Patent GB-1315065-A (GB)
Title: Linear three-dimensional gauging and form measuring machine
IPC: B43L13/00
Filed: 1971-04-19
Abstract: 1315065 Plotting instruments CLEVITE CORP 19 April 1971 [8 April 1970] 26660/71 Heading G1X [Also in Division H4] Relates to an arrangement for scanning a surface of a three-dimensional object and reproducing the resulting signals on a two-dimensional record with an apparent three-dimensional appearance. The surface of the object e.g. a coin, is X-Y raster scanned by a pick-up stylus sensitive to motion in the Z-axis direction, and the resulting Z-axis motion signal from the stylus is applied to the Y-axis (slow scan direction) deflection means of a recording device (e. g. a pen recorder) which is scanned synchronously with the scanning of the object. A three-dimensional contour-like map of the surface of the object is thus produced by the recording device due to the additional deflection of the recording pen in response to the Z-axis motion signal i.e. hill-and-dale movement of the pick-up stylus. A reciprocating scan may be employed although preferably a one-direction raster scan is used, the recording pen being lifted clear of the record chart on return scans. The Y-axis scanning of the object may be continuous of incremental. The object and/or the stylus may be moved to effect the scanning. In recording every nth scan may be omitted or replaced by a dashed line. An isometric view of the specimen may be recorded.
Patent GB-1043422-A (GB)
Title: Manufacture of organoaluminum compounds
IPC: C07F5/06
Filed: 1963-07-05
Abstract: Trialkylaluminium compounds are prepared by chain growing ethylene molecules on the alkyl groups of a tri-lower alkylaluminium compound feed, separating the formed mixed trialkylaluminium compound stream into the desired tri-higher alkylaluminium compound fraction and a tri-lower alkylaluminium compound fraction by a solvent extraction process, and recycling at least a portion of the tri-lower fraction to the chain growth step.  The growth reaction product may be contacted at e.g. 14-104 DEG  F. and 200 p.s.i.g. in a packed or rotating disc column with a solvent, such as a haloalkane containing at least one fluorine atom, with which the alkylaluminium compounds are only partially miscible, to yield a solution enriched in the lower alkyl components. These are separated by distillation and recycled to the chain growth step and the solvent, with make-up solvent returned to the extraction step.  The higher alkyl components in the residue is fractionated from components of very long chain length and excess ethylene. Alternatively, the components of the chain growth product may be distributed between two partially miscible solvents, for example a haloalkyl ether, di-lower alkyl ether of a glycol or of a polyglycol as first solvent, and a saturated alkane having 3 to 22 carbon atoms as a second solvent. The first and second solvents dissolve fractions enriched in lower and higher alkyl aluminium compounds respectively, and these are fractionated in vaporizers, the solvents, with make-up solvent, being returned to the extraction step, the lower alkyl fraction to the chain growth step and the higher alkyl fraction recovered as the desired product.

Abstract: 1,168,035. Washing apparatus. SCOTTS ELECTRICAL WHOLESALERS Ltd. 5 June, 1968, No. 26721/68. Heading B8T. [Also in Division F2] An apparatus for washing and decontaminating surgical rubber articles comprises a cabinet 10 in which is mounted a bowl 11 having a motor 14 on its bottom, driving an impeller 12 and a pump 16 with an outlet 17 connected to a conduit 18 having outlet pipes 19, 21, 22 and 23. A hot water tank 25 fitted with an immersion heater 26 is mounted below bowl 11 and has a valve controlled inlet 27 and an outlet 25a connected to the bowl. A drain outlet 30 in the bowl is controlled by a solenoid 34 through arm 32. A micro switch and float arrangement keep the water level in bowl 11 constant. A detachable frame, on which items to be cleaned can be placed, can be lowered into the bowl. In operation, the various rubber items to be cleaned are placed on the vertical pipe or on frame. The lid 39 is then closed, a micro switch 41 actuating an automatic sequence of cleaning operations. First, hot water from tank 25 is forced into the bowl when valve 28 opens, the water being recirculated for 2 minutes by motor 14. The drain 30 is opened to empty the bowl; this is followed by a half minute drain period. The disinfecting cycle then begins, the water temperature in the bowl being raised to 190‹ F. by a heater 35. This cycle lasts 10 minutes. The process should ensure decontamination of the articles without damage to the rubber material of which they are made.

A conductivity measuring head comprises a pair of plate electrodes 11, 12, Fig. 1, screened from each other by a larger plate 10, the plate 10 being insulated on both sides and the whole being encapsulated by an insulating surround 14. The outer electrodes may be deposited on the insulation 13 and the outer surface may be thinly insulated so that liquid into which it is to be inserted for, for example, liquid level measurement is capacitatively coupled to the electrodes. The current to one electrode 12, Fig. 3, from an A.C. source may be opposed by current through a standard impedance 23 and applied to a null detector 30 through a rectifier 29. In an alternative arrangement, Fig. 4, the current through electrode 12 is measured by applying a signal proportional to it, to a high-gain amplifier having a degree of feedback sufficient to give a substantially zero input, the amplifier voltage output then indicating the current. Alternatively a current indicator may be inserted in the feedback path. In a further arrangement described with reference to Fig. 5 (not shown) the current measured by the amplifier is the difference between the electrode current and a reference current, the latter being injected in the amplifier input circuit.
