Title: Method of and apparatus for feeding vitrifiable materials into glass furnaces
Inventor: BRICHARD EDGARD
IPC: C03B3/00
Filed: 1948-08-31
Abstract: 666,641. Charging glass furnaces. UNION DES VERRERIES MECANIQUES BELGES, SOC. ANON. Aug. 31, 1948, No. 22935/48. Addition to 627,642. Class 51 (ii). In apparatus for charging glass furnaces, as described in the parent Specification, in which a layer of batch material is propelled into the furnace on the surface of the molten glass by a continuously moving member, thereby setting up a surface current in the molten glass, batch material is deposited on the molten glass at the sides and/or in front of the member, at points where movement of the glass is induced by the propulsion of the layer, instead of or as well as behind the member. As shown, batch material is fed from a hopper 6 and propelled into the furnace by a bladed roller 8, as described in the parent Specification, and further batch material is fed from hoppers 7, 9 and 13, which may be fitted with vibrators 14, whereby the material is propelled into the furnace in the form of superposed layers 4, 5 and 10. The outlets from the hoppers are indicated by rectangles AB, EF, GH, IJ, KL, MN, OP and QR in Fig. 4. The layers may have different compositions, e.g. cullet may be charged through the hoppers 9 and the remainder of the batch through the other hoppers.

Title: Improvements in or relating to folding hoods
IPC: B60J7/12
Filed: 1920-08-03
Abstract: 170,430. Dicker, S. G. S., (Asfag Akt.- Ges.) Aug. 3, 1920. Hoods.-A folding hood frame comprises front and rear main stays connected in parallelism on each side, the front main stay supporting the hood midway of its length, auxiliary forwardly and backwardly extending stays, a tie-stay between the rear main stay or the connection between the main stays and the rearwardly extending stays, and an auxiliary connection between the main stay connection and the rearwardly extending stay. The main stays a, b are united at their upper ends by a bent bar e extended forwardly to carry the front stay f which is supported by a stay g. A jointed rearwardly-extending stay h is hinged to the stay b, supports a rear stay k and an intermediate stay m, and is connected to the upper end of the main stay b by a stay l. An auxiliary tie-stay p is attached to the bar e and has a slot r receiving a pin s on the stay h. The stay a has a crank t to which is attached a spring o, and is also connected to a lever preferably near the driver's seat. The end of the slot r contacts with the pin s during the raising of the hood to actuate the rear stays. Cords passing over pulleys from a control device may be attached to the hood to assist in folding.

Title: Improvements in and relating to electric ship propulsion
IPC: B63H23/24
Filed: 1934-08-10
Abstract: 437,398. Systems for transmitting mechanical power; control of D.C. motors. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 10, 1934, No. 23170. Convention date, Aug. 10, 1933. [Class 38 (iv)] [See also Group XXXVII] A Ward-Leonard generator 3 feeding a D.C. propeller motor 1 of a ship propulsion system is connected in series with an auxiliary D.C. constant voltage system 7 when the reversible field controller 6 of the main generator 3 is in position for maximum voltage. In this controller position the segment 39 closes its contacts and, providing the current through the constant voltage D.C. generators 20, 21 is too small to operate the relay 22, connects a bus-bar 7 to a resistance 43, the connection being indicated by a signal lamp 38. The contact arm 9 of the resistance 43 is then moved against the spring 10 inserting this resistance in the circuit of the field 4 of the generator 3. In its final position the arm 9, which may be moved manually or by a motor energized only in the full speed position of the controller 6, connects the contacts 35 causing energization of the coils 12, 33. The coil 12 then actuates the changeover switch 11, placing the generator 3 in series with the constant voltage system 7, making a holding circuit for itself through contacts 15 and placing the voltage coil 37 of the load-limiter 5 across the system 7. The coil 33 actuates the switch 31 either simultaneously with the actuation of switch 11 or with a predetermined time lag to cut the resistance 30 out of the circuit of the motor field 2. The arm 9 is then allowed to return slowly to its original position, the resistance 43 being then cut out of the circuit of the field 4 and maximum speed of the motor 1 being secured. The system 7 is thrown out of circuit with the generator if one of the outer conductors becomes earthed by an earth connected relay arrangement 25 which opens contacts 24, 28 and breaks the circuit of coils 12 and 33 and may operate a signal. The resistance 43 of the regulator 8 may be inserted and cut out in steps by means of contactors.

Title: Belt and method and apparatus for making the same
IPC: C14B9/00
Filed: 1935-08-17
Abstract: A rubber belt is reinforced by cords which have been rendered substantially stretchless by treatment under tension with latex or rubber cement and drying whilst maintaining the tension, the cords being laid side by side without interweaving.  The tension is preferably between 25 and 90 per cent of the breaking stress. The belt may be surrounded by an envelope of rubberized fabric. The cord is drawn from a reel round rollers in a bath which contains rubber latex.  The cord then passes a blower to remove excess liquid, and is wound round a pulley braked by a lever to keep the cord in tension. The cord is then festooned over pulleys and passes to the drying chamber from which it is guided to the winding drum.

Filed: 1927-09-08
Abstract: 301,954. Northrup, E. F. Sept. 8, 1927. Induction furnaces.-In a furnace wherein the coil 1 is not penetrated by transformer iron, a magnetic return path 4<d> surrounded by a magnetizing winding 11 is provided external to the coil. The freedom from stray fields thus produced enables metal shells to be used for strengthening the furnace. A number of similar paths may be arranged so as to surround the whole coil, each path having its own winding or one winding being arranged around the whole structure. The magnetizing windings may be in series with the inductance coil. Fig. 14 shows a melting furnace with external iron paths 16 surrounded by windings 14 and a. steel shell 17. The horizontal portions 16<a> may form one unbroken portion if desired. A circulation of the metal in the crucible is produced which results in a concave surface. A furnace for re-heating ingots and open at both ends is shown in Fig. 15.

Abstract: 1,176,998. Stretching fleece. CARL FREUDENBERG. 22 May, 1967 [21 May, 1966], No. 23701/67. Headings DID and D1N. A method of stretching a fleece uniformly comprises passing resilient needles through the fleece into contact with an abutment, by engagement with which the needles are flexed backwards, the needles while flexed being moved over the abutment and carrying the fleece with them to a point in their travel at which they cease to make contact with the abutment and spring forward dragging fibres with them. Apparatus suitable for carrying out the method comprises resilient needles 4 mounted in a continuously rotating roller 2, the needles being flexed backwards by contact with an abutment in the form of a roller 3 which may be freely rotatable or driven at a slower speed than the roller 2. A conveyor belt 1 feeds the initial thick fleece 5 to the needles 4. In an alternative embodiment, the abutment is in the form of an endless belt and the resilient needles are mounted in an endless belt. In a further embodiment, the needles are mounted in a board which performs a cyclic movement. The stretched fleece thus formed can then be impregnated to form a bonded non-woven fabric.

Abstract: 1,114,845. Feeding coal. SOLAR THOMSON ENGINEERING CO. Ltd. 3 June, 1965 [2 Oct., 1964], No. 23803/65. Heading B8S. Coal is fed to the hopper 22 of a furnace from shoot 37 by means of endless conveyer 10 which discharges the coal through rubber valve seats 24, 23. The passage of the coal therethrough is governed by the vertical reciprocation of a member 25 which is effected by the rotation of cam 29 via linkage 27, 26. Link 27 carries switch 32 so that when the member 25 engages the coal in hopper 22 at a predetermined level, the relative movement between cam 29 and arm 27 operates the switch to stop conveyer 10 and prevent further feed. A timer operates every twelve hours to switch on conveyer 10 to fill the hopper. In a modification it is arranged that the feed should be cut off when the member 25 is at its lowest point so that the valve is then closed and " burn-back " is not then possible.
