Title: Automatic control system
IPC: G05D1/08
Filed: 1970-05-18
Abstract: 1309436 Automatic control of aircraft SOC  FRANCAISE D'EQUIPEMENTS POUR LA NAVIGATION AERIENNE 18 May 1970 [19 May 1969] 23899/70 Heading G3R The pitch attitude of an aircraft is automatically controlled by an error feedback system including a gain-compensating arrangement. In Fig. 3, a signal X, which is the difference between a signal # dependent on the pitch attitude of an aircraft 21 and a signal # c  representative of a desired pitch attitude, has first and second differential components added at 15 and is applied to a limiter 17. Two different proportions of the output of limiter 17, determined by gain controls 13a, 13b are added together at 19 and applied to an integrator 1 the output of which controls an electro-hydraulic actuator 7 adjusting the elevators to correct the pitch angle of aircraft 21. A signal  dependent on the output of integrator 1 is fed back through a high-pass filter 10 and a full-wave rectifier 11 so that, regardless of sign, it controls a device 12 to vary the gain of one component of the input to integrator 1. This variation of gain compensates for variation of effectiveness of the elevators at different positions.

Inventor: ROSE RICHARD ARTHUR
IPC: B29C48/91
Filed: 1964-06-09
Abstract: 1,056,237. Casting cellulosic films. BRITISH CELLOPHANE Ltd. May 28, 1965 [June 9, 1964], No. 23941/64. Heading B5B. Cellulosic film is made by extruding a settable cellulosic material through a slotshaped orifice on to the surface of a fully-set cellulosic carrier film and treating with at least one setting liquid to form a coherent cellulosic film while the setting cellulosic material is continuously supported on the carrier film in a tensionless state until setting is complete, and thereafter stripping the set cellulosic film from the carrier film. The carrier film may have been freshly cast with or without further treatment but not dried, or it may have been dried and then rewetted. The two films may thereafter undergo liquid treatment, e.g. washing and purification, either together or after separation, or with separation and subsequent unification. The hydroxyethyl composition of the two films may be the same or different, e.g. viscose, which may have degree of polymerization 350-600, or hydroxyethyl, e.g. cellulose. The films may be prepared by use of a standard double-web casting machine with a separate setting bath.

Title: Motor vehicles having folding canopies
IPC: B60J7/20
Filed: 1974-05-30
Abstract: 1463578 Folding canopies for motor vehicles DAIMLER-BENZ AG 30 May 1974 [30 May 1973] 24016/74 Heading B7B [Also in Division E2] A motor vehicle has a folding canopy of which the rearward extremity is formed by a fabric support yoke engageable with a lock 4 which, together with two fasteners for the lid of a box for receiving the canopy when folded, is controlled by a remote control mechanism 1 located in the passenger compartment. When a hand lever 5 of mechanism 1 is shifted to position I (Fig. 3), its movement is transmitted via a crank 7, link 11, rod 12, bell-crank 3 and rod 14 to a claw lever 16 in the lock to cause the claw lever to pull a locking lever 1 down against the bias of spring 18 from position I to position III, the locking lever at this stage being engaged with the yoke and serving to tension the canopy. With lever 5 in position 1, the point of connection between crank 7 and link 11 has moved over-centre to prevent inadvertent unlocking. When the lever 5 is subsequently moved towards position II, the locking lever 17 is moved upwards by the claw lever 16, spring 18 and the tension in the canopy and is constrained by pivoted cam 23 to pivot to position II to release the yoke, the cam being co-operable with a surface 21 of the lever and being engageable with a stop 22 which limits rotation of the cam in one direction, there being no restraint on rotation of the cam in the other direction so that there is no tendency for the lever 17 to pivot when moving from position I to position II. The lever 17 can be pivoted to position II independently of lever 5 by means of lever 27 which is coupled to the lever 17 via lever 26 and cable 25, this facility permitting release of canopies with little inherent tension. The lever 5 also controls operation of the fasteners serving the box lid, one fastener (not shown) being actuated via cable 13 extending thereto from bell-crank 3 while the other 2 is actuated via crank 8 and link 9, both fasteners being unlocked as the lever 5 reaches position II.

Title: A control system for turning indicators and headlamps on automobiles
IPC: B60Q1/36
Filed: 1948-09-15
Abstract: 647,381. Switching systems. CLIVE, J. Sept. 15, 1948, No. 24285. Addition to 610,909. [Class 38 (iv)] [Also in Group XXXVIII] In a vehicle direction indicating system as described in the parent Specification in which a headlamp is swivelled by a solenoid energized when the corresponding indicator arm is actuated, the solenoid circuit is completed by contacts actuated by the arm itself. When an indicator switch 2, 3 is moved to the left or right a solenoid 6 or 7 is energized to raise a signalling arm 8 or 9 respectively in the usual way. When a headlamp switch 27 is closed the lamps 24, 25 are illuminated, and if then a dipper switch 31 is moved to contact 33 the right-hand lamp 45 is extinguished and a solenoid 22 is energized to swivel the other lamp 24 to the left and downwards. When the indicator arm 8 is raised it closes contacts 10, 12 to light its own lamp 14 and also closes further contacts 16, 18. If a control switch 28 is also closed and the headlights are switched on at 27, battery from lead 26 is connected over contacts 37, 38 to the solenoid 22 which operates to swivel the corresponding headlamp 24 to the left. Similarly the raising of the other indicator arm 9 swivels the right-hand headlamp 25 to the right. When one headlamp has been swivelled it breaks the solenoid circuit of the other lamp at contacts 37, 38 or 34, 35 by means of a camprojection 39 or 36. If the normal dipper switch 31 is thrown with both switches 27 and 28 closed, it extinguishes the right-hand lamp 25 and energizes solenoid 22 to turn the other lamp 24 to the left and downwards in the normal way, and this in turn breaks the circuit to solenoid 23 at contacts 34, 35.

Filed: 1931-09-02
Abstract: 385,355. Universal joints. DEHN, F. B., 103, Kingsway, London.-(Thompson Products, Inc. ; 2196, Clarkwood Road, Cleveland, Ohio, U.S.A.) Sept. 2, 1931, No. 24668. [Class 65 (ii).] Pivoting-adjustments.-In a universal joint, particularly for the steering-gear of a motor vehicle, comprising a housing on the end of the track-rod, a cylindrical stud in the housing, a split bearing shell surrounding the stud, and a rubber bushing pressing the shell against the stud to take up wear, relative axial displacement between the bearing shell and the rubber bushing is prevented, either by end flanges of the shell engaging the rubber bushing or by the bushing embracing the ends of the shell. In the form shown in Fig. 1, the housing 11 is secured to the screwed end of the rod 15 by split tubular part 14 with clamping bolts ; the split extends into the socket, which is therefore tightened round the bearing by the clamping bolts. The stud 13 passes through an aperture 12 in one end of the cylindrical housing 11 and has a flange 18 at the free end of the cylindrical bearing surface 17. Round the bearing surface is an oilless bushing 21, which may comprise a split metal shell with a compressed graphite lining, as shown, and between this bearing shell and the wall of the housing is a compressed rubber bushing 25 enclosed in a sleeve 24, which is gripped in the housing when the clamping bolts for the split part 14 are tightened. The rubber ring tends to close the bushing around the stud to take up wear, and also allows some universal movement of the joint. It is held in place by a felt washer and a metal washer 19 engaging the flange 18 on the stud, and it overlaps the ends of the bearing shell 21 to prevent axial displacement of the bearing shell relatively to the rubber bushing. In a modification, Fig. 3, the rubber bushing is formed in two semicircular halves 28, and the bearing shell 21 is replaced by a metal member, also formed in two halves 26, provided with flanges partly embracing the ends and sides of the rubber members ; the sleeve 24 surrounding the rubber bushing is omitted in this form.
