Abstract: 1401265 Calculator; keyboard and display TEXAS INSTRUMENTS Inc 27 June 1972 [19 July 1971] 44626/74 Divided out of 1401204 Headings G4A and G4H A calculator has a keyboard having a plurality of keys arranged in rows and columns, a plurality of output display devices, and a means for generating repetitive sequences of timing signals, each of at least some of said signals being connected to energize simultaneously a respective individual column of keys and a respective individual display device. The calculator is adapted for construction on a metal-insulator-semi-conductor integrated circuit chip and includes a read only program memory, a read/write arranged to provide a number of data registers for storing data serially by digit parallel by bit, and a binary or binary coded decimal serial by digit adder. The display elements may be light emitting diodes, liquid crystal devices, cold cathode discharge elements, fluorescent display elements &c., and as described are multisegment digit displays with coded segment select signals being applied to all the display elements one of which is selected by a timing pulse. The timing pulses and/or the coded segment selecting pulses may be truncated on their leading and trailing edges to prevent spurious displays due to "carry over" of the signals from one digit to the next. The keyboard is scanned by the timing signals, transient signals, e.g. due to keybounce, being overcome by scanning until a significant output is detected and re-sampling 1À5 msecs. later to distinguish a valid key operation. Instruction execution is generally conventional, an instruction address normally being incremented, there being provision for instruction address modification for conditional jumps in the program, or maintaining the same instruction address for "wait" instructions. An exemplary program is given.

Abstract: 924,116. Bearings. AGFA A.G. Dec. 19, 1961 [Dec. 31, 1960], No. 45508/61. Class 12 (1). [Also in Group XVIII] A beam of a balance has a radially and axially centring air bearing. In an embodiment, a torsion spring balance has a column 1 which supports one end of a bearing pin 2 clamped thereto by spring tongues 3. The pin 2 has an integral collar 5a, an extension 6 and an axial bore 7, which is screw-threaded at 8 to receive an air hose. A bush 5b is mounted on the pin 2 which, together with the collar 5a, forms a stationary roller 5; the bush 5b is adjustable to vary the width of a radial gap 9 between the members 5a, 5b. The gap 9 communicates with an annular channel 10 in the bush 5b which is connected to the axial bore 7 by a radial bore 11. The beam 13 is carried by a bush 12 which is mounted on the roller 5 and retained by flanges 14, 15 so as to provide a cylindrical gap 16 and radial gaps 17, 18 leading to discharge recesses 29, 30. A screen disc 26 is attached to a portion 27 of the column 1 by means of a bolt 28 to prevent the escaping air from impinging on the column 1 and so effect the accuracy of the balance. A bracket 19 is attached to the bearing 13 and by a screw 20 to a clamping jaw 21 which holds an end of a torsion-spring 23, the other end of which is attached to a ring 25 of a shaft 24 rotatable by a motor (not shown).

Abstract: 1,047,630. Oil burners. O. GOLDMANN, O. HIMSTEDT, and E. SCHWARZE. Nov. 25, 1963 [Nov. 23, 1962], No. 46509/63. Heading F4T. In a liquid fuel burner comprising a highpressure nozzle 19 injecting fuel into the Venturishaped entrance to a mixing chamber 10, hot waste gas and air are supplied to the intake side of a blower 7 and the mixture of waste gas and air is delivered with a rotating movement to the narrowest portion of the Venturi. The cone angle of the Venturi is larger than the spray cone of the fuel. The mixing chamber 10 is mounted inside a trough 3 and has an outlet 10<SP>1</SP> remote from the Venturi through which the fuel/air/waste gas mixture enters the trough 3. The latter is closed by a screen 4 above which the mixture burns. The waste gases are sucked by the blower through channels 5<SP>11</SP> formed between the trough 3 and the walls of the burner housing 1. Fresh air enters the blower through a pipe 8 having an adjustable throttle 9. The blower is driven by a motor 23 having a hollow drive-shaft provided with radial air intake openings 26. The motor also drives a fuel pump 27. The output of the blower is delivered to a narrowing spiral channel 21, surrounding a shell 15 surrounding the fuel nozzle 19 and having a conical front portion forming with the Venturi an annular slot 16 which can be adjusted by moving the shell 15 axially by means of its threaded connection with an end piece 14 of the mixing chamber 10. Cold air is sucked in through the shell 15 and cools the fuel nozzle. At starting the motor and an air heating resistance in the channel 21 are switched on. A solenoid fuel valve 28<SP>1</SP> is closed so that air only is delivered to the mixing chamber. When the air reaches a temperature of 250 C. a thermostat in the channel 21 actuates a relay to switch off the heating resistance and to open the solenoid valve 28<SP>1</SP>. The mixture of fuel and air is ignited by an electric device 31. In an alternative method of starting, the fuel air mixture is ignited for a short heating up period in the mixing chamber. In a modification, Fig. 6 (not shown), the blower has a double-faced fan wheel discharging into a common outlet, a fresh air intake being provided on the drive side of the wheel and a waste gas intake on the other side of the wheel.

The undesirable interference of that draught with the working of the cleaning device is thus reduced or prevented. Another embodiment (Fig 10) has an additional rotary beater and separator 90 which serves not only to assist the transfer of straw but also to provide additional separation through the concave 93. All the separated grain is transferred to the cleaning device 16 via a grain pan 97 and a transfer pan 15. An auxiliary member 100 assists the grain pan 97 in forming a shield between the rotors 8, 9 and the additional rotary beater on the one hand and the cleaning device 16 on the other. This shield ensures that the draught from the rotary devices is not directed towards the sieves 64, 66 and thus will riot interfere with the action of the fan 17 in separating the chaff from the grain. The grain pan 97, the grain transfer pan 15 and the additinal protective screen 100 are attached to the upper shoe for vibratory purposes. Parts 99 and 101 are flexible seals.  Additional blowing means may be placed beneath the protective screens 97, 100 to direct a draught to carry away chaff from the combine through an outlet at the forward end.
