Title: Improvements relating to the rectification of alternating current supplies
IPC: H02M7/06
Filed: 1957-05-27
Abstract: 862,724. Rectifiers. KRIMHOLTZ, J. May 23, 1958 [May 27, 1957], No. 16740/57. Class 38 (2). A rectifying system whose output voltage remains substantially constant with changes in input voltage and output current comprises a saturable main transformer T3 which has a capacitor C1 connected across its primary winding, and supplies a rectifier bridge R2, and two auxiliary transformers T1, T2. The relatively small voltage from the secondary winding of transformer T1, which is connected in series opposing with the secondary winding of transformer T3, compensates for the changes with supply voltage of the voltage output transformer T3. The voltage output of transformer T2, which is rectified at R1 and added to the output voltage of rectifier R2 compensates for the impedance drop as the load current rises, because the current in its primary winding, which is connected in series with the primary winding of transformer T3 across the primary winding of transformer T1, increases with the load current.

Title: Improvements in or relating to fog warning apparatus
Inventor: CHAPMAN LESLIE WILLIAM
IPC: B64D45/00
Filed: 1953-06-17
Abstract: 735,808. Anemometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 17, 1954 [June 17, 1953], No. 16767/53. Class 69 (1). [Also in Groups XXXV and XXXVIII] In fog warning apparatus (see Group XXXVIII) an anemometer is used to close electric contacts when the wind velocity falls below a predetermined value. Supported by a pedestal 3 is a column 5 carrying at its upper end a pillar 6 of insulating material on which a nut 6a secures a dome 7 of a bell. The pillar 6 has a central bore accommodating an anemometer spindle 8 carrying a set of vanes 9, only two of which are shown. The foot of the spindle 8 is pointed and rests in a conical recess in a bearing block 12. Fitted around the top of spindle 8 between the hub thereof and the nut 6a is a coiled spring 31 tending to oppose rotation of the anemometer under wind pressure. The pillar 6 is slotted at 32 and a bar 33 (screwed into spindle 8) extends through the slot 32 which is sufficiently wide to permit slight movement of the bar and thus slight rotation of spindle 8. Arranged on the base of pillar 6 is a spring set comprising contact-carrying members 34 and 35 which are side by side the member 34 having a lateral extension at its top to bring its contact opposite to the contact of member 35. The normal state of the spring set 34, 35 is closed but it is opened by pressure of the bar 33 against member 34. Thus the contacts are open while the wind velocity overcomes the action of spring 31 but close if the wind drops below this predetermined velocity.

Patent GB-629972-A (GB)
Title: Improvements in and relating to the production of articles from metal powders
IPC: C22C33/02
Filed: 1947-06-26
Abstract: An article is produced from ferrous powder by the known method of compacting under pressure and sintering, and chromium is diffused into the surface layers after the completion of the sintering process, thereby producing a stain resisting-surface with properties similar to stainless steel.  The ferrous powder may be mixed with other powders such as copper, nickel, manganese, tungsten, titanium, molybdenum, columbium to give any special properties required.  The diffusion of chromium is effected by a gaseous halogen of chromium, at a temperature of 1050 DEG  C, the sintering of the compact having been carried out at a higher temperature of from 1100-1400 DEG C so that sintering is completed before the interdiffusion process takes place.
