Title: Flavouring substances and their preparation
Inventor: MAY CHARLES GERARD
IPC: A23L27/21
Filed: 1956-12-27
Abstract: Substances having ham or bacon flavour, for use as solutions or powders and for incorporation in protein gels, meat spreads, dry soups, luncheon meats, rissoles and cooking fats, are made by heating an amino reagent comprising cysteine with fractionated liquid wood smoke in the presence of water.  The liquid wood smoke is obtained by dry distillation of wood, e.g. oak, beech, hickory or ash sawdust, at slow combustion temperature-300-500 DEG C.-in the presence of air. The liquid is freed from methyl alcohol by distillation and from aliphatic acids by distillation or by neutralizing with alkali.  The fraction having a b. pt. above 40 DEG C. at 15 mm. of mercury pressure is preferred.  The amino reagent preferably comprises, in addition to cysteine, at least one of the amino acids threonine, proline, glutamic acid, valine, leucine, lysine, aspartic acid, tyrosine, glycine, a - or b -alanine, arginine, iso-leucine, histidine, serine; salts of amino acids, e.g. monosodium glutamate, and esters, hydroxy compounds, peptides and proteins which will give rise to the desired amino acids under the conditions of the reaction may be used.  Suitable amino reagents are cysteine with a deflavoured fish protein or a groundnut or casein hydrolyzate treated with charcoal to remove readily adsorbed amino acids.  Specification 784,905 is referred to.

Patent GB-1007962-A (GB)
Title: Improvements relating to record material punching machines
Filed: 1964-09-30
Abstract: 1,007,962. Selective punching machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 30, 1964 [Oct. 30, 1963], No. 39743/64. Heading B4B. A machine for punching record material 11 comprises a plurality of hollow punches 14, a plurality of solid anvils 17, rollers 10 for feeding the material between the punches and anvils and means for selectively moving the anvils so that each selected anvil co-operates with a punch to punch the material. The punches, which each have a through hole 15, are carried by a continuously-rotating cylinder 13. Operation of each anvil is controlled by a selection mechanism comprising a lever 18, interposer 19, interposer lever 20, restoring lever 21, operating element 22, anvil cam 23, rotary cam 24 and holding means 25. Lever 20 is normally latched by the means 25 but is freed to pivot under the action of spring 33 when electromagnet 38 is energized. The electromagnets are selectively energized by means of brushes 46 at sensing station 47 or by means of brushes 48 at sensing station 49. When it is desired to produce a hole in the material, an upward force 53, Fig. 3, is applied to the selected anvil and this force is timed to occur after the preceding punch has passed over the anvil. As shown in Fig. 4, the force 63 lifts the anvil and material fully into position before the leading edge 54 of the selected punch has passed through the area of maximum restriction. In Fig. 5, the anvil is held in its raised position while the selected punch pusses fully over it. The shouldered portion 17a on the anvil strikes support 12 limiting the upward travel of the anvil and material so that the selected punch passes sufficiently through the material to fracture it to form a chip 55. As the trailing edge 56, Fig. 6, of the selected punch moves past the punching position, the force 53 is reversed. When the anvil is fully retracted, the chip is retained on the punch until mechanically forced into the throughhole of the punch by the pressure of later chips. The chips are removed from the cylinder 13 by a source of vacuum connected to the hollow shaft 16 of the cylinder.

Title: Improvements in or relating to electric impulse transmitters and to telephone station apparatus incorporating electric impulse transmitters
IPC: H04M1/677
Filed: 1962-10-22
Abstract: 995,102. Telephone dials. ASSOCIATED AUTOMATION Ltd., GENERAL ELECTRIC CO. Ltd., A. YOUNG, and J. H. LEWORTHY. Jan. 15, 1964 [Oct. 22, 1962], No. 39954/62. Heading H4K. In a dial preferably of the kind described in Specification 518,721, auxiliary springs 6 which are normally closed are controlled by cams 14, 15 loose on the shaft 2 of the finger plate 3 in such a way that they open when the digit 0 is dialled provided it does not follow a digit other than 0. When 0 is dialled, an arm 26 on the shaft 2 rotates sufficiently to engage a pin 25 on the cam 14 and move it off-normal, in which position it remains until the arm 26 again strikes the pin 25 at the end of the return movement. A cam follower 27 allows the springs 6 to open. The cam 15 has two off-normal positions to which it is moved by successive settings of the finger plate 3 through a cranked lever 34 and pawl 32, there being a retaining detent 30. If the first digit dialled is 0, however, the movement of the cam 14 withdraws the detent 30 and allows the cam 15 to return to normal. But if the digit 0 follows another digit, the cam 15 goes to the second off-normal position, and it is no longer released by the cam 14. In this position it prevents the control of the cam follower 17 by the cam 14. A further cam 16 has a projection 40 coupled to the cradle switch so that the cam moves through a small angle when the handset is removed or replaced, and thus releases both the pawl 32 and detent 30, allowing the cam 15 to restore. By giving the cam 14 a second pin it may be arranged to control the springs 6 when either 9 and 0 is dialled. The circuit shown in Fig. 6 is intended for a system in which the first digit 0 indicates a trunk call, while the number 000 is used for emergency calls. When O is dialled as the first digit springs 6 open as described above and relay A energizes. On the return of springs 6 the impulse springs 1 are short-circuited unless 0 is again dialled or unless contacts 41 forming part of a keyoperated lock are opened.

Abstract: Compounds of divalent tin of general formula: <FORM:0993004/C2/1> where R is substituted or unsubstituted phenol or thiophenol and R1 is a substituted or unsubstituted pyrocatechol are used as polymerization catalysts.  In Examples (1) the catalyst <FORM:0993004/C2/2> R=C4\H9-O-CH2- is prepared by decomposing paraformaldehyde in butanol in the presence of sodium hydroxide to produce the semi-acetal into which is stirred pyrocatechol, giving on neutralization and purification an isomeric mixture of butyl ethers of pyrocatechol. A benzene solution of this mixture is heated and an aqueous solution of tin-II-chloride added dropwise together with aqueous sodium hydroxide; on purification and separation the tin derivative of a polymethylol butyl ether of pyrocatechol is obtained; (2) an identical process using the thiophenol produces <FORM:0993004/C2/3> (3) 2,6-di-t.-butylphenol in semi-acetal of n-butanol and formaldehyde are condensed, water removed, neutralized, aqueous tin-II-chloride and sodium hydroxide added dropwise, water removed, CO2 passed through, and impurities removed to give <FORM:0993004/C2/4> R=tertiary butyl; (4) the semi-acetal of n-butanol and formaldehyde is replaced by ureamono-N-methylol-butyl ether to give <FORM:0993004/C2/5> R=tertiary butyl; while (5) phenol replaces the pyrocatechol of Example (1) to give a tin-II-phenol derivative mainly substituted in the ortho- and para-position with methylene-n-butyl ether.ALSO:Formaldehyde is polymerized at - 20 to + 120 DEG  C. in the presence of a tin compound of formula <FORM:0993004/C3/1> where R is a substituted or unsubstituted phenol or thiophenol radical and R1 is a substituted or unsubstituted pyrocatechol radical. The polymerization may be carried out in an alkylating agent or in an acylating agent or in the gaseous phase in the presence of high molecular weight polyoxymethylene present in the form of a fluidized bed.  Specified catalysts have the formulae <FORM:0993004/C3/2> where R is C4H9-O-CH2-; <FORM:0993004/C3/3> where R is C4H9-O-CH2-; (3) <FORM:0993004/C3/4> where R is tertiary-butyl; (4) <FORM:0993004/C3/5> where R is tertiary-butyl; and (5) the divalent tin salt of 8-hydroxyquinoline.  The polymerization may take place in solution, preferably in methylene chloride or ethyl orthoformate, and may be continuous or not.  The formaldehyde and the catalyst may be added gradually to the polymerization medium.
