Title: Improvements in or relating to derivatives of 2-hydroxy-diphenyl
IPC: C07C39/367
Filed: 1932-10-27
Abstract: 3-and-5-chloro-2-hydroxydiphenyls are obtained by chlorinating 2-hydroxdiphenyl by usual methods with or without catalysts and solvents.  Good yields are obtained when somewhat less than one mol. of chlorine is is employed.  The mixture of monochlor-compounds of close boiling points may be separated from unchlorinated and poly-chlorinated products by a preliminary distillation.  The 3-chlor- and 5-chlor-compound are then separated by fractional crystallization involving at one stage, conversion into alkali metals or alkaline earth salts.  A freezing-point / composition curve for the system 3 - chlor -2 - hydroxydiphenyl and 5 - clor - 2 hydroxydiphenyl, and a flow-sheet comprising a series of operations which may be employed to separate the compounds, are appended to the Specification.  The separation depends upon the fact that from compositions containing > 20 per cent of the 5-chloro-isomer, the amount of this isomer in excess of 20 per cent may be separated by fractional crystallization, while, when the composition contains < 20 per cent of the said isomer, a separation may be effected by conversion of the mixture into the salts referred to above, and fractional crystallization.  The crude chlorination product contains the 5-chloro-isomer to about 20 per cent of the mixed monochloro-compounds present.  The products are suitable as germicides, disinfectants, &c.

Title: Testing two-dimensional patterns
IPC: H01L21/66
Filed: 1975-07-18
Abstract: 1511919 Photo-electric apparatus for testing patterns PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 July 1975 [22 July 1974] 30213/75 Heading G1A [Also in Division H4] A method for testing a two dimensional pattern, e.g. a printed circuit, comprises synchronously scanning the test pattern 1 and a reference pattern 2 and comparing the signals produced so that a difference in the patterns causes an error indication signal wherein the reference pattern comprises at least three traces of different brightness values with respect to its pick-up, the two traces of extreme brightness values being narrower than the corresponding widths in the pattern to be tested and wherein error signals can only be generated at positions corresponding to the extreme brightness values. The term "brightness value" may refer not only to degrees of reflectivity but also to transmissivity and differential reflectivity or transmissivity to different wavelengths. The output from the reference pick-up is supplied to two threshold detectors (14, 15) Fig. 3 (not shown) which respectively provide a "1" output when the signal is below a first level or above a second level lower than the first. Grey levels produce a "1" on both outputs in which case logic circuitry (16) provides a "1" output whatever the value of the test signal. The output of the test pick-up is converted to a binary signal representing black or white and is input to the logic circuitry (16) such that when a black signal coincides with a white reference signal (or vice versa) a logical "0" or "error indication" is output. A display device (30) shows the test image and an error indication signal causes "bright up" or darkening of the faulty area. After two field scans of each test pattern, the first scan permitting alignment of the pattern with respect to the pick-up, a signal is delivered for example to the drive motor of the belt carrying the test patterns to move the next one into a position to be scanned. Means may be provided for marking faulty patterns or removing them from the belt. Alternatively a faulty pattern may be scanned until the operator is warned of the fault by lighting up of a lamp (34).

Patent GB-262450-A (GB)
Title: Improvements in brake mechanism for automotive vehicles
IPC: B60T13/46
Filed: 1926-04-12
Abstract: 262,450. Bragg, C. S., and Kliesrath, V. W. May 19, 1925, [Convention date]. Fluid - pressure. - Fluid-pressure brake mechanism, particularly for heavy motor vehicles and trailers, comprises reversing valve mechanism exterior to one or more double-acting cylinders which it controls and movable longitudinally with respect thereto, a connection which moves the valve casing with the brake mechanism, and an operator operated part connected with the valves and having a part movable with respect to the valve casing. The physical force of the operator can be applied to the brakes through the valve device. The valve mechanism comprises a casing 10 containing valves 40, 41 in a chamber connected to one end of the cylinders by a pipe 55 and valves 42, 43 in a chamber connected to the other end of the cylinders by a pipe 56. Movement of the valve-controlling sleeve 20, by a foot pedal connected to a lug 25, for application of the brakes opens valves 41, 43 to connect one end of the cylinders to suction through the pipe 55, apertures 24, the interior of the valve sleeve, and a pipe 62 connected to the intake manifold of the vehicle engine and to connect the other side of the cylinders to atmosphere through the pipe 56 and apertures 27, 29. Reverse movement of the sleeve 20 to release the brakes reverses these connections by opening valves 40, 42, a passage 19 providing communication from the atmosphere to the valve 40. The casing is connected by a lug 10<a> with one or other of the brake mechanisms for direct operation by physical force through the valve casing bv means of a collar 26 on the end of the sleeve 20, forming a lost-motion connection between the sleeve and the casing. The valve casing may be arranged so that the valves' 40, 42 are normally held open and one end of each of the cylinders is subject to suction and the other end to atmospheric pressure to retain the brakes in released position; or, as shown, the valves 41, 42 may be held open in released position so that both ends of each of the cylinders are subject to suction. In this latter arrangement, an adjustable stop 95 is provided for limiting the return movement of the valve casing, and an adjustable stop acting on the foot lever for arresting the valve-actuating sleeve. The valve casing may be connected to certain of the brake mechanisms by a lost-motion connection and be retracted by a spring against a stop, so that it does not ordinarily move with the brake mechanism, but the brakes may be operated directly by the physical force of the operator. The pipes 55, 56 are provided with flexible connections. The mechanism is described and shown as applied to a six-wheeled vehicle. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a brake mechanism in which the valve casing is connected by the lug 10<a> to a fixed part of the chassis in which the pipe 55 may be rigid. This subject-matter does not appear in the Specification as accepted.
