Title: Glass batch feeding apparatus and method
Inventor: ZELLERS JAMES THOMAS
IPC: C03B3/00
Filed: 1964-10-23
Abstract: <PICT:1015110/C1/1> <PICT:1015110/C1/2> A method of feeding raw glass batch and cullet to a glass melting furnace, including rotating a compartmented elongated cylindrical surface in a counterclockwise direction about its longitudinal axis and depositing the raw glass making materials into the compartments as they pass a stationary feed source, is characterized by separately depositing the cullet upon the raw batch in the said compartments, and thereafter delivering said materials in a continuous layer upon molten glass in the charging end of a furnace.  The raw materials are fed to a hopper 28 having a front wall, opposite side walls and an inclined rear wall, an inclined partition substantially parallel to the rear wall dividing the hopper 28 into a large front compartment 29 for raw batch and a smaller rear compartment 30 for cullet.  The compartments 29 and 30 have outlets 57, 65 at their lower ends in close proximity to a feed roll 37 divided into compartments 41. Raw batch is fed from a hopper 26 into the front compartment 29 and from thence through opening 57 into compartments 41 of the counterclockwise rotating roll 37.  A bin 100 holds cullet which is delivered through at least two outlets in its base on to as many individual endless-belt type conveyers 101. These convey the cullet into the rear compartment 30. Cullet is discharged through opening 65 on to the batch material already in compartments 41 of roll 37.  The cullet is forced and compacted against the batch by an adjustable gauge plate 68.  Each conveyor 101 is individually controllable so that different quantities of cullet can be fed across the width of the compartment 30 and thus across the charging end of the furnace.  A channel member 66 near the opening 65 of the rear compartment provides means for passing a coolant such as water to prevent the cullet from softening whilst still in the hopper 28.  Also the core 38 of the feed roll 37 is so constructed that a coolant under pressure, such as water, may be passed therethrough.

Title: Method and Apparatus for Manufacturing Bulky Crimped Yarn from Synthetic Resin Films.
IPC: B26F1/24
Filed: 1966-09-29
Abstract: 1,151,076. Film fibrillation; cutting film. CHORI CO. Ltd. 29 Sept., 1966 [31 Jan., 1966; 24 Feb., 1966], No. 43656/66. Headings B4B and B5B. [Also in Division D1] In the manufacture of crimped yarn from reticulated film, a synthetic resin film is split to form uniformly arranged slits therein. Fibrous strand formed from the split film is fed through a pair of rollers to press it against a moving belt thereby to impart uniform crimp which is subsequently set by heat treatment. As shown, a stretched film 1 passes between an elastic roll 2 or belt (not shown) and a splitter 3 pressed thereagainst whereby the film is cut at lengths equal to that of blade edges on the splitter, thus forming the slits 4. The blade line may be staggered or zig-zag and/or the pattern may be varied with alternating sharp and dull slits by vibrating the roll 2 (as by sonic, compressedair or electromechanical means). A cutter for slitting the film into suitable widths at the same time as splitting may be positioned coaxially with the splitter and the split film is then extended sideways to form a network structure, Fig. 13 (not shown). The split film passes through guide rolls 9 to a twister 10 and the resultant strand is buckled as it is pressed against a belt 12 the surface speed of which is less than the peripheral speed of nip rollers 11, 11<SP>1</SP>. Crimped yarn results when the strand conveyed by belt 12 from space 16 is heattreated in the zone between an internally heated support roll 13 and a cover 15. The synthetic films may be those produced by melting, dry or wet processing from high molecular polymers, including polyethylene, polypropylene, poly-(butene-1), poly-(pentene- 1) and like polymers of olefins such as 3- methylbutene-1, 4-methylpentene-1, and polyvinyl alcohol, polyvinyl chloride, polyamides, polyesters, polyacrylonitrile. The splitter 3, Figs. 4 and 5, comprises cutter members, each having peripheral arcuate blade edges 5, secured on a shaft 7 in such manner that the edges are staggered from one another to form a spiral edge line along the periphery of the splitter body. In another embodiment, Fig. 6 (not shown), the splitter, having a spiral or linear blade line, is formed by a stacked assembly of cutter members each comprising a blade disc 32, Fig. 8, having edges 33 and circumferential notches 34, 35, and a washer member 37, Fig. 10, having radial and arcuate cuts 38 and 39 leading to holes 40, combined as shown in Fig. 12 so that each tongue section 41 engages with cut 34 to form a cutter element.

Filed: 1968-09-13
Abstract: 1286455 Pulse radar THORN ELECTRICAL COMPONENTS Ltd 9 Sept 1969 [13 Sept 1968] 43781/68 Heading H4D [Also in Division G1] Visual range in fog is determined by transmitting a pulsed parallel beam of radiation (light or radar) and integrating the intensity of the reflected radiation so that visual range can be determined. The transmitter/receiver unit 17 in the system shown in Fig. 2 is rotatably mounted and comprises a laser 10 which produces pulses of light of 10<SP>-9</SP> sec. duration formed by mirror 11 and lenses 12, 13 into a broad parallel beam. Beam splitter 14 deflects the reflected light through lens 15 on to photomultiplier 16. The output of photomultiplier 16 passes through gate 24 to integrator 25 whose output is compared with a preset value which takes account of the threshold visibility necessary for safe operation in comparator 26. When the integrated value reaches the preset value gate control circuit 27 operates to close gate 24. The time that the gate was open is used in determining the line of sight visibility x (FOG). By resolution and comparison of the geometrical distance x (GEOM) the mounting can be rotated by motor 20 and the output of resolver 23 will give attitude and runway visual range. A full mathematical discussion is given. In a modification the transmitted radiation is directed vertically upwards and the resulting value of x resolved to the required line of sight, Fig. 4 (not shown). In this arrangement a plurality of units are used and the results processed in a central computer to give a fog pattern picture for the whole area. The circuits of Figs. 5 and 6 (not shown) are used in this last application.

Abstract: 1,207,334. Card readers. TATEISI ELECTRONICS CO. 28 Sept., 1967 [4 Oct., 1966],  No. 44270/67. Heading G4M. A credit card or ticket 1 has timing marks a 0 -a 7 , a direction distinguishing mark b and data marks c, e.g. in 2 out of 5 code, which are sensed by heads 2, a counter 11 is advanced by pulses derived from the timing marks to control the entry of data pulses in bi-stable circuits 13a. .13g, and a comparator diode matrix 14, 16 determines whether the data read conforms with the data effectively stored in semi-permanent form by the matrix, irrespective of the orientation of card 1 on insertion. The card may have magnetic, printed or punched marks, an optional reference mark b, and may be sensed magnetically or photo-electrically In the embodiment shown, heads 2a, 2b sense the upper surface of the card 1, and heads 2c, 2d sense the lower surface. If the card is inserted forwards as in (A) or (C), timing pulses are obtained from OR gate 5a and data pulses from OR gate 5b. The a 0  pulse sets 6a and opens 9a, 9c to pass subsequent timing pulses to counter 11 and the data pulses to gates 12 so that the data including the b pulse is entered in 13a-13f in the forward direction. If the card 1 is inserted backwards as in (B) or (C), OR gate 5b produces timing pulses and OR gate 5a the data pulses. In this case 6b is set by the a 7  pulse which occurs first, 9b and 9d are opened and the data and b pulses are entered in 13b-13g in the reverse order. For this reason two sets of diode AND gates 14, 16 are provided in the comparator matrix corresponding to forward and reverse entry. A passenger barrier for example may be operated if the data read is found to be " valid." Modifcations.-The timing marks a 1 -a 6  may be aligned with marks b, c and an extra timing mark a 8  provided, Fig. 1B (not shown), counter 11 then having an additional stage and stages 1-7 controlling gates 12a-12g. The marks a and b, c may be recorded centrally but on opposite faces of the card, Fig. 3b (not shown), or two heads capable of sensing marks on either surface may be provided, Fig. 4 (not shown) so that only two heads are required and gates 5a, 5b can be omitted. By arranging for the outputs of counter 11 to control two sets of gates 12, the data pulses can be entered in the bi-stable circuits 13 in the forward direction irrespective of the direction in which the card is inserted so that only one set of diode AND gates is required in the comparator matrix Fig. 5 (not shown). The data marks c may be in 3-out-of 7 code. Counter 11 may be reversible, the direction of counting and thus of entry of the data bits in bi-stable circuits 13 being controlled by circuit 13a which is set when the b mark is sensed before the data marks.
