Patent GB-605041-A (GB)
Title: Improvements in and relating to devices for testing the deviation of instruments
IPC: G01C25/00
Filed: 1945-12-12
Abstract: 605,041. Indicating-apparatus. SVENSKA AEROPLAN AKTIEBOLAGET, WILKENSON, E. A., and FAXEN, P. T. Dec. 12, 1945, No. 33702. [Class 106 (iv)] A device for testing the deviation of an instrument or serving as control means for devices controlled by an instrument is described with reference to a gyroscope. An arm 9 oscillates with a Cardan ring 3 and carries a V-shaped member 10. While its resilience holds it in the V, a second arm 12 moves with the arm 9. When a test is to be made, an electromagnet 18 swings an arc 14 toward a stationary arc 13 and clamps a cross-piece 15, fixed to the arm 12, therebetween. Thus, the arm 12 is restrained, the arm 9 is freed therefrom to continue to oscillate with the Cardan ring and the arm 12 moves into the path of a projection 20 on a testing arm 19. A servomotor, not shown, is energized at the same time as the electromagnet 18 and swings the arm 19 until stopped by the arm 12. A friction coupling may be provided to allow the servomotor to continue or the current thereto may be cut off when the arm stops. To this end, the projection 20 when it strikes the arm 12 turns a mutilated pinion 26 to mesh with a gear-wheel 27 driven by a pinion 28 rolling round a fixed arc 29 as the arm 19 rotates. The consequent rotation of the shaft 25 operates an eccentric switch to cut out the servomotor and possibly the electromagnet 18 and may also depress a plunger 40 into a cylinder 39, forcing air out of the hole 43, the resistance softly braking the movement of the arm 19. Manual or other mechanical means may be used in place of a servomotor. The parts of the arcs 13, 14 facing one another should preferably be toothed, knurled or coated with material of high coefficient of friction such as rubber. In a modification, Fig. 6, to test the deviation of an arm 9 coupled to an instrument, the cross-piece 15 is clamped and at the same time a motor 47 is started and drives a testing sector 19 until a switch 35, 36 carried thereon is opened by the cross-piece 15. Whereupon, a relay in the circuit causes the motor to reverse till the cross-piece 15 allows the switch to close again. Then a further relay stops the motor 47 and energizes an electromagnet 50 which, through an arm 49 and ratchet 48 stops the sector 19, while a claw coupling 46 yields, allowing the motor 47 to stop gradually.

Title: Process for coking hydrocarbon oils
IPC: C10G9/28
Filed: 1957-10-29
Abstract: 848,987. Coking. ESSO RESEARCH & ENGINEERING CO. Oct. 29, 1957 [Dec. 5, 1956], No. 33763/57. Class 55 (1). In a process of coking heavy oils by contacting the oil feed, entering at 27, with hot particulate solids, entering through riser 26, in a transfer line reactor 1, the product stream being separated at 3 into gaseous conversion products and solids, the solids are passed into one section 9 of a hold-up vessel 6. Solids are withdrawn from the section 9 through line 11 and passed, together with oxygen-containing gas entering at 13, to a heating zone, such as a transfer line burner 18, the effluent from which is separated at 20 into waste gases, which pass off at 21, and heated solids, which descend to section 10 of the vessel 6. The heated solids from section 10 are passed back to the transfer line reactor 1. The partition 7 in vessel 6 is of such a height that any disturbance of the system which affects the solids distribution causes solids to overflow from one section of vessel 6 to the other and thus restore the balance. Steam may be passed through lines 29, 30 to maintain the solids in sections 9, 10 in a fluidized condition. Some of the coke produced may be withdrawn by outlet 28 and extraneous fuel fed by line 15 into burner 18. The off gases from vessel 6 are removed by line 31 and may be sent through line 34. Alternatively they may be sent through line 32 to burner 18, auxiliary air being also introduced by line 16. In another mode of operation, the off gases pass through line 33 to discharge into the product stream from reactor 1. In an example the temperatures in degrees Fahrenheit of the solids are 1100-1500 in section 9, 1300-1600 in section 10 and 1200-1600 in riser 26, the reaction temperature being 1100-1500. The average residence time in the transfer lines 1, 18 is 0.1-5.0 seconds and the particulate solids are coke of less than 1000 microns in size and averaging 200 microns. The process may also be used with fluidized bed coking.

Abstract: 1479253 Locating internal body positions SIEMENS AG 13 Aug 1975 [11 Sept 1974] 33798/75 Heading A5R. Apparatus for use in penetrating into an interior body region 6 comprises a device for forming an image of the region on a viewer 9, an aiming device associated with the viewer, which can be aimed towards the location of a selected point 11 of the image and a device for directing e.g. a cannula into the region, this device comprising a guiding device which is adjustable to the adjusted aim of the aiming device to disect the cannula to that part of the region corresponding to the selected point of the image. An ultrasonic body scanning and echo sensing applicator 1 has a parabolic reflector 2 with a displaceable and rotatable ultrasonic transmitter/receiver head 3 on its focal line. The applicator is placed on a body surface in line with the region 6, an emitted ultrasonic beam 7 scans a plane of the region the ultrasonic echoes are picked up by head 3 and an image produced on a screen 8 of an oscillograph 9. The aiming device comprises an aiming pin 12 longitudinally displaceable in a displaceable guiding sleeve 13 pivotal about an axis 14 transverse to the pin, and an angle scale 20. A distance scale 21 for indicating the longitudinal pin position is provided along the pin. The guiding device, detachable from applicator 1, has a tool guiding sleeve 23 of the same length as sleeve 13 and similarly rotatably mounted about pivot axis 24, the device also having an angle scale 30 permitting the angular position of sleeve 23 to be set in accordance with that of the aiming pin 12 indicated on scale 20. Cannula 22 has a distance scale 31 so that the cannula penetration depth may be set in accordance with the longitudinal position of pin 12. A penetration limiting stop may be provided. Thus, the geometrical relationship between the pivot axis 14 of the aiming device and a selected point, 11, of the image can be coordinated with that between the pivot axis 24 of the tool guiding device and the corresponding body region point. Alternatively an applicator having several ultrasonic transmitters/receivers actuated chronologically may be used. Alternatively or additionally means may be included to monitor aiming of the aiming device and to control an automatic adjustment of the directing device, by sensing changes in the angular or longitudinal pointer position and providing corresponding control signals for the adjustment of the cannulas guiding device e.g. resistance potentiometers or photo scanners.

Title: Improvements in or relating to multi-speed gears for motor vehicles
IPC: F16H3/08
Filed: 1938-11-21
Abstract: 521,703. Change-speed gearing. AUTO UNION AKT.-GES. Nov. 21, 1938, No. 33854. Convention date, Nov. 20, 1937. [Class 80 (ii)] On a vehicle, particularly a motor-cycle, four constant-mesh gear-pairs yield six ratios, including one overdrive, two of the gear-pairs 19, 26 and 18, 27 constituting a two-speed gear which is under control of a double claw-clutch 21 splined on a final hollow driven sleeve 16, and is driven at any of three ratios under control of a third gear-pair, the wheels 6, 12 of which are in constant mesh and slide axially together respectively on a driving shaft 1 and a countershaft 4. The fourth gear-pair comprises a wheel 3 fast on the driving shaft 1, and a wheel 5, loose on the countershaft 4. In position I of the gearpair 6, 12, the wheel 6 is loose on the driving shaft, its splines 7 being clear of those 8 on the shaft, whilst the wheel 12 is dog-clutched at 14 to the loose wheel 5 and is also connected to the splines 11 on the countershaft 4 which latter is thus driven at its lowest speed. In position II the splines 7 of the wheel 6 engage those 8 of the driving shaft 1 and the dog-clutch 14 of the wheel 12 disengages that of the loose wheel 5, so that the countershaft is driven at a higher speed through the sliding pair 6, 12. In position III, extreme right, the wheel 6, still splined to the driving shaft 1, dog-clutches the wheel 19 at 10, whilst the splines of the wheel 12 come out of engagement with those 11 of the countershaft 4, so that the wheel 19 is directly connected to the driving shaft 1 and is driven at its highest speed. In each of these three positions of the gear-pair 6, 12, two positions of the claw-clutch 21 are possible, yielding six ratios in all.

Title: Improvements in the destructive hydrogenation of carbonaceous materials
IPC: C10G1/06
Filed: 1930-11-14
Abstract: In the destructive hydrogenation of solid carbonaceous materials mixed with high boiling hydrocarbons, the products are separated from solid residues and low boiling hydrocarbons, then freed wholly or partially from asphaltic products, and used again for mixture with fresh solid material.  The solid residues may be separated by filtration or centrifuging, if desired with addition of a solvent; the fraction rich in asphalt may be isolated by p  distilling off the ligher products in vacuo or with hydrogen under pressure, or by flocculation with hydrocarbons rich in hydrogen; it may then be treated with hydrogen at elevated temperature and pressure in presence of a catalyst, preferably finely divided or colloidal oxides of metals of the 6th Group.  The asphalt is thereby converted into hydrocarbons.  Examples of the treatment of soft coal and mid-German brown coal are given.
