Title: Improvements in or relating to light polarizers and processes of making same
IPC: G02B5/30
Filed: 1940-04-06
Abstract: 548,759. Treating films. INTERNATIONAL POLAROID CORPORATION. April 6, 1940, No. 6259. Convention date, May 4, 1939. Drawings to Specification. [Classes 2 (ii) and 2(iii)] [Also in Groups XX and VIII] A light polarizer is formed by a sheet of an organic plastic material having oriented longchain molecules which have been rendered idiodichroic by dehydration. The term "idiodichroic" implies that the plastic derives its dichroism from inherent light absorbing properties, and not from added dyes or stains or from suspended crystalline material. In one form, a dry cast or extended sheet of polyvinyl alcohol is heated to a temperature approximating 175‹C. for from three to five minutes during which time it is extended by stretching to several times, for example two to eight times, its original length, resulting in an orientation, of the molecules and a molecular change due to dehydration, which renders the sheet coloured in the extension position when viewed through an analyser and substantially colourless when the analyser is rotated through 90 degrees. A darker extinction colour may be produced by treating the polyvinyl alcohol, either by soaking the sheet or by addition to the original solution, with a 1 per cent. acid solution, for example hydrochloric, hydrobromic, hydrofluoric or sulphuric acid in methanol. The colour appears at a lower temperature (about 150‹C.) and the polarizing efficiency is increased. The acid treatment may also be effected by soaking the previously stretched sheet, the sheet being then re-heated whilst being maintained stretched. The stretching may be effected in an atmosphere having a high percentage of water vapour, or superheated steam. To increase the impermeability of the sheet to water and increase its stability to temperature changes, the sheet may be reheated after soaking in a 5 per cent. solution of sodium chloride in equal parts of alcohol and water, which inhibits darkening of the sheet. The finished sheet may be rendered more flexible by the addition of a plasticizer, for example glycerine, ethylene glycol or formamide, preferably during treatment with the sodium chloride solution. The sheet may be laminated between glass sheets with bonding materials such as plasticized, incompletely polymerized polyvinyl acetal resin, vinyl acetate or methyl methacrylate, or directly without bonding material. Cellulosic materials may be used for the sheet by stretching them after rendering them rubbery-elastic, as described in Specification 549,668, and then subjecting the sheet to a temperature slightly below that at which charring occurs in order to develop the dichroic colouration.

Title: Gearing for the transmission of rotary or translatory movement
IPC: F16H25/06
Filed: 1946-03-02
Abstract: 636,109. Cam gearing for transmitting rotary or rectilinear motion ; differential gearing. NICHOLLS, K. H. March 2, 1946, No. 6584. [Classes 80 (ii) and 80 (iii)] In cam gearing in which positive rotary or rectilinear motion is transmitted between three relatively movable members, two of which are formed with opposed cam surfaces adapted upon relative movement to oscillate one or more connecting members such as balls or rollers freely mounted in the other member and engaging said cam surfaces, the connecting members are adapted to be oscillated in two directions transverse to each other and the general direction of movement of the cam members. Figs. 10, 11 and 12 show an application of the invention for the transmission of linear movement between cam members 9, 10 and a supporting member 11 for the connecting balls 12. Pairs of cam surfaces of wave form 9a, 10a, and 9b, 10b are provided on the respective members 9 and 10 at a phase displacement of 90 degrees. The connecting balls thus oscillate in two directions at right angles upon relative movement between the cam members and the supporting member which are mounted for linear movement in a supporting frame 112. By holding one of the three members, a reduced or increased movement is transmitted between the other two members or the device may function as a differential mechanism between three movable elements. This arrangement is shown in Fig. 14 adapted for the transmission of rotary movement, the pairs of wave surfaces being provided on opposed faces of rotable cam members and the connecting balls being supported in a further rotary member. In this rotary application the cam surfaces need not be in themselves of wave form but may be of swash plate or conic form arranged however to impart to the connecting members oscillations in the two desired transverse directions. Specifications 636,163 and 636,164 are referred to.

Abstract: 1375222 Navigational computers THOMSON CSF 11 Feb 1972 [12 Feb 1971] 6609/72 Heading G4G The position and velocity of an aircraft (e.g. in a landing aid system) are generated from two independent navigation systems respectively furnishing positional and acceleration data in two different systems of co-ordinates. As shown (Fig. 5) three acceleration or velocity vectors are supplied by transducers 11 on the A/C, in a system of co-ordinates determined, e.g. by true north, and fed to a co-ordinate transformer 2 which transforms them into a system based, e.g. on the longitudinal axis of a runway. For this purpose, the converter receives a course signal #4 from a ground radar ILM and two other signals from transducers 5 relating to A/C attitude (roll and pitch angles). The output of the transformer is fed to integrating loops 4, which also receive positional information X 0 , Y 0 , Z 0  from the ground radar ILM. The loops (Fig. 3) comprise two sets of adders and integrators 411, 412 and 413, 414 which receive acceleration data from the transformer 2 and are connected in a pair of feedback loops with a subtractor 42 which receives the positional information from the radar ILM. Output terminals connected to the input and the output of the second integrator 414 respectively furnish A/C velocity and position signals. If velocity information is supplied by the co-ordinate transformer 2, only one integrating loop is necessary (Fig. 4, not shown). The vertical co-ordinate may be supplied to the integrating loops 4 either from the radar ILM or from the A/C altimeter 7 according to the position of switch 9. This may be actuated by a comparator 10 when X 0  or of Z 0  attains a given value. The source of the acceleration of velocity signals may be a Doppler radar.

Abstract: 663,234. Aerials. BELCHER (RADIO SERVICES), Ltd., and HOWELL, E. C. June 12, 1950 [March 11, 1949], No. 6715/49. Class 40 (vii). An aerial array comprises a support member, a dipole aerial element and a reflector element carried on the support and further reflector elements carried by arms extending from the support, all the reflector elements being arranged on a parabola with the dipole at the focus. In an embodiment having three reflector elements the support member 10 carries at one end a dipole, one element, 15, of which is shown in plan. At the other end of member 10 is fixed a reflector element 19. The arms supporting the two further reflectors 20, 21 are made in the form of a single cross-piece 22 rigidly fixed to support 10 at right-angles. The separation between the dipole and reflector 19 is made an eighth of the working wavelength and it is convenient to make the distance between reflectors 20 and 21 the same value, the array being so constructed that reflectors 19, 20 and 21 lie on a parabola with the dipole as focus. The array structure may be mounted under the centre of gravity by attaching it by clamp means 33 to the top of a mast. To increase the bandwidth, reflector 19 may be made of different length to that of reflectors 20, 21, this is of particular value when signals on two adjacent channels are to be received. The dipole element may be of folded type and the dipole and reflectors fixed in their mountings in the manner described in Specification 652,456.

Title: Improvements in or relating to apparatus for actuating the control surfaces of aircraft
IPC: B64C13/00
Filed: 1945-03-16
Abstract: 612,309. Electric control systems. BRISTOL AEROPLANE CO., Ltd., and DANIELS, L. C. M. March 16, 1945, No..6736. [Class 40 (i)] In an aircraft control surface actuating apparatus, the surface may be set automatically to either of its limit positions or to a predetermined position therebetween and switch means are provided, actuated by the control surface, as it passes through the predetermined position in one direction, to pre-set the apparatus so that when said predetermined position is subsequently selected the apparatus will move the surface in the opposite direction. As shown, the control surface 2 is positioned by hydraulic motor 4, supplied through pipes 10, 11 from selector valve 9 which is fed from locking valve 12. Pressure fluid is passed from valve 12 only when the apparatus is in operation, by the action of solenoid 13. Solenoids 15, 16 determine the action of valve 9 and hence the direction of motion of motor 4. Solenoids 13, 15, 16 are energized from battery 6 through push-buttons 1a, 1b, 1c, 3 and relays 5a, 5b, 5c. When the " up " button 1a is momentarily pressed the " up " relay 5a is operated and locks over contacts 7a and the locking circuit remains closed until the surface 2 reaches the " up position when the limit switch 8a is opened by a cam associated with surface 2. Over operated selector valve relay contacts 17 the " up " selector-valve solenoid 15 is energized to set the valve 9 to permit pressure-fluid to pass to the hydraulic motor 4 from the locking valve 12, which has been opened by the energization of solenoid 13 through the closure of contacts 14a. The flap 2 is thus driven to the " up " position. A similar sequence of operations takes place when the " down " button 1b is pressed. When normally closed, stopbutton 3 is pressed, the solenoids 13, 15, 16 are all de-energized and the locking-valve 12 is spring-urged to the closed position, thereby interrupting the supply of pressure fluid to motor 4 which stops. When flap 2 passes through the "take-off" position C during movement from a to b, the selector trip switch 20 is set to connect the normally open changeover relay contacts 19c in series with the selector-valve "up" solenoid 15. Similarly, as the flap passes through position C in moving from b to a, contacts 19c are connected in series with " down " solenoid 16. Thus, when the " take-off " button 1c is pressed, " takeoff " relay 5c is energized, locks over contacts 7c, locking valve relay contacts 14c and changeover switch contacts 19c are closed and the appropriate solenoid 15 or 16 energized, through the closed contacts 19a or 19b respectively. Fluid is passed to motor 4 to move the flap 2 to the " take-off " position, at which the limit switch operates and the holding circuit of a relay 5c is opened and the apparatus stopped. In alternative arrangements, the push-buttons may be placed in the holding circuits or may actuate all the corresponding relay switches.
