Title: Method of manufacturing a gas discharge display panel
IPC: H01J9/24
Filed: 1972-06-26
Abstract: 1355307 Glass-metal seals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 June 1972 [29 June 1971] 29843/72 Heading C1M [Also in Division H1] Conductor arrays 4 and 5 of a gas discharge display panel are secured to a first plate 1 and/or a light-pervious second plate 2 by glass enamel 6 which has a lower melting point than the material of the corresponding plate. Both plates 1 and 2 may be of window glass. The enamel 6 may cover the edges of the conductors 4 and 5 to prevent discharges occurring between adjacent conductors of the same array. A suspension of the enamel applied either to the conductors or to the plates 1 or 2 is melted when securing the conductor in position. The conductor arrays are preferably formed by photo-chemically etching slots in a metal plate or sheet, e.g. of Fe-Cr-Ni alloy to leave the conductors with their ends connected together by two sides of a rectangular frame formed by the remaining parts of the plate. The two sides of the frame parallel to the conductors are first removed and the conductors placed under tension, e.g. by springs attached to the other two sides of the frame, these sides being removed when the conductors have been secured to the plates.  In a modified construction (Figs. 6 and 7, not shown) the conductors 5 are wires of Fe-Cr of circular cross-section which are each completely covered with a resistive layer, e.g. of semi-conductive glass, which may also be used to secure the wires to the plate 2.

Abstract: 319,957. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 18, 1928. Hydrogen, catalytic production of from mixtures of methane and steam.-In the production of hydrogen by treatment of methane with steam the conditions are regulated so that 2-15 per cent of methane remains in the gas obtained. This methane is subsequently removed either by washing with solvents or by converting it by means of air or oxygen. The carbon monoxide which is formed is removed by converting the greater part of it, by means of steam, into carbon dioxide and removing the latter by means of solvents. Remaining traces of monoxide are then removed by washing with a cuprous salt solution or by reconverting into methane. Alternatively, the reaction product may be purified by washing with liquid nitrogen.

IPC: F02D15/04
Filed: 1922-11-09
Abstract: 210,197. Evans, T. A. Nov. 9, 1922. Cylinders, varying clearance of.-A small cylinder 1 is screwed into the head of the working cylinder; it carries a piston 3, loaded with a spring 6, compressed air trapped in the space 5 which is adjusted in volume by the plug 8, or by both a spring and compressed air. The piston carries a plug 10 which enters an opening 2 with a slight clearance. The effect of this addition to the engine is that at slow speeds the air his time to enter the cylinder during the compression stroke and by rais. ing the piston 3 increases the clearance space and so avoid premature ignition, but at high speeds when the piston reaches its dead centre before ignition can occur the rise of pressure in the cylinder 1 is not rapid enough to raise the piston 3. Several chambers 5 can be connected together and supplied with compressed air by a single pump.

Title: Improvements in or relating to flatwork ironing machines
IPC: D06F67/06
Filed: 1948-11-26
Abstract: 661,119. Ironing-machines. CROOK, C. S. Nov. 26, 1949 [Nov. 26, 1948], No. 30669/48. Class 138 (ii). Means for stripping the ironed work from an ironing roller 10 of a flatwork ironing machine comprises a member whose surface moves in an arc of smaller radius than that of the ironing roller, this member being positively driven so that its linear or peripheral speed is substantially the same as that of the ironing roller and being associated with the latter on the delivery side of the machine so that it exerts pressure on the ironing roller 10 and turns the work away therefrom as it passes between the member and roller after emerging from between the roller and bed 11. In Fig. 1 the smaller radius member comprises a roller 12, while in Fig. 2 it comprises an endless belt 19, and in both cases the member is positively geardriven. In Fig. 1 the stripping roller 12 is mounted in adjustable bearings to vary the contact pressure between the two rollers 10 and 12. Roller 12 may have a radius between one-tenth and one-quarter of that of the ironing roller 10. The work is turned away from the ironing roller by the stripping roller and is conveyed away by a series of endless bands 15 passing side by side over the roller 12 and over another roller 16 at the other end of a metal apron 14. The apron 14 and bands 15 execute a pendulum motion between the positions shown in full and broken lines so as to fold the work in concertina fashion on a table 17. In Fig. 2 the belt 19 is driven by a roller 21 and passes in contact with the'ironing roller 10 over a support or rod 20 of small radius. The belt 19 also passes over a second rod 22, the rods 20, 22 and roller 21 being carried on a carriage 26 which is slidably mounted on brackets 27 secured to the machine. Screw and nut mechanism 29 is provided for moving the carriage 26 towards and away from the roller 10 to vary the pressure between the belt and roller. Further screw and nut mechanism 30 is provided for moving the roller 21 along the carriage 30 to vary the tension of the belt 19 itself.

Abstract: 484,497. Models. BERGER BROS. CO. Nov. 10, 1936, No. 30706. Convention date, July 25. [Class 146 (ii)] [Also in Group XIV] A device for demonstrating posture comprises a twodimensional jointed figure having the profile contour of the human body, and consisting of a chest portion and a pelvic portion, and a member to which the two portions are pivoted, and another member also between the two portions and adjacent the front of the figure and carrying a representation of the abdominal organs, so that the chest and pelvic portions may move towards and away from each other and illustrate collapse and extension of the abdominal portion in different positions. The figure comprises shaped pieces of stiff cardboard 10, 12, 14, 16, 18, 20, 22, 23 pivoted together at 11, 13, 15, 17, 19, 21, 24, and carrying pictures of the skeleton and the intestines. The figure may be pivoted to a flat surface at 24 and connected to a pin by an elastic cord 28, and then normally assumes the upright posture. The abdominal member 16 lies behind the thorax and pelvis 14, 18, so that, when the figure is caused to assume the "fatigue posture" by pressure on the front of the abdomen the consequently smaller visible area of the member 16 illustrates the compression of the intestines. The "lordosis posture" can be obtained by pressing the back of the member 16 thus exposing more of the member 16, and the point at which corrective pressure for each posture must be applied by a corset or girdle can be demonstrated on the figure. In a modification the member 16 may extend only across the back of the figure and its place at the front be taken by an elastic fabric, carrying the picture of the intestines and adapted to be crumpled. or stretched in the "fatigue and lordosis postures," or by an arrangement of telescopic fan-shaped members. The head is connected to the surface by a slot fitting over a pin,

Filed: 1962-08-10
Abstract: 973,674. Reactor period meters. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 10, 1962 [Aug. 11, 1961], No. 30852/62. Heading G1A. [Also in Division G4] A nuclear reactor periodmeter comprises an ionisation chamber, a logarithmic amplifier and a differentiating amplifier, the latter effecting also an auxiliary integration so that its response time varies automatically to be relatively great when the neutron power is low or the period large and relatively small when the neutron power is high or the period short. The output of the logarithmic amplifier is fed to a high-grain amplifier 4 with a differentiating feedback circuit 5, 6. Integration which is a function of reactor period is provided by diodes 7,8, the dynamic resistance of which is lower for rapid voltage changes at the point a than for slow changes. A further integration which depends primarily on the neutron flux is provided by the feedback connection through resistor 10 and capacitor 9. Resistor 10 together with Zener diodes 11 and 12 acts as a voltage divider. When the neutron flux is large, the voltage between points a and b is large, diode 11 conducts and diode 12 operates in the Zener state, to give a low dynamic resistance relative to resistor 10. Substantially no integrating feedback is thus applied through capacitor 9. At lower neutron flux, diode 12 cuts off and the feedback is increased.
