Title: Display apparatus for displaying representations of digitally coded characters
IPC: G06F3/0489
Filed: 1965-10-11
Abstract: 1,056,779. Display devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 11, 1965 [Nov. 2, 1964], No. 43008/65. Heading G4H. Characters to be displayed are presented cyclically and sequentially to display means from storage means, the kind of display being modifiable by means fed by a counter. Characters to be displayed and control characters are stored in a recirculating store and passed in turn via a holding register to a decoder which energizes one output wire per character. The display character wires go to a matrix to produce a 120-bit code for each character which is serialised to control a cathode-ray tube display. Vertical and horizontal sync control characters control the C.R.T. deflection circuits. A counter with a capacity equal to the number of characters possible on the screen at a time is incremented by one each character time and produces an output at a characteristic count. This output causes the brightening of the word reached on the screen, the end of the word being indicated by detection of an S (space) control character. Marker and line manual keys are provided to feed extra pulses to the counter to advance the brightened position by one word or line respectively, every fourth frame for as long as the respective key is held down. If a word thus brightened is to be kept bright despite feeding of extra pulses to the counter to brighten later words, a brighten manual key is pressed to alter the relevant S control character in the recirculating store into a B (brighten) control character which will produce the brightening when recognised by the decoder.

Title: Methods of testing
IPC: G01N23/04
Filed: 1969-08-29
Abstract: 1,237,809. X-ray examination of articles. INTERNATIONAL BUSINESS MACHINES CORP. Aug.29, 1969 [Sept. 13, 1968], No. 43106/69. Heading G1M. [Also in Division H5] A method of examining during manufacture an article such as a laminated printed circuit comprises positioning an X-ray sensitive film 9, Fig. 1, between an X-ray opaque brass template 3 and a steel base 1 by means of locating pins 2, and briefly exposing the film to X-rays 10 through registration holes in the masking plate 3. This is intended to provide registration marks on the film. The film remains unmoved on the base 1 but is then covered by a glass plate instead of the brass plate 3, Fig. 2, and is also covered by exactly registered or positioned but as far unlaminated circuit panels 7 to be inspected for spacing and location of detail features which are then subjected to X-rays 14. The photographed image of the panels 7 is unaffected by the first masked exposure which provided registration marks only, and the film is now developed. The circuit panels are now laminated together and a new film mounted alone under brass plate 3 and given a first or registration marking exposure. The plate 3 is then replaced by the now laminated together panels 8 and the film exposed to X-rays 15, Fig. 3 and then removed. The two films are developed into transparencies and then superimposed in registration on a known light table, Figs. 4-8 (not shown) and examined under a magnifying glass to see if the details of the laminated together or formed circuit laminations as shown on the second transparency are correctly spaced one to another as compared with the originally registered or exactly positioned but unformed laminations shown on the first transparency. In a modification, Fig. 9, the plate 3a is a "picture frame" only bordering the article but permitting X-ray photography of the article and provision of the registration marks to be accomplished in a single step.

Title: Slump rate test of mixed concrete
IPC: G01N11/10
Filed: 1973-09-14
Abstract: 1424911 Testing concrete J A FARGEN 3 Sept 1974 [14 Sept 1973] 43274/73 Heading C1S Apparatus for testing the slump rate of concrete comprises a pair of levers 1, 2 pivoted together at 4 a linear actuator 5 linking the levers at one end, and plates 3 mounted on the levers at the other end. The linear actuator is preferably a double acting preumatic ram 5 supplied with compressed air via a regulator 19 and a spool valve 8. Spool valve 8 has a body connected to lever 2 and a spool connected to lever 1 by members 9 and 10, a pin on member 10 sliding in a slot in member 9. In use, plates 3 are immersed in the concrete and the pressure of air supplied to the left side of the piston of ram 5 is increased until the plates move towards each other. When the ram 5 is fully extended, members 9 and 10 cause the spool of valve 8 to shift, such that the compressed air is switched from the left to the right side of the piston to retract the ram. Shifting of the spool also causes the left side of the piston to be vented through a device 16 which produces a signal, and when this signal is produced the pressure gauge 18 is read as a measure of the slump rate. When the ram is fully retracted, the spool of valve 8 is moved back to its original position. The compressed air may be supplied by a vehicle braking system.

Filed: 1964-10-23
Abstract: 1,079,950. Transistor distributed amplifiers. COMPAGNIE GENERALE D'ELECTRICITE. Oct. 23, 1964 [Oct. 25, 1963], No. 43419/64. Heading H3T. [Also in Division H1] A distributed transistor amplifier uses an elongated base region as one conductor of the input and output lines. In the lumped constant embodiment shown in Fig. 2a a number of transistors are formed on an intrinsic silicon base member by diffusing, into the member, collector regions C 1 , C 2 , C 3 , a common base region B and separate emitter regions E 1 , E 2 , E 3 . The base region forms a common conductor for an input line comprising inductors L 1  and an output line comprising conductors L 2 . The emitters are of increasing area and thus of lower resistance and this compensates for the decreasing resistance which would otherwise occur because of the decreasing bias current along the line. Fig. 3a shows a distributed constant form of the amplifier using a single elongated transistor with conductors extending along the emitter and collector regions C, E to form with base B the lines, the dimensions of the conductors being chosen to provide the required inductance per unit length. The collector line conductor T2, Fig. 5c (not shown), is formed by diffusing phosphorous in a strip along the intrinsic silicon base member beneath the collector and the emitter line is formed conductor T1 by depositing gold or antimony along the emitter region. The emitter increases in width along the line.

IPC: H04N9/29
Filed: 1966-09-30
Abstract: 1,187,588. Degaussing cathode-ray tube apparatus. FERGUSON RADIO CORP. 20 Sept., 1967 [30 Sept., 1966], No. 43888/66. Heading H4T. Degaussing of a cathode-ray tube 19, particularly in a colour television receiver operating with either of two standards selected by a switch 13, is effected by supplying the A.C. mains input to degaussing coils 18a, 18b via one of two thermistors 14, 15 and a voltage dependent resistor 17. Thus on switching on initially by means of mains switch 12, A.C. flows in the circuit via thermistor 14 or 15 depending on the setting of switch 13 and the initially high current flow through the coils 18a, 18b decays rapidly to a negligible value to effect the degaussing as the resistance of 14, or 15 and of 17 increases. When during normal operation it is desired to change the standards, the operation of switch 13 places a cold thermistor 14 or 15 in circuit and a further degaussing operation is effected which removes any magnetism which energization of the solenoids 20a, 20b ... 22b involved in the standard changing operation induces in the tube 19. The arrangement may be modified by providing a change-over switch between the thermistors 14, 15 and the contacts 13a, 13b of switch 13 to allow a new degaussing cycle to be effected i.e. by switching in a " cold " thermistor without operation of the standard switch 13 or the mains switch 12, e.g. if electrical apparatus is used in the vicinity of the receiver or if the position of the latter has been altered while in operation (Fig. 2, not shown).

Abstract: 1,236,115. Casting processes. FORD MOTOR CO. Ltd. 10 Sept., 1969 [13 Sept., 1968], No. 44739/69. Heading B3F. The grain structure of a casting is controlled by rotation of the casting during solidification; columnar grains are formed by rotating the casting at a steady rate such that convective flow in the casting is inhibited, and equiaxed grains are produced by applying an angular acceleration to the casting, the rate of angular acceleration being sufficient to inhibit the formation of a columnar structure. A turbine wheel is formed by pouring molten metal into a mould rotating at a steady speed of 60 r.p.m., after a given period of time switching off the rotationimparting motor until rotation of the mould ceases, and then energizing the motor again, the on-off sequence being repeated until solidification is complete. The outer zone of the wheel had a columnar structure and the inner zone an equiaxed structure, the boundary between the two zones corresponding to the point at which the motor was first switched off. The mould was preheated to 1900‹ F. and the metal poured at 2950‹ F.
