IPC: G01D15/16
Filed: 1968-11-19
Abstract: 1,244,996. Pens for recording instruments. P. GUARDIGLI. 19 Nov., 1968 [20 Nov., 1967], No. 54894/68. Heading B6P. [Also in Division G1] Dot printing apparatus for a multi-curve recorder, with a continuous paper chart F comprises a carriage 2, an inking wheel 7 (with ink pads 8 of several colours), levers 4, 5, 6 driving the carriage 2 along a bar 3 between stamping positions (corresponding to the values of variables being recorded) and an inking position and a movable frame 16 rocking the carriage on the bar 3 to effect stamping and inking operations, the position of the frame 16 being controlled by a cam 33 on a shaft 30 and an auxiliary motor 32 driving the shaft 30 and wheel 7 so that the shaft 30 makes a number of complete revolutions for each revolution of the wheel 7 to select the colours in succession. In operation, a servomotor in a measuring circuit determines the position of the carriage 2 along the bar 3 in accordance with the value of the variable selected by switch 39, drive being transmitted from the servomotor shaft 25 through the levers 4, 5 and a pin 18. A recess 33<SP>111</SP> allows a spring-urged lever 11 following the cam 33 to rock in direction A and rock a stamping frame 9 and, through a fork 19, the frame 16 carrying a print wheel 22 so that a coloured dot is stamped on the chart F. Next in the revolution of the shaft 30 another cam 34 closes contacts 35, 36 to apply an arbitrary voltage to the measuring circuit for the servomotor to drive the carriage 2 to the inking position. Then a recess 33<SP>11</SP> allows the lever 11 to rock in direction A again to ink a printing point of the wheel 22, next a projection 33<SP>1</SP> rocks the lever 11 in direction B and due to detents 23, 24 acting on a gear 17 a gear on the spindle 20 of wheel 22 rolls on gear 17 so that on rocking back a new point will be in stamping position. The cam 34 opens the contacts 35, 36 to remove the arbitrary voltage and the switch 39 applies the next variable to the measuring circuit and its value will determine the position of the carriage 2 by the time the recess 33<SP>111</SP> causes the next stamping operation. Each ink pad 8 turns slightly about its own axis whilst it is inking a point.

Abstract: 1,159,442. Separating hydrocarbons. UNIVERSAL OIL PRODUCTS CO. 12 Dec.. 1966, No. 55477/66. Heading B1L. [Also in Division C5] A mixed hydrocarbon charge stream is separated into its components by a process comprising contacting the charge stream with a solid sorbent capable of sorbing at least one component, withdrawing a raffinate stream comprising the non-sorbed components from the sorption chamber, desorbing the selectively sorbed component by contacting the sorbent with a desorbent stream which is separable by distillation from the selectively sorbed component, withdrawing the resulting sorbate stream comprising desorbent and selectively sorbed components, and fractionally distilling the sorbate into two fractions one of which is recovered as product, characterised in that the raffinate stream is fractionally distilled into higher and lower boiling fractions, and one of these and at least a portion of the second sorbate fraction are conbined and returned to the sorption chamber as the desorbent stream. The desorbent stream may comprise either the lower boiling raffinate fraction and the lower boiling sorbate fraction or the higher boiling raffinate fraction and the higher boiling sorbate fraction. The charge stream may comprise a normal aliphatic hydrocarbon, particularly a paraffin, as the selectively sorbed component and at least one branched-chain aliphatic hydrocarbon or cyclic hydrocarbon as relatively less sorbed component. The sorbent is preferably a molecular sieve but other sorbents such as activated carbon, activated alumina, silica gel, absorbent cotton, glass wool, clays, Fuller's earth, bone char and metal oxides may be used.

Title: Time sharing recorder drive circuit
Inventor: RHYNE THEODORE LAUER
IPC: G01S1/30
Filed: 1969-11-14
Abstract: 1,235,425. Radio navigation. NORTHROP CORP. 14 Nov., 1969 [4 March, 1969], No. 55947/69. Heading H4D. A recorder drive circuit comprises two AND gates each having a series of pulses of a width indicative of a navigational line of position fed to one input thereof, switch means for alternately gating each AND gate on, means combining the two AND gate outputs and a device for connecting a power supply to the drive coil of a recorder in accordance with the pulse output from the open AND gate, the write arm of the recorder being deflected in accordance with the average current in the drive coil. In a long range navigation system three pairs of transmitting stations transmit pulses of, e.g. 10KH R.F., each pair transmitting simultaneously. The pulses are received by an antenna (17), (Fig. 1, not shown), and amplified in R.F. amplifier (19). These pulses are then detected in detector 20 whose three outputs D, E, F are pulses at the transmitter p.r.f. (a few seconds) and of width indicative of the phase difference between the signals from the pairs of stations. Two outputs, D, F are supplied to AND gates 33, 37 respectively. The AND gates are opened alternately by pulses from bi-stable 41 driven by synch. generator 40. Gate 37 is driven from the complementary output of that which drives gate 33. The outputs of gates 33, 37 are combined in OR gate 51, the output of which thus alternates between pulses of width equal to those on lines 27 and 29. The OR gate output is used to control the current flow through a transistor 26 which is loaded by the drive coil 28a of the recorder. The inertia of the recorder prevents the pen arm 31 from following the pulsed current flow and the pen is therefore deflected by an amount proportional to the average current. When the arm is deflected the synchronizing generator 40 causes the pen to mark a dot on chart 38. The deflection of the arm and the position of the dot thus indicate the phase difference. Since the average current will be different for the two pulse sequences, two traces are produced on the chart 38. An identical arrangement is used to produce records indicative of the signals on lines 28 and 29 on a separate chart. The common plot of the output D provides a time correlating reference.
