Title: A control apparatus for a telephone
Inventor: DUDLEY ALBERT EDWARD FREDERICK
IPC: H04M1/31
Filed: 1968-09-06
Abstract: 1,237,703. Substation apparatus. A. E. F DUDLEY. 8 Dec., 1969 [6 Sept., 1968], No. 11246/68. Heading H4K. A control apparatus adapted for use in conjunction with a telephone comprises a drivemeans which from an idle state is selectively displaceable to drive the telephone dial or to operate the switch hook. The arrangement allows a disabled person such as a paraplegic to use a telephone. Two arrangements are described. In one (Fig. 3, not shown) the arrangement is within the normal telephone instrument housing. The drive means is an electric motor displaceable from a central idle position to a first position in which a gear driven by the motor engages a gear fixed to the telephone dial, and a second position in which the gear on the motor drives a cam disc which can be stopped in two different positions to operate and release the switch-hook respectively. The motor is displaced by a bellows controlled by inhalation and exhalation of the user. The other arrangement (shown) is intended for use with a conventional telephone set. It comprises an angled base 1 provided with cups 2 to receive the feet of the telephone and a pivoted plate 4 arranged to overlie the inclined face of the telephone. A shaft 11 carrying a gear 10 is journalled at one end to the plate and has its free end bent and carrying a rubber wheel 12. On the other side of the plate a drive motor is mounted within a housing pivoted to the plate. Two solenoids are arranged to be selectively energized by inhalation and exhalation pressure on a diaphragm to displace via a common armature the housing about its pivot point. The motor drives a gear 8 via an arcuate slot in the plate. With neither solenoid energized the gear 8 is in an idle position. With one solenoid operated the gear 8 is displaced into engagement with the gear 10 and the motor is actuated, causing wheel 12 to rotate. In one angular position of the wheel it engages the inclined face of the telephone and pivots the plate upwardly lifting a finger 5 from the switch-hook. By inhaling for an appropriate period the user can thus make and break the line loop at will. Energization of the other solenoid by exhalation causes the motor to be actuated and the gear 8 to mesh with a gear 9 which via a "finger" 13 operates the telephone dial. An indicator disc on the upper side of the plate 4 rotates with the gear 9 to indicate the extent of rotation of the dial.

Abstract: 625,707. Root-crop harvesters. KALLER. B. G., and KALLER, S. J. April 29, 1947, No. 11421. [Class 6(iii)] Relates to root-crop harvesting machines of the type comprising a rotary drum 17 driven, for example, from the road wheels 3, said drum having at least a part of its circumference close to the ground, and having around its circumference displacable tines which after passing a predetermined position are progressively retracted into the drum so that the points of the tines are close to or within the surface of the drum, while at another such position the times are projected outwardly to engage a beet, whereby the latter during the continued rotation of the drum is carried around to a release position where the tine is again retracted. The machine has a ploughshare 5, and according to the invention the ploughshare has an upper surface so shaped that the ploughed soil is turned sideways into a position such that the side of the soil strip is tangential to the drum at the position at which the tines are projected. A pair of spaced cutters 12 cut out the soil strip. Retraction of the tines is effected by a pin at the base of each tine engaging with a spiral track whereby the tine is gradually retracted against spring pressure; when the pin disengages from said track the tine is projected out. Steering handles locate the lateral disposition of the plough and associated mechanism which is raised by a handle 51. Spiked beets are cleaned by a brush working through a grid. On release of the beets they pass down a shoot 32 thence to an elevator 34 and finally to a collecting box 35 which periodically discharges the beets through a spring hinged bottom.
