Abstract: 1517335 Machinery safety devices; linkwork; cams INDUSTRIAS AUXILIARES ELECTRODOMESTICAS SA 9 July 1975 28906/75 Headings F2J and F2K In a spin dryer having a pivoted lid 14 covering a rotary drum 9 which is driven by an electric motor 7 suspended by resilient links 51 on a panel wall 4 separating the spin drying chamber 5 from the motor housing 6 in an overall casing 1, the motor 7 is automatically deenergized, and braked to a standstill, on opening the lid 14 by a projection 33 on the lid releasing a plunger 31 of the motor switch 32 arranged in a sealed compartment 27 adjacent the lid 14, the switch 32 being connected to the motor 7 by a cable, i.e. conductor 35a which extends through an external channel 37 on the outer wall of the casing 1 over the extent of and remote from the dryer drum chamber 5. As shown in Figs. 1 and 4, the lid 14 is retained in a closed position by a simple spring-loaded pivoted lever latch 21. In Figs. 11 to 22 (not shown), a pivoted lid (105), having a similar spring-loaded pivoted lever latch (110) and a motor operating switch projection (117) as before, has an additional, i.e. inner lid (124) pivoted thereon, which inner lid carries a projecting portion (128) which, when the lids are closed and the drum is rotating, is engaged by an air-vane latch (129, 130) responsive to air movement of the rotating drum. The arrangement is such that when the outer lid is released and opened and the motor de-energized and braked, the inner lid is retained in its closed position until the drum stops and the air-vane latch pivots clear of the portion (128) for full release and hence opening of the inner lid. The inner lid additionally has shaped feet (134) which when the inner lid (124) is closed, engage apertures (135, 136) (Fig. 20) in the top (101) of the casing and are then laterally moved and locked beneath the apertures (135) (Fig. 21) as the outer lid (106) is closed due to the offset of the inner lid pivot (122) relative the outer lid pivot (104). Figs. 23 to 35 and 36 to 43 (all not shown) illustrate further embodiments in which a single lid carries the motor operating switch (226) which is controlled by a manual knob (211) incorporating a displaceable cam device (216) which when the lid is open is axially displaced along a pin (210) of the knob away from the switch (226) but when the lid is closed is axially moved into engaging alignment with the switch whereby the knob may be turned to lock the lid shut and start the motors or unlock the lid and de-energize the motors &c., the arrangement also including an air-vane latch (231) which, as before, when the drum is rotating, pivots into the path of a locking extension of the knob preventing full release of the lid until the motor is switched off and the rotating drum braked to a standstill.

Title: Process of making pectous material and product
IPC: C08B37/06
Filed: 1934-10-12
Abstract: Material containing pectose, e.g. fruit pulp, is washed to remove water soluble ingredients, the pulp is then mixed with a filter aid, such as kieselguhr, and is pressed and dried.  Jellies may be obtained by hydrolyzing the pectose to pectin.  The washed material may be finely ground before addition of the filter aid, and sulphurous acid may be added at this stage.  The pressed material is disintegrated and dried, for example in a rotary drier, leaving about 4 per cent of moisture therein, and is then standardized to a definite gel strength by addition of other pectous material, or of a sugar such as cerelose, or by addition or removal of inert material such as kieselguhr.  The gel strength is tested by boiling the material with hydrochloric acid to hydrolyse the pectin, filtering off the pectin liquor, partly neutralizing the extract by means of sodium acetate, adding to various amounts of sugar, boiling down the mixtures, and leaving in vessels containing a little citric acid for 12 hours.  The minimum amount of extract required to give a satisfactory gel with a definite quantity of sugar is a measure of the gel strength. Specification 184,081, [Class 121], is referred to.ALSO:A fruit jelly is prepared by adding hydrochloric acid to a pectous material from which water soluble materials have been removed, boiling to hydrolyse the pectose to pectin, filtering off the pectin liquor, reducing its acidity and boiling down with sugar. Citric acid is added before the jelly is stood aside for setting. Specification 184,081, [Class 49], is referred to.
