Title: Television system with permanent copy printer
IPC: G03G15/047
Filed: 1966-05-06
Abstract: 1,114,081. Pictorial communication system. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 6 May, 1966 [7 May, 1965], No. 20134/66. Heading H4F. [Also in Division G2] In a pictorial communication system an image 18 viewed by a camera tube 12 subsequent to operation of a shutter 16 is scanned off in a single frame only and communicated to a receiving station 37 which incorporates a storage type display tube 25 and an electrostatic image printing system 36. The arrangement permits an adequate optical exposure time to be provided for making a plurality of copies of a transmitted image without occupying the transmission channel 24 for the whole of the exposure time. The image produced by tube 25 is normally available for direct visual observation via an aperture 39 but may be projected via lens 55 to the electrostatic printer by manual operation of a lever 48 to move a deflector 47 into the light path. The electrostatic printer incorporates a cutter 70 for severing a recording sheet from a roll 57, a charging means 72, a printing station 52 where the sheet is secured by a vacuum system 69, a toner apparatus for developing the charged image visually, a fuser and developer apparatus 74 and a receptacle 76 where the final recording is deposited. The operation proceeds wholly automatically under the control of circuit, Fig. 4 (not shown), subsequent to actuation of lever 48. The passage of the recording material through the printer is sensed by switches 52-56. The exposure is timed by a timer motor. The image produced by tube 25 is blanked (by interrupting the high voltage supply to the display screen) except when the severed recording sheet is located in the printing station 52. The control circuit incorporates an adjustable counter so that it may be caused to repeat the recording operation a predetermined number of times and thereby produce a corresponding number of copies of the transmitted image. A second embodiment is described with reference to Fig. 5 (not shown), in which the image produced by tube 25 may be monitored during the recording process. For this purpose the optical path from the tube includes a partly transparent deflector (120) by means of which a proportion (80%) of the image light is directed to the printing station (52) whilst the remainder passes to television camera tube (130) connected to a remote display cathode-ray tube (134). A shutter (127) is included in the light path to the printing station for blocking the image during movement by the recording sheet. In this embodiment the control circuit, Figs. 6-8 (not shown), is based on a motor-driven cam system. Reference is made (without giving details) to the use of two storage display tubes to permit reception of a second image whilst a first is still being recorded.

Title: Combined variable resistor and electric switch
IPC: H01C10/36
Filed: 1957-06-26
Abstract: 849,926. Cam-operated switches. CHICAGO TELEPHONE SUPPLY CORPORATION. June 26, 1957 [July 30, 1956], No. 20194/57. Class 38 (5). [Also in Group XXXVI] In a combined variable resistance and switch, the operating shaft 7 carries a contact assembly 15 which coacts with an arcuate resistance element 11 and a collector ring 13, both of which are mounted on the base 8. The desired contact pressure at the resistance element and collector ring is maintained by an earthing plate 21 which overlies the base 8 and which has a U- shaped notch engaging in a groove 23 in the shaft. The shaft 7 also drives, by means of a non-circular extension 31, the switch-operating cam 32 which is journalled in the wall 40 of the switch base 9 and which is formed with a pair of axially-spaced lobes 74. In the switch " open " position each lobe 74 abuts an ear 73 on a moving contact spring 47 and holds it away from a fixed contact 46. Clockwise rotation of the cam causes the ears 73 to pass over humps 75 on the lobes 74 and the contacts to close with a snap-action. Anti-clockwise rotation of the cam to open the contacts causes an initial wiping movement of the contacts thereby promoting self-cleaning. The moving and fixed contacts are formed with terminals 68, 69 and 57, 58 respectively which pass through slots 67, 64 and 56, 51 respectively in the switch base. Each moving contact is held against the side of the switch base by a locating boss 65 and each fixed contact is held between locating bosses 52, 53. The variable resistor is enclosed in a metal cover 25 having tags which are clenched over the switch base 9 to hold the switch and resistor units together. Another tag 34 on the cover 25 provides an earthing connection. In another form, Figs. 7-9 (not shown), the metal cover 25 is omitted and the switch and resistor are enclosed in a single insulating housing.

Title: Apparatus for bagging carrots
IPC: B65B25/04
Filed: 1974-05-08
Abstract: 1473575 Packaging machines; shoots FILPER CORP 8 May 1974 [7 June 1973] 20372/74 Headings B8C and B8S [Also in Division G1] Apparatus for bagging carrots or like objects comprises means for feeding carrots to an accumulation station and means, e.g. a weigh hopper 15, Fig. 1, at the station which receives carrots from the feeding means and which, when it has received a group of a predetermined weight discharges the carrots into an open-topped bag located therebelow. As described carrots 2 are fed on an endless conveyer 1, Fig. 1, and removed laterally therefrom by flexible vanes 5 of a rotary device 4. The carrots fall down an incline 7, Fig. 19, and are picked up by the flights 8 of a conveyer 9, there being in general one carrot on each flight. From the top of the conveyer 9 the carrots fall into an upwardly directed pocket of the weigh hopper 15, which is supported rotatably in arms 18 pivoted at 14. When a predetermined weight of carrots is present in the hopper the arms 18 rock to lower the hopper and release a peg thereon from a stop 26 so that the hopper rotates to deposit the weighed carrots into a shoot 31. When the arms 18 tip they break a pneumatic circuit which causes the conveyer 9 to stop while the hopper 15 is emptying. The carrots are re-aligned vertically in the shoot 31 before falling into an opentopped bag 69, which is supported by clamping jaws 106, 107, Fig. 3, at the end of one arm of a rotatable turret 56. Discharge of the carrots from the hopper is prevented if no bag is positioned below the shoot 31. As the turret 56 is rotated step-wise the filled bag is first carried over a vibrated support 154, Fig. 25, to a sizing station, where a slidable blade 165 removes portions of carrot which extend above it, and then to a station where the bag neck is gathered and tied, the bag then being removed from the turret arm. The emptied arm next passes to a station where it receives an opened bag, and then to the filling station. Open topped bags 69, Fig. 14, are supported on a wicket 81 and tubes 65 and the leading bag is opened pneumatically by air from a tube 78. A blower 79 keeps the bag open, and an arm 175 on the turret arm helps to open the bag mechanically.  The shoot 31, Fig. 25, has a wall 44 which is spring-loaded to the position shown, but which is moved about a pivot 47 to the position shown in phantom by a turret arm engaging a projection 48 to release any carrots jammed in the shoot.

Filed: 1973-04-30
Abstract: 1429995 Controlling by ultrasonic waves MULLARD Ltd 30 April 1973 20374/73 Heading G4F In an ultrasonic, e.g. 40 kHz, remote control system utilizing the transmission of an adjustable number of short tone bursts followed by a relatively long tone burst, all the tone bursts are on the same frequency and all the short tone bursts are of equal duration. The invention is particularly applied to the control of a television receiver or a quadraphonic system. The short tone bursts are 5 ms. long to afford a compromise between a sufficiently fast information rate and obturation by echoes. Transmitter, Fig. 3.-5 ms. pulses from generator MC feed into transmitter TM, Tx and into a decode counter DC1. When a decoder DD1 gives an output on the terminal to which selector S is set a monostable MO1 emits a 20 ms. pulse the leading edge of which inhibits generator MC to produce the long pulse DP and resets counter DC1. In practice selector S is a number of switches to effect the requisite functions, e.g. channel selection, volume control, &c. It is arranged that battery power is switched on only when the remote control is to be effected. Receiver, Figs. 4, 4a.-In one embodiment wherein G1 ... G4 are NAND gates and MO 2, 3 are monostables, waveform B is produced and fed to a decimal counter DC2 the output from which, in binary coded decimal form, is transferred to a memory MEM1 by waveform E. Decoder DD2 is utilized to operate the associated control function. At the end of a transmission a low output at G resets the memory and, via gate G2, the counter. In a modification NOR gates are utilized and a level detector (a Schmitt trigger) is incorporated. Figs. 5, 5a (neither shown); in that modification random outputs are not selected when working close to the range limit of the system and incorrect outputs are not momentarily selected at the beginning of a transmission (e.g. due to obturation of the acoustic beam). In a further modification operation is effective only after the correct number of short bursts have been received twice in succession, Figs. 6, 6a (neither shown).

The tubulent stream is removed from the pyrolysis zone and the solids separated from the volatilized fuel values and carrier gas. The separated solids may be degasified and desulphurized by heating to 1260‹ to 1530‹ C. for up to about 20 minutes in a gas substantially free of free oxygen. A portion of the separated solids is heated to 540‹ to 870‹ C. and utilized to form a portion of the turbulent stream to be recycled through the pyrolysis zone. The coal may contain sulphur and the inert carrier gas contains hydrogen or coal containing sulphur and 1 to 5% by weight of a particulate sulphur acceptor, e.g. iron oxide, based upon the total weight of sulphur in the coal, may be introduced into the pyrolysis zone, e.g. mixed with the coal prior to forming the turbulent stream. The portion of the separated solids which is not recycled through the pyrolysis zone is heated in a degasification zone at 650‹ to 985‹ C. in the presence of a carrier gas substantially free of free oxygen to form a hydrogen-rich gas stream and a degasified char; the hydrogen-rich gas stream may be used as the inert carrier gas and the degasified char may be heated to 1260‹ to 1530‹ C. in a gas substantially free of free oxygen. The volatile fuel values may be catalytically hydro-treated with at least a portion of the hydrogen-rich stream.
