Title: Forging method
IPC: B21J5/00
Filed: 1964-06-03
Abstract: 1,072,152. Forging; working at specified temperatures. MASSEY-FERGUSON Ltd. June 3, 1964 [June 17, 1963], No. 22895/64. Headings B3H and B3V. A hot steel or alloy steel workpiece 70 is forged between closed dies 18, 32 for at least one second in the temperature range of 1600- 1800‹ F. The workpiece, which is particularly of steel alloy, is pre-heated to 2100‹ F. in a salt bath containing sodium and potassium chlorides and is then coated with lubricant by immersion in a mixture of flaked graphite and potassium iodide or by dipping into dry flaked graphite. Dies 18, 32 made of heat-resistant metal or coated with a ceramic, are insulated from the press parts 24, 26, 34 by refractory layers 22, 30. Each die is surrounded by induction heating coils 60 containing cooling fluid passages 62 and a temperature control 68 determines the supply of heat energy from source 58 or water coolant from supply 64 so as to maintain the die temperature in the range 1600-1800‹ F. After insertion of the hot workpiece the dies are closed by a hydraulically operated platen 10 and a plunger 40 is then actuated through lever 42 by an hydraulic ram 48 to further upset the workpiece into the shape of the closed die cavity. Finally the workpiece is removed by an ejector 50 operated by lever 54 and cooled down to below the critical temperature in a salt bath or mica pit.

Title: Dehydrating apparatus
IPC: C04B11/028
Filed: 1958-07-16
Abstract: <PICT:0897923/III/1> <PICT:0897923/III/2> A dehydrating apparatus for gypsum comprises a rotatable chamber having an axial pipe bearing a hollow accordion-like structure serving to subdivide the gypsum mass, heating medium being passed into said axial pipe and the associated hollow structure, from which connecting pipes to the outside of the chamber may be provided.  As shown in Figs. 1 and 2, a drum 6 is supported by, and rotates about, an axial pipe 21 which rests on rollers 5. Inside the drum the tube 21 carries a hollow accordian-like arrangement of annular dished members 26 peripherally joined to form a series of chambers communicating with the interior of pipe 21 through perforations 25.  A gas burner 22 delivers a blast of hot combustion products into the pipe 21 from the left-hand side and these gases pass through perforations 25 into the chambers 33 formed by the annular dished members 26.  The chambers 33 communicate with tubes 8 (Fig. 2) formed in the walls 7 of the drum, by means of pipes 30.  Tubes 8 are provided with exhaust passages 31 having terminal elbows 32, whereby the hot combustion gases from chamber 33 pass through connections 30 into tubes 8 and out through exhausts 31 in contact with the exterior of the drum 6.  Gypsum is fed to the drum through removable closures such as 11 and the steam formed by dehydration is vented through valve 13. As shown in Fig. 2, the valve 13 is operated by a lever 16 carrying a roller 18.  The latter abuts a valve-operating cam 19 which is manually adjustable so as to release steam pressure as desired when the drum rotates.  In operation for the dehydration of gypsum, gypsum pieces having a maximum dimension of an inch are fed to the drum in an amount sufficient to permit relative movement between the pieces of gypsum on rotation.  The steam-tight closures 11 are sealed and the drum rotated.  The pressure rises to about 35 p.s.i.g. as the gypsum becomes heated and thereafter rises to about 40 p.s.i.g. as dehydration commences.  The cam 19 is thereupon adjusted to release the steam pressure and as dehydration proceeds, the valves 13 are progressively opened wider until at the end the pressure has dropped to atmospheric.  The drum may be preheated before introducing gypsum, to a temperature of about 300 DEG F.  During dehydration the temperature remains at about 250 DEG F. and may be raised to about 270 DEG F. at the end of the operation. Specifications 866,126, 897,924, 897,925, 897,926 and 897,927 are referred to.

Abstract: 1471438 Soldering SIEMENS AG 22 May 1974 [23 May 1973] 22947/74 Heading B3R In a method of manufacturing an article from a ceramic member and a metal member, one of which has an inner surface surrounding a portion of the other member, some but not all parts of the inner surface are soldered to respective opposing parts of an outer surface of the portion of the other member so that spaces for expansion of the solder are left. The ceramic member may be metallized prior to soldering. In the embodiment of Figs. 1 and 1a, five solder strips 3 are applied to a molybdenum pin 1 and an aluminium oxide tube 2 is mounted on it and the  assembly heated, In Fig. 3a metal body 5 has internal recesses 8 and portions 9 have solder layers 10 applied thereto. Ceramic body 6 is then fitted on to body 5. For the X-ray tube in Fig. 4 a metallizing strip, such as shown in Figs. 5, 6 or 7 is applied to ceramic tube 13 or 27 and a solder ring is applied to this and metal tube 12 is mounted on top. The assembly is then heated and the solder only "wets" the metallized portions of the ceramic tube. Typical suitable solders for this method are copper and nickelpalladium.

No. 23271. fClass 100 (iii).] Magazines ; escapements.-Means are provided for enabling either magazines provided with escapements or magazines unprovided with escapements to be used alternatively in the same machine, so that the magazines of machines of the kind known under the Registered Trade Mark " Intertype " can be used on machines of the kind known under the Registered Trade Mark " Linotype," and vice versa. (1) Sets of escapements D<1>, Fig. 2, are mounted in supporting bars E, which are hinged one to each magazine base-frame A, so that the escapements may either rest in operative position in the case of a magazine D, which is unprovided with escapements, or may be swung through an angle of 180‹ into an inoperative position in the case of a magazine C, which is provided with escapements C<1>. The escapement-actuating elements, which are mounted on fixed bars F, comprise series of vertically movable pawls H, pivoted to the free ends of levers H<1>, which can be rocked by push-rods H<5>. The pawls H are adapted to engage either the escapements D<1> carried by the hinged bars E, or the escapements C<1> mounted on the magazines C. (2) Each base-frame is provided with pivoted latches N, Fig. 1, which are engaged by one of the usual transverse bars K on the underside of a magazine C, to prevent the magazine from sliding forwards, these bars K being differently located from the corresponding bars J on the magazines D. The bars J of the magazines D depress the latches N and rest against the usual shoulders L. (3) As the longitudinal guide-bar on the underside of a magazine C is narrower than the corresponding bar on a magazine D, the groove L<1>, Fig. 9, in the base-frame, that accommodates the bars, is provided on either side with pivoted lugs O, which, when turned into operative position, reduce the width of the groove. (4) As the channels of the magazines C, D differ in spacing and inclination, the machine is provided with interchangeable magazine-entrances, such as those described in Specification 302,879, and a grooved guidemember P, Fig. 2, is located between the magazines and the assembler-entrance B, the grooves being arranged at inclinations intermediate between those of corresponding channels of the different magazines, and being preferably flared at their upper ends. Specification 14582/90, [Class 100, Printing, Letterpress &c.], also is referred to.
