Title: Electronic musical synthesizer
IPC: G10H1/043
Filed: 1973-02-22
Abstract: 1418737 Electrophonic musical instruments WURLITZER CO 22 Feb 1973 [29 Feb 1972] 8651/73 Heading G5J An electrophonic musical instrument comprises means for generating a plurality of tone signals, a keyboard having at least two discrete parts to control the signals, means for applying the tone signals to two parallel channels and means rendering one or other channel operative according to which part of the keyboard is played on. The output of a master oscillator, described in detail with reference to Fig. 11 (not shown) and shown as 78 in Fig. 2, at about 1À5 MHz is applied to an LSI divider chain which provides 12 outputs at semitone intervals to a network 84 and 13 outputs to network 92. Networks 84, 92 select the highest note played in their parts of the keyboard 100, 104; 102, 106, and directs the tone signal to the two channels AA<SP>1</SP> and BB<SP>1</SP>. A steering circuit 112 described in detail with reference to Fig. 12 (not shown) detects which part of the keyboard is played on and applies a signal on either lead 190 or 192 to enable either channel AA<SP>1</SP> or BB<SP>1</SP>. Channels A<SP>1</SP> and B<SP>1</SP> produce thirds of chords while channels A and B produce fifths and with further division at 144 and 162, roots. The outputs of channels AA<SP>1</SP>, BB<SP>1</SP> are applied through tone filters 136 to an output system 138, 140. The above described keyboard is provided as an additional keyboard on a conventional electrophonic organ to give the facilities of a synthesizer. Vibes, xylophone, glock and chimes are simulated by giving the high frequency components a shorter envelope than the lower frequencies. Wah-wah may be similarly provided by detuning an active filter, Fig. 9 (not shown) which includes two light dependent resistors (512, 516) lit by a tungsten lamp or light emitting diode (538) fed by an attack pulse. Delta pitch, vibrato and possibly wah-wah are provided by detuning the master oscillator either during attack or cyclicly and the synthesizer keyboard may have a "second touch" facility for bringing in the effects, i.e. there is a second switch operable by any of the keys on depression past their normal actuated position.

Filed: 1964-03-02
Abstract: 1,058,421. Automatic control of cooking ovens. BAKER PERKINS Ltd. Feb. 16, 1965 [March 2, 1964], No.8666/64. Heading G3R. A control system for an oven comprises a colour sensing device such as a photo-cell 3 for sensing the colour of a product 1 emerging from the oven, the colour of which product is dependent upon the heat treatment received in the oven 2 and which heat treatment is controlled according to the colour sensed by the colour sensing photocell 3; the system comprising a proximity detector 10 for detecting the absence of a product 1 emerging from the oven 2 whereby to exert a control on the temperature of the oven. The signal developed by the photo-cell 3 is supplied to a control device 4 to control a reversible servomotor 7 by way of a change-over switch 5 and a power supply 6, the servomotor 7 being effective to control the heat treatment received by the product 1 by varying either the supply of gas to the oven, changing the speed of the band conveying the product 1 through the oven or by altering the position of the dampers in the oven. The absence of a product 1 passing through the oven is detected by the detector 10 which causes, by way of a relay 12, the switch 5 to change its position whereupon the temperature of the oven is determined by a thermocouple 14 in the oven and a control device 13. The photo-cell device includes a white tile for setting purposes and is mounted on a carriage which enables it to scan the whole width of the product being processed. The detecting device 10 may be capacitive or inductive or sensitive to sonic beams or radiation and the system may include time delay means to render the detecting device insensitive to short absences of the product 1 being processed.

Title: Improvements in or relating to safety devices for electrical circuits
IPC: H01H85/00
Filed: 1925-04-01
Abstract: 241,458. Calor Elektrizitõts-Ges., and Dreyer, O. April 1, 1925. Thermal cut-outs.-A safety device comprises an exchangeable fuse and an exchangeable thermal releasing unit controlling the passage of current through the fuse, the fuse being so mechanically coupled to the unit arranged axially of it that the unit may be inserted into or withdrawn from the device by the aid of the fuse. The socket 1 has the same base area as, but greater height than, the ordinary fuse and contains a heating coil 17 and insulating ring 71. The coil 17 is wound on a tube 22 and is connected to the tube 22 at one end and at the other to a terminal 72 so as to reproduce approximately the heat conditions of the circuit to be protected. A threaded ring 73 receives the plug 9 containing the fuse 10 which is connected to the terminal 74 at one end and at the other to the tube 22 by the thermal releasing unit. The unit comprises a tube 30 mounted in the tube 22, and receiving the fuse contact 10<a>, good contact between the tubes being ensured by a flange 75 on tube 30. Within the tube 30 is a pin 31 pressed by a spring 32 but soldered to the tube at the groove 77. The diameters of the tube 30 may be graded to suit various current capacities and to prevent too large a fuse and unit being inserted, and in Fig. 5, is shown a large capacity device in which a shoulder 75a replaces the flange 75 of Fig. 1. In operation, the fuse and coil are in series in one lead and the terminal 34 is connected in the other, overheating melting the solder and causing the spring 32 to move the pin 31 on to the copper-plated carbon contact 33. This establishes a direct short-circuit through the fuse and blows it. To renew the fuse and releasing unit, the plug 9 is unscrewed, the unit is removed and placed on a fresh fuse, and the pin 31 is put back and, held by cooling of the device. The condition of the fuse is seen through an opening 41 and that of the unit can be observed, after withdrawal, from the position of the pin 31, it being possible for a large overload to blow the fuse without the pin being released. The internal diameter of the ring 71 is chosen in respect of the outer diameter of the flange so that a too large releasing unit cannot be inserted, and the depth of the ring is such as to prevent contact between the fuse contact 10<a> and tube 22 should a fuse be inserted without a releasing unit. The unit may be arranged to screw into the tube 22 and, for soldering, instead of an alloy, a fusible material such as colophony, cellon, or the like may be used. The terminals may be disposed behind the device and instead of grading the diameters of the tube 30 the lengths may be graded, or the units may have graded lateral cam-like means engaging recesses in the ring 71. The unit may also, alternatively, open a closed shunt circuit for the fuse, so strengthening the current through it.

Title: Improvements in water flow control apparatus
IPC: G05D7/01
Filed: 1932-03-24
Abstract: 399,179. Sprinkler valves. ELDER, D., 3, Upper Bedford Place, Russell Square. London. March 24, 1932, No. 8869. [Class 135.] Valves controlled by pilot or relay valves.-A water-flow timing-valve regulator for use, for example, in controlling the flow to garden hose sprinkler heads arranged in series, as in Specification 312,181, [Class 135, Valves &c.], comprises a valve, such as 7, Fig. 2, which is adapted to close off one passage 5 and open up another passage 12 for a predetermined time, said valve being actuated by a timing gear operated by a waterwheel projecting into the outlet passage, a visible indicator being provided to indicate at any moment the position of the timing gear. In the arrangement shown the shaft 26, Fig. 4, of the waterwheel is geared by a double-train worm gear 28, 29 and 31, 32 to a threaded worm 34, of double hour-glass form, the threads of which engage the spring-pressed telescopic chisel point 38 of an arm 37 mounted on the pivot shaft 35 of the visible indicator arm 23. After a predetermined flow the movement of the arm 37, 38 causes an auxiliary disc valve 24 to open a port 25 to supply pressure to the piston 15 which then moves the valve 7 to close off the passage 12 and open up the passage 5 to another head. In setting the indicator arm 23 to set the apparatus for a predetermined duration of flow one of a pair of pins 49 on the pivot shaft 35 operates on one or the other of two upright extensions 41 of the telescopic chisel point 38 and withdraws the same from engagement with the worm 34 so that the arm 38 and the auxiliary disc valve 24 can be moved to the setting desired. On release of the indicator arm 23 the telescopic point reengages the worm at the new setting. When all the regulators in the series have been shut off, and the water pressure in the pipe interrupted by other means, the spring 18 reopens the valve 7, and at the same time a compression spring 48 forces the piston 45 with its spindle 44 against an arm 43 on the pivot shaft 35 which is thereby rotated and withdraws the chisel point. 38 from the worm 34 and resets the indicator arm 23 against the presetting stop 54 on the visible scale 53. The action of the flowing water on the waterwheel can be varied, as required, by a pivoted blade or vane adjustably projected into the stream by an adjusting screw. A modified arrangement of the regulator is shown in which a single regulator is adapted to control the flow to a number of sprinkler heads by means of a multiple slide valve thus avoiding the need for a regulator at each sprinkler head.

Abstract: 516,562. Vehicle fittings for loading. CRISTOFOLETTI, U., LABOCCETTA, L., and PERSI, E. March 23, 1938, Nos. 8881 and 8882. Convention dates, March 24, 1937, and May 28, 1937. [Class 78 (iv)] Load-containers are hauled up ramps on to trucks by a winch, by fitting the lower end of the ramp with rollers which pass under the container and gradually tilt it as the ramp is forced thereunder until the whole container is supported on the ramp. For containers without feet, the lower end of the ramp is provided additionally with wedge-shaped surfaces or the latter may be fitted to the container itself. In some cases the ramps are formed as wheeled carriages. Fig. 1 shows one construction with a chassis 1 fitted with a roller frame 3 adjustable in inclination at point 5. The ramp 6, connected at one end to the frame 3,. carries a roller track 4, rollers 13 which are pushed under the edge of a container 10 with feet, and winch ropes attached to the container at 12. By hauling on the ropes the container is tilted and gradually drawn up the ramp. In some cases containers without feet have wedge-shaped projections at their front ends under which the ramp may get a purchase. Fig. 4 shows the ramp 6 fitted with a sliding-carriage 27 roller-guided at top, bottom and sides of the ramp. The carriage carries a pair of beaks 28 for forcing under a non-footed container until the edge 33 passes completely thereunder and forms a stop for it as it is hauled on to the ramp. The carriage may be removed before the container is hauled up the ramp 6. The roller tracks on the ramp may be covered by an endless belt to form the container support. For loading and transporting in the same apparatus these ramps may he mounted on wheels to form trailer or independent trucks. In one of these constructions side bars 14, Fig. 8, are raised 'by jacks to engage the feet of the container and lift it clear of the rollers 2 and belt 10 during transport in the horizontal position on the truck. The road wheels of these trucks may be adjustable longitudinally on the chassis. The trucks may also be provided with beaks on a sliding carriage similar to those of Fig. 4.

Title: Oscillating rake type cooling bed for rolled metal rods
IPC: B21B43/02
Filed: 1966-03-01
Abstract: 1,095,809. Rolling metals. VERWALTUNSGESELLSCHAFT MOELLER U. NEUMANN OFFENE HANDELSGESELLSCHAFT. March 1, 1966 [April 12, 1965], No. 8904/66. Heading B3M. An oscillating rake cooling bed for rolled metal rods 3 comprises stationary toothed rakes and movable toothed rakes 1 supported and reciprocated along inclined ramps 12, 13 and is characterized in that the stroke of the movable rake in the feed direction is longer than the length of the surfaces 2a of the teeth of the stationary rakes. The movable rakes 1 are carried on beams 5, 6 with support rolls 10, 11 mounted beneath them. The-movable rakes 1 are reciprocated by means of three rolls 19, 20 which are reciprocated (direction B in Fig. 2) transversely by the rod feed direction between a plate 23 mounted on the rakes 1 and a wedge 21 fixed on the ramp 13, the inclined surface 20 of the wedge converging towards the plate 23, Fig. 2 (not shown). The rollers 19, 20 abut the plate and the wedge and hence any reciprocable movement of the rollers causes the roll 11 to reciprocate along the ramp 13. The rods 3 are fed into a groove in the fixed rakes (position C), the rake 1 is moved in the feed direction and the edge 1b of each tooth pushes the rods 3<SP>1</SP> along the surfaces 2a of the teeth of the fixed rake (position D). Since the stroke of the rake 1 is greater than the length of the surfaces 2a the rods 3<SP>11</SP> fall on to the surface 1a of the rake 1 during the forward stroke and are deposited against the surfaces 2b during the return stroke after which they fall on to the surface 2a. The surfaces of the rakes may be covered with soft heat-resistant strips, e.g. synthetic material containing carbon graphite or silica. It is essential that the surfaces 1b project above the surfaces 2a by a distance greater than the radius R of the largest rods to be fed otherwise the rods could travel back over the teeth.
