Title: Improvements in or relating to transmission systems for transmitting pulses
IPC: H03M13/17
Filed: 1965-03-02
Abstract: 1,041,496. Data transmission. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 2, 1965 [March 5, 1964], No. 8848/65. Heading H4P. In a data transmission system which is subject to error bursts of a duration not exceeding the interval between them, the transmitter feeds the transmission channel both direct by way of a first channel and also via a delay which has a duration equal to the longest error burst to be corrected and included in a second channel. At the receiver the signals in the second channel, which were subject to delay, are passed to a comparator, and the signals in the second channel are passed via a delay equal to that of the transmitter, to the same comparator. The comparator controls a switch to which are passed the signals fed to the comparator. When an error is detected in the second channel by inequality of the signals the switch is reversed after delay equal to the delays mentioned above, whereby data from the second channel, instead of the first, is fed to the output unit. After a further like dolay, the switch reverts to its original position. To correct errors occurring in either channel the system is modified by the addition of a binary adder which combines the signals of the first channel with the second at both the transmitter and the receiver. A recoding unit may be placed in the input to each binary adder.

IPC: A23L7/10
Filed: 1941-07-15
Abstract: 558,141. Cereal preparations. STEVENS, A. H. (National Biscuit Co.). July 15, 1941, No. 8949. [Class 58] [Also in Groups V, VI and XIII] A crisp cooked bran food in the form of small pellets is made by coating finely-divided bran with an edible binding material, such as sugar, fruit juice or syrup, malt extract, honey, gelatine, starch or agar agar, or a mixture of these, cooking under steam pressure until it becomes adherent, extruding in a plurality of strings and directing a blast of air through the strings while they are being extruded and divided into pellets. Bran may be fed from a mill 5 by conveyers 7, 9, 11 to one or more pressure cookers 12, binding solution being fed from a tank 13 to the hopper 10 of the screw conveyer 11, and the cooked bran passed directly or by a conveyer 38 to a screw feed, or grooved roller, extruding machine 17 opening into a tumbler 19 to which air is supplied by a pipe 18. The pellets formed in the tumbler may fall directly or by way of a conveyor or shoot 21 into a vat 20, Fig.1A, through which air is passed from a blower 22 supplying the pipe 18. When the pellets are surface dried they are transferred to a second vat and further dried by air supplied by a blower over heating coils and finally toasted in a rotating cylindrical oven. The toasted pellets may be cooled in vats, similar to the vats 20, or on a belt before packaging. Alternatively, the pellets may fall from the tumbler 17 on to a vibrating screen 39, through which cool air is directed from a distributor 40, and be carried thence by a conveyer 42 to a cooling and drying tower 43, Fig. 4A, having an upper section supplied with cool air through an inlet 47 and lower sections supplied with hot air through inlets 55 and a spreader 45 from which the pellets fall successively on to perforated screens or baffles 46 adjacent louered air outlets 44 on opposite sides. From the tower, the pellets may be carried by conveyers 58, 59 to a vibrating screen 60 and drip into tempering bins 61 or directly into the toasting oven.

Title: Formation on girders of layers of settable material
IPC: E04F13/06
Filed: 1971-12-31
Abstract: 1378752 Cladding girders SIKA CONTRACTS Ltd 31 Dec 1971 [8 April 1971 4 Aug 1971] 9070/71 and 36561/71 Heading E1K A girder is coated with a settable material, e.g. with mortar, to a predetermined depth by arranging guide member adjacent to but spaced from the girder, applying the settable material so as to cover the guide members and to extend beyond the eventual outer surface of the settable material and striking off excess material by drawing an edge of a tool along an adjacent pair of guide members, whereby the tool determines the form of the outer surface of the settable material. As shown in Fig. 3 of Provisional Specification 9070/71, four wires 12 are stretched adjacent the edges of an I-beam 10 which is then coated with mortar 14 until the wires are just buried. Optionally the wires are tied together to preserve the desired spacing. Excess mortar is struck off by moving a tool straight edge along the wires to produce the structure shown, from which the wires may be removed before the mortar sets. In another embodiment in which the guide members remain buried in the product, Fig. 2 of Provisional Specification 36561/71, brackets 110 are secured at intervals along the edges of a girder 112, each bracket including a fin 122 and a guide member in the form of a folded strip 114, preferably of metal plastering corner bead, is attached to the fins along each girder edge. Brackets of different sizes may be used on the same girder to provide for mortar layers varying in thickness. In a further modification, Fig. 3 of Provisional Specification 36561/71 not shown, the fins 122 are shorter and are connected by non- ferrous guide member strips which are similar or identical to the coating material and may incorporate reinforcing elements such as glass fibre or steel wire or mesh.

Title: Improvements relating to telephone exchanges and electrical interconnecting means therefor
IPC: H04Q3/58
Filed: 1940-05-25
Abstract: 541,415. Automatic exchange systems. STUART, A. J., and LOW, F. A. May 25, 1940, Nos. 9229/40 and 156/41. [Class 40 (iv)] In a system in which subscribers are connected to unattended switching stations provided with three-wire outgoing junctions to an exchange which may have no subscribers connected to it directly, some or all of these junctions are shared between two or more switching stations. Preferably a station has at least one first choice junction individual to it, later choices being shared with an increasing number of other stations. The commoning is effected in the stations or in separate junction boxes. Calls incoming to a switching station are completed over separate 2- or 3-wire junctions terminating in final selectors. The exchanges may be satellites of a non-director main exchange or may be director exchanges. In systems in which a calling subscriber is connected to an outgoing junction by a line-switch controlled by busy markings it is preferred, since these busy markings may be applied over a circuit of considerable resistance from another station, to use the switch shown in which a separate test relay N is initially energized over normal terminals and is subsequently held over the c-wires of busy lines. In systems depending on a batterymarking for idle lines, the cut-off relay has a low-resistance test winding and a high-resistance holding winding. Where finder/preliminary selector links are used a link is marked busv after use until the preliminary selector reaches normal to ensure that the junctions are tested in the right order.

Title: Improvements in means for producing intermittent electric currents
IPC: H01C7/04
Filed: 1935-03-25
Abstract: 450,710. Electromagnetic and thermal switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Patent Treuhand-Ges. fur Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin) March 25, 1935, Nos. 9230 and 9565. [Class 38 (v)] [See also Group XI] An arrangement for controlling electric currents comprising a switch in parallel with a resistor having a large negative temperaturecoefficient is controlled by current through the resistor so that the switch closes when the current reaches a predetermined value or when a predetermined amount of heat has been generated by it in the resistor, the switch and resistor being contained in a common closed envelope preferably evacuated or filled with neutral gas. As shown in Fig. 1 (9565/35), the high negative temperature-coefficient resistance 1 is normally in series with the operating coil 2 of an electromagnetic switch, both switch and resistor being mounted within the glass bulb 3 with screw cap 4. As the resistance 1 is heated by the current flowing through it and the coil 2, its resistance falls rapidly, the current correspondingly increasing until the armature is attracted and closes contacts short-circuiting the resistance. The armature is then maintained in its closed position. In a similar arrangement shown in Fig. 2 (9565/35), the resistance 1 is in series with a heating coil 51 surrounding a bimetallic strip which controls contacts 5 for short-circuiting the resistance. This action takes place when the current in the heating resistance rises to a sufficiently high value as the result of a corresponding decrease in the value of the resistance 1 so causing bending of the strip. The connections in this construction pass through a valve base 6. In a variant of this arrangement the resistance of high negative temperature-coefficient may act also as a heater, as shown in Fig. 1 (9230/35). In this case, the arrangement acts as a continuously-operating thermal interrupter for an incandescent lamp 3. The resistance 4 is of such a value that normally tho filament does not glow appreciably, but when the strip 5 is bont sufficiently by the heat transmitted to it by the rod 4 of uranium dioxide the contacts short-circuit the resistance and the lamp glows brightly. On cooling down, however, the strip opens the contacts, after which the cycle of operations is repeated. The switch and resistance may be mounted in the same onclosure as the lamp filament from which it is protected by a mica shield 9, Fig. 2 (9230/35). The switch in all of the constructions, togethor with the high negative temperature-coefficient resistance with which it is associated, is mounted within a sealed envelope 3 or 6, which may be evacuated or filled with a neutral gas. Other types of thermal switches than the bimetallic may be employed in conjunction with resistances of high negative temperature-coefficient, as for example the contact gas thermometer type 7 shown in Fig. 2 (9230/35), surrounded by resistor 8. A further similar type is employed in Fig. 3 (9565/35) (not shown).

Abstract: 433,606. Suction cleaners. HOOVER, Ltd., Perivale, Greenford, Middlesex.-(Assignees of Smellie, D. G. ; 357, 23rd Street, Canton, Ohio, U.S.A.) March 26, 1935, No. 9450. Convention date, May 24, 1934. [Class 8 (i)] In a suction cleaner comprising a container usually mounted on skids containing a suction fan, a driving-motor, a filtering-device and a flexible hose carrying a cleaning-nozzle, the fan is connected to the filter on its suction side and has an adjustable valve adapted to connect the hose either to the pressure side of the fan or to the intake side of the filter. The cleaner shown embodies a central body 1, motor casing 2, and a removable cylindrical, dust-bag container 4 secured by latches and staples. The unit is supported on skids 7. An interior curved wall 10 is spaced from the body wall to form pockets 11 which extend the length of the body and are open to the atmosphere through openings 12 which face the motor end of the cleaner. A chamber 9 houses a fan 15. The end of the body 1 carries circular flanges 17, 18 for supporting the container 4 and a dust-bag 25 which is spaced from the wall thereof. A central partition has a central opening 13 leading to the fan, and connected by a passage 14 to the container. The flange 18 surrounds an opening leading to a passage 20. The tops of the chambers 11 are open ; the upper ends of the passage 20 and chambers 11 form ports 21, 22 which are controlled by a hoodlike valve 28 connected to the suction-hose 30 and which is rotatably mounted on the casing by a bolt 33 and is secured so that the inlet 29 engages either the port 21 or 22 by a winged nut. Normally the motor draws air through the inlet 21, passage 20, dust bag 25, passage 14 and exhausts through outlet 22. The cleaner can be converted to a blower by reversing the valve 28 so that chamber 32 seats over the exhaust opening 22. The air then passes through openings 12, chambers 11 into the main part of the valve through openings 21, passage 20, bag 25, container 4, and passage 14 through the fan to the discharge 29. The noise is reduced by providing the valve and chambers 11 with sound-deadening lining, and the chambers 11 with lined projections 36 which cause the air to follow a tortuous path.
