Title: Improvements in and relating to pottery making apparatus and method
Inventor: DOVEY WALTER PHILIP
IPC: B28B5/02
Filed: 1967-02-16
Abstract: 1,146,234. Making pottery. WILLIAM BOULTON Ltd. 13 May, 1968 [16 Feb., 1967], No. 7476/67. Heading B5A. A method of making pottery comprises the steps of successively indexing a plurality of moulds 28, resting in mould supports 20 carried by an endless conveyer in a succession of intermittent short movements through a horizontal path past a die member 52 (which may be rotatable and may be heated) and a drying cabinet 12, raising and rotating each mould 28 in turn as it is indexed into alignment with the die member 52 and while it is stationary in the path so that the die member 52 and the mould 28 co-operate to form an article in the mould and then lowering the mould before the next indexing along the path. The indexing mechanism shown in Fig. 3 operates to drive shaft 16 and chain sprocket 14 attached to the shaft 16 and hence to drive the endless conveyer. Hydraulic pressure is supplied to cylinder 44 so that piston-rod 42 reciprocates. On each inward stroke of the piston-rod 42 crank 38 is turned about pivot pin 40 so as to slide pawl 46 into engagement with a slot 34 in the rotatable wheel 32, so that wheel 32 is indexed clockwise on each inward stroke. On each outward stroke the crank 38 is turned in the opposite direction to retract pawl 46 from a slot 34 and wheel 32 remains stationary. The mould 28 is raised by raising the jigger cup 58 until it engages, lifts and rotates each collar 24 in the mould supports in turn. The shaft which supports the jigger cup 58 has driving and braking plates mounted normal to its axis, the shaft being movable axially through them so that a radially extending plate on the shaft moves into frictional engagement with the driving plate when the shaft is raised and into frictional engagement with the braking plate when the shaft is lowered.

Title: Improvements relating to liquid measuring and dispensing apparatus
IPC: B67D7/30
Filed: 1939-03-09
Abstract: 526,136. Dispensing liquids. AVERY-HARDOLL, Ltd., and FRASER, J. March 9, 1939, No. 7586. [Class 166] Liquid measuring and dispensing apparatus of the kind in which means under the control of the operator serves to initiate the cutting-off of the supply under the control of the indicating mechanism comprises a flow valve unit located In the line of flow, retaining means which normally prevents a closing movement of the unit and means under the control of the operator for creating a momentary reverse flow in the delivery line and thereby releasing the said retaining means. Between the pump and the delivery nozzle is a housing 6 having an inlet 6a and an outlet 6b between which is mounted a flow valve unit comprising an annular member 7, valve rod 8, cut-off valve 9 and flow control valve 10. The member 7 is normally retained in its lower position by a weighted latch 26 which may be released by a downward movement of a piston 23 in a byepass 6e. In addition to the usual valve operated by a lever 29, the delivery nozzle A includes an annular piston valve 31 with a gapped skirt 31a and with an auxiliary valve 33 normally closed by a relatively strong spring 34. In operation, the pressure of the liquid opens the valve 10 and delivery proceeds until the operator depresses a lever 35 to close the valve 31. This causes a sudden stoppage resulting in a temporary opening of the valve 33. After release of the lever 35, the piston valve rises and the valve 33 is closed by its spring, the result being a momentary reverse flow to the housing 6. The reverse flow depresses the piston 23 and releases the catch 26 from the member 7 so that when the valve 31 is fully opened and the normal flow resumed, the flow valve unit rises until brought to rest by the engagement of the valve stem 9a with an arm 15 which is coupled to a trigger arm 19 carrying a pawl 20 co-operating with a cam 21 rotated by the indicating mechanism. When a flat 21a of the cam is presented to the pawl, the arm 15 is allowed to rise and the valve 9 closes to cut off the supply of liquid to the delivery nozzle. In a modification the piston 23 operates in a chamber carried at the lower end of a valve rod 8 which has a bore communicating between the chamber and the outlet 6b. The latch is mounted on a depending part of the member 7 and normally co-operates with an internal shoulder of the housing 6. In another form, Fig. 3, the lower end of a member 7 carries an inverted V-shaped tube containing a ball 42 which normally rests partly within a recess 71 in the housing 6 to prevent movement of the valve unit. The momentary reverse flow causes liquid to enter a passage 7h and groove 7k to drive the ball into the position shown in dotted lines. Specification 524,570 is referred to.

Title: Improvements in or relating to electro-magnetically operated disc clutches or brakes
IPC: F16D27/108
Filed: 1962-02-27
Abstract: 973,229. Friction clutches; operating clutches; electromagnetic brakes. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Feb. 27, 1962 [March 7, 1961], No. 7695/62. Headings F2C, F2E and F2L. A spring-engaged electromagnetically disengaged friction clutch or brake between a shaft 1 and a gear-wheel 21 for use in machine tool change-speed gears comprises rollers 29 housed in apertures 28 in cages 27, with their axes inclined to a radius and engaging frictionally between interleaved clutch discs 16, 26, splined to the shaft and gear-wheel, so that a part sliding and part rolling motion of the rollers with respect thereto takes place, the discs being arranged outside the effective magnetic field. As shown, a stationary magnet body 2 and coil 3, connected to a housing (not shown) and journalled at 4 on the shaft 1, rotatably carry a disc comprising a non-magnetic ring 9 radially sandwiched between ferromagnetic rings 8, 10 forming part of the magnetic flux path. A flange 14 fast with a clutch body 12 keyed on the shaft 1 axially supports the clutch discs against the engaging thrust of helical springs 20 acting through a pressure plate 17, which also serves as the magnet armature for disengagement. In Fig. 3 (not shown) the magnet body and coil are keyed fast to the shaft and the helical engaging springs are replaced by a single Belleville type plate spring. In addition, passages are provided through the shaft and clutch body to feed air or liquid coolant and/or lubricant to the friction surfaces. If used as a dry clutch with air cooling, the rollers are steel and the discs are of sintered bronze or provided with asbestos facings. In each arrangement, disengagement is by energizing the coil with direct current for a short period up to saturation point so that the residual magnetism becomes greater than the spring force and maintains disengagement of the clutch, without current, engagement thereafter being effected by supplying alternating current or by a counter-impulse to nullify the residual effect. The residual magnetism may be increased by having both the armature and magnet body made of permanent magnet material or by disposing bar-shaped elements of such material in structural parts of the flux circuit. Additionally, the clutch may have a limit-switch adapted to control the energization of the magnet coil and operated by the armature during displacement thereof or a temperature dependent impulse member by means of which the energization of the coil can be controlled in dependence on an operating magnitude or factor for example, the temperature of the magnet coil during energization thereof such that the magnetic force produced by partial energization in conjunction with the residual force is greater than the spring force.

Title: Improved drive device for rotating a bar to be twisted
IPC: C21D7/10
Filed: 1959-03-10
Abstract: 847,999. Twisting. UNION SIDERURGIQUE DU NORD DE LA FRANCE PAR ABREVIATION UNISOR. March 10, 1959 [March 12, 1958], No. 8252/59. Class 83 (4). A device for rotating a bar to be twisted is characterized in that the chuck, or other rotary device, for rotating the bar carries an element which is movable along the axis of the chuck and is combined with a switch controlling the starting-up of the driving-motor, said element being returned by elasticallyyieldable means in the direction which ensures the opening of the switch and being so disposed as to be depressed in opposition to the action of the yieldable means by the bar at the end of its introduction into said chuck, whereby the switch is automatically closed. A bar 1 to be twisted is held at one end in a non-rotary clamp 2 and moved axially into a chuck 3 of the self-gripping type. The end of the bar 1 moves a rod 13 in the chuck 3 axially back against a spring 15 to close a switch 13 which in turn closes a switch 11 to start an electric motor M to rotate the chuck 3 and twist the bar 1. The motor M is stopped automatically by a cam 33, 34, driven thereby, closing a switch 32 in turn opening a switch 12. A revolution counter could be used to replace this stopping means. In a modification, Fig. 3, a short rod 13a closes a circuit across terminals 37, 38 connected through rings 43, 44 and brushes 47, 48 to a switch 11 which is thus closed to start the motor. In machines in which the bar is introduced radially into the chuck a bellcrank is disposed therein to transmit axial movement to the push-rod.

IPC: H02P23/00
Filed: 1953-03-25
Abstract: 777,422. Automatic speed control systems. ROLLS-ROYCE, Ltd. March 23, 1954 [March 25, 1953], No. 8324/53. Class 38 (4). The speed of e.g. a gas turbine is controlled by a torque motor having a wound rotor and stator, supplied from a turbine driven alternator, and having a resonant circuit connected to the rotor or stator. Acceleration compensation may be provided. As shown, the alternator 10 supplies the stator and rotor coils 14, 16 of the torque motor device, and a series resonant circuit 18 is connected in series with the rotor. Movement of the rotor acts through linkage 31, 32 to operate a valve 33 controlling an oil pressure -operated piston 35 which (i) adjusts the fuel supply to the turbine through linkage 37, (ii) repositions the stator of the torque valve, and (iii) repositions the valve 33. Acceleration control is provided by a flywheel squirrelcage induction motor 38 also supplied from the alternator 10. Change in frequency causes stator reaction on the motor 38 to operate the valve 33 through linkage 40. Alternative arrangements.-(i) The stator coils of the torque motor 13 may be fed from tappings on the alternator (as shown by dotted lines 15A) to compensate for lack of phase quadrature due to iron losses in the torque motor; (ii) The rotor winding 16 may be energized by induction from the stator, Fig. 2 (not shown); (iii) a parallel resonant circuit may be used instead of the series type, Fig. 4 (not shown); (iv) a pair of valves such as 33 may be moved in opposite directions by the torque motor to control a differential oil pressure operated, Fig. 6 (not shown); (v) It is stated that the acceleration control may be effected by varying, e.g. the inductance in the resonant circuit instead of acting on the valve 33. Specification 777,423 is referred to.
