Inventor: BATES WILLIAM NOEL
IPC: E06C7/16
Filed: 1958-05-28
Abstract: 869,356. Ladders. MATTHEWS, C. H. Aug. 26, 1959 [May 28, 1958], No. 16966/58. Class 20(2) A ladder is attached to a tree, post &c. by a platform, the frame of which has a pair of divergent members 11 which engage the tree &c. 22 which is clamped by a strap 23. The members 11 form part of a frame comprising side members 10 and a cross member 9 mounted on parallel members 7 which with struts are connected to the ladder by bolts passing through hollow ladder rungs. The strap 23 is secured by a spring 24 at one end and a rope 26 on pegs 27 at the other. A board 13 of the platform is mounted on pivoted arms 14 so that it may be raised to allow access to the platform. A cross member 28 connecting the ends of the members 11 carries a pivotable V-shape bracket 30 for supporting the ladder against a branch or a part out of the vertical. According to the Provisional Specification a platform may be fitted also on the other side of the tree.

Title: Relay circuits
IPC: H01H47/00
Filed: 1974-04-18
Abstract: 1472275 Transistor switching circuits STANDARD TELEPHONES & CABLES Ltd 18 April 1974 17011/74 Heading H3T A guard circuit for a bi-stable relay RLY comprises a switch circuit TR4, TR5 having a pair of terminals which are connected in series with the relay coil between the terminals of a power supply V2, V0; a control terminal (junction of diode D2 and collector of transistors TR3) which can be clamped to inhibit current flow through the switch; and a capacitive feedback path C2 which prevents current flow through the switch when the voltage at the junction between the switch is driven beyond the voltage V 0  of the terminal to which the relay coil is connected. To ensure that relay RLY is initially in the state in which contact NC is made supply V2 is connected before supply V1 so that if contact NO is made current will pass through the switch TR4, TR5 to reset the relay to the state in which NC is made. To change the state of the relay supply V1 is connected and a positive signal is applied to input 11 to turn on transistors TR1, TR3 and discharge capacitor C1 through relay RLY thus setting it to the state in which contact NO is made. During the discharge pulse of capacitor C1, capacitor C2 hold the base of transistor TR5 and the emitter of TR4 at the same potential. At the termination of the pulse, diode D2 clamps the base of transistor TR5 to V 0 , so that in neither case can switch TR4, TR5 pass current. In order to reset the relay, the positive signal is removed from the input 11 so that transistors TR1, TR3 turn off and transistor TR2 turns on to charge capacitor C1 producing a pulse which will switch relay RLY back to its other state. In place of transistors TR4, TR5 a single bi-polar transistor, a single field effect transistor, or a combination of both may be used.

Title: Improvements in or relating to fluid control valves of compressor unloader means
Inventor: FARMERY GEORGE KENNETH
IPC: G05D16/06
Filed: 1961-05-15
Abstract: 935,567. Fluid-pressure servomotor control systems. CLAYTON DEWANDRE CO. Ltd. April 16, 1962 [May 15, 1961], No. 17572/61. Class 135. A control valve of a compressor unloader means comprises a spring- loaded diaphragm 2 forming a wall of a chamber connected at 5a to a compressed air reservoir. A plunger 6 is connected to the diaphragm and is movable in a stepped bore 7, 8. The end of the plunger co-operates with a valve member 16 which controls flow from the chamber through passages 14, 15 to a connection 18 leading to an unloader means. When the pressure in the reservoir rises to a predetermined value, the diaphragm is moved against its spring loading to raise the plunger until the valve member 16 abuts a seat 9. Further upward movement of the plunger opens the passage 13 to allow flow to the unloader means to stop compressor delivery and this flow acts on the lower face of the plunger to provide a rapid upward movement. As the reservoir pressure decreases, the plunger moves downwards to re-engage the valve member 16 and a further movement lifts the valve member of the seat 9 to allow flow from the unloader means to atmosphere. This reduction in pressure acting on the lower face of the plunger when it engages the member 16 provides a rapid downward movement of the plunger.

Abstract: 568,836. Inductance and capacitance measurements. WESSELY, K. Oct. 27, 1943, No. 17701. [Class 37] Apparatus for the measurement of inductances and capacitances comprises an oscillator A supplying oscillations of fixed frequency to a circuit comprising a standard inductance D which is tuned to resonance by a variable condenser C when this is at its maximum value, resonance being indicated by a valve voltmeter B. A condenser whose capacitance is to be measured is connected to terminals G, E so that it is in parallel with the condenser C. The value of this is then reduced by an amount equal to the capacitance under test in order to restore resonance, the amount of the reduction being indicated on a scale. An inductance of a value higher than the inductance D is measured by connecting it between the terminals G, E and disconnecting the inductance D by opening a switch F. The circuit is again tuned to resonance and the value of the inductance is indicated on a second scale on the condenser C. An inductance smaller than the standard inductance D is measured by connecting it in series with the inductance D across terminals H, E with the switch F open and adjusting the circuit to resonance. The unknown inductance is then the difference between the measured value and the inductance D and is indicated on a third scale on the condenser C.
