Title: Improvements in or relating to the chlorinatlon of methane
IPC: C07C19/10
Filed: 1921-11-22
Abstract: In the chlorination of methane steam is employed as a diluent to the reacting gases to moderate the violence of the reaction and at the same time to supply if necessary the heat for its initiation.  In general 2-5 volumes of steam per unit volume of chlorine are used and temperatures above 650 DEG  C. avoided owing to the decomposition of steam and formation of oxides of carbon. Catalysts such as chlorides of copper, iron, and the alkaline earth metals may be employed, with or without porous carriers. The relative proportions of the reacting gases are dependent on the dimensions of the reaction tubes and upon the products required.  Examples are given in which the formation respectively of methyl chloride, methylene dichloride, chloroform, and of carbon tetrachloride is promoted.

Title: Vibration damper phase-tuning process
IPC: F16F15/12
Filed: 1960-09-12
Abstract: 966,856. Testing vibration dampers. G. S. PIDD. Aug. 2, 1961 [Sept. 12, 1960], No. 31303/60. Heading F2S. In a method of testing, improving, and controlling the manufacture of tuned vibration dampers consisting of elastic and friction elements which give rise to a combined force, or couple, on inertia elements, the vector amplitudes are measured at both ends of the elastic and friction elements, and the relative phase of these amplitudes are used to determine the values of the above elements separately so that any correction for improvement can be made. A damper to be tested is fixed to a vibratoryrotatable flywheel and pick-up means, e.g. electromagnetic, is used to measure, at different frequencies, the motion and phase of the flywheel and the damper rotary mass which are displayed, in the form of an ellipse, on the X and Y plates of an oscillograph. Typical amplitudes respectively of the damper and flywheel are indicated by vectors # L  and # F , Fig. 4, having a relative phase angle #, the diagram enabling the damping effect of the damper to be evaluated and its design to be verified.

Title: Dehydrating aqueous propynol by azeotropic distillation
IPC: C07C29/82
Filed: 1950-12-27
Abstract: <PICT:0705670/III/1> In the dehydration of aqueous solutions of propynol by azeotropic distillation using benzene as entrainer, thermal decomposition of the propynol during distillation is prevented by adding a small proportion ( 1/4 to 1/2 per cent. by weight of the propynol) of succinic acid or hydrochloric acid to the distillant.  The crude aqueous propynol obtained by reacting acetylene with formaldehyde in the presence of a catalyst and by distilling the product, may be treated with acidified methanol and the mixture then distilled in order to obtain a purified propynol-water azeotrope suitable for dehydration.  Precautions are taken to ensure that vapours containing propynol do not come in contact with surfaces heated considerably above the boiling point. The propynol-water binary, containing a small proportion of H Cl, is introduced in fractionating column 1, which is charged with sufficient benzene to ensure that the upper part of the column is filled with the benzene-water-propynol ternary azeotrope.  The ternary is distilled off at 69 DEG C., condensed in condenser 11, and the condensate is passed to a decanter where it separates into two layers.  The benzene-propynol layer is returned to column 1, and the water-propynol layer is introduced into column 3.  The propynol - water azeotrope is distilled from column 3 at 97 DEG C., and condensed in condenser 31.  A portion of the condensate is returned as reflux to column 3 and the remainder is passed to column 1.  The water obtained at the base of column 3 is rejected.  The bottoms from column 1, which comprise benzene and propynol, are distilled in column 2.  A benzene-propynol mixture at 78 DEG C. is removed from the head of column 2, and condensed in condenser 21.  A portion of the condensate is returned as reflux to column 2, and the remainder is passed to column 1.  Pure propynol is withdrawn from the base of column 2.  Specifications 508,062 and 620,298 are referred to.

[Also in Division A4] The overlapped ends U, L of a thermoplastic strap encircling a package are friction-fused together in a joint J by melting thin abutted surface layers by sliding frictional movement under pressure and maintaining the ends under pressure until resolidification of an inter face layer takes place. The strap is preferably of nylon 6-6 or of isotactic polypropylene which may be blended with copolymers of propylene and ethylene, the ends of the strap being compressed between a pair of jaws, one of which may be knurled. The strap is moved in a onedirection travel stroke either drawn between stationary jaws or moved by one movable jaw, or moved in a reciprocated travel stroke by a movable jaw. The knurled jaw imprints the fused interface layer thus providing different thickness therein with greater mechanical interlock and in a modification curved joint edge profiles between the fused layer and the strap determined by the contact faces of the jaws provide greater strength in the joint. A tab 28 left on the end L facilitates stripping of the joint. The ratio of birefringence of the fused layer and the unfused strap material determined by a polarizing microscope, is between 0.08 and 0.15, in the case of nylon 6-6, and between 0.2 and 0.45 for polypropylene.

[Classes 92 (ii) and 119.] Relates to automatic guns of the kind operating on the Blish principle, according to which the breech-block is locked by friction which is overcome when the gas pressure falls, as described in Specification 14368/14, [Class 92 (ii), Ordnance &c.], and further to such guns comprising interconnected relatively movable parts, namely the breech-bolt 11, the locking bolt 18, and the actuator 16, as described for example in Specification 161,128, [Class 92 (ii), Ordnance &c.]. The present invention consists in a method of slowing down the rate of fire by adding weight to the actuator 16. In the gun shown, the actuator is elongated to the rear of the broken line x-x shown in Fig. 3 to provide a longitudinal bore to receive one end of the recoil spring 19 the other end of which abuts against a shoulder 23 on a rod 21 that compresses a buffer 27. In an example given for a -45 calibre gun, the breech-bolt weighs 1 lb., the recoil spring has a force of 6 lbs. when the breech is closed, and the actuator weighs from 5 to 10 ounces. When the weight of the actuator was increased from 2¥ to 6¥ ounces, the rate of firing per minute was diminished from 800 to 600.

Nov. 20, 1931, No. 32241. [Class 38 (ii).] In thermionic rectifiers and like devices application of anode potential is made after the cathode has reached a predetermined temperature by an arrangement comprising a slow acting thermostatic relay T, T1, T2 having a contact T2 which is closed when the relay is cold, completes the circuit of a quick acting electromagnetic relay R which has a holdng contact R2 in parallel with T2, a contact R3 which completes the heating circuit of the relay T and a contact R1 in the anode potential supply lead which contact is in series with a contact T1 closed when the relay T is hot. The cathode heating and thermostat heating current and the energizing current for the relays R are supplied in series from A.C. mains M, the former being through transformers 6, 7, 9. The H.T. supply to the anodes of the rectifier 3 is obtained from the secondary of a transformer 4. The relay T is heated by the passage of current through it. In operation, when a switch 5 is closed, the cathode heating begins, and the relay R is energized through the contact T2. Contacts R1, R2, R3 close, R1 being in the lead to the H.T. transformer, R2 being a holding contact and R3 switching in the supply to the relay T. After a predetermined time interval contact T2 opens and T1 closes, thus switching on the H.T. supply. Should the switch 5 now be opened, relay R de-energizes and on reclosing the switch 5 is not energized again until the relay T has cooled sufficiently to open contact T1 and close contact T2.
