Abstract: 292,510. Skip-Cie Akt.-Ges., and Roeren, C. June 20. 1927, [Conventiondate]. Skips.-In a bottom-discharge skip a for mine shafts, the bottom of the skip is formed by an inclined face b and an inclined door c pivoted at its lower end at d to act as a discharge shoot. and the door c is connected at its upper end to the body of the skip by a link and a radius rod. When the door is closed the joint between the link and the radius rod passes beyond the dead centre locking the door in the closed position. As the door opens, material begins to move downwards before the commencement of discharge. The door c may comprise surfaces b<1>, b<2>, c<1>, c<2>, of different inclination, as shown in Fig. 4, or it may be curved so that the front edge of the discharge opening may be raised without reducing the capacity of the skip.

Mechanism for scanning a record track by moving a sound head in successive reverse transverse directions across a record being advanced step-by-step, comprises a driving member adapted to move to and fro in a fluid chamber characterized in that said member consists of a vane fast with a shaft and oscillating in said chamber, at least one end of the vane being provided with an armature of magnetic material oscillated in opposite directions by magnetic means. In its simplest form, Fig. 1, a shaft 1 carrying the transducer is provided with a vane 2 oscillated in a fluid chamber 3 by means of a curved armature 5 acted on by the poles 11, 12, 13 of an electromagnet having coils 7, 8 which are alternately energized to produce the appropriate oscillation. In another embodiment, Figs. 4 and 5, the armature is in the form of a small plate 45 moving between the poles of ring magnets 46, 48. A third embodiment, Fig. 6, is in substance a duplex edition of the first embodiment, the essential differences being that baffle plates 68, 69 are provided to effect damping of the fluid flow in the chamber, and six coils are provided to produce two sets of three poles equivalent to the poles 11, 12 and 13 of the magnet in Fig. 1. It will te seen by the circuit diagram of Fig. 9 that each time the reversing switch 116 is operated to one position or the other, the current in the centre poles is reversed while remaining uni-directional in the side poles. The side poles may, therefore, be permanent magnets. The movable member of the reversing switch may be actuated by the oscillating shaft, but arranging contacts,as in Fig. 8 (not shown). Specifications 789,195 and 792,435 are referred to.

Title: Improvements in or relating to the manufacture of sheets from a reel of paper
IPC: B65H35/06
Filed: 1961-05-17
Abstract: 950,654. Cutting-apparatus. J. E. THOMPSON. Aug. 14, 1962 [May 17, 1961], No. 18019/61. Heading B4B. [Also in Division B6] A method of manufacturing sheets of paper from a reel of paper which is wider than the sheets comprises the steps of unwinding the reel, slitting the paper as it is unwound from the reel at least once to form a strip of the desired width, re-reeling the remainder of the paper, passing the cut strip to a cutting device where the strip is cut into desired lengths, and transferring the lengths for subsequent use, the leading edge of the strip being supported during the cutting and transferring operations. As shown, paper unwound from a reel 1 is cut by a rotary slitter 5 into a strip for feeding into checking and sorting apparatus 2. The slit strip is then arranged to pass over a guide roller 6 and below a loop forming device 7 to a cutting device while the remainder of the paper is rereeled on a reel 8. The cutting device comprises a die 12 reciprocable in the direction of travel of the paper strip, the face of the die arranged to contact the strip being provided with one or more countersunk suckers 15. A knife 16 is reciprocable in the direction of travel of the strip but is also movable normal to the direction of travel of the strip. Two movable sucker arms 17, 18 each carrying one or more suckers 19, 20, respectively, are reciprocable from a position adjacent the knife 16 to a position where they can transfer the cut paper sheet into grippers 3 of the apparatus 2, the grippers being carried on endless chains 4. The arrangement is such that the leading edge of the strip is supported either by the suckers 15 or by one or other of the sucker arms 17, 18, while the leading edge of the cut sheet is also supported by one or other of the sucker arms. When the reel 1 is exhausted, the reel 8 may then be moved along a width equal to that of the cut strip whereupon the paper from the reel may be fed past a rotary slitter 9 to form a strip to be fed to the apparatus 2, the remainder of the paper being re-reeled on the reel 1. Alternatively, a plurality of rotary slitters may be provided in line above the reel so that during the unreeling thereof the paper is divided into strips each of a width for feeding into the apparatus 2, one strip being fed to the apparatus while the remainder are re-reeled for subsequent feeding. The knife 16 and die 12 may be replaced by a rotary knife. Instead of feeding the cut sheets directly into the grippers 3, they may be fed into a further sucker mechanism arranged to feed into the grippers. Alternatively, the sheets may be fed into any other apparatus or even into piles. Specification 950,653 is referred to.

For use with screw-plug fuses, the replaceable member is a screw socket 20, Fig. 1, which is attached by screws to the strip 15, and by the nut in the recess 17, whilst for use with two-pin fuses the replaceable members are a plate 23, Fig. 3, carrying a socket 24, and a second socket 27 screwed into the strip 6. The distance apart of the sockets 24, 27 may be increased to accommodate a larger fuse by turning over the plate 23.

Title: Improvements in or relating to multistable laser devices
IPC: H01S5/32
Filed: 1965-04-30
Abstract: 1,071,434. Semi-conductor laser devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 30, 1965 [May 13, 1964], No. 18240/65. Headings H1C and H1K. An injection laser is positioned contiguous with an absorber of the output of the laser such that when the energy absorbed by the absorber is reduced an increased quantity of energy is reflected back into the laser to cause the latter to emit coherent radiation. In the arrangement of Fig. 2A a gallium arsenide PN junction crystal 6 with cleaved ends 10, 11 is divided into two electrically isolated portions 12, 13 by slot 14, section 12 being biased by battery 23 to act as a light emitter below the threshold for lasing action and section 13 being biased by 23<SP>1</SP> to act as a light absorber. When the laser injection current is first turned on light passing into the absorber is absorbed forming a new electron hole pair which on recombination emits light in random directions. In this condition of the device the effective reflectivity of the absorber is low, Fig. 1B (not shown), and there is a high laser threshold. When a current from generator 26 is applied to contact 20, or a current pulse applied from generator 26<SP>1</SP> or if an external pulse of light enters the absorber or an external pulse of light travels from the laser to the absorber then the absorbtion of light in region 13 decreases and the effective reflectivity of the device increases. This causes a lowering of the laser threshold and simulated emission occurs which maintains itself after the current pulses or external light pulses terminate. The device is turned to its off state i.e. emitting spontaneous non-coherent light, by a negative trigger pulse from generator 26 or 26<SP>1</SP> or by an external light pulse travelling transversely through the laser 12. In the arrangement of Figs. 3A, 3B (not shown), a second non-linear absorber is added to the basic configuration shown in Fig. 2A transverse to the first absorber. This arrangement is tri-stable in so far as there are two on states when either of the absorbers are bleached and a coherent output is produced and an off state corresponding to high attenuation by the absorbers when there is no coherent output. The three portions may be cut from the same semi-conductor wafer.
