Filed: 1930-11-28
Abstract: A glyptal resin suitable for adding to a rubber mix to prevent scorching is made by mixing 148 parts by weight of phthalic anhydride with 62 parts of glycerol at 175 DEG  C.  Water is evolved and the mixture thickens, and when the acid value has been reduced to 150 the reaction is stopped.ALSO:Rubber mixes are prevented from scorching during milling operations by the incorporation into the mix of an acid polyhydric-alcohol-polybasic aromatic acid condensation product, preferably having an acid value of 100-150, such as the product of reaction of glycerol and phthalic acid (or anhydride).  The resin may contain other radicals such as those of the fatty acids.  A typical resin is prepared by heating 148 parts by weight of phthalic anhydride with 62 parts of glycerol at 175 DEG  C.  Water is evolved, the mixture thickens and when the acid value has been reduced to 150 the reaction is stopped.  Tests on a recovery plastometer are quoted to demonstrate the effects of the addition of the above compounds. Specification 316,932, [Class 70, Indiarubber &c.], is referred to.

Abstract: 1,153,478. Extruding asbestos fibres. REX ASBESTWERKE GRAF VON REX K.G. 23 Aug., 1966 [23 Aug., 1965], No. 36082/65. Heading B5A. [Also in Division D1] In the production of a strand composed wholly or predominantly of asbestos by passing an aqueous dispersion of asbestos fibres through an orifice into a liquid which forms the dispersion into a coherent strand as described in Specification 824,446, the action of the liquid is increased by stretching the strand and/or subjecting it to pressure. The strand may be stretched by feeding the liquid past it at a speed higher than the speed of the strand, the speed of the liquid being then reduced by passing it into a conduit of larger cross-section, or by removing some of the liquid, by passing the strand through one or two pairs of nip rolls, or by passing the strand around a capstan and then through a pair of nip rolls or around a second capstan. The strand may be subjected to pressure by passing it and the liquid upwardly into a chamber in which the strand forms superimposed coils. The aqueous dispersion may contain sodium soap and an anionic surface-active agent, and the liquid may be a solution of aluminium, magnesium or zinc sulphate. Alternatively the asbestos may be changed from a dispersed to a coherent state by changing the pH of the dispersion.

Title: Improvements in process for halogenation of materials
IPC: C01G1/06
Filed: 1937-12-31
Abstract: 510,438. Halogenating materials ; retorts for making chemical compounds. FINK, C. G. Dec. 31, 1937, No. 36242. [Classes 1 (i) and 1 (iii)] [Also in Group IV] In a process for halogenating materials at elevated temperatures with gaseous reagents, such as chlorine, phosgene, bromine, or fluorine, the reaction chamber is formed of or has a lining of a metal which reacts with the halogen at relatively low temperatures, but not at operating temperatures and the reaction chamber is heated above said temperatures before introducing the halogenating gas. By these means. attack of the metal comprising the reaction chamber is avoided. In an example relating to the chlorination of beryl, an electrically heated shaft A of nickel is lined with gold in the part X where reaction is effected at 900‹C., the part Y of the shaft which serves for preheating chlorine introduced at K being heated to 500‹C. Beryl is supplied at G, gangue is removed at M, and beryllium and aluminium chlorides are volatilized and pass off at I and are separated by fractional condensation. The chlorine used may be replaced by fluorine, but when using bromine carbon is mixed with the ore and the reaction occurs at 450‹C. Reference is made also to the use of platinum and tungsten as suitable metals for the construction of the reaction chamber, to the chlorination of methane for the production of carbon tetrachloride, and the chlorination of natural gas containing ethane for the formation of hexachlorethane.

Title: Improvements in or relating to bistable circuits
IPC: H03K3/286
Filed: 1963-09-16
Abstract: 976,694. Electronic counters. SPERRY RAND CORPORATION. Sept. 16, 1963 [Sept. 27, 1962], No. 36368/63. Heading G4A. [Also in Division H3] Bi-stable circuits in a binary counter comprise NOR circuits arranged substantially as shown to form the basic bi-stable circuit 10, 12 enclosed within the upper dotted rectangle and the steering circuit shown in the lower dotted rectangle, whereby two triggering pulses at the imput are required to effect a cycle of set and reset of the basic circuit. Assuming the NOR 12 output is at 0 and the input is at "1", the output of 18 and 20 are "0" and the output of 32 is "0". The output of 10 will also be a "1" so that the output of 30 is at 0. If the input signal now returns to "0", the output of 18 becomes "1" which holds 20 and 30 at "0" condition and also changes over the bi-stable circuit 10, 12 so that 32 changes to a "1". The return to the "1" condition of the input signal causes 18 to produce "0" so that 30 produces a "1". The circuit is now such that when the input signal becomes "0" the bistable circuit returns to its original state. The NOR circuit may be of the diode-transistor type (Fig. 3a not shown) and the bi-stable circuits are arranged in succession as at 00 and 01 to form a counter.

Abstract: 1477555 Coupling implements to tractors JEAN WALTERSCHEID GmbH 4 Sept 1975 [7 Sept 1974] 36419/75 Heading A1P A coupling for connecting a vehicle such as a tractor with an implement, which may be used in addition to three point linkage, is characterised in that locking means 33, 12, keeping pivoted retaining pawls 1, 20 engaged on locking shafts 35, 16, have an actuating member 29 for releasing the locking means from its locking condition and a blocking member 7 preventing such release of the locking means, the blocking member and the actuating member both being required to be operated before release of the coupling can be effected. The retaining pawls are mounted on each of two catch arms 36 which are rigidly connected by a catch plate 5 and pivotally mounted at their lower ends on a bearing shaft 18 connected to the tractor. The upper retaining pawl engages on the locking shaft 35 provided on the tractor and the lower retaining pawl 20 engages on the locking shaft 16 provided on a shield plate attached to the implement. The retaining pawls are connected by springs 4, 50 with the blocking member 7 and with the locking means 12, resepectively the blocking member being pivotally connected with the locking means 33. The actuating member 29 is connected to a safety linkage 31 Operable from the driver's cab and the blocking member is operated by a pivoted power lever 8 connected to the hydraulic lifting system of the tractor. The catch arms 36 are provided with a catch cradle 41 for engagement with a complementary structure provided on the shield plate of the implement. Setting the hydraulic system to "lift", pivots the power lever 8 causing a projection 9 to act on a curved surface 27 of the blocking member to release the blocking member from engagement with a stop 25. The safety linkage can now be operated causing the locking means 33 to be moved away from the retaining pawl 1. The connected blocking member 7 moves downwardly to act on a lock release cam 23 provided on the locking means 12 to move the locking means 12 away from the retaining pawl 20. This movement of the locking means 33, 12 causes the springs 4, 50 to be tensioned which, in turn, causes the retaining pawls to be pivoted to the position shown in Fig. 2, releasing the locking shafts 35, 16. The hydraulic cam can be switched to "drop" causing the whole assembly to pivot about the shaft 18 and allowing the implement to be detached. Due to the springs 4, 50, attachment of a different implement automatically sets the retaining pawls, locking means and blocking member into their coupled and locked positions.
