Abstract: 1,241,577. Suturing instrument. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT KHIRURGICHESKOI APPARATURY I INSTUMENTOV. 22 Aug., 1968, No. 40373/68. Heading A5R. A suturing instrument comprises a hollow body 1 containing a movable tubular rod 6, a movable handle 2, a staple ejector 9, a split ring washer 10 loosely set on a puncher 7 which is threaded onto the front end of the rod 6, a reciprocating stem 17 and a detachable head 19. As shown, the head 19 is screwed to the pointed end 18 of the stem and located by a guide key 25, and comprises a cylindrical part 22 and a connected tapered portion 21 which can rotate independently about its axis, portion 22 having a cylindrical recess 23 to accommodate a projection 11 on the puncher. The instrument is operated by removing head 19, locking the handle 2 with lock 15, withdrawing the stem 17 into the body 1 where it is held by swivel retainer 35 engaging in groove 33 and introducing the instrument perorally into the patient. The stem 17 is then moved all the way forwards and the pointed end 18 pierces the esophagus. The stem is then free to rotate about its own axis by virtue of the groove 34 engaging with a support washer (not shown) in the back of the body 1, beneath nut 31, thus permitting section 21 of the head to be fixed to the stem 17 by rotating the stem by means of its tailpiece 20. The stem is brought back close to the body 1, by tailpiece 20, with the lower tissue attached to it, the retainer 35 engages the slant groove 32 and is rotated to set the gap. The two tissues are thus brought together between the front of the puncher 11 and the recess 23 of the head 19. Lock 15 is released and handles 2 and 3 are brought together causing staples to be driven through the tissues and bent against depressions 24 in the back of head 19, and an excision to be produced between edge 37 of the recess 23 and bevelled edge 36 of the puncher 7.

Title: Rotary power tool such as a power wrench
IPC: B25B23/145
Filed: 1975-10-06
Abstract: 1498968 Torque-controlled power tools; wrenches ROBERT BOSCH GmbH 6 Oct 1975 [19 Dec 1974] 40785/75 Headings B3C and B3N In a power tool, particularly a compressed air operated screwdriver, the motor is switched off at a predetermined overload torque by means of a disengageable coupling device in the transmission which comprises a driving portion 22 Figs. 2, 3 drivably coupled to a driven portion 38 via adjustably spring preloaded pressure ring 49 acting on coupling members (balls) 48 located in bores in the portion 22 and in axial recesses 47, Fig. 2a, in the driven member 38. At the overload torque, balls 48 ride out of the recesses against loading spring 55 to partially uncouple the drive (Fig. 4, not shown). At the same time, pressure ring 49 forces locking members (balls) 72, 73-in aligned bores 36, 64 in portion 22 and in a locking pin 61- inwardly against spring 75 acting on ball 74. This allows the normally locked pin 61 to move axially forwardly relatively to the driving portion Fig. 5 and hence shut-off valve spring 8 closes the valve 7, which was held open by the pin 61 via rods 24, 11, and the motor is switched off. In the arrangement shown, valve 7 is opened by pressing the tool against a workpiece which causes the coupling assembly and rods 24 and 11 to move to the right. When the tool is released after the overload torque is reached, recuperating spring 71 moves the coupling device to the right relative to the pin 61 and the assembly resumes its Fig. 1 position. There may be single radial bores 36, 64 in portion 22 and pin 61 and spring 75 may be replaced by a spring (75<SP>1</SP>) in the radial bore Fig. 6, not shown.

Title: A Tracer Arrangement for a Copying Machine Tool
IPC: B23Q35/26
Filed: 1966-09-13
Abstract: 1,151,514. Copy-milling. NASSOVIA WERKZEUGMASCHINENFABRIK G.m.b.H. 13 Sept., 1966 [21 Sept., 1965], No. 40899/66. Heading B3K. In a copying machine tool, e.g. a copy milling machine, having a pivotally mounted tracer adapted to follow the contour of a pattern and to control the feed movements of the tool through control means which are responsive to the deflections of the tracer on a lead or delayed action principle, the pivotal mounting of the tracer is such as to allow adjustment of the position of the pivot point axially therealong to adjust the deflection ratio. A tracer 2 carrying a replaceable pin 4 is pivotally mounted at a pivot point S in a tracer housing 1, the pivotal mounting of the tracer 2 being vertically adjustable in a guide slot 12 to which it may be clamped in selected position by means of a clamping nut 15. A pointer 16 indicates on a fixed scale 17 the effective length of the upper part of the tracer while a slidably mounted scale 18 with a stop member 21 pivotable into a measuring position in which it locates the end of the tracer pin 4 can be used to determine the length of the lower part of the tracer. Where the upper or lower parts of the tracer are to be of equal length, i.e. a deflection ratio of 1: 1, the scale readings at pointer 16 on both scales will be equal and if the pin 4 is replaced by a pin of different length the pivot point 5 can be adjusted till this condition is again realised. The pivotal mounting may be of the ball joint type comprising a part-spherical member having a central bore and a ball bearing enclosed therein in which the tracer is axially movably mounted (Figs. 3, 5, not shown) or may be of the cardan joint type, the inner ring of which forms a sleeve in which the tracer is axially slidable. The adjustably pivotally mounted lever may be used with control elements, e.g. hydraulic valves, or electrical elements operating on the lead or delay control principles, and in the latter case in order to secure the tracer axially a cardan joint is provided in which the inner member is formed by the tracer itself and the outer member rests through a ball bearing on the base of the housing (Figs. 5, 6, not shown). A second fixed scale (36), (Fig. 4, not shown), may be mounted on the housing and a movable vernier scale (37) associated therewith to provide for a direct reading of the deflection ratio. It is stated that with a delay control copying arrangement variation of the deflection ratio can be used to alter the scale of reproduction from the master pattern, while with a lead control arrangement the cutting speed can be varied.
