Filed: 1950-06-22
Abstract: 674,559. Tanks. PRELOAD ENTERPRISES, Inc. June 22, 1950, No. 15642/50. Class 69 (i) [Also in Groups X and XXVIII] A radially and axially reinforced hollow cylindrical concrete structure, e.g. a tank, comprises a hollow cylindrical concrete base member 12 with a tensioned reinforcing material 13 forming a series of helices on the outer surface, some of the helices sloping in one direction, and some in the opposite direction at substantially the same angle, to provide both radial and axial reinforcement. The reinforcing material itself may be coated with material such as asphalt before its application to the base, or an outer coating 14 of concrete, asphalt, &c. may be applied. The figures show a pipe construction which has an attachment collar 11 with circumferential reinforcement 16, and additional reinforcement may extend from the collar into the upper part of the section. The steel wire 13 may be wound in the form of a continuous double helix in which the wire progresses continuously round the structure and continuously from the top and bottom and back, and a series of lugs 17 may be formed in the base member during casting to act as anchors for the wire at the points where it changes direction. To apply the wire, the base section or the wire applying means is rotated and one or the other moved longitudinally. The wire is preferably wound at an angle of 15‹-30‹ to a plane perpendicular to the axis of the pipe.

[Class 79 (v)] [Also in Group XXXIV] In a truck, trolley or the like having a chassis supported at one end on a through axle carrying wheels steerable by steering arms and a trackrod connected to a draw-bar, lowering of the draw-bar applies a brake to the wheel through the track-rod. The non-rotatable wheel hub assembly 13 is steerably mounted at 14 on the through axle 11 which is provided with spring supports 12 for the front end of the chassis of a trolley which may be such as described in Specification 544,077, [Group XXXII]. A brake shoe 16 pivoted at 18 on a bracket 19 bolted to the non-rotatable hub assembly 13 extends over the brake drum 17 of the wheel and has integral therewith a steering arm 15 disposed in the horizontal plane of the axle 11. Guides 21 for the vertical movement of the shoe and arm about the pivot 18 are formed on a bracket 22 bolted to the hub assembly, a spring 23 for disengaging the shoe being carried by the bracket. A draw-bar is horizontally pivoted at 26 to a member 25 which is vertically pivoted at 24 to the axle 11 and to which the track-rod is 28 pivoted by a fork 29 embracing a bush 31 slidable on a pivot 32. The draw-bar thus effects steering movement of the wheels and by engagement with a projection 33 on the rod 28 when it is lowered it applies the shoes 16 to the brake drums.

[Also in Group XXXVI[ A trolley wire installation, more especially for tunnels and subways is suspended from at least one support element of cable form consisting wholly of glass fibres impregnated with a thermo-setting synthetic resin. The support element consists of a central core 1 surrounded by a plurality of strands 2 and is covered with a protective coating of rubber 3. The cable 1, 2 is impregnated with a thermo-setting synthetic resin which is polymerized in vacuum at a temperature of from 80‹ to 120‹ C. The trolley wire 21 is suspended by slings 5 also of glass fibre treated as previously described. The ends 10, 11 of the sling 5 are inserted in opposite ends of a tube 8 and are held therein by a filler and by indents impressed on the side of the tube 8. The ends of the tube 8 are funnel-shaped to prevent fraying of the sling 5. A hemispherical bowl 15 suspended by supports 14 from a roller 13 engaging the tube 8, shields the sling 5 from the electric field of the trolley wire 21.

Title: Improvements in or relating to electric signal transmission systems
IPC: H01J43/02
Filed: 1942-11-16
Abstract: 559,907. Two-way transmission; automatic volume control; thermionic modulation. WESTERN ELECTRIC CO., Inc. Nov. 16, 1942, No. 16178. Convention date, Dec. 9, 1941. [Class 40 (iv)] [Also in Group XL] The tube described in Specification 547,193, [Group XL], in which primary electrons pass through a window in the anode of a triode portion and are deflected through a collectorgrid to a secondary-emission anode is used as a switch in signal transmission circuits or as a modulator or volume controlling device. The tube may be modified by the provision of two sets of secondary electrodes at opposite sides supplied with primary electrons by a common triode portion. Two-way transmission.-The space between the secondary electrodes 10<SP>1</SP>, 11<SP>1</SP>, Fig. 10 is normally non-conducting. On the application of a suitable potential to the triode grid 14 over switch 66 (which may be speech-controlled) secondary emission takes place and the signal transmission circuit is effectively completed. Incoming signals may be applied to the grid 14 to produce a regenerative effect but the gain cannot be increased above zero without instability. In modifications, Figs. 11, 12 (not shown), the tube is brought to its conducting and non-conducting conditions by pulses of opposite sign over the transmission circuit or over a separate pilot current. As shown in Fig. 13, the tube has a second set of secondary electrodes and when an enabling pulse is received over circuit 88, a secondary discharge takes place between electrodes 10<SP>11</SP>, 11<SP>11</SP> and the potential of the triode grids is so modified that the discharge and a corresponding discharge between electrodes 10<SP>1</SP>, 11<SP>1</SP> in the transmission circuit persist. Thermionic modulation.-In the circuit shown in Fig. 10, unmodulated waves may be supplied at one side, modulating waves being applied to grid 14. Modulated waves then appear at the other side. The Specification as open to inspection under Sect. 91 comprises also the following :-(1) Preventing interference by static.-As shown in Fig. 14 (Cancelled), the secondary emission tube 20 is in the main signal path and is normally in its conducting condition. The arrival of an abnormally strong signal, however, renders it temporarily non-conducting. (2) Volume range compression and expansion.-If in the circuit shown in Fig. 14 (Cancelled) the valve 98 is normally just biased to cut-off and the grid 14 of tube 20 has variable-Á properties, the circuit would act as a volume range compressor. By the addition of a tube to reverse the phase of the control signal the circuit could be modified to act as an expander. This subject-matter does not appear in the Specification as accepted.
