Title: Phosphate compositions, their production and use
IPC: C11D3/48
Filed: 1955-04-18
Abstract: A phosphate composition, suitable for incorporation in detergent compositions, comprises an anhydrous alkali-metal phosphate having a molar ratio M2O/P2O5 of 5/3-2/1, preferably anhydrous sodium tripolyphosphate and/or anhydrous tetrasodium pyrophosphate, and a water-soluble linear polymeric phosphate having more than 3, and desirably more than 10, phosphorus atoms in a linear chain, the proportion of this polymeric phosphate, which is preferably an alkali metal or ammonium salt, not exceeding 10 per cent, and preferably not exceeding 1 per cent, of the total dry weight of mixed phosphates. When the anhydrous alkali metal phosphate is sodium tripolyphosphate, more than 75 per cent of the tripolyphosphate should be in the low temperature form, Form II.  The compositions may be prepared by grinding or comminuting the ingredients together; by forming a solution of the polymeric phosphate in a volatile solvent such as water or an alcohol-water mixture and then spraying the solution on to a heated bed of the anhydrous phosphate; or by exposing an alkali metal tripolyphosphate to an elevated temperature for a relatively short period followed by rapid cooling, in order to form a surface of fused polymeric phosphate on the surface of the tripolyphosphate. Compositions prepared as described are said to exhibit a decreased loss of fluidity due to crystallization when incorporated in detergent slurries which are to be spray-dried.

Title: Improvements in and relating to the manufacture of refractory bricks, slabs and the like
IPC: C04B35/057
Filed: 1935-04-10
Abstract: A process for manufacturing refractory lime bricks, slabs, &c consists in moulding, under high pressure and without the use of a binder, a finely divided mixture of calcined lime and an oxide of iron, chromium or aluminium, and burning the moulded mixture.  The amount of oxide in the mixture is generally from ,5 to 5 per cent. The ingredients are in a state of subdivision fine enough to pass a sieve having from 6,000 to 20,000 meshes per sq. cm. The moulding pressure is from 300 to 1000 or more kgs. per sq. cm. and the burning temperature is suitably from 1350 to 1500 DEG  C.  A certain amount of the finished product in a granular state may be added to the finely powdered mixture before the pressing step, e.g. 70-80 parts of granular material to 30-20 parts of powder.

Abstract: 711,411. Grinding internal surfaces. BRYANT CHUCKING GRINDER CO. May 2, 1952 [May 19, 1951], No. 11161/52. Class 60 [Also in Group XXX] Raceways 20, Fig. 4, for ball bearings are rotated by members 15 and 25 between which they are clamped while their internal surfaces are ground by a tool 42, the thrust from which is taken by supports 60, Fig. 2. The clamping pressure is produced by a spring 6, Fig. 1, interposed between a flange 7 on a spindle 3 and a shoulder 5 on a shaft 4 connected by a pipe 21 with the member 15. The latter is slidably mounted in a guide member 10 secured to the forward end of the spindle 3 and has its movement towards the member 25 limited by a stop 8. A flexible pipe connected to a nipple 22 supplies coolant through the shaft 4 and pipe 21 to the raceways 20. The spindle 3 is rotated by a belt driven pulley 9 while the member 25 may be rotated by a jet of air directed by a nozzle 51 on to vanes 50 or by a jack shaft and belt drives from a second pulley on the spindle 3. The supports 60 have concave faces on rollers to engage the raceways and are adjusted to hold the latter in slightly eccentric relation to the member 15 by adjustment of screws 67. During grinding, the raceways are held against the supports 60 by rollers 70 mounted in yieldable bushings 70b on an arm 71 to which one or more ejecting fingers 78 are also secured to push the raceways into a discharge shoot 79 when the arm is turned about a pivot 72 by means 75 at the end of the grinding operation. The raceways are fed to the machine by a separator 80 which is oscillated in timed relation to the other parts of the machine and has two fingers 82 and 83 positioned to separate and deliver a batch of the desired number of raceways on each oscillation.

Abstract: 580,217. Vehicle blinds. WILMOT-BREEDEN, Ltd., and SPICER, H. J. June 19, 1944, Nos. 11646 and [23944. [Class 20 (iii)] In means for operating window blinds of vehicles a lazy-tongs linkage is attached to the blind and operated by a screw or worm rotated by a reversible electric motor the circuits of which are automatically controlled by the operating means. As shown in Fig. 1, to the blinda is attached a lazy-tongs linkage b with an additional link d to prevent tilting of the blind. The other ends of the lazy-tongs are attached to nuts f on a right and left hand screw e rotated by a reversible electric motor (not shown), and when the blind reaches either limit one of the nuts f contacts an end k of a trip piece j which automatically switches off the motor by a projection m actuating a two-way tumbler switch n, the motor being restarted in the opposite direction by a complementary twoway hand switch. As shown in Fig. 2, the ends of the lazy-tongs are pivoted to oscillatory arms o, pivotally supported in a housing p open at the top and having a flexible dust-protecting covering x. The other ends of the arms o are formed so as to intermesh with a worm h connected through reduction gearing to the motor s, and on one of the arms is mounted a two-way switch t with an actuating lever u, which is reversed by a stop v when the blind reaches either limit. One of the stops v may be adjustable as at w. In a further modification, the worm h is connected to the motor s by a flexible belt passing over pulleys, and the motor is automatically switched off by parts of one of the arms o contacting one of two fixed switches, one of which may be adjustably mounted.

[Class 108 (ii).] In motor vehicles in which the front wheels are guided parallel to one another and to the central vertical plane of the body and in which the independently sprung rear wheels oscillate around a central longitudinal axis so that the axis for the transverse oscillations of the vehicle is a straight line rising obliquely towards the rear, the centres of gravity of the vehicle, of the driving unit and of the principal masses are grouped as near as possible to the axis of oscillation so as to reduce their effective leverage about such axis and so reduce to a minimum such oscillations. As shown, the central tube frame member a is disposed lower than the wheel axles and is connected at the rear to the driving unit c, d, e. The front wheels, mounted on transverse springs b1, b2, oscillate about a point A while the rear wheels carried by half axles f1, f2 sprung from the transverse beam i oscillate about a point B so that the axis of oscillation of the whole vehicle is one rising obliquely to the rear and the masses of the frame and body on the one hand and the driving unit on the other are so arranged as to give centres of gravity s1, s2 respectively close to such axis of oscillation resulting in the centre of gravity s of the whole vehicle being also close to such axis.
