Title: Removal of phosgene from gaseous hydrogen chloride
IPC: C01B7/00
Filed: 1963-07-12
Abstract: Chloroformates and carbonates are prepared by reacting a gaseous mixture of COCl2 and HCl with an aliphatic hydrocarbon primary or secondary alcohol at 0 DEG  to 100 DEG  C.ALSO:Pure hydrogen chloride is obtained by a process in which the proportion of COCl2 in a gaseous mixture of HCl and COCl2, particularly one in which there is less than 1% COCl2 by weight, is reduced to 1 p.p.m. by contacting the mixture with an aliphatic hydrocarbon primary or secondary alcohol at a temperature between 0 DEG  and 100 DEG  C.  It is preferred to work at 3-10 atmos. pressure with a countercurrent flow of alcohol and HCl, in which 1.05-1.10 moles of alcohol are supplied per mole of COCl2 to be removed.  The alcohol preferably contains 2-12 C atoms and is liquid in the given temperature range. Particular examples given are ethanol, mixtures of isodecyl or 180 iso-octyl alcohols as produced by the OXO process (which are preferred) and n-butanol, n-octanol, n-decanol, n-dodecanol, isopropanol, butanol-2, octanol-2, decanol-2, ethylene glycol, diethylene glycol, diacetone alcohol or glycerine.  In an example, isodecyl alcohol, synthesized by the OXO process is introduced into a reactor and HCl containing 1000 p.p.m. COCl2 is passed through at 2 parts per minute, the mixture being maintained at 25-30 DEG  C. for 1 hour.  Less than 1 p.p.m. COCl2 is present in the product.

Title: Magnetic recording and reproducing method and system
IPC: G11B20/10
Filed: 1972-06-15
Abstract: 1391686 #-PCM systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 15 June 1972 [18 June 1971 (2) 8 Dec 1971] 28110/72 Heading G4H [Also in Division H4] Method and apparatus for magnetic recording and reproduction comprises converting the signal to be recorded into a #-PCM code of a plurality of parallel bits and applying this code, preferably through a converter, to a plurality of heads arranged transverse to the direction of tape travel in the form of signals causing magnetic saturation of the medium in one or the opposite direction, and decoding these signals to achieve playback of the original recorded signal. The #-PCM modulator is shown in Fig. 2 and comprises an A/D converter 7 under the control of a clock in generator 16 to provide to register 8 a sequence of parallel 8 bit signals which are then applied to a subtractor 9 for forming the digital signal of the value of the nth sample minus the (n-1)th sample which is applied to a 8 to 4 bit code converter 11 and to a register 12 for applying to the heads in the manner specified above. The output of converter 11 is reconverted at B and applied to adder 14 to be added to the value stored in a register 10 which forms the other input to subtracter 9. Thus if a value t n-1  is stored at 10 and the value t n  is supplied to the other input of the circuit 9, the value t n -t n-1  is supplied at 14 and added to the value t n-1  to update this value to t n  in the register 10 prior to the arrival of value t n+1 . The playback circuitry, not shown, comprises means for deriving a clocking signal in synchronism with the recorded bits and applying the bits via a 4 to 8 bit converter to an adder and register, the output of the register supplying the second input of the adder, whereby the original PCM signals are obtained which are fed to a D/A converter. A search code may be recorded by one of the heads adjacent the recorded signal information by means of a keyboard input 45, Fig. 9, and code generator whereby a start signal and a digital signal is recorded by the head via the gate 38 operated by a selector 47. When searching is in progress the keyboard is used to insert the desired code into a first shift register 48 and the tape is played back via a shaper 43 whereby when a pulse generator recognizes a start signal it opens gate 49 to allow the code present on the tape to be read into a second register 50. The values are compared and when equality is present, the recording is caused to be played.

[Class 87 (ii)] A press for forming bricks, slabs, tiles, &c. has vertically-guided connected pressure members k<1>, k<2>, the upper member carrying a plunger or plungers m for co-operating with the top of a fixed mould e, while the lower member k<2> carries a toggle link n connected to a link o pivoted to a plunger p adapted to move upwardly in the mould. In use, the pressure members which are counterbalanced, are raised by a cam-worked lever while a cam-worked slide g moves a charge of material from a hopper into the mould and, at the same time, ejects the formed article. The pressure members are then lowered to a position determined by a stop u. The toggle levers are then closed by a cam s, thus applying pressure to each end of the mould. In some cases, the pressure members are raised to polish the article before the toggle is opened. The toggles may be operated by a cam-worked connecting-rod.

The noble metals, Pt, Au, Pd and Rh are separated, particularly from the base metals e.g. Zn, Cu, NiPb and Fe, by forming a solution of the material containing the various metals and contacting this solution with an ion exchange resin which comprises a chloromethylated styrene-divinyl benzene resin in which thiourea has been incorporated e.g. by refluxing the resin with a solution of thiourea. The metal containing solution may be passed through the resin which preferentially chelates with and absorbs the noble metals and permits the base metals to pass through. The absorbed metals may be obtained by a standard elution technique using an acid or a complexing agent to form a solution of the metal or the resin may be roasted to obtain the noble metals in pure metallic form. The specification exemplifies the separation and production of pure metallic platinum.
