Title: Method of and apparatus for automatically conditioning a lap
IPC: B24B53/02
Filed: 1954-12-13
Abstract: 769,928. Lapping. VOYTECH, C. F. Dec. 13. 1954 [Dec. 18, 1953], No. 36027/54. Class 60. A method of conditioning a rotatable lapping surface to coincide with a predetermined contour comprises providing a plurality of rotatable rings for abrading the surface to be conditioned with one side of each ring resting upon said surface and providing a common weight which is adjusted to be supported by a plurality of contact points between itself and the other side of each of at least two of the rings, the arrangement being 'such that only when the surface has the predetermined contour is the weight supported by the rings through all the contact points simultaneously. A lapping machine comprises a stationary base 10 on which is mounted for rotation about a vertical axis a lap 11 having an upper annular operation surface 12 which may be flat, convex or concave. Workpieces, e.g. discs 13. are placed within the confines of conditioning rings 14 resting on the surface 12. The rings 14 are held against revolution with the surface 12 but rotate about their own axes, as also do the workpieces. The rings 14 overlap both the inner and outer peripheries 15. 16 of the surface 12. The upper surface 34 of each ring 14 is recessed to form a shoulder 35 on which is mounted a race 36 of an anti-friction bearing 37; the other race 38 supports a ring-like end 39 of a heavy substantially rigid bar 40, the other end 41 of which is likewise ring-like. The opening 42 in the ring 14 is preferably smaller than the opening 43 in the end 39 of the bar, so that the workpiece 13 can be placed in ring 14 through the opening 43, and the stationary end 39 does not touch any article within ring 14 which might be high enough to extend into opening 43. Lugs 44 formed on the ends of the bar 40 extend into guides 45 secured to frame 10, so as to permit free vertical movement of the bar but to restrain it from revolving with the lapping surface 12. Contact end 39 of bar 40 with race 38 is established on one side by the end 46 of a bolt 47 threaded in opening 48 in bar 40, the bolt being locked by a nut 49. The side of race 38 diametrically opposite bolt 47 is contacted by the rounded end 53 of an adjustable screw 50 having a knurled head 51 and a graduated shank 52 co-operating with a scale 54 secured to end 39. In operation, any tendency for the lapping surface 12 to depart from the desired contour as defined by contact points 46, 53 will be immediately corrected by the transfer of weight of bar 40 from the low region to the high region. A bar identical to bar 40 co-operates with the conditioning rings disposed on a diameter located at ninety degrees from the diameter on which bar 40 is located; the crossing of the bars is preferably effected in a manner to avoid contact between the bars. In place of two crossed bars, a single weight may be used, the ends of the weight being formed with openings similar to the open ends 39 of bars 40. Lapping compound is fed to lap surface 12 from a tank 57 e.g. by gravity along a wire 55.

Abstract: 792,253. Racks. FIECHTER, E. Dec. 19, 1955, No. 36319/55. Class 52(5) The loop 8 of the fastening element 1 of a suspension device similar to that disclosed in Specification 708,989 is located in a closed recess in the holding element 7. The recess, formed as a bore in a synthetic plastic holding element and opened by a saw-cut for insertion of the journalled loop 8, is closed and welded when the holding element is heated and bent to shape. In a modification in which two holding elements are connected by a horizontal cross bar one shank 2 and end part 5 of each fastening element 1 are replaced by a head upset after the loop 8 has been inserted in the bore; without opening the bore by a saw cut, and the other end part 5 is extended-to engage an adjacent aperture 3 in the plate 4. In a further modification the loop 8 is rigidly embedded in the holding element.

Title: Improvements in throttle control for internal combustion engines
IPC: F02D9/00
Filed: 1932-12-23
Abstract: 412,262. Spray carburetters. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Dec. 23, 1932, No. 36426. Convention date, Dec. 28, 1931. [Class 7 (iii).] Means are provided which maintain the mixture throttle partly open during starting, but automatically move it to idling position when starting has been effected. Stalling of the engine is also prevented, as the device operates automatically to move the throttle to the partly open position when the engine tends to stop. Fig. 1 shows the throttle 3 actuated by an arm 6 connected to the usual control, an arm 9 loosely mounted on the throttle spindle 4 being connected to a piston 16 subjected to the suction in the inlet manifold by a pipe 18. When starting the engine, the throttle is held in the partly open position shown by a spring 14 acting on the arm 9, which bears through an adjustable stop 8 on a projection 7 on the control arm 6. After starting has been effected, the engine suction acting on the piston 16 overcomes the action of the spring 14 and allows the throttle to close to idling position. This latter position is regulated by an adjustable stop 12, and a further adjustable stop 21 regulates the starting position of the throttle. In a modification, Fig. 5, the throttle is made in two parts 24, 26 movable relatively to one another between stops 27, 28 by a spring 32, the effect of which is overcome, and the two parts of the throttle brought into alignment, by the engine suction when starting has been effected.

Title: Improvements in the production of unsaturated hydrocarbons
IPC: F02B3/06
Filed: 1955-12-21
Abstract: <PICT:0792604/IV (b)/1> A process for the production of unsaturated hydrocarbons such as acetylene and ethylene and higher olefines consists in cracking liquid hydrocarbons with the aid of electric arc discharges between electrically conducting granular solid substances which are dispersed in a loosened condition in the liquid hydrocarbons to be cracked and circulating the liquid hydrocarbons upwardly through the solid particles situated on a grate with such a velocity of flow that the particles move in a loosened, suspended condition in the liquid.  The solid granular substances may be coke, wood, charcoal, electrode carbon, graphite, copper and other metals or metal alloys.  Silicon carbide, ferrosilicon, copper oxide, cuprous oxide, iron oxides, magnesium oxides, alumina and quartz may be present to enable the resistance to be increased. Agitation of the particles is caused by means of a liquid or gas such as methane, steam or nitrogen.  In an example, a mixture of graphite granules and quartz gravel is placed in container B made of sheet iron and an electrode E1 projects into the solid to a depth of about 5 cms.  A second electrode E2 is fitted to the side of the container which is filled with Diesel oil.  Gaseous products leave at Ga, and liquid products which leave by line Gi and pass through filter F may be recycled together with fresh liquid through Ge.  The product consists of acetylene 30-32 per cent, ethylene and higher olefines 8-12 per cent, methane 5 per cent and hydrogen 50-55 per cent.

Abstract: 374,887. Fastenings with seals. BARKER, J. P., 24, St. Vincent Road, Wallasey, Cheshire. March 7, 1931, No. 7117. [Class 44.] The bolt D, Fig. 4, of a ticket punch A similar to that described in Specification 374,888, [Group XIX], is retracted by inserting in the left-hand side of the aperture b<4> a pointed tool or pin which pierces a seal in the slot b<5> and then enters the aperture c<4> of a slidable sleeve C which is moved to the right against the spring c<3>, the tool defaces the seal, enters the recess d<5>, and moves the bolt D to the right, against the spring d<3>, to unlock the door B of the punch. A pin b<3> limits movement of the sleeve C and bolt D. The axial movement of the bolt D is limited to a small amount to permit a snap-like action of the bolt in closing without having an unnecessarily long bevelled portion d<7> on the bolt. To provide against omission to insert the seal a magnetic lock is fitted, comprising a hollow disc e<2>, Fig. 2, having a tail piece e<1> and pressed in a suitable recess E by a flat spiral spring e3 so that the tail piece e<1> engages a fixed projection e4 carried from the door &c. prevents the opening thereof. When the bolt D has been withdrawn in the manner above described the punch casing is brought under the influence of a powerful magnet which attracts the disc e<2> and withdraws its tail piece e<1> from engagement with e<4>, thus permitting the door to be opened. The member C may take other forms than a sleeve, e.g. sliding or pivoted shields according to the Provisional Specification. Specification 152,390, [Class 106 (iii), Fares &c.] also is referred to.
