Moulding indiarubber. - Tubes are made by applying a rubber dispersion to the interior of a horizontal cylindrical mould and rotating the mould on its axis while subjecting the dispersion is the action of means for setting and for coagulating the rubber. The dispersion may be concentrated for example as described in Specification 290,313, [Class 70, Indiarubber &c.], and fillers, vulcanizing agents &c. may be added. Small quantities of coagulants may be added and the mould heated during rotation or dehydrating and setting solutions as described in Specification 303,544, [Class 70, Indiarubber &c.], may be employed. Drying may be assisted by passing a current of air through the mould. For thick tubes, the process may be carried out in stages.

Title: Method for the recovery of off gases
Inventor: WILLETT HOWARD PARKER
IPC: F27D17/00
Filed: 1969-04-22
Abstract: 1,235,803. Recovering combustible gas. CHEMICAL CONSTRUCTION CORP. 22 April, 1969 [3 May, 1968], No. 20610/69. Heading C5E. [Also in Division F4] In a method of recovering off-gas from an oxygen-blown steel converter 36 having an airventilated hood 41, the hot off-gas is quenched with a liquid 44, preferably water, which is at least partially vaporized, the vapour being subsequently removed at 46, the flow rate of the final cold gas stream being kept constant during the blow period at a level which maintains the rate of air induction into the hood 41 during the peak of the blowing period at a value below that necessary to combust all of the generated CO to CO 2 , and above that necessary for such combusting during the onset and end periods. The cold gas flow rate is automatically controlled by a louvred damper 50 responsive to the current or power passed to an electric motor 55 which drives a blower 51, and the CO-containing gas stream 53 may be collected during the peak blowing period. The liquid 44 may be a hydrocarbon which is cracked at least partially during quenching to provide an enriched fuel gas. In another embodiment, see Fig. 1 (not shown), the gas flow is controlled automatically in response to pressure and temperature measurements (27, 29, 30) in the gas stream. The method produces an " inert plug " of N 2  and CO 2  separating the peak (CO, N 2 , CO 2 ) from the onset and end periods (O 2 , N 2 , CO 2 ). The rate of air induction into the hood during the peak of the blow period is less than 50% of the quantity required for complete combustion of CO, and in a modification, the flow rate of pure O 2  to the converter is increased rapidly in a stepwise manner before the peak period and decreased rapidly in a stepwise manner after the peak period.

Title: Polyurethane synthetic resins
Inventor: ROSENDAHL FRIEDRICH KARL
IPC: C08G18/83
Filed: 1964-05-19
Abstract: Polyurethanes containing groups obtained by reacting isocyanate groups with water, primary or secondary amines, hydroxylamines, hydrazines, polyhydrazides, polysemicarbazides, polycarbazinic acid esters or carbohydrazides are stabilized against discoloration and oxidation by adding 0.1-15% by weight of a 1 : 1-dialkyl substituted semicarbazide or carbazinic acid ester either before, during or after the formation of the polyurethane resin.  The polyurethane may be formed from a polyester polyesteramide, polyether, polythioether or polyacetal by reaction with an organic polyisocyanate. The stabilizer may be added to a solution of an -NCO terminated preadduct in a polar solvent either before or after the addition of a chain lengthening agent, or to the liquid preadduct or its melt.  Other stabilizers e.g. phenols and alcohols may be included.  In Example (5) a polytetrahydrofuran polyether thioether was prepared by the polymerization of tetrahydrofuran with chlorosulphonic acid, followed by saponification of the -OSO3H group with steam to the OH group and reaction of the -CH2Cl group with mercaptoethanol. The polyether was reacted with excess diphenylmethane 4,41-diisocyanate in chlorobenzene to form an -NCO terminated prepolymer which was then reacted with carbodihydrazide in dimethyl formamide and hexane 1 : 6-diisocyanate in chlorobenzene and pigmented with TiO2. To the solution was added the reaction product of <FORM:1049714/C3/1> and 3 mols of 1 : 1-dimethylhydrazine as stabilizer.

Title: Improvements in or relating to telegraphy

Filed: 1926-08-23
Abstract: 282,476. Smith, W. S., McLachlan, N. W., and Jacob, W. G. R. Aug. 23, 1926. Systems employing non - contact - making relays; restoring or modifying imperfect signals. -Received signals are applied to the field winding of a dynamo-electric generator 5, 11, the cutput of which is applied to the grid of a. thermionic valve, so that the load on the generator is very small. Several generators and valves may be arranged in cascade and where the last element is a generator the low impedance of the armature makes the arrangement suitable for use with a recorder. In the arrangement shown in Fig. 1, signals received from a cable are applied to the grid of the valve 4, the plate current of which passes through the field winding 5 of a generator 11 which is driven at constant speed, the output of the generator being applied to the grid of a second valve 14. The output of the latter is delivered to a telegraphic recorder directly or through a cascade of devices of the kind shown in Fig. 1. The field due to the constant D.C. component of the plate current is neutralized by an additional winding 7 fed by the plate battery 6 through regulating resistance 8 and inductance 9, so that the output voltage of the generator 11 is zero unless signals are being received. The same result may be obtained by means of a push-pull arrangement of two valves 32, Fig. 2, or by shunting the winding 5 by a resistance 46, Fig. 6, two high tension batteries being employed; or by separating the winding 5 from the valve by a blocking condenser (Fig. 5, not shown). The generator 11 may be D.C. or A.C., and in the latter case the final output may be rectified and smoothed. The field windings 5 may be divided into sections each of which is associated with a valve or valves. The brushes 10 may (Fig. 7, not shown) be connected to the grids of a push-pull pair of valves, the filaments of which are connected to a middle brush; and the armature may (Fig. 8, not shown) be wound over with an electrostatic screen comprising an earthed and insulated spiral wire or a wrapping of metal foil. Restoring or modifying imperfect signals.-A signal shaping network 42, 43, 44, Fig. 3, may be interposed between the valve 4 and winding 5. In a modification (Fig. 4, not shown) the condenser 44 may be omitted, the inductance 42 and resistance 43 being in that case shunted directly across the winding 5. The output from the generator 11 may be shaped by a, series choke 15 and shunt condenser 16, Fig. 1.
