Apparatus for making tubular sheathing for cables comprising means for supplying metal sheet to a tube-forming bending device, a welding device to weld together adjacent edges of the bent sheet to form tubing and means to draw the welded tubing from the machine is characterized in that during the drawing of the tube in an axial direction a groove forming member is urged by a device rotating about the axis of the tube against the inside wall of the tube so that it is helically corrugated. Metal sheet 40, bent up into tubular form 41 as it is fed through bending means 6 and longitudinally seam welded by discs 4, is pulled over corrugating means by a holder 14 secured to a carriage 19 pulled along by an endless chain 10 driven by means 7. When the carriage 19 reaches a stop 20 the machine stops and a length of tubing may be sawn off. The end of the tubing gripped by the holder 14 may be given a conical form. The corrugating means comprises a fixed tube 26 inside the formed tubing in which is rotated by a gear 24 a hollow shaft 28 to which is secured a hollow head 29. A rod 32 axially slidable within the shaft 28 carries within the head 29 a bearing block 30 formed with a recess 35 to accommodate a ball 31. On axial movement of the shaft 28 by a cam 25 the ball 31 is pushed outwardly through an aperture in the head 29 so that as the tubing is drawn over the rotating head 29 a helical corrugation 37 is pressed outwardly from the tubing by the ball 31. More than one ball may be used.

In a television receiver, line synchronizing pulses 1 are supplied to a phase discriminator 2 which also receives an input from the line oscillator 4, the output of the discriminator being smoothed at 5 and via a circuit 6 controlling the oscillator 4. The pulses 1 are also supplied to a coincidence circuit 9 together with a reference signal from the oscillator 4 so that the gate 8 is opened only when the oscillator 4 is out of synchronism, to supply pulses 1 direct to the oscillator 4. Frame synchronizing pulses 12 are supplied to a phase discriminator 13 to control the frame oscillator 14 via a smoothing circuit 16, an output from the frame oscillator being fed back via a phase-inverting circuit 15 to the discriminator 13. The output from 13 is a negative pulse having a duration dependent upon the phase error. Inverted frame synchronizing pulses 18 are integrated at 19 and control pulses 20 are supplied via a controllable attenuator 21 to the oscillator 14. The attenuator 21 is controlled by a coincidence circuit 22 receiving as one input the pulses 12 and as the other a reference signal from the oscillator 14, maximum attenuation taking place when the oscillator 14 is in synchronism. In addition, a portion of the output voltage of the line phase discriminator 2 is applied via the smoothing circuit 16 to assist in synchronizing the frame oscillator 14. This is stated to prevent picture roll when one or more frame synchronizing pulses are missing, and to minimize the effect of interference pulses.

Abstract: 976, 362. Automatic temperature control systems. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 24 1961 [April 25, 1960], No. 14805/61. Heading G3R. In an automatic control system wherein a variable quantity such as temperature is to be held at a determined value, the rate of change on one side of this value is made slowly whereas the rate of change on the other side is made rapidly. A liquid flowing in a line 23 is heated in furnace coils 24 by a gas/air mixture through pipes 26, 28 respectively. Assuming that excess air is provided initially, a controller 3 tends to reduce the air supply thus increasing the temperature as measured by M and reducing the differential and a reference signal I. At the same time the gas flow will also be reduced slowly due to temperature increase until a point is reached where the temperature tends to drop wherein both controllers 2, 3 will act rapidly to increase the gas and air supplies with a given range. The arrangement may also be controlled by smoke density.

Abstract: 663,422. Electrostatic switches. BRUSH DEVELOPMENT CO. June 3, 1949. [June 12, 1948] No. 14947/49. Class 38 (v). [Also in Groups XXXV and XL (b)] An electrostatic relay comprises an elongated element of electro-mechanically sensitive dielectric material convoluted into a space the largest dimension of which is a small fraction of the length of the elongated element. Fig. 1 shows a relay having a helical piezo-electric element 11 which operates by bending mounted on a frame 12, 13, 14, 16, 17, the lower end being fixed to the frame at 18, and the upper end being fixed to a yoke 26 on an arm 24 coupled through a driving spindle 22 to an insulating arm 27 carrying a contact 28 for engaging a fixed contact 31. A voltage applied to terminals 49, 51 connected to opposite electrodes of element 11, causes the element to bend, giving a large cumulative displacement at the upper end of the helix for operating the contact arm 27. The frame members 13, 14, 16 are covered with felt or like fabric. The helix 11 may be formed of two strips of electroded piezo-electric material cemented together and arranged so that on the application of a voltage, one strip expands while the other contracts, such as the titanate members described in Specifications 648,403 and 648,404 [both in Group XL (b)]. Alternatively the helix may be formed from a hollow flattened tube of piezo-electric material having one internal electrode, and a pair of opposite external electrodes, for example as described in Specification 663,423 [Group XL (b)]. In the case of titanate elements, they may be continuously polarised by an external source, or they may be pre-polarised during formation of the element. Instead of a helix, a flat spiral element may be used, Figs. 5 and 6 (not shown). In Fig. 7 the element 100 is cut from a piece of piezoelectric material so as to comprise a number of limbs 101 ... 107 joined at alternate ends. One end is fixed at 117, and the electrodes on the sides of the limbs are joined in pairs as shown so that on the application of a voltage at 49, 51, the limbs alternately expand and contract to give an additive displacement of the end 118 relative to the fixed end 117 to operate contacts 119,120. The limbs are guided in comb-like members 122, 123 lined with a resilient fabric. Specifications 659,869, [Group XL (c)], and 663,424, [Group XL (b)], are referred to.

Abstract: 593,468. Coating materials. ALEXANDER, P. Aug. 4, 1944, No. 14963. [Class 93] [Also in Group II] In a method of depositing a coating of a substance having a vapour pressure of at least 1 mm. of 'mercury on a moving support by thermal evaporation in a vacuum, the coating material is vaporised by heating in a container to produce a pressure relatively high in comparison to that in the vacuum chamber which pressure is released gradually to produce a beam of atoms having a relatively high velocity in the direction of the support whereby residual gas molecules are prevented from entering the body of the beam. As shown, the substance 4 is vaporised in a container 3 by a heating element 7, which also maintains the temperature of the vapour, and is forced through a nozzle 12, by virtue of its pressure over that of the vacuum chamber 1, to be deposited on a paper support 2 which is fed from the roll 14 to the roll 15. Any molecules of the residual gas which may encounter the beam are carried by the outer layers and strike the baffles 17. In a modification, Fig. 5 (not shown) the beam is enclosed by shields which have an opening through which any molecules of the residual gas are carried by those portions of the beam which after striking the support obliquely glance off. Various types of nozzle are described, Figs. 3, 7, and 8 (not shown).

The melting zone comprises a screw zone 118 of constant depth, a compression zone 120 of progressively decreasing depth, and a zone (2) of constant depth. with the melting being effected by heat conducted from the heated extruder barrel 72, and also developed fractionally by the unmelted material. The apparatus prevents "surging" of the extruder output which would otherwise arise from unmelted material filling and blocking the downstream end of the melting zone. In the embodiments, some melting of the material may occur in the passage 122, which communicates with the downstream end of the melting zone 100 and with the upstream location, respectively at one or more radial passages 124 and 126. Movement of material along the passage 122 may be facilitated by a stationary screw 130 within the passage 122, and the screw flight 136 of which is of the same hand as that 88 of the screw 123. The screw 130 is fixed by an arbour 132 to the extruder barrel at 134. The amount of material passing along the passage 122 may be throttled by a valve shoulder (142), Fig. 5 (not shown), carried either by the upstream or the downstream end of the screw for respective co-operation with the passages (126) or (124) and adjusted by a threaded mounting of the screw arbour (132). The screw (130) may be absent from the passage (122), Fig. 6 (not shown), and the passage 122, Fig. 7, may be throttled by a valve 164, threadedly mounted in the screw 123 for adjustment and co-operating either with the opening 126, or the opening 124.
