Abstract: 1,123,760. Collapsible steering columns. GENERAL MOTORS CORP. 3 Aug., 1967 [15 Sept., 1966], No. 35747/67. Heading B7H. A collapsible steering column assembly comprises a tubular energy absorption member 24 which surrounds an intermediate portion of a steering shaft 20 and includes a pair of relatively telescopic tube sections 36, 38, one of the tube sections 38 having a radial protuberance 60 in interfering engagement with the wall 62 of the other tube section 36, the protuberance causing progressive deformation of the tube wall 62 on relative movement of the tube sections to resist collapsing of the assembly. As shown a number of circumferentially spaced radial protuberances 60 are provided on the tube section 38 which is supported in a vehicle by a bracket 44 with open-ended slots for the bolts, by which it is attached to a vehicle passenger compartment thereby permitting movement of the tube section 38 away from but not towards a vehicle driver. The steering shaft 20 comprises a tubular section 30 secured by crimping, to the splined ends 28 and 31 of the lower and upper steering shaft portions 26 and 32. On collapse of the column assembly the rib below the splined end 31 is destroyed permitting the shaft portion 32 to telescope freely within the tubular section 30. Between the shaft 20 and member 24 is a tubular rotatable transmission shift control member 22 comprising two tubular sections 50 and 52 interconnected by tongues 58 on the outer section 50 engaging slots in the inner section 52 to transmit rotation between the sections and by external dimples (54) (Figs. 5, 8, not shown) engaging ribs 56 on the outer section. On collapse of the column assembly the energy absorbed by the deformation of the member 24 is supplemented by deformation of the section 50 by the dimples 54.

An arc chute has two groups 50, 51 of spaced metallic plates stacked along intersecting sides of the arc chute, the groups being spaced apart to form an exhaust port 73 remote from the arc initiation point and having a relatively large venting area so that a comparatively large part of the arc produced gases will flow through the port and sweep the arc into engagement with the plates most remote from the arc initiation point. The metallic plates 53 of the group 50 are spaced by insulating strips 54 and are associated with aligned insulating plates 55. The plates 60 of the group 51 are upwardly inclined and disposed along one side of an exhaust duct 71. The switch may have two moving contacts 10 (one shown), co-operating with fixed contacts 12, 12a in narrow slots 33, 34 formed between insulating plates 37, 40, 38, the plates 37, 38 having elongated passages 43 communicating with venting pockets 42 and the plate 40 having perforations 44 to ensure the formation of arcs in both slots. The plate 40 also has slots 75 and irregular openings 76 to cause turbulence limiting the downward flow of arc gases. Magnetizable plates 67 secured to the outer side walls of the arc-chute assist the metallic plates 53, 60 in providing a low reluctance magnetic path to distort the field surrounding the arc and produce magnetic blow-out. Specification 687,886 is referred to. Reference has been directed by the Comptroller to Specification 714,979.

Title: Improvements in or relating to magnetic core recoding devices
Inventor: LYNCH ARNOLD CHARLES
IPC: H03K19/16
Filed: 1957-11-21
Abstract: 892,452. Electric selective-signalling systems. POSTMASTER GENERAL. Nov. 21, 1958 [Nov. 21, 1957], No. 36374/57. Drawings to Specification. Class 40 (1). A recoding device having g groups of w input windings and in which each incoming item of data is represented by a combination of g markings one in each group of windings, comprises wg magnetic cores (one for each item of data) each carrying g input windings and means for magnetically saturating every core, and is so arranged that when all the g windings on a core are marked the magnetization of the core is reversed whereas when some but not all of the g windings on a core are marked the magnetization is not reversed. In this way, each incoming item of data selects, and reverses the magnetization of, a single core. The cores may also carry an array of output windings in which a combination of markings will be induced when a core changes its magnetization. Radices of two and eight are mentioned as possible output radices using a decimal input radix. For the actual construction of the recording device it is suggested (Fig. 2, not shown) that as regards the output windings, each be wound with the same number of windings each having its ends brought out to a tag-board whereby the pattern of output windings can easily be changed by shorting out any unwanted windings.

Title: Improvements in or relating to instrument landing systems
Inventor: BENJAMIN JOHN
IPC: G01S1/02
Filed: 1963-09-20
Abstract: 1,088,957. Radio navigation. MINISTER OF AVIATION. Sept. 15, 1964 [Sept. 20, 1963; Feb. 19, 1964], Nos. 37200/63 and 6990/64. Heading H4D. In an aircraft instrument landing system, azimuth guidance is provided by two transmitter aerials, one on each side of the airfield runway. These provide signals which are received at the craft aerial. The three aerials may be of the horn type and have fan-like radiation patterns. The aircraft receiver incorporates a multiplying circuit having a non- linear characteristic so as to form product signals. These cross-correlation products are selected by band-pass circuits and have amplitudes depending upon the degree of time overlap of the signals received from the runway aerials. Displacement of the craft from the runway centre line affects the degree of overlap of the received signals and hence also the relative amplitude of the correlation products which are thus a measure of the craft lateral position. In one embodiment, both runway aerials transmit pulse signals, one aerial employing a single carrier frequency while the second aerial transmits simultaneously on several frequencies. Each of the different carrier frequency pulses have different profiles and automatic gain control is provided from the centre frequency cross correlation product. In a second embodiment, the frequencies transmitted by each aerial are chosen so as to give maximum signals at the receiver when the craft is situated at one or other of the runway edges. In a third embodiment, pulse modulation of the carriers is replaced by modulation from a thermal noise source. Delays are introduced at the transmitter to cause peaking of these cross-correlation products at the sides of the runway and at the centre. The receiver may be modified so as to guide the craft along a curve path and the transmitter aerials may be mounted either one at each side of the runway, together on the same side or one above the other to give guidance in glide path.
