Title: Improvements in and relating to belt load weighing apparatus
IPC: G01G11/04
Filed: 1953-08-17
Abstract: 738,353. Electric indicating systems. HARTSHORN, S. D. Aug. 17, 1953, No. 22584/53. Class 40 (1). The load carried by a travelling belt is measuring by a resistance strain gauge supporting a pivotal carriage having rollers over which the belt passes. As shown, the upper run of the conveyer belt 10 passes over rollers 21, 20 carried on a rockable carriage 19 pivoted at 17 to brackets 18 carried by longitudinal frame members 15. The carriage 19 is also supported by a strain-sensitive device 26 on a cross-frame member 25. The strainsensitive device may alternatively be arranged to be tensioned by the conveyer load. The carriage 19 may also carry troughing rollers 29 and its pivotal axis 17 is arranged, by using various brackets 18, in line with the centre of gravity of the load. The carriage may also be counterbalanced by weights at its righthand end corresponding to the belt tare. The lower run of the belt drives a tachometer generator through a pulley 36. Circuitry. The load-sensing device 26 carries strain gauges 50, 51, Fig. 3, arranged in opposite arms of a bridge fed from the belt driven tachogenerator 35. Zero adjustment of the bridge is effected through an adjustable resistor 41. The bridge output may be fed to a watt-hour meter for integrating the load over a period or may be indicated and recorded by means of an automatically-balanced potentiometer. Two weighing stations may be used, separated by a point at which the belt is loaded, the difference between the two loadings being indicated or recorded by connecting the respective bridge outputs differentially to the meter.

Abstract: 1,025,780. Track lifters. MANNIX INTERNATIONAL Inc. June 1, 1964 [June 3, 1963(2)], No. 22620/64. Heading E1G. Track gripping means comprises a plurality of groups 40, 41, 42 of rail gripping rollers each group comprising a plurality of rollers 50 of which at least one of each group is positioned on each side of a rail structure, each roller being flanged at 50a to engage the underside of a rail head and there being means for independently moving any group into and out of rail engagement. Pairs of roller groups 42 are secured to a transverse frame 20 movable laterally by screw and nut mechanism 34 and motor 31, relative to a transverse beam 22 pivotally mounted on vertically adjustable columns 25 and hydraulic jack 27. The columns and jacks are supported on a boom 10 carried by rail mounted trucks to provide a track lifting apparatus. Flexible feelers at each end of each roller group actuate sensing mechanism 51 on touching a fishplate 70 to actuate an hydraulic ram 63 which extends to pivot the rollers 50 about axes 56 to a rail disengaged position. Further movement of the boom along the track to clear both feelers of one group from the fishplate results in the rollers of that group being moved back into track engaging condition. In the embodiment of Fig. 2 the centre groups of rollers 41 are set higher than the end groups 40, 42 to compensate for rail curvature when raised. In another embodiment, two sets of roller groups are employed, with hydraulic jacks for transverse rail slewing movement and flanged rollers for fishplate sensing.

Title: Improvements in the production of titanium pigments
IPC: C01G23/053
Filed: 1939-08-05
Abstract: 533,227. Titanium oxide. NATIONAL TITANIUM PIGMENTS, Ltd. (Verein fur Chemische und Metallurgische Produktion). Aug. 5, 1939, No. 22735. [Class 1 (iii)] Titanium oxide which after calcination has a rutile structure is made by hydrolysis of titanium sulphate by means of "seeds" of oxide or hydroxide of a metal of the fourth group of the periodic system wherein the seeds are made by precipitating the oxide or hydroxide from a salt solution by adding an alkaline reagent, freeing the precipitate from sulphate ions if present, and peptizing the precipitate by warming with a strong mineral acid other than sulphuric acid. Before use the peptized seeds may be coagulated by alkali, washed free from electrolytes, and used as a sol or gel. Preferably the hydrolysis and the production of the seeds take place in the presence of phosphoric acid or a phosphate. The seeds .may be produced from a part of a titanium sulphate solution to be hydrolysed by adding an alkali until the pH is about 3-6, washing thoroughly and peptizing with hydrochloric acid. In an example, a solution of ilmenite in sulphuric acid containing 1 per cent. of phosphoric acid is treated with caustic soda to pH 3-6; the precipitate is washed and stirred with hydrochloric acid at 90‹C. The product is then added to the original titanium sulphate solution and boiled until hydrolysis is complete. The precipitate is calcined at 700‹C. Specification 405,669 is referred to.
Patent GB-239875-A (GB)
Title: Improvements in photographic printing materials
IPC: G03C1/52
Filed: 1925-09-11
Abstract: 239,875. Schwarz, R. Sept. 12, 1924, [Convention date]. Plates, films and papers.-Photographic printing-material which, on exposure to light and development, yields an image in a predetermined colour, is produced by distributing in a vehicle an azo dye component and a nitrito complex salt which is decomposed by light, and applying the mixture to a support such as glass, paper, tissue, &c. The mixture may also contain a light-sensitive metal salt such as silver chloride, which acts as a catalyst. The action of light on the nitrito salt is to set free the NO2 radical in the form of a nitrite, and this effects the diazotization of the dye component (an aromatic amine), producing a diazo compound which is converted into an azo dyestuff by development. In an example, a gelatine emulsion containing dinitro tetramine cobalt chloride, m-phenylenediamine, and silver nitrate is spread upon paper and exposed to light. On developing with dilute hydrochloric acid, a brown image is obtained. The silver salt and the unexposed portions of the complex salt are removed by treatment with hypo and washing. Further examples are given in which by replacing the m-phenylenediamine (1) by the sodium salts of 1.5-naphthylaminesulphonic acid and 2-oxy-3.6-naphthalene disulphonic acid a carmine red image is produced, and (2) by the sodium salt of 1.8-aminonaphthol- 4.6-disulphonic acid and benzidine a blue-violet image is produced, development in both cases being performed with dilute hydrochloric acid followed by a solution of sodium carbonate. It is stated that finely-divided carbon or metals will also act as catalysts in the layer.

Title: System for controlling the position of the anchorage point of the piloting channel of an aircraft
IPC: G05D1/00
Filed: 1975-05-23
Abstract: 1497182 Aircraft control SOC NATIONALE INDUSTRIELLE AEROSPATIALE 23 May 1973 [6 June 1974] 22842/75 Heading G3N [Also in Division B7] A system controls the anchorage point position of an aircraft piloting channel e.g. for a helicopter which can be piloted manually or automatically. A control column 1 provides pitch control, via linkage 3, and roll control, via linkage 4, to a wobble plate acting on the incidence of the craft rotor blades using servo control rams 6T, 6R. Linkages 3, 4 are pivoted to crank pins MnT and MnR of mechanical relays Rt and RR, the pins being free or electromagnetically locked using a resilient force limiter in a position imparted to the crank pin by trim motor MT or MR of the corresponding relay. A locked pin serves as an anchorage point for a servo control ram (ST and SR respectively) under control of automatic pilot PA which has a pitch part PAT controlling ram ST and a roll part PAR controlling ram SR. Action on linkages 3a, 4a can arise from manual action on the control column or from servo control action. Manual piloting is effected by applying sufficient force to the control column to overcome the resistance of the resilient limiters or by releasing pins MnT and MnR. The automatic pilot is cut into operation by switches 7T and 7R for pitch and roll respectively. The trim motors are energized via an electronic switch and two logic arrangements integrating the manual and automatic data coming from the piloting channel, Fig. 2 (not shown).
