Patent GB-725234-A (GB)
Title: Winding head for stator coil winding machines
IPC: H02K15/06
Filed: 1953-06-25
Abstract: 725,234. Coil making apparatus. COMPAGNIE ELECTRO-MECANIQUE. June 25, 1953 [Nov. 7, 1952], No. 17680/53. Class 35. A winding machine for winding stators of different diameters and lengths from slotted dummy rotors from which windings are radially pushed into corresponding stator slots comprises a body consisting of three members 13, 19, 20, a central shaft 22 slidably mounted in the body, telescopically arranged tubes 25-28 slidably mounted on the end of the shaft 22, a coil head forming comb 29 also slidably mounted on the end of the shaft 22, a camshaft 23 slidably mounted in the body and linked with the shaft 22 by a member 24, a guide member 30 arranged to move the tubes 25-28 and the comb 29, and a locking device 31 which is fast with the guide member 30 and which holds the tubes 25-28 in interlocked relative position so that these tubes travel in the same direction as long as they are engaged by the device 31. The winding machine is hydraulically controlled. When fluid pressure is applied to a piston 14 of the shaft 22, the latter moves axially and carries along the linked camshaft 23. This camshaft has a toothed segment 17 which enables it to rotate about its axis under the impulse of a toothed rack 38 which is in turn actuated by a piston 39. Two pistons 15, 16 actuate the guide member 30 which supports the tubes 25-28, the comb 29, the locking device 31 and lock springs 32a, 32b and the return screw 37. The pistons 15, 16 move the guide member 30 in the same direction as the previously actuated shaft 22 and, as the guide member 30 moves the locking device 31, the tubes 25-28 travel in this direction as long as they are engaged by this device; thus as this device clears the first step 33 of the camshaft, the springs 32a, 32b will cause this device to release the innermost tube 28. The successive steps 34, 35, 36 of the camshaft will thus progressively release the remaining tubes 27, 26, 25 respectively. The extent of the comb travel is controlled according to the requirements of the stator which is to receive the windings. To reverse the above mentioned movements it is necessary to apply fluid pressure to the opposite side of the pistons. For winding stators of same diameters but different lengths, the dummy rotors have a spindle 8 of constant length, Fig. 1 (not shown), and for winding stators of different bores either the thickness or the number of the tubes 25, 28 or, both thickness and number is altered as required. Specifications 639,069, and 649,432 are referred to.

Title: A process for sterilising and oligo-dynamically activating substances
IPC: A61L2/238
Filed: 1928-06-20
Abstract: 293,385. Krause, G. A. July 5, 1927, [Convention date]. Disinfecting; toxins; medicines for internal use; medicaments for external application.- Solids, liquids, and gases are sterilized and oligodynamically activated by contacting them in the presence of a liquid with oligodynamic ally active metals or alloys, particularly silver or copper or their alloys, the metals or alloys being in a non- colloidal form having a large surface area with a finely lamellated or finely sealed structure. Silver may be prepared in the desired form by carefully heating the tartrate or nitrate and finally gently igniting. The metals may be used in making sterilizing apparatus such as vessels, flasks, tubes, &c. The metals can impart their active properties to substances treated, e.g. a treated liquid may be used to sterilize, an untreated liquid. Treated water can be used for sterilizing air by washing, or by introducing it in mist or spray form into the air. The treated water may be used in preserving foodstuffs, such as meat and vegetables, or plant extracts and other technical preparations. The Specification as open to inspection under Sect. 91 (3) (a) comprises the use of cadmium and palladium as oligodynamic metals. The metals may be deposited on asbestos, clay or other carriers of regular or irregular shape, e.g. by impregnating the carriers with the metal gels or with silver nitrate and then igniting. The carriers may have a chemical or physical action, e.g. oxidizing or absorbent, on the substance treated Solids may be treated with powders or suspensions of the metals which may afterwards he recovered by suction or washing followed by filtration or centrifuging. The. metals may be employed, if desired, on carriers or in powder form, as internal or external medicines. The action of tetanus, diphtheria and other toxins on the animal cell is weakened by means of the metals. The action of the metals may be aided by employing heating and cooling devices, by passing an electric current, by exposure to rays, and by imparting an intermittent or continuous motion to the, substances, e.g. by a stirrer, or a pump or other device for introducing a blast of air or other gas or vapour. This subject-matter does not appear in the Specification as accepted.
