Title: Ultrasonic transmitter
IPC: H03J9/04
Filed: 1974-05-29
Abstract: 1472451 Remote control of radio and TV receivers; semi-conductor pulse generators INTERNATIONAL STANDARD ELECTRIC CORP 29 May 1974 [12 June 1973] 23728/74 Headings H3Q and H3T [Also in Divisions G1 and G4] In an ultrasonic transmitter employing an electrostatic ultrasonic transducer W for use in remote control of radio and television receivers a source of D.C. voltage in series with an impedance provides a polarizing D.C. voltage at the capacitance of the transducer W, a controllable electronic switch S, T1 is connected in parallel with the transducer and is controlled by a control signal frequency to be radiated ultrasonically by the transmitter so as to periodically short circuit the D.C. polarizing voltage and the transducer does not form part of a generator of the control signal frequency. In Fig. 1 protective resistors R1 and R2 avoid overloads or harmonic radiations. The transducer may also operate piezo-electrically. The switch S1 may be a vacuum or gas filled tube, a transistor or thyristor. The transducer W may be supplied from the D.C. voltage source U via a.coil L1, and a diode (Fig. 2, not shown) and Fig. 4. The electronic switch may be a transistor or thyristor T1 switched by the output from an oscillator (OSZ, Fig. 3, not shown), whose frequency can be influenced either capacitively, inductively, resistively or by voltage variations either continuously or in steps. The oscillator can be crystal controlled and its output can supply a divider (Tl1-Tln) the outputs from which can be electronically or mechanically switched at (S2) to the input of the transistor or thyristor T1. A pulse generator Fig. 4 may supply the transistor or thyristor T1 with pulses the repetition rate of which is selected by touching one of the finger touch sensor electrodes SE1-SE4. Touching one of the sensors SE1 causes a transistor T4 and diodes to conduct and start the pulse generator T2, T3 which stops on removing contact with the sensor SE1. Resistors R6, R7 effect initial frequency tuning of the multivibrator T2, T3. The circuit can be made with complementary transistors. The above circuits can form parts of integrated circuits. For switching on, the switching over and/or the switching off of the ultrasonic transmitter or to command or control signal frequencies arrangements according to Specifications 1,396,960; 1,412,356; 1,413,424 and 1,422,474 can be employed.

Abstract: 586,097. Brakes. CLAYTON DEWANDRE CO., Ltd., and RODWAY, J. Dec. 1, 1944, No. 24040. [Class 103 (i)] The vacuum brakes on a trailer vehicle are controlled by the actuation of pressure brakes on the tractor, and alternative means are provided whereby, if a trailer is fitted with pressure brakes, these brakes also are controllable: by the tractor brakes. As shown, the compressor 1 and pressure.reservoir 2 are connected through the driver-controlled valve 5 to the tractor brake cylinders 6. A branch pipe 8 leads to the port 17 of a relay valve 9, the function of which is to connect the vacuum reservoir 11, served by an. exhauster 12, to the pipe 13 leading to the trailer brake connection 14, in such manner. that the applied vacuum is proportional to the pressure in the tractor brake cylinders 6. The relay valve comprises a piston 18 urged, by the admitted air pressure, to the right, the piston being connected to a large piston 22 carrying a valve 26 which normally seats on the vacuum inlet. The movement of the pistons 18, 22, however, seats the valve 26 on the flange 32 on the piston 22, thereby connecting the vacuum inlet 25 to the pipe 13 which pipe is normally connected to atmosphere through the port 34 in the piston 22 and the breather 36. During a brake application, the connection between the pipe 13 and atmosphere is closed by the valve 26 seating on the flange 32. When the trailer has pressure brakes, the connection 13 is shut and the trailer brakes are operated by the two-pipe-line system 37, 39, or by a single pipe-line system 39.

Title: Improvements relating to aerials
IPC: H01Q5/15
Filed: 1954-08-20
Abstract: 781,773. Aerials. ANTIFERENCE, Ltd., and BEST, N. M. Aug. 19, 1955 [Aug. 20, 1954], No. 24346/54. Class 40 (7). An aerial arrangement for the reception of radio signals in two distinct frequency bands consists of two first aerial elements forming a dipole for the lower frequency band and two additional parallel elements for the reception of the higher frequency band each secured on an exposed part of one of the first elements. The additional elements preferably form a half-wave dipole at the higher frequency and may be attached on either side of the dipole junction-box and extend a short distance outwards from the dipole before extending parallel thereto as shown at 2 (Fig. 3). The lower and higher frequency dipoles can be backed by reflector elements if required and these need not necessarily be arranged for reception from the same direction. In a modification of the arrangement of the higher frequency elements 2 these are made L-shaped with the part of the L at right-angles to the first aerial elements #/4 long at the higher frequency. The first aerial elements in this case have an end fire array effect (Fig. 2, not shown). Figure 4 shows additional elements 2 applied to the dipole elements 1 of an X aerial. The other arms 5 of the X affect the performance at the higher frequency and are provided with cylindrical coaxial stubs 6. The length of the stub and the distance of its open end from the inner end of its carrying arm 5 are each made approximately #/4 long at the higher frequency. The stubs need not be cylindrical but may be made V or U-shaped or even as single elements (Fig. 5, not shown). In a modification (Fig. 7) the additional elements 2 are #/4 long and are secured on the dipoles elements 1 #/2 from the junction-box, the dimensions being in wavelengths of the higher frequency. This modification can also be applied to the dipole elements of an X aerial. The additional elements may be capacitively coupled to the first aerial elements through a layer of insulating material as described in Specification 745,437. Although the additional elements may be formed of rod or tube a convenient construction is shown in Fig. 6 where the element is a shaped length of semicvlindrical sheet material. The end 9 is shaped to fit the element 1 and may be secured thereto by a suitable clip (not shown).
