Abstract: 1512052 Detection of antibodies PHARMACIA DIAGNOSTICS AB 19 May 1975 [29 May 1974] 21170/75 Heading G1B [Also in Division C3] Antibodies in an aqueous sample are detailed by a method wherein the sample is contacted with a smooth surface coated with adsorbed or chemically bound antigen and antibody thus bound to the surface is detected by reaction with a biopolymer itself bound to small water insoluble particles, the formation of a coating of the biopolymer-bound particles being visible to the eye. The water-insoluble particles may be staphylococci and the biopolymer protein A, for use for example in detecting anti-dextran antibodies reacted with dextran on a glass slide, antibovine senna albumin (BSA) reacted with BSA in a thin layer chromatographic method test, or anti-dextran antibodies reacted with a dextran - anti-dextran mixture, or alternatively the particles may be guinea pig anti-rabbit immunoglobulintreated polymethylmethacrylate particles for use in detecting rabbit anti-dextran antibody bound to dextran on a glass slide.

Title: Improvements in rotary type of brick and briquetting presses
IPC: B30B11/12
Filed: 1921-08-09
Abstract: 167,768. Singh, D. Aug. 14, 1920, [Convention date]. Cylinder machines.- In a rotary cylinder moulding-machine of the type in which the stock is fed into radial moulds, and compressed between sets of inner and outer plungers, the primary and nnishing outer plungers 22, 23 are carried in a frame 38 which is oscillated in stages by cams 58, and is automatically interlocked with the cylinder 10 during its movement in one direction. The inner plungers are actuated by an eccentric 15, and the outer plungers are caused to remain during the compression in alignment with their respective moulds by the action of spring plungers 41. The latter are freely linked to the fixed framework and are mounted on the extension 39 of the oscillating frame 38 so as to engage successively the mould orifices and impart the required motion to the plungers 22, 23; the latter are mounted on the frame 38 in guide-horns 37 and sleeve frames 48 respectively, the necessary pressure being obtained by links 34, 46 pivoted on the crank 30. Disengagement of the dies is caused by the outward movement of the sleeves 48 operated by eccentrics 50 on the shaft 51 through connecting-rods 49. The drum 10 is driven by pinion gearing from the main shaft 51, and itself drives the shaft 57 on which the cams 58 are mounted, the cam lifts and the gearing being arranged according to the number of mould boxes in the drum. The compressed blocks are finally discharged on to the take-off belt 24 by further action of the inner plungers 13.
Patent GB-221521-A (GB)
Title: Process of washing materials particularly wool, silk, soiled fabrics and the like
IPC: D01C3/00
Filed: 1924-09-08
Abstract: Wools, silk, soiled fabrics, and other fibrous materials are washed and cleaned by any suitable detersive agent in a plurality of vats containing different baths or in a single vat traversed by successively cleaner scouring liquors, the washing power of the detersive agent being increased and its adsorption being diminished by reducing the duration of its contact with the impurities, the reduction of the duration of contact and the recovery for re-use of a part of the detersive agent being effected by centrifuging continuously the liquors of one vat.  The liquors of the other vats may if desired be centrifuged continuously or intermittently.  The efficiency of the process may be increased by the action of an electric current to modify the charges of the suspended particles, and by the introduction of air while the material is propelled by fork conveyers through the bath.  To increase the rate of circulation of the liquors, the vats are made as small as possible, the spaces below their false bottoms having inclined walls.  The mud settling in the false bottoms is removed by flushing.  Before centrifuging, the liquors may be passed through a fibre-collecting device, and the centrifuging may be effected in two stages, a centrifugal mud remover removing the dense sludge, the grease then being removed by a high-speed centrifugal grease separator, and the purified liquor being returned to its respective vat.  The invention may be applied to the process described in Specification 240,482 in which the material is treated with a suint bath followed by a soap bath.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also a process for treating fibrous materials with suint obtained from raw wools, the suint being purified for re-use by centrifuging the liquors.  The concentration of the suint liquor is maintained at about 4 DEG  B<\>ae, and if it becomes too strong, the wools containing most suint may be freed partially therefrom before entering the vat, and their suint may be kept in reserve for treating wool having no suint, the reserve liquor being treated with an anti-putrifactive agent such as thymol, chloroform, potassium cyanide &c. in the proportion of 1.10000.  A process for washing is also described in which the material is treated with soap solutions, liquor from the last vat or pure water being added to the first vat to maintain its level.  This subject-matter does not appear in the Specification as accepted.

Abstract: 998,413. Impedance networks. GENERAL PRECISION Inc. June 13, 1961 [June 13, 1960], No. 21285/61. Heading H3U. [Also in Divisions G4 and H1] A phase-shifting network comprises a bridge circuit including magnetically variable resistor 69.

Title: Monitoring system
IPC: G05D21/00
Filed: 1972-05-08
Abstract: 1393122 Electric selective signalling WESTINGHOUSE ELECTRIC CORP 8 May 1972 [1 June 1971] 21293/72 Heading G4H An environmental data system wherein information in sensors 12-16 is continuously monitored and recorded on magnetic tape 42 in a field station also incorporates means for monitoring each sensor output over a preselected timing interval and for comparing it with a preset threshold value so as to determine when safe pollution levels have been exceeded. The tape 42 is collected every 36 days and sent to a central station; meanwhile, the sensor outputs are fed to counters 44-48 whose counts are fed at the end of each timing interval to latches 52-58 under the control of a circuit 62. The counts are subsequently passed through gates 116 and a shift register 118 to a modem 96 from which a telephone link extends to a modem 98 in the central station; when data is to be transmitted thereto, modem 96 signals a control circuit 108, Fig. 2 (not shown) which outputs a pulse 112 to enable gates 116, then further pulses 114 to shift the data out of register 118. The output from, e.g. counter 44 is fed to a threshold circuit 68; if the threshold level is exceeded, circuit 68 sets a flip-flop 67, whose output is passed as an alarm signal through a gate 73 at the end of a timing interval into an alarm storage circuit 93, Fig. 4 (not shown). If the field station is being monitored, circuit 93 stores the alarm signal; if not, it passes it to an auto call unit 94 which actuates modem 96. When gates 116 are enabled, sensor and field station indentification codes are added to the data, and if the threshold value is exceeded the alarm signal causes an alarm identification signal to be added as well. Sensors 12-16 may measure air and water pollutants, rainfall, wind direction and velocity, sunlight, humidity, barometric pressure, solar radiation, soil or water temperature, &c. The data link may be by means of radio, microwaves or power lines, and the data is recorded in the central station on magnetic tape or punched cards for use in a computer. Control circuit 108 is claimed in Specification 1,393,121.

Title: Method of manufacturing polyvinyl alcohol having carbonyl groups at the chain ends
IPC: C08F8/00
Filed: 1959-06-22
Abstract: Polyvinyl alcohol having terminal carbonyl groups is made by cleaving polyvinyl alcohol having some carbonyl groups in the molecule by reaction with an alkaline liquid.  The carbonyl groups are introduced into the polyvinyl alcohol by oxidation, e.g. with ammonium persulphate, bleaching powder, bromo-succinimide or by photo-oxidation in the presence of a photosensitizer or by irradiation.  Prior to the alkaline treatment, the oxidized polyvinyl alcohol may be subjected to treatment with a dilute acid such as hydrochloric, sulphuric, formic, chloroacetic or benzenesulphonic acids.  The cleavage with alkali is preferably conducted at 90 DEG -100 DEG C., under an atmosphere of nitrogen.
