Patent GB-1553145-A (GB)
Title: Laundry drier
IPC: H05B3/14
Filed: 1977-11-10
Abstract: The laundry drier has a drier control and a PCT resistance heater. It should be possible to use the latter without elaborate additional devices, even at powers of about three kW. For this purpose, the heater consists of several PCT resistors which are arranged in a circuit limiting the switching-on current. The PCT resistors are switched over by the drier control, for example from the series circuit at the beginning of the drying program into a parallel or part-parallel circuit as a function of time or temperature.

Title: Synthesis of anatase tio
Inventor: SKRIVAN JOSEPH FRANCIS
IPC: C01G23/07
Filed: 1966-10-20
Abstract: Finely divided anatase TiO2 is prepared by the vapour phase oxidation of a volatile titanium salt in the presence of boron or a boron containing compound; the latter may be present at from 0.1 to 10% by weight of the TiO2 produced and may be BF3.  A nucleating agent, e.g. AlCl3 may be present with the reactants.  The percentage of anatase in the product may be varied by altering the proportions of BF3 and AlCl3, larger proportions of the latter leading to a lower anatase content.

Title: Viscous fluid damper
IPC: F41G11/00
Filed: 1974-10-31
Abstract: 1482938 Rotary viscous fluid dampers HUGHES AIRCRAFT CO 31 Oct 1974 [31 Oct 1973] 47203/74 Heading F2S A fluid damper comprises relatively rotatable annular damper surfaces 12, 18 providing between them a narrower gap and a wider gap containing a damping fluid of high viscosity, with the narrower gap being farther from the axis of rotation. The fluid may be dimethyl polysiloxane or other silicone fluid with a viscosity of 30,000 to 5 million centistokes. The shear resistance of the fluid increases linearly at lower shear stresses and less than linearly at higher shear stresses. Because the narrow gap is at a large radius, high shear stresses are developed there, with apparent decrease in viscosity of the fluid. The net effect is that the shear resistance of the damper increases less than linearly with angular velocity of the surfaces.

Title: Continuous production of industrial starch pastes
Inventor: HUBER KENNETH J
IPC: C08B30/16
Filed: 1965-11-08
Abstract: <PICT:1090550/C3/1> Starch paste is made by continuously feeding a stream of aqueous starch slurry containing at least 0.5 lb./gal. of starch to a steam injection heater wherein the slurry is pasted by heating with steam at 60-140 p.s.i.g., continuously introducing the heated paste to a pressure converting zone wherein it is cooked at 250-350 DEG  F., and feeding the converted paste into a vessel at atmospheric pressure.  Steam and other gases may be separated from the paste after the pressure on it has been reduced to atmospheric, and the paste may be diluted with water while such separation is taking place. Starch slurry containing e.g. 0.5-3.0 lb./gal. of starch, is fed from tank 1 via pump 3 and valve 9 to steam-injection heater 5 supplied with steam from 7.  The resulting paste is fed to heat-insulated pressure-cooking vessel 13 provided with baffle 12 to provide a continuous path for the paste without channelling, and with valve 20 for outlet of non-combustible gases.  The converted paste flashes atmospheric pressure via valve 18 into centrifugal separator 22, from which gases can be removed via vent 23, and into which diluting water can be fed through line 26.  The level of paste in vessel 13 is regulated by device 16 which senses the pressure differential between gas at the top of the vessel and the hydraulic pressure in line 15, and automatically adjusts the opening of valve 18.

Abstract: 1485997 Winches BARWIN PTY Ltd 8 Nov 1974 [12 Nov 1973] 48435/74 Heading B8B [Also in Division F2] A manually operable winch comprises a winch drum 7 rotatable in a clockwise direction at various gear ratios depending on the direction of rotation of an operating handle 10 and the position of a gear selector control plate 16. Upon the latter being rotated into its clockwise position relative to the drum, a first gear ratio is selected whereby clockwise rotation of the handle produces equal speed of the drum, and anti-clockwise rotation of the handle causes the drum to continue clockwise rotation at an intermediate lower speed relative to the handle, this anti-clockwise rotation of the handle causing the plate 16 to be urged into its anti-clockwise position to select a second gear ratio which becomes effective when the handle is next rotated clockwise. With clockwise rotation of the handle, the second gear ratio produces the lowest drum speed relative to the handle, the said intermediate lower speed being obtained if the handle is again rotated anti-clockwise. The handle 10 is splined at 12 to a drum shaft 9 which is splined at 22, 23 to a ratchet ring 21, the latter engaging pawls 24, 25 hinged to the drum 7 when the handle is rotated clockwise and the plate 16 is in the first gear position which is a clockwise limit position of the plate 16 relative to studs 17, 18 mounted on the drum and extending through arcuate slots 19, 20 in the plate 16. Anti-clockwise rotation of the handle 10 causes the ring 21 to override the pawls and the drum is driven via reduction gearing 13, 14, 15. During anti-clockwise rotation of the ring 21, it is axially moved towards the control plate 16 by interengaging cams 33 on the ring 21 and cams 37 on a plate 34, whereby spring loaded balls 36 on the ring 21 engage recesses 35 on the plate 16 to move the latter into its second gear, anticlockwise position relative to the studs 17, 18 where it is spring biased away from the drum and prevents re-engagement of the pawls 24, 25 with the ring 21 when the handle 10 is subsequently rotated clockwise again, to facilitate drum driving through the lowest gear of the gearing 13, 14, 15.
