Title: Improvements in textile winding machines
IPC: B65H54/52
Filed: 1957-02-09
Abstract: 837,685. Winding yarns. HOLT Ltd., T., HOLT, F., and LEE, G. May 9, 1958 [Feb. 9, 1957], No. 4496/57. Class 120(2) Textile winding machine of the type in which the yarn package is driven by frictional contact with a driving roll and including a pivotally mounted weight influenced cone holder, has means for driving the traverse cam in synchronism with the cone holder; means for imparting a positive initial direct drive to the cone holder until sufficient thickness 'of yarn has been built up on the cone-holder to afford the necessary frictional grip on the driving roll; solenoid operated means for breaking the positive drive at a predetermined time; means for knocking off the winding machine when a predetermined diameter of package is reached and for lifting the package out of driving contact with the driving roll. In the embodiment shown 10 indicates a cone holder mounted in anti-friction bearings 11, 12 in arms 13, 14 pivotally mounted on shaft 15. The arm 14 is hollow and carries a chain drive to the driving spindle 24 of the cone holder 10 from the drive shaft 28. Mounted on shaft 28 with freedom for turning movement relative thereto is a sprocket wheel 31 driven by chain 32 from an electric motor. The chain 32 also drives a sprocket wheel 36 which through gear wheels 39 and 40 drives the shaft 41 of the winding drum 42. Mounted on shaft 28 is one element of a sliding coupling 43 the other element of which is formed in the sprocket wheel 31. The coupling 43 is slidable by means of a lever 44 pivoted at 45 and normally holding the coupling 'inoperative by means of spring 46. The lever 44 is connected by a link 47 to solenoid 48 which when energized at the commencement of winding pulls the lever 44 to clutch the wheel 31 to the shaft 28 whereby rotary motion is transmitted to the shaft 28 and the cone holder 10 is driven through wheel 27, chain 26 and wheel 25. Also mounted on shaft 28 is a further wheel 49 which through chain 50, wheel 51 and gear wheels 55, 56 and 59 drives the shaft 60 of traverse cam 61. When a pre-determined thickness of yarn on the package is reached a microswitch located in the path of movement of the pivoted arm 14 is tripped and deenergizes the solenoid 48 whereby the spring 46 pulls the lever 44 to de-clutch the wheel 31. The drive to the cone holder 10 is then taken up by the winding drum 42. The drive to the traverse cam 61 then comes from the cone holder 10 by way of wheel 25 chain 26 and wheel 27 driving shaft 28. As the diameter of the package increases the arms 13, 14 lift against the action of weights 69 and pin 66 rides up the slotted lever 62. When the package reaches a predetermined size the pin 62 registers with slot 67 and lever 62 moves under the action of spring 65 to contact switch 68 which cuts-off the motor drive. A step 671 in slot 67 lifts the package out of contact with the winding drum 42.

Title: Production of acrylic acid esters
Filed: 1958-02-12
Abstract: Acrylic acid esters are obtained by the reaction of acetylene and carbon monoxide with alcohols or phenols at elevated temperature and under increased pressure in the presence of catalytic amounts of a carbonylation catalyst containing a carbonyl-forming metal and halogen and small amounts of a heavy metal or a compound of the same in which the reaction is carried out in the absence of an organic solvent but in the presence of a small amount of a compound containing the grouping -C(O)OH, wherein water is included in the initial reaction mixture whereby acrylic acid is formed in the course of the reaction and functions as the compound containing the -C(O)OH grouping.  The water can be supplied to the reaction mixture separately or mixed with the alcohol or phenol and it is preferred to use about 4 to 12% of water with reference to the amount by weight of the alcohol or phenol used.  Reaction temperatures are generally between 100 DEG  and 250 DEG  C. and the partial pressure of the acetylene should preferably be between 10 and 80 atmospheres.  The specific alcohols, phenols, and catalysts which may be used are the same as in the parent Specification.  Examples are given for the production of (1) butyl acrylate, using a mixture of nickel bromide and cuprous iodide with and without zinc bromide as catalyst; (2) ethyl acrylate using a mixture of nickel bromide and copper bromide (or cuprous iodide) as catalyst, and (3) isobutyl acrylate using a mixture of nickel bromide and copper bromide as catalyst.  A small amount of acrylic acid is recovered in each case in addition to the ester.

IPC: B21B35/08
Filed: 1952-02-21
Abstract: 727,731. Rolling; drawing. VICKERS-ARMSTRONGS, Ltd. May 20, 1953 [Feb. 21, 1952], No. 4609/52. Class 83 (4). A group control mechanism for a wire - drawing machine or a reversible rolling mill for metal strip &c. comprises a displaceable gate 16, Fig. 1, to which rods 1, 2, 3 controlling the drives for the various machine parts are selectively locked and moved in accordance with chosen displacements of the gate for given operations. In a strip rolling mill described in Specifications 727,732 and 727,733 having the rolls and coiler drums driven through hydraulic pumpmotor combinations controlled for direction and speed by swash-plates actuated from the rods 1, 2, 3, the rods are selected, actuated and set from a remote control panel C according to the required direction and speed of rolling and given ratio of strip reduction. For any given operation a selector switch S brings any selected combination of the control rods 1, 2, 3 into locking engagement with the gate 16 by actuating solenoids 33 which rotate the rods to bring projection 26 into engagement with recesses 29 in the gate. According to the required direction of rolling the gate 16 is then moved up or down by a nut 44 driven in either direction by a motor 49 under the control of a reversing switch P1. Compensation for strip reduction during rolling is provided by variable ratio linkages 83, 84, Fig. 2, coupled between the control rods 1, 3 for the coiler drums and the pump motor control rods 7, 9. A reversing switch P4 controlling a motor 105 varies the linkage ratio to the required degree by moving slides 93 carrying pivot-pins 96 interconnecting slots 87, 88 in the linkage arm 83, 84. An hydraulic ram 118 and lever system 113, 114 set in one of two positions according to the direction of reeling automatically selects the appropriate coiler to which the compensation is to be applied. Cams A and B engaging switches A1, B2 control solenoids for introducing stall tension in the work to prevent slackness before rolling commences in each direction.

Title: Improvements relating to automatic tracking circuits for radar and to pulse generating circuits suitable for use therein
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: G01S13/66
Filed: 1953-02-21
Abstract: 763,576. Pulse radar. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 22, 1954 [Feb. 21, 1953], No. 4887/53. Class 40(7) Pulses for gating radar echoes are produced by combining a waveform 1 with its inverse 2 to provide a waveform 3 having cusps corresponding to the intersections of waveforms 1 and 2. As the radar aerial rotates through # a magslip M produces an output which is applied to demodulator D to provide sin (# - #1), where #1 is the predicted bearing. This waveform is rectified at D1 and its inverse at D2, to provide an input to an amplifier A2 following the more negative of the two waveforms. However, waveforms corresponding to (R - R1) where R is of sawtooth form synchronized with the pulse transmission and R1 is a D.C. voltage proportnoial to the predicted range, and its inverse are rectified at D3, D4, so that the amplifier A2 in fact follows the most negative of four waveforms, with a waveform 7. Clipping levels 5, 6, in the amplifier A2 produce pulses 7a to gate the radar echoes at G. The echo signals passed by the gate G are fed to modulating circuits X1, X2, and integrating circuits S1, S2, S3, to predict the timing of the next gating pulse so that the centre of the gate may receive the next echo. Specifications 761,853 and 763,575 are referred to.

Title: Sonic sounding apparatus
IPC: B06B1/04
Filed: 1949-02-23
Abstract: 666,263. Echo-sounding and distancemeasuring apparatus. BENDIX AVIATION CORPORATION. Feb. 23, 1949. [May 25, 1948] No. 4966/49. Class 118 (ii). A recording echo-sounder wherein sonic waves (including waves outside the audible frequency range) are transmitted in response to electric waves generated on the closure of a control circuit comprises brush means mounted on the recording-stylus moving means co-operating with fixed conductive segments to form a switch for closure of said control circuit and also to energize said stylus in response to the reception of reflected sonic waves. Electrolytic recording paper 15, Fig. 4, is wound from right to left by a small electric motor 28 driving sprockets 21 engaging the holes 22. A tensioned helical spring 40 is so tapered that it exerts a substantially uniform restraining force to keep the paper 15 flat against the backing plate 31. The stylus 32 is fixed to a frame 49 pivoted on a rubber block 51 secured to the belt 33 driven by motor 42 to pass downwardly in front of, and upwardly behind, the paper 15. The side of the frame 49 opposite from the stylus 32 carries a brush 47 which, during the useful part of its travel, makes contact with a strip 52 whereby electric signals may.be fed to the stylus 32. A small segment 63 is mounted near the top end of strip 52 and is insulated therefrom by member 64, but is temporarily connected thereto as brush 47 traverses the junction. In Fig. 8 the control box or recorder casing 10 is represented by the dotted rectangle, a remote transducer 82 being connected by a cable 81 to an inductance 80, tuned by the inherent capacities shown dotted. A thyratron 76 is normally biassed off by a battery 94 but as the brush 47, in its travel, connects segment 63 to 52 a positive pulse due to condenser 91 charging from H.T. supply 78 renders the thyratron temporarily conductive to discharge condenser 79 and thereby shock-excite the tuned inductance 80. Besides causing a short train of sonic waves to be emitted by transducer 82, the electric oscillations are passed via amplifier 85 to segment 52, and the stylus 32 makes a mark for the datum trace 71. On receipt of an echo by transducer 82 the resultant electric wave is amplified and fed to stylus 32, which has travelled downward in the meantime, and a mark is added to the trade 72 representative of the echo time and hence of the distance to be measured.

Abstract: 416,783. Mercury-vapour lamps &c. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Winninghoff, W. J. ; 407, Clark Street, South Orange, New Jersey, U.S.A.) Feb. 20, 1933, No. 5190. Convention date, Feb. 19, 1932. [Class 39 (i).] A vapour-arc tube 1, Fig. 3, is provided at one end with a vaporizable cathode and at the opposite end with two anode chambers 14 which connect with the tube 1 through tubular constrictions 15 and the axes of which lie at an angle to the axis of the tube in a plane determined by this axis and a horizontal line perpendicular thereto. Each anode chamber 14 contains an anode 17 supported on a lead 18 and the lead is surrounded by a sleeve 16 flared outwardly at its inner end. The constrictions 15 reduce the flow of positive ions towards each anode during the part of each cycle when it is inactive and so reduce anode sputtering, and the sleeves 16 provide a long surface path for leakage between the anodes, part of this path being shielded from sputtered particles. Short-circuiting of the anodes is thus avoided and starting of the arc facilitated. The cathode comprises a small quantity of mercury filling a well at the bottom of a bulb 4 and the shielded lead to this well passes vertically downwards from a cap 7 at the top of the bulb. A cap 13 is connected to a starting band comprising overlapping tinfoil sheets on the outside of the bulb 4. A lead-in wire inside, but not connected to, the cap 13 is used only when the lamp is treated during its manufacture by operating it in a vertical position. An irregular mercury meniscus facilitating starting is obtained by fritting granular material, such as that known under the Registered Trade Mark "Carborundum," to the inner surface of the bulb 4 by the method described in Specification 377,573, (Group XXIII]. The bulb 4 is painted black to conceal movements of the cathode hot-spot and improve heat radiation. In the complete lamp, Fig. 1, a housing 3 at the back of the reflector 2 contains a supply transformer, ballast resistances and a starting circuit (Fig. 2, not shown) of the kind described in the Specification 406,413, the starting band on the bulb 4 being connected through a condenser to a circuit including a double-wave rectifier, a mercury-switch and an inductance. The leads 35 to the electrodes are passed through the reflector and end in sockets screwing on to caps on the lamp. Each socket comprises an insulating housing 33, Fig. 7, with a screwthreaded lining 34 and is rotatable on the lead 35 to which a contact 36 is soldered. The cathode cap 7 engages an aperture in the reflector to prevent rotation of the arc tube in the reflector. The sockets connected to the anodes decrease the escape of heat from the chambers and so prevent condensation of mercury therein. The ballast resistances (Fig. 6, not shown) are of iron wire wound on a helically-grooved vitreous spool and are protected by a metal cover frictionally fitting on to a flange on the spool.
