Title: Sheet handling method and apparatus e.g. in collating apparatus
IPC: B65H29/58
Filed: 1964-08-04
Abstract: 1,041,892. Delivering sheets. MIEHLE-GOSS-DEXTER Inc. Aug. 4, 1964 [July 26, 1963], No. 30837/64. Heading B6H. A sheet handling apparatus associated with a sheet or signature collating machine comprises a sheet transfer means 10, Fig. 1, including a plurality of parallel, spaced rotatable discs 11 for sequential feeding of the sheets secured to the discs by grippers 15 to a plate 30. The plate 30 has bevelled surfaces 31, Fig. 2, to facilitate transfer of the sheets from the discs to the plate. The sheets transferred to the plate 30 are then advanced by conveyer belts 32 and pivotally mounted rollers 40 co-operating with the belts to a sheet direction changing mechanism 46 comprising a stationary arm 47 and a rotating arm 48 having attached to its ends revolving forwarding brackets 49. At the end of each of the brackets there is positioned a pair of vacuum operated sheet-engaging means 70, 71, each terminating in a sucker 75. As the trailing edges of the sheets leave the nip formed between the rollers 40 and belts 32, the rotating suckers 75 are lowered to engage the leading portions of the sheets and whilst the arm 48 and brackets continue to rotate the suckers 75 transfer the sheets along a circular path into a gathering conveyer 90, travelling in a direction displaced at 90 degrees to the direction of belts 32, the suckers depositing the sheets between fingers 94 of the conveyer. The arm 48 is driven in a clockwise direction by a chain 61, whereas the brackets 49 are driven anticlockwise by chains 67 and the longitudinal axes of the brackets 49 stay normal to the direction of travel of the sheets along the plate 30 so that the orientation of the sheets during transfer and release on to the conveyer 90 remains unaltered.

Patent GB-265336-A (GB)
Title: Process for making lactic acid and lactates
IPC: C12P7/56
Filed: 1925-12-08
Abstract: 265,336. Faithfull, S. E. Dec. 8, 1925. Lactic acid and lactates are produced by fermentation, a gaseous oxidizing material containing free oxygen being introduced to retard the production of butyric acid, and impurities being removed from the lactate solution after fermentation. In an example a hydrolyzed carbohydrate (glucose) is subjected to fermentation with lactic bacteria in slightly acid solution. Slaked lime or calcium carbonate is added to neutralize the acid formed and oxygen or air is injected during the fermentation and as long as calcium lactate is present in the liquor. The solution is then made slightly alkaline and heated nearly to boiling point, which converts any carbohydrates remaining into caramel, which can be filtered off. The solution is concentrated, acidified, and lead lactate or other lead salt or tannin is added to precipitate the nitrogeneous matter present, from which, after filtration, nitrogen may be recovered as ammonia by heating. The solution may be purified by activated carbon and any heavy metals precipitated with sulphuretted hydrogen, leaving a colourless solution of calcium lactate, from which calcium lactate, calcium acid lactate, or lactic acid may be obtained in known manner.

Abstract: 1,190,560. Automatic exchange systems. STROMBERG-CARLSON CORP. 10 July, 1967 [21 July, 1966], No. 31571/67. Heading H4K. In a switching network each link circuit has its own originating and terminating transistor cross-point matrices, subscribers' lines having no line circuits and being multipled over corresponding appearances in the matrices of each link circuit. In a link circuit the terminals of a feed transformer 10, shown partly in Fig. 1 and partly in Fig. 2, are each multipled to the rows of 10 x 10 matrices by way of coupling transistors such as 26-29. Each of the two wires of a subscriber's line is connected to the collector of corresponding transistor cross-points in the originating matrices of Fig. 1 and is similarly connected to the collectors of corresponding cross-points in the terminating matrices of Fig. 2. When allotted for use the originating matrices of a link are scanned by applying suitable potentials on the row and column leads so as to sequentially prime the transistors in each leg of each subscriber's line. If a line so scanned is looped in the calling condition, the matrix transistors in each leg conduct and relay ARS operates to seize the link and connect a register. Line scanning is now transferred to the next link allotted for use. Busy testing and termination to wanted lines is effected in an orthodox manner. Diodes in the collector circuits allow a large cut-off bias to guard the cross-points against transients. Diodes in the emitter circuits provide protection against reverse breakdown voltages. The transistors in each leg of a line are preferably of opposite type, as shown.

Title: Improvements in or relating to the construction and operation of oil tankers
Inventor: LAMB JOHN
IPC: B63B27/24
Filed: 1958-10-10
Abstract: <PICT:0847199/III/1> <PICT:0847199/III/2> <PICT:0847199/III/3> A method of recovering oil from sludge in an oil tanker (see Group XXXIII) comprises passing the oil and/or sludge and water originating from oil-carrying tank washing operations to a separating tank 12 and allowing the mixture to spread over the surface of the fresh water that partially fills the tank.  The temperature of the tank 12 is raised by heating coils to accelerate the separation of the oil. During the washing operations the clean water in the tank 12 is recycled for further tank-washing operations and, on completion of these operations, is discharged overboard.  The oil residues, sediment and water remaining in the tank 12 are pumped to a sludge tank 13 and heat is applied to this tank for sufficient time to allow the remaining small quantity of water to separate and be drained off. The oil left in the tank 13 may be suitable fuel for the tanker's engines; if not it is pumped via a service tank 16 and a preheater 18 to a distilling plant situated on the tanker's deck.  The service tank 16 has a sloping bottom to reduce the possibility of "slugs" of water being drawn into the distilling plant.  The oil, water vapour and oil vapours pass into the distillation column 19, which comprises six equally-spaced and inclined trays a-f attached to a vertical shaft 27, and the vapour separated from the mixture passes out to amosphere through the upriser 22, any condensate collected being removed and disposed of.  The liquid portion of the mixture passes down to the re-boiler 20, which is heated by a steam coil 23 and a steam pipe 24, and further evaporation takes place.  The oil in the re-boiler 20 is kept at a constant level by an outlet valve 26 controlled by a float 25.  The mixture is passed back to the tank 16 and recirculated until it has the required flash point.  It is then directed to a fuel storage tank from whence it can be drawn for use in the tanker's engines. Specification 743,713 is referred to.
