IPC: B65D47/06
Filed: 1957-01-30
Abstract: 887,211. Container closures. WADDING- TON, R. S., and DUVAL, B. Jan. 28, 1958 [Jan. 30, 1957], No. 3287/57. Class 125(3). [Also in Group XVIII] A pouring stopper for a container has a tubular plug 7 of rubber or other elastomeric material formed with flanges 8, 9 which define a groove to receive the neck of the container, the flange 8 being of decreasing diameter over its lower portion and having a maximum peripheral size which is just insufficient to prevent the deformation necessary to insert the plug without deformation of the inner surface thereof, such deformation being prevented by a pouring tube 14 so that when inserted the plug cannot be withdrawn. A rubber valve plate 17 is held seated in the lower end of the tube by a spring 18 compressed between a partition 19 and a button 20 linked with plate 17 by a rod 21. The tube has a liquid delivery port 24 and an air inlet port 25 which are covered by plug 7 when the tube 14 is pushed inwardly. If the container is placed on its side, tube 14 is filled with liquid through ports 26 and when the tube is pulled outwardly a fixed quantity of liquid is discharged from port 24, air entering via port 25. In a modification, Fig. 4, a plug 28 with flanges 29, 30 is closed at one end by a thin diaphragm 32 serving as a transit seal and a flexible pourer tube 33 is provided. In a further modification, Fig. 5, the plug has an inclined tube 39 divided by a septum 40 and initially sealed by a wall 45, a metal reinforcing sleeve 51 being provided.

Title: Improvements in or relating to heterodyne systems suitable for use in wireless reception
IPC: H03D7/08
Filed: 1931-02-02
Abstract: 360,289. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Roberts, W. van B. ; 155, Hodge Road, Princeton, New Jersey, U.S.A.) Feb. 2, 1931, No. 3345. Convention date, Jan. 31, 1930. [Class 40 (v).] The detector-oscillator of a supersonic heterodyne receiver is arranged so that feed-back from the local oscillation circuit to the aerial circuit is prohibited, one terminal of each circuit being connected to a point of common radio frequency potential; the arrangement also permits of satisfactory ganging of the two tuning condensers. Coupling between the aerial circuit 1, L, and the local oscillation circuit 2, 3 is effected through a coil N. As the potential at the bottom of N due to current in L is zero, oscillations in O will not produce potential difference between aerial and earth. As the circuits S, 0 are connected to ground, the moving vanes of condensers 1, 3 are at the same potential and unicontrol may be employed. Grid biasing is effected by a resistance R and condenser B in preference to a biasing battery in place of B. Oscillations in 0 may be produced from a separate oscillator instead of the autodyne shown.

Title: Programme-controlled data processing systems
IPC: G06F13/24
Filed: 1972-01-26
Abstract: 1351394 Automatic exchange systems SIEMENS AG 26 Jan 1972 [26 Feb 1971] 3549/72 Heading H4K A program controlled exchange includes a store for both data and programs, a program control unit which undertakes overall control during all programmed operations and a communication control unit instructed by the program control via instruction register locations in the store and arranged (i) to scan incoming lines and in accordance with bits of its instructions in the associated instruction register locations to (a) enter detected polarity changes in a first storage zone in locations permanently associated with individual lines, (b) to transmit detected polarity changes on outgoing lines specified in those instructions or (c) to cause an auxiliary storage location to be associated with the instruction location, and (ii) to commence at regular intervals to hunt through locations of a second storage zone for commands relating to read out of polarity changes to outgoing lines. In the embodiment the bits are effectively call state bits and a bit set under special circumstances, e.g. when a conference or broadcast connection is required, the setting of this last mentioned bit causing the auxiliary storage location to complement the instruction register location for the purposes of the associated call. During call processing the program control unit normally gains access to the first storage zone, which functions as a buffer store, at regular intervals which are such that the buffer does not normally overfill. If however the buffer becomes full due to multiple recording due to contact chatter etc. flag bits are set to interrupt the normal cycle of the program control unit. If the outgoing lines employ several different transmission rates the second storage zone may be divided into sections some of which are scanned during every hunt performed by the communication control unit and some of which are scanned during only alternate or selected hunts. The sections are end marked and jump instructions etc. may be followed.

Filed: 1973-01-25
Abstract: 1396244 Fuel elements SIEMENS AG 25 Jan 1973 [26 Jan 1972] 3949/73 Heading G6C A vented fuel rod comprises a thin-walled metal casing 1 housing the fuel and closed at its upper end by a plug 4 formed with a central bore 4a, and a metal cam 7 containing a pressed-in gas-absorbing filter material 6, e.g. active carbon, welded to the plug 4 and extending down within the casing 1. The lower end of the can 7 is closed by a plug 8b formed with a central bore 8a. The plugs 4, 8b are also formed with dished recesses in which are received porous bodies 9, made for example of sintered Al 2 O 3 . The function of the lower body 9 is to supply fission products, without a large pressure drop and in finely distributed form, to the filter material 6. The filter material 6 retains the fission products for a certain period, after which they leave via the upper body 9 and the bore 4a. The retention time is influenced by the upper body 9 which is of similar porous material to the lower body 9. In a modification (Fig. 3, not shown), the plug 8b is dispensed with and in its place the lower body 9 is inserted as an end plug into the can 7 to which it is brazed or hard-soldered. In a further embodiment (Fig. 1, not shown), the can 7 forms an upward extension of the casing 1, being welded to a plug with central bore itself welded to the upper end of the casing.
Patent GB-766512-A (GB)
Title: Preparation of organic nitriles
IPC: C07C233/00
Filed: 1955-02-10
Abstract: The invention comprises the nitriles of tetracycline, oxytetracycline and chlorotetracycline, and their preparation from the antibiotics (i.e. CONH2-->CN) by treatment with an acid halide and a normally liquid organic base.  The acid halide may be an aryl sulphonyl, aryl carboxylic or carbonyl halide and the antibiotic may be used in the form of salt.  The organic base may be used in excess (e.g. 2 mol. per mol. of antibiotic) to serve as reaction medium, addition of the halide being made at such a rate that the temperature does not exceed 60-70 DEG  C.  A different inert solvent may however be employed. Suitable acid halides are benzenesulphonyl chloride, naphthalenesulphonyl chloride, benzoyl chloride, dinitrobenzoyl chloride and phosgene. Esterification of hydroxyl groups often occurs simultaneously, these being subsequently hydrolysed back to free hydroxyl groups. Alternatively the products may be subsequently esterified and/or the nitrile groups reduced to amino and acylated. Examples show the production of O - benzenesulphonyl - oxytetracycline nitrile and its triacetate, chlorotetracycline nitrile and oxytetracycline nitrile.

Title: Improvements in knitting machinery
IPC: D04B9/26
Filed: 1939-02-07
Abstract: 524,774. Knitting machines. SCOTT & WILLIAMS, Inc. Feb. 7, 1939, No. 4008. Convention date, July 21, 1938. [Class 74 (ii)] The yarn fingers 6 of a circular machine are urged by springs 12 into yarn-feeding position and are held out of feeding position by detents 32, one for each yarn finger. The detents 32 hold in position levers 20, each having an end 24 engaging a notch in the usual push bar 14, and are tripped to release the levers 20 by members 40, each of which is arranged to move in any of three paths. The members 40 are mounted upon an oscillating bracket 46 which is actuated once per revolution of the needle cylinder by a cam 72. To determine the path of the members 40, a finger 108 is moved under control of stops upon a pattern chain into alignment with either of the members 40 or to a position removed from them. When the finger 108 is brought into alignment with a member 40, the member is rocked about its pivot 44 so as eventually to come beneath an arm 35 of its detent 32, see Fig. 3, and upon movement of the bracket 46, the member 40 depresses the detent to release the spring-controller lever 20 so 'that its yarn finger drops into action due to its spring 12. A pivoted yoke 48 carries a pin 50 which is engaged by a notch 52 in each of the members 40, so that when a member 40 is moved by the finger 108, the remaining members 40 are depressed to the position of the member 40<SP>1</SP> in Fig. 3. This permits the positive movement of the push rod 14 of a yarn finger going out of feeding position in correct time relation to the ingoing movement of the selected finger. since the partly depressed members 40 are moved with the bracket 46 so that the member 40 corresponding to the yarn finger moving to inoperative position engages a notch 38 in the lever 20 and moves it and the push rod. When the finger 108 is not in alignment with either of the members 40, the members 40 move in a path above the end 35 of the detent 32. To permit the yarn fingers to be moved into inoperative position independently of the pattern chain, e.g., during heel knitting, a lever 90 operated by a high cam 98 on the main pattern drum 16 engages tail pieces 39 of the detents 32 to move them to release the levers 20. Yarn cutting and trapping means operated by a separate pattern chain are provided and are operated upon yarn change. A lateral pin is provided upon this chain to prevent operation of the cutter and trapper when certain yarn changes take place. Specification 259,529, [Class 74 (ii)], is referred to.

Abstract: 1,001,907. Magnetic record/playback systems. S. OKAMURA. Oct. 24, 1962 [Oct. 24, 1961], No. 40298/62. Heading G5R. [Also in Division H4] A magnetic tape recorder, particularly intended for television signal standards conversion, uses oblique video tracks on a preferably endless tape loop, but with successive lines arrayed raster-fashion along lines 15-18 normal to the direction of the tracks, Fig. 2. To decrease the line-standard, the playback angle #<SP>1</SP> is made greater than the recording angle # by changing the wrap angle of the helix, the tracks being such that a head tracking portions of adjacent tracks produces an output equal to the mean content of the tracks. The linestandard may similarly be increased (playback angle #<SP>11</SP>). To change the frame-standard, the headspindles 5, 9, Fig. 1, are driven at differing rates whereupon the frame-blanking portions extend obliquely across the tape at an obtuse angle to the signal tracks (Fig. 4, not shown) instead of extending along the tape edges at 19, 20, Fig. 1. The Specification includes a mathematical analysis of the standards-conversion and states that the system can also be applied to cylindrical and disc-form records, but without detailing the scanning arrangements.
