Title: Multiple character generator
IPC: H03M11/02
Filed: 1970-08-19
Abstract: 1285288 Cathode-ray tube character display BUNKER RAMO CORP 19 Aug 1970 [8 Oct 1969] 39998/70 Heading H4T An arrangement for decoding special characters (e.g. a character representing a frequently-used word or phrase) and converting each into a string of alphanumeric characters comprises a detector 28 which when one of these characters is recognized sets flip-flop 14 to disable at 18 the normal path for the character signals from keyboard 12 to memory 26 and to enable a counter 36. The first four bits of the composite character passes to matrix 32 together with the count (zero) registered in 36, and this matrix (which may be a diode matrix or other read-only store) generates the first alphanumeric character which passes via gates 40 and 22 to memory. Counter 36 is advanced at each character clock time to step the input to 32, thus producing a sequence of output characters until an 'end-of-sequence' code recognized at 52 resets 14 and 36. The invention is described in relation to the ASCII code and to a system for C.R.T. display of the alphanumeric characters by the use of video signals produced at 66. Fig. 2 (not shown) illustrates a multiplexing arrangement whereby the matrix 32 is shared by three concurrently operative keyboards.

Title: Testing data processing apparatus
IPC: G06F13/00
Filed: 1974-09-17
Abstract: 1452015 Testing a data processing system INTERNATIONAL BUSINESS MACHINES CORP 17 Sept 1974 [8 Oct 1973] 40377/74 Heading G4A [Also in Division H4] A data processing system is tested by transmitting via modems and a transmission line a suitable test micro-program to it from a remotely located central test station, executing the program on the system to generate result data, and transmitting the result data to the central test station for analysis. The central test station and the system under test may be similar and comprise a micro-program controlled processor with a writable program store, an input keyboard, a display, an auxiliary magnetic disc program store, a printer etc. Micro-programs are transmitted to and stored in the system under test and are executed to generate result data. The programs are then deleted from the system under test and the result data is transmitted to the central station where it may be compared with similar data developed by executing the same programs on the central system. The micro-programs in the system under test may be modified from the central station in order to correct faulty operation. The transmissions are controlled by transmit and receive micro-programs resident in both systems which are arranged such that data keyed into and displayed at one, may be displayed at the other. The data is handled in parallel in bytes in the data processing systems and is transmitted serially by bit over the transmission line. Each transmission consists of a number, e.g. 13, of header bytes, the bits in the first twelve of which are different from byte to byte and equal within a byte, the bits in the last byte alternating; a length counter field having a length indicative of the length of the data; an error field containing error detection data; the data field; and two trailer bytes. Synchronization between transmitter and receiver is achieved by causing a signal transition at the end of each byte, inserting an accurately determined delay following the transition, and transmitting the next byte after the delay. The bits are scanned, at the receiver under the control of micro-program loops, and following the scan of the last bit of a byte the scanning frequency is drastically increased. The byte terminating transition and the subsequent delay can thus be measured accurately. At the end of the delay scanning of the next byte resumes at the normal frequency. If the terminating transition is not detected a predetermined time after the scan frequency is increased, the receiver discontinues receipt of the data and selects a resynchronizing routine which, on receipt of the next set of header bytes, resynchronizes the system. On receipt of the data an error field is calculated and compared with the received error field to indicate transmission errors.

Filed: 1970-08-24
Abstract: 1287089 Wrapping tyre bead cores CONTINENTAL GUMMI-WERKE AG 24 Aug 1970 [18 Sept 1969] 40658/70 Heading B7C [Also in Division B8] An apparatus for wrapping a wire core 14, for a pneumatic tyre bead core, in a rubberized cord or fabric strip 13, whose edges overlie the core 14 and are arranged to be adhesively secured to one another around the core 14, comprises annular press members provided on each side of a support ring 1 mounted on a shaft 3 for rotation therewith. The external surface of the ring is adapted axially and radially to receive a wire core 14 thereon and the press members are movable radially outwardly of the support ring relative to the core 14 by means of an inflatable annular bag 8 into respective positions in which they force the edges of the strip 13 against one another after wrapping the strip around the core 14. In the embodiment of Fig. 2, one press member 5 consists of a plurality of segments 7 radially displaceable in the direction of the arrow 6, the segments 7 abutting one another to form a ring in their radially innermost position. Inflation of an annular bag 8 with compressed air through a pipe 9 causes the segments 7 to move radially outwardly and an annular coil spring 10 ensures the return movements of the segments 7 upon deflation of the bag 8. A second press member is formed by an annular bag 11, inflatable via a hose 12, on a hub portion 2 of the ring 1. A frusto-conical deflector 15, which is axially displaceable on the shaft 3, engages the inflated bag 11 and rolls it over the wire core 14 to compress the edges of the strip 13 against the segments 7. In the embodiment of Fig. 4, the press members are formed by annular coil springs 17, 18. The spring 17 surrounds the outer peripheral surface of the segments 7 and radially outward movement of the segments 7 allows an increase in the diameter of the spring 17 so as to wrap one edge of the strip 13 around the wire core 14. Inflation of the bag 8 causes movement of a cone-shaped member 19 in the direction of arrow 20 and consequent radially outward movement of the segments 7. A spring 21 returns the member 19 to its retracted position on deflation of the bag 8. The spring 18 is mounted upon the hub portion 2 of the ring 1, and, upon axial displacement of the deflector 15 with respect to the shaft 3, is rolled up and over the core 14 and over the spring 17 to bring one edge of the strip 13 into securement with the edge carried by the spring 17.

Title: Improvements in or relating to the preparation of tris (organo-amino) boranes
IPC: C07F5/02
Filed: 1961-11-15
Abstract: Tris(organoamino)boranes are made by forming at a temperature below room temperature a mixture of a tertiary amine of the formula R.N(R1)R11, where R, R1 and R11, which may be the same or different, represent hydrocarbon substituents, two of which may be linked together to form a nonaromatic ring system, with boron trichloride or tribromide, there being at least 3 molar proportions of amine for each molar proportion of boron trihalide, and completing the reaction at an elevated temperature.  Preferably the initial mixture is formed at a temperature of 0 to -80 DEG C., the mixture is allowed to warm to room temperature and the reaction completed by heating under reflux.  An excess of tertiary amine is the preferred reaction solvent but non-hydroxylic hydrocarbon solvents may be employed if desired.  Preferred amines are those in which R, R1 and R11 each represent a lower alkyl group of 1 to 6 carbon atoms which is either unsubstituted or carries at least one phenyl substituent, a phenyl group which is either unsubstituted or carries at least one phenyl or lower alkyl substituent, or a naphthyl group.
