Patent GB-973150-A (GB)
Title: Improvements in or relating to the sorting of letters and other thin flat articles
Inventor: HEWETT JAMES WILFRED
IPC: B07C3/14
Filed: 1961-08-24
Abstract: 973,150. Statistical apparatus: sorting machines. POSTMASTER GENERAL. Aug. 23,1962 [Aug. 24, 1961], No. 30612/61. Heading G4M. In a letter sorting machine the letters are printed with a series of uniformly spaced dark bars, Fig. 1, the spacing of the bars corresponding to their destinations. The letters are illuminated as they pass through the machine, light reflected from the code patterns being sensed by a first photo-cell, and the leading edge of the letters being sensed by a second photo-cell. Detection of the leading edge of the letter causes monostable circuits 102, 103, 104, Fig. 4 to be triggered. Monostable circuit 102 removes an inhibiting bias from detectors 44-46 for,a period corresponding to the length of the pattern of bars on each letter. Filters 41-43 are tuned to respective different frequencies corresponding to the destinations and supply detectors 44-46 which in turn supply an output only if a signal is present at their input for more than a predetermined period in order to reduce the effect of transient signals. An output from detector 44 or 45 energizes one or other winding of polarized relay 49 whose contact 50 prepares a circuit for operating magnet 51 or 52 of deflector 16 or 17, Fig. 2, and through OR gate 53 sets bi-stable circuit 54. When monostable circuit 103 restores to normal, circuit 54 is reset and monostable circuit 55 is triggered to operate relay 56 and energize the selected magnet 51 or 52 in time to deflect the letter to pocket 20 or 21. If, on the other hand, detector 46 produces an output, bi-stable circuit 57 is set,the latter being reset on the restoration to normal of circuit 104, and the resulting pulse from circuit 54 after being delayed by successive monostable circuits 105-109 operates relay 110 to energize magnet 112 of deflector 23 at the appropriate instant so as to direct the letter into pocket 26. Unmarked letters are directed into pocket 27. The sorter can be used for sorting envelopes of a different football pool promoters from each other and from ordinary mail, or for sorting paid cheques into groups corresponding to the originating banks.

Title: Improvements in the production of metal coils
IPC: C23F1/02
Filed: 1963-08-07
Abstract: The burrs from the cut edges of metal foil, e.g. aluminium, are removed from the foil coated with an insulating layer and in coiled form, by coiling very tightly, e.g. at above 30% of the tensile strength whereby on immersing in anodizing or etching electrolyte, the electrolyte penetrates not more than 1 mm. down the foil face. Tension is reduced as winding proceeds and preferably the average tension is 50% of tensile strength. Etching or anodizing using HCl or H2SO4 respectively, leaves a small protecting edge of the insulation, which may be a varnish or plastic layer.  The coil may be precoated with mineral or silicone oil.

Filed: 1948-12-04
Abstract: Streptomycin is obtained by growing an improved strain of Actinomyces griseus obtained by subjecting a streptomycin resistant strain of the organism to the action of a mutating agent under conditions such that the majority of the spores are killed, plating out the surviving spores on nutrient agar, transferring Actinomycete colonies thus developed to agar slants for sporulation, propagating the resultant spores, selecting a strain which shows at least a 40 per cent higher streptomycin yield, and then repeating the process with this strain until it produces at least 800 micrograms/mil of streptomycin.  In an example, a new strain called A. griseus Dulaney L-118 for which full characteristics are given, is obtained by mutating A. griseus with ultra-violet light or with nitrogen mustard (ClCH2CH2)3.  This strain is grown on a medium consisting of soy bean meal, dextrose, sodium chloride, and distilled water, to give a yield of 900-1100 micrograms/mil of streptomycin.
