Optical apparatus; electric circuit applications. -A record of the combined sound from several sources is made by converting each source of sound into fluctuating current, combining these currents and recording the variations of the combined current. The current representing each source may be variably amplified and otherwise modified under the control of a telephone in the circuit of the combined current. Each source of sound is collected by a separate transmitter A, B, C, wihich may be portable, and is of the kind described in Specification 180,296 with a mirror arrangement as described in Specification 130,762, [Class 40 (iii), Telegraphs, Electric], the sounds acting on diaphragms connected with the pivoted mirrors 7 so that these reflect the light from sources 5 on to the edge of slits in plates 10 whereby varying amounts of light pass to selenium cells 9 each connected in the grid-filament circuit of a thermionic valve amplifier 2 across which. a resistance. 19 is shunted. The amplified sound from each source is impressed through a transformer 3 on a common circuit 24 which actuates an electromagnetic recorder 25. By the aid of a telephone 26 and variable resistance 27 in parallel in the recorder circuit the effect of the current from each source can be controlled by means of variable resistances 28 across the secondaries of the transformers 3. Further variation in control can be effected when a second amplifier is employed in each circuit by varying the resistance in the grid circuit of the second amplifier. In a modified arrangement, the transformers 3 are dispensed with and the plates of the amplifiers 2 are connected with the filaments through resistances the ends of which are connected with the two branches of the combined circuit. Specification 180,296 is referred to.

Abstract: 627,262. Compound fabrics; multiple-ply paper board. TRIGGS, W. W. (Keyes Fibre Co.). Oct. 9, 1946, No. 30189. [Classes 96 and 140] A resin-fibre article comprises an assembly of superimposed resin-fibre layers hardened and integrated under heat and pressure, the ratio of fibres to resin being greater in certain of the layers than in others to produce layers of relatively high resin content and layers of relatively low resin content which alternate with each other in the assembly, the resin content of the layers of relatively high resin content being such as to bond said layers to the other layers and to furnish at the exposed edges of the article sufficient resin to provide a continuous highly resinous covering encasing the edges of all the layers. It is preferred that a layer of relatively high resin content occurs at each end of the assembly. The article may be produced by suction-die moulding a plurality of fibrous preforms of different resin-fibre composition from aqueous mixtures of fibres (e.g. cellulosic pulp fibres) and synthetic resin (preferably thermosetting), with or without fillers and colouring matter, removing the preforms and drying them, producing the resinous preforms 11 and fibrous preforms 12 (Figs. 1 and 2), assembling a plurality of these in superimposed and alternate order between a pair of heated finishing dies 14 and 15 (Fig. 4) closing the dies with sufficient pressure to compact the assembly to the final article dimension while applying heat to melt the resin and bond together the preform faces and cause the melted resin to extrude at the edges, and confining said extruded resin to cause it to spread and encase the exposed edges of all the preforms within a highly resinous protective covering.

Band; hand actuation; force-transmitting mechanism.-Brake mechanism for the cable laying gear of cable ships comprises gearing by which a brake shaft can be turned for gradually applying and releasing the brake and a clutch device by which the gearing can be disconnected to permit direct and more rapid actuation of the shaft. The shaft i which actuates the band brake g has loosely mounted thereon a sleeve q with a worm wheel p geared to a worm on the shaft of a hand wheel 14. The sleeve q has clutch teeth r for engagement with teeth on a. sleeve t splined on the shaft i. A pair of levers y have their forked ends pivoted at 4, 5 on extensions of the sleeve t and in engagement with an annular groove 1 in the end of the shaft i. As shown the clutch teeth r. s are in engagment and the shaft i can be turned bv the hand wheel 14 to effect a gradual control of the brake. When it is required to turn the shaft more rapidly, the levers y are first moved in the direction of the arrows 17, Fig. 3, thereby sliding the sleeve t to disengage the clutch and are then used to turn the shaft directly. The clutch is held in the position of engagement and disengagement by a spring pin 6 on the sleeve t engaging recesses 12 in the shaft i. Spur gearing with ratchet and pawl locking means may be used instead of worm gearing. The end of the brake band g are connected to the shaft i by nuts l, m working on a right and left handed screw threaded part of the shaft and the band is anchored bv a stud 20 adjustable by a screw 23 and connected by a link 21 to a fixed part e.

Title: Television receiving circuit
IPC: H04N5/10
Filed: 1935-11-02
Abstract: 465,141. Television. RADIOAKT.-GES. D. S. LOEWE. Nov. 2, 1935, No. 30316. Convention date, Nov. 6, 1934. [Class 40 (iii)] A valve 12 in a receiver, synchronized by signals corresponding to white, is coupled to an auxiliary electrode 5 in a cathode-ray tube 4 by an anode circuit 30 giving an effective amplification at the frequency of the linesynchronizing signals such that the effect on the ray of the normal controlling-electrode 3 is overcome and the ray is reduced to zero. The synchronizing-signals are separated from the image signals by the grid-cathode circuit 15, 18, which is coupled through a resistance 28 to the lead 1 traversed by signals representing the image. The grid current is used to obtain both a regulating bias for the associated amplifier and the bias for separating the synchronizing-signals, which are thus of constant amplitude. The anode lead 30 is of low capacity and is taken out through the bulb .of the valve. The value of the blocking-potential in the anode circuit is determined by the bias on a screening-grid 14 and is made independent of the operating level of the bias on the controlling-grid by a suppressing-grid 13.

Filed: 1974-07-24
Abstract: 1442501 Cutting apparatus MASCHINENFABRIK F R NIEPMANN & CO 24 July 1974 [27 July 1973] 30472/74 Heading B4B Apparatus for cutting a printed web 1 of paper, plastics or other material into separate sections comprises a web feed roller 3 which co-operates with a counter-pressure roller 4 and is provided with a cutter 8, a peripheral portion 9 of the feed roller being movable inwardly by an additional contact pressure movement of the counter pressure roller, such movement being controlled by means 17 in dependence on the position of the required cut with respect to the cutter. The counter-pressure roller 4 is mounted on a pivoted lever 10 locked , in a normal contact-pressure position of the latter roller, by means of a bolt 12 actuated by a solenoid 13. During normal feeding of the web, a roller 14 mounted on the lever 10 engages a concentric portion of a cam-disc 15 rotating synchronously with the feed roller 3. A photocell 17 is arranged to monitor printed marks on the web such that if the position of the cut varies from the desired location, the solenoid is actuated thereby releasing the bolt 12 and allowing the roller 4 to be additionally urged against the peripheral portion 9 by a spring 11; the portion 9 is in the form of a resilient cushion. The increased pressure of the roller 4 on the portion 9 has the effect of increasing the effective peripheral length of the feed roller 3 thereby momentarily speeding up the movement of the web. Upon release of the bolt, the lever 10 does not move until the roller 14 is aligned with a recess 16 on the cam disc 15; the depth and length of the disc determines the degree of additional pressure and duration thereof. In order to improve the accuracy of cutting, a second feed roller and counter-pressure roller arrangement 3a, 4a, 11a may be provided. In modifications the resilient cushion 9 may be replaced by a metal or plastics pressure member (18), Fig. 3 (not shown), loaded by a spring (19) or an arcuate member (20), Fig. 4 (not shown), loaded by a spring (21).

Abstract: 1467475 Electron beam magnetic deflecting apparatus VIDEON SA 10 July 1974 [13 July 1973 13 Aug 1973] 30530/74 Heading H1D [Also in Division H4] A device for the deflection and convergence correction of coplanar electron beams in colour TV tubes comprises two pairs of coil windings on a single ferrite core for deflection in two orthogonal directions 0/90 degrees, and four toroidal coils on said or another single ferrite core when the coil windings are toroidal, or an another single core when the coil windings are saddle shaped, and connected in series for dynamic convergence correction and which produce a four-pole field at 45 degrees to the 0/90 degree axes, the field being rotatable by varying the current distribution through the coils, the toroidal coils for convergence correction being each divided into two halves 1, 2, 3, 4 and 1<SP>1</SP>, 2<SP>1</SP>, 3<SP>1</SP>, 4<SP>1</SP>, and located on the core so that the centres of each two diametrically opposite coil halves form an angle α with the 0/90 degree axes and so that one set of coil halves are connected in series and the other halves are in series, both sets being connected in parallel with a correction current source, the current of which is supplied via a current distributing member to the parallel connected sets of coil halves. Ends 8, 9 are connected to a coil 10 about a displaceable ferrite core 12 whereby the currents to the different winding groups may be varied. Generator 6 produces a variable current displacing the beams horizontally and on variation of the almost symmetrical supply in centre tap 11 an angular variation ## of the field occurs. The four-pole field may be considered the superposition of a 45/45 degree field (αcos- (##)), and a 0/90 degrees four pole field (αsin- (##)). Control of the current for oppositely influencing the two outer beams (R, B) is independent of the current distribution control for influencing the rotation of the beams out of the horizontal. The current distribution control may alternatively be as in Fig. 3 (not shown) with potentiometer (13) in place of coil 10, or a group of semi-conductor elements of controllable resistance may be used.
