Title: Purification of blood
IPC: C07K14/02
Filed: 1973-07-09
Abstract: 1430461 Purification of blood RESEARCH CORP 9 July 1973 [13 July 1972 11 June 1973] 32587/73 Heading A5B A method of removing serum hepatitis antigen (HAA) from blood fluids comprises (1) coupling serum hepatitis antibody to a support phase comprising carbohydrate groups to form an antibody support phase complex (BHAB) and (2) agitating BHAB with the fluid to be treated to form a complex with the antigen and (3) separating the antigen-BHAB complex from the fluid. The support phase is preferably agarose or a cellulosic material. The support phase may be activated with cyanogen bromide for coupling with the antibody. The BHAB is agitated with the fluid preferably at a temperature between 0‹C and 45‹C. Pure HAA may be produced by reacting the HAABHAB complex separated in step (3) with (a) an aqueous alkali solution having a pH in the range of 9 to 12 or (b) an aqueous solution of glycine acid salt having a pH between 2.5 and 4, and separating, e.g. by ultrafiltration, the HAA from the aqueous solution. The BHAB may be washed with neutral saline solution and subsequently with a buffer of pH between 7 and 8 and then recycled for further use. The fluid is preferably blood plasma and the method is particularly applicable to determine HAA content by radioimmunoassay techniques.

Title: Interrupter for instance for metal vapour apparatus ignited by high tension impulses
IPC: H01H29/24
Filed: 1921-12-12
Abstract: 172,661. Pole, J. C. Dec. 11, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Mercury switches; arc - rupturing devices.--A mercuryvapour lamp is connected to directcurrent mains in series with an inductance 4 and resistance 5. A plurality of series - connected mercury current interrupters 6, 7 are connected in series with a current-limiting resistance 12 across the terminals 2, 3 of the lamp 1. The interrupters 6, 7 are arranged to be tilted simultaneously either by hand or by electromagnetic means, thereby interrupting the current through the shunt circuit 5, 4, 12, 8, 9, 10, 11. The rise in voltage consequent on the interruption of the magnetizing current of the inductance 4 produces a high-tension impulse across the lamp 1, which is thereby ignited. Electromagnetic means for tilting the mercury interrupters are shown in Figs. 2 and 3, the mercury containers 6, 7 being secured in a carrier 15, 16 pivoted between horizontal pivots 17, 18. An armature 14 is attached at one end to the frame 15, 16 and is arranged between the poles 13<a>, 13<b> of an electromagnet 19 with exciting windings 4a, 4b. When the supply switch is closed the coils 4<a>, 4<b> are energized and the armature 14 is attracted, thereby tilting the mercury vessels 6, 7 and interrupting the magnetizing current of the inductance 4.

Abstract: 1,201,110. Light-sensitive multi-layer colour photographic element. FUJI SHASHIN FILMK.K. July 12, 1968 [July 18, 1967], No.33491/68. Heading G2C. [Also in Division C2] A multi-colour photographic element has on a support, at least 1) a red-sensitive silver halide emulsion layer containing as a cyanforming coupler a phenol derivative or an α- naphthol derivative, having at the para-position to the hydroxyl group thereof an iodine or a bromine atom, 2) a green-sensitive couplercontaining emulsion layer, 3) a blue-sensitive coupler-containing emulsion layer, and 4) an intermediate layer containing silver halide grains of photo-sensitivity such that they are not reduced in subsequent photographic development and positioned between the red-sensitive layer and the green-sensitive and/or the blue-sensitive layer. The intermediate layer traps the migrating bromide and iodide ions, released by the cyanforming coupler by its reaction with the oxidation product of an aromatic primary amine developing agent, thereby preventing the latter ions inhibiting development in the other layers. The silver halide incorporated in the intermediate layer may be silver chloride, silver bromide, silver chloro-bromide or silver iodobromide and the amount is usually between 1 x 10<SP>-6</SP> and 1 x 10<SP>-4</SP> moles per 100 sq.cm. of the colour photographic element.

Abstract: 1,056,761. Making bags; seaming nonmetallic sheet material. TRANS-ATLAS A.G. Aug. 23, 1963 [Aug. 23, 1962], No. 33512/63. Headings B5D and B5K. [Also in Division B6] Carriers 15, Fig. 1, which grip, seal, and cut into bags a tube or longitudinally folded web are separate from the belt 19 which drives them whilst they grip the tube or web, so that their distance apart, which determines the size of the bags made, and the speed of the belt 19, which affects the rate of production, can be varied independently. Feeding webs and adjusting bag size.-Carriers 15 fed into tracks 11, 11<SP>1</SP>, Fig. 1, by wheels 29, 29<SP>1</SP> grip between them driving belts 19 and the web so that they are driven by the belts and carry the web along with them. The carriers return via inclined tracks 12, 12<SP>1</SP>. Swingable gates 32, 32<SP>1</SP>, Fig. 3, opened by a face cam 37, control feed of the carriers by wheels 29, 29<SP>1</SP> which are spring coupled to their driving shafts to allow for any discrepancy in their synchronization with cam 37. The ratio of the speeds of wheels 29, 29<SP>1</SP> and belts 19 determines the distance between consecutive pairs of carriers and hence the size of bags produced. The ratio is varied by a gear (not shown) and a further gear controls the speed of belts 19 whilst the ratio remains constant. When a printed web is used a photo-electric cell 63 (Fig. 5, not shown), controls further the speed of belts 19 via a known amplifier and differential 59 (Fig. 5) so that the cutting and sealing operations are performed by the carriers at the correct positions on the web. Cutting and sealing.-One or two shielded filaments 65 (Fig. 7), in each carrier 15, 15<SP>1</SP>, heated by current picked up from a contact rail by a brush (not shown), seal the web transversely at one or two places, the length of sealing time being controlled by the length of the contact rail. Each upper carrier 151 has a knife 70 carried by a pin 69 which slides in a slot 68 extending longitudinally of the carrier (i.e. across the web) and as the carrier advances through the machine fixed camming ploughs engage the pin so that the knife is pushed across the web to cut it and then returned to its original position. Stacking of completed bags.-A pair of wings 79, Fig. 8, freely rotatable on a shaft 78 lies in a position of rest shown in dashed lines. An approaching pair of carriers 15 swings one of the wings 79 into contact with the bag 90 which it carries, and causes the wing to force the trailing edge of the bag free from the carriers and on to a belt 84. Simultaneously, the leading edge of the bag is released from the previous pair of carriers and also falls on to the belt. When a predetermined number of bags have been deposited a counter 91 energizes an electromagnetic coupling 88 so that the belt 84 is moved to deposit the stack of bags on a table 92.

A high-pressure lubricant gun has a piston 12 driven by a motor, which forces lubricant from the cylinder 14 through an outlet 21, there being a pressure-limiting valve 3 provided in the lubricant path which is connected with the lubricant container 19 by a return passage 28. The motor drives an eccentric shaft 6 through a pinion 4 and a gear-wheel 5, which operates a crank 7 through a bearing 10. The crank abuts the plunger 12 thereby compressing lubricant contained in the cylinder. Lubricant is forced out of the cylinder via a non-return valve 15. The pressure limiting valve 3 may be adjusted by means of a screw 27. When the valve 3 opens, lubricant returns to the container 19 via the passage 28. The quantity of lubricant supplied may be regulated by means of a valve 40 (Fig. 6, not shown).
