Abstract: 1498161 Temperature responsive actuating elements BRAUKMANN ARMATUREN AG 25 April 1975 [26 April 1974] 17283/75 Heading G1D [Also in Divisions F2 and H1] An actuating mechanism for a thermostatically controlled displacement member, e.g. the stem of a heating valve, comprises a first housing 2, a spring-loaded lever 1 pivotally mounted in the first housing 2, and a thermally sensitive control element 14 pivotally mounted on the lever 1 and comprising a work member 19 which remains stationary with respect to the first housing 2, and a second housing enclosing thermally expandable material. As described, the stem of a valve may be connected to displacement member 26. Two switches 23, (25), Fig. 2 (not shown) may be mounted on the lever 1, switch 23 co-operating with a stationary switch member to activate a coil heating element 17 situated around element 14, switch (25) actuating a pump of a heating installation. The element 14 may be mounted on a pivot plate 12 which has two trunnions 21 mounted in bearing shells 22 on the lever 1. The pivot plate 12 is arranged between prongs of a bifurcated end of the lever 1, and may have an abutment 35 which co-operates with an adjacent surface of the lever 1 so as to limit pivotal movement of the plate 12. A manually operated eccentric 32 may be provided to pivot the lever to raise member 26 and hence the valve stem or other displacement element connected thereto. The switches 23, (25) may be mounted on the housing 31, the switch abutment members being on the lever. Loading spring 6 may be replaced by a tension spring actuating on the upper side of the lever. A one arm lever may alternatively be provided with a tension or compression spring on the upper or lower side of the arm.

Title: Method and apparatus for atomizing liquids
IPC: F23C99/00
Filed: 1956-06-06
Abstract: 832,772. Liquid fuel burners. COLIN-SMITH, E. June 6, 1956, No. 17521/56. Class 75(1) [Also in Group XXIX] A method of atomizing liquids comprises first impinging liquid with high pressure air streams to break up a liquid column into air separated particles, whilst the liquid is constrained to flow in a column, expanding the liquid and air column through an orifice and through an annular convergent high pressure air stream to effect separation of the liquid particles and control of the expansion of the air separated liquid flow, then expanding the resulting liquid particle and air mixture through an orifice into an annular convergent low pressure high volume air stream to effect further liquid particle separation and to direct air against and to support air envelopes around the liquid particles and then releasing the enveloped particles through an orifice for further expansion. Oil fed under pressure from a pipe 49 to a duct 33 is atomized bv air which is at a pressure greater than the oil pressure and fed from an inlet 60 to a chamber 25 and through a pipe 35 to pass partly as a number of jets into the oil stream through a number of fluted holes 42 in a conical nose portion 41 and partly around the oil and air stream issuing from the nose portion 41 through an annular passage formed between the nose portion 41 and a conical portion 38 of a nozzle 36. The atomized oil and air mixture then passes through an orifice 37 in the nozzle 36 where it is mixed with a high volume of low pressure air fed to a chamber 11 by a duct 61 to pass through an annular passage formed between the nozzle 36 and a convergent portion 17 of a member 16, the resulting mixture passing through an orifice 18 into the combustion zone 7. The chamber 11 is formed in a casing 10 slidably mounted on rods 9' by sleeves 14 formed on arms 13. The member 16 is adjustably screwed on the forward end of the casing 10 and has an annular flange 20 slidably engaged in the smaller end of a frusto-conical member 21 the larger end of which is slidably mounted in an annular flange 5 of a ring 1 securing the burner to the furnace wall 3. The duct 33 is screwed into a block 30 axially adjustable by means of a collar 27, rotatably held on the block 30 by a nut 34, adjustably screwed on a block 24. The fuel supply is controlled by a valve spindle 51 provided at its forward end. with a conical surface 53 which engages a conical seat 48 and with a stem 54 having a V- notch 55 cut in its end. The nose portion 41 is formed on a tube 39 slidably mounted in a spider 40 located in the nozzle 36. The chamber in front of the valve seat 48 can be purged of oil by passing compressed air thereto. Steam or air containing water vapour can be used in lieu of compressed dry air.

Abstract: 1380159 Digital transmission; dialling discrimiriation at exchanges COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 19 April 1972 [19 April 1971] 18091/72 Heading H4P An arrangement, particularly for use in international telegraphic exchanges to discriminate between manual/auto (decimal) dialling and arrythmix (telegraph code), addresses comprises a circuit initially set for reception of arithmetic signals which is switched on reception of decimal dialling by testing incoming signals at determined times on order to establish polarity at these times. Element EL indicates +Ve states of line L on wire LP and - Ve on wire LM. Receiver R distributes each bit of a first letter received in telegraphic modulation on wires f1-f5 which are memorized at BM, the first 4 being indicated on wires M1-M4. At the end of reception, wire CL is marked to cause discriminator to inspect wires LP, LM. If the discriminator finds decimal reception, a control signal over wire DC causes element AI to inhibit selection of arrythmic reception and to enable decimal reception. Element OD marks one of the wires MAN for manual or AUT for auto dialling or EF for reset or fault.  A circuit is described in connection with Figs. 2 and 3 (not shown), for distinguishing between the various types of address signals.
Patent GB-181324-A (GB)
Abstract: 181,324. Meyer-Keller et Cie, O. June 9, 1921, [Convention date]. Heating by electricity.-In apparatus for heating liquids by electrodes in which the liquid forms the heating-resistance, regulation is effected by altering the sectional area of the conduit formed by the insulating case, the latter being divided longitudinally and the parts adjusted for this purpose. The electrode b, Fig. 1, is carried by an insulating rod a and is placed between two insulators c, d, which can be adjusted to vary the space between them. In a modification, the insulators are inclined to the electrode providing a greater space at the top than at the bottom. The electrode may be arranged horizontally instead of vertically in the boiler. The insulator may be in three parts n, o, o. Fig. 12, one of which, n, is movable relatively to the others. When three electrodes are used, one set of insulators s, Fig. 13, is fixed, and the other sets r are carried by arms on a spindle t, which can be rotated to adjust simultaneously the space around each electrode b As installed in a vertical boiler, Fig. 10, regulation of a single electrode may be effected by altering the level of liquid. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification wherein the electrode b is wedge shaped, Fig. 14 (Cancelled), and the inclined insulators e<1>, f<1> are carried by a bridge piece h adjustable vertically by the rods h<1>.

Title: Improvements in the manufacture of alkali metal phosphates
Inventor: EDWARDS ROBERT HARRY
IPC: C01B25/30
Filed: 1964-05-04
Abstract: Alkali metal phosphates (e.g. sodium phosphate) are produced from wet process phosphoric acid by neutralizing the acid in a known manner, filtering the neutralized liquor, maintaining the filtrate at least at 60 DEG  C. for at least 2 hours to precipitate residual Ca, Mg and Fe, filtering a second time, and evaporating the filtrate to obtain a dry solid product.  The filtrate from the second filtration may be evaporated to concentrate it and filtered again before being evaporated to dryness.  After the first filtration, chlorine or an alkali metal hypochlorite may be added to the neutralized acid before it is evaporated to dryness. Nitric acid or a metal nitrate may be added to the liquor before or after the first filtration.  The amount of chlorine or hypochlorite added is preferably such that the redox potential of the liquor is at least 500 m.v. measured using a Pt electrode and a calomel reference electrode, or alternatively the liquor may contain about 1% by weight of chlorine or hypochlorite calculated as NaOCl on the P2O5 in the liquor.  The dried solid product obtained may be calcined to produce tripolyphosphate.
