Title: Improvements in doors for pressurized fuselages of aircraft
Inventor: WILMER MAURICE OLIVER
IPC: B64C1/14
Filed: 1958-07-04
Abstract: 868,390. Closures for resisting fluid pressure. VICKERS AIRCRAFT HOLDINGS Ltd. June 9, 1959 [July 4, 1958], No. 21523/58. Class 123(1) [Also in Groups XXV and XXXIII] The door and door frame of a pressurised aircraft cabin are each provided about its periphery with a set of spaced lugs, the arrangement of the lugs being such that when the door is closed and the cabin pressurised the lugs on the door abut their outward faces against the inward faces of the lugs on the door frame to positively resist outward pressure on the door, means being provided, operable from within the cabin, whereby after decompression thereof, the door can be raised with respect to the frame to disengage the abutting faces of the opposed lugs, the door lugs being moved to positions intermediate the frame lugs, permitting the door to be opened. The door 10 fits within a frame 11 upon a main hinge 13 so constructed that, under the restraint of a pivoted tie member 26, the door in opening moves bodily outwards from the cabin. The door is connected to hinge 13 through a parallel linkage 21 which permits vertical movement of the door when an operating handle 18 projects spring loaded feet 19 in the base of the door into contact with a sill member 111. During such vertical movement the door is guided at its upper end by spigots 23 which engage slotted plates on the door frame. The door is provided on its peripheral edges with lugs 14 which, when the door is closed, cooperate as shown with matching lugs 15 on the door frame whereby pressure loads on the door are reacted directly by the frame and not the hinge and latching mechanism. The final latching movement causes locking spigots 16 in the door to project into holes in the door frame. Initial movement of handle 18 withdraws such latches and then causes feet 19 to project on to the sill and raise the door to a position in which lugs 14 can pass between lugs 15 when the door is opened. A conventional pressure seal is provided.

Title: Improvements in or relating to photo-resistors
IPC: H01H/
Filed: 1962-06-05
Abstract: 982,201. Testing photosensitive devices. LANDIS & GYR A. G. June 5, 1962 [June 6, 1961], No. 21715/62. Heading G1A. [Also in Division H1] A photo-resistor 1 is rotated in a housing 4 having a window 5 until the angle of incidence is such as to give a specified resistance change for a given intensity of the incoming light, after which the photo-resistor is fixed in this position e.g. by means of an adhesive, or thermo-setting resin. To minimize errors due to the light source not being accurately aligned with the centre-line of the window, the edges 14, 15 of the window are made parallel to the centre line, and the photo-resistor is laterally displaced so that its edge 17 comes in line with edge 15 of the window. If now the light source is moved to the right relative to windows, so that the incidence of the light becomes more normal, thus tending to increase the photo-resistive effect, part of the photo-resistive element now comes in the shadow of the edge of the windows 15, to provide a compensating decrease in the effect. The window may be provided with a tubular extension acting as a light-guide, Fig. 4 (not shown) and the cylinder may be subdivided into channels of narrower cross-section in order to enhance the light guiding effect, Fig. 5 (not shown).

Filed: 1974-05-16
Abstract: 1463101 Automatic control systems INTERNATIONAL BUSINESS MACHINES CORP 16 May 1974 [10 Aug 1973] 21725/74 Heading G3R A system parameter is sampled and if "valid" i.e. within an acceptable range, is stored and used to  control the sensed parameter. If however this parameter is "invalid" i.e. not within the acceptable range, due to a fault the sensed parameter is controlled according to the most recent stored, prior "valid" signals. In the embodiment, the parameter e.g. temperature or motor speed is sampled aperiodically and compared with the acceptable range which depends upon the interval between samples and upon a second sensed process parameter. As shown, the speed of D.C. motor 40 driving a magnetic tape capstan is measured by a tachometer 43 whose speed dependent period T between adjacent pulses is compared with a desired value Tr, to form a speed error signal. If this error falls within the acceptable range #Tr i.e. is "valid" the motor speed is controlled using the error. If however the error is "invalid" e.g. due to a temporary failure of the sensor, the motor speed is controlled by the last "valid" error as stored in hold network 55. The speed error is used to modify a speed command signal from network 56, so as to control the acceleration, constant speed or deceleration of the motor.

Title: Improvements in or relating to the production of sheets or foils of thermosetting artificial resin
IPC: B29C48/08
Filed: 1960-06-23
Abstract: A method of continuously producing films of thermosetting resin comprises feeding the resin in the A-stage of condensation between the bars of a heated grid so as to fuse it and then feeding it into a heated chamber whence it passes through a slot of adjustable width to form a film in the A-stage of condensation. As shown in Fig. 1, a block 5 of the resin is moved downwardly at a desired speed by feed rollers 9 on to a heated grid 15, the fused resin passing through the grid into a heated chamber 16. The space 17 between the block 5, the grid 15, and a cooled frame 13 insulated from the <PICT:0920804/IV(a)/1> grid by an insulating plate 14 becomes filled with the fused resin, the upper surface of which tends to solidify due to contact with the undersurface of the cooled frame 13, thus forming a seal or packing preventing the fused resin from moving upwards.  The downward pressure in the chamber 16 due to the movement of the block 5 causes the resin to be extruded through the slot 18 of adjustable width.  The film emerging from the slot 18 may be reduced in thickness by stretching it before it cools down.  The temperatures of the chamber 16 and the grid 15 may be separately adjusted depending on the properties of the resin used, and the rate of feed of the block 5 may be varied as required.  Suitable resins are phenol, cresol, melamine and epoxy resins.
