Title: Electrical musical instrument
Inventor: ANDERSON WALTER JOSEPH
IPC: G10H1/043
Filed: 1958-08-15
Abstract: 889,364. Electrophonic musical instruments. CHICAGO MUSICAL INSTRUMENT CO. Aug. 15, 1958, No. 26328/58. Class 88 (2). A keyboard instrument using twelve tuned oscillator circuits as tone generators is provided with means for rapidly lowering the frequencies of the generators and thereafter restoring them to the original tuned frequencies, producing the effect of slurring up to the notes from below. As shown, the pitch of generator T1 (which is activated under the control of key-switch K1) may be flattened by connecting condenser C3 across its tank circuit. This is effected by firing a diode formed by cathode K and electrode A1  through the application of potential B + by means of a pedal GS1 or a pedal GS2, the latter producing only a temporary flattening during the charging period of condenser C20. If switch S5 is closed, any note played is automatically, flattened for the charging period of condenser C5.

Title: Improvements in or relating to frequency control arrangements
Inventor: CAMFIELD GORDON JAMES
IPC: H03L7/10
Filed: 1949-10-20
Abstract: 696,120. Automatic control systems for oscillators. MINISTER OF SUPPLY. Oct. 12, 1950 [Oct. 20, 1949], No. 27010/49. Class 38 (iv). The frequency of an oscillator is automatically regulated by a motor-operated condenser and a reactor valve which are operated by the output of a phase detector to which the output of the oscillator and a reference signal are supplied. When the frequency difference between the oscillator and the reference is larger than a given value the motor is driven by the output from a tuned circuit supplied from the oscillator alone. As shown, the oscillator O is tuned by the reactor valve V and condenser C which is positioned by the motor M. The motor controller MC is supplied from both the phase discriminator and mixer, PD, through the rectifier R, and from the tuned circuit TC. The inputs to PD are from the reference oscillator RO and the main oscillator O through the superheterodyne circuit H. Specification 592,835, [Group XL], is referred to.

Title: Semi-automatic motor driven lens focusing mechanism
Inventor: HENRIKSEN ELMER CARL
IPC: G03B13/20
Filed: 1969-05-28
Abstract: 1,208,388. Lens focusing mechanism. BELL & HOWELL CO. May 28, 1969 [June 7, 1968), No. 27016/69. Heading G2A. A camera has an objective lens assembly 14 which is movable axially to adjust the focus, and a pendulous member 50 which can swing under gravity to an angular aspect corresponding to the focal distance, which movement actuates means for moving the lens to a focused position. As shown, the pendulous member 50 swings freely under gravity about a pivot 52, Fig. 2 (not shown) at one end. Its other end moves as a wiper across a resistive element 54, so that it acts as a variable resistor, the resistance depending on the angle of inclination of the camera. As shown, the camera is sighted so that the optical axis 28, as reflected by mirrors 34, 36 into the viewing opening 20, is aligned with the base of the subject 24, the camera also including a reference mark 38. This sets the variable resistor 54 to a particular value depending on the inclination of optical axis 28, i.e. the distance of subject 24 from the camera. Movement of the lens is controlled by the circuit of Fig. 2 (not shown), which includes a battery as a power source, and a motor. When a switch 80 is closed, the motor is energized to operate for a set time, determined by a timing section of the circuit, after which it is switched off. During this period it drives the lens axially to adjust the focus, determined by the position of the pendulous member 50 on resistor 54. Fig. 3 shows how the motor drive is transmitted to the lens system. A control lever 110, pivoted at 116, can occupy three positions. In its upper (broken line) position, it closes the switch 80, so energizing the motor 30, which has a drive shaft 132 and pinion 134. The pinion engages with a gear section 138 formed on the lens barrel 16, so rotating it and thus causing axial adjustment to focus the lens. When the motor is switched off, lever 110 is returned to its intermediate ("off") position (full line), and the lens remains in focus. When the lever is moved to its lower "re-set" position (also in broken line), it engages a lug 130 which pivots the motor anticlockwise, thus disengaging pinion 134 from gear 138. This allows the lens to be rotated back to its "start" position by a spring 146.

Abstract: 1,139,652. Valves. G. A. GILLBERG. 12 June, 1967, No. 27046/67. Heading F2V. A water tap comprises a casing 1, a cap 3 screwed into the casing and accommodating a valve member 5 axially displaceable towards and from a valve seat, an actuating screw 7 turnable by a handle 17 and imposing axial displacement upon the member 5, and a spindle 12 forming a connection between the handle and the screw, the spindle after overcoming an initial resistance being axially displaceable by a force applied to the handle whereby claws 19, 20 may be brought into engagement with each other by the axial displacement of the handle so that the cap may be screwed into or out of the casing. The initial resistance is provided by engagement of a circlip 13 with a portion of the screw 7 above a shoulder 11. Hexagonal portions of the spindle slidably engage a through hole in the screw 7 and are recieved in a socket 16 in the handle 17 to which the spindle is additionally secured by a screw 18. A locking ring 15 prevents complete withdrawal of the spindle from the actuating screw which is held against axial displacement by flanges 8, 22 and by a circlip 9 during normal operation of the valve.

Abstract: 279,822. Esau, A. Oct. 29, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Drawings to Specification. Aerials; fading, preventing; undesired signals, eliminating or limiting. - In order to prevent fading effects due to interference between the free and earthbound components of the radiated wave, two or more earthed and individually non- directional aerials are arranged in the same plane, and are spaced apart by a distance equal to or less than one-half the wavelength employed. The radiation from such an aerial system is stated to have a flattened characteristic, the space-wave component being eliminated. The system can be applied to prevent interference from a nearby transmitting station by suppressing the spacewave component of that station. It will also obviate errors in direction-finding due to interference between earthbound and reflected space waves. The spaced aerials are used for reception as well as transmission.

Abstract: 429,727. Electrically - actuated valves. ELECTROFLO METERS CO., Ltd., Abbey Road, Park Royal, London.-(Republic Flow Meters, Inc. ; 2240, Diversey Parkway, Chicago, U.S.A.) Sept. 20, 1934, No. 27122. [Class 135] [See also Groups XXXVIII and XXXVII] In a relay mechanism for amplifying small movements a tactor, periodically raised and lowered, co-operates with the sensitive element so as to control the amount of movement of the tactor in accordance with the movement of the sensitive element and consequently position a selector which selects a path of movement of a power-operated member and thereby operates one of a plurality of elements which effect a control. As shown, the tactor 32 is oscillated by a bell-crank lever 36 from a power-driven cam 38. The bell-crank lever is connected to a selector plate 46 and the amount of movement of the plate 46 is determined by the position of the sensitive element 28 relatively to the tactor 32. The selector plate 46 is adapted to position the pin 56 selectively in one of the guideways of the stationary guide plate 58, the pin being reciprocated by the crank 54 so as to operate one of the levers 60. The levers 60 co-operate with an inclined member 72 on the pivoted control lever 74 in order to operate the control member into different positions according to the lever operated. When operated the lever 60 is maintained raised by spring controlled latching means 64. As shown the relay mechanism is employed for regulating the flow through conduit 12 in accordance with the flow in conduit 10.

Abstract: 174,134. Taggart, J. Scott-, and Radio- Communication Co., Ltd. Sept. 30, 1920. Vacuum tubes.-The electron current from the cathode of a thermionic valve is distributed between two anodes and the external circuits are arranged so that when one anode potential is - raised the current thereto is decreased owing to the electron stream being partially diverted to the other anode, the potential of which is also increased. Negative resistance effects are thus produced in the circuit of the first anode, the circuit of the second anode being subsidiary and inoperative. Preferably the circuit of the second anode includes an ordinary thermionic valve, the grid potential of which is varied by the E.M.F. applied in the first anode circuit. As shown, the valve V<1> has a cathode F disposed between two anodes A<1>, A<2>. Preferably the filament temperature is so adjusted that the whole available supply of electrons is utilized. The anode A<1> is placed closer to the cathode F than the anode A<2>, which is preferably of smaller dimensions. Specification 166,260 is referred to, and the use of valves having unheated cathodes is disclaimed.
