Title: Improvements in or relating to the Testing of the Properties of Fluid Suspensions Containing Magnetic Particles
Inventor: PEARCE RALPH REGINALD
IPC: G01R33/12
Filed: 1966-08-11
Abstract: 1,190,927. Testing magnetic properties. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 10, 1967 [Aug.11, 1966], No.35929/66. Heading G1N. To test a fluid suspension containing acicular magnetic particles used in the manufacture of magnetic recording tape, a sample of the suspension is coated on to a moving tape and is subjected to an orientating magnetic field to produce discrete regions of orientated particles on the tape which are then, while the coating is still fluid, subjected to a disorientating magnetic field in the opposite direction, the magnitude of which is varied until no remanence is detected by a detector head 12, the value of the disorientating field then being read from meter 16. The measurement process may be entirely automatic. The suspension may be applied only to the centre of the tape and the capstan 3 may have a cut away channel in the middle of its traction surface. The suspension may be applied in a series of discrete bands, Fig. 3 (not shown), in which case the orientating magnetic field may be produced by a permanent magnet (25). The invention may be used to measure the rheological properties of paint by adding a small proportion of magnetic particles to the paint.

Title: Antifibrinolytically active isomer of 4-aminomethyl-cyclohexane carboxylic acid
IPC: A61K31/195
Filed: 1964-12-16
Abstract: The invention comprises a 4-aminomethylcyclohexanecarboxylic acid isomer in substantially pure state assaying at least about 90% antifibrinolytically active material (and defined also by its electrophoresis characteristics), and the preparation thereof by the following processes: (1) synthesis from the appropriate isomer of a cyclohexane compound having in the 4-position an aminomethyl group or a substituent and in the 1-position a carboxylic acid group or a substituent convertible thereto (but excluding 4 - aminomethylcyclohexanecarboxylic acid itself), by converting the former and/or the latter substituent(s) to the desired final substituent(s); (2) isomerization of the inactive isomer by heating it, alone or in admixture with active isomer, in a compatible liquid vehicle in which an alkali metal carboxylate of the active isomer is soluble, together with a sufficient amount of an alkali metal alcoholate derived from a C1- 24 alkanol, benzyl alcohol or furfuryl alcohol, or an alkali metal hydride, hydroxide or amide, for a time sufficient to form the alkali metal salt of the active isomer, separating this and converting it to the free acid by passing a solution thereof in an aqueous solvent through a bed of a cation exchange substance. Examples given for process (1) are: (a) dimethyl cyclohexane-1,4-dicarboxylate --> mono-ester --> mono-ester acid halide --> mono-ester amide methyl 4-cyanocyclohexanecarboxylate --> 4-cyanocyclohexanecarboxylic acid --> 4-aminomethylcyclohexanecarboxylic acid; (b) 4-aminomethylcyclohexanemethanol --> 4 - benzoylaminomethylcyclohexanemethanol --> 4-benzoylaminocyclohexanecarboxylic acid --> aminomethylcyclohexanecarboxylic acid.  If either of these processes is carried out with the other isomer of the starting material, it yields a suitable starting material for process (2), in which alternatively there may advantageously be used the isomeric mixture obtained by catalytic hydrogenation of a benzoic acid having in the 4-position an aminomethyl group or a substituent convertible thereto. Pharmaceutical preparations (e.g. tablets, capsules, elixirs and injection solutions) comprise the isomer of the invention in association with at least one pharmaceutically acceptable carrier.

Title: Nuclear reactor fuel element assemblies
Inventor: OBERTELLI JOHN DAVID
IPC: G21C3/33
Filed: 1965-08-23
Abstract: 1,105,289. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 10 Aug., 1966 [23 Aug., 1965], No. 36176/65. Heading G6C. A fuel assembly for a nuclear reactor, wherein steam is generated from water boiled by heat exchange with fuel elements, comprises a cluster of end supported, spaced fuel elements with transverse bracing grids, at least one of the grids having coolant flow deflecting vanes disposed and shaped for extracting liquid phase coolant entrained in vapour phase coolant and directing it into contact with selected regions of fuel element surfaces. Each grid comprises a group of ferrules contained within a peripheral rim, each ferrule encircling a fuel element. The deflecting vanes may be arranged in a first group which directs coolant flow towards the radially outer fuel elements of the cluster and a second group which extracts the liquid phase coolant and directs it into contact with selected regions of the radially outer fuel element surfaces which are most susceptible to " burn-out ". The vanes, which are on the sides of the grid facing the coolant flow, are of divergent form so as to present a " prow "-like profile to the coolant. In an alterntive construction, the vanes are on the opposite side of the grid and are profiled to " scoop " coolant after it has passed through the grid, while in a further construction vanes of the two types are both present. In a still further construction, the vanes are of cruciform section and are twisted about their axes, being located in interspaces in the grid bounded by adjacent ferrules to impart swirl to coolant flowing through the interspaces. The fuel assembly may be used in a steam generating, heavy water moderated reactor comprising a moderater tank penetrated by open ended tubes through which extend pressure tubes each housing a fuel assembly. Each fuel assembly is suspended from a closure plug for the corresponding pressure tube by a tie member which includes a neutron shield plug. The tank is bounded by neutron shield tanks containing light water.

Title: Improvements in or relating to impulse transmitters for electric remote control systems
IPC: G08C19/18
Filed: 1934-12-22
Abstract: 440,063. Distant control systems. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Dec. 22, 1934, No. 36869. Convention date, Jan. 13. [Class 40 (i)] The impulse transmitter of a remote control system comprises a motor-driven interrupter 15 arranged to transmit impulses over the line wires 18, the number of impulses transmitted being determined by the selective operation of one of the relays A1-A5 to mark the bank contacts of a stepping switch C also driven by the interrupter. The selected relay is operated by a corresponding push-button switch over a circuit including the normal contact and wiper .25 of switch C, locks up over contacts of relay B, marks the appropriate contact of the switch C and starts up the motor D of the interrupter 15. Impulses are then transmitted over line wires 18 and switch C is stepped by magnet 20 until wiper 25 engages the marked contact and relay B is energized to release the selected relay and thereby terminate transmission. When the arm 25 is moved, off-normal contacts 33 are closed to start up a resetting motor 31 which drives a disc having a projection adapted to co-operate with a pin on the ratchet wheel and thereby restore the wheel to normal.

Title: Improvements in counting devices
IPC: G06M1/10
Filed: 1955-12-23
Abstract: 816,222. Counting-apparatus; statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1955 [Dec. 30,1954], No. 36930/55. Class 106 (1). A counting-apparatus comprises a plurality of bi-stable devices arranged to assume characteristic combinations of states, in which the combination representing any digit registered therein differs from that representing the complementary digit by the state of one particular device only, so that the digit registered may be changed to its complement by changing the state of said one device. In the first example a decimal counter comprises five relays 11-15, Fig. 1A, each having a latch and drop coils L and D respectively and being arranged in two parallel chains 15L, 11L, 13L, 13D, 11D and 15D, 12L, 14L, 14D, 12D. The entry to the counter is from punched cards and the programme determines whether a digit is to be entered into the counter in its true or complement form. If the digit is to be entered in its true form impulses are passed to the counting chain from the instant of sensing a hole until the tenth point,of a card cycle. Impulses one, two ... nine cause energization of the relay coils in the following sequency 11L, 12L, 13L, 14L, 15L, 14D, 13D, 12D, 11D and the coils 18L, 18D of a control relay are alternately energized to direct alternate impulses to the appropriate chain. If the digit is to be entered in its complementary form impulses are passed to the counting chain from the beginning of a card cycle until a hole is sensed: It can be seen from the above sequence of operation of the relay coils that the registration of a particular digit differs from the registration of its complement merely by the state of relay 15 so that conversion of a digit to its complement is effected by changing the state of relay 15. Transfer.-At point thirteen of a card cycle an impulse is admitted to the counting chains if the chains of the next lower order have passed through the registration " 9 to " 0." Read-out.-During a read-out cams 9-0, Fig. 1, generate impulses through points one ... ten of a card cycle. The state of a relay 25 determines whether the digit is to be read out in its true or complement form and the state of relay contacts 11d, 12d, 13d, 14d, 14e, 13e, 12e, 11e determine the number of impulses transmitted to the. read-out means. Zeroizing is effected by transmitting impulses until the relays 11-15 register zero. In another example six relays 71-76, Fig. 3A, are used, the coils 71L, 73L, 75L, 75D, 73D, 71D and 76L, 72L, 74L, 74D, 72D, 76D being disposed in two parallel chains as shown. This counter operates in the base twelve but by selectively shorting out relay 75, relays 74 and 75 or relays 71 to 75 the base can be altered to ten, eight or two. Transfer and reading out are effected as described above but zeroizing is effected by instantaneously setting the relays 71-76 to register zero.
