Title: Improvements in or relating to methods and devices for protecting reinforcing cablestensioned after hardening the concrete from corrosion
IPC: E04C5/12
Filed: 1952-11-21
Abstract: 721,517. Reinforced concrete. COYNE, A., and BELLIER, J. Nov. 21, 1952 [Dec. 19, 1951], No. 29485/52. Class 20 (4). Multi - strand steel wire cables used in the post-stressing of concrete structures are protected in situ against corrosion by filling the cable with a material such as pitch or bitumen, the wires at one or both ends of the cable being spread apart in a cone-like formation and the bitumen &c. being injected into the spread at one end so that it passes along the small ducts between the wires to the other end. Fig. 1 shows a cable located in a vertical bore or duct 1 which is accessible from the upper end only. The cable consists of a bundle of wires 2 which are spread and anchored at 3 at the lower end, the upper ends of the wires also being spread and embedded in an anchor block 4. The length of the spread at each end is limited by a binding 6 and the whole cable including the spread portions is bound with tarred fabric 7 to render it fluid-tight. The cable is tensioned by applying a tractive force to the block 4 and a tube 12 inserted axially into the cable so that its lower open end enters the spread portion, as shown in Fig. 3. The annular space around the cable is filled with grout through a pipe 14 and when this has set bitumen is forced down the pipe 12 to rise around the pipe and fill the small ducts between the wires. When an injection tube cannot be inserted through the cable, the bitumen may be injected through pipe 14 into the duct 1 to enter the lower spread portion of the cable from which the wrapping 7 has been omitted and rise up through the cable as shown in Fig. 6.

Title: Improvements in or relating to gating circuit arrangements
IPC: G11C19/00
Filed: 1958-09-16
Abstract: 895,677. Diode gating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 16, 1958 [Sept. 19, 1957], No. 29627/58. Class 40(6). A gating circuit which delivers at its output 2 a pulse of a predetermined polarity when there are simultaneously applied to the circuit an appropriate level of voltage at its input terminal 1 and a shift pulse of said predetermined polarity, comprises two seriesconnected diodes 7, 8 connected between the input and output terminals and poled so as both to conduct in the same direction and so that diode 7 allows the pulse of said predetermined polarity to pass to the output, the junction point of the diodes being connected to a bias source 12 in series with the source 13 of said shift pulses through the parallel combination of a resistor 14 and capacitor 15 and the junction point between the diode 7 and the output 2 being connected to a bias source 17 the arrangement being such that when the appropriate voltage level is applied at input 1, the application of a shift pulse causes the potential at point 16 so to alter as to cut off diode 8 and cause diode 7 to conduct whereby an output, having the same polarity as the shift pulse is delivered to output terminal 2. The circuit illustrated comprises two similar circuit branches, the lower one comprising diodes 20, 21 reversed in polarity with respect to diodes 7, 8 and having shift pulses of opposite polarity applied to the junction between these diodes; thus depending on the state of binary circuit 5 the simultaneous application of shift pulses from circuits 13, 26 causes either a positive or a negative pulse to be applied to terminal 2 to control the state of binary circuit 6. As described the circuit 5 has voltage output levels of +20 and +45 volts, batteries 12 and 30 supply 20 volts and batteries 17 and 25 supply 45 volts. The shift pulses have an amplitude of 10 volts. Hence when the voltage at terminal 1 is 45 volts that at points 16 and 29 is likewise 45 volts. The application of a positive pulse to point 16 causes diode 7 to conduct and a positive output pulse to pass to terminal 2 while the application of a 10-volt negative pulse to point 29 is insufficient to cause conduction in diode 20. When, however, the output level from circuit 5 is 20 volts, the application of a 10-volt positive pulse to point 16 is insufficient to cause conduction in diode 7 while the application of a negative pulse to point 29, which is also at 20 volts, causes conduction in diode 20 and the passage of a negative pulse to the output terminal 2. Specification 870,089 is referred to.

Abstract: 940,324. Automatic temperature control. ROBERTSHAW-FULTON CONTROLS CO. Aug. 29,1960 [Sept.11, 1959], No. 29735/60. Heading G3R. [ Also in Division F2] A burner fuel control system comprises a valve seat 82 controlled by a fuel valve 88 operated by a bimetal element 86 in response to intermittent energization of a heater 108 for the element where - by the opening of the valve is proportional to the period of energization. Space heating burner 12 is supplied with gas via manifold 10 and valve 36 operated through compound levers 54, 56 moved by thermal bellows 46 and phial 42 heated by pilot burner 16 ignited from continuously burning pilot 138. Gas for pilot 16 passes at 64 through valve seat 82 axially adjustable by knob 76 for setting the temperature of the heated space and is controlled by valve 88 actuated by bimetal 86 heated electrically by element 108 in series with heater 114, bimetal 116 actuating contacts 102, 122 in series with the heaters. Contact 122 is carried by a flexible spring 124 positioned by a rod and tube thermal element 128 detecting the space temperature. Initial rotation of knob 76 and cam 98 connects the heaters through switch 100 to the electric supply 102. The heater 108 opens valve 88 to supply gas to pilot 16 which heats mercury phial 42 and opens valve 36 to supply gas to burners 12 and heat the space. When element 128 is cold flexing contact 122 follows contact 120 and the contacts are only broken after a comparatively long period by bimetal 116 heated at 114. Thus at low space temperatures the heating periods are long and valve 88 opens wide to give a high pilot flame 16, a wide open valve 36 and a high flame at burner 12. As the space temperature approaches the set value element 120 moves spring 124 to the left, contacts 120, 122 break after a short interval of time and the heating periods of element 86 are reduced so that valve 88 opens only a small amount to give a reduced pilot flame and a reduced opening of valve 36 for a lower flame at burner 12.
