Title: Improvements in methods and devices for manufacturing plate glass
IPC: C03B13/16
Filed: 1926-05-03
Abstract: 253,494. Bicheroux, M., (Assignee of Reis, L. von). June 11, 1925, [Convention date]. Drawings to Specification. Rolling.-A method of avoiding surface defects in plate glass consists in rolling the plates with shallow flutes on one or both surfaces. The plates are made by passing the molten glass between rollers having circumferential flutings, and the plates so formed are received on conveyor tables which are preferably formed with ribs or flutes at right angles to those on the rollers. Thus the plates make contact with the tables only at small surfaces and transfer of heat from the plates to the tables is minimized.

Abstract: 655,117. Locking levers and rods; ratchet gearing. SCOTT, A. A. H. N. April 28, 1948, No. 11613. Convention date, July 1, 1947. [Class 80(iii)] Releasable locking means for angularly - moveable elements, such as for adjustably securing the handlebar 12, Fig. 2, of a bicycle in a housing 11 fixed to - the steering pillar 10, comprises a pair of rollers (or balls) 16 normally wedged by an interposed spring 17 between a cylin drical sleeve 14, secured to the member 12, and the oval-shaped interior of the member 11, the lower parl of which forms a seating for the the sleeve 14. Levers 19, pivoted on a bolt 23 passing through the member 11 and serving also, with screws 25, to secure cover plates 24, have lugs 20 extending through holes 21 in the member 11 so that, on depression of the levers, the lugs 20 dispace the rollers from wedging position to permit angular adjustment of the member 12. Outward movement of the levers is limited by lugs 26. Alternatively the levers may be replaced by pointed screws threaded in the holes 21, inadvertent movement of the screws being prevented by a spring strip engaging the serrated heads of the screws. Where a reversible ratchet drive is required, as in a boring brace as shown in Fig. 5 where a sleeve 48, integral with the crank handle encircles the chuck shaft 49, one or other of the rollers 16 is released from wedging engagement by rotation in the appropriate direction of a cam sleeve 57 coacting with pointed plungers 54 slidable in the holes 21. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which a brake lever is mounted on a fixed shaft, movement of the lever in one direction being normally prevented by a single spring-pressed wedging roller releasable by a push rod operable by a grip lever pivoted on the brake lever. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to sewing machines
IPC: D05B3/02
Filed: 1931-04-25
Abstract: 363,272. Sewing-machines. UNION SPECIAL-MASCHINENFABRIK GES., 33, Schwabstrasse, Stuttgart, Germany. April 25, 1931, No. 12272. Convention date, April 28, 1930. [Class 112.] Needles, vibrating laterally.-A needle-bar and a thread-carrying looper are moved laterally of the line of feed for laying the stitches to ornament the fabric and a loop-retainer is provided for holding the loop back from the looper. The loop retainer is also moved laterally of the line of feed for maintaining its position relative to the looper. Preferably, a common control member such as a pattern drum, regulates the lateral movement of the needlebar, looper and loop retainer. The needle-bar 3 is carried in the gate 4 and is reciprocated in the usual way by the lever 5, eccentric strap 6 and motor shaft 7. The looper 9 co-operates with the needle 8. The looper carrier 10 is pivoted at 11 to a support 12 which is oscillated by an arm 13 cooperating with a cam 14 on the main shaft 7. This gives the needle-avoiding movement to the looper. The looper carrier is oscillated by a link comprising two sections 15, 17, the section 17 being pivoted to the needle lever 5. The links are pivoted to a crank pin 20 carried by a link 21 pivoted at 22 to an arm 23 carried by a yoke. This yoke carries an arm 25 provided with a roller 27 running in a groove in the pattern cam 28. The cam 28 is detachably connected to a supporting disc 29 which is rotated from the main shaft by gears 31, 32, 33. The arm 25 is connected at 34 to a link 35 which in turn is connected to the needle-bar gate 4. By changing the pattern cam, various designs may be produced on the fabric by the changed direction of the stitches. As the arm 23 is raised or lowered it moves the link sections 15, 17 towards or from a straight line so changing the oscillating position of the looper to maintain its position relative to the needle. The loop retainer 36 is mounted on a carrier fixed to a shaft 38 mounted for oscillation and reciprocation in a bearing lug carried on the bed 1 of the machine. The retainer has an arm 40 which co-operates with a cam 41 on the main shaft 7. This oscillates the shaft 38 and moves the retainer laterally of the needle. The shaft 38 is moved endwise bv an arm 42 mounted to oscillate on a support 43 carried by the bed 1. The outer end of the arm 42 has a head 44 straddling a pin carried by a head 46 attached to the outer end of the shaft 38. The head 44 is mounted on a pin which has a sliding engagement with the arm 42. This arm is fixed to an arm 48 carrying a ball stud 49 which is connected by a link 53 to a ball stud 52 operated by the eccentric strap 51 from the main shaft. The yoke of the arm 23 carries an arm 54 having a ball stud connected with the link 53 so that the pattern cam shifts the working position of the strap 51 and the reciprocating position of the retainer 36 to maintain its position relative to the looper.

Filed: 1951-05-28
Abstract: 699,771. Automatic volume control. PYE, Ltd. May 28, 1952 [May 28, 1951], No. 12451/51. Class 40 (iv). [Also in Group XL (c)] A gain control arrangement comprises a cathode-follower with an attenuator network connected to its cathode and with switching means to render the valve inoperative at will. With the switch S open the valve V1 operates as a cathode-follower having resistances R3, R4 as the cathode load, and the attenuation is small. If switch S is closed a positive bias is applied to the cathode bias resistance R2 such that the valve is cut off. An attenuated signal is then transferred between input and output terminals by the attenuator networks comprising resistances R3, R4 and the grid leak R1; a condenser C2 corrects for the shunting effect of the gridcathode capacity Cgc. The valve may alternatively be rendered non-conductive by biasing the grid negatively, or by switching off the heater. A number of such arrangements, either in cascade or placed between successive pairs of stages in an amplifier, may be provided so as to allow of the signal being attenuated in steps. The arrangement provides for controlling the gain of an amplifier at a remote point and several channels may be controlled simultaneously. It may also be applied to fade-over circuits.

Title: Improvements in the production of artificial filaments
IPC: D01D5/04
Filed: 1932-04-30
Abstract: In apparatus for the production of artificial filaments by the evaporative method, the filtering-device which precedes the spinning jet is <PICT:0400662/IV/1> provided with an internal passage whereby evaporative medium may be passed through the body of the spinning solution contained in the filter.  The evaporative medium heats the spinning solution prior to extrusion.  Some of the evaporative medium which passes through the cell may be led outside the filtering-device.  As shown in the drawing, spinning solution passes down a pipe 4 to a filtering-device 3 wherein it passes through the perforated wall 10 and filter material 9 to the annular space 8, and is extruded from the annular jet 11.  Heated air passes upwardly through the cell and is withdrawn through the pipe 13, some of the air passing through a passage 5 constructed within the filtering-device, while the remainder travels outside the casing 7 and through a gap 15 in a plate 14.  The proportions of air passing externally and internally of the filtering-device are determined by the ratio of the area of the gap 15 to the total area of the passages 6. Shields 16 direct the rising currents of air heated by pipes 17, to the outside of the filter body.  The air passing through the conduit 5 although cooler than that passing externally, still has a considerable heating effect on the spinning solution prior to filtration.  The apparatus may be used for the production of filaments of cellulose acetate or other cellulose ester or of ethyl cellulose or other cellulose ether.  Specification 300,998, [Class 2 (ii), Cellulose &c.], is referred to.  The Provisional Specification describes also the use of a jacket around the filtering-device, or solution-supply pipe, hot air being directed towards and through the jacket in order to heat the solution.  The air for heating the spinning solution may be introduced from the external atmosphere independently of that forming the main current within the cell.  Cold air may be introduced into the cell in the neighbourhood of the jet.
