averaged over a predetermined number of acoustic pulses in circuitry 50, whose output is displayed at 52 as a measure of the volume flow rate.

Title: Constant velocity vector generator
IPC: G09G1/10
Filed: 1970-03-13
Abstract: 1298385 Cathode-ray tube circuits RCA CORPORATION 13 March 1970 [19 March 1969] 12098/70 Heading H4T Vectors are traced at constant velocity on the screen of a cathode-ray display tube by deflecting the beams in orthogonal (X:Y) directions by means of ramp waveforms the slopes of which are proportional to cos # and sin # respectively where # is the angle which the vector makes with one of the directions X, Y. This follows from consideration of the equation of resultant vector velocity V=VK<SP>2</SP>cos<SP>2</SP>#+ K<SP>2</SP>sin<SP>2</SP># since cos<SP>2</SP># + sin<SP>2</SP>#= 1 for all values of #. Thus all vectors (which may form parts of alpha-numeric symbols) are produced with constant brightness and constant trace thickness. As shown in Fig. 1, a digital data source 2 supplies signals indicative of the initial positions Xo, Yo to respective D/A converters 4, 12 and signals indicative of the cos and sin of the vector angle # to respective D/A converters 6, 14. The outputs of the latter are then supplied to respective integrators 8, 16 the output ramp waveforms of which are combined in respective summing means 10, 18 with the outputs of the D/A converters 4, 12 and the outputs from the summing means are then fed via deflection amplifiers 36, 48 to the X and Y deflection coils 54, 56 respectively. The vector tracing operation is started by an output from the data source 2 on line 21 which causes a control circuit 20 to unblank the beam of the display tube 26. When the tracing of a particular vector has been completed a comparator 22, supplied via the data source 2 and a D/A converter 24 with a magnitude proportional to the X-co-ordinate X #  of the vector end point and with the X-deflection magnitude from summing means 10, supplies stop signals to the integrators 8, 16 and supplies a vector generated signal to the data source 2 over line 64. Alternatively, the Y-co-ordinate of the vector end point and the Y-deflection magnitude from summing means 18 may form the inputs to the comparator 22. In a further arrangement (Fig. 4, not shown) the D/A converter 24 and comparator may be replaced by a binary counter supplied from data source 2 with a binary signal indicative of vector length and with a train of timing pulses having a period proportional to K which cause the counter to count down to zero and supply a signal to the control circuit 20. The symbols traced on the tube screen may be recorded on photosensitive material to provide the basis for a printing master for a page of print.

Title: Improvements in and relating to method of inhibiting the chemical reactive capacity of ferro-manganese
IPC: C23C22/24
Filed: 1936-04-30
Abstract: The chemical reactive capacity of powdered ferromanganese is inhibited by forming an oxide coating thereon.  The oxide coating may be formed by heating the powder in air at temperatures not exceeding 250 DEG  C. or by adding water to the powder, boiling the mixture dry, and then heating for about 10 minutes at about 200 DEG  C. Alternatively, the powder may be simply moistened with a solution of an alkali metal dichromate or moistened with the solution, dried at 100-150 DEG  C., and screened to break up the lumps.  Another method consists in moistening the powder with a dilute solution of potassium permanganate, boiling the mixture dry, and heating the dried residue at about 200 DEG  C. for about 10 minutes.  The process is particularly applicable to preventing reaction between ferromanganese and liquid sodium silicate in flux pastes used for coating welding electrodes, the ferromanganese being treated by one of the above described methods prior to incorporating it in the flux paste.

Abstract: <PICT:0570837/IV/1> A polarizing sheet of plastic material is coated with a relatively hard light-transmitting resin polymerized in situ and secured thereto either autogeneously or by an adhesive.  The polarizing sheet may comprise polarizing particles in a resin &c., a linear hydrophilia polymeric plastic, or a plastic having long, straight-chain molecules having conjugated systems of double bands, the particles or molecules being substantially similarly oriented. The coating may comprise methyl methacrylate or other unsaturated methylene compound, a vinyl compound, copolymers thereof, with or without hardening agents; various suitable substances are specifically set out.  The adhesive, when used, may consist of a resin of urea-formaldehyde type or phenol-formaldehyde type, or of an alkyd resin.  The material, or combination of materials, forming the coating is, preferably, so chosen that its refractive index is substantially that of the polarizing sheet for transmitted light. Polymerization may be effected by heating or by ulra-violet radiation.  The Figure shows a polarizing sheet 10, the surfaces of which are not necessarily flat or smooth, secured by adhesive layers 12 to out layers 14 of highly - polymerized resinous material having optically smooth outer surfaces.  The sheet 10 may be first coated with a solution of an adhesive such as "polymerise," the solvent being then mainly evaporated by baking, and may be suspended in a mould having optically smooth glass moulding surfaces.  The resinous material may then be poured into the mould and polymerization effected by first heating to a low temperature, at then for from eight to fifteen hours at a high temperature; a surface active compound may be provided in the resinous material to facilitate free cleavage of the finished sheet from the mould.  The mould may have plane walls, or curved walls for the production, with or without subsequent grinding of lenses embodying polarizers. Specification 548,759 is referred to.
