Title: Improvements in or relating to Level Gauges for Tanks and the like.
Inventor: JACQUES HENRI REVOIL
IPC: G01F23/00
Filed: 1919-11-27
Abstract: 135,869. Revoil, J. H. Nov. 27, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Indicators actuated by floats.-A liquid-level gauge for tanks and the like is operated by the variations in the upward thrust of the liquid discharged by a hollow piston extending to the bottom of the tank. The piston 0 depends from a nest of elastic disks C enclosed in a chamber B filled with liquid and attached to the top of the tank A. The chamber B is in .communication through a conduit b with an elastic chamber F filled with liquid. A pointer I, working across a scale K graduated in accordance with the depth or volume of the liquid in the tank, is carried by a disk H which gears with a rack G secured to the chamber F. To compensate for the effect of pressure of the liquid, the ,chambers B, F and the conduit b on the pointer I, duplicate chambers L, J, and conduit l are provided with the terminal element J acting on the opposite side of the rack G. When the gauge is applied to a boiler, the gauge is submitted to the boiler pressure by providing the fluid-tight chambers M, 0 communicating by way of a tube q.

Title: Pneumatic stowing machine, particularly for mining

Filed: 1959-09-02
Abstract: 882,259. Pneumatic conveyers. OELBRICH, A., [trading as MACHINENFABRIK UND EISENGIESSEREI A. BEIEN], KUHME, E., and BRIEDEN, K. W., [trading as MASCHINENFABRIK K. BRIEDEN & CO. KOMM. GES.]. Sept. 2, 1959 [Sept. 12, 1958], No. 29901/59. Class 78 (1). In the pneumatic stowing machine for use in mining described in Specification 808,459, the operating piston 15 in the cylinder 16 of the clamping device can be loaded, on at least one side up to a pressure value which completely, or almost completely, cancels out the compressibility of the pressure medium while between the loads directed in opposition to one another there is only a pressure difference sufficient for the contact pressure of the wear discs 7, 8. A pump 25 is connected to the cylinder through a reversing valve 26 and lines 23, 24. At first the piston is subjected to a pressure of 40 atmospheres by way of the line 24 and the wear discs are pressed against the end faces of the cell wheel. Further operation of the pump brings the pressure below the piston up to 150 atmospheres. The valve 26 is then changed over. The space above the piston is then filled with pressure fluid at 110 atmospheres and the effective pressure in the clamping device is reduced to 40 atmospheres. The pressure fluid in both chambers of the cylinder is compressed so that it is practically in elastic and permits no undesired movements of the wear discs away from the wheel. In modifications (Figs. 2 and 3, not shown), the hydraulic pressure is replaced by the action of spring discs and a coil spring respectively.

Abstract: 976, 232. Counters. STANDARD TELEPHONES & CABLES Lfd. Aug.18, 1961 [Aug. 20, 1960], No. 29911/61. Heading G4A. A ring-type counter made up of cross-connected transistor pairs is arranged with one of the pairs unsymmetrical so that application of operating voltages at switching on automatically presets the counter. When the circuit is switched on the absence of a resistor in parallel with capacitor C43 ensures that transistor T41 is blocked because zero potential is applied to its base electrode. The right hand transistors T 11 , T 21 , T 31  are then rendered conducting over the connection from the collector of T41 and resistors R19, R29, R39 to their base electrodes. Similar connections ensure that the ring steps on to input pulses applied to C1

Title: Catalysts for the polymerisation of anhydrocarboxy-ª‡-amino acids
IPC: C08G69/10
Filed: 1948-11-19
Abstract: Anhydrocarboxy-a -amino acids are polymerized or copolymerized in the presence of the sodium or potassium salt of an a -amino carboxylic acid.  Suitable anhydrocarboxy derivatives are those of glycine, sarcosine, N-phenylglycine, pyrrole-a -carboxylic acid, proline, a  - aminocyclohexane carboxylic acid, alanine, valine, phenylalanine, leucine, cysterine, methionine, tyrosine, glutamic acid, lysine, histidine and a -aminoisobutyric acid. Polymerization is preferably effected in solution, e.g. in benzene, chloroform, ethyl acetate or dioxan.  Temperature may be raised up to 50 DEG  C.  The salts may be formed in situ, e.g. by adding an alkali with sufficient water for the formation of the salt.  If desired a solvent containing a little water for salt formation may be employed.  Preferably the reaction is performed in absence of water, the products being obtained after removal of solvent as optically clear, flexible films.  They may be used for fibres or as textile finishing agents.  With low proportions of catalyst, the products may be clear, flexible films with a molecular weight of about 15,000.  With more catalyst the molecular weight tends to be lower and the product brittle. Copolymers obtained preferably by the use of 0.5-1.5 per cent of sodium or potassium phenylalaninate from N-anhydrocarboxy-l-leucine and N-anhydrocarboxy-dl-phenylalanine or from the derivatives of dl-phenylalanine and a -aminoisobutyric acid form films especially resistant to acid or alkali.  In the examples moisture is excluded from the reaction zone by guard tubes containing magnesium perchlorate and calcium sulphate.  (1) Anhydrocarboxyphenylalanine and anhydrocarboxy-a -aminoisobutyric acid are copolymerized in presence of sodium phenylalaninate and dry benzene; (2) as in (1) using benzene containing 0.05 per cent water; (3) as in (1) using sodium lysinate in place of sodium phenylalaninate; (4) as in example (2) with sodium carbonate in place of sodium phenylalaninate; (5) anhydrocarboxy:l-leucine and anhydrocarboxy-dl-phenylalanine were added to benzene containing 0.05 per cent water and sodium carbonate; (6) sodium-a -aminoisobutyrate is added to anhydrocarboxyphenylalanine and anhydrocarboxy-a -aminoisobutyrate in benzene; (7) as in (6) using potassium l-leucinate in place of sodium a -aminoisobutyrate; (8) sodium phenylalaninate is added to anhydrocarboxy-l-leucine and anhydrocarboxyphenylalanine in dry benzene.
