Title: Improvements in and relating to seed-sowing attachments for use on tractor and horse ploughs
IPC: A01C7/18
Filed: 1937-12-13
Abstract: 506,772. Distributers for seeds. HIGGINS, G. W. R. Dec. 13, 1937, No. 34425. [Class 6 (i)] A seed sower is provided with a guard or shield which is placed below the discharge orifice and forms a shoot for guiding the seed to the furrow. The front of the shield is curved to turn aside any soil piled up in front of the device. Fig. 1 shows a sower attached to a plough beam 5 and provided with a chain 6 attached to an arm 7 fast on the lifting shaft 8. Rotation of the shaft 8 lifts the sower from the ground and arrests the discharge of seed. The guard or shield consists of a plate 15 having a turned-up forward part 22 forming an inclined channel into which seed is delivered from the hopper 1. The outer surface of the part 22 turns aside any obstructing soil. The rear part of the guard is formed as an apron 23 and the guard is attached to the sower by bolts passing through holes 17, 20. The sower is attached to the plough by an arm 2 which is pivoted at 3 to an arm 4 pivoted on the lower limb of a stirrup 10. The latter embraces the beam 5, and the upper end of the arm 4 abuts against the upper limb of the stirrup 10 and is clamped between the beam 5 and a plate 11. Pivoted on the upper limb of the stirrup is a cam or rocker 13 which can be rotated by a screw 12 thereby swinging the stirrup about its lower limb and raising or lowering the lower end of the arm 4.

Title: Improvements in spinnerets and methods of producing the same
IPC: D01D4/02
Filed: 1937-12-15
Abstract: 502,926. Making cup-shaped shells for spinnerets. AMERICAN VISCOSE CORPORATION. Dec. 15, 1937, No. 34739. Convention date, Jan. 7. [Class 83 (ii)] [Also in Group IV] The metallic shell of a spinneret to be used in the production of artificial silk or the like comprises a flanged cup-shaped piece of noble metal having a face constituted by the bottom 'of the cup for perforation to permit spinning solution to be extruded therethrough, and a side-wall thinner than the flange and face and integral therewith. It may be produced by first forming a cup-shape by a pressing operation and then thinning the side wall by a swaging or spinning operation or by turning down on a lathe. Swaging or spinning hardens the metal so that the thinner side wall is of increased strength to compensate for the reduced thickness. As shown in Fig. 1, a plate of noble metal of uniform thickness is formed into a cup with a base 14, annular flange 16, and side wall 15. The length of wall 15 is less than the depth required in the finished cup. The wall 15 is then submitted to swaging whereby it is reduced in thickness but increased in length as shown in dotted lines. The finished shell as shown in Fig. 2, has the side wall 5 thinner than the base 4 or flange 6. The flange is annularly corrugated. The base 4 is finally bored to provide the extrusion orifices. Reduction in thickness of the side wall by swaging may be effected in one or more stages. The metal is preferably of fine grain structure. As shown in Fig. 3, the spinneret shell on a mandrel 17 is placed in a swaging machine comprising a revolving disc 7 with a slot 8 and slidably mounted swaging dies 9. These dies are held between backers 10 wth projecting rounded ends. As the disc rotates the dies and backers pass between pairs of rolls 13 which force the dies 9 together. The rack 12 with rolls 13 rotates slowly in order to distribute evenly the effect of the dies. The spinneret shell may be of gold or platinum or a gold-platinum alloy.

The metal tape covering the cable terminates at the point 3 while a shield 22 of tape contacting with the sleeve 7 is wound on the base of a built-up structure 21 of insulating tape at the upper end of which are barrier tubes 23. These structures distribute the electrostatic strains in the oil &c.

[Class 97 (i).] Comprises an arrangement for testing the working of optical sound-reproducing apparatus. A perforated disc 5 is so disposed that its toothed periphery runs in the path of the light rays passing through a slit 1 to a photo-electric cell 4. The disc 5 is rotated by a motor 6 at a speed such that the interruptions of the light beam correspond to the frequency of a definite musical note so that the loud-speaker 9 reproduces a corresponding tone. The starting of the motor is controlled by a contact device 7 which is closed when the sound-record film 3 has run out of the reproducing apparatus. A relay 8 can be operated simultaneously with the starting of the motor to cut out the loud-speaker 9, when the test can be carried out by observation of a measuring instrument 11. In order that the disc 5 shall stop on a position in which the light rays are free to pass when another film is passing through the apparatus, a magnetic stop 12 is provided, or mechanical means may be utilized for this purpose.

In a method of making a semi-conductor device comprising partially diffusing a body of activator material characteristic of one conductivity type into a surface of a larger semiconductor body of the opposite conductivity type to form a PN junction, the activator body is deformed during the melting, causing the diffusion by a contacting member of good heatconducting metal wettable by the activator material with respect to the shape it would have assumed in the absence of the member, whereby the shape of the junction formed is a mirror image of the deformed shape of the surface of the activator element and whereby the member provides a terminal for the device. In the Fig. 3 embodiment discs 10, 12 of activator metal are pressed by metal contacting members 18, 25 against surface regions of Ge wafer 2 which are free from the heat resistant and chemically inert film 4, e.g. of evaporated silica, covering the remainder of the surfaces, the pressure being limited by mica spacers 6, 8. The assembly is heated at 500‹ C. for 10 minutes to diffuse the activator material into the wafer to form parallel PN junctions therein, and to fuse it to members 18, 25. Electrode 16 is simultaneously ohmically connected to the wafer by a blob of tin or solder. Members 18, 25 are provided with tapped holes 28, 30 by means of which metal cooling fins may be attached and the device is encased in plastic 26. One of the members may be a metal cup into which the other elements fit, the other elongated member and ohmic connection being positioned by a lid during the heating. The lid may then be retained or removed and the cup filled with plastic material. A layer of gold is used between each contacting member and its associated activator body to prevent diffusion into the Ge from the members. In a further embodiment (Fig. 6) metal contacting members 48, 50 are provided with curved parallel parts where they contact the activator so as to provide curved parallel junctions.
