IPC: F16D7/04
Filed: 1928-09-13
Abstract: 323,035. White, A. E., (Independent Pneumatic Tool. Co.). Sept. 13, 1928. Bolts, nuts, and screws, screwing-up and unscrewing; yielding-drive attachments.-In portable power driven machines or attachments for screwing- up or unscrewing nuts, screws &c., a tool-spindle is rotatably supported in the driving shaft of the machine and is driven therefrom through two clutches whereof one i s adapted to slip when the nut &c. is screwed home. In an electrically driven machine the armature shaft 6 drives the main shaft 4 through triple reduction gearing 11, 9, 7 enclosed in a casing 2. The shaft 4 has an axial bore in which is slidably and rotatably mounted the tool-spindle 12 which carries a removable spanner 45 or a screw-driver &c. For right and left hand screwing the tool 45 is secured by a keyed connection instead of the screw-thread shown. The spindle 12 has a clutch part 23 slidably keyed thereto by means of three sets of balls 24 kept in position by a washer 32 pressed upwards by a spring 31 which engages an adjustable abutment 33 on the spindle. The clutch part 23 is normally pressed by the spring 31 into engagement with an intermediate clutch part 16 rotatably attached to the spindle by balls 18, and having clutch teeth 17 on its upper surface corresponding with teeth 14 on a clutch part 13 attached to the shaft 4. A spring 37 in the bore of the shaft 4 normally maintains the clutch 13, 16 disengaged, with a part 23 resting on a flanged part 42 of a casing 41 attached to the gear casing 2. In operation, with the parts in the positions shown in the figure, the friction of the clutch 23 on the flange 42 prevents the spindle 12 from being rotated by the motor and the tool 45 may be engaged on the nut &c. Pressure on the device then engages the clutch 13, 16 and the tool is rotated until the nut is screwed home, whereupon the clutch parts 16, 23, whose teeth are bevelled more acutely than the teeth 14, 17, are separated against the pressure of the spring 31. The clutch parts 16, 23 continue to slip and give an audible signal until the device is removed from the work, some clearance being provided between the teeth and recesses of the clutch to allow blows to be imparted to the tool without imposing the) full torque of the motor on the operator. The spaces in the clutch 13, 16 are considerably larger than the teeth in order to facilitate complete engagement.

Title: Process for purifying aqueous hydrochloric acid
IPC: C07C17/38
Filed: 1962-07-10
Abstract: <PICT:1009036/C1/1> Aqueous HCl containing volatile contaminants is purified by treating with steam in counter current to evaporate and entrain the contaminants, and the steam is then contacted with water in counter-current to absorb any HCl also entrained in the steam. A packed column 1 is joined to another 2 by a port 3 and to a collecting vessel 5 by a heat exchanger 4.  The contaminated acid is heated to its boiling point and introduced at 6.  Water vapour rising from the evaporator 4 expels and entrains the contaminants, and purified acid is collected at 5.  The water vapour passes into 2 and boiling water at at least 60 DEG  C., preferably is introduced at 7. HCl is absorbed by the water and returns into column 1, the amount of water fed in at 7 being selected so that the concentration of this acid is 30-32%.  The water vapour removed at 8 may be condensed to recover the entrained contaminants, which may be Cl2 or aliphatic or aromatic hydrocarbons, or their chlorinated derivatives, e.g. 2 - chloropropylene, 3,3-dichloropropylene, 2-chlorpropane, and 1,2,3-trichloropropane. The purified acid may be used to preheat the feed at 6, or, where the purified acid is subsequently distilled, the hot evaporated acid may be used for preheating.

Title: Improvements in image recognition method and system
IPC: G06V30/144
Filed: 1958-08-19
Abstract: 873,156. Image recognition systems. GENERAL ELECTRIC CO. Aug. 19, 1958 [Aug. 21, 1957], No. 26625/58. Addition to 858,002. Class 40(3) An image recognition system includes an electronic curve follower as claimed and described in the parent Specification, in which the image is displayed, wherein an alternating signal is produced having a phase which represents the instantaneous direction of the tangent to the curve constituting the image, this signal being delayed by a fixed time and compared with the undelayed signal to derive the phase relation therebetween which is an invariant function representing change in instantaneous direction of the curve constituting the image. The alternating signal, representing by its amplitude and phase the velocity and direction of movement of the search circle Q of the curve follower, appears at the output of an amplitude control 49, and is resolved by phase discriminators 52, 53 into orthogonal components which are applied to audio delay lines 56, 57 and then re-combined into a polar co-ordinate which constitutes the delayed signal by balanced modulators 58, 59 and adder 60. The delayed and undelayed signals are fed to a phase discriminator 61 the output of which is the sine of the phase angle between the delayed and undelayed signals. This output is applied to the vertical deflection plates of a cathode ray tube 62 whilst a saw tooth sweep generator 63 is connected to the horizontal deflection plates. The spot on the cathode ray tube 62 traces out the resulting invariant waveform which is focussed by a lens 64 on to a stencil 65 which contains an invariant waveform derived in a similar manner for a standard curve. If substantial correspondence exists between the trace on the tube 62 and the waveform on stencil 65, a photo-cell 63 actuates a minimum pulse width discriminator 68 which triggers a recognition indicator 69. In a modification, Fig. 3, not shown, the output from the amplitude control 49 is fed to a frequency changer and low pass filter having an output at a lower frequency than the input but containing the phase information of the input signal. The output of the low pass filter is delayed by a magnetic drum delay and is fed to a phase discriminator to which the undelayed output of the low pass filter is also fed. The ouput of the phase discriminator is fed to the vertical deflection plates of the cathode ray tube 62.
