Abstract: 1,194,050. Stabilized polyisocyanate compositions. IMPERIAL CHEMICAL INDUSTRIES Ltd. 28 Oct., 1968 [12 Dec., 1967], No. 56498/67. Heading C2C. Polyisocyanate compositions comprising a diphenylmethane diisocyanate in which from 1% to 50% of the isocyanate groups have been reacted with a non-sterically hindered aromatic carbodiimide other than a carbodiimide derived from diphenylmethane diisocyanate are obtained by mixing the diisocyanate and the carbodiimide and allowing the compounds to react. The reaction is suitably effected at a temperature of 40-150 C., optionally in the presence of a solvent. The sterically hindered aromatic carbodiimides employed are those in which the aromatic rings are free from substituents in the ortho positions adjacent to the carbodiimide group. A suitable class of carbodiimides are those of the formula wherein R<SP>1</SP>-R<SP>6</SP> are hydrogen, hydrocarbon, hydrocarbyloxy, halogen, nitro, carboxyester, isocyanate or substituted hydrocarbon groups; other diimides are, however, specified. The resulting compositions probably contain uretonimines formed by addition of an isocyanate group to one of the double bonds of the carbodiimide. Specific examples describe the reaction of 4:4<SP>1</SP>-diisocyanatodiphenyl methane (containing a small proportion of the 2:4<SP>1</SP>-isomer) with (i) di-p-tolyl carbodiimide, (ii) diphenyl carbodiimide, and (iii) di-p-chlorophenyl carbodiimide.

Abstract: 1,218,747. Automatic pipette. XEROX CORP. 15 Dec., 1967 [15 Dec, 1966], No. 56985/67. Heading B1X. An automatic pipette 64, e.g. of polyethylene, is mounted on head 220, and is oscillated between sample carrying tape 24 and analytical tape 14 by means of gearing driven by motor 240, which also governs the movement of sprocket driven tapes 14 and 24. Samples are deposited on the appropriate positions on tape 24 determined by indicator (26) (see Figs. 2 and 3, not shown), and eventually pass to a point at which pipette 64 is lowered into the sample by means of depressor 264 actuated by solenoid 258 which causes the head 220 to drop. Suction is then applied through means not shown to cause a predetermined amount of sample filling pipette 64 to be taken up; when an excess is taken up, the first drop from the end of the pipette mounted in head 220 passes between light 254 and photocell 256, causing solenoid 258 and its associated mechanism to lift head 220. Head 220 is then swung so that pipette 64 is positioned over reaction site 272 on tape 14, any excess sample on the outside of the pipette being removed by absorbent tape 270 against which pipette 64 brushes in the course of its travel. When positioned over site 272, pressure is applied by means not shown in head 220 so as to eject the sample from pipette 64 on to site 272. Head 220 is then swung back to its position over tape 24 and the cycle repeated as the tapes 14 and 24 are advanced. Analytical tape 14 then passes to incubator (18) (see Figs. 2 and 3, not shown) where the reaction is developed, and then to detector (20), e.g. a photocell. If desired, tapes 14 and 24 may be driven by separate motors so that several portions of the same sample may be delivered to a plurality of reaction sites on tape 14.

Patent GB-644091-A (GB)
Abstract: 644,091. Cash registers. NATIONAL CASH REGISTER CO. Dec. 23, 1947, No. 33979. Convention date, Sept. 8, 1944. [Class 106 (i)] In a cash register including members set under the control of item-entering keys, a locking device for locking said members after they have been set, and further members controlled by said first members to set indicators and type carriers, there is provided for each denomination, a first beam connected to the first member and articulated to a second beam connected to the further member, a fixed stop and a device oscillated at each machine operation to move the beams into coincident relationship against the fixed stop. When arms 22, Fig. 1, carrying a rod 21, are rocked counter-clockwise, a differential actuator 10 in each denomination is rocked about a shaft 11 by a spring 18 until an abutment 17 engages the stem of the depressed key 12. A flange 25 or other projection on a control segment 24 is held against the actuator by a spring 125 so that the segment is also differentially positioned, after which positioning a locking bar 41 engages one of a set of locking teeth 39 on the segment. An arm 27 is pivoted on the segment and carries a roller 28 running in a slot in a second arm 30 pivoted on a toothed segment 32 geared to an indicator drum 34 and through a sleeve 37 to a type-wheel. Arms 44, carrying a rod 45, are then rocked clockwise so that the rod, by forcing the arms 27, 30 against a collar on the shaft 11, causes the toothed segment 32 to assume a position corresponding with that of the control segment 24. The toothed segment, and the indicator drum and type-wheel set thereby, may thus be moved slowly and, once the control segment has been locked, the actuator 10 may be restored by the bar 21 to enter the amount into one or more selected totalizers 23. When the toothed segment 32 has been positioned, the locking bar releases the control segment 24 to the action of the now tensioned spring 125 and engages locking teeth 40 in the toothed segment to prevent further movement until during the next machine operation. In a machine having a flat keyboard, Fig. 2, a rod 63 is moved to allow an arm 55 and an actuator 50 to move forwardly until a pin 57 in the arm engages the stem of a depressed key. A control bar 67, moved forwardly with the actuator, is locked by a bar 83 and a setting rack 76 for the indicator and printing mechanism is moved into a corresponding position by a rod 86 which acts on a pair of arms 72, 74 pivoted together, and to the setting rack and control bar respectively. In alternative arrangements the arms 72, 74 are pivoted together at their centres and the rod 86 acts on the free end of each. In one of these arrangements, the control bar and actuator are integral with one another. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 644,120. This subject-matter does not appear in the Specification as accepted.
