Abstract: 972,167. Ventilators. G. W. MINDS. July 13, 1962 [July 13, 1961], No. 27074/62. Heading F4V. In a louvre structure comprising inclined panels, having their longitudinal axes horizontal, extending between two vertical jambs, each panel end is received by a pair of vertically staggered, inward facing notches, one at the front and one at the rear of the adjacent jamb, the distance between the two notches being slightly less than the width of the panels so that the latter are bowed about their longitudinal axes when forced into the slots. As shown, Fig. 2, each jamb 10 has a web 17 extending between walls 15 and 16, flanges 18 and 19 facilitating securing of the jamb to a suitable frame structure, and flanges 20 and 21, with guide flanges 22 and 23, being used toretain the louvre panels. A series of notches 24 in flange 20, Fig. 4, and 25 in flange 21 have horizontal faces 27 and 28 respectively, and inclined faces 26 and 29 respectively. Each panel 14 has on its longitudinal edges, vertical lip portions 30 and 32 carrying horizontal seating flanges 31 and 33 respectively; the edges so formed on the panels corresponding in shape to the notches 24 and 25. The jambs are joined to a sill member channel section at their bases, and by a similar channel member at their upper ends. The jambs and panels are of aluminium or similar elastically deformable material.

Title: Improvements in or relating to telephone repeater circuits
IPC: H04B3/10
Filed: 1924-11-13
Abstract: 245,554. Western Electric Co., Ltd., (Western Electric Co., Inc.). Nov. 13, 1924. Manual exchange systems; two-way repeating systems.-Four-wire transmission circuits each with a pair of echo suppressor units are coupled in tandem by cord-circuits so that all the echo suppressors except one pair are disabled. The cord-circuits have four plugs for connecting the line and network jacks, the usual balancing networks at the junction being unnecessary. In one arrangement (Fig. 2), relays X, Y associated with the coupled transmission circuits are energized over sleeve circuits and disable the shunting echo suppressors A-B, C-B. In another arrangement, Fig. 3, both the echo suppressors of each transmission are controlled by a pair of relays one of which is polarized. If the cord Y is connected first to the circuit X, control relays F1, G1 both energize without effect on relay H1, but relay B1 also operates, so that when connection is made to the circuit Z, relay F2 energizes and relay G2 being polarized does not, whereby relay H2 operates and disables the echo suppressors Y-Z, Z-Y. This arrangement is particularly useful since an ordinary two-wire line may be included in the connection.

Title: Improvements in or relating to frequency synthesisers
Inventor: THROWER KEITH REX
IPC: H03B21/02
Filed: 1965-06-26
Abstract: 1,107,630. Frequency changing systems. RACAL COMMUNICATIONS Ltd. 5 Sept. 1966 [26 June, 1965], No. 27181/65, Heading H3F. A frequency synthesizer comprizing a final oscillator covering one decade of a desired output frequency range, is characterised in that other decades are provided by changing the output of the oscillator to a higher intermediate frequency and changing the I.F. back to the required decade. In the example shown the final oscillator covers the range 21À6-31À6 Mc/s. An intermediate mixer converts this to a range 126À6-136À6 Mc/s., and this is converted back into one of the two ranges 1À6-11À6 or 11À6-21À6 according to which of the two oscillators shown is connected to the output mixer. In an alternative arrangement the intermediate frequency is different according to the required output range. The three reference oscillations at 105, 115 and 125 Mc/s. may be derived from a single source or by using three stable oscillators. The final oscillator may be controlled in frequency as in Specification 1,064,952.

Title: Modification of starch
Inventor: HJERMSTAD ERLING TORMOD
IPC: C08B31/06
Filed: 1962-07-16
Abstract: Native, white, ungelatinized granular starch is mixed with 0.01-0.15 mol per mol of starch of a water-soluble inorganic phosphate capable of esterifying starch, and 1-10 mol per mol of the phosphate of a water-soluble organic amide containing a -CONH2 group, in presence of sufficient water at pH 5.0-7.5 to dissolve phosphate and amide, and the mixture is heated as a continuous solid phase at 220 DEG F.-280 DEG F. until the starch contains in molecular combination at least 0.1% by weight of phosphorus and at least 0.2% by weight of nitrogen. Heating is terminated before appreciable discoloration of the starch occurs.  The continuous solid phase is obtained by dewatering, e.g. by filtration, the slurry of starch in aqueous phosphate-amide solution, and drying the cake.  The solid is preferably powdered before heating, which may be carried out in vacuo.  Suitable phosphates are sodium, potassium and ammonium salts of orthophosphoric, metaphosphoric, pyrophosphoric and polyphosphoric acids, and alkyl-substituted phosphoric acids.  Specified amides are formamide, butyramides, caproamides, acrylamide, carbamide (urea), malonamide, phthalamide, 1,3-dimethylurea, allylurea and acetylurea.

Title: Radio receiving systems
IPC: H03G3/26
Filed: 1933-10-04
Abstract: 415,598. Valve circuits for wireless reception. RADIO FREQUENCY LABORATORIES, Inc., 708, Main Street, Boonton, New Jersey, U.S.A.-(Assignees of Farnham, P.O.; Boonton, New Jersey, U.S.A.) Oct. 4, 1933, No. 27299. Convention date, Nov. 4, 1932. [Class 40 (v).] The bias voltage applied to a rectifier, which forms part of an automatic volume control system, renders said rectifiers inoperative for input voltages of below a certain value and is automatically reduced by means responsive to the rectified output, when input voltages above said value are rectified. As shown, the valve 5 comprises a triode portion K, G, P and two diode anodes A1, A2. Signals from a high frequency amplifier 1 are applied from the secondary of a transformer 3, 4 to the diode A2, K which has a load resistance 6 from which, through filter 9, 10 are applied the D.C. and low frequency potentials developed therein, to the grid G. The triode acts as a low frequency amplifier with an output transformer 11 and as a D.C. amplifier with an output resistance 16 which is included, together with part of a potential divider 14, 15 across the H.T. source, in the diode circuit. The resultant D.C. potential due to the resistances 16, 14 is applied through a filter 18, 7 to the anode A2 and delays rectification until a predetermined signal strength reaches the diode. Thereafter, any increase in signal strength results in a diminution of the current in resistance 16 and a reduction of the negative bias on the anode A2. Noise suppression is due to the inability of the signal detector diode A2 to rectify signals of below the predetermined strength, and also to the large negative bias on the grid G in the absence of signals. The diode A1, K is fed with signals from the primary 3 through condenser 19, and its load resistance 20 produces A.V.C. potentials which control the gain of the amplifier 1 through the filter 21, 22 and lead 23. The delay potential on the anode A1 due to the cathode resistance 16 is also automatically reduced when signals become strong enough to overcome the delay voltage on the detector anode A2. In a modification, the input to both diodes is derived from the secondary 4 and by means of a switch the low frequency output may be taken from the resistance 16 or between the grid G and earth.

Abstract: 463,663. Refining sodium and other metals. DU FONT DE NEMOURS & CO., E. I. Oct. 4, 1935, No. 27493. Convention date, Oct. 4, 1934. [Class 82 (i)] [Also in Group XXXVI] In the production of sodium by electrolysis of a fused mixture of sodium chloride and calcium chloride, the liquid sodium, containing calcium as impurity is collected in an inverted trough 7 surmounting the cathode 4 and passes upwards through a vertical conduit 8 the external part 9 of which is provided with heat radiating fins 14 whereby the metal mixture is cooled to a temperature between 100 and 200 C. ; by this means the calcium is precipitated out, and substantially pure sodium overflows into the receiving vessel 12. The conduit 8 should be so dimensioned that the upward flow is sufficiently slow to permit settling of the precipitated calcium, this returning to the cell and producing more sodium by reaction with sodium chloride. An agitator may be provided within the conduit 9 to remove precipitated metal from the sides in order to prevent plugging ; this should be operated slowly or intermittently in order not to prevent settling. Cool air may be blown over the heatradiating surface or this may be replaced by a cooling jacket ; cooling may also be applied within the cell. The invention is applicable generally to the separation of unwanted metal from a mixture resulting from the electrolysis of a mixture of fused salts.
