Title: Measuring parameters of devices implanted in organisms
IPC: A61F2/72
Filed: 1972-03-17
Abstract: 1363371 Electro-medical apparatus L'ELECTRONIQUE MEDICALE SERDAL SA 17 March 1972 [19 March 1971 28 April 1971] 12660/72 Heading G1N A parameter which characterizes the operation of a device implanted in a living organism and of an organ of the organism is converted into a potential difference which is converted into pulses of coded frequency, the pulses being transmitted through the skin of the organism to a receiver and converter. As shown in Fig.1, the current supplied by a pacemaker 2 to the heart 3 of the organism is converted into a voltage (across resistor 1), the voltage being applied to a voltage-to-frequency converter 4 whose output signal is applied to a pair of electrodes 6, 7 positioned beneath the skin 8 of the organism. The signal transmitted by electrodes 6, 7 are picked up by electrodes 16, 17 connected to a frequency-to-voltage converter 5 and a display 12. Alternatively the voltage supplied by batteries to the pacemaker 4 may be the monitored parameter, Fig. 2 (not shown). The electrode 6 may be a ring electrode, and the electrode 7 a circular disc positioned inside the electrode 6, Figs. 3 and 4 (not shown). The threshold of stimulation of the heart by the pacemaker may be determined, either by monitoring the current supplied by the pacemaker to the heart as the voltage supply to the pacemaker is decreased from a maximum or by monitoring the voltage supply as it is decreased from a maximum, Figs. 6 and 7 (not shown). In these methods a magnetically operated switch is operated so that the pacemaker 2 and converter 4 are disconnected from their constant voltage supply and connected to a series of photo-cells positioned beneath the skin, the cells being illuminated through the skin by a light source whose intensity is varied to thereby vary the voltage supply to the pacemaker. By monitoring the operation of the heart as the voltage supply is decreased, the threshold of stimulation may be determined.

Patent GB-561903-A (GB)
Title: Improvements in or relating to the production of vitamin concentrates
Filed: 1942-09-11
Abstract: Vitamins A and D are recovered from concentrates derived from the unsaponifiable fraction of a fish or fish liver oil by forming a solution of the concentrate in an aliphatic or alicyclic hydrocarbon, extracting the vitamin A by means of an aqueous solution of a lower aliphatic water miscible solvent containing sufficient water to inhibit the solution of the vitamin D, esterifying the vitamin D in the hydrocarbon solvent and extracting it by means of a lower aliphatic water miscible solvent.  The concentrates are preferably first freed from cholesterol, for example by freezing out from solutions in methanol, ethanol, isopropanol, methyl, acetate, methylformate or ethylformate.  Specified hydrocarbon solvents mentioned for dissolving the concentrates freed from cholesterol are: pentane, hexane, heptane, octane, nonane, petroleum ether, cyclohexane and methylcyclohexane and aqueous solutions of methanol, ethanol, isopropanol, diacetone alcohol, acetic acid and mixtures thereof may be used for extracting vitamin A.  For the esterification of vitamin D, aromatic anhydrides, e.g. benzoic, phthalic and naphthalic anhydrides, aromatic acylhalides, aliphatic dicarboxylic anhydrides and halides, e.g. adipic, sebasic, and succinic anhydrides and chlorides may be used.  The same solvents that are used for the extraction of vitamin A, may be used for the extraction of vitamin D esters but they are used in higher concentrations.  Pyridine, quinoline and piperidine may be used as esterification catalysts.  In an example, a cod liver oil concentrate, after freeing from cholesterol is dissolved in hexane and then extracted first with 90 per cent methanol and then with 85 per cent methanol.  The combined methanol extracts are washed with hexane and freed from solvent.  The hexane extracts are evaporated, dissolved in pyridine and esterified by means of phthalic anhydride.  Petroleum ether is added and the pyridine extracted with aqueous methanol and acetic acid.  Vitamin D esters are removed by extracting with 95 per cent methanol and saponified with alcoholic potash.  The products may be used to fortify foods or mixed with activated ergosterol, cholesterol or 7-dehydro cholesterol.  Specification 550,845 is referred to.

Title: Improvements in or relating to the feeding of tobacco to cigarettemaking machines
IPC: A24C5/39
Filed: 1936-05-08
Abstract: 470,523. Cigarette-making machines. GOOCH, C. W. May 8, 1936, No. 13084. Convention date, May 31, 1935. [Class 130] A continuous or very long tobacco rod is produced in a limited space by showering shredded tobacco uniformly into a curved or spiral channel over substantially the entire length of the channel and the shreds are formed gradually into a rod in the channel by accumulation from the shower. As shown, tobacco from a carded feed roller 3 is showered by a picker roll 37 over a rotary distributing cone 53 into a spiral channel formed by a stationary coil 52 and a rotating disc 40 closing the bottom of the channel. The coil 52 is carried by radial arms 51 on a core 50. The disc 40 is formed with radial grooves to move the tobacco along the channel and is driven through gearing 45, 46, 48 from the shaft 44 of the cone 53, so that the disc and the cone rotate at different speeds. The cone is formed with vanes v having scrapers 54 in light contact with the upper edge of the coil 52. From the outermost turn of the coil, the tobacco is guided on to a moving web W by guides 59, 60, 63, a rotary scraping wheel 64 being provided between the guides 60, 63. Tobacco is fed to the roller 3 from a hopper 78 by a roller 8 having ratchet-like corrugations extending along its full length. The roller 8 is intermittently rotated through gearing 11 .. 14 from a ratchet wheel 10 driven by a pawl 15 on a lever 16 pivoted upon the shaft 9 of the roller 8. A block 17 adjustable in a slot in the lever 16 is pivoted to a connecting-rod 18 reciprocated by an eccentric 19 through a strap 20 and a lever 21. A roller 23 on the rod 18 rests on a bar 24, hinged at one end to a stationary bracket 25 and supported at the other end through a link 26 connected at its lower end to a segment 27 pivoted on a rod 28. The segment 27 forms part of a curved housing concentric with the rollers 8, 3, and a spring 29 allows the segment to yield in accordance with the pressure of tobacco in the housing. The resulting movement of the bar 24 adjusts the block 17 in the slot of the lever 16 and consequently adjusts the stroke of the pawl 15 to keep a constant feed of tobacco through the passage R. A concave shield 36 attached to the lever 21 pushes back into the passage R any excess tobacco picked up by the teeth of the roller 3, and a levelling roller 2 is provided. The Specification as open to inspection under Sect. 91 describes and illustrates diagrammatically a method of preparing tobacco for cigarette making in which the tobacco is cleaned, shredded, dried, &c. and formed into charges of uniform density and size or cross-section. The charges are separated and showered into a device for forming a tobacco rod, which may be the mechanism described above. This subject-matter does not appear in the Specification as accepted.
