Title: Improvements in and relating to television receiving apparatus
Inventor: JUSTICE JAMES WILLIAM HENRY
IPC: H04N9/24
Filed: 1958-10-17
Abstract: 919,034. Television. SYLVANIA-THORN COLOUR TELEVISION LABORATORIES Ltd. Oct. 14, 1959 [Oct. 17, 1958], No. 33278/58. Class 40 (3).  Automatic gain control is applied to a photomultiplier tube 10 which receives light from indexing stripes on the screen of a colour picture tube 13 such that variations in the amplitude of the indexing signals produced by the tube 10 as a result of variations in intensity of the scanning beam, due to the signal modulation thereof, or of variations in the intensity of the light received by tube 10 from different parts of the screen, are reduced. The effect of the former variation is reduced by deriving from the combined luminance and chromic signals an automatic gain control signal in generator 40 and utilizing this signal to vary, in a compensating machine, the potential of one or more of the dynodes in the photo-multiplier 10. Alternatively, the gain-control signal may comprise the " M " signal which drives the cathode of the picture tube or it may be derived from a lowpass filter connected to the last dynode of the photo-multiplier (Fig. 2, Prov., not shown). To compensate for variations in light intensity from different parts of the screen a further control signal consisting of the line and frame timebase waveforms combined in suitable proportions with parabolic waveforms derived by integration of the former waveforms is produced and utilized to vary the potential of another of the dynodes of the photo-multiplier. Specification 895,772 is referred to.

Title: Holders for exposed photographic cut films and similar sheets
Inventor: WOODCOCK EDWARD CECIL
IPC: G03B42/04
Filed: 1963-08-22
Abstract: 1,100,681. Feeding sheets. AGFA A.G. 20 Nov., 1964 [22 Aug., 1963], No. 33348/63. Heading B6B. [Also in Division G2] A container 2, 3 set in a light shaft 1a of the housing of a film developing machine has a shaft 7 secured between its side walls, the shaft bearing rotatable hinge lugs 8a to 17a and (8b) to (17b) (Fig. 3, not shown), each pair carrying a hinged flap 18-27, the flaps being parallel to each other. The container is also provided with a pivoted light tight cover 61. When the container is to be loaded away from machine the flaps are outwardly open (Fig. 3). A first film is pushed in through the opening in the wall 2, flap 18 is swung up and held in place by a key 48 which engages a keyway 38 in the lug 8a. During this operation a pawl (59a) (Fig. 2, not shown) is held away from ratchet teeth (49a-j). When all the films have been inserted, the cover 61 is closed, the light tight holder is pushed into the shaft 1a and a lug 63c engages an abutment 66 thus opening the cover 61. A member 57 comes into the path of the core 69 of a solenoid 68 which is energized causing member 57 to move to the right in Fig. 2, and the key 48 to move out of the keyway 47 of the lug 17a thus allowing the flap 27 to fall under gravity (Fig. 1). The film 37 is thereby released and guided between rollers 70, 72 where it raises the roller 72 to open a microswitch 75 thus de-energizing the solenoid 68. The member 57 is released and returns to its original position, while the key 48 is held in the keyway 46 by the action of a pawl (59) engaging teeth (49a-j). As the film leaves the rollers 70, 72 the switch 75 is closed, the solenoid is energized, and the cycle is repeated.

Title: Improved method of and means for curing or drying varnished surfaces on articles of manufacture
IPC: C14C15/00
Filed: 1930-11-06
Abstract: Varnished surfaces of articles, or of fabrics or leather, are dried by exposure, at a distance not greater than fourteen inches, to radiation of wave-lengths in the ultra-violet region from quartz mercury vapour lamps.  Preferably the distance is approximately five inches.  The duration of the treatment is from five to twenty-five minutes, and the varnished articles, fabrics or leather are moved past the bank of lamps on a conveyer.  The process is carried out in a chamber, and provision is made for regulating the temperature and humidity of the air therein, for instance by introducing air conditioned as to temperature and moisture content.  An arrangement of apparatus shown in Fig. 1, comprises a treating chamber 1 in which is disposed a bank of mercury vapour lamps arranged in staggered formation and extending the whole length of the chamber, an air conditioning chamber 19 provided with an electrical heating device 21 and with humidifying apparatus, a blower 20 to circulate the air, and at the other end of the chamber 1 an apparatus 28 for the recovery of fixed nitrogen evolved by the action taking place.  To admit air from outside the system when <PICT:0366571/III/1> <PICT:0366571/III/2> <PICT:0366571/III/3> required, a valve 24 is provided.  A blower 30 extracts the air from the chamber 1, and an alternative connection is provided by the valve 32.  The varnished hides 4, Fig. 5, are stretched on frames 3 which are carried along by chain conveyers 5 in close proximity to the bank of lamps, one conveyer being located on each side of the bank.  The lamps 2, Fig. 2, are supported on movable shelves 13 which are arranged between uprights 12, the shelves and uprights serving to shield the lamps from air currents.

Filed: 1928-11-17
Abstract: 324,453. Heaton, P. St. J., and Radiovisor Parent, Ltd. Nov. 17, 1928. Light radiations, control of apparatus by.-An interrupter or reflector for controlling the illumination of lightsensitive cells comprises a plurality of selective members varying the light admitted to one or more cells. A lamp A, Fig. 1, illuminates light-sensitive cells B, C, the interrupter EH comprising a number of slats arranged as shown, and being capable of movement between lamp and cells. The passage of section EF cuts off all light from C, the rays to B being unaffected; section FG cuts off light from B but admits light to C, while section GH cuts off light from both cells. By using a screen with graduated slat inclination, a progressive change in illumination of a single cell is obtained. In Fig. 3, the slats are pivoted and coupled so that their inclination may be varied simultaneously, position K2, L2 causing total cut off. The interrupter may be replaced by reflecting surfaces N1, N2, Fig. 4, which may be adjustable like the slats in Fig. 3; with this arrangement the cells and lamp are on the same side of the screen, the cells normally being in darkness. The invention may be applied to railway signalling or control. Specification 337,976, [Class 105, Railway signals &c.], is referred to.

Abstract: 652,390. Valve relay circuits. CALVERT, R., SWALE, R. T., TOLE, C. R., and WAYNE KERR LABORATORIES, Ltd. Dec. 24, 1947, No. 34105. [Class 40 (vi)] In order to provide a variable accurate time interval between two events, such as the operation of two relays, a chain of frequency dividers feeds pulses at different repetition rates to counting circuits, a preselected number of one type of pulse being counted before pulses from a succeeding frequency divider are counted. Relay RLA operates, followed after the desired interval has elapsed by the operation of relay RLB. Pulses of repetition time 100, 10 and 1 m/s. are supplied from the frequency divider chain (not shown) to the grids of valves V1, V5 and V7. The first 100 m/s. pulse following the opening of switch S1 causes valve V1 to conduct and relay RL1 to operate and lock up, thus removing the short from valve V2. The next pulse causes valve V2 to conduct, relay RL2 operating to transfer charge from capacitor C1 to C2. This pulse also operates relay RL3 which locks up, thus allowing relay RLA to operate and commence the timing interval. Succeeding pulses operate relay RL2, the potential on the grid of valve V4 rising until the bias set by switch S2 is overcome, whereupon relay RL4 operates, locking up and removing the short on the grid of valve V5 to permit the 10 m/s. pulses to be effective. Relays RL5 and RL6 are operated by these pulses in a similar manner to the relays RL2 and RL4. When the desired number of 10 m/s. pulses have been counted, relay RL6 operates and locks up, commencing a timing period set by switch S4 which is calibrated in m/s. When a sufficient potential is available on the grid of valve V7, the next 1 m/s. pulse applied to the suppressor grid is effective to operate relay RL7 which locks up to permit relay RLB to operate and terminate the timing interval. The operation may be repeated by releasing the locked relays, closing switch S1 temporarily and discharging the capacitors by a relay operated by relay RLB. Relay RLB may cause a discharge lamp to operate to show the position of a mechanism set in movement by relay RLA.
