Patent GB-724531-A (GB)
Title: Compressor and drive
IPC: F04D25/02
Filed: 1952-05-29
Abstract: 724,531.. Variable ratio gearing. GARRETT CORPORATION. May 29, 1952 [June 14, 1951], No. 13654/52. Class 80 (2) [Also in Group XXVI]. A compressor rotor 11 is driven at a relatively constant speed from an engine driven shaft 19 connected to a compressor driving shaft 18 by a two-ratio gear 22 in series with a continuously variable epicyclic gear 23. The gear 22, Fig. 3, comprises two gear wheels 24, 27 which mesh with gear wheels 25, 28 on an intermediate shaft 26 and which are respectively connectible with the shaft 19 by means of a one-way clutch 44 or a hydraulically actuated clutch 47 the one-way clutch overrunning when the clutch 47 is engaged. The shaft 26 drives the carrier 89 of planet wheels 88 which mesh with a ring gear 91 and a sun gear 103 on a shaft 99 splined to the compressor shaft 18. Rotation of the reaction ring 91 is retarded by an oil pump 108 connected thereto by a gear train 98, 105, 106. The output of the pump 108 is throttled by a valve 117 which is actuated against a spring 126 by a diaphragm 123 closing a pressure space 125. When a higher rotational speed of the compressor shaft 18 is required the fluid pressure admitted to the space 125 is increased by means such as described in Specification 715,290. Such pressure increase causes closing movement of the valve 117 resulting in producing greater resistance to rotation of the ring gear 91 with corresponding increase of speed of shaft 18. A drive is taken from the gear wheel 28 to a pump which supplies oil under pressure to actuate the clutch 47 and lubricate the gears: Oil is admitted to the operating space 58 of the clutch, via a hollow portion of the shaft 19, a port 61 and a passage 62, at low shaft speed. At a certain shaft speed centrifugal force moves a valve member 66 outwardly against spring action to close the port 61. Bleed holes 64 allow oil to escape from the space 58 and the clutch 47 disengages. The shaft 26 is then driven through the low ratio gear train 27, 28.

Abstract: 1,152,442. Irradiating bodies. ALDERSON RESEARCH LABORATORIES Inc. 29 April 1966, No. 13726/66. Heading H5R. Radiation dose distributions required for the treatment of malignant tumours are determined by using a plurality of adjustable clamps and marking styluses to enable a patient to be positioned invariantly on a table in a treatment position, making radiographs through a radiography frame containing objects to mark a co-ordinate grid system on the radiographs to permit the tumour &c. to be located precisely within the co-ordinate system, drawing patient contours on charts marked with a corresponding co-ordinate system and transferring the locations of the tumour &c. (as determined from the grid system) on to the patient contour chart. A plaster cast of the patient in the treatment position is then made and transferred to a fixture incorporating a sliced phantom containing a human skeleton and plastics materials with the same radiationinteraction properties as human soft tissues and lungs. Mouldable material is then inserted between the cast and phantom to build up the phantom to match the contours of the patient and the matched phantom is placed on the table. A test treatment is then administered to the phantom and the dose distribution in the phantom is measured for use, after modification if necessary, in the treatment of the actual patient. The patient is returned to the treatment position for the radiation treatment. The treatment table (see Fig. 1) comprises the clamps marking styluses 37 to enable invariant location of the patient on the table, a radiography frame 23 containing spheres and pellets to mark the grids on the radiographs contouring mechanism 22. There is also a means (see Fig. 8, not shown) for registering the plaster cast of the patient with the fixture and sliced phantom for use during matching the phantom to the patient contours.

Title: Improvements in or relating to methods of and apparatus for forming sheet glass
IPC: C03B13/04
Filed: 1926-05-31
Abstract: 259,150. Jackson, L. Mellersh-, (Hartford-Empire Co.). May 31, 1926. Rolling.-A rolling-aparatus for forming plate glass has a casting-table with a surface which is convex in cross-section in order to facilitate the spreading of the mass of glass in front of the roller. The table may be made to tilt about a transverse axis to accelerate the spreading of the glass. The table 10 is pivoted on a base 11 and is provided with marginal ribs 12 for supporting the roller 13 and for determining the thickness of the glass plate. The surface of the roller is concave to the convexity of the table 10. When a mass of glass 18 is deposited on the table, the convexity of the table causes the glass to spread out more rapidly in front of the roller. A fluid-pressure cylinder 14 enables the table to be tilted backwards or forwards as desired, either to cause the glass to flow back against the roller or to spread out more rapidly along the table. When the plate has been formed, it is moved into the leer across a table section 30. The surface of this section is convex at the end adjoining the table 10, but becomes flat towards the leer. The plastic plate is flattened by its own weight when passing over the plane section of the table.

Abstract: 830,034. Television. FERNSEH G.m.b.H. May 7, 1956 [May 6, 1955], No. 14051/56. Class 40 (3). In television transmitting apparatus a video signal a is applied via cathode followers 2 and 11 to an output terminal 21 and has its black level controlled by means of a gated rectifier circuit 4, 6, 7, the D.C. potential from which is added to the television signal at the grid of cathode follower 11 by way of a further cathode follower 14. The rectifier circuit, which is rendered operative only during the picture interval by gating wave b, has a fast attack time of approximately 0.001 seconds, as determined by time constant C6, R8 and a slow release time of 0.5 seconds as determined by time constant C6, R7. The coupling circuit R13, C12 for the D.C. potential has a time constant of 0.2 seconds. The combination of a fast input response with an overall response which is long in relation to the duration of a picture causes the circuit to be substantially less effective in the case of picture signals representing relatively small dark points than in the case of signals representing a relatively large dark area. A diode 5 clamps the less positive parts of gating wave b to earth potential. The signal of the output of cathode follower 11 is re-blanked by valve 18 which receives a blanking wave c at its grid. The amplitude of the blanking level is limited to a value set by diode 20 and bias network 22, 23.
