Title: Apparatus for recording and replaying music
IPC: G10H1/00
Filed: 1975-10-28
Abstract: 1509530 Recording music N K KIRK 28 Oct 1975 [19 Nov 1974] 49897/74 Heading G5X A device for use with an electronic musical instrument comprises a memory 54 for storing information corresponding to a sequence of pulses corresponding to notes played which can be subsequently output as music at a rate controlled by the timing circuit 58. In the storing mode, after a first key is activated a shift pulse is generated by the timing circuit 58 enabling shift registers 58 to record which keys are pressed, the pulse being generated after a predetermined time interval to enable chords to be set up on the keys. The tones corresponding to the pressed keys are simultaneously voiced. In the playback mode, the data in the shift registers are clocked out at a rate determined by variable resistor VR1 in the timing circuit.

Title: Digital divider circuits
IPC: G06F7/62
Filed: 1973-10-26
Abstract: 1451467 Frequency dividers ROBERT BOSCH GmbH 26 Oct 1973 [28 Oct 1972] 49902/73 Heading G4D A frequency divider comprises a counter X counting the input pulses at frequency fx; a register Y storing a divisor; an adder circuit A; a second register S and a comparator V; the comparator V compares the count in X with the value in register S and issues an output pulse (at frequency fv) each time equality is detected, each output pulse also causing the value in register S to be incremented by the value of the divisor in register Y. An output pulse is thus issued each time Y input pulses arrive at Z. In Fig. 1 only the five most significant bits of the divisor Y are used in the comparison but since the divisor is repeatedly added into registers the four least significant bits contribute to the accuracy of the division by causing the number of input pulses required to produce an output pulse to vary. Two alternative gating arrangements are described Figs. 2, 3 (not shown) for causing adder A to add in the divisor at appropriate times. The divisor Y may be derived from a second frequency (fy) by an arrangement Fig. 4 (not shown) which counts clockpulses for the period of second frequency. As explained in the Specification if high frequency clockpulses are employed and the input frequency fx is also made a constant high frequency (e.g. the same) the arrangement may be used to multiply a low second frequency (fy) such as the output of a tachogenerator by a constant.

Title: Improvements in the shaping of heavy metals
IPC: B21B23/00
Filed: 1964-12-09
Abstract: In the hot working of heavy metals such as by piercing, rolling or drawing, a lubricating and oxidation preventing powder mixture is used which forms on the hot finished workpiece a uniform anti-oxidation readily removable non-vitreous layer; the mixture comprises at least 0.5% by weight of crystalline components substantially all of space-lattice structure of which all solid components are of powder form and at least one component remaining solid during working.  Preferably the mixture includes a crystalline portion containing crystalline metallic oxides, including the oxide of the metal workpiece, which have an equal or greater affinity for oxygen than the workpiece metal and melting points above the working temperature, and another portion which is primarily crystalline consisting of substances which do not give off oxygen and have melting points close to or less than the working temperature. For drawing operations the mixture has no components which melt during working, but for other operations one or more of the components melt to render the mixture readily deformable.  In the working of steel, the workpiece metallic oxide is preferably Fe2O3 and the mixture may contain crystalline pumice powder, crystalline amosite-asbestos or crystalline blue asbestos powder.  The mixture may contain a portion of glass lubricant which form finely divided drops of liquid at the working temperature.

Title: Signals at highway crossings for high speed trains
Inventor: FREEHAFER JOHN EDWIN
IPC: B61L29/32
Filed: 1969-10-14
Abstract: 1285215 Level crossing control GENERAL SIGNAL CORP 14 Oct 1969 [18 Oct 1968] 50453/69 Heading B7N In a level crossing control system in which ordinary trains bring the highway crossing signals into operation by occupying a track circuit in advance of the crossing, the crossing signals are operated by very fast trains when an inductive device, provided only on such trains, co-operates with a similar device disposed on the track in advance of the track circuit. When an ordinary train enters the A.C. track circuit formed by transmitter 11 connected across rails 7 at point 9 and receiver 15 connected across the rails at point 10, track relay TR1 is released and via interlock apparatus 16 operates the highway signalling apparatus 17. The interlock apparatus ensures that the highway crossing signal is released when the train passes point 10 even though the track circuit controlling the crossing for movement in the opposite direction is occupied. A very fast train approaching the crossing actuates the inductive detector including coil R1 and momentarily releases relay D1 whereby the hold circuit of relay Q1 is broken and the track circuit supply is opened at front contact 12. Track relay TR1 is thus released to actuate the crossing signal. When the train reaches point 19 track relay TR2 is released, re-energizing relay Q1 which again locks over its front contact 22. This however does not affect the crossing signal because the train is now in the track circuit incorporating relay TR1 which remains released until the train passes point 10 on the track. In a further arrangement using radio transmission the inductive device on the track actuates a transmitter on the train and the received signal at the crossing again opens the track circuit to actuate the crossing signal. In addition the inductive device actuates apparatus defining two timing periods, at the end of the first of which the train brakes are applied unless a signal emitted by a transmitter which is controlled by apparatus responsive to a stalled vehicle at the crossing, is received on the train. The train transmitter is shut down at the end of the second period by which time the train has entered the approach track circuit.
