Oxide bodies are made by dewatering a hydrous oxide sol to form a gel, heating the gel to decompose it to the oxide but not to sinter it, forming the oxide into a green body and sintering the green body at 1700-1900‹ C. Suitable sols are those of the oxides of thorium, cerium, titanium, hafnium, zirconium and aluminium and are stabilized by adding a solution of a thermally decomposable salt of magnesium, calcium or yttrium to the oxide sol. A solution of yttrium nitrate is added to a sol containing 500 gm. of colloidal thoria per litre of water to incorporate 5-15 mole per cent of yttria in the product. Water is removed by heating at 100‹ C. and the glassy gel formed is decomposed at 950‹ C. The oxide formed is ball-milled in carbon tetrachloride and the milled powder dried at 50‹ C. and formed into a tube by isostatic pressing at 30,000 lbs per square inch. The formed tube is sintered at 1700‹ C. for 2 hours, fully oxidized in air at 1400‹ C. for 4 hours and then reduced by heating at 1000‹ C. for 4 hours in hydrogen saturated with water vapour at room temperature. When alumina is used the alumina gel is decomposed by heating at 1100‹ C.

Title: Load transfer
IPC: B63B27/00
Filed: 1976-02-28
Abstract: 1524314 Indicators associated with winches FERRANTI Ltd 24 Feb 1977 [28 Feb 1976] 07939/76 Heading B8B An indicator for indicating conditions suitable for lifting a load from a first of two stations movable vertically relative to each other is used so that the velocity of the load being lifted can exceed the vertical velocity of approach of the two stations, created when one station is slowing down, is stationary, or is moving away from the other station. The indicator comprises winding means for sensing relative movement between the stations to produce signals representative of relative velocities and accelerations of the stations and means responsive to the magnitude and/or sense of the signals to provide an indication signal when the relative velocity of approach of the stations is between a maximum positive value and a negative value and the relative acceleration of the stations is in a direction away from the direction of approach. The actual velocity and acceleration valve signals are fed to comparators 11, 13 for comparison with threshold values and a velocity output signal from the comparator 11 only occurs when the actual velocity is below the threshold value, and an acceleration output signal from the comparator 13 only occurs when the actual acceleration is acting away from the direction of approach of the stations. The signals are then sent to a signal latch 21 through a time delay circuit which prevents rapid variation action.

Title: Improvements in lasting machines
IPC: A43D21/16
Filed: 1927-03-25
Abstract: 268,769. Maschinenfabrik Moenus Akt.-Ges. March 30, 1926, [Convention date]. Lasting and pulling-over. - Relates to handmethod lasting machines, wherein instead of the pincers opening during the operative stroke of the wiper, their grip of the upper is maintained but reduced, so that the upper gradually slips from the pincers during the operative stroke of the wiper, and consists in the provision of an automatic pawl and step mechanism for maintaining this reduced grip. The pincers are of known form comprising a casing 2 carrying the lower jaw 1, and an upper jaw 7 guided by links 5, 9 and cams 11, 12 kept in contact by a spring- pressed plunger, and a gripper opening and closing rod 3 slidable in the casing and normally held in raised position, with the pincers open by a spring 16. The rod 3 is depressed, to close the grippers on the upper, by the usual plunger 21 backed by an adjustable spring 23 carried on an arm 25 fixed to a shaft 26 operated by an arm 28 provided with a roll co-operating with a cam 31 on the main shaft of the machine. Pivoted on the shaft 26 is an arm 34, the free end of which is depressed by a spring 39 the tension of which may be adjusted by a wing nut 42. To the arm 34 a lever 44 is pivoted at 35. To one end of this lever is bolted a pawl 47, which normally engages a step 48 secured to the arm 25. The other end of the lever 44 has pin and slot engagement with a rod 58 adjustable in length and pivoted to a member 52 which swings about a pivot 51 to actuate, in the usual manner, the lateral movement and twist of the grippers. The lever 44 also carries an eccentric adapted to engage the arm 34, and operated by a handle 64. In operation, at the point in the cycle where the cam 31 ceases to depress the plunger 3 through the medium of the spring 23, the arm 25 is prevented from rising, under the thrust of the spring 16, by the pawl 47, which is maintained depressed by the spring 39. This spring is so much weaker than the spring 23 that the upper margin gradually slips from the pincers as the wiper advances in its operative movement. At a point determined by the adjustment of the length of the rod 58, preferably as the usual tack is driven, the lever 44 is operated to free the pawl 47 and allow the pincers to open. When the machine is desired to function in the usual manner, the pawl 47 is put out of action by the handle 64.
