Title: An X-ray Apparatus.
Inventor: HOGAN GEORGE REGINALD
IPC: H05G1/68
Filed: 1916-12-22
Abstract: 111,570. Hogan, G. R., and MacLagan, H. P. Dec. 22, 1916. R÷ntgen-ray tubes.-A valveless tube is connected directly to a current source producing an alternating pressure of symmetrical wave form and only of sufficient magnitude to cause unidirectional current in the tube. The pressures at which the tube becomes conductive in one or both directions vary with its construction; they may be 80,000 volts and 105,000- 110,000 volts respectively. In the tube shown in Fig. 1, the anticathode is a tungsten disk 22 let into the bevelled end of a copper cylinder 21. A separate anode, if provided, is preferably not connected in circuit. The cathode 24 is of aluminium. The current source may be a transformer 2 having its primary winding connected through a regulator R with a rotary converter 3, a motor-generator, or a second transformer, or directly with supply mains. Fig. 4 shows a suitable construction of the transformer 2, Fig. 1. The primary winding 1 is adjacent to the closed laminated core, while the secondary is wound on separate insulating spools 27a spaced apart from each other and from the core. The transformer is preferably immersed in oil.

Title: Reagent distributing and measuring device
IPC: C02F1/68
Filed: 1949-07-12
Abstract: 677,535. Delivering measured quantities of liquids. L' AUXILIAIRE DES CHEMINS DE FER & DE L'INDUSTRIE. July 12; 1949 [Feb. 28, 1949], No. 18406/49. Class 106 (v). A device for delivering a liquid reagent in quantities proportional to the quantity of liquid to be treated comprising a fluidtight chamber 10 provided with an overflow pipe 15 and connected with an air bell 2, the base of which opens into a tank 1 containing the liquid to be treated, is characterised in that the inlet opening for supplying the liquid to be measured out is connected to the fluid-tight chamber 19 by a hydraulic joint which may accommodate a pressure head at least equal to that created in the fluidtight chamber 10 by filling the tank 1 and that ensures the overflow of liquid into an overflow pipe 15 to the tank fluidtight cover. The fluidtight chamber 10 which has a filling tube 12 is connected with the air bell 2 by a U-tube 5, the limb 5b connected with the chamber 10 being provided with a tube 7 open to the atmosphere. On filling the tank 1, liquid enters the air bell 2 through an orifice 3 so that the pressure in the air bell 2 and the U- tube limb 5a is increased. This increase of pressure is transmitted through liquid 6 in the U-tube 5 to the other limb 5b with the consequent closing of the tube 7 by liquid 6. The rise in pressure in the other U-tube limb 5b and the fluid tight chamber 10 causes the rise of reagent in a bell 14 towards the top of the overflow pipe 15. When the U-tube liquid 6 is depressed to the junction of the two limbs 5a, 5b, air bubbles through the liquid 6 from the air bell 2 to the fluidtight chamber 10 thus causing an overflow of reagent through the pipe 15 to the tank 1 in a quantity proportional to the amount of air displaced from the air bell 2. On emptying the tank 1 air passes back to the air bell 2 through the U-tube liquid 6 or a capillary tube 9 which joins the limbs 5a, 5b of the U-tube 5 so that the tube 7 is eventually opened to the atmosphere and syphoning of reagent into the U-tube 5 or the air bell 2 is prevented. In a modification (not shown) a gravity feed tank 17 is arranged above the fluidtight chamber 10 and connected with it by a U-tube forming a hydraulic joint.

Title: Plug valve assemblies
IPC: F16K5/22
Filed: 1973-04-18
Abstract: 1409951 Valves ROCKWELL INTERNATIONAL CORP 18 April 1973 [26 May 1972] 18604/73 Heading F2V A tapered plug valve comprises a plug 17 and integral stem 19 at its smaller end formed of an elastic material such as alloy steel so that should the plug stick in one of its operative positions due, e.g. to the build-up of deposits on the plug face, the increasing torque applied to the plug twists the plug to break the bond. At its larger end, the plug forms a chamber 34 with an end cover 28, which is filled with viscous material to prevent egress of deposits. The plug therefore has limited movement axially in order to break the bond. The viscous material is supplied via an injector 45 and pressurized in a reservoir 64. The pressure of the material may be matched to the line pressure by providing a suitable connection between line and reservoir.

Patent GB-1192271-A (GB)
Title: Key-Operated Teleprinter Systems.
IPC: H04L25/40
Filed: 1968-04-22
Abstract: 1,192,271. Telegraphy. HASLER A.G. 22 April, 1968 [26 April, 1967], No. 18967/68. Heading H4P. A keyboard transmitter has a separate key for each symbol and includes means for automatically inserting case shift signals in to the stream of transmitted characters. On depression of a key To is closed, T1-T5 are selectively closed to represent the character, and T6 is closed if the character is a Figures case character. On closure of To the character represented by T1-T6 is transferred via stores A1-A6 and B1-B6 to store C1-C6. Two further characters can be stored in A1-A6 and B1-B6, whereupon electromagnet Ms is energized to prevent further key operation. When Co is at 1 (i.e. when a character is in C1-C6) a time base unit I generates successive pulses t 1 -t 7 . During t 1  the character in C1-C6 is passed to store S1-S6, the characters in A1-A6 and B1-B6 passed to B1-B6 and C1-C6 respectively, and start polarity applied to the transmission line L. During t 2 -t 6  the content of S1-S5 is passed serially to line, and during t 7  Stop polarity is applied to the line. Subsequently stored characters are transmitted in the same way. When no character is to be transmitted the line is held at Stop polarity. The case bit (from T6) stored in S6 of a character to be transmitted from S1-S5 is passed to store K, and any change in state of K, indicating that the character to be transmitted is not in the same case as the character just transmitted, causes H to prevent read out of S1-S5 and a LTRS or FIGS character as appropriate to be automatically transmitted by way of gates UL2, 3, 5, 6. Should C1-C5 contain a character which has the same significance in either case (e.g. Carriage Return) store S6 is prevented from changing state when the character in C1-C5 is passed to S1-S5, and consequently no case shift character is inserted prior to transmission of this character. Repetition of a character is initiated by closure of T7. This sets W to inhibit gate UZ so that read out from C1-C6 to S1-S6 is prevented. Time base 1 now generates t 1 -t 7  continuously and the character in S1-S6 is passed to line repeatedly until T7 is released.

Abstract: 1435317 Treating exhaust gas EXXON RESEARCH & ENG CO 24 April 1973 [24 April 1972] 19289/73 Heading C1A [Also in Division F4] A method of treating exhaust gas containing NO x  and other contaminants comprises the steps of contacting the gas, in the presence of oxygen with a compound selected from the group containing hydrocarbons, oxygen-containing hydrocarbons, nitrogen containing hydrocarbons, halogen containing hydrocarbons or sulphur containing hydrocarbons, at a temperature of 400‹ to 2700‹ C., to reduce the NO x  to nitrogen. The treated gas is then contacted with oxygen to oxidize excess hydrocarbon, CO and other oxidizable contaminants. Exhaust gas from an engine 10 having an exhaust valve 13 flows along a tube 18, to which fuel and air are metered by a carburettor 26. Additional air is injected near the downstream of pipe 18 for the oxidation step. The heated gases return along the outside of tube 18 in heat exchange relationship therewith and leave by a port 22 leading to a silencer. In a modification fuel is injected, into the flue gases of a boiler burner, through a water cooled probe and air is injected downstream of the probe for the second reaction. Two ratios are critical for optimum reduction of NO they are (a) C ¸ NO x  where C is the total number of carbon atoms per mole of NO, supplied by the hydrocarbon C n H m  where n is 1 to 12 and m the integer corresponding to an existing compound, and (b) the ratio O 2  ¸ C, which is the quotient of O 2 ¸ NO and C ¸ NO. When there is no oxygen in the exhaust gas C ¸ NO x  is 0À02-400, preferably 4 : 1 to 70 : 1. The ratio O 2  ¸ C can vary between 0À01 and 12, preferably 0À25 to 1À0 with optimum performance between 0À5 and 0À8. The most preferred reaction temperature is 700- 1450‹ C. and the residence time is 25-300 milliseconds, preferably 100-250 milliseconds. Self-contained reductant mode.-If hydrocarbon and air are supplied for a comparatively short time, e.g. 10 mins, reduction of NO continues for several hours, due to the deposition of the reductant on the reactor walls.
