Abstract: 840,355. Autographic registers. LAMSON PARAGON Ltd. Sept. 16, 1958 [Sept. 16, 1957], No. 29137/57. Class 16. In an autographic register wherein stationery webs are fed by rotary friction feed discs operated by means of an oscillatable handle, the successive form lengths of the webs are fed in two stages, the first being effected by the forward stroke of the handle, and the second on the return stroke of the handle. As shown, two feed discs 7, on a non-circular shaft 4 mounted in bearings in the casing 6, co-operate with feed rollers 8 on a shaft 8a to feed the webs. The handle 3, oscillatable about a stud 18, carries a gear quadrant 17 in mesh with a gear 13 on a clutch member 11 which is rotatably mounted a sleeve 10 forming part of a cooperating clutch member 9 secured to the shaft 4. A spring-urged dog 14 on the member 11 is adapted to engage a shoulder 15 in the member 9 to constitute a one-way clutch for driving the shaft 4 only in a clockwise direction, Fig. 4. The shaft 8 has a gear 28 meshing with teeth 27 on the clutch member 9. The outer face of the quadrant 17 has a feed lug 21 combined with a locating lug 23 at one end, and a stop lug 22 at the other end. The outer face of the member 9 is recessed at 24 to provide a camshaped portion 24a for engagement by the feed lug 21, and recesses 25, 26 on the inner face of the member 9 co-operate respectively, with the locating lug 23 and the stop lug 22. On counterclockwise rotation of the handle 3 and quadrant 17, Fig. 4, the shaft 4 is rotated clockwise to feed the stationery webs during the first feed stage which is terminated when the stop lug 22 enters the recess 26 in member 9. When the handle 3 is released, it is swung backwardly in a clockwise direction by a coil spring 30, the member 9 not being driven owing to the oneway drive in the clutch. However, just before the handle and quadrant complete their return movement, the feed lug 21 enters the recess 24 to engage the cam portion 24a, Fig. 4, and imports a small clockwise rotational movement to the member 9 to cause the feed discs 7 to feed the stationery webs a second time to complete the feeding of a form length over the writing plate. The extent of the second feed is limited by the engagement of the locating lug 23 in the recess 25. During the first movement of the quadrant 17 means, such as a pawl engaging an arcuate track on the quadrant, may be provided to prevent reverse movement thereof.

Title: Xylostasin derivatives and the production thereof
IPC: C12R1/185
Filed: 1974-07-02
Abstract: 1481019 Xylostasin phosphates TAKEDA YAKUHIN KOGYO KK 2 July 1974 [9 July 1973] 29263/74 Heading C2P The invention comprises the 3<SP>1</SP>-, 5<SP>11</SP>-, and 3<SP>1</SP>,5<SP>11</SP>-diphosphate of xylostasin which has the formula and a salt, especially a physiologically tolerable salt thereof. The phosphates may be obtained by contacting xylostasin in a solvent or diluent and in the presence of a phosphate donor with cells of or cell material derived from a microorganism which belongs to the genus Escherichia or Achromobacter and which is resistant to at least 100 Ág. xylostasin per ml. Specified microorganisms are Escherichia coli (ATCC 21990) and Achromobacter xylosoxydans (ATCC 31040) whose microbiological characteristics are described. The cells may be obtained by propagating the microorganism in a medium containing one or more carbon sources, one or more nitrogen sources and one or more inorganic salts and the cultivation may be performed by the stationary cultural method or by the aerobic stirring method and the disrupted cells or cell material may be obtained by subjecting the culture broth or the cell material isolated therefrom to a suitable physical or chemical treatment. In the phosphorylation the solvent or diluent may be water or the cellcontaining culture broth may be employed and the phosphorylation is preferably effected at 30‹ to 40‹ C. and at pH 6 to 10. The xylostasin phosphate ester products may be converted to a corresponding product wherein the phosphoric ester group is replaced by a halogen atom, i.e. to the corresponding halogenodeoxy- (or dihalogenodideoxy-) xylostasin and, if desired, the latter can then be reduced to form the corresponding deoxy- or dideoxyxylostasin which are useful antibiotics. The conversion of the phosphate to the halogenodeoxyxylostasin may be effected by protecting the free amino and hydroxy groups of the phosphate or diphosphate, e.g. by reaction with a silylating agent, e.g. hexamethyl disilazane, or an acylating agent, e.g. acetic anhydride, reacting the protected compound with a halogenation agent, e.g. trimethylsilyl chloride, and removing the protecting groups. Detailed examples are given for the production of xylostasin 3<SP>1</SP>-phosphate and xylostasin 5<SP>11</SP>-phosphate respectively and for the conversion of the 3<SP>1</SP>- phosphate to 3<SP>1</SP>-chloro-3<SP>1</SP>-deoxy-xylostasin and the reduction of the latter by means of a current of hydrogen gas in the presence of Raney nickel and triethylamine to form 3<SP>1</SP>- deoxy-xylostasin. Specification 1,460,039 is referred to.

Title: Improvements in or relating to traversing mechanisms for record playback arms of recording machines
IPC: G11B3/085
Filed: 1966-06-29
Abstract: 1,145,536. Recording and playback. ELECTROACUSTIC G.m.b.H. 29 June, 1966 [29 June, 1965], No. 29302/66. Heading G5R. A traversing mechanism for the record-playback arm carrying the transducing head of a dictating machine, of the type wherein the arm is pivoted reciprocally relative to a moving tape, operates so that the traversing arm is driven at uniform speed in either of the pivotal directions through two friction tracks arranged concentrically, one of which is engaged by one of a pair of cone pulleys on a drive pinion, only one pulley being in friction engagement at any one time. The ratio of the radius of one pulley to that of its related friction track is equal to that of the other pulley to its related track. The driving pinion is connected to a unidirectionally rotating motor through a friction gear. Three embodiments of the invention are described. In a first of these, the drive pinion is mounted on the arm carrying the transducing head and is belt driven via friction linkages from a motor mounted on the machine frame. The pulleys on the drive pinion run in a slot in a member aligned with the recording tape and which can be moved in the direction of the tape by a relay operated arrangement. The direction in which the member is moved determines which pulley is engaged by one of the opposite concentric edges of the slot, and consequently in which direction the head is rotated. In a second embodiment (Fig. 5) the slot is fashioned in a section 10a in the arm la supporting the transducer 2. The drive pinion and pulleys 6<SP>1</SP>, 6<SP>11</SP> are supported on an arm 51 pivoted relative to the machine frame at 40. The pinion is driven from a motor 27 by friction discs 49, 47, 48 and causes the arm to rotate as one friction pulley engages one of the faces of the slot. At the end of a traverse, one of the contact pairs 58, 59 are actuated to either energize or de-energize the relay 55 and consequently move the arm 51 so that the other pulley engages the other face of the slot. In a third embodiment the transducer arm is traversed by a cord which after passing round pulleys is wound up on a drum which incorporates a circular track in which the drive pulleys of the drive pinion operate. A relay controlled system can alter the position of the drum so that one or other pulleys engages one or other of the faces of the track.
