Abstract: 551,613. Knitting. NATIONAL SILK HOSIERY MILLS, Inc. May 24, 1941, No. 6679. Convention date, May 24, 1940. [Class 74(ii)] A full-fashioned stocking having an upper heel portion widened by the addition of edge loops, as distinguished from widening by transference of loops from one needle to another, and a narrow lower heel portion, has the instep portion of the sole knitted with a tighter stitch than the heel so that the instep portion tends to cling to the foot. The widening of the upper heel portion may be effected as described in Specification 551,615. The heel may be reinforced as shown in Fig. 10, by using a splicing yarn 34 terminating inwardly of the edge to provide marginal areas 32 of lighter and more elastic fabric extending along the edges. The narrowing in the lower heel portion may be made so as to provide narrowing lines either parallel to the edges of the blank, or parallel to the wales in the centre of the blank, or as shown in Fig. 2b, two sets of fashioning lines K L, K' L<SP>1</SP> may be provided defining areas in which the wales are differently inclined to the wales in the centre of the blank. The rear portion of the instep may be so narrowed as to provide fashioning lines L M inclined to the edge of the blank. The upper heel portion may be so widened that the edge first assumes a relatively small inclination to the wales, then assumes a greater inclination, and before reaching the zone of maximum width is again inclined at a less inclination to the wales.

Title: An improved process for converting alkali salts of phenylalkyl barbituric acids into stable calcium compounds
Filed: 1935-03-05
Abstract: Stable calcium salts of phenylalkyl-barbituric acids are prepared by treating the corresponding alkali metal salts in the solid state with crystallized (i.e. hydrated) calcium bromide and mixing the product with wholly or partially dehydrated calcium bromide.  If desired, the crystallized and dehydrated calcium bromide may be added at the same time, whilst other anhydrous bromides, such as potassium, magnesium or strontium bromide, may also be added.  The products are useful as sedatives and soporifics.  According to the examples; (1) sodium phenylethyl-barbiturate is triturated whilst warming with calcium bromide tetrahydrate, carbon dioxide of the air being excluded; the product is mixed with dehydrated calcium bromide; (2) sodium phenylallyl - barbiturate is treated with crystallized calcium bromide and the product mixed with dehydrated calcium bromide and potassium bromide.  The sample furnished under Sect. 2 (5) is prepared by grinding sodium phenylethyl-barbiturate with calcium bromide hexahydrate and mixing with dehydrated calcium bromide and dehydrated strontium bromide.ALSO:In the preparation of calcium salts of phenyl-alkyl-barbituric acids from the alkali metal salts and hydrated calcium bromide, the product is stabilized by admixture with wholly or partially dehydrated calcium bromide or by using a mixture of the hydrated and dehydrated calcium bromide for the preparation. Other anhydrous bromides, such as potassium, magnesium or strontium bromide, may also be added.  The products are useful as sedatives and soporifics.  According to the examples: (1) sodium p phenylethyl-barbiturate is triturated with calcium bromide tetrahydrate and the product mixed with dehydrated calcium bromide; (2) sodium phenylallyl-barbiturate is treated with crystallized calcium bromide and mixed with dehydrated calcium bromide and potassium bromide.

Filed: 1936-03-10
Abstract: 473,276. Converting. BLUMLEIN, A. D. March 10, 1936, No. 7206. [Class 38 (ii)] Distortion of the current waveform from sinusoidal in the A.C. supply to a rectifier is avoided by making the impedance of the input circuit of the rectifier large for all frequencies except the fundamental. This is effected by connecting in series in the supply to the rectifier 4, 5 a series resonant circuit 12, 13 tuned to the fundamental. The condenser size mav be adjusted to compensate for the leakage inductance of the transformer and for the inductance of the A.C. circuit. The trans; former may be arranged to have sufficient leakage inductance to render an additional inductance 12 unnecessary. The Specification states that when used with hot-cathode valves the invention reduces the amount of cathode disintegration.

C. engine includes a lever 17 displaceable with a throttle plate 25, a moveable valve member 45 regulating flow from supplementary fuel and air sources 35, 39 into an intermixing chamber 37 connected by a conduit 43 to an intake manifold 13, linkage means connecting valve member 45 to lever 17 and including a time delay which upon opening actuation of lever 17 acts as a solid link and following actuation lengthens as a function of time permitting the valve member to return to its prior position without return movement of lever 17 and plate 25. With the engine idling and partly warmed coolant the diaphragms 69 and 71 are shown in the solid line position. When throttle plate 25 is opened to position 25' the diaphragm 71 is displaced to position 71', check valve 83 closes and a partial vacuum is created in chamber 73 which displaces diaphragm 69 to position 69' thereby lifting valve member 45 to position 45' and increasing mixture supply to intake manifold 13. Immediately following throttle opening the vacuum decay device 19 is tensioned by springs 65 and 79. Air bleeds via passage 83 into chamber 73 until the diaphragms 69, 71 reassume their preactuation positions. When throttle valve 25 is again closed the check valve 81 reopens to allow unrestricted collapse of chamber 73. In a modification a spring may assist the return of diaphragm 71. In Fig. 3 (not shown) the fully warm coolant causes a thermostat piston 55 to be fully protracted thereby closing the valve member 45 during engine idling to prevent any fuel enrichment. Upon throttle actuation the supplementary fuel/ air system functions as described above. In Fig. 1 (not shown) the elements are positioned for idling when the coolant is cold.
