Abstract: 1466261 Lubricants SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 7 March 1974 [9 March 1973] 11455/73 Heading C5F In the non-destructive deforming of metals, the lubricant used is a suspension in a non- volatile hydrocarbon oil of a thermoplastic rubber which is a block copolymer comprising non-elastomeric blocks A of a monoalkenylarene and elastomeric blocks B of a conjugated diene, which blocks may be partially or completely hydrogenated. The number of blocks B is preferably one, but may be up to 5; the number of blocks A is one more than the number of blocks B. "Non-volatile" is defined as not more volatile than spindle oil, which is the preferred hydrocarbon oil. Preferred monomers are styrene and butadiene or isoprene.

IPC: B01L3/02
Filed: 1965-03-18
Abstract: A pipette (see Division B1) is formed out of a single glass tube as illustrated in Figs. 5-7 (not shown), by assembling a pair of shell sections 18, 20 and a ring 22 on a hollow mandrel having capillary section 161 and a larger bore portion 1611, shrinking a wide bore glass tube 14 on to the assembly by applying heat and reduced pressure whilst cooling the mandrel and finally withdrawing the mandrel and dissolving the shell and ring.  As the glass is softened adjacent the shell sections and ring a sudden vacuum of short duration is applied causing the blank to shrink in sharp conformity with the shell sections and ring.  Reference has been directed by the Comptroller to Specification 866,519.ALSO:A pipette suitable for the accurate dilution of blood samples comprises, in the end wall of the bulb 6 (Fig. 2, not shown) adjacent to the liquid withdrawal tube 5 of capillary dimension, a cylindrical well 9.  The glass forming the wall of the well 9 and of the adjacent capillary tube and bulb are substantially free from internal stresses and optical distortion. The pipette is formed out of a single glass tube, e.g. as illustrated in Figs. 5-7 (not shown), by assembling a pair of shell sections 18, 20 and a ring 22 on a hollow mandrel having capillary section 161 and larger bore portion 1611, shrinking a wide bore glass tube 14 on to the assembly by applying heat and reduced pressure and finally withdrawing the mandrel and dissolving the shell and ring.  A glass mixing bead 10 may be included in the shell before shrinking.  In use, the capillary tube is placed in the blood sample, which rises therein to the clearly defined and easily visible level of the bottom of the well, and diluent is then aspirated into the pipette to mix with the blood and rise to a marked level 12.  Reference has been directed by the Comptroller to Specification 866,519.

Filed: 1940-07-16
Abstract: 541,739. Selenium cells. VESZI, G. A. July 16, 1940, No. 11757. [Class 40 (iii)] In making photo-electric cells of the kind comprising a selenium base coated with a composite metallic layer by successive cathode sputterings, (1) the first layer is very thin, namely of a thickness which if applied under identical conditions to a transparent or white surface would make the layer only just visible ; and (2) the first laver may be gold and the second layer cadmium. Diffusion between the layers is accelerated by increasing the temperature during the sputtering process for example automatically by the gas discharge. A layer of gold may be applied to the cadmium layer for picking-up the current; this gold layer may be applied by cathode sputtering at a low temperature say 20‹ C. to avoid diffusion. The selenium base may be a film applied to a plate of iron and heated to become light sensitive.

Abstract: 1,014,402. Automatic exchange systems. SIEMENS & HALSKE A.G. March 23, 1964 [March 22, 1963], No. 12109/64. Heading H4K. Metering pulses are detected and added to a total stored in a register such as a magnetic drum SP, the metering pulses occurring on lines associated with each of which is a magnetic core such as Kxy of a matrix M, the cores being scanned for the registration of a meter pulse by means of pulse pairs a, b, the spacing between each pair of which is greater than the space between members of each pair. Each scanning pair can produce four possible results depending on whether the pair straddles the beginning or the end of a meter pulse or lies wholly within or without the pulse. The rows of the matrix M are read out in sequence by a pulse distributer TVZ producing a pulse pair train for each row. The core states of each row are inscribed in parallel in an intermediate store AR1, the result of the b-pulse being recorded in store E2 and the result of the a pulse being recorded in store E1. The a-pulse core states and the b-pulse core states are then read-out together for each core of the matrix M and serially for the cores of each row by a pulse distributer. TVS. The results of scanning are thereby presented to an evaluating circuit AS as a sequence of coincident binary signals el and e2. A second intermediate store ARZ is employed in conjunction with the store AR1, the one store receiving read-out from the matrix while the other is read out to the evaluating circuit AS. For each position of the scanning sequence the related subscriber's meter record is read out of the store SP and is re-written by way of a circuit AD which will cause the addition of one unit under command of the evaluator circuit AS. Addition is demanded by a signal a1, an accompanying signal a2 being recorded on the drum and being reproduced after a delay of one scanning period to provide an input e3 to the evaluation circuit A5 so as to inhibit a second consecutive demand for addition. Figs. 2 to 5, not shown, indicate gating circuits suitable for the evaluator circuit AS. Conditions are set out governing the scanning rate and pulse dimensions in relation to meter pulse repetition rates and dimensions. Meter pulses may have no spacing and constitute a continuous signal the duration of which indicates charge.
