Abstract: 984,668. Reciprocating pumps. ALPURA A.G. Nov. 26, 1962 [Nov. 27, 1961], No. 44699/62. Heading F1A. A pump for the homogenisation of milk includes a plunger 6 actuated by a crank (not shown) and the plunger passes through a gland 11, 12, 13. Before pumping, the pump is sterilised by passing a sterilising agent such as hot water or superheated steam into the bore 2 with the pump running and into a bore 19 leading to a clearance space 16. This space is as long as or preferably longer axially than the stroke 7 of the plunger. When the pump has reached sterilisation temperature, pumping of the milk commences and the pump is kept at strilisation temperature by passing the sterilising agent through the clearance 16. This also prevents any part of the plunger which passes into the pump body from coming into contact with the atmosphere. In an alternative embodiment the plunger may be supported by two axially spaced glands and a controlled flow of sterile coolant passed therebetween to regulate the pump temperature, the clearance 16 through which sterilising agent is also passed being located beyon the second seal. In a further alternative the open end of the clearance 16 may be closed by a second seal and the flow of sterilising agent therethrough regulated.

Abstract: 1,195,156. Wells &c. SCHLUMBBRGER TECHNOLOGY CORP. 24 Sept., 1968 [5 Oct., 1967], No. 45264/68. Heading E1F. A well packer B has a valve C with a valve sleeve 27 which is rotated by reciprocating a running string having a running tool A. The .packer is run into the well with parts positioned as shown, a tool extension 45 telescoping into the .packer body 11, the slips .14, 72 of the packer being retracted, and the slips 72 being held by a sleeve 80 depending from: a drag assembly 92 mounted on the tool. The valve is open, ports 28 on the sleeve 27 registering with ports 26 in .the body, and pins 35 on the sleeve 27 being engaged by slots 62 in the extension. Pins .104 on the body are positioned at D in a groove network 105 on the extension. The string is rotated to turn a sleeve 88 relative to the drag assembly to move assembly and sleeve 80 .upwardly to free the slips 72 .and to free sleeve 88 and a depending sleeve 101 from the tool part 38 which carries the extension. The string and the tool parts 38, 45 are raised relative to the drag assemlbly to cause pins 104 to move to positions E in the network to cause rotation of the extension to close the valve. Further upward movement of 'the string raises the body 11 as lugs 52 on the extension engage a shoulder 56 on the body. The initial upward movement of the body causes expander 17 to set slips 72, the slips 72 being held against longitudinal by the sleeve 101. Further upward movement .expands packing 16 and sets the slips 14, the set packer being retained in set condition by a ratchet ring 20. The string is slacked off, the resultant downward movement of the extension causing the pin 104 to take up positions F in the network, and the extension and valve :sleeve to turn although the valve remains closed. The string is picked up to remove the tool, the pins 104 moving out through .exit slots 107 in the network and the lugs passing through gaps in the shoulder, and the valve remaining closed. The tool may be reinserted to open the valve. The slot 62 in the extension are shaped' to give a .lost motion connection with the pins of the valve sleeve so that the packer may be lowered with the valve closed. Wire line tools may be substituted for the tool A and the tool is used for cementing.

Abstract: 1485015 Semi-conductor devices MULLARD Ltd 25 March 1975 [29 Oct 1974] 46726/74 Heading H1K In a semi-conductor body comprising an N-type layer on an N + -type substrate 1 there is formed a mesa 5 having a side bevel such that the areas of the mesa increases upwards from the NN+ interface, whereby the whole upper edge of the mesa 5 overhangs the bevelled side. The mesa 5 is produced by etching, at least a part of the etching process employing an etchant which removes the N+ substrate material more quickly than the N-type material. In one embodiment a non-selective chemical etchant is used initially to form the mesa and this is followed by an electrolytic etchant which preferentially removes N+ material. The bevel may form during this step, but if the electrolytic etchant is not effective at all on the N-type material a subsequent non-selective chemical etal is required to bevel the mesa side. Alternatively a gas plasma etal of CF 4  may be used which, when it also contains 2-4 vol. per cent of oxygen, preferentially attacks N+ material. In this case a metal layer (e.g. of Al or Cr or Au on Pd on Ti) serves as the etch mask whereas a combination of nitride and oxide layers is used when a liquid etchant is employed. To form the PN junction avalanche diode shown boron is implanted or diffused into the upper surface of the mesa to form P-type layer 8, an oxide coating 7 and/or the overhang of the mesa walls serving to mask the remaining semiconductor surface. An electrode 10 of Au on Pt, Pd or Ti is deposited on the top of the mesa.

They may be obtained by subjecting a corresponding salt having a moisture content exceeding 3% by weight to a drying process to reduce the moisture content to the maximum 3% by weight. Drying may be effected by use of a desiccant, e.g. under reduced pressure or vacuum, by freeze drying, vacuum-spray drying or by azeotropic dehydration. The drying should generally be carried out at a temperature not exceeding 30‹ C. to avoid risk of decomposition. Specified desiccants are P 2 O 5 , CaCl 2 , SiO 2  and H 2 SO 4 . Absolute hydrophylic organic solvents such as alcohols, acetone and dioxane may also be used to effect dehydration. A desirable method comprises first drying to a certain moisture content, e.g. from 3 to 10%, or less, e.g. by freeze drying, and then (if necessary), lowering the moisture content to 3% or less by use of a desiccant. Examples are given (a) for reducing the moisture content of the sodium salt to 0À88% and then to allow the moisture content to rise to 1À86%, 2À57% and 6À37% respectively the latter being for comparative purposes, and (b) for reducing the moisture content of the potassium salt first by freeze-drying and then by P 2 O 5  desiccation to 0À63% and then to allow the moisture content to rise to 1À64, 2À36 and 5À87% respectively, the latter again being for comparative purposes.
