Title: Power divider and planer magic tee
IPC: H01P5/10
Filed: 1975-03-13
Abstract: 1466811 Power-dividing junctions POST OFFICE 13 March 1975 [29 April 1974] 10504/75 Heading H1W Power dividers and magic-T's are made from transmission lines formed in a single conductive layer on a dielectric substrate. The lines are of the kinds known as "slot-lines" and "coplanar lines"; The Figure shows a conductive layer entirely covering a substrate except for the etched slots which form the various lines. Thus, a co-planar line is formed by (parallel) slots 60, 62 which gradually diverge to form two slotlines 54, 56. Input energy to the co-planar line is divided co-phasally between the slot lines. The latter also form a T junction with a slot line 58 in such a manner that input energy to the line 58 is divided in antiphase between the lines 54, 56. It is apparent from the phase relation strips, that the line 58 provides the "E" arm and the line 60, 62 the "H" arm of a magic- T.

Four angles back to back or a T-section may be similarly bent. If the bend is to be effected the opposite way the groove is formed in the lower rolls instead of in the upper roll. In bending strip R, Fig. 5, on edge, a groove p<SP>1</SP> is left between sections J and K. The width of the grooves and the position of the rolls for various radii of curvature of the bend to be effected may be indicated by scales.

Abstract: 1339032 The antibiotic rabelomycin E R SQUIBB & SONS Inc 23 April 1971 [18 June 1970] 11046/71 Heading C2A The novel antibiotic rabelomycin of Formula I is obtained by aerobically cultivating a new strain of Streptomyces olivaceus (ATCC. 21549) in an aqueous nutrient medium containing an assimilable carbohydrate and an assimilable organic nitrogen source. The rabelomycin may be isolated from the mycelium and the fermentation broth by filtering the culture and extracting the filter cake with methanol, evaporating off the methanol to leave an aqueous residue and combining this with the culture filtrate. The pooled mixture is then extracted with ethyl acetate, the extract concentrated to a syrup and subjected to counter current distribution in MeOH : H 2 O : hexane (3 : 1 : 4, v/v/v), and the active fractions are evaporated to dryness. The resulting crude rabelomycin may be purified by chromatography on DEAE-cellulose, then on silica gel and final recrystallization from benzene-methanol. Pure rabelomycin is a yellow crystalline solid, M.P. 193‹ C. (decomp.); analysis C = 67À17, H = 4À48. 0 = 28À35; empirical formula C 19 H 14 O 6 ; optical rotation [α] D  = -102 Œ 10 degrees (C = 1 in (HCl 3 ); U.V. absorption in MeOH or 0À02 N.HCl in MeOH: #max at 228 nm (# = 26,600), 267 nm (# = 28,800) and 433 nm (# = 8,000), and in 0À02 N.NaOH in MeOH: #max at 258 nm (# = 26,200), 282 nm, shoulder (# = 13,100), 325 nm (# = 8,900) and 507 nm (e = 7,500), which is soluble in alkanols, acetone and chloroform, and insoluble in water and petroleum ether. Dehydration of rabelomycin gives the novel compound dehydrorabelomycin having the Formula II The dehydration may be effected by treatment with a concentrated mineral acid e.g. HCl or H 2 SO 4 . Rabelomycin and its dehydro derivative may be converted to mono-, di- or tri-esters (e.g. rabelomycin di-acetate) by treatment with one, two or three equivalents of an acylating agent such as an acid chloride or anhydride, and also to base salts of alkali metals or alkaline earth metals (e.g. rabelomycin sodium salt).

Abstract: 249,346. Hardesty, B. F. April 28, 1925. Fixed-chamber apparatus, varying quantity measured in and valve systems, printing, recording and counting apparatus for.-The lift valve 65 by which discharge from the measuring chamber 31 is controlled is opened by a hand lever 84, and is closed automatically when a predetermined volume has been delivered by a solenoid 92. The solenoid is energized when a mercury switch 93 is tilted by an arm 99 which is positioned initially by a selective device. Ticket-printing, recording, and counting mechanisms are provided. Specifications 249,389, 249,890, and 249,391 are referred to. The measuring-chamber 31, which is of definite capacity, and may have a transparent wall, is filled by a pump driven by an electric motor 39, under the control of a press-buttonswitch 44<a>, or the automatic control of a float. A spreader 46 deflects the entering liquid, e.g. petrol from a float 45, and surplus liquid is led awa.y by an overflow pipe 43. The float 45 is con. nected by a chain 48 with a weighted wheel 55 on a control shaft 60 which co-operates with the mercury switch controlling device, and also carries the printing type wheels 123. The mercury switch 93 is pivoted on a pin 94, Fig. 14, and is rocked to complete the circuit of the solenoid 92 by an arm 99 on a selector sleeve 100. This sleeve is pressed by a spring 110 so that it is normallv clutched bv teeth 108. 109 to the shaft 60, and follows its movement under the influence of the float 45. It is pulled out and rotated to determine the quantity to be delivered by a sleeve 116 having pins 118 which engage its roughened surface 117. This sleeve is actuated by a key engaging a cross pin 121. A pointer 101 indicates on a scale 103. Fig. 18, the volume which the apparatus has been set to deliver, and a pointer 105 on the shaft 100 indicates on a scale 104 the quantity which has been delivered. The hand lever 84 on the shaft 75 opens the valve 65 through a cam 78, Fig. 5, which is tripped to close the valve after the required quantity has been delivered when the solenoid 92 is energized. The armature 91 of the solenoid 92 is extended downwardly and engages the head 185 of the stem 183 of the printing platen 127, between which and the type wheels 123 on the shaft 60 two paper strips 128, 129 are fed by geared rollers 137, 138, Fig. 8. The upper roller is mounted in a releasable, spring-pressed carrier 162, and the lower roller is rotated to feed a printed ticket through the opening 139 by a hand lever on its shaft. The lower strip 129 is retained as a record in the machine and is wound on a roller 140 which is driven from the feed roller 138 by a belt 152. Inking ribbons 174 are fed by hand between the paper strips from reels 175, 178. The type wheel 123 is arranged to print volume delivered, price, and total cost. A counter 188 is actuated by a shaft 189 driven by bevel gearing from the shaft 60, and registers the total volume delivered.

Limbs, artificial.-Artificial limbs and other orthopµdic devices are formed by covering a cast of the particular body portion with a layer of so-called liquid wood which is allowed to solidify and is then detached and securely inserted into a main shell or sleeve. As shown, an artificial leg is formed by moulding the liquid wood b around a plaster cast a, the shell thus obtained being slit longitudinally and secured in the outer sleeve c which may be of wood, leather, metal, vulcanite, fibre or other material. The liquid wood employed usually consists of wood flour and an adhesive such as lime-glue or a solution of nitro-cellulose with acetone. The sleeve c may be in one piece, but preferably it is divided longitudinally.
