Abstract: 1,187,014. Milking apparatus. I. V. DAWSON. 7 April, 1967 [7 April, 1966], No. 15646/66. Heading A1M. [Also in Divisions F4H and F4S] A supply pipe 14 delivering liquid to a device 16 for cooling the liquid, incorporates means 15 for damping out fluctuations in the flow of liquid along the pipe, the cooling device 16 (not shown in detail) being one comprising a container having means therein for distributing liquid to be cooled over a cooling surface located within the container. In the cooling system shown for milk delivered to the cooler 16 from pulsator milking machines 11, the said damping means 15 consists of a reservoir arranged in a line 14 by which milk is delivered to the cooler 16. The reservoir has a removable lid and a renewable filter element for the milk. From the cooler 16 the milk passes via a flexible tube 20 either into churns 21 or into a bulk storage tank. The churns 21 (or the bulk storage tank) are connected via a line 22 with the vacuum line 12 in which the vacuum is maintained by a pump 9. Milk from the cows enters the line 14 by way of pipes 13 attached to the milking machines 11 and the flow pulsations produced by these machines are said to be damped out by the reservoir 15 before the milk reaches the cooler 16. The degree of vacuum is controlled by a pressure regulator 41 which allows air to bleed via vent 43 and pipe 42 into the vacuum line. Means for cleaning the equipment by flushing in known manner is described. The cooling element in the cooler 16 may comprise the evaporator chamber of a refrigerator 19, in which case the pressure in the evaporator chamber may be controlled (e.g. by a valve responsive to the pressure on the suction side of the compressor) so as to prevent freezing of the liquid on the wall of the chamber. The element itself may consist of one or more helical or circularly bent tubes, or a hollow plate consisting of two channelled members disposed face to face. These may be bent to annular form. When the cooler discharges into a bulk storage tank, the liquid may be recirculated continually between the cooler and the tank. Alternatively the bulk storage tank may itself comprise the cooler.

Title: Preparation of eta alumina
IPC: C01F7/36
Filed: 1957-05-20
Abstract: A mixture of alcohols, normally having from 2-20 carbon atoms, is produced inter alia in the hydrolysis of aluminium alcoholates to precipitate alumina (see Group III).  The alcoholates are obtained by reacting a C2-C4 olefin with a compound of formula: <FORM:0844637/IV(b)/1> where R1 is a C2-C8 alkyl group and R2 and R3 are C1-C8 alkyl groups or hydrogen, to form a mixture of aliminium trialkyls of higher molecular weight, e.g. in which the alkyl groups contain 2-20 carbon atoms, and oxidising said trialkyls to a mixture of the corresponding alcoholates.  The preferred olefin is ethylene and initial aluminium alkyl compounds specified are aluminium triethyl, tripropyl, tributyl and triisobutyl, aluminium diethyl hydride and aluminium ethyl dihydride.  The first reaction may take place at 85-120 DEG C. and 200-5000 p.s.i.g. in a reactor having several sections packed with Raschig rings over a period of 1-30 hrs. to give products having three similar alkyl groups with 4, 6, 8, 10, 12 or 14 carbon atoms or three different groups e.g. <FORM:0844637/IV(b)/2> a diluent such as a C6-C8 paraffin, benzene, toluene or xylene may be employed.  The aluminium trialkyl is then oxidixed, preferably with air at 0-90 DEG C. and 0-500 p.s.i.g.; a diluent such as hexane, heptane, octane, benzene, toluene, or a solvent naphtha having a boiling range of 200-400 DEG F. may be used. Specifications 760,081 and 827,392 are referred to.  Reference has been directed by the Comptroller to Specification 667,145.ALSO:In the production of c -alumina by hydrolysing aluminium alcoholates, ageing to form b -alumina trihydrate and calcining at 260-800 DEG C., the alcoholates are prepared by reacting an olefin with a compound of formula:  <FORM:0844637/III/1> where R1 is a C2-C8 alkyl group and R2 and R3 are C1-C8 alkyl groups or hydrogen, to produce a mixture of aluminium trialkyls of higher molecular weight, e.g. in which the alkyl groups have 2-20 carbon atoms, and oxidising said trialkyls to a mixture of the corresponding aluminium alcoholates (see Group IV(b)).  The hydrolysis of the alcoholates (which may be a solid or liquid and may be hydrolysed in solution in e.g. n-heptane) may be performed by spraying into water (as in Specification 760,081) or an aqueous solution of an organic or volatile inorganic acid (as in Specification 827,392) or an aqueous solution of ammonia.  The mixture is preferably stirred during hydrolysis.  The alumina is then aged, preferably without agitation, at temperatures depending on the hydrolysis, and if desired in the presence of b -trihydrate seeds. Reference has been directed by the Comptroller to Specification 667,145.

Title: Optical beam deflection arrangements
IPC: G02F1/29
Filed: 1974-04-11
Abstract: 1465621 Deflecting light WESTERN ELECTRIC CO Inc 11 April 1974 [16 April 1973] 16109/74 Heading G2F In a deflector for a monochromatic plane polarized beam 12, a series of parallel electrode strips 401-408 is disposed on only one major surface of a strontium niobate plate 14 supported on a transparent substrate 13. The beam 12 has at least a component of propagation perpendicular to the plane of the plate, and its polarization is related to the crystal out of the plate and the type of signal applied to the electrodes such that it is locally phase modulated. In Fig. 3, electrodes 405-408 are fed with sawtooth voltages V 5 -V 8 , of the same peak amplitude V, and with respective frequencies f, 3f, 5f and 7f, while electrodes 401-404 receive voltages V 1 -V 4  where V 1  = -V 8 ; V 2  = -V 7  &c., and it is the component of the resulting electric field perpendicular to the plate which produces phase modulation. V is chosen to produce a phase change of Œ # at the electrode to which it is supplied. The effective phase modulation # across the device at any time (X-direction) is as shown in Fig. 4, although in actual fact # should be plotted (modulo 2 #). It is said that radiation transmitted through the electrodes is diffracted, and that radiation between the electrodes is refracted in the same direction, there being a substantially linear variation in # between a majority of adjacent electrode pairs (but not all pairs since # is modulo 2#), and hence that the beam undergoes a sawtooth deflection with frequency f. In Fig. 5, phase modulation is due to the electric field component in the plane of the plate, and likewise gives refraction and diffraction of beam 12 in the same direction. Pairs of electrodes are electrically common, and are connected as shown with other pairs by equal constant current devices I, and by pulse circuits Q 1 -Q 3  which transfer equal amounts of electricity per pulse but operate at different frequencies and times such that the charge stored on the electrodes varies in the manner shown in Fig. 6. Thereby, overall electrical neutrality is maintained, and at any time the charge on one side of any particular point along the X-axis is a linear function of its position, apart from the modulo Q factor, where Q is the amplitude of Q 501 , Fig. 6, and is the charge required to produce a 2 # phase change. The beam 12 is deflected with a frequency equal to that of the sawtooth Q 504 , Fig. 6. In either embodiment, the sawtooth variation of voltage or charge may be as a function of some input signal, rather than as a function of time, for providing analogue deflection. Fig. 3 or 5 may be modified by the use of mirrors or reflective electrodes to form reflective deflection gratings. In Fig. 1 (not shown) an array of stripe optical stops parallel to the electrode is provided on the side of the substrate 13 nearest source 11. The electrode width is 0.3 to 0.5, and preferably 0.4, of the repetition distance of the array, when both refraction and diffraction are utilized.
