Filed: 1938-09-17
Abstract: 519,310. Cracking and coking oils. NAAMLOOZE VENNOOTSCHAP NIEUWE OCTROOI MAATSCHAPPIJ. Sept. 17, 1938, No. 27163. Convention date, Sept. 21, 1937. [Class 32] Coke of low volatile content, e.g.; 1 per cent. suitable for use as electrode coke is obtained by distilling crude stock and separating the products into vapours and liquids, cracking the vapours with the aid of hot carrier gases, cooling the cracked products to condense heavy fractions, and reducing the heavy liquid fractions with or without the heavy fraction from the initial distillation to coke while passing hot carrier gas therethrough. Crude stock fed through line 1 is pumped by a pump 2 through a heater 5 into a flash drum 6. The vapours formed are passed through line 7 to a superheater 8 and then mixed with hot carrier gas and passed into a cracking chamber 11. The cracked products pass to a separator 13 from which the vapours pass to a fractionating tower 35 while liquids are passed through lines 14, 16 to coking drums 17a, 17b, to which the heavy liquids collected in drum 6 are also fed. The vapours in the tower 35 are fractionated into vapours which are removed from the top of the tower through line 40 and condensed and collected in coolers 41, 49, receivers 43, 50 and absorber 56. Fixed gases are removed through line 19, 22 and after heating to high temperature in-coils in the furnace 8 are passed through lines 28, 30, 29, 31 into the coking chambers. Reflux collected at bottom of tower 35 together with topped crude if fed to this tower through line 36 are recycled to coil 5. Specification 385,610 is referred to.

Title: Lead making apparatus
IPC: H01R43/052
Filed: 1965-06-28
Abstract: 1,041,357. Making electrical connections; Jointing by stamping; shearing. AMP INCORPORATED. June 28, 1965 [July 30, 1964], No. 27236/65. Headings B3A, B3Q and B3W. In apparatus for making electrical leads a wire 46 is fed through an aperture 16 in a plunger 14 so that it overlies the ferrule 62 of a connector, which has been advanced over an anvil 20 by the left-hand finger 38. A ram 1 is driven to cause a die 5 to crimp the ferrule to the wire 46 and simultaneously a shear plate 2 descends to shear the connector from the lefthand connector strip 59. The plunger 14 enters a space between the anvil 20 and a plate 21 thereby preventing shearing of wire 46 (Fig. 2, not shown). The ram 1 is returned, the righthand finger 38 advances the right-hand connector strip 59 and the crimped connector is lifted by the die 5. The wire 46 is then advanced by a predetermined length. The advance of the feed finger moves a plate 24 into the space between the anvil 20 and plate 21 (Fig. 3, not shown) and a deflector plate 29 pushes the wire clear of the shear plate 2. The ram performs a second working stroke, the shear face 10 of a plate 9 shearing the connector from the strip 59, the die 5 crimping the ferrule 62 and, since the plunger 14 abuts the plate 24, a frame 12 moves relative to the plunger and the wire 46 is sheared between an edge 13 of the frame 12 and the edge of the aperture 16.

Title: Improvements in data-processing apparatus
IPC: G06F3/06
Filed: 1959-08-11
Abstract: 933,474. Electronic computers. MINNEAPOLIS-HONEYWELL REGULATOR CO. Aug. 11, 1959 [Aug. 11, 1958], No. 27431/59. Class 106 (1). Idle time in a computer is reduced by the use of a cyclically-operating device scanning a number of lines on each of which signals indicating readiness for a data-manipulation operation may exist, and control means responsive to a signal so selected to initiate the required operation. In the computer shown schematically, two such scanning devices are used, the first is a traffic control circuit 10 scanning the buffers of a number of peripheral; units PD1-PD5 to detect which of these units (e.g. magnetic tapes, printers, punched card readers) require data transfer. Circuit 10 has eleven stages, of which TC1 is active during operation of a programme step. On completion of this, the traffic control will step to the first TC stage receiving a demand signal over DL1-DL10; (as shown each peripheral unit has a separate input and output buffer with its own demand line, although printers and card readers, for example, will only have one buffer) and this demand signal will be transmitted to the address register 16 of a control memory 14 where the addresses in main memory 18 from or to which the data to be transferred are recorded for each buffer. The appropriate main memory address is thus transferred to register 20, and the data word can now be transferred over line 60; the address sent to 20 is incremented by one and returned to 14. When this is done, circuit 10 steps to the next TC stage calling for data transfer, and so on until TC1 is reached, when the next programme step is initiated. The second scanning arrangement 12 acts in similar manner to effect time-sharing of the computer between a number of programmes to be performed " in parallel." The programmes, if in course of execution, cause lines SRD to be energized, and unit 12 scans to select a programme step from each in rotation. The addresses in 18 of the next steps of each programme are also stored in 14 and selected in turn as before, incremented and returned to 14, and sent to the control unit 22 where they call for their data from 18 as required, and return all results to 18 from accumulators so that unit 22 is then free for use by the next programme. The Specification describes and illustrates logical circuits for units 10 and 12 and for deriving the timing signals TTC and TSR used for stepping the scanning circuits. An error signal resulting from an error in one particular programme acts to by-pass unit 12 from this programme so that others may continue without a total stop, if desired.

Filed: 1961-07-28
Abstract: 988,681. Automatic attitude control; optical apparatus: mirror mounts. BARNES ENGINEERING CO. July 28, 1961 [Aug. 26,1960], No. 27482/61. Headings G2J and G3R. [Also in Divisions H3 and H4] An oscillatory scanning device comprises an oscillating member 1 Fig. 1 carrying a mirror 2 or a photo-electric detector (Fig. 2, not shown), torsion bars 3,4 clamped at 7, 8 and a circuit incorporating an armature 9, a drive coil 10 and a sensing coil 11. Movement of member 1 is inhibited in planes perpendicular its plane of oscillation. The invention is described as applied to a horizon sensor on a satellite utilized to correct the attitude thereof around pitch and roll axes. Radiation enters a window 17, Fig. 5, strikes a mirror 18 capable of slow rotation by means of a rack and pinion, the reflected radiation from oscillating mirror 2 passing to an infra-red photoelectric cell 15 which is located on a lens 15 beyond the centre of curvature of the face of the lens. Three of the apparatusses according to Fig. 5 are arranged as shown in Fig. 3 and the circuits of the corresponding detector outputs are as illustrated in Fig. 6; each differential amplifier 23 produces an output when there is a phase difference between the square wave from circuit 22 and a reference square wave derived from the circuit associated with the oscillation of the corresponding scanning device Fig. 4 (not shown). The output of unit 23 is fed to a motor 24 which drives a corresponding potentiometer 26 and also drives the corresponding pinion 20 Fig. 5. If the satellite rolls from level attitude the outputs of detectors A and B change, corresponding mirrors 18 are turned to keep the scans centred on the horizon, and a signal from differential amplifier 27 affords a signal to servo mechanisms to restore the satellite to level flight. If the satellite moves about the pitch axis a control signal ensues from circuit 28 to restore level flight. If, in level flight, the altitude of the satellite changes, all three scans cease to be centred on the horizon, the absolute values of the outputs from potentiometers 26A and 26C change, and the output from summing circuit 29 represents altitude. Specification 988,682 is referred to.
