Title: Semiconductor memory
IPC: G11C11/41
Filed: 1973-06-15
Abstract: 1369767 Transistor pulse circuits INTERNATIONAL BUSINESS MACHINES CORP 15 June 1973 [5 July 1972] 28629/73 Heading H3T In a semi-conductor memory a bit driving circuit T8-T14 is arranged to write binary information into a storage cell 10 associated with a sensing circuit 12 by changing the potential of a bit/sense line to alter the relative potential between a pair of bit/sense lines B/S0, B/S1 and restoration of the affected line to its original potential immediately after a write operation is enabled by a charge path, e.g. via the base emitter path of transistors T 101 , T 102 , from a potential source to that line. In operation, a "0" or a "1" is written into the cell by respectively rendering transistors T 6 , T 7  conductive by the application of suitable control pulses to transistors T 8 -T 14 . After the write operation, transistors T 6 , T 7  are both non- conductive and a transistor T 14  is also non- conductive so that one of transistors T 101 , T 102  conducts to rapidly charge the capacitive load provided by cell 10 to bring the affected bit sense line from a down level to its normal up level. During quiescent as well as during read out periods, transistors T 6 , T 6  are non-conducting so that bit/sense lines are maintained at an up level and circuit 100 including transistors T 101 , T 102  is also out of operation.

Title: Conveyor systems
IPC: B61C13/04
Filed: 1970-06-15
Abstract: 1359823 Conveyer system; vehicle spacing control CRISPLANT AS 15 June 1971 [15 June 1970] 28861/70 Headings B7L and B7N A conveyer system comprises a plurality of driving units, so-called dogs 4, which are provided with driving motors so as to be individually driven along guiding rail means 2 and releasably connectible by pulling rods 6 to movable carrier vehicles 10 for movement thereof between loading and unloading stations, spacing control means being provided to ensure a normal operational minimum spacing between consecutive vehicle-loaded dogs, and means being provided to deactivate the spacing control means between an idle (i.e. unloaded) dog and the foregoing or following dog to allow these dogs to move closer together to an absolute minimum spacing, at least along selected lengths of the rail means. The spacing control means may include sensing means in the form of a mechanical feeler rod 22 which operates switch 20 to stop the driving motor when swung rearwardly by contact with the vehicle 10 connected to the foregoing dog. Alternative vehicle sensing means may be an ultrasonic transmitter and receiver unit 20<SP>1</SP> (Fig. 1) mounted on the dog 4. Pulling rod 6 is biased to swing upwardly when disconnected from a vehicle 10, thus operating a detector switch 50 (Fig. 5) to deactivate the spacing control means. Spacing control may be achieved by means for detecting the normal minimum spacing being reached between consecutive dogs. Such means may use the transmission and detection of radiated signals between dogs (Figs. 3 and 4, not shown) or use "puppies" 52 (Fig. 5) attached to each dog 4 by flexible pulling wires 54 and having switch actuators 56 to actuate switches 58 or 14 on the following dog, stopping its motor when it catches up with the puppy. In another form (Fig. 8), electrical means detect the nearness of the following dog and cut off the following dog's power supply by relay 78 operating switch 79. This occurs when sliding shoe 66 of a following dog contacts a section 62 of control rail 60, the section 62 being connected via wire 64 and section 61 to sliding shoe 68 of the next dog forward. Alternatively, a photo-cell (104), Fig. 9 (not shown), on the following dog may be activated by light from a lamp (94) which is activated by the next dog forward. A front end stop switch 14 (Fig. 1) stops the motor of an idle dog when it catches up with the foregoing dog, to maintain the absolute minimum spacing therebetween.

These grooves are coated with a conductive layer, and each inner coating is connected to each member 6 by a wire 18. Hoods 16 and 17 screw onto the caps 4, 5 and secure the series of condensers together. In a modification, Fig. 2, each metal portion of the tube is grooved, and wires 21, 22 secured to a ring 22 rest in the grooves. The ring 23 fits between two condensers so that the inner coating of one and the outer coating of the other abut against it and so are connected to the member 18. The condensers may be made of porcelain or an artificial resin and may be coated by a metal extruding or projecting process.

Title: Petroleum middle distillate fuels
IPC: F02B3/06
Filed: 1958-09-11
Abstract: Petroleum distillate fuels boiling between 300 DEG  and 900 DEG  F., e.g. heating oils, diesel fuels, jet engine fuels, kerosine, are stabilized by the addition of from 0.05 to 1% by weight of an alkylene polyamine sulphonate containing from 2 to 4 carbon atoms in the alkylene polyamine group.  The sulphonates may be derived from a petroleum sulphonic acid obtained by treating a middle distillate petroleum fraction containing alkyl aromatic hydrocarbons with sulphuric acid or oleum, or a synthetic sulphonic acid obtained by similar acid treatment of alkyl aromatic hydrocarbons prepared by alkylating, e.g., benzene, toluene, and naphthalene with a polyolefin such as polypropylene containing from 9 to 15 carbon atoms per molecule.  Synthetic sulphonic acids specified are dinonyl naphthalene sulphonic acid and polypropyl benzene sulphonic acid. Alkylene polyamines specified are ethylene diamine, diethylene diamine, diethylene triamine and trimethylene diamine.  The alkylene polyamine and sulphonic acid may be reacted in approximately stoichiometric proportions.
