Title: Electronic camera tubes
IPC: H01J29/45
Filed: 1971-03-05
Abstract: 1382824 Coating silicon with glass ENGLISH ELECTRIC VALVE CO Ltd 12 Jan 1972 [5 March 1971] 6116/71 Heading C1M [Also in Division C7 and H1] A target electrode of a camera tube comprising a silicon substrate with an array of diodes on one surface, an oxide layer in the interstices of the diodes and a resistive layer covering the diodes and the oxide ; is characterized in that the resistive layer is of semi-conducting glass. In one example, a mixture of barium metaphosphate glass and molybdenum powder are placed in a molybdenum boat and heated in vacuo to form volatile products which condense on the target as a film 0À1 microns thick of glass containing molybdenum to give the required conductivity of 10<SP>12</SP>-2X10<SP>13</SP> ohms/ square; if the resistivity is too high, molybdenum powder and molybdenum tri-oxide are added to the boat for the deposition of subsequent layers. The target is then baked at 400 C. in an atmosphere of cracked ammonia. In another example where the target is required to withstand soft X-rays produced during operation of the tube in which it is used, the glass should contain tungsten and may be evaporated from a mixture of silicon powder and tungsten powder placed in a tungsten boat evaporator. When the target must withstand alkali metal vapour, as when used in a bombardment induced conductivity type of tube, the glass should contain titanium and may be evaporated at the target by electron bombardment of a mixture of titanium dioxide and silica. The basic glass material may be any known composition.

Abstract: 367,193. Straight-bar knitting- machines. HOSIERY MACHINE CORPORATION, Cumberland, Rhode Island, U.S.A.-(Assignees of Miller, M. C. ; Cumberland, Rhode Island, U.S.A.) March 2, 1931, No. 6485. Convention date, March 3, 1930. [Class 74 (ii).] Automatic welt-turning mechanism applicable to the Cotton type whereby the welt may be knitted and the fabric continued without stopping the knitting comprises welt hooks 98 slidable in an aluminium carrier 100 and transfer elements or cheeks 102 fixed in the carrier. The cheeks are formed with pointed tips which are bent so as to come together in pairs. The hooks are projected from the carrier as a unit by a cam bar 114 moved by a slotted cam plate 116. Supporting members 134 pivoted to the carrier 100 are grooved at 138 to receive the welt take-up bar 132. After the welt fabric has been started the operator depresses the members 134 into the position shown in Fig. 10, where they are held by spring latches, and places the bars 132 in the grooves 138. At a later stage the operator carries the bars forward and places them in lower grooves where they are held by the tension of the fabric. A suspender or take-up strap is secured to each end of the take-up, which is gradually retracted beneath the carrier as shown in dotted lines. The carrier is suspended from a track by rollers and when advanced to take the initial loops of the welt it is positioned by cams, which register the welt hooks accurately between the needles. The needles are also brought abnormally close to the sinkers so that long loops can be sunk. The needles are also given an abnormal lateral movement away from the pressers to bring them into line with thickened portions 280 of the knocking-over bits. When the welt is completed the carrier is advanced under control of a pattern chain and the needles are again moved abnormally to co-operate with the transfer elements on the carrier. For advancing the welt hook carrier a pair of thrust members 184, one at each end of the carrier, pivoted to arms 186, are operated by rocking a shaft 188. The forward ends of the members 184 are supported by pins 194 riding on a track 174 and are shouldered to engage abutments in plates 192 secured to the carrier. The shaft 188 carries an arm 198 loose thereon and provided with a forked extremity on which are mounted cam rolls. Fixed on the shaft 188 is an arm 196 with a handle 214 by which the carrier is advanced into operative position manually. At the same time, the arm 196 is held against the arm 198 by the engagement of a spring-pressed plunger 210. The carrier is then operated by the cam shaft 52 in accordance with the configurations of cams placed in the track of the cam rolls on the arm 198.

Title: Improvements in the crystallization of dextrose
IPC: C13K1/10
Filed: 1935-03-04
Abstract: In producing crystallized dextrose from starch converted solutions by adding quantities of solution at intervals to the contents of a crystallizer, the supersaturation of the massecuite is lowered at an intermediate stage of the crystallizing operation by adding solution of a density lower than that of the other filling quantities.  The yield of crystals is thereby improved. In an example liquid was added in instalments of 476 pounds, 1823 pounds, 9190 pounds, 1725 pounds, 20,926 pounds and 74758 pounds, to a crystallizer.  All of the quantities are approximately of density 40 Baume except the fourth which is of density 30 Baume and serves to lower the supersaturation. Specifications 232,160, [Class 32], and 366,974 are referred to.
