Abstract: 1,241,229. Gas storage containers. BERNHABDT APPARATEBAU G.m.b.H. & CO. 9 Dec., 1968 [12 Dec., 1967; 7 Nov., 1968], No. 58361/68. Heading F4P. A device for inflating the floats of lifesaving equipment from a compressed gas container 6 having a frangible seal 7, the device comprising means (e.g. a needle 12, 52) for piercing the seal propelled by a striker pin 10, 92, using energy from a spring 13, 91 released by movement transversely with respect to the pin 10, 92, motion of a trigger member (e.g. a row of balls 19 or a pin 72 or a pin with a ball 19a, 19b at each end) resulting from axial displacement parallel to the pin motion of a spindle 21, 61 (e.g. due to another spring 27), this in turn resulting from a change in volume (e.g. by dissolving) of a body 26 due to the action of water (e.g. entering by passages 32), the spindle also having alternative means (e.g. pulling toggle 34) of displacement to release the energy of the spring 13. The device may be adaptable for manual use only by having an insert 25 reversible so that one end 37 is screwed into the body 1 and the cap 31 is screwed on to the other end 36, a protrusion 39 acting as an abutment for the spindle 21. In an alternative form, Fig. 8, the spring 91 is a torsion spring and is held by a ratchet end 97 on the trigger member engaging a ratchet wheel 96 on the pin 92 the released torsional spring energy being converted by a screw thread 101 to advance the pin 92. Methods of re-setting the device are also described.

Abstract: 1,255,613. Determination of hydroxyproline. ORGANON LABORATORIES Ltd. 10 Dec., 1968 [11 Dec., 1967], No. 58552/68. Heading B1X. A process for the determination of the hydroxyproline content of a biological fluid comprises treating a sample of the fluid with a strongly acidic cation exchange resin which adsorbs the free and peptide-bound hydroxyproline present, hydrolysing and adsorbed peptide-bound hydroxyproline by heating, eluting the hydroxyproline and determining its content in the eluate by means of a colour reaction. The resin is preferably a 2 to 10% cross-linked sulphonated polystyrene resin particle size 20 to 200 microns, optionally applied to inert carriers particles; others are mentioned. The eluate may be analysed by conversion of the hydroxyproline to a pyrrole compound using hydrogen peroxide or the Na salt of N-chloro p-toluene sulphonamide and formation of a colour by addition of p-dimethylamino benzaldehyde. A test pack comprises a bottle containing a strongly acidic cation exchange resin, at least two tubes for the adsorption and hydrolysis, at least one bottle containing a standard solution of hydroxyproline or a known quantity of hydroxyproline for the preparation of a standard solution, and bottles containing stable reagents for the performance of a colour reaction on hydroxyproline.

Title: Ribbon supporting and feeding mechanism
IPC: B41J33/04
Filed: 1971-12-17
Abstract: 1316533 Ribbon mechanisms INTERNATIONAL BUSINESS MACHINES CORP 17 Dec 1971 [30 Dec 1971] 58826/71 Heading B6F Error correction.-An adhesive erasing ribbon is used to lift an erroneous character from the paper in a typewriter. Ribbon tensioning.-A spring 93 acting against a cam 85 in the form of a multi-toothed ratchet 86, positively maintains a continuous force 90 in a direction opposing the direction of rotation 91 of the supply roll (21, Fig. 2), thereby maintaining a continuous tension on the ribbon. The tension maintaining mechanism and the ribbon supply roll are mounted on a platform 70 pivotally supported on the carriage frame (17, Fig. 2) by a stud 71, so that movement of the ribbon lift mechanism (60) is accompanied by tilting of the supply roll. The system includes a mechanism for selecting either of two spring rates for tensioning the ribbon to a lower tension if it is of the cover-up type and not the adhesive type. The ribbons are wound on different spools (Figs. 6 and 7) that provide for the automatic selection. Extensions (28) of splices (26) on the adhesive type spool engage in windows 88 on the multi-toothed ratchet 86 thereby trapping a control arm 101 against a stop 99. The spool without extensions (28) does not trap control arm 101, so that rotation of the supply-roll causes spring 93 to pivot counter clockwise about post 94. This pivoted movement is accommodated by stretching of light-spring 98 instead of flexing of the stiff spring wire 93. Take-up mechanism.-The ribbon is wound on a desposable spool (22, Fig. 2) driven by a toothed wheel (31) which engages the periphery under spring bias. The wheel is driven by a reciprocating pawl (38) engaging windows in the face of the wheel (Fig. 3). Specification 1,315,632 and 1,316,534 are referred to.

Title: Improvements in automatic typewriters
IPC: B41J25/02
Filed: 1968-12-12
Abstract: 1,256,248. Typewriters. ELECTRONIC ENG. CO. OF CALIFORNIA. 12 Dec., 1968 [26 Dec., 1967], No. 59053/68. Heading B6F. Power-operated type-lever machines.-The typewriter comprises a type-lever actuating mechanism 12 including a power-roll 15 and cams 50, and selective control means 10, 11 for operating the mechanism 12 in accordance with serially occurring signals, e.g. as sensed from a punched tape or incoming signals, the rate, at which the control means 10, 11 actuates the mechanism 12 when successive identical signals are received, e.g. two a's, two b's &c., being such that the corresponding type-lever 16 is reactuated while yet retaining a discernable part of the energy imparted to the type-lever during the previous print cycle and successive actuations of the same type-lever have a constant print quality. The line 77, 76, 80, Fig. 2A, represents the movement of a type-lever 16 from rest position 70, impact at 76, return to a rest position 71 and several rebound movements 72, 75 until the type-lever is quite still at the second reference 70 where a print cycle is complete and a repeat operation can be commenced. The time t between the points 71, 70 is wasted and in accordance with the invention the second action shown by the dotted line 77 in Fig. 2B is commenced at the point 70 or alternatively at selected other points (see Fig. 5, not shown) which are before the first action is completed. In this way the rebound force is used in the same direction as the force derived from the first power roll action and even impression results. Synchronization of the striking action from the power roll 15 and the selective control means 10, 11 is maintained by worm gears 32, 36 and pinions 35, 37. A belt drive couples the power roll to a pulley advancing a control tape m the control means 10; a ratchet 40 permits advance of the tape each time a cam 47 in the control means 11 is operated. Pneumatic sensing and operation of permutation type-selecting control.-The perforated type is pneumatically sensed and pneumatically conveyed via conduits 41 to pneumatic actions 42 in the control translator 11, to selectively position slides 45 so that only one seeker 46 is allowed to drop by the cams 47. Type-lever action.-The selected seeker via link 27, key lever 25 and associated fork 25 shifts a hook 56 and a cam 50 is rotated by a spring so that it engages the power roll 15. A bell crank 56 is rocked about pivot 61 and actuates linkage 62, 65, 29 and so open a toggle 20, 21 and effect typing action. Tape-perforating.-The typewriter may simultaneously produce a punched tape.
