Title: Digital synchronizing system
IPC: H04N5/08
Filed: 1974-10-10
Abstract: 1474816 Television RCA CORPORATION 10 Oct 1974 [18 Oct 1973] 43928/74 Heading H4F To render the vertical deflection system of a television receiver immune to triggering by spurious signals the supply of triggering signals to the vertical deflection system is prevented except during a "search-interval" during which true vertical synch pulses are expected to occur. As shown in Fig. 1 (which is concerned with a system using a horizontal scan rate of 15.75 kHz and a vertical scan rate of 60 Hz) horizontal frequency pulses derived from horizontal oscillator 27 are supplied via frequency doubler 46 to a divide-by-525 counter 80 which produces an output at D at each 525 count and produces an output at E at each count of 520 and an output at F at each count of 5. The 525 count output resets the counter via OR gate 60, the 520 count output sets a bi-stable multivibrator 100 to place a logical "1" at its output G and the 5 count output resets the bi-stable by placing a logical "0" at output G. The period during which the multivibrator is set constitutes the "search-interval" and during this period AND gate 95 is conditioned to pass vertical synch signals in the composite synch output of synch separator 26 to synchronize the vertical deflection circuit 41, such synch signals also acting via OR gate 60 to reset counter 80 which is thus reset by either such synch pulse or by the counter output at count 525. The "search-interval" may be made shorter or longer. In the event that noise pulses occur (at terminal A) between the vertical synch pulses, counter 80 may be reset so that AND gate 95 will not be conditioned when, eventually, a vertical synch pulse occurs, to pass such pulse to trigger the vertical deflection circuit 41. In this condition internal vertical synch system 50 responds to the fall in the vertical sawtooth voltage below a threshold value to produce a trigger pulse for circuit 41 (Fig. 3, not shown). In a second arrangement the output, at full count, of a further divide-by-525 counter supplied with the frequency-doubled pulses from terminal J is supplied via an OR gate (having the B input to circuit 41 as a second input) to its own reset input and also as a trigger input to circuit 41 (Fig. 4, not shown). The organization of counter 80 is described with reference to Fig. 2, not shown.

Title: Melamine-formaldehyde resins for electrodeposition
Inventor: TAWN ALEC RICHARD HARNSEY
IPC: C09D5/44
Filed: 1965-10-11
Abstract: Polar melamine-formaldehyde resins are prepared by the transesterification of a highly etherified melamine formaldehyde condensate by means of a hydroxy carboxylic acid which does not contain an ether linkage.  The initial condensate may be a polymethoxymethyl melamine, in which the degree of substitution is not less than five and in which at least 80% of the methylol groups are etherified.  The hydroxy acid may be aliphatic or cycloaliphatic and contain one, two or three carboxyl groups and one or two primary or secondary hydroxyl groups.  Aromatic acids may be used but are less reactive.  Acids used in the examples include dimethylol propionic acid, 12-hydroxy stearic acid, lactic acid, 2-hydroxybutyric acid and m-hydroxy benzoic acid.  The proportions of condensate and hydroxy acid may correspond to one melamine nucleus per hydroxyl group of the hydroxy acid.  The trans-etherified product may be partially or completely neutralized by a volatile base (e.g. triethylamine) and diluted with water.  The resins are suitable for use in electrodeposition processes and may be readily mixed with other resins, e.g. alkyds and other polyesters, to form coating compositions.

Abstract: 1487943 Error correction in memories WESTERN ELECTRIC CO Inc 24 Oct 1974 [29 Oct 1973] 46138/74 Heading G4A In a memory error correction system including a memory 10 (Fig. 1) having p rows and n+m columns supplying an n-bit output word at terminals 0-16 from one of its rows, if a check circuit 11 detects an error in the word, the bit position of this error is determined in error control circuit 17 and the correct bit is inserted into one of the m columns in the appropriate row and subsequently substituted in the place of the faulty bit. In the embodiment of Fig. 1 when a parity error is detected in a word read out from a matrix memory the bit in error is found by for example writing first all "1's" and then all "0's" into the memory. If the error is in column 1 the binary number 1 is stored in register 16 and flip-flop 15 is set. The output of the register 16 controls (1) a multiplexer 14 so that the input signal on line 1 is directed in inverted form to a spare column (column 17) of the memory, (2) a decoder 13 which with a low signal applied at input EN1 applies the low signal on output 1 to gate 1M1 and (3) a decoder 12 which supplies on an output lead 1 the signal from column 17 which is inverted by NAND gate 1C1 so that it has the value of the original signal applied on input lead 1. In a further embodiment the matrix has a plurality of spare columns (17-19, Fig. 2, not shown) each associated with a four bit register (306-326). A steering circuit (38) directs the position number of a bit in error from error control circuit (37) to one of the registers, each register having a pair of decoders as in the embodiment of Fig. 1, one of which is used to inhibit a gate (3M) and the other of which is used to supply the output from the associated column to another gate (3C).
