Title: Improvements in navigational steering systems
IPC: G05D1/02
Filed: 1933-04-05
Abstract: 417,658. Steering automatically. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. April 5, 1933. No. 10198. Convention date, April 6, 1932. [Class 4.] The rudder of an aircraft or ship is operated continuously in accordance with the rate of departure of the craft from its course and a correction factor is periodically introduced to correct the operation of the rudder in accordance with the angle of departure. The usual rudder bar 23 is connected by adjustable links 21, 22 to a pivoted bar 19 connected to two bellows 14, 15 which are normally kept equally exhausted by connections to two Venturi-tubes 26, 27, through adjustable valves 28, 29. The bellows are connected by pipes 39, 41 to orifices 42, 43 in a block 64 which are normally covered, but a pointer 36 on a gyroscopic turn indicator 32 is adapted to uncover either orifice as the machine yaws and unbalance the pressures in the bellows. The gyroscope is driven by a suction device actuated by a Venturi-tube 33. The bellows are also connected through pipes 38, 40, valves 60, 61 and pipes 58, 59 to orifices 56, 57 in the dial of a galvanometer 44 having a pointer 54 moved in accordance with the indications of a compass 45 similar to that described in Specification 388,085. The orifices are normally closed by a flap 55 on the pointer 54, and to enable the pointer to move, the pipes 58, 59 are vented at intervals by a timing device 62 acting on the valves 60, 61. The orifices in the block 64 are normally covered with strips of rubbered fabric 66, 67, Fig. 6, anchored at their outer ends to metal strips and at their inner ends to levers 72, 73 freely pivoted on the spindle of the pointer 36. This pointer, which is normally kept central by a spring 76, has a pin 75 projecting between the levers 72, 73 so that displacement of the pointer causes one or other of the strips 66, 67 to be rolled up and uncover the corresponding orifice. The pointer 36 is damped by a dash-pot 81. The timing device 62 comprises a bellows subjected to the suction of the Venturi-tube 33 and having cam strips on its movable board to throw over a valve to vent it to atmosphere when completely collapsed, the valve being again thrown over when the bellows is completely extended. An arm on the movable board acts on two spindles of the valves 60, 61 to vent the valve-chambers to atmosphere and close the pipes 38, 40 every time the bellows is collapsed. The course is set by a lever 50, Fig. 1, in conjunction with a lubber point 52. Pistons and cylinders may replace the bellows 14, 15. Specification 388,085, [Group XX], also is referred to.

Title: Process for the mnufacture of Vinyl Esters of Carboxylic Acids
IPC: C07C67/055
Filed: 1968-03-04
Abstract: 1,188,737. Vinyl esters. FARBWERKE HOECHST A.G. 4 March, 1968 [3 March, 1967; 10 Aug., 1967], No. 10364/68. Heading C2C. Vinyl esters of carboxylic acids are prepared by a process which comprises passing ethylene, oxygen or gases containing oxygen, and carboxylic acids in the gaseous phase at an elevated temperature over a catalyst comprising a carrier, e.g. silicic acid, a salt of a noble metal of Group VIII of the Periodic Table, and also 0À01 to 200 grams, per litre of catalyst, of cadmium in the form of the cadmium salt of a carboxylic acid. The catalyst may contain a cadmium compound which forms the cadmium salt of a carboxylic acid under the reaction conditions. Advantageously the reaction may be carried out in the presence of an alkali metal salt of the carboxylic acid to be reacted, e.g. the potassium salt thereof, and/or in the presence of a redox system, e.g. an iron salt. Preferably, that part of the catalyst which first comes into contact with the reaction gases is exchanged either by a periodical reversal of the direction of flow of the gases over the catalyst, or by continuously or periodically removing part of the catalyst from the inlet of the reactor, and adding it at the outlet of the reactor, or alternatively by continuously or periodically thoroughly mixing the catalyst.

Title: Improvements in or relating to the operation and control of change speed gearing, particularly applicable to motor cars
IPC: F16H59/68
Filed: 1921-04-09
Abstract: 183,198. Ter Cock, C. April 9, 1921. Controlling variable-speed gearing.-An electric signalling-device is caused to give an audible or visual signal while the gears are being changed, which stops when the gears are in mesh. As applied to a motor-car, when the ignition switch is closed prior to starting, a signal is given if the gears are not in neutral, preventing the clutch being put in while gears are in mesh. The invention is specially applicable to solenoid-operated gears such as that described in Specification 105,192. The control handle 7, described in Specification 173,802, is turned to select the new gear, and when in neutral position is slid longitudinally to bring the reverse drive into action. The selective controller 8 is geared to the handle 7 and turned thereby. A single solenoid 21 functions to actuate the selector mechanism to change the gear. A second solenoid 18 is for unlocking the selector. When gears are brought into mesh, a main contact 23 is disconnected, so that a buzzer or the like 28 stops. The ignition switch 2 is coupled to a twoway tumbler 3. When the switch 2 is closed as in running the car, the tumbler 4 connects contacts 5, 6, and current passes from the battery 9 through a switch 10 accessible only to an authorized person, past the handle 7, through the controller 8, and through the solenoids 18, 21 one at a time. The solenoid 21 is in parallel with the buzzer 28 and tumbler 4, and the current from both passes the contact 23, which, when broken at the end of the gear-shifting operation, stops the signal. When the switch 2 is open, as when the car is stopped, the tumbler 4 comes to the position shown, and the buzzer sounds if the ccntrol handle 7 has not been brought to neutral. Bringing the handle to neutral breaks this circuit at the contacts 15, 19 of the controller. For reversing, the controller 8 being in neutral is cut out, and current passes by contact 36 of the handle 7, which has been slid longitudinally, and through the solenoid 21 and buzzer 28 in parallel until the contact 23 is disconnected on completion of the change.

Title: Method for producing a master alloy for use in aluminium casting processes
IPC: C22C21/00
Filed: 1971-04-21
Abstract: 1333957 Producing aluminium-based alloys GRANGES ALUMINIUM AB 21 April 1971 [28 April 1970] 10521/71 Heading C7D An aluminium-based master alloy is prepared by subjecting an aluminium melt containing 0À02 to 6 per cent by weight titanium and 0À01 to 2 per cent by weight boron in the form of titanium diboride to agitation for a period of 15 minutes to 9 hours at a temperature between the melting- point of the mixture and 900‹C. Titanium and a boron salt or fine-grain titanium diboride TiB 2 , are added to the aluminium melt and dissolved at a temperature between 1200‹ and 1500‹C.; the melt is then rapidly cooled to below 900‹C. Alternatively, the mixture can be cast into small watercooled moulds, and then re-melted. Holding the temperature between the melting-point and 900‹C. enables Al 3 Ti to crystallize out around the TiB 2  grains and form cystallization nuclei when the master alloy is added to an aluminium casting melt conferring a finer grain size on the cast aluminium product. A preferred temperature range for the holding operation is 680-720‹C. over a period of 45 minutes to 2¢ hours. The master alloy can be added to the aluminium casting melt while still in molten form or after solidification. It is stated that the method could be extended to any aluminium melt which is to be treated with titanium and boron.

A table for facilitating the application of metal bands to packing cases comprises 'a rectangular frame 11 supported by legs 10 and provided with rotatable balls 12 on which the case rests during the banding operation and parallel channels 13 having ramps 14 and slots 15 at either end. Reel holders 16 are hinged at 17 to the legs 10 so that they may be swung outwardly to enable reels of banding material to be inserted and then swung inwardly and locked in position by latches 25 so that the reels are aligned. with the channels. The banding material is fed from each reel through one of the slots 15, down the associated ramp 14, along the associated channel 13, up the ramp at its other end and around the case so that it may be tensioned and secured. A head 26, which is supported by a rotatable spindle 27 and normally located below the surface of the table is then raised by a pedal-operated lever 29 to lift the case clear of the balls 12 so that it may be rotated through 90 degrees. The head is then lowered and further bands applied to the case in a similar manner. A projection on the spindle 27 may co-operate with V-shaped notches on a fixed surrounding ring so that the head is located in the required angular position as it is lowered. The head may be formed with slots 32 which co-operate with further channels 33, 34 to enable central bands to be applied to the case.

Title: Improvements in or relating to the manufacture of starch and the improved starch product resulting therefrom
IPC: C08B31/18
Filed: 1942-07-29
Abstract: Thin boiling starch having a low solubles content is prepared by reacting a suspension of native starch in an aqueous solution of mineral acid containing a hexavalent chromium compound, such as chromium trioxide or a chromate, dichromate or chlorochromate, at a temperature below the swelling temperature of the starch granules. The reaction may be continued until substantially all the chromium compound has been reduced.  For a given length of time of treatment, the addition of increasing amounts of chromium compound causes an increase in alkaline fluidity and, on the average, a decrease in solubles formed.  With increasing time of treatment, the alkali fluidity rises rapidly up to a certain point and then changes relatively slowly.  One half the weight of hydrochloric acid gives the same effect on alkali fluidity as sulphuric acid, but about 20 per cent more solubles are formed. Preferably, a suspension of 380 parts by weight of starch in 450-1000 parts of water, i.e. 22.5 DEG -13.5 DEG  B<\>ae, is reacted with .1-9 parts of mineral acid and .15-10 parts of chromium trioxide between 35 DEG  C. and 65 DEG  C. from 10 mins. to 6 hours.  The acid present may then be neutralized or partly neutralized and the starch recovered by filtering, washing and drying.  The product will give very viscous gels when gelatinized at a pH less than about 6.5.  By adjusting the pH of the suspension to between 7 and 9 after reaction with the chromium compound and immediately thereafter acidifying, preferably to a pH of 5 to 7, before filtering and drying the product is rendered capable of rapid gelatinization in hot water to give a low viscosity paste, less than about 1 per cent of the starch being rendered soluble.
