Title: Improvements in the manufacture and production of valuable coloured compounds
IPC: C09B69/06
Filed: 1927-06-21
Abstract: 275,943. I. G. Farbenindustrie Akt.- Ges. Aug. 12, 1926, [Convention date]. Samples furnished. Lakes.-Coloured compounds which may be used as pigments are obtained by treating primary, secondary or tertiary aromatic amines, which are not basic dyestuffs and are free from acid groups, with complex acids containing tungsten or molybdenum, or their salts, or with substances capable of forming such complex acids, the said substances being used simultaneously or in succession. Phosphotungstic, phosphomolybdic, phosphotungstomolybdic and silicomolybdic acids are specified ; the process may be carried out at ordinary or increased pressures. The products may also be subjected to an aftertreatment under pressure and at an elevated temperature and preferably with the addition of salts, especially of such complex-formers which are not present, or are present in insufficient amount, in the complex compounds. When compounds capable of forming complex tungsten compounds are used, the process is preferably carried out in the presence of acids having a dissociation constant exceeding that of tartaric acid. The compounds may be formed in the presence of substrata, e.g. heavy spar or blanc fixe; dispersing agents, e.g. turkey red oils, soaps, saponines, cholates, glue, tragacanth, cellulose esters or ethers, or mixtures of these may also be used to cause precipitation in a finely-divided state. When the process is carried out in the presence of acids, the initial products are often colourless or only slightly coloured, but they may be converted into brightly coloured products by warming or by neutralizing the free acid. In examples, (1) 4 : 4<1>-tetramethyldiaminodiphenylmethane is dissolved in concentrated hydrochloric acid and treated with sodium phosphotungstomolybdate; a deep blue product is obtained on neutralizing with sodium carbonate: (2) 4 :4<1>-tetramethyldiaminobenzhydrol is similarly treated with sodium phosphotungstomolybdate to give a deep bluish-violet compound; (3) 4: 4<1>-tetramethyldiaminobenzophenone is dissolved in sulphuric acid and treated with sodium phosphotungstomolybdate, the acid is neutralized with caustic soda solution, and the reaction mixture is warmed with sodium carbonate, an orange-brown precipitate is obtained; (4) paminobenzaldehyde is dissolved in dilute hydrochloric acid and mixed with sodium phosphotungstomolybdate; a red-orange precipitate is formed, which changes to orange on neutralization with sodium or barium carbonate.

IPC: E21B19/087
Filed: 1955-06-10
Abstract: 834,214. Feeding rock drills. HARDYPICK Ltd. June 8, 1956 [June 10, 1955], No. 16791/55. Class 124. An extendable feed leg for a rock drill having inner and outer telescoping members, the inner member carrying the drill on one end, the other end acting as a piston under the action of an hydraulic fluid, has a reservoir for hydraulic fluid supported by the inner member, the reservoir forming part of a closed circuit including a pump operated by the drill. As shown, the feed leg comprises a hollow outer member 10 having ground engaging means 12, 24 at one end, and a hollow inner member 11 carrying a drill 14 at its outer end which extends beyond the outer member, the other end of the inner member being within the outer member 10 and forming a piston head having a hole therethrough. Hydraulic fluid may be held in a reservoir 16, mounted on the inner member and having a bellows 18 open on one side to the atmosphere fitted to one end, and may be drawn therefrom through a pipe 20 by means of a pump 15 mounted on the drill and recirculated through a pipe 21. A three-way cock 22 in the pipe 21 may be manipulated to discharge the fluid through the hollow inner member 11 where it acts on the piston to extend the leg. The leg may be collapsed by shutting off the pump and manipulating the cock 22 so that the hydraulic fluid passes from the inner member into the reservoir 16. The drill and pump may be controlled by twist-grip handles 23.
Patent GB-1086219-A (GB)
Title: Improvements in or relating to the cutting of reinforced glass
IPC: C03B33/07
Filed: 1965-04-21
Abstract: <PICT:1086219/C1/1> <PICT:1086219/C1/2> A method of breaking the metal meshwork of a travelling ribbon of reinforced glass to separate from the ribbon a strip along a line along which the glass has previously been scored and broken, comprises causing the strip to move gradually in a direction out of the plane of movement of the ribbon while maintaining the ribbon in its plane of movement, until the meshwork breaks.  A ribbon of wired glass 1, previously scored to form strips along both edges, is continuously advanced on a roller conveyer 50 into a breaking apparatus.  The undersurface of the ribbon passes over two rollers 2, 3 whilst the upper surface of a side strip passes under a roller 8, these rollers co-acting to break the glass strip along the score line but not breaking the metal meshwork.  As the ribbon advances, the strip 12 contacts an upwardly-sloping ramp 23, the top surface of which also slopes sideways downwardly.  The ramp 23 co-operates with rollers 24, 25 which act on the upper face of the strip to break the metal meshwork, whilst rollers 26, 27, 28 maintain the ribbon in its plane of motion. The thus severed strip then passes under a further roller 45 which guides the strip downwardly away from the ribbon into a waste hopper. The rollers and the ramp are all mounted in a framework 13, 14, 15, 151 suspended upon rails 16, 161 which permits movement to cope with ribbons of different width.  The individual rollers are all vertically and horizontally adjustable.

Title: Arithmetic units
IPC: G06F7/493
Filed: 1976-04-26
Abstract: 1531919 Arithmetic units INTERNATIONAL BUSINESS MACHINES CORP 26 April 1976 [2 June 1975] 16809/76 Heading G4A Additional circuitry is provided with a radix r arithmetic unit adder to detect the condition "all zeros" or all "sum digits radix less one" (SDRLO) as early as possible using the expression where (K)z signifies that the normalized sum of the Kth digits of a pair of operands is Z, K taking values 0 to (n-1) high order to low order. The above expressions (1) and (2) are derived by combining a pair of conditions such as and iteratively combining the result with another condition until all conditions have been dealt with. The circuitry may be implemented by a combination of NAND and AND-DOT logic, Figs. 15, 16 (not shown). Fig. 14 illustrates a single digit position for a BCD arithmetic unit and derives, for each pair of bits A 8 , B 8  to A 1 , B 1  the carry generate function Gi=Ai. Bi and the carry propagate function Pi=Ai+Bi. The functions G and P are then combined in NAND-AND DOT logic to produce sum values (K) 18 , (K) 10 , (K) 9 , (K) 8  and (K) 0  for input to the zeros and SDRLO detection logic. The G and P functions can also be combined to generate (K)# 10 , (K)# 9  values for input to the carry look-ahead circuits of the adder. For a binary arithmetic unit implementation of the detection circuitry is possible using the half sum function Hk=Ak#Bk as well as functions Gk and Pk. By combining the expressions for the all zeros condition, i.e. in the manner in which expressions (1) and (2) are derived, and similarly Circuitry for implementing these expressions is illustrated in Figs. 3 and 6 (not shown). Still further simplification is possible if the carry out (Cout) or an intermediate carry Ck is utilized, though at the expense of increased time delay since it is necessary to wait for generation of the carry before ZEROS or ONES can be generated. The expressions for ZEROS and ONES are as follows:- using Cout-Figs. 4 and 7 (not shown), and using the intermediate carry C k -Figs. 5 and 8 (not shown).
