Abstract: 712,123. Substation circuits. POSTMASTER GENERAL. Nov. 27, 1952 [Sept. 27, 1951], No. 22619/51. Drawings to Specification. Class 40 (4) The sensitivity of a telephone set is automatically reduced when the set is connected to a short line, by the use of the direct current flowing through the set from the exchange to vary the magnetic flux in a ferromagnetic circuit incorporated in or associated with the set. In one embodiment the receiver has pole pieces of a material whose incremental reluctivity varies in accordance with the magnetomotive force applied across it, and the direct current is passed through a coil on the receiver core. Alternatively, the direct current is used to vary either the impedance of a transductor connected across the line between the set and the exchange or the loss in the induction coil incorporated in the set. In the latter case, the induction coil is preferably of the type described in Specification 712,124, [Group XXXV].

Abstract: 186,501. Angel, L. V., and Nunn, G. L. Aug. 26, 1921. Scaling-wax and the like, applying.-Relates to apparatus for applying a congealable composition to the necks of corked bottles. The bottles 40 are placed in a box 30, 31, Figs. 1 and 3, which is inverted and rests by means of shoulders 34 on a vertically-movable frame 3, the bottles being prevented from falling out by rods 41 passed through slots 39 in adjustable ends 35. The frame 3 is depressed by a pedal 10 against the action of a spring 9 and weight 5 on a lever 6, the limit of downward travel being adjustable by pins 15 adapted to be placed in holes 14 in a sliding upright 2. The inverted bottles are immersed to the desired depth in a trough 17 containing sealing-composition 16 kept fluid by the. action of a burner 20 on a water or like jacket 18. The level of the composition 16 is kept constant by admitting air from a reservoir 23 of compressed air into a casing 25 to force the fluid to maintain a level indicated by an adjustable gauge 28<a>. If the level is too high, a cock 29 is opened to allow the air in the casing to escape to the atmosphere. Alternatively the level may be adjusted by a plunger and cylinder. The boxes 30 may be collapsable so as to be assembled about bottles in rows. A metal disc or washer may be fitted to the corks before dipping so that on withdrawal of the cork the composition is removed from the neck. In the case of bottles without a shoulder to be engaged bv the rods 41, rubber rings may be applied to form temporary shoulders. 'When heavy bottles are to be sealed, an overhead pivoted and weighted arm may be used to invert a trolly containing the bottles.

Title: Improvements relating to Oscillating Vane Type Actuators
Inventor: COLLING NORMAN WHITFIELD
IPC: F15B15/28
Filed: 1966-05-20
Abstract: 1,150,472. Oscillating vane actuators. ENGLISH ELECTRIC CO. Ltd. March 17, 1967 [May 20, 1966], No.22713/66. Heading F1F. An oscillating vane actuator comprising a vane chamber 14 filled with liquid and in which a vane 15 moves with limited angular movement, first and second pressurizable operating chambers 11, 12 normally open to atmosphere, partially filled with liquid and connected through ducts 18,19 controlled by poppet valves 20, 21 with the vane chamber and an equalizing chamber 13 connected permanently to atmosphere through a filter 22 and normally connected to the operating chambers 11, 12 through non-return valves 23A, 23B, includes a liquid flow path connecting the operating chambers and valve means in each of the operating chambers controlling the liquid flow path and the atmospheric openings in the pressure chambers. In operation, a switch 33 is depressed to energize a valve 27 to direct compressed air from a reservoir 26 to act on diaphragms 28, 29 to open valves 20, 21. One or other of valves 24, 25 is then energized to direct compressed air to one or other of the operating chambers 11, 12, e.g. chamber 11 whence the liquid in that chamber is initially transferred through the duct 40 to the chamber 12 until the liquid level in the chamber 11 falls sufficiently so that a float valve 41 closes the end 47 of the duct 40. The valve 23A will then close and the pressurized liquid will pass into the vane chamber 14 to move the vane 15 clockwise. Should for any reason, due e. g., the encountering of an excessive load, the vane refused to move, liquid will leak past the vane and flow into the chamber 12 to raise the liquid level in that chamber to eventually raise a float valve 51 to close a duct 56 communicating with atmosphere to cause the valve 23B to close and allow pressure in the chamber 12 to build up to equal that in the chamber 11 so that oil flow ceases and thus mitigate against any major fault occurring in the actuator. The switch 33 co-operates with a further switch 35 and a cam 36 so that the vane on the breaking of the switch 33 may be stopped in any one of a number of angular positions.
