Title: Improvements in or relating to lock keys
IPC: E05B19/22
Filed: 1929-09-09
Abstract: 339,648. Brown, J. Sept. 9, 1929. Keys and key pins.-A key of the kind showing an indication whether it was last used to lock or unlock, is prevented from giving a wrong indication on careless manipulation by a clutch device engaging the indicating member. Figs. 1, 3 show the key on completion of the locking and unlocking movements respectively, Fig. 2 showing an intermediate position. A member 5 rotatable in the key barrel 1 but prevented from moving longitudinally by a pin 5<a> has a tongue 7 engaging a slot in the key pin 8 of the lock, and a tongue 6 serving as one member of a clutch. Tongue 6 co-operates with a slot having an inclined face formed in the adjacent end of an indicating member 4 rotatable in the key barrel. Clutch engagement is effected by a spring 9. Member 4 bears suitable indications one or other of which is exhibited through a slot, not shown, in barrel 1. Rotation of member 4 is limited to a half-turn by a pin 3 engaging a slot 2. Alternatively, the clutch may be provided at the right hand end of member 4. In this form tongue 6 is omitted, and a member 4 rotates on an extension of member 5 which passes through and projects beyond the end of member 4. The projecting portion is non-circular and has slidably mounted thereon a toothed member engaging corresponding teeth on the right-hand end of member 4 under spring action. The adaptation of the invention to stem keys is also described, the members being rotatably mounted on the stem.

Title: Electric automatic control system
IPC: H02M7/515
Filed: 1962-07-17
Abstract: 1,007,969. Converting. GENERAL ELECTRIC CO. July 17, 1962 [July 17, 1961], No. 27429/62. Heading H2F. [Also in Divisions G3 and H3] In an automatic control system, a corrective action is produced by a master oscillator and a slave oscillator having outputs which are displaced in phase in dependence upon an error signal. As shown in Fig. 1 the control system is applied to a frequency converter employing inverters, e.g. of the silicon controlled rectifier type, and providing a single phase output of one frequency from a polyphase input of another frequency. The polyphase input passes through a rectifier 10 and a filter 12, and the resulting unidirectional potential is applied to identical inverters, 16, 18, the alternating outputs from which are applied to a combining stage 20 and a filter stage 22 to produce a single phase output. The inverters 16, 18, produce power outputs of a chosen frequency in response to the concurrent application thereto of an input from filter 12 and an input having such chosen frequency, which latter input is derived from a master oscillator 24 connected to inverter 16 and a slave oscillator 26 connected to inverter 18. A regulated voltage supply for the oscillators, which regulated supply determines the chosen output frequency of the system, is derived from a magnetic amplifier 30 supplied over a transformer 28 from one input phase, the amplifier 30 being controlled by an error signal produced in an element 34 which compares the output from the amplifier 30 with the output of a reference voltage source 32. An output from master oscillator 24 is applied to the slave oscillator 26 over a magnetic phase shifter 36. The system output voltage is sensed, rectified and compared in an element 40 with a reference voltage from a source 38, any error signal being applied to the phase shifter 36 which then operates so that the output from slave oscillator 26 is phase-displaced relative to the output from master oscillator 24, whereby the outputs of inverters 16 and 18 are controlled to maintain the output voltage at the desired value. In a modification (Fig. 4, not shown), the control system is applied to an arrangement having two static inverter circuits the outputs from which are serially combined. In another modification (Fig. 2, not shown), a multivibrator associated with a control unit replaces the master and slave oscillators.

Title: Outriggers for power shovels, cranes or the like
IPC: B66C23/80
Filed: 1959-08-13
Abstract: 875,857. Earth moving. THEW SHOVEL CO. Aug. 13, 1959 [April2, 1959], No. 27744/59. Class 68(1) [Also in Group XXX] An outrigger for power shovels, cranes &c. comprises a beam that is projectible outwardly and downwardly from a retracted position, the beam being supported by friction means bearing on its top and bottom sides at longitudinally spaced points so that the beam is held in its extended position without the aid of the means which project the beam. Beams 19 are accommodated side by side in a housing 16 for projection on opposite sides of the vehicle framework 2, the beams being curved so that projection brings the pivoted float 21 towards the ground. Shoes 26, 27 of friction material guide, and support the beams, and prevent upward thrust on the floats from forcing the beams back into the housing 16. The projection and retraction of each of the beams is effected by a telescopic fluid pressure cylinder comprising an outer cylinder 34 pivoted fixedly at 31 and having an annular piston which is secured to an inner cylinder 38 in which slides a second piston secured to a piston rod 40 connected at 32 to the inner end of the beam. Admission of pressure fluid, e.g. from the power steering system, first projects the annular piston, inner cylinder and inner piston as a unit, until the annular piston reaches the end of its stroke when the inner piston moves in the inner cylinder. The return of the beam is effected by admitting pressure fluid to the port 42 at the rear end of the inner cylinder 38 and a port 36 at the rear end of the outer cylinder 34. The pressure fluid is supplied to and exhausted from the cylinders by flexible hoses, the hose 43 connected to the port 42 being wound on a hose reel 58 connected by a flexible steel tape to a tension unit which tends to rotate the reel and take up slack in the hose. The hose 43 is connected to an S-bend connector tube fastened to and passing through the peripheral wall of the reel to connect with a hose coiled internally of the reel, so that as the reel rotates the coils of the hose expand or contract within the reel without binding either on the reel shaft or the reel internal wall. Swivel joints and the like are thus unnecessary: The outriggers are controllable by valves inside the vehicle driving cab and/or in the crane cab. The floats 21 are connectible to the beams in either of two positions 23, and the outriggers may lift a wheel or wheels entirely from the ground.

Abstract: 1400280 Receiver tuning circuits; transistor amplifier, oscillator mixer circuits SONY CORP 14 June 1972 [17 June 1971] 27861/72 Headings H3Q and H3T In a tuning circuit for receiving TV signals of different frequency bonds comprising a variable capacitance diode 36, 39 connected in parallel to a first inductance 34, 37, a first series circuit of an electronic band switching element 41, 42 and a second inductance 43, 45 connected in parallel to the first inductance 36, 39 and a second series circuit connected in parallel to the band switching element 41, 42 the second series circuit comprises a Q-damping resistor 48, 50 and a capacitor 47, 49 and the capacitor 47, 49 prevents direct current flowing in the Q-damping resistor. As shown a VHF RF amplifier 17, RF tuning circuit 18 and a Colpitts local oscillator 2 turned by varactor diodes 25, 36, 39 and 69. In the lower VHF band switching diodes 27, 41, 42 and 73 are non-conductive and the RF amplifier transistor 32 is coupled by transformer 34, an inductor 40 and a transformer 37 to a mixer 19. In the higher VHF band as selected by ganged waveband switches 66, 80-82 the switching diodes 27, 41, 42 and 73 are conductive to connect, additional inductances 28, 43, 45 and 71 and capacitance 29, 44, 46 and 72 so as to modify the resonance circuits to tune the receiver to the higher VHF band. The conduction of diodes 41 and 42 modifies the coupling between transistor 32 and the mixer 19. A resistor 48 is arranged so that the circuit provides constant gain when the switching diode 41 is closed or open. A switching diode 59 is forward biased during VHF reception to shunt the output impedance of the UHF tuner 13. An AGC voltage is applied at 33 to the base of the RF amplifier 32. When the local oscillator 20 is operated in the lower VHF band on output from the emitter of the oscillator transistor 63 is fed via a capacitor 77 to the mixer 19 whereas when operated in the higher VHF band an output is also taken from the base of the oscillator transistor 63 and is fed via a capacitor 79 to the mixer. This ensures that the level of the oscillator signal to the mixer is constant for the lower and higher VHF bands. A Zener diode 74 is connected to stabilize the supply to the oscillator 20. When the switches 66, 80-82 are operated to the UHF position the IF output 12 from the UHF tuner 13 is connected to the mixer circuit 19 which operates as an amplifier and the amplifier transistor 32 and oscillator transistor 63 are switched off. Also the switching diodes 27, 41, 42 and 73 are forwardly biased. As the video IF of the UHF tuner 13 is close to the channel 2 frequency the UHF tuner output is partially by-passed through the RF signal tuning circuit to reduce the frequency response of the mixer 16 when it is used as an amplifier if at least switching diodes 41 and 42 are not forward biased. -
