Title: Control apparatus for vtol aircraft
IPC: G05D1/06
Filed: 1971-07-09
Abstract: 1329901 Automatic control of aircraft DORNIER A G 9 July 1971 [18 Aug 1970] 32350/71 Heading G3R [Also in Division B7] A control apparatus for an aircraft comprises means 68 for pre-selecting pitch angle values, a position sensing platform 3, a VTOL position controller 2, a comparator 66 and means 69 for applying pre-selected pitch angle valves to the comparator. The actual value # of the pitch angle of the aircraft 12, as measured by the position sensing platform 3, is fed to synchro 32 and used to control servomotor 38, and potentiometers 35 and 36, which feed pitch angle indicator 70 and comparator 66 respectively. The output signal from the synchro, along conductor 18, is zero, so that if the VTOL controller 2 is connected by means of switch 82, there is no sudden signal to servomotor 16, which governs control surface 8; the simultaneous actuation of switch 61 causes the feedback to the motor 38 to be through the comparator which is receiving a signal # from the potentiometer 36 and also a signal #<SP>1</SP> if such a pitch angle has been chosen by means of preselector switch 68, which may be connected to a system (90) of potential dividers, Fig.2 (not shown). Actuation of a release button 69 on the control stick 7 causes a signal (#-#<SP>1</SP>) to pass to the motor 38 which will move until its position corresponds to #<SP>1</SP>, thus producing an output (#-#<SP>1</SP>) from the synchro, which by means of the servomotor 16 causes the control surface 8 to bring the aircraft pitch to #<SP>1</SP>. When the VTOL controller 2 is disconnected a pilot operable trimming switch 50 on the control stick 7 is connected to a mechanical trimming mechanism 58; if the controller is engaged switch 56 causes any signal from the switch 50 to be fed to the motor 38, so that the pitch can be changed by the pilot until the desired valve, as shown by indicator 70, is attained. Signals from both the trimming switch 50 and the comparator are fed through an inter-lock 53 which gives a signal from the former priority.

Abstract: 819,537. Printing surfaces. NICHOLL, L. C. May 1, 1957 [Oct. 24, 1956, No. 32423/56. Class 100(2) A stereotype matrix consists of an impressed flong backed by uncompressed and uncalendered filter paper which has been applied during the making of the impression on the flong by the printing frame. The filter paper is pre-stiffened, e.g. by a solution of casein glue with or without the combination of bicarbonate of soda and/or formaldehyde,. by starch, plastic or resin adhesives. The backing is of a thickness similar to the depth of the impression made by the type forme. The matrix is produced by inserting between the plates of a press P the original type forme 1, the flong 2, the backing 3, a wire mesh sheet 4, and a rigid perforated plate 5. The purpose of the plate 5 is to allow the escape of steam during pressing and the plate 4 is provided to prevent the perforations in the plate 5 from impressing the backing sheet. The pressing operation impresses the flong 2 and attaches the backing 3 thereto. The backing fills in any recesses in the 'back of the flong so that the matrix has a smooth flat outer surface.

[Class 27] [Also in Groups XIX and XVII] In a device for delivering tickets from a continuous strip, the strip is fed to' a pair of issuing-rollers and then cut to separate the foremost portion, the ticket thus formed being fed forwardly by rotation of the rollers so that it protrudes from the front of the rollers but is held therebetween, the rollers being free to rotate forwardly independently of their driving mechanism to facilitate the removal of the ticket by the purchaser. The invention is shown as applied to a machine for printing and issuing tickets from a strip 31. Upon the insertion of a coin or coins, or the rotation of a handle, rollers 3, 4 feed the forward end of the strip to spring-pressed issuing-rollers 21, 22 and a knife 11 severs it to form a ticket 32. The issuing-rollers are driven from the feed-rollers and serve to feed the ticket to the position shown, in which its forward end projects through an aperture 29 in the casing. The manual removal of the ticket is facilitated by incorporating in the drive to the issuing- rollers an overrun device comprising pawls, 23, 24 on the rollers co-operating with ratchet wheels 25, 26 on driving pinions 13, 14.

Title: Production of sulphuric acid
IPC: C01B17/90
Filed: 1954-11-11
Abstract: <PICT:0752323/III/1> The Specification relates to improvements in the process of Specification 687,160, the latter relating to a process for the production of sulphuric acid by absorption of sulphur trioxide in sulphuric acid at a temperature higher than 150 DEG C., the hot sulphuric acid formed being cooled by means of air. According to the present improvement the fumes formed when the hot sulphuric acid is air cooled are eliminated by admixing the air containing the fumes, with the gases containing sulphur trioxide before the latter are passed to the absorption stage.  Thus as shown in the drawing, sulphur trioxide containing gases enter at 1 into a packed column 2 fed with sulphuric acid at 50 DEG C. from pipe 9. The acid leaves the column for example at 260 DEG C. by line 3, and passes to a cooling column 4 where it is cooled by air passing in through line 5.  The acid from the cooling column is pumped by means of pump 7 back through line 9 to the absorption column and is in part withdrawn as product through line 8.  The air leaving the cooling column 4 together with sulphuric acid fumes is passed through line 6 to join the incoming sulphur trioxide before the latter passes up the column 2.  The cooling air may enter at 20 DEG C. and leave, with the sulphuric acid vapour at 200 DEG C., whereby the acid in the cooling column 4 is cooled from its entering temperature of 260 DEG C. to 50 DEG C.  The water required for the process is introduced for example at 11 in the form of dilute waste acid at 20 DEG C. and effectively reduces the effluent gas temperature to 80 DEG C.
