Filed: 1944-08-20
Abstract: 587,175. Gauges. HOWELL, H., and RICHFIELD & SON, Ltd., T. Aug. 20, 1944, No 13941. [Class 106 (ii)] Conical surfaces are measured by a device comprising means for indicating relative displacement such as a dial gauge, a convex member adapted to contact the surface of the core at some distance from the apex, and a second member adapted to contact the object being measured at the same time and at a different distance from the apex, the two members being operatively connected to the relatively inovable parts of the dial gauge. The ring gauges 2, 8, Fig. 1, are secured to concentrically arranged holders 1, 7. A plunger 6 secured to the holder 7 can slide freely in the bore of a.plug 4 forming part of the body of a dial gauge 5 and located in an aperture in the holder 1. The gauging surfaces of both rings are finished to the same radius. A device for gauging internal tapers employs spaced gauging discs separated by a helical spring. In a modification of this device, each disc is replaced by three equi-spaced arms or two opposedarms. In the case of both external and internal gauges one gauge member may be adapted to abut a flange or shoulder on the object, the other gauge member only contacting the taper periphery. In Fig. 8, the spindle 22 having a taper A to be gauged is mounted on vee-blocks 24 on a bed-plate 23. The gauging device comprises a plate 26 supported from the bed-plate by balls and having,two sets of vertical gauging cylinders 29, 32. Both sets are mounted on transverse slides 28, 31 and the slides 31 are mounted on longitudinal slides 30. The spindle 13 of a dial gauge 5 mounted on a slide 31 abuts a slide 28. The diametral spacing of the gauging cylinders may be varied by the use of gauge blocks 33, 34.

Title: Separation of close boiling components by adsorption
Inventor: DILLMAN EDWARD ELIAS
IPC: B01D53/04
Filed: 1963-04-10
Abstract: 1,001,450. Separation of close boiling components in a mixture. ENGINEERS & FABRICATORS Inc. April 10, 1963, No. 14274/63 Heading B1L. Close boiling components in a mixture are separated by passing through an adsorbent which selectively adsorbs one of said components and thereafter regenerating the adsorbent by introducing a mixture of an inert gas and the adsorbed component. The components may be normal and non-normal hydrocarbons, e.g. n- and iso-hexane ; ethane and propane and heavier hydrocarbons while the inert gas may be hydrogen or helium but preferably nitrogen. A purge step may be operated wherein a mixture of the inert gas and the unadsorbable component is used to purge the adsorbent of the adsorbed component and thereafter passing a cooling gas. In a specific embodiment, four beds are used, corresponding to adsorption A, cooling C, purging P and regeneration R respectively, which are operated cyclically and successively in these capacities by means of valves A-1 to R-2. In the phase shown in the Figure the feed mixture is introduced at line 10 by means of pump 11 to valve 14 which controls the flow to either or both heat exchangers 16 and 17 prior to flowing through line 18 into tank 20. Vaporized feed from tank 20 flows through line 25 together with an inert gas, e.g. nitrogen, introduced at 18a or 45b to valve A-1 which has outlet 1 open. Adsorption bed A, e.g. a synthetic zeolite if n and iso-hexane are to be separated, receives the feed through line 26 and allows the effluent stream to pass through line 27 to valve A-2, which has port 1 open. Gas flows by line 28 through heat exchanger 16, condenser 29 to accumulator tank 30 whence liquid iso-hexane is discharged by line 32 to storage. The inert gas goes via line 33 to gas circulator 36 and on to lines 38 and 39. Valve C-1 has an inlet 38a and has port 2 open thus gas passes through line 40 to bed C to cool it. The effluent passes by line 41 and port 2 to valve C-2 and returns to circulator 36 by line 42 and heat exchanger 17. Inert gas enters the purge bed P by lines 39 and 43 after passing through port 3 of valve P-1 and is discharged through line 44 to valve P-2 via port 3 whence it passes to line 45 and on to heating coil 45b, to enter the vaporizing vessel 20 by line 45c. A nitrogen n-hexane mixture is withdrawn from tank 49 via line 50 and pump 51 and passed through line 52, heat exchanger 53 and heater 54 to valve R-1 whence it leaves by port 4 and flows through line 56 to the regeneration bed R. The desorbed compound such as n-hexane leaves the bed by line 58 and enters valve R-2 by port 4 whence it flows to both heat exchanger 53 and heating coil 60a, is condensed at 64 and is collected in tank 49. The n-hexane may be discharged through line 66 to storage. Valves 14, 62, 70 and 71 are provided to control the flow and pressure of the fluids in the various parts of the apparatus.

Abstract: 185,475. Ware, P. N. May 23, 1921. Combined transmitting and receiving arrangements; heterodyne receiving systems; thermionic amplifiers and detectors.-Telegraph systems are so arranged that either operator who is at the moment receiving may break in at will on the sending-operator. The receiving-station normally sends out continuous waves which enable the operator at the sending station to hear the signals he is sending out. A break-in is effected by the receiving-operator interrupting his oscillator and (thus rendering the signals audible to the sending-operator. The two stations are practically identical and either may effect the break-in. In one arrangement shown in Fig. 2, signals are transmitted and received on the same aerial 1 which is energized by an oscillating valve 7, the plate circuit of which in. cludes a key 18 and a low-frequency transformer 9 by which beat currents are transferred to amplifiers 10, 12 and telephone 15. The two stations emit normally waves of slightly different frequencies which produce audible beats at both stations. Signals are sent in either direction by keying the local oscillator circuit, the receiver being kept in an oscillating condition by maintaining its key 18 closed. The receiving- operator breaks in by opening his key, thus interrupting the local oscillator and destroying the beats at both stations. In another arrangement, one station of which is shown in Fig. 3, a separate transmitting-aerial S and receiving- aerial 22 are provided at each station, the receiving-aerial being connected to a heterodyne valve 24 the plate circuit of which includes a low-frequency transformer 27 by which beat currents are transferred through an amplifier 28 to the circuit of a telephone P. The sending- key K serves to control two circuits, closure of the key energizing a relay M which first closes contacts X, Y to energize the aerial S. and then closes contacts Y, Z to complete the telephone circuit. When the station shown is receiving, the key K is kept closed, thus enabling received signals to be heard as beats in the phone P. At the same time the emission of waves by the aerial S causes beats in the receiving-apparatus at the sending-station and these beats are heard whenever the phone circuit at the sending-station is closed by depression of the sending-key. The sending-operator thus hears the signals he is sending. If, however, the receiving-operator breaks in by opening his key K, no beats are produced at the sending-station and the sending- operator is informed of the break in. The key K has two arms one of which serves for signalling, and the other for making circuit more or less permanently whilst receiving.
