Abstract: 1,217,659. Press-brakes. VERSON ALLSTEEL PRESS CO. 18 Jan., 1968 [2 Oct., 1967], No. 21852/70. Divided out of 1,215,841. Heading B3E. [Also in Division F2] An input shaft 36 of a press-brake is driven through a flywheel 12 and a two-speed, direct/ reducing, gear controlled by mechanically or hydraulically operable clutches 40, 42. The gear comprises a casing adapted to be bolted at 122 to a press-brake drive system wall 120 and a driven sleeve 106 for receiving and keying to the shaft 36. In the electro-hydraulic control, of Fig. 2, for the gear and for a drum brake (not shown) connected to the press-brake shaft 36, a constant delivery, vane type, double pump 132 is driven by the flywheel 12, draws from a sump 130, and feeds a clutch lubricating line 166 and a line 135. The latter leads to a solenoidoperated valve 136 and, via a line 133, to a piston type relief valve 134 which when forced open feeds gear and bearing lubricating lines 100, 102, 116 (Fig. 1). A line 144 from the valve 136 feeds lines 148, 150 through a sequence valve 146. The line 148 is connected to actuate the clutches 40, 42 through a solenoid-operated Direct-Neutral-Reduced valve 152, and the line 150 branches to a spring-biased brake-release cylinder 170 and a solenoid-operated two-position brake cylinder-dump valve 174. In operation, with the valves positioned as shown, the valve 136 directs fluid to the lubricating lines 100, 102, 116 through a check valve 140, the cylinder 170 is spring-biased to station the pressbrake, and both clutches 40, 42 are disengaged. To actuate the press-brake, the valves 136, 174 are changed over. The sequence valve 146 first feeds the line 150, whereupon, with the dump valve 174 blocking, the cylinder 170 is pressurized to release the press brake. On application of sufficient pressure to the cylinder 170, the sequence valve 146 diverts flow to the line 148 so that, by way of selected operation of the valve 152, the gear establishing clutch 40 or 42 is engaged. On said changeover of the valve 136, feed to the lubricating lines 100, 102, 116 is temporarily halted until sufficient pressure in the line 133 opens the relief valve 134. (For Figures see next page.)

Patent GB-755071-A (GB)
Title: Process for the conversion of polyethylene terephthalate into dimethyl terephthalate
Filed: 1954-07-28
Abstract: Dimethyl terephthalate is obtained by heating polyethylene terephthalate to 220-245 DEG  C. in the presence of a transesterification catalyst, such as metaphosphoric acid or phosphoric acid, and superheated methanol vapour.  The catalyst is supported on carbon black or is sprayed continuously into the reaction chamber.  Alternatively the polyethylene terephthalate is admixed with terephthalic acid which serves as a catalyst support. The polyethylene terephthalate can be used in the form of threads, bristles or textile products.  The dimethyl terephthalate formed sublimes in a current of excess methanol vapour into a cooled receiver.  In the example, polyethylene terephthalate scrap is mixed with terephthalic acid and passed through a reaction chamber heated to 240 DEG  C., together with a stream of methanol vapour heated to 240-250 DEG  C.  Metaphosphoric acid is sprayed continuously into the reaction chamber.  The dimethyl terephthalate formed passes as a vapour through a layer of active carbon and thence to a cooled receiver.  Undistillable products and phosphoric acid esters are condensed immediately after passing through the active carbon layer and thus separated from the dimethyl terephthalate.  The crude product contains a small amount of the monomethyl ester.

Abstract: 1515853 Control systems for vehicle window demisters LUCAS ELECTRICAL Ltd 13 May 1975 [17 May 1974] 22107/74 Heading H2H The rear window demister of a road vehicle is controlled so as to be de-energized automatically when the engine coolant reaches a predetermined value. A demister 16 of a road vehicle is energized by closing an ignition switch 12 and moving a switch 38 to its first operative position 39 whereupon, with a cold engine coolant the potential at the junction of the coolant sensor 23 and gauge 22 is such that transistors 31, 33 are off and transistors 46, 59 are turned on, the turning on of transistor 59 causing energization of relay 18 to close contact 15. When the engine coolant temperature reaches a predetermined value the potential at the junction between the sensor 23 and gauge 22 is such that transistor 31 turns on thus turning on transistor 33 which latches on transistor 31. Transistors 46, 59, now turn off to de-energize relay 18, opening contact 15 to de-energize the demister 16. With the circuit in this condition the de-mister will remain de-energized whatever the water temperature. If at any time when the demister is de-energized, movement of the switch 38 to its second operative position 41-position 39 remaining energized-a transistor 56 turns on and hence transistor 59 thus again energizing the demister 16 whereupon the demister can only be de-energized by opening the ignition switch 12. The circuit cannot be latched during a warm-up period by virtue of a diode 54.
