Patent GB-688211-A (GB)
Title: The manufacture of derivatives of amino acids
Filed: 1949-07-22
Abstract: The invention comprises N - benzyl - paraaminosalicyclic acids in which the benzyl group may be substituted by one or two halogens, obtainable by the action of benzaldehyde or its mono- or di-halogen derivatives on p-aminosalicylic acid and either simultaneously or subsequently, reducing the product in presence of a hydrogenation catalyst.  In examples, benzaldehyde reacts with paraaminosalicyclic acid in acetic acid/ethyl alcohol, and the mixture is reduced with hydrogen with palladium/charcoal to give the 4-benzylaminosalicylic acid; 4-chlorobenzaldehyde and 2 : 4-dichlorobenazldehyde give corresponding products.  The intermediately-produced para-N-benzylidene compounds may be isolated.

Filed: 1945-08-01
Abstract: 596,733. Electrification detectors; electrostatic meters. ELLIOTT BROS. (LONDON), Ltd., and PETCH, H. S. Aug. 1, 1945, No. 19799. [Class 37] A " live " potential indicator comprises two electrodes, so disposed in relation to a chamber containing two immiscible fluids of differing permittivities that a P.D. between the electrodes causes a visible change in the distribution of the fluids within the chamber. As shown, a cylindrical chamber 2 within a disc electrode 1 and closed by a window 3 contains air and a high permittivity liquid, e.g. petroleum hydrocarbon in equal proportions, whereby the electrostatic effect of a P.D. between the disc 1 and a second electrode 4 of pencil form with its point at the centre of the window 3 distends the level of the liquid, as shown in Fig. 2. For H.T. use the indicator may be permanently affixed to a bus-bar or mounted in a portable test device, Figs. 3 and 4 (not shown), there being sufficient capacity between the second electrode 4 and earth to a produce a characteristic movement of the liquid which is preferably coloured to facilitate observation. In a modification, Fig. 7 (not shown), for bus-bar attachment, a metal rod electrode extends centrally into a chamber formed within an insulating disc and filled with liquid and air. This chamber is closed by an inner and outer window to form a second chamber filled with a liquid conductor, e.g. waterglass which acts as the second electrode. According to the Provisional Specification, the indicator of Fig. 1 may be modified by the inclusion of further pointed electrodes 4 to accentuate the indication and may be further modified by including a reservoir into which the activated liquid drips to be fed back into the chamber.

Title: Vehicle anti-skid braking system
Inventor: MORTIMER FRANK RADCLIFFE
IPC: B60T8/52
Filed: 1964-05-13
Abstract: 1,100,044. Fluid pressure control of brakes; disc brake. DUNLOP CO. Ltd. 4 May, 1965 [13 May, 1964; 11 Jan., 1965], Nos. 19832/64 and 1097/65. Headings F2E and F2F. A vehicle anti-skid system including an hydraulically operated friction member engageable with rotatable member and capable of limited movement about the axis thereof includes a means for controlling the pressure of fluid in the brake-applying mechanism, the control means comprising a fluid pressure operatad thrust device mounted adjacent the friction member and supplied with fluid at the pressure existing in the applying mechanism to generate a thrust to oppose the drag force exerted on the friction member, and a valve controlling the supply of fluid to the said mechanism and operated by the thrust device to interrupt or reduce the supply of fluid when the thrust exceeds the drag force. In the disc brake shown the caliper housing 4 containing opposed hydraulic cylinders and friction pads has small freedom to move about the axis of the disc 2 against spring restraint, the movement being limited by pins 11 in slots 13. The control means comprises a cylinder 14 with a piston 15 abutting the housing. Fluid pressure supplied to a chamber 19 from a master cylinder passes valve 22, held open by the piston, to enter chamber 20 and act on the piston 15, conduit 8 directing the fluid to the brake cylinders 5. The thrust of the piston 15 balances the frictional drag tending to move the housing 4 towards the cylinder 14, the drag being proportional to the fluid pressure and the piston thrust until the tyre 3 begins to slide relatively to the ground, when the drag reduces and the piston 15 and housing 4 move rightwards closing valve 22, the movement of the piston increasing the volume of chamber 20 to lower the braking pressure. In another embodiment (Figs. 2 and 3, not shown) a second piston (51) encircling the valve is provided between the chambers of the thrust member. When the valve closes this piston is moved towards the housing to bring one arm of an associated bell-crank lever (53) into contact with a cam surface formed on the edge of the disc, the piston then being oscillated thereby to pump the brakes. The oscillation is stated to also cause an oscillation of pressure in the master cylinder and to vibrate the brakeoperating lever to warn the driver that too much braking pressure has been applied.

Abstract: 716,687. Testing materials by ultrasonic vibrations. KRAUTKRAMER, J., and KRAUTKRAMER, H. Aug. 11, 1952, No. 20208/52. Class 118 (2). Relates to ultrasonic pulse-echo systems for detecting flaws in thin sheets of materials of the type in which an electro-acoustic transceiver transducer is coupled to a surface of the sheet by a wedge such that a beam of shear waves is propagated through the sheet by multiple reflections between the two surfaces of the sheet, the echoes produced by reflected waves travelling back over a similar path being displayed on a cathode-ray oscilloscope. In such systems a reference echo from a boundary may not be produced and since such an echo is useful for testing the coupling efficiency between the transducer and the sheet, for detecting the absorption or scattering effect of flaws incapable of producing echo indications and for estimating the size of flaws which do, a reference echo is produced according to the present invention by employing two spaced transceiver transducers connected in parallel and mounted on opposed wedges c and e so that the cathoderay display comprises a response p representing the pulses transmitted simultaneously by each transducer, a response t representing the signal received by each transducer from the other after at least one reflection at a surface, a response r representing the echo received by each transducer due to reflection at the other wedge and reponses s and q representing the echoes produced by a flaw b as received by the left and right-hand transducers respectively. When testing a pipe, the two transducers are adjacent and the two wedges are arranged to transmit waves travelling in opposite directions round the pipe, Fig. 2 (not shown).
