A device for parking a vehicle 3, Fig. 1, comprises a frame 1 having guide rails 2 for guiding-therealong pairs of rollers 4, 4<SP>1</SP> and 5, 5<SP>1</SP> on which rest the front and rear wheels, respectively, of the vehicle, the rollers being adapted to be driven by the vehicle wheels so as to rotate and move along the guide rails. Another vehicle may be parked below the vehicle 3, a sheet-metal cover being provided between the vehicles. The guide rails 2 may be moved to the chain-line position shown in Fig. 1, the rails carrying small rollers 6 for this purpose. Stairs positioned on one side of the frame give access to the vehicle 3. The guide rails are of U-section and carry racks 10, Fig. 3, for engagement by pinions 9 on the rollers which also carry grooved wheels 8 for co-operation with guide strips 11 on the guide rails. The ends of the rollers have discs 16 or they may widen conically to keep the vehicle wheels thereon. The axles of each pair of rollers are interconnected by fishplates 14, Fig. 4, each having a slot 14<SP>1</SP> and co-operating with a locking lug 15; the lug 15 ensures that when a vehicle is driven on to the rollers the roller 41 will move along the slot 14<SP>1</SP> until the fishplate 14 is raised to clear the lug. The pinions 9 are so coupled to the roller axles that by operation of the coupling the pinions may be made freely rotatable relative to the axles. Springs 7, Fig. 3, are disposed between each pair of rollers to bias them towards each other. The guide rails 2 may be hinged to the frame 1, Fig. 7 (not shown), and may also be hinged intermediate their length, or the guide rails may be moved horizontally, Fig. 8 (not shown), the upper parts thereof being provided with rollers which run along the frame 1. The parking space for the bottom vehicle may be below ground level. The racks 10 may be replaced by chains with which chain pinions engage or a cable drum may be disposed on a driven roller to receive a cable which is attached to the frame 1 so that when the roller is rotated it is pulled up or is lowered down the guide rails. It is stated in the Specification to be known that vehicles may be parked on plates which are lifted for another vehicle to be parked therebelow. The plates may be pivoted so as to be movable whether or not the lower parking space is occupied and the movement may be obtained either by a separate driving unit or by the transmission of the vehicle motive power. For example, a driving device for moving the plate may be driven by the vehicle driving wheels, curved guide rails being disposed laterally of the plate which is guided in the rails by wheels and the rails may have racks engaged by pinions driven by the driving device. The latter may comprise an endless belt running over rollers.

Title: Radio navigation-aiding system for aircraft
IPC: G01S1/02
Filed: 1953-11-09
Abstract: 738,945. Radio direction finding. SADIRCARPENTIER. Nov. 9, 1953 [Dec. 17, 1952], No. 30997/53. Class 40 (7). The invention relates to direction finding equipment for enabling an aircraft to be directed towards a transmitting station. Such equipment may comprise two aerials 1 and 2 symmetrically arranged on either side of the plane of symmetry of the craft, switching means to obtain by reflective action or by phase shifts in the connections two overlapping polar diagrams, and a co-operating transmitter radiating circularly polarized waves. It is pointed out that, though aerials such as 1 or 2, consisting of straight dipoles, regarded by themselves have linear polarization, when they are considered in relation to the ground plane provided by the craft the polarization is elliptical and may comprise ellipses such as A and B respectively for the two polar diagrams. Linearly polarized signals when received on the two diagrams will give a correct equisignal indication when the craft is on course provided that an even keel is maintained. But, as is explained with reference to Figs. 6 to 10 (not shown), if the craft is tilted about its longitudinal axis a correct direction indication will no longer be given. Operation with a co-operating circularly-polarized transmitter enables errors due to the tilting of the craft about this axis to be avoided though an adjustment made once and for all to take into account the characteristics of aircraft-aerial combination may be necessary to ensure that a correct-heading indication is given when the craft is directed towards the transmitter.

Abstract: 1,036,106. Transistor amplifying circuits; pulse modulator circuits. BAILEY METERS & CONTROLS Ltd. Aug. 28, 1962 [Aug. 29, 1961], No. 31102/61. Headings H3T and H4L. In a transistor modulator circuit comprising a transistor which is rendered periodically conducting and non-conducting by means of an alternating voltage applied across its basecollector electrode pair, the variation with temperature of the " offset " voltage existing in the emitter-collector path of the transistor when the latter is driven into conduction is minimized by limiting the collector-base voltage applied thereto by means of a diode network connected between the source of alternating voltage and the base of the transistor. As shown in Fig. 1 the base 6 of an overdriven amplifying transistor 5 is connected to A.C. supply 1 which latter supply is in addition rectified and smoothed over diode 2 and resistor-capacitor network 4, 3 to provide a collector bias for the transistor 5. The square wave voltage produced at the collector of transistor 5 at the frequency of the supply is fed to the base collector electrode pair of a modulator transistor 10, the base voltage of this transistor being limited to between zero and approximately one volt negative by means of diodes 11, 12. In this way the " offset " voltage appearing in the emitter-collector path of the transistor 10 is reduced to a value of approximately 1 mV. which is temperature dependent only to a small degree. In a second embodiment, Fig. 2 (not shown), the diode 12 of Fig. 1 is replaced by a Zener diode which together with a potential dividing network limits the negative excursions of the square wave form applied to the base of the chopper transistor.
