Title: Improvements in and connected with veneer presses
IPC: B30B1/00
Filed: 1930-10-20
Abstract: 365,552. Mechanical presses. LACEY, E. G., 10, Victoria Crescent, Abbotsford, Victoria, Australia. Oct. 20, 1930, No. 31450. Convention date, Nov. 22, 1929. [Class 87 (ii).] A veneer &c. press comprises thin metal envelopes between which the sheets are assembled and to which heated pressure liquid is admitted. The envelopes are assembled between adjustable upper and lower frame members, and are connected with a source of pressure liquid and exhaust, the connections comprising a byepass whereby the temperature and pressure may be controlled. The press comprises frame-members 10, Fig. 1, on which a deck 14 lined with metal 15 is supported. A similar lined deck 30 is supported on frame members 27 which are adjustable vertically by means of screwed shafts 16 operated by bevel gearing from a hand-wheel 24<1>. The envelopes 36, the sides of which are convex, are supported by slotted links 34 and are connected at one end to a common pipe 42 supplied with water under pressure which is heated by being passed through a heater core 44. The other ends of the envelopes are connected with a common discharge 52 ; the byepass 56 is controlled by a cock 57, and a thermometer 54 and pressure gauge 55 are provided in the discharge pipe 52. The rate of discharge may be gauged by means of a fitting shown in Fig. 7 and consisting of a perforated pipe with a closed end; as the rate increases the water issues from an increasing number of nozzles.
Patent GB-391514-A (GB)
Title: Improvements in and relating to the production of zinc white
IPC: C01G9/02
Filed: 1931-11-13
Abstract: In the continuous production of zinc white, metallic zinc is vaporized in a rotary chamber in the presence of sufficient carbonaceous material to provide a local reducing condition about the zinc and to prevent the formation of any free pool or bath by the distribution <PICT:0391514/III/1> of the molten zinc about the carbonaceous material.  The carbonaceous material used may be partly replaced by lump material such as firebrick.  Vaporization is effected wholly or mainly by heat derived from the partial combustion of the vapours above the charge, which are then carried by the air current into an adjoining combustion zone where complete combustion is effected preferably by the admission of secondary air, the vapours being subjected to a symmetrical gradation of temperature.  The process may be carried out in a rotary cylinder comprising a vaporizing zone b and a combustion zone c, Fig. 2, or two separate juxtaposed cylinders may be used.  The zone b is initially heated by a burner g and the zinc and carbonaceous material are charged by a shoot e, comprising a nest of water-cooled pipes.  Secondary air is admitted to zone c by adjustable valves i.  As shown in Fig. 1, the oxide vapours pass up a water-cooled tower B provided with an internal water-spray, and thence through cyclone separators C, D to a baghouse F.  A fan E serves to induce an air current through the whole apparatus, the effective suction at the outlet of the combustion zone being varied if desired by providing an adjustable opening at the foot of the tower B.

Title: Self-filling fountain pen
IPC: B43K5/04
Filed: 1931-11-16
Abstract: 385,403. Fountain pens. TIBALDI, G., 3, Via della Querce, Florence, Italy. Nov. 16, 1931, No. 31659. Convention date, Jan. 9. [Class 146 (iii).] In a self-filling fountain pen, the deflation of the sac is effected by distorting an element by rotation of a member engaging with the barrel by a screw thread of rapid pitch, rotation being effected by means of a second member rotatable in the opposite direction on the barrel. As shown, the sac l carried by the nib-section f is deflated by a rigid presser-bar n riveted to a spring o. The forward end of the spring rests against the end of the nib-section, and the rear end is bent to lie in a central cavity in a member k, or in an aperture in a loose block mounted in the cavity. The member k is provided with an external screw thread of steep pitch engaging a correspondingly screwed aperture in the end of the barrel. The member k is formed with a head k<2> adapted to engage the end of the barrel to limit the inward movement of the member, and the head is slotted to accommodate a transverse pin p secured in a cap h formed with a screw of normal pitch but oppositely directed to that on the member k. By unscrewing the cap h a short distance, the member k is moved forward a greater extent to cause the spring o to buckle and depress the presser-bar n. The rear end of the spring is curved longitudinally to increase its rigidity.

Title: Process for drying cellulose material
IPC: D21F13/00
Filed: 1972-07-06
Abstract: 1345501 Drying by displacement of water JEUMONT-SCHNEIDER 6 July 1972 [22 July 1971] 31730/72 Heading F4G Fibrous cellulose material 1 (the electrical insulation of electrical transforming, converting and inductance equipment) is dried by placing the material in a chamber 2 under a vacuum and contacting the material with dry ethylene glycol diacetate (EGD), the temperature of the EDG as it enters the chamber 2 being initially 60 to 70 C. but being increased as drying proceeds to between 100 to 110 C., the chamber being maintained at a vacuum equal to the vapour pressure of the EGD, and the EGD vapour being removed from the chamber. The EGD is sprayed at 28 into the chamber 2 as a mixture of droplets and vapour, but alternatively is supplied as a liquid which is evaporated in the chamber 2 by preheating it or by heating the chamber walls. Operation.-The material 1 is introduced into the chamber 2, and the valve 3 opened and exhauster 24 started to create a vacuum of 2 mm. Hg after which a two stage exhauster 23 also operates to create the same pressure as in EGD reservoir 21 which is continuously exhausted at 22. The valves 4, 6 are opened and pump 26 operated to introduce some liquid EGD from reservoir 21 into the chamber 2, the EGD being filtered at 31 and heated at 27 to between 60 and 70 C. Valves 4 and 6 are closed, and valves 7 and 8 are opened to supply liquid EGD from a separator 34 via heater 27 to sprays 28. The EGD vapour is drawn continuously from the chamber 2 by the exhauster 24 only, via condenser 32 (10-20 C.) and condenser 29 (+3 C. to -5 C.). The condensate from condenser 32 is gravity-separated at 34, the EGD being passed through a float-controlled progressive valve 9 to the input side of the pump 26, and the water passing to a lock 37 whence it is removed periodically by valves 11-13. The temperature of the liquid EGD is increased to between 100 and 110C. in dependence on the decreasing water extraction rate. When water extraction ceases, the valves 7 and 8 are closed and valves 6, 17 opened so that the liquid EGD in the chamber 2 is pumped to the reservoir by pump 26. The pump 26 is then stopped and valves 4 and 6-17 closed, and the pressure in the chamber 2 drops to between 0À02-0À03 mm. Hg. Valve 3 is closed and the material is submerged in impregnating mineral oil under vaccum which is then released.

The stand off elements may taper downwardly, may be held in sockets in the lower surface of the closure, and may project a specified amount below the closure. Preferably the elements are spherical or diamond section rollers. The closure may be so configured that relief channels define a series of flat plateaus in which the nozzle outlets are located and from which the stand off elements are dependent. The nozzles are so located as to cause the cutting in a borehole bottom of a central hole and grooves concentric of this hole, the outermost groove being of larger diameter than the bit, Specifications 1328133 and 1328134 are referred to.
