Title: Process for forming plastic solutions and incorporating solid filling material therein
IPC: B29B7/88
Filed: 1944-04-14
Abstract: Solid filler material is incorporated in plastics, for example, cellulosic plastics and phenolic-aldehyde resins, by forming a solution of the plastic, forcibly circulating the solution in a confined path while introducing the filler, <PICT:0577920/IV/1> admitting air to the solution along with the filler, and evaporating solvent from the solution.  The filler may be subjected to a grinding action in the solution, for example, by means of the gear pump used to circulate the mixture.  The solution of the plastic may be prepared by circulating the solvent in a confined path and introducing the plastic and continuing the circulation until the plastic is dissolved.  In an example, a solvent such as acetone, alcohol, or ether-alcohol from the tank 11 is run into the mixing vessel 10 and then caused to circulate through pipe-lines 14 and 29 by means of the gear pump 22.  The plasticiser and then cellulose acetate are introduced into the system through the hopper 21, and when the latter is dissolved the filler, for example, lead carbonate or iron oxide, is introduced in the same manner.  Due to the suction caused by the pump, air is drawn into the system together with the filler, and the excess gases escape through the pipe 30 and are condensed in 32.  When dispersion is complete the excess of solvent is withdrawn from the system by means of the pump 31 and condensed.

Abstract: 1380924 Helical-scan type recorders RCA CORPORATION 10 March 1972 [16 March 1971] 6965/71 Heading G5R [Also in Division G3] In a helical scan recording/reproducing system, mistracking of the rotary heads owing to the stretching of the tape as it passes around the head's drum is counteracted by placing the associated stationary control head on/adjacent the drum at the position where the stretching has reached half the total value; since the stretching varies non-linearly with distance between the points at which the tape initially contacts/finally leave the drum, e.g. points 14, 16, in the arrangement shown, the control head 18 must be placed at a position other than the "geometric mean" position 19. The control signals in the longitudinal track 17, Fig. 1b, are used to control the rotary heads in conventional manner (Fig. 2, not shown). The control head may be on either face of the tape, as discussed with reference to Figs. 8, 9 (not shown).

Abstract: 575,858. Brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., CADMAN, N. G., and PETER, L. H. April 18, 1944, No. 7158. [Class 103 (i)] In a compressed-air braking-system, the air vented from the brake cylinders 8 when the brakes are released, is passed to a chamber 5 in direct communication with the suction of the continuously running air-compressor 1, the chamber 5 being normally kept by the compressor at a relatively low pressure, the compressor thus being normally unloaded. The reservoir 2 is connected by a pipe 16 to a bellows member 14 which is expanded against the action of a spring 15 to close a valve 13. If, due to loss of air from the system, the reservoir pressure falls, the valve 13 lifts and air is admitted through the filter 18 and pipes 17, 4 to the compressor. The valve 13 closes when the pressure is restored. The pedal-operated control valve 7 admits air to the cylinders 8, or vents the cylinders to the chamber 5 which has a relief valve 11 which operates if the pressure in the chamber exceeds, say, 5 lbs. per square inch.

Title: Reducing unwanted modulation in a communication system
IPC: H04N5/217
Filed: 1972-02-16
Abstract: 1362131 Television POST OFFICE 31 Jan 1973 [16 Feb 1972] 7222/72 Heading H4F To reduce unwanted amplitude modulation of a communications signal, e.g. that on the output video signal of a television camera operating at 60 fields per second, but viewing a scene illuminated by lighting varying at a mains rate of 100 c./s., i.e. twice mains frequency, the modulated signal is fed to an analogue divider circuit 1 for division by the modulation signal (input 10) derived from the divider output via a signal level-e.g. black level-clamp 3, a high gain amplifier 6 and a filter 7. The modulations of the video signal f(t) can be represented by a multiplying factor A (1 + m Sin wt), w being the modulating frequency, such that the modulation can be removed by the division of the modulated signal by the factor. The modulation frequency is extracted by the filter 7 which is a commutating N-path filter passing 100 c./s. and its harmonics. The third harmonic 300 c./s., being the 5th harmonic of the field rate is present and thus has to be rejected by a twin-T band stop filter 13 (an elliptical filter also being possible). Components introduced by. the sampling in filter 7 are rejected by a 4th order Butterworth filter 8. The signal Sin wt so extracted has the bias signal A added to it by bias amplitude control circuit 9. The divider circuit comprises an operational amplifier 15 having a trans-conductance multiplier 14 in its feedback loop.

[Class 60.] Driving and feed devices; gauges. - The grinding-wheel of a machine for repetition work is returned a f t e r each operation by a pawl and ratchet device so that its surface irrespective of wear, is at a con s t a n t distance from that of the finished article The feed-screw is operated by hand, or by rotation of a shaft 11 by a ratchet wheel 10, pawl 9, and links 7, 8 from a crank disc 6, which at given intervals is rotated through 360‹. Ratchet wheels 14, 15 keyed to the shaft 11 are engaged by pawls 17, 16 on a freely mounted disc 18. During the feed the pawl 16 abuts against a stop 21 thereby stopping the disc 18, but the pawl is lifted by a cam surface 21a from engagement with the ratchet teeth to permit further feeding of the tool to compensate for its wear, until, when the predetermined size is reached, a controlling finger resting on the work stops the disc 6. An adjustable stop 22 is positioned to engage the pawl 17 on the return movement of the disc 18 and ratchet wheels, such movement thus being a constant determined by the stops 21, 22. A device for causing the feed to vary progressively from a coarse feed to a series of constant fine feeds comprises a follower 29 engaging a cam surface on the disc 18, and varying the number of ratchet teeth exposed on the disc 10 by a shutter 24. A modification is described in which this device is omitted. In a further modification the disengageable pawl and ratchet device 16, 15 is replaced by yieldable friction discs.

Filed: 1966-02-18
Abstract: 1,129,128. Measuring gas concentration electrically. AUERGESELLSCHAFT, G.m.b.H. Feb. 18, 1966 [Feb. 19, 1965; Feb. 22, 1965], No.7341/66. Heading G1N. In a circuit for measuring the concentration of a combustible gas in a mixture, of the type comprising a Wheatstone bridge circuit having a heated detector resistor treated with a catalyst and an untreated reference resistor, ambiguity of measurement is avoided by the provision of an additional heated resistor exposed to the mixture but not connected in the arms of the bridge, this resistor causing an indication to be given when the concentration exceeds a predetermined value. The indication given by meter 9 can normally be interpreted as either a low or a high concentration of gas so the additional resistor 13, and a resistor 14 not exposed to the mixture, are connected in parallel (as shown) or series Fig.4 (not shown), with the energizing source U B  . A proportion of the voltage drop across 14 is applied to transistor 17 which conducts when a predetermined concentration has been reached. As a result the current through meter 9 is subsequently increased and a maximum indication is shown for any concentration above the predetermined value. Element 20 is either a resistor or a visual or audible alarm. The circuit may be modified by connecting the emitter-collector path of transistor 17, in series with an alarm device, directly across source U B .

Filed: 1937-03-12
Abstract: <PICT:0497414/III/1> Liquid products, e.g. oils, are obtained by forcing coal &c. in suspension in a liquid which is a good conductor of heat, e.g. water through a heated receptacle, which it fills completely, into an enclosure at reduced pressure where the liquid products formed are vaporized instantaneously and subsequently condensed. Pulverized coal formed into a pasty suspension with water in a tank 1 is forced through a steel coil 4, heated by a furnace 5 into an insulated tower 6.  The vapours formed are led off through line 7 to condensers and a semi-coke is withdrawn from a hopper 8. The process is applicable to all carbonaceous, mineral or organic solid, fluid or semi-fluid materials, e.g. lignite, bituminous schists, peat, cannel coal, torbanite, tars.  Substances promoting the stability of the suspension, e.g. oils, alkalis, acids, may be incorporated therewith.

Title: Transistorised electron beam deflection circuits and protection means therefor
IPC: H04N3/18
Filed: 1964-02-21
Abstract: 1,047,651. Transistor sawtooth-generating circuits. RADIO CORPORATION OF AMERICA. Feb. 21, 1964 [March 8, 1963], No. 7366/64. Heading H3T. [Also in Division H2] In a circuit, e.g. a television line output circuit, comprising a normally conducting transistor which is periodically rendered non- conducting by the application of input pulses thereto whereby a train of voltage pulses is produced in the output circuit of the transistor but wherein the output circuit is also subject to random large-amplitude pulses which could damage the transistor, a rectifier circuit is connected to said output circuit to develop a voltage related to said train of voltage pulses, there being protective means associated with the rectifier circuit which is operative in response to said random pulses to protect the transistor from their effects. In the line output stage of a television receiver comprising transistor 39, damping diode 52 and capacitors 49, 51, the scanning coils 47 being connected via terminals H across the capacitor 49, the breakdown of diode 59 can produce large amplitude pulses to appear in the output circuit of the transistor 39, which in the absence of protective arrangements would damage the transistor. To provide protection a further rectifier circuit comprising diode 53, capacitor 54 and non-linear resistor 56 whose resistance decreases as the voltage applied thereto increases is coupled to the collector of transistor 39. While the circuit is operating normally, the flyback pulses appearing at the collector of transistor 39 are rectified to produce a voltage across capacitor 54 which may be used to energize preceding video circuits and also be applied to the focusing electrode of the cathode-ray tube. The magnitude of this voltage is such that non-linear resistor 56 does not greatly load the circuit; however, should a large amplitude pulse appear at the collector of transistor 39, due for example to a breakdown of diode 61, the resistance of elements 56 falls to damp the pulse and reduce its amplitude to a level in which the transistor is not damaged. Additional non-linear resistors 36 and 45 are also provided to protect pre-amplifier transistor 28 and the base-emitter circuit of transistor 39. Element 36 is similar to element 56 and protects the transistor 28 from largeamplitude pulses appearing at its collector. Element 45, shown as an incandescent lamp, has a resistance which increases with current so limiting base current flow in transistor 39. The non-linear resistor 56 may be replaced by a Zener diode or a neon bulb. A fuse 44 provides further protection in the event of a continuous breakdown of the diode 59.
