Title: Improvements in or relating to means for supporting crank shaft bearings
IPC: F16C9/02
Filed: 1945-05-11
Abstract: 591,521. Mounting crankshaft bearings. BUGATTI, E. May 11. 1945, No. 11841. Convention date, July 16, 1943. [Class 12 (i)] To facilitate the assembly of a crankshaft by its being moved axially into the crankcase so that the bearings already assembled on the shaft come into line with the receiving bores 2 in the transverse web plates 20 of the crankcase, these bores are machined over not more than 180 degrees to form the bedding surface 2a while the remainder of the bore 2b is large enough to provide side play so that the axial assembling movement can be effected slightly off centre without touching the machined 180 degrees arc of the bore. Thereafter removable section pieces 11 slid between guide checks 12, 13 in the web plates 20 are bolted up against abutment shoulders 15, 16 whereby a machined arc on each section piece beds against the bearings oppositely to the 180 degrees machined are 2a. The machining of the arc on the removable section pieces 11 is effected previously with thin foil or paper inserts below the abutments 15, 16 but on subsequent assembly the inserts are omitted and thus the bearings are bedded under pressure when the oblique tie rods 17, 18 for the removable section pieces 11 are tightened up. The bearings on the crankshaft comprise. half brasses 7, 8 lined with anti-friction metal and located by studs 10 in the two half bearings 3, 4 which are bolted together to provide a bearing body of circular form and of greater extent than the crank webs of the shaft. Undulating spring segments 28 fitted into co-operating grooves in the bearing and in the mounting bores prevent axial movement after assembly; the segments are compressed radially by the insertion of the section piece 11.

Abstract: 1327191 Pulse radar TELEFUNKEN PATENTVERWERTUNGS GmbH 28 March 1962 [18 April 1961] 11981/62 Heading H4D In a Doppler radar system, for the detection of low-flying targets, multipath ground reflection interference is reduced, thereby reducing the locating error of the system, by the use of narrow band, pass speed gates and narrow band filters. Target angular position is derived from the sidebands formed by the aerial scanning modulation of the echo signals if the aerial is not pointing directly at the target and the sidebands lie outside the speed gate bandwidth. In one embodiment (Fig. 4) the Doppler frequency is passed directly to a narrow band filter 42, while the sidebands are fed to modulating means comprising two mixers 44, 45 and a scanning frequency generator 27 which feeds the scanning frequency in quadrature to the two mixers 44, 45. The latter supply two narrow band filters 46, 47 each centred on frequency # 0  to filter out target information represented by the amplitude of an # 0  term. The filters supply phase detectors 48, 49 which eliminate the field strength parameter and control the antenna servo. In another embodiment (Fig. 7) the outputs from the mixers are combined, after one is phase-shifted by #/2, and supplied to a single narrow band filter 46.

Title: Improvements relating to the testing of electrical apparatus
IPC: G01R27/18
Filed: 1937-04-27
Abstract: 494,345. Indicating faults ; measuring resistances. NORTH METROPOLITAN ELECTRIC POWER SUPPLY CO., and SHOTTER, G. F. April 27, 1937, No. 12059, [Class 37] Pressure tests of insulation are effected by applying a potential through a resistor in parallel with a gaseous discharge device, a condenser being alternatively switched in parallel in place of the resistor. With resistor 1, Fig. 1, in parallel to the discharge tube 4, and the load at 5 subject therefore to the continuous supply from transformer 7, the tube 4 should not glow if the insulation is sound. With the condenser 3 in circuit instead of the resistor 1, the rate of flashing of the tube 4 will be a measure of insulation resistance. Resistor 10 limits the short-circuit current, and the apparatus can thus be employed in continuity tests. In another arrangement, Fig. 2, the discharge tube is in parallel with a variable resistor 11 and the amount of resistance required to light the tube 4 is a measure of the resistance under test, the resistor 11 being calibrated in megohms. A fixed resistor 12 may be connected in series with resistor 11, and a variable shunt resistor 13 is provided for use if the glow is too faint. Resistor 13 can also be calibrated in megohms and a single reading in respect of resistors 11, 13 obtained.
