Abstract: 1304421 Transacting sales of fungibles INSTITUTIONAL NETWORKS CORP 24 Feb 1970 [24 Feb 1969] 8827/70 Heading G4A A computer is arranged to transact sales of fungible properties, e.g. stocks and shares, and comprises a central processor, and a number of peripheral subscriber stations each comprising a typewriter input and a printer output. The computer receives incoming buy and sell offers from the subscriber stations and arranges these in buy and sell offer lists ordered by price, offers bearing the same price being ordered according to their time of arrival. The system automatically compares each incoming buy offer with the ordered sell offers and vice versa. Each match causes a transaction to be completed and the parties concerned, identified by a bit field associated with each offer, are informed. The procedure repeats until either the incoming offer is fulfilled or the list exhausted, any remaining part of the incoming offer being placed in the appropriate list. Each offer may be broadcast to all the subscribers via a separate channel. Each subscriber may call for a print out of the lists and may respond either to this print out or to a "broadcast". If the reply "matches" an offer a transaction is completed otherwise the offering subscriber is informed of the reply which he may accept, causing a transaction to be effected, or make a further offer. The subscribers are preventing from accessing the subscriber offer identifications and each offer is also referred to by a reference number. Data keyed in at a subscriber station may be displayed for checking and rekeyed if erroneous. Printouts may include the date and time of the corresponding action. The Specification contains a detailed description of flow drawings which describe the procedures followed by the computer.

Title: Filtering device for wireless receivers fed by the mains supply
IPC: H03J3/00
Filed: 1925-04-02
Abstract: 232,210. Compagnie pour la Fabrication des Compteurs et MatÚriel d'Usines Ó Gaz. April 8, 1924, [Convention date]. Thermionic amplifiers; filter circuits.-Relates to thermionic receivers of the kind in which noises due to utilizing supply current from the mains are reduced or eliminated by placing the telephones T in series with a condenser C2, and connecting this circuit either across an inductance L in the plate circuit of the last valve or across the secondary coil of a transformer the primary coil of which is in the plate circuit. The closed circuit thus formed is tuned to the mean voice frequency, thus offering in the plate circuit high impedance to voice frequencies, and low impedance to the interfering hum. The invention consists in connecting a second condenser C across the plate inductance L, or across the primary or secondary coil of the transformer, or across parts of these coils. An auto-transformer mav be used instead of the two-coil transformer. The condenser C2 may be omitted. The addition of the condenser C1 enables a smaller coil L to be used, and more effectively suppresses the interfering hum.

Title: Improvements in or relating to circuits for counting electrical impulses
IPC: H03K23/82
Filed: 1943-06-11
Abstract: 566,156. Counting impulses. STANDARD TELEPHONES & CABLES, Ltd., BRAY, F. H., and BROWN, L. R. June 11, 1943, No. 9421. [Class 40 (iv)] [Also in Group XL] A chain of cold-cathode discharge tubes break down in succession in response to impulses and each tube when ionised extinguishes the preceding tube. The chain is arranged in closed form so that it may be used to generate make-and-break impulses at the rate of 10 per second, say, from 50 cycle alternating current. Positive battery is applied to the anodes of all the tubes over a resistance R19, and the anode circuits of two of the tubes include the windings of a polarized relay P. Alternating current is fed over a transformer TA to an additional tube T6 which breaks down on each positive half-cycle and applies a voltage surge to condensers C1-5. To start the operation, a key is actuated to connect an ionising potential to the control electrode of T1, whereupon the anode current, which energizes P, charges condenser C6 and builds up a bias on the control electrode of T2. On the return of the key, A.C. is applied and the voltage surge resulting from the first positive half-cycle ionises T2 and its anode current builds up a bias on the control electrode of T3, the preceding tube T1 being shunted out since C6 is fully charged. The tubes therefore break down in succession at each positive half-cycle. As shown, relay P changes over when T3 breaks down to provide impulses with 40 per cent make, 60 per cent break. Other ratios are obtainable by operation of keys K1-3. The chain may be used for counting impulses by connecting a relay in the anode circuit of each tube. When employed for generating impulses, the arrangement may be common to a number of register-controllers. Specifications 436,420 and 555,392 are referred to.

Abstract: 911,123. Removing packing-rings from stoppers. BEECHAM FOODS Ltd. March 8, 1960 [March 19, 1959], No. 7588/59. Class 125(3). A machine for removing sealing rings from stoppers comprises a conveyer table 2 in which are locating holes 1 for positioning the stoppers with their heads downwards, a pair of stripper blades 6 loaded inwards by a spring 7 and engaging the stopper shank between the ring and head of the stopper, and a plunger 8 which pushes each stopper downwards as it lies between the blades 6 thereby removing the ring. A lower table 2a prevents the stoppers from falling through the holes 1 to which the stoppers may be fed either manually or automatically. The table 2 is rotated anti-clockwise by an electric motor through mechanism which includes a Geneva gear. Cam-operated blades 3, supported on a bridge 4, exert an upward force to loosen the rings, the stoppers being held down by a fixed top plate 5. During this operation the table 2 remains stationary due to the action of the Geneva gear. As the plunger 8 descends, the table 2 being again stationary, a shutter (not shown) under the stopper is moved sideways uncovering an opening in the table 2a through which the stopper is ejected. After being stripped by the blades 6, the rings are ejected down a shoot 10 by an air jet nozzle 9. A gauge 11 ejects wrongly placed stoppers.

Abstract: 1537528 Television NORTH AMERICAN @ AIDS CORP 11 March 1976 [14 March Heading H4F out detector employed in a video disc player, uses variable delay line 4, Fig. 1, the delay of which is controlled by unit 7. The FM signal read from disc is demodulated, 9, and simultaneously applied to a drop-out detector 8 which produces a pulse C, Fig. 2, in response to the occurrence of a drop-out. Pulse C enables the demodulated signal appropriately filtered, B, to pass through a gate 11, Fig. 1, on to a transforming unit 12 which develops a pulse D, Fig. 2, of amplitude dependent upon the drop-out magnitude (t c -t 1 ) curve A. Pulse D is employed as the variable delay control signal applied at terminal 6, Fig. 1. In another embodiment, Fig. 3 (not shown), the recovered signal is applied to a second FM demodulator subsequent to a 1H delay, the demodulated signals are subtracted so that the difference is indicative of drop-outs. The drop-out detector monitors the undelayed signal for drop-outs and gates the difference upon the occurrence thereof. An arrangement for avoiding multiple compensation for a single drop-out in this latter embodiment is described with respect to Fig. 4 (not shown). An embodiment of a dropout detector suitable for use is described with respect to Fig. 5 (not shown). Another form of drop-out detector is described with respect to Fig. 6 (not shown), wherein rising and falling edges of the FM signal are used to derive separate zero crossing pulse signals which are filtered, demodulated and subtracted, the difference being applied to the transforming unit. An embodiment of the transforming unit is described with respect to Fig. 7 (not shown), in which the magnitude and polarity of signal disturbance B, Fig. 2, is ascertained in order to generate the requisite control signal. In a further embodiment, Fig. 8 (not shown), a second variable delay line is employed to correct residual error under the control of a signal derived by comparison of the input and output of the first variable delay.
