Title: Apparatus for converting latent heat of vaporisation to sensible heat
IPC: B01D5/00
Filed: 1958-04-16
Abstract: In apparatus for converting latent heat of vaporization to sensible heat, a gas or vapour containing water vapour or other condensable vapour is sprayed with water or other liquid at 7 as it enters a Venturi-tube to provide liquid <PICT:0923491/III/1> nuclei in the gas or vapour and water or other liquid condensed on the liquid nuclei is removed in the throat of the Venturi-tube by centrifugal means thereby to heat the gas or vapour issuing from the divergent portion of the Venturi-tube.  As shown in the drawing the centrifugal separation means comprises a throat 3 of curved spiral shape and separated liquid impinges against a baffle 9 and is withdrawn through a pipe 4 and may be recirculated by a pump 8 to the spray 7.  In a modification the gas or vapour entering the Venturi-throat is given a rotational movement by passage through guide vanes.  The apparatus may be used to effect a fractional condensation of condensable constituents from natural gas or the like and the liquid sprayed into the gas to form liquid nuclei may be one with a low vapour pressure.

Title: Work transfer and drive device in a transfer press
IPC: F02P17/12
Filed: 1976-03-26
Abstract: 1496428 Work transfer devices AIDA ENG Ltd 26 March 1976 [5 April 1975] 12188/76 Heading B3H A work transfer and drive device in a transfer press comprises a stationary shaft 6 supported in a press framework, an actuator gear 7 rotatably supported on the shaft 6, a sun gear 4 mounted coaxially with the gear 7 on the shaft 6, a planetary gear 10 fixed to an eccentric shaft 9 on the gear 7 in mesh with the sungear 4, a rotary member or disc 12 rotatably mounted on the shaft 6 and having a radial groove 12a for slidably receiving an eccentric pin 9b projecting from the shaft 9 and an eccentric pin 14, a first sliding member 15 guided by stationary guide bars 19 parallel to feed bars 17 and in which the pin 14 is received, and a second sliding member 18 connected to one of the feed bars 17 and to the first slidable member 15. The actuator gear 7 is driven by a prime mover (not shown) via gears 2, 3 and the gear 7 rotates the planetary gear 10 about the sun gear 4. The gear 7 also rotates the disc 12 by means of the eccentric shaft 9 and its pin 9b which as it slides in the groove 12a follows a locus B 0 - B 350 , Fig. 5. The rotational motion of the disc 12 is converted into linear motion of the sliding member 15 by the motion of a slide 16 in a slot 16a in the member 15. A pin 18a of a slide 18 in a slot 15b in the member 15 reciprocates the feed bars 17. There is a period of dwell at the end of each stroke of the bars 17 as the pin 9b moves through the portions (B 60 -B 120 ) and (B 250 -B 290 ) of its locus (Fig. 5, not shown). Clamps (17a), Fig. 1 (not shown), are mounted on the feed bars 17 and serve to hold workpieces (W) as they are transferred.

Title: Frequency selective network
IPC: H03H7/01
Filed: 1942-08-31
Abstract: 563,620. Telephone transmission systems. WHITE, S. Y. Aug. 3], 1942, No. 12241. Convention date, April 1, 1942. [Class 40 (iv)] [Also in Group XL] A frequency selective transmission network comprises in combination, a tube of limited power handling ability connected to a resonant circuit having a low ratio of inductance to resistance, and a detecting device deriving its control electrode potential directly from a terminal of said resonant circuit and insensitive to applied voltage below a predetermined threshold value, whereby the ratio between the selectivity and the number of cycles required to build up to full amplitude in the output of said network is markedly increased over the ratio inherent in any resonant circuit alone. As shown in Fig. 1, circuits TC3, TC4 tuned to a predetermined tonal frequency and having a low Q are optimum coupled to give high selectivity. The input to the circuits is fed through a limiter VT7 and the output is fed to a detector VT9 having a preset positive bias 20 applied to the cathode. The direct voltage appearing across load resistor R11, after filtering at R12, C8 is available for control purposes at terminals 21. If an input, applied from source 10, is of the predetermined frequency, the circuits TC3, TC4 rapidly build up to an amplitude sufficient to overcome the bias 20 and provide an output at 21. For any other frequency, however, the combined effect of the limiter VT7 and tuned circuits TC3, TC4 is such that the input to the detector VT9 is insufficient to overcome the bias 20 and no output appears at 21. Fig. 3 shows a mechanical embodiment suitable for use as the tuned circuits TC3, TC4. Brass strips 39 mounted on an insulating base 36, support insulating shelves 41, 43, 48, 49 between which are mounted coils 12, 14 having dust iron cores, and tuning condensers 13, 15 adjustable by screws 52. The whole is enclosed by a screening can and is provided with plug-in terminals 38. Specification 549,7.70, [Group XL], is referred to.

Abstract: 1495627 Fasteners C C COFFEY 25 March 1975 [27 May 1974] 12353/75 Heading F2H A toggle fastener 10, for use on the blind side of a wall in conjunction with a bolt extending through a hole through the wall, comprises a central member 11 with a bore 12 therethrough to receive the bolt, a pair of oppositely directed trunnions 13 projecting from the member 11 along an axis perpendicular to the axis of the bore 12, and a pair of oppositely directed flexible arms 14 projecting from the member 11 along an axis perpendicular to both the bore 12 axis and the trunnion axis, each arm 14 terminating in a wing 15 shaped so that when the arms are bent over to bring the wings 15 adjacent the central member 11, the wings may be engaged and held by the trunnions 13, Fig. 6. The trunnions 13 have knobs 20 at their ends. The wings 15 are connected to the arms 14 by necks 16 more flexible than the arms. The wings 15 have cutouts 21, and chamfered openings 18 to snap on to the trunnions 13. The fastener is moulded of a resilient thermoplastic material and may have grooves 17, Fig. 1, to permit the sides of the wings to be bent up at right angles to the plane of the central wing portion prior to engagement with the trunnions. Alternatively, Fig. 8, the wings are moulded in the bent-up form. In use, the fastener 10, formed as in Fig. 6, is engaged by the end of a bolt, and twisted relative thereto so that it can be inserted through a hole in a wall while engaged by the bolt. Once through the wall, the fastener resiliently returns to its Fig. 6 shape to engage the blind side of the wall and hold the bolt, which may then be tightened to secure an object to the wall.

Abstract: 494,823. Hooks ; lamp supports ; wall brackets. DAHM, A. E. April 25, 1938, No. 12363. Convention date, May 24, 1937. [Class 89 (ii)] [Also in Groups XI and XIV] The invention relates to a device for fixing a hook, lamp, bracket, shelf or like object to a wall, ceiling or other surface W by means of nails or pins F which extend through a positioning member A so that they diverge into the surface, the positioning member A being provided with a screw-threaded stem S or like fastening member adapted to receive an adjustable clamping plate B shaped and arranged to bear against the heads of the pins F. The invention consists in providing on the stem S an outer member C which may be tightened against the surface W so that its outward thrust causes the positioning member A to tend to move away from the surface. If the pins F work loose, tightening of the outer member C will cause them to be displaced laterally and their hold in the surface increased. The positioning member A may be of such thickness that the apertures therein guide the pins into position. The outer member C may be in the form of a dished cap clamped in position by a nut E which also secures a hook D in position. In a modification, the clamping nut is formed integrally with a supporting eye.
