Title: Improvements in or relating to the manufacture of moulding dies and like pressing tools
Inventor: MATTHEWS STANLEY
IPC: B21D37/20
Filed: 1954-04-29
Abstract: A moulding die or like pressing tool comprises a cone portion and a harder facing moulded on the core portion which facing is composed of an inert metal powder and/or mineral filler and a synthetic resin binding agent.  The die is formed by the following process.  A plaster mould is made from a pattern of the article to be pressed, which may be a master metal panel or a clay prototype and which may represent either the outside surface of the article or the inside surface, in which latter case it may be covered with a layer of wax or metal equal to the thickness of the desired article.  The inner surface of the plaster mould is greased and a layer of plaster applied to all vertical faces equal in thickness to that of the intended facing, which thickness is adapted to the work for which the die is required.  The core portion of the die may then be moulded, which is done by filling the mould with a mixture of filler, e.g., sand, synthetic resin, e.g., an epoxide resin, and a catalyst or hardening agent and allowing the resin to cure.  Concrete is also mentioned as a suitable material for the core.  If the die is intended to be bolted in position, e.g., to a punch, plaster inserts are suitably located in the mould and removed after the curing, leaving holes corresponding to the positions of the bolt holes.  The cured core is removed from the mould and the layer of plaster is stripped from the mould and a silicone release agent applied.  The core is then suspended in the mould with clearance determined vertically by how far it is lowered and horizontally by the plaster layer and the clearance space is filled with a mixture of epoxide resin and hardening agent and a filler of cast iron powder, cast aluminium powder or aluminium silicate.  If bolt cavities have been moulded in the core they are filled with a mixture, e.g. of epoxide resin and aluminium silicate.  When the resin has cured the finished die consisting of the core and hard facing is removed from the plaster mould and the cured insert material is drilled and tapped to receive bolts.

Title: Improvements in or relating to doffing mechanism for spinning, twisting and like machines
IPC: D01H9/04
Filed: 1924-05-24
Abstract: 228,846. Schneider, H. Feb. 5, 1924, [Convention date]. Doffing-arrangements; spindle and lifting rails; spindle apparatus; spindle-driving apparatus.- Relates to spinning, twisting, and like machines, particularly flyer frames having detachable duplicate interchangeable bobbin rails, as described in Specification 13128/11. Guide rails b, Fig. 1, are mounted independently of the ordinary standards a and carry a bracket carrier c for the bobbin rail and a slide d for doffing purposes, which are provided with racks and pinions l, m for effecting the building and doffing operations. The guide-rails are H shape in cross-section, as shown in Fig. 4, so that the carriers and slides are accommodated in the opposite grooves, or they may be tubular. The slide d carries a horizontally-movable carrier e provided with noses r, q, which serve properly to position the bobbin rails g, g<1> for the doffing and restarting operations. In frames having a single line of flyers, the slide d is raised and lowered, and the carrier e moved so that the rail g with the full bobbins is removed from its supporting pins p and the rail g<1> with the empty bobbins is placed thereon, and, after the full bobbins are removed, the rail g is placed in the position occupied by the rail g<1> in Fig. 1. In frames having two staggered rows of flyers, the path of movement of the bobbins during the doffing and restarting operations is of the form of an inverted T, as shown in Fig. 10; in this case the carrier c only is movable vertically, the carriage e being arranged on a stationary bracket o, Fig. 6. A hinged rail k is used for aligning the flyer legs. When the flyers are electrically driven by motors supplied with current from the rotor of a slipring asynchronous generator, which acts as a converter and is driven by a motor, they may be rotated for winding a. few turns on the empty bobbins by exciting the stator of the generator, the motor not being started. If the frequency of the supply is too high or the mass of the converter too great, the driving-motor may be started so as to drive the generator and then cut-out and the generator excitation switched-in, whereby fewer turns are wound on the empty bobbins. The number of turns may be further controlled by the bearing of the thread that extends from the full bobbin upon the lower flange of the empty bobbin, whereby the bobbin is forced against the drag washer. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement to diminish the drag when starting. A bar c<1>, Fig. 12 (Cancelled), is moved so that an incline b<1> thereon operates a pin a<1> and raises the bobbin tube u from the drag washer z. The pin may be arranged to work in an axial hole in the spindle t and engage a cap v on the bobbin tube. The bars c<1> may be moved by electromagnets energized by the doffing-mechanism. This subject-matter does not appear in the Specification as accepted, and forms the subject-matter of Specification 229,696.

[Class 40 (v)] A system for determining the direction of an object from a transmitting station comprises an equi-signal beacon at the transmitting station, means for turning the beacon about an axis, a receiver responsive to the radiation reflected by the object and including means for deter. mining the orientation of the transmitter for which the receiver response is equal for the two signals. In the described embodiment, the transmitter comprises a pair of antenna and reflector units 5<1> 5<11>, Fig. 2, set at an angle and rotatable together to produce a pair of overlapping beams having characteristic modulation frequencies of w1 and w2 respectively, the reflected wave being received by a similar rotatable unit. After rectification at 66 the modulation components are separated by a filter 67 and separately rectified at 68, 69 to give D.C. outputs which are applied to circuits 70, 71 in such a way as to produce currents proportional respectively to the difference and the sum of the signals. These are fed to relays 73, 74 arranged so that a signal is recorded on an indicator 76 only when the difference is zero and the sum is of substantial value. The orientation of the transmitter at this instant gives the direction of the reflecting object. Instead of using a rotating antenna, the overlapping beams may be produced by successively energized antennµ as described in Specification 526,658. Specification 580,975 also is referred to.

Title: An improved process for obtaining volatile metals
IPC: C22B19/04
Filed: 1934-11-21
Abstract: In a process for recovering zinc and other volatile metals from oxide ores and the like by reduction with carbon monoxide, the products of the reduction are passed through carbonaceous material heated to about 1000-1100 DEG  C. and the resulting carbon monoxide is returned to the reducing chamber with or without the addition of further gaseous fuel.  The gases from the carbon chamber are cooled to about 800 DEG  C. for the deposition of any sublimed lead and sulphides before being passed to a condenser for the deposition of the zinc &c., and thence to the reducing chamber.  The solid residues together with the deposited lead and sulphides are removed from the carbon chamber and replaced.  The charge of ore &c. may contain also some carbonaceous material, or loosening material such as lumps of chamotte or coke.  Some of the carbon monoxide obtained by the treatment of the carbon dioxide may be used for heating one or other of the chambers, and the waste gases may be used for drying or preheating the charge.

Abstract: 1,213,717. Controlled rectifier turn off circuits. COMPAGNIE GENERALE D'ELECTRONIQUE INDUSTRIELLE LEPAUTE. 15 March, 1968, No. 12826/68. Heading H2F. [Also in Division H3] In apparatus including a controlled rectifier (not shown) and a pulse generating circuit capable of being triggered by a timing pulse applied to a gate electrode 13 of a pulse generating controlled rectifier 10 to provide an output voltage to extinguish the controlled rectifier, a capacitor 4 has a D.C. resistive charging circuit 1-3, the time constant of which is larger than the period of the output voltage, and a discharge circuit having a definite free oscillation period, formed by the pulse generating rectifier 10 shunted by an oppositely and directly connected diode 14 and connected in series with an inductance 7, the pulse generating circuit being so dimensioned that its free oscillation period is substantially equal to four times the duration of the unipolar output pulse required for extinction of the controlled rectifier and the inductance 7 forms the primary winding of a transformer 8 the secondary winding 9 of which is connected to the first mentioned controlled rectifier (not shown). The anode and cathode of the controlled rectifier to be turned off is connected across 17, 18. When the supply 1, 2 is connected capacitor 4 charges via resistor 3 and the controlled rectifier 10 is then switched on by a timing pulse applied at 13. This discharges the capacitor 4 through the winding 7 to produce a turn off pulse (7, Fig. 2, not shown), in the output winding 9. The capacitor 4 and winding 7 then resonate so as to cause the capacitor to charge negatively until the rectifier 10 turns off. The diode 14 then allows the capacitor to discharge and charge positively (g) until the diode 14 cuts off. The output pulse (V s ) produced has a first turn off portion (t 1 -t 2 ), a second portion (t 2 -t 4 ) which would turn on the rectifier being controlled if its control electrode was energized and a third turn off portion (t 4 -t 5 ). The initial unipolar portion (f) (t 1 -t 2 ) of the output pulse may be greater than the period required for de-energization of the controlled rectifier connected at 17, 18. The controlled rectifier connected at 17, 18 may be a thyristor and may be used in A.C. to D.C. or D.C. to A.C. converter or for frequency changers for speed control of A.C. motors.
