Filed: 1959-01-27
Abstract: 869,967. Hydraulic apparatus. YOUNG, D. H. Jan. 27, 1959, No. 2910/59. Addition to 840,216. Class 69 (2). The fluid-pressure engine described in the parent Specification and comprising an engine piston reciprocated in one direction by fluid pressure and controlled, on the pressure stroke, by hydraulic damping fluid forced through a variable-setting valve into a reservoir has a container for liquid connected with the engine cylinder and subjected to steam pressure for providing the said fluid pressure for operating the engine piston. The container for the liquid (such as water) may be formed with cooling fins and is provided in its top wall with a valve-controlled steam inlet and in its bottom wall with a valve-controlled fluid-inlet conduit leading to the inlet of the cylinder. The fluid pressure is supplied through the valvecontrolled inlet to the engine cylinder so as to move the piston and thereby displace the hydraulic damping fluid on the other side of the piston through a passage controlled by the variable-setting valve to a reservoir surrounding a pump cylinder, the piston of which is on the same rod as the engine piston. The engine piston at each end of its stroke, is arranged automatically to control a valve thereby exhausting the pressure fluid from the engine cylinder. A full description of this arrangement is to be found in the parent Specification.

Abstract: 607,347. Transformers. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., JENNINGS, R. E., and ELLIS, R. F. Jan. 31, 1946, No. 3097. [Class 38 (ii)] The circulating current between adjacent taps in a tap-changing transformer is limited by employing a contact brush of carbon or other high resistance material suitable to carry the load and wide enough to bridge the gap between adjacent contacts. As shown, tapped transformer winding section B is connected to switch S of the usual type having successively moving contacts W1 and W2, but not necessarily of the "on-load" type; section A is in two parts A1 and A2 connected to the "on-load " type tapping switch S2. The moving contact W3 of this switch is a carbon or like high resistance brush. The total voltage across winding section A is substantially equal to that between two adjacent tappings on section B. The switches are geared together so that one revolution of switch S2 causes switch S1 to move only through a single step.

Class 97(1) Apparatus for determining the thickness and/or absorption of an object comprises a diffraction grating 5 illuminated by a lamp and condenser arrangement, an objective 6 which images the grating on a screen 10, means for locating the object in the rear focal plane of the objective 5 or in a plane conjugate thereto so that a phase difference is introduced between light passing through the object and light by-passing the object to give contrast in the grating image on screen 10, and means for evaluating the image contrast. As shown, there may be disposed in the rear focal plane of the objective 5 three containers 8, the central one containing a solution under test and the other two the solvent, compensators 7 in the form of relatively adjustable wedges being disposed in front of the outer containers 8. In use, the wedges are adjusted to multiply the contrast in the grating image, the setting of the wedges then giving a measure of the optical thickness and for absorption of the solution in the central container 8. Instead of using compensators 7, a measure of the image contrast can be obtained photo-metrically as by using a mask covering bright striations in one area of the image and dark striations in another area and comparing the voltages generated by photo-cells receiving light from the respective image areas.
