Abstract: 834,560. Knitting. NEBEL, M. May 2, 1956 [May 2, 1955], No. 13615/56. Class 74 (2). The reinforced sole and heel or high heel of a circularly knitted stocking are formed of substantially double-length loops A, B, each drawn from the threads a, b forming two consecutive courses of the adjoining fabric, these loops being arranged in partial courses of which two correspond to one course outside the reinforced area, the loops in alternate partial courses being drawn in alternate wales only and the loops in the intervening partial courses being drawn in the intervening wales only. The reinforced area may be fashioned. Auxiliary jacks T<SP>1</SP>, with butts at two different levels, are provided to cause the needles to perform their desired movements. The hooks of those needles which do not knit in any partial course follow path X, thereby cleaving their old loops below their latches and taking yarn, but not knocking over. They remain sufficiently low for that yarn to stay on their open latches; and, in the next partial course, they again take yarn and then form loops from it and the yarn on their latches, moving down the path y to knockover portions. The additional yarn necessary for the formation of the double-length loops is provided by drawing yarn over the upper surfaces Po of the sinker hooks Px, the sinkers being advanced sooner and further than normally, and being selected through pattern jacks M.

Title: Rotary fluid pressure devices
IPC: F01C1/10
Filed: 1966-03-29
Abstract: 1,145,723. Fluid regulation. CHAR-LYNN CO. March 29, 1966 [July 9, 1965], No. 13956/66. Heading G3H. [Also in Divisions B1 and F1] A rotary positive-displacement pump, or motor, comprises an externally-toothed piston or star member 16, Figs. 1 and 8, meshing with an internally-toothed ring-number 6 having a greater number of teeth, a plurality of working chambers or cells 36----41 being periodically and sequentially connected to an inlet port 74 for the working fluid and one or both of two outlet ports 75, 76 for said fluid by a rotary valve-element 24 containing a co-axial stationary valve-element 28, and the star member being coupled to the element 24 by a shaft 50 having a universal joint at either end. A plurality of passages 86 in sections 2, 4 of an immovable casing connects said chambers to radial ports with which two sets of passages 84, 85, Fig. 7, are cyclically brought into register when the element 24 revolves. The passages 84 communicate with an annular channel 78 in the section 2, which channel is connected to the inlet port, and the passages 85 are cyclically brought into register with two sets of passages 94, 95 in the element 28, the passages 94 being connected to the port 75 by an annular channel 98 in the element 28, passages 88 in the element 24 and an annular channel 79 in the section 2, and the passages 95 being connected to the port 76 by an axial bore 30 in the element 28. To effect direction of the fluid from the chambers aforesaid to one or both of the outlet ports, the angular position of the element 28 relative to the ports associated with the passages 86 is changed accordingly by rotation of a knob 72, which is coupled to the element in question by gearing 68, 70. The power-output of the star member in the machine shown is used solely to drive the valve element 24, and therefore the machine functions as a flow distributer or divider. One of the outlet ports may be connected to a low-pressure reservoir (not shown) as that the pressure of fluid passing through the other outlet port is boosted by energy obtained by the star member from the fluid flowing to said reservoir. The star member may be connected to an external power-output, or input, shaft (not shown) so that the machine can operate as a pump or a motor. To effect flow integration, the ports 75, 76 are used as inlet ports and the port 74 becomes a common outlet-port. To prevent jarring due to fluid being trapped in the working chamber on the output side of the star member while for the time being they are disconnected from the outlet ports, by-pass passages 89 extend between the passages 85, 88, each of the passages 89 being furnished with a non-return valve 90.

Title: Method of and Apparatus for Reducing the Bubble Pulse from Underwater Explosions and Pressure Impulses
IPC: G01V1/387
Filed: 1968-03-22
Abstract: 1,168,947. Seismic exploration charges. BOLT BERANEK & NEWMAN Inc. 22 March, 1968 [22 March, 1967], No. 14039/68. Heading F3A. [Also in Division H4] To eliminate secondary pulses due to the bubble generated by actuating a seismic source in a liquid, collapse of the bubble is prevented by introducing within the bubble during its expansion gas at a rate insufficient to generate a shock wave and in a sufficient quantity to produce within the bubble at its maximum size a pressure substantially equal to the hydrostatic pressure outside the bubble. The source may be of the pneumatic, hydraulic, electromagnetic, spark, exploding wire or exploding gas type. In the Fig. 1 embodiment the source comprises a charge 4 of fast propellant or high explosive in a thin-walled plastic tube 3 which will not attenuate the primary pulse, and electrically detonatable initiating charge 1. A deflagrating slow charge 6 in plastic tube 5 is initiated with or after charge 4 and provides the gas to prevent bubble collapse. The weight ratio of charges 4 and 6 is selected according to charge composition and hydrostatic pressure. For use 35 feet underwater, charge 1 may be five grains of PETN, charges 4 and 6 may be respectively a smokeless pistol powder propellant and black powder in pellet form (in 1:1 weight ratio). Alternatively charges 4 and 6 may be TNT and smokeless powder in a 1: 2 weight ratio. In a second embodiment a volatilizable solid or liquid material (e.g. CCl 3 F) in a black polyethylene tube surrounds a number six detonator and transmits the detonator shock wave substantially unattenuated. The tube ensures heat transfer from the detonation to volatilize the material and so provide gas to prevent bubble collapse. In a third embodiment the primary shock wave is generated by a detonator and ruptures a pressurized condensible-gas cartridge (e.g. containing CO 2 ).

Patent GB-634369-A (GB)
Title: Improvements in or relating to apparatus for selecting electrical impulse trains
IPC: H04L17/30
Filed: 1946-05-09
Abstract: 634,369. Electric selective signalling systems. SADIR-CARPENTIER. May 9, 1946, No. 14077. Convention date, May 23, 1945. [Class 40 (i)] [Also in Group XL (b)] A receiver for a telegraph code employing for each character or the like a combination of impulses of two kinds, the number of each kind being fixed, comprises for each character a pair of delay lines, means for applying received impulse trains to one delay line, means for deriving complementary impulse trains in which e.g. marks are replaced by spaces and vice versa, means for applying these complementary trains to the second delay line and a threshold-responsive device connected to taps on both delay lines so positioned that sufficient voltage to operate the device is supplied only for the particular character to be selected. Let us suppose that a threshold relay device 8, Fig. 2, which may be electronic, is required to be operated by the particular signal of Fig. 1a, which is of the type comprising four marks and four spaces, and by no other signal. The signal is received at terminal T, squared at S, and fed to a delay-line 1 which is terminated by its characteristic impedance 2 to prevent end reflection. The line is divided into seven sections by eight taps I ... VIII and the delay of each section is equal to the length of a mark, or space: The taps corresponding to marks in the signal, i.e. I, II, IV and VI are connected by resistors 6 to the relay device 8. Thus, when the first signal impulse reaches tap VIII the remaining impulses will have reached taps I ... VII respectively and there will be a mark, or positive voltage, across each resistor 6. The incoming signal is also fed via a phaseinverter 4 to a second delay line 3 in which the " spacing " taps III, V, VII and VIII are connected via resistors 6 to the relay device 8. Positive voltages will therefore be developed across each of these resistors 6 at the same time as the voltages developed at the first delayline 1. Thus the correct signal will produce a positive voltage at each of eight taps, and the total voltage is sufficient to operate the threshold relay device 8. An incorrect signal will produce zero (or negative) voltage on at least one resistor 6 and fail to operate the relay 8. A similar circuit arrangement is provided for each signal combination which it is desired to receive, but the eight resistors 6 are connected in each case in a manner to correspond with the desired signal. The operation of the relay-device 8 may perform a desired telecontrol operation or signalling function.

Title: An improved apparatus for supplying liquid to zeolite water softening apparatus, sand filters and the like
IPC: C02F1/42
Filed: 1932-05-19
Abstract: 403,676. Softening water ; fluidactuated valves. WEBB, F. R., 448, 4th Avenue, New York, U.S.A. May 19, 1932, No. 14235. [Class 46.] Apparatus for automatically and periodically supplying liquid to water-softening apparatus, filters and the like comprises a valve member 30 movement whereof operates a piston 2 sliding in a cylinder r 1 mounted in a casing 4 and having radial ports 1d adapted to be in or out of register with ports 2e in the piston leading to a central bore 2b and to an outlet 4b. The casing is connected to liquid supply at 4a and to a closed air vessel by a terminal 4c, so that, with continued supply of liquid, the pressure on the valve member 30 increases until it is great enough to move the valve member 30 and consequently the piston 2, as against a spring 3, to a position wherein the liquid can pass through ports 1d, 2e to the outlet 4b. When the discharge takes place, the pressure decreases until the spring 3 forces the piston back into a closed position when the pressure proceeds to be built up again for the next discharge. The valve member 30 may be formed as the head of the piston 2 and may be provided with a differential seating 2G to which liquid is admitted under the air pressure through a port 8a in a plug 8 seated in a cap 1b on the end of the cylinder. As the seating 2G moves down, a greater cross-sectional area is exposed and the movement of the piston is thereby accelerated. This acceleration may be assisted by a radial port 1a in the cylinder, whereby liquid is delivered to the operative side of the valve member 30 when this has moved down sufficiently. The port 8a may be constricted by a screwed adjusting pin 10 so that the time of return of the piston may be adjusted. Bores 2a may be provided in the valve member 30 or a clearance provided between the piston and the cylinder in order to facilitate operation. The bores 2a may be restricted, or a ripple 2f provided so as to increase the downward force on the piston. The seating 2G may be eliminated and the bores 2a may then communicate direct with the bore 2b, or the seating may be formed on the cap 1b. The apparatus may be placed on the main inlet pipe of water-softening apparatus to provide a periodic flow therethrough or through an associated salt container in addition for regeneration. The closed air vessel may initially be charged with air to a pressure of 15 lbs. per sq. in. above atmospheric by communication with an air cushion at the head of the softening chamber and formed therein by the service pressure during a previous operation. Specification 161,641, [Class 26, Closets &c.], is referred to.
