Abstract: 522,203. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 1, 1938, No. 35028. Convention date, Dec. 1, 1937. [Class 38 (iii)] The field contactor 6 of a synchronous motor 1 is under the control of a relay 10 energized in accordance with armature current pulsations, and. effective, when the motor speed reaches a predetermined value, to open contacts 17 for a sufficient interval to enable a relay 19 to close its contacts 32 by which the contactor 6 is controlled. A unidirectional current conducting device 24 is included in the closed field circuit so that alternate impulses of armature current are different, and the relay 10, therefore, always operates at a predetermined point in the cycle of slip current The setting of the relay 10 is adjusted by operation of the contactor 6, and effects disconnection of the field by opening contact 25 when the motor falls out of synchronism.

Abstract: 1282367 Device for holding a workpiece WERKZEUGMASCHINENFABRIK OERLIKONBUHRLE A G 21 July 1970 [23 July 1969] 35208/70 Heading C7N A device for holding a workpiece 8 or 9 having a tubular portion during quenching is mounted between a ram 43 and a bed 1 of a press. A centring die 6 projects into the central bore 5 of the bed 1, the upper part of which is of slightly smaller diameter than the workpiece 8 or 9. The spring ring 19 encircles the segments into which die 6 is divided. The workpiece is gripped on the inside by the die when the plunger 23 enters the divergent bore 10 and expands the die 6. The workpiece is gripped from the outside by a clamping bell 49, the wall of which is divided into fingers 50, convexly shaped on their inner and outer surfaces. An adapter 45 engages the outer surfaces of the fingers and applies a force radially inwards so that the fingers grip the workpiece, as the ram 43 is lowered until the fingers touch the supporting ring 56. At the same time, centring ring 35 is expanded by the truncated cone 40 of the holder 29, so that it grips the workpiece on the inside at the same level as fingers 50 grip it on the outside. The workpiece can then be quenched in oil which enters through bores 11 in die 6 and passes out through gaps between the fingers 50.

Title: Improvements in or relating to apparatus for inserting eyelets in labels or the like
IPC: A43D100/02
Filed: 1922-12-29
Abstract: 204,254. Lux, E. Dec. 29, 1922. Setting eyelets.-A machine for inserting eyelets in labels, advertising sheets, documents, leather, fabric, &c., of the kind in which the eyelets are fed to the work automatically and set by the operation of a hand lever, has the eyelet reservoir formed in, or in an extension of, this hand lever 5, which is provided with a removable cap 10 for the purpose of refilling it. Cheek plates 6 of the lever 5 are pivoted at 4 to the frame of the machine, which comprises two standards 1 connected by a bedplate 2 and cross-bar 3. Eyelets, feeding.-As the operating lever 5 is oscillated about its pivot 4 during working of the machine, the eyelets in the reservoir are shaken to pass in proper position only into a delivery raceway 8, Figs. 4, 6, formed by sideplates having obliquely-arranged openings 7 and a cover plate 32. When the handle is inclined above the horizontal, the eyelets pass along to a gutter 9 in the handle, the leading one being gripped by spring tongues 14. In order to prevent the eyelets in the gutter 9 running back into the lever 5 when this lever is depressed below the horizontal, the passage from the raceway 8 to the gutter 9 is stepped. A catch pin 21 is frictionally held in a set piston 17, pivotally mounted about a pin 16 on extensions 15 of the cheek plates 6, this pin being cross-bored to guide the catch pin 21, so that, as the handle 5 is depressed, the end of the catch pin 21 is forced upwards by contact with a guide surface 22 bearing against the cross-bar 3 to engage the leading eyelet. Further depression of the handle causes the eyelet to be moved into the position shown in Fig. 3, a guide pin 20 on the piston 17 moving along a guide surface 23, 24 on the frame of the machine to effect this. Setting-mechanism.-In this position with the eyelet centrally above the pivot 16 cf the set piston 17, the eyelet is flanged over the work between the piston and a die 25, the centring pin 26 of which pushes the catch pin 21 back into the set piston. After flanging, the parts of the machine are restored into the position of rest by the combined actions of springs 30 and 18, the guide surface 22 being pushed downwards against the action of a spring 28 by the end of the catch pin in its return journey to the position of rest.

Title: Process for the production of metals and alloys, with very small contents of carbon
IPC: C21C7/00
Filed: 1933-12-16
Abstract: In a process for producing metals and alloys very low in carbon, for example chromium, manganese, and their iron and steel alloys, by the direct reduction of the ore with a silicon-containing reducing agent in a molten main metal both low in carbon, the charge used comprises ore, limestone, and reducing agent, which have been preliminarily heated at 1000-1100 DEG  C., in a strongly oxidizing flame until the combustion of carbon is complete and the limestone is converted into caustic lime.  The charge after grinding and thorough mixing is loaded in a layer over a continuously rotating heating platform.  The treated charge is discharged into closed iron boxes for cooling and storage.  If the combustion gases are to be circulated for further use, they are purified in respect of carbon dioxide, and sulphur, for example by caustic potash.
