[Also in Division F2] The invention relates to an air intake duct of a jet engine having a compressor and particularly to a seal device therefor. The engine 10 shown in Fig. 1 is mounted in an outer housing and comprises a compressor casing 12 at the forward end of which is mounted by flange connection 11, 26 a flexible tubular duct 20 formed for example of siliconerubber. The duct 20 is formed integrally with an annular inflatable portion 22 shown in the inflated position in Fig. 3 and in the deflated position in Fig. 4. The portion 22 is formed with a peripherally ribbed surface 25 which in the inflated position co-operates with surface 61 of the engine housing 60 so as to form a seal. In the deflated position the surface 25 is spaced from the surface 61 to facilitate engine removal. A leaf spring 24 is disposed within the seal member 22 to assist flattening when deflated. The member 22 is inflated when in operation by air tapped from the engine compressor 12 through line 30, see Fig. 5, a check valve 41 also a pressure relief valve 42 being provided in the line. The relief valve 42 co-operates with a lever 31 which is pivotally connected at (32) to the engine and at its other end to the engine housing. When the lever 31 is disconnected from the housing for engine removal, the lever moves to the chain line position Fig. 6 (not shown) in which it acts to open the relief valve 42 whereby the seal member 22 is deflated. The valve 42 may also be opened to drain moisture from the system. In a second embodiment, Fig. 7 (not shown), the seal member 22 is inflated by air from a ground installation compressor. The ends of the duct 20 are reinforced by metal rings 27, 28.

Abstract: 1,232,364. Ice cream production. BIG DRUM Inc. 20 Jan., 1970 [23 Sept., 1969], No. 2728/70. Heading A2B. A frozen edible article including a container filling therein, for example an ice cream filled cone, and a coating on the filling is produced by (a) disposing the containers upright on an endless conveyer with their mouths opening outwardly; (b) advancing the conveyer to a station wherein the containers are filled with the filling substance which can be frozen; (c) advancing the conveyer through a freezing tunnel with the filled containers being carried in an upright position on the upper run thereof and carried in an inverted position on the lower run thereof, the filling being frozen on emergence from the tunnel; (d) advancing the conveyers and inverted filled containers to a coating station wherein a coating is applied to the frozen filling, and (e) releasing the inverted filled and coated containers from the conveyer. After the application of the coating, preferably a syrup-type substance, edible particles such as nuts may be applied to the coated articles whilst the coating is soft. The process may be carried out in an apparatus of the type shown in Fig. 1 wherein ice-cream cones C are positioned in co-operation with gripping means in an endless conveyer 15, the conveyer passing firstly beneath a filling station 23 which station during filling moves in the same direction and at the same speed as the conveyer. After filling the cones pass through the freezing chamber 20 emerging in an inverted position and passing to a syrup coating applying unit 24, which unit during coating moves in the same direction and at the same speed as the conveyer. After coating, the filling may co-operate with a unit 24 for contacting the coating with edible particles. The finished frozen cones are then released from the conveyer and discharged on to a wrapping machine.

Abstract: 1,233,737. Programmed control. STARKSTROM-ANLAGENBAU KARL-MARXSTADT VEB. Aug.30, 1968, No.41492/68. Heading G3N. A switching arrangement for actuating the speed stages for stepped reduction of the speed of a moving part of a machine at programmed points when it moves to a required position, particularly in digital control systems, uses a computer by which the required values, actual values, and switching values are computed continuously. The system is oscillated between two gates by continuous signals of opposite sign at each step by which means spurious signals have no effect on the operation. When two successive signals of like sign are developed the speed is stepped to a lower value. The switching arrangement may be constructed as a counter, the number of switching stages corresponding to twice the number of speed stages required. The values V1-V4 Fig. 2 refer to switching signals for successive decrements of speed. When a position (V1) Fig. 1 (not shown) has been passed a circuit Z1 is required to reduce the speed. When in the programme a speed reduction is required, a signal is injected into the first stage 1 of a reversible counter 1-8. When the value V1 is reached, a computer (not shown) changes sign and supplies a forward pulse which switches the counter to stage 2 which energizes the circuit Z1 to reduce the speed. After a short determined interval, the computer again supplies a pulse which switches the counter to stage 3 which leaves the circuit Z1 unaffected, but stage 3 has an output V2 which causes the computer to change sign hence a reverse pulse is supplied to the counter to step it back to stage 2. The counter steps between stages 2 and 3 alternately until the position (V2) is reached by the moving part. The next time the counter is switched to stage 3 there is no reversal back to stage 2 and on the following computer pulse the counter will switch to stage 4, thus energize circuit Z2 and oscillate between stages 4 and 5 until position (V3) is reached. As the system is continually oscillating between two adjacent stages, a spurious interference signal of one polarity will have no effect and of the other polarity will cause the arrangement to switch to the other stage of a pair prematurely which will not cause the arrangement to switch to another speed range. Owing to the high speed of oscillations, relays employed in the circuit are prevented by their inertia from dropping out. In a preferred arrangement, the output unit is constructed as a counter having three bits with eight output states which is stated to eliminate redundant switching operations the store being supplied with a +1 signal for a negative computer output and conversely. The store stages should correspond to twice the number of speed stages required.

Abstract: 1,238,684. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 Nov., 1968 [30 Nov., 1967], No. 56276/68. Heading H4F. In a television synchronization separator of the type in which the high frequency pulse noise in the video signal is selected by a filter and applied via a threshold circuit and an envelope detector to an interference suppressing stage, the threshold level is raised during the sync pulses. As shown, Fig. 1, the video signal from demodulator 11 is applied to a filter 9, 10 which selects the high frequency pulse noise which is fed to a triode 13 to invert and rectify the noise which is then smoothed by capacitor 14. The resulting noise envelope signal is applied to the control grid 17 of a valve 1 together with a positive voltage V b  which determines the threshold above which the noise signal reduces the anode current of the valve. The composite video signal 4 is fed via video output stage 3 and network 5 to the second control grid 2 of the valve 1 which operates as an anode bend detector to separate out the sync pulses 6. The noise pulses in the composite signal are partially cancelled by the signal applied to the first control grid 17 but if a large noise pulse occurs during a sync pulse the valve may be cut off with the result that the separated sync pulse is subdivided into two or more pulses. To reduce this effect positive going line frequency pulses 19 derived from the line time base generator 20 are applied to the grid 17 of valve 1 to increase the threshold voltage for the pulse noise applied during the occurrence of the sync pulses. In an alternative embodiment, Fig. 2 (not shown), negative going line frequency pulses are applied across a resistor inserted between the lower end of inductor 10 and ground to increase the threshold during the sync pulses.
