Title: Improvements in or relating to supply cathodes for electrical discharge tubes
IPC: H01J9/04
Filed: 1966-04-21
Abstract: 1,139,766. Cathode materials and processing. SIEMENS A.G. 21 April, 1966 [22 April, 1965], No. 17395/66. Addition to 1,120,969. Heading H1D. The dispenser cathode as claimed in the parent Specification, in which a supply chamber containing a charge of barium oxide is covered by a porous emissive-substance carrier, has applied to the surface of the carrier facing the supply chamber a coating of an oxide of aluminium, beryllium, hafnium, magnesium, or zirconium, or of titanium or thorium dioxide, or of niobium trioxide, or vanadium tetroxide, or of niobium pentoxide, the coating being a thermally converted hydroxide layer. The coating tends to equalize the pore diameter in the carrier and so regularizes the barium evaporation, and also inhibits the penetration of solder into the carrier. The hydroxide layer in the form of a voluminous colloidal gel may be precipitated from a suitable salt on to the carrier surface and then thermally reacted and sintered to convert it to the oxide. The layer may be formed by lightly pressing the carrier against a moist gel film so that plastic hydroxide gel penetrates the pores of the carrier, this being aided by a vacuum the other side of the carrier, or the carrier may be moistened and then exposed to a jet of a vapour of a metal alkyl compound to form the hydroxide. The above oxide coatings have various melting points and are chosen according to the highest temperature the cathode is likely to experience during manufacture and operation. Any surface of the carrier not to be coated may be masked by a template or a removable layer of nitrocellulose or a depolymerizable synthetic resin, or the surface coating may be machined off.

Title: Shift register
IPC: H04M11/00
Filed: 1971-11-03
Abstract: 1342845 Shift registers GAMON-CALMET INDUSTRIES Inc 3 Nov 1971 [31 Dec 1970] 17413/73 Divided out of 1342844 Heading G4C A shift register arrangement comprises a plurality of latch circuits 149a-149f connected in series, each responding to a first control level to provide a conductive path between its input and output, and to a second control level to provide a non-conductive condition between input and output, and to a change from first to second level to maintain the prevailing output signal condition despite subsequent change in the input. As disclosed, each latch holds four parallel bits. Data to be stored is inserted at the left, each four-bit character being accompanied by a pulse at X. The first pulse at X sets the first stage 148a of an auxiliary shift register 148 in response to a shift pulse at 162 produced via delay 161 and gate 15. The set state of 148a enables latch 149f to store the character. The second pulse at X results in the set state of 148a being shifted to stage 148b and in stage 148a being set also, so that the second character is stored in latch 149e, and so on. To unload the arrangement (at the right), pulses are applied at Y, shifting the auxiliary shift register 148 via gate 15 and line 162, zeroes being entered at X so that progressively more of the register 148 is reset from the left. The state of latch 149f is sensed at the output, then as stage 148a is reset, latch 149f is rendered conducting to permit the state of latch 149e to be sensed at the output, and so on. The length of the store can be effectively shortened, as by a tap at 121.

Gear 42 may be locked to the input shaft by a clutch member 124 slidably keyed to the shaft and having internal teeth 126 which can engage teeth 128 on the gear 42. Gear 44 drives the foremost of two rear axles through a conventional single speed differential gear set 52 and gear 42 drives the rearmost of the two axles through a two-speed differential gear set 70 having a direct drive and an underdrive; it comprises a planetary gear system 76, the sungear 78 of which is axially shiftable between two positions in one of which the planetary system is locked. The gear 78 is moved by means of a yoke 82 which engages its shaft 80. The yoke is operated by a reversible electric motor 84, as disclosed in Specification 616,533 the direction of rotation being determined by a manually actuated switch 90. An interlock is provided between the motor 84 and the differential gear set 32 so that the differential gear set can only be locked when the rear axle is in its high gear ratio and hence identical in ratio with the foremost rear axle. When the rear axle is in low ratio the clutch member 124 is locked in its non-operated position by the armature of a solenoid .108 which engages a member 118 connected to the slidable clutch member 124. When the switch 90 is operated to change the ratio of the rear axle to high the solenoid is energized to release the clutch member so that the differential gear set 32 can be locked. It is also arranged that the motor 84 cannot be operated to change to low ratio until the differential gear set 32 is unlocked since it is supplied with current through a switch 132 the contacts of which are operated by the member 118 so that they are only made when the differential gear set 32 is unlocked.
