Title: Turn wrest plough
IPC: A01B3/18
Filed: 1927-02-04
Abstract: 265,607. Wenger, R. Feb. 4, 1927. Turn-wrest implemests; adjusting and lifting parts; draught devices. -Mechanism for lifting and reversing a turn-wrest plough consists of sprocket-wheels adapted to be clutched to the wheel axle and connected by chains to a drum on the plough beam, the drum and beam normally being locked against rotation by a latch but being caused automatically to turn through approximately 180‹ when the latch is pulled back and the plough falls. The beam 5 passes through a cross-piece 11 pivotally supported by arms 10 pivoted on the axle 3. Its inner end is mounted in a head rigidly connected with the part 11 and adjustably connected by a screw 18 to a bridgepiece 17 carried by the arms 10. The chains 34 from the sprocket-wheels 24, 25 pass over elevated guide pulleys 33 and round opposite sides of the drum 13 on the beam 5. The clutch 27 for connecting one or other of the sprocketwheels 24, 25 to the axle 3 to lift the plough is operated by a lever 37 which also controls locking-pawls 30 engaging ratchet teeth on the sprocket-wheels. The latch 42 for locking the drum 13 and beam 5 against rotation is controlled by a rope 41 connected to a handle on the lever 37. The latch is carried by the drum and engages notches in a member 12 adjustably connected to the cross-piece 11 by screws 48, which are geared with the screw 18 by chain gearing. Adjustment of the member 12 regulates the angle through which the beam turns as it falls, after the pawls 30 and latch 42 have been pulled back. The lever 37 is jointed and provided with a spring. As it is depressed to lift the pawls 30 it engages a V- shaped notch in a block 43 and is thus forced into a central position with the clutch disengaged. The draught bar 1 is pivoted and is adjustable bv means of a worm 45 and toothed segments 46, 47.

Title: Cylinder lock
IPC: E05B27/08
Filed: 1972-01-24
Abstract: 1376011 Locks KEYSTONE CONSOLIDATED INDUSTRIES Inc 24 Jan 1972 3312/72 Heading E2A A change-key barrel lock comprises an axial-tumbler, rotatable barrel assembly 31, 34, 28 of known type, provided with radially movable pins 68 which are normally biassed inwardly by O-ring 69 so as to clear indexing notches 65, 66 in an indexing ring except when a correct key 79 is inserted. This key has notches 89 to receive the inner ends of pins 68, so that the key can rotate the barrel and can only be withdrawn in its 'locked' position, and a special key 91 is required for changing the disposition of tumblers 55, 56, 57 to receive a changed key bitting. In normal use, the key 79 raises pin 78 against resilient ring 62 so that its interface with a follower 76 coincides with the interface between the barrel 31 and the index ring 61, thus permitting rotation. The key is splined at 39, 85 to a central spindle 36 which carries the rotatable element 31 and 28, and also a locking bolt (11, not shown). The change-key 91 has a slot 97 for accommodating the pin 68 at its top surface but is completely relieved at 98 at its bottom. In consequence it may be turned 30‹ to a displaced position 26 and withdrawn leaving the top pin 68 in a displaced slot 66 in the detent ring. A change-key with a different bitting can then be inserted and rotated to the 'locked' position. The effect of this is to change the arrangement of the change tumblers 57 relative to tumblers 55 and locking tumblers 56. As shown, the lock is of axial tumbler type for use with keys having appropriate bitting 88, but a radial pin or plate tumbler lock could be used.

Abstract: 1,177,981. Electro-physical measurement - moisture. KINGSBURY TECHNOLOGY Inc. Jan. 23, 1967 [Sept. 14, 1966], No. 3344/67. Heading G1N. The moisture content of e.g. bales of paper pulp is measured while they are being compressed by attaching an insulated "capacitor plate" (110) to the platten (102) of the hydraulic press (100) and measuring the capacity between the plate and the base (101) at two different spacings, by measuring the frequency change of an oscillator circuit to which the capacitor unit is connected. The frequency may be measured by gating the oscillator to a counter at pre-selected platten positions. Measuring circuit. In one embodiment Fig. 3, the capacitor unit tunes the variable oscillator 301 of a B. F. O. The output from the detector 304 is compared with a reference value 201 in servo-amplifier 202 to control the trimming capacitor 205. As the platten moves down switch SW-1 disables the trimming circuit at height h1 and at height h 2  switch SW-2 operates the gate 311 to pass pulses from the B.F.O. mixer 303 to the counter 313 for e.g. 1/100 second. Switch SW-1 resets the counter in the up position of the platten. In an alternative arrangement described in Divisional Specification 1,177, 984, the trimming capacitor is set with the cell empty. Modifications. Fig. 4 (not shown) as the platten continues to move down after the count triggered by SW-2, switch SW-3 reverses the counter, and switch SW-4 initiates a further (backwards) count and finally switch SW-5 triggers a printer to record the frequency difference at the two platten heights. Fig. 5 uses a SERVO-NULL-INDICATOR system, the trimming capacitor is controlled similarly to Fig. 3 to stabilize the detector output 305 at the reference potential 201 until SW-2 operates to energize relay RL transferring the input and output of the servo-amplifier 202 to an indicator position feedback potentiometer 405 and an indicator drive motor 401. The indicator records the frequency change until SW-4 opens to de-energize the drive motor.
