Title: Improvements in or relating to finish-cutting of metal surfaces
IPC: B24B5/04
Filed: 1941-02-11
Abstract: 544,213. Milling-machines. HOWDEN, J. R. (National Broach & Machine Co.). Feb. 11, 1941, No. 1875. [Class 83 (iii)] A machine for shaving surfaces on a work piece W, Fig. 1, has one or more tool carriages each carrying a rotary tool spindle driven by a motor which is mounted on the carriage and also drives the mechanism for reciprocating the carriage. The frame 700 has an oil receptacle 701 and a column portion on which are mounted an upper headstock 703 and a tailstock 702 which is adjustable along ways 706. The tail centre is operated by a lever 705. The headstock is rotated from a motor 712 through V-belt gearing. The motor has friction relay means 716 for quickly stopping whiten it is de-energized. A second motor 717 drives a coolant pump 719 and is preferably controlled concurrently with the work drive motor. The tool slides 720, 721 carry shaving cutters 722, 723 which are fed by a plunge cut into the work W by tool slide movements in the direction of arrows 724, 725. Each cutter is of double conical shape and is adapted to finish a pair of adjacent surfaces on the work. Each cutter is fed into the rapidly rotating work at a rate which is decreased as full depth is approached. After a dwell the cutter is finally withdrawn. Each tool-slide comprises a slide 733, Fig. 8, mounted on a guide portion on the frame and having a guide 736 for receiving the main carriage 737. The lower slide 733 is adjusted on the base by a screw and carries a stop device 747 fitted with bolts for limiting the withdrawal movements of the carriage 737. The slide 733 carries posts 750, 751 having rounded upper portions coacting with feed and return cams 755, 757, respectively. The cams are mounted on a shaft 758 and the carriage is spring urged to the left to maintain the post 754 in contact with the feed cam, the return cam ensuring positive withdrawal independently of the spring action. The tool slide carries a housing 767 for the tool spindle driven from the motor 775 through a pinion 781 geared to a shaft 773 connected by belts 771 to the tool spindle. The tool spindle is also connected to a shaft 792 which through worm gears 793 drives the cam shaft 758. A cam 800 on this shaft actuates a relay 801 through an arm 802. The motor 775 is mounted on a platform 806, Fig. 5, pivoted at 807 to an arm on the tool slide, the platform being adjustable about the pivot to tension the belts 771. The motor drives through a belt 817 a friction relay 815 for instantly stopping the motor on completion of a cycle. The two relays 801, one for each slide, are arranged to stop the respective tool motors but the work and coolant motors continue to run until both the tool motors have stopped. All the motors are started simultaneously by a starting button control.

Title: An improved method and apparatus for testing and sorting lenses
IPC: G01M11/02
Filed: 1959-01-20
Abstract: 909,383. Photo-electric lens sorting. KODAK Ltd. Jan. 20, 1959 [Jan. 27, 1958], No. 2049/59. Class 40 (3). In an arrangement for testing and sorting lenses according to their image producing quality each lens is arranged to cause a narrowline light-image to move along a sinusoidal aperture in an opaque member and so produce via a photo-electric device, a modulated electric signal the extent of which with respect to a predetermined level is arranged to operate a mechanical device to separate the lenses into two groups indicative respectively of modulations above and below the predetermined level. The invention is described in connection with the testing and sorting of lenses (Fig. 1, not shown) which are moulded integrally with a mount provided with surfaces which coact with surfaces on a camera to which the lenses may be attached so as to position the lenses correctly with respect to the film plane. As shown in Figs. 2 and 3, the lenses 10 (Fig. 3), are positioned on inserts 22 (provided with suitable coacting surfaces) carried by a plurality of holes in a rotatable disc 20 so arranged with respect to an illuminated slot 32, an apertured opaque member 35 (see also Fig. 4) and a photoelectric device 41 (Fig. 2) that, as disc 20 rotates, an image of the slot 36 (Fig. 4) focused by the lens through a hole 23 in the inserts 22 (equivalent to the diaphragm of the camera) is traversed along the sinusoidal aperture in member 35 (Fig. 4) and generates a corresponding signal via photo-electric device 41, the degree of modulation of the signal being a maximum when the slot image is sharply focused (indicating correct relative positions of the moulded coacting surfaces and the lens and freedom from flaws in the latter). This signal is then employed to control a solenoid 62 which, is energized when an acceptable lens is in the " test position " and not energized when the lens is defective thus preventing or allowing, respectively, by means of an armature 61, which is pulled down when the solenoid is energized, the rejection of the lens into a bin 60 by theo peration of that one of a number of " flipper " springs 46 adjacent the test position which, when the solenoid is not energized, is allowed to ride up in a cut-away portion 52 in a fixed member 50 to eject the lens into a bin 60. When the lens is acceptable the armature 61 retains the spring and the lens remains in its position until it reaches a second cut-away portion 53 at which the spring is released and ejects the lens into a bin 63.

Title: Haymaking machine
IPC: A01D78/12
Filed: 1972-01-17
Abstract: 1373713 Haymaker MASCHINENFABRIK FAHR AG 17 Jan 1972 [16 Jan 1971] 2082/72 Heading A1F A haymaking machine has a tine carrier 4 which is axially and pivotably displaceable about support member 3 and tines 5 can thereby be brought into and out of engagement with harvested material so that a swath is formed. The tines are held in a horizontal position Fig. 3 when inoperative but they move to a vertical position Fig. I when rake wheel 1 is rotated. Since centrifugal force urges tine carrier 4 outwards against return spring 14. Guide rod 6 joins support member 3 to tine carrier 4 via ball joints 7, and moves so that tine carrier 4 is pivoted about the longitudinal axis of the support member. Pivotal movement is limited by stop 9 on the tine carrier cooperating with stop 10 on the support member. An eccentric wheel 12 is rotated via cable 13, and at the position where the swath is to be formed the distance between the securing point of the cable on the eccentric and on the tine carrier is at its greatest, with the effect that the cable pulls the tine carrier inwards. The tines are briefly pivoted upwards and the harvested material is released from the tines and piled into a swath. Damage due to over-loading is reduced because the tines can yield against the centrifugal force. The tine carrier can be mounted in a sleevelike bearing which is firmly connected to boss 2 of the rake wheel. The tine carrier can also be mounted on the support member of the rake wheel so as to be pivotable but not axially displaceable. Axial movement of a centrifugal weight, which is hingedly connected to the tine carrier by the guide rod, causes the tine carrier to rotate.

Title: Sulfoxidation process
IPC: C07B45/02
Filed: 1964-01-21
Abstract: Non-aromatic sulphonic acids are prepared by reacting a non-aromatic feed with oxygen and SO2 in molar excess of the oxygen, in the liquid phase, quenching and reducing the so-formed persulphonic acids with an aqueous medium in the presence of SO2, separating an aqueous phase containing the sulphonic acids so produced from unreacted feed, the latter being then contacted with 1 to 100 moles H2SO4 per mole of water contained therein and recycled to the reaction zone, and the product sulphonic acids being recovered from the aforesaid aqueous phase.  Suitable non-aromatic feedis C4 to C32 saturated straight-chain hydrocarbons, which may contain secondary carbon atoms, but a tertiary or quaternary carbon content below 10 moles per cent, or may be cyclo paraffins or mono-olefins above about 10 C, or polymerized olefins.  The gaseous reactants should be substantially anhydrous and comprise a molar ratio of O2:SO2 of at least 1:2.  Pure oxygen, air, or other sources of free oxygen may be used.  The reaction is appropriately initiated by ionizing radiation, from an X-ray machine, isotopes, or a b -ray machine, or by ultra-violet light, or chemically by, e.g., azo-compounds, diacylperoxides, ozone, lauryl peroxide, lead acetate, or peroxy-sulphonic acids.  Suitable reducing, quenching agents are water or aqueous alcohol in the presence of SO2, at 110 DEG  to 125 DEG  F.  An example of the process employs n-hexadecane as a feed; also two comparative examples are given in which (1) the unreacted n-hexadecane is not treated with H2SO4 before re-cycling, and (2) in which H2SO4 is used instead of an aqueous medium to quench and reduce the persulphonic acid reaction product.
