Title: Improvements in the manufacture of piston rings
IPC: F16J9/26
Filed: 1954-10-27
Abstract: 760,298. Making piston rings. BANQUAREL, A. L., and METALES Y PLATERIA RIBERA SOC. ANON. Oct. 27, 1954 [Nov. 4, 1953], No. 31045/54. Class 83 (2). [Also in Group XXVI] A method of making a composite piston ring having a body of cast-iron and a sliding surface of anti-friction metal comprises the following steps: making a ring of cast-iron in a mould, machining the outer surface of the ring, applying to the ring a coating of anti-friction metal, heat-treating the composite ring so formed in a furnace with a controlled temperature and atmosphere, and machining the composite ring to the desired size. The anti-friction metal, which may be bronze, copper, or leadcopper alloy, may be applied by spraying or by a powder metallurgical method. For ensuring the adhesion of the two metals there may be provided on the periphery of the cast-iron ring dovetail grooves which are filled with the anti-friction coating metal. The machining operations comprise grinding the sliding surface and slotting the ring. A number of castiron rings may be stacked into a cylindrical pile for the coating process. The inside of the cast-iron ring may also be coated with antifriction metal.

Title: Improvements in or relating to the control of valves in gulley emptying apparatus incorporating a vacuum chamber
IPC: E03F7/10
Filed: 1937-11-12
Abstract: 509,496. Gulley-emptying apparatus; valves. DEIGHTON'S PATENT FLUE & TUBE CO., Ltd., and RIDDELL, L. H. Nov. 12, 1937, No. 31065. [Class 135] [Also in Group XXXII] In gulley-emptying apparatus of the kind in which the contents of the gulley are sucked up by vacuum created in the sludge tank (not shown) of the apparatus, the inlet valve 3, Fig. 1, in the suction pipe 2 leading to the sludge tank is actuated by the vacuum in said tank. The valve 3 is mounted on a rock shaft 5 which is connected by arms and side rods to a crosshead 8 on the outer end of a rod 9 of a piston 10 which is disposed within a cylinder 11 associated with the casing 1 of said valve and may be spring loaded at 12. The piston is actuated by a slide valve 13, Fig. 6, which is housed in a cylinder 14 provided with a port 18 communicating with the sludge tank, atmospheric ports 17, and ports 15, 16 leading to the forward and rear ends of the cylinder 11. The slide valve 13 is loaded by a spring 19, located in one end of the cylinder 14, and is connected by a link 20 to a bell-crank lever 21 whereby it is connected preferably to a remote control e.g., on the suction pipe 2. The arrangement is such that, with the slide valve 13 in the position shown and the ports 15, 16 open to vacuum and atmosphere respectively, operation of the lever 21 at the remote point causes the slide valve to move axially against the spring 19 to reverse the functions of the ports 15, 16 and effect movement of the piston 10 to open the valve 3, this valve remaining open until the lever 21 is released. In a modification employing a rotary valve, the piston rod 9 terminates in a rack bar which meshes with a toothed quadrant on the actuating shaft of the valve. When it is desired to empty or partly empty the sludge tank by the application of pressure, the valve 3 may be opened by the vacuum in a tank which is superimposed on the sludge tank and is in communication therewith except when the latter is under pressure. Alternatively the valve is actuated by the pressure in the sludge tank, the slide valve 13, Fig. 7, being provided with an auxiliary valve 26 which automatically reverses the inlet and exhaust port connections 15, 16 to the cylinder 14 when a change is made from vacuum to pressure working. The valve 26 is slidably mounted in a cylinder 27, having ports 28 common with the cylinder 14, and is subjected at one end to atmospheric pressure, and at the other end to the vacuum or pressure in the sludge tank, the valve being provided with annular grooves, cooperating with the cylinder ports 17, 18 of the slide valve 13, and its cylinder 27 with supply. ports 28. This arrangement is such that the valve 26 will assume one extreme end position or the other, according, to whether there is vacuum or pressure in the sludge tank, and will change automatically the connections between the ports 15, 16 and ports 17, 17, 18.

Title: Improvements in or relating to starting apparatus for internal combustion engines
IPC: F02N15/02
Filed: 1934-10-30
Abstract: 434,248. Turning-gear. BOSCH AKT.- GES., R., 4, Militõrstrasse, Stuttgart, Germany. Oct. 30, 1934, No. 31066. Convention date, Nov. 4, 1933. [Class 7 (v)] In an electric starter in which a starter pinion 4 is connected by a light friction clutch to a starter shaft 1 displaceable axially to engage the pinion with the engine fly-wheel 20, a multiple-disc clutch between the pinion and the shaft is operative only when the pinion has entered some distance into mesh with the fly-wheel teeth. In one form, Fig. 1, the pinion 4 is integral with a sleeve 3 held against axial movement relative to the armature shaft 1. Threaded at 5 on the sleeve 3 is a nut 6 forming part of a multiple-disc clutch, the shell 8 of which is keyed on the shaft 1. One of the clutch discs 10 connected with the shell 8 has lugs 16 normally bearing against an annular disc 18 on the casing of the starter, the distance alpha from the clutch plates to the pressure plate 13 being greater than the distance # of the pinion 4 from the flywheel 20. At starting, axial movement of the armature brings the pinion 4 into mesh with the flywheel; when the armature has moved through the distance alpha, the pinion is partly in mesh and the lugs 16 are sufficiently far from the disc 18 to allow the clutch plates to be tightened on the pressure plate 13 by the axial movement of the nut 6 on the thread 5. If the teeth clash, torque is transmitted only through the clutch plates to the left of the disc 18 until the pinion is turned into meshing position. In a modification. Fig. 3, the friction disc 25, which preferably has a cylindrical flange, is held against the flange 15 of the nut 6 by a spring 26 bearing against an abutment 27 on the shell 8. If the teeth of the pinion clash with those of the flywheel, torque is transmitted only through the flange 15 and disc 25.

Title: Improvements in and relating to cyclotrons
IPC: H05H13/00
Filed: 1939-11-30
Abstract: 533,823. Cyclotrons. AKT.-GES. BROWN, BOVERI, & CIE. Nov. 30, 1939, No. 31171. Convention date, Dec. 5, 1938. [Class 39 (i)] In a cyclotron the increase in mass of the charge carriers due to velocity increase at very high velocity is compensated by increasing the electric field at the outer side of the cyclotron, so that the velocity of the carriers is increased, but the time of revolution is maintained constant. This is effected by applying an alternating voltage to semi-annular channels 1-12 which are insulated from each other and capacity-coupled, so that the maximum voltage applied to the inner channels 6, 7 &c. is progressively less than that applied to the outer channels. These are arranged above and below the vacuum space a wherein the electrons follow a spiral path and from which they finally issue to a discharge channel 19, being guided by a deflector plate 18.

Abstract: 632,279. Fire alarms. P.E.C.O. (ELECTRICAL CONTRACTORS), Ltd., and REECE, M. P. Nov. 25, 1947, No. 31185. [Class 47 (i)] [Also in Group XXXVIII] A fire alarm operated by the temperature of the surrounding air comprises a detector 1 consisting of a loosely-wound resistance-coil a and a closely-wound and insulated resistance coil d arranged in parallel with one another and each in series with a coil e or f of a relay 51 controlling a movable contact 11 which cooperates with fixed contacts g, h to operate a lamp 61 and, through a relay 12, a bell 81. A number of detectors 1 may be arranged with their coils a, d separately in series. The coils e, f of the relay 51 are balanced by a potentiometer R<SP>1</SP>, but are unbalanced, upon a rapid rise in temperature, by changes in the resistances a, d, and, upon a slow rise in temperature, by a resistance b in series with the resistance a and normally short-circuited by a wire c connected by an easily fusible alloy 6. The system is automatically re-set due to a resistance R2 arranged across the coil f being thrown into circuit by a contact 14 closed by the relay 12. For testing the system, a two-way switch 23 may be provided which normally completes the circuit between the resistance R<SP>2</SP> and the point 24, but when switched over, puts the potentiometer R<SP>1</SP> in shunt with the coil e to upset the balance. A fault is indicated by a lamp 18 and, through a relay 19, a buzzer 21, controlled by a switch 17, closed by a relay 15 when the current therethrough falls below a predetermined value.

Title: Regenerative Direct Current Motor Control having Field and Armature Control

Filed: 1969-06-21
Abstract: 1,199,270. Control of D.C. motors. WEB PRESS ENG. Inc. 21 June, 1969, No. 31477/69. Heading H2J. [Also in Division G3] To start a D.C. motor 22, a source 30 is adjusted to provide a reversible signal, representing the desired speed, which turns on either rectifiers 44, 46, or 48, 50, in circuit with field winding 26. Firing circuit 52 receives a feedback signal through conductor 43 whereby the field current corresponds with the signal in conductor 40. A signal representing the field current is passed through conductor 68 and amplifier 201 to firing circuit 64 associated with rectifier bridge 62 in circuit with the armature 24. Tachometer generator 34 provides feedback to reduce the signal in conductor 40, so reducing the field and armature currents. Amplifier 201 receives the field current signal in conductor 68 and an armature current feedback signal in conductor 70 so that the field and armature currents are proportional to each other and the motor has a series characteristic. When the reference signal is reduced, or the motor is overhauled, the signal in conductor 40 changes sign to reverse the field current and the counter E.M.F. of the armature. The signal in conductor 68 correspondingly decreases and then increases, so causing regenerative operation through the rectifier bridge 62. If the signal in conductor 40 becomes excessive during either motoring or regenerative operation, the firing circuit 52 becomes saturated to limit the field current. This leads to a consequential limitation of the armature current.

Abstract: 1402644 Change-speed control NISSAN MOTOR CO Ltd 6 July 1972 [26 Nov 1971] 31741/72 Heading F2D In an automotive automatic transmission the level of servo pressure actuating a ratioselecting (e.g. second ratio) brake 18 is reduced upon entry into that ratio by fluid pressure supplied from the usual shift valve 14 through a branch 138 to act downwards on the usual main pressure regulator 12, the pressure supplied the branch 138 being the same pressure as that, 68, supplied to actuate the shift-valve 14, rather than, as in existing arrangements (Fig. 1, not shown), a pressure supplied through the shift-valve after the latter has been actuated. This avoids the time lag present in the said existing systems and ensures that the regulator valve 12 reduces system pressure before application of the brake 18 is started by the pressure 64 supplied through the actuated shift-valve, resulting in a smoother shift. On brake engagement the pressure reduction reacts back on the regulator 12 through the conduit 138, thus reducing regulator load and decreasing regulated pressure which however remains below that before shift. In a shift involving disengagement of the brake, the action is reversed and the final pressure after shift is greater than that before. In Fig. 5, the spring-returned shift-valve 14 is depressed, to pressurize the brake servo line 64, by de-energizing a solenoid 88, causing closure of an exhaust valve 86, which permits build up of pressure 68, supplied above the shift-valve through a restrictor 74a from line 22a, this same pressure 68 passing through the branch 138 to the main pressure regulator 12. In this form the solenoid 88, together with that of a second shift-valve, are controlled electronically by output speed and engine-throttle sensors (Fig. 4, not shown), feeding comparator circuits. In a wholly hydraulic form, Fig. 7, not shown, the pressure 68, which depresses the shift-valve is supplied through a pilot valve subject to opposing fluid pressures responsive to output speed and engine intake depression.
