Title: Hypodermic syringe
IPC: A61M5/20
Filed: 1974-07-29
Abstract: 1449986 Hypodermic syringe PHILIPS GLOEILAMPENFABRIEKEN NV 29 July 1974 [1 Aug 1973] 33430/74 Heading A5R A hypodermic syringe of the type actuated by spring power comprises: a cartridge 106 which consists of an ampoule and attached cannula 150, said ampoule being a cylindrical sleeve 136 slidably carrying a piston 148, said sleeve 136 being open at one end and having means 81 at the other end for rigidly mounting said cannula 150; a resilient sheath 250 covering the cannula 150 to maintain said cannula 150 in sterile condition, said sheath 250 being of cylindrical form having a closed and an open end, said open end abutting said cartridge 106; and a cartridge holder 104, slidably mounting said cartridge 106, formed with a closed end which is provided with a centrally positioned aperture 158 of a diameter less than that of the sheath 250 but greater than the cannula 150, whereby on actuation of the device, the spring power means forces the cannula 150 through the sheath 250 and through the aperture 158. The cannula mounting comprises a hub 81 having a shoulder 82 against which the sheath 250 abuts. An outer sleeve 100 contains the cartridge holder 104, and the spring power assembly 200, which is mounted in a sleeve 192 fitted by means of locking ribs 199 into the outer sleeve 100. An inner sleeve 101 is fitted within sleeve 192. A plunger 162 has a head 164 with tabs 168 extending radially and engaging the rear end of the ampoule. Plunger 162 is held inoperative by lugs 186 at the end of detent arms 184, which lugs latch on to face 122 of the inner sleeve 101. The coil spring 138, concentric with the plunger body is held compressed between the plunger head 164 and the end wall of sleeve 101. A safety pin 144 attached to a cap 142 prevents inadvertant operation of the device. The inside of the forward end portion 156 of the cartridge holder 104 is formed with ribs 157 against which the sheath 250 bears to prevent misalignment of the cartridge during storage. Operation of the device is by placing the forward end 156 on the patient and removing the cap 142 and pin 144. Pressure of the tapered end 156 on the patient causes relative motion between sleeves 192 and 100, whereby a cam surface 198 cams the lugs 186 together until they pass through hole 120 and allow spring 138 to advance the plunger 164 and cartridge 155 thereby inserting the cannula 150 through the sheath 250 into the patient until the cartridge is arrested by the resilience of the sheath 250 (Figure 2, not shown). The tabs 168 then deform to allow the plunger to advance the piston 148 in the ampoule injecting the medicament. During the injection the resilience of the sheath 250 acts to slightly retract the cannula 150.

Title: Improvements relating to tape decks
Inventor: DRAPER ALBERT ERIC
IPC: G11B15/22
Filed: 1958-10-20
Abstract: 867,408. Magnetic recording. COLLARO Ltd. Oct. 5, 1959 [Oct. 20, 1958], No. 33432/58. Class 40 (2). In a braking mechanism for a tape deck having two spool carriers both rotatable in either direction, the braking force on the spool from which tape is being wound is arranged to be greater than the braking force on the other spool which is receiving the tape. Brake bands 22, 25, respectively extend around an arc of each flywheel 4, 6 associated with respective spool carriers 5, 7; the two ends of each band being respectively anchored to a fixed support 23, 26, and attached at 23a, 27 to a rigid member 24 pivoted at 27a to a link 28 longitudinally displaceable, and held by a catch, against the action of a spring 33 which urges the link downwardly, causing the brake bands to operatively engage the flywheels 4, 6. If the spool carrier 5 is rotated anticlockwise, thereby receiving tape, and the brakes are applied, the resulting tension at the end 23a of band 22 will rock the member 24 in a clockwise direction about pivot 27a, thereby increasing the tension in the brake band 27 to produce a greater braking force on the spool carrier 7. In a modification, the link 28 is pivotable at its upper end, the pivot 27a at its lower end being either retained or replaced by a rigid connection between the members 24 and 28.

Abstract: 818,586. Kinematographic cameras. BOLSEY, J. Dec. 2, 1955 [June 17, 1955], No. 34545/55. Class 97(1) In a kinematographic camera, the shafts of two interconnected gear trains are journalled in mutually perpendicular planer partition walls and the three compartments defined by these walls contain, respectively, the drive motor and first gear train; the film magazine; the shutter, film feed claw and the second gear train. As shown, one train 16, 31, 33 and 34 is carried by a wall 11 which is at right angles to a wall 14 carrying the other train 41, 42 and 44 and bevel gears 38, 39 interconnect the trains. A spring motor 16 forming the first gear in the first train has a spring 22 wound by handle 28. Handle 28 rotates spring carrying core 18 about stationary pin 19 and core 18 engages the end 21 of spiral spring 20 which grips pin 19 to prevent spring 22 from unwinding. Spring pawls 29 engage rachet 25 so that handle 28 is prevented from turning cone 18 in the wrong direction. A governor 37 is provided on the shaft of pinion 34. Film feed claw 59 is driven by an eccentric 57 on the shaft 45 of gear 44 which also carries shutter 56. The film engaging tooth of the claw is held on the film by the light spring pressure of a leaf spring at the pivot of the claw. The play allowed by a conical end 61 of the pivot pin of the claw enables an inclined face on the tooth to ride up over the edge of the film perforation and thus disengage the claw for its return stroke. The camera mechanism is released, on depressing button 71, by lowering lever 66 below the level of wall 14 and out of the path of claw 59. A gear ring 46 is mounted in frictional engagement with the spring motor 16 and normally provides a non-slipping drive to the take-up spool through gear 47. Ring 46 carries a projection 50 for operating a frame counter and a spring tension indicator (not described). The take-up spool is positively driven at the angular velocity at which the linear speed at that radial distance from its axis of rotating which is mid-way between the radius of the empty spool core and the radius of the completed film coil is equal to the linear speed at which the film is fed at the film gate. The film is thus initially wound loosely on the core and windings are tightened only at the moment when the coil is completed.
