Abstract: 361,889. Printing - machines. THOMPSON & SON, Ltd., T. C. and THOMPSON, F. S., 26, Buxton Street, London Road, Manchester. May 24, 1930, No. 15992. [Class 100 (ii).] Tripping and like arrangements ; platen machines. -In a platen printing-machine of the kind having a fixed type bed and a movable platen 7 carried by a swinging frame 6, the platen is fitted with a throwoff device which operates without altering the normal open position of the platen. The construction also permits of adjustment of the impression position of the platen, and the throw-off mechanism when operative acts to trip the platen just before it reaches the closing position, and to untrip the same just after the platen commences to open. As applied to a machine of the kind described in Specification 312,025, [Class 100 (ii), Printing processes &c.], in which the frame 6 is operated by a link 10 and bell crank 11a, the frame 6 is mounted on an eccentric bearing 8 carried by a shaft 9. A projection on the lever 11a is connected by a link 15 to a striker lever 14 freely mounted on a shaft 13 and capable of engaging a pawl 17 on a lever 16 freely mounted on the shaft 13. A cam 32 is operated by a rod 33 connected to the cam by a spring-connection, and if the impression is to be thrown off, the pawl is allowed to engage the lever 14 and the lever 16 is moved clockwise as the platen closes. A slot 16a in the end of lever 16 acts on a pivot pin 18 to move toggle levers 19, 20 out of their normal straight position shown in Fig. 1, and a connected bell crank 24 is moved clockwise around the shaft 13, and by means of a link 25 the bearings 8 are moved clockwise to throw off the impression. A spring 27 restores the toggle levers 19, 20 to normal position as the platen opens. This spring maintains the lever 19 normally against a fixed stop 29. The lever 19 is pivoted to a bell crank 21 connected to a screwoperated adjusting rod which controls the normal impression position of the platen. Reference has been directed by the Comptroller to Specifications 1903/99, [Class 100, Printing, Letterpress &c.], and 178,080, [Class 100 (ii), Printing processes &c.].

Title: Improvements in or relating to process for the reduction of carbon content of ferroalloys
IPC: C21D3/04
Filed: 1955-06-07
Abstract: A process for reducing the carbon content of ferro-alloys, e.g. ferro-chromium, containing 4-10 per cent of carbon comprises, roasting millscale under oxidising conditions at a temperature, e.g. 750-1500 DEG C, and for a time sufficient to burn off oily and other combustible materials contained therein and to oxidise the millscale, mixing the finely divided roasted millscale with the ferro-alloy and heating the mixture under low sub-atmospheric pressure and at a temperature below that at which fusion occurs to oxidise the carbon. The millscale, before or after roasting, may be treated to remove metallic particles by a gravity, flotation or air classification method.  The mixture of millscale and ferro-alloy is preferably agglomerated e.g. with a binder such as dextrin and water.  The resulting briquettes are dried, heated in air to 500 DEG C for 12 hours to drive of volatilizable binder components and then subjected to vacuum furnace treatment to remove carbon from the alloy.

Title: Gas flow control valve assembly
Inventor: HEISER FERDINAND FRANK
IPC: F23Q9/10
Filed: 1955-06-07
Abstract: 811,710. Controlling gas burners. A-P CONTROLS CORPORATION. June 7, 1955, No. 16336/55. Class 75(1) [Also in Groups XIII and XXIX] A gas flow control valve comprises a body having an inlet 11 containing a pilot burner flame safety valve 12, a main burner outlet 44 and a pilot burner outlet 33, a manual valve 24 including a conduit 25 leaving the body downstream of valve 24 and re-entering the body at a chamber 43 connected to outlet 44 and a valve stem 53 carrying two valves 45, 46 controlling two seats 47, 48 in series in the conduit, so that valve 45 seats first and further stem closing movement takes up lost rotion at 50 to seat valve 46. On turning cock 24 to pilot position and depressing the knob 34 a rod 38 turns a lever 40 to open a valve 12 so that gas from the inlet passes via valve 12 and passages 26, 27, 28, 30 to the pilot burner. With the pilot burner alight a thermal couple 16 energizes a magnet which holds an armature of the valve 12 and keeps this valve open. Gas passes a pressure regulating valve 18 through the open valve 24 to the conduit 25 and past the valves 45, 46 to the main burner outlet. When e.g. room temperature increases, the bulb 57 and bellows 60 rotate a lever 62 in an anti-clockwise direction about a pivot 63 against the force of an adjustable temperature setting spring 65 and against a spring 72 through a roller 75 co-acting with a cam 69 on the lever 62. Movement of lever 62 is communicated via over-ride spring 77 and adjustable stop 78 to lever 76 and stem 53 to move valve 45 from an open, high fire position towards a closed position in which gas is supplied only through the by-pass 55 and open valve 46 to give an intermediate fire. Should room temperature rise unduly the lever 62 is then moved so that the roller 75 snaps over the cam peak 70 and moves valve 46 to its closed position. When the bulb 57 calls for heat, the roller snaps from the cam 71 to the cam 69 so that the valve snaps from full off to full on position. The device 64 may be removed from the unit body 10 and be replaced by an expanding wire thermal element actuating the valve through a compound lever system and being heated by a resistance wire connected to a thermial couple. In this case a spring loaded stop allows the thermal element to actuate the valve between full on and full off or between full on and intermediate fire.

A copy is made of an original 10 having a radiation-absorptive heat-generating image 15 containing a volatile constituent by placing the original against surface of a non-absorbent copy-receiving member 11 irradiating the image with radiant energy 13 absorbable by the image material to deposit a condensate image 16 of the volatile constituent on the copy receiving member, at least one of the original or copy receiving member being transparent to said energy, and developing the image with a particulate material. The original may be newsprint and the radiant energy may be light or infra-red. The copy-receiving member may be glass or a thermoplastic sheet such as cellulose acetate and the developed image may be fixed thereto by heating or by spraying with a transparent lacquer or plastic spray. Development may be conducted using charcoal, a xerographic resin toner or crystal violet dye powder, when a spirit duplicating master is obtained, or with a magnetic brush, Fig. 2 (not shown), and carbonyl iron powder. When the copy-receiving member is a transparent acetate or polyethylene film the developed image may be used as a diazo duplicating master. The copyreceiving member may be the final copy or the developed image may be transferred by contact and pressure to another surface, e.g. paper. Thus the image may be developed with carbonyl iron powder, transferred to a polyethylene sheet or paper, Fig. 3 (not shown), coated with polyethylene by pressure, the powder becoming embedded in the polyethylene to give a duplicating master which may be used with a water-based ink.

Filed: 1971-05-25
Abstract: 1352544 Digital electronic clock GENERAL ELECTRIC CO 25 May 1971 [5 June 1970] 16887/71 Heading G3T Relates to a digital electronic clock substantially as described in Specification 1341252 wherein a plurality of binary counters formulate a digital representation of time e.g. on 7 bar a display device, but since the said counters are capable of assuming states representing none time indicating numbers (such as 10, 11, 12, 13, 14 and 15) the present specification provides an impossible time correction circuit comprising NOR gates 211 to 216 Fig. 1 which respond to all improper time indicating numbers and apply a higher than normal repetition rate signal to a respective counter to advance it to a time indicating number. A gate setting circuit 15 is substantially identical in form and operation to that in the copending application except that the NOR gate 216 replaces inverter amplifier 303 thereof. NOR gate 211 is responsive to improper codes or numbers 12 to 15 regardless of which counter 27, 59, 77,33 or 113 has its output presented by switch matrix 53 to the time display device (not shown) via lines 159, 161, 163, 165. Thus when the output on leads 163, 165 are both "O" gate 211 produces a "1" output so that gate 214 output is "O" and gate 215 is enabled to pass high frequency correction pulses from the strobe source at line 135 to the circuit 15. NOR gate 212 is responsive to improper numbers produced by the ten minute counters 33 or 59, presenting a "1" output to gate 214 which again produces a "O" to enable 215 to pass the h.f. correction signal to circuit 15. NOR gate 213 likewise responds to improper counts from minute counter 27 and since gate 211 responds to improper numbers 12 to 15 then gate 213 is arranged to recognize only improper numbers 10, 11. To prevent the impossible time correction circuit responding to transiently appearing incorrect numbers, e.g. derived from the counters, a delay is included by adding a 60HZ square wave signal to a gate 305 which passes the h.f. strobe signal only when the 60 HZ signal is in its "O" state, as illustrated in Fig. 2 (not shown).  Alternatively, the gates 211, 212, 213 may be AND gates and the inverters 217, 218, 219 eliminated; also NOR gate 214 may be replaced by an OR gate and inverter.
