Title: Improvements relating to motor vehicle rear-wheel suspensions
IPC: B60G21/055
Filed: 1969-08-15
Abstract: 1,272,125. Vehicle suspensions. DAIMLERBENZ-A.G. 15 Aug., 1968 [16 Aug., 1968], No. 40876/69. Headings B7D and B7H. A motor vehicle with independent rear-wheel suspension has trailing arms 11 (Fig. 1) pivoted at 14 to a transverse member 12 which is secured to the vehicle superstructure by two spaced resilient elements 18, 18 arranged in front of the wheel axes, so that the member 12 is capable of pivotal movement, in response to lateral forces on said superstructure, about an instantaneous centre 20 behind the rear wheel axis and which lies in the median vertical plane of the superstructure. Elements 18 are resinently deflectable along axes 19a, and may also turn about those axes whereby the member 12 can turn about its axis to provide longitudinal springing of the wheels. Further elements 17 are resiliently deflectable transversely of their axes. During acceleration of the superstructure relative to the wheels, e.g. when cornering, this arrangement permits the member 12, and hence the wheels, to turn about the point 20 whereby understeer and greater stability are said to result. In another embodiment (Fig. 2) a further resilient element 29 is provided at the point 20 and at the end of an arm 23a of member 23 to which trailing arms 21 are pivoted at 22. The element 29 is substantially non-resilient transversely of the vehicle, but is resilient longitudinally thereof. In this embodiment, resilient elements 25 have arcuate recesses 26 permitting their deflection only along lines joining the midpoints of the recesses. In both embodiments a torsion rod 9 may be provided, and the trailing arms have coil-spring connection with the superstructure.

Title: Improvements in or relating to adcock aerial installations
IPC: G01S3/08
Filed: 1959-12-08
Abstract: 862,151. Radio direction finding. TELEFUNKEN G.m.b.H. Dec. 8, 1959 [Dec. 13, 1958 ; Feb. 5, 1959], No. 41685/59. Class 40(7) In order to provide an Adcock directionfinding installation effective over a wide frequency range two Adcock aerial systems having different base lengths are arranged concentrically. Errors due to the effect of the outer system elements on those of the inner system are avoided, according to the invention, by providing twice the number of elements in the outer system as there are in the inner system and positioning each inner system element on the line bisecting the angle subtended at the centre by an adjacent outer aerial pair. The errors due to the two members of the pair acting as parasitic elements cancel at the inner aerial element. For directionfinding the two elements of each outer aerial pair are connected in parallel. Fig. 2 shows an installation having six inner system elements 10-15 inclusive evenly spaced round a central receiving installation 16 and coupled to it, as indicated for element 11 only, at 17. The outer system elements 18-29 inclusive are also evenly spaced round the central installation at a greater radius and, as indicated for the elements 10, 18 and 19, each inner element is angularly mid-way between a pair of outer elements. The parallel connection between a pair of outer aerial elements is indicated for elements 24, 25. The elements of the aerial system not in use at a given time are advantageously grounded and the feeders disconnected at both their ends. Instead of disconnecting the feeders, they may be provided at the aerial element ends with filters rejecting the frequencies accepted by the other system and at the receiver end with an impedance matching termination. Fig. 3 shows this form of coupling for a typical outer system element designated 30. The element is coupled to ground through a parallel tuned filter circuit 31, 32, 33 and the primary of coupling transformer 34. The feeder from the transformer secondary provides one input to a combining circuit 36, also fed from the other element of the pair, and the combined output is passed to co-ordinate transformer 37. The cartesian coordinate output signals may be fed by switch 40 to a cathode-ray tube indicator 43 or, when this is connected to the other aerial system, to dummy load resistors 44. The switches may also be arranged to enable the aerial systems each simultaneously to feed its own direction-finding receiver.

Abstract: 936,449. Binaural systems. TELEFUNKEN G.m.b.H. Dec. 15, 1959 [Dec. 15, 1958], No. 42512/59. Class 40 (4). In a stereophonic reproducing system including two stereophonically associated amplifiers, low-frequency components of left and right hand signals are applied to one of the amplifiers together with high frequency components of one of the left and right hand signals, while only the high frequency components of the other of the left and right hand signals are applied to the second amplifier. Low frequency components or signals are audio frequency signals up to about 300 cycles/second. A cabinet houses a monaural radio receiver D, Fig. 2, and a stereophonic pick-up P. Stereophonically related signals from pick-up P are applied successively to preamplifiers V, to ganged switches S1, S2, to ganged volume controls L and to intermediate amplifying stages N1, N2. Low and high frequency signals from stage N1 are applied to output stage E1 Low frequency signals from stage N2 are applied by low pass filter F T  to output stage E1 and high frequency signals from stage N2 are applied by high pass filter F H  to output stage E2. Stage E2 has a lower power rating than stage El. Switch S1 may be set to pass monaural radio signals and provision may be made for passing such signals also through switch S2. The cabinet may house a loudspeaker H, Fig. 3, which may be connected to - either output stage as desired whereby, if the receiver is to be used only for monaural reproduction, loud-speaker H is connected to output stage E2. If subsequently the stereophonic facility is required, the loud-speaker is connected to output stage E1, a separate loud-speaker H2 being then connected to output stage E2. A receiver, Fig. 4a, having spaced high frequency loud-speakers H1, H2 has filter circuits which may be switched for feeding the low frequency signals of one channel into the output stage of the other channel, whereby the arrangement of Fig. 4b or 4c may be used. In these arrangements loud-speaker H2 receives only the high frequency signals of one channel while the high frequency signals of the other channel and the low frequency signals of both channels are received by main loud-speaker T12H1 and, if desired, by one or two loud-speakers h1. Alternatively the low frequencies may be handled by the main loud-speaker and the high frequencies by one or two high frequency loud-speakers h1.
