Title: Method of measuring the windup weight per unit area of a moving  stretchable material
IPC: G01N9/24
Filed: 1974-07-10
Abstract: 1451551 Measuring weight per unit area by radiation gauge MEASUREX CORP 10 July 1974 [12 July 1973] 30565/74 Heading G1A The weight per unit area of a moving stretchable web of material held under tension between rolls 2-3, and winding reel 28, is measured at the location of the reel by calculation from the value of the weight per unit area or thickness at location 26 and the speed and/or width of the material at both locations. Measurement of weight per unit area by a radiation gauge 27 of the absorption measurement type which is scanned across the width of the web, is carried out at location 27 so that it is nearer to the point at which feedback control is applied, which would not be accurate if the measurement were made at the winding position. The width of the strip is measured by a photo-electric sensing apparatus forming part of the gauge 27 and using a light path which is interrupted by the edge of the strip, the travel of the apparatus between the two edges being indicative of the width. The speed of the web is measured by tachometer coupled to the idler wheel 26. Alternatively, the gauge 27 is a pneumatic device.

Title: Tool equipment for electro-hydraulic forming machines
IPC: B21D26/12
Filed: 1965-07-20
Abstract: 1,086,395. Stamping. BROWN, BOVERI & CIE, A.G. July 20, 1965 [Sept. 22, 1964; Nov. 18, 1964], No. 30839/65. Heading B3Q. [Also in Division H1] An electro-hydraulic forming machine comprises a cylinder 2 for receiving the die 5 and absorbing the forming forces, a head 3, 7 sealed on the cylinder at each end and electrodes 12, 13 passing through each head to form a sparkgap in liquid contained in the workpiece 6. Insulating and sealing members 8, 4 are arranged beneath the heads 3, 7, further insulators 17, 20 isolating rigid conductors 18, 21 from the head 7 and a table 1 respectively. Water from a pipe 22 is introduced without filling the chamber 14 completely, and is withdrawn after the forming operation. A pressure gauge measures the gas, e.g. air, pressure above the water. Pneumatic cylinders 15, 16 retract the electrodes, further cylinders 9 raise the head 7, and another cylinder 24 transfers the head 3, cylinder 2 and the die assembly laterally from beneath head 7 for removal and replacement of the formed work or the die. The machine may be operated automatically and/or manually. If the water level in the chamber is arranged to be below the top of the die, the die is made of an insulating material at that level or is coated with an insulating layer. Conical or flat electrode seatings (Figs. 2 and 3) are provided on the conductors 18, 21, and the seatings may be screw-threaded for adjustment in the conductors. A drain duct 27 is formed in the table 1. One or both heads 3, 7 may be made of insulating material, e.g. a synthetic resin. In various modifications, the electrodes may be fixed to movable conductors and the top head also fixed to the top conductor. The assembly may be screened electrically, mechanically and acoustically. The head 3 and cylinder 2 may be formed integrally. If the electrode 13 is fixed conductively to the head 7, the head should be insulated from the cylinder, but it need not be if the fixture is insulative. The electrodes may slide on the conductors, and hydraulic or electric drives may be used instead of pneumatic cylinders. The parts of a multi-part workpiece may be insulated from each other.

Title: Improvements in electrolytic cells
IPC: C25C7/08
Filed: 1952-12-05
Abstract: 730,057. Electrolytic cells for the production of refractory metals. TITAN CO., Inc. Dec 5, 1952 [Dec. 11, 1951], No. 30971/52. Class 41 An electrolytic cell for the production of refractory metals is characterized by means for stripping from the cathode within the cell, by relative movement between the means and the cathode, metal loosely deposited on the cathode and by means for removing the metal from the cell without exposing the metal to the atmosphere, both such means being operable from outside the cell. An apparatus which may be used for the production of titanium metal from titanium tetrachloride, comprises a line of identical cells, one of which is shown in Fig. 2. A well B formed by refractory blocks 15 in a steel casing 10, has cathodes 39, which may be nickel or tantalum tubes, and an anode 49. The cathodes and anode are separated by a vertical gas barrier 26 of refractory material. Electrolyte 52, comprising fused alkali or alkaline earth metal halides, such as a eutectic mixture of sodium chloride and strontium or magnesium chloride is heated by graphite electrodes 53. Each cathode is surrounded at the'lower end by a ring 43 (see Fig. 4), of metal such as nickel, provided with rod 44 extending through a cover-plate above the cathode. Titanium tetrachloride vapour is passed into the cell through the hollow cathodes and titanium metal deposited on the cathodes, chlorine being removed from above the anode by a tube 48. After certain intervals the rings 43 are moved down into engagement with the titanium metal; which is stripped off and falls into a basket 36 beneath the cathodes. The basket 36 is withdrawn upwardly in an inclined passage 29 in the side of the cell, by means of a handle 37 extending through coverplate 32. An air-lock type gate 35 is opened and the titanium tipped out of the basket into the bottom of a chamber formed by casing 33. The titanium cools in the chamber without being exposed to the atmosphere, arid, after the gate 35 is closed, is removed through a door 34. In a modification, instead of a line of cells side by side, a single long cell is used having cathodes arranged in groups and a gas barrier extending the length of the cell.

Title: Hinge fitting for adjustable back rests, especially for the seats of motor vehicles
IPC: B60N2/225
Filed: 1961-08-28
Abstract: 991,621. Hinges. W. PUTSCH, L. PUTSCH, F. W. PUTSCH, and U. PUTSCH, [trading as F. KEIPER [firm of]]. Aug. 28, 1961 [Dec. 27, 1960], No. 30981/61. Heading E2F. [Also in Division A4] A hinge fitting for the adjustable back rest of a motor vehicle seat comprises a pair of hinge parts 11, 12 pivoted together on a pin 16 and urged towards a forward position by a spring 26. The hinge part 12 carries a toothed segment 28 meshed with a pinion 31 rotatably mounted on the hinge part 11, and a toothed wheel 33 rigidly connected with the pinion is adapted to be engaged and locked by a toothed locking lever 34 freely rotatable on the pin 16 and actuated by a hand lever 37 through a pin and slot connection 40, 41. The hand lever, which is pivoted to the hinge part 11 by a pin 42, has a further pin and slot connection 45, 46 with a control lever 35 pivoted at 47 to the part 11 and provided with a nose 48 adapted to co-operate with a bevel 49 and notch 50 formed in a locking member 36. The locking member is freely pivoted on the pin 16 and has a guide track 52 engaged by an eccentric bolt 53 mounted in the hinge part 12. When it is desired to move the seat back into its forward position to give access to the rear seats of the vehicle the hand lever 37 is raised, thereby lifting the locking lever 34 clear of the toothed wheel 33 and the nose 48 of the control lever 35 clear of the bevel 49 so that the hinge part 12 is free to turn under the influence of the spring 26. In the forward position the eccentric bolt 53 is in engagement with the left hand end of the guide track 52 and the nose 48 is urged against the bevel 49 by a spring 43 which biases the hand lever 37 in an anticlockwise direction. When the seat back is subsequently raised the hinge part 12 first moves without the locking member 36, which is held by the friction between the nose 48 and the bevel 49, but the locking member begins to move as soon as the bolt 53 abuts the right hand end of the guide track. The back is turned until it reaches the "normal" or driving position corresponding to Figure 1, when the nose 48 drops into the notch 50 and allows the locking lever 34 to re-engage the toothed wheel 33 thereby locking the back in this position. Once free of the control lever 35 the locking member 36 turns under the influence of a spring 64 until the left hand end of the guide track abuts the bolt 53. The construction of the hinge fitting is therefore such that the seat back automatically locks in the "normal" position when it is raised from its forward tilted position but can be locked in a range of other positions by releasing the hand lever 37 and turning the back by hand to the required position before re-locking. The eccentric bolt 53 is adapted to be held in various angular positions in the hinge part 12 to adjust the "normal" position of the seat back.
