Patent GB-1217982-A (GB)
Title: Method of controlling broadcasting receivers
Inventor: LORENZ RUDOLF
IPC: H04H60/13
Filed: 1969-01-24
Abstract: 1,217,982. Radio signalling; radio receiving apparatus. GER€TEBAU HEMPEL K.G. 24 Jan., 1969, No. 4188/69. Headings H3Q and H4L. Broadcast signals are radiated from the transmitter which are characterized by distinctive signals differentiated according to programme content which are utilized in the receiver for programme indication and selection and for the control of other receiver parameters. After the receiver is switched on, pressing "start" button S causes continuous retuning from one end of the frequency band by means of capacitance diode means 8 through the discharge of capacitor C. The distinctive signals picked up are separated from the actual programme content after demodulation of the HF signal, in "distinctive signal processing" stages 6 which contain networks tuned to the various distinctive signals, connected in parallel with the output of discriminator 2 when button S is depressed. The outputs from processing stages 6 are amplified and rectified in stages 7 to indicate the programmes being offered. After a particular required programme button P 1  . . . P n  has been pressed, only the network 6 tuned to these distinctive signals remains connected to the demodulator output. A voltage is then applied to motor M which causes continuous tuning to occur: when the first transmission with the selected characteristic is reached relay A is energized to open contacts a 1  cutting off supply to motor M. At the same time the audio signal path is completed by closure of contacts a 2 , and AFC takes over the fine tuning. If the programme is not one required, pressing button W will cause relay A to release and tuning to continue as far as the next transmission with the selected characteristic. Relay B switches over the audio frequency response for the distinctive signals characterizing music or speech programmes. Band stop filter 3 connected between discriminator 2 and decoder 4 stops the programme distinguishing signals from reaching the audio circuits.

[Also in Groups VIII and XXXV] An insulating cone for the V-rings of commutators is made of a plurality of spirally arranged turns 1, 2; 3 of insulating material which are of generally V-shaped section and are adhesively secured together. The insulating material may be a bias textile ribbon of asbestos or glass fibre base previously impregnated with a synthetic resin, an oxidisable oil or mineral glue. The ends of the ribbon may be cut on the bias before use. In one device for forming the cone, Fig. 5, the ribbon is fed between the outer periphery of a rotating mandrel 6 and a knurled roller (not shown) which bears against it: so that it is forced into the V-shaped space 14 between a profile 7 on the mandrel 6 and a profile 9 in a stationary cap 8, the cap 8 being provided with a tangential slot (not shown) for the introduction of the ribbon. In a modified method, Fig. 10, the ribbon is wound on a mandrel 6 under the knurled roller 10, as before, but it is first formed into a simple cylinder which is then forced into the required shape after heating by hot-air jets 22 by means of a composite die 16, 17 and then cooled by cold air passing through ducts 23 in the mandrel 6. In a modification, a triple die is used.

[Class 7 (ii)] Oxygen, together with steam from a receiver in which the steam formed as a product of combustion is stored, is admitted during the suction stroke and hydrogen is admitted separately and under pressure at the beginning of the compression stroke. Oxygen is supplied from a reservoir b, through a reducing valve b<1> and a heated pipe f and steam is supplied from the receiver i through the pipe m, cock o and non-return valve n to the inlet valve d in the cylinder head. Hydrogen is stored in a reservoir c and passes through a reducing valve c<1>, and a rotary or other valve e on the cylinder, into the cylinder at the beginning of the compression stroke. A sparking-plug h is provided. Exhaust steam passes through a valve j, pipe k and either directly into the receiver i or through the pipe i<1> and valve w to either the atmosphere, a condenser or an exhaust turbine. The receiver may be heated or cooled by external means and may be divided into several chambers and have a compressor for varying the pressure therein. The inlet and outlet of the receiver may bo regulated either directly by the engine or by means of a governor. Water may be injected into the cylinder at the commencement of the working stroke. The reducing valves are interconnected so that the proportion of hydrogen to oxygen supplied is constant. In order that the engine may work with oil fuel instead of with hydrogen, the cock o can be turned to shut off the steam receiver and to allow air to be drawn into the cylinder. Oil fuel may be supplied through an injector p. Specification 406,748 is referred to.
