Title: Process for the treatment of boiler feed water
Inventor: GRAY JOHN ALAN
IPC: C02F5/02
Filed: 1954-12-20
Abstract: In the known alkaline treatment processes (defined in the Specification) given to boiler feed waters and boiler waters, the resulting boiler sludges are rendered free-flowing by adding a readily-soluble magnesium compound to the boiler feed water in such amount that the value of the expression:  <FORM:0784750/I/1> in which CaO, MgO, SiO2 are respectively the equivalents in moles of the calcium, magnesium and silicon compounds in the boiler feed water, is greater than 4 and preferably greater than 7.  The treatment according to the invention may be provided by continuously feeding magnesium sulphate (or nitrate, carbonate or chloride) solution into a boiler feed water vessel, or directly into the boiler, or into the feed water before it enters the boiler, so that in any case precipitation of sludge occurs in the boiler.  Alternatively, briquettes of magnesium sulphate may be packed into a by-pass feeder for gradual solution as feed water passes over them.  One or more of the following may be present in the feed water or boiler: an antifoaming agent (e.g. selected from polyoxyalkylene glycols, monoethers and diethers of polyoxyalkylene glycols, polyacyl polyamines), a de-oxygenating agent (e.g., sodium sulphite, sodium nitrite, tannins, hydrazine), sodium aluminate.  According to the first Provisional Specification the "formula expression" is: <FORM:0784750/I/2> and the alumina content of the feed water may be adjusted by addition of sodium aluminate.

Title: Circuit Arrangement for Receiving Key-Controlled Selecting Information in Telephone or Telegraph Exchanges
Inventor: SCHUBERTH WINFRIED
IPC: H04Q1/38
Filed: 1967-08-11
Abstract: 1,189,454. Exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 11 Aug., 1967, No. 36915/67. Heading H4K. Equipment at a telephone or telegraph exchange for responding to key-sent digital signals consisting of a ground connection to either or both line wires through a resistor, R 1 , R 2  with or without a rectifier D1-D4, is powered by a stabilized voltage source separate from the normal exchange battery and of greater voltage. Such source may be a converter fed from the exchange battery. As shown, selection is made in two stages by two pairs of relays A, B and C, D, the former operated by a capacitor CA charged by the separate voltage source Uabfr, the latter (C, D) operated directly thereby. Provision is made for sending and receiving an end-of-selection signal with the aid of relay WE. The provision of a very high testing voltage allows current limiting resistors R1, R2 to be retained in the sub-set without any ambiguous operation of the relays A-B due to induced voltages in the line. In a PBX, retention of the resistors is of importance because operation of special function keys, e.g. ST 1 , ET is easily distinguished by the digit receiver due to the increased current level in one or both line wires.

Title: Improvements relating to guide wheels for rail vehicles
IPC: B61F5/38
Filed: 1930-12-10
Abstract: 357,872. Tramway and vehicle undercarriages. DUNLOP, S., 49, Chancery Lane, London.-(S³ddeutsche Eisenbahn- Ges. ; 34, Zweigertstrasse, Essen, Germany.) Dec. 10, 1930, No. 37249. [Class 103 (vi).] The wheels of a tramcar or like rail vehicle are mounted in individual swivelling frames R and, in order to obviate any shortening of gauge measured at right-angles to the planes of the wheels when the vehicle traverses a curve, each wheel frame is adapted to pivot optionally about one or other of two symmetrically disposed axes P1, P2 or P3, P4, the appropriate pivot being selected automatically while each pair of wheel frames is coupled together so as to maintain their parallelism. In the associated wheel frames shown, for example, if the vehicle is travelling in the direction of the arrow and encounters a right-hand curve, the right wheel frame will swivel about the pivot P4 and the left hand frame about the pivot Pl. The four pivots are linked by means of rods D having telescopic ends to the intermediate members T of a truck frame A, T1 so that, in normal running on a straight track, the telescopic parts are in a shortened condition, while on a curve, two diametrically opposed telescopic parts are lengthened. The connection between associated wheel frames comprises linkages V1, V2, Fig. 2, pivoted to the truck frame at points O1, 02, which in actual practice constitute a single pivot, and having interposed between the points W1, W2 a dashpot regulated spring F3 which is tensioned when the linkages are displaced and thus assists in restoring the parts to their normal position. The wheels themselves are mounted on members G resiliently supported on the frames R through springs F2, while further springs F1 are disposed between the vehicle body and truck frame. Three tracks B on the truck frame co-operate with rollers on each wheel frame for controlling the swivelling movements of the latter.

Abstract: 969,123. Switching systems for mechanical devices. SPERRY RAND CORPORATION. Oct. 2, 1962 [Oct. 11, 1961], No. 37332/62. Heading H2H. A circuit for actuating alternately one of a pair of loads 36, 43 at a high initial and subsequent lower rate comprises an energy storage means such as a capacitor e.g. 33 normally charging through a solid state switch 30 which is blocked when a terminal 10 receives a control signal. This also renders a transistor 39 conductive thus discharging the capacitor 33 until its potential drops to that at terminal 34 from which the load 36 is then supplied at a lower rate. The signal at terminal 10 also renders a transistor 21 conductive, thus charging another capacitor 42 which energizes a load 43 when a signal is applied to terminal 10a.

As shown, the bolt 7 is kept in the released position by the eccentric portion 11 of the cam 10 and when the plug 3 is rotated by the key 20 the catch member 9 abuts the projection 6 on the cover-plate 5 to prevent the bolt being moved by the spring 14 to the locking position. Withdrawal of the key entrains the plug and cover-plate axially away from the cam due to coupling of the spring- loaded tumbler 15 and the key and projection disengages from the catch member to allow the bolt to move to the locking position; the tumbler, due to axial movement of the plug, becomes positioned in the grooves 18 of the shell 2. Insertion of the key into the plug causes the tumbler to assume the position shown in the figure and the plug to be moved axially by the spring 21, and rotation of the key causes the catch member 9 to ride over the projection 6, the cam being rotated to withdraw the bolt. The plug 3 and cover 5 may be formed as a single element, or the plug 3 may be of two parts axially movable with respect to each other.

Abstract: 792,434. Flexible hoses. HOOVER, Ltd. Dec. 30, 1955 [Jan. 26, 1955], No. 37515/55. Class 99(2). In a hose comprising a resilient, helical reinforcing coil 12, e.g., consisting of wire 14 sheathed in thermoplastic material 13, and a tube 11 of elastomeric material formed with inwardly and outwardly opening, helical corrugations 15, 17, the turns of the coil lying in the corrugation 15, the depth of thecorrugation varies gradually and progressively throughout at least a portion of the length of the hose. As shown, the corrugation containing the coil, in the normal relaxed condition of the hose, embraces the turns of the coil around at least half the circumference thereof, and is not bonded to the coil. The hose is made by freely suspending the coil about a vertically disposed, expansible mandrel, so that the turns of the coil at the top thereof are more widely spaced apart than those at the bottom, and the mandrel is expanded by fluid pressure into engagement with the coil, the tube 11 being inflated and passed over the coil and then allowed to contract. The mandrel is collapsed to release the coil which contracts longitudinally to initiate corrugations in the tube. Finally, the hose is immersed in hot water at a temperature between 165F. and 180F. to soften the tube and relieve the stresses therein, thus allowing the turns of the coil to close up towards one another and complete the formation of the corrugations. Specification 784,060 is referred to.
