Abstract: 1,152,577. Purification of aromatic polycarboxylic acids. STANDARD OIL CO. 16 May, 1966 [17 May, 1965], No. 21656/66. Addition to 994,769. Heading C2C. An aromatic polycarboxylic acid containing undesirable aldehyde and other impurities is purified by a process which comprises contacting a solution of the impure acid in demineralized water in the liquid phase at an elevated temperature and pressure and in the presence of H 2  with a Pd-containing catalyst under mild hydrogenation conditions, and recovering purified acid. The aromatic polycarboxylic acid may be obtained by liquid phase catalytic oxidation of polyalkyl aromatic hydrocarbons. Specified polycarboxylic acids which may be purified are terephthalic, isophthalic, trimesic, trimellitic, mellitic and naphthalene dicarboxylic acids. The hydrogenation is suitably carried out at a temperature in the range of about 450-600‹ F., in an inert polar solvent either as a batch process under static conditions or as a continuous process maintaining a concurrent or countercurrent flow of H 2  through the catalyst chamber. A sufficient pressure may be maintained in a reactor by using a mixture of H 2  and an inert gas, e.g. N 2 . The product may be obtained from the reaction mixture by filtering and crystallizing from the filtrate. A process is described with reference to the accompanying drawings (not shown) for the preparation of terephthalic acid. Examples are given for the production of terephthalic acid showing the effect of using water of varying purity.

Title: Seat reclining mechanisms treating aqueous silica sols
IPC: B60N2/235
Filed: 1973-05-08
Abstract: 1422063 Locking hinges H R TURNER (WILLENHALL) Ltd 22 Feb 1974 [23 Feb 1973 8 May 1973] 8967/73 21765/73 and 47462/73 Heading E2F [Also in Division A4] A backrest adjustment arrangement which allows adjustments of smaller increment than the pitch of the interengaging teeth comprises a pair of parts 10, 11 e.g. for attachment to the backrest and seat cushion respectively, which parts are provided with teeth 16, 17. The set of teeth (17) which is more remote from the hinge axis is mounted for translational movement in a first direction transverse to the hinge axis towards and away from the axis so as to provide engagement and disengagement, and also mounted for translational movement in a second direction transverse to the first direction and to the hinge axis. User-actuable means are provided for effecting movement of the teeth between meshing and disengaged positions; during re-meshing the teeth 17 move in the second direction to accommodate any misalignment of the sets of teeth 16, 17. In one embodiment (Fig. 2) the parts are arranged as shown and operate as follows: A lever (not shown) is operated to turn link 27 clockwise which moves plates 28, 29 upwards. The plates 28, 29 after initial lost motion, then lift hinge pin 12 and therefore also lift wedge plate 13 and plate 10. Toothed sectors 16, 17 are thus separated and adjustment of the backrest is made. The lever (not shown) is now returned thus lowering hinge pin 12, wedge plate 13 and plate 10. If the teeth of 16, 17 are not in alignment, the wedge plate 13 is free to move horizontally inside aperture 14 in plate 11. After such movement, wedges 24 move downwardly in the downwardly narrowing gaps between wedge plate 13 and aperture 14 to lock wedge plate 13 in position. In a modification (Fig. 3, not shown) the pivotally mounted toothed member 17 is replaced by one which is permanently affixed to member 11. In another embodiment (Fig. 5) a lever 66 is rotated clockwise to draw wedges 62a, b out of engagement with the inner surface of aperture 55 and the outer surface of boss 54. Wedges 62a, b now bear against surfaces 65 to lift plate 50 to disengage teeth 51, 53. When lever 66 is returned teeth 51, 53 are re-engaged, plate 56 having lateral freedom of movement to overcome misalignment, and wedges 62a, b reoccupy their wedging positions. In yet another embodiment (Fig. 6) operating handle 142 displaces link 140 in direction C. Link 156 therefore pulls wedges 150 out of engagement with portions 149 of plate 114 and fixed guides 148; continued movement causes wedges 150 to abut against projections 158 to withdraw the teeth of plate 114 from teeth 118 to allow backrest adjustment. On returning handle 142, plate 114 is capable of lateral movement in case the two sets of teeth are misaligned.

Title: Proximity detector arrangements
IPC: F42C13/00
Filed: 1974-05-16
Abstract: 1507980 Proximity fuze MARCONI CO Ltd 14 May 1975 [16 May 1974] 21860/74 Heading H4D A missile proximity detector comprises a conductance fuze in which an oscillator, which is connected to a TX/RX aerial, is started by an enabling pulse and means is provided responsive to the buildup of the amplitude of the oscillator signal to detect the presence of a conductive body within a predetermined range of the missile whereupon energy reflected from the body is detected by the aerial and results in an increased rate of amplitude buildup. The presence of the conducting body is stated to affect the total conductance of the oscillator and hence the damping (Fig. 1, not shown). In Fig. 3, multivibrator 10 supplies a pulse (Fig. 2) to oscillator transistor 11 which in the absence of a target begins to oscillate at an amplitude V n  corresponding to the instantaneous noise voltage, and the amplitude increases exponentially until at a voltage V s , close to the saturation, is sufficiently large to cause the multivibrator to automatically switch state as at 2, Fig. 2. If energy is reflected from a target within the buildup period the combined oscillatory energy causes a faster buildup to cause the multivibrator to switch after a shorter time period 1, 2, whereupon the natural exponential increase in base voltage of transistor 13 suffers a premature fast positive excursion and thereby produces a step function proportional in amplitude to the increased rate of oscillator buildup. The step function is differentiated and then thresholded in circuit 15 wherefrom e.g. a detonating signal may be produced. Circuit 14 stabilizes the gain of oscillator 11. As the initial value of the oscillator buildup has a random value i.e. V n , the pulse length and hence the pulse repetition frequency is jittered.

Title: Improvements in or relating to micrometers
IPC: G01B3/18
Filed: 1944-11-08
Abstract: 584,345. Micrometer gauges. FELLOWES, H. G. Nov. 8, 1944. Nos. 21971/44 and 29498/45. [Class 106 (ii)] To enable the movable jaw of a micrometer to be more easily adjusted through the ratchet feed device when the micrometer is used in one hand only, a sleeve is provided which encompasses the thimble or barrel and has means enabling it to operate the jaw through the ratchet device. In one form the sleeve is an attachment fitting rotatably over the usual thimble, an extension of lesser diameter, which is externally screw-threaded adjacent the larger portion and formed with a split collet at the end fitting over the usual knurled head of the ratchet device. A collar which is internally threaded to fit the threaded extension of the sleeve and tapered to engage and contract the split collet to grip the head of the ratchet device is provided whereby rotation of the sleeve operates the ratchet feed. In another form, the micrometer itself is modified as shown by recessing the thimble 13, which is integral with the threaded barrel 15, for the reception of a sleeve 14 which is'a rotatable fit thereon and flanged at 16. A ratchet-device housed between the flange 16 and an extension I 7 of the barrel 15 comprises a toothed member 20 slidable against the action of a coil spring 24 along the extension 17, but not rotatable relative thereto, and a member 21 with teeth co-operating with those on member 20. The member 21 is formed with a tubular extension 52 extending through the flange 16 and externally threaded for the reception of a clamping-nut 26 and a locking-nut 28. A rod 18 screwed into the extension 17 passes through the tubular extension 25 and is provided with a cheese-head 19 lying within a recess in the nut 28. When the nut 28 is not engaging the head 19, the assembly comprising the sleeve 14, ratchet member 21 with extension 25 and nut 26 has freedom of movement with respect to the rod 18 and therefore the barrel 15, and rotation of the sleeve 14 then operates the barrel 15 through the ratchet members 20, 21. If the nut 28 is screwed back to bear hard against the head 19 of the rod 18, the assembly of parts associated with the tubular extension 25 (including the sleeve 14) become fixed relative to the barrel 15, and the latter is positively rotated on rotating the sleeve 14. The sleeve 14 may extend over the full length of the thimble 13 so that the thimble cannot be turned for positive rotation of the barrel 15 instead of using the sleeve 14 and ratchet-device.
