Abstract: 1290859 Controlling discharge of an endless conveyer at successive points ASSOCIATED ELECTRICAL INDUSTRIES Ltd 16 Oct. 1970 [17 July 1969] 36082/69 Heading B8A A control arrangement for a conveyer for distributing articles from a despatch point 10 to a plurality of destinations, comprises a sue-. cession of electric data stores 6, 7, 8, each associated with a respective portion of the conveyer, means to apply in turn to the first of the succession of stores, code signals corresponding to the required destination of articles placed on the conveyer at the despatch point, a respective counter 13, 19, 20, associated with each of the stores which is stepped by clockpulses substantially synchronized with the motion of the conveyer and under the control of which a destination code signal is transferred from the respective store to the next succeeding store after an interval corresponding to the time of travel of an article over the associated portion of the conveyer, and gating means 26 associated with at least some of the stores. Each of the gating means is responsive to destination codes present in the associated store, to a particular state of the associated counter, and to timing pulses, to derive signals for controlling the operation of means for selectively removing articles from the conveyer. The timing pulses have a repetition rate, or are phased, to permit timing of the operation of the gating means at intervals which are substantially equal to, or sub-multiples of, the clock pulses. The clock pulses and timing pulses are derived from a clock pulse generator 15 which is driven by an electromagnetic pick-up 14 mounted adjacent a toothed wheel (not shown) which is mechanically coupled to the conveyer. There are three interlaced trains of pulse outputs 16, 17 and 18, each corresponding to a conveyer travel of three inches. Due to the interlocking, the pulse of two of the three outputs are delayed with respect to the third by two inches and one inch respectively. The destination of articles is determined by operation of a keyboard 1. A check of the operation of the removal of an article from the conveyer is provided by a pulse generator 29 which operates an alarm (not shown) when the article reaches its keyed discharge point (if it is not discharged as intended).

Abstract: 1295216 Hydrostatic extrusion ALLMANNA SVENSKA ELEKTRISKA AB 26 May 1971 [27 May 1970] 17157/71 Heading B3P An hydrostatic extrusion press of the type with a pressure cylinder 2 movable axially in a press stand 1 over a billet 36 and a die 10 before the cylinder is filled has a mandrel assembly composed of a headed mandrel 23, a holder 24 and a support tube 22. The assembly is permanently fixed in the cylinder and the tube limits the insertion of the die into the cylinder to position the die and the mandrel for tube extrusion. The support tube 22 takes up the forces exerted on the mandrel 23 during extrusion. An annular billet holder 30 is slidable on the mandrel 23. The billet holder 30 has a spring-biased relief valve 33 or a pair of elastomeric flanges (34), (35), Figs. 5 and 6 (not shown), so that initially the fluid pressure in the space 6b causes the billet holder to urge the die and the billet against a die holder 11 until the valve opens or the flanges deform. The fluid is thus initially prevented from reading the cylinder space 6b to avoid unnecessary cooling of the billet by the fluid.

Abstract: 1308619 Pulse radar MARCONI INTERNATIONAL MARINE CO Ltd 25 June 1970 [7 Nov 1969] 54559/69 Heading H4D In a P.P.I. mobile radar display the heading marker is of full predetermined brightness only during regularly occurring but not consecutive azimuth scans. The brightness may be manually adjustable; and the display may be of the relative or compass-stabilized or true motion kind. In an embodiment a known circuit incorporates a switch 1 which is closed momentarily when the aerial sweeps through the ship's heading, a switch 2 for disabling production of the heading marker and a circuit including a transistor 4 and a bi-stable 22: assuming switch 3 is in the R.H. position-corresponding to normal operation i.e. a heading marker pulse appearing at output terminal 23 for every azimuth scanwhen switch 1 closes, the base of the transistor is pulsed negatively thereby producing a positive differentiated output pulse which triggers bistable 22. The added circuitry in accordance with the invention includes a potentiometer 24, 25, 26, a network 27 ... 32 and a siliconcontrolled-rectifier (SCR) 35: with switch 3 as shown and when switch 1 first closes, the ensuing insertion of resistor 9 across resistor 24 causes the cathode side of diode 27 to fall sharply to near earth potential, that diode conducts and a positive undifferentiated pulse appears at the collector of the transistor. Such positive pulse causes the SCR to conduct, and capacitor 31 begins to charge and after about two seconds diode 27 is cut off. When switch 1 closes for the second time the SCR is cut off and capacitor 31 discharges but diode 27 remains cut off as switch 1 closes for the third time, and conduction of diode 34 causes faster discharge of capacitor 31. By the time switch 1 closes for the fourth time diode 27 is conductive, a negative pulse is applied via elements 28, 6, 5 to the base of the transistor and a positive, differentiated, pulse triggers circuit 22 to cause production of a heading marker, and a positive pulse is applied to "start" the SCR. The whole cycle then repeats. Heading marker brilliance can be adjusted by the circuit 40 ... 43.

The boriding agent is produced by igniting amorphous boron at 850‹ to 1100‹ C. for 1 to 3 hours while a rare gas is simultaneously conducted through the boron, which is thereafter cooled with the further conduction therethrough of rare gas. The boriding agent may be providing with activators which increase the thickness of the hardened skin produced by the boriding agent on the treated material. Examples of activators are alkali metal, alkaline earth metal and ammonium halides. Also an inert substance which acts as a thinner, e.g. stable oxides, talc and asbestos may be included in the boriding agent. Titanium or titanium alloy workpieces when borided by this method generally have a hardened surface with a thickness of 0À04 to 0À1 mm. comprising the titanium borides TiB 2  and TiB. During the boriding operation, which occurs at 900‹ to 1400‹ C. for at least 3 hours rare gas is constantly conducted through the boriding agent in a vessel only with an inlet and outlet for the rare gas. The material is then cooled.
