Filed: 1953-09-29
Abstract: 735,608. Making butter. ZEUTHEN, C. Sept. 29, 1953, No. 26698/53. Class 84. Butter is made by first churning cream in a closed rotating stainless steel drum provided with beaters, then introducing through an opening in one end bottom mechanically moved kneading rollers, finally removing the rollers, closing the opening and continuing kneading (by the beaters) under a vacuum. The apparatus comprises a drum with interior beaters 4, an opening therein closed by a detachable cover 9 in a bearing 10 on a pivotable arm 11 on a post 12. Vacuum is applied through pipes 15 and 13 connected to the bearing 10. Kneading is by rollers 18 on a travelling carriage 16 and the churn and rollers are, by suitable connections, driven from gearing 1. Cream is prevented from reaching the bearing by means of an adjustable valve body (Fig. 4, not shown).

Title: Improvements in or relating to methods of sealing a metal contact element into a glass wall
Inventor: BREADNER ROBERT LEONARD
IPC: H01J5/62
Filed: 1954-09-21
Abstract: 773,226. Glass-metal seals. GENERAL ELECTRIC CO., Ltd. Sept. 5, 1955 [Sept. 21, 1954], No. 27302/54. Class 36. In sealing a button contact 1 to a glass wall 4, the contact is first sealed to one end of a glass collar 3, the opposite end of the collar is placed against the wall 4 which is softened by heat, the contact and collar are pushed axially into the softened wall to form a closed chamber within the collar in which a gas pressure is created so as to cause the softened glass of the wall to bulge away from the contact and eventually blow out and form an aperture in the wall, the movement of the contact and collar being arrested when the former reaches the position in which it is to be sealed, and the contact, collar and softened glass surrounding the aperture are heated to cause the glass to flow over the outside of the contact and form a seal. The contact 1 is mounted, with the collar 3 uppermost, on a support 5 having a spigot 6 fitting within the contact. The spigot is mounted on a base 7 carried by a rod 8 which is slidable but not rotatable in a mounting 14. The support is biased upwardly by a spring 15, upward movement being limited by stop 16. A circular rim projects above but is spaced from the base 7, the lower edge of the annular gap 19 communicating with a number of ducts 18 radiating from duct 20. A rotating gas burner is arranged above the wall 4 so that a circular zone of glass surrounding an indentation 11 in the wall 4 is heated whilst the collar 3 is pressed against the wall by the-spring 15. The air trapped within the collar, or gas given off from a decomposable substance provided therein, expands, forming an upward bulge in the part of the wall covering the end of the collar. The stop 16 arrests upward movement of the support when rim 17 is just pressed into the softened wall 4. After the bulge has burst, a vacuum is created in the chamber between the base 7 and wall 4, causing the softened glass to be drawn down towards the base and moulded to the shape of the base and the rim 17 (Fig. 5). The mounting carrying the spigot 6 is then withdrawn from the contact and the glass annealed. Instead of being formed with a central aperture, the contact may be of the type provided with a central stud and the spigot 6 is then shaped to fit over the stud and closely adjacent the inner conical surface of the contact.
