Abstract: 726,544. Making bushes. AEROQUIP CORPORATION. Jan. 22, 1953 [Nov. 25, 1952], No. 1922/53. Classes 83 (2) and 83 (4). Assembling force fits.-A force fit between a bushing and a hole in another member is effected by providing the bushing with a leading pilot portion of a diameter approximating the hole in said member and a hole broaching portion adjacent said pilot portion, said broaching portion having an external surface defined by longitudinal splines which provide leading ends with cutting teeth. To form a bushing 10 a metal blank is first machined to a diameter equal to the hole in which the bushing is to be inserted and annular chip grooves 14 are cut in the machined blank. Stepped broaching portions 16 and 18 having splines 20 are formed by a broaching operation which increases the diameter of the blank across the splines by approximately 0.003 to 0.005 inch. The blank is drilled and reamed and cut to length and finally accurately ground to provide the required difference in diameter between the pilot 12 and the broaching portions 16 and 18. The recesses 22 are of greater cross-sectional area than the splines 20 and the diameter across the recesses is less than the diameter of the hole. The pilot accurately aligns the bush in the hole and also provides a retaining wall for the chips resulting from the broaching operation of the splines 20. A wedging accumulation of chips is thus provided by the pilot and the wall of the reamed hole for assisting in the self-staking of the bushing in the hole. Several broaching portions may be provided if necessary and the bush may have a helical chip groove 14<SP>1</SP> (Fig. 4).

Abstract: 152,254. Page, S. E., (Manby, A. E.). Jan. 24, 1920. Cameras with connected action betweem shutter and changing mechanism.-To prevent a second exposure of the same film, a catch springs behind the shutter lever preventing it from returning to normal position, and is retracted and re-positioned by the film-winding mechanism. In one construction, the catch comprises the end e, Figs. 1 and 2, of a flexible wire a in a casing a<1>. The other end b of the wire engages the flange c of the spool d, which compresses and slightly buckles the wire and thereby presses the end c against the shutter lever f. On making an exposure, the catch e springs behind the lever, preventing it from returning until on winding the spool d the end b enters the notch j in the flange c under the action of the spring a<2> in the casing a<1>, and thereby temporarily withdraws the end e, allowing the lever f to return to normal position. Modified constructions are described, in one of which the end b is pressed by a spring fixed to the camera casing and is released by a pin on the flange of the spool. In another modification, the casing a<2> is extended to retract the pin e<2>. In another modification, the pin e, Fig. 9, is pressed by a spring 9 in a fixed casing. against the shutter lever, and is temporarily retracted to allow the lever to return by a flexible cord 1 connected to a loose flange 3 on the film spool axis. The flange of the film spool has a pin 5 which engages the trip arm 2 on the flange 3, the rotation of which is limited by a stop 10 and fixed projection 11, when the pin 5 slips past the end 7. The spring 9 restores the pin e and flange 3 to normal position.

Abstract: 1412328 Machine comparison of programs HONEYWELL INFORMATION SYSTEMS Inc 17 Jan 1973 [21 Jan 1972] 2441/73 Heading G4A A computer is programmed to compare a modified program with its base reference (original) program to identify any differences. Source program code from both programs is loaded into buffer stores for comparison line by line until a difference is found. The lines exhibiting the difference are moved to the top of the respective buffers, and the buffers are then re-filled with code from the two programs. Starting at the top of the base program buffer, lines of base program are compared with the lines of modified program in the other buffer until a match is found for two successive lines. A search is then made for identical symbolic addresses, i.e. a common point, in the two programs, and working back from this point, lines are compared, in the two prgrams, until an unequal comparison is found. The start and end of an area of change are then delineated from the positions of the first unequal comparison, the first equality of two successive lines or the first, backwards, inequality whichever gives the smaller area of change. By examination of statements within the area of change, a decision on whether the change is an addition, deletion or modification is made and an indication thereof is given on a print-out.

Abstract: 341,284. Couplings for road vehicles. SCHLAGENHAUF, J., 18, Mittelstrasse, Oerlikon, Zurich, Switzerland. Jan. 24, 1930. No. 2590. Convention date, Jan 26, 1929. [Class 79 (iii).] Relates to couplings between tractor and trailer road vehicles of the kind comprising on one vehicle a bell-shaped coupling socket 8 arranged to swivel in an horizontal plane and to receive a coupling eye 1 on the other vehicle, and a vertically dropping bolt 10 adapted to engage the eye 1 when the two vehicles are brought together. According to the invention, the socket 8 is held in its central position by a locking-bolt 16 which, upon entry of the eye 1 into the socket, is automatically pressed back, freeing the socket for swivelling movement and simultaneously bringing a reduced or grooved part of the locking-bolt 16 into the path of a pin 15, which is thereby permitted to drop under the action of a spring 12, actuating a lever 13 connected to the coupling-bolt 10. The socket 8 pivots on a bush 6 mounted in a casing 4, which is preferably integral with the draw-bar 3, and has a guide surface 5 for the eye 1. Normally, an enlarged part of the bolt 16 engages an enlargement 17 in a transverse slot in the socket 8, but is released therefrom during the act of coupling so as to allow the socket 8 to swivel with the draw-bar 2 of the opposed vehicle as shown in Fig. 3, e.g. in negotiating a sharp curve. A hand-lever 25 is provided for restoring the coupling-bolt 10 to its upper position, the bolt 16 being simultaneously moved forward to its looking position by a spring 26. In a modification the draw-bar 2 is cranked so as to prevent it from fouling the edges of the guide 5 during its swivelling movements; while, in a further modification, the eye 1 is disposed on a lever pivoted to the draw-bar 2 and centralized by springs.

Abstract: 475,611. Hydraulic shock absorbers. GENERAL MOTORS CORPORATION. Jan. 29, 1937, No. 2621. Convention date, Jan. 30, 1936. [Class 108 (iii)] In a hydraulic shock-absorber in which an inertia weight responsive to accelerations in the movement of the shock-absorber actuates a fluid control valve, a spring 95 is interposed between the valve and toggle joint for urging the valve to its closed position. As shown a cylinder 25 is formed in a casing 23 containing liquid and is provided with a plunger 40 operated by a cam 34 secured to a rocker shaft 30. The plunger is under the control of a spring 41 and is provided with a valve seat 46 and valve 47 pressed thereon by a spring 48. The valve is bored at the centre to form a relief passage normally covered by a valve 50 under the influence of a spring 51. The cylinder 25 is also in communication with the liquid in the casing 23 through ports 26, 27 and valve 61 which is held on its seat by the spring 95 adjustable on an arm 91 of a toggle 90, 91 pivoted at 92 to an inertia weight 75 pivoted at 74 and held in contact with a stop 76 by a spring 80. On an upward movement of the wheel the cam 34 moves clockwise and the plunger moves outwardly and admits liquid to the cylinder 25 through valve 46. On downward movement of the wheel the cam moves the plunger inwardly, the liquid. escaping through valve 61 into the chamber 23. If the valve 61 cannot properly relieve the excessive pressure in the cylinder 25 then valve 51 moves off its seat and relieves the excess pressure. If the vehicle frame is moving upwardly away from the axle at an accelerated rate then the weight 75 descends and the toggle is moved into its aligned position causing the valve 61 to move towards its seat and restrict the flow of liquid from cylinder 25.

Abstract: <PICT:0400915/III/1> Clays such as Keuper clays having base-exchanging properties are converted into a raw slurry with hard water of stated composition and then further diluted and allowed to stand, whereby impurities such as quartz are deposited, and an upper layer of purified slurry is formed.  2-4 per cent of common salt is added to the separated purified slurry, which on further standing thickens, and the thickened slurry is then treated with trisodium phosphate or again with common salt, dried, crushed and bolted, and finally baked at 800-900 DEG  C., the baked grains being hydrated with water at 100-200 DEG  C.  In the above treatments the purified slurry may be thickened with other alkali (including ammonium) salts, and the trisodium phosphate may be replaced by other alkali phosphates, or by alkali oxalates, borates, or silicates.  In treating clays low in impurities, the dilution and thickening steps may be omitted. For use in softening water, the treated clay 3 may rest upon a bed of gravel 2 in a cylindrical container 1 provided with a depending conical member 4.  Water enters at 6 and is discharged at 7.  By this arrangement, the formation of channels in the clay by the flow of water therethrough is stated to be minimized. German Specification 423,224 is referred to.
