Title: Improvements in or relating to the delustring of high molecular weight synthetic linear polymers
Inventor: FORD ROGER ANTHONY
IPC: C08K9/02
Filed: 1955-12-06
Abstract: Controlled valency N-semi-conductors are made by introducing into titania, as a substituent ion, not more than 5 per cent by weight of a pentavalent metal of the fifth group of the Periodic Table. Specified fifth group metals are vanadium, niobium, tantalum, antimony and bismuth.  The pentavalent metal may be introduced into the titania by intimately mixing, by wet or dry milling, either the pentavalent metal oxide and titania or heat decomposable salts of the pentavalent metal and titanium; or by co-precipitation from an aqueous solution of a salt of the pentavalent metal and a titanium salt, e.g. with ammonia; the mixture being heated in an oxygen containing atmosphere.  In the example, solutions of potassium niobyl oxalate and potassium titanyl oxalate are mixed and added to aqueous ammonium hydroxide, the resultant precipitate being filtered off, washed, dried, ball-milled and heated in an electric furnace for 18 hours at temperatures up to 850 DEG  C.  Specification 474,999, [Group IV], is referred to.ALSO:High molecular weight synthetic linear polymers are delustred with titania into which has been introduced as a substituent ion not more than 5 per cent by weight of a pentavalent metal of the fifth group of the Periodic Table, namely vanadium, niobium, tantalum, antimony or bismuth, which renders the titania a controlled valency N-semi-conductor.  Specified polymers are polyureas, polyurethanes, polyesters, polytriazoles and polyamides.  The example describes the polymerization of hexamethylene diammonium adipate, in aqueous solution, in the presence of a modified titania prepared from potassium niobyl oxalate and potassium titanyl oxalate.  Specification 474,999, [Group IV], is referred to.

Title: Electrical network automatically responsive to a change in condition
IPC: G08B17/06
Filed: 1957-11-11
Abstract: 866,480. Electric indicating systems; fire alarms. SPECIALTIES DEVELOPMENT CORPORATION. Nov. 11, 1957 [Nov. 23, 1956], No. 35041/57. Classes 40 (1) and 118. [Also in Group XXXVI] A temperature alarm circuit comprises a D.C. bridge with a thermistor in one arm, the unbalance current controlling an alarm relay via transistor amplifiers and including a network sensitive to the rate of change of unbalance current. As shown (Fig. 2) a thermistor 12 and resistor 14 from one branch of a resistance bridge whose other branch is resistors 15, 16. The resistance of the thermistor at ambient temperature is very high, producing an unbalance current which causes transistor 25 to conduct a large current through resistor 27, whereby the voltage at the base of a following transistor 29 is sufficiently low to cut off current through relay 34. When the temperature is high the resistance of thermistor 12 falls, the unbalance current is reversed, current through resistor 27 falls and transistor 29 conducts sufficient current to energize relay 34, and operate an alarm circuit. The circuit changes are strengthened by the fact that when transistor 29 conducts, its output impedance falls, thereby raising the potential at the emitters of both transistors. A rate-sensitive network 20 is included in the unbalance diagonal of the bridge, so that a similar effect is produced at a predetermined rate of change of temperature. Resistor 14 and thermistor 12 also form a bridge with resistors 36, 37, the unbalance diagonal including a temperature-compensating network 38 controlling a second relay 50, which is actuated at a predetermined temperature rise.

Title: Improvements in or relating to stop motions for knitting machines
IPC: D04B35/10
Filed: 1934-12-06
Abstract: 444,128. Knitting-machines. BROOKS, J. F., Baggrave Street, Leicester. Dec. 6, 1934, No. 35065. [Class 74 (ii)] Stop motions.-The failure or abnormal condition of a yarn or yarns fed to a circular knitting machine is used to interrupt, establish, or vary the action of radiant energy on a cell or device sensitive thereto which cell renders operative means for automatically stopping the machine. In the multi-feed machine shown each yarn a passes from a bobbin 11 through a guide 13, over a hook 15 normally held in position by a spring 16a, past a gate 14, and on to the needles. The end 1c of a dropper 1 pivoted in a casing 3 passes through each gate 14 and encircles the yarn a, the other bent end 1b of each dropper being arranged to engage a tooth 2c on a disc 2 and turn the same when the yarn breaks or when, due to excessive tension, it slips off the resilient hook 15, the dropper 1 falling into the position shown in dotted lines in Fig. 4. The disc 2 has a notch which when in register with the slot 19a, allows light from a lamp 17 to reach the selenium cell 18 the current from which is amplified by a valve 24 and transformer 23 and energizes a relay 20 which in turn causes an electromagnet 21 to be energized and through the link 42 turns a rod 41 to operate the stop mechanism. The motion of the disc 2 is limited by a pin 2e and a notch 7a in a plate 7. A light spring 8 and a slightly heavier spring 9 also engage the pin 2e and normally engage a pin 7b fixed in the plate 7 thus bringing the disc 2 to normal position with its notch out of alignment with the slot 19a. When the rod 41 is rotated to stop the machine, it breaks the circuit of the magnet 21 and is returned to normal position again by a spring 42b, but it already has rotated a rod 29 through the lever 38, one-way-acting link 37, and a lever 30. An arm 36 on the top end of the rod 29 engages the pin 2e and returns the disc 2 and any displaced droppers 1 to their original positions. The lever 30 does not return with the rod 41 but is moved by hand after the faulty yarn has been made good.

Abstract: 1,177,711. Making cavity panels; jointing by rolling. OLIN MATHIESON CHEMICAL CORP. 31 July, 1967, No. 35168/67. Headings B3A and B3M. A sheet metal panel with internal cavities, e.g. a heat exchanger is made by bonding two metal sheets together by hot rolling, at least one of the sheets having one surface coated with a stop weld material, placing a nozzle 36 between the sheets and inflating portions of the sheets between dies 24, 26 by fluid pressure. The sheets are preferably an alloy of copper, aluminium, magnesium or steel. The inner surfaces are cleaned by wire brushing, solvent degreasing or etching in acid. The stop weld material may be applied by spraying or painting through a stencil or squeezed through a silk screen. The stop weld is omitted from the marginal edge and a narrow portion 14 of stop weld is provided between the edge of the composite and the interior. Suitable stop welds are graphite and water glass mixture, zinc oxide, kieselguhr, flint, talc powder, cork, clays and mixtures thereof. For sheets of aluminium alloy the composite is heated to 800‹ to 1000‹ F., e.g. 950‹ F., and hot rolled to a 65% reduction. The composite is then cold rolled and annealed. The sheets are prised apart at the area 14 and the nozzle 36 inserted. The dies may have various shapes and cavities of unequal sizes. The degree of bonding may be varied by different types and different thicknesses of stop-weld. The thickness may be reduced by wire brushing to remove part of the stop-weld with extreme accuracy. Certain areas of the composite may be bonded by this method with a weaker bond than other areas. The cavity panel may be used as a heatexchanger, a sheath for an electric cable, or a heating element.

[Also in Group XXI] A method of packing sand into a space beneath a sub-aqueous building in which a mixture of sand and water is pumped into the space and the water only is withdrawn by a suction pipe is characterised in that the pressure and suction pipes reciprocate angularly about a vertical axis. The apparatus comprises a pump 6 feeding a mixture of sand and water from a barge 7 through a pipe 5 to a vertical pipe 4 and thence to an outlet 8. Attached to the pressure pipe is a suction pipe 9 in which is a compressed air driven pump 10. The suction pipe discharges into a filter-box (not shown) so that the amount of sand withdrawn can be seen. The pipes are carried by a frame 13 running along the top of the building 3 and are mounted to swing about the axis of the vertical branch and deposit sand in an arc. In operation the pipes oscillate continuously and the frame moves either intermittently or continuously along the building, the rate of movement being adjusted to ensure adequate deposition of sand, an increase in the amount of sand reaching the filter-box indicating that the space is full.
