Title: Improvements in or relating to counting or display devices
Inventor: TRUSLOVE DAVID JAMES
IPC: F15C3/00
Filed: 1963-02-20
Abstract: 1,055,313. Fluid-operated counters. INTER. NATIONAL BUSINESS MACHINES CORPORATION. Feb. 6, 1964 [Feb. 20, 1963], No. 6846/63. Heading G4P. A counting or display device comprises a ring of cavities interconnected with one another through constricted passages, one or all but one of said cavities being filled by a globule of mercury or other high surface-tension fluid, and includes electric or fluid means for indexing the liquid globule round the ring. As shown in Fig. 2 a steady fluid pressure is applied on a line or duct 12 and counting or indexing pulses are received on a line 14. The pulses on the lines 140, 141, 142 etc., which pass into cavities such as 0, 2 which do not at that time contain a mercury globule, pass directly to an outlet 150, 152 etc., to switch the corresponding jets of fluid issuing from the lines 120, 122 etc. from a direction in which they pass down lines 170, 172 etc. into the corresponding cavity 0, 2 etc. to vent outputs 160, 162 etc. The pulse on line 14, is interrupted by the presence of the globule 11 and thus does not pass to the outlet 15, thus the jet from the line 121 continues to pass down line 171 to cavity 1 and thus the mercury globule is indexed to the next cavity. In a modification (Fig. 4, not shown) all but

Title: Apparatus for trimming and spreading grain, ore and the like
IPC: B65G69/00
Filed: 1929-03-04
Abstract: 327,537. Kroef, J. W. March 4, 1929. Collapsable and like framework for endless - chain pushplate conveyers and elevators, directing and adjustably supporting; idler rollers. -Apparatus which may be suspended in a ship's hold for trimming cargo comprises a framework 23, 23<1> provided with an extending flexible frame A movable in a guideway 7 so that it can project beyond the base 23, as shown in Figs. 6, 8. The frame A is suspended from a spindle 19 which is moved in vertical guides 17 by a cable 21 and winch 20. The frame A consists of plates or planks 1, 2 hinged together as shown in Figs. 1 and 4, the hinges being normally locked but released manually or automatically as they pass points where the extended framework changes direction. Automatic release is effected by engagement of a locking pawl with a fixed abutment 16 as described below. The hinges are released manually to enable the plates 1, 2 to resume their normal relation after passing such points, and also to enable the plates to pass the bend 7<1>. Endless chains 35 pass round sprocket pinions 24 on the spindle 19, 25 on the base 26 of the extending frame A and a driving sprocket 28 on the base, and the chains carry transverse rakes, forks or paddles 34. The chains also engage guide rollers 27, 29, 30, the two latter moving down with the spindle 19. The apparatus is suspended by the eye 33 and the free end of the frame A may be diverted, as shown in broken line in Fig. 8, the chains engaging additional guide rollers 36, 37. As shown in Figs. 1 and 4, the plates or planks 1, 2 are connected by hinges 3, the movement of the plate 1 being limited in one direction by the extension 4 of the plate 2 and in the other by the stop 5. The plate 2 carries an internallytoothed sector 10, engaging a pinion 11 carried by a sector on the plate 1. The pinion is normally locked against rotation by a pawl 12 held in engagement by a spring 14 and the hinge is therefore locked. When the hinge moves past an abutment such as 16, the pawl is momentarily freed, a radial arm such as 15 on a disc 13 on the spindle of the pawl engaging the abutment as it passes. The plates 1, 2 are provided with transverse bars 6 which extend laterally into the guideways 7.

Title: Methods of producing high density titanate ceramic bodies
IPC: C04B35/491
Filed: 1956-03-06
Abstract: High density dielectric ceramic bodies are produced from raw material consisting of (1) oxidic barium and titanium in amounts equivalent to at least 81% by weight barium titanate in the ceramic body or (2) oxidic lead, zirconium, and titanium in molar ratios of zirconium to titanium between 40 : 60 and 60 : 40 and constituting as lead zirconate titanate at least 96% by weight of ceramic body, by firing to a temperature within the maturing range for the material and not less than 95 DEG C. higher than the lowest temperature of this range, while maintaining a partial pressure of oxygen greater than 300 millimetres of mercury during substantially all of the period extending from the time the temperature reaches the lower limit of the maturing range to the time the temperature starts to decrease. The maturing range extends from a temperature no more than 10 DEG  to 15 DEG C. below the temperature at which firing can be effected in two hours up to a temperature at which extensive vitrification occurs.  The barium titanate ceramic bodies may contain up to 15% by weight of calcium titanate, and up to 4% of other substances, e.g. titanium (in excess of that required by barium and, if present, calcium titanates), sodium, aluminium, strontium, zirconium and silicon, as oxides or salts.  For a barium titanate ceramic raw material containing 0,6% to 1,0% by weight of sulphur, about the same weights of oxidic strontium and excess titania, and about 1% by weight of other impurities such as alumina, soda, and silica, the maturing range is from 1300 DEG  to 1500 DEG C.  The effects of firing this raw material in oxygen at temperatures of 1350 DEG C. and 1450 DEG C., and in dry hydrogen at 900 DEG C. to 1200 DEG C. followed by firing in oxygen, are compared.  In the preparation of the lead zirconate titanate ceramics firing may be effected in a closed tube with the bodies to be fired at the end inserted in the furnace while the other cool end is packed with lead monooxide, lead zirconate or lead zirconate titanate thereby maintaining an atmosphere of lead monoxide (which is otherwise volatilized and lost) during firing.  Instead of filling the tube with oxygen, lead dioxide may be employed to provide both this and the lead monoxide. Specification 717,520 is referred to.

Title: Improvements to systems for data transfer between direct access memory and magnetic drum or similar storage memory
IPC: H04L12/54
Filed: 1969-02-12
Abstract: 1,210,337. Drum/core transfer system. INTERNATIONAL STANDARD ELECTRIC CORP. 12 Feb., 1969 [16 Feb., 1968], No. 7654/69. Heading G4C. A system for transferring data between a drum store and a core store is characterized in that (a) To each sector of a track on the drum is uniquely associated a one-word store within the core store-these one-word stores being collectively referred to as a " sector table "; (b) In each one-word store of the sector table an address is stored of the position within the core store that a transfer instruction relating to the drum sector corresponding to the oneword store will be found; and (c) As each sector of the drum becomes accessible, the corresponding one-word store in the sector table is read-out to cause the transfer instruction relating to that sector to be read out and implimented.  As described, whenever a transfer instruction occurs during the performance of a programme, it is read into a particular segment in the core store, each segment being large enough to hold several transfer instructions and corresponding to the sector of the drum that is involved in the transfer. Thus, each of these segments holds a queue of transfer instruction relating to the associated sector on the drum. The address of the first instruction in the queue is stored in the associated one-word store of the sector table. As the drum rotates a sector counter and a word counter indicate the sector and word currently accessible. Each time the sector counter changes, the sector table is consulted to find the address of the first transfer instruction in the core store that is awaiting implimentation. This instruction is read out and immediately obeyed-this being possible because the drum is necessarily appropriately positioned. At the end of the transfer, the sector table is up dated so that it holds the address of the next transfer instruction.
