Title: Improvements in tacheometric telescopes
IPC: G01C3/30
Filed: 1931-04-13
Abstract: 361,249. Tacheometric telescopes. ZEISS, C. [Firm of], Carl-Zeiss-Strasse, Jena, Germany. April 13, 1931, No. 10767. Convention date, April 17, 1930. [Classes 97 (i) and 97 (ii).] A tacheometric telescope so constructed that part of the incident rays are deviated by a fixed amount at the objective so as to produce double images of a measuring staff, is provided with optical members in front of the telescope to cause the vertex of the parallactic angle to be displaced into the vertical axis of the telescope. The deviation of the rays may be produced either by splitting the objective or by mounting a deviating device in front of the objective ; in the latter case the deviating device itself can be constructed so as to produce the desired vertex displacement. Figs. 1 and 2 show an arrangement of the latter kind, the deviating device arranged in front of one-half of the objective c consisting of two wedges h<1>, h<2> separated by an air space. These wedges cause the rays striking the one half of the objective to be deviated relatively to the optical axis O-O by the parallactic angle alpha and also make the vertex of this angle lie at the point S at which the vertical axis X-X intersects the optical axis. The wedge system is mounted in a sleeve i which can be rotated to bring the wedges in front of either half of the objective. Where a split objective is employed the vertex displacement is effected by a parallel-sided plate mounted in front of one-half of the objective.

Title: A process of, and apparatus for, converting cellulose and the like into sugar
IPC: C13K1/02
Filed: 1928-04-13
Abstract: 315,462. Scholler, H. April 13, 1928. Drawings to Specification. Glucose. - Cellulose, cellulose dextrines, and the like or mixtures of cellulose and starch are converted into sugar by treatment under pressure with dilute acid, which is passed progressively through nearly exhausted, less exhausted and fresh raw material with removal of the sugar from the reaction chamber before decomposition thereof can occur, followed by cooling, neutralizing or reducing the pressure of the removed sugar to bring it to a stable condition. The sugar may be removed by percolation with an acidulated liquid. The interstices of the raw material may be reduced by compression or by filling the same with gaseous or solid substances or by recharging with fresh raw material in the course of the process. Fermented or unfermented liquor derived from the process may be used for the percolation of fresh raw material. Neutralizing substances may be added to the cellulose before the percolation, for complete or partial neutralization of the percolation liquid. The temperature may be allowed to fall in the direction of flow of the liquid. The residual acid may be extracted from the lignin by water under pressure. If required for alcoholic fermentation the alcoholic concentration may be increased by an acid percolation liquid containing alcohol, e.g. part of the fermented liquor, or fermented waste lye such as sulphite lye used in cellulose manufacture, and soluble nutrient solutions for the fermentation may be added before the percolation. In some cases the concentration of sugar may be increased by subsequent acid hydrolysis. Specifications 160,776 and 273,317 are referred to.

Title: Improvements in pressure measuring devices
IPC: G01L13/02
Filed: 1966-03-14
Abstract: 1,080,852. Measuring pressure electrically; pressure gauges. GENERAL ELECTRIC CO. March 14, 1966 [April 28, 1965], No.11061/66. Headings G1L and G1N. A pressure transducer of the force balance type includes an overpressure valve for preventing damage due to excessive pressures. The transducer comprises a housing having a partition 6 and two diaphragms 2, 3 defining chambers 4, 5. Pressures applied through conduits 11, 12 are transmitted by fluid in the chambers to a bellows 14, movement of which normally causes rotation of lever system 26 about pivot O, spring 38 normally preventing independent rotation of lever 35 about either pivot 36 or 37. Movement of lever 27 varies the inductance of winding 52, associated with fixed core 51 and armature 53, and so varies the amplitude of oscillation of oscillator 54. The output is rectified and applied via load 58 (meter, recorder or control device) to electromagnetic motor 43 to restore the system substantially to its null position. Overpressure in either sense causes lever 27 to contact stop 33 or 34, and lever 35 then pivots about 36 or 37, allowing bellows 14 sufficient movement for valve 21 to close conduit 16. The zero balance position is adjust by means of knob 65 which rotates spring 61 about pivot O. In parallel with motor 43 are a number of resistances R selected by switches S. The resistors are in binary relationship on to another and are selected singly or in groups to vary the percentage pressure span of the device. The span is defined as the ratio of the pressure difference to be measured to the difference between the maximum and minimum currents supplied to the motor over the measured pressure range.
