Title: Improvements in the phosphate coating of metals
IPC: C23C22/10
Filed: 1952-06-30
Abstract: Phosphate coatings are formed on metal surfaces by the use of a solution of an orthophosphate, other than phosphoric acid alone, which solution contains either no metal or a metal which does not itself enter the coating and at most only small amounts of a metal which does enter the coating, the solution also containing an oxidizing accelerator and one or more phosphates less highly hydrated than the orthophosphate being added to the solution. Orthophosphates of sodium, potassium, magnesium, ammonium or organic bases such as triethanolamine, guanyl urea and pyridine may be used; the accelerator may be a chlorate, nitrite, nitrate, sulphite, hydroxylamine, an oxy-acid of vanadium, chromium or molybdenum, a halogen oxy-acid, m-nitrobenzene sulphonic acid, o-nitrochlorbenzene-p-sulphonic acid, 3-nitrophthalic acid, nitrophenol, m-nitrobenzoic acid, nitrobenzene or m-nitrotoluene or salts of the various acids; and the other phosphate may be a pyrophosphate, a metaphosphate or a polyphosphate.  The solution may also comprise surface-active agents such as sulphonates or organic compounds containing nitrogen-bound polyether groups or oxyethylated higher alcohols.  After treatment, the surface, which may be of iron, steel, zinc, aluminium or their alloys, may be rinsed and further treated with a dilute solution of chromic, phosphoric or oxalic acid or their salts.  Specification 517,049 is referred to.

Title: Improvements in or relating to cash registers
IPC: G06C7/10
Filed: 1937-06-14
Abstract: 497,154. Cash registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 14, 1937, No. 16481. Convention date, June 26, 1936. [Class 100 (iv)] [Also in Group XIX] Locking-devices.-In a key-set cash register the item typewheels 88, Fig. 6, are carried by a shaft 94 slidable in vertical guide slots to enable the wheels to be raised towards a stationary platen 11. This is effected by the clerks' keys, depression of either of which rocks an associated lever 103, Fig. 9. A cam slot 113 in the upper arm of the rocked lever co-operates with a pin 112 to rock a shaft 108, thus through arms 109, Fig. 6, raising the type-wheels to impress the record strip. The type-wheels for the amounts and transactions are set by differential sectors 79. The clerks' type-wheel is normally in position to print the character " B," but is rocked upon the depression of the A " clerks' key through a lever 97 connected to the lever 103 associated with that key. The record strip 115 passes from a supply roll 179<1>, under the platen 111, to a storage roll 184 advanced step-by-step by the operating bar. An inkribbon 116 carried by reversing spools 185, 191 passes over the record strip and beneath the platen. To facilitate access to the record strip, the platen and ink-ribbon are carried by a frame 175, Fig. 6, hinged on studs 177 but normally held in the position shown by a latch. Lifting the frame locks totalizer wheels 121A, 121B by holding aligning bails 240 in engagement therewith. Upon the depression of a total key followed by the depression of the operating bar, the lever 103, Fig. 9, associated with the total key, is rocked, and a cam segment rigid therewith shifts both totalizers outwardly to impress the record strip against platens 180, Fig. 6, carried by the frame 175. To enable the totals thus printed to become visible under a transparent plate, the strip is advanced by a knob on the spindle of the storage roll. This mechanism forms the subject-matter of Specification 497,308.

Filed: 1930-05-28
Abstract: 355,746. Automatic exchange systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, and BEALE, C. E., 59, Towers Road, Wavertree, both in Liverpool. May 28, 1930, No. 16512. [Class 40 (iv).] A mechanical order wire is installed between a private branch exchange and a main automatic unit and the apparatus at the main exchange, which is common to several PBX's, responds to impulses of one type and transmits impulses of another. To originate a call the opeiator operates key KTK and plugs into the jack JJ. energizing CO which disconnects L, Relay ST pulls up and KT energizes, locks to RK, extends the operator's key set OKS to the outgoing keying trunk and lights supervisory lamp SLP. Relay ST releases slowly when KT pulls up and, during the slow period of ST, battery is'extended over SPK tip of plug and conductor 13 to operate IL. Relay IL energizes B and completes a loop to initiate the operation of the lineswitch associated with the circuit. Over wiper 1b of preselector DD, relay B starts the junction finder JFS hunting for the calling circuit which is marked by battery over KS. When the circuit is reached, KS energizes extending the keying trunk to a sender, extending the sender impulsing circuit from wipers 2a, 3a of JFS to the switches and returning dial tone over TC to the caller. The sender is common to several private branch exchanges, and may be of the type described in Specification 315,735, [Class 40 (iv), Telephones &c.], except that it responds to the code as well as the numerical digits of the subscriber's number. The code may be translated or may be transmitted from the sender to a register-controller. When the operator receives dial tone, the wanted number is set up on the key set and the digits are transferred in code to the sender. When the full number of digits have been received FR energizes, locks to the release conductor, disconnects the keying trunk and releases IL. Relay B falls away,' KK releases and SC de-energizes and, during the slow period of SC, relay TR is energized to release KT and the outgoing end of the keying trunk. Relay KT can also be released by operating the key RK. When the sender has transmitted all the digits KS releases, switching through the speaking conductors. On an incoming call when the junction is seized FR energizes removing IL from the circuit and energizing L to light the call lamp CLP. When the operator plugs into the circuit, ringing is tripped and CO energizes to disconnect L and extinguish the calling lamp. For night service key NSK is operated energizing NS. Relay NS has armatures shorting the contacts of FR connected with every night service exchange line, resulting when NS is energized in the lines being switched through direct from the PBX to the automatic switches.

Title: Improvements relating to the removal of hydrogen sulphide from hydrocarbons
Inventor: NICKLIN THOMAS
IPC: C10G27/12
Filed: 1959-05-14
Abstract: Hydrogen sulphide is removed from liquid hydrocarbons, e.g from hydrofined oil, middle distillate oil, or benzole, by contacting the oil with an aqueous alkaline solution of one or more isomeric anthraquinone disulphonic acids the resulting reduced anthraquinone disulphonic acids being subsequently reoxidized with oxygen, or with a gas containing oxygen, e.g. air. The pH of the treating solution is adjusted to more than 7, and preferably to 8.5-9.5 by using ammonia, caustic soda or potash, sodium, potassium or ammonium carbonates or bicarbonates, or alkanolamines as the alkali; final adjustment of the pH is effected by means of boric or acetic acid.  The treating process may be performed either co-currently with turbulent flow or counter-currently through a scrubber.  The reduced treating solution is reoxidized with air either in the upper region of the treating chamber when the treatment is co-current, or in another separate chamber when the treatment is counter-current and then recycled to the treating chamber.  The liberated sulphur is removed by filtration either before or after regeneration of the anthraquinone disulphonic acids.  According to the Provisional Specification, any organic compound containing a readily reducible carbonyl group, such as Indigo Carmine may be used instead of anthraquinone disulphonic acid.

Abstract: 737,863. Digital electrical calculating apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 21, 1950 [June 22, 1949], No. 16590/49. Class 106 (1). An electronic digital computing machine comprises a first data word storage device, a computing organ, and a control system for controlling the operating rhythm of the machine and ordering the necessary transference of number and instruction words to perform a computation, which also includes means for obtaining an automatically checked answer word by repeated performance of the same computation until two identical answer number words are obtained as the results from separate performances of such computation. In the described embodiment a series-mode type of machine employing the binary system of notation comprises a magnetic memory device 9, Fig. 1, in addition to C.R.T. storage devices T00, T01, &c. The output of a selected C.R.T. appearing at a buffer circuit 5 is applied to a comparing device 15 as X, while the contents of a selected magnetic track appearing at the output of a reading unit 11 is applied through a cathode follower 14 as Y to the comparing device. If the signals are not identical a non-check signal is passed to a trigger 16 turning it on, and this causes a further check to be made by adding one to the control instruction in the control tube of the machine. When the check trigger is reset by a device 22 a binary counter 17 is operated; this counter, by means of neons 18, indicates the number of " non-check " signals received and also controls a device 20 to stop the machine if a predetermined number of non-check results are registered. The comparing device operates on the principle that if two binary digits are not equal their sum must be 1. Specifications 657,591, 705,479, 707,634, 707,635, 731,341 and 737,864 are referred to.
