Patent GB-1167337-A (GB)
Title: Improvements in or relating to Nuclear Magnetic Resonance
Inventor: HIGHAM PETER
IPC: G01R33/36
Filed: 1966-08-18
Abstract: 1,167,337. N.M.R. spectrometers. PERKIN-ELMER Ltd. Nov. 10, 1967 [Aug. 18, 1966], No.36960/66. Heading G1N. In an N.M.R. spectrometer having a locking channel and a measuring channel, interference between signals excited in the locking sample 4 and measuring sample 7 is minimized by modulating the field of the polarizing magnet at an audio frequency so that resonance takes place at sideband frequencies whereby the interfering signals are not at irradiation power levels but at nuclear resonance power levels. Thus the frequency of the r.f. applied to the measuring sample can be swept through the resonance frequency of the locking sample without the spectrometer going out of lock. The sidebands chosen may be both upper sidebands, both lower sidebands, or one upper and one lower sideband and one or both may be of a higher order than the first. The direction of frequency sweep may be upwards or downwards. As shown in Fig. 1, a locking sample 4 and a measuring sample 7 are placed in a common magnetic field modulated by coil 15 energized from an audio frequency generator 14. The locking sample is irradiated with r.f. from a source 8 and the dispersion mode of the resonance signal is detected in phase detector 11 and used to control the current in a field locking coil 16. The absorption mode of the resonance signal picked up from sample 7 is detected in phase detector 13 and recorded by recorder 17. An oscillator 18 causes the frequency sweep of source 9 to be synchronized with the recorder chart drive. Source 9 may be a sideband generator receiving inputs from oscillators 18 and 8. A potentiometer (not shown) may be provided for adjusting the modulation index.

Patent GB-374059-A (GB)
Abstract: 374,059. Anti - aircraft gunnery. VICKERS-ARMSTRONGS, Ltd. and WATSON, J. P., Vickers House, Broadway, Westminster. Dec. 1, 1930, No. 36194. [Class 92 (ii).] Relates to anti-aircraft fire-control apparatus of the kind comprising a controlling or directorsight the movements of which in elevation and training in following the target are transmitted to a calculator from which the firing data are obtained. According to the invention, in order to adapt the apparatus for guns mounted on rolling platforms, movements derived from the calculator are applied to the controlling sight to compensate in elevation for " sight-roll " in the vertical plane of sight, and in training for "sight trunnion-roll" " in a vertical plane at right-angles to the said plane of sight. The operators at the controlling sight are thereby relieved of the necessity to compensate for roll. The invention is shown applied to the apparatus described in Specification 374,058. The elevation given by the shaft C and generated by the calculator receives a correction for " inclined trunnions " by way of a shaft a<6> and differential gear N, the correction for " sight-roll " by way of shaft a<3> and differential gear N<2> and the correction for " own speed by way of shaft N<4> and differential gear N<5>. The resultant elevation is transmitted to a receiving motor N<7> which conveys it to the controlling sight through a differential gear N<9>. Similarly the training angle given by the shaft D has corrections for " inclined trunnions," " own speed," and yaw applied by differential gears O, O<3>, 05, respectively, the resultant angle being transmitted to a receiving motor 07 which conveys it to the controlling sight through a differential gear O<9>. Tuning handles N<10>, O<10> are operated if the target changes its course or speed. The vertical and lateral deflection handles c, d, instead of being situated at the calculator, may be arranged at the controlling sight station and connected to receivers at the calculator. The comparison pointers X, Y described in Specification 374,058 may then be dispensed with as the target becomes the equivalent point of reference.

Title: Semiconductor devices
IPC: H01L21/00
Filed: 1960-11-03
Abstract: 940,681. Semi-conductor devices. WESTING- HOUSE ELECTRIC CORPORATION. Nov. 3, 1960 [Nov. 10, 1959], No. 37808/60. Heading H1K. In a semi-conductor device with a P+N+NP or N+P+PN zone configuration the P+ and N+ zones have an uncompensated activator concentration of at least 10<SP>19</SP> atoms/cc. and form a tunnel junction. The device exhibits a negative registance between electrodes provided on the outer zones which is controllable through a further electrode attached to the inner N+ or P+ zone. A typical device is produced by heating a wafer of 200 ohm. cm. P-type silicon to 1200 C. in a diffusion furnace containing gallium vapour to produce a P+ surface zone 1 mil. thick containing 10<SP>19</SP> atoms/c.c. of gallium which is then removed except from one face of the wafer. Phosphorus is then diffused into the central part of said one face to form an N-type region less than a mil. thick by heating the wafer to 1250 C. in phosphorus vapour. A pellet 18 (Fig. 5) consisting of 99.5 % by weight gold and 5% atimony is alloyed at 750 C. to the opposite face of the wafer, an antimony-gold contact attached to the N-type region and an annular aluminium-antimony contact attached to the gallium doped layer to complete the device. In an alternative method the N region is made by alloying a pellet of 99.5% gold and 5% arsenic to the P + zone by heating to 650-750 C. in vacuum, argon or helium. Removal of unwanted parts of the P+ region may be avoided by suitable oxide masking of the wafer before the gallium diffusion step. Devices using germanium, silicon carbide, and A III  B V  compounds such as gallium arsenide and indium antimonide are also envisaged.

Filed: 1930-12-17
Abstract: 368,426. Removing sulphur from gases. PREMIX GAS PLANTS, Ltd. and DOCKING, A., 10, Victoria Street, London. Dec. 17, 1930, No. 38106. Addition to 329,973, [Class 55 (ii), Gas manufacture &c.]. Class 55 (ii).] The method of removing sulphur from producer gas according to the parent Specification is modified by providing thermostatically controlled means for regulating the temperature to which the producer gas is raised prior to its entry into the purifier. The producer gas is heated in a heater 2 by gas from a source 4, a diaphragm valve 5 controlling the flow of heating gas. The valve 5 is included in a byepass 7, the upper end of which is in communication with a space on one side of a valve inside the thermostat 8. A byepass 9 allows a little gas to leak past the thermostat valve to the heater. If the temperature inside the purifier rises above the predetermined extent, the thermostat valve closes the gas leak through pipe 9. This results in an increased pressure.in pipe 7 which partly closes the diaphragm valve 5 and reduces the volume of gas to the heater.

A remotely controlled valve for automatic irrigation systems which opens after the receipt of a predetermined number of hydraulic impulses applied to the inlet 38 comprises a smaller and a larger diaphragm 5, 4 subject to the inlet pressure and applying a differential thrust against the loading of a spring 21 on a rod 6 which is connected by a pin and slot 16, 14 to a double closure member 15, 15a to maintain the latter in the position shown. A roller 29 on one arm of a spring-biased pivoted bell crank lever 30 is engaged in a groove 28 of the rod having sloping ends. Diametrically opposite the groove is a slot 25 in which is engaged, with a clearance 27 of an end abutment 26, a disc 22 rigid with a ratchet wheel 35. A spring-loaded pawl 33 and a claw 36 preventing reverse rotation engage the ratchet teeth. Negative pressure pulses applied to the inlet cause the rod 6 to move to the right to move the ratchet around one tooth for each pulse due to the pivoting movement of lever 30 caused by the roller 29 riding up the inclined end of the groove. After the predetermined number of pulses have been received a recess 23 in the disc 22 is placed opposite the rod abutment 26 so that the rod may move sufficiently to the right to open the closure. The mechanism is reset and the valve closed by a substantial decrease in pressure and a subsequent restoration of working pressure.

Abstract: 1364134 Controlling thyristors H MANS 1 Dec 1972 [18 Aug 1972] 38531/72 Heading H2F [Also in Division G3] The energization of an A.C. load such as a lamp or heater is controlled by a circuit including a programmable unijunction transistor whose stand-off ratio varies according to a sensed condition. As shown in Fig. 1, a load is connected in series with an A.C. source and a rectifier bridge D1-D4 across the D.C. terminals of which there is connected a thyristor triggered by the output of a PUT. The stand-off ratio of the PUT is determined by a preset resistor R5 and a resistive element R4 which may be a photo-cell or thermistor according as the load is a lamp or heater. The ratio thus varies with sensed light intensity or temperature, thereby controlling the firing angle of the thyristor and the power supplied to the load. The anode voltage of the PUT is regulated by a Zener diode D5 and increases as capacitor C1 is charged at a rate determined by the setting of potentiometer R2 and resistor R3. Sensitivity may be increased by connecting a transistor between the elements R4, R5 and the gate of the PUT, Fig. 2 (not shown). The thyristor may be replaced by a triac or antiparallel SCR pair connected across the A.C. terminals of the bridge D1-D4 and triggered from the PUT output through a transformer, Figs. 3, 4 (not shown).

Abstract: 958,981. Skittle alleys. BOWL-MOR CO. Inc. Oct. 30, 1961, No. 38700/61. Heading A6D. Means for lowering a bowling pin-setting carriage to one of two positions comprises a crank arm with a second crank arm pivoted at the outer end of the first crank arm and having a chain connected between said second crank arm and a sprocket, the said second crank arm being movable to one of two positions in relation to the first crank arm. In the embodiment described a pin-setting carriage E, Fig. 1, is movable to a position I to place pins on the alley floor or to a position J when it is required to retrieve or respot pins. The carriage is lifted and lowered by racks 4, 6 and 8, Fig. 8, via toothed wheels 12, 14 and 18 driven by a chain sprocket 42. The other end of chain 48 is connected to a ring, Figs. 5 and 6, on a crank arm 108 pivoted at 106 on a main crank arm 70. When the main crank arm 70 is moved through 180 degrees from the position shown in Fig. 1, the crank arm 108 may be locked to the main crank arm 70 by a spring- loaded bar 88, Fig. 5, when it is desired to lower the carriage to position J, or the crank arm 108 may be released from the locking bar 88, Fig. 6, when it is desired to lower the carriage to position I. In this case, bar 88 is unlatched by a solenoid-controlled bar 126 which intercepts a roller 120, mounted on the end of bar 88, during angular movement of the main crank arm 70.

A distributer for fluid-operated braking apparatus comprising a quick service valve formed by a valve member and a biased seat member, a main distributer pile arranged to move the valve member, latching means arranged to constrain the seat member, the arrangement permitting the latch means to disengage and allow the seat member to follow up and close the quick service valve upon a degree of brake application obtaining, is characterized in that the latch means and seat member interengage in at least two positions of the said distributer pile. In the embodiment shown, a main pile comprises a stem 24 carrying a main diaphragm 14, subject to brake pipe pressure (BP) and control reservoir pressure (CR) at its upper and lower surfaces respectively, and a diaphragm 20, subject to brake cylinder pressure (BC) and atmosphere (At) at its respective upper and lower surfaces. The stem carries a quick service valve member 18 engageable by a reciprocably-mounted, spring-biased, seat sleeve member 17 having shoulders or steps 15, 16 engageable by the nose 12 of a pivoted bellcrank latching means 9 which is controlled by the stem 8 of diaphragm 4 subject to brake cylinder (BC) and atmospheric pressures. Said diaphragm 4 additionally controls a ball valve 1 in a connection between the control reservoir and brake pipe, said connection also including a choke 2 and a restricter valve 5 mounted on the main diaphragm. A small capacity by-pass choke 6 provides stability of the distributer in the event of minor brake fluctuations. On brake application, the pile moves upwards from the full release position shown and the quick service valve member 18 unseats to vent the brake pipe to atmosphere until the brake cylinder pressure builds up on diaphragm 4 to pivot the latch 9 and release the seat member 17. If on brake release, the brake pipe pressure is built up slowly and the pile is not in the full release position when the control charging valve 1 has opened, it is essential, if re-application of the brake is to be made, to ensure that either valve 5 is closed or the latch is re-engaged in order to prevent flow back from the control reservoir to the brake pipe and to retain the quick service action. Step 15 corresponds to this partial release position, said step being engaged by the latch on brake release prior to the valve 5 opening thereby reducing the range of movement of the pile when the valve 5 is open and quick service is not available.
