Title: Improvements in data handling systems
Inventor: GRANITO GERRY DAVID
IPC: G06F13/22
Filed: 1963-10-03
Abstract: 989, 867. Electric digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 3, 1963, No. 38995/63. Heading G4C. A storage device receives massages, each including destination identifying data, assembles them in selected locations in an addressable store, scans a plurality of transmission circuits associated with the destinations and selects the storage location containing the data to be transmitted via each transmission circuit as it is scanned. The device operates as an automatic buffer store which connectes between a central computer and a number of remote devices without interruption at either interface. As shown, thirty transmission lines are scanned by a line control 114, as described in Specification 963,959, and as each line is scanned a corresponding control word is transferred to a control word register 116. The control word includes a "general buffer area" in which the address in store 102 which has been allotted to the particular line being scanned, is stored. At each scan a further bit of each message from each active destination device is added to the corresponding storage location so that each message is built up ready for transmission to the central computer as described in Specification 969,314. Messages to be transmitted from the central computer to one of the remote stations are receives serially by bit from the computer on a line 108, are demodulated at 109, converted to parallel by bit serial by character in a shift register and passed to a storage register 111. They are then applied through a terminal address decoder 200 to a terminal address store, and also to a data register 101 during step 31 of the counter 118, at which time a further control word is in the register 116. The output message is compiled in the memory 102 at an address stipulated by the control word. When the message is completed an end of message detector 203 sets a trigger 204. When the line on which transmission is required is scanned, a compare circuit operates to enable AND gates 207, 208 so that either a gate 210 or a gate 214 is opened, so that the address within the store 102 of the data to be transmitted is entered in the control word "general buffer area", or if this is in use, in the "buffer area wait" portion of the control word. When the "general buffer area" is cleared at the completion of a transmission, AND and INVERT logic operates a gate 216 to gate the address stored in the "buffer area wait" section of the control word to the "general buffer area" section so that transmission of the next message can be initiated.

Abstract: 1,072,549. Analogue-to-digital converters. SIEMENS A.G. Sept. 14, 1965 [Sept. 15, 1964], No. 39161/65. Heading G4H. In a pulse-code modulator of the kind in which the input signal is sampled, converted to a pulse-duration signal which is applied to a generator which supplies A.C. of a predeter. mined frequency to a binary counter, the value of which is transferred in parallel to an output circuit, a switching arrangement is provided which interrupts the counting process as soon as the full capacity of the counter is reached. This prevents the counter returning to zero and giving a false low value for a large signal. In the form of Fig. 1 (not shown) the outputs of the counter stages (K1-K4) are connected to an AND gate (U) which responds when all stages are set (i.e. at maximum count) and opens gate (Sp) to prevent any more pulses reaching the counter. The value transmitted is therefore the maximum. In another form the counter is allowed to exceed its capacity but the reversion of the most significant stage to " 0 " causes the outputs from the counter to be disconnected and each output line to be connected to a source of " 1's " so that a maximum value is again transmitted.

Title: Improvements in or relating to the manufacture of shaped sintered bodies of alkaline earth metal carbonates or oxides
IPC: H04J1/16
Filed: 1965-09-14
Abstract: In manufacture of a sinterd body composed of at least one alkaline earth carbonate from the group comprising Bc, Ca, Sr, Ba and Ra, for use in dispenser cathodes, there is formed a thixotropic suspension of the powdered carbonate in a polar liquid and in the absence of electrolytes, the suspension being such that in the compacted state formed at rest, the powder is not completely moistened by the liquid. The suspension is then converted into a pourable slurry by agitation and a solidified body of desired shape is formed from the slurry. This body is dried at a temperature slightly above the boiling point of the polar liquid and sintered at a temperature slightly below the dissociation point of the carbonate, e.g at 600 DEG  to 950 DEG  C. The polar liquid may be water, methanol, ethanol, propanol or acetone. The body may be formed in a mould of ceramic or elastic material and may be removed therefrom either before or after sintering. Alternatively, the slurry may be poured on to a ceramic plate to form a layer from which shaped bodies are punched out and subsequently dried and sintered.  Specific examples and dimensions are given.  The sintered carbonate body may be subsequently decomposed to form the corresponding alkaline earth oxide.

Title: Improvements in or relating to apparatus for cutting sheet glass
IPC: C03B33/10
Filed: 1965-09-15
Abstract: Apparatus for cutting sheet glass comprises a cutting wheel rotatably arranged on a mount attached to a carrier, the wheel being adapted to be pressed against a sheet of glass to be cut, the mount being pivoted on the carrier about an axis vertically normal to the axis of rotation of the wheel and offset to said axis of rotation, whereby in use the plane of the wheel can be automatically aligned with the cutting line. The carrier apparatus is the same as that described in Specification 1,056,639.  At one end of a pivotal arm 6 is attached a mount 10 (Figs. 1 and 2, not shown) comprising an element 20 fixed to a shaft 26 rotatably mounted in ball races in a housing.  The axis A-A of shaft 26 is vertical and is offset from the axis of rotation Y-Y of a cutter wheel 7.  Flexible strips 29 secured to the top of mount 10 and embracing either side of the arm 6 restrict the angular movement of the mount 10.  Thus if the plane of the cutter wheel 7 is initially offset from the line of movement of a glass sheet the pivotal mount automatically allows the wheel to be correctly aligned. In an alternative embodiment the axis of sliding motion E-E of the main carriage is arranged to pass through the centre of the axis of rotation of the cutter wheel, the pivotal axis A-A of the mount 10 being offset from these axes. In a further embodiment the axes E-E and A-A are coincident and both pass through the axis of rotation of the cutter wheel when stationary. However, the wheel 7 is attached to an assembly 81 (Fig. 9, not shown) which comprises a lug 82 engaged in a yoke 83 on the body of the mount 10 by a pin about which the assembly 81 can pivot. Thus in use the axis of rotation of the cutter wheel is offset from the axes E-E and A-A. The above arrangements permit the cutter wheel to follow any changes of direction of the cutting line on the glass sheet.
