Title: Improvements in the manufacture and production of metals, metal mixtures or alloys
IPC: C22C33/02
Filed: 1931-04-02
Abstract: In a process for the production of metals such as chromium, manganese, zinc, copper, titanium, molybdenum, and tungsten by the reduction of their chlorides by means of iron, nickel, or cobalt, chlorides of iron, nickel, or cobalt together with smaller amounts of chlorides of chromium, manganese, &c. are sublimed off and may be collected in coolers, washers, &c.ALSO:Metals, alloys, or mixtures of metals are obtained by treating iron, nickel, or cobalt in powdered or molten form with a chloride of a metal having a specific gravity of at least 4,5 and a potential below 0,79 volt, for example chromium, manganese, zinc, copper, titanium molybdenum, or tungsten, at about 900 DEG  C., preferably in an inert or reducing gas.  The method is particularly applicable for the preparation of alloys of chromium, molybdenum, or titanium with iron, nickel, or cobalt. For example, a mixture of chromium chloride with iron powder obtained from iron carbonyl may be treated in such proportions as to yield a carbon-free alloy containing about 96,8 per cent of iron and 3,1 per cent of chromium.  An alloy containing 85,2 per cent of iron and 14,4 per cent of manganese may be similarly p  obtained.  The chlorides of iron, nickel, and cobalt, together with smaller amounts of chlorides of chromium, manganese, &c. are sublimed off and may be collected in coolers, washers, &c.

Title: A method of unwinding textile packages
IPC: B65H49/28
Filed: 1959-03-26
Abstract: 908,781. Unwinding yarns &c. FLEISSNER & SOHN G.m.b.H. & CO. March 26, 1959 [April 30, 1958], No. 10534/59. Drawings to Specification. Class 120 (2). Yarn &c. is unwound from a package by withdrawing it at constant speed from the inside of the package which is mounted on a turntable driven at a speed or speeds between the maximum and minimum angular speeds at which the point of withdrawl would rotate if the yarn &c. were withdrawn at the same constant speed from a stationary package, whereby the point of withdrawal is stationary at least at one point of time during the unwinding. The speed of the turntable may be reduced during the operation, e.g. so that the product of the speed and the corresponding diameter remains constant, gradually or in steps ; for this purpose, infinitely variable control means or a time switch, feeler or photo-electric device acting on change-speed gears, resistors for the driving- motor or braking devices may be employed. The drive to the turntable may be cut off at a given instant by one of these devices. When the turntable is driven at instant speed, the latter can be related to the speed of rotation of the draw-off point at a diameter which may be the arithmetic or harmonic mean of the inner and outer diameters of the package.

Title: Improvements in or relating to electrical remote control systems
IPC: H03J1/22
Filed: 1938-04-07
Abstract: 513,336. Electric control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and OLIVER, E. C. April 7, 1938, No. 10657. [Class 40 (i)] In a remote control system for selecting a set of operations from a plurality of possible sets of operations, a first switch at the controlling station actuates an operation relay at the controlled station for effecting a common initial operation and prepares a relay chain, a dialling device being arranged to send impulses over the two-wire line between the stations to operate the relay chain to select and operate an operation relay, a second switch being provided to actuate another operation relay for effecting a common final operation. Upon the " Fils. On switch being operated at the controlling point relays NT and G pull up in turn to operate the corresponding transmitter contactor. Two to ten impulses are now sent over the line by a dial switch according to which contactor it is desired to operate, G remaining operated due to its slug. When the line is de-energized, NT releases, relays M, E and C operating, and upon the line being re-energized, NT pulls up and relay P operates in series with M and locks up, M releasing. E and C remain operated and when the line is next de-energized, relay N is operated, and upon the line being re-energized, relay Q operates in series with N. N and P then releasing. In this manner, the counting relays P, Q, R, S, T, U are operated in turn. If it is desired to select wave 1, five impulses are dialled and at the end of the impulse train, T alone remains operated in the counting relay chain. As M releases E is de-energized and E and C fall away in succession, in the interval, relay IW locking ups and operating the wave 1 contactor. When a train of impulses in excess of five is sent, relay U locks up, the other relays being again operated in turn, so that when ten impulses are dialled, S and U will be operated at the end of the train, and relay 2P will be locked up. In this way by dialling three numbers, one each of the three groups of relays controlling the transmitter contactors will be locked up. In order to apply the power, the "power on" switch is operated causing relay RT to operate which also maintains G operated. If it is desired to alter the contactor operated in a group, impulses corresponding to the desired contactor are sent, when the corresponding relay will be operated, releasing the previouslyoperated relay, one contact of which will then allow the relay to lock up. When the telegraph key is operated relay K operates. The lines may be used for telephonic communication using the transformers shown.

Title: Method and apparatus for producing book sections from printed paper webs
IPC: B42C3/00
Filed: 1976-03-18
Abstract: The web of paper (1) which is folded and possibly cut longitudinally in the former (92) is cut transversely (5, 6) to the book length and moved onto a collecting cylinder (9) for collecting layers of paper. The latter are passed onto a transfer cylinder (12), bound longitudinally thereon by means of a device (13), then folded longitudinally (15) and delivered (19). The collecting cylinder is designed for the largest format to be processed. The transversely cut sheets of paper are conveyed to the collecting cylinder (9) by means of a conveyor belt (7) which can run at various speeds. As a result, shorter or longer sheets of paper can be fed more rapidly or more slowly to the collecting cylinder (9), and the subsequent transfer cylinder (12) also runs at an adapted rotary speed. The subsequent longitudinal folding takes place by means of a rotating folding blade (15). A higher throughput can thus be achieved in a simple manner since solely rotating members (5, 6, 7, 9, 12, 13, 15) are used. <IMAGE>
