Abstract: 1425259 Educational appliances ISE ELECTRONICS CORP 31 Oct 1973 [8 Nov 1972 (3)] 50540/73 Heading G5G In teaching apparatus of the type wherein each of a plurality of students operates a selector to give answers to a common problem posed by a teacher, there is provided a recorder which prints out correct answers in one colour, e.g. black, and incorrect answers in another colour, e.g. red. As shown, a teaching apparatus comprises a teacher's station 1 including a plurality of switches 7a to 7e which are appropriately set for a particular problem to give " correct answer " signals; a plurality of student stations 5 each including switches 5a to 5e which the student sets to indicate his answer to the problem; a comparator 14 which sequentially compares the signals from each station 5 with the "correct answer " signals from the teacher's station 1 and produces different binary signals according to whether the student's answers are correct or not; and circuitry including a timer 17, an address circuit 13, a decoder 15 and a flip-flop (23) Fig. 2B (not shown), over which the binary signals from the comparator 14 are applied to the recorder (4) which is thereby controlled to print out, for each student, correct answer indications in one colour and incorrect answer indications in another colour. The apparatus may also include circuitry which controls the recorder to print-out the percentage of correct answers and which energizes an indicating lamp (31) when all the answers are correct.

Title: An improved oil firing system
IPC: F23C99/00
Filed: 1964-12-22
Abstract: 1,085,017. Oil firing system. COOROY BRICKWORKS PTY. Ltd., P. J. OLDS, and W. OLDS. Dec. 22, 1964 [Jan. 3, 1964], No. 51968/64. Heading F4T. [Also in Division F2] In an oil firing system the fuel oil is atomized by exhaust gases from an internal combustion engine. In the system described oil is drawn from a tank 10 through a filter 12 by a pump 13 driven by a belt drive 14 from a water-cooled internal combustion engine 15. The oil is then heated first in a jacket 17 of the engine and secondly in a heat exchanger 18 through which the engine exhaust gases pass. The I.C. engine has a modified cam-shaft so it can deliver its exhaust into the system under pressure. The fuel oil and exhaust gases then enter a diaphragm balance valve 24, Fig. 2 (not shown), through lines 19 and 20 respectively and connected to the line 20 is an adjustable gas relief valve 23. The pump 13 is arranged to deliver more oil to the valve than is needed by the burners and the excess oil is led away to preheat the oil in the tank 10 through line 41. The oil and gases are then led to the burners 43 through lines 39 and 40, the rates of flow being regulated by valves 45 and 46 before ejection from the orifices 47. In a modification where more than one I.C. engine is used the oil and gas leaving the engines are fed into concentric cylindrical manifolds 50 and 51, Fig. 3 (not shown) before being led away to the valve 24 by lines 19 and 20. In this modification any one of the engines may be cut out of the system without interrupting the system. Before firing, the oil may be heated to reduce its viscosity. With the valves 45 closed and valve 49 open the oil is allowed to continually circulate round the system until it has reached the required temperature. In a further modification, Fig. 4, the oil after being pumped through an engine jacket 68 is mixed with the exhaust gas from the engine in, a mixer 68 before being fed under pressure through a conduit 69 to a float balance valve 70, Fig. 5 (not shown). In the valve the oil-gas mixture separates out and the constituents leave via lines 84 and 85 to the burners. Excess oil used to preheat the oil in the tank leaves through line 82.

Abstract: Apparatus for treating webs of fibrous material, particularly paper, comprises at least one pair of spaced apart hollow elements defining a longitudinal duct, through which the web passes, each element having spaced apertures for the introduction and subsequent removal by suction of conditioning agents e.g. moist air, synthetic plastic materials paraffins or colours.  The duct 3 may be formed between successive pairs of elements 1, 2 and 1\sv, 2\sv &c., Fig. 1 (not shown), each element being subdivided into chambers 5, 5\sv and 6, Fig. 3 (not shown).  Conditioning agents fed to chambers 5 and 5\sv by pipes 9, 9\sv issue from transverse slots 7, 7\sv onto the web 4, and are subsequently removed from the web through transverse slots 8, 8\sv in the chamber 6, which chamber is connected by pipe 10 to a suction device.  The apparatus may alternately comprise one pair of hollow elements of appropriate length, each element having tubes communicating with the duct through transverse apertures.  The web is guided and transported through the duct by the conditioning agent streams issuing from the transverse apertures.

Abstract: 1,204,752. Electro-static copier. STROMBERG DATAGRAPHICS Inc. Nov.5, 1968 [Nov.6, 1967], No.52376/68. Heading G2H.  An electro-static copying machine has a continuously operating copy sheet conveyer 33, a roll 11 from which sheet material is fed in continuous form to the conveyer and sheet sensing means 76, 77 to activate a sheet cutting mechanism 23 to cut the sheet a predetermined distance from the leading edge thereof. Operation is possible in a small copy sheet mode, a large copy sheet mode or a continuous strip mode, the mode of operation being automatically determined by a code on a microfilm 46, to be copied, in the form of dots Fig.3 (not shown) the presence or absence of which is sensed by photo-electric devices (not shown). The conveyer 33 comprises perforated belts so that the copy sheet may be held upon the conveyer by suction means 42, 64 but the sheet may also slide along the belt during cutting when the sheet is momentarily stopped. In the single sheet modes the leading edge of the paper is sensed by one of the sensors 76, 77 to operate the cutting mechanism, the trailing edge is then detected by sensor 76 to operate a flash lamp 47 so as to expose the charged sheet with an image of the microfilm 46. The imaging means is adapted to automatically adjust the size of the image according to the mode of operation. The sheet moves on to a developing station 54 which is activiated by the leading edge of the sheet on passing a sensor 55. Toner is applied by a magnetic brush 56 from a container 57 replenished by means of a removeable toner disperser 58. In the continuous strip mode of operation the sensors 76, 77 are inactivated and the flash lamp timing is controlled by means of a timing wheel 127 which engages the surface of the copy sheet 13 and has a marker 130 so that on each rotation a sensor 131 supplies a pulse to the flash circuit.

Title: Gas-cooled nuclear reactors

Filed: 1967-11-30
Abstract: 1,255,928. Controlling reactors. BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd. 22 Nov., 1968 [30 Nov., 1967], No. 54658/67. Heading G6C. In a method of operating a gas-cooled nuclear reactor each of the control rods is arranged to control the temperature automatically in the neighbourhood of the rod. An individual control system for each control rod 5 comprises thermocouples. 7 which measure the temperature of the coolant at the outlets of certain of the neighbouring fuel channels 2, and the signals from which are fed into an averaging circuit 8. The average temperature is compared with the required temperature in a comparator 9 to provide a temperature error signal which is magnified and phase-advanced in an amplifier 11 to produce a control rod actuator signal. This signal is fed to a control rod actuator 12 which acts to adjust the position of the control rod 5 in order to reduce substantially to zero the temperature error signal obtained from the comparator 9. The transient temperature increase which normally occurs while fuel is being movedis is reduced by this means, and the power distribution across the reactor core is automatically trimmed to produce the optimum power distribution and hence maximum output from the reactor both during and after refuelling.
