Title: A generator for the production of mechanical foam
IPC: B05B7/00
Filed: 1960-07-12
Abstract: 881,320. Foam generators. ROTVAND, L. July 12, 1960 [April 7, 1960], No. 24255/60. Class 14(1). Mechanical foam is produced in a generator comprising a mixing tube 1 of substantially constant crosssection into which water under pressure from a tube 2 and emulsifying agent from a tube 5 are introduced by a centrally disposed injection nozzle 3, air suction ports 6 being provided in the tube 1 immediately downstream of the nozzle 3 and a small converging pipe 9 being mounted inside the tube 1 coaxially supported by radial blades 10 at a position downstream of the nozzle 3. The arrangement is such that the pipe 9 is positioned in a zone of the tube 1 in which the cross-section of the tube is entirely filled with foam formation and the pipe 9 speeds up the central part of the foam jet passing through the pipe 9 and slows down the peripheral part of the jet passing between the pipe 9 and tube 1. This increases the flow turbulence and improves the quality of the foam. Near the outlet of the tube 1 a second divergent. pipe 12 is centrally disposed to restore similar speeds to the central and peripheral parts of the foam jet before projection from the outlet 14. The injection nozzle 3 has a number of small inwardly directed points or projections 8 designed to produce atomisation of the outer surface layers of the jet issuing from the nozzle 3.

Title: Manufacture of specific vaccines
IPC: A61K39/02
Filed: 1920-08-21
Abstract: 150,334. Elektro-Osmose Akt.-Ges., (Graf Schwerin Ges.). Aug. 23, 1919, [Convention date]. Addition to 150,328. Vaccines and immunizing serums.-Specific vaccines prepared by the action of an electric current on suspensions of bacteria as described in the parent Specification are stabilized by the addition of a. protective colloid. The added colloid may be derived from immune blood serum corresponding to the particular bacteria employed so that the resulting vaccines confer passive immunity in addition to the active immunity. The colloid added is preferably a completely soluble proteid such as pseudo-globulin and albumen. In examples, normal blood serum, or immune serum is mixed with bacilli separated from a culture medium or with the whole bouillon culture and placed in the centre compartment of u three-cell electro-osmotic apparatus divided by electrodes and diaphragms, and current is passed for several hours, salt solution being added as required to maintain the conductivity. After the required period the passage of current is continued to eliminate the electrolyte and to cause the separation of euglobulin. The clear solution to be used as a vaccine is separated from the deposit of euglobulin and insoluble bacteria residue in a centrifugal apparatus. In some cases the separated deposit is dissolved in water containing electrolytes and feebly alkaline, and is diluted to form a vaccine to be used alone or mixed with the original clear solution. The bacteria specified are those of swine erysipelas and chicken cholera, and streptococci, pneumococci, and meningococci.

Filed: 1974-05-31
Abstract: 1451572 Borehole logging TEXACO DEVELOPMENT CORP 31 May 1974 [5 June 1973 15 Feb 1974] 24359/74 Heading G1A In borehole logging, coal beds and oil shale zones are located by measurement of the carbon/oxygen ratio of the formation obtained by irradiating the formation with short bursts of fast neutrons and measurement of gamma radiation resulting from the inelastic scattering of these fast neutrons during the neutron bursts. The sonde of Fig. 1 comprises a deuteriumtritum reaction neutron generator 11 pulsed on for 5 Ásecs at 50 to 200 Ásec: intervals. The output of detector, a NaI or CsI (thallium-doped) crystal 10 coupled to a photo-multiplier 12 shielded by boron from thermal neutrons and by shield 13 of paraffin, carbon, iron, lead or steel from source 11 is gated during the source pulses so as to avoid detection of the neutron capture γ-ray population. Scintillator produced background is discriminated by discriminator 18. The pulse height analyzer 24 selects pulses in the windows shown in Fig. 3. Besides the C/O ratio, C + O and Ca/Si are also recorded at 30. For coal evaluation C/O is indicative of coal quality and oil shales are identified on the basis of their kerogen content. Further logs using a different design of probe may be taken to aid identification of the above mentioned zones and include a gamma ray density log and a Hydrogen index log. Reference has been directed by the Comptroller to Specification 1364572.

Title: Improvement in guns for administering tablets to animals
IPC: A61D7/00
Filed: 1951-10-19
Abstract: 696,796. Veterinary appliances. BECK, R. C. Oct. 19, 1951 [Oct. 24, 1950], No. 24417/51. Class 81 (ii). A gun for administering tablets to animals comprises an actuating plunger working in a barrel and a tube, at an angle to the barrel, serving as a magazine for the tablets and from which they drop singly by gravity. In the preferred form the plunger 15 is actuated in the barrel 1 to expel the tablets 17 by manual compression of a pivoted lever 7 against the handle 3. When the plunger reaches its forward position, a recess 25 aligns with a stud 24 which, in moving radially inward, allows a spring arm 21 to move towards the barrel and permit the passage down the tube 16 of a further tablet 17 which, on retraction of the plunger, drops into the barrel behind the preceding tablet. A hinged trap 28 prevents the reserve tablets dropping out of the tube 16 and a rubber tip 30 prevents tablets leaving the barrel except when forced out by the plunger. The Specification also describes the use of a clip, instead of the projection 19, for holding the tablets and a spring lever in place of the spring arm 21. It is also proposed to actuate such a spring lever by a pin fixed to the lever 7 and projecting through the plunger 15.

Abstract: 861,205. Sorting solid materials. EWEMASKINER A.B. July 17, 1959 [July 22, 1958], No. 24700/59. Class 117 Pieces of timber are sorted according to length by being conveyed transversely with their one ends in line, so that spaced members in their path are actuated in dependence upon the said lengths, and the pieces are delivered to various collecting compartments, and the pieces in each compartment are then further sorted according to length after adjusting the position of the spaced members. Pieces of timber 1 are fed to a conveyer 3 which delivers them to a conveyer 5 along the path of which discharge places 6-9 are arranged, and arms 10-12 respectively are associated with the discharge places and are actuated by members 13-15 respectively. As shown in Fig. 2 the one ends of the pieces 1<SP>1</SP>, 1<SP>11</SP> are aligned, and each member 13-15 is adjustable to take up a position corresponding to the shortest length of a piece it will allow to pass the respective discharge place. Thus if a piece is sufficiently long to strike member 13, the arm 10 is moved into contact with the conveyer 5 and the piece fed to cullector rails 20 and compartment 16. Pieces of shorter length are fed to the other collecting stations along the lower run of the conveyer, and if a piece is of sufficient length to strike one of the members 14 or 15, an arm 11 or 12 will be raised and the piece removed through discharge place 7 or 8 to collector rails 21 or 22 and compartments 17 or 18. The shortest lengths pass to rails 23 and compartment 19. The pieces in each compartment are then further sorted to provide, for example, groups of timber pieces varying in length by 1 foot, after adjusting the positions of the actuating members.

Patent GB-602899-A (GB)
Title: Improvements in process of degassing liquids
IPC: B01D19/00
Filed: 1945-09-25
Abstract: In degassing liquids by contact with solid bodies, bodies of small size are held in suspension in an ascending current of the liquid to be degassed.  The solid bodies may comprise grains of different sizes, the liquid being first contacted with the largest grains and subsequently with grains of gradually smaller size. The temperature is preferably between the boiling temperature of the liquid and the temperature at which the liquid is to be subsequently treated and may be gradually increased as the degassing progresses.  As shown, liquid to be degassed enters a spherical container heated at the bottom through an immersed pipe and passes up through a suspended granular or pulverulent material such as ground limestone or brick, or iron shavings.  Gas escapes from the top of the vessel, while liquid is discharged through a lateral outlet pipe.  Alternatively, liquid is introduced at the bottom of a cylindrical, conical, or cylindroconical column containing the degassing material and surrounded by a beating jacket.  Degassed liquid from the top of the column or after subsequent operations may be heated and used as the heating liquid and independent beating may also be used.  In both modifications, the grains may be arranged so that the liquid passes over particles of decreasing size which are restrained from loss by the use of receptacles in the shape of inverted cones.  In another modification, a part of the degassed liquid may be recirculated or any other liquid added to the ingoing liquid.  The degassing of boiler feed-water is referred to, in which lime is used to eliminate dissolved carbon dioxide and the precipitated calcium carbonate grains used as the degassing material.
