Title: Method and apparatus for obtaining frequency marker pips on wobbulated generators
IPC: H03B23/00
Filed: 1970-10-30
Abstract: 1328552 Generating marker pips for a wobbulator UZINELE ELECTRONICA 30 Oct 1970 [30 Oct 1969] 51818/70 Heading G1U In order to generate marker pulses, the swept signal 1 of a wobbulator, is mixed 2, 13 with signals 3, 14 having fixed frequencies equal to the frequencies of the two ends of the range, namely 28-45 Mc/s, over which the wobbulator signal is swept, and the resulting signals, each of which covers the range 0-17 Mc/s but in opposite directions, are applied, after amplification 4, 15, to two sets of tuned circuits 5-8 and 16-19, the outputs of which are rectified, 9-12 and 20-13, and applied to common shaping circuits 24, 25, to produce the desired marker pulses 26. As a consequence of this method, it is only necessary for the tuned circuits to be tunable over the range 0-8¢ Mc/s in order to be able to produce marker pips anywhere over the whole range of the wobbulator signal.

Abstract: 1,202,255. Extruding pipes and rods. PRECISION CONCRETE EXTRUSION CORP. 16 Nov., 1967, No. 52152/67. Heading B5A. Rods or pipes of cementitious material, having shaped ends, are made by feeding the material to a chamber having front and rear profiled end walls, removing the front wall after the chamber has been filled, continuing the feed so as to force the material out of the chamber through the now open front end, stopping the feed when the desired length has been extruded and finally pushing the rear end wall through the chamber to eject the finished article. In the described embodiment, material from a hopper 11 is fed via screw 12 and tubes 18 and 19 to a trough 96 where it is introduced by screw 20 into an extrusion chamber 10. The chamber comprises a movable base pallet 26, a pivoted front end wall 25 and a rear end wall 21 movable through the chamber by a suitable piston and cylinder mechanism. Located within the chamber is a non-rotatable mandrel mounted upon a shaft passing through the screw 20 behind which mandrel is located a set of rotating blades. In operation, the material fed into the chamber is distributed therein by the blades. After the chamber has been filled and the material forced against the end walls, the front end wall is pivoted downwardly, the continuing feed causing a length of material 1 having a shaped front end to be extruded from the chamber. The pallet 26 is synchronously forwarded to support the length and after termination of the feed, the rear end wall is moved through the chamber to completely eject the article after which said wall is retracted. The ejected article is removed upon the pallet, a new pallet substituted, the front end wall pivoted back into position and a new cycle initiated.

Abstract: 1419972 Stretching apparatus J D McCALL 23 Nov 1972 54228/72 Heading B5B Thermoplastic film is uniaxially stretched by pulling the film away from the nip of restraining rolls whilst heating the film to soften it. The major part of the heating zone is either within the nip of the restraining rolls or within the area from the nip to a plane extending transversely to the film and tangential to the nip rolls. The heating is uniform across the film throughout the entire heating zone. When the film 11 is heated at the nip, nip roller 16 may be internally heated by means of fluid passing through from inlet 26 to outlet 28 (not shown). When the film is heated after the nip the heater may take the form of a bar 48 placed close to the nip. This bar is preferably a wedge shape, the point 52 being thrust almost into the nip, and having a flat bottom surface 50 close to the film. By inclining the bar 48 at a slight angle α the nip may be shielded from convection currents. When a heating bar is used the roll 16 may be cooled by fluid passing internally through it. Preferably roll 16 has a non-resilient surface and roll 18 a resilient one. Pulling rolls 40 and 42 may also be non- resilient and resilient respectively and 40 may also be cooled. The process is illustrated for polyvinyl alcohol and is stated to give a uniform stretching.

A switch and store circuit comprises solid state switching means (e.g. a field-effect transistor) for switching a control signal (e.g. an analogue voltage) from control apparatus (e.g. a digital computer) to charge storage means, and electromechanical switching means (e.g. a relay) which is energized by the control apparatus and which, in the event of a malfunction of the control apparatus, prevents charge leakage from the charge storage means. The two switching means are in series. Opening of the relay due to the malfunction not only prevents charge leakage but may also cause charging from a reference voltage source. A plurality of arrangements as above may feed control signals from the computer to a controlled process, digital signals derived from the latter being fed to the computer.

To measure the height of material in several containers 20-22, each has a cable 10 fixed to the floor, passing over a pulley 12 and tensioned by weight 13. Under the control of a central processor 17 each cable in turn is pulsed by cam 14, the resulting mechanical wave passing down cable 10 and being reflected at the material surface. Sensor 15 which may be an inductive proximity switch or a resistance strain gauge senses the passage of the transmitted and received pulses and passes them to pulse shaper 30. The squared pulses set and reset bi-stable 31, which enables digital counter 34 (counting impulses from clock 33), and also trigger analogue integrator 35. Control 32 orders the switching of the inputs and outputs of multiplexer 19. The counter 34 and integrator 35 are switched in turn to digital indicators 26-28 and analogue meters 36-38. Also provided are alarms, e.g. lamps, horns or relays which are acutated if the measured levels reach predetermined values. The counter 34 and integrator 35 may count up from zero to indicate the height above the material or down from a maximum value to indicate the actual material height. In a modified arrangement, the cable is at least partly ferro-magnetic and an alternating magnetic field of variable frequency excites the cable. The frequency of the field which causes resonance of the cable is thus a measure of the free cable length. Alternatively, the cable is conducting and situated in a fixed magnetic field. The cable is then excited by a variable frequency current. Furthermore, instead of measuring the transit time of a pulse, the amplitudes of the transmitted and received pulses may be compared to provide an indication of the free cable length.

In an echo suppressor the speech band is regarded as comprising a number of sub-bands and the signals arriving over the receiving channel 6 are analysed by filters 31-36 and control relays 41-46 to suppress the transmission of the sub-bands momentarily present in the received signal, by opening contacts 21-26 in series with the appropriate ones of the filters 11-16. In a modification Fig. 2 (not shown) the receiving channel includes filters similar to 11- 16 controlled by the relays 41-46 so that only the sub-bands which are suppressed in the outgoing channel are allowed to pass in the incoming channel. In Fig. 3 (not shown), a detector is arranged to detect simultaneous talking by both parties to allot interleaved subbands to the two directions. To economize in the filter requirement a single set of filters may be employed with the individual filters switched between the incoming and outgoing channels.
