Title: Improvements in and connected with stop devices for organs and like musical instruments
IPC: G10B3/10
Filed: 1925-03-17
Abstract: 253,594. Walker, F. P., and Walker & Sons, Ltd., J. W. March 17,1925. Keyboard switches. - In an organ, a doubletouch stop-key, when operated to the first extent of depression, brings on the corresponding stop irrespective of the condition of other stops, and when operated to a further extent, cuts off the other stops maintaining the particular stop solo. When the additional pressure is relieved, the key is returned to its first depressed position. The stop-key a, which has an inclined part p bearing its label, is pivoted at b and carries a pin v maintained in connection with a source of electricity by the engagement of the point of a piece y, pivotally mounted on the pin v, in a depression x in a terminal blade w. The contact wires s, t are so bent that on depression of the key a to the first degree (in which position the key is held by a spring not shown) contact is made with the wire s to bring on the stop; while with further depression, against the action of a blade spring l with which a button k moving with the key engages, contact is also made with the wire t connected to a solenoid operating a multiple switch closing the " off " circuits of all the stop solenoids of the department. In the latter case the contact s maintains the particular stop " on," but if desired the " off " circuits of the stops may be connected through contacts which include the blade spring l so that such a contact at l is automatically broken when a key a is depressed to the second degree. In a modification, the pin v is arranged horizontally and the wires s, t vertically, and the spring l is carried by the key. In another construction, three contact wires are provided one being connected to the source of electricity, and a plate, carried by the key bridges either two or all three of these contacts.

The chamber is fed vertically by an air cylinder 2, the piston 10 of which is mounted on feed rod 4, (5) which also passes through an hydraulic dashpot cylinder 3 which exerts a damping effect on the feed, the rod passing through a slidable tube supporting the piston 21 so that the damping effect does not occur initially on movement of the rod due to lost motion between tube 20 and adjustable engagement means, nuts 25, 26, mounted on rod 4. To balance the force applied by rod 4 on the chamber on one side of the column, a second air cylinder 60 is provided on the other side of the column and is connected to cylinder 2. The upper and lower ends of the hydraulic cylinder 3 are interconnected by two passageways, only one of which is shown in Fig. 2, one for each direction of flow and the flow in each may be throttled by adjustable tapered screw 36. The operation of the air cylinder is controlled by a "float" valve, Fig. 4, having an air inlet port 70 communicable with either of ports 71, 72 leading to opposite ends of cylinder 3- see Fig. 3-depending on the position of "float" 75, which has circumferential grooves and O- ring seals 76, 77, 124, 125. The ports 71 and 72 are also communicable, depending on the "float" position, with exhaust ports 120, 121. To shift the "float" 75, air can be introduced to the ends 78, 79 of the float channel 74, by passages 80, 81 leading from an arrangement of valves 93-101 which are primed by the same air supply valve 91 as supplies port 70. Valves 93 and 99 are manually operated to lower and raise respectively the air piston and hence the chamber 47. For automatic raising operation, valve 97 is operated and primes a control valve 101 which, in Fig. 1, comprises a valve 108 operated by a top nut 110 on rod 4 so that at the maximum required extension of rod 4 downwardly valve 108 is operated by lever 109 -acted on by nut 110-to raise the rod. For automatic lowering operation, valve 95 is operated to prime a poppet valve, not shown, in passageway 80 which is operated by the nut 26 on rod 4 when the rod reaches its uppermost position.  Alternatively, both ends 78, 79 of float channel 74 may be supplied with air by valves in the passageways 80, operation of one or other of the valves causing movement of the float.

Filed: 1972-02-22
Abstract: 1378689 Vehicle monitoring system SPERRY RAND CORP 22 Feb 1972 [12 March 1971] 8047/72 Heading G4H [Also in Divisions H3 and H4] A vehicle monitoring system for signalling at a central station the presence of co-operating vehicles at predetermined locations comprises a transmitter at each location which continuously emits EM pulses at a pulse repetition frequency unique to its location, a receiver carried by each vehicle to derive a measure of the frequency of the received signal, and a transmitter mounted on each vehicle to transmit a representation of the frequency measure to the central station so as to identify the vehicle location at the moment of transmission. The location transmitters may be incorporated in lamp posts at suitable street corners, Figs. 1, 2 (not shown); they employ transmission line systems for propagating TEM waves (see Divisions H3-H5). Signals from such a transmitter are received by an omnidirectional bicone antenna 8 on the roof 6a of a vehicle and fed via a highpass filter 65 to a detector circuit comprising a tunnel or other suitable diode 69; each incoming signal pulse causes the diode to become highly conductive. Current pulses of greater amplitude and longer duration than the input pulses are generated by the diode and fed to a monostable circuit 70; pulses from 70 pass through a gate 72 to a counter 73, the trailing edge 71 of each pulse serving to reset diode 69 for the next pulse. Gate 72 is opened for a predetermined time at regular intervals by an interrogator 78 (a pulse generator operated by a clock signal, by the vehicle operator or by a command signal from the central station), and the pulse count accumulated in 73 is directly transmitted to the central station by the vehicle voice radio communication link, or fed to an encoder 74 which causes transmission of a pulse coded signal which automatically identifies the particular vehicle as it reports its location.
