Abstract: 1,273,645. Electromagnetic stepping switch. SIEMENS A.G. 24 Sept., 1970 [26 Sept., 1969], No. 45432/70. Heading H1N. An electromagnetic rotary stepping device for a switch has a transmission device between its rotary armature and an output member which is rotated in steps which are larger than the armature movements and the armature and all movable parts of the transmission device are dynamically balanced about their respective axes of rotation. The armature 8 co-operates with a coil and yoke assembly (Fig. 1, not shown) and is biased by a spring 23. The transmission device is a two armed lever 28 pivoted on a pin 29 and having a pin 30 on its short arm engaged in a slot 18 in the armature 8. A pin 31 on the longer arm of the lever 28 engages in a slot 32 in a segment plate 33 which is biased by a spring 35 into engagement with ratchet teeth 39 of an output member 36 which also has recesses 41 which are engaged by a tooth 40 at the end of each forward rotation of the member 36 to prevent over-running. A detent spring 42 co-operates with notches 43 to prevent backward rotation. The member 36 has pins 48 engaged in holes in a wiper spring 47 arranged to connect a conductor area 50 to contact areas 52 in turn as the member 36 is stepped round. The areas 50, 52 are formed on a printed circuit plate 45 having conductor areas 53 between the contacts 52 to ensure that the spring 47 will always be in engagement with a metal surface. A sealed housing for the complete assembly may be provided (Fig. 4, not shown).

Title: Method of and apparatus for treating particulate material with a gas
IPC: A23P30/38
Filed: 1973-09-28
Abstract: 1407753 Treating foodstuffs G E BROWN and D F FARKAS 28 Sept 1973 [8 Nov 1972] 45612/73 Headings A2B and A2D [Also in Division F4] The invention relates to an apparatus for and a process of treating particulate material with a gaseous medium, e.g. sulphur dioxide. Such treatment may produce dehydration of food, or puffing, bleaching or cooking of food or be used for preserving foods. The apparatus comprises a housing 20 having a gas inlet at one end and a gas outlet at the other, a perforated cylinder 23 mounted for rotation within the housing 20 and positioned so that gas passing from the inlet to the outlet passes through the cylinder 23 in a direction transverse to the rotational axis thereof and means for rotating the cylinder at a speed sufficiently high for a specified material to hold the major portion thereof against the wall of the cylinder by centrifugal force. Means, e.g. a blower (Fig. 1, not shown), are provided for impelling gas through the housing at a velocity high enough that from 25 to 50% of the material is formed into a fluidised mass in and adjacent to the portion of the cylinder adjacent the gas inlet during use of the apparatus. Material may be fed to the cylinder by a vibratory feeder and the cylinder may be driven by a variable speed motor 24. A screen 27 position upstream of the cylinder 23 assists in providing uniform flow of gas and louvres 26 provide an adjustment of the direction of gas flow through the cylinder so that the air may produce feeding of the material from one end of the cylinder to the other. Alternatively the cylinder may be angled to the horizontal. In a further embodiment (Figs. 1, 2, not shown) a removable door is provided at one end of the cylinder. The process is particularly applicable to the treatment of particulate fruit, vegetables and meat.

[Class 75 (iii)] A gas-igniting device comprises a spring- controlled friction-wheel o mounted on an axis at right-angles to that of a manually-operated gas cock e, or rotary member 21, and a pair of levers j, 2, or 24, 30, connected respectively to the gas cock e, or member 21, and the wheel o, the arrangement being such that, on turning the cock e, or member 21, in one direction, the wheel e is turned against the action of its spring 3, or 31, until the levers are disengaged and the wheel is rapidly returned to strike sparks from the flint t. The member 21 may form, or be secured or connected to the gas cock. As shown in Figs. 2 and 3, a gas torch d for use on a gas cooker is supplied through a flexible tube from the cock e and is adapted to be inserted in a hole h in the cock and be supported by a collar g engaging an abutment i. On turning the torch through 90‹ to open the cock, the wheel o is operated to ignite the torch, which can then be detached for igniting the burners. The adjacent ends of the levers j, 2 are turned over at right-angles. On closing the cock, the lever j slides past an inclined surface 6 on the lever 2 against the action of a spring k until it leaves the lever 2 and is returned by the spring k to the normal position. The flint tube s is slotted to receive the arm u of a spring w, coiled round a boss x and engaging an abutment y. In the gas-fire burner shown in Fig. 9, gas is supplied to one or more pilot jets 12 and the igniter is operated to ignite the jets by turning the gas cock e against the action of a spring 13 beyond the fully open position. The spring 13 is stressed by engaging an abutment 15 and returns the cock to the fully open position. In the igniter shown in Fig. 9, the member 21 is mounted in a yoke 20 on a plate 19, provided with a cover (not shown), and may be provided with a return spring 23. The spring- - pressed lever 24 is slidable radially in the member 21 so that it is pressed back by engagement with an inclined face 33 of the lever 30 during the return movement of the member 21 until it leaves the lever 30 and is returned by its spring 25 into the normal position for re-engaging the edge 32 of the lever 30.
