Abstract: 659,823. Making discs; forging-dies; forging- machines; shearing. HATEBUR, F. B. Dec. 31, 1947, Nos. 35225 and 35226. Convention dates, Nov. 7, 1941 and Sept. 5, 1942. [Classes 83 (ii) and 83 (iv)] In making a disc-like article from rod, a length thereof is fed between a pair of dies and upset by their relative movement, one of these dies being moved during the initial stage to increase the volume of the die cavity. The machine has rod feeding, shearing and blank transferring means operating with the dies in timed sequence. A rod S, Fig. 4, is fed against a stop 36, vertically adjustable by a wedge 38 and an inclined face 37 of a lever 31 pivoted to a slide 27. This is then moved to the left to cause a blade 26 to cut off a blank and bring it into line with the bore of a die 1, the upper die 16 being moved aside out of the way. A hammer 40 carried by the slide 27 then strikes the lever 31 and forces the blank into the die 1. The slide 27 is then withdrawn and the die 16 moved back into line with the die 1 and down to engage and press this down against the action of springs 12. The axial rod 3 being stationary during this action causes the blank to be forced out of the bore and upset thereby forcing the dies 1, 16 apart. When the die 1 engages the bottom block 9 it is arrested and, the die 16 continuing its downward movement, the blank is further upset to fill the recess 15. The die 16 is then raised and the rod 3 is forced up to eject the finished disc. The apparatus described in Specification 659,822 is also described but it is stated that the upsetting die 13 in Fig. 2 of said Specification, against which the blank is fed by the .ram 15, is first advanced and then withdrawn slightly during the upsetting process and is then advanced again to press back the ram to a position flush with the face of the fixed die. The Specification as open to inspection under Sect. 91 describes this machine with reference to an additional Figure which shows some of the operating mechanism. This subject-matter does not appear in the Specification as accepted.

Abstract: 786,477. Magnetic compositions. BADISCHE ANILIN- & SODA-FABRIK AKT.-GES. Dec. 9, 1955 [Dec. 10, 1954], No. 35370/55. Class 38 (2). A magnetically soft or hard ferromagnetic ferrite is made by a process including the step of melting metal oxides by heat developed in passing low-frequency alternating electric current through them. To make a manganese zinc ferrite suitable quantities of Fe 2 ,O 3 , MnO 2  and ZnO are placed at b in refractory crucible a with an iron strip d embedded therein and connected at its ends to electrodes c. When A.C. from a regulatable transformer is passed through strip d the latter first heats and then melts, the heating process being continued by passage of current through the oxide mixture now at a temperature at which it is conducting. Oxygen may be blown on the mixture b. When the mixture is molten, slide e is moved to disclose a hole through which the melt passes either into a mould or on to an iron plate where it cools rapidly and is quenched with a water-spray to render it friable. The product is then ground dried, compressed, with or without a binder, sintered and cooled rapidly in air. The melt may be separated from the crucible walls by unmelted oxides or ferrite particles. Scrap ferrite can be added to the melt. The manufacture of nickel-zinc, magnesium-zinc, manganese, barium, strontium, and cobalt ferrites is referred to.

Abstract: 996,444. Telegraphy; pulse circuits. SIEMENS & HALSKE A.G. Sept. 6, 1963 [Sept. 6, 1962] No. 35380/63. Headings H3P and H4P. [Also in Division G4] In a system for converting from binary double frequency or Williams code to another code means is provided for deriving clock pulses from the code. The double frequency code 1, representing binary data 2, provides a pulse 3 at each transition. These pulses are distributed to, in the embodiment described, five monostable units having a period of 1À35 T, where T is the bit period. Whenever three of these units are concurrently giving an output the second unit of these three is reset at the same time as the first unit resets. The resetting pulses provide a regular clock train 9. The circuitry comprises a number of bistable units, gates, and monostable units or counters, Fig. 3 (not shown). Conversion to the three output waveforms 10, 11, 12 is described. By setting a bi-stable unit with pulses 3 and resetting by pulses 9 waveform 10 is obtained. If two pulses 3 occur between two pulses 10 a bi-stable unit is set and reset to provide a return-to-zero duration significant output 11. By the combination of 10 and 11 in a one-bit generator a non-return-to-zero output 12 is obtained. The double frequency signals are obtained from a magnetic tape, drum or disc store. When the " start " switch is operated the tape motor is started but the read-out command is given only after a delay sufficiently long for the tape to have attained full speed.
