Title: Improvements in methods of treating and coating ferrous metal bodies, and the resulting products
IPC: C25F3/06
Filed: 1925-06-29
Abstract: 236,241. Madsenell Corporation, (Assignees of Knauss, F. V.). June 27, 1924. [Convention date]. Void [Published under Sect. 91 of the Act]. Pickling; tinning, galvanizing, and coating by dipping. - Ferrous metal objects such as steel sheets are treated to remove surface carbon or occluded hydrogen or other gas, preferably both carbon and gas being removed. The object is first treated with hot caustic soda or other alkali to remove grease, and after rinsing in hot or cold water is pickled in dilute hydrochloric or sulphuric acid. It is then rinsed, if an acid other than sulphuric has been used for pickling, and treated as anode in a bath of strong sulphuric acid, preferably above 84.5 per cent strength. The cathode may be of lead or of iron or steel covered with lead, or of iron or steel. A series resistance about five times that of the cell is employed. The current density is preferably 20 amps. per sq. ft. of anode surface, but 5 amps. per sq. ft. or less may be used. The treatment is continued until the current falls to a constant value about one-fifth or lees of the initial current. The temperature should be about 100‹ F. Hollow bodies are treated by filling with acid and inserting the cathode therein. The acid need not completely fill the body provided the body be rotated so that the whole of the interior surface receives treatment. The body should be rinsed after treatment. The properties of the treated articles are rendered more permanent by treatment with sodium carbonate or other alkaline solution. This may be allowed to dry on and then acts as a flux for coating metal such as lead, tin, or zinc, which may be applied by dipping, spraying, or flowing. Non-metallic coating materials such as paint, vitreous enamel, or baking enamel may alternatively be applied to the treated iron or steel.

Title: Improvements in and relating to strip or band feeding devices for machines
IPC: B31B50/10
Filed: 1962-05-04
Abstract: 1,006,670. Feeding webs. H. C. LARRIEU. May 4, 1962 [May 6, 1961], No. 17124/62. Heading B6B. Mechanism for feeding strip material 32, Fig. 1, step-by-step through e.g. a metal-cap forming machine, includes a device for clamping the strip in registered position, which device is operated pneumatically when perforations in the strip register with suction ports associated with the device. The mechanism comprises a feed roller 5 having suction ports 17, Fig. 4, on its periphery whereby the strip is gripped and fed forward during a part of each cycle of the machine. The feed roller 5, driven in synchronism with the machine, is mounted between plates 7, 8, Fig. 3, fixed to plates 2, 3 secured to the frame 1 of the machine. Suction ports 17 on the periphery of the roller communicate by means of passages 19, 18 in the roller with a groove 20 in the plate 7. Suction is applied to the groove 20 through an orifice 16 so that during most of the period the passage 18 is in communication with the groove 20 and suction is being applied to the ports 17, the web 32 is fed forward by the roller 5. At the latter end of that period, however, the web is held by the clamping device as described below and the ports 17 slip over its surface. The clamping means comprises an adjustably-fixed block 21, Figs. 1, 2 over the surface of which the web passes, and having side guides 22. Between the guides 22, a freely slidable block 33 is mounted, and rests on the web. The block 33 has a cavity 36 on its lower face. Passages 31 in the lower block 21 communicate by means of a passage 29 with a passage 15 in the plate 7 communicating with a groove 14 in the roller 5 at certain angular positions of the roller. Another passage 13 in the plate 7 is connected to suction and also opens into the groove 14 at certain angular positions of the roller 5. After the web has been fed a certain distance, suction is applied to the passages 31 through passages 13, 14, 15, 29 and causes braking of the web without stopping its feed. When, however, perforations 43, Fig. 5 (not shown) in the web, situated between printed designs, register with the passages 31, suction is admitted to the cavity 36 in the block 33 drawing the block downwards so that the web is clamped between the blocks and feed prevented whilst the passage 13 communicates with the groove 14. The clamping lasts until beyond the period during which the ports 17 act on the web. Stationary guides.-The web is guided over the roller 5 by a member 37, Fig. 1, and is stripped therefrom by a member 39 engaging a groove 38 in the roller.

Filed: 1957-05-31
Abstract: 831,293. Typewriters. INTERNATIONAL COMPUTERS & TABULATORS Ltd. April 15, 1958 [May 31, 1957], No 17372/57. Class 100(4) [Also in Group XXXV] A continously rotating Johnson-Rahbek pulley is caused to drive a metal band 9 for operating a stylus 2 or a paper-feed clutch or other components, by the discharge of energy from the dielectric cylinder 15 to the adr-gap capacitance between the cylinder and band 9 by a reduction in the applied potential. When not in operation, the cylinder and band are steadily excited from a D.C. source, but when required to operate, a signal from a source 8 renders a triode 21 conducting thus producing a voltage drop across a resistor or choke 20. This drop in applied potential throws the potential stored in the dielectric 15 across the effective air - gap caused by surface irregularities between the dielectric and the band and so causes adhesion. A cable-operated switch may replace the triode when the device is used for setting the bars of a punch card unit or for operating the punches. In certain circumstances a single triode connected in series with the supply line as a normally conducting cathode follower may replace both the impedance 20 and triode 21. If desired both a cathode follower and, triode 21 may be used. Specification 707,736 is referred to.

Title: Improvements in and relating to apparatus for testing by x-ray ionization
IPC: G01N23/16
Filed: 1943-10-25
Abstract: 567,280. Resistance measurements; determining physical qualities and dimensions of materials. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Oct. 25, 1943, No. 17512. [Class 37] The thickness of steel plates, flaws in metal, the chemical composition of liquids, &c. are determined by measuring the degree of ionization produced by X-rays as modified by the material to be treated. Gases may be tested by measuring the extent of their ionization when subjected to X-rays: An X-ray tube 10 is energized from a source 11 and is adjustable by a variable voltage transformer 12. An adjustable shutter 13, which may be of lead, enables the exposure area of the X-ray beam 14 to be varied. The X-rays pass through the plate 18 to be tested and a standard plate 17 to ionization chambers 15, 16, the walls of which may be of lead-lined steel with the upper sides of sheet aluminium to permit passage of the X-rays. The chambers are filled with an ionizing gas such as air or carbon tetrachloride gas. The chambers may be filled with air and the bottom of the chamber moistened with carbon tetrachloride. The ionization chambers are provided with interleaved electrodes 20, 21, 22, 23, which may be of stiff paper painted with a conducting coating. The chambers 15, 16 are connected in series across a resistance 24 and batteries 25, 26, the centre point of the batteries being earthed. A slider 28 on the resistance 24 is connected to earth through a resistance 27. A portion of the voltage across this resistance is amplified by an amplifier 29, the output of which operates a sensitive measuring instrument 30. This may be provided with alarm contacts so as to operate a relay 31 or an alarm 32. With similar plates 17, 18 equal ionization occurs in the chambers 15, 16 and the bridge is balanced by adjustment of the slider 28. The plate 18. under test is then inserted and the instrument 30 indicates the deviation in thickness from the standard plate 17. The plate 18 may be a continuous strip which is moved across the testing position on rollers 33. A weld containing voids may be detected by increased passage of X-rays through it. The chambers 15, 16 are provided with valved pipes 37 by which the gas therein may be changed or varied. One chamber contains a standard gas and a gas to be tested is caused to flow through the other. The composition of flue gases &c. may thus be determined, the plates 17, 18 being removed to increase the sensitivity. Liquids may similarly be tested to determine the percentage of acid or salt.
