Patent GB-1045776-A (GB)
Title: Improvements in or relating to continuous spinning and twisting machines
IPC: D01H1/00
Filed: 1964-04-17
Abstract: A Spinning &c., apparatus comprises at least two driven pots containing slubbings obtained from a carding-engine, feeding-means for entraining the slubbings so that they are twisted between the pots and the means, and take-up means at which the threads are twisted and collected internally or externally as a doubled yarn. The slubbings may be of asbestos and be doubled with reinforcing threads of metal or glass.  The pots Fig. 1 (not shown), have rotating heads 13, whereby as the slubbings are withdrawn by feed-rollers 21, 24, 29, they are converted into threads 19, the two threads being brought together by a guide 20.  Thread 25 from a bobbin 26 also passes to the feed-rollers via the guide, and threads from bobbins 28 pass directly to the rollers.  The combined threads 30 are taken up on a ring-spindle 40 when the traveller is of selected weight.  The rollers serve to equalize the component lengths in the doubled yarn and may stretch the threads; the upper rollers bear on the lower ones by gravity or resiliently-applied force.  Break-detectors 96-100 are provided and feeler 95 Fig. 5 (not shown), determines when the take-up bobbin is filled.  A control system for bringing the pots, rollers and the take-up spindle into and out of operation, is described (Fig. 5 not shown).  Each pot has a lid 10 which can be lowered by a handle 107 to be held against the pull of a spring 102 by an electromagnet 103 energized by manually closing a switch.  The pots are driven when clutches 14 are engaged and can be braked at 18; the take-up spindle has a brake 32 and the upper roller can be moved on or off the driven roller 21 by rocking arms 79.  These parts are operatively linked to a lever 51 operated by a pedal 50 against a spring 49.  A second lever 81 carries a resilient pin 112; when pedal 50 is depressed, lever 51 displaces the pin for it to spring back and hold the lever in depressed position when the pedal is released.  To release the lever, the lever 81 is rocked to withdraw the pin 112 when a pedal 80 is depressed or an electromagnet 85 energized.  In operation, with the pot-lids closed and the electromagnets 103 energized, pedal 50 is depressed.  The brakes 18, 32 are released, the clutches 14 are engaged and roller 24 is lowered. Electromagnet 86 is inoperative so that the pin holds the lever 50 in depressed position.  These conditions are maintained until the receiving bobbin is filled or until a thread breaks or runs out, when one or other of the detectors 95....100 completes a circuit to operate a relay to light an indicator and energize electromagnet 86 so that pin 112 is withdrawn to unlock lever 51 which accordingly rises and stops the associated parts.  When a break occurring in one of the pots is repaired, slight pressure is exerted on the pedal 50 to lightly engage the drive and retension the silver.  Other arrangements of the pots are described.

Title: Improvements in or relating to circuit-arrangements for amplifying ultra-high-frequency oscillations
IPC: H03F3/52
Filed: 1948-06-15
Abstract: 643,946. Valve amplifying circuits. PHILIPS ELECTRICAL, Ltd. June 15, 1948, No. 16082. Convention date, June 18, 1947. [Class 40 (v)] The damping of the input circuit 5, Fig. 1, of a grounded grid amplifier 1 is reduced by a reaction condenser 7 between anode and cathode, while self oscillation is prevented by damping the output circuit 6 by coupling it to the input of a similar stage 10, having output terminals 17. In Fig. 3, the tube 34 is a secondary emission tube and the auxiliary cathode 18 is connected for high-frequencies to the grounded grid. The resistive and reactive parts 24, 23 of the reaction path may be separately adjusted, and the output circuit 6 is damped by being coupled to the input of a further stage (not shown). In a further modification (Fig. 4, not shown), the input, output and reaction circuits are each in the form of a Lecher system of three concentric conductors with adjustable bridges to form impedance transformers.

Title: Improvements in automatic fidelity control for radio reception
IPC: H03G5/26
Filed: 1938-05-30
Abstract: 504,230. Valve amplifying circuits. HAZELTINE CORPORATION. May 30, 1938, No. 16134. Convention date, June 18, 1937. [Class 40 (v)] In a band-pass selector with aperiodic output and input circuits and directive coupling in both forward and backward directions, the back-coupling is less frequency discriminative than the terminal circuits so as to be regenerative only at the limits of the pass-band. The two coupling means are adjustable preferably in such a manner that the gain of the system as a whole is unaffected. The Figure shows a superheterodyne receiver having an intermediate frequency amplifier 14 and signal and automatic volume control detector 15 and also a frequency modulation detector 22 and rectifier 23 as described in Specification 504,229. The audiofrequency amplifier 26 includes a trap circuit 35, 36 tuned to 10 kc. in the output and a valve 27 producing negative feedback. The bias of the valves 26, 27 is controlled from the rectifier 23 preferably in such a manner that the band width passed is adjusted without variation of gain. Regenerative feedback is produced at lower audio frequencies by the inductance of the transformer primary 32 and condenser 30 and at higher audio frequencies by the trap circuit 35, 36 and the condenser 29. At frequencies above that of the trap circuit this gives a 90‹ lead to the voltage which is counterbalanced by the phase lag produced by condenser 29 so that at these frequencies degeneration is produced.

Title: Improvements in or relating to apparatus for bending flat glass
Inventor: BAKER HENRY WELLSTOOD
IPC: C03B35/20
Filed: 1949-06-17
Abstract: 664,104. Bending glass. PILKINGTON BROS., Ltd. June 1, 1950 [June 17, 1949], No. 16229/49. Class 56 In apparatus for bending flat glass sheets, the tongs 41 which grip the top edge of the glass are suspended from the lower members 14 of hingedly connected open frames 20 which themselves are suspended from an overhead bar 21. The tong bar formed by the frames 20 is acted on by the laterally reciprocating templates which determine the curvature imparted to the glass, the tong bar being flexed synchronously with and similarly to the development of the bend in the glass. The suspension of the tong bar from the bar 21 includes relatively angularly movable coaxial members 25, 28 at each neutral axis, and the middle frame 19 has a post 29 engaged by a fork 36 carried by one of the templates, and the post is connected to the bar 21 by levers 31, 32 and pivots 33, 42 whereby endwise movement of the tong bar as a whole is prevented. The arrangement shown maintains the tong bar in the upright position but the arms of the pivots may be slightly inclined and the middle section of the tong bar may be made to rise and fall slightly so that the weight of glass taken by each tong is approximately the same after bending as it was before bending. The tong bar may be straightened by hand after a bending operation or by a pair of straight reshaping templates.

IPC: B29C48/09
Filed: 1954-06-02
Abstract: 788,439. Moulding tubes. STEWARTS & LLOYDS, Ltd. June 2, 1954, No. 16297/54. Class 87(2). [Also in Group XXII] Tubes of polyethylene &c. are formed to rectangular, triangular, D-shape, pear shape &c. sections by drawing through a die comprising a sizing part b<SP>1</SP>, Fig. 10, of the required final section which is merged into by a conical frustum entry portion a<SP>1</SP>. The major diameter D of the cone frustum is slightly larger than the outer diameter of the stock and the minor diameter s equals the smallest cross dimension of the product, the merge being obtained by removing proud edges at the intersection so that at any position 13, 17 along the die, a face b, Figs. 13, 17, forms a tangent to the curve of the conical frustum from a point at a corner of the final section. In operation the tangents b progressively close with the equivalent of a toggle action to force the material towards the corners. The tubes may be pulled or pushed through the die as by hydraulic cylinders and in one example the tube is alternately pushed by a hydraulic cylinder 3a, Fig 3, while gripped by a cross-head 5 and then pulled by a hydraulic cylinder 4 while gripped by a cross-head 6. The movement of the cylinders is so arranged that the work is continuously moved. In another example the tube is drawn through the die by the dog carriage of a drawbench. The tube is gripped internally by four pegs 2, Fig. 6, which extend radially towards the four corners of the square section die and are forced outwards by a conical mandrel 1 on the dog carriage to dig into the internal surface of the tube. The pegs are carried in a sleeve 3 which is moved longitudinally over the mandrel by a handle 6 through a link 5 to engage or release the grip. Springs 9 retract the pegs 2 when released and a stop 8 on the mandrel 1 engaged by the sleeve 3 limits the engagement of the pegs 2 with the work. The die is built up from a number of segments 6 adjustable by shims 5 and located between a thrust plate 7 and a cover plate 8.
