[Classes 75 (ii), 75 (iii), 75 (iv), and 126.] Mounting reflectors on lamp casings; lamps, supporting ; electric lamp lanterns; lantern screens.-The trace of a reflecting surface on a plane cutting it in one direction is a portion of a conic, and the trace on every plane at rightangles to the first-mentioned plane and passing through the focus of the conic is a parabola whose focus coincides with the first-mentioned focus. In one form, the trace on the first plane is also parabolic. In the embodiment shown in the Figure, the surface of a barrel-shaped vessel 10, of glass or similar material, is formed by the rotation of a parabola 1 about the chord 2 which passes through its focus O. As shown, the chord 2 is perpendicular to its axis 3, but if required may be at any other angle. Half the surface, viz. that lying between the lines 11, is silvered. The barrel is mounted between two aluminium or other metal endplates 12, 13 packed with felt 14 and connected together by straps which are detachable from the end 13. Pins 17 and a screw 18 secure the barrel to the end 12. A bracket 26, mounted on lugs 27, carries a lamp holder 25. The end 12 has a gland entry 15 for cables. Spill shields 16 are mounted on the other end 13. A sheet metal cover 24 is attached to the ends 12, 13. The lamp is mounted on the fork 21 by means of trunnion screws passing through an opposite pair of the straps joining the ends 12, 13, and is held in position by a pinch screw. The reflector may be made by silvering the whole of the surface of the barrel and dividing it into two or more portions. It may be of thin metal or other opaque material, made reflecting and divided up as before. Reflectors shaped as set forth may be used in heating apparatus. Reference has been directed by the Comptroller to Specifications 7345/07, [Class 75, Lamps &c.], 226,838, and 282,674, [both in Class 75 (ii), Lamp chimneys &c.].

Abstract: 396,486. Sheet-folding machines. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Crafts, C. S. ; 645, South Lombard Avenue, Oak Park, Illinois, U.S.A.) March 17, 1932, No. 7984. Convention date, March 19, 1931. [Class 100 (i).] In machines for folding paper or like sheets comprising a blade 11 on one cylinder 10 which tucks the sheets between gripper-jaws 30, 31 on an adjacent cylinder 12, the blade 11 is arranged so that it is parallel to the jaws at its point of exit and so that its tip travels at the same speed as the outer edge of the folding jaws. Prying action of the blade 11 on the jaws 30, 31 and possibility of displacement of the sheets is thus prevented. The two cylinders 10, 12 are coupled together by interengaging gearwheels 35, 36, Fig. 2, the radius of the pitch circle A, Fig. 3, of the gear 35 being slightly less than the radius to the outer edge of the jaws 30, 31, and the radius to the point of the blade 11 being slightly more than the radius of the pitch circle B of the gear 36 so as to obtain the required speed relation between the blade 11 and jaws 30, 31. The blade 11 is arranged non-radially to its cylinder 10 so that as it leaves the jaws 30, 31, at the position 5e it is substantially parallel to the faces of the jaws. A recess 15 is provided in the cylinder 10 to accommodate a blade-holding block 20 which can be adjusted by screws 24. A strip 21 bolted to the block 20 engages a rib 19 on the blade 11 so as to hold the blade in position, and a spring 23 allows the blade to yield slightly.

Abstract: 1,113,704. Valves. ELLIOTT MACHINE TOOLS Ltd. 11 Jan., 1967 [25 Feb., 1966], No. 8427/66. Heading F2V. [Also in Division B3] A machine tool, such as a surface grinding machine, comprises a work-table and a tool head which is relatively movable in at least one direction by fluid pressure actuated means and by manually operated feed means, the fluid pressure actuated means being continuously operable to apply pressure to take up backlash during operation of the manually operated feed means. As described the machine tool is a surface grinding machine having a saddle 1 movable by a piston-and-cylinder device 2, 3 controlled by a reversing valve 8 supplied with fluid from a control valve 7 and pump 6, the control valve being movable from the position shown, in which supply and delivering ports 11, 12 are interconnected, anticlockwise 90 degrees to a position interconnecting the supply port 11 with an exhaust port 13. The control valve has a member 9 formed with a groove 14, Fig. 2, which communicates with the supply port 11, and a pair of recesses 16, 17 selectively registerable with the delivery and exhaust ports 12, 13 upon rotation of the member. The valve member is mounted on a spindle 18 which at its upper end is pinned to a dog 19 in slotted connection 21 with a rotary cam 22 which effects engagement and disengagement of the hand feed mechanism. The lower end of the spindle has a tongue 28 to which a head 26 is pivotably connected, the head being spring urged to engage a pin 24 with a recess in the valve member. In operation, a handle 31 on head 26 is provided for rotating the valve member so as to connect the supply port 11 selectively to the delivery and exhaust ports. When hand feed is used, the hydraulic force acting on the saddle is normally relieved but for accurate operation can be maintained. The valve member is disconnectible from the spindle 18 by rocking head 26 so as to disengage the pin 26 from the recess in the valve member which is then turnable by a handle 32 to connect the supply port to the delivery port while the hand mechanism is operated, the hydraulic pressure acting with or against the hand mechanism to eliminate backlash in the mechanism.
