Title: Improvements relating to flowmeters
IPC: G01F1/22
Filed: 1941-02-11
Abstract: 549,355. Flow meters. EVANS, C. H. Feb. 11, 1941, Nos. 1884 and 3713. [Class 69 (i)] In a flow meter for gases or liquids, a piston or float is adapted for movement in a vertical cavity of uniform cross section and has a depending rod or the like decreasing downwardly in cross section and extending through an orifice in a plate, the position in equilibrium of the piston &c. being determined by the pressure of the gas &c. flowing through the orifice. In its lowest position, the piston or float may rest on the orifice plate or inlet opening to act as a non-return valve. The tapered rod may be interchangeable and have uniform or varying taper ; it may be replaced by a closed aluminium &c. tube. In Fig. 1, the piston 2 moves in a cylinder 3 in a body 4 of ebonite, metal &c. and the tapered rod 1 depends through an orifice in a plate 5 interchangeably held by a threaded ring 18. Fluid enters by passage 7 and leaves by passage 9, and passages 15, 16, allow equalization of pressure. A disc 12 on the rod 1 moves against a scale 13 on or adjacent to a depending transparent tube 11 ; when measuring gases, the tube I may contain liquid, the disc 12 then having a damping effect. When measuring liquids, the outlet passage is carried upwards or is formed by the passage 15. In Fig. 2, the cylinder 3 is formed by a tube 21 within a cylindrical fitting 24, the fluid outlet being by passages 23, 25. In Fig. 3, the fluid enters at 7 and passes through the plate 5 and past a float 2 carrying the rod 1 and having inclined blades 27 whereby the fluid flow rotates the float ; the float 2 may be conical, the blades 27 being arranged so as not to extend beyond the greatest diameter of the float. The float moves in an opaque &c. tube 26 which holds the plate 5. The Provisional Specifications also describe (a) apparatus in which an upwardly tapering fluid inlet nozzle extends through the base of a vertical cavity surmounted by a glass cylinder held to the base by tension rods, and a conical float, which may be bladed to give rotation, has a depending cylindrical skirt surrounding the inlet nozzle, the entering fluid raising the float and escaping upwardly outside the skirt and piston, (b) apparatus in which a single transparent vertical tube is provided in which a rotatable, conical &c. float is raised by the entering fluid, a chain depending from the float, and the suspended part of the chain varying according to the pressure of the fluid, and (c) apparatus similar to that in (b) but with the chain replaced by a rod which depends into a liquid of desired specific gravity, the rod, if desired having a thin upper end, and a lower end of enlarged diameter.

Title: Improvements in d.c. amplifiers
IPC: H03F1/34

Abstract: 877,998. Transistor amplifying circuits. BECKMAN INSTRUMENTS Inc. Jan. 20, 1960 [April 27, 1959], No. 2044/60. Class 40(6) A D.C. amplifier comprises a forward path including a modulator 13, an isolating transformer 18 an A.C. amplifier 27 and a demodulator 25, and a negative feedback path from the output terminals 28, 29 including a modulator 34, an isolating transformer 35 and a demodulator 36. An integrater 30 may be connected in the forward path between the demodulator 25 and the output terminals, and the output terminals may be shunted by a capacitor 32. A transducer 10 has its output leads 11, 12 connected via a low pass filter 40, Fig. 2, to a four position switch 45, three positions of which give different amounts of feedback depending on the tapping of the contact 46 along the resistance chain 41, 42, 43, 44 and the fourth position shorts the input to the amplifier. The contact 47 of the switch is connected to the vibrating arm 14 of a chopper type modulator which has diodes 48, 49 to limit the voltage swing. The output from the chopper is fed through the double screened isolating transformer 18 into the A.C. amplifier 27 which comprises five push pull transistor stages the last of which is provided with a switch 66 for varying the gain. The output from the A.C. amplifier is fed via a phase sensitive demodulator 25 into the integrater, Fig. 3, which comprises a long tailed pair followed by a push pull stage and by two further stages each having a PNP and an NPN transistor, the final stage having its two transistors 86, 87 with their emitter collector, paths connected in series, diode clamps 88, 89 being connected to the base of transistor 87. The feedback capacitor 31 is connected between the output line 28 which is connected to the junction of the emitters of the transistors 86, 87 back to the input of the integrater. The isolating transformer 35 in the feedback path is also a double screened type and the output of the feedback path is developed across the resistor chain 41-44 and fedback into the input of amplifier. The isolating transformers allow the circuit to be used without either input leads 11 or 12 being connected to earth or to any other reference potential.

Title: Improvements in or relating to the treatment of dyeings for improving their fastness
IPC: D06P1/649
Filed: 1935-01-22
Abstract: Cellulose esters, dyeing.--The fastness, especially the fastness to acid gases, of dyeings on cellulose fatty acid ester artificial silk material is improved by treating the material with a semicarbazide, which may be added to the dyebath or may be incorporated in the material before or after dyeing.  In an example, acetate artificial silk, dyed with 1 : 4-di-(methylamino) anthraquinone, is treated for 20--30 minutes in a bath at 50--60 DEG  C. containing 3 grams per litre of phenylthiosemicarbazide and containing a dispersing agent, e.g. soap or a condensation product of a fatty alcohol with ethylene oxide or of a high molecular carboxylic acid with an amino- or hydroxy-sulphonic acid or of formaldehyde with a naphthalenesulphonic acid.

Filed: 1971-01-18
Abstract: 1292564 Inserting terminals in bobbin flanges; shearing AMP Inc 18 Jan 1971 [27 Jan 1970] 2331/71 Headings B3A and B3W Apparatus for assembling a component with a workpiece, e.g. a terminal 2 in a bobbin flange 10, comprises releasable means which move with a reciprocable feed device and hold a component severed from a strip of components during its travel towards the workpiece. A bobbin 4 is placed in a recess in a holder thereby actuating a control valve of a piston-cylinder unit 54. The piston-rod 56 drives a slide 38, Fig. 6, and a block 230, to which is resiliently secured a connecting rod 224. The rod 224 pivots a lever 216 to draw a bar 210 on to the bobbin flange 10. As the slide 38 moves forwardly, a camming block (170) secured thereto, Figs. 3, 4 (not shown), pivots a rod 160, Fig. 6, to straighten a toggle linkage, 138, 140. This action moves a bar 132 downwardly along with a plate 126, on which are mounted a shear member 90 and a block 118. A flange 114 on the member 90 co-operates with shearing edges of blocks 94, 102, to sever the leading terminals from their strips, which have been advanced by the slide 38. The block 118 clamps the severed terminals to the block 94 by means of fingers 124, which are mounted on a shaft 122 and biased by a spring 181. Further movement of the piston-rod 56 drives the terminals into the bobbin flange. On the return stroke of the rod, the fingers 124 are lifted off the terminals by camming surfaces engaging projections in slots 96, Fig. 10 (not shown), on their ends 172, and then the rod 160 actuates the toggle linkage to raise the shear block 90 and the fingers 124. An air jet removes the bobbin from the holder 26 thereby re-setting the actuating switch of the unit 54.

The rod then passes through a guide tube 22, where the surface and centre temperatures may equalize, and finally to a coiling device 12 where an atomized water spray completes the cooling to 900-1300 F. Specification 342,189 and U.S.A. Specification 2,658,012 are referred to.
