Title: Improvements in or relating to power plant
Inventor: MORRIS ALBERTO JORGE
IPC: G05G15/00
Filed: 1960-11-18
Abstract: 926,941. Belt or chain tensioning devices. R. A. LISTER & CO. Ltd. Nov. 17, 1961 [Nov. 18, 1960], No. 39686/60. Class 80 (1). In a power plant comprising a combustion engine driving a load through belt or chain gearing, tension in the belt or chain is maintained by fluid pressure from a system associated with the engine. An internal-combustion engine drives a fan and a dynamo through a belt or a chain, tension in the driving means being varied by pivotal movement of the dynamo 13 under the action of a piston 11 and cylinder 10. The piston 11 is urged to tighten the belt by a spring 16 together with pressure oil, from the engine lubricating system, admitted to the cylinder through a non-return valve 15. When the belt breaks or becomes abnormally slack, the piston 11 moves to the left sufficiently to uncover an annular port 19, leading through passage 21 to the engine sump, and so decrease the oil pressure. A spring loaded latch 34 is held depressed by normal oil pressure in pipe 24, acting on piston 35, to hold a ring 32, attached to a rod 30, from moving under the action of a spring 33. On decrease in oil pressure the latch 34 is retracted by the spring 37 and spring 33 moves the rod 30 to contact a flange 39 on the fuel pump rack to stop the engine. A knob 30a is provided for starting and resetting purposes. In a first modification the oil pressure acts on a double spring-loaded piston assembly which automatically resets the rod 30 when the engine restarts and builds up oil pressure. In a second modification the oil pressure from the port 19 raises the latch to allow the rod 30 to stop the engine.

Title: Improvements in or relating to the trueing of profiled grinding wheels
IPC: B24B53/085
Filed: 1964-09-30
Abstract: 1,008,650. Grinding. HERBERT LINDNER G.m.b.H. & CO. Sept. 30, 1964 [Oct. 3, 1963], No. 39834/64. Heading B3D. A method of trueing a profiled grinding wheel 1 for generating a thread comprises moving a trueing diamond 3 in a path which is parallel to a rectilinear main flank line of the profile and inclined relative to the axis of symmetry of the profile, and generating the profile flanks by superimposing on said movement feeding movements at right angles to the main flank line. In a machine for carrying out the method, the profile is trued simultaneously by two diamonds 3, 4 connected to pistons 51 slidable in cylinders in holders 49, the movement of the pistons being in directions at right angles to the main flank lines. The holders 49 are carried by rods 34, 35 which are slidable in segments 71, 72 adjustable by worms 73, 74 so that the direction of movement of the holders is parallel to the main flank lines. The holders are formed with racks 32, 33 which engage separate gears 31, 31<SP>1</SP> rotatable about a common axis in opposite directions by gearing 28, 29, 29<SP>1</SP>, 30, 31<SP>1</SP> driven by the movement of a rack 27 on a holder 20 for a template 25. A pin 26 engages the template and is carried by a member 36 having two pistons 37, 38, each of which is connected by a separate line 42, 43, balancing cylinder 44, 45 and line 46, 47 to a space 48 in the cylinder of a tool holder 49. In operation, fluid pressure from a pump 62 is directed through a throttle valve 70 to a space 21 in a cylinder to move the holder 20 and template 25. the movement of the holder causes the gearing to move the rods 34, 35 upwardly so that the diamonds travel upwardly from the root to the crest of the profile. At the same time, fluid pressure is supplied by a line 64 to act on the pistons 37, 38 to urge the pin 26 against the template. As the pistons move inwardly under the control of the pin 26, the fluid pressure in the lines 42, 43, balancing cylinders 44, 45, and lines 46, 47 acts in the spaces 48 to move the diamonds 3, 4 at right angles to the main flank lines to form the profile on the grinding wheel. A counterpressure is supplied to the cylinders 20 and 48. At the end of the movement of the template holder 20, an abutment 54 actuates a switch 55 controlling electromagnetic reversing valves 56, 57 to reverse the fluid pressure connections so that the diamonds are withdrawn from the wheel and the template holder 20 and diamond holders 49 moved to their initial positions in which a further abutment 68 actuates a second switch 69 to reverse the valves 56, 57 for another truing operation.

Abstract: 1515920 Electrically operated stapler SWINGLINE INC 1 Oct 1975 [2 Oct 1974] 40115/75 Heading B4C An electrically operated stapler comprises a solenoid operated driven blade and this solenoid is powered with a plurality of pulses which are derived from alternate half cycles of an A.C. power source. A control circuit produces two pulses by defining a window by means of phase shift inputs to a Darlington transistor 57. This produces an enabling signal which allows the driver blade to be operated when switch 23 is manually actuated. Power for actuation is stored in a condenser 74 and values are chosen such that condenser 67 shuts off Darlington transistor 57 and condenser 74 retains charge sufficient only for required number of driving pulses. Switch 23 is either actuated by bar 26 as inserted material shifts trigger 32 or manually via switch 24 and bar 35. The stapler may be of a standard type.

Title: A device for measuring the level of a liquid
Inventor: COOPER LESLIE ALFRED GEORGE
IPC: G01F23/16
Filed: 1965-09-21
Abstract: 1,167,722. Liquid level indication. CASTROL Ltd. Dec.20, 1966 [Sept. 21, 1965], No.40204/65. Heading G1H. A device for measuring the level of a liquid in a vessel, such as the level of oil in the engine sump of a motor vehicle, comprises a tubular probe 6 with a restricted opening 16, the probe being so positioned that the opening is just submerged by the liquid when the liquid is at the desired level in the vessel, the probe also having a piston 15 slidable in the probe, a solenoid 1 for moving the piston within the probe so that gas or the liquid may be drawn into or expelled from the probe through the restricted opening, and means in the form of two switches 8, 9 for sensing the rate of movement of the piston so as to determine whether a gas or the liquid is passing through the constricted opening. In the embodiment described the restricted opening is provided by a ball valve 16 having a leak at its seating. In use the probe is inserted into the hole normally occupied by the dipstick in a motor vehicle with the side arm 7 outside the sump. The solenoid 1 is energized to raise a solenoid plunger 2, the piston 15 and a dash-pot plunger 11 Fig. 2 (not shown). Switch 8 is closed and switch 9 opened. If the level is low air will have been sucked into the probe so that when the solenoid is de-energized the piston returns to its lower rest position rapidly and switch 9 is closed by the solenoid plunger 2 returning to its lower position whereas switch 8 is still closed due to delay effected by the dash-pot. Since the switches are in circuit a signal is passed to operate the dispensing device to feed oil through tube 7, probe 6 and an opening 14 into the sump. When oil is drawn into the probe by raising the piston, the piston returns slowly to its rest position and switch 8 then opens before switch 9 is closed and a signal is sent to indicate that the oil is not below its correct level.

Abstract: 1,164,274. Protective arrangements. EPSYLON RESEARCH & DEVELOPMENT CO. 23 Sept., 1966 [23 Sept., 1965], No. 40537/65. Heading H2K. [Also in Division H3] An earth leakage protective arrangement comprises a core-balance transformer having a ring core surrounding line and neutral conductors of a supply circuit and a secondary winding 14 connected to a transistor circuit controlling the tripping of a circuit-breaker in the supply circuit. The transistor circuit may comprise complementary transistors 22, 23, the transistor 22 having its base connected to the secondary winding 14 and its collector to the base of the transistor 23. When the A.C. voltage induced in the winding 14 is sufficient, the transistor 22 conducts on a positive half cycle and renders the transistor 23 conducting. The resulting voltage across a resistor R 10  provides a feed-back through a diode 26 to the base of the transistor 22 to maintain the transistors conducting. The output from the transistor circuit is applied via a line 27 to a transistor power amplifying circuit effective to energize the trip coil of the circuit-breaker. This amplifying circuit may include a power transistor and a controlled rectifier. In another arrangement, Fig. 2 (not shown), the winding 14 is connected through a diode (16) to the emitter of a unijunction transistor (15) which controls the firing of a controlled rectifier (20) connected in series with the trip coil (19) of the circuit-breaker.

Abstract: 1408333 Spark erosion AEG-ELOTHERM GmbH 29 Aug 1973 [1 Sept 1972] 40584/73 Heading B3V [Also in Division G3] A spark erosion machine comprises a pulse generator 1 including a triggering voltage source U 1  and a machining voltage source U 2 , a detector circuit 5, 6, 7 connected across the machining gap 4 for accumulating peak values of the pulse triggering voltage applied across the gap 4, a circuit 8, 9 for forming a mean value signal U m  of the peak values, a comparator circuit 15 for delivering an output signal if the difference between the mean value and a reference value exceeds a predetermined amount and means for varying the flow rate of the dielectric through the gap 4, when an output signal from the circuit 15 occurs. The peak value of each generated machining pulse is transferred by a diode 5 to a capacitor 6 which then discharges through a resistor 7 when the spark discharge occurs. The capacitor 6 is recharged only if the peak voltage of the next pulse exceeds the voltage still present across the capacitor 6. The mean value U m  of a plurality of pulses is formed by a filter comprising a resistor 8 and a capacitor 9 and is passed via a resitor 12 into a comparator circuit 15. If the mean value signal, e.g. U mII  is lower than a reference voltage supplied by a potentiometer 11 indicative of contamination in the gap 4, a transistor 17 is triggered to switch on a warning lamp 20. The rate of flow of dielectric through the gap 4 is increased by the operator or, alternatively, the detector circuit automatically controls a valve in a dielectric pump and causes the gap 4 to be widened if the contamination in the gap 4 has not been removed after a time delay.
