Title: Apparatus providing communication in synchronous mode between  any one of a plurality of terminal devices and a multiplex
IPC: H04L5/00
Filed: 1973-11-29
Abstract: 1457285 Data transmission; master and slave systems SIA INTERNATIONAL 29 Nov 1973 55328/73 Heading H4P An arrangement for synchronous connection of a plurality of terminals to a multiplexing channel 2 comprises an interface multiplier unit 1 connecting the channel to a plurality of first modems 8-10, each connected through a data channel to a second modem, e.g. 11 which serves a terminal, e.g. 5. The multiplexing channel has a receive data circuit and each first modem has a "receive data" circuit and a "carrier on" circuit whereby the multiplier unit has a logic means for effecting the product, e.g. AND operation of the "receive data" circuit and "carry on" circuits of the respective first modems. In Fig. 1, multiplier unit 1 is connected through a channel of multiplexer 3 to a computer 4. In use, the multiplier (a) transmits data from the computer to all terminals which decode its particular address, (b) recognizes which terminal is transmitting, one at a time, without decoding addresses and (c) switches, data to the computer together with associated clock signals. In a modification (Fig. 4, not shown) some terminals (e.g. 33, 34) may be connected directly to the interface multiplier, (la), also additional modems (31, 32) with an associated duplex or simplex channel may be connected therebetween.  Details of logical arrangements are given in the Specification. Fig. 7 (also not shown) illustrates a buffer circuit to take up shift between individual clocks.

Title: Semiconductor data storage device
IPC: G11C16/04
Filed: 1973-11-29
Abstract: 1445450 Semiconductor data storage INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1973 [29 Dec 1972] 55360/73 Heading H1K A floating gate data storage FET 10 (Fig. 1) is coupled to conventional word driver 12, bit driver 14, and bit sense amplifier 15; and comprises a semiconductor substrate 16 of, e.g. N-doped Si having opposite conductivity diffused P doped source and drain regions 17, 18 separated by channel region 19. An insulant layer 21 of SiO 2  is formed over the substrate, etched into openings for source and drain diffusion and for the channel, and an oxide layer 24 of thickness to prevent tunnelling with normal I operating voltages is reformed in the channel opening. A gate electrode 25 of semiconductor material devoid of free carriers is deposited on the oxide layer 24 and is encapsulated in insulant 26, e.g. similar to layer 24 so as to float electrically. Contacts 27, 28 are applied to source and drain diffusions 17, 18 and an overlying drive gate electrode 29 is deposited on layer 25. Drain electrode 27 is coupled over 2-piston switch 30 to bit driver 14 and sense amplifier 15 or to earth, while source electrode 28 and substrate 16 are both earthed. Drive gate 29 is connected to word driver 12. Gate 25 may consume excess charge to create conductively a channel between source 17 and drain 18 to represent logic "1"; logic "0" being denoted by its absence. For logic "1" write in, the drain electrode 27 is switched to the bit driver 14 and sense amplifier 15 and the former is driven to produce ave pulse (Fig. 2 not shown) on the drain to backbias region 18, and a + ve pulse is applied to the gate electrode 29 from the word driver 12. Avalanche breakdown between drain region 18 and substrate 16 proximate to region 19 generates high energy electrons beneath the floating gate which pass thereto through layer 24 under influence of the prevailing electric fields and are stored. The accumulated electrons induce a channel between source and drain diffusions 17, 18 and the existence or non- existence of the source denotes the presence or absence of this electron charge. Low level read pulses on drain electrode 27 and drive gate electrode 29 enable detection of stored charge by the appearance of pulses on the sense amplifier 15. Charge is removed from the floating gate 25 to eliminate the induced channel and erase the storage by setting switch 30 to earth and negatively pulsing drive gate 29 from the word driver 12 so as to deplete the floating gate by avalanche breakedown into region 19. Plural short pulses may be used for erasure.

Abstract: 557,840. Treatment of seed. MELVILLE, F. A., (Representative of MELVILLE, J. J.). May 5, 1942, No. 6043. [Class 58] Seed germination and growth, particularly of barley, wheat and oats, are improved by treatment with a medium prepared as follows :-2ozs. of calcium oxalate and 3¢ ozs. of zinc sulphate are mixed with 20 galls, of hot water and distilled. From the seed to be treated, 5 lbs. per cwt. of the seed are suspended in a tray &c. over the distillate which is heated sufficiently to evaporate slowly. The apparatus is enclosed, but the wheat is moistened with ammonia solution and turned three times a day. After a week the decomposing wheat is transferred to a tank which is filled up with the liquid from below the wheat and with hot water. The wheat is squeezed, the whitest liquid removed to a wooden trough, and the process repeated until the water remains clear. To the trough there is added a mixture prepared from 7 oz. common salt, 7 oz. transparent rock salt, 7 oz. carbonate of potash, 2 ozs. menthol, 2 ozs. clove oil, and 33 gallons of warm water. The bulk of the wheat to be treated is then lowered into this medium, allowed to remain for twelve hours, taken out and dried. Winter-treated seed may require two dippings. Premature germination may be checked by dipping in a mixture of 2 ozs. dextrine and 1 oz. alum in 20 galls. of cold water. One pound of spirits of wine may be added, immersion being limited to one hour.

Abstract: 1,164,268. Electron beam apparatus. AIR REDUCTION CO. Inc. 13 Dec., 1966, No. 55797/66. Heading H1D. Electron beam apparatus for treating material 24 comprises an air-tight enclosure 10 divided into chambers 12, 14 and 16 by barriers 18 and 20 with apertures 26 and 28 of the same size and shape as emitting surface 22 (preferably a Pierce type gun with a directly or indirectly heated cathode, Fig. 2 (not shown). A uniform magnetic field provided by ironcored coils 42, 46 or Helmholtz coils (60), (62) and (64) (Fig. 3, not shown) for instance, cause electrons from surface 22 to follow a helical path to the aperture 26 and between apertures 26 and 28, the distances between the apertures and the emitting surface being equal to an integral number of revolutions of the helical path. The apertures are preferably rectangular to promote molecular rather than viscous flow between the pressure graded chambers. The pressure difference on the opposite sides of each barrier may be in the ratio of between 10: 1 to 100: 1. The gun chamber may be evacuated to 0À6 or higher than 0À1 Á Hg. the transition chamber to 17 Á Hg. and the treating chamber to 100 Á Hg. Polepieces 38, 40 and 44 may be a ferromagnetic such as steel, or the barriers (18a) and (20a) (Fig. 3, not shown) may be of watercooled copper. To minimize contamination of chambers 12 and 14, target 24 may not be in alignment with the apertures, a transverse magnetic field effecting curvature of the electron beam after aperture 28. More than one gun 22 may be included with associated apertures and only two or more than three chambers may be provided. Reference is made to melting, annealing, cleaning and vapour-plating.

Title: Transmission system
IPC: F16H47/08
Filed: 1972-12-07
Abstract: 1411586 Variable speed gears USTAV PRO VYZKUM MOTOROVYCH VOZIDEL 7 Dec 1972 56605/72 Heading F2D In a variable ratio gear for automotive vehicles the turbine 3 of an hydraulic torque converter, of which the impeller 2 is driven by the input shaft 1, is connected by a tubular shaft 7 and reduction gearing 6, 22, 8 to a tubular shaft 20 and sun-wheel 9 of an epicyclic train, a second sun-wheel 15 of which is driven by a shaft 16 which is connectible by a clutch 18 either with the input shaft, as shown, or, in a modification, with the turbine 3, the planet carrier 13 of the epicyclic train drives the output shaft 14, and a ring gear 10 may be held by a brake 21 for selecting reverse ratio. Both the reaction member 4 of the converter and a carrier 17 for the pinions 22 are connected to the gear casing by over running clutches 5, 19. For low ratio a clutch 12 is engaged to lock the carrier 13 to the shaft 20, and power is transmitted through the turbine 3 and reduction gearing 6, 22, 8. Engine braking may be effected in this ratio by applying a brake 11. Intermediate ratio is established by releasing the clutch 12 and engaging the clutch 18, when power is transmitted partly through the shaft 16 to the sun-wheel 15 and partly through the turbine 3, reduction gearing 6, 22, 8, and the sun-wheel 9. Engine braking is also available in this ratio if the brake 11 is applied. High ratio is direct, established by engagement of both clutches 12, 18, and reverse is obtained by engagement of the brake 21. In the modification referred to above, in which the clutch 18 connects the shaft 16 with the turbine 3 instead of with the input shaft 1, four forward ratios are provided, low being obtained by engaging the clutch 18 and brake 21, and second, third and fourth corresponding to first, second and third in the three-speed version. In another modification, the clutch 12 is connected to the shaft 20 through an overrunning clutch, and a friction clutch interconnects the planet carrier 13 and the ring gear 10. This arrangement simplifies control by allowing upshifts from first to second speed to be effected without disengagement of the clutch 12, and third speed to be established by engagement of the clutch between the carrier 13 and ring gear 10. In further modification, suitable for front-drive or rear-engined vehicles, the input shaft 1 extends to a clutch 18 inside the gearbox, the output from this clutch and that from the turbine 3 are transferred by gears to coaxial shafts whose axis is parallel to and below that of the shaft 1, and on which are mounted the sunwheels 15, 9, and through which the output shaft 14 passes to a final drive location between the torque converter and the gear-box.

Abstract: 1285777 Protective systems TEXAS INSTRUMENTS Inc 27 Nov 1969 [30 Dec 1968] 58136/69 Heading H2K [Also in Division H3] An overload protective arrangement for a load, e.g. a motor M, comprises an A.C. triggerable semiconductor switching device, e.g. a triac Q, connected across an A.C. supply in circuit with means KW controlling the supply to the load, a thermistor S1 heated by the load and connected to the gate of the switching device, and means connected to the thermistor for initiating conduction of the switching device and thereafter to supply triggering current to maintain conduction of the device and energization of the load until the heating of the thermistor S1 due to overloading reduces the triggering current. The triggering current may be supplied through a resistor R1 and a capacitor C1. The triac Q may be initially rendered conductive by a pulse through a resistor in which case the arrangement resets automatically when the temperature of the motor falls, Fig. 1 (not shown). Alternatively a further P.T.C. thermistor S2 may be used to initiate conduction. This thermister S2 may be disposed in the motor as shown and have a lower transition point than the thermistor S1 so that resetting with re-energization of the motor occurs at a predetermined lower temperature than that at which the supply to the motor is interrupted. In another arrangement this thermistor S2 may be self heating so that disconnection of the supply is necessary to enable resetting, Fig. 3 (not shown). A time delayed reset is obtained in Fig. 4 (not shown), by using the self heating thermistor S2 in conjunction with a P.T.C. thermistor connected across the triac and acting as a heater for an N.T.C. thermistor connected in parallel with the thermistor S2. Fig. 5 (not shown), illustrates an arrangement in which the further thermistor S2 is heated by the triac Q and acts to stabilize the reset temperature.

Abstract: 1455717 Photo-electric measurement of  radiation dosage INTERNATIONAL STANDARD ELECTRIC CORP 19 Dec 1973 [20 Dec 1972] 58732/73 Heading G1A A radiation meter which measures the dose or dose rate of an ionizing radiation is provided with a multi-position switch so that the sensitivity of the meter can be adjusted depending on the ionization energy of the radiation. The switch, which is in addition to any normal range changing switch,  makes the use of conventional calibration curves of energy against output unnecessary. The switch can alter the detector output current, or if the detector produces pulses the switch may operate circuitry to remove some pulses; alternatively the switch may attenuate the current passed to the meter read-out device, or may control the detector amplifier. In one construction, Fig. 2, the switch has a knob 15 recessed into the meter, and the knob is easily removed by release of screw 17 when the meter is to be decontaminated. In Fig. 3, the switch shaft 13 has a slotted end which can be turned with a coin, and the switch contacts, form part of a printed circuit board. If desired, the readout can be on a dial as shown, or a digital display or a printer. The detector may be remote from the meter and be connected by a cable.
