Abstract: 1390887 Glass composition; crossover dielectrics E I DU ZONT DE NEMOURS & CO 14 June 1973 [14 June 1972] 28452/73 Heading C1M [Also in Division H1] A glass composition consists essentially of, by weight, 25-40% SiO 2 , 5-15% TiO 2 , 7-12% Al 2 O 3 , 10-30% BaO, 10-26% ZnO, 2-10% CaO, 2-8% B 2 O 3 , 0-2% MgO and 0-4% Bi 2 O 3 , the total weight of BaO and ZnO being from 30 to 40% of the total weight of the composition. The glass may be used in the production of crossover dielectrics for use in printed circuits. The composition in finely divided form, e.g. 1-15 microns, is applied dry or in the form of a suspension in an inert liquid vehicle of which many examples are given. The composition is preferably screen stencilled on prefired metallized ceramic dielectric substrates. After application of the composition the printed substrate is fired, either prior to or subsequent to the application of a further metallizing composition to selected areas of the assembly in such a way that the upper metallization crosses the lower metallization only at points where the glass composition has been applied, e.g. at 850-900‹ C., to produce a partially crystallized glass in the fired dielectric comprising a crystalline phase dispersed in a glassy matrix, the crystalline phase being 20-48% by weight of the glass and consisting essentially of celsian (BaAl 2 Si 2 O 8 ) as its major component together with minor amounts of sphene (CaTiSiO 5 ) and zinc orthosilicate. The glass may be heated at a peak temperature of 850-900‹ C. in 45 minute cycles with 10 minutes at the peak temperature. The thickness of the fired crossover dielectric specified in an example is about 2 mils. A comparative example discloses a glass composition comprising 33% SiO 2 , 10% TiO 2 , 10% Al 2 O 3 , 12% BaO, 5% ZnO, 9% CaO, 10% B 2 O 3 , 1% MgO and 10% Bi 2 O 3 .

Title: A method and apparatus for reducing the temperature and pressure of superheated steam
IPC: F22G5/20
Filed: 1953-10-19
Abstract: 753,588. De-superheating steam. FAIRELY, T. Oct. 19, 1954 [Oct. 19, 1953], No. 28770/53. Class 55(2). [Also in Group XIII] Superheated steam is usefully disposed of during the starting up or closing down of a boiler, by passing it through a constricting orifice of fixed area and from thence through a pipe run of constantly increasing diameter, during which time it is sprayed with a cooling liquid, preferably water, the steam being eventually passed into immersion heaters in a liquid to be heated, preferably, feed water. The boiler 1 has the usual header drum 2, superheater 3, main stop valve 5 leading to turbine 6, and a leak-off valve 4 for withdrawal of the steam when the turbine is out of use, e.g., when starting up or closing down the boiler. Condensate from the turbine 6 is returned to the feed tanks 7. The leak-off steam is desuperheated by passing it through an orifice plate 21A into a pipe 21 having a greater section than the preceding pipe 4B, and in sequence through other orifice plates 21B, the pipes receiving the steam from the orifice plates becoming progressively of larger section. Each orifice plate consists of a disc 24 held between pipe sections 22, 23, a hard steel insert 25 being held in place by the flange 22A, the insert having a tapered bore 25A. Water is supplied to the space 24B around the insert from a pipe 26, so that the increased speed of the steam through the bore 25A draws the water through the passage 24C into the pipe 23 to mingle with, and cool, the steam, which, after its final passage through an orifice plate 21B and mixing with water, passes through pipes 21C to immersion heaters 27, as described in Specification 700,531, [Group XIII], in the feed-water tanks 7. The cooling water for the orifice plates and the heaters 27 is supplied either from tanks 29 which are replenished by the feed pump 8 and pipe 9A, or, by adjustment of the three-way valve 30, the high pressure supply may be taken from the pipe 9A through the pipes 9B, 26C. The steam from the pilot safety valve 4A is passed through the orifice plates &c. to the feed-water tanks. In a modification, a number of boilers have their superheaters connected through separate leak-off valves to a common orifice-plate line.

Abstract: 1,161,232. Control systems for servomotors. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 28 June, 1967 [29 June, 1966], No. 29110/66. Heading H2J. [Also in Divisions G2 and G3] A servomotor control system suitable to move in unison the two independent jacks controlling the gap width of a rolling mill, comprises servomotors SA, SB respectively controlled by summating amplifiers A1, A2 to each of which is fed a common control signal d representative of a desired motor position, a negative feedback signal (-)a, (-)b representative of the motor position, and a third signal k(b-a), k(a-b) obtained from a coordinator C, this last signal only appearing when the motors fall positionally out of step and serving to vary the motor speeds to restore synchronous movement. The co-ordinator C comprises a differential amplifier including operational amplifiers A3, A4, A5 which respectively reverse the sign of the feedback signal (-)a, sum the two signals (+ )a, (-)b and multiply the result by a factor (-)k numerically greater than unity, and reverse the sign of the resultant signal k(b-a) before passing it to the amplifier A2. In operation the system is more sensitive to the signals k(b-a), k(a-b) than to the signals (d-a), (d-b), the effect being to slow down or reverse the servomotor which is ahead and speed up the lagging motor. The co-ordinator C may comprise an arrangement of transistors and resistors, Fig. 2 (not shown), the transistors including first and second long-tailed pairs separated by buffer amplifier stages to produce the required sensitivity.

Title: Digital electric shaft position indicator
IPC: H03M1/00
Filed: 1956-09-24
Abstract: 809,343. Digital electric liquid level indicators. BENDIX AVIATION CORPORATION. Sept. 24, 1956 [Sept. 28, 1955], No. 29164/56. Class 40 (1). A device for producing digital electric signals representative of the level of a liquid 4 in feet and inches by means of mechanically connected commutating discs there being one disc per denomination, one 24 for inches and one 32 for feet, is characterized in that the higher denominational disc has two sets of sensing brushes one set being positioned slightly ahead of the theoretical sensing position 52 (i.e. excluding back-lash in gears &c.) and one set being positioned slightly behind the theoretical position, the set that is actually used to produce the output signals being selected by a relay 48 which is controlled by one of the brushes on the lower order disc in such a way that the output signals from the higher order disc change precisely when the lower order disc passes through its zero position, thereby eliminating possible errors. For example, when the discs are in the position corresponding to 12 feet 11 inches (in which position they are shown) relay 48 will be energized and the brushes C5-C8 slightly behind the theoretical position 52 will be operative. If the shaft then rotates in a positive direction, at the instant the inches disc 24 passes from 11 to 0 relay 48 will be de-energized, the brushes C5<SP>1</SP>-C8<SP>1</SP> will be operative, and the signals produced by the feet disc will represent 12, whereas had there been only one set of brushes co-operating at the theoretical position with the feet disc 32, there would be the possibility of the output signals from that disc changing just before or after the inches disc passes through zero, that is in going from an indication of 12 feet 11 inches to 13 feet 1 inch it would be possible to pass through the indications 13 feet 11 inches or 12 feet 0 inch or 13 feet 0 inch. The present invention eliminates this ambiguity. Each disc represents decimal members by a four-element monophyllic code the inches disc going from 0 to 11 or the feet disc from 0 to 15.

IPC: B21D35/00
Filed: 1933-10-25
Abstract: 408,890. Making toys and toothed gearing. FROMMHERZ, J., 5, Sybillastrasse, Ettlingen, Baden, Germany. Oct. 25, 1933, No. 29553. [Classes 83 (ii) and 83 (iv).] Angular bending; punching; shearing; stamping.-A press for making parts for toys is operated by a hand lever 8 with cams 9 and 10 whereby the dies 14 are given a full or a part stroke. Various tools may be fitted in the press ; as shown in Fig. 4, for bending at right angles ; Fig. 5 for pressing a channel Fig. 6 for bending the channel into a tube Fig. 7 for flanging; Figs. 8 and 9 are two views of shearing dies ; Fig. 10 shows platen dies for grooving a shaft, e.g. on which a wheel can be slipped and held ; Fig. 11 embossing dies ; and Fig. 12 tooth cutting dies. The work strip 40 is pushed by hand step-by-step into the press, being guided by a guide 38, Figs. 15 and 16, mounted in a perforated bar 34 which is pivotally secured at its end under the lower die and carries a pin 37 which is sprung by hand from one hole to another in the bar 34 to effect the step-by-step advance. The bar 34 can also assist in cutting teeth in the disc 53, Fig. 18, (which is first cut circular by rotating it by hand step-by-step under the shear dies) by using a tooth spacer slipped on the V- tooth cutting die bolster, an arm 45 carrying a spacing pawl 47. A spring 48 holds the arm 45 so that the tooth 47 can be replaced in each newly cut V-notch to space the disc for cutting the next notch accurately. The distance of the first hole 36, Fig. 13, from the die centre 41 is greater than the pitch of the holes 36 to allow a constant addendum on the teeth from the pitch circle, so that any larger or smaller gear wheel to be cut is centred at one or other of the holes 36 during cutting, and the teeth, as cut will mesh with other wheels cut on the same machine. The bar 34 is provided with a stop 52 located in one or other of the holes 36 so that by swinging the bar round it can be held in 3 positions as the stop abuts against one or other of the faces a, b, c of the work table 2, Fig. 3. Each notch can then be cut twice, i.e. once at each extreme swing position of the arm 34, so that approximately accurate involute shaped teeth flanks are cut.
