Title: Improvements in or relating to lubricating devices
IPC: F16N7/30
Filed: 1927-11-30
Abstract: 299,625. Bliss, J. Nov. 30, 1927. Manually-actuated multiple-way valves.-In a displacement lubricator comprising independent valves 19, 31 controlling the outlet of oil from a chamber 11 and the inlet of steam to a chamber 10 respectively, the two valves are coupled to a single operating member 34. The member 34 is connected by a link 37 to a crankarm 36 on the spindle of the oil valve 19, and is secured to a shaft 33 which carries, beneath the valve 31, a cam 35. A jockey valve 32 is arranged within an axial passage in the valve 31. The arrangement is such that, during the first part of the movement of the handle 34, the valve 32 alone is opened, the accompanying movement of the valve 19 being insufficient to open the valve. During further movement of the handle, the valves 19, 31 are both opened. The position of the valves is indicated by an arm 38 on the shaft 33 traversing a scale 39 which is provided with stops to limit the motion. A spring-pressed detent 40 is adapted to snap into a recess 41 when the valve 32 only is open.

Inventor: MAY EDWARD
IPC: H03K17/288
Filed: 1953-11-27
Abstract: 784,507. Discharge-tube relay circuits. BIRLEC, Ltd. Nov. 29, 1954 [Nov. 27, 1953], No. 32935/53. Class 40 (6). In an A.C. operated electronic timing device in which a capacitor connected in the grid circuit of a gas discharge tube is discharged so that the tube is cut off and is subsequently rendered conducting, when the capacitor is recharged, to operate a solenoid, a switch is connected across the capacitor and is closed by the mechanism which is controlled by the solenoid to discharge the capacitor and is then re-opened to permit the capacitor to re-charge. The Figure shows an electronic timer circuit in which with switch 8 normally open capacitor 13 is charged from the A.C. mains supply across terminals 2, 3 via transformer 10, 11 and rectifier 14 until after a time determined by the time constant of network 15, 16, 13 and variable resistors 24, 25 thyratron 9 fires and operates solenoid 7. When the external mechanism controlled by solenoid 7 is operated, switch 8 is closed thereby and discharges capacitor 13 to cut-off thyratron 9 during the next negative half-cycle of A.C. supply at its anode. Switch 8 is then opened, capacitor 13 recharges, and the timing cycle is repeated. Switch 17 across resistor 16 provides a coarse control of the timing period. An auxiliary secondary winding 12 of the mains transformer is connected to the heater 29 of thyratron 9 in parallel with the heater 26 of a thermal delay switch 27 so that A.C. is not applied to the anode/cathode current of the thyratron until after the heater has been energized for a period.

Filed: 1971-07-15
Abstract: 1330233 Seats ESSEX INTERNATIONAL Inc 15 July 1971 [20 July 1970] 33212/71 Heading A4J [Also in Division E2] Apparatus for locking the forwardly foldable backrest of a vehicle, seat in an in use position comprises a latch member 7 movable between latching and unlatching positions, operating means 21 movable between first and second positions, motion transmission means 18 interconnecting said operating means and said latch member for moving the latter from its latching position to its unlatching position in response to movement of said operating means from its first position to its second position, energizable and de-energizable rotary motor driving means 27, means 26 coupling said driving means to said operating means for moving the latter from its first position to its second position in response to energization and consequent rotation of said driving means in one direction, and yieldable means 11 acting on said latch member for restoring the latter to its latching position and restoring said operating means to its first position via said motion transmission means in response to deenergization of said driving means. As shown, the operating means is a lever 21, and the coupling means is a gear segment 25 carried by the lever and a pinion 26 carried by the motor driving means. The latching apparatus is mounted, in use, on the seat back and the latch member is engageable with a keeper stud 14 carried by a bracket 15 secured to a frame 2 which supports the seat cushion; when the latch member is engaged with the stud it maintains the seat back in its normal position relative to the cushion frame 2. In use, the motor driving means 27 is connected to the vehicle battery via a switch which is in the open position when the driver's door is closed; opening the driver's door closes the switch which energizes the motor driving means 27 which operates to disconnect the latch member 7 from the stud 14 so, that a rear seat passenger can tilt the seat back forwards; the operation of the motor driving means 27 pivots the lever 21 in withdrawing the latch member and this movement also puts a resistor in series with the motor driving means so limiting the current supply to the motor when the motor is stalled by an arm 19 of the latch member engaging a stop 38 and L- shaped link 4 by which the seat back is pivoted to the cushion frame 2. The resistor is carried by the lever 21 and a brush is mounted on a bracket 23, which supports the means 27, and which in the latching position engages a conductive strip also carried by the lever and which is normally earthed; when the lever nearly reaches the end of its rocking movement the brush moves off the strip into engagement with one end portion of the resistor and since the other end portion of the resistor is earthed to the lever the resistor is inserted into the motor circuit. When the driver's door is closed the switch is open thereby disconnecting the motor driving means from the battery and the spring 11 is then operable to return the latch member to its latching position.
