The invention comprises compounds of the formula (where R 1  is OH, OR 3  or halogen, R 3  is a C 1-5  alkyl group and R 7  is a C 2-4  halogenated alkoxy group having two fluorine atoms on the α- carbon and at least one H on the #-carbon). Compounds in which R 1  is OR 3  can be obtained by heating a compound of formula or by esterifying a compound of the first formula (where R 1  is OH or halogen) with R 3 OH. The quinoline-3-carboxylates (where R 1  is OH) can be obtained by heating the esters with dilute NaOH and adding the mixture to mineral acid in an alcohol, e.g. HCl in methanol. The acid chloride is obtained by treating the acid with thionyl chloride at 80‹ C. Alkyl α - carbalkoxy - #[3 - R 7  - anilino] acrylates of formula V are obtained by reacting a 3-R 7 -aniline with a di-(C 1-5  alkyl) (C 1-5  alkoxy) methylene malonate. 3-(C 2-4  halogerated-alkoxy) anilines are obtained by treating m-aminophenol with a C 2-4  α,α-difluoro-halogenated 1-alkene.

Title: Circuit for producing intermittent illumination of a lamp
IPC: H05B39/04
Filed: 1970-12-05
Abstract: 1367457 Visible signalling apparatus CAV Ltd 19 Nov 1971 [5 Dec 1970] 57872/70 Heading G4F [Also in Division H3] An electric circuit produces intermittent illumination of a lamp by the repeated charging and discharging of a capacitor C. The lamp 13 lights when switch 14 is closed and hence capacitor C charges until it biases transistor TR1 on. When this occurs, the coil 15 of a relay is energized with the result that relay contacts A and B close. The closure of contacts A maintains conduction of transistor TR1 until capacitor C is completely discharged, the latter being caused by closure of the contacts B which also connects lamp 13 directly across the supply 9 to give full illumination. Diode D1 prevents damage to the transistor when the flux in coil 15 collapses. More than one transistor may be used.

Abstract: 1324039 Valves EATON YALE & TOWNE Inc 15 Dec 1970 [2 March 1970] 59509/70 Heading F2V In a pilot operated valve having an inlet 11 leading to, and an outlet 12 leading from an annular chamber 17, the valve member is comprised by a diaphragm member 15 which is reinforced by, and has extending therethrough a relatively harder grommet structure 23, the diaphragm being co-operable with a seat 20. The structure has a vent passage 29 extending therethrough, and has its lowermost portion 39 formed of a plurality of fins (39 bb, Fig. 2, not shown) which are a relatively close fit within the outlet passage bore 34 and which remain within at least a portion of the bore in all states of the diaphragm valve. A grommet portion, (39a, Fig. 4, not shown), intermediate the portion 39 and the diaphragm is formed as a relatively loose fit within the outlet bore, this intermediate portion being located within the outlet bore 34 only when the diaphragm valve is at or close to its seat 20. In operation, fluid entering the annular chamber passes to a biasing chamber 32 via diaphragm passages and grommet passages 33, 35, 36. the fluid within the latter chamber serving to retain the diaphragm valve in its seated condition as long as the vent passage 29 is closed by a solenoid operable pilot valve member 26, 27. The sizing and nature of the grommet end and intermediate portions relative to the outlet bore is said to prevent the occurrence of water hammer.

Title: Radio compass and means for controlling its motor
Inventor: SALMET GASTON RAOUL
IPC: G01S3/42
Filed: 1968-12-19
Abstract: 1,260,670. Radio direction-finders. G. R. SALMET. 19 Dec., 1968 [2 Jan., 1968], No. 60387/68. Heading H4D. Relates to a radio compass in which two crossed loop aerials are rotatable together about their common vertical axis by a motor which is controlled by a voltage derived from a comparison of the outputs of the aerials. In one embodiment, Fig. 1, motor M is of the kind which reverses on a change in the direction of current through its armature. Identical and orthogonal loops C 1 , C 2  are connected sequentially to an R.F. transformer by a square-wave from oscillator A acting on diodes 1a, 1b and 2a, 2b. A conventional radio receiver B is connected to an amplifier and impedance-matching circuit C to a phase-sensitive detector D also fed with an output from oscillator A to thereby produce the difference between the peak voltages, such difference representing the difference between the outputs of the loops. The difference voltage is sent via an impedance matching circuit E and a D.C. amplifier F to one terminal of motor M the other terminal of which is connected to a fixed voltage v, where 2v and zero are the extreme magnitudes of the difference voltage. The motor thereby brings one of the planes bisecting the loops into the direction of the transmitter. Associated scales are described, Fig. 2 (not shown). Ambiguity may be resolved by an auxiliary compass or, in the embodiment, by switching in an aerial 17: if it is connected when the motor system has reached equilibrium that system rotates in a direction depending on the direction of the transmitter. In a detailed circuit arrangement, Fig. 3, oscillator A is a transistorized multivibrator switching at, e.g., 50 to 100 Hz and incorporating a network 23 to increase the durations of the leading and lagging edges of the output waveforms; amplifier C incorporates an input filter to remove the higher audio frequencies when the transmission is amplitude-modulated, an emitter-follower transistor circuit 25 for impedance matching and amplifying stages 27, 28 having D.C. feedback to stabilize and set the gain and a diode 29 for temperature correction; detector D comprises diode arms 33a, 33b, the phase of the reference voltage input being made symmetrical about voltage v by a transistor 35; impedance matching circuit E consists of an emitter-follower transistor circuit and a diode 42 providing compensation for base-emitter voltage drop and for temperature changes; D.C. amplifier F similarly includes compensation and current flows through motor M in a direction determined by whether transistor 49A or 49B is conductive: at equilibrium (i.e., the transmission bisects the angle between the loops) the voltage at input 45 is v, neither transistor 46A, 46B can conduct, and the motor does not rotate. A braking current is generated by the circuit F to avoid overshoot. In a modification a permanent sensing facility is provided, Figs. 4, 5 (neither shown). (For Figure see next page.)

Title: Load responsive brake control valves
IPC: B60T8/18
Filed: 1979-05-25
Abstract: A load responsive brake pressure regulator for a motor vehicle braking system comprises a rocking beam (29), whose fulcrum position depends on the loading of the vehicle axle (15) and which controls hydraulic fluid supply from a brake master cylinder (12) through a ball valve (43, 44) to the brakes of the vehicle. Brake pressure acts on the beam (29) through piston (46) in opposition to master cylinder pressure acting through piston (35) and through piston (39). Above a certain value of master cylinder pressure, only a proportion of master cylinder pressure is applied to the (as shown) right hand end of the beam. This pressure is reduced either by a proportioning valve (61) (Figure 2) or by means of an auxiliary piston (39) (Figure 1), which at a predetermined pressure overcomes a pre-loaded spring 40 to oppose the piston (35). <IMAGE>
