Abstract: 1,054,563. Letting off warps. WEBSTUHLBAU KARL-MARX-STADT VEB. April 6, 1964, No. 14128/64. Heading D1E. Warp is let off from a beam 1, with a brake drum 18, against the action of a ratchet operated, oppositely rotating band brake 17 that has its frictional force reduced as the warp beam diameter decreases. The band brake 17 is attached to and rotates with a worm-wheel 3 whose worm 12 is actuated by a ratchet 9, 10 operated, during the period between the opening of the shed and the beat-up, from a face cam 2 of the loom. The worm 12 may be actuated manually. The band 17 has one end 17a attached to the worm-wheel 3 and the other end to a bell crank 22 which is loaded by a spring 50 and a nut 47 mounted on a pivoted lever 45 which is moved by a nut 44 traversable along a screw 26 rotated by a ratchet 23 attached to the worm-wheel 3. Every rotation of the wheel 3 brings the pawl operating mechanism 43 of the ratchet 23 into the path of a pin 32. The position of the pin 32- is adjusted by a wedge 41 which is movable by the back rest 37 so that as the warp tension increases greater oscillation is given to the ratchet mechanism 43 to reduce the friction of the brake band 17. The initial friction may be adjusted by manually moving the other end of the lever 45. The back rest 37 is adjustably loaded by a spring 59 and may be locked in position during beat-up by the raising of a lever 68 having a brake shoe 66 operating on the linkage 39, 38 and 36 which adjusts the stroke of the ratchet 23.

Abstract: 1,084,039. Feeding capsules. N.V.W.H. VAN DEN TOORN'S INDUSTRIELE ONDERNEMINGEN CAPSULEFABRIEK " HOLLAND." May 20, 1966 [May 22, 1965], No. 22680/66. Heading B8S. A device for withdrawing a capsule 3 from a stack of capsules 2, which are inserted in each other and are laid in a tiltable gutter 1 with closed ends 4 directed downwards, comprises a gripper 6 mounted on a slide 7 and consisting of a cylindrical sleeve 18 with four spring fingers 20 each with a steel blade with a rubber gripper member 21. Around the sleeve 18 is mounted a second sleeve 22 in which the sleeve 18 can slide and a key 23 couples the sleeves 18, 22 for rotation in unison. The sleeve 22 is supported by a slide 19 attached to a driving- rod 13 continuously driven by an electric motor 11 via a coupling 12. The first capsule 3 of the stack of capsules 2 has its closed end 4 protruding through a resilient ring 5 with the exception of a few millimetres. The ring 5 comprises a number of segments 16, retained by a circular spring 17, and positioned in a housing such that they can move radially and also a little in the axial direction, which latter movement involves a small pivotal movement with respect to the spring 17, though this is not necessary for all sizes of capsule. Alternatively the ring 5 may consist of one integral part made of an elastic material. Fig. 5 shows the starting position in which the gripper members 21 are in their rest position corresponding to the outer surface of the capsule 3 in respect of its conical shape, length and diameter. When the slide 19 is moved to the right (as shown) both sleeves 18, 22 move to the right until the sleeve 18 is stopped by a fixed ejector 8 after which a spring 27 is compressed, the sleeve 22 slides over the sleeve 18 so that springs 25 press against the spring fingers so forcing the gripper members 21 to grip the capsule 3. In this position pawls 26 interlock the sleeves 18, 22, Fig. 6 (not shown). By means of a rotating mechanism, Figs. 8, 9 (not shown), both sleeves 18, 22 are rotated about their axis at the beginning of the retracting movement in which the capsule 3 is taken off and carried to the left. With further movement to the left, Fig. 7 (not shown), the ejector 8 engages the head of the gripped capsule 3 which then falls down and is ejected out of the gripper members 21 passing through a guide 9 and led thereby to the mouth 10 of a bottle 14 which arrives on a belt 15 stopped in a way known per se. Figs. 10 to 12 (not shown) illustrate a controlled retaining ring with segments (36) which grip the last-but-one capsule when the gripper members grip the last capsule 3. Retraction of the segments (36) allows the stack of capsules 2 to slide down until retained by a stop lever (50). The movement of the segments (36) can be made sufficiently large to accommodate large variations in the dimensions of the capsules.

Abstract: 1,228,342. String musical instruments. L. W. PAVIA, and C. FARNY, [trading as PAVIAFARNY ASSOCIATES]. 10 Jan., 1969, [4 March, 1968] No. 1547/69. Heading G5J. Each string 23 of a keyboard instrument is sounded by a pad 70 having a non-hardening adhesive layer 74 which normally rests on the string. When a key 50 is depressed, pad 70 and string 23 are raised until the tension in the string overcomes the adhesive force, whereupon the string vibrates to produce a tone similar to a harpsichord. Pad 70 possesses some resilience, and when lowered, dampens string 23. Pad 70 (Figs. 7A, 7B, 7C, 7D, 9, 10, not shown) comprises sponge rubber or polyfoam stiffened along its vertical edges with lacquer or glue, wood with a rubber layer # inch thick above the adhesive layer <SP>1</SP>/16-<SP>1</SP>/32 inch thick, or wood with a layer of a plastic material. In this last case, the string sinks into the material, and a damping vertical felt spigot (79) is attached at one edge of the pad. For high notes, adhesive may be applied to the string in a portion -<SP>3</SP>/ 8  inch long. A metal pin (84) may be positioned beneath string 23 and be connected to the pad by a rubber tube (83). When the pad is raised quickly, tube (83) snaps upwardly, and pin (84) strikes string 23, to give a secondary note. In all cases damping pads may be added to the strings. Keys 50 are pivoted at 55, biased to their normal position at 57, and limited in their movement by felt pads at 62, 64. The lugs are mounted on a board 51 which is screwed at each end to a base 13 of the instrument. A rod (20), (Fig. 8, not shown) is provided to rock the board 51, and hence lift all the pads 70 off strings 23, and thus equalize the adhesive power during subsequent use. One, two or three key manuals are provided. An enclosure beneath keys 50 contains tuning pins 25 to which the free ends of strings 23 are connected, the strings being doubled over a hitch bar (29), (Fig. 5, not shown) at the opposite end of the instrument. Bridges 69 and (27) are provided, one of which may be combined with hitch bar (29), and one of which may be used to electrically earth strings 23, so that pick-up coils (33) (Figs. 3A 3B, 4, not shown) may be used efficiently. There are twelve coils (33), connected in series and positioned along the strings for the desired harmonic content of the sound, and each extends over five strings except for a coil over the lowest six strings. Each coil (33) comprises twenty-five turns over a magnetic plastics cone with steel flux directing side-plates (36), and is fixed to the base 13 and above strings 23.

A light responsive circuit (for switching on the side lights of a car) comprises a resistance bridge WXYZ, one arm WX of which includes a photoresistor FR, on which light (ambient) impinges. A transistor Q 1  amplifies the signal appearing across the diagonal XZ of the bridge WXYZ and is connected to a switching transistor Q 2  which can be switched by the output of the first transistor, when the intensity of light is less than a predetermined value, and carry out a required control function (i.e. switching on the side light by means of relay R L  in the switching transistor's output). A positive feedback network consisting of resistor R 5  as shown ensures that once transistor Q 2  is switched on the light impinging on photo-resistor F R  must increase to above a second predetermined level before the current through Q 1  falls to the extent that Q 2  is cut off.
