Abstract: 1,138,245. Liquid level measuring. PRECISION MECHANIQUE LABINAL. 1 Aug., 1966 [30 July, 1965], No. 34497/66. Heading G4H. [Also in Division H2] In apparatus for measuring the level of a liquid, as the level changes the tension in a wire 2 (Fig. 4) supporting a float 1 varies to disturb the balance of an arm 4 so that via contacts or a magnetic shunt mechanism a motor is driven in one of two directions to (a) rotate a drum 3 on which the wire is wound until a balance is again obtained and (b) to control a counter. In the embodiment described the continuous motion of a shaft 70 (Fig. 13) driven by the motor controls the stepping motion of a shaft 70<SP>1</SP> via a magnetic mechanism (see Division H2) the shaft 70<SP>1</SP> controlling the rotation of five decade wheels 28 (Fig. 9) of the counting mechanism. Transfer members between the decades are in the form of Maltese crosses.

Title: Retrospective pulse modulation
IPC: G06V30/224
Filed: 1972-02-24
Abstract: 1359288 Retrospective pulse modulation INTERNATIONAL BUSINESS MACHINES CORP 24 Feb 1972 [5 April 1971] 34686/73 Divided out of 1350737 Heading G4C A record carrying retrospective pulse modulated information is read by deriving input pulses representing transitions in the data which are fed to a circuit including a mono-stable and a bi-stable, each responsive to the input pulses such that on reception of a pulse the bi-stable assumes a state which is dependent on the state of the mono-stable circuit at the time of reception of the same pulse. In the embodiment of Fig. 3 a magnetic strip recorded to have intervals of one or two units between transitions, as shown in Fig. 4(b) is read by a magnetic transducer 30 and associated amplifier 32 to derive the signal of Fig. 4 (b). After rectification (Fig. 4 (c)) the resulting strobe signal is fed via a small delay 42 to mono-stable 40 which holds its output at terminal 48 (Fig. 4 (e)) for one and a half units after each strobe pulse, the complementary signal being derived at terminal 44 (Fig. 4 (f)). The strobe signal and the output of circuit 40 are fed to AND gates 54, 52, receiving at their other input the strobe signal. The output signals (Figs. 4 (g), 4 (h)) from the gates 54, 52 are fed to further AND gates 64, 66 and 62, 68, respectively, where they are combined with the outputs of bi-stable circuit 50 receiving at its input the output of gates 54, 52 and holding its output for 1 unit. The output signals from gate 64 and gate 62 are combined to derive a signal (Fig. 4 (o)) representing the binary "1" in the input data, the outputs of gates 68, 66 being combined to derive a signal (Fig. 4 (t)) representing the binary "0". In the embodiment of Fig. 5 (not shown) the signal from the magnetic transducer is fed after rectification to a mono-stable (40<SP>1</SP>) holding its output for one and a half units. This signal is applied as an enabling input to a bi-stable (50<SP>1</SP>) triggered by the strobe pulses. The output signal from the bi-stable is fed to an exclusive OR gate (60<SP>1</SP>) receiving at its second input the output of the mono-stable. The resulting signal may either be fed directly to an AND gate (100) receiving at its second input the strobe signal delayed by a delay (102) to derive a pulse output train representing the binary "0" in the data or, if regeneration is necessary it may be fed via an inverter (88) and further bi-stable (90) to the AND gate. A similar pulse train for the binary "1" is derived by combining the inverse output of the second bi-stable with the strobe pulses. The output can be converted to the NRZI format by the addition of a conventional latch circuit.

[Class 83 (ii)] Return bends in tubular heat-exchangers such as vapour generators comprising a wall consisting of serially connected small bore tubes with adjacent lengths lying alongside and in contact or substantially in contact with one another are made by welding the ends of adjacent tube lengths around adjoining or opposing parts of their peripheries and then welding a cap to the ends of the tubes and to the filling of weld metal between opposing parts of the tube ends. The series of tubes may form the furnace wall of a vapour generator as described in Specifications 489,168 and 490,452, [both in Group XIII]. Welding is effected by depositing metal at 223, 224 to fill out the V-shape spaces on either side of the tangent point and also across this point at 225, and an elliptical cap 226 is flush welded at 227 on the outside, the cap being of the same thickness as the tubes at the weld and of greater thickness elsewhere.

Patent GB-912559-A (GB)
Title: Metallic salts
IPC: C07C57/48
Filed: 1960-10-12
Abstract: The invention comprises metallo metallic salts of unsaturated carboxylic acids in which the carboxyl carbon atom is linked to the metallo substituted carbon atom through an unsaturated bivalent hydrocarbon linking group involving only carbon to carbon double bonding, the metallo substituent being an alkali or alkaline earth metal (including magnesium and beryllium).  The unsaturated bivalent hydrocarbon linking group contains 2 to 14 carbon atoms and contains a single double bond, i.e. a bivalent vinylene group -CR=CR- where R is hydrogen or C1 to C6 alkyl, a conjugated double bond system or a carboxylic aromatic system.  The compounds of the invention may be represented by the formula <FORM:0912559/IV (b)/1> wherein M is an alkali or alkaline earth metal, M1 is a metal.  L is an unsaturated bivalent hydrocarbon linking group as defined, x and y are integers each equal to the valency of M1 and z is an integer equal to the valency of M, R represents hydrogen or a hydrocarbon group or other group unreactive with hydrides or amides of alkali or alkaline earth metals or these metals themselves.  Typical compounds are a -sodio sodium p-toluate, a -sodio sodium-o-toluate and g -sodio sodium crotonate.  They may be prepared by reacting a metallic salt of an unsaturated carboxylic acid in which the carboxyl carbon atom is linked to a carbon atom carrying at least one hydrogen atom through an unsaturated bivalent hydrocarbon linking group as defined with an alkali or alkaline earth metal amide, hydride or the free metal.  The reaction may be conducted at a temperature up to 250 DEG C. but no higher than the decomposition temperature of the product.  It is preferred to use stoichiometric proportions, but if desired an excess of the metal carboxylate may be employed.  The reaction may be carried out in a ball mill in an inert atmosphere such as argon, krypton or nitrogen, free from moisture.  An inert liquid blanket e.g. a high boiling mineral oil may be used if desired.  The product may be reacted with an organo mono-halide and acidified to give an acid. It may also be carbonated, acidified and hydrolysed to give a dibasic acid.  Example 1 describes the preparation of a -sodio sodium crotonate from sodium crotonate and sodium amide and its reaction with benzyl chloride to produce upon acidification, a mixture of 5-phenyl-2-pentenoic acid and 2-benzyl-2-butenoic acid. In Example VIII a -sodio sodium-o-toluate is prepared and converted by carbonation and acidification to homophthalic acid. a -sodio sodium-p-toluate in a similar manner gives homoterephthalic acid.
