In a taximeter with a time and distance drive shaft 1 (Fig. 1, not shown) operated over stepless one-way clutches 17, 17<1> the time drive is provided by the armature 32 of an electromagnet 33 driven at constant frequency. The armature 32 is spring loaded 30 against a screw 34 whose position may be varied to limit movement of the armature. The armature 32 is mounted by way of a plate 28 on a clutch 26 which rotates in one direction only within a case 17<1> whose opposite direction of movement is prevented by a spring brake 43. The case 17<1> is connected to the shaft 1 by a pin 21 mounted in a slot 22 of a size such that the pin is at the right of the slot when the vehicle is stationary and hence operates the shaft but is towards the left during movement of the vehicle and hence the distance drive overrides the time drive. The distance drive clutch 14 is driven from one of several gears 5 operating a pinion 16 through one of several pinions 38 positioned by a cam 42 according to the required tariff. The shaft 1 rotates a cam 6 to rock a bar 7 which rotates a wheel 9 geared 10, 11 to a counter 12.

Abstract: 1347340 Catheter insertion device VICRA STERILE INC 8 Oct 1971 [16 Oct 1970] 46965/71 Heading A5R  A catheter insertion device which can be removed from the catheter after insertion thereof comprises a hollow needle 10 with a piercing end and secured at its other end to a hub 14, both needle and hub having longitudinal slots 54, 52; a flexible catheter 26 with one end disposed inside the needle 10; and a clip 20 which can be positioned to prevent the catheter 26 moving inside the needle 10. In the embodiment shown, clip 20 is movable in a slot 46 of a sleeve 16, the sleeve 16 being removably mounted on a projection 18 of the hub 14. Sleeve 16 and projection 18 define a channel 40. The clip 20 has a portion 42 which is located in the channel 40. In the position shown, the portion 42 presses the catheter 26 against a surface of the projection 18 and thereby secures it. This pressure may be released after insertion of the needle 10 in the body by moving the clip 20 forward to a region where the slot 46 of sleeve 16 is spaced further from the projection 18, as in Fig. 10 (not shown). The catheter 26 may then be slid through the needle into the body. The needle 10 is then withdrawn and the catheter 26 separated therefrom through slots 52, 54. The distal end of the catheter 26 can be surrounded by a flexible bag 32 secured to the sleeve 16, to define a sterile environment for a connector 28 and plug 30 which may terminate the catheter 26. In an alternative embodiment, Figs. 13 and 14 (not shown), the clip (92) is mounted in a slot (83) of a modified hub (80) and is removable therefrom through an opening (94).

The latter comprises two annular housing members 13, 14 clamped together to define a chamber 16 into which open air inlet ports 21 controlled by oscillating diaphragms 23 clamped at their inner edges by rings 25. The latter include ports 30 to subject diaphragms 23 to the pressure oscillations within combustion chamber 43 and define with housing members 13, 14 annular gaps 29 for flow of incoming air. A central partition 31 directs the air radially inwards towards a convergent-divergent fuel nozzle assembly 35 into the throat of which fuel is drawn via duct 38 from tank 6. The fuel and air flow through an opening 32 in partition 31 into pipe 41 where mixing is assisted by swirler 42 prior to ignition by plug 44 and discharge of the gases into combustion chamber 43. Fuel nozzle 35 has a high resistance to backflow, but any backflow that does occur is collected in chamber 40 which is connected to a compressed air conduit and a return to fuel tank 6. The carburettor is also provided with a passage 37 connected to a starting air pump 4. Liquids to be dispersed by the apparatus are stored in a tank 7 having a removable partition (59, Fig. 5 not shown) defining separate chambers (58) each of which has a control valve 8 connected via pipe 60 to an injection nozzle 61. The latter is disposed in a tube 62 forming a continuation of combustion chamber 43, the outlet end of tube 62 being stepped (at 74, 75 Fig. 11 not shown) to cause recirculation and improved mixing of the injected liquid. Several injection nozzles 61 may be provided. An air cooling jacket 11 surrounds chamber 43 and tube 62. Each control valve 8 has two inlets (64, 65 Figs. 7 to 10 not shown) pressurised by connection to the carburettor starter air passage 37 and arranged such that in one valve position (Figs. 7, 8) tank 7 is pressurised and pipe 60 is purged whereas in the other position (Figs. 9, 10) liquid is forced from the tank into pipe 60. The apparatus is mounted on a frame 2 and may be pivoted about a horizontal axis 3.

Abstract: 1,079,800. Data transmission. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 8, 1965 [Nov. 6, 1964], No. 47324/65. Heading H4P. In a data transmission system in which errors are corrected by repetition a supervisory return signal, upon changing from a first state to a second, causes the movement of the punched tape at the transmitter to be reversed, and, upon returning to the first state, to revert to the original direction of movement for retransmission of the erroneous signal. As described, 8-bit parallel signals and a clock signal are sent on a voice frequency line. Transmission occurs while the first state of the supervisory signal is returned from the receiver. Upon detection of error and at the end of a received clock pulse the second state is returned, and transmission ceases when the character currently being sent is completed. The transmitter tape now steps backwards under control of the clock. When the receiver detects a clock pulse but no data the return signal reverts to its first state. This change in state causes transmission from the tape to restart at the next clock pulse, the first signal retransmitted being the erroneous signal. The receiver punched tape record contains only correct data. Should the repeated erroneous signal be faulty on reception an alarm is actuated at both the receiver and transmitter. Should the first signal transmitted, after setting up the connection by telephone, be faulty an alarm is actuated.
