Title: Livestock handling system and method and apparatus therefor
IPC: B65D85/50
Filed: 1981-04-01
Abstract: Apparatus for handling small livestock such as chickens comprising open topped slideable drawers (12) in a rectangular housing (10) from which they are slid to allow for loading and subsequently for unloading onto a transfer conveyor (20). A roof (34) over the conveyor covers the open tops of the drawers as they move therealong to prevent the livestock from escape. An elevating platform (28) adjacent the conveyor (20) allows the housing (10) to be raised and lowered to allow the drawers to be pushed or pulled from the housing directly onto the conveyor. A method of collecting and handling livestock involves the step of filling the drawers in the housing with livestock, transporting the housing to a drawer unloading station where the drawers are removed from the housing onto a conveyor, for movement therealong beneath a roof which serves to cover the open tops of the drawers to prevent the livestock escaping, while they are transferred to a livestock unloading station at which the roof terminates. A conveyor for transferring open topped drawers containing livestock includes a roof below which the drawers are moved to prevent the livestock from escaping.
Patent GB-2078964-A (GB)
Title: Magnetic heading reference system
IPC: G01C17/38
Filed: 1981-04-30
Abstract: A magnetic heading reference system for a vehicle having a rotatable turret comprises a transmitter 100 for mounting on the turret of the vehicle to provide vehicle heading signals for an indicator system 210 to be mounted in the vehicle. In order to correct the signals to allow for rotation of the turret, the angular positions of the turret and a winding 102 in the transmitter, represented respectively by the phases of the outputs of a turret position transformer 201 and a control transformer 107 are compared by a phase detector 202. The output of the detector representing the phase difference and hence the difference in the angular positions of the turret and the winding 102, controls a motor 109 to turn the winding 102 until the phase difference is reduced to zero. The angular position of the winding 102 is transmitted to a similar winding 211 in a receiver 210 and thence to a visual display 212 for the display of the magnetic heading of the vehicle. <IMAGE>

Filed: 1981-05-08
Abstract: In the region of the radially outer edge of a friction disc a diaphragm spring (11) is arranged on the side of a first clutch part (5) remote from a second clutch part (1). The diaphragm spring (11) bears with intermediate region (15) on the first clutch part (5) and releases the first clutch part and the friction disc on traction loading of tongues (17) extending to the inner edge. From the outer edge of the diaphragm spring (11) tongues (21) protrude, which are secured directly to the second clutch part (1). Between the tongues (21) recesses (23) are provided so that the diaphragm spring (11) can be deformed elastically over an adequate distance despite rigid securing. In a second embodiment (Figs. 5 and 6 (not shown)) the tongues (21) are cupped to extend axially towards the second clutch part (1) and in a third embodiment (Fig. 7 (not shown)) the recesses have an arcuate form. The invention is said to achieve a clutch having no need for the usual cover or housing. <IMAGE>

Abstract: A non-contact method is provided for measuring the dimensions and form of an unknown surface by means of a transducer or sensor probe presented to the surface and determining the variations in capacity or electrical flux between said discrete capacitance electrode in the sensor and the adjacent unknown surface. To investigate the variations in the diameter and profile of a bore 33 a probe 30 having at least two angularly spaced capacitance electrodes 31 may be advanced along the axis of the bore and the capacitance values between each electrode and the adjoining surface measured. In another variant a single capacitative transducer probe may be moved over a surface to be measured. The probe may have an air supply duct discharging through one or more orifices adjacent the or each electrode to clean the unknown surface and (in the case of measurement within a bore) to provide a self-centering action. Several arrangements of electrodes and probes are described. <IMAGE>
