Title: Improvements in the manner of temperature regulation in the treatment of distillablecarbonaceous materials with hydrogenating gases
IPC: C10G1/06
Filed: 1937-07-15
Abstract: In the liquid phase treatment of distillable carbonaceous materials with hydrogenating gases at elevated pressures and at temperatures above 300 DEG  C., the temperature of the materials in the hydrogenation converter is regulated by withdrawing materials from the converter or the hot catchpot, cooling them to the required extent, and recycling them to the converter without substantial release of pressure.  The hydrogenation is preferably carried out in presence of catalysts which may be supported on carriers.  The degree of cooling effected may be controlled by varying the amount of the liquid recycled and/or the temperature to which it is cooled.  Ground coal is pasted with an equal amount of heavy oil obtained from a previous similar operation.  The paste mixed with 2 per cent iron sulphide is heated with 1,5 cubic metres of hydrogen per kilogram of paste in a preheater to 450 DEG  C. under 600 atmos. pressure and passed into a converter vessel maintained at 475 DEG  C.  The products obtained are passed into an adjacent catchpot from which heavy liquid products are withdrawn, cooled to 250 DEG  C., and recycled to the converter in the proportion of one kilogram of liquid product per kilogram coal introduced.  Specifications 392,631 and 476,744 are referred to.

Title: Starting means for a single-phase asynchronous el'ctric motor
IPC: H02P1/44
Filed: 1971-06-09
Abstract: 1358396 Control of A.C. motors DANFOSS AS 9 June 1971 [10 June 1970] 19699/71 Heading H2J  A control means, for a bi-directional semiconductor switch connected in series with a starting winding of a single phase asynchronous motor, includes a device that provides a voltage that decreases as the motor accelerates, and a capacitor, between the device and a control electrode of the switch, that charges in each cycle from the decreasing voltage, and discharges with a time constant sufficient to ensure that the switch is rendered conductive immediately following each starting winding current zero until the motor reaches a preset speed. As shown, a triac 7 in series with starting winding 4, is controlled by a circuit including capacitor 13, resistor 15 and transistor 16, the circuit being supplied from a tapping point 11 on a divider, comprising resistor 9 and a PTC resistor 10 connected across the motor supply 1 2 or in series with the motor winding 4. On starting, capacitor 13 charges on positive half cycles of the tapped voltage, and discharges via transistor 16, which is turned off when its base voltage falls below a threshold value, i.e. just before a first winding current zero until just after a subsequent current zero. Whenever transistor 16 is off, the voltage at 17 from capacitor 13 is applied to the trigger electrode 8 of triac 7 which can thus be triggered on immediately after the next winding current zero. As the motor speed increases and PTC resistor 10 warms up, the tapped voltage falls until insufficient to trigger triac 7 and the starting winding current ceases. In another embodiment, Fig. 3 (not shown), an alternative bias circuit of transistor 16 ensures that when the triac 7 is turned off, transistor 16 is turned on to prevent further excitation of the triac and thus prevent overload of the starting winding.

Title: Improvements relating to sliding windows for vehicles
IPC: E05F11/38
Filed: 1934-07-06
Abstract: 436,473. Sliding window &c. holders. SLEIGH, H. L., CHESTON, A. S., and STUART, F. J., Widney Works, Bagot Street, Birmingham. July 6, 1934, No. 19853. [Class 44] In holding devices for sliding windows for vehicles, relative movement is prevented between the two co-operating members of the device in a direction parallel with the plane of the window, to minimize wear, to ensure efficient operation of the holding means notwithstanding slight inaccuracy of fit in the usual guide channels, and to allow the holding means to be fitted during manufacture of the sliding window member. In Figs. 1, 4, the sliding window 1 has a frame the side members 2 of which have a channel extension 3 slidably embracing rack bars 6 with recesses 9. The bars 6 thus partake of lateral movements of window 1. The window is retained in adjusted position along the bars by a pair of oppositely directed bolts 10, housed in a part 11 of the upper horizontal frame member and projected outwardly into engagement with recesses 9 by a spring 14 disposed between operating finger-pieces 13 on the inner ends of the bolts. The rack bars are supported on the fixed guide channels 4 by pins 8 passing freely through slots 7 in the bars, or by pivots or other means allowing limited lateral movement of the bars. In alternative forms the rack &c. may be replaced by a chain and sprocket wheel. Figs. 7, 8 show the sprocket wheel 16 mounted on the sliding window 1. Engagement with chain 6 prevents lateral relative movement between the parts 1, 6, 16. The chain is supported by and has limited sliding movement on a pin 8 fixedly mounted on guide frame 5. In a modification the sprocket is carried by frame 5 and the chain is slidably supported on a pin carried by the frame of the sliding window.

[Also in Division E1] A freight car door comprises a plurality of interlocking extruded metal intermediate panels 36, Fig. 6, which also interlock with a top element 32 and a two-part box-like base element 34, and are connected by welding or rivets 84 to side elements 30. As shown in Fig. 8, each panel 36 has channel-shaped edge portions, the shapes at the joints between the panels being complementary. The panels on one side are substantially flat and one channel has the inner side of one side wall provided with a lip 52 having a convexly-shaped surface merging into an undercut or groove 54 and the other side wall 48 provided with an inwardly facing bead 50. The complementary channel is provided in one side wall with an external groove and a nose portion 56 whilst its other side wall 62 is plain. A panel is assembled to another panel or the top or the base element by partially engaging the nose 52 in the complementary groove with panels or the panel and element tilted with respect to each other. By relatively rotating the parts the outer end of the side wall 62 engages the bead 50 and snaps into interlocking engagement as shown, this engagement preventing relative rotation in the reverse direction. One or other of the parts 48, 62 yields slightly to permit the interlocking. The base element comprises a part having a base wall 66, Fig. 7, ribs 68, 72 and 76, and a flange extension 70 on the rib 68. This part interlocks with another part comprising a front panel 78, a flange 80 and an extension 82. The base element is connected to each side element 30 by a H-section connector 86. Another form of intermediate panel has edge portions as shown in Fig. 12, the channel of one edge portion having on one side wall 96 an inwardly facing lip 98 and a curved rib 100, whilst the other side wall 102 has a hookshaped end 104. The complementary channel has on one side an external groove 114 and an inwardly turned curved rib 112, whilst the other side has a ridge 120 and inclined abutment 106. In this form the interlocked channels form a box beam.
