Title: Improvements relating to filing cabinets
IPC: A47B63/06
Filed: 1935-02-20
Abstract: 438,926. Filing-cabinets. REMINGTON RAND, Inc., 465, Washington Street, Buffalo, New York, U.S.A. Feb. 20, 1935, No. 5523. Convention date, Feb. 20, 1934. [Class 146 (i)] [See also Group XVII] In a filing-cabinet a number of trays are arranged closely behind each other and can be withdrawn endwise through an opening in the wall of the cabinet, which is provided with guides to engage the trays at or near their inner ends so that a withdrawn tray is maintained in engagement with the cabinet, but may be slid along the wall and turned so as to lie against the cabinet. The trays 44, Fig. 4, which may be of the normal visible-index type, for instance, that described in Specification 101,682, [Class 146 (i)], are housed in forwardly tilted slides 39, formed as open-topped U- shaped members and resting with the bottom 40 of each engaging the side flanges 41, Fig. 5, of the previous slide and closing its open top. The slides lie between shoulders 37 formed on the sides of the cabinet and a removable bottom 6, and are laterally positioned by shoulders 35, 36, 11, 62. The bottom 6 is flanged to engage a circumferential groove and flange 8 on the cabinet, and is provided with rollers 14 and castors 15. The side flanges of the slides are folded over to a box-like shape and accommodate on one side a box-shaped unit 63 which houses mechanism for latching the trays in position. A latch 75 is pivoted to the unit 63 and is controlled by a spring 73 connected at its other end to a slide 70 provided with a projection 71. The projection 71 is engaged by a pin 50 on the tray 44 so that, as the tray is pushed home into the slide, it is cushioned by the spring 73 and is retained by the latch 75 engaging a slot 79 in its side. The tray may be released by depressing a button 38 which actuates a member 85 in the unit 63 so as to cam back the latch 75. The tray is then partially projected by the spring 73. The pins 50, when the tray is fully withdrawn, engage under flanges 19 on the top of the cabinet, and the tray may be run along on rollers 51 mounted on the pins 50 until it can be laid flat for inspection on the top of the other trays, which are bevelled off at the top so as to present a smooth surface. The cabinet is provided with a cover 94, which when open is housed in a slide 57, but can be drawn outward and forward to cover the trays 44 and push-buttons 38, and then locked in position by a lock 18. The cover 94 is provided with cushions 97 to engage the flanges 19, with a slidable handle 100, and with a transverse bar 103 which engages under flanges in the slide 57 and acts to guide the cover and also engages under a projection at the end of the slide when it is locked in position. A cushion 110 for the cover is provided at the lower end of the slide. A compartment 30 for index cards rests upon flanges 27 at the rear of the cabinet and contains a smaller divided tray 33 for clips, signals, &c. covered by a pivoted lid 28. A fingerhole and index-holder are provided at the forward end of each tray.

Title: Improvements in or relating to highly active wide-band absorbers for short radio waves
IPC: H01Q17/00
Filed: 1956-02-22
Abstract: 814,310. Radio wave absorbers. GENEST GESELLSCHAFT FUR ISOLIERUNGEN, W. Feb. 22, 1956 [Feb. 23, 1955], No. 5567/56. Class 40 (7). A wide-band radio wave absorber for preventing reflection by a wall comprises a plurality of electric or magnetic dipoles arranged in front of, at or in the surface of the wall, each dipole being associated with two resonant systems one of which is damped. Each magnetic dipole may comprise a conductive loop or a slot in a conductive surface. When the dipoles are resonant, e.g. #/2 conductors or slots, each dipole constitutes one resonant system and the other is provided by (1) spacing the dipoles from the wall, the space between the dipoles and the wall being preferably filled with lossy or loss-free dielectric or insulating material, Figs. 1-4, and Fig. 11 (not shown); or (2) coupling each dipole to a resonant circuit, Figs. 9 and 10 (not shown). When the dipoles are non-resonant, e.g. short linear conductors or small loop elements, each dipole is coupled to a resonant circuit and the other resonant system is provided by (1) spacing the dipoles from the wall, Figs. 7 (not shown), and Fig. 8; or (2) coupling each dipole to two interconnected resonant circuits. When the dipoles are spaced from the wall the spacing is (2n + 1)#/4 for electric dipoles and n#/2 for magnetic dipoles. Electric dipoles may be formed of conductive or lossy strips, e.g. conductive lacquer, graphite paper, colloidal graphite or impedance foil, applied to the solid filling the space between the dipoles and the wall; loss-free dipoles should be connected to a dissipative load, e.g. a graphite wedge, or damped resonant system, located behind the wall, Fig. 6 (not shown). When loop elements are employed, each loop element 15, Fig. 8, is arranged perpendicularly to the wall and may be formed of metal wire or graphite paper coupled to a resonant system 9 behind the wall 1 by a coaxial line 5. The resonant system 9 may comprise (1) lossy dielectric layers spaced from a conductive termination of the line 5, (2) grooves in the metallic or lossy inner and outer conductors of the line, or (3) a layer of iron powder in the coaxial line 5 and loss-free dielectric. When slot elements are employed the elements may be made lossy by filling the slots with lossy material or by forming the slots in an impedance foil; the associated resonant circuit may comprise a cavity resonator coupled to the slot by a waveguide. When resonant #/2 elements are employed they are spaced parallel to each other with a separation less than #/2 but non-resonant elements may be arranged in a random manner. Crossed dipoles may be employed to make the absorption independent of the polarization of the incident radiation; alternatively this may be effected by using parallel electric and magnetic dipoles.

Title: Improvements in machines for grinding twist drills
IPC: B24B3/24
Filed: 1930-02-24
Abstract: 344,644. Sharpening twist drills. STOCK & CO., SPIRALBOHRER-WERKZEUG-UND MASCHINENFABRIK AKT.-GES., R., Marienfelde, Berlin. Feb. 24, 1930, No. 6097. Convention date, Feb. 27, 1929. [Class 60.] In a machine for grinding twist drills, the drill is held in a chuck on a stand 1, and is ground by a grinding-wheel 2 carried at the top of an arm 3 pivoted at 4 to the base of the stand, and oscillated across the work by a hydraulic drive carried by the arm. Within the arm is mounted an electric motor 6, which drives a pump 9 for supplying cooling fluid from a tank 1 to the work and which also drives, through a belt 7, the spindle 8 of the grinding-wheel. The spindle drives, through gearing 12 and a spindle 13, a pump 14 receiving fluid from a container 15 and delivering the fluid through a pipe 16 to a hollow spindle 17 upon which is pivoted a casing 18 for a driving piston 26 and a piston valve 31. The flow of fluid in the pipe 16 is controlled by a valve 21, Fig. 8, by which the fluid may be returned direct, through a bore 22 in the valve and openings 23, 24, to the container 15, thus stopping the movement of the arm 3, or may be throttled down to give slower movement. The piston 26 is connected by a rod 27 to a bell-crank lever 28 pivoted at 29 to the stand 1, and the rod 32 of the valve 31 is guided in the lever 28, the valve being moved to reverse the movement of the arm at the ends of its strokes, by a bell-crank lever 33, operated by a lever 42. This lever has an arm 45 which strikes stops 46, 47 adjustable on a screwed rod 48, and is thrown over by a spring plunger 50. The rod 48 is held against axial movement by a link 54 and carries a sleeve integral with the stop 47, so that partial rotation of the sleeve by a lever 57 moves the stop away from the path of the arm 45 and reversal of the movement of the arm 3 does not occur, the arm 3 being stopped in its extreme position, with the grinding- wheel 2 clear of the work, by a connection between the lever 57 and the lever 33, whereby the inlet and exhaust sides of the valve 31 are connected through bores 39, 40 in the valve. The valve has two operative portions whereby connections are made from the pressure inlet 19 from the spindle 17 to the ends of the cylinder 25, and from the cylinder to the exhaust outlets 38a communicating with the container 15. In a modification, the valve 21 is arranged in two spring connected parts so as to act also as a safety valve, and the valve may be operated by movement of the lever 57, the connection between the levers 57, 33 being omitted. A braking device, also actuated by the lever 57, may be provided, acting on the sleeve 51, whereby the motion of the arm 3 is arrested.
