Title: Improvements in and relating to temperature control devices for electric blankets
IPC: H05B3/34
Filed: 1948-02-19
Abstract: 653,641. Automatic temperature control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 19, 1948, No. 4928. Convention date, Feb. 20, 1947. [Class 38 (iv)] The temperature of an electrically heated blanket is maintained constant by means of a valve operated relay controlling the heating circuit. As shown, a blanket 1 includes heater elements 6, 7 energized from a source 11, 12 by operation of a relay 23. The blanket also includes a temperature sensitive resistance 8 which, in series with an adjustable regulating 13, forms one arm of a bridge network energized from source 11, 12. The filament 19 of an emission limited diode 18, the diode being such that the plate current is dependent entirely on the filament current, is connected across the output of the bridge. Variations of the resistance of 8, due to variations of the temperature of the blanket, cause variation of the filament current, and therefore of the plate current of the diode to operate the relay 23 which controls the heating of the blanket in a sense to correct for the variations. Close regulation is achieved by a resistance 30 connected in series with the heater windings 6, 7 in such a manner that this combination is in parallel with the resistance 8 when the relay 23 is de-energized, but when the relay is energized the resistance. 30 is connected in parallel with a resistance 15 which forms another arm of the bridge network. The effect on the filament 19 of variations in line voltage is compensated for by a resistance 17 having a high negative temperature co-efficient.

Filed: 1961-02-28
Abstract: 990,407. Drafting fibres. JAMES MACKIE & SONS Ltd. Feb. 12, 1962 [Feb. 28, 1961], No. 5310/62. Divided out of 987,982. H, ading D1D. In drafting apparatus for the treatment of a number of parallel slivers in which the draft is regulated in accordance with the average thickness of the slivers entering the drafting zone and in which the thickness of each sliver is measured by the displacement of a measuring roller 15 about its carrier pivot 19, the roller 15 comprises two portions 15a and 15b mounted for individual rotation on a stud 16 centrally pivoted on pins 17 in the roller carrier 18 so that each roller portion 15a or 15b is individually displaced by different halves of the associated sliver and the displacement of the centre of the roller (and therefore the rotation of the roller carrier 18 and an extension 20 about the pivot 19) is a measure of the average thickness across the sliver width. This average thickness across the width of each sliver is therefore represented by the position of the respective lever 20. The positions of all these levers are then averaged by the lever mechanism 22, 23, 24, 25, 26 and 30 shown more clearly in Fig. 3 (nor shown) so that the average thickness of all the slivers entering the drafting zone is represented by the position of the end of the single rod 30. which as shown in Fig. 1, sets a known time delay mechanism 32 for the appropriate adjustment of the draft. In a further arrangement a complete sliver may be associated with each portion 15a or 15b of each roller 15 so that the position of each extension 20 is a measure of the average thickness of two slivers and not the average thickness of a single sliver across its width. Specification 880,871 also is referred to.

The electrodes which are applied to the objects to be soldered so as to embrace them may be made of an alloy sold under the Registered Trade Mark " Monel." The body, which is made of electrically. and heat insulating material, is in halves provided with a pistol grip and contains a bent metal bar 20 to which is secured the electrode 13 and a conductor 5. The electrode 12 is carried in a holder 21 pivoted at 17 in the body and secured at its other end to a link 11 of a toggle 11, 19, the link 19 being pivoted at 7 and being integral with an internal trigger member 9. An external trigger 8 which is also pivoted at 7 carries the movable element 3 of a switch 3, and connected to the other conductor of the circuit and is grooved to receive the spring 10 for operating the trigger 9. When the trigger 8 is pressed the toggle 11, 19 is straightened by movement of the trigger 9 by the spring 10 and the switch member 3 then engages the member 2 to complete the circuit of the secondary of a transformer. On releasing the trigger 8 the switch is first opened and the electrodes are then separated by the spring 15. The rod 21 is also connected to the pivot 7 by a conductor 22 to prevent sparking at the link connections. The closing and opening of the electrode is controlled by adjustable stops 14, 16.

Title: Improvements in steam turbine blades, and in the method of manufacturing such blades
IPC: F01D5/28
Filed: 1923-02-23
Abstract: 195.050. Akt.-Ges. Brown, Boveri, et Cie. March 18, 1922, [Convention date]. Case-hardening. - Blades for steam turbines are hardened only in those parts which are most exposed to erosion, more particularly the upper part of the leading edge of the blade as indicated by hatchings, Fig. 2. The whole of the edges may be hardened as indicated in Figs. 3 and 4, the head of the blade being left soft to facilitate riveting the binding ring a. One method of making the blades consists in employing a material which of itself cannot be hardened. and coating this material at the places where it is not to be hardened with, for example, an electrolytic deposit which does not allow any carbon to penetrate, and then, by a casehardening operation, enriching the unprotected places with carbon, and then hardening such places by subsequent quenching. To prevent distortion, the blade, before quenching, may be clamped in a rigid mould, or be bent in the opposite direction to compensate for the distortion due to the hardening. Those parts of the hardened blade which are to remain soft may be softened again by tempering after the hardening.

Abstract: 1303836 Fuel elements COMITATO NAZIONALE PER L'ENERGIA NUCLEARE 5 Feb 1970 [6 Feb 1969] 5623/70 Heading G6C A spacer grid for use in a fuel element comprising an assembly of parallel, spaced fuel rods consists of laminar members disposed end-on to the coolant flow, the contact of the members with each fuel rod being along three generatrices thereof which are spaced at equal angles from one another, each rod being rigidly supported at two of the contact lines and elastically at the third. In the embodiment shown in Figs. 1 and 2, the grid is formed from two types of laminar members having the same height h and crossing each other at right angles. The members 2 of the first type, of which there are twice as many as of the second type, are made of a thin metal band along which at regular intervals equal to twice the side a of the square grid mesh, two parallel lengthwise incisions are made at a distance from the edges of the band equal to  the band width. The band is then pressed in such a way that the portion between the two incisions forms a bridge projecting from one side of the band, while the other portions form similar narrower bridges projecting from the other side of the band. The members 3 of the second type are also made of a thin metal band which at regular intervals equal to the side a of the square grid mesh is incised and pressed similarly to member 2, the bridges however being shallower and having an outwardly arcuated profile for greater elasticity. The members 2, 3 are interlocked at right angles by means of vertical slits extending for ¢ their height, a short tubular element 14 provided with four slots 90 degrees apart being inserted at each crossing of the members 2, 3. Each fuel rod 1 abuts against the mesh structure along three generatrices of the rod for a length equal to ¢ L. The corners 4, 5 of the bridges of the members 2 provide rigid support while the ridges 6 of the profiled bridges of the members 3 provide elastically yielding support. In other embodiments, the bridges are formed by rectangular inserts with rounded off corners such as may be obtained by sawing a thinwalled tube of rectangular cross-section into sections (Fig. 4, not shown) and the structural members corresponding to the members 3 of the first embodiment comprise flat bands inserted between two bands corrugated in such a way that curved vertical ridges are obtained facing the fuel rods (Fig. 6, not shown).
