Title: Device for sensing information from a storage element
IPC: H03K3/315
Filed: 1962-01-29
Abstract: 987,451. Tunnel diode pulse shaping circuits; circuits employing bi-stable magnetic elements. SPERRY RAND CORPORATION. Jan. 29, 1962 [March 13, 1961], No. 3325/62. Headings H3B and H3T. The signal read-out from a storage element is applied to a semi-conductor bi-stable negative resistance device together with part of the interrogating pulse so that if information is stored in the storage element the sum of the consequent output signal and the interrogating pulse is sufficient to switch the state of the negative resistance. The interrogating pulse of a magnetic storage matrix is applied via terminal 13 to the interrogating line 12 and from resistance 14 and delay network D to a tunnel diode 18. This pulse brings the operating point of the tunnel diode close to the peak point so that if information is stored in core 11 the resulting output pulse at 16 will switch the diode to its high current condition. The delay in D is chosen so that this switching occurs at the optimum signal to noise ratio point. The output pulse ends when the delayed pulse ceases and, as the interrogating pulse is longer than the information pulse from the core, the output pulse is longer than, as well as delayed with respect to, the information pulse. An amplifier may be inserted between the core output winding and the tunnel diode (Fig. 2, not shown).

Title: Improvements in the purification of naphthalene
IPC: B01D11/02
Filed: 1953-02-11
Abstract: Crude naphthalene crystals obtained by pouring molten crude naphthalene into an aqueous medium or by crystallization from a coal tar fraction are upgraded by washing in a centrifuge with a wash solution containing less than 1 per cent of the sodium salt of di-(2-ethylhexyl) sulphosuccinate, the temperature of the solution being above 65 DEG  C. but insufficient to melt said naphthalene crystals.  Preferably the amount of surface active agent is 1/8 per cent of the total wash solution and approximately five parts by weight of wash solution are used per part of crude naphthalene.  In addition 1/2 per cent of sodium carbonate may be added to the wash solution.  The first portion of the wash solution may be collected separately and the remainder recycled at 50 DEG  C. to a subsequent batch of crude naphthalene.  Flow diagrams illustrate the purification of naphthalene obtained by (1) granulation and (2) crystallization wherein the crude material is given a preliminary wash with recycled wash solution at 50 DEG  C. followed by fresh wash solution at 70-75 DEG  C.  Granulated naphthalene may be obtained by pouring molten naphthalene into water or alkaline solution, e.g. dilute sodium carbonate, and cooling in the presence of a detergent such as soap with continuous agitation.  The temperature of the slurry should be 1 DEG  to 6 DEG  C. below the setting point of the naphthalene. The crystallizer stock may be obtained by feeding naphthalene oil continuously to a large crystallizer which is baffled so as to give a residence time of 5-24 hours and wherein the temperature is maintained within 10 DEG  C. of the crystallization point. Examples 1 and 2 give further details of the recycle process described above.  Examples 3, 4 and 5 illustrate a batch process and comparative experiments illustrate the effect of temperatures below 65 DEG  C. and washing with water alone Specifications 206,484, [Class 2 (iii)], and 694,327 are referred to.

Title: Improvements in or relating to the manufacture of derivatives of unsaturated fatty alcohols
IPC: C07B45/02
Filed: 1932-02-11
Abstract: Products resembling Turkey red oils are prepared from unsubstituted, unsaturated aliphatic and cycloaliphatic alcohols containing not less than eight carbon atoms by treating them first with an acylating agent and then with a sulphonating agent.  The sulphonation first produces saturation of the double bond or bonds, but with further treatment the hydroxy group is replaced by a sulphuric ester group with removal of the acyl group.  If the second stage is effected with chlorsulphonic acid, the acylating agent may be recovered, e.g., as acetyl chloride.  By hydrolysis of the disulphonated products, dihydroxy derivatives are obtained.  In examples: (1) commercial oleic alcohol is acetylated with acetylchloride and sulphonated with sulphuric acid and neutralized: (2) a sulphonated oleic alcohol prepared as in the previous example is further sulphonated: (3) the fatty alcohols from sperm oil are treated first with acetic anhydride and then with sulphuric acid; after prolonged treatment, the product is boiled with water and the hydrolysis completed with soda lye, whereby a hard wax is obtained which may be emulsified by means of soapy substances.  The alcohols derived from the bottle-nosed whale are mentioned.  Specification 307,709, [Class 2 (iii), Dyes &c.], is referred to.  The Specification as open to inspection under Sect. 91 comprises also the sulphonation, after acylation, of any unsaturated fatty substance containing a hydroxy group.  In an example, acetylricinoleic acid is sulphonated, a dioxystearic acid being obtained after prolonged sulphonation followed by hydrolysis. This subject-matter does not appear in the Specification as accepted.ALSO:A hard wax obtained by hydrolysis of a disulphonated unsaturated fatty alcohol derived from sperm oil is emulsified with water by means of soap or soap-like substances.
