Title: Precession instrument for use in the photography of the reciprocal lattice of a crystal
IPC: G01N23/205
Filed: 1963-10-18
Abstract: 1,003,116. Epicyclic gearing. M. J. BUERGER. Oct. 18, 1963, No. 41199/63. Heading F2Q. [Also in Division H5] A precession instrument, for use in the photography of the reciprocal lattice of a crystal, comprises a planar surface 28 upon which a photographic plate may be supported in a plane parallel to the plane of the reciprocal lattice being photographed, the surface being rotatably supported from a structure 20, wherein the rotational movement of the plane is a rolling motion about an imaginary cone along a generator of the cone such that the generator migrates at a constant angular rate and a rotation of the plane about its normal at a constant rate but in the direction opposite to that in which it is rolled, the rates being so related that each point of the plane makes contact with a particular point on the imaginary cone on each cycle. With the cone having a half opening angle of 90 degrees Á and the generator migrating at a constant angular rate w, the plane is rotated at a constant rate (1 - sin Á)w. As shown, a motor 24 drives a body 26 about an axis 21, the body 26 supporting the planar surface 28 so that a normal 27 to the plane is at an angle to the axis 21. The plane 28 is rotated about its normal upon rotation of the body 26 about its axis by a gear-wheel 29 coupling to a fixed gear 25 concentric with the axis 21 through an idler gear 30. In alternative arrangements, the gear assembly is replaced by an endless belt and pulleys, or two synchronous motors are used, one to drive the axis 21 and the other to drive the axis 27. The photographic plate holder 28 may be linked by universal joints and arms to the crystal holder, Fig. 10 (not shown). In a further embodiment, Fig. 9, two similar supporting structures 72, 73 are provided for the crystal and photographic plate respectively. The photographic plate is mounted upon a holder 94 in a mount 87 which can pivot on supports 88 and be locked in any orientation by a screw 92. The annular element 79 is rotatably supported in a holder 75, and the processional movement of the plane 94 is obtained by gear links 85-84, 81-80, 76-95, 95-96 and 96-90. The crystal holder 72 is of the same construction, the crystal 102 being supported in the processing plan in front of a layer line screen 104 having an annular aperture 105.

Title: Drawbar assembly
IPC: B62D53/02
Filed: 1970-08-27
Abstract: 1,274,574. Drawbar. DEERE & CO. 27 Aug., 1970 [29 Aug., 1969], No. 41307/70. Heading A1P. A drawbar assembly 12 for attaching a single-axle semi-trailer to a tractor enables the draw-hook 62 to be equally visible to the driver in its raised and lowered positions since the lower position of the hook is rearward of the upper position. The assembly comprises a draw bar 42, having the draw-hook 62 at one end, which is pivoted on an axle 50 which also carries links 52, 54. The forward end of the draw bar is pivoted on an axle 60 which also carries the rods 34, 36 of rams 22, 24 which operate the draw bar. The rams are double-acting, interconnected and operated by valve 74.  The locking pin 90 may be operated hydraulically (Fig. 5). A line 98, leading from port 80 of ram 24, connects with a chamber to the left of the head 92 of the pin 90. The left chamber is connected to the right by channels 102, 104, cross-flow being hindered by a sprung check-ball 106. When raising the draw bar the pressure in line 98 is not normally sufficient to overcome spring 108 but when the draw bar hook 62 contacts the stop 66 the pressure increases so that the chcek ball is displaced and the pin 90 moves to the right, due to the difference in areas of the two faces of head 92. To disengage the pin, line 98 is exhausted so that ball 106 is seated and ball 114 is displaced. The pin may be actuated instead by a manually operated mechanical linkage, by pneumatic means or by electromagnetic means. The arrangement of the draw bar is such that the pulling forces of the tractor are cushioned in the rams; opening.88 is elongate to give the pin 90 lost motion for this reason.

Title: Acceleration control for gas turbine engines
Inventor: YOUNG JOHN MICHAEL CRISPIN
IPC: F02C9/32
Filed: 1960-12-08
Abstract: 1,006,598. Gas turbine engines. JOSEPH LUCAS (INDUSTRIES) Ltd. Dec. 8, 1961 [Dec. 8, 1960], No. 42236/60. Heading F1G. [Also in Division G3] The invention relates to an acceleration control for a gas turbine engine. In the embodiment shown fuel is supplied from a tank 11 to the burners 12 by means of a pump 10 the fuel supply being controlled by means of a valve 9. The valve 9 is connected by a link 8 to the stem 3 of a piston member 2 disposed within a cylinder 1 so as to afford two chambers 4 and 5. A control rod 16 formed with a recess 17 is disposed within the hollow stem 3 and controls communication between the chambers 4, 5 through an orifice 6 in the stem. The piston is acted on by a spring 7 which tends to move the piston downwardly. The chamber 4 communicates with the pump outlet while the chamber 5 communicates through a device 13 with the pump inlet. The device 13 returns to the inlet side of the pump an amount of fuel dependent on engine speed, and comprises a rotary member 14 having a diametrical bore in which is disposed a shuttle 15. When the bore registers with the chamber 5 the shuttle is moved to the left hand end of the bore and the remainder of the bore is filled with fuel. When the member 14 has rotated through 180 degrees, the shuttle is again moved to the left and the fuel within the bore is delivered to the inlet side of the pump. At steady speed the flow of fuel from the chamber 4 to the chamber 5 is just sufficient to balance the flow of fuel through the device 13 and the valve 9 is then disposed in the partlyopen position shown. When it is desired to accelerate the engine, the control rod 16 is moved outwardly to cut off communication between the chambers 4 and 5. The device 13 continues to transfer fuel from the chamber 5 so the pressure in that chamber commences to fall and the piston 2 is moved upwardly by the pressure in the chamber 4. The valve 9 is thereby actuated so as to increase the fuel flow to the burners 12. In this way too-rapid acceleration is prevented and risk of stalling is minimised. When it is required to decelerate, the control rod 16 is moved downwardly to increase the flow of fuel between the chambers, the pressures in the chambers therefore tending to equalise whereupon the spring 7 acts to move the valve 9 so as to decrease fuel flow to the engine.

Abstract: 1,133,290. Silo bottom unloaders. J. OBERBERGER. 18 Sept., 1967, No. 42443/67. Headings B8E and B8S. Pusher members 2 are mounted in guide apertures 3 in the wall 1 of a silo and can be extended into the interior to support the contents above the bottom discharge mechanism during its operation. The pushers as described are stepped and the means described to extend them include a screw and nut device driven from a motor through bevel gears, a motor driven rack and pinion device and a piston and cylinder device. The discharge mechanism comprises a sweep arm cutting device in the form of a worm 21a, or a cylinder provided with cutting knives, supported on a toothed ring 6 and rotated by gearing driven by a motor 7 while a motor 8 drives the cutting device. In use the sweep arm cuts the contents and conveys it outwards assisted in the case of a cutting cylinder by a blower so that it drops below a base-plate 4 into a space in which arms 18, with conveyer blades and cover-plates 19, attached to a toothed ring 16 are rotated by a motor 17 to sweep the material into a discharge pipe 12. Each cover plate is stopped over the discharge pipe 12 while a blower 11 is switched on to discharge the material through a flap 15 after which the blower is switched off and rotation of the arms 18 re-started. The blower 11 may be used to ventilate the silo by opening a ventilation flap 13. When the sweep arm has completed a revolution in the silo a space exists above it and a plate 9 is rotated by a motor 10 over the arm to protect it while the pushers 2 are retracted to allow the contents to fall to fill this space after which the plate 9 is retracted and a fresh discharge cycle started.
