Title: Method and apparatus for feeding homogenised thermoplastic material with a uniform flow front
IPC: C03B5/187
Filed: 1966-04-13
Abstract: 1,139,577. Glass manufacture. CORNING GLASS WORKS. 13 April, 1966 [19 April, 1965], No. 16252/66. Heading C1M. [Also in Division F4] Molten glass is homogenized whilst being flowed along a horizontal forehearth by being subjected to the action of a pump 16 which forces the glass downwards through a cylindrical path 18 into a confined horizontal passage 20 below the forehearth and a pump 26 which forces the glass upwards in a confined oval path 22 from the confined passage 20 to the horizontal path of the forehearth, the glass then having a uniform flow front. The pump 16 is centrally situated in the cylindrical well 18 communicating with the passage 20. The pump 26 comprises two counter-rotating stirrers having their axes along the major axis of the oval well 22. The counter-rotating stirrers send the glass through two helical paths such that high spots form along the forehearth sidewalls and such that the two paths merge to give a uniform parabolic flow path. The method is particularly useful where coloured or other additions are to be added to the glass within the forehearth.

Title: Improvements relating to Tape Winding Machines.
Inventor: TURNER DAVID
IPC: H02K15/10
Filed: 1967-04-10
Abstract: 1,154,065. Taping conductors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 3 Jan., 1968 [10 April, 1967], No. 16353/67. Heading B8G. Conductors C, Fig. 1, are drawn from reels D1, D2 and wound on to a former F of non- circular shape, the former F rotating about an an axis A. The conductors C pass through a revolving centrally apertured carrier H on which is an arm holding a reel of tape T. As the carrier rotates the tape T is wound around the conductors C. The shape of the former F is such that if it rotates at constant speed, the rate at which the conductors C pass through the carrier H continuously varies and therefore, to obtain a constant pitch of the helical winding of the tape T, the rate of rotation of the carrier H should vary so as to be in constant proportion to the speed of movement of the conductors C. This is achieved, according to the invention, by using a belt or chain assembly, Fig. 2, the belt or chain passing over sprockets S1 S2 that simulate the shape of the former F and rotate about the axis A. A sprocket S4 is geared to the carrier H to rotate it, and a dancer sprocket S5 takes up any slack in the chain as the sprockets S1 S2 rotate about the axis A.

Abstract: 691,930. Spooling thread. DUNLOP RUBBER CO., Ltd. June 20, 1951 [July 1, 1950], No. 16478/50. Class 120(ii) A spool winding machine in which the spool may be driven by a roller 2 engaging the spool between its flanges comprises a traverse bar 11, a thread guide 12 frictionally and slidably mounted thereon and means for reciprocating the bar, said means comprising a traverse member' 8 reciprocated, e.g. by a helical cam sleeve 9, an angularly adjustable track 14 rigidly mounted on the frame of the machine and a lever 10 rotatably mounted at 21 between its ends on the member 8 and being pivotally attached at 23 to the bar 11 whilst its other end, e.g. having a freely rotatable roller 13, is slidable in the track 14, whereby the length of stroke of the bar 11 relative to the member 8 may be adjusted by the angular setting of the track 14 with reference to the bar 11. The track 14 may be locked in the adjusted position by a clamping screw 30. The slidable connection of the thread guide 12 with the traverse bar 11 allows the guide, upon contact with the spool flange, to come to rest, the bar still moving until the end of its traverse.

Title: Hydrostatic torque-measuring apparatus
IPC: G01L3/14
Filed: 1965-04-20
Abstract: 1,106,110. Dynamometers. W. REINERS and G. WIGGERMANN [trading as REINERS UND WIGGERMANN]. April 20, 1965 [April 20, 1964], No. 16554/65. Heading G1W. The torque-measuring coupling described in Specification 879, 478 is modified by providing the driving hub 1 and driven housing 2 with centrifuge wheels 1d, 2d dish-shaped to receive edges 7c turned in from the outer walls 7b of entrapping chambers 15, 15' in the stationary fluid transmitter 7. When installed with the hub 1 vertical the effective discharge opening 16 will be below the baffle edges formed by the inner rims of the edges 7c. The housing 2 is attached to a driven member by means of a flange 2a, but the driving member 4 is received and secured inside the hub 1, thus reducing the overall length of the coupling, which is further reduced by forming one of the entrapping chambers to overlap the bearings 3. Fluid from a reservoir or pump fed through a flexible conduit 8 to the transmitter 7 passes into an annular groove 10, along bores 11 and through admission slots 12 to displacement cells 5, 5', Fig. 2 thence through bores 13, a cavity 14 and bearings 3 to the centrifuge wheel 2d and chamber 15 to the discharged through peripheral openings 16. The transmitter 7 is'mounted on the hub 1 in a plain bearing 6 and any fluid issuing axially from the bearing 6 is thrown by the centrifuge wheels 1d 2d into the chamber 15', 15. When relative motion is too slow for centrifugal forces to suffice, escape of fluid through the clearances between the rotary and stationary parts is hindered by peripheral knife edges 18 on the hub and housing parts 1c, 2c. A reversible flanged collector nozzle 17 can be attached to the transmitter 7 with its oblique discharge pipe 17a directed downwardly irrespective of the attitude of the coupling. To obtain more accurate measurements of lower torques some of the displacement cells 5, 5' Fig. 2, which expand and contact with relative movement between the hub 1 and housing 2, can be put out of action by adjusting selected pistons 20 to increase the pressure to a range in which it can be more accurately measured. A modified bearing 25 with plastic sealing rings 26 is described, Fig. 4 (not shown).

Title: Fm receivers
IPC: H04B1/10
Filed: 1975-04-22
Abstract: 1496567 Detecting multipath reception in FM receiver SONY CORP 22 April 1975 [1 May 1974] 16634/75 Heading H4L Arrangements are provided in an F.M. receiver by means of which low frequency signals are produced in response to the presence of amplitude modulated components in a received F.M. broadcast signal due to multipath reception thereof. These low frequency signals are selectively applicable to the loud-speaker in the receiver in place of the normal amplified audio signal derived from the selected F.M. broadcast signal to audibly indicate the existence of multipath reception. If such an indication is derived, the receiver aerial may be adjusted until the low frequency note is minimized. The receiver conventionally incorporates R.F. stage 3, mixer 4 I.F. stages 6, 7, 8, F.M. detector 9, audio amplifier 10 and loud-speaker 11. The signal from the I.F. stage 7 is applied to a diode detector stage 12 which produces low frequency signals when amplitude modulation of the F.M. signals, indicating multipath reception, exists. The output of this stage may be fed via a selector switch 13 to the loud-speaker. With a high gain F.M. receiver, the limiting effect of the R.F. and I.F. stages may prevent the circuit 12 from producing low frequency signals. To avoid this, when the selector switch 13 is set in the monitoring position, as shown, the output from the diode circuit 12, after smoothing at 14, is fed via switch 15, ganged to 13, to the gain control inputs of the I.F. amplifiers 6, 7, to reduce their gain. At the same time, R.F. amplifier 3 may be short circuited by switch 16, also ganged to 13. In normal use of the F.M. receiver the switches 15, 16 are opened.
