Abstract: 1,266,734. Grading examination sheets; remedial teaching. AUTOMATA CORP. 15 Dec., 1969 [16 Dec., 1968], No. 61104/69. Headings G4M and G5G. Multiple choice answer positions on a sheet are notionally divided into sets, e.g. corresponding to tests taken on different occasions, the answer positions on the sheet are sensed and a particular set of answers is compared with a corresponding set of stored correct answers, e.g. on a concurrently sensed master sheet, the number of correct and incorrect answers in the set being printed on the sheet in an area corresponding to the particular set of positions. Different sets of answers may thus be checked on successive passes of the answer sheet through the sensing station using a different master sheet on each pass. The answer sheet may be re-used, e.g. to enter answers to different tests on different occasions, the scores for each test being separately accumulated and printed on the sheet. In either of the above methods of use, a mark is made adjacent any incorrectly answered question position and at the correct answer choice position, as described in Specification 1,210,265. The answer sheets may also be used for remedial teaching. In this method of use, the score obtained by a student in a test is printed in a selected position on the sheet, but although incorrectly answered questions are indicated, no mark is made at the correct choice position. The sheet is returned to the student to make a second attempt at the incorrectly answered questions, the original answers being erased. On a second pass through the machine, the score is printed in a different selected position on the sheet, and the questions which are still incorrectly answered are distinguished by marks in a different colour or position to the original error-indicating marks.

Abstract: 1289762 Cathode ray tube display systems BUNKER-RAMO CORP 21 Jan 1970 [14 Feb 1969] 2967/70 Heading H4T An arrangement for CRT display of alphanumeric information includes a visible " cursor " displaying the position at which a further character may be entered from a keyboard, the position of such cursor being marked in storage by a binary 1 in the otherwise unused intercharacter space between the video character representations. As described the character is represented by binary data controlling the unblanking of the beam in a 7 x 5 dot matrix x produced by a vertical stroke raster, and a sixth (inter-character) stroke (always blanked) carries a 1 in position 6 out of 8 (each eighth position representing vertical spot flyback) to mark the cursor for the next character. Two tracks 20, 21 on a magnetic storage drum carry the video information which is read at 23, 24 into FF1, FF2 for sampling by pulses B1, B2 to control the display unit. If a binary 1 is read in stroke 6 FF4 is set by AND gate 35, and remains set until stroke 6 of the next character. Provided counter 37 (which receives one pulse per drum revolution, i.e. one pulse per full display cycle) is enabling gate 36 then an unblank signal is passed to 10 for each spot position of the next character, but the counter causes a blinking unblanking which does not mask the visual display of any character stored there. Such character (e.g. N, A) may instruct the nature (numeric, alpha-) of information to be keyed in, which keyed character then replaces the instructing character. Such keying-in also advances the cursor marking to the next character position (Fig. 4, not shown). Specification 1,289,761, which relates to validation of characters entered at a cursor position in similar apparatus, is referred to.

Abstract: 1290750 Indicating failure of braking system BENDIX CORP 18 Aug 1970 [2 Sept 1969] 39648/70 Heading F2E [Also in Division H1] A differential pressure switch for indicating failure in one of the two halves of a split braking system, comprises two pistons 32, 34 loose in a bore 14 with a switch actuating cam 37 between them. Each piston 32, 34 carries a stop 74 which in the central position shown rests against a retainer 64, 65 urged by a spring 62, 63 against the end of the bore 14. When the brakes are applied the pressures in the two halves of the system are applied at ports 18 to the ends of the pistons. If the applied pressures are equal the assembly of pistons 32, 34 and cam 37 remains fixed. If one pressure is smaller the whole assembly is driven to the right or left, a button 40 of a switch riding up a slope 38 on to a flat 39 on the cam to close the switch and energize a warning lamp 44. When the brakes are released the trailing piston is returned to the position shown by the spring acting through the respective retainer and stop 74. The leading piston however, -having no restoring force, remains where it is, as does the cam 37 and therefore the switch remains closed. If, when the brakes are operated again, the failure has been overcome, the pressure returns the second piston and the cam to the central position.

The arrangement is such that in the straight ahead position of the steering wheel circuits are completed through both solenoids via a finger 28 so that no articulation is possible but when the wheel is turned, say to the left, the circuit to solenoid 22 is broken and valve 17 allows fluid to flow back to the reservoir and hence articulation of the vehicle may take place. If a jack-knifing condition is then sensed by the driver the wheel is moved to the right to correct this and valve 17 is closed, thus preventing any further articulation. An over-ride switch may be incorporated and used during reversing and slow running. The finger 28 may alternatively be mounted on the track rod of the tractor.

Abstract: A system of the present invention uses small swing differential source synchronous voltage and timing reference (SSVTR and /SSVTR) signals to compare single-ended signals of the same slew rate generated at the same time from the same integrated circuit for high frequency signaling. The SSVTR and /SSVTR signals toggle every time the valid signals are driven by the transmitting integrated circuit. Each signal receiver includes two comparators, one for comparing the signal against SSVTR and the other for comparing the signal against /SSVTR. A present signal binary value determines which comparator is coupled to the receiver output, optionally by using XOR logic with SSVTR and /SSVTR. The coupled comparator in the receiver detects whether change in signal binary value occurred or not until SSVTR and /SSVTR have changed their binary value. The same comparator is coupled if the signal transitions. The comparator is decoupled if no transition occurs. When the flight time between a master device and a slave device is greater than the cycle time of the system clock, the system uses multiple clocks. One clock controls transmitting signals from the slave devices to the master device, and another clock controls initiating each slave device to communicate signals to the master device. A first clock may be looped back to the slave devices to communicate signals such as requests from the master device to the slave device.
