Abstract: 1523618 Course position indicating apparatus SOC FRANCAISE D'EQUIPEMENTS POUR LA NAVIGATION AERIENNE SFENA 18 Nov 1975 [18 Nov 1974] 47460/75 Heading G1F Apparatus installed on an aircraft &c. for indicating position on a chart comprises a point 16 carried on a wire 15 which is displaceable by motors 17, 26 driven in dependence of signals received from two known beacons. In use a chart 9 is secured in a slot 1 in the apparatus housing 4 and pointers 11 are aligned with a meridian line on the chart: their position, giving the orientation of the chart in the slot, the magnetic declination and map scale are entered in the memory of the craft computer, the radio receiver having been set to the beacon frequency; the pointer is positioned successively over the positions on the chart of the beacons and the positions entered in the memory. Information received from the beacons is processed by the computer to drive the motors 17 and 26 and locate the point 16 on the aircraft's position on the map. The pointer then follows the aircraft's course. The chart is clamped in the slot by means 6, 7 during use and when it is released the computer is reset automatically to zero.  The point 16 may be located over an objective to be reached in the same way as over the beacons and the computer caused to supply the automatic pilot with information to reach the objective.

Abstract: 1,170,988. Endless conveyers. VEREINIGTE SCHMIRGELUND MASCHINEN-FABRIKEN A.G. 26 Oct., 1967 [15 March, 1967], No. 48634/67. Heading B8A. Material 4 conveyed on carrier rods 2 supported by endless chains 3 (at their respective ends, laterally outward of the material) tends to develop marks 4a due to contact with the rods 2. In order to prevent the marks 4a becoming too permanent, the material is moved relatively to the rods. First, the rods are straightened up laterally by a member 1 and are then picked up by a pair of auxiliary endless chains 12. These increase the spacing between the rods and feed them to a second pair of friction-faced endless chains 5 which are overlied by a pair of spring urged members 10. These cause the rods to rotate and so move the material relatively to each rotating rod. The material 4 may be abrasive paper or wall paper.

[Also in Division H3] Failure of a signal lamp circuit connected in series with the primary of a ferrite core transformer changes the current in the secondary to actuate a switching device. Red traffic lights 1 . . . 6 and pedestrian lights a, b for a NS direction are coupled via ferrite core transformers m 1 , m 2  and rectifiers D 1 , D 2  to OR gates D 5 , D 6 . Under normal conditions the outputs from the two transformers are rectified to produce a D.C. signal to reverse bias diodes D 5 , D 6 , so that transistor T 1  is conductive. Failure of any one of the lamps results in a change in the secondary current of m 1  or m 2  sufficient to forward bias D 5  or D 6  and cut-off transistor T 1 . A similar arrangement for the EW direction is coupled to transistor T 2 , so that an output signal is only produced when both transistors are cut-off, i.e. when a light in both directions fails at the same time. If green lights show in both NS and EW directions at the same time, this will also mean that no red lamps are lit, and the output signal (which can be used, for example, to flash an amber) will again be produced.

Abstract: 1361668 Oven-door locks ETABS EUGENE SCHOLTES 28 Oct 1971 [30 Oct 1970] 50088/ 71 Heading E2A . An electric kitchen oven is designed for permitting the cleaning of its inner walls by the burning-off of the fatty or other deposits form thereon and comprises an electro-mechanical device for locking the manual bolt of its door during the cleaning operation, the oven being characterised in that the electric circuit for energising its heating resistors 3a, 3b comprises a single thermostat 2 adapted to be adjusted for various control conditions including the aforesaid cleaning operation as a function of the angular position of the knob provided for controlling the position of a control switch such switch being so arranged that in the angular position of said knob which precedes the cleaning control position the electromechanical device can be actuated to permit the operation of the door bolt to the door fastening position preliminary to the cleaning operation whereas in the angular position corresponding to the cleaning operation the rotary switch is adapted to energise the heating resistors through contacts 11 which are closed by the movement of the door bolt to the door fastening position and contacts 4 adapted to be opened by a timing or programming device after a time period sufficient for completing the cleaning operation, the circuit for actuating the electromechanical device being completed via the thermostat contacts so that the door can only be opened when the contacts of the thermostat are closed so that opening of the door doing the cleaning operation is prevented. In the construction shown the electromechanical device is of the kind described in Specification 1249454 and which includes an electromagnet 8 which when energised moves a slidable detent to a position in which the door bolt can be moved between fastening and releasing positions and vice versa and which when the electromagnet is de-energised prevents movement of the door bolt. The electromagnet is controlled by a push button switch 9 which when depressed completes its circuit via the thermostat contacts; when the electromagnet is energised a signalling lamp is also energised thus at the end of the cleaning operation if the lamp lights when the push button is depressed the thermostat has closed because the oven temperature has fallen low enough and indicates that the door can be opened. The angular position of the knob which precedes the cleaning operation is also used to. permit the operation of the oven as a grill a resistor 5 being energised in this position instead of the resistor 3a and 3b. When either the resistors 3a and 3b or the resistor 5 is in operation a resistor 6 is also in operation, this is the heating resistor of a catalytic device which is intended to remove fumes. .

Abstract: 1,176,287. Extrusion die heads. CAMPBELL SOUP CO. 24 Oct., 1968 [16 Feb., 1968], No. 50534/68. Heading B5A. In a die head 16, particularly intended for the extrusion of viscous adherent material such as uncooked ground meat, a fixed multi-orificed die plate 110, Fig. 6 which may be of plastics, has situated immediately downstream thereof a rotatable forming plate 126 and a rotatable shear plate 140, both having an orifice configuration identical to that of the die plate. In operation, material is intermittently forced into the orifices 120 of die plate 110. Initially, orifices 132 in forming plate 126 are in non- alignment with orifices 120, but as the forcing pressure increases, forming plate 126 is rotated to cause alignment of orifices 120, 132 to allow extrusion therethrough and through aligned orifices 142 in shear plate 140. As the extrusion pressure decreases, forming plate 126 rotates back to its initial position and has hanging therefrom substantially spherical shaped pieces of material; see Figs. 7-10 (not reproduced), for above-described cycle. To remove these pieces from the forming plate, shear plate 140 is rapidly rotated out of and back into alignment with orifices 120, see Fig. 11 (not shown), the shear plate orifices 142 being bevelled to provide cutting edges. The die head 16 is part of an extrusion apparatus in which motor 22, Fig. 1, drives a main shaft 44 via a clutch 32, and shaft 44 causes intermittent uni-directional rotation of screw impeller 12 via an eccentric crank arrangement 74 and an over-running clutch 76, see also Fig. 2 (not reproduced). Forming plate 126 is rotatably driven from shaft 44 via bevel gears 200, an eccentric 202 and a crank arm 136 coupled to an ear (130), Fig. 4 (not shown), of the plate. Shear plate 140 is rotated when a cam 210, Fig. 1, on shaft 44 actuates a microswitch 215 once in each revolution of the shaft. The micro-switch actuates a solenoid 216 to trigger a single-cycle air cylinder 218 connected to ear 144 of the plate, see also Fig. 4 (not reproduced). The extruded portions, e.g. meatballs, fall into a shoot 18, Fig. 1, on reciprocation of the shear plate, and thence to one of a series of fryer pans mounted on an indexable turntable (not shown) driven by a drive-shaft 20.
