Prior to use a screw cap 17 maintains the needle and holder in an extended position. Removal of the cap permits retraction of the needle under the influence of spring 16 and causes rupture of the seal 5. The seal 26, on the forward end of the inner tube is provided with one or more opening 27 in the lateral portions beyond the constriction 23.

Title: Suspension system in a motor vehicle
IPC: F16F9/096
Filed: 1972-10-17
Abstract: 1408939 Self-levelling suspension units NISSAN MOTOR CO Ltd 17 Oct 1972 [23 Oct 1971] 47800/72 Heading F2S A self-levelling piston-cylinder suspension unit comprises a variable volume liquid chamber 11b communicable to source and sink, a member 18 axially slidable in the cylinder, valves 28, 30 for selectively providing liquid communication between the cylinder chamber and source through an inlet passageway 25 and between the cylinder chamber and sink through an outlet passageway 26, detecting means 28b, 30c disposed between the valve means and the sliding member 18 to detect axial movements of the sliding member 18 in excess of a predetermined amount and actuate the valves, and springs 23, 24 holding the sliding member 18 in a neutral position where neither valve is actuated. In operation, dynamic oscillations of the piston in the cylinder are damped by throttling passages 38 in the piston or 38a in the passageway leading to a hydropneumatic spring 32, the level-regulating sliding member 18 being unaffected. However changes in piston position resulting from a change in the static load on the piston are reflected by a change in position of the sliding member which causes the unit to return to its mean length. If the static load is increased, the unit contracts. The spring 24 pushes the sliding member 18 upwards to contact a projection 28b on the inlet valve member and open the inlet valve against its spring bias. Liquid from the source enters the cylinder forcing the piston back out so that the unit resumes its mean length, the sliding member moving downwards under the action of the spring 23 to enable the inlet valve member to close under the action of its spring and stop the supply. If the static load is reduced, the unit extends. The spring 23 pushes the sliding member 18 downwards. A recess 20 in the sliding member engages a stop 30c on the outlet valve member and pulls it down to open the outlet valve against its spring bias. Liquid flows out of the cylinder and the unit contracts to its mean length, the sliding member 18 moving upwards under the action of the spring 24 to enable the outlet valve to close. The embodiment of Fig. 2 (not shown) has means for adjusting the mean length of the unit. In the embodiments of Figs. 3 and 4 (not shown) the valve means are modified so that they respond to smaller variations in load. In each embodiment, the inlet and outlet valves are controlled by separate control valves.

Title: A device for transmitting multiple information
IPC: G08C15/06
Filed: 1964-12-04
Abstract: 1,094,095. Electric selective signalling. CHARBONNAGES DE FRANCE. Dec. 4, 1964 [Dec. 6, 1963], No. 49504/64. Heading G4H. In a signalling system using frequency signals, a switching device in the output of a fixed-frequency oscillator in the transmitter and a detector in the receiver are each responsive to reference voltage signals produced at the polarized outputs of a polyphase generator. Referring to Fig. 1, the 3-phase signal on the district network 5 of a mine effectively scans three switches I 1 ,I 2 ,I 3  cyclically in turn via transformer T2. If one of the switches is closed when scanned, transistor D is rendered conducting to allow the output of a constant-frequency oscillator 6 to pass through a transformer T1 to telephone wires 13. Thus three two-state indications may be sent per cycle (of the 3-phase signal). Another frequency may be applied to wires 13 simultaneously using the arrangements shown dotted. Six indications may be sent per cycle without using a second frequency by having three extra secondaries on transformer T2, each to provide a voltage in anti-phase with that from a corresponding one of the original secondaries. These extra secondaries control the transistor D like the original secondaries, through corresponding switches (Fig. 3, not shown). Fig. 6 shows a receiver for the full-line, Fig. 1, system, lines 1 being connected to lines 5. The 3-phase signal on lines 1 effectively scans relays Re1, Re2, Re3 cyclically in turn via transformer T3, and if a filter F connected to lines 13 receives the oscillator frequency when a particular relay is being scanned, a corresponding silicon-controlled rectifier Th1, Th2, Th3 conducts to energize the relay. To prevent errors due to phase shifts in the system, the fractions of a cycle allocated to successive relays are separated by dead periods, this being achieved by secondary windings S<SP>1</SP> 1 , S<SP>1</SP> 2 , S<SP>1</SP> 3  of transformer T3 each having less coils than any one of the other secondaries S 1 , S 2 , S 3 , together with the diodes and transistors shown. Since in general the same data (switch positions in the transmitter) will be transmitted in several successive cycles, capacitors are shown across the relay coils to prevent on-off oscillation. A similar receiver for use with the Fig. 3 (not shown), transmitter comprises tapped seriesconnected secondaries on transformer T3 (Figs. 9, 12, not shown). Fig. 13 (not shown) shows a basically similar receiver with switches for selecting any six of twelve twelfths of a cycle and using the data in the six to control lamps.
