Abstract: 1,164,735. Adjustable mounting bracket. J. R. SIMCOX and S. H. G. JOHNSTONE. 28 March, 1968 ,[.28 March, 1967], No. 14056/67. Heading E2F. An adjustable mounting bracket has two relatively rotatable parts one 13 of which has a transverse bore 14 in which a pillar 11 is slidably received. The fixed part 13 of the mounting bracket has a screw-threaded shank 16, the base of the shank being surrounded by a cam surface 17 on the part 13. The mounting bracket also includes a movable part or element 18 which has a bore 19 through which .the shank extends with clearance. The movable element 18 defines at one end a cam surface. 20 presented towards the cam surface 17. The cam surfaces 17 and 20 are preferably complementary and can be brought into full face mutual engagement as in Fig. 2. Beyond the end face 21 of the element 18, the shank 16 is threadably engaged by a rotatable adjusting knob 22, which can be tightened to urge the movable element 18 axially into engagement with the fixed part 13. The element 18 is formed with a lug (Fig. 3 not shown) having a bore in which is slidably received one limb of a U-shaped rod 24. The adjacent ends of the fixed part 13 and movable element 18 are enclosed by a torsion spring 26 having closely coiled end portions 27 and 28. With the parts of the mounting bracket as shown in Fig. 2 the movable element 18 is wedged against the fixed part 13. On unscrewing of the knob 22 the movable element 18 is urged to rotate by the torsion spring 26 and the tip 30 of the cam face 20 rides around the inclined cam face 17 until it engages the corresponding tip of the cam face 17 (Fig. 5 not shown). If the movable element 18 is rotated so as to move the tips of the cam faces out of alignment, then subsequent tightening of the knob 22 causes the movable element 18 to rotate against the resistance of the torsion spring 26. A modification (Fig. 6 not shown) comprises two face cams on the movable element each co-operating with a respective one of two face cams associated with the fixed part, axial movement of the movable element in each direction being effective to rotate this member in a corresponding direction.

Title: Improvements in or relating to wireless signalling
IPC: H03G3/22
Filed: 1932-05-18
Abstract: 395,840. Wireless transmitting and receiving systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. May 18, 1932, No. 14174. Convention date, May 18, 1931. [Class 40 (v).] The modulation characteristic of a radio transmitter, i.e. the curve relating aerial current to modulating signal, is arranged to be of exponential form. The demodulating characteristic of the receiver is also preferably of the same form thus ensuring distortionless transmission. The exponential demodulation curve has the advantage that rectified signal strength depends only on depth of modulation so that signal strength is not affected by fading. In Fig. 3, the left-hand curve shows the modulation characteristic of a transmitter with aerial current I plotted vertically and modulating voltage E horizontally, the curve being of the form I =Ae<BE>. The right-hand curve shows the demodulation curve of the receiver, aerial current I being again plotted vertically and the rectified signal current horizontally. Fig. 4 shows a suitable transmitting circuit, in which the wave generator 1 feeds an ordinary modulator 2 receiving its signal voltage at terminals 10. The modulated output is fed to a number of amplifiers 3, 4, 5 connected in parallel but with different bias voltages applied to. their grids from a potentiometer 9. The valves have similar characteristics as indicated by the curves n3, n4, n5 displaced according to their different bias voltage ; and the resultant curve ng is approximately of exponential form. Modulating or demodulating valves may be connected as in Fig. 4 ; or a single variable-mu valve may be used. Specification 393,415 is referred to in connection with the receiving circuit, and super-regenerative reception is also referred to.

Title: Transversal equalizers
IPC: H04L25/03
Filed: 1972-03-29
Abstract: 1380651 Adaptive equalizers WESTERN ELECTRIC CO Inc 29 March 1972 [30 March 1971] 14626/72 Heading H4R In an adaptive transversal equalizer which is initially set up by transmission of a test sequence, the test sequence has the same number of bits as the number of taps on the equalizer, the equalizer is set up by correlation of an error signal derived from the difference between the equalizer output and a locally generated test signal sequence which is bit synchronized but not word synchronized with the transmitted test sequence, to derive tap gain values, and then the sequence of tap gain values is shifted around the tap attenuators until the maximum gain value is located at a reference tap position, providing equalization of the desired number of pre pulse and post pulse echoes. Preferably after reception of the test sequence the transversal filter equalizer is converted to a recirculating line and the values circulated and the correlation effected at a higher speed than normal data transmission. Fig. 1 shows an embodiment incorporating a normal tapped delay system 15 having tap attenuators 20 feeding signals to summing network 22 providing the equalizer output at 23. A difference amplifier 28 derives an error signal by comparison of the equalizer output at 23 with either a signal slicer 26 output, during adaptive operation on the transmitted signal, or the output of a test signal generator 36, providing a signal similar to a test signal from a generator 10 at the transmitter. The error signal is correlated with the signals at the delay system taps in multipliers and integrators 25, 24, to derive settings for the attenuators 20, in a normal manner. When a set of attenuator settings has been derived on a test word transmission the set of settings is cycled around the attenuators until the maximum setting is located at the reference tap, e.g. 18B. The apparatus shown can be operated in a number of ways. With switches 12, 14, and 33 on position A and 27 on B, test words from generator 10 are compared with test words from generator 36 to effect adjustment of the equalizer attenuator setting. By operating switch 14 to position B a received word in delay 15 is continuously recirculated while correlation proceeds, operation of switch 33 to position B multiplies the speed of correlation by as much as 1000. Having set the attenuator settings in the correct attenuators switch 33 can be restored to position A to resume normal data rate operation, switch 14 operated to position A to receive continuously transmitted test signals, switch 27 restored to A to cause correlation to be effected on an error signal derived between the input and output of the signal slicer, and then switch 12 restored to position B to allow normal data transmission with the equalizer continuously adapting on the received data stream. The arrangement can provide very high speed setting up, useful on polled operation of a data system.

Filed: 1962-04-16
Abstract: 1,005,217. Road traffic signalling apparatus. R. W. A. EDWARDS. April 16, 1962, No. 14670/62. Heading G4Q. [Also in Division H2] A device for indicating when a vehicle has stopped comprises two inertia operated switches and a brake operated switch series connected in an indicator circuit. Two pendulums 15, 16, the former with a return spring 31, are suspended from a further pendulum 11. Contacts 15, 19 and 20, 2] are closed and open respectively when the vehicle is stationary and are connected in series with an indicator lamp 28 (or horn) and a brake-operated switch 24. When the brakes are applied switch 24 is closed and a piston 29 moved so as to hold pendulum 11 in a vertical position. Pendulums 15, 16 will swing forward together (as shown in dotted lines) due to the deceleration of the vehicle and will remain in this position until the vehicle stops. Pendulum 15 will then return to its vertical position before pendulum 16 due to a spring 31 thus closing contacts 20, 21 and then contact 19 so that lamp 28 will light and remain alight until contacts 20, 21 separate due to the return of pendulum 16 to the vertical. Pendulum 11 may be omitted and pendulums 15, 16 suspended from a fixed member. Balls 34, 35 running in tracks 32, 33 (Figs. 3, 4) may replace the pendulums 15, 16. Each track 32, 33 is divided into conducting and non-conducting portions 41, 43 and 42, 44, respectively, the arrangement being such that the tracks and track portions are of different lengths so that when the vehicle stops, ball 34 will have returned to conducting portion 41 while ball 35 is still on conducting portion 43 so completing the circuit for light 28. While the vehicle decelerates balls 34, 35 will have rolled into position against end walls 36, 37 of the tracks. Instead of the tracks being of different lengths, one may be tilted more than the other. Pendulum 11 on which the tracks are supported may be omitted. In the embodiment of Fig. 6 two inertia-operated switches are provided by pins 60, 61 mounted on mutually insulated conductive pendulums 55, 56. When the system is at rest, pin 59 carried by a rotatable member 58 contacts pin 61 (but not 60). On stopping, because the pendulum 55 has a spring return, or a shorter period than pendulum 56, pin 59 will contact both pins 60, 61 for a short time to complete the lamp circuit. Pendulums 55, 56 may be mounted on another pendulum such as 11.
