The solid bodies forming cords for the liquid particles may be of glass ceramic metal or a polymer. The chromatographic material may be silica, alumina, titania, zirconia, a silicate or a polymer; or a precursor such as a solution of sodium silicate or aluminium sulphate, or a polymerisable monomer. Conversion to solid form may be by inclusion of a gelling agent, by freezing or by polymerisation. When packed in a steel column and treated with # #' oxydipropionitrile good chromatographic separations of phenols are obtained.

Abstract: 1,126,088. Electron multipliers; image intensifier tubes. BENDIX CORP. 3 Nov., 1966 [10 Nov., 1965], No. 49285/66. Heading H1D. In an electron multiplier of the resistive channel type and which may be incorporated in a channel type image intensifier tube, two channels 23, 25, each with a potential gradient along it set up by voltage sources 30, 32, are arranged in series but inclined with respect to one another, as shown, so that the effects of ion feedback from the output end to the input end of the multiplier are reduced. An image intensifier tube may have two, three or more multiplier channel arrays and one voltage source may be used for all arrays. The arrays are preferably separated from each other by a distance equal to the channel diameter in order to minimize moire pattern beating effects. The arrays may be at different potentials and the voltage between adjacent arrays may be reversed to interrupt operation.

The pH may be adjusted with NaOH, H 2 SO 4  or HCl. The precipitation may be effected batchwise or continuously, preferably using an excess of the heavy metal salt in aqueous solution. Preferably an iron salt is used with simultaneous or subsequent addition of a copper salt. Thereafter a flocculating agent (e.g. polyacrylamide) may be added, and the precipitate removed by centrifuging or filtration or by settling in one or more series-connected tanks. Thereafter heavy metal ions may be removed from the effluent, e.g. by adding NaOH or Ca(OH) 2  to obtain a pH of 10- 12 thereby precipitating iron as its hydroxide.

Abstract: 1,190,879. Collagen. CENTRE TECHNIQUE DU CUIR. 25 Oct., 1968 [1 Dec., 1967], No. 50813/68. Heading C3H. A process for the preparation and conditioning of proteinic pastes, dispersions and gels of animal origin comprises effecting on the previously ground fibrous raw material a mechanical action by malaxation or otherwise, treating this raw material simultaneously with malaxation by means of an acid chemical agent comprising a chlorinated organic acid, the temperature of treatment not exceeding 32‹ C., diluting the so-obtained paste either with water, adjusting the acid content between 0À01 and 0À1M and the pH between 2À5 and 4À5, or with a dilute acid solution of which the concentration and pH have been previously adjusted to these values, the temperature never exceeding 32‹ C. The raw material may be skins. Acids exemplified are chloracetic, chloropropionic, dichloracetic and trichloracetic acids. A prior treatment to reduce the molecular weight by splitting some of the proteins to peptides may comprise the use of alkali or of an enzyme which attacks keratin and elastin but has little effect on collagen, or the use of a lyotropic agent such as calcium, barium, strontium, magnesium, zinc or lithium chloride or lithium bromide.

Abstract: 1,014,702. Latches. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 24, 1963 [Dec. 27, 1962], No. 50950/63. Heading E2A. A locking device comprises a resilient strip 12 extending along one side of a supporting member 10 and secured thereto by a rivet 13 and a tapered bolt 12b attached to and extending transversely of the resilient strip and movable through an aperture 11 in the supporting member, the bolt being urged by the resilient strip into a locking position in which it projects from the other side of the supporting member, and the converging boundaries 12c, 12d of the bolt fitting with clearance between guides provided on the supporting member. To remove an object e.g. part 14 of a lighting fitting from the locked position, the strip is turned through a small angle about the rivet by pressure over the part 14 until the edge 12d of the bolt slides along the edge 11b of the aperture, thus twisting the bolt inside the supporting member. An object is inserted in a similar way but the bolt is forced back by the object sliding up the edge 12d of the bolt. In another embodiment Figs. 5 and 8 (not shown) the bolt is tapered symmetrically so that it requires an equal force to insert or remove an object and flanges of the supporting member act as guides for the upper and lower edges of the bolt.

Title: Apparatus for testing electrical switches
Inventor: BRADER KENNETH K
IPC: G01R31/327
Filed: 1964-12-16
Abstract: 1,080,500. Discharge tube relay operating circuits. WESTERN ELECTRIC CO. Inc. Dec. 16, 1964 [Dec. 17, 1963], No. 51129/64. Heading H3P. [Also in Division G1] A number of relays or reed switches 10, are simultaneously tested by connecting their contacts in series and passing a predetermined current through them, and then connecting them in parallel and sensing a characteristic to determine the effect of the current. The test cycle is performed by means of a multi-cathode gas tube 34 in which under rest conditions the discharge is to cathode B1. Actuating start button 31 energizes winding 28a on a magnetically latching relay 28 to close contact 28-1. The next pulse from generator 41 now steps the discharge to cathode K1, and magnetic latching relay 14 is energized over winding 14a to close contact 14-1 completing the circuit to energizing coils 13 of switches 10. Further pulses from generator 41 steps the discharge on to cathode K2 energizing magnetic latching relay 17 over winding 17a and contact 17-1 closes to connect the supply 16 to the series-connected switches 10. Further pulses step the discharge until it reaches cathode K5 where relay 17 is released by the current in winding 17b When the discharge reaches cathode K6, relay 14 is released via winding 14b, contact 14-1 opens allowing switches 10 to open and contact 14-2 closes energizing relays 19 . . . 24 which connect the switches 10 in parallel via contacts 19-1 to 24-1. When the discharge steps on to cathode 9 magnetic latching relay 27 is actuated closing contact 27-1. If due to a fault one of the contacts 10 fails to open an energizing path for winding 28b is completed through the faulty switch, and relay 28 releases. If there is no fault relay 28 remains energized. The discharge is then stepped on to cathode K10 releasing relay 27 and then back to cathode B1. The cycle either terminates at this point or repeats depending on whether relay 28 has been released by a fault or remains energized. Manual stopping of the cycle may be effected by releasing relay 28 by means of button 33. During a test, the contact resistance of each switch 10 may be measured by actuating switch 32 to the " CONTACT RESISTANCE " position in which the switches 10 are in series across the supply. The two contacts of each switch are taken to a pair of contacts on selector switch 46 (only one pair are shown connected) and may be thus selectively connected to an indicator 47 indicating the contact resistance.

The inlet duct 3 shown is formed of rubber or other elastomeric material so that it can have resilient movement relatively to the or each rotary cutting edge, but instead it may be of metal and resiliently connected to the housing. Alternatively, the housing or rotor may be carried on resilient mountings. The inlet duct 3 is clamped in an axially adjustable manner between a boss 2 and a metal sleeve 7 by a number of bolts 12. The outlet end of the inlet duct 3 may have one or more flexible steel cutting knives which cooperate with the rotary cutting edge or edges.
