Title: Remote Control Mechanisms
IPC: F16H59/04
Filed: 1967-11-10
Abstract: 1,192,057. Change-speed control. FORD MOTOR CO. Ltd. 10 Nov., 1967 [10 Nov., 1966], No. 51191/67. Heading F2D. A remote shift control for vehicle transmissions comprises a manual gear lever 38 fast with a lever 46 which is freely mounted on a stationary pivot shaft 32 and rockable in the plane of the pivot to selectively engage an end 66 of the lever with apertures in levers 54, 76, 78 which are also pivoted on the shaft 32 and are linked to the shift forks (not shown). The first-second shift lever 76 has an aperture with an arcuate portion with which a transverse portion of the control lever 46 registers when its end engages the third-fourth shift lever 78, the arcuate portion of the aperture permitting the lever 78 to be pivoted independently of the lever 76. When the control lever is rocked to register its end with a second portion of the aperture of the lever 76, the control lever engages a detent plate 70. Further anti-clockwise rocking of the control lever to engage the reverse shift lever 54 requires pressure to be exerted on the manual shift lever in order to rock the detent plate anti-clockwise against the pressure of a spring 64. In an embodiment for a three-speed and reverse gear, two shift levers only are provided and are arranged on either side of the control lever which may have a flat end selectively engageable with apertures in suitably curved portions of the shift levers. This embodiment may be modified by pivoting the end of the control lever on the shaft 32 and engaging curved portions of the shift levers with an intermediate part of the control lever.

Title: Apparatus for spreading granular material especially fertilizer
IPC: B65G53/46
Filed: 1974-11-26
Abstract: 1495731 Spreading granular material on land NORSK HYDRO AS 26 Nov 1974 [26 Nov 1973] 51207/74 Heading AID Apparatus for spreading granular material such as fertilizer comprises at least one obliquely mounted, adjustably positionable tube whose lower end is connected to a compressed air source via a valve. The granular material is fed either directly to the upper end of the tube, or to a position adjacent the lower end of the tube. Repeated opening and closing of the valve causes pulses of compressed air to eject the material from the tube. In the first form of operation the material may flow continuously to the upper end of the tube from a hopper which may be provided with an outlet flap. The build-up of material in the tube is determinable by the frequency of valve operation. In the second form of operation the hopper 1 feeds to the bores of an indexable revolving barrel 2 the lowermost of which receives a blast of air from pipe 11 when aligned with the tube 8. The barrel can be driven by the compressed air so that the rate of firing can be governed by the air pressure. The spread of the material may be determined by pulse pressure or duration, position of the tube, a deflector plate adjacent the outlet end or by the provision of a flexible tube outlet end. The tube may be fixed or pivotally mounted on a rotatable base 12. If more than one tube is used, they may be arranged parallel to each other and may have different spread.

Title: Telephone subsets
IPC: H04M1/31
Filed: 1974-12-10
Abstract: 1480240 Substation circuits STANDARD TELEPHONES & CABLES Ltd 10 Dec 1974 53371/74 Heading H4K A push button subset is only supplied with power from the line once the handset has been lifted and a push-button has been depressed. The subset is of the type which includes MOS logic for converting markings produced by a push-button unit into loop-disconnect decadic pulse trains, and a capacitor charged from the line is used for powering the circuitry during the break periods of outpulsing. When the subscriber goes off-hook and a push-button is depressed, a key block changeover switch SF shorts out the speech circuit and connects the pulsing circuitry to the line current to charge capacitors C18 and C19 to a voltage determined by diode D12 and Zener diode D13. The MOS logic IC7 is reset via a reset circuit comprising transistors TR6, TR8, TB11 which is as described in Specification 1,437,917. The digit is fed into the logic IC7, which is controlled by a clock circuit (Fig. 2a, not shown) substantially as described in Specification 1,474,963. The MOS logic has storage capacity for up to 18 digits, and the stored digits are fed out under the control of the clock circuit via output 6 to a pulsing circuit comprising transistors TR7, TR9, TR10 which alternately supply positive and negative pulses to a bi-stable outpulsing relay R2B. A guard circuit comprising transistors T12, T13 ensure that the relay R2B is in its correct state before outpulsing begins, this circuit being supplied with line current via contact R2B of relay R2B. An off-normal relay R2A is similarly operated via output 5 of logic IC7, this relay being held operative during the period of outpulsing, the relay R2A taking over the function of switch SF. In place of the relay pulsing circuit, a transistor pulsing circuit of the type disclosed in Specification 1,404,078 may be used. The capacitors C18 and C19 supply power to the circuitry during the break periods of outpulsing: diode D18 protects the circuitry against voltage surges and resistors R35 and capacitor C20 form a spark-quench circuit.
