Title: Process for the preparation of derivatives of quinoline 3-carboxylates
Inventor: BOWIE RAYMOND ALEXANDER
IPC: C07D215/56
Filed: 1966-04-20
Abstract: Quinoline derivatives of the formula <FORM:1122435/C2/1> where R1 represents a C12-C14- alkyl group or an aralkyl group optionally substituted by halogen or alkyl or nitro radicals, R2 represents an alkyl group and the benzene moiety of the quinoline nucleus may be substituted by halogen or alkyl, alkenyl or alkoxy groups, are prepared by reacting an anil of the formula <FORM:1122435/C2/2> where the benzene nucleus may be optionally substituted as above, with a phosphorus oxyhalide followed, if necessary, by hydrolysis of the 4-halogeno-quinoline when formed.  If approximately equimolar amounts of the anil and the phosphorus oxychloride are used, the reaction yields the 4-hydroxy-quinoline derivative. An excess of phosphorus oxyhalide yields the 4-halogeno derivative which may be hydrolysed under acidic or basic conditions, e.g. using an acetic acid/sodium acetate mixture, The cyclisation reaction is preferably effected by heating the reactants in an inert diluent, e.g. toluene.

Title: Traffic signalling system
IPC: G08G1/097
Filed: 1978-08-31
Abstract: A traffic signalling system comprises local units for control of the signals (Sg1-Sg14) at road junctions. These can be selectively controlled by local signal plan generators (Spg) or by a central signal plan generator. The aim of this system is to ensure that switch-over to the local signal plan generator does not occur on each occasion the central signal plan generator is disturbed, but only in the exceptional cases in which this is actually necessary. Thus the invention provides that, with the aid of a fault counter (Z) each consecutive faulty control of the local intersection units by the central signal plan generator is recorded and that the aforementioned switch-over does not occur until a given counter setting has been reached. <IMAGE>

Title: Hysteresis switching circuit
IPC: H03K5/08
Filed: 1978-10-30
Abstract: A circuit arrangement for monolithic integrated circuit threshold switch having particular, but not exclusive, application in providing a switching current for an integrated injection logic circuit. In order to avoid the problems of a threshold switch being operated by spurious pulses, the switching range of the threshold circuit is automatically adapted for the supply voltage by adjusting the turn-on voltage so that it is always a fixed voltage difference or interval below the supply voltage irrespective of the variations in the operating voltage. In a typical embodiment, Figure 2, the threshold switch comprises two amplifying transistors (T7, T8) connected in series, a constant current circuit connected to a first current mirror circuit (T1, T2) and via a first diode (D1) to a second current mirror circuit (T3, T4 and T5) which supplies current to the collectors of the two amplifying transistors (T7, T8). The base of a first (T7) of the amplifying transistors is connected to an output of the first current mirror which is connected to an input (E), and, via a second diode (D2), to a second (T8) of the amplifying transistors. The first and second diodes (D1 and D2) determine the lower and upper switching thresholds, respectively. <IMAGE>

Patent GB-2011764-A (GB)
Title: Synchronizing circuit for a digital arrangement
IPC: G11C19/28
Filed: 1978-12-21
Abstract: Arrangement for synchronizing digital operating cycles with an external clock signal. The arrangement comprises a calculating unit 5, and a circulating store 6 which produces a sequence of multi-bit coefficients in a predetermined order in each cycle. The store 6 comprises switching means for circulating the coefficients in the store either all coefficients being circulated in series, or each individual coefficient being internally circulated in a particular sub- port of the store 6 in series. A counter 21 produces a coefficient clock signal HM, and a counter 22 forms operating cycles synchronous with the word clock signal HM and starts each operating cycle at each characteristic transition of an external clock signal HE appearing after the end of each cycle. The signal HE is reproduced from incoming data by a clock recovery circuit 2. The switching means in the store 6 are controlled by the counter 22 so that the sequence of coefficients circulate in series once in each cycle, the individual coefficients circulating internally for the remaining period of time in the cycle. <IMAGE>
