Filed: 1964-09-17
Abstract: An alloy containing in percentage by weight: <TABS:1014438/C6-C7/1> is solution treated at 1600-2100  DEG C. for 5 minutes to 9 hours, and is subsequently treated at 1000-1500  DEG C., for 1/2 hour to 40 hours, the conditions of the second treatment being such that the metal recrystallizes.  Cooling at a rate such as 300  DEG C./min. from the solution treatment temperature down to 1200  DEG C. is preferable. An intermediate working step can be carried out between the two stages of heat treatment but deformation by cold work should not exceed 40%.  The alloys may be prepared by arc melting or by powder metallurgical methods.

Abstract: 963,705. Control systems for welding arcs. AIR REDUCTION CO. Inc. Nov. 11, 1960 [Nov. 13, 1959], No. 38796/60. Heading H2H. Re-ignition of the arc of an A.C. inert gas shielded welding system wherein a workpiece 7 is a poor thermionic emitter is achieved on each positive half-cycle of the alternating supply current from a generator 1 by an H.F. spark generator 10, the energy supply to which is controlled by a thyratron 18 whose control electrode 18b is under the influence of a potential compounded if the sum of two or three component potentials themselves dependent on circuit conditions. Full wire rectifier 64, 65 provides a negative bias potential from transformer 49, the supply 45 of which is independent of the welding supply 1. A second negative bias potential is -obtained from a rectifier 34 connected to the welding supply 1 by means of transformer 23. Positive cycles of the welding supply 1 derived from a potential divider 28, 29 connected to a further secondary winding on transformer 23 will try to ignite the thyratron against the compounded potentials of the two negative bias supplies, the second of which is adjusted by means of a variable resistor 35 so that ignition of the thyratron and hence spark initiation of the welding arc will only occur on the positive peaks of the sinusoidal welding supply. Under arcing conditions, the welding potential across 3, 9 will drop and thus reduce the second negative bias supply derived from it. Sharp peaks at both leading edges and trailing edges of the now generally square positive half-cycles of welding current are presented from igniting the thyratron on both these peaks by a circuit including neon tube 39 arranged to conduct on the trailing edge peaks and bias a diode 38 so that a low impedance shunt path is produced which presents them from reaching the thyratron control electrode. Re-ignition of the welding arc thus only occurs at the leading edge of the positive half-cycles of the welding current.

Abstract: 925,213. Cables. SCIPER S.A. Nov. 17, 1959 [Nov. 17, 1958], No. 38970/59. Class 36. [Also in Group V] A cable is enclosed within a flexible tube of impermeable, insulating plastic material having internally projecting, longitudinally extending ribs which locate the cable coaxially within the tube, the latter being reinforced, e.g. against internal fluid pressure, by a permeable sleeve embedded in it and through which the plastic material permeates. The sleeve may be of glass fibres. The cable so sheathed may be pressurized by liquid or gas which may also be used for cooling by circulation. The sheathed cable may be made by the apparatus of Fig. 1 by feeding the cable 2 and a woven sleeve 1 along a tube 5 provided with cone-shaped clamps 6, 8, 7 and 9 which may be released to enable the sleeve 1 to be corrugated to form a reservoir so that the correct rate of feed may be maintained when the cable and sleeve pass through a dryer 12 and extrusion head 13. Within the extrusion head (Fig. 3) the tube 5 terminates in a hollow mandrel 25 which supports the sleeve 1, and through which the cable 2 passes to the extrusion orifice. The mandrel terminates in a die 26 having a throat portion and axial grooves, the plastic material in the chamber 24 being forced through the woven sleeve into the throat and along the grooves so that as it emerges from the die it forms an internally ribbed tube 29 enclosing the cable and embedding the woven sleeve. Specification 856,955 is referred to.

Title: Improvements relating to the determination of the maximum consumption of electrical power
IPC: G01R21/00
Filed: 1963-10-04
Abstract: 1,025,708. Selective signalling. ZELLWEGER Ltd., FACTORIES FOR APPARATUS AND MACHINE USTER. Oct. 4, 1963 [Oct. 5, 1962; July 26, 1963], No. 39231/63. Heading G4H. [Also in Division G1] In a method and apparatus for determining the maximum electrical power taken by a consumer, the current taken forms several voltages proportional to itself, all with different factors of proportionality, and the voltages are applied to the contacts of a multipoint switch, the highest voltage being arranged to charge a storage capacitor until the charge reaches the threshold value of a breakthrough device, whereupon it discharges through an electromagnetic device which connects the next lowest voltage to the storage capacitor; in this way, the contact associated with the voltage which is just insufficient to charge the storage capacitor enough to re-actuate the electromagnetic device is a measure of the maximum power taken (assuming a constant voltage and power factor). As shown, Fig. 1, the current taken passes through the primary of a current transformer 2 whose secondary is shunted by a stepped resistor 4 having tappings a . . . h which supply progressively lower voltages to the contacts A . . . H of a multipoint switch 5. Switch arm 6 initially connects the voltage at A via a rectifier 7, a smoothing capacitor 8, and a limiting circuit 9, 10 to a storage capacitor 12. When the capacitor voltage Uc reaches the breakthrough value of a four-layered diode 13, an electromagnetic device 14 is energized to step switch-arm 6 on to contact B. Only when the current taken rises enough to produce at B a voltage sufficient to re-actuate 14 does the switch-arm move on to C, and so on. Each contact A ... H may be marked with the value of maximum current or power, or a counter 15 may be provided. The time constant of the charging circuit may be made variable by connecting a number of storage capacitors in parallel and providing a selector switch. Other breakthrough devices, e.g. glow discharge tubes, may be used instead of a four-layered diode. Fig. 3, not shown, depicts a three-phase supply, each phase line containing a resistor, the voltage across which is supplied to the primary of one of three transformers whose secondary voltages are rectified and connected in series across stepped resistor 4. In a modification (Fig. 4, not shown), the voltage developed across a resistor 41 in the supply line is fed to the primary of transformer 42, whose secondary is tapped at points a . . . g which are connected through proportioning resistors to contacts A . . . G of multipoint switch 5. The tapped voltage charges a screen capacitor 8; when the capacitor voltage reaches the breakthrough voltage of Zener diode 83, transistor 85 becomes conductive and capacitor 12 is charged. Zener diode 82 limits the voltage across the base-emitter path of the transistor, and the charging rate of capacitor 12 is held substantially constant.

Title: Vehicle hydraulic brake system
IPC: B60T8/50
Filed: 1974-09-10
Abstract: 1453739 Brake pressure modulation AISIN SEIKI KK 10 Sept 1974 [18 Sept 1973] 39351/74 Heading F2F In a hydraulic braking system a modulator 20 has a check valve to cut off pressure supply to slave brake cylinders and a piston to vary the volume and thus the pressure of a circuit including the slave cylinders, the modulator, in skid conditions, having a power member to move the piston to increase or decrease the volume at either of two rates, the faster rate being selected by a signal of short duration immediately after brake pedal release. The modulator 20 has a diaphragm on one side exposed to atmospheric pressure and on the other side to a passage 58. Upon receipt of a skid signal a valve member 45a is moved rightwardly by a solenoid 27a to stop communication between a vacuum source and the passage 58 and to connect the passage to atmospheric air in a chamber 61, causing movement of the power member, i.e. a diaphragm which moves the piston to allow a ball valve member of the check valve to cut off hydraulic flow to the wheel cylinders and to increase the volume of a chamber connected to the cylinders for pressure decrease. A further valve 28 of the modulator when closed causes air flow through a restriction 57a between the passage 58 and the valve member 45a, and upon receipt of a low road adhesion signal causes a valve member 46a carrying the restriction 57a to open to allow unrestricted flow for faster diaphragm operation for brake release and reapplication. A second diaphragm in tandem with the first diaphragm is spring biased to operate the piston and ball valve to allow full flow to the wheel cylinders if the vacuum source fails. In the circuit of Fig. 4, a switch 80 is closed upon receipt of a skid signal to operate the solenoid 27a. The solenoid 73 is operated for faster diaphragm operation either by closing of a switch 74 if a low adesion surface is detected, or by the combination of a closed switch 62, caused by seating of the ball valve during skid conditions, and a closed switch 78 caused by a relay 77 actuated by a discharging capacitor 76, charged upon brake pedal release by a switch 29 contacting a terminal B. This ensures that if the brake pedal is released during skid control, the diaphragm is actuated at the faster rate so that the ball valve is unseated rapidly in case of a necessary further brake application.
