Title: Improvements in flywheel compensated equipments for electric winding and other motors
IPC: H02M7/15
Filed: 1934-08-24
Abstract: 444,883. Electricity supply. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 24, 1934, No. 24434. Convention date, Aug. 26, 1933. [Class 38 (iv)] Equalizing load.-An electric motor 3 operated from grid-controlled rectifiers in associa. tion with a flywheel-converter 5, 6, 7, has a main rectifier 1 supplying it directly and an auxiliary rectifier 8 supplying the driving motor 6 of the flywheel-converter. The excitation and auxiliary circuits may be supplied from a further rectifier 9. The arrangement described is such that, assuming the flywheel set to be at full speed, movement of the controller arm 4 from the position shown excites the field of the generator 5 and the relay 15 ; the latter influences the means 13 adjusting the grid voltage of the rectifier 1 so that it supplies the current required by the motor 3. A relay 16 causes a contactor 17 to short circuit resistance 18 and increase the excitation of the generator 5 so that it participates in the current supply at a given rectifier current. A resistance with an auxiliary adjusting motor may be used in place of the elements 17, 18. A relay 14 causes the rectifier 8 to cease feeding the motor 6 of the flywheel-converter when a given system load is reached, so that energy is drawn drom the flywheel. Where the motor 3 operates as a braking generator it may supply energy to the flywheel. The machines 3 and 5 are permanently connected in parallel. The relay 14 may be placed on the D.C. side of the rectifier 8 or the relay 16 on the A.C. side of the rectifier 1. The adjusting means 11 may be mechanically coupled to the controller 4.

Title: Improvements in locks or fastenings for doors
Inventor: ROBERTSON ROBERT
IPC: E05B15/02
Filed: 1948-09-20
Abstract: 649,314. Latches. HALLAM, SLEIGH & CHESTON, Ltd. Sept. 20,1948, No. 24542. [Class 44] A vehicle door fastening comprises a pin 15, Fig. 1, mounted on the inner edge of the jamb which, on closing the door, rocks a fastening element 2 about its spindle 6, means being provided to retain the element 2 in its fastening position. The element 2 which is formed with a pair of arms 4, 5, on either side of the recess 3 in its upper edge, is fixed to the outer end of a short spindle 6, the inner end being rigid with a plate 8, Fig. 8. A spring 12 whose ends are anchored to a shallow case 13 and the plate 8, respectively, normally urges a shoulder 11 on the latter into contact with the upturned end 23 of a spring pressed slide bar 24. On the spindle 6 and plate 8 being rotated by the element 2 contacting pin 15, the end 23 slides over the edge of plate 8 to engage a second shoulder 9 on the plate, a further shoulder 10 affording a safety catch. To open the door from outside, a press button 27 located near handle 28 is actuated, whereupon a second spring pressed slide bar 30 is moved inwards by the contact of its upturned end 29 with the button plunger 34. Since the slide bars 24, 30, are coupled by a projection 31 on the downturned end of bar 24 engaging a recess 32 in bar 30, this movement of bar 30 releases the end 23 from shoulder 9, the plate 8 returning under spring action to the position shown. The plate 8 may be released from inside the door by rotating directly, or through a push button, an arm on a spindle 41. This rotates a bell crank lever mounted on the spindle so that one arm 36 of the lever retracts the slide 24 by acting on its upturned end 23. The outside push button may be rendered inoperative by bringing the arm 42 of a lever opposite the upturned end 43 of slide bar 30. A plate 17 to which the pin 15 is attached, is provided with a spring pressed slide 19, the upper surface 21 of which contacts the lower rounded corner 2a of element 2 on closing the door and finally engages beneath the element to prevent the door rattling or dropping. According to the Provisional Specification, the jamb is furnished with a C-shaped rib the upper portion of which replaces pin 15 and the lower portion of which contacts the base of element 2 if the door drops slightly, whilst the push button 27 is replaced by a trigger.

Title: Apparatus for determining the profile of a plane or cylindrical  surface
IPC: G01B11/24
Filed: 1972-05-26
Abstract: 1400841 Photo-electric profilometers FRANCE MINISTER FOR EQUIPMENT & HOUSING 26 May 1972 [28 May 1971] 24907/72 Heading G1A A profilometer comprises a light source arranged in such a way that as the beam scans the surface it is reflected to a point on the input element of a photo-multiplier device depending on the distance of the surface from a reference plane, the photo-multiplier device being arranged to scan the input element to produce successive signals representing the position of the incident light beam. As shown, Fig. 1, the light from a laser 1 is scanned across a surface R by means of a rotating prism 5. The surface is simultaneously scanned by rotating mirror 21 and the reflected beam is directed through an image correcting prism 37 which is rotated at half the speed of mirror 21, an interference filter 44 to reduce the effects of sunlight, and a lens 45, on to the photo-cathode 53 of a photo-multiplier device. The electrons emitted by the photo-cathode are deflected by coils 68 so that the position of the light beam can be determined by the deflection required for the electron beam to pass through an aperture into the multiplier section. A co-ordinate transformer 67 ganged to the mirror 21 provides an output which is compared with a 41 level generator 60 to provide a start pulse at 41 spaced positions across each scan. The output of a clock 56 is applied to divider 57 to produce 40KHz pulses which are differentiated (58) to produce 25Á S pulses which are applied to scanning circuit 24 to deflect the electron beam section of the photo-multiplier. The scanning circuit 24 is also provided with an input from analyzer 67 which is ganged to the mirror to correct for the change in optical path length as the mirror rotates. The pulses are also applied to a counter 63 which is stopped when an output signal is produced by the photo-multiplier the count being related to the position of incidence of the radiation on the target which itself depends upon the distance of the surface R from the axis of rotation of the mirror. The output of counter 63 is applied to a memory 64 and is gated (65) to a magnetic memory with continuous erasure. The apparatus is mounted on vehicle which moves along a roadway and is kept a constant distance from the edge by an optical system. A pendulum accelerometer is used to detect and correct for the angle of the laser relative to the transverse horizontal line. The optical axis of the apparatus is inclined at an angle to the longitudinal axis of the vehicle to compensate for the skew scan resulting from its forward motion. The apparatus may also be adapted for cylindrical surfaces by making the axes of the mirror and prism coincident and angling the mirror to receive the reflected radiation. The scan may be produced by a rotating laser instead of by the rotating prism 5.

Abstract: 707,881. Pivoted closures for aircraft. ROLLSROYCE, Ltd. Jan. 11, 1952 [Oct: 12, 1950], No. 24983/50. Class 4 [Also in Group XXV] A door for closing an aperture in the outer skin of an aircraft is pivoted about an axis so located that its orthogonal projection in the plane of the door passes through the centre of area of the door, and is spring loaded into an open position, the outer surface of the door or the outer skin of the aircraft in the region of the door, or both the outer surface of the door and the outer skin, being shaped so that when the aircraft is airborne the airflow in the region of the door creates a closing torque on the door opposing the spring load. The door comprises a sheet metal pressing 57 formed with a part aerofoil raised portion 57a and a forwardly extending lip 57b which abuts rubber pads 56 secured to the undersurface of the leading edge member 52 of the door frame so as to leave an air passage between the door and the frame. The door has depending side walls 58 fitted with bushes through which extends a hollow spindle 60 and the door also has a mass balance weight 61 carried thereon by brackets 62 riveted to the spindle and the door. The ends of the spindle 60 engage part spherical collars received in bearing blocks 64 riveted to the side members 50 of the door frame. The door frame members are. interconnected and riveted to the aircraft skin 51 the leading edge member 52 being extended rearwardly to overlap the flange 57b of the door and being provided with a shaped member 55 which completes the part-aerofoil section of the portion 57a. The trailing edge member 53 of the frame underlies the door at 53a with an air gap therebetween. When the aircraft is stationary the door is urged by springs (not shown) to the open position indicated by dotted lines and when airborne the door is closed by the suction created by the relative airflow over the part aerofoil section leading edge portion. The airflow through the gaps formed at the leading and trailing edges of the door reduce flutter. Alternative arrangements of part aerofoil sections and air gaps are described and an alternative hinge arrangement may be used comprising a small diameter spindle having low frictional resistance which deflects under load when the door is closed so that the hinge loads may be carried by a stiffer hollow spindle co-axial with the smaller spindle, (see Group XXV).
