Title: Mechanical coconut dehusker
Inventor: SIVANAYAGAM S O SIVASAMBOO
IPC: A23N5/08
Filed: 1985-12-16
Abstract: The Mechanical Coconut Dehusker has been developed for the coconut plantation sector which is now facing an acute shortage of skilled labour. The coconut is placed in position on holder of the bottom pneumatic cylinder. When the button is pressed the 4 right angled cutters will move towards the centrally positioned 4 piece cross welded holder mounted above the coconut. The bottom pneumatic cylinder will push the coconut upwards to be in firm contact with the top holder and four right angled cutters. At this moment the top holder and 4 right angled cutters will be partially embedded in the husk. After the lapse of two seconds, the four right angled cutters will tear the husk away from the coconut and return to their original position while the top holder will also return to its position. The dehusked coconut is removed after the bottom pneumatic cylinder returns to its original location. <IMAGE>

Title: A circuit arrangement for an electronic ripple control receiver
Inventor: MUELLER BEAT
IPC: H04B3/54
Filed: 1986-01-30
Abstract: The circuit arrangement has an evaluation section 26 for evaluating the received remote control signals, switch members 35 which can be controlled by the evaluation section and a switching energy store 44 assigned to the switch members for the operation thereof. The evaluation section 26 is formed by a microcomputer and a circuit having a reference element 52 and a switching element 56 for monitoring the energy content of the switching energy store 44 is provided, which when the energy content falls short of the limit value, delays the control of the switch members 35 until this limit value is reached again. This delay takes place by temporary storage of the received remote control signals in the microcomputer 26. Several switch members can thereby be safely operated by a ripple control receiver without the energy content of the switching energy store or the performance of the current supply part having to be correspondingly increased. <IMAGE>

Title: Torque-controlled hydraulic coupling
Inventor: GARDNER JOSEPH
IPC: F16D31/08
Filed: 1988-11-02
Abstract: A torque limiter comprising an input member to which an input torque is to be applied, and an output member to which torque is to be transmitted from the input member, one of the two members comprising a first component, such as a housing 2, of a rotary hydraulic pump and the other of the two members comprises a second component, such as the rotor 4, of the hydraulic pump. The pump is arranged such that hydraulic fluid is pumped from a pump inlet port 15 to a pump outlet port 14 as a result of relative rotation between the two pump components 2, 4. The pump inlet and output ports are connected by a bypass passageway, and a pressure relief valve 16 is positioned in the bypass passageway so as to prevent fluid flowing from the outlet to the inlet port unless the pressure difference between the ports exceeds the relief pressure required to open the valve. The maximum torque which can be transmitted through the torque limiter is thus limited to the torque required to raise the pressure difference to the pressure required to open the valve 16. A second pressure relief valve may be arranged in parallel with the valve 16. <IMAGE>

Title: Radar Systems
Inventor: TAIT PETER D F
IPC: G01S13/22
Filed: 1990-02-28
Abstract: In a radar system, a high resolution waveform is used in which returns from a series of pulses are processed together by integration in order to obtain high resolution values of range and frequency shift of a target such as an aircraft 24. The range cell is sufficiently small that a range profile of the target is built up, and the frequency processing is also high resolution, and this enables a range frequency matrix to be built up, which can be compared, (25 Fig 3) with matrices of known targets, (24 Fig 3), in order to improve the chances of successfully identifying a target. A coarse/fine target resolution system is used (Figs 2, 3).
