Patent GB-1053154-A (GB)
IPC: G01N15/06
Abstract: 1,053,154. Sampling gases. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb.25, 1965 [March 5, 1964], No. 8214/65. Heading G1B. A device for taking samples from the atmosphere at different altitudes comprises a nacelle 1 which may be secured to an aircraft and from which projects an air-intake horn 6 leading through a filter to a compressor 8, a further compressor 14, and then to a distributor 17 leading by way of a valve (not shown) to a selected one of a series of air cylinders 18. The filter is in the form of a filter cartridge, as 12, disposed in a band controlled by a step-by-step rotary control system 10. Each cartridge 12 Fig. 3, (not shown) comprises a heated metal corical member to melt any ice particles surrounded by an annular chamber filled with silica gel to absorb the water. An altimeter control is provided in the aircraft so that the pilot can select, a desired altitude. When this altitude is reached, the barrel 9 is rotated to bring a fresh filter cartridge 12 into the air flow and to direct the air into a selected air cylinder 18. When the desired pressure in the cylinder has been reached, the compressors 8, 14 are switched off and a signal lights in the aircraft, to enable the pilot to set another desired altitude. In the subsequent analysis, both the contents of the air cylinder and the corresponding filter cartridge are utilized. A generator 3 driven by a propeller 4 is ponded to power the compressors and other equipment in the nacelle 1.
Patent GB-1053176-A (GB)
IPC: B66C1/24
Abstract: 1,053,176. Cradles for lifting sheets of material. GREATER IOWA CORPORATION. June 30, 1965 [Aug. 3. 1964], No. 27733/65. Heading B8H. A lifting frame for sheets of material comprises a frame 14 with tines 18, 23, which is pivoted about a pin 52 to a supporting frame 46. Spring-loaded locking-pins 54, 56 may be withdrawn to permit the frame 46 to be rotated through 270 degrees to the position shown in Fig. 11 (not shown). The frame 46 comprises three pairs of telescopic members, Fig. 6 (not shown), to which is pivoted a carriage having limited sliding movement and means for attaching it to a lifting device. The tines 23 may be removed and replaced by straight tines 28, Fig. 13 (not shown). In addition, extension arms 34, provided with tines 40 and supporting chains 42, may be attached to stubs on the main frame. The tines 18 may be provided with flanged cover-plates 20.
Patent GB-1053308-A (GB)
IPC: G01S1/40
Abstract: 1,053,308. Aerials; radio navigation. STANDARD TELEPHONES & CABLES Ltd. June 26, 1964 [June 29, 1963], No. 26500/64. Headings H4A and H4D. Relates to radio direction finding and beacon systems utilizing the Doppler effect by cyclically connecting one or more of a sequence of dipole aerials in a circular or linear array thereof to a receiver or a transmitter. Generally only one dipole aerial is operative at a time, the other dipoles in the array then acting as parasitic elements and so distorting the desired circular radiation pattern that errors arise in the system. According to the present invention each dipole aerial consists of parts 3 ... 8 connected as shown to diodes 9, 10, 13, 14 and inductors 11, 12, 16, 17. The dipole is coupled to the R.F. source or sink via balun 15 and switching voltage for the diodes is applied at terminal S; when the switching voltage is positive a #/2 dipole ensues, Fig. 2 (not shown), but when it is negative the dipole is effectively sub-divided into four #/8 parts, Fig. 3 (not shown), thereby reducing the distortion of the circular radiation pattern.
