A spool 113 of the valve has two lands 114, 115 and is biased by springs 122, 123 to a central position in which gaps 116, 117 connect a reservoir line 207 to both circuit lines 205, 206. When the pressure in the line 205 (or 206) exceeds the pressure in the other line 206 (or 205) the valve spool 113 moves left (or right) against its spring bias to close the connection between the reservoir line 207 and the high pressure line 205 (or 206) and increase the connection between the reservoir line 207 and the low pressure line 206 (or 205). The movement of the valve spool 113 is normally limited by stops 120a, 121a. If the pressure in the high pressure line 205 (or 206) exceeds a predetermined value the spring bias of the stop 121a (or 120a) is overcome to permit further leftward (or rightward) movement of the valve spool 113 to a position in which the reservoir line 207 is connected to both the low and high pressure lines 205, 206 and thus acts as a relief valve. In Fig. 5 (not shown) the valve spool is divided between the lands 114, 115 and a spring is interposed between the lands.

Abstract: 917,580. Phase comparators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 24, 1961 [Dec. 16, 1960], No. 42111/61. Class 40 (5). In a circuit to compare the phase of a sawtooth and a square wave, a PNP transistor 41 and an NPN transistor 40 have their collectors connected together to receive the sawtooth wave 43 applied at 24, and their emitters connected together to a load R, the square wave being applied directly at 34 to one base, and after inversion being applied at 32 to the other base, so that if the square wave arrives before the saw-tooth reaches a given value (which may be zero volts-the median value of the saw-tooth) one transistor conducts, and if it arrives after this time the other transistor conducts, the voltages developed across the load R being opposite in the two eases. In effect, the saw-tooth voltage is sampled by the square wave pulses, a capacitor 50 in parallel with the load resistor R, being charged to the sampled value, and discharged via R when the sampling pulses cease. The circuit output at 29 may be used to control the frequency of a clock-pulse generator in a data processing system in accordance with the rate at which characters are read from a tape. Specification 902,163 is referred to.

Abstract: 961,498. Feeding webs. PACKAGE MACHINERY CO. Nov. 9, 1962 [Nov. 13, 1961], No. 42419/62. Heading B6B. [Also in Division B8] A wrapping-machine, particularly intended for wrapping sliced loaves, has a web supply system where web W from a roll R passes around a slackener roller 670 on an arm 672, over a table 676 and thence between intermittent feed rollers 684, 686 to a web plate 592. When roll R is exhausted arm 672 falls to actuate a switch 777 which stops the motion of at least elevator 48. Also the trailing end of the web is brought to rest on table 676 by a brake 776 so that the leading edge of a web from a second roll R<SP>1</SP> can be easily spliced thereto. A third roll Rb may be used to supply a narrower band B of wax paper or other heat-softenable or sealable material which passes over a heated platten before being brought to adhere to web W. If band B is not required a table 784 and brake 786 are used instead of table 676 and brake 776. Of the intermittent feed rollers 684, 686, Fig. 30, the latter is powerdriven and the former comprises individual rubber rollers and is held in operative position by a toggle linkage of which links 710 are adjustable in length and is raisable on arms 704 by means of a handle 718. The intermittent functioning of the rollers depends on the length of web draped around slackener rollers 688, 690. When this length attains a given maximum roller 684 is spaced slightly from roller 686 by means of a solenoid 728 which is energized by movement of arm 742 and consequent closure of an electric circuit. Similarly, feed of the web is resumed when the length of web decreases to a given minimum. Means, including a blade 740, are described which prevent wrapping of the web around roller 686. Specification 834,725 is referred to.
