Abstract: 1440543 Pigments BAYER AG 27 Aug 1974 [30 Aug 1973] 37387/74 Headings C1A C1N [Also in Division C4] A temperature stable yellow pigment has the composition Fe 2 TiO 5  .xTiO 2 , wherein 0<x#15 preferably 0À5 to 10 and especially 1 to 5 and has a particle diameter of less than 1 micron. The pigment may be made by suspending at least one of iron oxide, iron oxide hydroxide, iron hydroxide or iron carbonate in finely divided form and at least one of titanium dioxide or water containing titanium dioxide in finely divided form in accordance with the above stoichiometric composition, removing the aqueous phase and calcining the residue at 600 to 1100 C. for 0À1 to 10 hours and, if necessary, grinding to less than 1 micron. The first quarter of the calcination is preferably carried out in a weakly reducing atmosphere and to this end 0À1 to 10% by weight of a reducing agent may be added to the suspension. In one preferred embodiment a finely divided Fe 3 O 4  black sludge accumulating after nitrobenzene reduction with iron in concentrated FeCl 2  solution and a TiO 2  white sludge are formed into a suspension which is concentrated by evaporation, spray drying or filtering whereafter the residue is caleined, preferably at 750 to 1000 C. In an alternative embodiment a TiO 2  suspension is mixed with an iron (II) salt solution and the mixture is adjusted with alkali metal, ammonium or alkaline earth metal hydroxide or carbonate to pH values in the range 5-12 and the resulting mixed precipitate is separated and calcined as above.

Title: Improvements in or relating to tables
Filed: 1929-12-10
Abstract: 336,496. Kovats, J. Dec. 10, 1929. Folding tables. - In a table of the kind with legs separately pivoted to the underside, the legs are connected so that the movement of any leg is communicated to each of the other legs. Figs. 2 and 3 show a corner of a table top 12 with a rim 13, a pivoted leg 14, and a guide 29 for parts of the movementtransmitting devices. The leg 14 is secured in a U-section sheath 15 with ears 17, 18 by means of which the leg is pivoted to the ears 22, 23 on a bracket 19 screwed to the bars 13. When a leg is swung outwards about its pivots 24, the link or brace 43 causes the block 34 to move in the guide 29, and the cable 40 clamped to the block, passing over corner pulleys 45, transmits a similar motion to the similar blocks 34 and legs 14 at the other three corners. During this outward movement the pivot 42 connecting the links 41, 43 moves along the slot 29, the outer end of which has an inclined part 33, which is substantially at right-angles to the strut 43 in the position shown in Fig. 2. The leg is thereby held rigidly. The ends of the cable 40 are connected by parts 46, Fig. 6, with overlapping parts 47 each with a series of holes 48 through which a securing-screw 49 may be passed.

Abstract: 1496607 Radar BENDIX CORP 16 Sept 1975 [7 Nov 1974] 38039/75 Heading H4D In a D.M.E. radar, of the kind including a range clock 28, Fig. 1, started by the interrogation signal and stopped by the response signal, errors may be caused by the direct application of the interrogation signal to the clock, since this neglects the delays produced on the response signal as it passes through the IF stages &c. of the receiver before application to the clock. A sample 16 is therefore taken of the interrogation signal adjacent the T/R switch 12, which sample, after frequency shifting 17, 18 to the response frequency is injected into the input of the receiver. As the response 6, Fig. 2, may be contaminated by ground reflections 6b at its later part, a very low threshold 7 is used at 24 so that the pure leading edge 6a of the response is used to determine the response time t 1  for stopping the clock. If the injected signal-having the same shaped leading edge, but having a flat, uncontaminated later part, is of a different amplitude to the response, then, due to the sloping leading edge an error will occur in the corresponding threshold time-e.g. see differing times t 1 , t 2  for different amplitude responses. To overcome this sample and hold circuits 32, 34, in collaboration with detector 25 determine the peak level of the interrogation signal and the corresponding level of the response signal. A comparison is made at 36 and the amplitude of the output of oscillation 18 varied to equalize the levels.

A boring head comprises a spindle 17 rotated by a motor-driven belt and pulley 19, 18, a boring spindle 26 coupled to spindle 17 at 22, a tool-holder 40 having a roughing tool 43 and a finishing tool 44 secured to a pivot-pin 36, and means for pivoting the tools in directions A, B to vary the diameter of hole to be cut. Toolholder 40 has a forked end 46 which is integrally formed with an arm 50 which projects into spindle 26, and a similar counter-balancing arm 52 is pivotally carried by pin 36. The arms are normally held apart by a spring-urged cone 56, which seats in recesses 63, 64, in the arms and are moved together by wedges 71, 72, which engage bearing members 77, 78, carried in grooves 73, 75, in the arms. As the arms move together, arm 50 moves clockwise as shown in Fig. 1, and tool-holder 40 moves in direction B, thus increasing the cutting diameter of tool 44, and when wedges 71, 72 are moved to the right, spring 68 moves cone 56, thus pivoting the tool-holder in the direction A, to adjust the cutting diameter of tool 43. Wedges 71, 72 are integral with a guide 70 connected to an hydraulic piston 88 by a piston-rod 90, the piston being slidable in a cylinder 83, and the movement to the right, Fig. 1, of the piston, is limited by an adjustable stop 96. Stop 96 is screwed into a worm-wheel 98 and is non- rotatably held by a screw 99, and worm-wheel 98 is rotated to adjust the stop by a hand wheel 110 connected to a spindle 112 which carries a worm, the adjustment being indicated by a pointer 118. A boring machine is shown, Fig. 4, wherein the boring head is driven by an electric motor 124, and worm-wheel 98 is actuated by a servomotor 126. A workpiece 133 is held in an axially slidable work-holder 130, and a gauging device 140 is axially movable relative to the workpiece. In operation, after the roughing and finishing operations have been completed, gauge 140 is pushed into the bored hole, and if the bore is smaller than required, a current pulse is applied to a relay 143 through a timing device and the servomotor 126 adjusts the stop 96, thus adjusting the tool-holder to increase the size of the bore.

Filed: 1930-12-22
Abstract: 369,607. Wireless receiving systems. VERDAN, C. E., 40, Rue de Molsheim, Strasbourg, France. Dec. 22, 1930, No. 38615. Convention date, Jan. 14. [Class 40 (v).] To eliminate parasitic disturbances in a radio communication system the disturbances are utilized to interrupt reception for the duration of the interference thereby producing blanks in the received message, which are then restored by known fading-prevention means. A receiver 2, tuned to the same wavelength as the transmitter 1, actuates a signal recording device 12 through a relay 3. A second receiver 7, tuned to a different wavelength, actuates a relay 8 when affected by a parasitic impulse which affects 2, 7 simultaneously. The relay 8 disconnects the recorder 12 from the circuit of relay 3 so that a " blank " results from the parasite which thus has the same effect as fading. The receiver 7 may act on any part of receiver 2 to prohibit reception during a parasitic impulse ; also 7 may be combined with 2 in the form of circuits tuned to a wavelength other than that of the signal ; or two auxiliary receivers may be tuned one above and one below the signal frequency instead of one receiver 7. The principle may be applied to eliminate interference as from adjacent stations and is also applicable to telemechanics.
