Title: Improvements in or relating to the manufacture of titanium pigments
IPC: C01G23/08
Filed: 1930-12-31
Abstract: A calcined titanium oxide of increased covering power and reduced oil-absorption is obtained by mixing certain accelerators with a titanium compound precipitated by hydrolysis, and calcining the mixture at about 900 DEG  C. or under.  The titanium precipitate may be a hydrated oxide, meta- or orthotitanic acid, or a basic sulphate obtained by hydrolysis from a sulphate solution, and it may be precipitated on or mixed with an inert pigment.  The accelerator is the hydrate, sulphate, nitrate, or carbonate of sodium or potassium, or the sulphate of aluminium or magnesium, in quantity not more than 10 per cent of the titanium oxides.  The accelerator is preferably added in solution to the precipitated titanium pulp; it may be formed in situ during the precipitation.  The calcining temperature is generally 850-900 DEG  C. The calcined product may be washed and dried before milling, or it may be treated by wet milling, to remove any part of the accelerator which remains soluble.  In examples, the accelerator used is 0,25, 0,5, or 1,0 per cent of sodium sulphate, or 1 per cent of sodium nitrate, and in another example, 0,5 per cent of sodium sulphite is used with a pigment consisting of 3 parts titanium oxide and 1 part barium sulphate.

Abstract: 1,179,577. Making electromagnetic coils; rolling. BRITISH INSULATED CALLENDERS' CABLES Ltd. 28 Aug., 1968 [29 Aug., 1967], No. 39470/67. Headings B3A and B3M. [Also in Division H1] Transformer windings or other electromagnetic coils are made by profiling the longitudinal edges of a metal strip, applying and semi-curing a coating of a thermosetting resin on the entire surface of the strip, winding the coated strip with a separating layer of sheet insulating material, which is permeable to the semi-cured resin when in a molten state, to form a convolute coil and subjecting the coil to heat and vacuum to dry the insulating material, impregnate it with the resin and to complete the cure of the resin and bond together the convolutions of the coil. Alternatively, the sheet insulating material may be impregnated with semi-cured resin prior to winding in which case the coating, which may be of cured resin or other insulating material, on the strip may be reduced in thickness or omitted altogether. The preferred insulating material is paper and the preferred resin an epoxy or an acrylic resin. If desired, a number of metal strips and insulating sheets may be interleaved and wound together to form a number of coaxial coils. Rolling.-The profiling is carried out by means of a series of pairs of profiling heads 3, 4 mounted in two sets between support rolls 1 carrying the metal strip 2. Each head comprises a set of four cylindrical rolls in two pairs adjacent each other, only one pair 5, 6 being shown and the rolls of each pair being mounted with their axes perpendicular to each other and to the longitudinal edge of the strip. The axis of roll 6 is at an angle a to the plane of the strip and this angle is different for each pair of profiling heads. When three sets of profiling heads are used the respective values of α are 10, 45 and 80 degrees to give each edge of the strip a semi-polygonal form.

Title: Improvements in or relating to an apparatus for measuring hardness
IPC: G01N3/44
Filed: 1961-11-09
Abstract: 970,309. Hardness impact testing. A. ERNST. Nov. 9, 1961 [Nov. 9, 1960; Oct. 11, 1961], No. 40203/61. Heading G1S. In hardness-testing apparatus giving pre-load and main load of a penetrating member 1 in a single operating movement, the holder 2 for the tip 1 has a resilient portion 29<SP>1</SP> at its widened upper end for frictional engagement with a slider 3 integral with washers 17, 18 (to limit movement of the slider in co-operation with locking rings 19, 20) and a feeler 4 The latter bears against a disc 5 on a diaphragm 6 closing a fluid chamber communicating with a capillary indicating tube 9. The diaphragm-fluid chamber assembly (5-15) rests on a cylindrical body 23 narrowed at 24 and terminating in hood 44. Initially, the whole apparatus is held in the fully-raised position by spring 31, resting on a ring 25 engaged with the base 26, and acting on the casing 30. A pin 49 secured to a part 48 carried by pillars 56 extending (through suitable apertures) from ring 25, bears against the part 29 of the holder 2 to cause the tip 1 to protrude beyond hood 44 by a predetermined amount. As casing 30 (and thereby -the whole apparatus) is lowered using handles 46, the tip 1 engages the surface of the work-piece under a driving pressure due solely, in the first instance, to the frictional force on the part 29<SP>1</SP> as the slider 3 moves downwards. During this initial movement, the feeler 4 (and slider 3) rests on a cross-piece 16 supported on a sleeve 35. When hood 44 makes contact with the surface, the cylindrical body 23 is arrested and with it the diaphragm-fluid chamber assembly. Deflection of the diaphragm 6 is then maintained only by the frictional force between the part 29<SP>1</SP> and slider 3 since cross-piece 16 now falls with further lowering of the casing 30 and sleeve 35. Screws 36 in the latter constrain upwardly a second cylindrical body 37 having a cross-piece 40 against spring 38. After casing 30 has been lowered sufficiently, the cross-piece 40 will engage pin 41, which is rigid with the holder 2, to subject tip 1 to the full pressure of spring 38 as the screws 36 break engagement with the upper edges of the apertures in the cylindrical body 37. As holder 2 descends with further penetration of the tip 1 under' the increased load, the part 29<SP>1</SP> will take with it, by friction, the slider 3 to give a decreased deflection of the diaphragm observable in the capillary tube 9. In a modification of the apparatus, the feeler 4 is in the form of a ball, slider 3 is elongated to give a large bearing surface, and friction is provided by a clip the pressure of which is adjustable.

Abstract: 1,199,867. Cutting apparatus. EASTMAN KODAK CO. 23 Aug., 1968 [23 Aug., 1967], No. 40350/68. Heading B4B. A severing device for strip or sheet material fed from a supply comprises a fixed knife 15 and a pivoted knife 16 normally held in the open position shown in Fig. 2 against the action of a spring 24 by means of a latch member 29 so that a strip 23 of material can pass between the knives, and a support plate 42 for the supply of material adapted to be moved away from the knives in order to effect the release of the latch member. The latch member 29 is connected to an arm 36 which is provided with a slot 44 through which passes a pin 43 attached to the support 42. In order to sever the strip material, the support 42 is moved to the right as viewed in Fig. 1 until the pin 43 abuts a shoulder 46 in the arm 36 thereby moving the latter to release the latch 29; continued movement of the support causes a cam surface 40 on the arm 36 to engage with a fixed pin 47 thereby allowing the arm 36 to return and so reset the latch. The knife 16 is re-cocked to the position shown in Fig. 2, by means of a lever 53.
