Abstract: 1328052 Colloidal fibrous bochmite BAYER AG 2 Feb 1972 [3 Feb 1971] 4904/72 Heading C1A AlO(OH) is produced from active aluminium oxide, having a residual water content of 2- 15% which is obtained by the incomplete dehydration of hydrated alumina, by reacting in an aqueous slurry with a monobasic organic acid to give the corresponding basic Al salt which is subsequently subjected to hydrothermal treatment at 120-200‹ C. and 2-15 atmospheres in an aqueous suspension have a concentration equivalent to 2-20% by weight of Al 2 O 3  until a colloidal fibrous boehmite solution has been formed. The active aluminium oxide may be obtained by rapid dehydration of the hydrated alumina in a turbulent stream of gas at 400- 800‹ C. and it may be converted by heating with the organic acid on the boil until constant viscosity is reached. The preferred acids are formic and/or acetic acid and the preferred molar Al : acid ratio is 1 : 0À5 to 1 : 3. The fibrous boehmite may be thickened by evaporation whilst reducing the acid : Al 2 O 3  ratio and then dried to a powder which still contains water of hydration. The product is used in ceramic, fillers and textile auxiliaries.

Abstract: 389,640. Ironing-presses. HOLTTUM, W. R., 95, Ashburnham Road, Luton. Feb. 19, 1932, No. 4985. [Class 138 (ii).] In a press particularly for ironing collars and cuffs which are placed on a support raised into pressing engagement with a stationary press head by means of a fluid-pressure operated ram, the work being placed on the support when the latter is out of alignment with the head, and wherein the support is moved manually into alignment with the head, which movement automatically renders operative the fluidpressure means, means are provided which normally obstruct the movement of the work support to the position of alignment and which must be manually removed before the support can complete such movement. The support 32, Fig. 1, is provided with a vertical pillar 24 slidable in a boss 25 formed on a plate 26 secured to the upper end of a rod 12 which is. secured at its lower end to a crank 20 rockable about a shaft 21. Arms 62, Fig. 3, are pivoted on the plate 26 and are normally drawn together at one end by a spring 65 so that when the work support is drawn forward out of alignment with the stationary head 33 these ends contact with a block 66 on the upper end of the pressure cylinder 4 and prevent the support from being moved into alignment with the head until the arms are moved apart by manipulation of handles 61 at their other ends. As the support reaches the position of alignment an abutment 11, Fig. 1, on the rod 12 opens a fluid-pressure supply valve 10 and the ram 3 raises the work support into pressing engagement with the head 33. In a modification, Fig. 4, a pin 44 is normally projected across the inner ends of the limbs of a bifurcated guide 42 in which the rod 12 works. In order that the rod 12 may complete its movement to move the work support into alignment the pin must be retracted against its spring 53 by means of a manually operated bell-crank lever 46. In both forms the outward movement of the rod 12 is cushioned by a spring-pressed pin 41.

Abstract: 900,125. Making curved shoots. GOODALL, CLAYTON & CO. Ltd. Feb. 8, 1961 [Feb. 12, 1960], No. 4988/60. Class 83 (2). A method of making a curved shoot for granular materials includes the steps of calculating the true plan angle from the apparent plan angle of a given bend, developing the required shape in the flat of one or more plates, bending or pressing the plates so that their resultant cross-sectional contours in planes at right-angles to the longitudinal axis of the ultimate curved shoot are circular arcs, and joining the plates side by side along the length of the shoot, whereby no twisting of the plate material is necessary to achieve the required finished spiral effect. Details are given of the steps involved in determining the developed shape in the flat of six plates which when welded together form a shoot which is 2 feet 6 inches in diameter, has an apparent plan angle (transfer angle) of 110 degrees and in which each end is inclined at 21 degrees. In a modification, two shoots are formed from a closed bend made from two parts welded together along their longitudinal edges W 1 , W 2 , W 3 , W 4 . The shape of these plates is calculated by conventional methods and they are hot-pressed before welding. Details are given of the method of marking out the closed bend so formed so that it may be cut along lines extending from D and E to give two shoots of the same hand with the required angle of inclination at the ends.

Title: High speed digital tracking system
IPC: H03M1/00
Filed: 1972-02-04
Abstract: 1370955 Reducing lag in measuring INDUCTOSYN CORP 4 Feb 1972 [5 Feb 1971] 5213/72 Heading G4H In measuring the contour of a surface on a machine tool inspection machine, lag between a digital output and the instantaneous actual position of the measuring probe is reduced by a second order servo-system responsive to any error between an electric signal F(y) and the actual position F(x) and to the first derivative with respect to time of the error, to adjust the electric signal F (y). As shown in Figs. 2 and 3, pulse-width modulated signals representing sin y and cos y are fed on lines 48 and 49 to the movable member 41 of an inductive position sensing transducer connected to be moved by the probe. The transducer output from its stationary member 40 is phase detected at 93 to provide a D.C. error signal a sin (y-x) on line 50. Its first derivative and the square of the first derivative are derived, Fig. 4 (not shown), and added with weighting to give an analogue control signal which, if positive, passes binary 1 and 0 signals on lines 77 and 78 respectively to integration control means 53. A pulse train of frequency representing an acceleration d<SP>2</SP>F(y)/dt<SP>2</SP> from source 38 is integrated in a velocity counter 55, pulses reaching the counter via "up" line 80 or "down" line 81 according to the signals on lines 77 and 78. A frequency selector 59 selects an appropriate frequency from counter 60 and sends out on lines 83 and 6 a pulse train RCT of frequency proportional to dF(y)/dt. A zero detector 88 detects when the velocity count is zero to control Up/Down signals on line 5. The count in external counter 32 is changed accordingly and passed on to a display 34 and a computer 35 including a store. Also, each time a pulse is received on line 6, control means 7 causes the difference in count between two counters 11 and 12, stepped in synchronism by clock 21, to change by 1, said difference therefore representing F(y) which is converted to pulse-width modulated signals at 17. Three systems may be used for measurements along three axes.
