Abstract: 561,304. Audible signalling apparatus. FOUNTAIN, Ltd., G. R., HOULGATE, H. J., and WHEELER, G. C. Nov. 4, 1942, No. 15558. [Class 118 (ii)] [Also in Group XL] Apparatus for producing an audible warning or alarm having a changing pitch comprises a resistance-capacity back-coupled valve generator feeding a sound-reproducing device such as a loud-speaker, the pitch being varied by a bias applied to one or more of the resistance elements to vary its impedance. As shown in Fig. 1, the generator comprises a back-coupled valve V with a phasing network, consisting of series capacities C1, C2 ... and shunt resistances R1, R2 ... connected between the plate and the grid. To enable variation of pitch to be effected by a control voltage, one or more of the resistances is constituted as shown in Fig. 2 by a pair of reversely-connected rectifiers or other non-linear elements, to which the control voltage and a bias voltage are applied across a condenser C5. The control voltage may have a period of several seconds and may be derived from a circuit similar to that used for the audiofrequency oscillation. Alternatively, an intermittent warning may be provided by deriving the control voltage from a multi-vibrator or like circuit, Fig. 5 (not shown). Two audiofrequency oscillators operating at different frequencies and controlled simultaneously by a single control voltage may be arranged to feed a single sound-reproducing device, Fig. 3 (not shown). Specification 561,322, [Group XL], is referred to.

Title: Automatic control for photosensitive tube

IPC: H04N5/235
Filed: 1959-05-07
Abstract: 955,821. Television; cathode-ray tube circuits. EPSYLON RESEARCH & DEVELOPMENT CO. Ltd. May 4, 1960 [May 7, 1959], No. 15717/59. Headings H4F and H4T. A control circuit for a television camera tube or a photo-multiplier tube comprises a video amplifier to which the tube output is fed, a clamp circuit to give a reference voltage at the output of the video amplifier, a rectifier to rectify the amplifier output, means to compare the rectified voltage and a reference voltage to produce a difference voltage, and a D.C. amplifier, controlled by the difference voltage, whose output current controls the tube. In the case of a television camera, the tube 11 gives a video output which is amplified in unit 12. Clamp 13 provides a D.C. zero reference for the amplified signals, which are fed to valve V1. The video output for utilization purposes is taken from the anode while video from the cathode passes to a second valve V2 whose output is passed to a peak-to-peak rectifier 15. The output of rectifier 15 is compared to a reference voltage from source RV1 and the difference fed to an R.C. network to correct the phase of the difference voltage when passed to a D.C. amplifier valve V3. The output of V3 varies the target voltage in accordance with changes in the average level of incident radiation, so that the video output level at terminal 14 is substantially constant. A capacitor C5 is associated with V3 to make use of the Miller effect to obviate the need for large smoothing capacity in the grid. Where a photomultiplier is to be controlled, for example as in a transparency flying spot scanning system, the camera tube 11 is replaced by the photomultiplier, Fig. 2 (not shown), and the output of V3 is connected to a power supply which supplies the dynodes of the photomultiplier. The remainder of the circuitry is the same as that described above.

Abstract: 1386634 A bag-in-box packaging METRIC PACKAGING Ltd 6 July 1973 [6 April 1972] 15830/72 Headings B8C and B8P A bag-in-box container comprises a plastics bag in an outer casing with a mouth of the bag secured to a flap of the casing so that, with the casing erected in box-like form, the flap can be moved pivotally about a fold to bring the mouth from a position within the casing to a position outside the casing. When the container is intended to contain free flowing-powders, &c., the plastics bag is in the form of an envelope and has a plastics neck, spout, or gland, formed integrally therewith, or secured thereto, and provided with a closure tap, cap, or plug. The latter may be a force fit in an aperture in the flap or, secured in the aperture by a connecting piece, alternatively, the aperture may be a slit to retain the bag neck which can be opened by the insertion of a rigid tube. Alternatively, the mouth of the bag may be secured to the flap by an adhesive. As shown, a blank, Fig. 1, has its left, and right, hand edges secured together to form a tubular blank around a plastics bag, not shown, which has its neck extending through an aperture in the flap 5. After the tubular blank has been expanded to rectangular section by the filling of the plastics bag, the top flanges of the tubular blank are folded inwards and secured in overlapping relationship, the bottom flaps then being folded inwards in the sequence 6, 4, 3,1, as shown in Fig. 2. The flap 5, with the bag mouth, is then pushed inside the box and the flap 2 is bent upwards to close the aperture left by the flap 5 and is then secured in position. In use the whole of the flap 2, or only a perforated central portion, is torn away so that the flap 5 with the bag mouth can be withdrawn from the container. In a blank, Figs. 3, 4, the mouth of the plastics bag extends through an aperture in the flap 5, the bottom flaps, after the filling of the bag, being folded in the sequence 6, 2, 4, 1, 3. In the blank, Figs. 5-7, not shown, the mouth of the bag extends through an aperture in a separate flap (6) which is adhered to the box immediately behind a hinged locking flap (5). The casing is formed of cardboard, or fibreboard, of integral, or laminated, section, and may be in the form of a box already erected.

Filed: 1935-05-31
Abstract: 457,538. Crepe threads of regenerated cellulose. DREYFUS, H., 22, Hanover Square, London. May 31, 1935, No. 15866. [Class 120 (iii)] Threads consisting of filaments of regenerated cellulose are given a crepe twist, and during the insertion of at least the last part of the crepe twist, the threads are passed through a substantially closed chamber containing steam, preferably moist, so that twist is inserted while the threads are under the influence of the steam. In a modification, the threads are given a crÛpe twist, at least the last part of which is inserted while the threads are under the influence of hot water. Any suitable crÛpe twisting device may be employed. When using steam in the process, the thread may be drawn off upwardly over the end of a rotating package through a guide in line with the axis of the spindle and passed through a small chamber situated vertically above the spindle. The chamber is provided with holes top and bottom for the passage of the thread, and an inlet for the steam. The chamber suitably consists of a horizontal pipe provided with a number of pairs of porcelain or stainless steel eyes, one eye being at the top and the other at the bottom, so that a number of threads may be twisted and steamed simultaneously. In order to assure the presence of the desired moisture, the dry steam may be passed through water, or the thread may be wetted with water before it enters the steaming device. When hot water is used during the twisting, the thread coming from the twisting spindle passes upwardly through a receptacle containing the hot water, through a hole or tube of fine bore in the bottom of the receptacle. A preferred method of working is to apply up to 10 to 30 turns per inch without the steam or hot water, and then to complete the crepe twisting in the presence of the steam or hot water. The process may be applied to the treatment of threads obtained from viscose or cuprammonium cellulose solutions, or to saponified cellulose ester threads. According to the Provisional Specification, other softening agents than steam and hot water may be applied during the crepe twisting, e.g. aqueous solutions of thiocyanates, zinc chloride, acetic acid, or formic acid, vapours of organic substances with or without steam, or warm or cold water if desired together with wetting agents and under normal or raised pressures.
