Title: Machine for the continuous treatment of textile webs,preferably with a treating agent in gaseous and vapour form at positive or negative gauge pressure
IPC: D06B23/18
Filed: 1962-06-12
Abstract: 964, 379. Textile treating apparatus. JOH. KLEINEWEFERS SOHNE. June 12, 1962 [June 10, 1961], No. 22440/62. Heading D1L. A machine for the continuous treatment of textile webs, particularly with gases and vapours, comprises a closed treatment vessel having slots for the passage of the web into and out of it, each slot being defined by at least one bar having at least one resilient sealing roller associated therewith so as to seal the slot relatively to the exterior of the vessel, thereby permitting the maintenance of an elevated or reduced pressure in the vessel, relative to the exterior. In the embodiment shown textile material 1 is guided between two resilient rotatable rollers 2 into a lead-in nozzle 3 and thence into treatment chamber 4. It is led out from chamber 4 through nozzle 6 and between a pair of resilient rollers 7. Heating coils 8 are installed in the base of chamber 4 and are surrounded by treating liquid, a sieve 9 being fitted above the liquid to avoid spattering of the textile materiaL Alternatively the lower guide rollers 5 may dip into the liquid bath. The rollers in each roller pair 2 and 7 are urged against each other by pressure rollers 10 which may be of barrel shape. The lead in nozzle 3 is formed by a bar 26 which is wedged shaped in cross-section and has parts shaped to conform in part to the surface of rollers 2. The bar 26 is formed with a slot 12 through which the material is led and is wider than the rollers 2. Projections 13 at the sides of slot 12 are so thin in the region of plane 24 that they are lost in the flexible deformation of the rollers 2. In the case of the lead in nozzle the projection 13 protrude well beyond the line of contact of rollers 2 but with the nozzle 6 they do not extend beyond the contact line of rollers 7. In a second embodiment, (Fig. 8, not shown), the lead-in and lead-out nozzles are formed by one roller in contact with a suitable bar having a slot therein for the textile material to pass through and of less width than the roller. In this embodiment also the material is kept in contact with an endless belt whilst passing into and through the treatment chamber and means are provided for lubricating the belt for ease of sliding through the nozzle slots.

Title: Improvements in or relating to automatic gain control circuit arrangements for television receivers
Inventor: MOTHERSOLE PETER LEONARD
IPC: H04N5/50
Filed: 1956-07-20
Abstract: 809,377. Automatic gain control. MULLARD RADIO VALVE CO. Ltd. July 20, 1956, No. 22561/56. Class 40 (5). In a television receiver provided with an automatic gain control (A.G.C.) circuit of the " keyed " type, means are provided to prevent the receiver being paralysed when a strong signal is suddenly applied to it. The receiver comprises gain-controlled stages 1, 2, Fig. 4, video detector 3 and amplifier 4, from the anode circuit of which video signal is applied to the cathode of the picture tube and to a sync. separator. Video signal is also applied to a gate circuit 6 which is normally closed, but is driven open during the " back porch periods by keying pulses derived from either the line scanning or the synchronizing circuits of the receiver. The output of the gate circuit 6 comprises a train of pulses of height proportional to the amplitude of the black level, and is applied to a rectifier 8, the output of which is smoothed by R.C. network 15, 10, 11, 12 and applied to the A.G.C. line. To prevent paralysis of the receiver when a strong signal is suddenly applied, i.e. before the A.G.C. has time to operate, the condenser 15 is returned to the join of condenser 14 and resistor 13, which are in series across the anode circuit of valve 4; if valve 4 is suddenly overloaded, the corresponding drop in anode potential is communicated to the A.G.C. line via condensers 14, 15, as a negative pulse. The gain is thereby reduced, removing the overload; the circuit returns to normal operation with a time-constant, determined by resistor 13 and condenser 14, greater than a frame period. In a modification (Fig. 5, not shown), a noise limiting diode is interposed between resistor 13 and the anode of valve 4; in this case the recovery time of the circuit can be made shorter. In an alternative arrangement applicable to a switch-tuned receiver, a further switch 19, Fig. 6, is ganged to the station selector switch, having additional contacts p, q, &c. interposed between contacts a, b, &c. corresponding to tuning positions. Thus, in changing stations there is momentarily applied to the A.G.C. line a strong negative potential from source S which may comprise the grid of the line output valve.

Title: Electronic apparatus for radiation exposure control,more especially for photographic printing apparatus
IPC: G01J1/42
Filed: 1963-06-07
Abstract: 1,019,339. Photo-electric exposure control. AGFA A. G. June 7, 1963 [June 8, 1962], No. 22875/63. Heading G1A. [Also in Division H3] Exposure in a photographic printer is controlled to be greater for less dense negatives and smaller for denser negatives, by mixing the output of a photo-sensitive timing device receiving the printing light with the output of a standard timing device and utilising the mixed signal to control an exposure terminating device. In operation, closure of a main switch 43 applies a positive potential to a line 11 through a rectifier circuit 9. A thyratron 33 immediately strikes to energize a relay 34 which controls normally open contacts 34a, b and c and normally closed contacts 34d and e. Closure of contact 34a extinguishes the thyratron 33 but maintains energization of the relay 34. The apparatus is then in readiness condition. For a printing operation, normally closed spring loaded switch 35 is opened thus de-energizing relay 34 and thereby opening contacts 34a, b and c and closing contacts 34d and e causing the printing lamp 42 to be switched on. Photo-multiplier 20 receives light from the lamp 42 through a photographic negative and charging of capacitors 18 and 19 begins. The potential at tapping 32 of a mixing potentiometer 31 rises until it reaches a value at which the thyratron 33 strikes to energize the relay 34 thus ending the printing operation by opening the contact 34e. The tapped potential depends upon the signals from both the thyratrons so that the exposure given is between "constant time" and "constant total quantity of radiation". The constant time thyratron may be replaced by a motor driven potentiometer. Initial calibration may be accomplished by adjustment of the potentiometer 31 and resistors 40 and 21. Printing material speed may be taken into account by extending or reducing the charging times of the capacitors 18 and 19 in a corresponding manner by adjusting the ganged resistors 21 and 40. In a modification, Fig. 3, (not shown) the potentiometer 31 is connected between the cathodes of the valves 24, 26, their anodes being connected to the line 11. The photomultiplier may be replaced by a photocell having no photomultiplication. The apparatus may be used for controlling X-ray apparatus in which case the photomultiplier is replaced by an X-ray detector.
