Patent GB-1280804-A (GB)
Title: Apparatus for producing a gas/oil mist
Inventor: WOLF KRISTIAN
IPC: F16N7/34
Filed: 1970-10-28
Abstract: 1280804 Spray producers REINHARD KLINKHARDT KG 28 Oct 1970 51222/70 Heading B2F [Also in Division F2] An apparatus for producing a gas/oil mist for lubrication purposes has a container 2 for containing the oil and an atomiser head 1 having an inlet 6 for the gas and an outlet 7 for the mist, the gas supplied through a stepped passage 16 and thereby producing a suction in a passage 17 transverse to it, thus aspirating oil from the container 2 through an orifice 27 and a tube 26 having a non-return valve 25 which outlets in a drip chamber, the oil dripping from this tube passing through passages 14 and 17 to enter passage 16 wherein it is atomised, the amount of oil drawn from the container being controlled by a system of passages interconnecting the inlet 6 and the drip chamber in which there is a throttle valve 10. This system of passages consists of a bore through a restrictor member 15, an annular pressure chamber 12, a passage 9, the throttle valve 10, a passage 11 and a compensator orifice 8, a further passage 30 connecting passages 11 and 14, the bore of the restrictor member 15 being such that opening the throttle valve 10 fully can prevent any suction of oil up the drip tube. On leaving the stepped passage 6 the air/oil mixture impinges on a deflector plate at the bottom of a chamber 22, the mixture travelling out through a lateral orifice 23 to a passage 19 leading to the outlet bore 7. Thus deflection plate causes the larger oil droplets to return to the chamber 2. The mist may be used to lubricate high-speed spindles in grinding machines.

As shown, the key-hole aperture 48, which is arranged uppermost when the adaptor is used, is disposed in a tongue 64 which is separated from the remainder of a body portion of the adaptor by a U-shaped slot 62; the provision of the tongue allows upward movement of the body portion after the first stud is seated in the aperture 48 to be lifted to engage the second stud. The upper end portion 76 of the adaptor has a pair of fins 88 which separate the strip from the panel; the lower end portion also has a pair of fins 84 and also two fingers 82. The fins are disposed underneath the flange 78 and the fingers are received in the flange. The fingers hold flange 78 in place, the other flange of the trim strip being snapped beneath a downwardly facing shoulder 86 of the body portion. The fingers compensate for tolerance variations in the strip width. Opposed edges 90, 92 of the adaptor are truncated to allow the adaptor to grip different widths of trim strip.

Abstract: 1,147,750. Endless conveyers. FMC CORP. 18 Dec., 1967 [5 Jan., 1967], No. 57438/67. Heading B8A. Spaced lines of containers C are formed from a steady input on an endless conveyer 12, by the action of a slower running endless conveyer 16, the spaced lines of containers C being then moved successively into the path of a feed means 40 (Fig. 8) which causes them to be displaced laterally. The conveyer 16 comprises a laterally spaced pair of chains which carry two longitudinally spaced series 30, 31, of rubber pads (33), (Fig. 3, not shown) each of which stands proud above the supporting surface of the conveyer 12. Thus as the leading pad of one of the two series 30, 31, reaches the beginning of its operative horizontal run (Fig. 4), the first container to be engaged is slowed down, and succeeding containers progressively back-up behind it. A gap is thus formed between these containers and those preceding the first container to be slowed down, since the latter are being conveyed by the faster conveyer 12. When the trailing end of the pad series 30 (or 31) reaches the end of the horizontal run (Fig. 4) the leading end of the other pad series 31 (or 30) is just reaching the beginning of the run (Fig. 4). The pad series 31 thus permits the remainder of the backed up containers to be conveyed again by the conveyer 12 and thus to become spaced from those backing up behind the leading container engaged by the pad series 31. The spaced series now on the conveyer 12 downstream from the conveyer 16 is deflected by a rotary member 43 into a pocket 40A of a transfer reel 40 (Figs. 7 and 8). The latter feeds an endless conveyer 41. The conveyers 12 and 16 are driven by gearing from a drive shaft 26 from which further gearing provides the drive for the member 43, the reel 40, and the conveyer 41.
