Title: Improvements in pectin products and the process of making same
IPC: A61K31/43
Filed: 1947-11-25
Abstract: A streptomycin-pectin compound is obtained by mixing aqueous solutions of the two components and precipitating the compound by the addition of alcohol.  The streptomycin may be employed in the form of its sulphate, hydrochloride or phosphate.  Specification 642,385, [Group VI], is referred to.ALSO:A medicinal pectin product is prepared by forming a stable suspension in a vegetable oil of a mixture of dry pectin of a particle size small enough to pass through a 20 gauge needle and a solid pharmaceutical agent having a particle size of 50-100 microns, the viscosity of the oil being adjusted by adding more than 4 per cent of an acid-free hydrogenated oil so that settlement does not occur on standing and all the ingredients containing not more than 1 per cent moisture.  Alternatively, instead of adjusting the viscosity of the oil, the particle size of the pectin is limited to between 0.1 and one micron. Preferably a mixture of sesame oil or peanut oil and hydrogenated peanut oil is employed. Specified pharmaceuticals are antibiotics such as penicillin X, penicillin F, penicillin G, penicillin dihydro F, penicillin K, penicillin sodium or calcium bacitracin, lumycin and subtilin. streptomycin phosphate or hydrochloride and streptomycin calcium chloride trihydrochloride drugs such as insulin, epinephine, ephedrine; hormones such as estrin, estradiole and stilbesterol; and vitamins such as folic acid, vitamin B1 complex; ascorbic acid and liver extract. According to one example, alcohol and sesame or peanut oil are added in succession to an agitated aqueous solution of pectin. the resulting suspension of pectin is distilled under reduced pressure at 85-95 DEG C until all alcohol and water are removed and sodium crystallin penicillin is added to the resulting suspension of pectin in oil.  According to a second example, sesame or peanut oil is emulsified with an aqueous solution of pectin, water is removed by distillation and sodium penicillin is added to the resulting suspension.  According to a third example, dried finely-divided pectin and dried penicillin are milled together while maintaining a moisture content of below 1 per cent and a heated mixture of sesame oil or peanut oil with hydrogenated peanut oil is added. Streptomycin and pectin in solution in water forms a clear, easily injectable solution.  Specification 642,385 is referred to.ALSO:Pectin of fine particle size is obtained by mixing the pectin with small pieces of dry ice and when it has become chilled, grinding it in a hammer mill and passing the ground product through a mesh screen.  Specification 642,385, [Group VI], is referred to.

Title: Terrain elevation or altitude representation system
Inventor: SELVIN MANUEL
IPC: G01S13/935
Filed: 1966-07-13
Abstract: 1,141,223. Terrain avoidance radar. UNITED AIRCRAFT CORP. 13 July, 1966, No. 31400/66. Heading H4D. In an automatic terrain avoidance system comprising a forward-looking Az-scanning pulse radar there is produced during each range scan a time-varying altitude voltage H, Fig. 4, representing the true altitude profile of the terrain which is modified by decreasing its amplitude as a function f(D) of range D to give an effective profile voltage H<SP>1</SP> such that elevations at a greater distance are of less significance than those which are close. The maximum value H<SP>1</SP>max of the voltage H<SP>1</SP> is selected and increased, Fig. 2 (not shown), as a function f(A) of the instantaneous Az direction A, of the aerial relative to the direction C of a desired destination to give a voltage H<SP>11</SP>, Fig. 5, and the aircraft is automatically headed in the direction A<SP>1</SP> corresponding to the minimum Z<SP>1</SP> of the variation of H<SP>11</SP> with A during an Az scan cycle so that the resultant aircraft heading is a compromise between the direction of least effective terrain elevation and the destination direction. The altitude control of the aircraft is effected in a known manner (not described). As shown in Fig. 1 a true terrain elevation voltage produced by phase comparison at 32 of the signals received by two vertically spaced Rx<SP>1</SP> 14, 16 is converted to the true altitude voltage H by multiplying at 52 with a p.r.f. sawtooth from a generator 46 and the effective altitude voltage H<SP>1</SP> is produced by subtracting at 56 a modifying signal f(D) from a function generator 54. The signal H<SP>1</SP>max is selected by a circuit 60 ... 66 and the signal H<SP>11</SP> is obtained by adding at 90 an Az modifying signal f(A) from a function generator 86. A circuit 92 ... 102 then produces a pulse P, Fig. 5, at the instant in the Az scan cycle corresponding to the minimum Z<SP>1</SP> of the H<SP>11</SP> curve and the pulse P is applied to a gate 104 together with the instantaneous aerial Az Z from a generator 28 coupled to the aerial Az drive to give an error signal corresponding to the angle Z<SP>1</SP> between the direction of Z<SP>1</SP> and the aircraft heading, said error signal being applied to the heading control 110. The input A (instantaneous aerial direction relative to destination direction) to the Az modifying signal generator 86 is given by A = C - B, where C (destination direction) is obtained from a computer 74 and B (true instantaneous aerial direction) is given by B = 6 + Z, where 6 is the A/C heading from a gyro 72. The radar 10 is stabilized in pitch and roll by a vertical gyro 18.
