Title: Interrogated transponder system
IPC: H04N7/173
Filed: 1964-08-04
Abstract: 1,067,469. Radio-frequency systems. SKIATRON ELECTRONICS & TELEVISION CORPORATION. Aug. 4, 1964 [July 24, 1963], No- 31108/64. Heading H4L. [Also in Division G4] The invention provides a transponder system, e.g. a subscriber television system, in which interrogation signals are re-coded at the transponder to indicate the condition of apparatus monitored by it and are returned to the central station. In one embodiment comprising 4032 transponders a group of transponders is selected by transmitting from a central station four frequencies chosen from nine, a sub-group within this group being selected by subsequent transmission of a single frequency chosen from the four first sent. The sub-group contains 8 transponders which next receive a series of interrogation pulses formed of repeated sequences of the other three frequencies of the four first sent. During the interrogation cycle the single frequency is maintained so that the 8 transponders respond to the interrogation pulses. Each transponder includes a switching unit which recodes the interrogation pulses and may comprise rotary switches, a gate, and an inverter, Figs. 5 and 6 (neither shown), the switches being coupled to a television receiver station selector switch for example. The recoded pulses excite a transistor ringing circuit,  each transponder in a sub-group having a different ringing frequency so that when the  pulses are returned to the central station the transponder pulses can be identified and fed to the appropriate section of a billing unit, for example. The selecting signals may be transmitted sequentially instead of simultaneously, in which case they are repeated several times and the transponder selective circuits are slow to release. To provide for error detection 1 bits may be transmitted to the transponders as 010 and 0 bits as 101. The central station then includes a look-up table comprising all the possible forms that these signals may take as a result of the recoding and compares each returned sequence with the table. If an error is detected the central station interrogates the transponders several times, closing down if no correct response is obtained. If no error is detected the central station is so programmed that it automatically selects the next sub-group of transponders. In another embodiment, there is no ringing circuit in the transponder. Instead the 8 frequencies corresponding to the transponders are sent from the main station and each transponder selects a different one of these as carrier for the recoded pulses. A further embodiment, Fig. 9 (not shown), is used in restricted band transmission. Selection is made by means of only two frequencies, followed by one frequency, and the interrogation by pulses of only one frequency.

Title: Improvements in or relating to steering gears for road vehicles
IPC: B62D3/02
Filed: 1947-11-25
Abstract: 641,366. Bowden mechanism. BISHOP, R., and JOHNSON, R. H. Nov. 25, 1947, No. 31214. [Class 80(iii)] [Also in Group XXXI] A road vehicle steering gear comprises a series of separate contacting rolling elements. such as rollers, for converting rotary movements of the steering shaft into reciprocatory movements of the track rod. The steering shaft may carry impeller means to feed the elements into a guide channel formed in the track rod and having an abutment or abutments located therein. The guide channel may have two legs extending in opposite directions along the track rod to terminate in abutments on the rod or as shown the guide channel may have two U-shaped runs each extending from the point of entry of the elements towards an end of the rod and back again to terminate in a common abutment on a part in relation to which the rod is displaceable. The track rod is universally jointed to links 3 connected to each of the steerable wheels and is of rectangular section to slide within a housing 2 connected to the vehicle chassis and the end portions of the rod may be enclosed in bellows. The rod 1 is formed of side plates 1a, 1b and filler pieces 1c, 1d, 1e, thus forming channels 4 which are joined by a common abutment 12 secured to the housing 2. The abutment 12 has outwardly and downwardly extending faces 12a and is adjustable by a set screw 13. The channels 4 are blocked from interconnection by a filler member 5 of an auxiliary housing 6 which is formed with channels 7 interconnected by a cavity containing a toothed impeller 9 on the steering shaft 10. The teeth of the impeller 9 engage the neck portion of the dumb-bell shaped rollers 11. The ends of the rollers 11 are formed with part spherical surfaces to provide point contact with adjacent rollers and the channel surfaces. The rollers 11 are formed in series in the channels 4, 7 so that movement of the impeller 9 is transmitted to a thrust on the appropriate side of the abutment 12 with consequential movement of the rod 1, and the channels 4, 7 may also be filled with oil or grease. The rollers can be preloaded by means of springs 15 within recesses 14 in the filler member 1d, by a spring between the abutment 12 and the set screw 13, or by a spring between the final roller at one end of the series and the abutment 12.

Title: Improvements relating to the Watering of Potted Plants.
Inventor: BAGGALEY THOMAS HENRY
IPC: G05D22/02
Filed: 1966-07-12
Abstract: 1,172,812. Automatic moisture control. T.H. BAGGALEY. June 26, 1967 [July 12, 1966], No. 31290/66. Heading G3R. A potted plant is automatically supplied with a predetermined quantity of water when that supplied by a previous operation has evaporated. This is effected by the apparatus shown, which comprises a conventional horizontal beam weighing machine 1 modified by the addition of a micro-switch 16, a main switch 23 and a ball bearing 10 movable along the beam 3 to a position determined by the insertion of a pin (13) in a selected one of a number of holes 14 in the beam, the switches 16, 23 being series-connected with the operating coil of a solenoid valve 21 controlling the main water supply pipe 20 feeding the potted plant 18 through an auxiliary pipe 19. To set up, the ball bearing 10 is retained by the pin (13) in a neutral (weight) position and a counter-weight 6 is moved along the beam 3 to balance the weight of the potted plant 18 and maintain the beam 3 in a horizontal position set by pointers 4, 5. The pin (13) is then inserted in a hole 14 corresponding to a desired weight of water to be supplied, the holes 14 being calibrated for this purpose. Next the beam 3 is manually depressed so that the bearing 10 rolls to its selected position, causing the beam 3 to close the micro-switch 16 through its operating finger 17. Switch 23 is now closed to energize the valve 21 and cause water to flow into the pot 18 whose increasing weight causes the beam 3 to rise until the bearing 10 rolls back to its neutral position, thus allowing switch 16 to open and causing the valve 21 to shut off the water supply. As the water evaporates the beam 3 sinks until, when it is below the horizontal, the bearing 10 rolls back to its selected position to repeat the above cycle. The pipe 20 may supply a large number of potted plants whose watering is controlled by the valve 21 in accordance with its operation for the representative pot 18.
