Abstract: 134,996. Latta, J. G. Dec. 7, 1918. Conveyer and blast apparatus, injector.-Air is compressed in injector apparatus arranged in series in which the motive fluid is water which has previously been entrained by steam. Steam issuing from a nozzle C, Fig. 1, induces water up a pipe A, and the mixture issuing from a nozzle E induces air through a valve H and passes through a nozzle F into an eccentric whirling chamber J arranged round a water-cooled receiver K. The water passes back to the injector, and the compressed air passes by a pipe to the injectors and receivers of the succeeding stages. In a modification, the air mav be compressed in several steps at each stage. In this case, Fig. 2, the mixture from the nozzle F is acted upon by a mixture of water and steam issuing through a nozzle P, into which it had been forced by a steam nozzle R.
Patent GB-696250-A (GB)
Title: Improvements in and relating to ferromagnetic materials
IPC: C04B35/26
Filed: 1951-06-07
Abstract: <PICT:0696250/III/1> A body of single or mixed ferrite material having an initial permeability of at least 20, a loss factor tans of not more than 0.06 at frequencies up to 10KC as measured on a solid ring of the material, and a pore volume of less than 5 per cent, is obtained by solidification from a melt.  In making manganese ferrite a chamotte crucible 1 is filled with aluminium oxide powder 2 heated to just below its melting point into which is pressed an aluminium oxide crucible 3.  Inside this discs 5 of Fe3O4 alternate with layers 6 of Mn3O4.  The crucible has a thermocouple 4 attached and is covered with an iridium plate 7. Nitrogen is led at 11, 12 through the surrounding glass dome 8 and the contents of the crucible heated slowly by h.f. currents in the coil 10 until just below their melting point.  The nitrogen is gradually replaced by oxygen, the temperature is then raised until the oxides melt, maintained for five minutes, slowly reduced until the oxides resolidify and then rapidly reduced to 1300 DEG C.  The oxygen is replaced by nitrogen and the cooling completed slowly. Sufficient heat is produced by induction because both the Fe3O4 used as a starting material and the ferrite at high temperatures have relatively high conductivity.  As an alternative the crucible may be of high melting point alloy, e.g. platinum with iridium and/or rhodium.  Also the molten material may be cast in a mould.  Specification 696,216, [Group XXXV], is referred to.

Title: Improvements in and relating to transistor amplifiers
IPC: H03F1/30
Filed: 1957-05-02
Abstract: 883,245. Transistor amplifier circuits. MURRAY, J. S. April 29, 1958 [May 2, 1957], No. 14029/57. Class 40(6). A transistor amplifier comprises a common base input stage D.C. coupled to a succeeding common emitter stage, the base-to-collector voltage of the common base stage being stabilized by obtaining the base bias from an emitter resistor of the second common emitter stage, the D.C. resistance included in the biasing loop being smaller than 3000 ohms. The Figure shows a four-stage amplifier comprising a grounded base input stage, an emitter follower second stage, a grounded base third stage and an emitter follower output stage. The collector-to-base voltage of the first stage is maintained at a desired value by connecting the base to a tap on an emitter resistor in the third stage capacitor 20 serving to prevent A.C. feedback. A.C. negative feedback is however provided from the output to the input of the amplifier by means of a network 24. In an alternative circuit (Fig. 2, not shown) two amplifiers similar to the first three stages of Fig. 1 are arranged in push-pull with the base bias of the first stage obtained from a common emitter resistor of the third stage. The second stage of this amplifier uses transistors of opposite conductivity type from the other stages. Specification 809,207 is referred to.

Title: Improvements in or relating to the manufacture of paper from fibres of polyethylene terephthalate
Inventor: SCHOENBERG ENDRE
Filed: 1960-04-21
Abstract: 906,889. Treating paper. ONDERZOEKINGSINSTITUUT RESEARCH N.V. April 21, 1960 [April 23, 1959], No. 14055/60. Class 96. Paper manufactured from polyethylene terephthalate fibres is treated with chloral hydrate for a time sufficient only to cause the fibres to swell and adhere together. The paper, which may comprise other fibres, e.g. cellulosic, organic or inorganic fibres, is immersed or sprayed with a solution at first insufficiently strong to cause swelling but which, after squeezing out the surplus, e.g. using pressure rolls, is sufficiently concentrated by evaporation, e.g. by passing the paper over calender rolls heated to 140‹ to 150‹ C., to become effective. An acetone solution initially containing, by weight, 30 to 35% chloral hydrate, is concentrated, as described, to 70 to 75% strength; alternatively a 47 to 50% aqueous solution may be used. Thereafter the swollen condition of the fibres is removed by passing the paper through compression rolls and any residual acetone and/or chloral hydrate removed by further evaporation. The chloral hydrate solutions may incorporate small amounts of halogenated hydrocarbons to reduce fire risk.
Patent GB-141083-A (GB)
Abstract: 141,083. Western Electric Co., and Polinkowsky, L. Feb. 27, 1918. Automatic and semi-automatic exchange systems.-A connecting-circuit is extended to a desired line over automatic switches under the control of a controlling-equipment associated with the connecting-circuit by means of relays, which serve to establish the through talking connexion only after having been energized and then deenergized. The invention is described as applied to a system in which calls are extended from an A-operator's position through a semi-automatic B-operator's position to a subscriber on an automatic satellite or distant automatic exchange connected to the main exchange over a two-wire trunk. On the receipt of a call, over an orderwire, the B-operator assigns the junction to be used and depresses the assignment key individual to that junction, whereupon one of two relays is energized to connect the junction to an idle one of two register sets common to a single keyboard. Additional relays are provided to ensure that the selection-controlling circuit is not completed until the A-operator has inserted the plug in the jack of the assigned junction. When the selecting operations are complete, the first-mentioned relay de-energizes and completes the through-circuit from the A-operator to the selected line. This system is identical with the system described in Specification 133,343. In addition, the invention is shown applied to a trunk line outgoing from a manual magneto board A, Fig. 5, and extended over a semi-automatic B-operator's position, as in the other system, to an automatic exchange-over trunk 230. When the B-operator depresses the assignment key 601 of the assigned junction 230, relays 602, 605 (or 603, 613) are energized, as in the other system, to connect the junction to an idle register set. When the A-operator inserts her plug in jack 700, a slow-acting relay 609 energizes a relay 611, which locks up over its right-hand winding and a relay 608, which completes the fundamental circuit over the trunk 230. After the selection is complete, relays 602, 605 (or 603, 613) de-energize, relay 605 (or 613) completing the through-connexion from the A-operator to the called line. On the response of the called subscriber, relays 616, 617 are energized, relay 616 closing a circuit for relays 618, 619. Relay 618 closes a holding-circuit for itself and relay 619 dependent on relay 609. Relay 619 prepares a circuit for operating a clearing-out relay 610 on the A-operator's cord, this circuit being completed when the called subscriber replaces his receiver. The withdrawal of the plug de-energizes relays 609, 611. 608 and releases the connexion. Specification 141,081 also is referred to.

Title: Improvements in or relating to the manufacture of tetraalkyllead compounds
IPC: C07F7/24
Filed: 1951-06-15
Abstract: Tetra-alkyl lead is prepared by reacting an alloy of lead with an alkyl halide or sulphate at an elevated temperature, characterized by using a sodium-lead alloy in the form of flakes having at least one surface comprising predominantly the projecting natural faces of identifiable octahedral crystals projecting from a common base.  The alloy is preferably a monosodium lead alloy in the form of flakes of from 0.01 to 0.05 inches mean thickness (although a mean thickness from about 0.008 to about 0.12 inches is satisfactory) and 1/8 to 1/4 inch in maximum dimension.  The reaction may be carried out at a temperature in the range of 70 DEG  to 100 DEG  C., and the reaction period may be between 5 and 30 minutes.  A liquid alkyl halide may be used in excess for the reaction.  The axial dimensions of the identifiable crystals of the sodium-lead alloy used may be from 10 to 50 per cent of the arithmetic mean thickness of the flake.  A suitable method for preparing the alloy is given in Specification 707,074.  Catalysts or accelerators normally used in tetra-alkyl lead formation can be used in the above process, e.g. anhydrides of carboxylic acids, non-quinoidal ketones such as acetone, esters of carboxylic acids, amides, acetals and aliphatic aldehydes. Other lead-sodium alloys apart from monosodium lead alloy which may be used are of the composition Na2Pb, Na9Pb4 and Na4Pb.  Alkyl halides or sulphates which may be used are methyl chloride and bromide, ethyl chloride, bromide and iodide, isopropyl bromide and diethyl sulphate. A number of examples are given.
