IPC: B01D53/14
Filed: 1970-05-11
Abstract: 1300669 Purifying cracked gases LINDE AG and ERDOLCHEMIE GmbH 11 May 1970 [10 May 1969] 22609/70 Heading C5E [Also in Divisions B1 and C1] In a process for removing CO 2  and/or H 2 S from cracked gases by absorption in a scrubbing column 2 using an aqueous alkaline solution which is regenerated in a column 7 and recycled to the absorber 2, resin-forming constituents of the gas which have been absorbed by the solution, e.g. dienes, higher acetylenes, and unsaturated polycyclic and heterocyclic compounds, are removed from the solution before or during the regeneration step. Several embodiments are described. In one, Fig. 1, steam generated in a reboiler 8 drives off CO 2 , H 2 S (which leave the plant at 13) and resin-formers from the solution in the column 7. Water and condensed resin-formers are wholly or partially discharged at 14, make-up water entering at 15. Hydrocarbons condensing in the column 1 are preferably removed from the absorbent before regeneration by dividing the sump of the column 1, see Fig. 2 (not shown), and allowing sparation by gravity of the aqueous and hydrocarbon phases in one chamber, with overflow into, and removal from, the other. In another embodiment, Fig. 3 (not shown), the absorbent is stripped, with CH 4 , N 2 , H 2  or process gas in a column (40) which is interposed between the column 2 and a heat exchanger 6. In Fig. 4 (not shown), the absorbent is extracted, at (20), with a liquid solvent which is recovered and recycled. In Fig. 5 (not shown), the absorbent includes an organic solvent for the resin-formers, sub-stream of the absorbent leaving the column 7 being separated, at (31), into an aqueous phase which is recycled to the circuit 9, 6, 10, and an organic phase from which the solvent is recovered and sent in the line 3. In Fig. 6 (not shown), the organic solvent is delivered to the column 7, separated from the aqueous phase in the sump of the column 7 by gravity, purified, at (24) and recycled to the column 7.

Abstract: 479,937. Pencil holders. MABIE, TODD, & CO., Ltd., JOHNSON, L. W., and SEARS, E. S. Aug. 17, 1936, No. 22639. Addition to 399,592. [Class 146 (iii)] In a pencil holder according to the parent Specification a sleeve is provided to act as guide for the lower end of the collet and derives its functional movement in both directions from the collet, and is slidably mounted and symmetrically supported in a member rigidly secured to the lower end of the pencil lining or casing and is formed with stops to coact with the member to limit the functional longitudinal movement of the sleeve. The collet 2 is formed with a reduced split lower portion provided with serrated jaws 45. The sleeve 1 is split at the upper end so that, by pressing the split sections together, it car be introduced into the bore of a collar 3, ir which it slides between limits provided by its flanges 42, 43. The collar 3 is secured to a lining 5, and is threaded at 11 for the attachment of a split tip 13. The rear end of the collet lies in a bore 25 in the end of a lead magazine 28. The magazine is closed by a socket 33 for a rubber 38a, with which socket engages the metal lining 40 of a cap 39. The collet is pressed rearwardly by a spring 22 arranged between discs 19, 20, and the movement is limited by a ledge 36 on the lining 5 engaging the socket 33. The rear end of the lining 5 is spun over to retain a pocket clip, (not shown). In a modification leads are stored between an inner star shaped lining 47 and an outer lining 48, and are introduced into the collet through a bore 57 in an operating knob 46. Rearward movement of the collet is arrested by the engagement of a ledge 53 or protuberances on the lining 47 with the disc 20. In either construction during the forward movement of the collet the sleeve 1 is carried by frictional engagement and the lead is fed until the sleeve is arrested by engagement of the flange 42, and collar 3. During rearward movement the lead is retained by the tip 13 and the collet is again clamped to the lead when the flange 43 on the sleeve meets the forward end of the collar 3.

Title: Improvements in or relating to thermally operated devices
IPC: H01H85/06
Filed: 1919-09-17
Abstract: 156,300. Vickers, Ltd., Dickenson, Sir J. H .C., and Sumpter, C. L . Sept. 7, 1919. Gearing for stopping machinery.-Relates to apparatus such as electric cutouts, electrically controlled motion devices, engine stop gear, and toothed gearing. A thermally operated device is dependent for its operation upon the rupture of a metallic material maintained in a condition of light stress and possessing the property of suddenly breaking at the melting point of a fusible metal or alloy in contact with it; such devices retain their rigidity right up to the operating temperature. A beta brass of simple polyhedral crystalline structure such as a manganese bronze of the composition copper 56 per cent, zinc 37 per cent, manganese 4 per cent, aluminium 2 per cent, iron 1 per cent is a suitable material, and a body of tinman's solder is placed in close contact with a member composed of such metal at the place where the fracture is desired. Excessive speed of a machine, for example an electric motor, may be prevented by means of a member r, Fig. 6, of manganese bronze, coated with fusible alloy or in intimate contact with a small mass of the same at a pivoted at one end and adapted to be heated at the other by friction with the rotating shaft u. The member r being under slight stress will break when it becomes overheated bv undue increase in speed, caused for example by a break in the field circuit, whereupon contacts v, w come together to close a circuit operating to cut off the armature current.

Filed: 1974-05-22
Abstract: 1462697 Engine control circuits NIPPONDENSO CO Ltd TOYOTA JIDOSHA HANBAI KK and TOKAI RIKA DENKI SEISAKUSHO KK 22 May 1974 [24 May 1973] 22948/74 Heading B7H An automatic vehicle engine control system including a starter energizing circuit 200, for activating a starter motor 4, a starter cut-off circuit 300 for disabling the motor 4 in response to engine rotation, a control circuit 100 for controlling the engine in response to the driving condition of the vehicle which circuit is coupled to a first switch 27 and a second switch 29 adapted to be sequentially operated by a clutch pedal to respectively operate the circuits 100 and 200 and a sensor 25 for detecting movement of the vehicle and for maintaining operation of the engine during such movement regardless of operation of the clutch. With the vehicle stopped and ignition and manual switches 2 and MS on, a self holding relay 10 is energized to connect the source 1 to the engine control system by way of a contact 11. Initial depression of the clutch pedal closes switch 27 rendering transistor 116 non-conductive and energizing relay 101 to connect the source 1 to the ignition circuit 3. Further depression of the clutch pedal closes switch 29 and transistor 204 becomes non-conductive so that starter relay 201 may be actuated along with starter motor 4. As the engine rotates voltage appears at alternator 305 and the starter relay 201 is deenergized to cut supply to the motor 4. On releasing the clutch pedal and depressing the accelerator, switches 27, 29 open and switch 26 closes thus maintaining the non-conductive state of transistor 116 and keeping relay 101 operative. A movement sensor 25 maintains operation during movement of the vehicle when the accelerator is released. When the vehicle is stopped on a level surface and the clutch released the engine stops automatically after a predetermined time. If the vehicle is arrested on a slope a level sensor 28 closes and the operative condition of the engine is maintained. Engine operation with the vehicle at rest may be continued regardless of the position of switches 27, 29 by accessory, reverse drive and turn indicator switches 21, 22, 24 which may be engaged at will. Furthermore if the engine temperature is above or below predetermined values the operative condition is maintained by a switch 23 regardless of all else.

Patent GB-757273-A (GB)
Title: Improvements in or relating to film feeding and positioning mechanism
IPC: G03B23/12
Filed: 1954-08-13
Abstract: 757,273. Optical projection apparatus. KODAK, Ltd. Aug. 13, 1954 [Aug. 13, 1953], No. 23577/54. Class 97 (1). In a film feed mechanism successive film areas are fed into a gate by a sprocket operated by Geneva mechanism, the striker pin member of which operates means to open the gate in advance of the feed movements and to close it after the movement has ceased. In the projector shown, the film is fed from a spool 30 downwards into the gate by a sprocket 34 rotated intermittently by a Geneva mechanism comprising the cross 40 and striker pin disc 50 rotatable by a knob 46. The gate comprises two apertured members 21, 22, carrying glass plates 26 for clamping the film, pivoted at 23 and urged together by a spring 28. Their upper parts 69 lie on either side of the flattened end 68 of the shaft 61 on which the knob 46 is mounted and by rotation of which the gate members may be separated. The disc 50 carries two striker pins, separated by 180 degrees, together with segments for locking the cross when stationary. The angular setting of the disc relatively to the flattened shaft end 68 is such that a 45 degrees rotation of the knob 46 opens the gate, a further 90 degrees feeds the film and a final 45 degrees closes the gate. The cycle then repeats. To permit initial framing of the film the cross 40 is mounted loosely on the shaft but is coupled to it by a friction disc 41 engaging a disc 42 rigid with the shaft. The sprocket is rotated by the knob 46 until a film frame is correctly positioned in the gate. A resilient brake member 73 is then depressed manually to engage the milled periphery 75 of the disc 42 while the knob 46 is rotated to a position corresponding to the start of the feed cycle. The knob 46 is in splined engagement with the shaft 61 and can be moved outwardly from the cross against a return spring within the knob. This disengages driving pins and locking segments from the cross. The knob is retained in the retracted position by latching members 83, 86 in an angular position such that the flattened shaft end 68 opens the gate. The film is then free for rewinding on to the spool 30 by the handle 33.

Title: Composition for treating meallic wear surfaces
IPC: C23C22/00
Filed: 1945-09-14
Abstract: Lubricating compositions for treating metallic wear surfaces subjected to frictional loading (particularly the cylinder walls, pistons and piston rings of internal-combustion engines) comprise water oil emulsions as hereinafter defined containing finely-divided graphite, a binder as hereinafter defined, a solvent for the binder, diluted ortho-phosphoric acid and an emulsifier.  The ratio by weight of graphite to binder is between 2 : 1 and 3 : 1 and the ratio of the weight of 100 per cent ortho-phosphoric acid to the combined weight of binder and graphite is between 0.10 to 0.80.  The emulsifier may be a substituted polyglycoletheralcohol and the solvent for the binder may be a mixture of xylol and coal tar naphtha.  In the example given, the composition consists of approximately 8 per cent by weight of binder, 12 per cent by weight of orthophosphoric acid (concentration 75 per cent by volume), 18 per cent by weight of finely-divided graphite, 37 per cent by weight of solvent, 23 per cent by weight of water, and 2 per cent by weight of emulsifier. The composition is prepared by mixing the binder and graphite with an equal weight of the solvent, adding the emulsifier and water to the phosphoric acid, mixing and violently agitating the resultant oily and aqueous liquids to produce an emulsion, and adding the remainder of the solvent.  The surfaces to be treated are thoroughly cleaned and sprayed with the composition to a thickness of about 0.0003 to 0.001 inches.  They are then preferably allowed to dry for several hours and baked for 30 to 60 minutes at 400 DEG  to 600 DEG  F.  This causes the phosphoric acid to react wth the metal of the cylinder surface to form a film of phosphate, firmly bonded to the surface, through which the graphite is uniformly dispersed.  The running-in period of high output aircraft engines whose cylinders have been treated as above is said to be reduced and the operation facilitated without scoring or scuffing of the wear surfaces.  The dispersion of graphite in the solution of binder in an organic solvent constitutes the oil phase of the oil-water emulsion and the diluted phosphoric acid the aqueous phase.  The binder is an organic material, such as a residual asphaltic petroleum bitumen and/or coal tar pitch, solid at ordinary temperatures, soluble in volatile organic solvents such as coal tar naphtha, insoluble in water, not completely volatile at temperatures of the order of 400 DEG  to 600 DEG  F. and having a bonding action with the graphite.  Specifications 599,161, [Group XXVI], and 609,726 are referred to.
