Patent GB-1239685-A (GB)
IPC: C10M159/20
Filed: 1969-10-03
Abstract: 1,239,685. Overbased additives. ESSO RESEARCH & ENG. CO. 3 Oct., 1969, No. 48644/69. Addition to 1,200,922. Heading C1A. Basically-reactive additives are prepared by reacting a group I, II or III metal or its carbide or hydride with an alcohol in the presence of an oil soluble dispersant until alcoholate formation is complete and then heating the reaction mixture to a temperature of at least 80‹ C. with an acidic reagent. The metal reagent is preferably calcium carbide and the alcohol is preferably an ether alcohol containing not more than six carbon atoms. The oil-soluble dispersant may be a sulphonate with a sulphonic acid radical having molecular weight between 350 and 1000; a phosphorus sulphide-treated hydrocarbon such as a phosphorus sulphide treated polyolefin in which the polyolefin has a molecular weight between 500 and 1500; a carboxylic acid or a metal soap thereof. The dispersant is preferably dissolved in oil before use in the reaction. The reaction mixture is preferably initially heated under reflux at a temperature above 100‹ C. for at least four hours. The acidic reagent is preferably hydrogen sulphide. After treatment with the acidic reagent, alcohol is distilled off from the reaction mixture to leave the desired additive as a colloidal dispersion in the dispersant. The properties of the additive are improved by a heating with elemental sulphur at above 180‹ C. for between 4 and 12 hours. The odour of the additive may be improved by adding a base such as an alkali metal hydroxide or by heating to at least 80‹ C. with an alkylene oxide.

Abstract: 1,250,924. Digital transmission systems. STANDARD TELEPHONES & CABLES Ltd. 25 June, 1969, No. 32092/69. Heading H4P. Digital data words transmitted have disparity which varies in a predetermined manner. The receiver determines the variations in disparity expected and compares those with the variations actually received. Lack of identity indicates an error. As described 3-digit words comprising +, 0, and - digits are transmitted, each representing a 4-bit word. Each word has + or 0 disparity until the total disparity of all the transmitted digits reaches + 1 or more, whereupon the words are transmitted inverted, i.e. have - or 0 disparity until the total disparity reaches - 1 or more. This manner of variation of the disparity has the effect that when a word + 1 disparity is followed by a word of - 1 disparity (or vice versa), no words of other than 0 disparity lying between these words, the total disparity after reception of the second unit disparity word is the same as the disparity of that word. At the receiver, Fig. 2 (not shown), each 3- digit word is converted to parallel form to feed a unit generating a corresponding 4-bit signal which is serialized and passed to the output. A counter determines the disparity of each received word and another counter determines the total disparity. The occurrence of successive opposite unit disparity words is detected by monitoring the word disparity count and causes the outputs of the counters to be compared. If they differ, the total disparity counter is reset to the current word disparity count and an error is indicated. A further unit determines the rate at which errors occur. If this rate is excessive it is assumed that word synchronism has been lost and a control signal is then passed to a circuit which derives a word rate clock signal from a digit rate clock signal, the control signal causing the word rate clock signal to be shifted in phase by one digit period in an attempt to restore sync.

Abstract: 1,257,447. Feeding sheets. NORTH AMERICAN ROCKWELL CORP. 15 Oct., 1970 27 Oct., 1969], No. 48956/70. Heading B8R. In order to compensate for misregister in machines such as multi-colour sheet printing machines due to "fan out" or change in lateral dimension of the trailing part of a sheet caused possibly by absorption of moisture or by anironing effect as the sheet passes through the machine, the grippers carrying a sheet from a feed table to an impression cylinder are operated so that as they start their feed movement, they cause a bowing of the front edge of' the sheet which in turn causes the side edges of the sheet adjacent to the trailing part to be moved towards or away from one another to restore the sheet width at the trailing part toits normal dimension. As shown in Figs. 5, 7 an oscillating shaft 31 carries the gripper structure which comprises a number of pivoted arms 73 with camcontrolled gripper fingers 61 each adapted to engage the roughened surface 57 of a gripper pad 51, after the sheet 15 has been registered against a front stop 13 on a table 11. The pads 51 are attached to a resilient transverse bar 50 which is attached to the arms 73 by bolts 101 with a certain amount of play. For this purpose, square sleeves 104, Fig. 5, slightly longer than the bar thickness are mounted on the bolts 101 and are pressed against the arm 73 by washers 102 on the bolts, and springs 107 press the bar 50 against the washers 102. A fixed member 125, Fig. 3, carries three stops 121 which can be adjusted by screwed spindles 132 so that as the grippers approach the sheet-receiving position, they abut against surfaces 136 on the bar 50 situated between the pads 51, one stop being centrally of the bar 50 and the other two near its ends. The stops 121 cause bowing of the bar 50 at the sheet-receiving position, but as the grippers start their feed movement, the bar 50 being separated from the stops reverts to its normal straight condition thus causing bowing of the front edge of the sheet with resulting alteration of the width of the sheet at its trailing edge. The stops may be set to cause increase or decrease of the width at the trailing edge according to requirements.
