Title: Improvements in or relating to radio-controlled remote selecting systems
IPC: H04W88/02
Filed: 1949-04-01
Abstract: 667,188. Electric selective signalling systems. STORE NORDISKE TELEGRAFSELSKAE AKTIESELSKAB. April 1, 1949. [April 2, 1948] No. 8973/49. Drawing to Specification. Class 40 (i). [Also in Group XL (c)] In a radio remote control system employing a carrier modulated by different low, e.g. audio, frequencies, the receiver comprises a chain of two or more relays 20 each controlled by a separate amplifier 18 responsive to one only of the frequencies and each relay has a holding circuit 22 connected over a contact 25 of any preceding relay, a control, e.g. alarm, circuit 32, 34 being closed when all contacts 30 of the relays have been connected up. If 10 modulation frequencies and three relays at called stations are used one of any 1,000 stations may be called. The amplifiers and relays being connected in parallel, operation of more than one relay each responsive to the same frequency at a station is avoided by making the duration of a call frequency less than twice, e.g. one and half times, the time delay of operation of an amplifier and relay, each amplifier screen grid circuit being connected up over a contact on any preceding relay. A further amplifier and relay responsive to a further tone may be arranged to call all the stations simultaneously. A frequency-modulated carrier may be used, and a squelch circuit, operated by the difference between rectified voltages derived from noise signals after the discriminator and from the carrier wave at the limiter, which operates a relay opening all the chain relay holding circuits if the carrier does not sufficiently exceed the noise level.

Title: Improvements in and relating to the driving mechanism of machine tools
IPC: B23D17/04
Filed: 1920-03-30
Abstract: 141,045. Tetetleni, A. Nov. 27, 1916, [Convention date]. Metal-working presses; shearing; punching.-The speed of a reciprocating tool of a shearing, slotting, punching, riveting, or other machine is varied during each stroke inversely as the variation in the resistance encountered by the tool. Known variable-transmission gear having, for example, tracks, guides, elliptical gears, &c. may be employed. As applied to a shearing machine, in which a pivoted toolholder or lever 2, Fig. 3, is oscillated by a rotating crank-pin 5 engaging a slot 4 therein, the necessary shape of slot is found in the following way. The distance of each point of the line P', Fig. 2, from the line 0-13 represents the resistance throughout a working stroke of length l. This length is divided into 13 parts #l'1, #l'2 - - #l'13 corresponding to equal work areas so that if the tool move through distances equal to these lengths #l'1, #l'2 ... in equal times the power used will be constant. A, Fig. 4, represents the pivot of the tool-holder 2 and C the shaft of the crank-pin 5 which travels in a circle M. 0, 1, 2, - - 13 represent corresponding positions of 'a point on the tool-holder or lever 2 and of the pin 5 after equal intervals of time. The trace K of the pin on the holder gives the form required for the slot. If that part of the line K through the points 9', 10' - - 13' doubles back closely on that through the points 9', 8', 7' ... a simple slot 4, Fig. 3, may be used as an approximation instead of a closed curve. By reducing the length 13-0 traversed by the crankpin during the return, or by bringing the points A, C closer or both, a very quick return may be obtained. If the pin 5 only oscillates, the slot takes an ogee form. In order to correct inexactitude in the mechanism, the lever 2 may carry one or more pins 11, 19, 20, Fig. 11, to engage slots 12, 21, 22 in secondary levers 9, 23, 24 operating tools such as shear blade 1, punch X, and section cutter Y or a secondary lever may actuate a third and so on. In order to adapt a machine for different work, the slots may be formed in removable flanged plates 14, Fig. 9, secured by wing-nuts 17, so that they can be changed.

Abstract: 399,536. Partitioned boxes. AUSTIN. E. L., 183, Wimbledon Park Road, Southfields, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, both in London, March 30, 1932, No. 9209. [Class 18.] A multi-compartment box intended for eggs, ornaments, &c. has some of the partitions between compartments formed from blanks of cardboard or other suitable material which are cut and bent to form base portions having a number of internal upwardly projecting tongues, while the remaining partitions are formed by strips passing between adjacent coplanar tongues. The blank shaped as shown in Fig. 1 is cut along the full lines and bent along the dotted lines to the form shown in Fig. 2. The device is then placed in a box and divides it into 6 compartments, the partitions being formed by the internal upwardly directed tongues 4, 5, 6 and the strips 9, 10. Two such members placed in a box with the free ends of the strips 9, 10 facing one another and separated by a plain division strip form a box with 12 compartments. In a modification, the strips 9, 10 are extended, the extensions being bent outwardly at right angles from the strips, so that two of the devices placed in a box facing in the same direction, form 12 compartments without a division piece. In a further modification, shown in Fig. 5, an extension member 38 on the base is provided and similar extensions on each side of the member 38 may provide bases for the outer compartments in the second row. The internal upwardly extending tongues may, if desired, have any shape other than rectangular. The device may be suitably modified to form boxes with multiples of three of other odd numbers of compartments. For 5 compartment rows the strips 9, 10 may be extended and bent round outside the tongues 4, 6 or strips 9, 10 may be provided on each side of the base portion, one pair of strips being bent to embrace the second of the five tongues in the base portion, and the other pair being bent from the opposite side round the fourth of the five tongues.

Title: Producing niobium alloys
IPC: C22C27/02
Filed: 1935-03-26
Abstract: Materials containing niobium oxides are reduced with silicon or silicon alloys, such as ferrosilicon, chromium - silicon, ferrochromium-silicon, niobium-silicon, or alloys with other metals unobjectionable in the final product.  The amount of silicon in the charge is preferably adjusted to yield an alloy with a niobium to silicon ratio of between about 6 : 1 and 12 : 1, in particular between 7 : 1 and 9 : 1, whereby upwards of 75 per cent of the metal may be recovered and the niobium oxide is selectively reduced in preference to the oxides of tantalum and titanium present.  Iron, nickel, chromium or other metals may be added to the product either by reducing in the presence of a metal bath or making the addition during or after the reduction.  Slags obtained containing substantial amounts of niobium, tantalum, and titanium may be smelted with enough silicon to yield a niobium-silicon alloy of a less ratio than 6 : 1, this product then being used as reducing agent for niobium oxide-containing material to form the lower silicon alloy.

Title: Process for decomposing co-containing cobalt compounds in products obtained in the oxo-reaction
IPC: C07C45/50
Filed: 1950-04-17
Abstract: Oxo reaction products prepared in the presence of a solid cobalt-containing catalyst are treated to decompose cobalt compounds and remove liberated CO by cooling to a temperature which is below the reaction temperature and in no case exceeds 120 DEG  C., and maintaining at this temperature under a pressure of 1-10 atm. while passing a flushing gas which may be or contain H2, N2, CO or hydrocarbons.  An olefinic material may be mixed with finely-divided cobalt catalyst and passed with H2 and CO into a high-pressure reactor at 130-180 DEG  C.  The product is cooled prior or subsequent to releasing the pressure and passed to a tank at, for example, 80-120 DEG , particularly 95-105 DEG  C., while passing a flushing gas for 1 or more hours.  A series of tanks may be alternatively used as decomposing, waiting, and feed tank for further hydrogenation to alcohols or continuous operation may be effected in a bubble tower. Separation of the product from suspended metal or carrier material may be effected subsequent to the decomposition.  In an example, C6-C8 olefins are reacted at 140-160 DEG  C. and 200 atm., and the product treated at 100 DEG  C. and 1 atm. with H2.

Abstract: 325,155. Rogers, F. H., (Goring & Severin Maschinenfabrik). March 25, 1929. Severing; driving devices. - In a belt-driven machine for severing by means of a thin grinding-wheel, the circumferential speed of the wheel, as this wears, is kept within predetermined limits by the provision on or near the wheel of marks indicating diameters at which the rotational speed must be increased, or by means of a feeler for testing the diameter, the movement of the feeler causing a corresponding movement of the driving bedt to increase the speed. In one constructional form, Fig. 2, the grinding-wheel 5 is mounted on a shaft 6 carrying a pulley 7 driven by a belt 8 from a pulley with three steps 2, 3, 4 and mounted on a shaft 1, the belt being tensioned by a device 9. Upon the wheel 5 are three coloured rings a, b, c, and when the diameter of the wheel is reduced to the diameters indicated by the rings, the belt 8 is moved on to the next larger pulley step; the rings may be replaced by dots &c., and may be on a bar placed at the side of the wheel. In another form, Fig. 4, the drive consists of two reversely arranged cone pulleys 12, 13 connected by a movable belt 14, and the drive to the shaft 6 of the grinding- wheel 5 is taken through a step-up belt drive 15, 16, 17, 19, 20 to a pulley 7 on the shaft 6. The diameter of the wheel 5 is tested periodically by a feeler disc 23 mounted on one end of the arm 22 of a lever pivoted at 21, a weight 24 normally lifting the feeler clear of the wheel 5. On depression of the feeler, the belt 14 is moved along the pulleys 12, 13 by a fork 30 on a bar 29, which is moved by the lever 22 through an arm 25 and a lever 27 pivoted at 26, the lower arm of the lever 27 engaging a stud 28 on the bar 29. Visual or audible signals may be given after a predetermined number of revolutions of the wheel to indicate that the diameter of the wheel 5 should be tested.
