Title: Method for increasing the output energy of a power laser
IPC: H01S3/23
Filed: 1971-04-19
Abstract: 1327672 Lasers COMMISSARIAT A L'ENERGIE ATOMIQUE 19 April 1971 [6 Feb 1970] 20329/71 Heading H1C The output beam of a laser generator is passed through a pupil 2 and a converging lens system 9 so placed that the beam diverges as it passes through subsequent amplifying media 3, 4 and 5. The pupil 2 may be an apertured resonator mirror, and solid, liquid or gaseous active media may be used. The various lengths shown on the Figure are chosen to produce an image B of the pupil at the centre of the amplifying media. The diverging beam prevents fracture or damage of the amplifiers, and the ratio of L : I in the Figure is large to prevent Fresnel rings which result from diffraction around the pupil from causing non-uniformities in the beam. This allows the amplifiers to be operated close to the fracture limit. The area around the focus F of the lens system may be evacuated to prevent any breakdown. A single amplifier may be used.

Title: Improvements relating to hoisting plant for collieries and the like
IPC: B66B1/12
Filed: 1923-08-14
Abstract: 217,091. Brown, D. F., Raymer, F. J., and Westinghouse Brake & Saxby Signal Co., Ltd. Aug. 14, 1923. Regulating and control-transmitting gear; signalling and indicating apparatus.-The decking- levers for controlling the charging and winding of a mine cage when conveying tubs, are interlocked with a third lever for use when winding men. While the operation of winding tubs is controlled automatically or semi-automatically through the decking-levers, the winding of men is controlled entirely from the engine room, and the winding operation is not commenced until separate signals have been received from the banksman at the top of the shaft and the onsetter at the bottom. In the present arrangement the winding operation also is deferred until additional visual signals are received in the engine room indicating that the decking-levers at both the top and bottom of the shaft are locked in their " off " position. As illustrated, the decking-levers 1. 2 and the third lever 6 are all pivoted on a common shaft and normally are all in their " off " positions. Movement of either of the levers 1, 2 to its " on " position to operate switch mechanism to handle tubs, causes tappets 7 to engage recesses 10 in the lever 6, thus locking the latter in its inoperative position. On the other hand, movement of the lever 6, to operate the visual signal in the engine room for winding men, displaces the tappets to engage recesses 9, thus locking both decking-levers in theirinoperative position. A similar set of mechanism is provided at both the top and bottom of the shaft. To prevent accidents in the changeover to winding tubs after winding men, the third lever may be provided with an electric locking- mechanism which holds it in the " on " position until such time as the cage is properly positioned at the bank and is supported on the keps.

Abstract: 1493994 Winding insulation for elastic machines N I I EXPERIMENTAL INST AVTOMOBIL ELEKTROOBORUD I AVTOPRIB 20 May 1975 21403/75 Heading B3A [Also in Division H2]  Insulation for the windings of an electric machine is in the form of a sleeve 1, of S-shaped cross-section, having a portion 4 covering the slot conductors and a portion 3 covering the endconnectors, there being a transverse notch extending for half the depth of the sleeve at the point where the slot portion joins the end connector portion. This allows a portion 6 of the sleeve to be best for use as interlayer insulation of the end connectors while a portion 7 is used as interturn insulation of the bottom layer of end connectors. The sleeve is formed, cut and placed in the armature 15 as follows. A motor 20 drives through crank gear 23 reciprocating rod 8 which has various cams for driving the mechanisms. Cam 9, Fig. 3, drives an arm 54 which drives ratchet-and-pawl 25, 26 which drive four pairs of rollers 24. Rollers 24 drive insulating tape 14 shaping it into an S-shaped sleeve. After rollers 24, tape 14 penetrates a slot (29), Fig. 5 (not shown) in die 28 where it is simultaneously cut off into a length suitable for one turn of the winding and the notch is cut. This is done by cam (39) on rod 8 tilting lever (40) to pivot latch (38) so that punch (31) carrying knives (32, 33) is urged down by spring (34). During the reciprocal stroke of rod 8, cam (37) on rod 8 restores punch (31) ready for the next stroke. When rollers 24 push in the next portion of sleeve the original portion is pushed into an armature slot. Cam 11 on rod 8 moves lever 51 which through pawl 52 and ratchet wheel 48 actuates a microswitch 50 to count the number of slots and also cam 43 on rod 8 through pawl 42 rotates armature 15 one pitch.
