Abstract: 1290472 Typewriters OLYMPIA WERKE AG 22 Jan 1970 [1 Feb 1969] 3248/70 Heading B6F Type lever drive mechanism comprises a bar 12 having an edge 13 which in operation engages an abutment 117 on a pawl 17 connected to a selected type lever, the movement of the edge 13 being in a path (113, Fig. 1) whereby the edge 13 strikes the abutment 117 in the initial driving direction but misses the abutment, or any other abutment corresponding to a successively selected type lever, on the return stroke. The bar 12 is driven from a shaft 2 through a crank pin (4, Fig. 1, 3) on a disc 3, a lever 5 coupled to a bell crank lever 6 mounted on a fixed shaft 8, and a lever 14 coupled to the bell crank lever 6 and to the lever 5 at 16. Depression of a key lever 27 engages a clutch (not shown) to initiate drive to the shaft 2 and displaces a corresponding pawl 17 into the path of the edge 13 of the bar 12, the pawl 17 being connected by a link 19 to a type lever (not shown). The force of type lever impact is adjustable by altering the position of the pin (4) with respect to the disc 3 through rotation of an eccentric (4a). Adjustment is effected by a keyboard lever coupled by a link 45 to the eccentric (4a) through links 42, 38, 37, 35. The adjustment may be automatic on case shift.

Abstract: 1295934 Blood transfusion bag JINTAN TERUMO CO Ltd 28 May 1970 [28 May 1969] 25780/70 Heading A5R Apparatus for the transfusion of blood comprises a fluid transfusing bag 1 made of flexible plastics material having a fluid outlet connection 7, which has a sealing membrane 8 and the outer end of the connection having inserted into it the needle portion 11e of a cannula 11 which is attached to the fluid outlet connection by a thin walled tube 9. A heat shrinkable rubber tube 10 bridges the thin wall tube and a conduit 12 mounted on the cannula 11 so that when the bag is steam sterilized, steam passes under the tube 10 into the tube 9 and through the bore 11c through the conduit 12 into a separate bag 13. The tube 10 then shrinks causing the conduit 12 to be sealed off from the atmosphere. After blood is transfused into bag 1 via needle 5, transfusion tube 4 and ball valve 3 then bag 1 is centrifuged to separate blood plasma from blood corpuscules, and after penetration of the needle 11e through the seal 8 the blood plasma is drawn off through bore 11c into the separate bag 13, from which it is administered to the patient. In an alternative embodiment, Fig. 4, (not shown), a medical fluid bag (21) may be connected to a cylindrical filter (22) by means of the thin walled tube, cylindrical connection member and heat shrinkable tube as described above. The filter (22) is connected to a cannula (24) by way of a tube 23.

The first carriage 3 which is mounted for E-W movement on slides 5 secured to blocks 6 mounted for N-S movement on slides 7, carries a pinion 11 meshing with a stationary rack 12 and a rack on a second carriage 9 supported for E-W movement on slides 8. When the work holder (not shown) is attached to the second carriage 9 the stitch length is increased whenever the work holder movement includes an E-W component. This may, it is stated be compensated by automatic variation of the speed of the sewing head under control of the template. Preferably the N-S movement of the work holder is also multiplied by a similar pinion and double rack arrangement (Fig. 2, not shown). It is stated that by modification of the gearing any ratio of movement can be obtained and provision may be made for altering the gear ratio and/or rendering the multiplying gear inoperative.

The rotatable body 18 is mounted, as shown, from a support 7 and is held until the peg 25 engages the recess 31 when fluid under pressure is then fed through a conduit 44 to urge a piston 33 which carries the pin 35, upwardly to free the body 18 for rotation. During lowering of the undercarriage 12 the jack 20 is extended until the leg 11 and body 18 reach the position 13, further movement being prevented by a stop (32), Fig. 4 (not shown), after which fluid under pressure is fed through a conduit 45 to drive the piston 33 and pin 35 down to unseat the peg 25 from its recess 31. In an emergency, fluid is supplied through a conduit 46 to force a piston 39 and a member 41 urged by a spring 40, downwardly to depress the piston 33. The undercarriage 12 is held in its fully retracted position 14 or lowered position by locking the jack 20, though separate locks for each position may be provided. The body 18 may be mounted directly on the aircraft. The jack 20 is connected to the aircraft structure and undercarriage leg 11 by universal joints. Fluid pressure is controlled by microswitches contacted by the undercarriage members in various positions.

To achieve this the template is moved intermittently by mechanism driven from the driving motor 4 by way of a Geneva mechanism 9 connected to a gearbox 17 by a shaft 18. The gearbox provides two pairs of output pinions 43, 44; 45, 46; each driven through electromagnetic clutches 47, 48; 49, 50; the pinions of each pair are driven in opposite directions when the appropriate clutch is energised to drive, in a selected direction, the rack 51 or 52 engaged by a respective pair. The racks are attached to carriages 55, 56 having rollers 63, 64 embracing guide rails 57, 58 disposed along respective edges of the template 6. The carriage 56 is movable between raised and lowered positions under the control of solenoids 87, 88. A lower slot (71) in the template, corresponding to slot 70, engages a raised tubular element (73, Fig. 5 not shown) rotatably mounted in a bearing (73a) in the work supporting surface of the apparatus and guides the template as it is fed by the racks 51, 52; the clutches 47-50 slipping to accommodate differences in the motions. Electrical circuitry (Fig. 7, not shown) is described which controls the stitching sequence by starting the machine, energising the clutches 47-50 as required for the profile selected by a plug in programme selector unit 85 and stopping the machine with the needle in a selected position as determined by the photo-electric device 21-25. A scissor type thread cutter (Fig. 6, not shown) actuated by a Dowden cable (104) and a solenoid then severs the threads to allow removal of the template 6.
